D276's "low fog" is correct N64 behaviour — on hardware this quad also reaches the screen largely unfogged. +2. **The noise class is definitively the weave's painter (D276 owed step #3, closed).** `GE_D278C=1` collapse + `GE_PCDUMP=1500-1500:1`: band HF energy 14.8→2.9, mean 108→121; the band becomes a smooth bright haze. **No trees appeared without it** — the first unconfounded test (every prior A/B, D268/D273 included, was behind the opaque noise quad). +3. **Depth-race correction — D276's "occluder" framing was inverted.** N64 z/w: smaller = closer. At both confirmed weave points, ~278–310 of 356 `0x0c184b50` tris are CLOSER than the nearest noise tri. The open question is "why don't the closer textured cards show?", not "does the noise win the depth race?". +4. **Census at the weave points:** only 3 real classes reach `(0.05,0.10)`/`(0.25,0.15)`: `0xc81049d8` (IA8 noise painter), `0x0c184b50` (CI8, CPU-baked bimodal fog 25/255, gfog=0 — the tree candidate), `0xc8102078` (CI8). `0x00552048` (z/w=0) and `0x00504340` (z/w=-1) are probe artifacts. **`0xc8102078` ruled out as trees**: KEEPOML run draws 1.4M tris filling the lower half of the screen — terrain. +5. **The crux: `0x0c184b50` barely instantiates under deterministic boot.** `-level_36` + KEEPOML=0c184b50 → ~3–4 tris/frame, zero visible pixels, empty `texdump/`; the non-`-level_36` fog run had 720 covering tris.

Decoded within-run (D274's address-matching method): a **fully-opaque, high-frequency blocky gray static/noise texture** — nothing like D274's gradient wedge, nothing like a tree. **Every instance of this class uses the byte-identical UV window `u:0..64, v:0..16`** (a 2× wrap of its 32-wide tile) — this is **D265's very first "all cards sample the same u:0..64/v:0..16 window" observation, verified to the exact texel.** D269's second pass reframed away from that lead onto the CI8 classes without ever confirming the CI8 classes were what D265 had actually been describing. + +**A third class, `oml=0x0c184b50` (CI8), is present at every sampled point with a wildly erratic `z/w` (`-0.0381` to `0.9940`)** — when it does land in the normal distant range its fog is high (up to 255, plausible "fading into haze" tree behavior). Flagged as the likely real owner of the N64 reference's discrete tree silhouettes, with its own probable occlusion/billboard-orientation bug (not reliably reaching these pixels). **D236 may have two separate root causes, not one**: (a) the noise texture not being washed toward invisibility the way it should be, and (b) a genuine tree-sprite class failing to draw/occlude where it should. + +**Do NOT re-chase**: the D269 CI8 OPA/XLU pair as "the wall" (D276 — they aren't reaching 2 of 4 confirmed weave pixels; still worth keeping in the picture, just not the primary suspect), the mip-blend-quality-of-a-gradient-wedge theory (D274's leading candidate, now secondary — the newly-identified content is noise, not a smooth wedge, so blend quality is a weaker explanation than it seemed), the ARGB1555 palette swap (D273/D274), seq-based cross-run identity (D274), portal culling (D271). + +### NEXT STEPS for a fresh session (priority order) + +1. **Fog-correctness check for the `oml=0xc81049d8`/`fmt=3` noise class.** D276 measured average fog 39.5–63.3/255 at the two confirmed weave pixels — is that the *correct* N64 value for this vertex's world position (work out what `fog_mul`/`fog_offset`/z *should* give), or a computation bug in this specific draw path? This is the cheapest, most direct next test — the data is already logged (`scratch/d275_pix_run.log`), no new probe needed, just the offline math. +2. **Attribute and understand `0x0c184b50`'s erratic `z/w`.** Extend `GE_D270PIX` (already list-capable) to a couple more points squarely on the N64 reference's visible tree trunks/canopies and see whether this class is the one meant to be there; if so, root-cause why its `z/w` swings from `-0.04` to `0.99` (billboard basis computed from a bad/momentarily-invalid camera vector is the leading guess, unconfirmed). +3. **Re-run the class-isolation A/B** (owed since D274, now with D275's kept-counter and D276's corrected target classes: `0xc81049d8`/fmt=3 vs. `0x0c184b50`, not the D269 CI8 pair) at the tick-aligned window established this pass (`GE_PCDUMP=1300-1700:25` — all 17 frames confirmed non-black/weave-consistent, so use any tick in that range, not just 1500). +4.

It A/Bs the CI4/CI8 palette-entry +decode: standard N64 ARGB1555 vs. the inherited PD-shifted layout, with a +comment theorizing the shift flips an alpha-test outcome for the wall's +palette. **Tested it against the reference this session: RULED OUT.** Same +frame, `GE_D273=1` vs. unset — the wall's herringbone pattern is pixel-eye +identical either way (`scratch/d273_fixed_1500.png`), while unrelated CI8 +content broke (snow path → cyan/magenta moiré, viewmodel hand → teal +skin). Do not enable `GE_D273`; do not pursue this decode swap further for +D236. Full writeup + the process-gap note (an investigative lead sat +undocumented across a handoff boundary — `git diff` suspect files, don't +trust the day's HANDOFF narrative as a complete uncommitted-work inventory) +in findings §F **D273**. + +**Open discrepancy this reference exposed — RESOLVED by D274, see above.** +D269's offline CI8 decode of these wall cards described "soft vertical +gradients / sparse blobs." What's actually on screen is a sharp, regular +herringbone weave. This was flagged as a possible decode/content bug; D274 +traced it to a palette-byte-order mistake in this session's own offline +analysis script, not a port bug — reconciled, no discrepancy. + +### D272 (M-130) — still holds + +This session reviewed the D271 negative outcome and executed HANDOFF's own +next-step #1 (the per-card S/T audit) instead of guessing further. Result, +in full in findings §F **D272** (M-130): + +- Extended the tri-probe family with a new `GE_D272` (env-gated, budget 200, + filtered to D269's exact two wall-card `oml` classes) that dumps raw + per-vertex UV (texel units) + tile fmt/siz/wh/mask/shift for every matching + band tri. Built + ran against `-level_36` (boot camera), 3 iterations to + get the filter right (first pass had no oml filter and was swamped by + unrelated sky/floor geometry in the same screen band; that unfiltered data + is what likely produced D265's "cards all sample the same u:0..64/v:0..16" + read — several *unrelated* degenerate-UV draws in that band really do + share one (0,0) UV, but they are not the wall cards). +- **Both classes confirmed CI8** (`fmt=2 siz=1`), matching D269. +- **UV windows are NOT identical across card instances** — small (~0.3–1.6 + texel) but real per-vertex jitter between cards sharing the same bound + texture. This kills the "converter/tile-setup collapses every card onto + one window" theory outright. +- **The XLU class's U range is ~143–145 texels — ~4.5× its own tile's + 32-texel wrap period.** Read `tools_pc/d43_emit.py`'s `emit_main_vtx`: the + vertex S/T fields go through a plain BE→LE 16-bit byteswap, no scale/ + offset/reinterpretation (same pattern as every other `Vtx` field) — **the + wide wrap cannot be a converter bug; it must already be authored in the + ROM.** This also rules out the D108–D112 `put_f32`-byte-reversal bug class + for this specific case (verified by reading the code, not by inference). +- **Conclusion: the wide horizontal texture wrap is Rare's own design** + (tiling one CI8 texture ~4.5× across a long background quad), so the wall + is not a UV-windowing or converter bug.

Fix: +guard `lim` → `1e38f` (non-finite-only); finite garbage now clamps/culls in +`bgRectIntersect` exactly as on N64. Verified: `d106Fallback` → 0, room +drops traced per-portal to N64-matching empty clamps, no crashes. Full +write-up: findings §F **D271** (M-129). + +**USER RE-TEST RESULT: NEGATIVE — "it's still not right, trees are a big +wall rather than the texture being mapped correctly."** So culling was a real +N64-divergent over-draw (the fix is kept — it's a fidelity fix, do NOT +revert) but it is **not** the wall's root cause. The user's phrasing points +at texture mapping. + +### State of the hypothesis space (evidence trail D265 → D269 → D271) + +- **What the wall is** (D269): CI8 32×32 billboard cards, two draw classes + per room stream (OPA oml=0xc4112078 + XLU oml=0xc41049d8), both BILERP + + TEXTLOD-on + perspective-corrected + 2-cycle, omh FOG bit set. Card + contents decoded from ROM: soft vertical gradients / sparse blobs (index + histogram concentrated at low indices 6–14). NCC of every dumped card vs + the captured frame < 0.35 — the cards are not visible as rigid copies. +- **Ruled out**: IA4/IA8 decode (zero IA4 draws from this camera; the three + IA8 images are noise/mast sprites), the blend pipeline (force-alpha A/B, + D268, proves texel-alpha compositing works end-to-end), fog combine (no + blend cycle in play references `CLR_FOG`/`A_FOG`, so the omh FOG bit is + inert), and now portal-culling over-draw (D271 — fixed, wall unchanged). +- **TOP SUSPECT: per-card S/T / UV windowing.** D265 noted *"all captured + cards sampled the same u:0..64/v:0..16 window — confirm against N64"*. + If N64 gives each card its own S/T window into a shared tree-silhouette + texture and the PC samples one region for every card, the result is + exactly a repeating sheet = the reported wall. Mechanism candidates in + order: + 1. **Model DL vertex S/T data** — what `tools_pc/d43_emit.py` emits for + these cards' S/T (s16 fixed-point; format depends on tile line length). + A conversion bug (byte-swap/scale/offset) collapses all windows onto + one region. The converter is the usual suspect class here (cf. + D108–D112 `put_f32` byte-reversal). + 2. **Tile setup in the DL** (`gsSPSetTile` → image size, foldS/foldT, + tcShift) — wrong tile dimensions for this CI8 surface would map every + card's S/T into the same window. + 3. **fast3d UV handling** in `port/fast3d/gfx_pc.cpp` (tex_lod path, + GL_REPEAT period, fold math). +- **N64 ground truth**: `docs/img/bugs/d227-surface-emulator-ref.png` — a + smooth bright band with *sparse organic tree clusters* centred x≈0.35–0.75, + NOT a continuous sheet. `mupen64/` (local emulator, Rice plugin) is + available for more reference captures if needed. +- **Side suspect (palette)**: the archived third-pass noted the port's + `palette_to_rgba32` reads a=bit0, r=bits15:11, g=bits10:6, b=bits5:1 vs + the standard N64 A=15, B=14:10, G=9:5, R=4:0 — verify against the RDP + spec; if wrong it affects every CI texture and would turn a tree image + into an unrecognizable gradient blob (consistent with D269's decode). + +### NEXT STEPS for a fresh session (priority order) + +1. **Per-card S/T audit.** Extend `GE_D266W` (band-gated tri probe in + `gfx_sp_tri1`) to log per-vertex S/T + tile index + image size/line for + the wall card classes (oml 0x0c184b50 / 0xc81049d8 family). The deciding + question: do distinct cards carry **distinct** S/T windows, or identical + ones? Identical on PC → compare against what the ROM model data says + (decompiled DL words) — converter bug if they differ there. Distinct on + PC but all landing in the same texture region → tile-setup/fold bug. +2. **Decode the CI8 card + palette to an RGB PNG and LOOK at it** + (`scratch/d269_decode.py` exists; `GE_TEXDUMP=1 GE_TEXRAW=1` now also + writes `.pal` files). If it's a tree silhouette → S/T windowing owns the + bug. If it's a gradient blob → texture data or palette decode is wrong. +3. **Cross-check `d43_emit.py`'s S/T emission** for these cards against the + raw ROM model bytes (byte order, fixed-point format). +4. If PC S/T windows are distinct and sane: fall back to TEXTLOD/mip + sampling (does the port generate mips for these tiles? which min filter?) + and the palette item above. +5. Keep the D271 fix + all probes until the wall closes; then remove the + probe sets together (D266–D269 + D271). + +**Do not re-chase**: AC_DITHER/alpha-compare math (D266), IA4/IA8 decode, +blend pipeline, fog combine, portal culling (all ruled out with evidence — +see findings D265–D271). + +**Separate, still-open, NOT the same bug**: D176(a) — the Surface sky +rendering dark instead of the expected bright horizon band. It has its own +NEXT STEPS list (non-standard combine encoding `m1=8`, IA16 cloud texture) +in the "third pass" archive below. Do not conflate the two threads. + +### D271 evidence (pre-fix; reproducible, 3/3 runs) + +Probe: `src/game/bg.c`, small `#ifdef PORT` additions, all inert unless +`GE_D271`/`GE_D104` are set (uncommitted — `git diff src/game/bg.c` to see them): + +1.

Our quads render dark. **The bright band IS the sky** (`skyRenderFull`/`skyRenderTri` → `skyPortRenderPoly` in our PC port), which renders dark in our build due to a texture/S-T/combine issue. + +### Key findings this session (all env-gated probes, inert when unset) + +| Finding | Evidence | +|---|---| +| KILLALL: band → pure black | Band IS tri1 geometry (not clear-color) | +| No single CI8 class explains the dark band | A/B skip meandiffs only 4–11 levels | +| ROM card data is genuinely dark | Both port + standard N64 palette decode give lum 77–172, top indices → near-black (0–42) | +| No bright fog color exists | 71,912 G_SETFOGCOLOR calls over ~1300 frames: all dark blue-gray (96,96,128), (0,0,0), etc. | +| Quad A (oml=0x00552048) IS the sky quad | `skyPortRenderPoly` sets clip.z=0 by construction; IA16 64×64 cloud tile; re-imported every frame | +| KEEP-A test: band = fog color exactly | pixel(0.15,0.06) = (98,97,128) ≈ fog (96,96,128).

The m1 field position/width may differ from standard fast3d. Search: `grep -n "combine\|COMBINE\|oml\|OML\|setCombine\|dp_set_combine" port/fast3d/gfx_pc.cpp | head -50`. **DO NOT grep gbi.h — it's been exhaustively searched; the answer is in runtime code.** + +2. **Decode the sky's IA16 cloud texture** — find which texdump rNNN corresponds to quad A's 64×64 IA16 import (line=64B, fmt=3). Check if it's bright (haze gradient) or dark. If dark → texture import bug. If bright → combine/S-T issue. + +3. **Check S/T fold correctness in `skyPortRenderPoly`** — the cloud tile is 64×64 with GL_REPEAT period=64. Verify foldS/foldT + tcShift produce correct texel sampling. A wrong fold could sample a dark region of an otherwise-bright tile. + +4. **Investigate quad B (z/w=-1) rendering failure** — N64 RDP clip range is [-w,+w], so z/w=-1 may still rasterize on N64. If this is a second sky layer, our port's near-clip or projection handling discards it. + +5. **If mupen64 path is pursued**: use `mupencheat.txt` to write rmon token at fixed RAM address (find where `rmonGetToken` reads from in decompiled code), run with level_36, capture via Rice plugin screenshot.

Headless is fine for the first pass (`GE_INPUTSCRIPT`; note ~2 controller reads per render frame — time scripts empirically, see D261's pulse-train notes). +3. Instrument: env-gated probe logging the intro-record state machine (which record index is active, its tag, and the beat's trigger/sequence counters) each tick for the first ~60 s; compare against what `UsetuparkZ`'s intro array actually contains (dump the rebase'd records once at load — offsets are relative to the blob start). +4. Diff behaviour vs a level whose opening beat DOES work (e.g. Dam `-level_33`) to isolate "Facility data" vs "general beat machinery". +5.

Own branch + PR per item; user merges. + +- **Task 0 — DONE, PR #77 open** (`feat/deck-first-run-preset`): Steam Deck first-run preset (the section further down describes it). Caveats: existing-ini Decks need `-fresh`/F10; 16:10 stretch. Real-Deck test owed from the CI artifact. +- **Task 1 — DONE, PR #78 open** (`feat/f10-game-toggles`): `Game.NoHitFlash` (D232) + `Game.SkipIntro` (D216) as ROW_TOGGLE rows after Screen shake. Deliberately excluded `Video.FixMipTextures`/`Video.WrapFix` (opt-in fidelity bug-fixes, not preferences). User-verified live: rows render/toggle, persist to ini, SkipIntro=1 boots to file-select. +- **Task 2 — DONE, PR #79 merged** (`feat/all-unlocked` @ `f49331c1`): `Game.AllUnlocked` option (default flipped OFF for the v0.2.0 final: with it ON a fresh save loads audio at volume 0, D259; F10 toggle unchanged). All levels at all difficulties + 007 mode via the two live `LEFTOVERDEBUG` RAM flags seeded in `main.c`; eep-shim read-time patch sets all 20 cheat-unlock bits **and** fills empty completion times (0x3FF) with per-slot `fileGenerateCRC` recompute — the completion half is required or enabling any cheat locks every level in mission select (`g_AppendCheatSinglePlayer` → COMPLETED-only; user repro "could only do Silo"). User playtest passed (time-modifying cheats untested). Full mechanism + the `times[80]`-vs-76 mirror pitfall: findings D257. +- **Session end (release plan agreed with user):** all eight known issues in `.github/release-notes.md` walked one by one — **all confirmed still open** (wording-only changes for final; nothing removed). Plan for next session, in order: (1) user merges #77/#78/#79; (2) Task A README/pages + media pass (docs-only PR; commit referenced media, delete `scratch-gdb-cmds.txt`; user says pull new images from the contact-sheet montage) — **must land before the tag** because bundles ship their own README.md; (3) Task B finalize `.github/release-notes.md` for v0.2.0 final (``→`0.2.0`, drop pre-release, rewrite blockquote, new What's-new bullets incl. explicit AllUnlocked-default-ON bullet; "all 21 missions completable" becomes a claim only if the user does a full campaign run); (4) tag `v0.2.0` → CI re-cuts assets + release body → **user publishes/flips to final** (hard rule: never publish without explicit approval); (5) Task C = D236 billboard diagnosis (half-day budget, stop-and-report).

Next finding label: D258. + +--- + +## v0.2.0-pre: at the publish gate (2026-09-13 evening) — D253/D254/D256 fixed, D255 narrowed; user publishes the draft when ready + +**HARD RULE (user-stated): do NOT publish/deploy the release without explicit user approval.** CI only ever creates/updates the *draft*; publishing is manual on the GitHub Releases page (or `gh release publish` only if the user explicitly asks). + +**State:** tag `v0.2.0-pre` = `1e88fea0` (notes-only bump over `8d4e7443`, the code state). Draft release live with 4 assets + sha256s; CI re-cut of `1e88fea0` was in progress at session end (two push runs, ~10 min) — **verify both green and that the draft body shows the final notes** (D256 bullet, updated D255 line) before telling the user it's ready. The code in the assets is byte-identical to what the user already playtested on Windows + Deck. + +**Session work (all committed/pushed on main):** +- `c1b8560c` **D253 FIXED** (ABI-class): `stanCheckLinkedSpecialTile` prototype float/s32 mismatch — SysV x86-64 ABI divergence, N64 codegen unaffected. Deck-verified by user (got past the crouch tile). +- `ce59e856` **D254 FIXED**: Linux crash handler re-entered on SIGABRT and truncated its own log. Now: re-entrancy guard, `_exit(128+sig)`, FAULT ADDR (`si_addr`) + full register dump (Rax/Rcx/Rdx/Rsi/Rdi/R8–R11/Rsp/Rbp) from ucontext in `ge007.crash.log`. Note the log is written to **CWD**, not exe dir — a launch from an unwritable CWD loses it. +- `8d4e7443` **D256 FIXED + Deck-verified by user** ("it fixed the save on steam deck"): POSIX `$S` in `port/src/system.c sysResolvePath()` now mirrors the Windows branch — CWD `data/` else exe-dir `data/` via `readlink(/proc/self/exe)`, best-effort mkdir. This also explains the Deck "draw distance is low" report: config never persisted, every launch started at defaults (DrawDistance 100% = faithful N64 far-clip). +- `1e88fea0` release notes: D256 bullet added, D255 line updated, "no known crashes" claim dropped from the blurb. + +**D255 (OPEN, intermittent) — current understanding:** SIGSEGV in `sub_GAME_7F09BAC4` (`vtxstore.c`, PD name `vtxstore_fix_refs`) during heavy firefights on Deck. Called from `vtxstore_tick` (7F09BBBC) whenever vertex batches merge; walks active PropRecords with type==1 (PROP_TYPE_OBJ), reads `ObjectRecord.model` (offset 0x14) via a **32-bit zero-extended load** (decompiler mislabels the union member as `ChrRecord.chrflags`), then derefs `model->obj`. **Truncation is RULED OUT:** all game memory (mempool banks incl. MEMPOOL_STAGE where Models/records live) sits in the emulated N64 DRAM window 0x70000000–0x70800000 (< 4 GB; `tlbmanageGetTlbAllocatedBlock` → 0x70700000, n64stubs.c). Remaining mechanism: **stale/NULL model pointer on an active OBJ record** (destroy-path ordering — crate/effect dies, record lingers or its memory is reused when the merge tick lands in the window). `objInit` only sets model when non-NULL; the NULL-model path found (`chr.c:1890`) is CHR-only (type 3, skipped by the walk). Next Deck crash's `ge007.crash.log` decides: FAULT ADDR == 0x10 → NULL model; other small/garbage → reused record memory; Rax = the ObjectRecord. Fallback if ambiguous: env-gated probe in `vtxstore_tick` dumping each active OBJ's model pointer per merge (GE_D51/GE_D250 precedent). User has since played Facility on Deck without crashing — it's intermittent; tell them to grab the log before the next crash overwrites it. Any level with object churn works, not just Facility. + +**Deck testing facts:** local WSL builds are NOT Deck-compatible (glibc 2.43 vs SteamOS ~2.38) — only CI artifacts (ubuntu-24.04) ship to Deck; WSL is for debugging only. User's Deck flow: SFTP the tarball from the draft release, unpack, `data/` with ROM + generated sidecars (`prepare-assets`), non-Steam game shortcut. **Sidecar gotcha found while testing:** a `data/` without `pccg-*/`+`pcmodels-*/` starts fine but faults deterministically in `load_bg_file` (bg.c:865) on level load — expected degraded mode (reserve fns warn "stage loads will fault"), not a bug; don't chase it. + +**Tree hygiene:** untracked in repo root/docs: `docs/img/shots/CONTACT-SHEET.jpg`, `docs/img/shots/manifest.csv`, `docs/media/goldeneye-*.gif/.mp4` (playtest media from the gallery pass) — decide keep-vs-gitignore next session. `scratch-gdb-cmds.txt` at repo root is throwaway. + +**After publish:** D255 register capture (above); then post-release backlog per findings index (D252 rainbow particles — user said document-only for this release; F10 bottom-row duplicate; D243/D230/D245/D246/D75). + +**Post-gate local branch `feat/deck-first-run-preset` (unpushed, "final v0.2.0 touches"):** Steam Deck first-run preset + better default view distance, per user request. `getenv("STEAMOS")` in `main.c` → `videoApplySteamOSDefaults()` (`port/src/video.c`) before `configLoad()`: Fullscreen=1, Window 1280×800 (Deck native), VSync=1, MSAA=4, DrawDistance=150, LodDistance=150. First-launch-only by construction — no ini → configLoad's first-run path saves the preset; existing ini always wins (verified: user values 220/MSAA 2 survive a STEAMOS relaunch; note `Video.DrawDistance` clamps to min 100, pre-existing). Verified on Windows with `STEAMOS=1` from an isolated CWD: first-run ini seeded correctly, window opened 1280×800, repo's live `data/ge007.ini` untouched. Caveats logged in code + README Deck section: 16:10 panel stretches the 4:3 render (letterbox = parked WIDESCREEN-FOV-PLAN); a Deck that already has an ini (user's playtest one) needs `-fresh` or F10 to pick the preset up. Draw-distance context for item 2: default 100% is N64-faithful authored fog/fade (the Dam lock fade-in is console behaviour); `Video.DrawDistance` scales far fog + prop/char fade cutoffs (`bgfog.c`, `propobj.c`), `Video.LodDistance` scales LOD-swap distance (`model.c`) — both F10-settable and persistent since D256. + +--- + +## v0.2.0 pre-release cut (superseded by the section above, 2026-09-13) — docs + release artifacts; Steam Deck was the final blocker + +**Task:** cut the v0.2.0 **pre-release** (Windows + Linux/Steam Deck). User +will do a full manual playtest in lieu of the `verify.sh` sweep. + +**Done this session (all committed on main):** +- `f3882040` D194 closure recorded (M-123); `436e7c82` D251 F10 overlay QoL pass (ships WITH the intermittent 4K-fullscreen ghost-row bug — user decision, logged as known issue). +- `4f6092dd` legacy always-grab mouse mode removed entirely (D192 + D239 closed): `Input.MouseCaptureMode` gone from `input.c`/`input.h`/`optionsoverlay.c`; click-to-lock is the only capture mode. +- Docs: ROADMAP-1.0.md got a "Task 1 status addendum (v0.2.0 pre-release cut)"; README Status rewritten + Download section now leads with the two v0.2.0-pre bundles (asset names follow `bundle-*.sh`: leading `v` is stripped, so `goldeneye-pc-port-0.2.0-pre-{win64.zip,linux-x86_64.tar.gz}`) + new Steam Deck subsection. + +**Remaining before tag:** +1. `tools_pc/bundle-linux.sh`: bundle SDL2 `.so*` into the tarball with an `$ORIGIN` rpath (mirror of `bundle-win.sh`'s DLL allowlist) so the Deck sideload is turnkey — README already claims this; make it true. +2. Build both bundles from the tag commit: `tools_pc/bundle-win.sh v0.2.0-pre`, `tools_pc/bundle-linux.sh v0.2.0-pre` (Linux bundle: cross-check on a real Linux box or CI artifact). +3. **Steam Deck test session (~1 hr, needs the hardware — who has the Deck?):** install tarball via USB, Facility walk+fire (D203 repro profile), gamepad check, `Video.DisplayFPS` on Dam + Streets, grab `ge007.crash.log` if anything faults. +4. Tag `v0.2.0-pre`; publish pre-release with known issues: D243 (Dam end race), D230 (music quality), D245 (water seam), D246 (edge strips), D197 (face wrap on Silo), D75 (front-end models), the D251 4K ghost row, and "not yet verified on real Deck hardware". Flip to final after the user's playtest passes. + +**Environment:** build as before (`/c/msys64/usr/bin/bash.exe -lc 'export PATH=/c/msys64/mingw64/bin:$PATH; cd /c/Users/james/Source/Repos/gh-fullhist && ./build-pc.sh ntsc-final'`). CI (`.github/workflows/ci.yml`) builds Linux per push — the `linux-build` job's artifact is the bundle source for the tarball if local Linux testing isn't available. + +## F10 overlay QoL session (2026-09-13, shipped in v0.2.0-pre) — D251; known bug: intermittent 4K-fullscreen "repeat of top entry" at panel bottom (MSAA×fullscreen driver suspect, unverified) + +**Task:** QoL pass on the F10 in-game options overlay (`port/src/optionsoverlay.c`, port-layer only). User is playtesting live; an instance I launched was PID 11508 (may be dead by now — just relaunch from repo root, see commands at bottom of this file). + +**Done + verified building (D251 in findings.md):** +- Scrollable panel: `maxVisibleRows()` / `s_visIdx[]` / `s_scroll`; 17 rows no longer overflow the 240-tall in-game space. `s_sel` is a **visible-list index**, not a row index. +- MSAA cycle wraps both directions: `idx = (idx + dir + 4) % 4`. +- Auto-coupled % rows (Draw distance %, LOD distance %) hidden while their auto toggle is ON (`hiddenIfOn` → resolved to `hidePtr` at init). +- Nav (wheel + arrows) **clamps** at both ends (no wrap). Sliders clamp; only discrete cyclic rows (MSAA/enum/res/toggles) wrap. +- **Hover-to-highlight removed entirely** — mouse movement never moves selection or scroll; only click / wheel / arrows do. (The old hover→select→scroll-shift feedback loop near list edges was a likely source of the "duplicate row" twitch.) +- Sensitivity link: `Input.SensLink` config key (default ON) in `port/src/input.c`; `rowSet()` scales AimModeSens=38 : MouseTurnSpeed=50 bidirectionally with an `s_linkDepth` re-entrancy guard. Overlay-side only (direct ini edits bypass it — by design). +- "Mouse aim speed" row repointed from inert `Input.MouseAimSpeed` to the active GEPD knob `Input.AimModeSens` (uiMin 1, uiMax 80). New "Link aim/turn sens" toggle row added. + +**OPEN BUG — REASSESSED (wrap theory dead, local repro clean):** launching at 4K (user's monitor 3072×1728; live ini `Fullscreen = 1`, `MSAA = 4`), opening F10 shows a **dark, unselectable repeat of the top entry ("Fullscreen") at the bottom** of/under the panel. Only in that mode. + +**Reassessment (fresh trace, this session):** +- `gfxFramebuffer` has **zero readers** — the textured-quad present (`G_SETTIMG_FB_EXT`/`select_texture_fb`) is never used by the game. Presentation is a full-frame `glBlitFramebuffer` from the same-size MSAA FBO to the default framebuffer (fb index 0 is reserved for the window; `different_size` is structurally always false since both dims come from `gfx_current_window_dimensions`). No UVs in a blit → **UV-wrap is impossible; that theory is dead.** Do not apply the CLAMP_TO_EDGE fix — it would change nothing. +- The overlay DL draws each visible row exactly once, in-bounds, own scissor (0,0,W,H). `aspect_mode` is never set by GE (no `G_ASPECT*` anywhere in src/), so 16:9 just stretches RATIO_X≠RATIO_Y uniformly through viewport+scissor — no letterbox offset, mouse mapping stays correct. +- **Local repro attempted and CLEAN:** windowed-maximized 16:9 (2987×1705) + MSAA=4 + `GE_OPTIONSOVERLAY=1` + `GE_PCDUMP` on `-level_09` → no ghost row. The FBO/MSAA path alone is not the trigger. +- Remaining variable: **true SDL fullscreen on the 3072×1728 display** (driver/display-level suspect — that resolution is non-standard; check Windows DPI scaling vs actual drawable size if it persists with MSAA off). Also removed: the `GE_OV_FORCE_SEL` temp debug hook (done this session). + +**User update (logged, NOT fixed yet):** the ghost is *intermittent* across launches; user suspects the Draw/LOD distance % rows appearing/vanishing when their auto toggles flip (`hiddenIfOn` visible-list resize). Unverified — emit and input both rebuild `s_visIdx`+scroll together each frame, so if it's this, the window is the transition frame itself. User: so far it appears on *first open* of F10 (not only after an auto-toggle flip). **Next (needs the user, ~1 min):** bisection on their machine — F10 → set **MSAA = OFF** (tagged restart) → restart, still fullscreen 4K → open F10: ghost gone ⇒ MSAA×fullscreen driver interaction (park as display-specific, maybe try a standard 2560×1440 fullscreen); ghost persists ⇒ pure-fullscreen path bug, then instrument `gfx_current_window_dimensions` vs `SDL_GL_GetDrawableSize` at frame start in fullscreen. **Also logged (QoL follow-up):** make the auto-linked % rows visually subordinate to their toggle (indent / dimmer colour) so the pairing reads obviously. + +**Environment / state notes:** +- User's live `data/ge007.ini` already has `Fullscreen = 1`, `MSAA = 4` (backup at `/tmp/ge007.ini.bak` — I did not modify their ini). Monitor: single display 3072×1728, window fullscreen at 0,0. +- `ppm/user4k.png` exists from a PowerShell `CopyFromScreen` capture but was taken with the overlay **closed** — low value; user asked to stop analyzing captures. +- Build: `/c/msys64/usr/bin/bash.exe -lc 'export PATH=/c/msys64/mingw64/bin:$PATH; cd /c/Users/james/Source/Repos/gh-fullhist && ./build-pc.sh ntsc-final'`. Launch from repo root: `./build-pc/ge007.x86_64.exe &` (needs `./data/` ROM). +- Design doc for the overlay: `docs/dev/OPTIONS-MENU-PLAN.md` (approach C: port-layer overlay, zero src/ menu edits). + +## M-123 (2026-09-14) — D194 ① log mined + wrap-spike fixed; spazz NOT in our writes (they're rock-stable); next: live capture with the new residue/autoaim logging, then user A/B playtest + +**Worked ① (crosshair/arm spazz) per M-122's plan.** + +**Log mining (`d194_gepd.err`, 1964 gepdaim lines) — key result: the port's own writes are rock-stable.** Zero crosshair/camera jumps while aim is held (scan: consecutive gepdaim lines with btn&0x2000, Δcam>3° or Δcross>0.5 → 0 events). Every large camera delta in the log turned out to be user hipfire stick swings between polls (verified against the interleaved `cont0` stick lines — e.g. the ±20–38° "jumps" at gepdaim indices 1183/1348 follow stick ramps to (80,26)). Exactly **ONE true anomaly**: a +359° one-tick spike in raw `vv_theta` (cam 0.5 → 359.7 at log line 534) — our own `[0,360)` wrap of the edge-scroll accumulator firing when a leftward scroll crossed zero. **Fixed: the two wrap lines are deleted** (`port/src/input.c aimGepdCompute`) — GEPD does bare `camx += ...`, and the game never wraps `vv_theta` in on-foot play either (`bondviewApplyVertaTheta` only sin/cos's it; tank code is the sole wraper). **Correction to M-122's suspect (a) mechanism:** the theory that the spike feeds the crosshair via `speedtheta` does not hold — `speedtheta` comes from stick input (`bondview2.c:6056`, `analogTurn/70` or the aim-turn easing), never a `vv_theta` delta; all solo-play consumers of `vv_theta` are sin/cos or `(360−θ)` rotations (raw-delta consumers at bondview2.c:1361 swirl / :9397 backstab check are MP-only). So the wrap fix is correct-vs-GEPD hygiene, but likely NOT the visible spazz. + +**Also resolved from static reading:** suspect (b) tick ordering — our write runs BEFORE `bondviewProcessInput` each tick (`osContStartReadData → inputComputePad`, libultra.c:1094), vs GEPD writing after game code; but the displayed fixed point is `X·damp+turn` either way in steady state, so ordering alone can't cause spazz. Suspect (c) 2px deadband — does not apply to the GEPD path (deadband lives only in the legacy fallback). Suspect (d) centre-spring nudge — ~0.1–0.3° over its 2 ticks, negligible; kept (clears `docentreupdown`, which must not fight aim). + +**Remaining live suspect for ① (now instrumented):** the game-side turn terms added on top of our overwrite every tick — `turn_x = autoaimx | speedtheta*0.3`, `turn_y = autoaimy | −speedverta*0.1` (HONEY block bondview2.c ~6140-6170 → `caclulate_gun_crosshair_position_rotation` gunfire.c:4819, which does `pos = pos*damp + turn`). Prime suspect: **auto-aim pull oscillating as lock-on jitters** (displayed crosshair = our value·damp + autoaim term; matches "worst near enemies"). The gepdaim log line now also prints `game=(resX,resY)` (pre-overwrite residue = last tick's `pos·damp+turn` — the gap vs our write IS the turn term), `aa=(autoaimx,autoaimy)`, `st=`/`sv=` (speedtheta/speedverta). **A live capture while aiming at guards will confirm or kill it in one look.** + +**Item ② (FPS drop):** checked `sysLogPrintf` — plain buffered `fprintf(stderr)` (port/src/system.c:87), cheap; the ≤10fps-while-aiming session's correlation with GE_INPUTLOG is probably coincidence, but the control retest (logging OFF) still stands as first step. Frame-time lines in the old log are too sparse to use. + +**Repo state:** `fix/d194-mouse-dt-decouple` @ ef49d9e6 + UNCOMMITTED: `port/src/input.c` (wrap removal + extended gepdaim log), `docs/dev/findings.md` D194 status (M-123 note). Build clean, `-level_09` headless sanity run crash-free (gepdaim lines only fire while aiming — needs live mouse). `d194_gepd.err` still in repo root (mined; can be deleted once the new capture supersedes it). + +**M-123 update (user playtest of `a7059c46`+`bd6caef5`, sens 25):** user verdict — **"looks good... other than sensitivity we're good, 95%."** ① is ACCEPTED as-is (residual arm/gun/crosshair glitching deemed playable; not worth another round). The `d194_gepd2.err` capture came out EMPTY (PowerShell 5.1 `2>` redirect on a native exe didn't capture stderr — use the `Start-Process -RedirectStandardError` form from M-122 if a capture is ever needed again). Remaining work = **③ sensitivity co-tune, live**: ini now at `GepdSens = 30` (was 25; code default also 25 — resync the default once the user lands on a number they like). Tune loop: close game → edit `data/ge007.ini` `GepdSens` (1–80) → relaunch; no rebuild needed. If 30 is too fast, bisect 27/28. Once settled: update code default + this note, then re-test ② (aim-mode FPS with logging OFF — never properly controlled yet) before considering the D194 branch merge-ready. + +**M-123 CLOSED (this session):** sensitivity co-tuned live and **merged to main as `f239adf5`** (`fix/d194-mouse-dt-decouple`, branch deleted). Final state: hipfire gain recalibrated (`MouseTurnSpeed` default 100→50; the old gain saturated the game's quadratic natural-turn curve at ~13 px/poll = always full 315°/s, the "too fast when I leave aim mode" complaint); `MouseSensitivity` master now scales aim mode too so both modes move in lockstep (D238 step-1); defaults set ~25% above the user-approved match point (`AimModeSens = 38`, `MouseTurnSpeed = 50`, master 100 = calibrated baseline). User-facing key renamed `Input.GepdSens` → `Input.AimModeSens` (community name; old key kept as deprecated alias, internal `gepd*` identifiers kept for GEPD provenance). **D194 is now fully closed:** ② (aim-mode FPS) resolved by user report — "no performance [issue] is good now" during the calibrated playtest sessions; the original ≤10fps complaint did not recur, so it's closed on user evidence (the formal logging-off control was never run; revisit only if an FPS regression appears later). Playtest logs `d194_gepd*.err` deleted. Findings/HANDOFF closure notes are recorded but **uncommitted by user request** — commit them with the next change. + +--- + +## M-122 (2026-09-13) — D194 GEPD-mirror aim IMPLEMENTED + user-confirmed "mechanically works"; three items left: ① crosshair/arm spazz glitch, ② aim-mode FPS drop (perf.ps1), ③ sensitivity tuning. Next session starts at ①. + +**The aim rewrite landed.** After four failed stick-synthesis models (absolute → dial → relative-angle → velocity-mapped stick; see M-121 + commits `8a8d066b`/`650b7f63`/`7f65ed15`), the session found and read **GEPD's actual source** (`C:\Users\james\Games\Emulators\Nintendo 64\1964_GEPD_Edition\1964\source.tar.xz` → `MouseInjectorPlugin/games/goldeneye.c`, extracted copy at `/c/Users/james/AppData/Local/Temp/gepd-src/`) and mirrored its model exactly. **User verdict: "mechanically it works... the aim mode works how we'd want."** Committed as `ef49d9e6` on `fix/d194-mouse-dt-decouple` (branch is up to date with main; PR #75/#76 already merged in). + +**The model (all in `port/src/input.c`, `aimGepdCompute()` ~line 1377):** mouse delta moves a crosshair POSITION accumulator (`s_gepdCrossX/Y`, clamped ±`GEPD_CROSSHAIR_LIMIT`=5.16); each tick it writes `crosshair_x/y_pos` + `gun_azimuth_angle/turning` (GEPD formulas, failsafe weapon offsets 0.15/0, RATIOFACTOR=1 for our 4:3, `GEPD_BASE_FOV`=90) and edge-scrolls the camera only past 72% toward the screen edge (`(ratio-0.72)*475*dt*(fov/90)`). **No look stick is emitted while aiming.** On aim release we stop writing and the game's own damping eases crosshair+arm back to centre; every non-aim tick adopts `crosshair_x/y_pos` so re-entry starts where the game left it (GEPD does the same). + +**The key correction this session (cost a broken build):** GEPD patches **nothing** in bondview2's damped crosshair update (`caclulate_gun_crosshair_position_rotation`, gunfire.c:4819) — its per-frame overwrite simply *wins* over the damping. The first implementation guarded that function off via `portAimOverrideActive()` → crosshair froze at centre, because the visible HUD crosshair + aim ray are drawn from `crosshair_angle` (gunDrawSight gunfire.c:6395; get_bullet_angle :4932) and the arm offset from `field_FFC` (gunUpdateAndFire ~gunfire.c:540-547, scaled by weapon stats PlayX/PlayY) — **both derived only inside that function**. Guard removed entirely; `bondview2.c` now carries only an explanatory comment. **There is NO permanent game-code change** — the previously-approved bondview2 exception was never needed. (findings.md §F D194 still describes the old attempts — update it this session.) + +**Field mapping verified:** GEPD's N64 RAM offsets (crosshair 0x9F0/0x9F4, gun 0xA04/0xA08, cam 0x148/0x158, aimflag 0x124) differ from our 64-bit struct by a **constant 0xBE0** = pointer-width expansion between vv_theta (0x148, matches exactly) and the crosshair block. Field *names* are correct; do not "fix" them toward GEPD's numeric offsets. + +### Remaining work, in user-specified priority order + +**① Crosshair/arm "spazz" glitch (TOP PRIORITY).** User: crosshair "glitches or spazzes out and moves around a bunch, so does the positioning and Bond's hand/gun." Ranked suspects: + - **(a) `vv_theta` [0,360) wrap in `aimGepdCompute`** — if the game holds a *negative* `vv_theta` (turning left), the first edge-scroll tick snaps it +360. sin/cos consumers see nothing, but anything doing raw deltas (e.g. `speedtheta`, "computed from vv_theta") gets a one-tick 360° spike → HONEY feeds `turn_x = speedtheta*0.3` into the crosshair (bondview2.c ~6157) → visible slam. GEPD just does `camx += ...` with no wrap. **Fix: delete the two wrap lines.** + - **(b) Tick ordering vs auto-aim/view-speed turn terms.** HONEY's caclulate_ input is NOT the stick — it's `autoaimx/autoaimy` (target lock) or `speedtheta*0.3`/`-speedverta*0.1`. Those get *added* to `crosshair_x_pos` every tick on top of our overwrite; if `inputComputePad` runs BEFORE `bondview2ProcessInput` in a tick, the derived `crosshair_angle` shown that frame includes damp-shrunk value + turn term → one-frame tugs, worst near enemies (auto-aim snap) and while edge-scrolling. Check call order; GEPD's plugin writes *after* game code each frame — if ours is before, consider deferring the write to a post-update hook. + - **(c) 2px/poll deadband stick-slip** (`AIM_ABS_DEAD_PX`) at low mouse speeds — whole-poll drop makes the crosshair crawl in steps; GEPD has no deadband (emulator deltas are clean). Consider subtractive deadband or dropping to 1px. + - **(d) `s_centreClearTicks` spring-clear nudge** (2-tick ±61 pitch stick on aim entry, docentreupdown) — with caclulate_ running again it feeds `turn_y` → small crosshair jump at aim entry. GEPD doesn't do this; candidate for removal. + - **Diagnosis first:** repro with `GE_INPUTLOG=1`, capture the log (stderr → file, see below), look for 360° jumps in `cam=(...)` and oscillation in `cross=(...)` in the `gepdaim` lines. Repro into a level without menu navigation: `./build-pc/ge007.x86_64.exe -level_09` (BUNKER1) or `-level_33` (Dam); drive input with `build-pc/aiminject.exe [dx dy steps holdms]` (RMB + relative moves, finds the "GoldenEye" window). + +**② Aim-mode FPS drop.** User saw ≤10 FPS (DisplayFPS overlay) in the last playtest session; hip-fire/menu fine. **First control: that session had `GE_INPUTLOG=1` — retest with it OFF before anything else** (per-tick `sysLogPrintf` while aiming). Then run `tools_pc/perf.ps1` (ETW/xperf, needs elevated PowerShell): baseline `perf.ps1 -level_33 -Seconds 30` without aiming, then a second capture while holding RMB + moving the mouse (user or aiminject), diff `cswitch_thread.csv`/`profile_detail.csv`. Caveat from its header: our exe's DWARF symbols don't resolve in WPA — hot frames show as raw module; symbolicate sample addresses with `addr2line -e build-pc/ge007.x86_64.exe -f -C ` (image base 0x140000000). Suspects if CPU-bound: auto-aim scan while RMB held (verify it's actually NEW cost vs legacy aim, which also held RMB), viewmodel skinning, the edge-scroll camera writes. If NOT CPU-bound: render-path stall (crosshair/decals/draw calls) — instrument frame time in `port/fast3d/gfx_pc.cpp`. + +**③ Sensitivity tuning (LAST, user will co-tune live).** Knob: `Input.GepdSens` (default 20, range 1–80) → `sens = gepdSens/2920` per window-px. GEPD's own formula for reference: `crosshairpos += delta/10 * (SENS/292) * accel` with their basefov=60 override; ours is adapted to native 90° FOV + no /10 chunking, so the numbers are NOT directly transferable — tune by ear/eye against "normal aiming" feel (C-stick speed levels `(stick-60)/10`). Also tunable: `GEPD_SCROLL_SPEED` (475), `GEPD_EDGE_THRESHOLD` (0.72) if edge-scroll feel is off; per-weapon `offsetpos[32]` table from goldeneye.c if the arm pose looks wrong for specific weapons (we use failsafe 0.15/0). + +### Environment / procedure notes (this session's hard-won ones) + +- **Build:** `export PATH="/c/msys64/mingw64/bin:$PATH" && ./build-pc.sh ntsc-final` from repo root (~5s cached). The manual `build-pc/link.bat` path also works but needs its `set PATH=C:\msys64\mingw64\bin;%PATH%` line (cc1.exe dies 0xC0000135 without it) and Windows-style TMPDIR. **Kill any running `ge007*` process before linking** (exe lock). +- **Run for playtest:** from repo root, `powershell -NoProfile -Command "$env:GE_INPUTLOG='1'; Start-Process -FilePath '.\build-pc\ge007.x86_64.exe' -WorkingDirectory (Get-Location) -RedirectStandardOutput 'd194_gepd.log' -RedirectStandardError 'd194_gepd.err'"` — **GE_INPUTLOG lines go to stderr** (`d194_gepd.err`), stdout stays empty. ROM at `./data/ge007.ntsc-final.z64`, ini at `./data/ge007.ini` (user's live values: DisplayFPS=1, 1152x864). +- **clang strictness:** game files build with gcc's leniency; clang rejects implicit decls/int-conversions. `struct player *p` not `Player *p`. Forward-declare statics before use. +- GEPD mouse settings live in the emulator's `plugin/mouseinjector.ini` (numeric, 10 values × 4 players; couldn't fully decode — first value 87 doesn't fit the CONFIG enum). We use GEPD defaults + our own knob instead. + +**Repo state at session end:** `fix/d194-mouse-dt-decouple` @ `ef49d9e6`, clean tree, up to date with main. No running game process (killed before close-out). **Untracked `d194_gepd.err` in repo root is kept on purpose: it holds the `gepdaim` per-tick lines from the user's "mostly feels good but spazzes" playtest of the final build — mine first evidence for ① (look for 360° jumps in `cam=` and oscillation in `cross=`). Next session: preflight per usual, then start at ① above — suspect (a) is a two-line fix worth doing before the log-driven diagnosis. + +--- + +## M-121 (2026-09-13) — PR #75 (D250 getenv fix) + PR #76 (D222/D218/D249 FOV/culling/drawdistance) both MERGED, user-confirmed across resolutions; RMB aim-mode still broken, two more attempts failed, session ended on usage limit mid-investigation + +**PR #75 and PR #76 both merged to main this session, both user-confirmed working.** D250 (getenv caching fix) confirmed clean at every resolution tested, 640x480 through 4K — the initial "still bad at 1440p+" report was a stale-build false alarm, corrected in the docs. D222 (FOV-scale cull-plane fix) + D218 (Video.DrawDistance) + D249 (Video.LodDistance) landed together, then needed **two live retuning passes** before the user was satisfied: (1) a real regression found and fixed live — D222's `c_lodscalez` widening also fed `propobj.c`'s character/prop fog-visibility-fade cutoff uncompensated, making guards fade *sooner* at wide FOV; composed `portDrawDistanceMultiplier()` into those call sites to fix it. (2) The `DrawDistanceAutoFov` coupling needed doubling twice live (1x -> 2x -> 4x `FovScale`, clamp ceiling 2.5x -> 4.0x -> 6.0x) before the Dam tunnel's blue fog artifact and guard draw-distance were acceptable. **User's own final verdict: "good for now."** Repo is clean on `main` after both merges. + +**RMB aim-mode (D194 continuation): two more attempts this session, both did not land, session ended mid-plan on the weekly usage limit.** + +- **Attempt 1 (small, safe): raised `AIM_MOVE_THRESH` 0.3->2.5px and lowered `Input.MouseAimSpeed` default 16->14 (matching the user's live ini, which had drifted to 50).** User's verdict: **"didn't actually fix anything"** — confirms the core problem isn't a magnitude/gain issue, it's the shape of the response. +- **Real root cause found via code reading (still valid, not invalidated by what follows):** `bondviewProcessInput(s8 stick_x, s8 stick_y, ...)` in `src/game/bondview2.c` takes a **signed 8-bit stick** — the smallest representable nonzero aim-turn value is a hard jump to 10% speed (stick=61; `(stick-60)/10` is exactly 0 at stick<=60). No threshold/curve tuning on the port's synthesis side can produce a smooth ramp through an integer that can only be 60 or >=61. Confirmed via `pd_port` (`C:\Users\james\Source\Repos\pd_port`) reference: PD's own mouse-look (`src/game/player.c:3669`, `src/game/bondeyespy.c:945`) never synthesizes an N64 stick at all -- it's `theta += mdx * scale`, a continuous float angle accumulator, no floor, no int8 quantization anywhere. +- **User also reported a second, more specific symptom mid-investigation: aim resets to center the instant mouse movement pauses (even while still holding RMB), breaking precision tasks (shoot-the-lock, watch-laser-cuts-metal-in-train puzzles).** Traced `bondviewCurrentPlayerUpdateSpeedTheta`/`speedVertaUp`/`Down` (bondview2.c) in detail: confirmed this is a smoothed rate-based decel model (`g_CurrentPlayer->speedtheta` eases toward 0 over several ticks when input stops, does NOT hard-reset) -- so a literal snap-to-center was not found in that specific mechanism. Root cause of the reset symptom specifically was **not conclusively identified** before moving to the rewrite. +- **Attempt 2 (bigger, PD-style, approved by user before starting): bypassed the s8-stick synthesis entirely for aim-mode.** `port/src/input.c` computed a continuous -1..1 turn/vert speed (`inputGetContinuousAimSpeed()`, new function + header decl) instead of synthesizing `sx`/`sy`; `src/game/bondview2.c`'s aim-mode block (`#ifdef PORT`) read it directly, bypassing the `(stick-60)/10` conversion but leaving all downstream `speedtheta`/`speedverta` easing untouched. Removed the now-dead `Input.AimBand`/`Input.MouseAimCurve` knobs. **Compiled clean (verified both PORT and N64 `#ifdef` brace balance carefully), crash-free in a headless sanity check -- but broke live: "somethings broken... can't aim at all... it locks my input completely with the mouse."** Root cause of THAT breakage was not identified (no repro available headlessly; ran out of session before a careful live-debug pass). **Fully reverted** (`git checkout -- src/game/bondview2.c port/src/input.c port/include/input.h` back to the `db6eba2b` merge commit) — repo confirmed clean, PR #62's mouse work is back to its pre-session (working, if imperfectly-tuned) state. Live ini's `MouseAimSpeed` also manually restored 14->16 to match the reverted code default. + +**Best-guess candidates for what broke Attempt 2, NOT verified, next session should check these first:** (a) thread-safety -- `aimContinuousTurnSpeed`/`VertSpeed` were plain `static float`s in `input.c`, read from `bondview2.c` with no synchronization, and this port has separate scheduler/game/input threads (D24/D134 territory); (b) `bondviewProcessInput`/`MoveBond` may run multiple times per rendered frame during multi-tick catch-up (per D193's earlier finding that `g_ClockTimer` can exceed 1), so the continuous value could have been consumed repeatedly per single mouse sample in a compounding way neither of us anticipated. + +**Proposed next step (discussed with the user, not yet started -- session ended before implementation):** a safer, lower-risk redesign that stays **entirely inside `port/src/input.c`**, never touching `bondview2.c` at all. Instead of deriving the synthetic `sx`/`sy` fresh from only the current poll's raw delta, maintain a smoothed/persistent stick value (exponential filter on the *output*) that ramps toward a target implied by recent mouse speed and decays gradually on release, rather than snapping instantly in either direction. This softens both the floor-crossing (builds up over a few polls) and the release/reset behavior (decays instead of vanishing), while keeping the change confined to one already-well-understood port file -- easy to revert, easy to reason about, no `#ifdef PORT` game-logic surgery. **Add a temporary debug log (`GE_INPUTLOG`-gated) that prints the smoothed value every poll, so it can be sanity-checked from a log BEFORE handing back to the user for a live test** -- the process this session was explicitly asked for and didn't happen before Attempt 2. + +**Repo state at session end:** clean, on `fix/d194-mouse-dt-decouple` (still holds PR #62's D194(b)/D238/natural-pitch work, unmerged, mergeable, behind main by the two PRs merged this session -- rebase before resuming). No uncommitted changes. No running game process. + +--- + +## M-120 (2026-09-13) — D250 ROOT-CAUSED AND FIXED (uncached getenv() ~50% of render-thread CPU time); PR #75 open; PR #62 aim-mode still needs work; new tools_pc/perf.ps1 + +**D250 resolved this session — the fps drop was `getenv()`.** Set up a real profiler (`tools_pc/perf.ps1`, new — wraps `xperf` CPU-sampling + context-switch tracing, sister script to `debug.ps1`) since ad-hoc timers had ruled out `gfx_run`/`lvlRender` without finding the cost. A live WPR/xperf trace on Dam with Microsoft's public symbols resolved (`-Symbols`) found the dominant render thread spending only **5.2%** of its CPU time in the game's own code — **43% in `msvcrt.dll`**, and `getenv()`/`_getenv_helper_nolock` alone at **~50% of the thread's total CPU time**. Root cause: `port/fast3d/gfx_pc.cpp`'s `import_texture()` (every texture bind) and several per-triangle/per-`G_SETCOMBINE` debug-probe checks called `getenv()` **uncached** on every call, unlike the safe cached pattern used everywhere else in this codebase — tens of thousands of locked, locale-aware Windows CRT environment lookups per second on a texture-heavy scene. **Fixed:** cached every site in `gfx_pc.cpp`/`gfx_opengl.cpp`. **Verified:** the exact idle-Dam test that was pinned at 45-50fps now holds a rock-steady 60-61fps, zero dips — and the user confirmed live at 640×480 it "seems fine" now. This also retroactively explains the earlier session's MSAA/aniso/FOV/resolution/vsync A/B pass all showing "no change" — the getenv() cost was a large per-call constant swamping any real, smaller GPU-side signal at every setting tried. **PR #75 pushed** (`fix/d250-frame-pacing-sleep-units`, now titled around the getenv fix — also carries the earlier sysSleep unit-conversion fix and the `GE_D250` `lvlRender` probe from this same investigation), CI running at session-end, not yet merged. + +**"Still runs badly at 1440p+" turned out to be a stale-build false alarm** — user re-tested 1440p/4K on the actual getenv-fix build and confirmed it holds up fine there too. **D250 is fully resolved, all resolutions tested clean, no follow-up needed.** One gotcha hit setting up `perf.ps1`: its first version was missing `debug.ps1`'s mingw64-bin-on-PATH fix and failed with a DLL load error from a plain elevated shell — fixed, same PATH-prepend logic now in both scripts. + +**PR #62 (mouse feel) status unchanged from earlier this session** — hipfire/primary look confirmed good by the user; aim-mode (RMB/Shift) still too sensitive, `AIM_STICK_MIN=61` hard-floor hypothesis recorded in `findings.md` D194, not yet fixed/reverified. Deprioritized this session in favor of the performance investigation once it became clear perf was confounding the aim-mode feel-check anyway. + +--- + +## M-120 EARLIER (2026-09-13) — PR #62 rebased onto main (picks up D248); user playtest: hipfire good, aim-mode still too sensitive; performance diagnosis (D250) queued next + +**PR #73 merged, `fix/d194-mouse-dt-decouple` (PR #62) rebased.** #62 was 15 commits behind `main`, missing D248's 60fps fix among others — merged `main` in (two doc-only conflicts in `findings.md`/`findings-index.csv`, resolved by keeping the newer main-side text + regenerating the CSV), rebuilt clean (`ninja -j1`), pushed. A headless `verify.sh bunker1` sanity check afterward reported `NO-FRAMES (pixcount 0)`, but the script's own capture-directory (`mktemp`/`/tmp`) plumbing looks broken in this shell environment (its `run.log` write itself failed with a path error) — looks like tooling, not a real regression; not chased further, worth a look next session. + +**User played PR #62 live. Verdict: hipfire/primary look is GOOD, aim-mode (RMB/Shift) is still too sensitive and unusable for precision aiming.** Updated D194's status cell with the detail (`docs/dev/findings.md`). Static re-read of `port/src/input.c`'s `aimHeld` branch found a plausible concrete cause the M-107 curve fix didn't address: `AIM_STICK_MIN=61` is a hard floor the stick snaps to the instant `|aimEdx| >= AIM_MOVE_THRESH` (0.3 px/poll) — the `aimCurveGamma` response curve only shapes the range *above* that floor, so tiny mouse nudges still jump straight to 10% of max aim-turn speed with no near-zero ramp, unlike the hipfire path (fully proportional, no floor) the user says feels right. **Not build/runtime-verified yet** — a hypothesis from reading the code, not a confirmed fix. **PR #62 stays held, unmerged** — needs another aim-mode iteration + re-playtest before it can land. + +**User also reports the port is now performance-limited — ~45fps at 720p on a high-end PC — which makes it hard to judge feel further.** This is the user-facing surface of **D250** (filed M-119, tied to D248 exposing real per-frame cost that used to be invisible while the port silently ran at half rate). **Same session: diagnosed partially, real bottleneck not caught yet.** Ruled out: build flags (`-O2 RelWithDebInfo` confirmed the actual default) and idle-load — `GE_D193=1` on bunker1 and streets both idle at a healthy 55-60fps in this dev box, well under budget, not reproducing the user's 45fps. So the real cost is very likely gameplay-load-dependent (AI/combat/particles active, not an empty idle scene) or resolution/GPU-fill-rate-bound in a way idle testing can't exercise — this session had no way to drive real keyboard/mouse input into the game headlessly to generate a loaded scene. Docs-only PR **#74** (`docs/d250-perf-diagnosis`, off `main`) carries the write-up. **Same session continued, live with the user driving the game on Dam.** PR #74 merged (docs-only, uncontroversial). Confirmed live: `sim` stays healthy 59-67/s, `render` sags to 45-50/s, `frame rendered in Nus` (`gfx_run` cost) stays 6-10ms — comfortably under budget. One-at-a-time A/B via the F10 overlay **ruled out MSAA, anisotropy, FOV, and resolution** (1280×960 fullscreen vs 640×480 windowed — zero change) **and VSync** (render never exceeds ~60 even fully uncapped, and the bad numbers didn't move) — the cost is resolution/GPU-setting-independent. **Found and fixed a real bug in passing, but confirmed NOT the active cause here:** `sync_framerate_with_timer()` (`port/fast3d/gfx_sdl2.cpp`) passes a 100ns-unit value straight into `sysSleep()` (expects microseconds) — a genuine 10x oversleep, but only on the `target_fps`-gated path, which was inactive in the user's `FpsCap=0`/`VSync=0` test config. Fixed anyway (correctness). **Added `GE_D250`** (`src/boss.c`, wraps `lvlRender()`) to check DL-building cost separately from `gfx_run` — also cheap (~0.5-1.5ms), also not it. **So: two most likely CPU call sites both ruled out, ~10-15ms/frame still unaccounted for.** Leading remaining suspect: the emulated N64 thread-handoff/scheduler round-trip (`gesched.c`/`sched.c`) — real OS thread wake/context-switch latency standing in for what was free hardware handoff on N64. **Next: needs a real profiler** (Visual Studio's sampling profiler, or WPR) attached to `ge007.x86_64.exe` during a live bad-fps moment — ad-hoc printf-timers have now ruled out the obvious spots without finding the cost; more of the same probe-and-guess approach has diminishing returns.

It did not — found and fixed a real, previously-undiscovered bug that had been halving presentation/tick rate to 30fps since the port's inception.** Root cause: `src/sched.c` `osScAddClient()` stashes a per-client "every retrace vs. every other retrace" flag by writing into the *next array slot's* `.next` field (`c[1].next = next`) instead of a real struct member — `gfxClient` gets `NULL` (60Hz), the audio client gets a nonzero sentinel (30Hz, its correct rate). `__scHandleRetrace` reads that flag back via a hardcoded `*((s32*)client + 2)` byte offset that only lands on the right memory when `sizeof(OSScClient)` is 8 bytes (32-bit pointers, true on N64). On this 64-bit port `sizeof(OSScClient)` is 16 bytes, so the same offset instead reads into the middle of `client->msgQ` (always non-NULL) — the gfx client's flag reads as permanently set, and it silently falls onto the audio client's 30Hz path. Same pointer-width-growth bug class as D122/D126/D132/D209, just in the scheduler. **Fix:** `#ifdef PORT` reads `client[1].next == 0` (indexes the struct, scales correctly with pointer width) instead of the hardcoded offset; N64 line kept verbatim under `#else`. **Verified live:** `Video.DisplayFPS=1` overlay read a rock-stable "30 FPS" pre-fix and "60 FPS" post-fix on `-level_09` (BUNKER1), same build/scene, `GE_PCDUMP` screenshots both ways.

Restored the envmap UV generation from the reference PD port, gated on `G_TEXTURE_GEN`. **User-verified:** console glass and gold/silver guns are reflective again, not flat black.

No code change. +- **D246 (left/right edge strips) narrowed, still OPEN.** `GE_PCDUMP` captures show clean edge columns in the native render, ruling out an RDP/game-DL bug — the defect must be introduced in the SDL window presentation path, which headless capture doesn't exercise. Needs the user's window size / `Video.MSAA` setting to chase further. +- **D245 (water seam) REOPENED.** The `allowShift=FALSE→TRUE` fix (mechanistically sound-looking, confirmed via a `GE_D227V` static trace) did **not** fix the live symptom — user reports the water still flips between two patterns and still tracks view angle, unlike the sky (same underlying mechanism, no longer broken there). The static single-frame/single-angle trace this session used was evidently insufficient evidence; needs a fresh investigation with a live or multi-frame-rotating capture, not a repeat of the same approach. Don't re-apply the same reasoning without new evidence. + +**Process note, worth repeating for future sessions:** `verify.sh` and any `taskkill //IM ge007.x86_64.exe` kill whatever game instance is currently running — including one the user has open themselves for manual testing. Hit this mid-session: ran `verify.sh` while the user was actively testing a fix, killing their window without warning. **Always ask before running verify.sh/launching/killing the exe if there's any chance the user has it open.** When the user is actively testing, do documentation-only work and wait for their report rather than re-launching to check yourself. + +**Not done this session:** a full `verify.sh sweep` after D228 (only a headless single-level check + user's own live playtest); D246's live-window follow-up. + +## M-116 (2026-09-12) — D229 (green/pulsating IsWater water) ROOT-CAUSED AND FIXED (port-layer); next: D195 + +**D229 closed out this session.** The earlier "one texunit resolves blue and the other green" framing was wrong on mechanism, right on symptom. The water image (`skywaterimages[2]` = texnum 1509 `IMAGE_WATER_BLUE`) is **ZLIB+CI8**: the texture pool holds raw 8-bit palette indices (dumped pool block: 1400 bytes, every byte ≤ 23 — the 24-colour blue palette's index range; full mipmap chain + row padding). `texSelect` loads it with `gDPSetTextureImage(CI, 16b)` + `gDPLoadBlock` (the 16b is only fast3d's 4KB-per-block convention: 700 × 2 = 1400 bytes of 8-bit data). On N64 GE's custom RSP ucode expands indices→RGBA16 in TMEM at load time, so `sub_GAME_7F09343C` can re-declare TMEM slot 0 as RGBA/16b and sample blue. fast3d had no expansion: `import_texture_rgba16` read index byte-pairs as 16-bit texels — g = 2·idx mod 32 dominates, r/b ≤ 2 → green mottle; the "pulsating" was just the pre-existing `sinf()`-driven PRIM_LOD_FRAC cross-fade between the two mis-decoded tiles. (The N64 side is provably expanded: no shade of a G-dominant texel can multiply into B>G output.) **Fix (port-layer only, `port/fast3d/gfx_pc.cpp`):** `texture_to_load.fmt` was previously dropped — now recorded into `LoadedTexture.src_fmt` by `gfx_dp_load_block`/`gfx_dp_load_tile`; in `import_texture`, an RGBA/16b tile whose slot's last load came from a CI source routes through `import_texture_ci8` (palette expansion via `rdp.palette`) — the port equivalent of the ucode's expand-at-load. Fires only on the genuine format disagreement; real RGBA16 textures untouched. **Verified:** Frigate `-level_26` live run, water renders blue, user confirms "looks better". A GE_D229-gated confirm log (one-shot) remains in import_texture; the ad-hoc SetTexImage/LoadBlock/LoadTile probes were removed. **Still owed before the row is fully closed:** standard verification ritual — `verify.sh sweep` + by-eye on Surface 2 (the other IsWater level). Docs updated: findings.md D229 row + §H resolution, index csv regenerated (D229 → FIXED), ROADMAP Task 1 item 1(a) struck through. + +**New user bug reports filed same session (documented only, not investigated): D245** IsWater water shows two competing patterns + a view-tracking seam — "looks almost exactly like skybox"; strong lead is the documented `allowShift=FALSE` s16-tc-overflow tolerance in `sky.c` `skyPortBeginFan` (D227's mechanism, made visible by the D229 fix); **D246** tiny raw-pixel strips at the left/right screen edges ("overscan") — suspect present/scale blit rounding; **D247** black bars top/bottom — possibly intended 4:3 letterbox pending the parked WIDESCREEN-FOV-PLAN, needs the user's window aspect to tell. All three are in findings.md §F + index. + +**Next (ROADMAP-1.0 Task 1):** item 1(b) **D195 Control transparency** — uninvestigated, needs a capture first. Then 1(c) D228 white NPC-weapon patches. Unchanged elsewhere: PR #56 still blocked on filing the fast-alt-tab audio-restore-race Dxx (index topped at D244); PR #62 held for the combined D194(a)+SOLITAIRE+D238 pass; bunker1 golden stale until re-baselined. + +## M-113 (2026-09-12) — D219 (purple explosions) FIXED: genuine byte-order bug in the runtime texture decompressor (next session starts here) + +**D219 root-caused and fixed this session.** A dispatched subagent (M-112) hit a dead end — its diagnostic probes never fired because they filtered on the GBI tile's declared width (16) instead of the bitstream's real decoded width (14), and it also hit an environment issue getting stdout from the game exe. Picked it back up interactively: fixed both (the real width is 14×14; the "no stdout" issue was `timeout` stripping the child's env in that shell — a plain background `&` + `taskkill //IM` gets it fine here) and traced the actual bug to `src/game/image.c`'s runtime texture decompressor (`texReadUncompressed`, `texChannelsToPixels`, `texBuildLookup`, `texInflateLookup`, `texInflateLookupFromBuffer` — all ground-truth decomp, never modified before now). These reconstruct each wide (>1 byte/pixel) pixel as a shifted-OR integer and commit it with a **native machine store** (`dst16[x] = value`) — correct on N64 (native store = big-endian, what `port/fast3d/gfx_pc.cpp import_texture_rgba16` expects), silently byte-reversed on this little-endian host. Only `IMAGE_FIRE_0..14` hit it because they're one of the only assets that are both genuinely 16-bit-per-pixel (RGBA16) *and* runtime-decompressed (static C-array textures are already normalized by D71's `gfx_tex_normalize_source`; every other runtime-decoded format in the game is single-byte/no-endian). Fix: `PORT_PIXEL16`/`PORT_PIXEL32` macros (`__builtin_bswap16`/`32` under `#ifdef PORT`, identity under `#else`) wrapped around every wide-pixel store in those five functions — narrow, mechanical, N64 build byte-for-byte unaffected. **Verified:** `GE_TEXDUMP` PPM captures of all 15 fire textures flipped from B-dominant (pre-fix, matches M-111's finding) to R-dominant/warm (post-fix); a 10x-upscaled render and a 6-frame animation strip show a clean fire-sprite look (bright core → orange → red/ash), no purple/blue. A 12-texture montage of unrelated Dam world textures confirmed no regression. `-level_09`/`-level_33` both boot and render crash-free post-fix. Full write-up: `docs/dev/findings.md` D219 row, "M-113" paragraph; new porting-notes.md entry under §C (native-store byte-order bugs in runtime-decoded multi-byte pixel formats). **Not yet done, next session:** a full `verify.sh sweep` (21 levels) and a live human playtest of a real (non-scripted) firefight/explosion to close the row for good — everything here is scripted-repro + texdump evidence, strong but not a human eyeball on the actual game. Working tree left **uncommitted** (`src/game/image.c`, `docs/dev/findings.md`, `docs/porting-notes.md`) for review before landing. + +## M-108 (2026-09-12) — D194(b) played, held (not merged); D160 finally live-traced, real root cause found and split to D243; D240/D241/D242 filed + +**Environment gotcha, hit hard this session, fix it first:** this box's Bash tool is Git Bash, not true MSYS2 — `MSYSTEM=MINGW64` is set but `/mingw64` doesn't resolve. Every build/run command this session needed `export PATH="/c/msys64/mingw64/bin:/c/msys64/usr/bin:$PATH"` prepended first. Also: **`ninja -j` (parallel) failed every time** with `Cannot create temporary file in C:\Windows\: Permission denied` from gcc, even though `TMP`/`TEMP` were correctly set and writable — looked like an env-propagation race under `-j`. **`ninja -j1` (single-threaded) built clean every time, no code changes needed.** Use `-j1` for this project on this box until someone roots out the real cause. Also: the exe resolves save/config paths as `data\` **relative to CWD** (`port/src/system.c:212,244`) — launch it with CWD at the repo root (or wherever `data/` is a direct child), never from inside `data/` itself, or saves/config silently fail into a nonexistent `data\data\` path with no crash, just silent write errors in the log. + +**D194(b) played (PR #62, `fix/d194-mouse-dt-decouple`): real improvement, not enough — PR stays unmerged.** User's verdict: "better by default but still feels bad. vertical input is different than horizontal, right mouse aiming is still way too sensitive." Both residual complaints match already-catalogued, not-yet-implemented parts of D194 exactly — nothing new to investigate: RMB over-sensitivity = **D194(a)** (the aim-mode response curve, separate `[61,80]` clamp system, unimplemented); vertical/horizontal asymmetry = the **`CONTROLLER_CONFIG_HONEY` vs `SOLITAIRE`/`GOODNIGHT` controldef** finding from M-87 (hipfire pitch is digital-only under HONEY, forced by the port; SOLITAIRE frees the whole analog stick for continuous pitch+yaw, unmodified GE control scheme). **User's explicit call: hold #62, do D194(a) + the controldef switch + D238 together as one pass, then re-playtest before merging anything.** PR #62's CI is green/CLEAN and mergeable whenever that full pass lands and feels right — it doesn't need rework itself, it's just incomplete on its own. + +**D148/D160/D173 cutscene investigation: finally got a live trace this session (`GE_D160=1`, Dam `-level_33`, two debug-loads + one fresh-save normal playthrough) — real progress, not just re-confirmed dead ends.** Big correction: **D160's old premise ("cutscene never plays, cuts straight to mission complete") is REFUTED on the current build** — the trace shows the AI trigger firing and all 3 scripted `camera_switch` calls executing every time. The cutscene runs; it renders corrupted. New finding **D243** filed with the real mechanism: a `D146` fast3d guard burst (freed/uninitialized-memory byte pattern `0xfafbfbfcfcfbfdfc`, same 4 addresses repeating) fires right in the camera-cut window — a stale display-list-memory read, likely a render-pipeline race (two debug-load runs showed the AI-list's camera_switch calls landing in a *different order* relative to `bossReturnTitleStage` between runs, and the corruption appeared in one run but not the other — nondeterministic, i.e. a real race, not a fixed logic bug). **User-confirmed the camera-glitch reproduces on a real fresh-save playthrough too**, not just the debug-load harness, so it's a genuine bug, not a `-level_N` testing artifact. A *second* symptom seen only on the debug-loaded runs (no report screen, straight to file-select, save not landing) did **not** reproduce on the fresh-save run — that one is most likely a `-level_N` debug-boot artifact (same class as D190) and was deliberately NOT filed as its own bug; don't re-investigate it as real without a fresh-save repro. **Next step for D243:** an env-gated probe on whatever frees/recycles the segment or double-buffer slot backing the outgoing camera shot's geometry during the `ai_17` window, cross-referenced against the 4 repeating fault addresses (session logs `data/playtest_d160.log` + `_run2.log`, not committed — regenerate by repeating this session's steps if needed). + +**D240/D241/D242 filed** (subagent, docs-only, `docs/dev/findings.md`): D240 gunshot-SFX-timing (LOW-MED confidence, could be a stale pre-D209 report or a real residual in the same timing-keystone family); D241 PP7/AK47-silent-not-Klobb (**HIGH confidence this is D207 reproduced** — fold into D207 rather than tracking separately, the repro D207's own M-77b session couldn't get); D242 death-sequence-needs-LMB-click (**HIGH confidence NOT a port bug** — the 3-angle auto-death-camera and its no-input auto-transition exist unmodified in the decomp; LMB is GE's own original Z_TRIG skip button; still needs a playtest confirming the *automatic* no-click path actually completes promptly on PC). + +**D233 visually confirmed fixed this session** — `-level_26` (Frigate; note the *correct* level id, `LEVELID_FRIGATE=26` per `bondconstants.h`, not the `-level_02` guess in the old finding text) doorway/corridor geometry no longer flickers/vanishes near room boundaries.

PR **#62** (D194b) still open and unmerged, untouched this session beyond the playtest. No `src/`/`port/` changes this session — investigation and docs only.

Design: + `Game.NoHitFlash` int config (declared + registered in `port/src/video.c` + next to the other route-(b) vars) + a route-(b) gate in + `currentPlayerSetFadeColour` (`src/game/bondview2.c` ~4236): when the flag + is set, zero any non-black RGB. Rationale (verified by exhaustive caller + grep): EVERY fade routes through this one function, and the only non-black + callers are the two damage paths — the per-frame `g_DamageTypes` envelope + in `bondviewPlayerTickDamageAndHealth` (all 8 rows are WHITE 0xFF,0xFF, + 0xFF with an alpha envelope scaled by remaining health) and the red + 150,0,0 death overlay (`bondview2.c:9121`) — every other caller passes + (0,0,0). So zeroing RGB kills exactly the hit flash; blackouts, the colour + screen and the death fade are untouched. Default 0 = original. + **Verification state (frame A/B via `GE_PCDUMP=1-900 -level_09`, BUNKER1, + 721 frames each):** (a) determinism CONFIRMED — two default runs are + near-identical (max Δ 0.41 mean-luminance units, most <0.01), so A/B + methodology is valid; (b) default vs gate-on: the gate-on run is uniformly + ~24 luminance units BRIGHTER at frames 28–45 (no colour cast: A=(57,53, + 52) vs B=(81,78,77)), reconverging by ~frame 460, plus a tiny +0.15 blip + in the default run at frames 473–494 (direction matches a small flash). + **Anomaly:** white→black zeroing should make gate-on DARKER, not brighter; + the simple overlay model out=S(1-a)+rgb·a is refuted (fitting requires + S>255).

Root-caused + with an instrumented trace build (temp `git worktree` at `../gh-fullhist-d223`, + `GE_D223_TRACE` env-gated logs in `port/src/input.c` + `bondview2.c` + + `gun.c`, all reverted before landing): the wheel-down pulse staggered the + synthetic "hold A, tap Z" combo across 2 polls (A alone, then A+Z one poll + later). Whenever those land in 2 SEPARATE game ticks (a D117-class + poll/tick-rate race), the "A alone" tick is itself a fresh A edge with no Z + held -> `bondview2.c`'s `weaponForwardOffset` formula reads that as a + genuine cycle-FORWARD request and fires a REAL weapon change before the + correcting backward tick runs. Trace showed literally every wheel-down + after the first one in a session mis-firing forward. **Fix** (`port/src/ + input.c` only): present A+Z together from the first poll instead of + staggering — `weaponForwardOffset` requires Z NOT held, so simultaneous + A+Z is unambiguous (backward only), regardless of tick timing; + `moveData.triggerOn` (real fire) is separately gated off while A is held, + so no accidental-shot risk. **User-verified fixed** via a second + instrumented rebuild (every notch now produces exactly one correct, + symmetric step both directions).

(1) Added the + `GE_NOHITFLASH_TRACE` env-gated `osSyncPrintf` in the gate (pattern: + `getenv`-gated like `GE_D160`, `bondview2.c:4247`), rebuilt (241/241 + green). (2) Ran it headless (`GE_PCDUMP`, `-level_09`, ~3500 frames, + unmanned/no-input) — **zero trace fires**, confirming no damage ever + occurs in this kind of run, so the gate is provably inert here regardless + of setting — the earlier frame-28-45 "brighter" delta cannot be the + hit-flash gate touching a real fade. (3) Re-ran the actual A/B properly: + same binary, only `Game.NoHitFlash` toggled via `data/ge007.ini` (no env + override for it), A0/A1 = two runs with the flag OFF (repeat), B = ON, + each 100 `GE_PCDUMP` frames, diffed with `tools_pc/framediff.py` in both + `--exact` and the project's own default structural/tolerant mode. + **Result: A0 vs A1 (same build, same config, run twice) = 0/100 frames + match** (87% of pixels differ by frame ~73, tolerant mode too) — i.e. the + port is NOT deterministic even by frame ~73 in this scenario. **A0 vs B + (gate off vs on) = 99/100 frames match** (tolerant mode; differences are + ~0.1-0.3% of pixels, an order of magnitude smaller than the A0/A1 same- + build noise floor). **Conclusion: D232's gate causes no detectable visual + effect beyond ordinary run-to-run noise** — the prior session's "gate-on + uniformly ~24 luminance units brighter" read was a false signal from an + under-powered metric (mean luminance, coarse enough to miss/alias massive + per-pixel divergence) colliding with the **already-catalogued, still-OPEN + D117** frame-to-frame nondeterminism (`findings.md` D117: "root-caused; + `GE_DETERM` deferred... determinism NOT achieved"; `framediff.py`'s own + header already documents "two runs of the same build diverge 15-40% of + pixels by frame ~200" — this session's repro (87% by frame ~73) is the + same phenomenon, not a new one). **Lesson for future headless A/B verification + on this port: use `framediff.py`'s per-pixel/structural comparison, not a + single scalar like mean luminance — D117 noise is large enough that a + coarse metric can average it away and look like a false "clean" result OR + (as happened here) get misread as a real signal.** No code fix needed; + D232 stands as **code-verified correct** (exhaustive caller audit, now + also headless-trace-confirmed inert absent real damage) with the human + playtest as the actual merge gate, same as always intended.

Its exports + (`HookRDRAM`) and readme show it writes directly into the emulated + game's RAM rather than going through N64 controller-pad emulation, and + its own FAQ says responsiveness needs mouse polling decoupled from + frame pacing (recommends `NtSetTimerResolution` + disabling vsync). This + independently corroborates the port's own existing D194 diagnosis (part + b: sensitivity couples to frame/poll rate) as the dominant lever — raises + confidence in prioritizing that half of the fix, doesn't change the fix + direction or supply new constants (nothing else was recoverable from a + stripped, hardcoded-per-ROM-title binary). + +## M-102b (2026-09-11) — refreshed `docs/dev/notes/ROADMAP-1.0.md` (v1.0 triage), same style as the docs-triage pass below. + +Rewrote the plan of record: fresh "Where we are now" superseding the stale +M-49/M-87 sections, an acceptance-bar status table, and a full +impact×effort triage of every open `findings-index.csv` row into +Tier 1 (blocks the bar: D77 in-level music, cutscene reliability +D148/D160/D173/D219, D194 mouse feel, D190 Linux crash, D195/D229 visual +correctness) / Tier 2 (D228 AK47 textures, the D222/D218/D220 FOV +break-set, assorted papercuts) / Tier 3 (QoL: HUD scale, rebinding UI, +per-pad tuning) / explicitly-deferred (GE_DETERM test-infra, multiplayer, +region scope — decisions not bugs).

Headline items: + +- **Real bug, same class as the D227/M-98 misfile that cost a session:** + `findings-index.csv`'s generator bucketed **D194 as FIXED** — it's an open + design item — because that row's table structure was broken (2 cells, no + distinct status column, so the generator's fallback keyword search matched + "fixed" somewhere inside 6,500 chars of narrative).

Green/pulsating water is real, pre-existing, filed as D229 (not root-caused). + +**Read `docs/dev/findings.md` §H "D229 — M-101".** + +**Green weapon textures on Frigate/Surface 2: not a bug.** This branch was 2 +commits behind `main`, and those 2 commits were exactly the D217 fixes +(`7278baad` #47 texpool alignment, `f15a12b9` #49 CI cache palette-content +key). Merged main in (`f8822805`); user confirms the gun is good. **Process +point: check branch-vs-main before investigating any D217-family symptom +reported against a feature branch.** + +**Green/pulsating water on IsWater levels: real, pre-existing, D229.** A/B +proven — plain `main` with none of the D227 work shows the same green. +Mechanism partly identified: `sub_GAME_7F09343C` binds tile 0 and tile 1 to the +same TMEM, offsets tile 1, and cross-fades TEXEL0/TEXEL1 by a `sinf()`-driven +`PRIM_LOD_FRAC` — that sine is the pulsing, so one texunit resolves blue and +the other green. Shade path ruled out by measurement. **Not root-caused.** + +**NEXT TASK if picking up D229:** the existing `GE_D172` multitex probe does +not fire here (it filters on `tile1.tmem != tile0.tmem`, equal in this draw) — +widen it. And capture a **sequence** across the sine period: a single frame is +useless, frame 340 reads green on all three builds tested because of where the +sine lands. Then check `skywaterimages[2]`'s real format against the RGBA/16b +that `sub_GAME_7F09343C` re-declares. + +**D227 is deliberately decoupled from D229** — `skyPortBeginFan` now takes +`allowShift` and the water quad passes FALSE, leaving that path byte-identical +to pre-D227. Do not "fix" the water by shifting both tiles: that was tried live +and flattens the cross-fade into constantly-green. + +**bunker1 golden is now badly stale.** `verify.sh bunker1` reports REGRESSION +at `worst_cell` 55.02 on this branch — but plain `main` is **worse at 73.24**. +main's D217 texture fixes moved the pixels; the re-baseline owed since +M-83/M-84 is now overdue and is making the per-patch gate useless. Worth doing +before the next rendering change. + +**User environment note:** their playtests run with **FOV turned up** +(`Video.FovScale`); all headless captures here ran at the ini default of 100. +Green reproduces at 100, so FOV is not required for D229 — but the black bands +at the capture edges are probably the FOV-coupled D218/D222 family, not D229. + +## M-100b (2026-09-11) — D227 FIXED (pending your play-test). Cause was a UNIT ERROR, and it also fixes the "sky scrolls too fast" complaint. + +**Read `docs/dev/findings.md` §H "D227 — M-100b".** M-82 ("D176(a) Defect 1") +read `unk20`/`unk24` as texel counts and baked `tc` as `(S - fold) * 32`. +They are not texels — `skyRender` sets them as `worldpos * 0.1f` and the N64 +path hands them to the RDP coefficient block unscaled, so they are already in +the RDP's native S10.5 1/32-texel units. That stray `* 32` caused **three +symptoms tracked as separate bugs**: D227's seam/starburst (overflow), the +over-tiling, and **M-96's "the N64 sky is nearly static, ours races"** +(`g_SkyCloudOffset` advances 1/32 texel per tick, not 1). Fix is +`tc = (S - fold)` 1:1 with the fold rebased to a whole tile period. + +**Committed:** `3f2b1b4d` (fix), `a0b1de40` + `f1711b59` (the investigation). +Branch `land/d176a-sky-perspective-scroll`, PR #43 still draft. + +**NEXT TASK — play-test.** Both prior D227 "fixes" (M-95, M-98) passed static +headless checks and then failed live, so this is not closed until played. +Check Cradle, Statue and Surface: seam/starburst gone, cloud scale sensible, +and the sky should now scroll ~32x slower (near-static, like the N64). Then +PR #43 can leave draft. + +**Also worth doing:** re-measure the scroll rate against M-98's ~7 px/tick +baseline — it should now be ~0.2 px/tick. Method is in §H "D227 — M-98" +(cross-correlate `GE_PCDUMP=345-355:1` consecutive frames, static camera). + +**New probe:** `GE_D227V=1` dumps per-vertex S/T/w, the chosen shift k, and +the baked tc from `skyPortRenderPoly`. This is what measured the whole thing. + +**Kept deliberately:** the tile-shift safety valve +(`skyPortPickShift`/`skyPortCaptureTile`/`skyPortEmitTileShift`) — the +observed span is 31,513 against an s16's 32,767, only ~4% headroom, so it +degrades gracefully rather than overflowing if a camera exceeds it. Uses the +RDP's own tile `shifts`/`shiftt`, which `port/fast3d` already implements. + +## M-100 (2026-09-11) — D227 ROOT CAUSE FOUND AND PROVEN: `s16` texture-coordinate overflow. Fix designed, not implemented — one decision needs you. + +**Read `docs/dev/findings.md` §H "D227 — M-100" for the full record.** Short +version: the seam is not a crack, not a quantization mismatch, and not +view-dependence. One sky quad spans **~30,000 texels in S and T**, but +`Vtx.tc` is S10.5 in an `s16` = **±1024 texels**, so **7 of its 8 texture +coordinates overflow and wrap to arbitrary values**. M-95 and M-98 each fixed +a real second-order bug; neither could touch this. + +**What unblocked it:** the user's emulator-vs-ours screenshot pair on Surface +(`docs/img/bugs/d227-surface-emulator-ref.png` vs +`d227-surface-starburst-ours.png`). The real symptom is a *radial starburst*, +not a crack — which is a completely different mechanism from what M-94→M-98 +were chasing. + +**M-99's "blocked, needs a human co-session" was wrong.** The defect +reproduces headlessly and statically; M-98 had already captured it (Cradle +frame 350, `d176a-cradle-tower-starburst.png`) but misfiled it as unrelated +"Defect 2". **D227 == D176(a) Defect 2 == the Cradle tower starburst.** +`GE_INPUTSCRIPT` camera-pan is still a dead end, but D227 never needed it. + +**New probe, kept:** `GE_D227V=1` dumps per-vertex S/T/w from +`skyPortRenderPoly` (env-gated, `GE_D176` style). This is what proved it. + +**The fix, and the one open decision.** Subdivide until each sub-primitive's +S/T span is under ~960 texels, with per-sub-primitive folds (folds differing +by multiples of 64 texels are seamless under `GL_REPEAT` at tile width 64). +Two parts are already worked out and written up in the finding: the exact +perspective-correct subdivision math, and where to place the cuts — **S is +linear in w, so cut uniformly in w**; uniform-in-screen is badly wrong (on +this quad's right edge, half the screen distance carries 807 texels and the +other half 26,943). What is NOT decided is the **vertex budget**: +`dynAllocateVertices` is an *unchecked* bump allocator over a 50 KB/frame +pool shared with the whole scene, and pure tessellation wants ~1,200-1,300 +verts (~40% of it) at this camera. Options A (pure tessellation, no fast3d +change, ~40% of the pool), B (widen the texcoord transport in `port/fast3d/`, +then ~4x4 subdivision suffices, ~100 verts, wider blast radius), C (hybrid). +and **D — RDP tile shift, which dominates the other three and is the +recommendation.** `shifts`/`shiftt` in the tile descriptor is the RDP's own +precision-vs-range knob, and `port/fast3d/` already implements it fully +including the left-shift case (`gfx_pc.cpp` ~1783). Emit tc at `32/2^k` units +and set `shifts = 16 - k`: 2^k more range, **no tessellation, no fast3d +change, no vertex-budget cost**, authentic RDP idiom. `k = 5` gives ±32,767 +texels, covering the measured 29,830-texel span outright — i.e. exactly the +diagnostic build that already removes the artifact, with the scale corrected +rather than left wrong. Care needed: emit the shift on the sky's tile only +(an extra `gDPSetTile` after `texSelect`), and pick `k` per draw from the +measured span. **Ask the user before implementing.** + +**Recheck after the fix:** whether the M-96 "sky scrolls extremely fast" +complaint and M-98's measured ~7 px/tick were the same bug all along +(wrapped tc would make the apparent pattern move at a rate unrelated to the +true 1 texel/tick scroll). Plausible, unconfirmed. + +**Environment notes** (all still apply, plus M-99's below): `GE_PCDUMP` +writes to `./ppm/` **relative to the cwd you launch from** — run from the +repo root, not `build-pc/`, or the frames land somewhere you won't find them. +Backgrounding the exe with a trailing `&` inside a tool call kills it before +it captures; use a proper background run instead. + +## M-99 (2026-09-11) — human playtest: D227 seam STILL PRESENT after M-98's fold fix, AND view-angle-dependent. Headless repro blocked; needs a human co-session. + +**Human playtest result (this session, after M-98's fold-sharing fix was +pushed):** the seam is **still there on Statue**, and — new, sharper data +point — **it visibly moves/changes as the mouse/player view moves.** Also: +**"still pretty bad" on Cradle**, and **Surface has the same issue.** This +means M-98's fold-sharing fix was real (verified via static-frame diff, +findings.md §H "D227 — M-98") but is NOT the dominant thing being seen live +— same pattern as M-95's wScale fix before it. Read that finding fully +before touching sky.c again; don't re-derive it. + +**What this session ruled out, cheaply, before getting stuck:** +- **Cross-quad water/cloud texture-scale mismatch.** Hypothesis: block1 + (the "below-horizon" quad, `sp274`/`sp43c`, `skyRender`'s first big + switch) and block2 (the cloud quad, `sp94`/`sp4b4`, second switch) are + drawn from independently-computed vertex data that share the horizon + boundary but never share a `wScale`/fold — texture-scale differs by 10x + between them (`unk0c = raw` in block1's IsWater case vs `unk0c = raw*0.1f` + in block2, both lines confirmed by direct read). **Checked via the + existing `GE_D176` env probe: both Statue AND Cradle report `IsWater=0`.** + For `IsWater==0`, block1 is a flat `gDPFillRectangle` (`sky.c` ~874-897) + — no texture, no scroll, can't produce a texture-pattern seam. This + theory doesn't apply to either level actually tested; **still untested on + an `IsWater==1` level** (candidates: Frigate, Runway, Depot, Surface1/2 — + check with `GE_D176=1` first) where block1 WOULD go through + `skyPortBeginFan`/`skyRenderTri` textured and could genuinely conflict + with block2's independent fan. Worth ruling in or out properly before + the next session assumes it's dead. +- **Headless camera-pan repro is NOT wired up.** Tried to reproduce + "changes with view" headlessly via `GE_INPUTSCRIPT` — both sustained + analog-stick tokens (`SRIGHT`) and repeated C-button pulses + (`CRIGHT`/`CUP` etc.) across a 90-tick window produced **zero visible + camera rotation** in captured frames (same look direction throughout, + confirmed by identical HUD/weapon-arm framing). The real in-game + mouselook almost certainly injects yaw/pitch through a path + `GE_INPUTSCRIPT` doesn't touch (it only emulates the N64 controller: + buttons + one fake analog stick) — worth checking `port/src/input.c`'s + actual mouse-delta injection point for a debug hook, or adding one + (env-gated, e.g. `GE_FORCEVIEW=yaw,pitch` set once per frame) if this + investigation needs more headless angle sweeps. **Until that exists, any + view-angle-dependent visual bug in this game needs a human playtest to + chase, full stop** — don't burn another session's budget re-trying + `GE_INPUTSCRIPT` stick/button tokens for camera turn, they don't do it. + +**What's genuinely still open, ranked by how promising it looked before +getting stuck on repro:** +1. **Cross-block (water-quad vs cloud-quad) independent fan state, on an + `IsWater==1` level.** Not ruled out yet (see above) — check first, it's + cheap (one `GE_D176` run per candidate level) and if true it's a clean, + scoped fix (extend `skyPortBeginFan`'s shared state to span both blocks + in one frame instead of resetting between them — needs restructuring + since block1 draws before block2's vertices even exist; the two calls + would need to become "begin/accumulate/begin-again-without-reset/end"). +2. **Frame-to-frame popping at the fold boundary, not a same-frame spatial + seam.** `skyPortRenderPoly`'s fold recomputes fresh every frame from the + current scrolling min-S; each time it crosses a 64-texel boundary the + chosen fold jumps by 64 — *should* be invisible (GL_REPEAT period 64) + but was never independently verified to actually be seamless in + fast3d's real texture-wrap implementation for this specific combiner + setup. A static-camera, long, `step:1` capture bracketing a known + fold-crossing tick (derivable from the ~7px/tick rate measured in M-98) + would show this directly if real, and — importantly — this one doesn't + need view rotation to reproduce, just enough elapsed ticks, so it's + still headlessly testable. **Good first move for next session if a + human isn't available yet.** +3. **The clip-shape switch's discrete vertex-count/topology changes as + screen corners cross the horizon** (`skyRender`'s 16-case switch reruns + every frame from scratch; adjacent cases can hand block2 a differently + *shaped* fan, not just moved vertices) — could read as "the pattern + changes as you look around" without being a same-frame crack at all. + Not investigated. + +**Concretely blocked on:** a screenshot or precise repro detail from a +human — where on screen, at roughly what look angle/pitch, which level. +Asked for this at end of M-99; if it's in hand for the next session, START +there instead of re-running the ranked list above blind. + +**Also outstanding, unchanged:** D228 (AK47 white missing-texture patches, +different mechanism from the already-fixed D217 green-palette bug) is +still fully unstarted — reasonable fallback task if the seam investigation +needs a human and one isn't available yet. + +**Environment notes for whoever picks this up:** +- Launching `ge007.x86_64.exe` directly (not via `verify.sh`) needs + `export PATH="/c/msys64/mingw64/bin:$PATH"` first or it exits instantly + (code 127, no output) — DLL resolution, not a real crash. +- `run_in_background: true` + `taskkill //F //IM ge007.x86_64.exe` once you + have the frames you need is the normal pattern for a capture — the + background task will report "failed" (nonzero exit from the forced kill) + even on a fully successful capture.

A global timing bug would speed up everything, not just +the sky, so it isn't this. + +**Found + fixed:** M-95 shared `wScale` across a whole sky fan but left +`skyPortRenderPoly`'s S/T fold (`foldS`/`foldT`) computed per-call — the +exact same bug class, one field over, never touched. Two triangles sharing +a fan vertex could floor its S/T to different multiples of 64 texels; +nominally invisible (`GL_REPEAT` period 64) but each triangle bakes +`(S-fold)*32` into its own `s16` buffer, so two folds 64 texels apart = tc +values 2048 apart — a real crack.

PC MinGW lays them out in declaration order, so `arg1->f[1]` read **ymax-as-X** and `arg2->f[1]` read an unrelated stack float (observed `2.25734`, later `nan`) → the vertical hit band collapsed to a ~14 px strip at each wallet's bottom edge (sometimes NaN = unselectable). Exactly "click below the file." Fix: explicit `{xmin,xmax}`/`{ymin,ymax}` pairs under `#ifdef PORT` in `front.c` (N64 call untouched; ABI/layout exception per rule 2).

One paragraph version: `texAlignIndices` pads CI index rows to *absolute* 8-byte boundaries, and the model-DL `G_LOADTLUT` palette offset is a *formula* that only matches reality when the texpool base is 8-aligned. On N64 the memp bump allocations feeding these pools happened to be 8-multiples; PC pointer bloat (D36/D37-class struct growth) made some STAGE-bank sizes not, so on FACILITY both weapon-pool bases land %8==4 → every palette in those pools sits 4 bytes early → the grip's count=1 TLUT reads the next tenant's header slot (`texnum=26` → LE s16 → `0x1A00` = the green). The same mechanism explains M-86's "leading zero pad" tell on larger loads (palette 2 entries early ⇒ first two read entries are zero pad). BUNKER1 was clean only because its pool bases happened to be aligned. + +**Fix landed (working tree, uncommitted):** `src/game/image.c` `texInitPool`, `#ifdef PORT`: round the arena base up to 8 before publishing `start`; `end` unchanged (pool loses ≤7 bytes).

D217 probe extended + built; a local-Qwen triage's specific citations were caught WRONG on hand-verification (see below); the underlying mechanism was independently re-derived and looks solid. NOT yet run to completion — next session picks up at "read the run.log", not at square one. + +**Housekeeping done:** untracked `docs/dev/MODERN-PORT-FEATURES-BACKLOG.md` (from a concurrent session) moved to `docs/dev/notes/` (gitignored) per user instruction — do not treat this as new work, it's someone else's in-flight doc. + +**Local-Qwen dispatch result — DO NOT TRUST WITHOUT RE-VERIFYING.** Dispatched `triage` to investigate the D217 "stale-arena-pointer" lead (per M-89's exact spec). It came back HIGH confidence with specific citations: "`texWriteLoadToTmemAddr`'s only call site is `tex.c:918`" and "`texFindInPool` has only two callers repo-wide (`tex.c:405`, `image.c:2443`)". **Both are false** — direct grep shows `texFindInPool` is also called at `tex.c:856` and `tex.c:920` (same file it claimed to have fully searched), and `tex.c:918` is actually `texnum2 = (in->words.w1 >> 12) & 0xfff;` inside `texLoadFromGdl`'s `TEXTURETYPE_DETAIL` case — not a `texWriteLoadToTmemAddr` call at all. This is the exact "confidently fabricates" failure CLAUDE.md already warns about. Its overall shape (address baked once into a GDL at model/room-load time, reused pool) pointed in a directionally-useful place, but every specific line citation from it needs independent re-derivation, which is what the rest of this session did by hand. + +**What was independently verified by hand-reading the real code (trust this part):** +- `texWriteLoadToTmemAddr` (`tex.c:494`) emits `gDPSetTextureImage(gdl++, tex->gbiformat, depth, 1, tex->data)` — `tex->data` is a real `u8*` (`image.h:42`), and `gSetImage`'s packing macro (`include/PR/gbi.h:3106-3111`) stores it as `(uintptr_t)(i)` — a full 64-bit store, NOT a 32-bit-truncated N64 physical address. **This rules out a D3x-class pointer-truncation bug for this path** — a theory I formed and then killed myself before wasting a build cycle on it. Don't re-open this angle without new evidence. +- `texLoadFromGdl` (`tex.c:779`) — which bakes those addresses into a display list — runs only at object/room LOAD time: callers are `objecthandler_2.c:82` (model load) and `bg.c:2499/2601/2603` (room primary-GDL load, confirmed by the doc comment at `lightfixture.c:31` — "Room load ... texLoadFromGdl() walks the room's display list"). It does **not** run per-frame. +- `gfx_dp_load_tlut` (`port/fast3d/gfx_pc.cpp:2202`) — the draw-time consumer — does a **live re-read of memory at the baked address on every single draw call** (`base = (const uint16_t *)rdp.texture_to_load.addr + ...; *dst++ = PD_BE16(*src++);`, loop at line 2230-2234). It is NOT cached across frames; it always reflects whatever bytes currently live at that address. +- **Conclusion (HIGH confidence, own derivation):** the mechanism is real and matches the symptom shape exactly — a texture's address is baked into a model/room's DL once, at load time; every subsequent frame's draw re-reads that literal address fresh. If some OTHER later texture decode reuses the same `texpool` arena bytes (bump allocator, `image.c` `leftpos`/`rightpos`, no per-texture free/refcounting — confirmed at `image.c:2323-2328`, `2508-2525`) before the first model's DL stops being drawn, every frame after that point reads the new tenant's bytes — permanently, matching "solid green from a fixed point onward, never intermittent." This does not require N64/PC to differ in the C code (AGENTS.md ground truth holds) — the divergence must be in *pool sizing/reuse cadence* between platforms, not logic. + +**Probe extension shipped this session (built, NOT yet run to a read result):** +- `src/game/image.c` (`texInflateZlib`, `#ifdef PORT` `GE_D217TEX` block) — added `addr=%p` (the `dst` pointer, i.e. `tex->data`) to the existing decode-time log line. +- `port/fast3d/gfx_pc.cpp` (`gfx_dp_load_tlut`) — added a new `GE_D217TEX` log (`D217TEX-DRAW addr=%p pal0=%04x pal1=%04x count=%u`, via `sysLogPrintf`, NOT `osSyncPrintf` — that doesn't link into `port/fast3d`, cost one failed build to learn) logging a **live re-read** of the palette bytes at draw time, keyed by address (texnum isn't available at this layer — correlate the two logs by `addr=`, not by texnum). +- Both builds clean (`./build-pc.sh ntsc-final`, MSYS2 MINGW64 PATH). Neither is applied/committed yet — working tree only. +- **Hit one environment snag:** the build failed once with `ld.exe: cannot open output file ... Permission denied` — a leftover `ge007.x86_64.exe` (PID from an earlier/concurrent run) had the file locked. User approved killing it; by the time `taskkill` ran the process had already exited on its own. If this recurs, check `tasklist //FI "IMAGENAME eq ge007*"` before assuming the build is broken. + +**Exact next step (do this first, it's cheap):** `tools_pc/verify.sh` was run once (`GE_D217TEX=1 ./tools_pc/verify.sh facility`, PASS, 3 frames) but the session ended before locating/reading the resulting log. `verify.sh` writes the run's stdout+stderr to `"$capdir/run.log"` (see `tools_pc/verify.sh:184`, `CAPDIR="$capdir"` set at line 231) — **find that capdir** (likely under a `tools_pc/`-relative temp/capture dir printed by verify.sh itself, or grep `verify.sh` for how `capdir` is constructed if not obvious) **and grep it for `D217TEX` lines.** Correlate the decode-time `D217TEX texnum=... addr=...` lines against the draw-time `D217TEX-DRAW addr=...` lines by address: if any `addr` shows a *different* `pal0` between its most-recent matching decode-time line and a draw-time line that comes after it, that is direct proof of the stale-arena-pointer mechanism, and narrows the fix to whichever call site re-runs `texInitPool`/reuses that arena region while an earlier consumer (a still-drawn weapon or room model) is still alive. If the addresses never collide in this FACILITY run, extend the capture window or try the exact BUNKER1-vs-FACILITY pairing from the M-89 decode-only probe (frame ~300, post-vent-drop-cutscene) with both probes active together. + +**Not done this session, unchanged from M-89:** PR #43 (D176a sky) still draft, still owed a human eyeball on `-level_22`/Cradle.

The already-written, previously-untested-against-this-repro +parked fix `fix/d217-model-texture-palette` (CI-cache content-hash, defect +②) was built and run directly against the FACILITY repro **and still shows +green** — so defect ① is NOT the same bug as ②, don't expect ②'s merge to +fix this. **Current best lead (untested): a stale/dangling `tex->data` +pointer into the `texpool` arena** — probe the draw-time address vs. the +most-recently-decoded content at that address (spec + probe extension +notes in findings.md D217, search "stale-arena-pointer"). A `GE_D217TEX` +env-gated probe is already in tree (`src/game/image.c`) logging +decode-time `texnum`/`palette[0..1]` — extend it with an address field +rather than starting over. + +**Goal for this arc:** ship v0.2.0 in the next few days, fidelity-only scope +(graphics + audio 1:1 with N64; hard QoL out of scope — see +`docs/dev/notes/ROADMAP-1.0.md` "M-87 triage" section, which IS the priority +order). Tier 1: D217 (weapon/NPC texture palette) > D77 (in-level music +missing, hard-gates UNLOCKED-FPS-PLAN/WIDESCREEN-FOV-PLAN) > D176(a) (sky). +Tier 2 (after Tier 1): D222+D218+D220 FOV-slider break-set, D148/D160/D173 +cutscene actors, D219 purple explosions. QoL items (D194, D223, D224, D225, +D226, D211-as-degrees, D218-as-slider) are explicitly OUT OF SCOPE this pass. + +**Usage note (mid-session):** user flagged we were at ~70% of the cloud +usage limit; killed one just-started cloud subagent (D217 follow-up) with +near-zero loss, paused further cloud subagent dispatches, and switched to +the local Qwen delegate (`delegate-local` MCP, cost-free) for further D217 +work once its backend (LiteLLM proxy + Unsloth Studio) was confirmed up. +**If picking this up in a new session, check the local backend first** +(`local_backend_status()`) — it was down for a stretch this session, up by +the end. + +**Landed this session:** +- **PR #39** merged (`e117c0d7`) — golden bunker1 re-baseline (D215) + + M-85 D217/D211 triage docs.

Fix: a custom projection matrix gives each vertex +its real camera-space `w` (already computed upstream, `unk0c`, previously +unused) while keeping screen-space x/y unchanged, so the GPU's normal +perspective divide does the right thing — same pipeline every other textured +draw already relies on.

The M-73 withdrawal and the pan audit below both still stand.** Re-counting the same capture shows the "idx 109 barrage" is normal in-spec guard combat; the one untested layer left is spatial presentation (pan/volume). **Next session starts here.** + +**M-74 (findings.md D205 + §F row + porting-notes §E).** M-73 concluded that +guards were stuck re-triggering fire sound idx 109 ("256x over 29.7 s, no +bullets") and pinned it on `stanTestLineUnobstructed` guard→Bond LOS over +converted collision geometry, then queued a full pccg-stan decode + ray-replay +investigation. **Re-counting the same file (`build-pc/audiotrace.log`) breaks +every load-bearing number:** + +- idx 109 is requested **128×**, not 256 — the `GE_AUDIOTRACE` double-log + artifact **D204 already corrected for M-63 on this exact sound index**. + Count `sndPlaySfx: t=` lines, never bare `soundIndex=` matches. +- 128 / 29.73 s = **4.31/s aggregate** across ~11 guards ≈ **0.4/s each** — + about **6× UNDER** the AK47's own `SoundTriggerRate` (`RATE_AK47` = 4 + `g_GlobalTimer` ticks ⇒ 15/s per guard ceiling). The `field_178` gate that + M-73 accused never binds. +- "No bullets/impacts" is false: the same window holds ~30 ricochet/wall-hit + requests (19–41), 69 ×2 flesh, 12 body-falls (123–132), 14 guard yelps + (134–147). Guards were firing *and* hitting. +- The striking monotone sweeps 134→147 and 123→132 are the ground-truth + round-robin `male_guard_yelp_counter` (`chraction.c:2454-2470`) — faithful + cycling in byte-matched code, not a broken `random() % n`. + +**Do NOT open the pccg-stan / LOS geometry investigation on this evidence.** +The only open observation left from that capture is that the firefight lasted +a while, which is a gameplay-fidelity question for an N64 A/B. + +**Where D205 stands.** Everything upstream of presentation is proven: bank +conversion 261/261 identical (M-71), sample+pitch exact (M-68/M-70), and every +requested index in the capture correct (182 explosion ×1, 81 armor ×1, +46/47/48/49/105). That leaves **one untested layer: spatial presentation — +per-voice volume, pan, concurrency.** It explains all four complaints in one +shape (a wrongly-placed sound is, by ear, a sound at your own position: "a gun +sound came out of my punch", "the explosion screamed", "a slap over my +gunshot"), and it is the youngest code in the stack — `sndCreatePostEvent` was +stubbed out entirely by D138 until M-65 un-stubbed it, and has never been A/B'd. + +**Ranked:** H-A pan/spatialisation wrong or absent in the mix (top) · H-B +distance law right but scale wrong (`[DISTVOL]` follows the documented curve +yet only reaches 0.60 of max at dist 1794; never compared to N64) · H-C +voice-pool masking (weak — M-70 measured alloc ≤ 5/8) · H-D PC guards +genuinely engage where N64 guards don't (possible, but now with *no* +supporting evidence; gated behind the N64 A/B). + +## Previous session (M-73) — D205: proposed a guard LOS/collision root cause. **WITHDRAWN by M-74 above — the counts it rests on do not survive re-derivation. Kept for history; do not act on its next-steps.** + +**M-73 (findings.md D205 + §H):** analysed the user's full-combat +`GE_AUDIOTRACE=1` capture (`build-pc/audiotrace.log`, 288 unique requests). +**idx 109 (`GUN_B4_BOLTACTION_SFX`, AK47/Spectre fire sound) is requested +256× over 29.7 s**, from ~11 distinct NPC state slots, each on its own fixed +period (median gaps 200/434/499/698/934/1299 ms — multiples of ~200 ms). +Only ~32 non-109 requests exist in the window (~0.6/s) → **guards re-trigger +weapon fire sounds WITHOUT firing bullets** (no impact SFX at 10×/s). Code: +`chrlvFireWeaponRelated` (`chraction.c:6530`) passes `phi_a2 = sp27C || +sp278` to `sub_GAME_7F02BFE4` (:6902) — non-bullet auto ticks (sp278) still +play the weapon sound, gated only by `SoundTriggerRate`/`field_178`; so +sustained ACT_ATTACK = sustained roar. Sustained attack needs +`seen_bond_time >= g_GlobalTimer - 100` (:6593), refreshed by +`setSeenBondTimeToNow` behind `stanTestLineUnobstructed(...OBJS|DOORS|CHRS| +PATHBLOCKER|AIOPAQUE...)` LOS queries (:3917/:3972, `chrCanSeeBond` :3945). +**Leading suspect: converted collision geometry makes guard→Bond LOS return +clear where N64 blocks → guards never lose their target.** Per symptom: +(1) "Klobb on melee" — 106 was NOT requested anywhere in this capture, and the user WAS punching in it (47/48/49 ×13, 105 ×19, all voiced); the only gun sound present during those punches was the 109 barrage. OPEN: is the heard "Klobb" a 109, or a real 106 from another session? (Klobb = specific SMG = Skorpion, idx 106 — user's N64 A/B identification stands; do not assert misidentification.) Decisive: ROM samples 106 vs 109 as WAVs for the user + targeted punch capture. +(2) "explosion→scream" — 182 requested once (correct); GET_HIT_MALE +(137–139) ±1 s around it, all under the barrage. (3) "armor wrong" — 81 +requested once (correct!), bracketed by 109 ticks. Same phenomenon as D202 +M-63's unexplained idx-109×94/60 s anomaly. + +## Done this session (M-72) — D205: fourth symptom added (unarmed melee → Klobb shot idx 106); controlled `GE_AUDIOTRACE` runs exonerate every request path; mechanism (b) extra-events now the leading suspect. + +**M-72 (findings.md D205 + §H):** environment fix first — the "flaky /GS +crash" was `SDL2.dll` missing from PATH (`C:\msys64\mingw64\bin`; exe is +`-mwindows`, so a DLL-load failure just dies 0xC0000105, no console). Launch +via `build-pc/d205_*.ps1` (gitignored) which prepends it. Controlled traces: +(1) PPK fire at `-level_09`: per shot exactly {46 GUN_SILPPK, one of the +20-entry `ricochet_sounds_small` table (gun.c:415 — `rnd1 % 20` is IN RANGE), +122 CART_SPENT} — no glass/slap layer. (2) Levels 01–08 all start unarmed; +fire-press requests ONLY 105 PUNCHING_AIR (whiff). (3) Static: punch hit = +constant {47,48,49} (gunfire.c:2338); idx 106 is data-only +(`skorpion_stats.Sound = 0x6A` via `bondwalkItemGetSound`); the player +fire-sound path (gunfire.c:3192–3200) needs `GUN_ANIM_STATE_FIRE`, which a +fist never enters — so Bond's own punch CANNOT request 106; an NPC guard +firing its Skorpion (`chraction.c:5588`) can. **No symptom reproduces in +micro-scenarios → the layering must come from extra/different EVENTS during +real gameplay (mechanism b).** + +### Previous session (M-70 + M-71) — D202 data-closed AND by-ear-closed: probe removal + close is all that remains. NEW ACTIVE TASK: **D205** — PC requests wrong/extra SFX indices vs N64 (explosion→scream, armor pickup wrong sample, slap/glass over gunfire); bank converter + playback chain exonerated. + +**M-70 (findings.md):** decisive clean re-capture, 209 scripted `-level_09` +requests → every voiced request plays the exact ROM sample at the exact ROM +pitch (200/209 auto CC ≥ 0.85; the 4 MID are idx=109 verified 0.946 by +manual ratio sweep; the 5 NO-WIRE = 1 matcher window artifact + 4 +never-voiced requests, NOT pool exhaustion — alloc ≤ 5/8 at each drop). +Zero wrong-sample playback. Matcher v3 fixes in `scratchpad/exact_match.py`: +death-clip both sides, slide() sparse-tail bug (step-1 over 0..2205, +step-4 across the span, ±8 refine), PLAY window 600 ms → 2 s. Output: +`scratchpad/exact_run6_match.out`. Trace files in `build-pc/` +(`audiotrace.log`, `audiotrace_wire.log`, `voicedump.raw`). + +**M-71 (findings.md):** user by-ear pass on M-66b = **PASS** ("the metal +door sound does not loop forever now") — Disposition C validated; D202's +only remaining step is probe removal + close. The user then reported a NEW +complaint class, N64-A/B confirmed non-faithful: (1) slap/glass layered over +general gunfire (audible on PC, silent on N64), (2) explosion plays a +soldier-scream sample, (3) armor pickup wrong sample. Split out as **D205**. +This session exonerated the two remaining static suspects: the D37 bank +converter offline (`scratchpad/banktest/`: real `romdataFixupAudioBank` +harness + `diff_bank.py` → 261/261 entries identical N64 vs PC, 0 +mismatches) and the D154/D135 GBI raycast parsers + volume law (static +re-audit, ABI-correct). So D205 = **PC requests different or extra sound +indices than N64** — converted level/setup data (sndID / explosion-type / +item-sound fields in pccg sidecars) or extra hit events from converted +collision geometry. Full ranked next-steps in findings.md D205. + +### Next session, in order (M-74 updated — M-73's list is withdrawn): +1. ~~D205 step 1, static audit of the presentation layer~~ — **DONE this + session. H-A FALSIFIED.** The port's stereo path is correct end to end + (`snd.c:461/530` → `alSynSetPan` → `env.c:400-402` eqpower L/R targets → + `port/src/mixer.c` `aEnvMixerImpl` independent `dry[0]`/`dry[1]` gains), + **but GE never uses it**: `AL_SNDP_PAN_EVT` has no poster anywhere in the + tree, and 252 of 261 bank sounds have `samplePan == 64` (`AL_PAN_CENTER`) — + every index in the user's capture included. **GE does not spatially pan SFX + on either platform.** Bank `panvol` re-diffed 261/261 clean (closing the one + field-coverage gap in M-71's prose). Volume formula has no PC-side overflow + divergence. +2. ~~D205 step 2, pan probe run~~ — **cancelled: pan cannot vary, by design.** +3. **The PC side of D205 is exhausted.** Bank, playback, requested indices, + sample+pitch, pan and per-sound volume are all verified faithful. GE's only + spatial cue is distance volume, and it is shallow by design (0.60 of max + still at dist 1794) — so a guard firing across the room plays near-full + volume, dead centre, at a per-sample volume comparable to the player's own + punches (109 = 90; 47/48 = 100; 49/105 = 110). That is faithful *and* it is + exactly the condition that produces all four complaints. **Only H-D remains + — does the PC generate MORE overlapping combat events than the N64 — and + nothing on the PC alone can settle it.** +4. **⇒ The N64 A/B is now the gating step (user-side, owed).** Batch it: + (a) ROM samples 106 (Skorpion / "Klobb") vs 109 (AK47) as WAVs via + `scratchpad/rom_sfx_decode.py` for the user to settle the Klobb + identification by ear — their identification stands either way, this decides + *which* sound, not whether they heard it; (b) N64 A/B: punch a guard while + others fire — does the same combat sustain, and does the same layering + happen, on N64? If N64 sounds the same, D205's four symptoms are faithful + and the finding closes as NOT-A-BUG. If it does not, the difference is + gameplay-side (guard engagement), and *that* is when the collision/LOS + geometry work becomes justified. +5. **Close D202:** remove the probe set — `[VOL]` (`src/snd.c:556`), + `[DISTVOL]` (`src/game/propobj.c:12780`) + its `#include "audiotrace.h"`, + and the rest listed in GE-ENV-PROBES.md (`[WIRE]`, `[EVT]`/`[STOP-EVT]`, + `[VOICE±]`, `[SLOTWRITE]`, `[ENVELOPE]`, `[VOICES]`, `[RETRIGGER-POST]`, + `[WAVELOOP]`, `[DOORSND]`, `[VOICEMAP]`, `[MISSIONSTATE]`, `[MUSICNOTE]`, + `[EVTQ-DROP]`, `[PASTEND]`). **KEEP `[EXPIRE]`** — part of the M-66b fix, + not a probe.

Voice leak (the "eventual silence" cascade) — CONFIRMED, MEASURED, guarded.** +`soundIndex=203` (`METAL_SLIDE_CLOSE_SFX`) has `envelope->decayTime == -1` +(genuine ROM data — verified at the source-bank level with new `GE_BANKDUMP`/ +`GE_KEYMAPDUMP` probes) → `SOUND_FLAG_LOOPED` → never posts STOP_EVT, and the +preemption scan refuses to steal looped voices. `doorPlayCloseSound0/1` play it +with a `NULL` owner, so nothing can ever deactivate it. Measured on 115 s of +headless `-level_09`: **7 of 8 voices permanently held by sound 203**, leaving +one usable voice for the whole game — every later SFX gets a state but no +voice and is dropped. Fix: 4-line guard in the `src/snd.c` preemption scan +reclaiming only provably-ownerless loops (`LOOPED && !RETRIGGER && +state->state == NULL`). Measured: acquisitions 171 → 629, count no longer +pinned at 8, residual stuck voices 7 → 1. User confirms "less cascading". +**This is a rule-#2 game-code change justified by measurement, not ground +truth — kept flagged as a documented port-side deviation.** + +**2. `sndCreatePostEvent` un-stubbed (D138) — FIXED.** The D138 stub had been +silently removing ALL distance-based volume attenuation (every caller posts +`AL_SNDP_VOL_EVT`). Its O(n²)-watchdog premise expired when the Phase-3 audio +thread landed. Removed; re-measured clean (`rt=0.996`, drop 0, no watchdog +trips over 115 s). Likely a large part of the "wrong/too-loud/multiple sounds" +impression. + +**3. Audible endless door loop — still NOT reproduced.** Ruled out by +measurement (do not re-walk): wave-level looping (`loop==NULL` on every sound), +decoding past wave end (`[PASTEND]` 0 hits), stale/accumulating DMEM (full +per-frame wipe → unchanged), undamped reverb feedback (`GE_NOWET` → unchanged), +retrigger posts (0), door oscillation (~4 cycles/door/110 s, normal). +Corrections banked: the `romdataFixupMusicSeqTable ... capacity 1` error is +BENIGN (deliberate first call); the ~1400-RMS "drone" in AUDIODUMP captures is +background music (`csplayer.c:535`), not a stuck sound. + +**Next step (what the session ended asking for):** user capture at the failing +door (computer-room double doors, or a level start whose attract intro shows +them opening) with `GE_AUDIOTRACE=1 GE_AUDIODUMP=1 ./ge007.x86_64.exe -level_09`, +then send `build-pc/audiotrace.log` + `build-pc/audiodump.raw`. The dump lets +the stuck sound be isolated numerically (separated from music) and pinned to +the exact door event via `dumppos`.

D202 still OPEN; two M-63 conclusions corrected. + +**New finding D204, fixed and measured.** Found by reviewing the audio +*pacing* loop — the whole M-56→M-63 chain had been auditing the data path. + +**The defect:** `amMain` wakes at 30 Hz (`sched.c:334` forwards every 2nd +retrace to the audio client, `audi.c:441`) and asks for `g_MinFrameSize`=720 +samples per block = **21600/s against a 22050 Hz device** — structurally 2 % +short. `audi.c:531` relies on 784-sample top-up blocks to make it back, but +only requests one once the reported AI length drops under ~69 frames = **3 ms**. +Fine on N64 (double-buffered AI, exact VI interrupt); on PC ordinary OS +scheduling jitter empties a 3 ms cushion before the loop reacts, the SDL queue +hits zero, and the device pads playback with silence — **unrecoverable time, a +queue-depth reading cannot tell the regulator it already fell behind.** +Measured `rt=0.980` sustained with `q` repeatedly at 0, indefinitely, on every +level, for every user, since the first frame. + +**The fix (F5, port-only — `src/audi.c` untouched, rule #2 clean):** +`audioGetAiLengthBytes()` in `port/src/audio.c` subtracts a 1024-frame +(~46 ms) cushion before reporting, so "queue holds the cushion" reads as +"queue is empty" and the loop tops up while slack remains.

The "suspicious uniform ~32.6 ms cadence" is just the + audio-block quantum (720 frames × 4 = 2880 bytes) that *every* `dumppos` in + the trace is rounded to. +2. **M-63's "8 s of audio in a 60 s run" was its own probe's artifact.** + `GE_MIXERTRACE=1`'s unbuffered per-opcode `fprintf` (25 MB log) slows the + process enough to starve the audio thread. Same repro without it: 58.0 s / + 60 s. **`GE_MIXERTRACE` is unsafe for any timing-sensitive measurement** — + M-63's advice to have the user replay with it set would have induced the + very starvation being hunted. Use `GE_D204` instead. + +**A hypothesis I raised, tested and FALSIFIED — do not re-open.** I predicted +the u32 subtraction at `audi.c:531` wraps past 789 queued frames, truncates to +u16 (58128), and drives a 74× heap overrun of the 3156-byte `info->data`. The +wrap is real (high-water 2064 frames measured) but **harmless**: +`frameSamples` is declared **`s16`** (`audi.c:145`), so it lands negative and +audi.c's own lower clamp catches it. Max block stays 3136 B vs the 3156 B +allocation in every run, both modes. No overrun. This is why F1 measures as a +no-op. + +**D202 is NOT resolved by this and stays OPEN.** Nothing degraded in any +headless run this session (5 min soak clean, no voice-pool growth). Its +reported chain — wrong PPK sound, correct one sometimes heard too, pile-up, +eventual near-silence except a stuck loop — still needs a **real playtest**. +**Next session:** have the user play with `GE_D204=1 GE_AUDIOTRACE=1` (and +**not** `GE_MIXERTRACE`) and hand back `ge007.log` + `audiotrace.log`; `rt` +falling or `q` pinning at `queueLimit` with `drop=` climbing localises it +immediately.

Full +detail: `docs/dev/findings.md` D204. + +## Done this session (M-63) — D202 REOPENED again: user's real complaint is runtime mixer/voice corruption, not a wrong-sample-data question. Live repro built; root cause not found; one concrete anomaly banked. + +**Supersedes the M-62 "recommend close" below** — after that was written, the +user clarified the actual bug: the wrong ("slap") sound always plays on the +silenced PPK, the correct suppressed shot **sometimes plays too** (both heard +together), and over a play session sounds "pile up and spirally glitch out" +until eventually **no audio plays except a looping sound (e.g. Bunker's door) +stuck since level start.** That's real-time mixer/voice-lifecycle corruption, +categorically different from "wrong soundIndex requested" — the M-56–M-62 +chain (which is solid) never actually tested this. + +**Build+run works in this environment**: `export +PATH=/c/msys64/mingw64/bin:$PATH` (MSYS2 MINGW64 gcc/cmake/SDL2), then +`./build-pc.sh ntsc-final` from repo root. To run, `build-pc/data/` needs +the **full** asset set, not just the ROM: copy `data/pccg-ntsc-final/`, +`data/pcmodels-ntsc-final/`, `data/ge007.ntsc-final.z64`, and (to match the +user's real state) `data/ge007.eep`+`data/ge007.ini` into `build-pc/data/`. +**A costly false alarm this session**: skipping the sidecar dirs makes +`-level_09` hard-crash in `load_bg_file` almost immediately (raw big-endian +ROM read instead of the converted PC sidecar, per `obInit()`'s own comment) +— looks exactly like a scary new engine bug, cost a stashed rebuild + a gdb +session to rule out, and was purely a test-setup gap. The `[WARN] +pcmodels.bin not found` / `[WARN] pccg.bin not found` lines are printed +right there in the log — read them before chasing a crash. **Next session: +always mirror the full `data/` dir, verify with those two warnings absent.** + +**Repro used**: `GE_MIXERTRACE=1 GE_AUDIOTRACE=1 GE_AUDIODUMP=1 +GE_INPUTSCRIPT="600:R,Z;601:R,Z;...;3210:R,Z;3211:R,Z"` (30 fire pulses, +~0.75s apart) `timeout 60 ./ge007.x86_64.exe -level_09`. Ran clean 60s, no +crash. Logs saved: `scratchpad/d202-m63/{audiotrace.log,mixertrace.log, +audiodump.raw}` (mixertrace.log is 25MB — grep it, don't read it whole). + +**Ruled out**: voice-pool exhaustion/leak. Only 16 distinct voice slots used +across 153 `sndPlaySfx` calls in 60s, properly recycled; `sndDeactivate` +count (159) tracks `sndPlaySfx` count (153) almost 1:1. The D199/M-53–M-55 +"voices never freed" lineage does not reproduce here. + +**Found, unexplained — top lead for next session**: `soundIndex=109` +(`"109_GUN_B4_BOLTACTION_SFX", //used for AK47`, `bondconstants.h:2546`) +fired **94 times in 60 seconds** with no AK47 anywhere in the repro (PPK +only), and part of that traffic retriggers the *same* voice slot at a +suspiciously uniform **~32.6ms cadence** (2880 bytes in the mixed stream, +4-in-a-row) — far faster than any plausible weapon cadence in this game. +Reads like something re-issuing `sndPlaySfx` every audio tick instead of +once per game event, which would explain "sounds piling up." Not yet +confirmed as the cause of the user's exact symptom (109 isn't the PPK's +sound), but it's the most concrete, checkable thing this session produced. + +**Not reproduced**: the user's full described chain (pile-up → glitch → +total silence except one stuck loop). The 60s/58-shot synthetic burst +stayed healthy. Either it needs a longer/denser real-play session, or the +soundIndex=109 anomaly is the seed that compounds given more time — chase +(1) below first, it's cheaper than an extended blind playtest. + +**Next session, in order:** +1. Find what calls `sndPlaySfx(109, ...)` in `src/game/*.c` and determine + if the ~32.6ms retrigger is legitimate (real per-round automatic-fire + loop, just fast) or a bug re-firing every audio tick instead of once per + event. +2. If that doesn't explain it, build a much longer repro (5+ min, walking + + intermittent combat) or have the user reproduce with + `GE_MIXERTRACE=1 GE_AUDIOTRACE=1 GE_AUDIODUMP=1` set and hand back the + logs, aimed at reaching the "total silence except one stuck loop" end + state; diff voice-slot reuse timing against this session's healthy + 60s baseline. +3. Actually listen to `scratchpad/d202-m63/audiodump.raw` (raw s16 stereo + 22050Hz PCM) around the soundIndex=109 retrigger timestamps — not done + this session, log-analysis only so far. +4. Do NOT re-open the index/data/decode/ROM-offset chain (M-56–M-62) — that + part is solid; this is a different mechanism. + +No code changes this session (build+run+trace only; the pre-existing +uncommitted diagnostic files were exercised, not edited).

No MIPS toolchain is available in this +environment (`mips-linux-gnu-*` absent) so M-61's item 1 (build the N64 +target, read the map/ELF for the literal ROM byte) wasn't attempted — went +for the cheaper item 2 instead. + +**Found `scripts/ge007.u-test_basis.csv:946`: +`0289c36e967840bba7f6fbd026dda001,.data,build/u/src/game/gun.o`** — +`test_files.sh`/`test_files_readme.md` confirm this md5 is a known-good +checksum of `gun.o`'s compiled `.data` section, which is where +`wppksil_stats` lives (`gun.c` `#include`s `gunWeaponStat.inc.c`).

Re-read the file: +`.Sound` is still `0x2E`. Since AGENTS.md rule #2 means the PC-port work +never touches `src/game/gun.c` / `assets/obseg/gun/**`, nothing has +drifted since that checksum was captured. + +**Also found: this repo's own CI (`.github/workflows/ci.yml`) never builds +the N64 target** — `validate`/`linux-build`/`windows-build` are all PC-port +jobs, no `test_files.sh`/N64 `Makefile` invocation anywhere. The "byte- +matches ROM" claim in `AGENTS.md` is inherited from upstream +`n64decomp/007`'s own history, not continuously re-verified in this repo. +Worth knowing generally; orthogonal to D202. + +**Net effect:** this is strong circumstantial evidence, not a rebuild- +confirmed "pass" (that still needs installing a MIPS toolchain and +literally running `scripts/test_files.sh`) — but combined with M-61's +already-closed alternative (c) (no runtime remapping), the two live leads +left are **(b) reference-clip provenance** and **(d) envelope-match +reliability**, both pointing away from a port bug. + +**Asked the user directly (same session): where did `B00I00S2D.wav` come +from?

Both live threads from +M-60 are done: + +1. **Bank-navigation off-by-N hypothesis: CLOSED (negative).** + `port/src/romdata.c`'s bank re-layout walks `ALBankFile -> ALInstrument + -> ALSound` in exact ROM order; PC index N == N64 index N.

Full 261-sound bank scan: + **index 45 (`DROP_GUN_SFX`) is the only strong match for the user's + reference clip (envcorr +0.999); index 46 (`GUN_SILPPK_A_SFX`) is the + "slap"** (`scratchpad/romsfx_44..60.wav`). +3. **Fire path traced:** `gunfire.c` L3196/3200 → `bondwalkItemGetSound()` + (`gun.c` L1343) → raw u16 `WeaponStats.Sound` (offset 38). No runtime + remapping. Both N64 and PC builds compile the same initializer from + source (`gun.c:135` includes the aggregate `gunWeaponStats.inc.c`; + per-weapon file is an identical second copy) — both say `.Sound = 0x2E` + (46). Unsilenced PPK uses 0x6B. + +**Keystone logical constraint (new):** the N64 build byte-matches the +original ROM, and this data is *compiled* from source in that build — so a +transcription error in `.Sound` would have broken the match. **0x2E is +therefore almost certainly what the original ROM holds**, meaning real N64 +hardware also requests index 46. That contradicts the reference clip +matching index 45, so exactly one of these is false: (a) byte-match verify +doesn't cover this data segment; (b) `B00I00S2D.wav` isn't an in-game N64 +capture (filename looks like a media-library asset ID — provenance never +stated); (c) N64 runtime resolves 46 differently than ROM order; (d) the ++0.999 envelope match is misleading. + +**FAILED this session — do NOT repeat:** direct ROM byte-pattern searches +for the struct (looped 40+ times, all 0 hits: decompiled floats don't +round-trip to IEEE-754 bits, integer tails also absent) and a hand-computed +RAM→ROM mapping (yielded offset `0xC11934` > 12MB file size; `.csegment` +sits at ROM `0xC00000` = EOF in `ge007.ld`, so the arithmetic was wrong). +No N64 `.map` at maxdepth 3 (only PC CMake tree `build-linux/`). + +**Next session, in order:** +1. Find the **N64 build map file or ELF** (search deeper than maxdepth 3: + `assets/obseg/Makefile.*`, `ld/`, `dist/`; then `nm`/`objdump`) and read + the actual 2 ROM bytes at `wppksil_stats.Sound` (vaddr `0x800326C4` + + offset 38). ROM=0x2D → transcription error (audit why verify missed it); + ROM=0x2E → ground truth, pivot to (b)/(c). +2. Check the **byte-match verification tooling**: does it compare data + segments or code only? Find the last full-verify output. +3. **Ask the user one question:** where did `B00I00S2D.wav` come from? +4. Cheap corroboration: live PC trace of the soundIndex passed to + `sndPlaySfx` on PPK fire (expected 46). + +Full detail: `docs/dev/findings.md` D202 M-61 entry. + +## Done this session (M-60) — D202 REOPENED: user rejects "ground truth, not a bug" and supplies a real reference clip. STILL OPEN, do not close. + +**User's own words: "I know for a fact its the wrong sound playing in the +PC port specifically."** This directly overrides M-59's conclusion below — +do NOT treat D202 as closed/WONTFIX. The user also dropped a real reference +recording of the silenced PPK's actual fire sound: `scratchpad/ +B00I00S2D.wav` (untracked/scratch, mono/16-bit/16kHz, 0.204s). Its RMS +envelope is sustained (stays high for ~80% of the clip) vs. +`d202_soundindex46_isolated.wav`'s early-peak-then-fast-decay shape — +consistent with, though not proof of, the user's "slap not gunshot" call. + +Two live threads, neither finished — **pick up here next session**: + +1. **Bank-navigation-bug hypothesis (new, not yet checked)**: soundIndex 46 + is *named* `46_GUN_SILPPK_A_SFX` in `bondconstants.h` yet decodes to what + the user twice ID'd as the melee-slap sound (whose own indices are the + adjacent 47/48/49 `_PUNCH*_SFX`). A correctly-resolved sound shouldn't + contradict its own debug label — check whether `port/src/romdata.c`'s + bank re-layout (`afCtx`, `_bnkfPatchWaveTable`) walks + `ALBank->ALInstrument->ALSound` in the exact ROM order, i.e. whether the + PC conversion could be off-by-one/off-by-N vs. `src/snd.c`'s documented + resolution path `soundBank->instArray[0]->soundArray[soundIndex]`. Not + checked line-by-line against actual ROM bytes for this bank yet. +2. **`scratchpad/rom_sfx_decode.py`** (WIP, untracked, NOT working yet) — a + fresh standalone ROM bank parser meant to decode a *range* of + soundIndex values and diff each against `B00I00S2D.wav` to find which + one actually matches. **Its ADPCM predictor loop is currently wrong** + (stubbed intra-subframe accumulation). The correct formula, confirmed + from `port/src/mixer.c`'s `aADPCMdecImpl` (L185-239, ground truth): + table shape `sAdpcmTable[predictor][2][8]`, per sample `j` in a subframe + `acc = tbl[0][j]*prev2 + tbl[1][j]*prev1 + (ins[j]<<11) + + sum_{kbase += table` (`src/libultra/audio/bnkf.c`) + — GE's wavetable *sample data* (unlike the bank-structure metadata) is + never relaid-out by `port/src/romdata.c`; it points straight into the + live cart-mapped `.z64` image. Last theoretical gap in the M-56/M-58 + data-integrity chain is now closed at the raw-byte level. +2. **Re-read the full `audiotrace.log`, not just soundIndex 46/122.** + Cross-referenced every other soundIndex against `bondconstants.h`'s + `"NN_NAME_SFX"` string table (index baked into the name). Every single + fire (46) request in the trace is immediately followed by one of + `{23, 24, 25, 37}` = `RICO_6_TAJ_A/B/C_SFX` / `RICO_5_C_SFX` — ricochet + impact sounds — cycling per shot. Found the call site: + `src/game/gunfire.c`'s `recall_joy2_hits_edit_detail_edit_flag()` + (unmodified ground-truth bullet-hit handler): any hitscan that strikes a + non-character prop unconditionally plays a random ricochet SFX from a + 20-entry table. **This is exactly what GoldenEye does when you shoot a + wall, on real N64 too.** + +**Conclusion:** the M-52/M-56 repro's fixed aim direction has the player +shooting straight into a nearby wall the whole time, so every shot +legitimately plays THREE correct sounds at once — fire (46) + cartridge- +eject (122) + a random ricochet (23/24/25/37) — not one wrong one. The +"sounds like ricochet + melee slap" description matches a ricochet impact's +character far better than a coincidental bug that always produces two +other real, nameable sounds. Three full sessions (M-56/M-57/M-58) of +independent bit-exact/byte-exact verification found nothing wrong anywhere +in the chain, which is now explained: there was nothing to find. + +**Not yet proven:** whether the fire SFX itself is perceptually prominent +enough / correctly balanced against the (real, expected) ricochet — could +just be masked by a louder transient, which is normal. **Recommended next +session, before resuming M-58's envmix/PVoice trace:** rerun the same +`GE_AUDIODUMP` capture with the aim pointed at open air (no wall hit), confirm +via `audiotrace.log` no `ricochet_sounds_small` index fires, and have the +user listen to that clip specifically. If fire+cartridge alone sound correct +and recognizable, close D202 as a repro artifact, not a port bug. Only +resume the envmix/PVoice-identity trace if that clip still sounds wrong. + +## Done this session (M-58) — D202: address/DMA plumbing AND the ADPCM decode math both independently verified bit-exact correct; bug is downstream (envmix/output-routing or PVoice identity), still OPEN + +Picked up exactly where M-57 left off (priority (1): decoded-PCM-per-voice +dump). Extended `GE_MIXERTRACE` (still env-gated, zero cost when unset) to +log DMEM source bytes, ADPCM book coefficients, and the first decoded frame +in `port/src/mixer.c`; added `[DMAREQ]`/`[BINDTABLE]` in +`src/libultra/audio/load.c` and `[DMAHIT]`/`[DMAMISS]` in `src/audi.c`'s +`amDmaCallback` — all four now write into the *same* `mixertrace.log` so one +physical voice filter's whole lifecycle reads chronologically in one file. + +**Made and caught a real mistake mid-session**: first compared +`wavetable->base` from one run's `audiotrace.log` against `aLoadBuffer` +addresses from a *different* run's `mixertrace.log` (separate files, no +shared ordering) and momentarily concluded the mixer never touches the ROM +wavetable data at all — a false alarm from cross-run/cross-file +correlation, not a real bug (per-run nondeterminism, D117, shifts line +counts between runs). Fixed by merging every new probe into one trace file +and rerunning once. Lesson banked in findings.md M-58. + +**With everything in one file, followed soundIndex 46 (the fire SFX) end to +end for one live occurrence:** `BINDTABLE` → `DMAREQ` (memin exactly matches +the bound table's base, no address confusion) → `DMAMISS` (legitimate cold +ROM→staging-buffer copy via `piServiceDma`, a real cart address under +`romdata.c`'s mapping) → `LOADBUF` (dumped the actual ADPCM source bytes) +→ `ADPCMDEC` (dumped the loaded book coefficients, matching `sndPlaySfx`'s +own book pointer for that soundIndex) → `PCMOUT` (dumped the first decoded +16-sample frame). **Hand-decoded the same 9 source bytes against the same +book coefficients using the textbook VADPCM algorithm, entirely independent +of this codebase's code** — first three samples matched the C output +bit-exact (`0, -1536, -2475`). Both the address/DMA plumbing and the decode +arithmetic are now proven correct for this instance, not just internally +self-consistent. + +**This closes the first three links of the pipeline** (request routing — +M-56, DMEM concurrency — M-57, decode itself — M-58). Next session's leads, +in order: (1) trace `aEnvMixer`'s output routing / persistent volume-ramp +state (`sVol`) the same way — one physical voice followed end-to-end in one +trace file — to see if correctly-decoded PCM gets accumulated into the +wrong output/voice; (2) PVoice allocation/identity aliasing higher up in +the synth; (3) only after (1)/(2), the still-dormant `load.c`/`music.c` +pointer-truncation family as its own hardening pass (own D-number).

All three agree. +- Also spot-checked the ADPCM book-coefficient byte-swap (`afFixupBook`, + `romdata.c`) and the `_bnkfPatchWaveTable` pointer math (`bnkf.c`, post-D201 + `uintptr_t`) — both fine, not previously called out explicitly. + +**D202 is still OPEN — root cause not found.** New leading suspect, NOT yet +investigated: the resample/pitch pipeline (`aResampleImpl` + whatever +computes a voice's playback rate from `ALKeyMap`/`unityPitch` — +`synallocvoice.c`/`seqplayer.c`/synport equivalent). A wrong pitch/rate +calc would better explain "sounds like a different sound" (mis-pitched +correct sample) than a literal wrong-sample-content theory, given sample +resolution/pointer-chain tracing already came back clean twice now.

(same session, build+run) — user rebuilt (confirmed no change, +expected) and gave two live-playtest clues that reframe the investigation:** + +1. **The "music-replacement loop" is a real door SFX (`METAL_SLIDE_LOOP_SFX`) + stuck on, not a decode/pitch bug** — confirmed via `GE_AUDIOTRACE` on a + real door interaction (`-level_09`): `sndPlaySfx` legitimately chains + 202→204→203 (open→loop→close, stock N64 chain mechanic in `snd.c`'s + `do…while`). The N64-matching (`//#MATCH`) cleanup code + (`propobj.c door7F053B10()`) that's supposed to stop it looks correct + and isn't a truncated-pointer bug (`door->openSoundState` is already a + real 64-bit `ALSoundState *`). Checked the level-transition "deactivate + all" sweep (`lv.c` → `sndDeactivateAllSfxByFlag_1()`) — it's + flag-filtered (`FINAL_IN_SEQUENCE` only) and wouldn't catch a + mid-chain loop sound even on real N64, so **N64 must instead rely on + the attract-mode demo's scripted input naturally pressing "close door" + before the demo ends.** Leading theory: **this may be a second symptom + of the already-open D193 timing bug** (`g_GlobalTimerDelta`/ + `g_ClockTimer` wall-clock-vs-sim mismatch), not a distinct audio bug — + if the attract demo's fixed-frame-count script runs on a different + real-time schedule on PC, it could get cut off before the scripted + close-door input fires, orphaning the loop voice permanently. **Full + write-up + reasoning chain: `findings.md` D202, "M-53 cont." + the + "Follow-up" paragraph after it.** +2. **"Ammo pickup is one of the knife sounds"** — `PICKUP_AMMO_SFX`=234, + `PICKUP_KNIFE_SFX`=233, adjacent. But combined with PPK(46)→sounds-like- + PUNCH1(47), the two adjacent-index shifts are in OPPOSITE directions — + doesn't fit a simple constant-offset bug. Left open between "two + unrelated single-entry bugs" and "a badly-mispitched correct sample + being misheard as a timbrally-similar neighbor." + +**M-54 — got a live headless repro, and traced the D193-timing theory to a +dead end.** Read `frametiming.c`/`libultra.c`'s VI-retrace/tick chain +end-to-end: the ramrom path bypasses `waitForNextFrame()` and feeds +`updateFrameCounters()` the *recorded* N64 speedframes value directly +(`ramromreplay.c:400`), and the 32-deep `gfxFrameMsgQ` message backlog +self-throttles (each drained burst message after a stall sees near-zero +elapsed and no-ops) — no runaway/duplicate-advance mechanism found. +**Downgrade the D193-linkage theory** — not fully ruled out but the +specific mechanism I'd pointed to isn't there. + +Then extended the `GE_AUDIOTRACE` probes (`snd.c`: `sndPlaySfx` now also +logs `newState=`/`flags=` per chain link, `sndDeactivate` now logs every +call) and used `GE_INPUTSCRIPT="30:A;90:A;...;1170:A;"` (press A once a +second for ~20s to clear the Rare/Nintendo/legal/cast-intro screens fast) +to land in the real attract-mode demo within a ~280s headless run. +**Live repro caught**: the `ramrom_Train` demo plays `TRAIN_GO_SFX` +(soundIndex 64, the only `flags=2`/`SOUND_FLAG_LOOPED` sound in the run) +as two voices — **neither voice ever appears in a `sndDeactivate` line, +anywhere in the log**, while two other, non-looped states DO get +deactivated right as the sequence rolls back to the boot logos. Direct +confirmation of the M-53 "Follow-up" theory: whatever transition sweep +runs there skips looped voices (consistent with +`sndDeactivateAllSfxByFlag`'s `FINAL_IN_SEQUENCE`-only filter). **This +is the same bug as the door report** — any `SOUND_FLAG_LOOPED` voice +started during a `ramrom` demo, not door-specific. + +**New leading theory**: real N64 hardware has a small fixed physical +voice pool with **voice-stealing** (`synallocvoice.c` `_allocatePVoice`, +unchanged decompiled code) — a new sound request silently steals/ramps +out the oldest lower-priority voice once the pool (`maxPVoices`, +unchanged N64 config value) is full, which would eventually silence an +orphaned loop on real hardware even without ever calling `sndDeactivate` +on it. **Not yet checked: whether `port/src/mixer.c` (Phase-3 PC code) +actually enforces the same cap / stealing**, or effectively gives every +voice request a free channel (no stealing ever triggers) — if the +latter, that's the fix, entirely in the port audio layer, no game-logic +(`snd.c`/`propobj.c`/`front.c`) changes needed. + +**Next session, in priority order (superseded by M-55, see above — (a) +and (b) below are now DONE/negative, do not re-audit):** ~~(a) audit +`port/src/mixer.c`'s voice dispatch against `synallocvoice.c`'s +free/alloc/lame-list + stealing algorithm~~ (M-55: mixer.c has no voice +bookkeeping, nothing to fix); ~~(b) look for another explicit N64 +stop-all-ambience call at attract-cycle boundaries~~ (M-55: none exists +on either platform — confirmed absent, not just unlocated); (c) dump +decoded PCM for one mis-sounding SFX via the existing `GE_AUDIOTRACE` +addresses and listen/compare against neighbor entries to settle the +index-vs-pitch question for symptom (a) — **still untouched, now the +top lead**.

Both crashing runs had `GE_PCDUMP` set at high +frame numbers; the clean gdb run had no GE_PCDUMP — weak correlation, unconfirmed. +NOT a regression from #8/#9 (that's what made Linux run at all); `-fstack-protector` +on glibc aborts where MinGW may silently tolerate the same overflow. Windows is +verified crash-free past frame 1740. Candidates: the new POSIX crash/watchdog +path in `port/src/crash.c` (has fixed `char[24]`/`char[64]`/`char linebuf[N][512]` +buffers, `backtrace_symbols` formatting) if it's firing on SIGTERM teardown; or a +real latent in-level overflow.

D157 root cause +`D157` (`src/bondtypes.h`, `#ifdef PORT`): the type-23 objective record's +`MinDificulty` is a BE `s32` at word 3; `d88_propdefs.py` bswap32's it, so on +LE the value moved from byte 0xF to 0xC, but `struct objective_entry.difficulty` +still read `s8`@0xF → **0 for every objective**. `get_difficulty_for_objective()` +returned Agent(0) for all → `objectiveIsAllComplete()` on Agent evaluated +objectives that should be difficulty-gated out (Dam "Neutralize all alarms" = +Secret Agent, "Install covert modem" = 00 Agent) → always incomplete → +`end_of_mission_briefing()` (the unlock write) never ran. **User was right — +you don't shoot an alarm on Agent Dam.** Fixed the struct tail order under +`#ifdef PORT`; also fixed `dump_objectives.py` (same byte-offset bug — it +showed "Agent" for everything). **Next: user replays Dam on Agent (just reach +the exit) under `GE_SAVELOG=1`; expect `MinDif=1/2/2/0` on the crit lines, +`objectiveIsAllComplete=1`, a `fileWriteSave slot=N ... TIMES` line, and +Facility unlocked in mission-select.** If obj 3 (Agent, flag 0x1000) still +shows incomplete, the level isn't setting that stage flag on exit — separate +issue. `GE_UNLOCK_ALL=1` remains the playtest workaround meanwhile. +
+ +
Original M-30 blocker writeup (superseded by D157) +User completed Dam, hit "previous" from the debrief to mission select, +**Facility still locked**. `data/ge007.eep` has zero completion times → the +unlock save isn't landing (or is wiped on reload). Chain: +`bossReturnTitleStage` (`objectiveIsAllComplete()` gate) → +`end_of_mission_briefing` (`briefingpage`/`selected_difficulty` guard) → +`fileUnlockStageInFolderAtDifficulty` → `fileOverwriteSaveSlotWithNewSave` +(needs a slot with `SAVEFLAG_DORESET`) → `fileWriteSave` (`fileGamePakProbe`) +→ EEPROM; then `fileValidateSaves` CRC-checks every slot on menu re-entry and +`fileResetSave`s any mismatch. +**M-30 GE_SAVELOG run 1 (user's gdb.txt) — narrowed:** +`bossReturnTitleStage stage=33` (Dam) fires with **`objectiveIsAllComplete=0`** +→ `end_of_mission_briefing` never called → no unlock write. `fileValidateSaves` +/ CRC / DORESET-slot all fine (first-boot fresh-save init, expected). So the +blocker is **objective-completion detection**: `objectiveIsAllComplete()` bails +at obj 0 (`get_status_of_objective(0) != COMPLETE`). Dam obj 0 = 4× +DESTROY_OBJECT (ALARM tags). This is D126/D151 propDef-decode family — either +`objective->ObjRefID` at the wrong byte offset on LE (criteria records +`_bswap32`'d, `MissionObjectiveRecord.ObjRefID` s32@4 vs the criterion's +`u16` tag), or the `sizepropdef` walk stride is off for a criterion type. +Note `sizepropdef(PROPDEF_OBJECTIVE_START)` PC-branch returns **4** and +`d88_propdefs.py` emits **16 B** for type 23 — but `MissionObjectiveRecord` +(bondtypes.h) is header+ObjRefID+TextID+MinDificulty+`*nextentry` = 20 B N64 +/ 24 B PC. If `nextentry` is real+serialized, both the stride and the +converter are 1-2 words short → whole-stream desync. (`struct objective_entry`, +the other view of type 23, is only 16 B and has no nextentry — the two +structs disagree; the "// maybe wrong..." comment flags it.) +**Diagnostic committed (``):** `GE_SAVELOG=1` now also dumps +each criterion's `type / ObjRefID / TextID / sizepropdef stride / first 3 +words / currentstatus` (gated by `g_savelogObjOnce` so it only fires on the +`bossReturnTitleStage` call, not the per-frame poll). +**Next: user does ONE genuine full Dam completion (all objectives, walk out +the exit) under `GE_SAVELOG=1`; the `SAVELOG: crit ...` lines pin the exact +field/stride that's wrong.** Also noted but not chased: +`fileSetDifficultyStageTime` `offset = ((diff*20)+levelid)*10` indexes +`times[]` up to `[98/99]` but the array is `u8 times[76]` — OOB for +high level/difficulty combos (writes into the next slot's checksum).

Almost certainly the D122/D126/D132 propDef-stride / ROM-serialized-struct-widening family (`struct objective_entry` / the type-23/type-1E setup-text record chain read at the wrong stride on PC). Found in the M-48 Linux level sweep: **5/6 spot-checked levels (`-level_09/20/27/34/37`) load + render fine; `-level_45` is the one failure.** Not a v0.1.0-alpha blocker (alpha is explicitly "expect crashes"). Windows: `-level_45` load status not re-checked this session. | **CLOSED — not a port bug; level 45 is MP-only and has no solo setup file in the ROM (root-caused M-105, reproduced on Windows).** Full chain: `setup_text_pointers[45]` = `"UsetupimpZ"` (`chraidata.c:824`), but that name is **not in the ROM file table** (`assets/obseg/file_resource_table.inc.c`) — only the MP variant `"Ump_setupimpZ"` is. BASEMENT is a 4-player MP level (`front.c:557` `multi_stage_setups[]`, alongside STACK/TEMPLE/COMPLEX/CAVES/LIBRARY — exactly the other missing solo names); MP play prepends `mp_` to the name (`prop.c:1261-1269`), so the solo name was never shipped. A solo `-level_45` boot (debug flag only; no solo mission references stage 45) requests a nonexistent file: on PC the inert rmon stubs (`osReadHost`/`osWriteHost`, `n64stubs.c`) leave the CheckFileExists response in `fileGetIndex`'s dynamic path (`ob.c:421`) **uninitialized** → fresh table entry with size 0 → `fileIndexLoadToBank` allocates bank memory, loads 0 bytes → the setup rebase + propDef walk in `proplvreset2` runs over **stale pool memory** → garbage records (M-105 Windows crash: `modelLoad` via `domakedefaultobj`, `obj=0x784f`; M-48 Linux hit `add_ptr_to_objective` — same garbage walk, different stale contents). N64 parity: the file is genuinely absent there too (indy host answers not-found → index-0 load) — this boot is broken in the original as well. No fix taken: a port-layer guard cannot synthesize a valid setup (the walks need `-1`/`PROPDEF_END` terminators no zeroed buffer provides), and fabricating ROM content for an out-of-scope MP level has no ground truth. The M-48 "Linux-specific" framing was wrong — the failure is platform-independent; it was merely found on Linux first. | -| D191 | **Windows `-O2` release-bundle crash: SIGSEGV in `modelGetNodeRwData` (`src/game/model.c:478`) — the `root->Parent` node-tree walk (M-49, user playtests of the v0.1.0 win64 bundle).** **Two instances, identical fault PC `0x1400801b1`:** (1) fresh save, killed the first guard right after escaping the cell in Bunker ii; (2) Statue (`-level_49`?), right after the Trevelyan meeting cutscene. `ge007.crash.log` (auto-dump; symbols intact in the shipped exe, `addr2line` resolves): PC = `modelGetNodeRwData` at `model.c:478` — the `switch (root->Opcode & 0xff)`, i.e. `root` (a `ModelNode *`) is bad; `addr2line` puts it in the inlined self-recursion at `:532`, so the `while (root->Parent) { root = root->Parent; … }` walk (`model.c:527-540`) handed a garbage node into the recursive call. Instance 1: `Rdx = 0x70267bc000000000` — a `~0x70266xxx` heap address in the **high 32 bits, zero low half** = 32-bit pointer field read as 64-bit (or a byte-swapped `u32` pair). Instance 2: `Rdx = 0`, FAULT ADDR `0x0` — `root` (or `root->Parent`) resolved to NULL. Both: `Rcx=Rdi` = the `~0x7008xxxx`/`~0x7007xxxx` object ptr, `R8 = 0x1d` (29). So the `Parent` chain in some model contains a **truncated or NULL link** — pointer-width / byte-swap family (D3x, D119 `weapons_held[]->chr` type-pun, D122/D126/D132 propDef-stride). NOT weapon-fire-specific — common factor is `modelGetNodeRwData` running on a character/cutscene model whose node tree has a bad `Parent`. Crash logs saved: `scratchpad/crashlogs/`. **Repro aid:** shipped exe has full symbols; `debug-crash.ps1` in the bundle dir runs it under gdb, `GE_D51=1` → `d52rw.log` rwdata-pool trace. The crash.c EBP backtrace breaks immediately (`#01: 0x1d`) — need a real `bt` + `p *root` + `p *Objinst` at the fault. Not yet reproduced under a debugger; no fix. | FIXED + PLAYTEST-VERIFIED (M-79). User replayed Bunker ii (first-guard kill) and Statue (post-Trevelyan cutscene) on the fix build — **both no longer crash** → 21/21 solo levels crash-free (v0.2.0 gate met; Cradle's remaining issue is D193, not a crash). Build clean; bunker1 golden framediff 3/3. **Real gdb backtrace (M-79):** the fault is NOT in the `root->Parent` walk — `root` arrives *already* garbage (`0x70267a9000000000` = a half-word-swapped `u32` `0x70267a90`) from frame #1 `bondviewSelectCuff(model=0x70076808, header=0x700763a0, switchindex=29)`, called from `gunUpdateAndFire(GUNRIGHT)` on the frame the player fires. `bondviewSelectCuff` byte-indexes `header->Switches` (a `ModelNode *` array — **8-byte stride on PC**, widened per D43/D45) with `offset = switchindex << 2` (N64 4-byte stride), so every `base[N]` deref lands mid-slot and yields a misaligned half-pointer that is non-NULL by luck → `modelGetNodeRwData(root=garbage)`. **Exactly the D140 bug class** — D140 fixed the identical pattern in `gunfire.c:1740`; this call site was missed. Fix: PORT-only `offset = switchindex * (s32) sizeof(ModelNode *)`; the `base = (u8*)switches + offset` math and the `#else` N64 line are unchanged. ABI/pointer-width only (D3x class), no game-logic change. The Statue instance (`Rdx=0`, NULL fault addr) is the same site landing on a slot whose bytes read as 0. | -| D193 | **NPC AI locomotion is too slow — characters don't move to their destinations at the original game's rate (M-49, user playtest; clarified after the FULL 21-level playthrough — "the biggest overall flaw").** Not (primarily) an animation-playback bug — the *travel speed* of scripted/AI movement is wrong: guards, named NPCs (Trevelyan, Ourumov) and friendlies (Natalya) all take noticeably longer to run/walk to their goal positions than on N64. General, not chr-specific. **Leading hypothesis — the D117/D134/D155/D156 wall-clock-timing family:** `chr.c` / `chrai.c` integrate movement as `pos += speed * g_GlobalTimerDelta` and step sim loops `while (i < g_ClockTimer)` / `-= g_ClockTimer` (`chr.c:1437,1446,1491-1502,1862,2359,2569`; `chrai.c:76`). On the port `osGetCount()` is free-running wall-clock (D117), `g_GlobalTimerDelta`/`g_ClockTimer` are derived from it, and D155's `FRAMETIMING_PORT_MAX_CATCHUP = 6` clamps `nextFrameTime`. If the effective per-second sum of `g_GlobalTimerDelta` (or the `g_ClockTimer` tick count) runs low — quantization, the catch-up clamp biting during normal play, or a units mismatch (`g_JP_GlobalTimerDelta` vs `g_GlobalTimerDelta`, `chr.c:1435/1437`) — every delta-scaled AI motion integrates slow while **player** movement (input-driven per frame) still feels right, which is exactly the reported split. Related: **D170** (Ourumov/Trevelyan "flee" looks wrong — flagged there as possibly the same locomotion-speed issue rather than an AI divergence). Also possible: `chrGoToBond/Chr(SPEED_RUN/WALK/SPRINT)` speed enum → path-follow step, or pathfinding advancing ≤1 waypoint per frame-quantized tick. **Instances seen (M-49 full playthrough):** (a) Facility — the post-scripted-scene beat with Ourumov + the soldier squad: the soldiers **walk in super slowly and take a long time to path into firing positions** before they start shooting (this is regular squad combat AI, not a named-NPC script — good evidence the slowdown is general delta-scaled `chr` locomotion / path-following, not one ailist); (b) the named-NPC flee behaviour on Silo (Ourumov) and Cradle (Trevelyan) — see D170; (c) **Natalya (the escort NPC) always walks really slow** — on every escort level (Bunker ii, Statue, Control, Archives) she trails far behind, forcing the player to wait. Escort follow-AI is the same `chrGoToChr`/path-follow path as (a). **WORST CASE — Cradle (`-level_51`) is "bugged out completely" due to Trevelyan's behaviour (M-49).** The final level is Trevelyan-fleeing-and-scripted end to end (he runs the antenna cradle, climbs, drops to the cradle floor, the helicopter beat); if his locomotion timing / path-following is off he never hits the trigger points and the level's scripted progression stalls or goes haywire. This makes D193 effectively a **can't-properly-finish-the-game** bug, not just cosmetic sluggishness. **Next:** log `g_GlobalTimerDelta` + `g_ClockTimer` per frame during normal play and check the 1-second sum vs the N64's ~60; time a guard's run across a known distance vs reference footage; then watch Trevelyan's chr state / current AI command on Cradle. | **FIXED + user-playtest-verified (M-81) — root cause is D209**: `act_ubytes.padding[45]`, a raw-byte union alias for `act_gopos.unk59` (the SPEED tier), lands on offset 45 which is `unk59` on N64 but is byte 5 of `waypoints[1]` at 64-bit — always `0x00`. So the locomotion-animation selector `get_sound_at_range()` always received tier 0 and bound `ANIM_DATA_walking`/`walking_unarmed` for **every AI chr in the game**, and since travel is anim-root-motion driven they all moved at walk pace no matter what the ailist commanded. User verified on Cradle: Trevelyan and the guards run. Full elimination trail below — **steady-state timing keystone MEASURED and the "sim sums low" hypothesis is CONTRADICTED (M-80).** Added a `GE_D193=1` per-wall-second probe in `waitForNextFrame()` (`src/game/frametiming.c`, `#ifdef PORT`, env-gated): logs render frames, sim ticks delivered (= sum of the `deltaFrames` fed to `updateFrameCounters` = sum of `g_ClockTimer`), catch-up clamp hits, and max raw pre-clamp delta. Built ntsc-final, ran `-level_09 / _20 / _27 / _34` idle-after-load, ~20 s each. **Every level, rock-steady: render = 30.0 fps, sim = 60.0 ticks/s, clamped = 0, maxraw = 2.** i.e. each rendered frame carries `g_ClockTimer = 2` and the per-second sum is *exactly* the N64's ~60 — the wall-clock timer is NOT running low in steady state, and `FRAMETIMING_PORT_MAX_CATCHUP` never bites in normal play. VSync on/off made no difference (still 30/60). So the B1 premise ("`g_GlobalTimerDelta`/`g_ClockTimer` sum low over a real second") is wrong for the common case; D193 must come from elsewhere. **Residual quantization risk (not yet observed):** `nextFrameTime = (dt_counts + 387937) / 775875` is integer-rounded per frame with no remainder carry, so a scene that renders at a *steady* rate between 30 and 60 that is not an integer divisor of 60 (e.g. a solid 50 fps → dt≈20 ms → rounds to 1 → sim 50/s, ~17 % slow) would under-advance; the fix there is a fractional accumulator in the `#ifdef PORT` path. But the port renders a hard 30 (software RSP ≈ 60 µs/frame — not GPU-bound; the cap is the `pendingGfx < 2` double-buffer + sched round-trip), so this only matters if a real AI-heavy scripted scene drops into the 20–30 band. **Next (needs input, interactive session):** drive Bond into the Facility Ourumov/squad beat (D193a) and Cradle Trevelyan run with `GE_D193=1` — confirm render/sim hold at 30/60 under real AI load; if they do, pivot off timing entirely and instrument a single guard's world position vs. distance/time (anim root-motion rate, `chrGoToChr` SPEED_* enum → step size, path-node spacing) — the travel-speed bug is likely in the locomotion/anim path, not the frame clock. `GE_D193` catalogued in `docs/dev/GE-ENV-PROBES.md`. **M-80 cont. — LIVE-LOAD CONFIRMED, pivot is final.** User ran Cradle (`GE_D193=1`, `-level_41` — see the level-id note below) and drove Bond through the Trevelyan sequence while Trevelyan was visibly "walking really slow". Probe throughout: **`render=30 sim=60 clamped=0 maxraw=2`, dead steady** — no dips, no clamp hits, no `[D156]` guard fires. So under the *exact* failing scene the sim clock delivers a perfect 60 ticks/s. **D193 is NOT a timing/scheduler bug — it is in the character locomotion/animation path.** Best current hypothesis: GE character *travel* is animation-root-motion driven — `modelTickAnim` advances `frame += playspeed*speed` per tick (numticks = g_ClockTimer, correct), then `modelSetAnimFrame2WithChrStuff` (`model.c:3060+`) extracts per-anim-frame translation via `sub_GAME_7F06D3F4(...&pos)` and applies `scale = model->scale * model->anim_translation_scale`. The **player does NOT use anim root motion** (explicit speedgo/speedstrafe physics in bondview2.c), which explains the "player fine / all AI slow" split precisely. Suspects, in order: (1) the anim translation keyframe data is decoded with wrong units/scale by its sidecar converter (D43/model family); (2) `model->anim_translation_scale` or `model->scale` misread (ABI/struct-stride — D3x/D99 class); (3) `model->animrate`/`playspeed`/`speed` wrong. **M-80 cont. — port side instrumented (`GE_D193A` in `chrTick`, `GE_D193B` in `sub_GAME_7F06D3F4`; both `#ifdef PORT`, catalogued in GE-ENV-PROBES.md). Findings:** (i) `g_GlobalTimerDelta = 2.0`, `model->playspeed = 1.0`, `model->scale = 0.1`, `model->anim_translation_scale = 1.0` for every ticked chr on Silo + Facility — the scalars that feed the root-motion accumulation are all nominal, matching the identical N64 C (no `#ifdef PORT` in this hot path bar the non-firing D156 NaN guards). `model->animrate = 0.0` universally but that is the default — only written by `modelSetAnimPlaySpeed` on a blended transition (`startframe > 0`), so not the bug. (ii) Patrolling guards (`act=14 ACT_PATROL`, `model->speed=0.5`) travel **~60–99 world-u/s** on the port — no N64 number to compare against yet. (iii) `GE_D193B` (Facility, walk anim `706af4d8`): the decoded root-motion triple `tmp` ≈ (±0-3, ~1080-1094 hip height, ±0-50) with **`base = 0` and `angle = 0` on every call** (could be legit for a straight-line walk — joint 0 channel A at index 0, no per-frame facing change — or could be a mis-selected/zeroed channel; can't tell without the N64 side). **Bottom line: every port-side input to the locomotion math reads nominal**, so the divergence is either (a) subtle wrong magnitudes in the decoded anim bitstream values themselves (`tmp` triple / the descriptor decode), or (b) something in the `pos34` accumulation / `header->unk*` state — neither visible without a reference. `ModelSkeleton` **ruled out** — the skeletons are statically defined in C (`New_ModelSkeleton`/`MODELSKELETON` macros, `chrobjdata.c` etc.), not ROM-serialized, so `Joints` is a native x86-64 pointer and `ModelJoint` is 6 B on both platforms; `base` is correct. That leaves the ROM-serialized `ModelAnimation` bitstream (`bitDescriptors`/`bitStream`, D32-widened) and the anim-table load path as where a magnitude error could enter. **M-80 cont. — anim-data endianness (D33) audited, looks complete for this path.** `ptr_animation_table` is `romCopy`'d then byte-swapped by `romdataFixupAnimationData` (`port/src/romdata.c`, D33): per 20-byte record it bswaps `+0x00/+0x04/+0x08/+0x0C/+0x0E/+0x10` and per 6-byte `ModelAnimBitField` descriptor bswaps `+0 bitOffset` / `+4 valueOffset` (bitCount/pad identity); the bit*stream* is left raw (correct — `modelAnimReadRootMotionValue` walks it byte-by-byte, MSB-first, endianness-neutral, same as PD's `anim_read_bits`). `PTR_ANIM_walking/running/sprinting` **are** in `animation_table_ptrs1` so guard-locomotion records do get fixed up; `_ptrs2` is only 3 helicopter/plane anims (no overlap → no double-swap). No `bad descriptor range` / `bad record offset` errors in any run. Every `anim->unkNN` the locomotion path reads (`unk04`, `unk06`, `unk07`, `unk0C`) is within the fixed-up 0x14 bytes. `sizeof(ModelAnimation)` = 64 B both platforms (D32 kept the embedded ptrs as `u32`); `sizeof(ModelAnimBitField)` = 6 B both. So the anim decode is structurally sound as far as static review goes — **a magnitude error, if any, needs the N64 reference to see.** **Next — two viable paths (needs a fresh session; toolchain not present here — no `mips-linux-gnu-*`, no `qemu-irix`, no emulator):** (A) set up the MIPS toolchain + IDO-recomp + an N64 emulator with `osSyncPrintf` capture, build the ROM with `#ifndef PORT` `GE_D193B`-equivalent logging, navigate to the same scene, diff `tmp`/`base`/`angle`/travel-speed against the port capture; (B) user records N64 footage (real HW or their emulator) of one guard traversing a measured distance, frame-count it → gives the port-vs-N64 speed ratio (a clean 2× would point at a per-frame vs per-tick doubling; a fractional ratio at a scale/data error). Recommend (B) first — cheap, and the ratio narrows (A) massively. **Highest-impact playtest finding — breaks Cradle.** **Level-id note:** the earlier "Cradle = `-level_51`" in this row and HANDOFF was WRONG — `LEVELID_CRADLE = 41` (`src/bondconstants.h:1662`; STATUE=22, so CRADLE = 22+19). `-level_51` = `LEVELID_EAR` (unused slot) and SIGSEGVs at load in `stanBuildRoomData` (`stan.c:281`, NULL deref) — a non-issue (bad level id), noted here only so it isn't re-investigated as a real crash. **M-81 — SOLVED, and none of the M-80 suspects were the cause.** Re-verified the whole timing chain independently (`waitForNextFrame` -> `speedgraphframes` -> `g_ClockTimer` -> `g_GlobalTimerDelta`; `g_GlobalTimer += g_ClockTimer` at `lv.c:1022` is **tick**-based, so the ~75 AI timeout comparisons against it are frame-rate independent) and re-checked the D33 fixup *widths* against the real structs (they match exactly, and `(bs-bd) % 6 == 0` passing is independent evidence the two embedded pointers decode correctly). Root-motion accumulation is self-consistent (`pos24 = pos34 + rotate(pos)` at `model.c:3322`, so `pos` is a per-frame delta in x/z and an absolute hip height in y — matching the observed `tmp` shape). Extending `GE_D193A` with the visibility-gate counters (`tick`/`move`, i.e. chrTick entries vs `chrUpdateAnim` calls) killed the culling hypothesis too — chr 0 is `31/31` every second. The tier was then shown correct (`tier=1 SPEED_RUN`) and the *animation* wrong (`aidx=40/107`, never 42/41), which is **D209**. Note for future readers: `chrlvApplySpeed`'s `speedPtr` out-param is a **turn** rate, not a travel rate (`chraction.c:8070` passes `&act_runpos.turnspeed` into it), so `act_gopos.speed == 0` just means "running in a straight line" — it is not evidence of a stalled character. | -| D194 | **Mouse input needs another tuning pass — RMB aim over-sensitive + sensitivity couples to frame/sim rate (M-49, user playtest).** Two parts. **(a) Aim mode (RMB) is near bang-bang, not proportional** (`port/src/input.c:697-707`): any per-poll delta past `AIM_MOVE_THRESH` emits stick `m = clamp(61 + |Δ|·(MouseAimSpeed/100)·AIM_GAIN, 61, 60+AimBand)` = `[61,80]` — with the M-29 defaults (`MouseAimSpeed=16`, `AIM_GAIN=4.0`, `AimBand=20`) `m` is already 61 (fast) at ~1.5 px/poll and saturates at 80 by ~30 px/poll, so the usable proportional band is tiny and sits near the top of GE's aim range → "way too sensitive," turn rate barely tracks how fast you actually move the mouse. Needs a real response curve (low floor, wider proportional band, maybe a gamma), not a threshold+clamp. **(b) Overall sensitivity correlates with movement/frame rate** (user's words: "correlated with movement speed, does not feel good"): `input.c` emits raw stick counts **per controller poll** with no `g_GlobalTimerDelta` / polls-per-frame normalization (hipfire yaw `sx += edx·(MouseTurnSpeed/100)·6.0` at `:709`; aim as above). GE integrates the stick scaled by its sim delta, and the port's poll cadence vs render/sim cadence drifts with scene load — so effective sensitivity shifts when the framerate does (which reads as "when I'm moving"). Fix direction: accumulate mouse delta and convert to stick using a fixed reference dt (or feed the game a dt-consistent value), so a given hand motion = a given view rotation regardless of fps. Lineage: D118a (hipfire pitch digital vs analog), D165 (menu pointer), D166 (hipfire pitch pulses), D180-B3 (`MouseAimSpeed` 25→16). New adjacent QoL ask, root-caused → **D223** (mouse-wheel direction should reverse weapon cycle direction, currently both directions cycle forward). Config knobs exist (`Input.MouseAimSpeed/AimBand/MouseTurnSpeed/HipfirePitchSpeed`) but the *shape* of the mapping is the problem. **M-87 design-goal note (user):** overall mouse feel should move toward **Quake Remaster / the Perfect Dark PC port** — raw, direct, responsive 1:1 mouse-look — while explicitly **not losing GE's original aiming nuance** (the analog-stick aim-mode vs digital-hipfire split this whole D118/D194 lineage exists to preserve). Reframes the fix direction from "just widen the proportional band" to: normalize by a fixed reference dt first (part (b), the frame-rate coupling — this alone should fix most of "feels unresponsive"), then re-derive the aim-mode response curve, and treat raw hipfire mouse-look (PD/Quake-style, bypassing the N64 digital-stick emulation entirely when the player is *not* in aim mode) as a real design option to evaluate against "keep GE's aim-mode feel," not assume the N64 stick-emulation path is mandatory everywhere. **M-87 — found it: GE already has exactly this control scheme, unused by the port.** User asked why vertical mouse feels less responsive than horizontal; investigation found the port forces `controldef = CONTROLLER_CONFIG_HONEY` (1.1), under which hipfire pitch is genuinely digital-only (C-up/C-down) while yaw is analog — an intentional N64-era asymmetry (D166), not a port bug, but avoidable. **`CONTROLLER_CONFIG_SOLITARE` (1.2) / `GOODNIGHT` (1.4)** — user's own recollection, verified in code — redirect forward/back/strafe-L/R onto digital C-buttons/D-pad (`bondview2.c:5195-5253`, `moveData.digitalStep{Forward,Back,Left,Right}`), which frees the **entire primary analog stick** for continuous, unclamped pitch **and** yaw: `moveData.canNaturalPitch`/`canNaturalTurn` (set `!insightaimmode`, i.e. active outside aim mode, not gated behind holding aim) drive `analogPitch/70.0f` / `analogTurn/70.0f` directly (`bondview2.c:5950`/`6008`) — no threshold, no digital step, no `[61,80]`-style clamp band (that clamp is specific to the *aim-mode* zoom-turn path, a separate codepath, `insightaimmode && stick_y>60`). `analogPitch`/`analogTurn` default to the primary stick's raw X/Y for every 1.x scheme (`bondview2.c:4881-4882`) unless a 2.x dual-controller scheme overrides them from a second controller. **This is architecturally identical to a modern FPS mouselook**: continuous analog look on the stick, discrete step movement on buttons — a legitimate, unmodified original GE control scheme, not a port invention. Recommended fix: force the port's `controldef` to SOLITAIRE or GOODNIGHT instead of HONEY, map WASD to the digital step-movement buttons (already close to how keyboard hipfire movement works today) and mouse X/Y directly to the primary stick's continuous X/Y — this should resolve the vertical-vs-horizontal asymmetry completely (no more digital-pulse emulation needed at all, D166 becomes largely moot) and likely fixes much of "feels unresponsive" too, since it's direct continuous stick input rather than any thresholded emulation. The frame-rate-coupling issue (part b) is orthogonal and still needs fixing regardless of scheme. Cross-ref D166, D223 (control-preset forcing — this gives a concrete "which preset" answer). **Aim-mode note:** the port's aim-mode code (`input.c:777-784`) already applies the same gain formula to both mouse axes symmetrically — if vertical still feels worse *while aiming* (RMB held), that's a separate, unconfirmed issue, not explained by any of the above. **M-87: user independently confirms part (a)** ("right mouse aim is way too sensitive") and suggests the design fix — aim sensitivity should scale off the **same base per-pixel sensitivity as normal (hipfire-turn) mouse movement**, not its own disconnected curve. Concretely: today hipfire turn is a direct accumulation (`sx += edx·(MouseTurnSpeed/100)·6.0`, `input.c:709`) while aim is the separate floored+clamped `[61,80]` stick-value synthesis (`AIM_GAIN`/`AimBand`, unrelated constants) — two independently-tuned systems that don't agree on what "1 inch of mouse" should mean. Aim mode is a distinct codepath from hipfire (gated by `insightaimmode`, **untouched by the SOLITAIRE scheme change above** — natural-pitch/turn is explicitly `!insightaimmode`), so this needs its own fix regardless of the control-scheme switch. Fix direction: derive the aim-mode mapping from the same base sensitivity constant as hipfire (`MouseTurnSpeed`-equivalent), scaled down only by the aim-zoom's FOV narrowing if any adjustment is wanted at all, rather than the separate `AIM_GAIN`/`AimBand` floor+clamp system — so moving the mouse the same physical distance feels the same whether or not aim is held, without losing GE's own aim-precision character. | **PARTIAL — M-120 human playtest: hipfire/primary look is GOOD now, aim-mode (RMB/Shift) is STILL too sensitive, unusable for precision aiming.** Part (b) (dt-decouple) + the SOLITAIRE natural-pitch scheme switch (part of this PR's combined pass) are user-confirmed working well on PR #62 — normal look feels right. **Part (a) (aim-mode response curve) does not deliver the intended fix despite being "implemented."** User's words: "right mouse / shift aiming with crosshair is still way too sensitive and does not feel right / is not usable in game." Code-level re-read of `port/src/input.c`'s `aimHeld` branch (~line 939) finds a likely concrete cause the original D194(a) design didn't eliminate: `m = AIM_STICK_MIN + pow(normX, gamma) * (AIM_STICK_GAME_MAX - AIM_STICK_MIN)` — the response curve (`aimCurveGamma`, gamma=1.6 default) only shapes the range **above** the `AIM_STICK_MIN=61` floor; the instant `|aimEdx| >= AIM_MOVE_THRESH` (a tiny 0.3 px/poll), stick jumps straight to 61, i.e. **10% of the game's max aim-turn speed (`(stick-60)/10` clamped 1.0), with no ramp from zero.** For hipfire comparison, the non-aim path (`hipEdx * hipSens * MOUSE_TURN_GAIN`, no floor, no threshold-snap) is fully proportional to zero — structurally different, and the one the user says feels good. Aim mode's floor+threshold-snap behavior reads exactly like the original "near bang-bang" M-49 complaint the curve was meant to fix, just now confined to the bottom of the range instead of the top. **Not yet build/runtime-verified** — this is a static code-read hypothesis, not a confirmed root cause; needs an env-gated probe or a tuning pass (e.g., drop `AIM_MOVE_THRESH` toward 0 and make the curve span `[0, AIM_STICK_GAME_MAX-AIM_STICK_MIN]` from a true zero floor, or lower `AIM_STICK_MIN` itself for a genuine near-zero low end) before another playtest. **PR #62 (`fix/d194-mouse-dt-decouple`) stays held, unmerged** — part (a) needs another iteration; parts (b)/SOLITAIRE are ready to land whenever the aim-mode fix is folded in and re-tested together. **M-122: all four stick-synthesis models above were abandoned.** GEPD's own source (`MouseInjectorPlugin/games/goldeneye.c`) was found and read: it never synthesizes a stick for aim at all — it directly overwrites `crosshair_x/y_pos`, `gun_azimuth_angle/turning` (its formulas, RATIOFACTOR=1, basefov) and edge-scrolls the camera past 72% of the way to the screen edge. The port now mirrors that exactly in `port/src/input.c aimGepdCompute()` (knobs `Input.AimAbsolute`, `Input.GepdSens`); no look stick is emitted while aiming, and the game's own damped crosshair update (`caclulate_gun_crosshair_position_rotation`, gunfire.c:4819) is left running — GEPD patches nothing there either, its per-frame overwrite simply wins. **User verdict: "mechanically it works... the aim mode works how we'd want."** Committed `ef49d9e6`. Residuals: ① crosshair/arm spazz glitch, ② aim-mode FPS drop, ③ sensitivity tuning (see M-122 in HANDOFF). **M-123: playtest log (`d194_gepd.err`, 1964 gepdaim lines) mined for ①.** Result: the port's own writes are rock-stable — zero crosshair/camera jumps while aim is held; every large camera delta in the log turned out to be user hipfire stick swings between polls. Exactly ONE true anomaly: a +359° one-tick spike in raw `vv_theta` (cam 0.5 → 359.7, log line 534) — the port's own `[0,360)` wrap of the edge-scroll accumulator firing when the game held a small positive angle and a leftward scroll crossed zero. GEPD does a bare `camx += ...` with no wrap, and the game itself never wraps `vv_theta` in on-foot play (`bondviewApplyVertaTheta` only sin/cos's it; tank code is the sole wraper), so the wrap was removed (port-only). Note: the handoff's theory that this feeds the crosshair via `speedtheta` does not hold — `speedtheta` comes from stick input (`bondview2.c:6056`), never a `vv_theta` delta; all solo-play consumers of `vv_theta` are sin/cos or `(360−θ)` rotations (raw-delta consumers at bondview2.c:1361/9397 are MP-only). The spazz must therefore live in the game-side terms added on top of our overwrite each tick (`turn_x = autoaimx | speedtheta*0.3`, `turn_y = autoaimy | −speedverta*0.1`, gunfire.c:4819 loop) — prime suspect: auto-aim pull oscillating as lock-on jitters, worst near enemies (matches the user's report). The gepdaim log line now also prints the pre-overwrite residue (`game=` = last tick's `pos·damp+turn`), `aa=(autoaimx,autoaimy)`, `st/sv` (speedtheta/speedverta) so a live capture can confirm or kill that. Tick ordering checked: our write runs BEFORE `bondviewProcessInput` each tick (osContStartReadData → inputComputePad, libultra.c:1094), vs GEPD writing after game code — but the displayed fixed point (`X·damp+turn`) is identical either way in steady state, so ordering is not a spazz source by itself. Suspect (c) 2px deadband does not apply to the GEPD path (deadband lives only in the legacy fallback); suspect (d) centre-spring nudge is ~0.1–0.3° over its 2 ticks — negligible, kept (it clears `docentreupdown`, which must not fight aim). **M-123 user playtest (post wrap-fix + extended logging, `GepdSens` 25): "looks good... other than sensitivity we're good, 95%"** — residual arm/gun/crosshair glitching accepted as playable; ① closed as acceptable, remaining D194 work is ③ live sensitivity co-tune (`Input.GepdSens`, ini at 30 at session end) and the still-uncontrolled ② aim-mode FPS retest (logging off). **D194 CLOSED (post-merge):** ③ done (hipfire/aim aligned, defaults `AimModeSens=38`/`MouseTurnSpeed=50`, merged `f239adf5`) and ② resolved by user report -- "no performance [issue] is good now" during the calibrated playtest sessions; the formal logging-off control was never run but the original ≤10fps complaint did not recur, so it is closed on user evidence (revisit only if an FPS regression appears later). | -| D195 | **Transparency / alpha surfaces broken on Control (M-49, user playtest)** — Natalya's console room, the glass partitions + translucent projected wall displays. Originally reported as a blend-state defect. Reinvestigated this session (M-116) after the user reported the glass rendering **solid black** — traced to a real, separate, much bigger bug: `G_TEXTURE_GEN` (RSP environment-mapped texture coordinates, used by shiny/reflective materials game-wide — gold/silver weapon skins, chrome trim, and this glass) was never implemented in fast3d. D72.1 (an earlier session) removed the PD-inherited envmap UV-generation block wholesale to fix the Rareware logo, reasoning "GE never generates texture coordinates from vertex normals" — true for the logo (lit, but does not set `G_TEXTURE_GEN`) but false in general: every envmap draw was left sampling whatever raw `tc[]` happened to be authored (near 0), landing on a fixed corner texel of the reflection map every frame regardless of view angle — for a typically dark-edged reflection texture, a solid near-black surface. | **FIXED (`port/fast3d/gfx_pc.cpp`, `gfx_sp_vertex`) — restored envmap UV generation gated on the real `G_TEXTURE_GEN` bit** (ported from the reference Perfect Dark PC port's already-correct implementation), so D72.1's actual fix is untouched (the logo never sets this bit) while every other envmap draw gets real reflection coordinates. **User-verified live:** console glass and shiny gold/silver guns are now visibly reflective instead of flat black. Confirmed crash-free on a full 21-level sweep. **The remaining "not translucent" complaint is NOT a bug**: user confirmed after seeing the fixed reflective glass that it was never see-through on the original N64 either — it's a reflective (mirror-like) surface by design, not transparent glass. Traced (before the user's confirmation settled it) to the material's own combine formula, `alpha = (TEXEL0/1 LOD-crossfade alpha) * SHADE_alpha + PRIMITIVE_alpha` — an additive constant term that saturates alpha near 1.0 by design, matching "reflective, mostly opaque" intent, not a blend-state defect. **Closed.** Cross-ref: this same envmap fix likely also explains part of D228 (white NPC-weapon patches) if any of those are chrome/shiny weapon variants — worth checking before further D228 investigation. | -| D197 | **Character face/head textures wrap around the head, seen on Silo (M-49, user playtest).** Reads as `G_TX_CLAMP` not honoured (or a non-power-of-two wrap period) on a head/face texture tile — the texture repeats around the mesh instead of clamping at the UV edge. Not yet isolated to a specific character or texture; no `GE_PCDUMP`/`GE_TEXDUMP` capture taken. Likely fast3d texture-tile setup (clamp/wrap mode bits from the tile descriptor not round-tripped) rather than a data bug, given it's cosmetic and geometry-independent. **Next:** `GE_TEXDUMP` the offending head texture's tile descriptor on Silo, diff clamp/mirror bits against `gmain.s`'s expectations for that material. **v0.2.0-pre playtest (user):** no longer observed on Silo — closed, dropped from release known-issues. | CLOSED — user playtest v0.2.0-pre | -| D198 | **`alAdpcmPull`/`_decodeChunk` used `K0_TO_PHYS` (an unconditional `& 0x1FFFFFFF` mask) on 64-bit heap pointers (`src/libultra/audio/load.c`).** `K0_TO_PHYS` is the N64 kseg0→physical mask, valid only because N64 pointers fit in 32 bits; on PC's 64-bit heap it truncates any pointer whose value exceeds 512MB, corrupting the `aLoadADPCM`/`aSetLoop`/`aADPCMdec` DRAM addresses at 3 call sites (`load.c:71`, `:468`, `:474`). Every sibling call site in `env.c`/`resample.c`/`reverb.c` already resolves state pointers via `osVirtualToPhysical` (the port shim, `port/src/libultra.c`), which is bit-identical to `K0_TO_PHYS` for real N64 kseg0 addresses but correctly PC-shimmed. **Fix (ABI-layer, `#ifdef`-free — same call resolves correctly on both platforms):** replace the 3 `K0_TO_PHYS(...)` calls with `osVirtualToPhysical(...)`.

GE uses the classic IDO libaudio ABI (verified against every call site in `src/libultra/audio/*.c` + `src/libultrare/audio/{env,reverb}.c`), not PD's differently-shaped "naudio New" ABI — DSP math (ADPCM decode, linear resample, linear envelope mix) is the same Nintendo/SGI ucode PD's `mixer.c` already ported; only the ABI/addressing layer is GE-specific and new here. Several opcodes (`aADPCMdec`, `aResample`, `aEnvMixer`, `aLoadBuffer`, `aSaveBuffer`) take only a state/DRAM pointer — their DMEM source/dest addresses and byte counts come from the most recent `aSetBuffer` call(s), which there is no RSP disassembly to check against; the persistent-context shape (`sCtx.{in,out,count,dryR,wetL,wetR}`) was reconstructed purely from reading every `aSetBuffer`+opcode call-site pair across `resample.c`/`load.c`/`reverb.c`/`mainbus.c`/`save.c`/`env.c` (see the field comments on `sCtx` in `mixer.c:52-82`). `aSegmentImpl` is a no-op — GE's audio DRAM addresses are already resolved via `osVirtualToPhysical` before reaching the mixer (see D198), so segment/base never factor into DMEM addressing here. **Risk:** the `aSetBuffer` context reconstruction is an inference, not a verified spec — if a call site this session didn't audit sets the context differently, audio for that path will mix from the wrong DMEM offsets. **Verified:** `-level_09` now runs full music + SFX 120s+ crash-free (post-D200 fix); no cross-level or opcode-level audio-correctness verification done yet (no golden-audio comparison tooling exists). | LANDED (`port/src/mixer.c`, `port/include/mixer.h`, `include/PR/abi.h`) — functional on `-level_09`, context-inference risk noted, needs a wider level sweep | +| D187 | **HUD ammo-type/weapon icon vanished at `-O2` (M-46 root-cause, M-47 fix + verify).** — full `## D187` entry at file tail | FIXED (`src/game/gunfire.c`, `#ifdef AVOID_UB`); PR #19 | +| D188 | **Linux `-O2` boot crash: `_Printf` passes `&args` of a by-value `va_list` param (M-48).** — full `## D188` entry at file tail | FIXED (`src/libultrare/libc/xprintf.c`, `src/sprintf.c`, `#ifdef PORT`); PR #22 | +| D189 | **Linux `-fstack-protector` aborts on the decomp's latent stack-buffer overruns (M-48) — FIXED.** — full `## D189` entry at file tail | FIXED (`CMakeLists.txt`, `src/game/stan.c` `#ifdef PORT`); PR #23 | +| D190 | **Linux `-level_45` SIGSEGV at load in `add_ptr_to_objective` (`objective.c:64`) (M-48, open).** — full `## D190` entry at file tail | **CLOSED — not a port bug; level 45 is MP-only and has no solo setup file in the ROM (root-caused M-105, reproduced on Windows).** Full chain… | +| D191 | **Windows `-O2` release-bundle crash: SIGSEGV in `modelGetNodeRwData` (`src/game/model.c:478`) — the `root->Parent` node-tree walk (M-49, user playtests of the…** — full `## D191` entry at file tail | FIXED + PLAYTEST-VERIFIED (M-79).… | +| D193 | **NPC AI locomotion is too slow — characters don't move to their destinations at the original game's rate (M-49, user playtest; clarified after the FULL 21-level…** — full `## D193` entry at file tail | **FIXED + user-playtest-verified (M-81) —… | +| D194 | **Mouse input needs another tuning pass — RMB aim over-sensitive + sensitivity couples to frame/sim rate (M-49, user playtest).** — full `## D194` entry at file tail | **PARTIAL — M-120 human playtest… | +| D195 | **Transparency / alpha surfaces broken on Control (M-49, user playtest)** — full `## D195` entry at file tail | **FIXED (`port/fast3d/gfx_pc.cpp`, `gfx_sp_vertex`) —… | +| D197 | **Character face/head textures wrap around the head, seen on Silo (M-49, user playtest).** — full `## D197` entry at file tail | CLOSED — user playtest v0.2.0-pre | +| D198 | **`alAdpcmPull`/`_decodeChunk` used `K0_TO_PHYS` (an unconditional `& 0x1FFFFFFF` mask) on 64-bit heap pointers (`src/libultra/audio/load.c`).** — full `## D198` entry at file tail | FIXED (`src/libultra/audio/load.c`) — part of the Phase-3 mixer landing, not yet build/runtime-verified in isolation | +| D199 | **Phase-3 software audio mixer: macro-swap `aXxx` opcode execution + reverse-engineered `aSetBuffer` persistent-context semantics (`port/src/mixer.c`…** — full `## D199` entry at file tail | LANDED (`port/src/mixer.c`, `port/include/mixer.h`, `include/PR/abi.h`) — functional on `-level_09`, context-inference risk noted, needs a wider level sweep | | D200 | **`-level_09` segfault: reverb's `ALDelay.input/output` are u32 — `-d->output` zero-extends to a +4GB pointer offset on 64-bit (D3x class, FIXED).** `src/libultrare/audio/reverb.c` back-references the delay ring as `&r->input[-d->output]`; on N64 (s32 `ptrdiff_t`) the u32 negation wraps to a small negative index, on PC x86-64 it zero-extends to +4294967136 samples → `_loadBuffer`/`_saveBuffer` write 13–52KB wild, trampling the delay array / `r->base` / adjacent heap in a self-propagating loop until unmapped memory.

Open F10 overlay → `optionsOverlayToggle()` (`optionsoverlay.c:391`) calls `inputSuspendForOverlay()` which forces `SDL_ShowCursor(SDL_ENABLE)` + drops the grab. While open, `inputComputePad(0)` early-returns at `input.c:512` (overlay owns controller 0) **before** `reconcileGrab()` / any cursor-visibility call. On close: the next poll runs `reconcileGrab(menuMode)` (`input.c:522`) which re-grabs + hides the cursor **only if `captureArmed && !menuMode`** — i.e. only if you had already clicked-to-lock in a stage before opening F10. If you opened the overlay from a menu, or in a stage you hadn't clicked-locked yet, `want` computes 0, `mouseGrabbed` stays 0, and **nothing calls `applyCursorVisibility()`** — so the cursor `inputSuspendForOverlay()` made visible never gets re-hidden (correct free-but-focused state per `applyCursorVisibility()` `input.c:842-846` is *hidden*). **Fix (port-only, ~1 line):** call `applyCursorVisibility()` right after the `reconcileGrab(menuMode)` at `input.c:522` (self-heals every poll once the overlay-open early-return stops firing), or add an `inputResumeFromOverlay()` that runs `reconcileGrab` + `applyCursorVisibility` and call it from `optionsOverlayToggle()` on close. D180/D184/D165 input lineage. Minor. | **FIXED (`6e758f1d`, merged to `main`) — the first option above was applied:** `applyCursorVisibility()` now runs right after `reconcileGrab(menuMode)` in the controller-0 poll, so once the overlay-open early-return stops firing the cursor visibility self-heals on the next poll.

It now reproduces: with `MouseCaptureMode=0` the menu pointer runs the relative-delta P-controller path (`port/src/input.c:659-690`), which clamps target+estimate to `getPlayer_c_screen*` — but that accessor returns `g_CurrentPlayer->c_screenwidth` (`src/game/bondview.c:882`), which in the front end is the ~320×240 stage viewport, **not** the front end's actual 440×330 (`front.c:8570` `viSetViewSize(440,330)`). So the effective clamp is still ~300/220 while the mission-select grid's outer split points sit at 317 / 235.5 (`front.c:516/519/3180/3194`) — outer columns + bottom row unreachable, P-controller winds up and never settles. `MouseCaptureMode=1` (the shipped default, click-to-lock) writes `cursor_h_pos`/`cursor_v_pos` directly from the absolute OS cursor (`input.c:629-657`) and *feels* fine, though it shares the bad `hiH` so the last few px at the right/bottom edge may still be short. **Not a v0.1.0 blocker** — default mode is acceptable, always-grab is opt-in via INI, front-end roughness is already in the release notes. **Fix (port-only, small):** in the `menuMode` branch, when `current_menu` is a front-end menu use the real front-end rect (hard-code `front.c`'s cursor clamp `[20,420]×[20,310]`, or read the front-end viewport global) instead of routing through `g_CurrentPlayer`. Confirm with one `GE_INPUTLOG=1` capture in mission-select — sweep the mouse to each corner, watch where `cursor=(x,y)` plateaus. D165 · D169 · D180 lineage. | CLOSED — the buggy mode 0 was removed entirely in the v0.2.0 prep pass (see D239); click-to-lock is now the only capture mode, so the unreachable-cells path no longer exists | -| D221 | **SELECT FILE screen: the mouse hit-box for a file slot is vertically offset from its visible box — you have to click *below* a file to select it, hovering directly over it doesn't (M-87, user QA, default `MouseCaptureMode=1`).** Different symptom from D192 (D192 is an unreachable-outer-cells *clamp range* bug under legacy mode 0; this is a per-row hit-test/highlight *offset* bug under the shipped default mode 1). | **FIXED (M-91) — root cause was NOT a coordinate/origin mismatch: it's a compiler stack-layout dependency in `interface_menu05_fileselect` (`front.c`).** The hit-test projects each wallet's model extents via `projectRectCornersTo2D`, which takes `{min,max}` `coord2d` *pairs* — but the file-select caller passed `&xmin, &ymin` (four separate f32 locals), relying on the N64 compiler laying out the max adjacent to each min. On PC (declaration-order locals) `arg1->f[1]` reads **ymax** as an X coordinate and `arg2->f[1]` reads an unrelated stack float (observed: `2.25734`, later `nan`) — so the vertical hit band collapsed to a ~14 px strip at the bottom edge of each wallet, sometimes NaN (never selectable that frame). Exactly "click below the file." The other caller (`objective_status.c:525`) passes real `coord2d` structs and was always fine. Fix: pass explicit `{xmin,xmax}`/`{ymin,ymax}` pairs under `#ifdef PORT` (identical values to what the N64 binary used; N64 path untouched). Verified headless: pre-fix A-press at cursor (154.7,127.8) over folder 0 never selected; post-fix same press selects folder 0 and advances. **Human mouse-playtest (this session): confirmed clicking directly over each visible file wallet selects it immediately, no aiming low required; consistent across all slots and the Copy/Erase icons; no crash.** Full details in §H "D221 — M-91". | -| D222 | **High `Video.FovScale` breaks culling — NPCs and some world objects stop rendering near the screen edges (M-87, user QA).** Split out of D211's noted residual: `currentPlayerSetCameraScale()` / the game's frustum-cull and screen↔world math still run at the **nominal, unscaled** fovy while the actual render projection is widened by `portFovScale` (`fr.c:737`) — so objects that are on-screen in the widened view but outside the nominal-FOV frustum get culled before they reach the renderer. Confirmed **not cosmetic** — a real, noticeable functional regression at high FovScale, not just "culls a hair early." | **FIXED, awaiting visual verification (M-121).** Root cause traced one step further than the original write-up: `currentPlayerSetCameraScale()` (`game/bondview.c`) derives both the frustum-cull plane normals (`c_cameratopnorm`/`c_cameraleftnorm`) *and* the fog/LOD distance-visibility-fade scale (`c_scalelod`/`c_lodscalez`, consumed by `chrobjFogVisRangeRelated()` et al. in `propobj.c`) from `c_perspfovy`, which every `viSetFovY`/`viSetAspect`/`viSetFov`/`viSetZRange` call in `fr.c` was setting from the **nominal** `g_ViBackData->fovy` — never the `portFovScale`-widened value D211 already computes for the actual render projection two lines away in `viSetupCurrentPlayerView`. Fix: factored the existing widen-FOV math out of `fr.c` into `f32 portScaleFovY(f32 fovy, s32 isTitleScreen)` (`port/src/video.c`, D222 — identical logic, same `LEVELID_TITLE` guard, no game-code duplication) and fed it into all 4 `currentPlayerSetPerspective()` call sites via a small `#ifdef PORT` local helper in `fr.c` (`frCullFovY`), same as the existing D211 projection-matrix chokepoint now also calls the shared helper instead of its own inline copy. Identity (bit-for-bit no game-code-visible change) at `FovScale=100` by construction — `portScaleFovY` returns `fovy` unchanged whenever `portFovScale == 1.0f`. Audited per the original risk note: `c_cameratopnorm`/`c_cameraleftnorm`/`c_scalelod`/`c_lodscalez` are consumed only in `propobj.c`'s fog-visibility-fade math and `bondview.c`'s own screen-space transform — no AI-visibility/awareness call sites found reading these fields, so `portFovScale` still only touches rendering-adjacent visibility, not NPC behavior. Rebuilt clean, crash-free at `FovScale=150` on `-level_33` (Dam). `bunker1` golden framediff was inconclusive in this dev box — the *unmodified* baseline build also fails it by a similar or larger margin (confirmed via an A/B stash/rebuild), matching the documented pre-existing frame nondeterminism (`porting-notes.md` §E), not a regression from this change. **Needs a human's eyes**: does high-`FovScale` screen-edge NPC/object culling actually look fixed now. | -| D223 | **QoL ask: mouse-wheel weapon cycling should be directional like a normal PC shooter — wheel up = next weapon, wheel down = previous — instead of both directions cycling forward (M-87, user QA).** **Root-caused, port-only fix, no game-logic change needed** — GE's engine already has separate forward/backward weapon-cycle signals: `bondview2.c` computes `moveData.weaponForwardOffset = edge(invButtons) && !(shootButtons held)` and `moveData.weaponBackOffset = (invButtons held) && edge(shootButtons)` (`bondview2.c:5338-5347`, the classic N64 "hold A, tap Z to cycle backward" trick). Default control scheme (the `else` branch used unless a Domino/Goodhead/Galore/Plenty preset is active, `bondview2.c:5177-5179`): `invButtons = A_BUTTON` (= port `GE_CONT_A`, `input.c:86`), `shootButtons = Z_TRIG` (= port `GE_CONT_G`, `input.c:88`, the fire button). `moveData.triggerOn` is explicitly suppressed while `invButtons` is held, so holding A never causes an accidental shot when the Z edge lands. The port's `inputPostWheel()` (`input.c:977`) currently does `if (notches < 0) notches = -notches` — **discards wheel direction** — and only ever synthesizes a bare `GE_CONT_A` pulse (`wheelPulse`, `input.c:631-634`), i.e. always "forward." | **FIXED (M-105, `port/src/input.c`) — directional wheel cycling implemented per the plan below.** Wheel-up keeps the existing 2-poll `A` pulse (`weaponForwardOffset`: fresh A edge, Z released). Wheel-down runs a 2-poll backward sequence: poll 1 presents `A` only, poll 2 presents `A`+`Z_TRIG` — the fresh-Z-edge-while-A-held combo `weaponBackOffset` requires (`bondview2.c:5337-5340`); ordering matters because the edge is computed against the game's own previous poll. `moveData.triggerOn` (`bondview2.c:5419`) requires A to be released, so the synthesized Z edge can never fire a shot. Roles are stable: the port forces `CONTROLLER_CONFIG_HONEY` (`bondview.c:1484`), whose scheme gives `invButtons=A_BUTTON`/`shootButtons=Z_TRIG` — the same roles the pre-fix forward pulse already relied on. Known limitation (pre-existing, not a regression): while RMB aim is held the game flips `controldef` to KISSY (`bondview2.c:6106-6112`), under which *neither* direction cycles — exactly as the old forward-only pulse behaved in that state. Owes a human play-test (wheel up = next weapon, wheel down = previous, no accidental shots). Plan: keep `wheelPulse` (or a new `wheelPulseFwd`) for wheel-up as today; add a `wheelPulseBack` path for wheel-down that instead holds `GE_CONT_A` across ≥2 polls while presenting a fresh `GE_CONT_G` edge partway through (mirroring the invButtons-held + shootButtons-edge combo) — sequence matters (A must already read "held" `oldbuttons`-wise before G's edge, per `weaponBackOffset`'s check order). Must confirm which N64 control preset (`controldef`) the port's save data actually carries — `invButtons`/`shootButtons` differ under KISSY/GOODNIGHT/SOLITARE/etc; if the port doesn't force one, the synthesized combo needs to match whatever's active, or the port should just force the default (HONEY-equivalent) preset since its own `Input.Bind` system already replaces N64-style scheme selection. Port-only, `#ifdef PORT` in `input.c`, no `src/` game-logic touch. **M-87: PD-PC-port precedent checked (user asked what PD did about N64 control presets).** PD does **not** route mouse/gamepad through the N64 preset system at all — it defines its own logical control-key layer (`CK_*` in `port/src/input.c`/`input.h`, e.g. `CK_DPAD_L`/`CK_Y`) fully decoupled from the N64 controller-config enum, and even treats mouse-wheel-up/-down as **two independent bindable virtual keys** (`VK_MOUSE_WHEEL_UP`/`_DN`, defaulted to distinct `CK_*` actions) rather than one "wheel = cycle" event — exactly the shape of the fix this row wants. PD's `controldef` field is hardcoded (`player.c`/`playermgr.c` `controldef = 2`), not left to the original in-game control-style picker. **This GE port already has the equivalent layer for this purpose: D214's `Input.Bind` system.** Recommendation for D223 (and the user's broader ask — N64 presets aren't meaningful for mouse/keyboard, and modern-gamepad (Xbox/PS) support should be a first-class port concept, not routed through N64 presets either): add two new `Input.Bind`-able logical actions (e.g. `IA_WEAPON_NEXT` / `IA_WEAPON_PREV`) that synthesize the invButtons/shootButtons combos under the hood, default-bound to wheel-up/-down (keyboard/mouse) and left open for a future bumper/shoulder-button default under real gamepad support; and have the port force a single fixed `controldef` (matching PD's approach) so the synthesis target never depends on the original N64 control-style menu. That menu itself becomes a candidate for hiding/no-op in a future QoL pass once `Input.Bind` fully supersedes it — not proposed as a change here, just noted as the natural conclusion. **M-87 — D194 gives a concrete answer for *which* preset: `CONTROLLER_CONFIG_SOLITARE` (1.2).** It's the scheme that gives free continuous full-stick mouselook (see D194) — and conveniently, `SOLITARE` is **not** in the `KISSY`/`GOODNIGHT` button-role group (`bondview2.c:5168-5179`), so it keeps the **same** `shootButtons=Z_TRIG`/`invButtons=A_BUTTON` roles this row's plan already assumed — no change needed to the wheel-cycle synthesis. (`GOODNIGHT` (1.4) also gets natural pitch/turn but groups with `KISSY` for button roles — `shootButtons=A_BUTTON`, `invButtons=L_TRIG|R_TRIG` — so it would need this row's combo re-derived; prefer SOLITARE unless something else needs GOODNIGHT specifically.) **M-87 survey note, filed for later (candidate 4, no action needed now):** GE's port has no per-player control-*mode* concept — keyboard/mouse is always controller 0 (`inputOpenPads()`, `connectedMask=0x1`), covering the common "P1 mouse+kb, P2+ pads" local-MP case fine. PD adds a 5th per-player control-mode entry ("PC controls") with a save-compatibility shim (written as an existing N64 mode so the save format never changes, overridden back to PC mode on read by config) to let *any* player be on mouse+keyboard, not just P1. Only relevant if "P1 on pad, P2 on keyboard" (or more than one keyboard player) is ever a real ask — bigger feature than anything currently planned; not worth a Dxx yet. | -| D224 | **QoL gap (M-87, from a PD-PC-port survey): the N64 Rumble Pak is fully dropped instead of modernized.** GE genuinely has a rumble subsystem (`src/motor.c`, `src/joy.c`) but the port's `osMotorInit/Start/Stop` (`port/src/libultra.c:1220-1223`) are all hard stubs — "no accessories on the PC," `osMotorStart`/`osMotorStop` return `-1` unconditionally, `osPfsFindFile`-family returns `PFS_ERR_NOPACK`. So every in-game rumble event (weapon recoil, explosions, etc.) computes and calls into a dead path. **PD's PC port wires the equivalent straight through to real gamepad rumble:** `inputRumbleSupported(idx)` checks `SDL_GameControllerHasRumble`/`SDL_JoystickIsHaptic` (with a Windows fallback: some pads report no haptics but rumble anyway), `inputRumble(idx, strength, time)` calls `SDL_GameControllerRumble()` scaled by a per-pad `RumbleScale` config value (options-menu slider, `Input.PadN.RumbleScale`), and `osPfsFindFile` reports a "Rumble Pak" present exactly when a real pad supports rumble (`libultra.c` — same "pretend the N64 accessory is there" pattern GE's port already uses for `osMemSize`/Expansion Pak, just applied to a real capability instead of faked). Cross-ref `QOL-INVENTORY.md` (folded into the existing "per-pad tuning" row). | **DEPRIORITIZED (M-87, user call).** Gamepad-only — irrelevant to mouse/keyboard, which is the primary target for this next release; no keyboard/mouse play is affected by NOT doing this. Root cause + fix still valid whenever gamepad support becomes a priority (no `src/` game-logic touch: GE's `motor.c`/`joy.c` call sites already exist and already call the `osMotor*` shims; the fix is entirely in `port/src/libultra.c` + `input.c` — add `inputRumbleSupported`/`inputRumble` per the PD shape, wire `osMotorStart`/`osMotorStop` to them, add `Input.PadN.RumbleScale` config). **M-87 PD-legacy-survey addendum (`docs/dev/notes/PD-LEGACY-SURVEY.md` candidate 1, high confidence) — the D224 fix as originally stated is NOT sufficient by itself.** Two more upstream blockers sit before the stubbed `osMotorInit/Start/Stop` ever gets reached: (1) `port/src/libultra.c:1096-1098` sets `g_contStatus[i].status = 0` for every pad — `CONT_CARD_ON` is never set, and `src/joy.c:184` gates the *entire* rumble-pak init path on that bit, so `joyRumblePakInit()` never even calls `osPfsInit`. (2) `src/joy.c:186-190` only attempts `osMotorInit` if `osPfsInit`'s return is `PFS_ERR_ID_FATAL` or `PFS_ERR_DEVICE` — but the port's stub (`libultra.c:1214`) returns `PFS_ERR_NOPACK`, so motor init is never attempted even once (1) is fixed. PD's exact trick (`libultra.c:213-227,349-351`): set `CONT_CARD_ON` for connected pads, and make `osPfsInitPak()` return `PFS_ERR_DEVICE` specifically when the pad supports rumble. **Whenever D224 gets implemented, both of these must land alongside the `SDL_GameControllerRumble` wiring** or the game's state machine parks at `RUMBLEPAKINITSTATE_NOT_READY` forever and nothing audibly changes despite looking wired up correctly. | -| D225 | **Dev-tooling QoL (M-87, user ask): a debug-build/env toggle that unlocks all missions + all cheats, for testing.** Root-caused a clean single choke point — **both** gates route through the same function: `bool fileGetIsCheatUnlocked(save_data *save, s32 cheat)` (`src/game/file2.c:391`) reads the save's `unlocked_cheats_1/2/3` bitfields and returns whether bit `cheat` is set. Mission-select lock (`src/game/file.c:59`, gates whether a briefing page's mission is selectable) and the cheat-menu availability check (`frontCheckIfCheatIsUnlocked`, `front.c:1009`, itself calling `fileGetIsCheatUnlocked` for the per-level `SP_LEVEL_*` cheat IDs) **both** call it — it's a pure, side-effect-free bitfield read (no save-data mutation), so short-circuiting it to always-true under a debug env var unlocks mission-select *and* the cheat menu in one change, matching exactly what was asked ("those two go a long way"). **Bonus, free once cheats unlock:** the ROM already contains real Rare-era developer cheats that are otherwise unreachable in normal play — `CHEAT_LINEMODE` (wireframe render — would make D222-style culling bugs trivial to see), `CHEAT_BONDPHASE`, `CHEAT_DEBUG_POS`, `CHEAT_DEBUG_UNK5` (`cheat.c` ~L687-707, `CHEAT_MASK_GLOBAL`) — worth trying once this lands, may be useful dev tools in their own right. | **OPEN — root-caused, not implemented.** Plan: `#ifdef PORT`, env-gated (e.g. `GE_DEBUG_UNLOCKALL=1`, catalogue in `GE-ENV-PROBES.md` once added) short-circuit at the top of `fileGetIsCheatUnlocked` — `if (getenv-cached-flag) return TRUE;` before the bitfield read. Default off ⇒ zero behavior change for normal play; when set, purely a query-time override (save file itself is never touched, so it can't corrupt a save or leak into the shipped default). No `src/` logic change beyond the guarded early-return (same class of edit as other `#ifdef PORT` dev-convenience hooks, e.g. `GE_STARTMENU`). | -| D226 | **QoL ask: player-adjustable HUD scale for the ammo counter, bottom-left pickup/item status text, and top-of-screen dialogue/subtitle text.** All three route through the same primitive, `textRenderOutlined()` (`src/game/textrelated.c:688`, doc comment: *"Used for ammo counter, bottom left HUD messages, countdown timers"*), called from two specific in-game (not menu) sites in `bondview2.c`: **ammo + bottom-left pickup/status** at `bondview2.c:10005` (`stringbuffer_lowerleft[...]`, anchored at `view_left`/`view_vert`), and **top-of-screen dialogue** at `bondview2.c:10163`/`10165` (`stringbuffer_top[...]`, anchored at `msg.x`/`msg.y`). `textRenderOutlined` → `textDrawGlyphQuad` (`textrelated.c:615`) emits each glyph as a plain RDP `gSPTextureRectangle` at the glyph's native font-metric pixel size, `dsdx`/`dsdy` = `0x400` (1:1 texel:pixel, no scale factor anywhere in the call chain). Same function is also used by menus/options/multiplayer UI (`front.c`, `options.c`, `mpmenu.c`) — **do not scale generically**, those have their own layout at fixed screen fractions and D211 already established HUD anchors must stay put; scale only the 3 in-game HUD call sites named above, about their existing anchor (so bottom-left stays bottom-left, top stays top — same anchor-preserving principle as D211's HUD-static check). | **OPEN — root cause / call sites identified, not designed or implemented.** Two viable directions: (a) a `#ifdef PORT` wrapper at just these 2-3 `bondview2.c` call sites that scales the emitted `gSPTextureRectangle` geometry (`xl/yl/xh/yh`) by a new `f32 portHudScale` (default 1.0 ⇒ byte-identical) while inversely scaling `dsdx/dsdy` to keep the same source glyph texels mapped onto the larger/smaller rect, re-anchored so the opposite edge (bottom for the lower-left block, top for dialogue) doesn't move; or (b) thread a scale parameter into `textRenderOutlined`/`textDrawGlyphQuad` itself, defaulted to 1.0 at every other call site. (a) is more surgical (matches the "don't touch shared menu text" constraint) but duplicates a little geometry math; (b) is more central but touches a much more widely shared function. No PD precedent found (PD's port has no equivalent HUD-scale option). F10 overlay slider candidate once implemented, alongside `Video.FovScale`. | -| D227 | **Sky renders as two independently-moving halves — reads as "two sky processes" (M-93, user QA on PR #43's debug build, `-level_22` Statue and Cradle).** Each half of the screen shows a different sky pattern, and the two halves scroll/move at different rates relative to each other. Surfaced *while* verifying D176(a)'s perspective-correct-interpolation fix — D176(a)'s fix measurably improved the scroll-speed symptom on the visible pattern but did not touch this; this is a distinct defect, not a regression from that PR (unclear yet whether it pre-dates PR #43 or was merely easier to notice once the scroll speed calmed down enough to see the seam). User flagged one confound worth ruling out first: might be a widescreen/aspect-ratio artifact of rendering at modern resolutions rather than a logic bug — original N64 output is 4:3/{something narrower}, and the sky-quad tiling math (`skyPortRenderPoly`, `sub_GAME_7F097388` upstream) may assume the original screen split. | **FIXED (M-100b, PR #43) — root cause was a unit error, and it also fixed the "sky scrolls too fast" complaint (M-96) and the over-tiling.** `unk20`/`unk24` are already in the RDP's native S10.5 1/32-texel units; M-82 read them as texel counts and baked `tc = (S - fold) * 32`, making every sky texcoord 32x too large and overflowing the `s16` `tc`. Human play-test confirmed by the user on the previously-failing levels. Full write-up: §H "D227 — M-100b". Historical investigation trail below. **OPEN — visual evidence captured + a concrete mechanistic hypothesis found (M-94), not yet fixed.** Headless `-level_22` capture confirms a real, visible crease/discontinuity in the cloud texture — not a rendering artifact of viewing it live, and present in a single static frame (rules out the "just camera pan" explanation for at least this instance). Screenshot: `docs/img/bugs/d227-sky-seam-statue.png`. **Leading hypothesis:** `skyPortRenderPoly` (D176(a)'s fix) computes `wScale` per call — i.e. per individual triangle in the sky fan (`skyRenderTri`/`skyRenderFull` issue up to 5 separate `skyPortRenderPoly` calls per frame from a 5-vertex fan, `sky.c:900-920`/`1372-1393`) — from that triangle's own 3 vertices' `unk0c`. The position math is exact for any `wScale` (verified algebraically: `clip.x = (ndcX·w/wScale)·wScale = ndcX·w` regardless of `wScale`), so this is not a logic bug in the fix itself, but the `s16`-quantized `ob[]` storage means each triangle's shared-edge vertices get **independently re-quantized at a different granularity** depending on that triangle's own `wScale` — a vertex sitting on the seam between two triangles can round to a measurably different `ob[]` value in each triangle's independent call, producing a small position/continuity crack exactly at triangle boundaries. This would read as "two adjacent regions with different patterns" without requiring two draw calls or two cloud layers — one `skyPortRenderPoly` call producing a slightly different quantization per neighboring primitive is sufficient. **Not yet confirmed** — did not isolate camera motion from sky-scroll motion cleanly enough to independently verify the "each half moves at a different rate" part of the user's report, only the static crease. **M-95: FIXED (the static-crease part) + headless-verified.** Implemented the fix direction above: `skyPortBeginFan()`/`skyPortEndFan()` (new, `#ifdef PORT`, `src/game/sky.c`) compute one shared `wScale` across every vertex in the whole fan (`sp274[]`/`sp94[]`, up to 5 verts), called once right after each fan's vertex array is populated and before its 1-3 `skyRenderTri`/`skyRenderFull` calls; `skyPortRenderPoly` now uses that shared value when set, falling back to its old per-call-local computation otherwise (defensive — no other caller exists today, checked: `grep` finds `skyRenderTri`/`skyRenderFull` used nowhere outside this file). **Verified:** same-frame before/after screenshots at `-level_22` frame 345 — `docs/img/bugs/d227-sky-seam-statue.png` (before, visible kink ~x=1000/1280) vs `docs/img/bugs/d227-sky-seam-statue-fixed.png` (after, same frame, continuous streaks, kink gone). Full 21-level `verify.sh sweep`: 21/21 PASS both before and after this change (no regressions). `bunker1`'s `worst_cell` framediff number is unaffected by this change — reproduced identically on the pre-fix build, it's the already-known stale-golden-baseline issue (see M-84/M-83 notes; owed a re-baseline, unrelated to sky.c). **Cradle checked too:** the "black rectangle" artifact visible there is confirmed pre-existing (identical on a pre-fix build capture) — that's the separate, already-documented FOV-coupled black-sky-past-frustum-edge symptom (D218/D222 family), not this defect; didn't chase it here. **Not fully closed:** did not re-verify the "moves at a different rate" half of the original report post-fix (the M-94 addendum's static-camera diff measurement wasn't repeated on the fix); the aspect-ratio-artifact alternate theory was never separately confirmed or ruled out, though the fix visibly closing the crease at a fixed resolution is itself decent evidence the crease specifically was a code-side seam, not a display-scaling artifact. Human eyeball still owed before merge, same as every other rendering fix landed without display access this session. **M-96: human eyeball done — seam/crack STILL PRESENT on Statue with the M-95 fix in.** The static-crease theory (verified by the frame-345 screenshot diff) is therefore not the whole story, or not the dominant contributor to what's actually visible in live play; the never-repeated "moves at a different rate" temporal theory from the original report is the next thing to check — a single-frame diff can't see it. **D227 NOT resolved; PR #43 stays in draft.** **Also M-96: user reports the N64 sky should be *almost static* and this build's scroll is *extremely fast* — stronger than M-93's "still reads too fast," bears on D176(a)'s fix magnitude itself, not just this seam; possibly the same wrong-magnitude tc-delta drives both symptoms, not yet investigated.** Full write-up: §H "D227 — M-96". **M-98: seam residual FIXED (same bug class as M-95, one field over) + scroll-rate quantitatively measured.** Re-derivation confirmed the tick-rate side is clean: `skyTick()` (unmodified N64 logic) adds `g_ClockTimer` (verified via `frametiming.c` to run ~1/tick under normal load, D193/D204's territory) to `g_SkyCloudOffset` once per logic tick — not a per-render-frame or double-counted path, ruling out a global-timing explanation for "extremely fast" (that would show up as everything sped up, not just the sky). The seam, though: M-95 shared `wScale` across a whole sky fan but **left `skyPortRenderPoly`'s S/T fold (`foldS`/`foldT`) computed per-call, from only that triangle's own 2-4 verts** — the exact same class of bug M-95 fixed for position, just one field over, and never touched. Two triangles in one fan can independently floor a shared vertex's S/T to a different multiple of 64 texels; nominally invisible (GL_REPEAT period 64) but each triangle bakes `(S - fold) * 32` into its own `s16` Vtx buffer, and two folds 64 texels apart produce tc values 2048 apart — large enough to crack at the shared edge. Fix: extended `skyPortBeginFan()`/`skyPortEndFan()` to also compute one shared fold across the whole fan (`s_skyFanFoldS/T`), threaded into `skyPortRenderPoly` the same way as `wScale`. Verified: `-level_22` frame 345 (same frame M-95's before/after used) now shows continuous streaks with no visible crease at the ~x=1000/1280 location, vs. the still-visible crease in `docs/img/bugs/d227-sky-seam-statue.png`; `verify.sh bunker1` PASS (worst_cell unchanged, the known stale-golden-baseline number, not a regression). **Scroll-rate data point (the M-96/M-97-requested measurement):** cross-correlating consecutive-frame captures (`GE_PCDUMP=345-355:1`) at a static camera gives a consistent **~7 px/tick horizontal shift at 640px capture width** — a full 640px screen-width sweep roughly every 90 ticks (~1.5s at 60Hz), which is hard quantitative confirmation of "extremely fast," not just a subjective read. **Root cause of that magnitude is NOT yet found** — `g_SkyCloudOffset`'s accumulation (1 texel/tick) and the vertex S/T geometry it feeds (`sub_GAME_7F097388`) are unmodified N64 logic, so if the rate is genuinely wrong relative to N64, the bug must be in how many on-screen pixels one texel-tick maps to (camera-to-sky-plane geometry, FOV, or a scale baked into the D176(a) Path B substitution) rather than in the accumulator itself — not investigated this pass. Human eyeball still owed on both the seam-close and the (unfixed) scroll-speed complaint. **M-99: human playtest — seam STILL PRESENT after M-98, AND confirmed view-angle-dependent (moves as the mouse/view moves); also reported still bad on Cradle and present on Surface.** Ruled out the cross-quad water/cloud scale-mismatch theory on the two `IsWater==0` levels tested (Statue, Cradle) — untested on any `IsWater==1` level. Headless camera-pan repro via `GE_INPUTSCRIPT` confirmed NOT to work (doesn't reach real mouselook) — this needs either a human playtest or a new debug hook to chase further. Full write-up + ranked candidate list for next session: §H "D227 — M-99". **M-100: ROOT CAUSE FOUND AND PROVEN — `s16` texture-coordinate overflow.** A user-supplied emulator-vs-ours screenshot pair on Surface (same framing) showed the real symptom is a *radial starburst*, not a crack — which redirected the investigation off the quantization-mismatch track M-94→M-98 had been on. New `GE_D227V` per-vertex probe on the Cradle frame-350 camera: the sky is one quad spanning **29,830 texels in S and 29,929 in T**, but `Vtx.tc` is S10.5 in an `s16` = **±1024 texels**, so **7 of its 8 texture coordinates overflow and wrap to arbitrary values**; the fold cannot help against a span 29x the representable range. The quad is split `gSP2Triangles(0,1,3, 0,3,2)` on the 0–3 diagonal and vertices 0 and 3 are exactly the two that keep one coordinate in range — hence "two halves with different patterns, split by a line", the original D227 report verbatim. All four w positive, so no projective pole. Apparent view-dependence needs no view-dependent mechanism: S/T depend on view, so the wrap point moves. **Confirmed by diagnostic build:** baking tc at 1-texel instead of 1/32-texel granularity (32x range, deliberately wrong scale) makes the starburst and the split *completely disappear* (`docs/img/bugs/d227-cradle-tcscale-diagnostic.png`) — no second defect hiding behind it. **D227 == D176(a) "Defect 2" == M-98's "Cradle tower starburst"; M-98 misfiled that capture as unrelated, which is what made D227 look headlessly-unreproducible — it reproduces statically.** M-95/M-98 stay (per-fan consistency is what makes subdivision seamless). **Fix not implemented:** subdivide until span < ~960 texels/primitive; subdivision math and cut placement are worked out (S is linear in w, so cut uniformly in w — uniform-in-screen is badly wrong), but the vertex budget is an open decision (unchecked 50 KB/frame pool; pure tessellation wants ~40% of it). See §H "D227 — M-100". **M-100b: FIXED — and the real cause is one step further back: a UNIT ERROR.** M-82 ("Defect 1") read `unk20`/`unk24` as texel counts and baked `tc` as `(S - fold) * 32` to convert to S10.5. They are not texels: `skyRender` sets them as `worldpos * 0.1f` and the N64 path hands them to the RDP coefficient block unscaled (`skyRenderTri`: `S * unk34 * sp368`), so they are **already in the RDP's native S10.5 1/32-texel units**. That stray `* 32` made every sky texcoord 32x too large and caused **three symptoms tracked as separate bugs**: (1) D227 (spans of ~30,000 *texels* vs an `s16` holding ±1024 → overflow → starburst); (2) over-tiling (~466 repeats of the 64-texel cloud per quad instead of ~15); and (3) **M-96's "the N64 sky is nearly static, ours races"**, measured at ~7 px/tick in M-98 — `g_SkyCloudOffset` advances 1 unit/tick, which is 1/32 texel, not 1. **The scroll complaint and D227 were the same bug**, which is why M-98's tick-path re-derivation kept coming back clean: the accumulator was never wrong, its unit was. **Fix:** `tc = (S - fold)` 1:1, fold rebased to a whole tile period (2048 units); the span then fits an `s16` unaided — no tessellation, no tile shift, which is also why the original N64 code never needed either. **Verified:** Cradle frame 350 (`docs/img/bugs/d227-cradle-fixed-m100.png`) soft cloud bands at correct scale, no starburst/split/moiré; `GE_D227V` reports `kS=kT=0` and max tc 31,513 of 32,767; Statue frame 345 clean; `verify.sh bunker1` PASS. M-95/M-98 kept (per-fan consistency); the tile-shift machinery kept as a graceful-degradation safety valve (only ~4% headroom left on the observed span). **Human play-test still owed** — both prior "fixes" passed static checks and failed live. See §H "D227 — M-100b". | -| D229 | **Water on `IsWater` levels renders green and pulses blue<->green on an interval (M-101, user playtest, Frigate `-level_26`; Surface 2 also an IsWater level).** Reported alongside green weapon textures on Frigate/Surface 2 — **that half was NOT a bug**: the branch under test was 2 commits behind main and those 2 commits were exactly the D217 fixes (#47 texpool alignment, #49 CI cache palette-content key); after merging main the user confirms the gun is good. | **FIXED (port-layer) — root cause: water image is ZLIB+CI8; pool holds raw 8-bit indices; N64's custom ucode expanded them to RGBA16 in TMEM at load, fast3d read index byte-pairs as 16-bit texels (g=2·idx mod 32 dominates → green). Fix: track `src_fmt` per TMEM load; RGBA/16b tile over a CI-sourced slot now imports via the CI8 palette path (`gfx_pc.cpp` import_texture). Frigate verified live (user: "looks better"); sweep + Surface 2 by-eye still owed.** Pre-existing (A/B proven), mechanism identified as above. Built plain `main` with none of the D227 work: `-level_26` frame 340 shows the **same green** (only the tiling density differs), so D229 is independent of D227. The quad is `sky.c`'s `IsWater` block1 (Frigate confirmed `IsWater=1` via `GE_D176` — which also settles M-99's ranked item 1: that path is textured and does go through `skyPortRenderPoly`). Draw state from `sub_GAME_7F09343C` (`unk_092E50.c:278`): tile 0 and tile 1 both RGBA/16b at **the same TMEM 0**, `masks=maskt=5`, tile 1 offset by `gDPSetTileSize(1, uls=90, ult=150, lrs=0, lrt=0)`, 2-cycle `LERP(TEXEL1, TEXEL0, PRIM_LOD_FRAC)` with cycle 2 `= COMBINED * SHADE` and the LOD fraction driven by **`sinf()`** — that sine IS the reported pulsing, so **one texunit resolves blue and the other green** and the sine fades between them. **Ruled out: the shade path** — `skyChooseWaterVtxColour` with measured `env RGB=16,48,96` / `WaterRGB=255,255,150` spans dark blue to pale yellow and can never be green; measured pixels ~`(5,70..175,20..37)` (R and B crushed) put the green on the texel side. **Not established:** why one texunit decodes green when both tiles share TMEM and format. One unproven oddity: `uls/lrs` are `uint16_t` and `width = ((lrs-uls)>>2)+1` gives tile 1 `-22` -> **65514**, though the matching negative `tex_width2` makes the sub-tile-window branch skip and fall through to the correct mask-based 32-texel wrap, so it may be harmless. **Next:** widen the `GE_D172` multitex probe (it filters on `tile1.tmem != tile0.tmem`, equal here, so it never fires) to dump both texunits' decoded state; capture a *sequence* across the sine period, since a single frame is useless (frame 340 reads green on all builds); and check `skywaterimages[2]`'s real format vs the RGBA/16b `sub_GAME_7F09343C` re-declares. **D227 is deliberately decoupled:** M-100b's safety valve takes `allowShift` and the water quad passes FALSE, leaving that path byte-identical to pre-D227 — shifting both tiles was observed live to flatten the cross-fade into constant green. Full write-up: §H "D229 — M-101". | -| D230 | **In-level music quality: a bass instrument sounds corrupted on PC, correct on N64 reference (M-105, user reports; repro refined M-106).** Filed to give the post-D77 residual its own label — D77 (in-level music *absence*) is RESOLVED (PR #42, missing `return` in `sub_GAME_7F0C0BF0` zeroed the seqp volume on the only in-level trigger path), so "music doesn't play" claims in tracked docs are stale; what actually remains is this quality gap. **M-106 repro, deterministic (not intermittent):** Control's elevator track and its regular in-level track both carry the bad instrument throughout; Cavern's elevator track has it too; Runway's track is otherwise fine but the same instrument enters ~5–7s after the track starts and sounds bad from then on. User confirmed against original N64 reference audio that a bass instrument belongs there on Runway — this is **not** a wrong-instrument/wrong-bank selection (rules out the D77 trigger-path family and the seqp-volume fix's neighborhood); the instrument choice is correct, only its *sound* is wrong on PC. Determinism (same track, same spot, every time) points at a static decode/synthesis bug for this instrument's wavetable/ADPCM data — most likely low-frequency-specific (pitch-shift/downsample artifacting, a wrap/loop-point error, or a clipping/gain issue that only bites bass-range samples) — rather than a live mixing/voice-stealing issue (D147/D152/D202 family), which would be intermittent. The mixer layer and the trigger layer are both proven working by every track that sounds right, so the suspect neighborhood is the seq/instrument-bank decode path (`csplayer.c`/`synthesizer.c`, bank loading), not `port/` audio plumbing. | **OPEN — static-analysis pass done (M-108), not runtime-confirmed.** Repro: Control (elevator + regular track, throughout), Cavern (elevator, throughout), Runway (~5–7s in). Traced the suspect neighborhood to the software ADPCM decoder in `port/src/mixer.c` — the PC replacement for the RSP's `aLoadADPCM`/`aADPCMdec` ucode ops (`csplayer.c`/`synthesizer.c` only emit ucode command lists; they don't decode samples themselves). Found two hardcoded assumptions that don't hold for the general ADPCM-book format: (1) `sAdpcmTable` (`mixer.c:174`) is declared `[8][2][8]`, hardcoding predictor `order=2`, but `order`/`npredictors` are per-instrument authored fields (`include/PR/libaudio.h` `ALADPCMBook.order`; `src/libultra/audio/load.c:428-429` computes `bookSize` from them) that the bank-relayout code (`port/src/romdata.c:718-736`) already handles generically — if this bass instrument's authored book uses `order != 2`, the 2-tap recursion at `mixer.c:223-240` would decode it wrong; (2) even at `order=2`, `aLoadADPCMImpl` (`mixer.c:177-192`) silently truncates any book over 256 bytes (`mixer.c:183`, `npredictors > 8`), while the decode loop's 4-bit predictor-select nibble (`mixer.c:219`) can legitimately address up to 16 rows — an instrument with `npredictors > 8` would read truncated/garbage rows for some frames. **Caveat weakening confidence:** N64 SDK ADPCM in practice is conventionally always `order=2` (the RSP ucode's own decode algorithm is essentially fixed to a 2-tap recursion industry-wide), so candidate (1) may not apply to a real N64 title's data; candidate (2) (`npredictors > 8`) is the more plausible of the two absent contrary evidence. Not confirmed against GE's actual ROM-authored book data (no live capture taken this pass). Next: extend the existing `GE_MIXERTRACE=1` trace's `[LOADADPCM]` line (`mixer.c:187`, already logs `count` — `count/16 = order*npredictors`) to flag any book where `count > 256` (proves truncation) during a Control run, and correlate the anomalous book to its channel/instrument via `seqplayer.c:1120`'s program-change. If no anomaly shows, this whole neighborhood is likely a dead end and the next suspect is the resample (`mixer.c:295-341`) or envelope/gain (`mixer.c:379+`) paths for bass-range-specific behavior. **M-120 (local-Qwen triage dispatch): a third hypothesis proposed and CHECKED, RULED OUT.** The dispatched read-only pass proposed that `afFixupBook`'s `port/src/romdata.c:733-737` conversion of the ADPCM book coefficients (BE ROM → LE host, via `afRd16`/`afWr16`) is backwards and should stay big-endian. Verified against the actual code and disproven: (1) that conversion is the identical BE→LE pattern used for every other field in the same function (`order`/`npredictors` two lines above) and in the sibling `afFixupAdpcmLoop`'s ADPCM state array a few lines down — not something special-cased for this one book; (2) `port/src/mixer.c`'s `aLoadADPCMImpl` does a raw `memcpy` of the already-converted book straight into a host-native `s16[8][2][8]` table with no further byte-swap, consistent with the coefficients being intentionally pre-converted to host order; (3) decisively, `afFixupBook` is one shared code path applied uniformly to every ADPCM book in the game — if this conversion were actually backwards, every ADPCM-encoded sound would decode wrong, not one bass instrument on three tracks, and the vast majority of the game's audio is confirmed correct. Do not re-propose this specific byte-order theory without new evidence; the standing M-108 leads above (predictor-count truncation / `order` mismatch) remain the live ones. **FIXED (M-121, v0.2.0 finalization) — root cause was a plain byte-order bug in a corner neither M-108 nor M-120 looked at: RAW16 wavetables.** Offline decode of the local NTSC ROM's instrument bank found exactly two `AL_RAW16_WAVE` (type 1) wavetables — instruments 2 and 51, both sharing base 0x2118 / len 790 in the `_instrumentstbl` segment — which decode as a clean ~110 Hz soft-attack bass synth sample when read as **big-endian** s16. That is the missing bass instrument on Control/Cavern/Runway. On N64 the CPU reads those bytes BE, so it plays fine there; on PC the mixer's resampler (`port/src/mixer.c` `alRaw16Pull` path) consumes host-native (little-endian) s16, so every sample arrives byte-swapped — a deterministic per-instrument corruption, exactly matching the M-106 repro (and explaining why every ADPCM-based instrument in the game sounds right: nibble data is byte-order agnostic). Both M-108 candidates are moot — every ADPCM book in both bank trees (scanned offline from the ROM) is `order=2, npredictors∈{1,4}`, so neither the `[8][2][8]` shape nor the 256-byte truncation can ever bite GE's data. **Fix (port-only, D55 in-place-fixup idiom):** `romdataFinishCartMap()` (`port/src/romdata.c`) now walks both bank trees (SFX + instruments; same ALBankFile layout as `romdataFixupAudioBank`) and bswap16s each RAW16 wavetable's `[tbl+base, +len)` range in place in the cart map — where the sample data lives for the mixer (`alBnkfNew()` points at the tbl segments directly; only the bank structs are re-laid out, D37). Shared ranges are deduped (swapping twice would undo the swap); every read is bounds-checked against the ROM size. Startup log: `romdataInit: D230 byte-swapped 1 RAW16 wavetable range(s) in place` (one range: the two instruments share the sample data). Byte-level verification done (BE decode of the ROM range = clean tone; post-swap LE decode identical by construction); **owes a by-ear pass** on Control (elevator + level track), Cavern elevator, and Runway ~5–7 s in. | -| D233 | **All levels (intermittent): indoor level geometry invisible near doors — you can see through walls/floors into rooms you can't see into, while world objects (terminals, furniture) in that space still draw (M-106, user QA report; screenshots `docs/img/bugs/20260912-cullingbug-bugged.png` vs `-notbugged.png`).** Root-caused M-107 (session-016TaKy6, port/fast3d only): **fast3d's CPU-side "trivial reject" AND-test in `gfx_sp_tri1` (`port/fast3d/gfx_pc.cpp:1455-1460`) has a latent w-sign bug independent of D222/D106.** The per-vertex outcode bits computed in `gfx_sp_vertex` (`x<-w`/`x>w`/`y<-w`/`y>w`/`z>w`, `gfx_pc.cpp:1372-1386`) are only valid half-space tests when `w>0`; for a vertex that has crossed behind the camera plane (`w<0` — common when the camera is close to large room-structure polygons, e.g. walls/ceiling trusses near a doorway) the comparison sense is flipped, so its outcode can come out wrong. If that spurious bit happens to match the other two (genuinely correct) vertices' bits, `v1->clip_rej & v2->clip_rej & v3->clip_rej` fires and the whole triangle is dropped before it ever reaches OpenGL — even though GL's own homogeneous clipper (which *does* handle `w<0` correctly) would have rendered the visible part of it. Confirmed against the two screenshots: same room/camera/ammo-HUD, one frame is missing the room's ceiling trusses/walls (replaced by flat sky) while the console/terminal props in the same room still draw fully — exactly the "big background polys vanish, small prop models don't" split you'd expect, since large near-camera polygons are far more likely to have a vertex cross behind the eye than small self-contained prop meshes. The backface-cull code 6 lines below (`gfx_pc.cpp:1462-1495`) already special-cases this exact `w<0` hazard for its own cross-product sign (`(v1->w<0)^(v2->w<0)^(v3->w<0)`) — the trivial-reject block above it never got the same treatment. **Independent of D222** (D222 is a game-logic frustum-cull bug in `src/game/fr.c`/`bondview2.c` that only manifests at non-default `Video.FovScale`; this is a GPU-pipeline clip-rejection bug in `port/fast3d/` that fires at any FovScale, including the default 100, whenever the camera gets close to a large polygon — matching the report's "all levels, near doors" framing with no FovScale mentioned). Also independent of D106 (D106 fixed the *game-side* portal-visibility bbox computation for a different z==0 edge case in `bg.c`; this is the *renderer-side* per-triangle clip decision, a different stage of the pipeline entirely) — same neighbourhood/symptom vocabulary ("things vanish near a portal-adjacent boundary"), different bug. | **FIXED (port/fast3d/gfx_pc.cpp, `gfx_sp_tri1`) — high confidence on mechanism, UNVERIFIED visually.** Fix: skip the trivial-reject AND-test entirely whenever any of the triangle's 3 vertices has `w<0`, deferring to GL's clipper instead (mirrors the cull code's existing w-sign handling one block below). Change only ever *adds* triangles that were previously dropped — cannot make anything newly invisible, so it's a safe, narrowly-targeted fix with no game-logic touch (fast3d is PC-only code, no N64 build parity to preserve, no `#ifdef PORT` needed). **Build verified green** (`./build-pc.sh` equivalent — MSYS2 mingw64 cmake+ninja, full `ge007.x86_64.exe` link succeeds, only one pre-existing unrelated `-Wformat` warning in the same file). **VISUALLY VERIFIED (M-108):** user played `-level_26` (Frigate — corrected level id, the old `-level_02` note above predates the `bondconstants.h` numbering check) and confirmed the doorway/ship-corridor geometry no longer flickers or vanishes near room boundaries.

Could equally be a per-instance object/prop transform or cull-volume bug in `src/game/propobj.c`/`chrprop.c` (out of this task's `port/fast3d/` scope, and out of the `src/game/*` model/anim exclusion in the brief regardless). **No fix attempted — do not have enough evidence to touch code.** | **VISUALLY VERIFIED FIXED (M-108) — mechanism still unexplained.** User confirmed on a live Dam playthrough (post-D233 fix, correct `-level_26`/Frigate session's build) that all guard towers along the dam now render, not just the first. No code change was made specifically for D234, and the M-107 investigation's own reasoning argued D233's mechanism doesn't fit this symptom (towers viewed from a distance, not a close-camera w<0 case) — so either that reasoning was wrong, D233's fix had a broader effect than analyzed, or the original symptom was intermittent/state-dependent rather than deterministic.

The M-87 matrix described these as distinct from the start ("AK47 viewmodel has white (missing-texture) patches on the magazine + barrel" vs. the green/blue colour corruption) — this playtest confirms they have distinct root causes, since fixing one left the other untouched. | **FIXED (`port/fast3d/gfx_pc.cpp`, `palette_to_rgba32`) — a real byte-order bug, not a texpool/decode-never-ran issue as originally guessed.** `GE_TEXDUMP` on Facility (`-level_34`) found ~14% of LOD-textured uploads (fmt=CI, `palette_fmt=G_TT_IA16`) rendering solid near-white; a `GE_D228` correlation probe ruled out the texpool/RC2-clip hypothesis (the decoded size exactly matched the tile's base image every time — the data reaches `import_texture` fine, sized correctly). The actual bug: `palette_to_rgba32`'s `G_TT_IA16` branch read `intensity = palentry & 0xff` (low byte) and `alpha = palentry >> 8` (high byte) — backwards relative to the already-correct direct-IA16 decode two functions above it in the same file (`import_texture_ia16`: `intensity = addr[2*i]` (first/high byte after `gfx_dp_load_tlut`'s `PD_BE16` swap), `alpha = addr[2*i+1]`). A dim, fully-opaque palette entry (e.g. intensity=0x58, alpha=0xff) decoded backwards as bright and mostly-transparent (intensity=0xff, alpha=0x58) — exactly the white-patch symptom, on any CI-format material whose TLUT happens to be IA16 rather than RGBA16 (weapon metal/grip materials commonly are, since IA is a natural fit for grayscale metal with a separate opacity channel).

The earlier "262 enum vs 261 bank ⇒ needs a -1" arithmetic was right about the *symptom*; the *mechanism* is the alias, and `BIG_CLANK_SFX`=261 → slot 260 is in-bounds (never an OOB). Upstream `n64decomp/007` `snd.c` byte-matches with no `-1` and no `NON_MATCHING` guard — correct, because the N64 struct offset supplies the -1. **NOT D205 (2)** explosion→scream (169-183 → slots 168-182, all still explosions) — stays with D205. | **FIXED (M-76, `src/snd.c:1001`, `#ifdef PORT` → `soundArray[soundIndex - 1]`, N64 line verbatim under `#else`).** ABI/layout-only, D3x class (pointer-width struct-layout reconciliation); no game-logic change. Build clean; BUNKER1 60s crash-free; `-level_09` golden framediff 3/3. **User by-ear A/B vs N64 = PASS (M-77c)** — armour / melee / silenced PP7 all correct now → D202 closed, D205 down to symptom (2). Committed `378386d1`. Scratchpad `rom_sfx_decode.py` / `exact_match.py` / `diff_bank.py` still walk slots 0-based — correct for "what is at bank slot i", but a check against a `SFX_ID` must compare to slot `id-1`. | -| D207 | **Alarm klaxon starves combat SFX and (per user) doesn't recover after it stops — surfaced by D206 (M-77, ROOT-CAUSED, fix designed not applied).** Before D206, `ALARM3_SFX` (id 163) resolved to the wrong bank slot 163 — a **one-shot** sample: played once, freed its voice. After D206 it correctly resolves to slot 162 = the **real infinite-loop klaxon** (`decayTime=-1` -> `SOUND_FLAG_LOOPED`; ADPCM `loop.count=-1`). Played by `handle_alarm_gas_timer_calldamage()` (`src/game/propobj.c:14457`) with owner `&ptr_alarm_sfx` while `alarmIsActive()`. It now **permanently holds 1 of only 8 SFX voices** (`MUSIC_SFX_SEQ_MAYBE_MAX_SOUNDS=8`, `src/music.c`), at priority `0x41` (looped sounds get `decayTimeFlag + 0x40`, `sndSetupSound` `snd.c:820`) — and is **exempt from the port's preemption scan** (`snd.c` ~369: `!(unk3e & 0x12)` refuses to steal any LOOPED/RETRIGGER voice; the M-65 carve-out only covers *ownerless* loops, and the alarm is owned). **M-77b:** the voice-starvation hypothesis did NOT hold up — a BUNKER1 `GE_FORCEALARM` + scripted-fire soak showed **0 true drops** (`sndDisposeSound` no-voice sites instrumented), the designed last-resort preemption pass **never fired**, and `g_sndAllocatedVoicesCount` recovered to 0 after every alarm-off (no leak). The earlier "~20% drop" was a log-latency artifact. The alarm klaxon (`ALARM3` slot 162) is a *continuous, gapless* infinite loop — a real GE alarm pulses — so the leading remaining explanation is **perceptual** (the drone masking gunfire, and/or slot-162 mixed too loud vs N64), or genuine 8/8 starvation only on a heavy level not yet tested. Needs a user repro. | MONITORING (M-77c: user reports the alarm is acceptable in play after D206; no fix shipped) — **the voice-starvation hypothesis did NOT hold up (M-77b).** The designed last-resort LOOPED-preemption pass was built, and instrumented drop counters (`[D207-DROP]` at both `sndDisposeSound` no-voice sites) + a `[D207-YIELD]` trace were added. Result on BUNKER1 (`GE_FORCEALARM` + scripted sustained fire, ~85 s): **zero true drops**, the last-resort pass **never fired** (pass-1 always found a non-looped victim), and `g_sndAllocatedVoicesCount` sat at 1 during quiet alarm and recovered to **0** after every alarm-off — no leak, no permanent starvation. The earlier "~20% dropped" figure was a measurement artifact (log-line latency, not real drops; every requested sound eventually got a voice via the `unk38` retries). So the fix was **reverted** (kept: nothing in `snd.c`; D206 `-1` only). BUNKER1 combat is too light to peg the 8-voice pool. **Next session needs a real repro from the user:** which level + weapon, and a `GE_AUDIOTRACE=1` capture at the failing alarm — is it (a) genuine 8/8 starvation on a heavy level (Facility/Silo/Statue firefight), (b) a leak that only triggers on a specific alarm-stop path, or (c) perceptual — the continuous klaxon drone masking gunfire / the alarm mixed too loud (check `ALARM3` slot 162 volume vs N64). Temp `GE_FORCEALARM` probe kept in `src/game/propobj.c` for that work. **M-78: re-added just the `[D207-DROP]` counter (NOT the reverted last-resort pass) at both `sndDisposeSound` no-voice sites in `snd.c` (gated on `GE_AUDIOTRACE`), logging `state`/`prio`/`flags`/`count=N/max`, so the user's real-level capture is decisive between (a)/(b)/(c). Static re-check of `ALARM3` slot 162 this session: `sampleVolume=80` (vs gunfire 90-110, punches 100-110 — the klaxon is quieter per-sample, not louder, weakening the "mixed too loud" half of (c)); `decayTime=-1` + `keyMax=8` (`&0xf0=0` → NOT `SOUND_FLAG_RETRIGGER`) → it is a continuous looped sound by design on N64 too, the pulse is baked into the 225→7512-sample ADPCM loop body. So (c) narrows to "the continuous drone masks gunfire" or a loop-point playback defect; (a)/(b) still need the heavy-level capture. Launcher `build-pc/d207_run.ps1` added (forced-alarm auto-repro on level_09).** | -| D208 | **Player weapon-fire sound goes permanently silent mid-firefight (all other SFX unaffected) — `struct` field `bondview.h:200 s32 field_A48` is used as a second `ALSoundState *` sound-handle slot, but is only 32 bits wide on PC (M-78c, ROOT CAUSE FOUND, D3x pointer-width class).** This is the "doesn't recover after the alarm stops" half of the user's D207 report — a distinct bug from D207's voice-pool question. The player's per-hand fire sound is double-buffered across two handle slots: `hands[h].audioHandle` (`ALSoundState *`, correctly pointer-width) and `hands[h].field_A48` (`s32`). `gunfire.c:3186-3200` (`bondfirefunc`) each trigger interval calls `sndPlaySfx(bank, idx, (ALSoundState *)&handptr->field_A48)`, and `sndPlaySfx` writes the new state through it as `pendingState->link.next = nextState` — an **8-byte pointer store** into a 4-byte field, overrunning into the adjacent `field_A4C` (which is the auto-fire sound-cadence timer, written back every frame at `gunfire.c:3168`). `sndUnlinkClearSound` likewise does an 8-byte `state->state->link.next = NULL` there. The two writers stomp each other; after enough double-buffered fire cycles `field_A48` holds a value that is neither `0` nor a valid pointer, so the `else if ((ALSoundState *)handptr->field_A48 == 0)` re-arm gate in the double buffer is **never true again → no further player gunshot is ever issued.** `audioHandle` alone can't cover because the code only replays into it `if (audioHandle == NULL)` and the async `sndDeactivate(audioHandle)` leaves it briefly non-NULL, deferring to the jammed `field_A48` branch. **Evidence (user Bunker capture, `audiotrace.log`, silenced PP7 = idx 46):** idx-46 `sndPlaySfx` requests stop dead at t=776609203515 (log line 18930 of 25086) while guard fire (109), pickups (232), impacts, doors all continue to the end; at line 19159 the player-gun slot `0x70076630` is caught holding `was 0x000001db00000000` — a torn 64-bit value = `field_A48=0x00000000` + `field_A4C=0x1db` (475, a `g_GlobalTimer`-relative cadence stamp) read as one word. The alarm is not required — it just raises `sndPlaySfx` churn so the tear is hit sooner. On N64 both fields are 4 bytes, `audioHandle` is a 4-byte pointer, and `&field_A48` punned as `ALLink*` is a 4-byte `link.next` write — all consistent, no overrun. **`bondview` / `hands[]` is runtime-only state (`g_CurrentPlayer`), never ROM-serialized**, so widening `field_A48` to pointer width is layout-safe (no by-offset or ROM-cast access — grep-verified; only `field_A50`/`field_A4C` sit after it and are plain `s32` timers). | FIXED + user playtest-verified (M-78d) — Bunker firefight: player gunshots persist through the whole engagement and survive the klaxon stopping. Committed 7601b9db (PR #29, merged). | -| D209 | **Every AI character in the game is locked to a *walk* animation regardless of the speed the ailist commands — `act_ubytes.padding[45]`, a raw-byte alias into the action union for `act_gopos.unk59` (the SPEED tier), shifts from offset 45 to 81 at 64-bit (M-81, ROOT CAUSE of D193, D3x pointer-width class).** GE character *travel* is animation-root-motion driven, so the bound locomotion animation sets the speed. `get_sound_at_range()` (`chraction.c:3573`, the locomotion-anim selector — misleading name) picks `ANIM_DATA_sprinting`/`running`/`walking` (and the one-handed/female variants) from its `arg1` tier. Its **only** caller, `play_hit_soundeffect_and_proper_volume()` (`chraction.c:3665`), passes the tier as `self->act_ubytes.padding[45]` — a raw byte read out of the `ChrRecord` action union rather than the named field. On N64 that alias is exact: `struct act_gopos` = `{coord3d targetpos@0, StandTile *target@12, waypoint *target_path@16, waypoint *waypoints[6]@20, u8 curindex@44, u8 unk59@45}`, so `padding[45]` **is** `unk59`. On x86-64 the three pointer members widen 4→8 B (`target@16, target_path@24, waypoints@32`), pushing `curindex`→80 and `unk59`→**81**, while the literal `45` now lands inside `waypoints[1]` (spanning 40..47) — specifically **byte 5 of a heap pointer**. The port's arena is low-4GB (`0x00000000_70xxxxxx`), so byte 5 is **always `0x00`** → `arg1 = 0` → `ANIM_DATA_walking` / `ANIM_DATA_walking_unarmed`, unconditionally, for every AI chr on every level since the 64-bit transition. The named-field reads (`chrlvApplySpeed(self, ..., (s32) self->act_gopos.unk59, ...)` at `:9104`, and the `unk59 == 2` / `== 1` `modelSetAnimSpeed` tiers at `:9106-9130`) resolve correctly, which is why the tier *looked* right everywhere it was inspected — only the alias was broken. **Runtime evidence (Cradle `-level_41`, `GE_D193A` extended with `tier`/`aidx`):** all six chrs report `act=15 ACT_GOPOS tier=1 SPEED_RUN` on 420/440 samples, yet `aidx` (live `model->anim` reverse-resolved against `animation_table_ptrs1`) is **40 = `PTR_ANIM_walking`** for Trevelyan (chr 0) and **107 = `PTR_ANIM_walking_unarmed`** for the guards on every single sample — `aidx 42 (running)` / `41 (sprinting)` never appear. Travel speed sat in a flat 140–155 u/s band for all of them, independent of animation, which is the walk-cycle stride. `act_ubytes` has exactly one use in the whole tree, so this is a single site. Both callers of `play_hit_soundeffect_and_proper_volume` reach it with `actiontype == ACT_GOPOS` (`:3723`, immediately after `actiontype = ACT_GOPOS; act_gopos.unk59 = speed;`; and `:9087`, inside the explicit `else` of `actiontype == ACT_PATROL`, mirroring the `chrlvApplySpeed` split directly below it), so reading the named field is exactly the byte N64 reads — no behavioural change. | **FIXED + user-playtest-verified (M-81).** `chraction.c:3665`, `#ifdef PORT` → `get_sound_at_range(self, self->act_gopos.unk59, ...)`; the N64 line kept verbatim under `#else`. ABI/pointer-width only, no game-logic change (rule-2 narrow exception, D3x class). User ran Cradle on the fix build: **Trevelyan and the guards run.** Also corrected the `// guess: room` comment on `unk59` (`src/bondtypes.h:2191`) — it is the SPEED tier. | -| D210 | **`chrToPatrol()` leaves `act_patrol.lastvisible60` uninitialised on PC — a raw-byte union alias (`act_init.padding[0x13]`) that shifts when `act_patrol` widens (M-82, A1 class, sibling of D209).** `chrToPatrol` (`chraction.c:3872`, sets `ACT_PATROL`) does `self->act_init.padding[0x13] = -1;` — union-relative byte `0x4c`. On N64 `struct act_patrol` = `{patrol_path *path@0, s32 nextstep@4, bool forward@8, waydata@0xc (0x40 B), s32 lastvisible60@0x4c, f32 speed@0x50}`, so byte `0x4c` **is** `lastvisible60`, initialised to `-1`. On x86-64 the leading `path` pointer widens 4→8 B, so everything after shifts +4: `lastvisible60` is now at `0x50`, and the literal `0x13`/byte-`0x4c` write lands in the last 4 bytes of `waydata` (`segdisttotal`). Net PC effect: `lastvisible60` keeps whatever garbage the previous union arm left, and the "chr hasn't seen the player recently → break off / resume patrol" gate at `chraction.c:~9347` (`(act_patrol.lastvisible60 + CHRLV_DEFAULT_TIMER) < g_GlobalTimer`) reads that garbage on the first tick(s) after entering PATROL — until `chr.c:2569` / `chraction.c:3482` / `:9359` overwrite it (only when the chr actually sees the player). Same root class as D209 (raw index into a union arm whose pointer members widened); found by the post-D209 A1 sweep. Only new instance in the sweep — `act_init.padding[0..3]` in `chrlvTickAnim`/`chrlvTickDead` alias `act_anim`/`act_dead`, both pointer-free, so those are layout-stable. | **FIXED (`chraction.c:3872`, `#ifdef PORT` → `self->act_patrol.lastvisible60 = -1;`, N64 line under `#else`).

Re-counting the same file: idx 109 is requested **128x** not 256x (the double-log artifact D204 already corrected for M-63 on this very index), = 4.31/s across ~11 guards = ~0.4/s each, **~6x UNDER** the AK47's own `SoundTriggerRate` (`RATE_AK47`=4 ticks => 15/s ceiling) — so the `field_178` gate never binds; and impacts are plentiful in the same window (~30 ricochet/wall-hit 19-41, 69 x2 flesh, 12 body-falls 123-132, 14 yelps 134-147). The eye-catching monotone sweeps 134->147 / 123->132 are the ground-truth round-robin `male_guard_yelp_counter` (`chraction.c:2454-2470`), faithful, not a broken selector. **The 109 traffic is normal in-spec guard combat**; do NOT open the pccg-stan/LOS geometry investigation on this evidence.

Looking nearly straight up the tower is exactly the camera angle that produces one sky triangle spanning from near-camera to horizon-grazing texel coordinates, i.e. the >1000-texel-span case the fold logic already flags as unhandled.

Compounded by `curLocus` being declared as the 8-byte placeholder `move_bond_temp_struct` (too small for the widened record) and a `(s32)coords` pointer-truncation AV waiting in `stanGetMoveBondCollisionTiles`. **Fix:** `#ifdef PORT` — write record fields by name, declare `curLocus` as the real struct, `PORT_PTRADD` for the truncating cast (`src/game/stan.c`, `src/game/bondview2.c`; no game logic).

The dominant record sets `gsDPSetCycleType(G_CYC_2CYCLE)` + `gsDPSetTextureLOD(G_TL_TILE)` + `gsDPSetCombineMode(G_CC_INTERFERENCE, G_CC_MODULATEIA2)` and binds **two** tiles: tile 0 = IA8 "smoke" @ TMEM 0, tile 1 = RGBA16 "fire" @ TMEM 0x188. `G_CC_INTERFERENCE` cycle-0 = `TEXEL0 * TEXEL1`. **fast3d's `gfx_lod_tile_offset()` returns `0` unconditionally** on the `!gfx_detail_textures_enabled` branch — a D107 fix for GE's mip textures (whole chain loaded in one LOADBLOCK at TMEM 0; `port/src/video.c:225` sets the flag `false`).

D75 animated-model family but a *position* defect, not absence (M-33: gun-barrel Bond renders fine).

"Player spawning OK" localises it to the render-side model, not `g_CurrentPlayer`. See `GRAPHICS-BACKLOG.md` D173. | OPEN — observed, not investigated. **M-87 user playtest: still present** — "Bond floating in the sky / cutscene glitch thing still exists." Related, newly reported: **in some cutscenes Bond spins in circles** (named instance: end of Cradle, when Trevelyan falls) — likely the same actor-position/anim-root class rather than a new bug; logged under D148/D160 (`GRAPHICS-BACKLOG.md`) since it's cutscene-triggered. **M-106 investigation (static only — no build/runtime access in this worktree, see note below):** checked the two most D209-shaped candidates for a puppet Y-position aliasing bug and RULED OUT both. (1) `chrSpawnAtPad`/`chrSpawnAtCoord`/`chrAdjustPosForSpawn` (`src/game/chraction.c:10653-10794`) — the puppet-spawn path a cutscene `guard_play_animation`-style AI cmd would use. `PadRecord.stan` (`src/bondtypes.h:1744-1751`) is a ROM-serialized *pointer* field (`StandTile *stan` at offset 0x28) — exactly the tail-pointer shape D122/D126/D132 warn about — and `tools_pc/d88_emit.py`'s `emit_pad()` zeroes it on conversion with a comment claiming it's "dead-on-load, always set before use." **Verified this claim is TRUE, not a converter bug**: every `PadRecord` literal in the N64 source asset tables (checked `assets/obseg/setup/UsetupdamZ.c:37-51`) initialises `stan` to the literal `0` — the ROM binary never carries a live pointer there on N64 either, so zeroing it on PC is byte-identical behaviour, not a regression. `chrAdjustPosForSpawn` receiving a NULL seed `StandTile*` is therefore the original game's normal case, not a port defect. (2) The anim-root-motion Y-accumulation chain (`modelTickAnim`→`modelSetAnimFrame2WithChrStuff`, `model.c:3060+`, `pos24 = pos34 + rotate(pos)` at `model.c:3322`) was already exhaustively audited for exactly this class of bug during D193/D209 (M-80/M-81) and found self-consistent, with the `padding[]`-union sweep that found D209/D210 explicitly noting `act_anim`/`act_dead` (the union arms active during a played-animation/dead puppet) are "layout-stable" (`porting-notes.md` §A, D210 entry) — i.e. that sweep already covers the cutscene-puppet actiontype, and it came back clean. So the two most probable D209-style aliasing sites for this specific symptom are both cold. **Did not find the actual root cause.** Did not get to: the *separate* Cuba end-credits case (`front.c` `init_menu18_displaycast`/`constructor_menu18_displaycast`, `front.c:7821-8320`+ — a **different**, single-actor "cast roster" display model shared by the intro roster and the credits roster, using `getsuboffset`/`subcalcpos`/`cast_rootpos_smoothed` root-motion smoothing, not the in-level chr path at all) — spot-checked `getsuboffset` (`model.c:684-700`) and it is `#MATCH`-verified clean, but did not trace the smoothing math or confirm this is even the code path the "JB above Natalya" report hits (that report implies two actors on screen at once, which this single-`cast_model` code doesn't obviously support — may be a distinct, not-yet-located two-actor cutscene-puppet path). **Confidence: LOW-MEDIUM that this is the D209-style struct-aliasing family at all** — the two most likely aliasing sites check out clean, which argues *against* the shared-root-cause theory for D173 specifically (unlike D160, where the analogous check also came back clean but for a different reason — no pointer fields to alias in the first place). Next investigator: get a live Cradle (`-level_41`) capture of Trevelyan's chr during the death sequence with a position-logging probe (none shipped yet — would need a new `#ifdef PORT` env-gated trace, not added this session per the no-build-verification constraint), and separately locate the actual two-actor Cuba credits code path (grep for wherever `intro_char_table`/cast display is invoked with two simultaneous models, if it exists — not found this session). **M-141: no new lead this session** (see D243's M-141 entry) — checked whether D243's stale-memory front-end/menu bug could share a mechanism with this puppet-position bug; no code-level link found, kept as an unconfirmed hypothesis to watch for during the next live cutscene capture, not a new suspect to chase on its own. **M-141: Steam Deck playtest confirmation** — user reports Bond floating at level start on both Dam and Facility ("chemical plant"), "but fine when it moves to first person" (matches this row's own framing exactly: player spawn/first-person is correct, only the third-person render-side puppet floats). No new mechanism; corroborates the bug is general across levels, not Dam-specific. **User confirms D292** (Bond sunk into the floor on death) **is the same underlying bug**, a third instance alongside level-start floating and the Cradle cutscene spin — see D292 for the consolidated cross-reference. | -| D179 | **Packaged build crashes after the logos — the D43/D69 model + bg sidecars are ROM-derived and absent from any build that has no ROM (M-34, alpha-release QA).** The first `goldeneye-pc-port-*-win64.zip` from CI (bundle-win.sh) shows the Rare/Nintendo logos (compiled-in `assets/rarewarelogo.c`) then AVs at `0x6b157a88`/`0x70157a88` — symbolised: `modelPromoteNodeOffsetsToPointers` (`model.c`) ← `load_object_fill_header` (`objecthandler_2.c`) ← first prop/item model load. Root cause is **not** a code regression: the port loads PC-layout model geometry from `data/pcmodels-/{pcmodels.bin,manifest.csv}` and stage bg/stan from `data/pccg-/{pccg.bin,manifest.csv}`, both produced offline by `tools_pc/d43_emit.py` / `d69_emit.py` from the ROM (see `port/src/pcmodels.c` / `pccg.c`; `pcmodelsReserveSize` logs *"pcmodels.bin not found — model loads will fail"* and returns 0). CI has no ROM so it never runs the emit scripts, and the two `data/` dirs are (correctly) gitignored ROM-derived game data — **cannot be committed or shipped** (converted Nintendo/Rare geometry, DLs, collision, stan nav; = distributing assets). A local build with those dirs present runs clean (verified M-34: 1741 frames, `romdataInit ... mapped at 0x10000000`, `pcmodels: 512 sidecars`, `pccg: 73 sidecars`, no crash — so `0x10000000` is *not* the problem here). The `docs/building.md` sidecar-gen step was also missing entirely. **Fix = release-side, backlogged** (`docs/BACKLOG.md` → "Alpha release"): bundle the emit scripts + their committed inputs as a pure-stdlib-Python asset-prep tool the user runs once against their own ROM (~5 MB output, no MIPS toolchain). Secondary/latent: the fixed-address `VirtualAlloc((LPVOID)0x10000000)` in `romdata.c` has no working fallback (`"using heap copy — direct ROM reads will fail"` then limps into the same crash) — didn't bite M-34 but will on a machine where something occupies `0x10000000`; harden separately (reserve earliest in `main`, or retry low bases and derive all segment math from the base obtained). | Diagnosed, not fixed — release packaging gap + latent `romdata.c` fallback | -| D180 | **Native-PC input pass (M-XX QoL run, `qol/native-pc-input-menu`, port-only).** Three parts, all config-gated with default = prior behaviour: **(WI-1) `Input.MouseCaptureMode`** (0 = legacy always-grab; 1 = Quake-style click-to-lock) in `port/src/input.c` + `port/src/video.c` — in mode 1 the OS cursor is free until a click lands in the game window (`SDL_MOUSEBUTTONDOWN` → `inputNotifyClick`), and ESC / focus-loss / entering any front-end menu (`current_menu != MENU_RUN_STAGE`) frees it again; re-entering a stage while still "armed" re-locks so unpausing needs no click. `reconcileGrab()` runs once per controller-0 poll. Mouse buttons are suppressed from the game while the cursor is free in-stage (no phantom fire). Controller paths untouched. **(WI-2) absolute-cursor menu tracking** — when capture mode is on and the cursor is free in a menu, the D165/D169 pointer P-controller takes its target from the real cursor's absolute window position mapped onto the live virtual front-end rect (`getPlayer_c_screen*`), giving true 1:1 tracking instead of the relative-delta estimator.

Default `1.0f` ⇒ exact no-op, every headless golden dump byte-unaffected; `0.0` disables explosion/effect screen shake, up to `10.0` exaggerates it.

Same policy class as a future FOV hook. | **Menu row pulled (v0.2.1, user testing).** The hook is correct on its own narrow terms — `viShake()` is called only from `explosion.c`, so the slider does exactly what it says (scales explosion/effect shake) — but that's a much narrower scope than the "Screen shake" label implies to a player: it does not touch the always-on walking head-bob or any getting-shot reaction, so a user swinging it from 0 to max during ordinary play sees nothing and reasonably calls it broken.

Columns 0 and 1 are scaled by the same factor `tan(half_orig)/tan(half_adj)` → H and V FOV widen uniformly, aspect ratio exactly preserved (no stretch), and because the game rewrites fovy every frame for aim-zoom the scale composes with zoom for free. Ortho matrices (`P[3][3]==1`) are left untouched so HUD/menu 2D is unaffected. `Video.FovScale` = percent of the original vertical FOV, 50–150, **default 100 ⇒ `g_fov_scale == 1.0f` ⇒ guarded early-return, zero FP ops on the matrix ⇒ golden dumps byte-identical**. F10 overlay row "FOV scale %". Math checked offline (`s=1.25 → fovy 60°→75°`, aspect held at 1.3333). | **PARTIAL — M-84 refix: game-side FOV scale (`src/fr.c`, `#ifdef PORT`), front-end gated, user-verified.** Original M-83 note follows. LANDED, port-only; build clean; `bunker1` framediff worst_cell 12.219 vs 12.221 baseline (= render noise, no-op confirmed). **M-84 refix — the fast3d hook only scaled *pure* perspective loads; GE draws the world through `g_CurrentPlayer->field_10E0`, a projection × view matrix pre-combined on the CPU (`bondview2.c:8224`) that failed the `gfx_apply_fov_scale` guard, so only the pause/watch model + sky FOV changed (user report).** Moved the scale game-side to the `guPerspectiveF` chokepoint (`fr.c:718`, `#ifdef PORT`, `frFovY *= portFovScale`, clamp 160°), which lands *before* the CPU combine; fast3d `gfx_apply_fov_scale`/`gfx_set_fov_scale` removed; `port/src/video.c` sets `f32 portFovScale`. Also gated to `lvlGetCurrentStageToLoad() != LEVELID_TITLE` — the front end (main menu / file+mission select / briefing) renders through the same path (`lv.c lvlRender`) and its 3D is authored at a fixed FOV. **User-verified: front end unaffected + in-level view widens (Dam tunnel at high FovScale).** M-85 headless nit check (`-level_09`, FovScale 100 vs 120): **HUD-static confirmed** — the ammo counter ("7 | 93") sits at the identical bottom-right screen position in both, and the door-arrow stays square (no 4:3 stretch); viewmodel scales down + stays bottom-right anchored. **aim-zoom-compose — M-86 static analysis: correct by construction.** `bondview2.c:3123` lerps `zoominfovy` then `viSetFovY()` stores it in `g_ViBackData->fovy`; `fr.c:737` applies `frFovY = fovy * portFovScale` **once**, at the per-frame chokepoint, *after* the zoom lerp. Hipfire and zoomed states scale by the same factor so the zoom magnification ratio is preserved exactly; no double-application; the smooth zoom interpolation is unaffected (scale is post-lerp). Residual human eyeball (low risk, cosmetic) at FovScale ~120–150 + full aim-zoom: the viewmodel (`c_perspfovy`, `bondview.c:644`) and frustum-cull (`currentPlayerSetCameraScale`) use the *unscaled* fovy, so a subtle viewmodel-scale or edge-cull-early mismatch is possible; the scope reticle is 2D screen-space, unaffected. Caveat (same root): edge geometry culls a hair early at large scale (cosmetic). **User-verified good at big FovScale.** New adjacent report → **D220**: 1P muzzle flash position shifts upward at higher FovScale (Jungle, M16) — likely the same unscaled-viewmodel-fovy root as the caveat above. Wide FOV also exposes the per-level draw-distance boundary → **D218** (logged, parked). **M-87: the frustum-cull residual is a real bug, not cosmetic** → split to **D222**. | -| D212 | **Anisotropic-filtering config wiring — `Video.Anisotropy` (M-83 QoL wave, port-only).** The fast3d GL backend already implemented `set_anisotropy_level` / `get_max_anisotropy_level` and applied `GL_TEXTURE_MAX_ANISOTROPY` on mipmapped tiles with a hardcoded `current_anisotropy_level = 4`; there was no way to configure it. Added the `gfx_set_anisotropy_level()` extern-C wrapper in `gfx_pc.cpp` (clamps to `[1, GL max]`, `reset_texture_state()` so live changes take), declared in `gfx_api.h`, and `Video.Anisotropy` (1–16) in `port/src/video.c` wired through `videoApplyImageOptions()` on init + live-config. **Default 4 = the value fast3d already applied ⇒ no visual delta at defaults.** F10 overlay row "Anisotropic". | **LANDED, port-only.** Build clean. **Owed:** eyeball at 16× on a grazing surface (Depot roof / Dam walkway) vs 1×. | -| D213 | **On-screen FPS readout — `Video.DisplayFPS` (M-83 QoL wave, port-only, PD parity).** `port/src/optionsoverlay.c` samples frame time once per emitted frame (`fpsTick()` via `sysGetMicroseconds()`, ~0.5 s window) and, when enabled, emits a small top-right green "N FPS" DL even while the F10 panel is closed. Config-only knob (kept off the 13-row panel, which is at its documented layout limit — matches PD, whose `DisplayFPS` is also file-only). **Default 0 ⇒ `optionsOverlayEmit()` still returns NULL when the panel is closed ⇒ golden dumps byte-identical.** | **LANDED, port-only.** Build clean; `bunker1` no-op confirmed. **Owed:** eyeball that the counter reads a sane ~30 and doesn't overlap the HUD. | -| D214 | **Keyboard rebinding — `[Input.Bind]` config section (M-83, port-only, PD parity, Phase 4 debt).** `port/src/input.c` gains 12 gameplay actions (Forward/Back/StrafeLeft/StrafeRight/TurnLeft/TurnRight/Fire/Aim/Action/Cancel/LeanLeft/Start), each a comma-separated list of up to 4 SDL scancode names (`Input.Bind.Forward = W,Up` …). `inputRebuildBinds()` (called from `inputInit()`, after `configLoad()`) parses them via `SDL_GetScancodeFromName`; unknown names log a warning and are skipped. The old hardcoded `keyDown(ks, SDL_SCANCODE_*)` block in `inputComputePad` is replaced by `actHeld(ks, IA_*)`. Mouse buttons (fire = LMB, aim = RMB) stay hardwired; the mouse-wheel weapon-cycle A-pulse is untouched. **Defaults reproduce the previous FPS layout exactly — verified: all 20 default key names round-trip to the identical `SDL_Scancode` the old code used (`SDL_GetScancodeFromName` test, 0 mismatches).** Config-file only (no in-overlay text entry — matches PD, whose rebinding is also file-driven); a fresh `ge007.ini` gets the full `[Input.Bind]` block with the defaults visible. | **PARTIAL — M-84: code PASS (alt/ctrl); one doc-only fix.** LANDED, port-only, no `#ifdef PORT`; build clean. One doc bug fixed (no code change): `config.c` groups keys by the substring *before the last `.`*, so the section header is **`[Input.Bind]`**, not `[Bind]` — earlier finding/commit/QOL text was wrong. Working syntax: put `Fire = Left Alt` under `[Input.Bind]`, or write a fully-qualified `Input.Bind.Fire = Left Alt` line anywhere (`config.c:307`). Separately: the pause→**watch menu** does not wire Esc→back (still Enter to open/close/back) — pre-existing, `options.c`, minor. | -| D215 | **1P weapon viewmodel never drew in-level — `gunRenderFirstPersonGunModels` builds its `ModelRenderData` from a reinterpret across separately-declared adjacent globals that only works on N64 (M-83, D3x/ABI class; retires VIEWMODEL-RESEARCH.md).** The N64 line `renderdata = *(ModelRenderData *)&D_80035CC0;` (`gunfire.c`) casts the lone `u32 D_80035CC0 = 0;` to a whole `ModelRenderData` and reads on into the next declared global, `u32 D_80035CC4[] = {1, 3, 0, 0, …}` (`gun.c`) — yielding `{ basemtx=0, zbufferenabled=1, flags=3, rest=0 }` **only because the N64 linker lays the two globals out contiguously in declaration order and pointers are 4 B**. On x86-64 it breaks twice: `ModelRenderData`'s three pointer members (`basemtx`/`gdl`/`mtxlist`) widen 4→8 B so `flags` is no longer at struct offset 8, and C guarantees nothing about the two globals' relative placement. Measured (`GE_DVM=1`, BUNKER1): `renderdata.flags == 0`, so **every** weapon-model DL node was gated off at `modelRenderNodeGundl` (`(renderdata->flags & 1)`), and `subdraw()` for the weapon emitted just its `gSPSegment` — 1 gfx command instead of ~150.

When set it does what every intro stage's own `!is_first_time_on_main_menu` branch does (`front.c`): `is_first_time_on_main_menu = FALSE; prev_keypresses = TRUE; maybe_is_in_menu = TRUE; menu_update = MENU_FILE_SELECT;` — i.e. it reuses the game's own post-intro route rather than inventing one, so the legal screen + Nintendo/Rare/GoldenEye logo attract loop is skipped. `GE_STARTMENU` still wins when both are set. Default 0 ⇒ untouched. | **LANDED + VERIFIED this session.** Build clean. Headless: default boot frame 90 = the TWYCROSS classification screen (10% non-black), `SkipIntro=1` frame 90 = the **SELECT FILE menu** (folders/photos/cursor all render, 89% non-black), no crash across repeated boots. Screenshots captured + eyeballed. **Owed:** nothing critical — a human boot to confirm the menu is fully interactive (cursor moves, a save slot opens). **REGRESSED (v0.2.1 user testing, 2026-09-15): user reports enabling `Skip intro` breaks audio.** Not root-caused this session — leading suspect is that the intro/attract stages perform some audio-subsystem init (title/attract music kickoff, or a first-touch of the mixer) that `portSkipIntro`'s jump to `MENU_FILE_SELECT` bypasses. **Mitigation applied:** the `Game.SkipIntro` row was pulled from the F10 options overlay (`port/src/optionsoverlay.c`) so players can no longer enable it from the menu; the config var, default (0/off), and `lv.c` hook are untouched (so an existing `ge007.ini` with it already set would still trigger the bug — worth a follow-up hard-disable if that turns out to matter).

Signature matches the **D161 family** — a CI-format tile drawn without the expected TLUT state, so fast3d's `import_texture` indexes a **stale `rdp.palette`**. D161 fixed the explicit `G_TT_NONE` case; this looks like model DLs not emitting `gDPLoadTLUT` through the port path, or the palette segment not resolving for weapon/character geometry. **Not a D215 regression** — D215 only un-gated the DL. | **FIXED (M-90/M-92/M-97; PR #47 texpool alignment + PR #49 CI-cache palette key) — the green-texture defect is fixed and merged, confirmed by two independent human playtests. The white missing-texture residual (AK47 / NPC-held world-model weapons) is split out as D228.** Status cell had gone stale at OPEN; corrected M-105. History: root cause characterised M-86; headless repro: `-level_34` FACILITY ~frame 300–400, PP7 **grip = flat green block** + green ring at the barrel joint + green-cast hand; barrel/slide upper correct black. Also green on `-level_30` DEPOT. **Clean on `-level_09` BUNKER1** (A/B control — same PP7, identical DL). **Two separate defects found:** ① **Wrong palette bound (the visible green — upstream of fast3d).** The grip is a CI4 solid-fill of palette index 0. Green `(24,65,0)` == RGBA5551 `0x1A00` == `rdp.palette[0]` at grip-import time. The grip's `count=1` model `G_LOADTLUT` is fed **different source bytes per level** for the same tile: BUNKER `00 01`→`PD_BE16`→`0x0001` (black ✓), FACILITY `1a 00`→`0x1A00` (green ✗). fast3d byteswaps + stores faithfully (proven correct by BUNKER) — the wrong bytes *arrive* from the model-DL / segment-address path. Strong tell: every *larger* model TLUT has `raw[0]==raw[1]==0x0000` with real colour from index 2 ⇒ GE's model-TLUT payload likely carries a **4-byte (2-entry) leading zero pad**, OR the port's model-TLUT source pointer is **4 bytes / 2 entries too low** (then the `count=1` grip load reads the tail of the preceding CI blob — BUNKER lucky, FACILITY not; fits "widespread across levels + weapons"). Ruled out this session: not tail-overflow (index 0 is in-range; matches M-85 `GE_D217Z`), not the fast3d byteswap. **Next:** dump the grip TLUT `G_SETTIMG` target vs the ROM/`pcmodels` sidecar PP7-grip material bytes; confirm the 4-byte offset vs N64; fix in model-DL segment resolution or `tools_pc/d43_emit.py` blob placement (sidecar regen). ② **CI texture-cache collision (proven, real, separate; fix landed).** `gfx_texture_cache_lookup` (`gfx_pc.cpp:522`) keyed CI textures on `{addr, palette_addrs[0/1], palidx, size_bytes}` with **no palette-content check**; GE reissues `gDPLoadTLUT` from repeated scratch-arena addresses with different content, so a later material could take a stale HIT and sample another material's decoded palette. **Fix on branch `fix/d217-model-texture-palette` (commit `f6fc0399`):** FNV-1a hash of the 512-byte `rdp.palette` computed only in `gfx_dp_load_tlut()`, added to the CI cache key (`port/fast3d/gfx_pc.{cpp,h}`, fast3d-internal, no `#ifdef`). Cheap, cannot worsen a decode; **owes a full 21-level `verify.sh sweep`** before merge (touches every palettized world texture's import path — cache-churn risk only). Does **not** fix defect ①. Screenshots: session scratchpad `d217/`, `fac_gun_crop.png`. Cross-ref `docs/dev/GRAPHICS-BACKLOG.md`. **User playtest matrix (M-87, raw notes — not yet triaged):** DAM/PPK: watch still green; AK47 viewmodel has white (missing-texture) patches on the magazine + barrel. FACILITY: PPK garbled **green AND blue**; 3rd-person Bond world model shows greenness on level load-in; AK47 has "weird blue / glitched" textures. JUNGLE: M16 viewmodel is orange in spots. Confirms multi-weapon (PP7/AK47/M16), multi-color (green/blue/white/orange) — consistent with the upstream model-TLUT-source theory (different trailing garbage per weapon/material) rather than one single fixed offset. **Scope clarified (M-87):** not just Bond's 1P viewmodel / 3P world model — **NPC-held weapon models (other characters' guns in third person) show the same glitched-color/white-missing texture symptom.** So the defect is in the shared weapon-model-DL/TLUT path used by *any* character holding that weapon, not something specific to Bond's model or the 1P viewmodel rig — widens the likely fix surface (weapon model loading in general) beyond "Bond's gun." **M-87 clarification:** not uniform across levels — severity and glitch *type* both vary per level (some levels show it lightly, some not at all in a given session, and the specific wrong-color/missing pattern differs), consistent with the per-material trailing-garbage theory rather than one fixed global offset. **M-88 update: defect ① is NOT a `tools_pc/d43_*.py` sidecar bug — the theory in this row is refuted; the model converter never touches texture/palette bytes at all.** Root cause narrowed to the runtime `texWriteLoadToTmemAddr`/`gfx_dp_load_tlut` TLUT-address path (`src/game/tex.c` + `port/fast3d/gfx_pc.cpp`, both out of this session's file scope). See full write-up: §H "D217 — M-88 defect ① root-cause narrowing". **M-89 update: the `gfx_dp_load_tlut` pitch/width=1 hypothesis is REFUTED** (hand-derived: it already computes `pitch=1` for every model-DL TLUT call via the GBI `width-1` packing — a proposed `pitch=1` patch would be a no-op, do not apply it) — **the addressing math is correct by inspection**. New leads, neither yet probed: (a) does `g_Textures[texturenum]`/`_imagesSegmentRomStart` actually resolve to identical ROM bytes for this weapon's grip texture on BUNKER1 vs FACILITY (an image-table/asset-resolution path distinct from the already-ruled-out per-model `TextureID`/`d43_emit.py`/`Globalimagetable`/D68 path), or (b) does the shared `texpool` arena (`image.c` `texLoad`, two-ended `leftpos`/`rightpos` allocator) serve a stale/aliased `tex->data` for what should be a fresh per-level decode. See full write-up: §H "D217 — M-89: the `gfx_dp_load_tlut` width=1/pitch hypothesis is REFUTED". **M-90: defect ① ROOT CAUSE FOUND + FIXED** — neither lead (a)/(b) was it: the texpool arena base for the weapon pools lands **%8==4 on PC** (memp bump drift from pointer-bloat allocation sizes), and `texAlignIndices` pads CI rows to *absolute* 8-byte boundaries, so every palette in a misaligned pool sits **4 bytes early** while the model-DL `G_LOADTLUT` still reads the N64 offset — the grip's count=1 load lands on the next tenant's header slot (`texnum=26` → LE s16 → `0x1A00` = the green), and larger loads read two zero-pad entries then the real palette (this is M-86's unexplained "leading zero pad" tell). **Fix:** `texInitPool` rounds the arena base up to 8 under `#ifdef PORT` (no-op on N64; ≤7-byte pool shrink) — ABI/layout-class edit, no logic touched. Verified: FACILITY 188/188 decodes aligned + draw reads `pal0=0001` (was `1a00`) + 0 green pixels in frames 250–450 (was ~1300); BUNKER1 + DEPOT still clean. **Pending:** full 21-level sweep result + human playtest eyeball of the M-87 weapon matrix. See §H "D217 — M-90". **M-92: sweep 21/21 PASS + human eyeball done — PP7/PPK/watch CONFIRMED FIXED by this alignment fix. AK47 (viewmodel + world model) and NPC-held world-model weapons (white/missing-texture patches, e.g. magazine/receiver) are a DISTINCT, still-OPEN residual — not fixed by this PR, not yet root-caused. PR #47 should still merge (real, confirmed partial fix); reopen defect ① scoped to the AK47/NPC-world-model white-texture failure mode. See §H "D217 — M-92". **M-97: independently re-confirmed by a second human playtest** (this branch merged up to date with `main`, fresh build, `-level_34` FACILITY): PP7/PPK grip+hammer clean, watch face clean, no green anywhere; **NPC-held AK47 still shows white missing-texture patches.** Two independent playtests, same split — the green defect is fixed, the white defect is not. The white residual is now split out under its own label, **D228** (rather than leaving defect ① ambiguously half-open), so this row can close on the green mechanism it actually describes. | -| D218 | **Wide FOV exposes the per-level draw-distance / fog boundary — "blue artifacting" down long peripheral sightlines (M-84, user QA on the D211 FOV slider).** BUNKER→**Dam main tunnel** at `FovScale` ~150: geometry / backdrop past the level's fog-end distance shows at the widened frustum edges (blue = Dam's fog tint). Not a render bug — `fogLoadCurrentEnvironment` (`bgfog.c:305`) does `viSetZRange(Visibility.BlendMultiplier, Visibility.FarFog)`, so **`Visibility.FarFog` is both the far clip plane and the fog-saturation distance**; levels tune it for the stock ~60° FOV. | **Logged (M-84), fix proposed + parked.** Plan: `Video.DrawDistance` (percent, 100–400, default 100 ⇒ no-op) `#ifdef PORT` multiplier on `FarFog` at `bgfog.c:305` (+ the direct `arg0->Visibility.FarFog` reads just below, so fog stays consistent) plus `Video.DrawDistanceAutoFov` (0/1, default 1 — couples draw distance to `FovScale` unless `DrawDistance` is set explicitly). Clamp effective multiplier ≲2.5× (small znear ⇒ far-field z-fighting risk). **M-87: user confirms still occurring** at high FOV, and — reversing the earlier "not implemented by user request" — **now wants `Video.DrawDistance` implemented as a real QoL feature**, plus scope it to cover **LOD/detail-distance in general**, not just the fog/far-clip boundary this row root-caused. Open question for that broader ask: does GE have a *separate* geometry/object LOD-swap or draw-culling distance mechanism (distinct from `Visibility.FarFog`) worth exposing too, or is fog-distance the only meaningful "how far can you see" knob in this engine? Check for a per-object visibility-radius / simple-model-swap system before assuming `FarFog` is the whole story. **FIXED as designed, awaiting visual verification (M-121).** Implemented exactly the parked plan: `f32 portDrawDistanceMultiplier(void)` (`port/src/video.c`) — an explicit `Video.DrawDistance != 100` wins outright, otherwise `Video.DrawDistanceAutoFov` (default on) couples the multiplier 1:1 to `Video.FovScale`, clamped to `[1.0, 2.5]` (never shrinks draw distance; the 2.5x ceiling is the finding's own far-field z-fighting caution). Applied in `fogLoadCurrentEnvironment` (`bgfog.c`) to a new local (`scaledFarFog`) used at *both* the `viSetZRange` far-clip call and the `g_CurFogDetails.scaled_far_fog_dist` fog-blend read just below it, so the clip plane and the fog math stay consistent per the original plan's own note — the level's `EnvironmentRecord` itself is never mutated (it's shared/reloaded, not a per-frame copy). Both new config keys added to the F10 overlay (`Video.DrawDistance` slider, `Video.DrawDistanceAutoFov` toggle) alongside the existing `FovScale` row. Identity at both defaults (`DrawDistance=100`, `FovScale=100` ⇒ `portFovScale==1.0f`) by construction. **Broader LOD-swap question from M-87 ANSWERED — yes, and now exposed too (same session, M-121 continued).** `src/game/model.c` has a real, distinct geometry-LOD system: `MODELNODE_OPCODE_LOD` nodes whose children are shown/hidden per-frame by `modelUpdateDistanceRelations()` testing a view-space `distance` (scaled by `getPlayer_c_lodscalez()`, itself now FOV-consistent per this session's D222 fix) against each node's `MinDistance`/`MaxDistance` — a genuine detail-swap mechanism, separate from the fog-visibility-fade this row already fixed. It even has an existing ground-truth multiplier hook, `g_ModelDistanceScale`, already used transiently by the game itself (`chr.c`'s 0.3125f close-up override, `front.c`/`title.c`'s menu-model `modelSetDistanceDisabled`). Rather than write to that shared global (would fight those existing overrides), added a second, composed multiplier at the same call site: `f32 portLodDistanceMultiplier(void)` (`port/src/video.c`), driven by new `Video.LodDistance` (percent, 25-400, default 100) and `Video.LodDistanceAutoFov` (**default OFF**, unlike `DrawDistanceAutoFov` — this is meant as a standalone performance lever the user can pull *down*, not something that silently adds cost as FovScale widens) — `distance *= portLodDistanceMultiplier()`, inverse-scaled so `LodDistance=200` keeps full detail twice as far (more cost) and `LodDistance=50` drops to the lower LOD twice as soon (less cost). Both new keys in the F10 overlay alongside `DrawDistance`. Identity at `LodDistance=100`. Rebuilt clean, crash-free at `LodDistance=40` (aggressive) on Dam and at defaults on bunker1. **M-121 live playtest, iterated to a working state.** Two real issues found and fixed while testing live on Dam with the user: (1) **regression** — the D222 fix (above) correctly widened `c_lodscalez` for the screen-edge cull planes, but that same value is *also* read directly by `propobj.c`'s `chrobjFogVisRangeRelated()`/`sub_GAME_7F054C58()` (the character/prop fog-visibility-fade cutoff) — uncompensated, this made guards fade/disappear *sooner* at wide FOV than before D222, the opposite of the intent. Fixed by dividing that same `c_lodscalez` reading by `portDrawDistanceMultiplier()` at both call sites (`#ifdef PORT`), so the "how far can you see" question these two share is answered consistently. (2) **tuning** — a straight 1:1 `Video.FovScale` auto-coupling on `portDrawDistanceMultiplier()` was not aggressive enough; live-tested up twice (1x → 2x → 4x `FovScale`, clamp ceiling raised 2.5x → 4.0x → 6.0x each time) before guards held up and the Dam tunnel's blue-glow artifact receded to the user's satisfaction. Re-verified end-to-end that the fog *ramp* itself (not just the far-clip cutoff) scales with the multiplier — `g_ScaledFarFogIntensity`/`scaled_far_fog_dist` both derive from the same scaled far value — so if a similar artifact resurfaces on another level, the multiplier magnitude or a level-specific tunnel-length edge case are the first things to check, not this math. **User confirms this is good for now.** All three (D222 cull fix, D218 draw-distance + fog-visibility-fade fix, D249 LOD-distance) verified crash-free and landing in the same PR. | -| D219 | **PPK explosions render purple on Dam (M-87, user QA, "not 3D but noting").** Effect-color defect, not a texture-decode one — likely the D172 particle-color family (`gfx_lod_tile_offset` / `G_CC_INTERFERENCE` channel-order class) recurring on a different particle type/weapon than the D172 fix covered, or a fresh instance of the same class. | **RESOLVED (M-115, 2026-09-12)** — byte-order fix in `src/game/image.c` scoped by pixel format (16-bit family bswap16-at-store, 32-bit identity); user playtest-confirmed.

If still purple after D172's fix (which the user's Dam report postdates — needs re-confirming on current `main`), the next suspect is the GLSL combiner implementation of `G_CC_INTERFERENCE`+`G_CC_MODULATEIA2` for cycle 2 specifically (`gfx_generate_cc`, `port/fast3d/gfx_pc.cpp:312-494`), not the tile-offset fix. **Next, concrete:** run Dam (`-level_33`) with `GE_D172=1` while triggering a PPK/grenade explosion and check for "BUG" lines in the log (silence = D172's fix already covers this DL and the row can likely close on a re-test; needs a scripted-fire repro, not yet built). **M-90 runtime re-check DONE (scripted-fire repro built with `GE_INPUTSCRIPT`): the D172 fix demonstrably covers Dam's particle DLs — row can close on a human by-eye pass.** Ran `-level_33` headless with `GE_D172=1`, 64 scripted Z-pulses (`GE_INPUTSCRIPT="200:Z;215:Z;..."`, ~15 controller-reads apart) and a `GE_PCDUMP` window over the same span. Result: **40/40 particle multitex tris log `SAMPLED1=tile1 (tmem=392)`** — the correct RGBA fire tile, i.e. exactly the post-D172-fix behaviour (pre-fix these read `SAMPLED1 = tile0 (tmem=0 fmt=IA)`, the smoke texture); **zero** "BUG"/unknown-GBI/D146-abort lines; **0** purple/magenta pixels (`r>120, b>120, g<90, r-g>50, b-g>50`) across all 28 captured frames. Caveat: the user's M-87 "purple" report may predate the D172 fix on their binary (playtests run on whatever build was current); this re-check proves the sampling path is correct on current `main`, which is as far as a headless pass can take it — a final by-eye look at a live Dam PPK firefight is the honest closer (cheap for the user, folds into the D217 PR #47 playtest). **M-108 — REOPENED, the by-eye closer FAILED.** User played a live Dam (`-level_33`) PPK firefight on the current `main` build (post-D233/D234 fixes, same session as D243) and confirmed explosions are **still blue/purple**, directly contradicting M-90's clean scripted-repro result (40/40 correct-tile samples, 0 purple pixels, 28 frames). This means the M-90 `GE_INPUTSCRIPT` scripted-fire repro was very likely **not exercising the same explosion instance/DL the live firefight hits** — plausible gaps: a different explosion variant (grenade vs. bullet-impact spark vs. enemy-death vs. PPK-specific muzzle/hit effect) using a DL the scripted test's Z-pulses didn't trigger, or a state/lighting/prim-color condition (M-89's alternate suspect: the `G_CC_INTERFERENCE`+`G_CC_MODULATEIA2` cycle-2 GLSL combiner implementation, `gfx_generate_cc`, `port/fast3d/gfx_pc.cpp:312-494`) that only manifests under conditions the synthetic repro didn't reproduce. **Do not trust the M-90 all-clear for this finding going forward** — it proved one particle path clean, not that Dam's live-fire purple is fixed. Next: a live `GE_PCDUMP`/`GE_D172=1` capture during an actual purple explosion in real play (not a scripted approximation) is now the only way forward — need to pin down exactly what triggers it (PPK gunshots hitting a surface/enemy? a thrown/tossed explosive? which). **User has now confirmed (2026-09-12) this is NOT Dam-exclusive — game-wide, not just suspected.** Treat as confirmed scope, not pending a second-level check. **User wants this actively fixed, not just triaged** — next session should prioritize a live `GE_PCDUMP`/`GE_D172=1` capture during a real explosion (any level) over further static analysis, since the M-89/M-90 static passes are exhausted on this finding without producing a fix. **New HIGH-interest lead (M-110): `explosion.c` never clears `G_LIGHTING` before drawing any of the 15 particle DLs** (`globalDL_0x078` through `0x9a8` in `assets/oddtextures.c`, all structurally identical, all `G_CC_INTERFERENCE`+`G_CC_MODULATEIA2`) — grepped every particle-draw call site in `explosion.c` (`gSPClearGeometryMode` calls at lines 883/1495/1718/2227 only ever clear `G_CULL_BOTH`/`G_FOG`/`G_CULL_FRONT`, never `G_LIGHTING`) and confirmed `G_CC_INTERFERENCE,G_CC_MODULATEIA2` is used nowhere else in the codebase, so it's safe to key a probe on it. The port's vertex path (`port/fast3d/gfx_pc.cpp:1301-1346`) branches hard on `rsp.geometry_mode & G_LIGHTING`: if lighting is on when these particles draw, the authored RGBA tint in `v->v.cn[]` gets reinterpreted as a normal vector, and the resulting SHADE color (fed into `G_CC_MODULATEIA2`'s `COMBINED*SHADE`) becomes a scene-light color instead of the DL's actual red/orange fire tint — a mechanism that would plausibly read as "wrong color, state-dependent, game-wide" exactly as reported, and would explain why a synthetic scripted-fire repro (M-90, no nearby lit models) came back clean while live firefights (guards/lit models on screen) don't. **Not yet confirmed** — this depends on whatever last touched `geometry_mode` before the particle draw in a given frame, which the game's own N64-accurate command order controls; it is not yet established whether this is a genuine port bug (fast3d misordering/dropping a `G_GEOMETRYMODE` command relative to real hardware) or something that would reproduce identically on N64 (in which case it isn't actually the D219 mechanism, since N64 doesn't show purple explosions). **Instrumented, not fixed:** added a `#ifdef PORT`/`GE_D172=1`-gated log line to the existing D172 multitex-tri probe (`port/fast3d/gfx_pc.cpp` ~line 1740, `gfx_sp_tri1`) that now also prints `geometry_mode` and flags `LIGHTING=ON <-- D219 SUSPECT` whenever one of these particle triangles draws with lighting on. Sanity-checked against the known-clean M-90 repro (headless `-level_33`, 40 scripted Z-pulses): probe fires exactly 40/40 as before, all show `LIGHTING=off` — consistent with the already-known-clean case, confirming the probe works and doesn't false-positive. **Next, concrete:** run `build-pc/d172_silo.bat` (or equivalent, `GE_D172=1`) and trigger a real explosion (any level, any explosive source) near visible character models; grep the log for `D219 SUSPECT`. A hit confirms the mechanism and turns this into a real fix (clear `G_LIGHTING` in the port's particle-draw path or in fast3d's geometry-mode tracking, whichever turns out to be the actual divergence from N64); a miss across a real purple-explosion capture rules this whole lead out. **M-112 (this session): decode-chain code review + two new inert diagnostic probes; runtime capture NOT obtained (environment limitation, see below). Confidence: LOW-MEDIUM on a narrowed next step, no fix applied.** Read the full N64 texture decompression ground truth for these assets end to end: `texLoadFromDisplayList`→`texLoad`→`texInflateNonZlib`/`texInflateZlib`→(`texReadUncompressed` | `texInflateHuffman`/`texInflateRle`+`texChannelsToPixels` | `texBuildLookup`+`texInflateLookup`/`texInflateLookupFromBuffer`) (`src/game/image.c`), plus `gimgFixupGlobalimagetable`/`gimgSyncCompiledGlobalDLs` (`port/src/gimgfixup.c`) and `import_texture_rgba16` (`port/fast3d/gfx_pc.cpp:653-681`). Findings: (1) `IMAGE_FIRE_0..14` are **not** `sImageTableEntry`-table images (unlike `IMAGE_IMPACTMULTI`/`IMAGE_IMPACTREDBRICK*`/flare/ammo images, which live in the 32 `sImageTableEntry` arrays at segment offset 0xAC8+ and get their `G_SETTIMG` marker synthesized at runtime by `texSelect`, `src/game/othermodemicrocode.c:318`) — FIRE_N's `gsDPSetTextureImage(...IMAGESEG(IMAGE_FIRE_N))` is baked directly into the compiled `globalDL_0x078..0x9a8` display lists (segment offset 0x000-0xA50) alongside the interleaved, correctly-rendering `IMAGE_SMOKE_0..14` (IA16). Both FIRE's and SMOKE's markers go through the *same* `gimgFixupGlobalimagetable` part-1 DL-bswap step and the *same* `texLoadFromDisplayList`→`texLoad` resolution — no separate/divergent table-offset math applies to FIRE_N specifically (this narrows away part of the open brief's option (a): there is no `sImageTableEntry`/`s_tbl_offs[]` bounds bug possible here, because FIRE_N never goes through that array class at all). (2) `texChannelsToPixels`'s `TEXFORMAT_RGBA16` case and `texReadUncompressed`'s `TEXFORMAT_RGBA16` case are decomp ground truth (byte-exact, `#ifdef PORT` free) and are format-generic, not texture-specific — a bug there would require a same-format sibling to also be wrong, and IMPACT/FLARE RGBA16 sprites (same `G_IM_FMT_RGBA,G_IM_SIZ_16b`, same underlying `texLoad`) are the only same-format comparison point on hand, **but this session did not runtime-confirm whether those actually render correct colors in game** — flagging as an unverified assumption inherited from earlier sessions' "shared decoder is proven correct" framing, not re-proven here. (3) `texSwapAltRowBytes` is already an unconditional no-op on `PORT` (D159, `src/game/image.c:2219`, `return;` before any format switch) so it cannot be format- or texture-selective on the port — ruled out as a contributor for FIRE specifically (it's equally a no-op for every other texture). **New, added, NOT yet exercised:** two matching `GE_D219RAW`-gated diagnostic probes (inert unless the env var is set, `#ifdef PORT`, no behavior change): (a) in `texInflateNonZlib` (`src/game/image.c`, right after the per-image header read, and again right after decode) — logs `texnum`, `format`, `width`, `height`, `compmethod` from the bitstream header, then the first row of decoded RGBA5551 pixel words, for every image shaped 16x14 (the FIRE tile shape); (b) in `import_texture_rgba16` (`port/fast3d/gfx_pc.cpp`) — logs the same pixel words as read back at upload time, so a session can diff "as decoded" vs "as consumed" to rule pool corruption/mis-addressing in or out. **Environment blocker hit this session:** could not get the built `ge007.x86_64.exe` to produce *any* stderr/log output when launched from this delegated agent's shell, across four different invocation strategies (direct foreground exec, backgrounded `&`/`nohup`, `cmd /c start foo.bat` detached, `cmd /c foo.bat` synchronous with a hard timeout) — the process either exits or is killed before a single `osSyncPrintf`/`sysLogPrintf` line reaches the redirected log file, even though every print call in this codebase does an explicit `fflush(stderr)`. A plain GUI sanity check (launching `notepad.exe` the same way) worked fine, ruling out a blanket "no GUI" sandbox restriction, so the failure is specific to this binary/environment combination and its cause was not identified. Per `env-no-runtime-verify` (session memory): runtime verification is session-dependent; treat this session's empty captures as inconclusive, not as evidence of anything. **Next, concrete (for a session that CAN capture runtime output, interactive or otherwise):** (i) run any level with `GE_D219RAW=1` during an explosion/PPK firefight (or simply on level load, since these are likely eagerly cached) and read the logged `compmethod` for `IMAGE_FIRE_N` — cross-reference against a `GE_D219RAW`-instrumented capture of a *confirmed-correct-on-screen* RGBA16 sprite from the sibling `sImageTableEntry` families (e.g. `IMAGE_IMPACTMULTI`) to see whether FIRE uses a different `TEXCOMPMETHOD_*` (the compressed-bitstream compression method, not the pixel format) than a texture confirmed to render correctly — `TEXCOMPMETHOD_LOOKUP`/`_HUFFMANLOOKUP`/`_RLELOOKUP` (`texBuildLookup`+`texInflateLookup*`) build/consume a packed-color lookup table with a completely different bit-layout code path than `_HUFFMAN`/`_HUFFMANPERHCHANNEL`/`_RLE` (`texChannelsToPixels`, per-plane R/G/B/A order); if FIRE's method differs from the working comparison texture's, that pinpoints exactly which decode function to scrutinize next, rather than continuing to treat "the RGBA16 decoder" as one monolithic suspect. (ii) if the compmethod matches, the bug is genuinely upstream of decode (ROM/asset-extraction data itself, not the decompression code) — at that point compare the decompressed byte stream against a reference N64 emulator's texture-dump of the same asset (this repo has no such reference on hand) to establish definitively whether the ROM bytes for FIRE really do decode to blue/purple on real hardware too (in which case the bug is actually downstream in the color-combiner path after all, reopening the D172/G_CC_INTERFERENCE lead this session did not have budget to re-examine) or whether the extraction into this repo's `assets/oddtextures.c`-adjacent ROM data diverges from the real cart image for just these 15 offsets. Probes left in tree, both inert by default: `GE_D219RAW` (`src/game/image.c` `texInflateNonZlib`, `port/fast3d/gfx_pc.cpp` `import_texture_rgba16`). **M-141: Steam Deck playtest confirmation, widened symptom scope** — user reports "blood is purple, shots on body are blue/green" (general, not tied to a specific level in the report). Blood/hit-decal color is a new specific instance beyond this row's tracked "PPK explosions"/"particle effects" framing — same RGBA16/particle-color neighborhood as D172/D252, worth keeping in mind together rather than as three unrelated color bugs; whichever gets a real runtime capture first (this row's own `GE_D219RAW` probe, or D252's `GE_D252`) should also check blood decals specifically. | +| D173 | **Third-person Bond model spawns too high** — full `## D173` entry at file tail | OPEN — observed, not investigated.… | +| D179 | **Packaged build crashes after the logos — the D43/D69 model + bg sidecars are ROM-derived and absent from any build that has no ROM (M-34, alpha-release QA).** — full `## D179` entry at file tail | Diagnosed, not fixed — release packaging gap + latent `romdata.c` fallback | +| D180 | **Native-PC input pass (M-XX QoL run, `qol/native-pc-input-menu`, port-only).** — full `## D180` entry at file tail | LANDED, port-only, no `#ifdef PORT`.… | +| D181 | **`Game.ScreenShakeIntensity` — first route-(b) `src/` gameplay-cosmetic hook (M-XX QoL run).** — full `## D181` entry at file tail | **Menu row pulled (v0.2.1, user testing).** The hook is correct on its own narrow terms —… | +| D184 | **F10 port-layer options overlay — the approach-(C) surface from `OPTIONS-MENU-PLAN.md` (M-37).** — full `## D184` entry at file tail | **LANDED, port-only, no `#ifdef PORT` in `src/`.** Build links 241/241.… | +| D211 | **PC FOV slider — `Video.FovScale` (M-83 QoL wave, port-only, `WIDESCREEN-FOV-PLAN.md` Phase 4).** — full `## D211` entry at file tail | **PARTIAL — M-84 refix… | +| D212 | **Anisotropic-filtering config wiring — `Video.Anisotropy` (M-83 QoL wave, port-only).** — full `## D212` entry at file tail | **LANDED, port-only.** Build clean. **Owed:** eyeball at 16× on a grazing surface (Depot roof / Dam walkway) vs 1×. | +| D213 | **On-screen FPS readout — `Video.DisplayFPS` (M-83 QoL wave, port-only, PD parity).** — full `## D213` entry at file tail | **LANDED, port-only.** Build clean; `bunker1` no-op confirmed. **Owed:** eyeball that the counter reads a sane ~30 and doesn't overlap the HUD. | +| D214 | **Keyboard rebinding — `[Input.Bind]` config section (M-83, port-only, PD parity, Phase 4 debt).** — full `## D214` entry at file tail | **PARTIAL — M-84: code PASS (alt/ctrl); one doc-only fix.** LANDED, port-only, no `#ifdef PORT`; build clean.… | +| D215 | **1P weapon viewmodel never drew in-level — `gunRenderFirstPersonGunModels` builds its `ModelRenderData` from a reinterpret across separately-declared adjacent…** — full `## D215` entry at file tail | **FIXED (`src/game/gunfire.c`, `#ifdef PORT`).** Build clean.… | +| D216 | **`Game.SkipIntro` — boot straight to the file-select menu (M-83, port + one `#ifdef PORT` game-code line, PD parity, Phase 4 quick win).** — full `## D216` entry at file tail | **LANDED + VERIFIED this session.** Build clean.… | +| D217 | **1P weapon viewmodel + 3P Bond model textures garbled — wrong/stale palette on model-DL CI textures (M-84).** Two defects: ① texpool arena misalignment (the green), ② CI texture-cache collision. — full `## D217` entries (M-86→M-97) at file tail | **FIXED + merged** (PR #47 + PR #49); white residual split out as D228. | +| D218 | **Wide FOV exposes the per-level draw-distance / fog boundary — "blue artifacting" down long peripheral sightlines (M-84, user QA on the D211 FOV slider).** — full `## D218` entry at file tail | **Logged (M-84), fix proposed + parked.** Plan… | +| D219 | **PPK explosions render purple on Dam (M-87, user QA, "not 3D but noting").** — full `## D219` entry at file tail | **RESOLVED (M-115, 2026-09-12)** —… | **M-111 (2026-09-12, live session, 6 build/relaunch cycles): G_LIGHTING lead RULED OUT; texture-cache-collision lead RULED OUT; ROOT CAUSE FOUND — R/B channel swap in the decoded fire particle texture data itself.** Live-captured 4 rounds against a real user playtest (not scripted) with the user confirming explosions were still blue/purple in every capture: 1. **G_LIGHTING probe fired 5000+ times across a full playtest with explosions triggered, 100% `LIGHTING=off`, 0 `D219 SUSPECT` hits.** (First attempt used the original 40-hit cap from the D172 probe, which silently exhausted on ordinary bullet-impact particles before any explosion — fixed to exempt the lit case from the cap and add an always-on periodic counter, confirming the code path really was being hit throughout, not just early. See `port/fast3d/gfx_pc.cpp` `gfx_sp_tri1`'s D172/D219 probe block.) **G_LIGHTING is conclusively not the mechanism.** @@ -461,115 +472,115 @@ covers D24–D69; the log continues in §H (D32 procedure, D70–D121). 2. **Confirmed empirically, not just by inspection:** dumped raw decoded RGBA5551 words at the exact point `texChannelsToPixels`/`texInflateLookup` write them (`GE_D219RAW=1`, Dam `-level_33`, scripted PPK fire via `GE_INPUTSCRIPT`) — e.g. pre-fix texnum 2111 decoded word `0xf1c2` (R=30,G=3,B=1 under standard RGBA5551 — briefly looks *plausible* red until you realize this is the value BEFORE the byte-swap fast3d applies; the two-stage mis-cancellation is what produced the reported blue/purple, not a one-step swap — see the fix verification below for the real signal). The conclusive test is the rendered/uploaded texture, not the intermediate value in isolation. 3. **Fix (`src/game/image.c`, `#ifdef PORT`/`#else` macro, no `src/` logic changed):** added `PORT_PIXEL16`/`PORT_PIXEL32` — `__builtin_bswap16`/`32` under `#ifdef PORT`, identity under `#else` (so the N64 build is byte-for-byte unaffected, verified by inspection: the macro is a no-op expansion, not a code path change) — and wrapped every wide-pixel (`RGBA32`/`RGB24`/`RGBA16`/`IA16`/`RGB15`) store in the five functions listed above. CI/I4/I8/IA4/IA8 branches (single-byte, no byte order) are untouched. This is the D3x/AGENTS.md#2 narrow ABI/byte-layout exception class: mechanical, semantics-preserving (same numeric color, corrected byte order for the LE host), scoped to exactly the format cases that need it. 4. **Verified, numerically and visually:** `GE_TEXDUMP=1` PPM capture of the 15 `IMAGE_FIRE_N` textures post-fix — average RGB flipped from B-dominant (M-111: `fire000 (102,67,138)`) to R-dominant (post-fix `fire000 (141,127,53)`, `fire003 (147,81,24)`, `fire005 (47,10,2)`); a 10x-upscaled render of one frame and a 6-frame animation strip (frames 000-006, session scratchpad) show a clean, unambiguous fire-sprite animation — bright yellow-white core cooling through orange to red/black ash, exactly the expected in-game fire look, no purple/blue anywhere. Sanity-checked a montage of 12 ordinary (non-fire) world textures from the same Dam capture (clouds, hazard stripes, pipes, grating, concrete) — all render correctly, no regression from the format-gated change. `-level_09` (BUNKER1) and `-level_33` (Dam) both boot and render crash-free post-fix (10s+ each, no `ge007.crash.log`). **Not yet done:** a full 21-level `verify.sh sweep` and a genuine live human playtest confirming the fix in real (non-scripted) gameplay — the scripted-fire + texdump evidence here is strong but the row should stay open until a human eyeballs a real firefight on this build. `docs/porting-notes.md` gets a new entry for this bug class (runtime-decoded multi-byte pixel formats need explicit byte-order handling; static C-array textures already get this via D71/`gfx_tex_normalize_source`, runtime-decompressed ones did not). **M-114 — REGRESSION, reverted.** User playtest after M-113 landed reported 1P muzzle flash rendering blue and the ammo HUD counter rendering pink — colors inverted on textures that were fine before. Root cause: M-113's `PORT_PIXEL16`/`PORT_PIXEL32` swap is applied unconditionally to every call site in `texReadUncompressed`, `texChannelsToPixels`, `texInflateLookup`, and `texInflateLookupFromBuffer` — i.e. to every RGBA16/RGB15/IA16/RGBA32/RGB24 texture decoded through these shared functions, not just `IMAGE_FIRE_N`. This is the exact failure mode already logged above against the sibling function ("do NOT attempt a blanket R/B swap in `import_texture_rgba16` — it's shared by the whole game and would break every correctly-rendering RGBA16 texture"), just repeated one file over. Muzzle flash and the ammo HUD icon evidently decode through this same shared path without needing the swap. **Fix applied:** `PORT_PIXEL16`/`PORT_PIXEL32` reverted to identity (no-op) in `src/game/image.c`; the macro/call-site wrapping is left in place as scaffolding. **D219 is OPEN again** — the fire-particle color bug is unfixed. **Next, concrete, not yet done:** find the actual property that distinguishes `IMAGE_FIRE_N`'s decode from a working same-format sibling (M-112 already narrowed one candidate: FIRE is baked directly into a DL rather than going through the `sImageTableEntry` table that flare/ammo/impact sprites use — confirm whether that DL-embedded path is what needs the swap, or whether it's specifically `compmethod`, per M-112's still-open next step) and scope the macro to that property, not to a hardcoded texnum range. Not runtime-verified this session (static revert only, done to stop an active regression fast) — a human should confirm muzzle flash/ammo colors are back to normal on this build. **M-115 (2026-09-12, delegated session, 3 build/run cycles): fix RE-APPLIED, scoped by GBI pixel format — the M-114 regression resolved by construction, fire fixed again.** Per M-114's brief, found the property that distinguishes `IMAGE_FIRE_N`'s decode from working same-format siblings and scoped the macros to it. (1) **The discriminator is the decoded pixel FORMAT, not compmethod or texnum.** Full offline census of all 2698 ROM image-table entries (`scratch/d219_headers.py`, parsing real bitstream headers with the same MSB-first `texReadBits` contract as `src/game/image_bank.c`; zlib images skipped after the 2-byte `rz` preamble per `decompressdata`): only 94 non-zlib wide-pixel images exist — RGBA16=19, RGB15=14, IA16=1, RGBA32=60. The fire frames span compmethods RLE(4)/LOOKUP(5)/RLELOOKUP(7)/HUFFMANBLUR(8) (confirmed offline AND at runtime), so compmethod cannot scope the fix; a texnum range is a hardcoded landmine. Format IS structural: every 16-bit GBI-size format (RGBA16/RGB15/IA16) is consumed by importers that read the pool as **manually big-endian bytes** (`import_texture_rgba16`: `col16=(addr[0]<<8)|addr[1]`; `import_texture_ia16`: `intensity=addr[0], alpha=addr[1]`), while every 32-bit format (RGBA32/RGB24) is consumed by `import_texture_rgba32`, which does `PD_BE32()` on a **native** u32 load — it expects host-order words. So bswap-at-store is required for exactly the 16-bit family and must be identity for the 32-bit family; M-113's blanket swap hit both (M-114), M-114's full revert broke the 16-bit family again. (2) **Change (`src/game/image.c`, `#ifdef PORT` only, no call-site edits):** `PORT_PIXEL16(x)` = `__builtin_bswap16((unsigned short)(x))`; `PORT_PIXEL32(x)` = `(x)`. Every existing call site already routes by `TEXFORMAT_*` to the right macro, so M-114's scaffolding was already format-scoped per site — only the macro definitions were wrong (both bswapped). 30-line comment at the definition records the importer contract + census. (3) **Runtime verification (Dam `-level_33`, scripted Z-pulse fire via `GE_INPUTSCRIPT`, `GE_D219RAW=1` + `GE_TEXDUMP`/`GE_TEXRAW`):** all 15 fire frames decode at runtime as format=1 (RGBA16) with compmethods 4/5/7/8 exactly matching the offline census (texnum 2085 is genuinely an nc=1 LOOKUP transparent first frame — A=0 everywhere; the visible frames are 2087–2113); the raw pool dumps decode as warm RGBA5551 sprites — mean RGB over opaque texels **(255,238,139)**, R-dominant, correct vertical-blob shape (rows 3–10 of the 16×14 tile); e.g. texnum 2111's pool word is now `0xc2f1`, which the importer reads back as `0xf1c2` = R30,G3,B1 — the true decoded value M-113 recorded pre-fix, i.e. exactly the pool state whose rendered PPMs M-113 proved correct (mean 141,127,53, clean animation). (4) **Regression safety is structural, not empirical:** RGBA32/RGB24 pool bytes are bit-identical to the M-114-revert build (`PORT_PIXEL32` = identity in both), so muzzle flash / ammo HUD / flares / crosshairs — all RGBA32 — render exactly as in the state the user last confirmed fine; no 32-bit path was touched at all. The other non-zlib 16-bit images (texnum 1198–1201 RGBA16, 2430 IA16, 2510–2523 RGB15) were equally byte-reversed before this change and are now corrected by the same importer contract; they do not load during a Dam run, so their on-screen state is owed to the next human playtest in whatever level uses them. (5) **Probes left in tree** (env-gated, inert): `GE_D219RAW` generalized in `texInflateNonZlib` — header line for every non-zlib wide-pixel decode (`format <= TEXFORMAT_IA16`), first-row pixel dump for RGBA16/RGB15/IA16, no texnum filter; plus the pre-existing D172/D219 and `GE_TEXDUMP` fire-dumper probes. **Status: RESOLVED (2026-09-12)** — user playtested this build and confirmed it works (fire correct, no muzzle-flash/ammo-HUD regression); D219 closed. | -| D220 | **1P muzzle flash position shifts upward at higher `Video.FovScale` (M-87, user QA, Jungle/M16).** Likely shares D211's noted residual: the viewmodel draws through `c_perspfovy`/unscaled fovy while the world view is FovScale-scaled (`fr.c:737`), so a flash sprite anchored to viewmodel-space vs. screen-space math can drift as the two diverge more at higher scale. | **ANALYZED (M-91) — the suspected unscaled-viewmodel root does NOT hold; this is correct perspective behavior, likely cosmetic/QoL.** The 1P hand + flash are model nodes in ONE gun DL (`gunfire.c` builds `rwmtx[1..4]` for hammer/flash/billboard nodes) drawn through the single per-frame projection from `viSetupCurrentPlayerView` — which IS FovScale-scaled on PC. So the flash and the muzzle it attaches to share projection and matrix chain: their relative position is geometrically preserved. What moves is the whole camera-anchored viewmodel: under perspective, screen offset from center ∝ 1/tan(fovy/2), so widening the FOV migrates every camera-space point (gun body included) toward screen center — a muzzle sitting slightly below/right of center visibly drifts up-left at FovScale 150. Same family as the M-85 accepted "viewmodel scales down, stays bottom-right anchored". `c_perspfovy`/`currentPlayerSetCameraScale` do stay unscaled (the D211 note) but that feeds frustum-cull/screen↔world math (→ D222), not the flash's render path. **Disposition: human call** — if it bothers at high FovScale, the fix is a QoL viewmodel re-anchor/scale-at-FOV (VIEWMODEL-RESEARCH.md family), not a fidelity bug; no game-logic change either way. Optional headless confirm: Jungle M16 fire at FovScale 100 vs 150, measure flash centroid vs muzzle in PPM pairs (expected: both shift toward center together). | -| D85 | room primary/secondary DL → `texLoadFromGdl` garbage | OPEN (safety-netted; widen/pool fixes landed, geometry now renders) | -| D86 · D87 | modelInitRwData truncated ptr · attract-demo BE `ramromfilestructure` | resolved | +| D220 | **1P muzzle flash position shifts upward at higher `Video.FovScale` (M-87, user QA, Jungle/M16).** — full `## D220` entry at file tail | **ANALYZED (M-91) — the suspected unscaled-viewmodel root does NOT hold; this is correct perspective behavior, likely cosmetic/QoL.** The 1P hand + flash are model nodes in ONE gun DL (`gunfire.c` builds `rwmtx[1..4]` for hammer/flash/billboard nodes) drawn through the single per-frame projection from `viSetupCurrentPlayerView` —… | +| D85 | **Room primary/secondary DL → `texLoadFromGdl` garbage.** — see §H (D85 entries: root cause + widen/texture-pool fixes) | OPEN (safety-netted; widen/pool fixes landed, geometry now renders) | +| D86 · D87 | **modelInitRwData truncated ptr · attract-demo BE `ramromfilestructure`.** — see §H (D86, D87) | resolved | | D88.1–D88.3 · D88.5–D88.6 | `Usetup*Z` header + sub-table width/endian conversion (`d88_emit.py`) | resolved | -| D88.4 | `propDefs` polymorphic record stream not byteswapped → `setupDoor` crash | resolved (`d88_propdefs.py`); layout audit M-20 → **D132** | +| D88.4 | **`propDefs` polymorphic record stream not byteswapped → `setupDoor` crash.** — see §H (D88.4) + `## D132` | resolved (`d88_propdefs.py`); layout audit M-20 → **D132** | | D132 | D88 propDefs layout audit (M-20): converter cursor confirmed vs real PC struct layout for all types the 21 levels emit.

So the *transition* works; only the scripted cutscene step is skipped or silently fails. Static trace: Dam's end sequence is `UsetupdamZ` ailist `ai_24` (id 0x1004, gated `if_bond_in_room_with_pad(0x4a01)` — Bond reaches the exit) → lock controls, `bond_set_locked_velocity` (auto-walk off edge), wait `if_bond_y_pos_less_than` (Bond falling) → fade → `if_objective_all_completed` branch → `camera_switch`/`jump_to_ai_list` into the abseil ailist `ai_17` (id 0x0412: `screen_fade_from_black`, `music_xtrack_play`, `guard_play_animation(0xb100…)` = rappel anim on a puppet chr, three `camera_switch` w/ fades, `exit_level`). `camera_switch(TAG,…)` resolves a `CutsceneRecord` (propDef type 46, records 322/324/326 paired with Tags 10/11/12) via `tagGetCommandIndex` + `setupGetPtrToCommandByIndex` (a **command-index count walk over the propDef stream** using `sizepropdef()`). CutsceneRecord itself is all-scalar 28 B, correctly converted (`d88_propdefs.py` 46→28). **Leading hypotheses, unverified:** (a) the index-count walk desyncs because some earlier propDef type Dam emits (Vehicle 321 — D122 "medium confidence" tail; TintedGlass) has a wrong PC `sizepropdef` stride → `camera_switch` gets a bogus `cdef`/`TagIndex<0` → cutscene silently skipped, `ai_17` falls through to `exit_level`; (b) the trigger chr for `ai_24`/`ai_25` isn't spawned / `if_bond_in_room_with_pad` never true and the level ends via a different path; (c) D75/anim-model family — the puppet `guard_play_animation` rappel anim doesn't render (third-person Bond model absent, like the gun-barrel/cast models) so the cutscene "plays" invisibly but the user perceives it as skipped (less likely — user reports an instant cut, not a blank pause). | DIAGNOSTIC SHIPPED, not root-caused (`c95713f5`, `#ifdef PORT` + `GE_D160=1`): trace points in `bossReturnTitleStage` (entry + caller), `bondviewSetCameraMode` (mode/stage/`g_IntroSwirl`/intro-anim-idx/caller), and AI cmds `EndLevel`/`exit_level`, `CameraLookAtBondFromPad`, `CameraSwitch` (prints `cdef` ptr / `TagIndex<0` / tag `NOT FOUND`). **Next step:** user plays Dam to the exit with `GE_D160=1` (via `debug.ps1`); the trace answers (1) does `CameraSwitch`/`CameraLookAtBondFromPad` execute at all → trigger fires? (2) if yes, is `cdef` a sane pointer → propDef-walk / converter bug (a), same family as D122/D132/D157; (3) if the cam cmds never run → ai_24 trigger / chr-spawn bug (b). If it's (c), `bondviewSetCameraMode` shows POSEND being set + control returns normally. This is likely a WRITE-UP-then-fix (propDef stride) rather than a hack. Confidence in hypothesis (a): medium. **M-106 static re-audit (no build/runtime access this session — see note below): hypothesis (a) independently RE-CONFIRMED RULED OUT.** `CutsceneRecord` (`src/bondtypes.h:3785-3792`, propDef type 46) is **all-scalar** — `PropDefHeaderRecord` (4B header) + `coord3d pos` (12B, 3×f32) + `theta`/`verta`/`pad` (4B each) = 28B exactly, zero pointer/union fields, so it cannot exhibit the D122/D126/D132/D209 pointer-width-growth pattern at all (nothing to widen); this matches `porting-notes.md`'s already-recorded M-31 conclusion (`§ "D160 — a propDef command-index walk desync..."`) that the stride cross-check is clean for all 48 types. Traced the `AI_CameraSwitch` path end-to-end (`chrai.c:3990-4013`): `tagGetCommandIndex`/`setupGetPtrToCommandByIndex` resolve `cdef`, then `gBondViewCutscene = cdef` and `bondviewSetCameraMode(CAMERAMODE_POSEND)`; the render side (`bondview2.c:1558-1590`) reads `gBondViewCutscene->pad`/`pos`/`theta`/`verta` directly off that pointer with no intermediate copy/struct-punning step that could introduce a *new* aliasing bug — this leg of the pipeline is clean. **Did not get far on hypotheses (b)/(c)** (AI trigger-fire vs invisible-puppet-render) — no interactive session / no build toolchain available in this worktree (`gcc`/`cmake` not on `PATH`; MSYS2 MINGW64 environment not active), so the `GE_D160=1` Dam-to-exit playthrough this row has needed since M-31 still has not been driven. **Confidence update: hypothesis (a) — HIGH (ruled out, independently re-derived, not just cited); (b)/(c) — unchanged, still need the live trace.** No code changes made (nothing to fix once (a) is ruled out); this is a documentation-only confirmation pass. See also D173 below — if the Cradle "Bond floating/spinning" symptom filed under this label is the puppet-render family (D75/D156), closing D173 first may explain the residual `#4 GOTO` here too. **M-107 — the live trace finally happened; (b)/(c) both REFUTED, real root cause moved to D243.** `GE_D160=1` on `-level_33` (Dam) plus a fresh-save normal playthrough all show the AI trigger firing and all three `camera_switch` commands executing (`bondviewSetCameraMode(7)` × 2-3, then `bossReturnTitleStage`) — the cutscene is NOT skipped and the puppet is NOT invisible; it renders, but corrupted (violent camera-shake artifact during each angle cut).

GE draws the Depot roof with the TLUT **disabled** (`gsDPSetTextureLUT(G_TT_NONE)` — a legit N64 idiom: a CI-siz tile with no LUT feeds the raw 8-bit TMEM texel straight into the colour pipe, i.e. it behaves as a plain **I8** texture). fast3d's `import_texture()` ignored `palette_fmt` and always did the palette lookup for `fmt==CI`, indexing a **stale `rdp.palette`** left over from a previous texture → the 16×16 image came out as pure blue/cyan/magenta noise; the "radial rays" were that high-frequency noise aliasing on the steeply-receding ceiling plane (which is also why filtering couldn't help — the data was garbage). Fix: in `import_texture()`, `fmt_eff = (fmt==G_IM_FMT_CI && rdp.palette_fmt==G_TT_NONE) ? G_IM_FMT_I : fmt`, and dispatch on `fmt_eff` (CI4→I4, CI8→I8).

Scope: front-end menu input in `src/game/front.c` (or wherever N64 stick reads are gated by the active `controldef`) — likely wants a port-layer input remap for these menu contexts specifically, not a general control-scheme change. **M-141: root cause found + fixed, port-only.** `front.c`'s menu-nav code reads `joyGetStickX/Y` — the same emulated N64 "Control Stick" channel (`stick_x`/`stick_y`) that in-level gameplay uses. `port/src/input.c`'s gamepad poll routes that channel to the LEFT physical stick by default, but `naturalPitchMode` (D194/D238's SOLITARE-style scheme, **default-on**) reroutes it to the RIGHT stick for continuous look — and since menus share the channel, they silently inherited that reroute too. The poll already computed an unused `padMenuMode` flag (`current_menu != GE_MENU_RUN_STAGE/GE_MENU_INVALID`, previously only gating shoulder-button weapon-cycle edges); moved it earlier and added a `padMenuMode` branch that always sources `stick_x`/`stick_y` from the left stick outside a running stage, regardless of `naturalPitchMode` — matching the F10 overlay's existing left-stick convention (`optionsoverlay.c`). Zero effect on in-level control feel (the branch is inert whenever `current_menu == GE_MENU_RUN_STAGE`). Verified: build green; `-level_09`/`-level_20` unregressed (1100+ frames each, no crash) — bare `-level_XX` launches skip the front end entirely, so this only proves the gameplay path (unaffected) stays clean. **In-menu feel not interactively verified this session** (no physical gamepad available in this environment) — needs a human playtest with a controller to confirm the menu now navigates on the left stick as expected. | FIXED (`port/src/input.c`, `#ifdef` not needed — port-layer-only file), feel unconfirmed. | -| D283 | **Steam Deck first-run preset (D-unnumbered in `port/src/video.c`/`main.c`, `videoApplySteamOSDefaults()`) did not apply for a user who added the game via Steam in Desktop Mode and switched to Game Mode afterward — resolution stayed at some non-native value instead of the Deck's native 1280×800 (v0.2.1 user testing, 2026-09-15).** Root mechanism, confirmed by code inspection: the preset only applies when `getenv("STEAMOS")` is truthy AND no `ge007.ini` exists yet (`main.c:126-129`, before `configLoad()`); once any ini exists, it always wins over the preset on every future launch (by design, so user F10 changes persist). **Leading hypothesis (not verified on real hardware in this environment):** SteamOS's Desktop Mode (a normal Plasma/X11 session) likely does not export the same `STEAMOS` env var that the Game Mode/gamescope session does, so a Desktop Mode test-launch (a natural step when adding a non-Steam game via its file browser) creates `ge007.ini` with ordinary Linux defaults *before* the user ever reaches Game Mode — permanently skipping the preset for that install, since the ini already exists on the first real Game Mode launch. This exact caveat was already known internally (`docs/HANDOFF.md`: "a Deck that already has an ini needs `-fresh` or F10 to pick the preset up") but was never surfaced in user-facing docs (README/release notes) — same class of gap as the stale D230 release-notes reference. **Workaround (lighter than `-fresh`, which also wipes the save):** F10 → Resolution → 1280×800 manually; takes seconds, no data lost. | OPEN — mechanism understood, root cause (Desktop-vs-Game-Mode `STEAMOS` env var difference) unverified on real hardware; user-facing workaround documented in README/release notes. | -| D280 | **D236 wall, ninth pass — fog math VERIFIED N64-faithful (±2 truncation over all 2505 verts of `0xc81049d8`; D276 owed step #1 closed), the IA8 noise class VISUALLY confirmed as the weave's painter (`GE_D278C` collapse: band HF 14.8→2.9, no trees appear without it — first unconfounded test), full census at both confirmed weave points (only 3 real classes; two log entries are probe artifacts), D276's depth-race read INVERTED (`0x0c184b50` tree cards are in FRONT of the noise quad, z/w smaller=closer), `0xc8102078` ruled out as trees (terrain, 1.4M tris), and `0x0c184b50` shown to barely instantiate under deterministic `-level_36` boot (~4 tris vs 720 free-run) with CPU-baked bimodal fog 25/255. **No quick win for trees** — remaining work is CPU-side instantiation/room-streaming, not a port fix. | REFRAMED again — no fix; next steps in detail section, see D236 | -| D275 | **D236 wall, eighth pass — probe upgrades:** `GE_D270PIX` extended from a single point to a semicolon-separated list (each line now tagged `pix=(x,y)` + D274's reliable `addr=`); `GE_D270KEEPOML` gained a "kept N tris" counter so a black A/B capture is diagnosable (tick-misaligned vs. a genuine render-interaction bug).

Confirmed mips are generated (`genmip=1`) and enabled (`tex_lod=1`) for that texture, with correct `GL_REPEAT` wrap — ruling out "mips absent" as the mechanism.

Both are confirmed CI8 (fmt=2 siz=1, matches D269). Findings: (1) per-instance UV is **not identical** across cards sharing the same bound texture (`seq`) — small (~0.3 texel) jitter for the OPA class, larger (~1.6 texel) jitter for the XLU class — consistent with genuinely distinct authored per-vertex S/T, not a converter collapse; D265's "identical u:0..64/v:0..16" observation traces to a different (non-wall) draw class caught by the old unfiltered band gate, not these cards. (2) The XLU class's U range spans **~143–145 texels — ~4.5× the tile's 32-texel wrap period** (`mask=5,5`); the OPA class stays within roughly one tile width. (3) Read `tools_pc/d43_emit.py`'s vertex emit path (`emit_main_vtx`): `tc[0]/tc[1]` (offsets 8/10 of the 16-byte `Vtx`) go through a plain `be16` byteswap with no scale/offset — **no converter bug possible here**; the ROM must already encode this ~4.5× wrap. Reframes the leading hypothesis: this heavy horizontal wrap is by design (Rare tiling one texture across a long tree-line quad), so the "wall" comes from *how* the port renders that wrap, not from wrong UV data — TEXTLOD/mip generation and GL wrap-boundary sampling for a highly-minified, wide-wrapped CI8 tile is now the top suspect again (D269 hypothesis #2), ahead of fog/palette. | OPEN — probe `GE_D272` added to `port/fast3d/gfx_pc.cpp` (env-gated, uncommitted); wall still open, see D236 | -| D137 | right-mouse (aim-sight) crash: `gunDrawSight` (`gunfire.c:6235`) `s32 sp54` holds a `Gfx*` the whole function (`sp54 = *gdl`; `texSelect(&sp54,…)`/`display_image_at_position(&sp54,…)` take `Gfx**`).

On little-endian PC the low byte is `extrascale`, so `(u8)obj[0]` is never `PROPDEF_END` → the `while` runs off the end of the blob, and the `switch` dispatches on garbage → `objFreePermanently()` on records that aren't `ObjectRecord`s → `obj->prop`/`obj->model` read adjacent float data (`0x3e567400405c30c0`) → AV in `objFreeEmbedmentOrProjectile` (`propobj.c:888`). `sizepropdef()` and every other propDef consumer already use `pdef->type` (struct member, offset 3) — only this one spot used the raw byte cast.

On N64 those ids always resolve so the decomp never guards. Twist: `str.c`'s `strcpy/strncpy/strcat` are `__nonnull__` **builtins** to GCC, so a plain `if (src == NULL)` on the parameter is optimised away as provably-dead (verified: `-Og` elided it, no `test` in the disassembly). Fix: `#ifdef PORT` NULL guards that launder the pointer through an empty `__asm__` (`GE_IS_NULL()` / `ge_launder_ptr()`) so the check survives — NULL src → treat as empty string (blank text, not a crash), NULL dst → return.

Watch-page repro is interactive — user to re-verify. porting-notes.md §C. | -| D152 | **Mission-failed / objective-failed → permanent black screen (M-28, user bug report — LIVE process inspected, not yet fixed).** User killed Trevelyan in Facility (Ctrl = fire, no crouch bind) → failed the objective → screen faded to black and never came back; process stayed alive under `debug.ps1`. `gdb.txt` (kept running): rendering stops dead at frame 12600 (`frames=12657` frozen across 206 heartbeat dumps / ~7 real min), VI pacemaker still posts. **Deadlock on `s_imLock`** — the D147 recursive-mutex that backs `osSetIntMask`. Both consumer threads are blocked in `pthread_mutex_lock(&s_imLock)` and neither owns it: `mainThread` = `sndSetScalerApplyVolumeAllSfxSlot` → `sndApplyVolumeAllSfxSlot` → `sndSetSfxSlotVolume` → `alEvtqPostEvent` (`event.c:82`) → `osSetIntMask(OS_IM_NONE)` (`libultra.c:1232`); `amMain`/audioThread = `amHandleFrameMessage` → `alAudioFrame` → `sndPlayerVoiceHandler` → `alEvtqNextEvent` (`event.c:47`) → `osSetIntMask(OS_IM_NONE)`. `sndSetScalerApplyVolumeAllSfxSlot` is the **mission-failed audio fade-out** (ramps `g_sndSfxVolumeScale` → 0 each frame, `AL_SNDP_RELEASE_EVT` posted per active `ALSoundState` per frame) — so the fade-to-black *is* the intended fail transition, and it hammers the event queue hard enough that the `osSetIntMask` lock is left owned by a party not in the 3-thread dump (a leaked unbalanced `OS_IM_NONE` — libaudio has early-return mask paths — or a transient thread that acquired it and exited; `gdb.txt` shows `New Thread`/`exited` churn every few k frames). D147's "the decomp never blocks while holding OS_IM_NONE → cannot deadlock" assumption is **falsified** by this path. Same family as D147 / porting-notes.md §D4. | MITIGATED (`port/src/libultra.c`, M-28, `#ifdef PORT`/port-only). `osSetIntMask` is now a **self-healing** logical lock: `OS_IM_NONE`/`OS_IM_ALL` acquire/release a process-wide recursive critical section tracked by `s_imHeld`/`s_imOwner`/`s_imDepth` under a short bookkeeping mutex `s_imMx` + condvar. Normal (balanced, microsecond) audio critical sections behave exactly as the D147 recursive mutex did. A waiter that blocks **> 2 s** (`OS_IM_STUCK_NS`) concludes the holder leaked it, logs `LOG_ERROR` with the stale `s_imOwner` + the stealing caller's return address, and **steals** the section — so a leaked/unbalanced `OS_IM_NONE` (or an acquire-and-exit transient thread) can no longer wedge the game forever; worst case is a ~2 s audio hiccup + a log line naming the leak. Builds clean. Still OPEN: the exact leaking call site (find it from the `D152: ... stealing from owner=` log next time it fires) and the proper narrow fix (dedicated `ALEventQueue` lock, or restore-on-thread-exit). Regression check deferred — `-level_09`/`-level_20` both flaky under the current machine load (D117/D134), and clean `master` itself has a separate nondeterministic `-level_09` frame ~900-1400 `0xc0000005` (see below). | -| D152+ | **D152 addendum — static audit + narrow fix (M-31).** Audited every `osSetIntMask(OS_IM_NONE)` in the *compiled* audio code (`event.c` `alEvtqNextEvent`/`alEvtqPostEvent`/`alEvtqFlush`/`alEvtqFlushType`, `csplayer.c` `__CSPRepostEvent`, `synaddplayer.c` `alSynAddPlayer`, `snd.c` `sndRemoveEvents`/`sndSetupSound`/`sndDeactivateAllSfxByFlag`): **all balanced on every path** — `alEvtqPostEvent`'s lone early `return` (`event.c:86`, freeList empty) restores the mask first. The §F D152 guess "libaudio has unbalanced early-return mask paths" is **not** borne out. Two real defects found + fixed `#ifdef PORT` (N64 verbatim `#else`): **(1)** `sndSetSfxSlotVolume` (`snd.c`) walks the live `ALSoundState` list and posts `AL_SNDP_RELEASE_EVT` to the shared `ALEventQueue` **without holding `OS_IM_NONE`** — unlike its structural twin `sndDeactivateAllSfxByFlag`, which wraps its identical walk. On PC that's an unguarded walk racing `amMain` *and* one lock acquire/release per matching sound; the mission-failed fade (`sndSetScalerApplyVolumeAllSfxSlot`→`sndApplyVolumeAllSfxSlot`→ this, every frame, every active sound) turns it into a per-frame lock-acquire storm on `mainThread` = exactly the §F dump's "hammers the event queue hard enough that the lock is left owned." Fix: hold `OS_IM_NONE` once across the whole walk (nested `alEvtqPostEvent` hits the recursive depth++ fast path, no new contention window); also wrap `sndApplyVolumeAllSfxSlot`'s slot loop so the whole volume update is one recursive hold (1 real acquire/frame instead of `SFX_SLOT_COUNT × active-sounds`). **(2)** The actual leak matches the §F dump's *other* hypothesis — "a transient thread acquired `OS_IM_NONE` and exited" (`gdb.txt` shows `New Thread`/`exited` churn). `port/src/libultra.c` `portThreadWrapper` now calls new `imThreadExitRelease()` after the thread entry returns: if that thread still owns `s_imHeld`, release the orphan immediately (+ `LOG_ERROR` naming it). This removes the wedge *and* the ~2 s steal hitch, and stops the **re-wedge** that occurs when a new host thread reuses the dead thread's pthread id and `imAcquire` mis-detects recursion (`s_imOwner == self`). The M-28 steal-lock stays as the last-resort backstop for a genuinely unbalanced *same-thread* path (none found, but cheap insurance). Build green (240/240); `-level_09` frame 300 renders 91.7% non-clear, crash-free; `-level_20` boots crash-free (frame-count flaky under load per D117/D134, no `D152:` log).

Symbolicated `mainThread` stack from the port's own hang dump: `modelConstrainOrWrapAnimFrame` ← `modelTickAnim` ← `chrUpdateAnim` ← `chrTick` ← `playerTick` ← `propsTick` ← `lvlRender`, sampled there across *every* heartbeat dump. Root cause: `waitForNextFrame()` (`src/game/frametiming.c`) sets `nextFrameTime = (osGetCount() − prev + 387937) / 775875` and passes it **unclamped** to `updateFrameCounters` as `deltaFrames`. `osGetCount()` is wall-clock on the port (D117), not VI-locked, so a real-time stall — the asset load at the cutscene→debrief boundary, made far worse by the user running a local LLM on the same box — makes `nextFrameTime` balloon to hundreds/thousands. That becomes `speedgraphframes` → `g_ClockTimer`, which drives `modelTickAnim(model, g_ClockTimer, 1)`'s `while (numticks-- > 0)` loop once per character per render, plus dozens of `for (i = 0; i < g_ClockTimer; i++)` sim loops (`bondhead.c`, `bondview2.c`, `explosion.c`, `options.c`…). One render then does thousands of anim ticks × N characters → multi-second frame → heartbeat trips, and the slow frame feeds an even bigger delta next time → unrecoverable spiral.

Same false-positive class the docs warn about every session (M-13..M-22, M-25 Silo ~frame 300 freeze). The crash PC was in a system DLL (a `memcpy` off a buffer) and the frame varied run-to-run — both consistent with the port's host-scheduling jitter under load (`osGetCount` is wall-clock, variable-timestep sim), not a deterministic defect. `romdataFixupMusicSeqTable: seqCount 63 exceeds blob capacity 1` is an EXPECTED benign warning on the header-only first `romdataFixupMusicSeqTable` call (music.c:736; the full-size second call at :742 is silent) — not related. **Lesson: don't regression-test while builds/other runs are in flight.** | NOT A BUG — closed. Run anchors on a quiet machine. | -| D151 | **Watch data all blank — objectives / mission background / M / Q / Moneypenny (M-28, user bug report).** Not a crash (D150 fixed that); every line renders empty. The watch text lives in `propDefs` record types **35** (`WatchMenuObjectiveText`) and **23** (`ObjectiveStart`). In the setup stream each record's 3rd word is a **plain 32-bit language slot id** (see `assets/obseg/setup/Usetup*Z.c` `propDefs[]`: `_mkword(0,_mkshort(0,35)), menu, 11281, 0`). The decomp structs `struct watchMenuObjectiveText` / `struct objective_entry` decode that word as `u16 reserved; u16 text;` and read `text` at offset `0xA` — which only works on the N64 because the id sits in the **low 16 bits of a big-endian word**. On LE, `tools_pc/d88_propdefs.py` `_bswap32`'s the whole word (correct for a 32-bit field), moving the id to the low bytes, so `text` (u16 @0xA) reads `0x0000` → `langGet(0)` → NULL → `get_ptr_text_for_watch_breifing_page` / `get_text_for_objective` return NULL/blank. This is the "briefing/objective text renders blank" side-effect left open under D143 / D150. The per-level lang bank itself IS loaded in-level (`langLoadToAddr(langGetLangBankIndexFromStagenum(stageId))`, `prop.c:1274`). | FIXED (`src/bondtypes.h`, `#ifdef PORT` — `text` is a full `u32` covering the whole word in both structs; N64 `u16 reserved; u16 text;` kept under `#else`).

Root cause: `romdataFixupFont` (`port/src/romdata.c`) converts the N64 24B fontchar array to the PC 32B array **in place**, forward-field, backward-glyph. PC−N64 stride = 8, so for glyphs 0/1/2 `d` overlaps `s` by less than the 24B read span and an early field write clobbers a later field's source mid-`for k<5` loop → glyph 1's `width` = `bswap(index)` = `0x01000000`, glyph 2's `pixeldata` = `pcPixOff+(index−pixStart)` ≈ `0x020002e8` → `+= font_base` → wild → fast3d AV. On N64 the array is read-only rodata, never re-laid-out, so no bug there. NOT the model-GDL relocation (`sub_GAME_7F0762E0` / `texLoadFromGdl`) the D124-Facility addendum suspected — `gdl` there is still a segmented `0x05xxxxxx` value so the `& 0x00ffffff` masks are correct, and `texLoadFromGdl` never copies a `G_SETTIMG` for these levels. | resolved — stage all 6 N64 fields in a local `f[6]` before writing any.

This is a **linker-adjacency assumption**: on N64 `.data` the two file-scope globals are emitted in source order so `&legalscreen_MRD == legalpage_text_array + 12` and the loop count is exactly the array length. mingw/GCC reorders them — in `build-pc/ge007.x86_64.exe` `legalscreen_MRD` links at `0x1401305e0`, **0x60 bytes before** `legalpage_text_array` at `0x140130640` (verified via `nm`). So `legal_text_end < legal_text_ptr` from the start; the `do/while` runs the body **once** (entry 0, "TWYCROSS BOARD OF GAME CLASSIFICATION" — long + CENTER_ALIGN so it wraps to ~2 visual lines = the "classification line + one below" the user saw), then exits. The other 11 legal lines never render. NOT a D68 image-table bug — the legal screen references **zero** `sImageTableEntry`s; it is pure `langGet()` font text via `display_aligned_white_text_to_screen`→`textRender`, plus the 3D `logoinst` model (`subdraw`, absent — D75 family, parked).

Root-caused with `GE_DTEX`: the photo is a **65×65 I4** (also seen: 65×65 I8, 95×32 IA8) with a full mip chain; `import_texture_i4` uploads it `line_size_bytes*2` (= padded stride) wide and `size_bytes/line` tall — geometry fine. The comb is **`texSwapAltRowBytes` (`src/game/image.c:2191`)**: it pre-swaps every **odd** texture row in 8-byte (one-`u32`) groups to compensate for the N64 RDP's odd-line TMEM address XOR (bit 2) during 4-byte-word `gDPLoadBlock` loads. fast3d does **not** emulate that XOR (no odd-row handling anywhere in `gfx_pc.cpp`), so the pre-swapped odd rows stay scrambled in the uploaded GL image. It's called on *every* level of *every* texture on *every* path (§4), but only bites where the texture is large enough and viewed 1:1 to see the 8-texel comb — glaring on the ~big front-end photos, ~invisible on small HUD glyphs / distant in-level surfaces (which is why it was written off as "front-end model" work for many sessions). Same class as the K0-fold / interrupt-mask hardware-quirk shims — belongs in `port/`, not game logic. | **FIXED** (`src/game/image.c`, `#ifdef PORT` early-`return` in `texSwapAltRowBytes` — fast3d wants a plain linear image; N64 body kept verbatim under it). Verified: wallet-Bond photo renders as a clean recognisable grayscale portrait (still 180°-rotated — D75 model-transform family, parked); `-level_09` frame 200 coverage 91.62 vs 91.66 golden (D117 noise) and a visual frame is clean (tiled floor / monitors / world-map screen all correct). Confidence: **high** (GE_DTEX + before/after screenshots). The residual over-tall-mip (RC2) and non-PoT wrap (RC3) issues are separate and still parked; this only removes the row-swap. porting-notes.md §C. | +| D159 | **Front-end wallet-Bond photo (and other large front-end I4/I8/IA8 textures) render "interlaced" / combed (M-31, user bug RC1 / D149).** — full `## D159` entry at file tail | **FIXED** (`src/game/image.c`, `#ifdef PORT` early-`return` in `texSwapAltRowBytes` —… | -| D165 | **Front-end menu cursor doesn't feel like a mouse pointer (M-31, user bug B5 follow-up).** M-30 added a "menu pointer mode" that fed mouse *velocity* into the stick axes, but `front.c frontUpdateControlStickPosition` *integrates* the stick as a velocity into a screen-pixel cursor position (`cursor_h_pos += (stickx*0.075 ± 0.5) * g_GlobalTimerDelta`, ±5 deadzone, ±70 clamp, cursor clamped into the ~320×240 virtual rect − 20px margin). Velocity-in → velocity² cursor. **Fix (port-only, no `front.c` edit):** `input.c` now runs a P-controller — it keeps its own estimate `menuEst{H,V}` of where the game cursor is, integrated each poll with the *exact same recurrence* as `frontUpdateControlStickPosition` (`menuCursorStep()`), accumulates a `menuTgt{H,V}` target from raw mouse motion (clamped to the same rect), and emits `stick = clamp(MENU_P_GAIN·(target−est), ±70)`. `MENU_P_GAIN = 6.0` → per-poll error decay ≈ 0.45 (`0.075·6`), so no overshoot and ~8-poll settle; stick falls under the game's ±5 deadzone within ~1px of target so the cursor parks with zero jitter/drift. The estimate re-syncs to the true cursor whenever the target is held at a screen edge (both clamp). `Input.MenuPointerSpeed` scales the mouse→target mapping (bump toward 150–200 if the sweep feels short — `est` steps once per controller poll ≈ 2×/rendered-frame vs `front.c`'s 1×/frame, a rate mismatch absorbed by this knob). `Input.MenuPointerMode` (0 = old velocity, 1 = pointer, **default 1**) is the escape hatch. `GE_INPUTLOG` prints an `menuptr est=/tgt=/eff=/stick=` trace line for tuning. With no mouse motion `target==est==centre` → `eff=0` → emitted stick unchanged → prior behaviour exactly. | FIXED (`port/src/input.c`; `Input.MenuPointerMode`, `Input.HipfirePitchSpeed` added). Build green, `-level_09` + `GE_STARTMENU=6` smoke crash-free. Feel-check owed (headless can't exercise the mouse). | -| D166 | **Hipfire mouse pitch is digital while yaw is analog — inconsistent feel (user bug B7 / D118a, "cheaper alternative").** In hipfire GE takes yaw from the analog stick-X but pitch only from digital C-up/C-down, so `input.c` emitted one C-button per poll once `|mouseΔY|` crossed a fixed threshold — an on/off step. **Fix (port-only):** emit the C-button as a *duty-cycled pulse* whose firing frequency scales with mouse-Y speed — `duty = |dyLook|·(HipfirePitchSpeed/100)/HIP_PITCH_FULL` (clamped ≤1), phase-accumulate, fire when the phase wraps. Fast mouse → `duty≈1` → C-button every poll (solid hold, as before); slow mouse → sparse taps proportional to speed. `HIP_PITCH_FULL = 6.0` px/poll for a solid hold; `Input.HipfirePitchSpeed` (10–500, default 100) tunes it. Aim-mode (RMB, already fully analog) untouched. No mouse motion → no pulse → prior behaviour. | FIXED (`port/src/input.c`). SMALL-FIXES B7. **M-87: likely SUPERSEDABLE — see the "SOLITAIRE natural-pitch" note below.** This pulse hack was necessary because the port forces a control scheme (HONEY, the 1.1 default) whose hipfire pitch is digital-only. GE's own **SOLITAIRE (1.2) / GOODNIGHT (1.4)** schemes don't have that constraint at all (see D194) — under those, the *entire* primary analog stick is free for continuous, unclamped pitch+yaw ("natural pitch/turn"), because movement is redirected onto digital C-buttons instead. If the port switches its forced `controldef` to SOLITAIRE/GOODNIGHT (also the right move for D223's wheel-cycling design and D194's mouse-feel ask), this whole digital-pulse emulation becomes unnecessary — mouse-Y would drive the stick's Y axis directly and continuously, same as X already does, with **zero digital-button emulation for pitch at all**. Don't remove D166's code without first confirming the scheme switch; keep as a fallback for whichever legacy path still needs it. | -| D233 | **All levels (intermittent): indoor level geometry invisible near doors — you can see through walls/floors into rooms you can't see into, while world objects (terminals, furniture) in the room still draw (M-106, user QA report; screenshots `docs/img/bugs/20260912-cullingbug-bugged.png` vs `-notbugged.png`).** The geometry-vs-object split localises it to room/portal background visibility or frustum culling in fast3d, not textures/models.

Prime suspect: the texture pool / CI-cache (D217/D228 neighbourhood) not being fully reset between a level teardown and its reload — a stale arena base, a leftover palette-cache entry keyed by an address that gets reused with different content, or a texpool index not rewound — surfacing as "wrong texture" only after the reload path runs, never on a fresh level boot. Logged in `GRAPHICS-BACKLOG.md`. | OPEN — needs: does it repro on a *fresh* level boot (rules out reload-state) vs only after death/restart (confirms it); which surfaces; a screenshot. **M-108 static-analysis pass: the leading "stale CI-cache not reset on restart" hypothesis is likely REFUTED, don't re-propose it as-is.** The theory was that `g_TexCacheItems`/`g_TexCacheCount` (`src/game/image.c:38-40`, cleared only in `set_mt_tex_alloc()`, `src/game/initmttex.c:8`) survives a death/restart because the restart path skips `set_mt_tex_alloc`. But tracing the actual call graph: `set_mt_tex_alloc()` runs inside `lvlStageLoad()` (`src/game/lv.c:369`), which has exactly **one** call site (`src/boss.c:485`) inside `bossMainloop`'s outer `while (!done)` loop; that loop re-runs on *every* stage transition, driven by `g_StageNum = g_MainStageNum` (`boss.c:693`) which is set by `bossSetLoadedStage()` (`boss.c:722`) — the same function the front-end's level-select/continue path calls (`front.c:6947`). Nothing in this call graph is level-select-specific vs. restart-specific; both look like they go through the identical full reload (including the `set_mt_tex_alloc` cache reset). Have not yet found the actual death/restart trigger's call site to be 100% certain it doesn't have its own bypass, so this isn't fully closed out — but the single-reload-path structure makes the "cache survives restart" mechanism unlikely as stated. Next: find the actual death-handler call site (search for where a life/continue/retry decision is made, likely `chr.c`/a game-state machine, not yet located) and confirm whether it calls `bossSetLoadedStage`/goes through `bossMainloop`'s reload path same as normal transitions, or has a distinct lighter-weight path — if it's the same path, the real D235 mechanism is still unknown and this CI-cache theory should be dropped. | -| D236 | **Surface 1: 2D billboard trees render as a wall/sheet of tree texture instead of discrete camera-facing tree sprites (M-106, user QA report).** Eight passes so far (D265, D266–D270, D271, D272, D273, D274, D275–D276).

Since D209 and D204 both merged before this report, the SFX-cadence complaint is either (a) a genuinely distinct, audio-specific residual downstream of those fixes — e.g. a mismatch between the sim-tick-gated *trigger* (above) and the software mixer's own playback clock (`port/src/audio.c:93,155,221-222` — the synth produces samples at a measured ~21600/s against the 22050 Hz output device, the same gap D204 had to compensate for elsewhere) that specifically desyncs how *often* a shot's sample starts rather than the absolute wall-clock rate D204 measured, or (b) a stale pre-D209/pre-D204 build report. Per-weapon rate constants (`AutomaticFiringRate`/`SingleFiringRate`/`SoundTriggerRate`, `src/game/gun.h:60-82`, values in `assets/obseg/gun/*/gunWeaponStat.inc.c`) are plain compiled C literals, not ROM-serialized data, so no pointer-width/ABI reconciliation issue applies here. | **OPEN — not root-caused; static call-site tracing only, no runtime verification possible in this environment.** Confidence LOW-MEDIUM that this is a *new* bug distinct from the D155/D186/D193/D204/D209 timing-keystone family (all of which gate the identical `deltaFrames→speedgraphframes→g_ClockTimer→g_GlobalTimer` chain this SFX trigger consumes). Raise confidence by: (1) confirming the user's build/commit postdates the D209 merge; (2) a `GE_AUDIOTRACE`-style capture logging the tick (`g_GlobalTimer`) and/or wall-clock timestamp of consecutive same-weapon fire-SFX requests during sustained auto-fire (AK47/Klobb, `AutomaticFiringRate=0x03`), diffed against the weapon's rate constant and against N64 reference footage's frame-count between shots. | -| D241 | **Player gunshot SFX goes silent under some conditions — reported on Bunker with the alarm sounding, "or some other factor" — but only for PP7 and AK47, Klobb unaffected (M-106, user QA report, concrete repro).** This is very likely **D207 finally reproduced.** D207 (M-77) root-caused that GE's SFX player has a hard **8-voice cap** (`MUSIC_SFX_SEQ_MAYBE_MAX_SOUNDS`, `src/music.c:76`) and that D206's fix made the alarm klaxon (`ALARM3_SFX`=163, triggered from `handle_alarm_gas_timer_calldamage()`, `src/game/propobj.c:14457`) a genuine **infinite ADPCM loop** that now legitimately occupies one of those 8 voices for the alarm's whole duration; the manual preemption scan (`snd.c:~347-392`) refuses to steal any *owned* LOOPED voice (the M-65 carve-out only exempts *ownerless* loops), so once 8/8 voices are held, a new one-shot request is silently dropped via `sndDisposeSound` (`snd.c:391`). D207's own M-77b session built a `GE_FORCEALARM=1` BUNKER1 harness and could **not** reproduce audible drops (`[D207-DROP]=0`), and explicitly left as "owed": *"needs a real repro from the user: which level, which weapon/situation."* This report supplies exactly that (Bunker, alarm). **Investigated why PP7/AK47 and not Klobb, inconclusive at the code level:** Klobb (`ITEM_SKORPION` — confirmed GE's internal name for the Klobb via `src/game/player.c:576`, `skorpion_stats` in `assets/obseg/gun/skorpion/gunWeaponStat.inc.c`) and AK47 (`ak47_stats`, `assets/obseg/gun/ak47/gunWeaponStat.inc.c`) share the **same** `AutomaticFiringRate=0x03` (fast auto), while PP7 (`wppk_stats`, `assets/obseg/gun/wppk/gunWeaponStat.inc.c`) is semi-auto only (`AutomaticFiringRate=0xFF`) — so a naive "fires faster ⇒ more self-inflicted voice contention" theory does not cleanly explain grouping PP7 with AK47 against Klobb. All three weapons' fire SFX (`GUN_B1_MGUN3_3_SFX`=Klobb, `GUN_B2_HEAVY_SFX`=PP7, `GUN_B4_BOLTACTION_SFX`=AK47 — `src/bondconstants.h:2277-2280`) go through the identical one-shot, priority-0x40 `sndPlaySfx` path (`gunfire.c:3246-3286`); no per-weapon distinction exists in the trigger or priority *code*. A real distinction, if one exists, most likely lives in the **sample bank data itself** (per-sample envelope/decay length — a longer-tailed sample stays `PLAYING` and stealable/held longer, changing its odds in the preemption scan) — that data is ROM-derived binary content, not inspectable without the extracted ROM (`./data/`, absent in this worktree). Confirmed the voice-allocation/preemption code is unmodified `src/snd.c` game logic, not a `port/` mixer bug: `port/src/mixer.c`/`port/src/audio.c` implement DSP synthesis and device output only (per D199), with no SDL `Mix_*`-style channel-priority layer in the port to have introduced a new bug. Per AGENTS.md non-negotiable #2, any real fix belongs in D207's already-designed (reverted, M-77b) last-resort LOOPED-preemption pass in `snd.c`, not in `port/`. | **OPEN — not newly root-caused; high confidence this is D207 reproduced, not an independent bug.** Recommend folding this repro into D207 (or closing D241 as a duplicate once D207 is reopened) rather than tracking separately. Next: re-run M-77's `GE_FORCEALARM=1` harness on `-level_09` with scripted PP7 and AK47 fire (not just generic fire) against Klobb as a control, watching `g_sndAllocatedVoicesCount` / the (currently reverted) `[D207-DROP]` counters to see whether the 8-cap is actually hit for two of the three weapons and not the third — or whether it is really the sample-envelope-length distinction above. No runtime verification possible in this environment (no ROM/display). | -| D242 | **Player-death sequence UX regression vs N64 original: PC requires an LMB click to proceed to the mission-failed/file-select screen; user recalls N64 auto-plays 3 death-camera angles then transitions with no input needed (M-106, user QA report).** **The 3-angle auto-replay and its no-input auto-transition both exist, unmodified, in the decomp — confirmed, not a design difference removed for the port.** `bondviewSetCameraMode(CAMERAMODE_DEATH_CAM_SP)` (`src/game/bondview2.c:901-1010`) calls `pickDeathCameraAngles()` (`bondview2.c:641-782`, picks a fresh random valid camera angle each call) to stage each replay; when it returns 0 — no further valid angle found — the code calls `bossRunTitleStage()` directly, and the source comment at `bondview2.c:1006-1007` literally reads *"...or when the three death replays are finished."* The 3-cycle count is driven by `bondviewAdvanceCameraMode()` (`bondview2.c:1041-1078`): `CAMERAMODE_DEATH_CAM_SP` → `CAMERAMODE_DEATH_CAM_MP` → `camera_mode++`, looping back to `DEATH_CAM_SP` while `camera_mode < CAMERAMODE_SWIRL` (three iterations). Each individual replay's own advance is driven purely by animation/timer state (`bondview2.c:1467-1490`): the `g_CameraAfterCinema` flag that `bondviewAdvanceCameraMode()` acts on is set automatically once `modelGetAnimFrame(bodyModel) >= modelGetAnimEndFrame(bodyModel)`, or after a `camera_transition_timer >= 180.0f` tick-timeout fallback when there is no body model — **no button check in that branch; fully automatic.** **The button-press the user is hitting is a real, intentional N64 skip-ahead shortcut, not a port-added gate:** the same code block (`bondview2.c:1483-1489`) *also* fires the identical advance immediately on `(buttons & ~oldbuttons & (CONT_A | B_BUTTON | Z_TRIG | START_BUTTON))` whenever `bonddead && redbloodfinished && deathanimfinished` — i.e. on real N64 hardware, pressing A/B/Z/Start at any point during a death replay skips straight to the end, by design. **On the port, LMB (mouse fire) is mapped to `GE_CONT_G`, which is Z_TRIG** (`port/src/input.c:664-665`: `(mb & SDL_BUTTON(SDL_BUTTON_LEFT)) ... button \|= GE_CONT_G`; binding table `input.c:351`: `{"Z",GE_CONT_G}`) — exactly one of the four original skip buttons. So an LMB click during the death sequence is GE's own original cutscene-skip input, faithfully wired through the port's control remap, not a port-invented "click to continue" prompt. **What this investigation could not determine** (no build/runtime access in this worktree): whether the *automatic*, no-input path actually completes on PC in a reasonable time. `camera_transition_timer` accumulates via `g_GlobalTimerDelta` (`bondview2.c:1470,1493`), which is set from the same `g_ClockTimer`/`speedgraphframes`/`deltaFrames` chain flagged in D240 above and investigated under D155/D186/D193/D204/D209 — if any residual in that chain stalls or mis-scales specifically in this state, the auto-advance could take far longer on PC than on N64 (or effectively never complete before the player gives up and clicks), which would make an LMB click *feel* mandatory even though the ground-truth logic never requires one. | **NOT A PORT-LOGIC BUG as far as static analysis can tell.** Confidence HIGH that the LMB-click skip path is faithful original behavior (Z_TRIG-mapped, exists unmodified in `bondview2.c`), not a defect to remove. Confidence LOW (untested) on whether the no-click automatic path is actually healthy on PC. Needs a human playtest: die, then **deliberately touch no input** during the death sequence and time whether/how long until the mission-failed screen appears on its own. If it never arrives without a click, the real bug is a `g_GlobalTimerDelta`/`camera_transition_timer` stall in the D240 clock family — cross-reference D240 — not a wrongly-added input gate, so there is still no `#ifdef PORT` skip-gate to remove per AGENTS.md #2. No runtime verification possible in this environment (no ROM/display). | -| D243 | **Dam end-of-level cutscene (the abseil/bungee sequence, D148/D160's subject): the camera violently shakes/"spazzes" during each of the scripted camera-angle cuts (M-107, live `GE_D160=1` trace, two interactive `-level_33` runs + one fresh-save normal-progression run).** **First, corrects D160's own premise: the cutscene is NOT skipped on the current build.** Both debug-loaded runs show exactly the AI-script-scripted sequence firing: `bondviewSetCameraMode(7)` (`CAMERAMODE_POSEND`, the cutscene camera-lock state) called 2-3 times, matching `ai_17`'s three `camera_switch` commands in `UsetupdamZ.c`'s abseil ailist (`assets/obseg/setup/UsetupdamZ.c:2656`+), followed by `bossReturnTitleStage`. So D160's original (b)/(c) hypotheses (AI trigger never fires / puppet renders invisibly) are **refuted on this build** — the mechanism runs; what's broken is what it renders. **Root cause candidate, directly observed:** right in the camera-cut window, fast3d's D146 catch-all (`port/fast3d/gfx_pc.cpp:3037`, "unknown GBI opcode … ending DL") fired a tight burst — same 4 memory addresses repeating every frame for ~10 frames, then clean — with payload bytes `0xfafbfbfcfcfbfdfc`/`0xfcfafbfbfafbfafb`: a **freed/uninitialized-memory fill pattern**, not real GBI commands. This reads as a stale-pointer display-list read, not a decode bug — some segment/scene buffer backing the outgoing camera shot's geometry got freed or recycled while a still-in-flight display list (queued ahead in the port's double-buffered render pipeline — see D134's "pendingGfx" note, `port/src/libultra.c:733-746`, on how many frames of latency the sched round-trip can carry) still referenced it. **Independent evidence of a race, not a fixed-order bug:** the two `-level_33` debug-load runs show the camera_switch(7) calls landing in a *different order relative to* `bossReturnTitleStage` between runs (run 1: three switches, then the stage-return call; run 2: two switches, the stage-return call, *then* a third switch arriving after) — and the D146 corruption burst appeared in run 1 but not run 2 at all, non-deterministically. That pattern (symptom present/absent, call order shuffling) is the signature of a genuine timing race between the AI-list's cutscene commands and the level-exit/report-transition code, not a deterministic logic bug. **User-confirmed on real (non-debug-boot) play, not just the debug harness:** a fresh-save normal playthrough into Dam still hit the camera glitch on this same cutscene — ruling out "artifact of the `-level_33` debug boot" for this specific symptom (unlike the secondary "no report screen, straight to file-select" symptom seen only on the debug-loaded runs, which did NOT reproduce on the fresh-save run and is therefore most likely a `-level_N` debug-boot artifact per the D190 precedent, not filed as its own bug here). | **OPEN — M-109 re-analysis of the same session's raw logs corrects the timing/pattern claims above; the D134/pendingGfx race hypothesis is likely wrong.** Confidence MEDIUM on the correction, LOW-MEDIUM on the new lead. Re-reading `data/playtest_d160.log`/`_run2.log` at the `g_framesRendered` level (not just grepping for `D146`) shows the D146 burst fires **~1600-3900 frames (tens of real seconds) *after*** `bossReturnTitleStage`/the `camera_switch(7)` calls, not during them, in **both** runs — "right in the camera-cut window" and "run 1 only" are both wrong as stated above. This also weakens the D134/`pendingGfx` citation: `osSpTaskStartGo` runs `gfx_run()` synchronously and inline (`port/src/libultra.c:1232-1258`), so nothing from the cutscene's own DL submission is still in flight by the time any teardown code runs — the port doesn't have the async-RSP race the hypothesis above assumes. **New lead:** whatever screen renders in that multi-thousand-frame gap after mission-complete is the more likely site — probably `MENU_MISSION_COMPLETE` (`front.c:7267`, `constructor_menu0D_missioncomplete`) or an adjacent briefing/file-select screen in that chain, same general class as D75 (front-end model absence) / D141 (menu bad-pointer bug), not a cutscene-render race. Of the 4 repeating fault addresses, 3 read as literal zero words and only 1 matches the `0xfafbfbfc…` pattern, arguing against a deliberate poison-fill (none found anywhere in `port/`) and for either genuinely-unwritten memory or a decode landing inside unrelated valid data. Next: an env-gated `front.c` menu-transition trace (`MENU_*` id + `g_framesRendered` on every transition after `bossReturnTitleStage`) plus a `GE_PCDUMP` window over frames ~4500-8000 (not the camera-cut window) to name the exact screen/segment. Cross-ref D160 (this supersedes its stale "cutscene skipped" framing with a "cutscene renders corrupted" one, now further corrected to "corruption isn't in the cutscene render at all") and D173 (Cradle's Bond-floating/spinning cutscene bug — same subsystem family, unconfirmed shared root cause). **M-120: the `GE_D243` trace above was BUILT (statically, i.e. written) on branch `investigate/d243-cutscene-race` (`764a1f26`, pushed, not merged) — `src/game/front.c` only, `#ifdef PORT`, logs the target `MENU_*` name + a local per-tick counter on every `menu_init()` state transition. NOT build-verified: two independent sessions (the dispatched subagent, then this session re-verifying in a fresh worktree) both hit the same reproducible failure — `cmake`'s C-compiler ABI check fails with "Cannot create temporary file in C:\Windows\: Permission denied" when gcc is invoked *through* CMake/ninja, even though a bare `gcc -c` invocation from the same shell, same session, succeeds and correctly resolves its temp dir to `%TEMP%`. This is a genuine, reproducible environment issue distinct from the diff's content (static review of the diff found nothing wrong: enum cases all verified to exist in `bondconstants.h`, brace/`#ifdef` balance checked, follows the existing `GE_D160`/`GE_D178` env-gated trace idiom used elsewhere in the same file) — worth a session with a working toolchain investigating the CMake/ninja-vs-bare-gcc environment discrepancy itself as its own item, separate from D243. Next: build `investigate/d243-cutscene-race` on a session where `./build-pc.sh` actually completes, then run the `-level_33` Dam repro with `GE_D243=1` (and the existing `GE_D160`/`GE_PCDUMP` mechanisms) to correlate the trace against the D146 burst's frame range. **M-141: the M-120 toolchain blocker is EXPLAINED and worked around, GE_D243 is now build-verified.** The "Cannot create temporary file in C:\Windows\" failure isn't specific to CMake/ninja vs. bare `gcc -c` — it's this Claude Code session's `Bash` tool shell (Git-for-Windows Bash, not a real MSYS2 MINGW64 window) not exposing a usable `TMP`/`TEMP` to child processes the way an interactive MSYS2 shell does; a bare `gcc -c` from the same shell happened to not hit the temp-file path M-120 tested, which is why it looked clean while the full build wasn't. Fix: explicitly `export TMP=... TEMP=...` (Windows-style path) alongside the already-known `PATH=/c/msys64/mingw64/bin:/c/msys64/usr/bin:$PATH` fix, both before invoking `./build-pc.sh`/`ninja`/`cmake` — now also recorded in `porting-notes.md` §E as a general session-start gotcha, not just a D243-specific note. Cherry-picked the `GE_D243` trace commit (`764a1f26`) cleanly onto `release/v0.3.0` (branch `investigate/d243-fresh`), fixed one thing the original diff got wrong per this project's own D250 rule (`menu_init()` runs ~once/frame during front-end states — the diff's three `getenv("GE_D243")` calls were uncached; now a single cached `static int s_d243` check), and confirmed it builds clean. **Smoke-tested, not fully exercised:** a bare `-level_33` boot runs 1100+ frames with zero crashes and (correctly) zero `D243:` log lines — bare `-level_XX` skips the front end entirely (per this doc's own M-24-era note), so `menu_init()` never runs; this only proves the probe doesn't regress normal boot, not that it captures anything useful yet. **Still blocked on the same thing M-107/M-109/M-120 all were: an actual interactive playthrough** (main menu → Dam → abseil cutscene → mission-complete → whatever screen the D146 burst fires on, ~1600-3900 frames later) with both `GE_D243=1` and `GE_D160=1` set, which needs a human with input, not available in this session. **Possible connection to D173 worth checking in that same playthrough** (per user, M-141): D173 (floating/spinning Bond puppet in cutscenes, e.g. Cradle/Trevelyan) and D243 (stale-memory DL read some seconds after a cutscene-driven `bossReturnTitleStage`) both sit in the scripted-cutscene/level-transition neighborhood and both ultimately touch "Bond's (or a puppet's) in-world model" — no code-level link found this session (D173's own M-106 pass already ruled out the two most likely struct-aliasing sites, and D243's mechanism looks like a stale/freed buffer read in a *different* subsystem, front-end/menu memory rather than a chr/puppet transform), so treat this as an unconfirmed hypothesis to keep in mind while capturing the next live trace, not an established shared root cause. **Steam Deck playtest confirmation, same M-141 session** — user independently reported "cutscene at end of dam level is badly glitched" without prompting, matching this row's own "camera violently shakes" symptom exactly. Second independent confirmation this is real and reproducible, not a one-off; still needs the interactive `GE_D243=1`+`GE_D160=1` capture this row already calls for. | -| D245 | **IsWater water: two competing patterns with a visible seam that moves as the player looks around (mouse/aim) — "looks almost exactly like skybox" (M-116, user QA report, post-D229-fix build).** The symptom is D227's exact signature class (s16 `Vtx.tc` overflow → rasteriser interpolates between wrapped coordinates → two differently-wrong screen regions + a seam at the wrap boundary; on the sky quad the split ran on the 0–3 diagonal). Water draws through the same port path: `src/game/sky.c` water block (~905–956) — `texSelect(&skywaterimages[WaterImageId])` + `sub_GAME_7F09343C` (two-texunit cross-fade; both tiles re-declared RGBA/16b @ tmem 0, the draw D229 fixed) then a `skyRenderTri` fan over `sp274[]` under `skyPortBeginFan(sp274, s1, FALSE)` — and **the `FALSE` is a documented, deliberate tolerance of exactly this overflow**: the comment above `skyPortBeginFan` (sky.c ~1738) records that the IsWater quad is excluded from D227's tile-shift safety valve because both texunits read the same vertex tc, so a tc rescale would need matched shifts on BOTH tiles and "shifting both makes them sample identically, which flattens the cross-fade"; the 2026-09 decision was that "the water quad keeps the plain 1:1 tc and simply tolerates the overflow on its horizon vertex, exactly as it did before D227." The mechanism is real: `unk20/unk24` are S10.5 units reaching tens of thousands near the horizon; the fold rebases to a multiple of `SKY_TC_WRAP` (2048) but with k=0 an s16 tc holds only ±32767, so any wider span wraps. It was invisible before D229 because every water texel was green mottle garbage anyway; with correct blue texels the wrapped region now reads as a visibly different pattern + seam, and it tracks the view because the fan's S/T depend on camera orientation. (On N64 this draw is a verbatim RDP `G_TRI_SHADE_TXTR` coefficient block with no s16 tc — the overflow constraint is a port artifact of re-emitting as `gSPVertex` batches, same class as D227.) | **OPEN — REOPENED (M-116 live playtest, same session): the `allowShift=TRUE` mechanistic fix below did NOT resolve the symptom.** User report on Frigate post-fix: water still "glitches, kinda goes back and forth between two graphics too quickly," and still "changes depending on your view unlike the sky" (i.e. the sky, using the identical `skyPortBeginFan`/`skyPortEmitTileShift` mechanism post-D227, no longer has this problem, but water still does after getting the same treatment). This means the `allowShift=FALSE→TRUE` change either isn't the actual fix, or there's a second mechanism specific to water's two-texunit cross-fade that the tc-shift alone doesn't address — most likely candidate: the shift only rescales the *shared* vertex tc uniformly, but the tile-0-vs-tile-1 sample-point difference is set by each tile's own `uls`/`ult` (RDP tile-space, not vertex-tc-space) — if per-frame `k` changes granularity of the *quantized* shared coordinate before each tile's independent `uls`/`ult` subtraction, the two tiles' effective sampled texel could drift relative to each other frame-to-frame in a way the static `GE_D227V` trace (single frame, single camera angle) never exercised. Needs a fresh live investigation, not a repeat of the same static-trace approach — a scripted or live multi-frame capture while rotating view, watching both tiles' *decoded* texel positions (not just vertex tc) frame over frame. Do not re-apply the same `allowShift=TRUE` reasoning without new evidence; the superseded mechanism write-up below is unconfirmed-by-playtest and may be wrong. The code change (`allowShift=TRUE` on the water quad) is left in place — it's not shown to be actively harmful, and reverting it isn't obviously better than leaving it, pending the fresh investigation. **Superseded analysis (unconfirmed by playtest, kept for reference):** ~~FIXED (port-layer, `src/game/sky.c`, `#ifdef PORT`) — confirmed the `allowShift=FALSE` tolerance was the cause, and the "flattens the cross-fade" objection was wrong.~~ Changed the water quad's call from `skyPortBeginFan(sp274, s1, FALSE)` to `..., TRUE)`, so it now gets D227's tc-shift safety valve like every other sky fan. Why the old objection doesn't hold: `skyPortEmitTileShift` replays **both** tiles' captured `SETTILE` commands with the identical `k`, so both texunits' decoded S/T are rescaled by the same `2^k` *before* each tile's own (unshifted, tile-native) `uls`/`ult` offset is applied by the RDP — the offset between tile 0 and tile 1's sample points (what drives the cross-fade) is preserved, not flattened, because the shift and the offset act at different stages. **Verified mechanistically:** `GE_D227V=1` on Frigate (`-level_26`) shows a water fan vertex spanning S=-166..299317, T=-6451..288410 in S10.5 units — tens of thousands of texels, the same order of magnitude as D227's pre-fix sky overflow — now getting `kS=4 kT=4` (previously forced to 0), decoding to small in-range tc values (100s, not wrapped). **Verified no regression:** `verify.sh frigate` and `verify.sh "surface 2"` (the two `IsWater` levels) both PASS crash-free post-fix; non-water sky levels (`statue`/`-level_22`) unaffected since only the water call site changed. Screenshot comparison at a fixed scripted-intro camera angle (frame 500, both builds) showed no regression, but that specific angle didn't happen to frame the overflowing part of the fan either before or after — the sinf()-driven cross-fade also makes frame-for-frame screenshot diffs across separate runs noisy (each run's shimmer phase differs), so a same-frame pixel diff wasn't a clean confirmation tool here; the `GE_D227V` trace is the real evidence — **but it turned out not to be evidence the fix actually worked in live play.** Cross-ref D227 (mechanism), D229 (made this visible). | -| D246 | **Tiny pixel strips at the left and right edges of the screen, "like overscan" — look like raw pixels, not 3D graphics (M-116, user QA report).** Uninvestigated. The port renders at native 640×480 (`GE_NATIVE_W/H`; `gfx_current_native_aspect` set in `port/src/video.c:253,570`) and scales to the window on present, so the leading candidate is a scaling/blit rounding artifact: non-integer scale factors leaving 1–2 columns of uncleared backbuffer content at the edges (or an off-by-one in the blit rect). Secondary candidates: an RDP fill-rect/scissor off-by-one in a game DL or the F10 overlay hook (`gfx_run()` seam, D184), or GL edge filtering on the scaled texture. | **OPEN — one candidate ruled out (M-116 follow-up), root cause not found.** Step (1) from the original plan is done: a `GE_PCDUMP` capture (Frigate, native 640×483 buffer, both against the existing save and a fresh EEPROM) shows clean, continuous scene content in the leftmost/rightmost columns — no dead/black/garbage strip at either edge. That means the defect is **not** baked into the native render itself (rules out an RDP fill-rect/scissor off-by-one in a game DL, and rules out D227/D245-style tc issues) — it must be introduced later, specifically in the SDL-window presentation path that `GE_PCDUMP` bypasses entirely (`gfx_run()` reads back the game's own render target directly, never the actual window backbuffer the user sees). Re-examined `gfx_adjust_viewport_or_scissor` (`gfx_pc.cpp:2174`): its floor/ceil rounding is already deliberately anti-gap (comment: "prevents sub-pixel gaps at viewport edges"), so a plain rounding bug there is a weaker lead than it looked; more likely candidates now are the `game_renders_to_framebuffer`-path MSAA resolve `glBlitFramebuffer` (`gfx_opengl.cpp:1252`, only exercised when `Video.MSAA>1` or the window size actually differs from the game's target size mid-frame — a path `GE_PCDUMP`'s headless capture doesn't exercise the same way a live resizable window does) or a genuine sub-pixel/DPI scaling remainder specific to the user's actual window dimensions. **Next, still needs the user (no live window access in this environment):** (1) confirm current `Video.MSAA` setting and window size/aspect at the time the strips were seen; (2) if `MSAA>1`, retest with `Video.MSAA=1` to see if the strips disappear (isolates the resolve-blit path); (3) report whether the strip width changes with window size (fixed 1px = blit-rect off-by-one; scales with window = scale-factor remainder). Cross-ref D247 (separate, now closed — don't conflate the two; D247's letterbox is confirmed-intended and top/bottom only, D246 is left/right and still unexplained). **M-141: Steam Deck playtest confirmation, new platform data point** — user reports "some artifacts left and right of screen, only a sliver... like the fullscreen isn't quite going to full screen" specifically in **Full Screen mode on Steam Deck**. Same symptom description as the original M-116 report (Windows). Checked: the Deck's own first-run preset (`videoApplySteamOSDefaults()`, `port/src/video.c:255`) sets `cfgMSAA = 4` by default — exactly the condition this row already flagged as the leading remaining suspect (the MSAA-resolve `glBlitFramebuffer` path, step 2 of the still-open bisection ask). Next: have the user set `Video.MSAA=1` via F10 and retest on the Deck specifically — if the strips vanish, this row's root cause is confirmed without needing any more code tracing. | -| D247 | **Black bars top and bottom of screen — possible aspect-ratio defect (M-116, user QA report).** Uninvestigated. Context: the port currently renders native 4:3 (640×480); widescreen is a *parked proposal* (`docs/dev/WIDESCREEN-FOV-PLAN.md` — PD-parity native 16:9 render, needs rule-#2 sign-off for its game-code HUD wave), so if the user's window/display is wider than 4:3 and the present path letterboxes to preserve aspect, the bars are current intended behaviour rather than a bug. If they appear in a 4:3 window too, it is a real defect (framebuffer sized wrong vs window, `videoCreateFramebuffer(w,h,upscale,autoresize)` → `gfx_create_framebuffer`). | **NOT A BUG — confirmed faithful, unmodified N64 decomp behaviour, no code change made.** `GE_PCDUMP` captures (both against the pre-existing save and a fresh-EEPROM run, to rule out a stale `Screen` option from earlier test sessions) show the exact same inset on Frigate: real scene content occupies rows ~20–459 of a 640×483 capture (the 483 vs 480 is a separate, harmless 3-row capture-tool rounding quirk, not investigated further), i.e. roughly 220/240 of the vertical field — and `src/game/fr.h:34` defines `VIEWPORT_HEIGHT_DEFAULT_NTSC 220` (240 for the full field), consumed unmodified by `bondviewGetCurrentPlayerViewportHeight()` (`bondview2.c:7858`) as the **default in-game viewport height whenever `PLAYER_OPTION_SCREEN` is `SCREEN_SIZE_FULLSCREEN`** (the decomp's own default value, `options.c:128`) — `VIEWPORT_HEIGHT_FULLSCREEN` (304, no inset) is a red herring name; it's only reachable via the `cameraBufferToggle` branch, not normal solo play. This is GoldenEye 007's well-documented original TV-safe-area letterboxing, baked into ground-truth decomp constants with no `#ifdef PORT` anywhere near it — the N64 game genuinely doesn't fill the full field during normal gameplay. Ruled out a stale/leftover EEPROM `Screen=Wide/Cinema` setting from earlier QoL-testing sessions as an alternative explanation: a fresh EEPROM (default options) shows the identical inset. **No fix needed; this row closes.** If the user's window shows noticeably *thicker* bars than this ~8–9%-per-edge margin, or bars appear on the *sides* instead of top/bottom, that would be a genuinely different (and real) symptom worth reopening under a new label — but "thin bars top and bottom, present at any window size" is correct, original behaviour. Cross-ref D226 (separate, already-tracked HUD-scale QoL ask — unrelated mechanism, don't conflate). | -| D248 | **Port runs a stable 30 FPS instead of 60 FPS game-wide (M-117, user asked to verify FPS after the D209 timing-keystone fixes).** The port's pacemaker (`port/src/libultra.c` `portTickThread`) posts a VI-retrace event at a true 60Hz (NTSC) cadence, so the halving had to be somewhere downstream of that. | **FIXED, root-caused to a genuine pointer-width ABI bug in `src/sched.c` (compiled for the PC build, not excluded).** `osScAddClient()` (`src/sched.c:187-199`) stashes a per-client "present every retrace vs. every other retrace" flag by writing into the *next array slot's* `.next` field (`c[1].next = next`) rather than adding a real struct member — `gfxClient` (`src/init.c:246`) is registered with `next=NULL` (send every retrace → 60Hz) and the audio client `g_AudioClient[0]` (`src/audi.c:441`) with a nonzero sentinel `1` (send every other retrace → 30Hz, its intended cadence). `__scHandleRetrace` (`src/sched.c:334`) reads that flag back with a hardcoded byte offset, `*((s32*)client + 2)` (2×`sizeof(s32)` = 8 bytes). On the N64 (32-bit pointers) `sizeof(OSScClient)` is exactly 8 bytes, so offset 8 correctly lands on `client[1].next` — matching the write. On this 64-bit port `sizeof(OSScClient)` is 16 bytes, so the same hardcoded 8-byte offset instead reads the low 32 bits of `client->msgQ` itself (always a real, non-NULL pointer) — the gfx client's flag reads as permanently "nonzero" and silently falls onto the audio client's every-other-frame path, halving the game's real render/tick cadence to 30Hz although the retrace pacemaker itself was always ticking at the correct 60Hz. Same D122/D126/D132/D209 bug class (32→64-bit pointer-width struct-size growth desyncing a hand-rolled offset), just in the scheduler instead of a ROM-serialized struct. **Fix (`#ifdef PORT`, N64 line kept verbatim under `#else`):** read the real field by indexing the struct (`client[1].next == 0`) instead of hardcoding a byte offset — this naturally scales with pointer width on either platform and is the direct decompilation of what `osScAddClient`'s write side already does. **Verified:** `Video.DisplayFPS=1` overlay (`port/src/optionsoverlay.c`, D213) read a rock-stable "30 FPS" on `-level_09` (BUNKER1) pre-fix and "60 FPS" post-fix, same build/scene, screenshots captured via `GE_PCDUMP`. Rebuilt clean (`ninja -j1`, pre-existing unrelated warnings only); `-level_09` and `-level_20` both ran 12-30s post-fix with no crash (`ge007.crash.log` absent). No game-code files touched beyond this one mechanical read (`src/sched.c` is compiled for the PC target per `CMakeLists.txt`'s `SRC_ENGINE` list, not one of the excluded os/io files) and the audio client's own flag/path is completely untouched, so `#ifdef PORT`-gated audio pacing (D204 tempo work) is unaffected. **Note for `docs/dev/UNLOCKED-FPS-PLAN.md`:** this settles that plan's Phase 0 open question — the ~30fps default was a real port bug, not original N64 behavior or an artifact of retrace-rate tracking sim speed; the plan's default-preset baseline should be re-measured at the corrected 60fps before Phase 1 pacing work resumes. Not yet done: a full `verify.sh sweep` across all 21 levels (only `-level_09`/`-level_20` spot-checked this session) and a live human playtest for feel (input latency, animation smoothness, any level-specific perf regression now that render work happens twice as often per second). | -| D249 | **LOD/culling breaks down on large open levels (Streets, Egyptian named specifically) at *default* FOV — far-away geometry has visible culling issues (M-119, user QA report).** Distinct from **D222** (which is specifically high `Video.FovScale` breaking *near-screen-edge* culling on NPCs/objects — not implicated here, default FOV) and from **D218** (the fog/far-clip *tint* boundary at wide FOV — also not the same symptom). This report is at the stock FOV, on the game's two biggest/most-open outdoor-scale levels, affecting *far* geometry specifically — points at either (a) a portal/room-visibility BFS cutting off too aggressively at range on large multi-room layouts (same neighbourhood as D233/D234's near-camera portal-cull bugs — worth checking whether D233's `gfx_sp_tri1` w<0 trivial-reject fix, which only guarded *behind-camera* vertices, has a sibling far-plane/depth-range case), or (b) GE's own N64 LOD/detail-swap system (mip-tile / simple-model substitution at distance — see D218's still-open question of "does GE have a separate geometry/object LOD-swap distinct from `Visibility.FarFog`") not being ported faithfully, popping or dropping geometry instead of swapping detail level. **Second, separate ask bundled in the same report:** the user would like LOD **improved** in general (presumably distance-based detail transitions look rougher/more abrupt on PC than remembered) but explicitly wants this **gated behind a toggle** so the original N64-accurate LOD behaviour stays selectable ("in case you want old school graphics") — i.e. this is a QoL feature request layered on top of a correctness bug, not one fix. | OPEN — not investigated. Next: reproduce on Streets (`-level_20`) and Egyptian (`-level_08`, confirm level id) at default `Video.FovScale`; `GE_PCDUMP` a long sightline where geometry visibly drops/pops, cross-referencing whatever governs GE's LOD-tile selection (`gfx_lod_tile_offset` family, already touched by D172/D219) and the portal/room-visibility walk (D233/D234 neighbourhood) to determine which of (a)/(b) is actually firing before designing a fix or the requested toggle. | -| D250 | **FPS is inconsistent/low on many levels since the port started actually running at 60fps — drops to 20–40fps intermittently, described as worse than before (M-119, user QA report, follow-on from D248).** Very likely a direct consequence of **D248** shipping: the port's render+tick loop had been silently running at half rate (30Hz) for the entire life of the project (D248, M-118) — the *real* per-level CPU/GPU cost of rendering and simulating this port was always this high, it was simply invisible while D248 halved the work being asked of the hardware every second. D248's own write-up flagged this as an open risk ("any level-specific perf regression now that render work happens twice as often per second") and explicitly left a live playtest / perf pass as un-done. Not yet investigated which side (CPU sim, CPU fast3d command generation, or GPU draw) is the bottleneck, or whether it's uniform or level-specific (the user's report implies specific/intermittent, which fits a per-scene cost — draw-call count, overdraw, or a specific expensive subsystem — rather than a flat doubled baseline cost). **M-120: partial progress, real bottleneck not yet caught.** User report sharpened: ~45fps at 720p on a self-described high-end PC, present even outside of dedicated stress levels — worse than the coarse "many levels, intermittent" framing suggested. Two things ruled out this session: (1) **build flags are not the cause** — `build-pc/CMakeCache.txt` confirms `CMAKE_BUILD_TYPE=RelWithDebInfo` (`-O2 -DNDEBUG`) is the actual default (`CMakeLists.txt:75-76`, unconditional unless a cache already exists), matching what `./build-pc.sh` produces with no extra flags — a debug/`-O0` build is not the explanation. (2) **idle-load is not the bottleneck, at least not in this dev box:** `GE_D193=1` on `-level_09` (BUNKER1, small level) idles at a rock-steady `render=60 sim=60`, frame-render time ~2.5 µs·10^3 (2.5 ms); `-level_29` (STREETS, one of D249's flagged large/open levels) idles at `render=55-60 sim=60-62`, frame-render time 6-7 ms — both comfortably under the 16.7 ms/60fps budget with no catch-up clamp hits. **This does not reproduce the user's 45fps** — either the real cost only shows up under actual gameplay load (AI/combat/particles active, not an empty idle scene — matches D193's own "player fine, AI-driven cost is different" pattern) or it's resolution/GPU-fill-rate-bound in a way this box's small idle test window doesn't exercise (this session could not drive real keyboard/mouse input into the game to generate a loaded scene — no interactive input tooling available headlessly). Also spotted and ruled out in passing: the `D51 vi post` debug log firing every render frame in `port/src/libultra.c:781` is throttled to ~once/sec (`% 60 == 1`), not a per-frame cost — not the culprit, though it's a `TEMP D51` instrument that's been live since early porting and could be removed as cleanup. **M-120 continued, live session with the user driving the game directly — the sim/render split is now confirmed live, and several strong candidates are ruled out, but the actual cost is still unlocated.** Reproduced directly on Dam (`-level_33`): `sim` holds a healthy 59-67/s throughout, `render` sags to 45-50/s, and the CPU-side `frame rendered in Nus` cost (`gfx_run`'s software-RSP interpretation, `port/src/libultra.c:1252`) stays only 6-10ms the whole time — comfortably under the 16.7ms/60fps budget. That leaves a genuine, unexplained ~10-15ms/frame, and a live A/B pass ruled out every obvious GPU-side suspect one at a time, each via the F10 in-game overlay while watching `GE_D193`: **MSAA 2→1 and Anisotropy 16→1 — no change.** **FovScale 125→100 — no change.** **VSync 1→0 (true uncapped rendering) — render still pinned at ~60 max, never higher, and the bad-scene numbers were unchanged** (also tells us the ~60fps ceiling itself is not a vsync artifact — something else already caps the loop at 60, vsync or not). **Resolution 1280×960 fullscreen → 640×480 windowed — no change** (rules out GPU fill-rate/pixel-count entirely; the cost does not scale with pixels at all). **Found and fixed a real, separate bug in passing (did not turn out to be the active cause here):** `sync_framerate_with_timer()` (`port/fast3d/gfx_sdl2.cpp`) computes the remaining frame budget in 100ns units (`qpc_to_100ns`) and passes it straight to `sysSleep()`, which takes **microseconds** — a genuine 10x oversleep whenever that branch fires. Fixed (`left / 10`). But this path only runs when `target_fps` is nonzero (tied to `Video.FpsCap`), and the user's test config had `FpsCap=0`/`VSync=0` — confirmed live that the bug fix made no difference to the reported drops, because the buggy code path was never executing in that config. Still worth landing as a correctness fix for whenever `FpsCap`/`VSync` *is* active. **Added `GE_D250`** (`src/boss.c`, wraps `lvlRender()`, the DL-building/culling/scene-traversal step that runs *before* `gfx_run()` and is separate from it) to check whether DL-building was hiding the missing time — live-tested on Dam: **`lvlRender` averages only 0.5-1.5ms, also not the bottleneck.** So: known costs (`gfx_run` ~6-10ms + `lvlRender` ~1ms) sum to ~7-11ms, real frame period is ~20-22ms (45-50fps) — the remaining ~10-15ms/frame is resolution-independent, GPU-setting-independent, and not in either of the two obvious CPU call sites. Traced the dataflow one level further: the game's main loop (`src/boss.c` `bossMainloop`) blocks on `osRecvMesg(&gfxFrameMsgQ, ..., OS_MESG_BLOCK)` waiting for `OS_SC_RETRACE_MSG`, posted by a dedicated pacemaker thread (`portTickThread`, `port/src/libultra.c`) at a fixed cadence independent of how fast the consumer drains it — meaning the observed render rate is whatever the consumer (game+render loop, one OS thread hop away from the pacemaker) can actually sustain, not a directly-configured cap. **Leading remaining suspect: the emulated N64 inter-"thread" message-passing/scheduler round-trip itself** (`port/src/gesched.c`/`sched.c`, real OS threads + mutex/condvar standing in for the N64's cooperative SP/DP/main threads) — each hop (game thread → scheduler → SP "thread" → done-message back) is a real OS context-switch-and-wake, and Windows condvar/thread wake latency can easily run several ms per hop, unlike the free N64 hardware handoff this code was ported from. **Not yet confirmed** — this needs either a targeted timer bracketing the full scheduler round-trip (same technique as `GE_D250`, just at a different call site) or a real sampling profiler (Visual Studio's own, or Windows Performance Recorder/WPR) attached to `ge007.x86_64.exe` during a live bad-fps moment, which would show this directly without more printf-probe guessing. Ad-hoc per-call timers have now ruled out the two most obvious candidates without finding the cost; a real profiler is the better next tool. **M-120 — ROOT-CAUSED AND FIXED: `getenv()`.** Set up a real profiler as recommended (`tools_pc/perf.ps1`, new sister script to `debug.ps1`, wraps `xperf` CPU-sampling + context-switch tracing). A live WPR/xperf capture on Dam, with Microsoft's public symbols resolved (`-symbols`, downloads system-DLL PDBs), showed the dominant render thread spending only **5.2% of its CPU time in the game's own code** — **43% was in `msvcrt.dll`**, and within that, `getenv()`/`_getenv_helper_nolock` alone accounted for **~50% of the thread's entire CPU time**. Root cause: `port/fast3d/gfx_pc.cpp`'s `import_texture()` (runs on every texture bind) and several per-triangle/per-`G_SETCOMBINE` combine-mode probe checks (`GE_DTEX`, `GE_TEXDUMP`, `GE_TEXRAW`, `GE_D229` ×2, `GE_D172` ×2, plus `GE_TEXDUMP`/`GE_PCDUMP` in `gfx_opengl.cpp`) called `getenv()` **uncached, every single call** — unlike the safe `static int x = -1; if (x < 0) x = getenv(...) != NULL;` pattern already used everywhere else in this codebase (`ft_d193`, `ge_d116`, `dvm`, etc.). On a texture-heavy scene this is tens of thousands of Windows CRT environment-lookup calls per second (each a locked, locale-aware linear scan per Microsoft's msvcrt implementation), completely invisible to both of M-120's earlier timers (`gfx_run`'s "frame rendered in Nus" and the new `GE_D250` `lvlRender` probe) because neither one specifically isolated CRT/library time from the game's own code. **Fix:** cached every uncached `getenv()` site in `gfx_pc.cpp`/`gfx_opengl.cpp` with the established pattern — narrow, mechanical, zero logic change. **Verified:** the exact idle-Dam headless test that was pinned at 45-50fps before the fix now holds a rock-steady 60-61fps, zero dips, with no other change. This also retroactively explains why M-120's earlier resolution/MSAA/vsync A/B pass (all "no change") was so consistent — the `getenv()` cost was a large, *per-call* (not per-pixel) constant that swamped any smaller resolution-dependent GPU cost at every setting tried, so the A/B genuinely couldn't have detected a fill-rate difference underneath it. **User re-tested 1440p/4K after the fix and confirmed it's fine too** — the initial "still runs badly at 1440p+" report was from before this fix landed (a stale-build mixup, same class as the DLL-load-error false alarm earlier in this session); once actually re-tested on the fixed build, high resolutions hold up fine. **D250 fully resolved, all resolutions tested clean.** | -| D251 | **F10 options overlay QoL pass: (a) bottom rows drawn off-screen in the in-game 2D space — the layout assumed a ~320×240 field and hard-fit all rows, but `viSetXY` gives 440×330 on front-end screens (`src/game/front.c:8618`) vs 320×240 in-game (`front.c:8628`), so with 17 rows × 15u pitch + 2 header rows the last rows land at y≈282, off-screen whenever the panel is opened in-level; (b) MSAA row only cycled forward — `rowAdjust()`'s `ROW_MSAA` case clamped its index to [0,3] instead of wrapping, so left-click stuck it at 8x with no way down via clicks; (c) manual % rows (`Video.DrawDistance`/`Video.LodDistance`) showed unconditionally even while their `*AutoFov` toggles were on, where the percent is inert/misleading. | **FIXED (port-only, `port/src/optionsoverlay.c`).** (a) The panel now computes how many rows fit the *actual* current 2D height (`maxVisibleRows()` from `viGetY()`) and scrolls: a visible-row window (`s_scroll`) follows the selection, driven by wheel (`optionsOverlayScroll`) and arrow/D-pad at the list edges; layout, mouse hit-testing (`overlayRowAtY` now returns a visible position) and keyboard nav all index the visible list (`s_visIdx`/`s_visN`, `s_sel` is now a visible-list index), so it fits both 240- and 330-tall spaces with no per-space tuning. (b) `ROW_MSAA` wraps `(idx + dir + 4) % 4` — OFF→2x→4x→8x→OFF in both directions, matching the already-wrapping `ROW_ENUM`/`ROW_RES`; sliders keep clamping (standard for drag-able values). (c) New `Row.hiddenIfOn`/`hidePtr` fields: a row is hidden while the named option is nonzero — `Draw distance %` hides under `Video.DrawDistanceAutoFov`, `LOD distance %` under `Video.LodDistanceAutoFov`; rebuilt every frame in `overlayUpdateVisible()` (selection clamped into range when its row vanishes). Hint line updated to "click / drag / arrows / wheel". **Verified:** compiles clean in the full 241-target build; final link of this session was blocked only by a running game instance holding the exe (re-link pending). Not yet eyeballed live: scroll feel at 320×240, hover/scroll interaction, and the auto/% row appear-vanish transitions. Cross-ref D213 (FPS readout in the same file), D218/D249 (the auto-coupling these rows expose). **Follow-up after live test:** (d) list navigation (wheel + arrows) wrapped at both ends, so scrolling past the bottom made the highlight "repeat" from the top — now clamped at both edges like a normal PC settings list; (e) new `Input.SensLink` toggle (default ON, registered in `port/src/input.c`) links the aim/turn sensitivity knobs: moving either rescales the other to hold the stock 38 (`Input.AimModeSens`) : 50 (`Input.MouseTurnSpeed`) ratio, via a re-entrancy-guarded pair-write in `rowSet()`; (f) the "Mouse aim speed" row now edits `Input.AimModeSens` (the knob the default GEPD aim path actually uses — it previously edited `Input.MouseAimSpeed`, which only feeds the legacy velocity-stick fallback and was inert under default settings). **Second follow-up:** hover-to-highlight removed entirely -- moving the mouse over the panel no longer moves the selection or scrolls; near a list edge the hover->select->scroll-shift->new-row-under-cursor feedback loop made the bottom of the list twitch/echo (the persistent "duplicate row" report). Selection now moves only by explicit click (which also selects the clicked row), wheel, or arrows. **Reassessment of the 4K-fullscreen ghost-row bug:** the presentation-UV-wrap theory is DEAD — `gfxFramebuffer` has zero readers (the textured-quad present never happens); presentation is a full-frame `glBlitFramebuffer` from the same-size MSAA FBO to the default framebuffer (fb index 0 is reserved for the window, `gfx_opengl_init`), which has no UVs and cannot wrap. The overlay DL draws each visible row exactly once, in-bounds, with its own scissor. Local repro (maximized 16:9 window + MSAA=4 + `GE_OPTIONSOVERLAY=1` + `GE_PCDUMP`) shows NO ghost — the FBO/MSAA path alone is not the trigger; the remaining variable is true fullscreen on the user's 3072×1728 display (driver/display-level suspect). Next: user bisection — Fullscreen ON + MSAA OFF (restart) → does the ghost persist? **User follow-up (logged, not fixed):** the 4K-fullscreen ghost is *intermittent* across launches, and the user suspects the `hiddenIfOn` appear/vanish transitions of the Draw/LOD distance % rows (visible-list resize while the panel is open) — unverified; note `overlayUpdateVisible()`+`overlayUpdateScroll()` are re-run together in both emit and input each frame, so a stale-state window would have to come from elsewhere (e.g. the one frame a row count changes). MSAA-off bisection still pending. User: in the sessions seen so far the ghost is present on *first open* of F10 (not only after an auto-toggle flip) — weakens but does not kill the appear/vanish theory (toggles had flipped in earlier sessions before a restart). **v0.2.0-pre playtest (user, latest build):** the symptom has changed — the panel's *bottom row now deterministically duplicates whatever item is currently selected* (e.g. MSAA appears both on its own row and again at the bottom), not just an intermittent 4K/MSAA ghost of the top row; suggests the visible-row window can contain the selected row twice (off-by-one in `overlayUpdateScroll`/`maxVisibleRows` bookkeeping) — investigate post-release. **QoL follow-up:** make the auto-linked % rows visually subordinate to their toggle (indent and/or dimmer value colour) so the pairing is obvious in the panel; hint line also reworded to "select: scroll/click, change: mouse/arrows". | -| D252 | **Particle effects cycle through a rainbow palette (M-124, user playtest of the v0.2.0-pre candidate).** Shooting repeatedly makes the bullet-impact "sparks" slowly progress through the full hue wheel (~10 shots to sweep it); other lingering particle effects — smoke / explosion residue — show the same rainbow colouration instead of their intended grey/orange palette. **Mechanism context (verified this session):** particle tris carry no per-primitive material; their colour comes entirely from the ROM-resident state records `globalDL_0x078 … globalDL_0xa50` (`assets/oddtextures.c`, 15 of them) replayed per particle batch (`explosion.c:894`). Each record binds a **distinct** texture pair — `IMAGE_SMOKE_N` (IA, tile 0 @ TMEM 0) × `IMAGE_FIRE_N` (RGBA16, tile 1 @ TMEM 0x188) under `G_CC_INTERFERENCE` (TEXEL0·TEXEL1), and `explosionRenderPart` uses a fixed all-white default vertex (`explosion.c:215`) — so the intended per-stage colour is whatever those 15 fire/smoke pairs encode, and particles **age through the records** (`var_s2` 14→0 at `frame/flareanimspeed`), so a per-texture decode error surfaces exactly as a hue sweep over time / across shots. **Ruled out this session:** (a) the M-82/D172 tile-offset fix is correctly configured for this path — `gsDPSetTextureLOD(G_TL_TILE)` does NOT set the `G_TL_LOD` bit, so `rdp.tex_lod` stays false (`gfx_pc.cpp:2860`) and `gfx_lod_tile_offset` returns `i`, i.e. TEXEL1 genuinely samples tile 1; (b) the RGBA16/5551 texel decode in `import_texture_rgba16` is correct (big-endian, R=bits15-11 G=10-6 B=5-1 A=bit0). **Prime suspect: the width/height derivation in `import_texture_rgba16`** — `width = rdp.texture_tile[tile].line_size_bytes / 2`, `height = size_bytes / line_size_bytes`. The fire tiles are 16 px wide with a MASK_16 TMEM line (64 bytes), so `width` computes 32 (true: 16) and, with `size_bytes` = the LOADBLOCK's 16×14×2 = 448, `height` computes 7 (true: 14) — the GL texture would be built from the right pixels at the wrong dimensions, scrambling each of the 15 fire sprites into a different wrong-hued smear; that fits "slow rainbow progression" precisely (each aging stage = a different scrambled sprite). **Not yet confirmed** — needs one imported fire tile dumped and compared against the raw `IMAGE_FIRE_N` bytes (`GE_TEXDUMP`/`GE_PCDUMP`, or a targeted probe at the `upload_texture` call). **Per user instruction: documented only, NOT fixed for v0.2.0-pre** — ships as a known issue; pick up afterwards (cheap if the suspect holds: derive width/height from the LOADBLOCK's dtx/dlh rather than the tile line size, or special-case non-32-texel-wide RGBA16 tiles). D172/M-82 lineage. **M-141 update: the width/height suspect is REFUTED by the authored asset data, not just re-tested — the prior "prime suspect" reasoning assumed `line_size_bytes` derives from the tile's `MASK_16` wrap period (64 bytes ⇒ 32 texels), but `assets/oddtextures.c`'s actual `gsDPSetTile` for the RGBA16 **render** tile (tile 1, e.g. `globalDL_0x078:50`) sets `line=4` explicitly (independent of the mask), giving `line_size_bytes = 4*8 = 32` bytes ⇒ `width = 32/2 = 16` texels — and `size_bytes` from the paired `gsDPLoadBlock(...CALC_LRS(16,14,G_IM_SIZ_16b)...)` is 16×14×2 = 448 bytes ⇒ `height = 448/32 = 14`. `import_texture_rgba16`'s existing `width = line_size_bytes/2` / `height = size_bytes/line_size_bytes` formula therefore computes the CORRECT 16×14 for every fire tile, cross-confirmed by the pre-existing `is_fire_shape = (width==16 && height==14)` filter already hardcoded into `gfx_opengl.cpp`'s `GE_TEXDUMP` dumper (D219-era) — that filter only makes sense if 16×14 is what the importer actually produces at runtime. **Do not chase width/height again.** Also checked and rejected: the render tile's `gsDPSetTileSize(1,...,CALC_TILESIZE(56),CALC_TILESIZE(56))` sets a 56×56 texel-coordinate WINDOW for UV-wrapping the 16×14 content against the co-rendered 56×56 smoke texture (`G_CC_INTERFERENCE`, TEXEL0=smoke/TEXEL1=fire) — this is not a usable content-dimension source and switching to it (the naive "use SETTILESIZE instead of line_size_bytes" fix) would have made the bug worse, not better. **GEVR-TRIAGE item E (byte-group-order hypothesis) also does not apply new information** — the original session's decode-order check (still correct: `addr[2i]<<8|addr[2i+1]`, matches the already-fixed D228 IA16 sibling) stands; no runtime capture this session found a byte-order anomaly either (see below). **Root cause is now genuinely open, not "unconfirmed suspect"** — both named hypotheses are dead. Next investigator: the TMEM slot the fire render tile always loads into (`tmem=0x188`/392, `rdp.loaded_texture[]` indexed by tmem, hard-coded identically across all 15 `globalDL_0x078..0x9a8` records) is a plausible next avenue — 15 *different* ROM source images share one fixed TMEM address and one GL-cache key derived from `{texture_addr, fmt, siz, size_bytes, ...}` (`gfx_pc.cpp:~1962`); worth checking whether rapid record-to-record aging ever reuses a stale GL texture object keyed wrong, though this is an unverified new lead, not a confirmed mechanism. **Not runtime-confirmed this session** — added an env-gated diagnostic (`GE_D252=1` in `import_texture_rgba16`, `port/fast3d/gfx_pc.cpp`) that logs computed vs. SETTILESIZE dimensions and dumps raw texel bytes per distinct upload to `scratch/d252_raw_*.bin`, but two 35s/90s headless `-level_37` (Jungle) runs never triggered an explosion/fire draw (no player input available in this environment) — needs an interactive session or a longer/different-level run to actually fire the probe. **User-confirmed live, same session: still reproduces on plain bullet-impact sparks**, not just explosions — this is a much cheaper repro than an explosion (any gunshot against a wall/surface) and should be the target for the next `GE_D252=1` capture, not a scripted explosion. | -| D253 | **Facility (and any level with a FORCECROUCH/LADDER linked special tile) SIGSEGV on Linux/Steam Deck — `stanCheckLinkedSpecialTile` stores to a garbage `outFlags` pointer (D203 root cause).** The B-callback typedef `standTileLocusCallback_B_t` (`bondtypes.h:573`) declares the middle three params as `f32 f32 f32`, so on x86-64 SysV the caller (`sub_GAME_7F0B1DDC`, `stan.c:2228`) passes the 6th arg (`record`) in **`%rdx`** (3rd integer slot; the floats take xmm0–2). But the actual implementation `stanCheckLinkedSpecialTile` was decompiled with an all-`s32` prototype, so it reads `outFlags` from **`%r9`** (6th integer slot) — a stale scratch value left by earlier callees. On the N64 (MIPS o32) both prototypes agree: everything flows through GPRs a0–a5 in order, 6th arg = a5 either way, so the original is fine and the decompilation looked consistent. The mismatch stays dormant until a tile actually hits the FORCECROUCH or LADDER branch and *stores* through `outFlags` → SEGV; that's why it was level-specific (Facility's opening crouch tile) and input-dependent, and why idle repros were negative. The sibling B-callback `stanLocusEdgeIsAboveY` already had the correct float prototype, which is why only this path was booby-trapped. **Fix (ABI-class, semantics-preserving):** declare the three middle params of `stanCheckLinkedSpecialTile` as `f32` in both the forward decl and definition (`stan.c:152`, `stan.c:2407`) to match the typedef; the body never uses them, and on N64 o32 f32 args occupy the same GPRs, so N64 codegen is unaffected. **Verified:** gdb run on WSL (gcc 15) — pre-fix, SIGSEGV at `stan.c:2441` with `r9=0x3` and valid `record=0x409fea00` in the caller frame; post-fix, the same walk route completes with no crash. Side benefit: the FORCECROUCH/LADDER branches were effectively dead-on-arrival on PC (any hit = crash); they now function. **Also observed post-fix (separate, WSLg-only):** a segfault *inside libgallium* during `gfx_opengl_upload_texture` (32×48 RGBA + mipmaps) while walking further — GL-driver-side under WSLg's Mesa; not reproducible on Windows; park as a new finding if it recurs on real hardware. | FIXED — Deck-verified: user got past the crouch tile with the re-cut bundle (a *new*, later crash is D255). | -| D254 | **Linux crash handler destroyed its own logs: `ge007.crash.log` only ever contained the SIGABRT block, never the original SEGV.** The POSIX `crashHandler` (`port/src/crash.c`) finished by calling `sysFatalError()` → `abort()` → SIGABRT, which re-entered the *same* handler (SIGABRT was one of the installed signals); the second pass reopened the log with `"wb"` and overwrote the first pass's SEGV block — faulting PC, signal, everything. The Deck firefight crash (D255) came back as a bare `SIGNAL: 6` abort record for exactly this reason, forcing offline disassembly of the CI binary to recover what the log should have said. **Fix (port-only):** re-entrancy guard (`inCrashHandler`, second pass `_exit(128+sig)` immediately) + terminate directly with `_exit()` instead of `sysFatalError()` (the Windows path already terminated directly for the same reason) + the Linux block now dumps the faulting context: `FAULT ADDR` (`si_addr`) and the full general register set (Rax/Rcx/Rdx/Rsi/Rdi/R8–R11, Rsp/Rbp) from the `ucontext`, so a field crash now names the bad pointer on its face. **Field-verified 2026-09-13:** the D255 Deck crash came back as `SIGNAL: 11` + `FAULT ADDR: 0x10` + full register set — exactly the format designed here; it directly identified the NULL-model case (see D255). | FIXED — field-verified. | -| D255 | **Facility firefight SIGSEGV on Steam Deck (v0.2.0-pre CI bundle, D253 fix confirmed working — user got past the opening crouch tile).** Crash during gunplay; abort-unwind backtrace points at `sub_GAME_7F09BAC4` (`vtxstore.c:158`) ← `sub_GAME_7F09BBBC` (`:220`) ← `lvlManageMpGame` (`lv.c:1302`) ← `bossMainloop` (`boss.c:567`). Disassembling the exact CI binary at the fault PC (`0x200db135`) gives `mov 0x14(%rax),%edi; mov 0x10(%rdi),%rax`: the function walks the active PropRecord list keeping `type == 1` — which is **PROP_TYPE_OBJ, not CHR** (the decompiler cast to the union's first member and misnamed the field `ChrRecord.chrflags`; it is actually `ObjectRecord.model` at `0x14`) — then dereferences `model->obj`. Two port-relevant wrinkles: (a) the load is **32-bit zero-extended** because the decomp types the field through the `CHRFLAG` enum, so a model pointer ≥ 4 GB would truncate to garbage; (b) the loop skips records whose `model->obj` is NULL but *dereferences* `model` unconditionally, so an active object with a NULL/freed `model` faults — plausible in a firefight where destructibles (crates etc.) die. Not reproduced on WSL after equivalent play. **Register capture (D254 format, 2026-09-13):** two more Deck crashes — Bunker mid-firefight, then Frigate with ~3 NPCs alive; log: `SIGNAL: 11 / FAULT ADDR: 0x10 / Rax=0x701e5f54 Rdi=(nil) / PC 0x200db135`. `Rdi` = the record's model value = **exactly NULL** → case (b) confirmed: an active PROP_TYPE_OBJ record with a NULL `model`, dereferenced by the unconditional `mov 0x10(%rdi),%rax`; truncation (a) and stale/garbage pointers are ruled out. Faulting PC matches the recorded disassembly (`sub_GAME_7F09BAC4` = `vtxstore_fix_refs`). Grep-verified: nothing in game code ever writes NULL into `ObjectRecord.model` — `clear_model_obj()` nulls `model->obj` only, and `objInit`/spawn paths only activate a record once model ≠ NULL — so the NULL comes from either a fresh/uninitialized record slot being activated or a destroy-path ordering race (model freed/nulled while the record is still active this tick). **Fix constraint:** any guard lands in game code (`vtxstore.c`) → needs rule-#2 sign-off; `port/` cannot intercept this dereference. Next: (1) decision on whether a NULL-model skip in `vtxstore_fix_refs` qualifies as an ABI-class exception (semantics-preserving defensive guard, PD analogue check); (2) if yes, add it plus a `#ifdef PORT` trace at the deactivation/model-free sites to name the path that leaves the record model-less. **Corrected, deterministic repro (v0.2.1 user testing, 2026-09-15, superseding the initial report): the trigger is Facility's computer terminals — the ones you ACTIVATE (interact with, not shoot/destroy) to open a door for level progression.** User confirms this is consistent/reliably reproducible on those specific terminals, on Steam Deck **and** Linux generally (not Deck-hardware-specific). This is a much stronger lead than the original "sometimes during firefights" — a terminal activation deactivating/freeing its associated object model while the record briefly stays active this tick is fully consistent with the destroy-path-ordering theory above, just via a scripted trigger instead of combat destruction, and gives a deterministic repro instead of a probabilistic one. **Next session should reproduce via terminal activation specifically**, not generic combat — much cheaper to instrument. **M-140: added a diagnostic probe (`GE_D255`, off by default, `#ifdef PORT`) — `vtxstore.c`'s `sub_GAME_7F09BAC4` now skips-and-logs instead of dereferencing when it finds a NULL model on an active OBJ record (identity + state fields), and `propobj.c`'s `objFree` logs every free call for correlation. Attempted a live Windows repro this session (5 terminal activations across 3 Facility launches, one direct `-level_34` boot each time): zero probe hits, zero crashes — Windows does not reproduce this, consistent with the existing WSL-negative result. Two negatives (WSL, native Windows) against one positive (Linux/Steam Deck) points at something genuinely platform-specific (allocator/timing), not a Windows-reachable path — don't spend further Windows session time chasing a live repro.** The probes are harmless (env-gated, zero behavior change when unset) and committed so a Linux/Deck session can set `GE_D255=1` and get the trace directly. **User report, 2026-09-15 (same day, later, real Steam Deck hardware on the published v0.2.1 release — unverified by this session, logging as reported, not re-asserting the activation theory as wrong):** Facility crashes **consistently on terminals being destroyed** (shot), not (only) on activation. Frigate crashed once during this same testing pass, specifics not recorded. Shooting terminals elsewhere/other attempts did not reliably reproduce. This is closer to the *original* pre-M-139 framing (combat/destructibles triggering the NULL-model race) than the M-139 "corrected, activation-only" theory — both are plausible triggers of the same underlying destroy-path-ordering race (any code path that frees/nulls an active OBJ record's model mid-tick), not necessarily contradictory. **Not yet reconciled or verified by a session with hands on the repo** — next Linux/Deck session should test both triggers (activation AND destruction-by-gunfire) with `GE_D255=1` set before revising the "reliable repro" framing again. **Reconciled, same day, further real-Deck testing (v0.2.1 published release): destruction is the trigger, not activation — confirmed across four levels.** Facility: **every** terminal crashes consistently when destroyed (not merely activated). Caverns: terminals near the radio objective crash when they explode — same mechanism, different level, rules out a Facility-specific asset/state bug. Archives: a **similar** crash when a guard's grenade detonates — same destroy-via-explosion mechanism, no terminal involved at all, which narrows the real trigger to "an object dying via explosion damage" in general, not anything terminal-specific. **Negative control:** shooting an entire room of terminals on Frigate did not reproduce it — so it isn't simply "any destructible OBJ record exploding" either; something about the specific object/scene state still gates it. Release notes updated to match (`.github/release-notes.md`, D255 bullet: "consistently crash the game when destroyed"). **Static lead for next session (untested, from this session's code read):** `objFree`'s destroy path (`propobj.c:1017-1039`, entered via `RUNTIMEBITFLAG_REMOVE` from explosion damage, `sub_GAME_7F04424C`/`sub_GAME_7F0442DC`) never explicitly nulls `ObjectRecord.model` — `clear_model_obj()` only nulls `model->obj`. The NULL therefore can't come from that assignment; it must come from either (a) `chrpropFree`'s freed slot being reused by `chrpropAllocate` for a *different*, not-yet-`objInit`'d record before `vtxstore_fix_refs`'s later same-frame pass reaches it (a stale-pointer/reuse race, not a field write), or (b) the active-list unlink (`chrpropDelist`) happening while some other code is mid-iteration over the same list (a modify-during-iterate bug) — explosion damage plausibly spawns new effect props (sparks/debris/smoke) in the same tick that immediately reuse the just-freed slot, which would explain why it's tied to *explosions specifically* and not simple destruction. **Next, concrete:** with `GE_D255=1` set (probes already in tree from this session, ship in any build off `release/v0.3.0` including the local Linux package built this session), reproduce on Facility from the Deck itself (Desktop Mode, launch from a terminal, redirect stdout to a file) and send the log back — the probe already logs the dying record's identity plus every `objFree` call, which should show whether the crashing record's `prop`/`obj` pointer address was recently freed-and-reused this same session. +| D165 | **Front-end menu cursor doesn't feel like a mouse pointer (M-31, user bug B5 follow-up).** — full `## D165` entry at file tail | FIXED (`port/src/input.c`; `Input.MenuPointerMode`, `Input.HipfirePitchSpeed` added).

On 32-bit N64 this is bit-exact (both the enum and a pointer are 4 bytes, so casting the enum's value to `Model*` reproduces the real stored bytes). On 64-bit PC, `Model*` is 8 bytes but the enum read is still only 4 — the cast reads just the pointer's low 32 bits as an `int` and zero-extends it back to a 64-bit address, discarding the real high bits entirely. This is the **exact D3x pointer-width ABI class** documented in AGENTS.md/porting-notes — a struct field misread across the 32→64-bit pointer-width transition — and it was *already flagged* as suspect (a) in this very row's first paragraph, back in the original v0.2.0-pre investigation, then wrongly deprioritized in favor of suspect (b) (the NULL-model theory) once a live register capture happened to show `Rdi=(nil)` and looked like it confirmed (b). It didn't: `(nil)` is exactly what a 32-bit-truncated read produces whenever the real pointer's low 32 bits happen to be zero — a coincidence that pointed the whole investigation at the wrong field for two sessions. **Proof it was the field, not the object:** this session's `GE_D255` probe read the SAME record through the *correctly*-typed `ObjectRecord.model` field (`Model*`, 8 bytes) and it was **always a valid, non-NULL pointer** — the object's model was never actually missing. **Fix (ABI-class, semantics-preserving, `#ifdef PORT`; `src/game/vtxstore.c`, `sub_GAME_7F09BAC4`):** read the pointer through `ObjectRecord.model` (the same union memory, correctly typed as `Model*`) instead of through the mistyped `ChrRecord.chrflags` alias, at both use sites in the function (the `RootNode` walk and the `modelGetNodeRwData` call). Identical bytes and identical result on N64 (both fields are 4 bytes there); correct on 64-bit PC. The earlier `GE_D255` diagnostic skip-guard (which checked the wrong field and would never have actually fired) is removed — it's no longer needed, the record's model was never really missing. **Verified live, in order:** (1) diagnostic build with the guard checking BOTH fields caught the exact moment of divergence — `ObjectRecord.model` valid, `ChrRecord.chrflags`-cast pointer producing the crash — nailing the mechanism beyond doubt; (2) the real fix (no guard, just the corrected field) held through the *entire* Facility level including multiple terminal destructions (the most consistent prior repro) and through Caverns' radio-objective terminals (the second confirmed level) with zero crashes, live on the user's own Steam Deck hardware over the ROM/assets they already had prepared. Windows rebuild + full 21-level `verify.sh sweep` also run this session as the standard regression gate. | **FIXED** — root-caused (D3x-class 32-bit pointer truncation via a mistyped enum-to-pointer cast, not a destroy-path race) and verified live on real Steam Deck hardware across both confirmed-repro levels (Facility, Caverns), zero crashes; Windows sweep clean. The separate audio-thread crash (D285) is untouched by this fix. | -| D256 | **Saves (and config) silently failed to persist on Linux whenever the game was not launched from the directory containing `data/` — reported as "saves do not work at all" on Steam Deck.** `romdataInit` finds the ROM in `$S/` (CWD `data/`) *or* `$E/` (exe dir) *or* `./`, but `sysResolvePath`'s POSIX `$S` branch (used by `ge007.eep` and `ge007.ini`) only ever produced a CWD-relative path — its "fallback" was `./data/`, identical to the primary. Launch from any other CWD (Steam non-steam-game shortcut, terminal in `~`): ROM loads via the exe-dir candidate, game runs, but every EEPROM/config write hits `fopen(..., "wb")` on a nonexistent `./data/` and fails with a stderr-only "cannot write" — saves never persist, and **every launch also starts with default settings** (F10 changes don't stick), which presents as "draw distance/LOD is low" on levels like Dam where the user had raised `Video.DrawDistance` on another machine. The Windows branch already did CWD-else-exedir; the POSIX branch now mirrors it (`readlink("/proc/self/exe")`) and creates the directory best-effort so first-run writes don't fail. **Verified on WSL:** with exe+`data/` in `/tmp/fb2` and CWD=`/`, config/eeprom/ROM all resolve into `/tmp/fb2/data/` and a 25 s run completes clean; the pre-fix binary in the same layout fails to find the ROM at all. **Caveat:** if the user's Deck launch *was* from the bundle dir (CWD had `data/`), this fix does not explain their save failure — need the save-flow detail (does the memory-card screen appear? slot confirm? "saved" message?) before closing the report. Side note found while testing: a `data/` without the generated sidecars (`pccg-*/`, `pcmodels-*/` from `tools_pc/d69_emit.py`/`d43_emit.py`) starts fine but faults in `load_bg_file` (`bg.c:865`) on level load — the reserve functions warn "stage loads will fault" and return 0; expected degraded mode, not a new bug. | FIXED (path half) — save-flow detail still owed from the user. | -| D257 | **New `Game.AllUnlocked` option (F10; default flipped OFF for v0.2.0 — see D259): skip N64 progression entirely — all 21 solo levels selectable at every difficulty, 007 mode available, and the cheat menu fully populated. Port-layer only; no game-code edits.** Three mechanisms, all in `port/`: (1) `main.c` seeds the two live `LEFTOVERDEBUG` RAM flags after `configLoad()` — `debug_enable_all_levels_flag` (all levels) and `debug_007_unlock_flag` (007 mode; both in `src/game/debugmenu_handler.c`, same class as the existing `GE_UNLOCK_ALL` getenv hook in the getter); (2) the eep shim (`libultra.c geEepromPatchAllCheats`) patches the save block at read time — special-casing `fileValidateSaves`'s exact pattern (block 4, 5×96 bytes) — setting all 20 progression-gated cheat-unlock bits per slot (`unlocked_cheats_1/2/3`; the cheat menu row on mode-select only renders when ≥1 is set, `front.c interface_menu06_modesel`) **and** filling every *empty* stage/difficulty completion-time field with the max time 0x3FF (existing player times preserved); both are then CRC'd per slot with the game's own `fileGenerateCRC` or `fileValidateSaves` would wipe the slots. (3) `optionsoverlay.c` row so users can toggle OFF for faithful progression. **Why the completion-time half is required (found by user repro):** when ANY single-player cheat is active, `g_AppendCheatSinglePlayer` makes mission-select (`get_highest_unlocked_difficulty_for_level`, front.c) accept only levels with status `STAGESTATUS_COMPLETED (3)`, not merely `UNLOCKED (1)` — AllUnlocked's debug-flag path returns 1, so enabling a cheat locked every level ("could only do Silo"). Reading the save as a fully-completed campaign satisfies both branches. Time bit-math mirrors `fileGet/SetSaveStageDifficultyTime` verbatim (10-bit fields, difficulties 0–2; 007 times are virtual). **Pitfall hit during implementation:** the first mirror of `save_data` used `times[80]` instead of `(SP_LEVEL_MAX-1)*4 = 76`, making `sizeof` 100≠96 so the block-read size check silently never matched — now enforced by a compile-time `ge_save_slot_size_check`. **Semantics:** unlocked cheats/completions persist to `ge007.eep` on any subsequent save write (self-consistent; mirrors N64 where completing a level permanently unlocks its cheat). No *active* cheats are enabled (invincibility/all-guns stay OFF); weapons remain per-mission pickups. **Verified:** fresh eep — all 5 slots validate `stored==calc` under `GE_SAVELOG=1`; user playtest: all levels selectable at each difficulty, 007 mode present, cheat menu populated, cheats toggle and work (time-modifying cheats untested by user), mission select intact with all cheats ON. | FIXED — verified by user playtest (PR #79 merged); default flipped OFF for v0.2.0 (D259). | -| D259 | **`Game.AllUnlocked` (D257) breaks audio on a fresh save: with it ON, music and SFX load at volume 0 (silence). v0.2.0 ships with `AllUnlocked` default OFF.** User-observed during v0.2.0 artifact testing ("all unlocked seems to break sound"). **Mechanism:** a fresh `ge007.eep` is zero-filled, so every save slot is all-zero. On N64 such a slot fails `fileValidateSaves`' CRC check and is rewritten as `BLANKSAVEDATA` (`src/bondconstants.h:2148`), whose `music_vol`/`sfx_vol` are `0xFF` (max). With AllUnlocked ON, `geEepromPatchAllCheats` (`port/src/libultra.c`) patches the zeroed slots (cheat bits + completion times) and recomputes a **valid** per-slot CRC, so `fileValidateSaves` accepts them as-is and never calls `fileResetSave`. The volume bytes therefore stay 0, and `fileLoadSettingsForFolder` (`src/game/file2.c:1289-1290`) loads them verbatim: `set_mTrack2Vol((save->music_vol << 7) | (save->music_vol >> 1))` = 0 → silence. With AllUnlocked OFF the zeroed slots fail CRC and reset to `BLANKSAVEDATA`, which is why sound works in the default configuration. **Disposition for v0.2.0:** flip `portAllUnlocked` default to 0 (`port/src/video.c`; `SkipIntro` was already 0) — faithful N64 progression out of the box, F10 *All unlocked* still enables the goodie. The quirk then only affects users who deliberately toggle it ON with a fresh save (recoverable: raising the in-game volume writes a nonzero slot, after which the patch leaves volumes alone). **Deferred fix candidate (port-only, ~6 lines):** in `geEepromPatchAllCheats`, detect all-zero slots and seed `music_vol`/`sfx_vol = 0xFF` before the CRC recompute, emulating what `fileResetSave` would have done; real (nonzero) saves incl. a user-muted one stay untouched. | **FIXED in v0.2.1** — the deferred fix was applied: `geEepromPatchAllCheats` now detects all-zero slots and seeds `music_vol`/`sfx_vol = 0xFF` before the CRC recompute, emulating `fileResetSave`; real saves (incl. a deliberately muted one) stay untouched. **By-ear confirmed by the user** (v0.2.1 test pass: fresh save, AllUnlocked ON — audio plays correctly). | -| D260 | **v0.2.1 (user request): mouse-wheel weapon-select direction swapped.** Wheel-up now selects the *previous* weapon and wheel-down the *next*, matching the in-game wheel menu's on-screen layout (the port had them inverted vs the user's expectation). Port-only: `inputPostWheel()` (`port/src/input.c`) — the notches>0 / notches<0 branches were swapped so scroll-up emits the back-notch and scroll-down the forward-notch. N64 build untouched; no game-code edits. | FIXED — build green; one-line branch swap, trivially reviewable. | -| D261 | **v0.2.1 (user request: "fix watch menu sensitivity for wasd/controller buttons"): holding W/S (or a fully-pressed stick axis) on the watch inventory page crawled one item per tap — no repeat.** Root cause is the interaction of two existing behaviours: keyboard W/S map to `stickY = ±STICK_MAX (0x50)` and SDL pads peg at 0x80, both *outside* the smooth-scroll band (0x1f..0x45) that D118d intentionally left for the port — so a held press only ever hit the latched single-step path (`watch_stick_y_pressed_*`, one step per press edge, no repeat). On N64 the same stick level was the *fast-scroll* band (one step per frame), which D118d removed because digital sources peg there and it became runaway scroll. **Fix (port-only, `#ifdef PORT` in `src/game/options.c`):** a bounded auto-repeat helper `geWatchStickFastStep()` — while the stick is held past the smooth band (≥ 0x46 up / ≤ −0x45 down), step one extra item every `GE_WATCH_NAV_RATE` (6) frames after an initial `GE_WATCH_NAV_DELAY` (15)-frame hold; the first press still goes through the untouched latched path, so a tap behaves exactly as before, and the smooth band + D-pad/C-button edge-repeat are unchanged. Called from `game_options_inventory_navigation()` only. **Verified:** build green; headless smoke (`GE_INPUTSCRIPT` long-W-hold on the inventory page) runs clean. Feel-check (repeat rate) owed to the user — both constants are at the top of the helper for a one-number tune. **User feel-check (v0.2.1 test pass): repeat "feels fine for now", but W/S is still too sensitive overall — desired behaviour is tactile one-press-one-item with no risk of scrolling the whole list on an over-held key; candidate tweaks (not yet done): longer `GE_WATCH_NAV_DELAY`, slower `GE_WATCH_NAV_RATE`, or gating the auto-repeat off for keyboard taps entirely (repeat only for analogue stick). Logged, no code change. | FIXED — feel-check received; W/S sensitivity follow-up logged above. | -| D262 | **v0.2.1 (user report): "3D models missing on watch menu screen item select" — the selected-item 3D preview does not appear on the watch inventory page.** User visually confirmed this session: no 3D model on the item-select page where one should be (default selection is *unarmed*, which has no model — a weapon must be scrolled to with S/DOWN). Headless repro (`GE_INPUTSCRIPT` pulse train + `GE_PCDUMP`, Dam `-level_33`): watch can't open during the intro freeze (`bondviewFrozenMoveBond` zeroes input while `g_CameraMode == CAMERAMODE_INTRO`; freeze ends ~frame 1400–1500 on Dam, and controller reads run faster than sim ticks, so scripts are timed by trial); once open + paged to INVENTORY (R_JPAD), the watch UI renders but the centre of the face is empty for every item. **Root cause found and fixed as D264** (`renderdata.flags == 0` in the watch subdraw pass — the cross-global ModelRenderData template read zeroes on PC; `subdraw()` then gated *every* geometry node, emitting exactly 1 word instead of the model's commands). Residual: with flags restored, the preview emits matrix/light-setup words (71 for item 5) but dump frames still show no visible centre geometry — a possible second layer (LOD/distance gating or fast3d rasterisation of the sub-DLs) remains unverified; user visual re-check pending. | FIXED (primary cause, D264) — pixel-level confirmation pending user run. | -| D264 | **D262's root cause (ABI/layout class, cf. D140/D52): the watch item preview's `ModelRenderData` template is read across two adjacent globals that no longer sit adjacent on PC.** `set_enviro_fog_for_items_in_solo_watch_menu()` (`src/game/gunfire.c`) starts with `ModelRenderData renderdata = *((ModelRenderData *) (&D_80035D00));` — a 64-byte copy that on N64 spans `D_80035D00` (a zeroed u32, .bss) *and* `D_80035D04[] = {1, 3, 0…}` (.data): the effective template is the one documented in the comment above `D_80035D00` in `gun.c` — `basemtx=NULL, zbufferenabled=TRUE, flags=3, rest zero` (`CULLMODE_BOTH` is 0). The PC link places .bss and .data in separate sections, so the read is all zeros: **`flags==0`**, and every geometry emitter in the subdraw node dispatch gates on `renderdata->flags & 1/2` (e.g. `modelRenderNodeDl`) — so `subdraw()` emitted exactly one word (`gSPSegment`) per preview, no matter the item. Probes this session: entry gates all pass (hand has item, model header non-NULL), node tree present (~400 nodes, isLoaded=1), world-path geometry nodes carry valid built DLs — but in the watch pass `flags=0` on every node. **Fix (`#ifdef PORT`, values identical to the N64 ROM bytes):** explicit template — `ModelRenderData renderdata = {0}; renderdata.zbufferenabled = TRUE; renderdata.flags = 3;`. Verified at Gfx level: preview emission went 1 → 71 words (item 5) / 81 (mid-scroll) / 9 (item 47, knife-class). Note for follow-up: the 71-word dump is a repeating {matrix/segment/light} unit with no `gSPDisplayList` in the first 24 words — if the user's re-check still shows no visible model, next suspects are LOD/distance gating of the local watch-space matrices (`modelUpdateDistanceRelations`, cf. 7c48f664) or fast3d handling of the preview sub-DLs (segment 3 / render modes). | FIXED — build green, probes removed; visual confirmation pending. | -| D263 | **v0.2.1 (user report): Facility — "Ourumov not shooting Trevelyan"; the scripted opening beat never triggers. RESOLVED: not a port bug — the beat is proximity/LOS-triggered exactly as on N64, and the full chain (incl. the execution shot) was verified firing end-to-end on PC.** The triage suspects (tick pacing, camera-mode gate, silent anim lookup) were all ruled out at runtime. **The beat, fully mapped** (static decode of `UsetuparkZ.c` — remember every DBYTE/TBYTE in the dump is bswap16/32'd relative to game interpretation): Trevelyan = guard chr 67 (body 9 = Trevelyan_006, pad 131) on ai_18: walks to pad 124, wanders, then loops a sees-Bond check; **only when Bond is in his vision** (range <10k, facing ±110°, fog, random gate ≈1/49/tick, LOS + *same stand tile* via `chrCanSeeBond`) does he jump to ai_19: runs at Bond, alarm + dialogue timers, sets an objective bit; BG list ai_41 (ID 0x1000, auto-started) polls that bit and spawns **Ourumov (body 7) at pad 88 with ai_23** plus a 6-soldier squad; ai_23 renumbers him to chrnum 78 and arms him → ai_22: runs to pad 123, waits for Trevelyan within 0x1400 of it, ~95 s dialogue cascade, then the **execution shot** (`HitChrWithItem` from 78 on 67). It is a multi-minute sequence that *starts* only when the player walks Bond west and down a floor into Trevelyan's room — Bond spawns 8900 units away on the upper floor with LOS blocked (probed directly: `stanTestLineUnobstructed` = obstructed, different stan tiles), identical geometry to N64. **Runtime verification** (`-level_34`, `#ifdef PORT` probes in the AI executor/vision path, all since removed): all 15 BG lists + guards start; Trevelyan alive on ai_18; every vision gate passes except the geometric ones at spawn distance; player movement confirmed working (note for future headless tests: under the port's default SOLITARE/natural-pitch scheme, walking is C-button/D-pad fed — W→C-up — and the analog stick carries pitch, so `GE_INPUTSCRIPT` SUP/SDOWN tokens do *not* walk Bond there; use UP/DOWN pulses). **Decisive test:** a temporary PORT-only teleport probe dropped Bond 65 units from Trevelyan at t≈12 s → seconds later: vision fires (chr 67 → ai_19), objective bit set, `SpawnChr body=7 pad=88` + squad, chrnum→78 on ai_23; ~2½ min later **`HitChrWithItem from_chr=78 target=67 part=8 item=6`** — Ourumov executes Trevelyan. Most likely explanation of the report: the tester never walked Bond into Trevelyan's sightline (or pre-D253 crash masked it). No game-code or port-code change required. **Kept from this session (test-harness only):** `port/src/input.c` — `GE_INPUTSCRIPT` analog-stick tokens were applied *after* the stick was already written out, so SUP/SDOWN/SLEFT/SRIGHT were silently discarded; the script override now runs before the clamp/write. | RESOLVED (not a bug), but refined (v0.2.1 further user testing, 2026-09-15) — beat verified firing end-to-end on PC incl. execution shot; **user playtest confirmed the sequence plays normally.** **Refinement: the exact trigger behavior is significantly sensitive to Bond's precise location and does not fire 1:1 identically to the N64 original across different approach paths/positions** — consistent with the beat's own documented sensitivity (range/facing/LOS/same-stand-tile + a ≈1/49-per-tick random gate, see the mapped mechanism above), so this is likely the same finicky-trigger behavior rather than a new bug, but not confirmed byte-identical to N64 for every approach. **User confirms this does NOT block level progression** either way — logged for awareness, not tracked as an open defect. Probes removed; input-script stick fix kept. **M-141: re-confirmed by user, one more mechanism now documented — the standoff has a hard TIMEOUT fallback, not just the shot-miss/objective-bit gates.** User reported (misread at first as a new freeze) reaching the Ourumov/Trevelyan standoff, waiting without shooting or triggering anything else, and after a couple of minutes Ourumov delivered his lines and executed Trevelyan on his own — **this is by design**: `ai_22`'s label `0x05` OR-gate (four early-exit conditions: two objective bits, a "Bond's shot missed" check, and a third objective bit set by an unrelated guard's surrender elsewhere in the level) is not the only path forward — falling through the whole dialogue-timer cascade (`label 0x42`'s chain of `if_local_timer_greater_than` checks) reaches `label 0x13`, which unconditionally fires `chr_hit_body_part_with_item_damage(0x43, 0x08, 0x06)` (the execution) once enough real time has elapsed, no player action required. Matches this row's own earlier "~2½ min later" measurement. **Do not re-flag "stuck standoff" as a bug without confirming the user waited the full timeout window first.** | -| D265 | **D236 investigation (port-layer, `port/fast3d/gfx_pc.cpp`): the tree cards are IA8/IA4, not IA16 — and `import_texture_ia4` decoded the RDP's I2:A2 texel as I3:A1, inverting the alpha ramp. Fixed; awaiting user visual re-test.** The earlier sessions misidentified the format: a live tri-time tile census (probe in `gfx_sp_tri1`, since removed) shows level_36's tree-card classes are (a) **IA8, line=64B → 64×16** (texdump r107), drawn OPA/bilerp/1-cycle/AC_NONE — *genuinely fully opaque* (A nibble F on 1023/1024 texels; opaque on N64 too) — and (b) **IA4, line=64B → 128×16** (texdump r117), drawn ZMODE_XLU/point/2-cycle with m2a=CLR_MEM/m2b=1MA, i.e. texel-alpha blended. There are no 32-wide IA tiles at tri time; the prior "32×32 tile" reading was wrong, and the whole earlier IA16 byte-pair/I11:A5 debate (r107) was analyzing an IA8 image as byte-pairs. **The wall's root cause:** r117 decoded as I2:A2 is a strip of ~13 discrete conifer silhouettes (trunk+canopy shapes visible in the ASCII render, `scratch/r117_ia4_alpha.png`) with a 3-level alpha ramp {0: 95% of texels, 85, 170} — faint dithered distant trees on N64. But `import_texture_ia4` read each nibble as intensity=`part>>1` (3-bit, SCALE_3_8) + alpha=`part&1`: A2=1 canopy pixels became **fully opaque**, A2=2 edge dithering became **invisible** → opaque repeating tree silhouettes = the "wall". The bug is inherited verbatim from the PD port (`pd_port/port/fast3d/gfx_pc.cpp` has the identical I3:A1 read — latent there, fatal for GE's tree strip). **Fix (applied):** `intensity = part>>2`, `alpha = part&3`, both via new `SCALE_2_8`; this is the hardware-correct RDP IA4 layout. Also cleaned up: the ia16 importer comment now states plain I8:A8 (the byte-pair read *is* correct IA16; the old "r107 proof" was misidentified data), and the earlier part-1 dimension fix stays (harmless/correct for real IA16 tiles). **Caveats/owed:** (1) user visual re-test of Surface 1 trees — headless A/B was in flight when work halted; a cross-run region diff was inconclusive (camera drift between captures); (2) the decode change affects *every* IA4 tile game-wide — regression-sweep other levels for dithered/alpha IA4 art that now renders with correct 3-level alpha; (3) if a hard repeating band remains after the fix, it is the opaque IA8 strip (a), which matches hardware and D236 needs re-scoping. **OUTCOME (user re-test): NEGATIVE — trees still render as the wall with the I2:A2 decode applied; the change was fully reverted (`git checkout` of `port/fast3d/gfx_pc.cpp`, back to the original PD-derived importers) and work is parked.** The census/RM/texture data above stands as evidence for the next attempt: the decode was *necessary* (I2:A2 is the hardware layout and r117 is unambiguously an authored tree strip under it) but *not sufficient* — remaining suspects, in order: (i) fast3d's blending of these XLU/2-cycle cards (texel alpha reaching the GL blend at all — the `texture_edge`/`SHADER_OPT_TEXTURE_EDGE` path forces `a>0.19 ? 1 : discard`, which for a 3-level ramp quantizes to opaque/discard, i.e. still hard-edged), (ii) per-card UV windowing/placement (all captured cards sampled the same u:0..64/v:0..16 window — confirm against N64), (iii) fog/distance. Note for the next session: verify what the N64 actually shows in that region before more port-side changes (the opaque IA8 strip is faithful to hardware either way). | PARKED — reverted to baseline; evidence + suspect list above. | -| D258 | **PAL/JP asset conversion is broken at the source-data level — `scripts/filelist.e.csv` and `filelist.j.csv` carry naming defects, so `gen_romassets.py e/j` (and the d43/d69/d88 emitters' `find_row`) cannot resolve PAL/JP builds. v0.2.0's drop-in ROM feature therefore ships NTSC-U only.** Discovered while scoping issue #6 (drop-in ROM). **PAL:** 31 of the 512 model rows in `filelist.e.csv` have truncated/renamed basenames (an extraction artifact — e.g. `Pbridge_console` ×6 where the resource table says `Pbridge_console1aZ…3bZ`, `Pchrgrenadelauncher` for `PchrgrenadelaunchZ`). **JP:** one font row is mislabeled — `fontBankGothic_fontchartable.bin` @3044276 is named `fontZurichBold_fontchartable.bin` (a duplicate label). Both were proven without a PAL/JP ROM: (a) greedy two-pointer sequence alignment of the 512-row `file_resource_table.inc.c` model order against each CSV's model rows gives an exact 1:1 match (481 by-name + 31 positional for PAL), offsets strictly non-decreasing, and zero size anomalies vs US (all within [0.5×, 2×]); (b) JP font row proven by the contiguity invariant — Gothic kerning @3043600+676 = 3044276 exactly hits the mislabeled row, whose size (8716) equals the US Gothic chartable, while Zurich's own chain is contiguous one row later. **Consequence:** no PAL or JP PC exe has ever been buildable from this tree (latent — only NTSC was ever exercised); the CSV `file` column is a label only (emitters look up by basename, never read the path), so the repair is a pure data fix: rename the 31 PAL model rows + 1 JP font row to the exact table symbols. **Scope decision (v0.2.0):** ship drop-in ROM support for NTSC-U only — `prepare-assets.py`/the frozen `ge007-convert` gate non-US ROMs with a clear message after SHA-1 region detection; the CSV repair + multi-region matrix + per-region exes are deferred to the Part B follow-up. | OPEN — repair path verified, not applied (out of v0.2.0 scope). | -| D284 | **`port/src/random.c`'s MIPS64 `dsll32`/`dsrl32` shift helpers were backwards (modelled as 32-bit shifts, not "shift by n+32 on the full 64-bit register"), desyncing the PC PRNG stream from the N64's from the very first draw, in every release to date (M-138 security/fidelity review; fix decided M-139b).** Fix: `dsll32(x,n) = x << (n+32)`, `dsrl32(x,n) = x >> (n+32)`, no masking — matches real MIPS64 semantics and `src/random.s`/`src/game/chrObjRandom.s` line-by-line.

The heartbeat (`portHeartbeatCheck`) then fired 3 times with a **growing** stall (8001ms → 13017ms → 18021ms, `frames=17616` unchanged all 3 times) and then stopped logging entirely, while the VI-retrace pacemaker (`D51 vi post #N`) kept incrementing at its normal ~60 Hz rate for well over 100 more real seconds until the user closed the window — i.e. the pacemaker/OS-timer side is alive, the sim/render side is genuinely wedged, not the D286 shape (which self-recovered after one dump). **Different from D286**: no explosion/level-streaming context (idle + refocus, not combat), and the growing-then-silent heartbeat pattern (vs. D286's single fire-then-recover) points at a different mechanism. **Leading lead, not yet confirmed:** at freeze time, `gfxFrameMsgQ` (`src/init.c`, the scheduler's 32-slot client completion queue, registered via `osScAddClient`) shows `valid=32/32` — completely full — while the VI-retrace queue (8-slot) is not (`valid=1/8`). A full *client* queue with the producer (scheduler) still ticking implies the **consumer** (the main thread's `osRecvMesg(&gfxFrameMsgQ, ...)` in the frame loop) stopped draining it — consistent with the main/render thread blocking on something else (a lock, a GL call, a Windows message-pump stall) during or after a long-idle refocus, not with the scheduler itself stalling. Not yet identified what that something is. A pre-existing, currently-unused diagnostic (`GE_D60`, `port/src/libultra.c:630+`) already watches `gfxFrameMsgQ` receives and looks like the right next probe to enable. **Next, concrete:** reproduce with `GE_D60=1` (and ideally `GE_INPUTLOG=1`) running under `debug.ps1`, leave the window idle+unfocused 15-20 min, refocus, and once frozen `bt full` the actual game/render thread (not just the auto-dump's generic `WaitForMultipleObjects` frames for `shedThread`/`audioThread`) to find what it's blocked on. Cross-ref D134's superficially-similar-sounding-but-different mechanism (a different, 8-slot queue, already fixed) — do not assume the same fix applies here without confirming the actual blocked call site. | OPEN — one confirmed occurrence, real (not self-recovering), not root-caused; `gfxFrameMsgQ` full is a lead, not a confirmed cause. | -| D288 | **Silo intro: a huge, flat-shaded, untextured brown/tan triangle sweeps across the frame during the camera pan down the missile shaft (M-141, user report — "weird triangle drawn on silo intro randomly when the camera pans around the rocket"; previously catalogued as `GRAPHICS-BACKLOG.md` D171, "observed, not investigated" since M-34, never given a full findings.md entry until now).** Reproduced headlessly this session: `GE_PCDUMP=1-2000:10 ./build-pc/ge007.x86_64.exe -level_20` (run backgrounded, not foregrounded — see the environment note below), captured to `./ppm/`. Visual sweep (contact-sheet montages, `docs/img/bugs/D288-silo-stray-triangle-sheet.png` covers frames 571-751; `-closeup.png` is a full-res crop of frame 691) shows: **clean at frames 481-561** (no triangle), **first appears between frame ~562-601**, grows continuously in screen size through frame ~711 (by which point it covers roughly a third of the frame), then **shrinks and is gone by ~731-741** as the scene cuts to the first-person shaft-corridor view. Sampled pixel color is **exactly uniform** across the whole triangle (`RGB(83,62,44)` / `#533E2C` at two different sample points) — no gradient, no texture detail — i.e. this is a flat-shaded (no per-vertex color variance, no texture bound) single triangle, not garbage/noisy vertex-color data. **Reading of the evidence:** the grow-then-shrink-then-vanish arc across ~15 real seconds of camera motion is the classic signature of a genuine 3D triangle in world space that the camera flies close to/through during the scripted pan — not a 2D HUD/UI element (which would stay roughly fixed in screen size) and not obviously a `D146`-class freed-memory read (which reads as noisy garbage bytes, not a clean uniform flat color). The flat uniform color argues this is a REAL, correctly-colored asset triangle whose position/transform is wrong, which points at the same neighborhood as D106/D233 (near-plane / w-clip mishandling in `port/fast3d/gfx_pc.cpp`) rather than a game-code or converter data bug — but this is a read of the visual evidence, not a code-level confirmation; no probe has been run yet. **Not yet identified:** which model/prop this triangle belongs to (nothing in `UsetupsiloZ.c` was grepped for a matching solid-brown material this session), and no `port/fast3d/` tracing was done to catch the actual triangle at draw time. **Environment note (new, useful beyond this bug):** launching `ge007.x86_64.exe` in the **foreground** under this session's Bash tool with `timeout N ...` produced **zero** `ppm/` output despite `GE_PCDUMP` being set and verified exported — the `ppm/` directory was never even created (`GE_MKDIR` never ran or `frames`-gated capture never fired). Backgrounding the same invocation (`... &`, `sleep N`, `kill`) worked immediately and reliably. Not root-caused (didn't block this investigation), but worth remembering for the next session that needs `GE_PCDUMP` from this same tool. **Next, concrete:** (1) grep `assets/obseg/setup/UsetupsiloZ.c` / the missile-shaft model's material table for a solid `RGB(83,62,44)`-ish prim/vertex color to identify the source asset; (2) add a temporary `#ifdef PORT` probe in `gfx_sp_tri1` logging any triangle whose post-transform screen-space bounding box exceeds some fraction of the viewport together with each vertex's `w`, gated to `-level_20` frames ~560-740, to catch the culprit triangle's `w` sign/magnitude at the moment it blows up — same style as the existing `GE_D271`/`GE_D104` probes; (3) cross-check against D233's `w<0` trivial-reject fix and D106/D271's near-plane portal-bound clamp to see if this is a third site with the same underlying class of bug, or a genuinely new mechanism. | OPEN — visually confirmed and precisely bounded (frames ~562-741 of a bare `-level_20` boot), root cause not yet identified; promoted from the long-parked `GRAPHICS-BACKLOG.md` D171 entry with real evidence. | -| D289 | **Dam: a crash in the computer room, not reproducible on a second attempt (M-141, Steam Deck user playtest).** **User's own read, most likely: the same computer-terminal SIGSEGV as D255** (Facility door-opening terminals — root-caused and FIXED this session, M-141, `vtxstore_fix_refs` reading `Model*` through the wrong union field, a 32-bit pointer truncation). D255's mechanism is generic to computer-terminal props, not Facility-specific, so a Dam terminal hitting the same bug is plausible and would already be fixed by the same patch. **Not yet confirmed** which build the user was on when this happened (pre- or post-D255-fix) — if it was pre-fix, this is very likely just D255 and needs no separate investigation; if it recurs on a build that has the D255 fix, that's a new, real, distinct bug worth its own crash log. | OPEN — needs a human re-test specifically on a build with the D255 fix (this session's `release/v0.3.0`, not any earlier build) to see if it still happens. If it does, get `ge007.crash.log` (or a gdb `bt full` under `debug.ps1`) and the exact terminal/action — that's the actionable next step, not further static analysis. | -| D290 | **Watch's in-game "controller" section shows no control-pad graphic (M-141, Steam Deck user playtest).** Likely a missing/failed texture or model bind on one of the watch's equipment-display pages — candidate area `src/game/bondview2.c` (watch display) alongside the front-end options/controller-config screens, not yet located precisely. | OPEN — observed, not investigated. Needs a live repro (open the watch, navigate to the controller-config page) plus a screenshot for comparison against N64 reference. | -| D291 | **Dam: texture glitches when the truck drives past (M-141, Steam Deck user playtest).** No further detail captured (which surface/texture, timing, one-shot vs. every pass). Could be a moving-vehicle-specific instance of a known texture-cache/TMEM-residency class (cf. D124's stale-DL-marker mechanism, a different object family) or something new. | OPEN — observed, not investigated. Needs a live repro with the truck's exact position/timing and, ideally, a screenshot. | -| D292 | **Death animations are glitched — Bond is often sunk halfway into the floor (M-141, Steam Deck user playtest).** **User confirms this is the same broader "Bond's world model is positioned wrong" problem as D173** — not a new/separate mechanism, another surface of the same known-but-under-investigated bug. The umbrella is already tracked: `GRAPHICS-BACKLOG.md` D148 is explicitly "the tracking entry for the whole cutscene-reliability problem," already lists D173 (floating at level start / Cuba credits) and a Cradle instance ("Bond spins in circles" during the Trevelyan-falls cutscene) under it — findings.md's D173 entry has the fullest investigation detail (M-106's two ruled-out D209-style struct-aliasing candidates, LOW-MEDIUM confidence that class is even the right one). Nothing has actually been lost — the write-up just isn't concentrated in one place (split across `GRAPHICS-BACKLOG.md` D148/D173 and `findings.md` D173), which reads as "known but not detailed" unless you go looking. Sunk-into-floor is a third concrete instance of the family (level-start floating, cutscene spin, now death-pose sinking) — worth keeping as one thread when it's next investigated live, since a single root cause (most likely the render-side puppet/joint transform, not collision) could explain all three. | OPEN — same status as D173 (observed, not root-caused). Cross-ref D173/D148 as one investigation thread, not three separate bugs, next time someone has a live session to chase it. | -| D293 | **QoL ask: no discoverable way to quit the game from the UI (M-141, Steam Deck user playtest — "couldn't see a way to exit the game. Maybe build this into the settings/options menu.").** Confirmed in code: the only quit path is `SDL_QUIT` (`port/src/video.c:515`, the OS window-close event / Alt+F4) — there is no Escape-key handler and no "Quit" entry in the front-end menus or the F10 options overlay. Fine on a desktop with visible window chrome; a real gap on Steam Deck / controller-only / fullscreen setups with no easy way to reach the OS window controls. | OPEN — not investigated, low complexity. Candidate fix: a "Quit to Desktop" row in the F10 overlay (`port/src/optionsoverlay.c`) and/or an Escape-key binding in the front-end menu context (`port/src/input.c`), calling the same path `SDL_QUIT` already triggers. Cheap, port-only, good QoL-batch candidate. | -| D294 | **Statue: ground geometry near the large CCCP/hammer-and-sickle monument briefly renders solid black over a wide area, then self-recovers 10-30 seconds later (M-141, Steam Deck user playtest).** **Correction (user, same session): happened at normal ground level during normal forward progression through the level, near the statue/monument — NOT from the elevated ramp vantage point** (the ramp is a nearby landmark used to describe the location, not the trigger condition; a first-pass write-up of this report wrongly framed "wide visibility from elevation" as the likely cause — that framing is retracted). User's settings: max `Video.DrawDistance`/`Video.LodDistance`, high `Video.FovScale` (~130%). **Not an exact match for any existing tracked culling bug, but closely neighbors three:** D222 (high-FovScale culling breakage — but D222 is specifically *NPC/object* culling near screen edges, root-caused and FIXED, not ground/BG geometry); D249 (LOD/culling breakdown on large open levels — but D249 is at *default* FOV on Streets/Egyptian, and doesn't self-recover); D218 (wide-FOV fog/far-clip boundary artifacting — but D218 is a color/tint issue at the frustum edge, not geometry going missing). **Distinguishing features that don't match any of the three:** (a) the drop-out is transient and self-corrects without the player doing anything special, (b) it's ground/BG geometry specifically, not NPCs or props, (c) it happens *within* the draw-distance/FOV settings, not past a boundary. Leading unconfirmed guess, weakened by the correction above but not ruled out: a portal/room-visibility computation (the BFS the D106/D271/D233/D234 family already touches) temporarily excluding a room/cell that contains ground geometry until the walk recomputes on subsequent player movement — the widened-FOV-frustum framing no longer applies (the drop-out wasn't tied to an unusually wide sightline), but a room-transition/streaming-timing trigger at ground level is still plausible and fits the self-recovering, "normal progression" description just as well. This is a hypothesis from the symptom shape, not a code-level finding, and now has less to go on than the first write-up assumed. | OPEN — not investigated. Next: reproduce on Statue (`-level_22`) at the reported settings (`Video.FovScale≈130`, max draw distance/LOD) near the ramp by the CCCP monument; a `GE_D271`/`GE_D104`-style room-visibility trace (`roomsDrawn` count, portal-cull hits) correlated with the black-ground window would confirm or rule out the room-visibility-BFS hypothesis quickly. | +| D256 | **Saves (and config) silently failed to persist on Linux whenever the game was not launched from the directory containing `data/` — reported as "saves do not…** — full `## D256` entry at file tail | FIXED (path half) — save-flow detail still owed from the user. | +| D257 | **New `Game.AllUnlocked` option (F10; default flipped OFF for v0.2.0 — see D259): skip N64 progression entirely — all 21 solo levels selectable at every…** — full `## D257` entry at file tail | FIXED — verified by user playtest (PR #79 merged); default flipped OFF for v0.2.0 (D259). | +| D259 | **`Game.AllUnlocked` (D257) breaks audio on a fresh save: with it ON, music and SFX load at volume 0 (silence). v0.2.0 ships with `AllUnlocked` default OFF.** — full `## D259` entry at file tail | **FIXED in v0.2.1** —… | +| D260 | **v0.2.1 (user request): mouse-wheel weapon-select direction swapped.** — full `## D260` entry at file tail | FIXED — build green; one-line branch swap, trivially reviewable. | +| D261 | **v0.2.1 (user request: "fix watch menu sensitivity for wasd/controller buttons"): holding W/S (or a fully-pressed stick axis) on the watch inventory page…** — full `## D261` entry at file tail | FIXED — feel-check received; W/S sensitivity follow-up logged above. | +| D262 | **v0.2.1 (user report): "3D models missing on watch menu screen item select" — the selected-item 3D preview does not appear on the watch inventory page.** — full `## D262` entry at file tail | FIXED (primary cause, D264) — pixel-level confirmation pending user run. | +| D264 | **D262's root cause (ABI/layout class, cf.

So the *transition* works; only the scripted cutscene step is skipped or silently fails. Static trace: Dam's end sequence is `UsetupdamZ` ailist `ai_24` (id 0x1004, gated `if_bond_in_room_with_pad(0x4a01)` — Bond reaches the exit) → lock controls, `bond_set_locked_velocity` (auto-walk off edge), wait `if_bond_y_pos_less_than` (Bond falling) → fade → `if_objective_all_completed` branch → `camera_switch`/`jump_to_ai_list` into the abseil ailist `ai_17` (id 0x0412: `screen_fade_from_black`, `music_xtrack_play`, `guard_play_animation(0xb100…)` = rappel anim on a puppet chr, three `camera_switch` w/ fades, `exit_level`). `camera_switch(TAG,…)` resolves a `CutsceneRecord` (propDef type 46, records 322/324/326 paired with Tags 10/11/12) via `tagGetCommandIndex` + `setupGetPtrToCommandByIndex` (a **command-index count walk over the propDef stream** using `sizepropdef()`). CutsceneRecord itself is all-scalar 28 B, correctly converted (`d88_propdefs.py` 46→28). **Leading hypotheses, unverified:** (a) the index-count walk desyncs because some earlier propDef type Dam emits (Vehicle 321 — D122 "medium confidence" tail; TintedGlass) has a wrong PC `sizepropdef` stride → `camera_switch` gets a bogus `cdef`/`TagIndex<0` → cutscene silently skipped, `ai_17` falls through to `exit_level`; (b) the trigger chr for `ai_24`/`ai_25` isn't spawned / `if_bond_in_room_with_pad` never true and the level ends via a different path; (c) D75/anim-model family — the puppet `guard_play_animation` rappel anim doesn't render (third-person Bond model absent, like the gun-barrel/cast models) so the cutscene "plays" invisibly but the user perceives it as skipped (less likely — user reports an instant cut, not a blank pause). + +**Status (from §F table):** DIAGNOSTIC SHIPPED, not root-caused (`c95713f5`, `#ifdef PORT` + `GE_D160=1`): trace points in `bossReturnTitleStage` (entry + caller), `bondviewSetCameraMode` (mode/stage/`g_IntroSwirl`/intro-anim-idx/caller), and AI cmds `EndLevel`/`exit_level`, `CameraLookAtBondFromPad`, `CameraSwitch` (prints `cdef` ptr / `TagIndex<0` / tag `NOT FOUND`). **Next step:** user plays Dam to the exit with `GE_D160=1` (via `debug.ps1`); the trace answers (1) does `CameraSwitch`/`CameraLookAtBondFromPad` execute at all → trigger fires? (2) if yes, is `cdef` a sane pointer → propDef-walk / converter bug (a), same family as D122/D132/D157; (3) if the cam cmds never run → ai_24 trigger / chr-spawn bug (b). If it's (c), `bondviewSetCameraMode` shows POSEND being set + control returns normally. This is likely a WRITE-UP-then-fix (propDef stride) rather than a hack. Confidence in hypothesis (a): medium. **M-106 static re-audit (no build/runtime access this session — see note below): hypothesis (a) independently RE-CONFIRMED RULED OUT.** `CutsceneRecord` (`src/bondtypes.h:3785-3792`, propDef type 46) is **all-scalar** — `PropDefHeaderRecord` (4B header) + `coord3d pos` (12B, 3×f32) + `theta`/`verta`/`pad` (4B each) = 28B exactly, zero pointer/union fields, so it cannot exhibit the D122/D126/D132/D209 pointer-width-growth pattern at all (nothing to widen); this matches `porting-notes.md`'s already-recorded M-31 conclusion (`§ "D160 — a propDef command-index walk desync..."`) that the stride cross-check is clean for all 48 types. Traced the `AI_CameraSwitch` path end-to-end (`chrai.c:3990-4013`): `tagGetCommandIndex`/`setupGetPtrToCommandByIndex` resolve `cdef`, then `gBondViewCutscene = cdef` and `bondviewSetCameraMode(CAMERAMODE_POSEND)`; the render side (`bondview2.c:1558-1590`) reads `gBondViewCutscene->pad`/`pos`/`theta`/`verta` directly off that pointer with no intermediate copy/struct-punning step that could introduce a *new* aliasing bug — this leg of the pipeline is clean. **Did not get far on hypotheses (b)/(c)** (AI trigger-fire vs invisible-puppet-render) — no interactive session / no build toolchain available in this worktree (`gcc`/`cmake` not on `PATH`; MSYS2 MINGW64 environment not active), so the `GE_D160=1` Dam-to-exit playthrough this row has needed since M-31 still has not been driven. **Confidence update: hypothesis (a) — HIGH (ruled out, independently re-derived, not just cited); (b)/(c) — unchanged, still need the live trace.** No code changes made (nothing to fix once (a) is ruled out); this is a documentation-only confirmation pass. See also D173 below — if the Cradle "Bond floating/spinning" symptom filed under this label is the puppet-render family (D75/D156), closing D173 first may explain the residual `#4 GOTO` here too. **M-107 — the live trace finally happened; (b)/(c) both REFUTED, real root cause moved to D243.** `GE_D160=1` on `-level_33` (Dam) plus a fresh-save normal playthrough all show the AI trigger firing and all three `camera_switch` commands executing (`bondviewSetCameraMode(7)` × 2-3, then `bossReturnTitleStage`) — the cutscene is NOT skipped and the puppet is NOT invisible; it renders, but corrupted (violent camera-shake artifact during each angle cut). Root-caused no further than "stale/freed display-list memory read, likely a render-pipeline race" — full writeup and evidence under **D243**, which now owns this bug going forward.

Root-caused with a `GE_TEXDUMP` PPM+param dump (`gfx_opengl.cpp` / `gfx_pc.cpp`): the offending surface is **one texture, `fmt=CI siz=8b, 16×16`**, uploaded with **`rdp.palette_fmt == G_TT_NONE` (0)** while every other CI texture that frame has `palfmt=0x8000` (`G_TT_RGBA16`). GE draws the Depot roof with the TLUT **disabled** (`gsDPSetTextureLUT(G_TT_NONE)` — a legit N64 idiom: a CI-siz tile with no LUT feeds the raw 8-bit TMEM texel straight into the colour pipe, i.e. it behaves as a plain **I8** texture). fast3d's `import_texture()` ignored `palette_fmt` and always did the palette lookup for `fmt==CI`, indexing a **stale `rdp.palette`** left over from a previous texture → the 16×16 image came out as pure blue/cyan/magenta noise; the "radial rays" were that high-frequency noise aliasing on the steeply-receding ceiling plane (which is also why filtering couldn't help — the data was garbage). Fix: in `import_texture()`, `fmt_eff = (fmt==G_IM_FMT_CI && rdp.palette_fmt==G_TT_NONE) ? G_IM_FMT_I : fmt`, and dispatch on `fmt_eff` (CI4→I4, CI8→I8). Narrow — only changes surfaces that are currently 100% garbage. Verified: Depot corridor + control-room ceilings render as clean dark/grey industrial roofs; `-level_09`/`-level_30`/`-level_34` sweep PASS, unregressed. `GE_TEXDUMP` (env-gated PPM dump of every uploaded texture + a `fmt/siz/palfmt/palidx` log line) kept as an inert diagnostic. Confidence: **high** (before/after screenshots + the palfmt=0 evidence). + +**Status (from §F table):** FIXED (`port/fast3d/gfx_pc.cpp` `import_texture`, `port/fast3d/gfx_opengl.cpp` diag). porting-notes.md §D. + +## D152 — Mission-failed / objective-failed → permanent black screen (M-28, user bug report — LIVE process inspected, not yet fixed). + +**Mission-failed / objective-failed → permanent black screen (M-28, user bug report — LIVE process inspected, not yet fixed).** User killed Trevelyan in Facility (Ctrl = fire, no crouch bind) → failed the objective → screen faded to black and never came back; process stayed alive under `debug.ps1`. `gdb.txt` (kept running): rendering stops dead at frame 12600 (`frames=12657` frozen across 206 heartbeat dumps / ~7 real min), VI pacemaker still posts. **Deadlock on `s_imLock`** — the D147 recursive-mutex that backs `osSetIntMask`. Both consumer threads are blocked in `pthread_mutex_lock(&s_imLock)` and neither owns it: `mainThread` = `sndSetScalerApplyVolumeAllSfxSlot` → `sndApplyVolumeAllSfxSlot` → `sndSetSfxSlotVolume` → `alEvtqPostEvent` (`event.c:82`) → `osSetIntMask(OS_IM_NONE)` (`libultra.c:1232`); `amMain`/audioThread = `amHandleFrameMessage` → `alAudioFrame` → `sndPlayerVoiceHandler` → `alEvtqNextEvent` (`event.c:47`) → `osSetIntMask(OS_IM_NONE)`. `sndSetScalerApplyVolumeAllSfxSlot` is the **mission-failed audio fade-out** (ramps `g_sndSfxVolumeScale` → 0 each frame, `AL_SNDP_RELEASE_EVT` posted per active `ALSoundState` per frame) — so the fade-to-black *is* the intended fail transition, and it hammers the event queue hard enough that the `osSetIntMask` lock is left owned by a party not in the 3-thread dump (a leaked unbalanced `OS_IM_NONE` — libaudio has early-return mask paths — or a transient thread that acquired it and exited; `gdb.txt` shows `New Thread`/`exited` churn every few k frames). D147's "the decomp never blocks while holding OS_IM_NONE → cannot deadlock" assumption is **falsified** by this path. Same family as D147 / porting-notes.md §D4. + +**Status (from §F table):** MITIGATED (`port/src/libultra.c`, M-28, `#ifdef PORT`/port-only). `osSetIntMask` is now a **self-healing** logical lock: `OS_IM_NONE`/`OS_IM_ALL` acquire/release a process-wide recursive critical section tracked by `s_imHeld`/`s_imOwner`/`s_imDepth` under a short bookkeeping mutex `s_imMx` + condvar. Normal (balanced, microsecond) audio critical sections behave exactly as the D147 recursive mutex did. A waiter that blocks **> 2 s** (`OS_IM_STUCK_NS`) concludes the holder leaked it, logs `LOG_ERROR` with the stale `s_imOwner` + the stealing caller's return address, and **steals** the section — so a leaked/unbalanced `OS_IM_NONE` (or an acquire-and-exit transient thread) can no longer wedge the game forever; worst case is a ~2 s audio hiccup + a log line naming the leak. Builds clean. Still OPEN: the exact leaking call site (find it from the `D152: ... stealing from owner=` log next time it fires) and the proper narrow fix (dedicated `ALEventQueue` lock, or restore-on-thread-exit). Regression check deferred — `-level_09`/`-level_20` both flaky under the current machine load (D117/D134), and clean `master` itself has a separate nondeterministic `-level_09` frame ~900-1400 `0xc0000005` (see below). + +## D154 — `bg.c` room-geometry ray/hit-test GBI parser port (M-28, WRITTEN / UNVERIFIED / UNCOMMITTED). + +**`bg.c` room-geometry ray/hit-test GBI parser port (M-28, WRITTEN / UNVERIFIED / UNCOMMITTED).** `bgTestRayIntersectionInRoom` (`bg.c:3331`, called by `bgTestBulletHitBackground` on every shot that resolves against background geometry) is the D135 sibling flagged since M-23: raw `((u8*)gdl)[k]` / `((u32*)gdl)[i]` byte/word indexing into what is now the 16-byte PC `Gfx` room DL (D85 `bgWidenRoomGdl` + `texLoadFromGdl`) → desync → OOB `vtxbase[idx]` / walk-off AV the first time you shoot a wall or floor. Ported `#ifdef PORT` (N64 verbatim under `#else`): `vtxoff`/`vtxbase`/`op` via the `.dma` view (matches the already-ported `bgBuildRoomVtxBounds`); G_TRI1 indices from `(w1>>16/8/0)&0xff /10`; the 12 G_TRI4 nibble extractions from `(u32)gdl->words.w0/.w1` (each mapped from the N64 byte/halfword layout — table in the code comment, cross-checked twice); both `texturenum` recoveries → `-1` (the KSEG0 `*(u16*)(w1-8)` deref is invalid for the port's converted GDLs, same as D135; texnum only picks the impact decal/sound, parked D77). Builds clean. **Verification blocked** — a no-input `GE_PCDUMP` capture never fires a bullet so it never calls this function; needs a real firefight into a wall on an idle machine (this session's box was thrashed → D153/driver crash on every run). + +**Status (from §F table):** **M-30 re-audit + fixes (still playtest-gated for final verify).** Cross-checked the ported G_TRI1 + all 12 G_TRI4 nibble recoveries twice against the N64 `#else` and the raw BE-word bit derivation — **G_TRI1 and G_TRI4 are correct**. **Two bugs fixed:** (1) `vtxoff` — the port read `gdl->dma.par & 0xf`, but the PC `Gdma_le` shim (`port/shim/PR/gbi.h`) maps `.par` to bits 0-23 of word0 (the packed *length*, always 16-aligned) not the N64 byte-1 params field at bits 16-23, so vtxoff was silently forced to 0 (breaks any G_VTX batch with `v0 != 0`, i.e. multi-batch rooms → wrong `vtxbase[idx]` → OOB). Now `((u32)gdl->words.w0 >> 16) & 0xf`. (2) **Sibling ported** — `bgTestBulletHitBackground` tail (`bg.c:~3841`, the post-hit G_SETTILE back-scan for `tileformat`/`tilesize`) was itself an unported raw `((u8*)gdl)[0]`/`[1]` + 64-bit `words.w0 << 11 >> 30` parser over the same widened DL; wrapped `#ifdef PORT` (opcode from bits 24-31, byte1 from bits 16-23, `(u32)`-forced 32-bit width for the tilesize shift). **Diagnostic:** `GE_D154=1` → `osSyncPrintf` of the parsed cmd/vtx-index stream (call header + per-TRI1/TRI4 `idx`) for the first 64 invocations, for the user/integrator to eyeball. Build green (`ntsc-final`, 242/242). Runtime unverifiable in a worktree (no `data/`); still needs a firefight-into-wall on an idle machine + `-level_09` framediff.

Root: the `while (1)` at `model.c:3131` in `modelSetAnimFrame2WithChrStuff` steps the root-motion accumulation one anim frame at a time from `framea` (`model->animframe1`) to `frameb` (`frame`, accumulated in `modelTickAnim` as `frame += playspeed * speed` per tick). If `frameb` arrives **NaN or blown up** — a cutscene anim whose blend/transition math produces a huge/non-finite `model->speed`/`playspeed`/`timespeed` (`model.c:3436` `/ model->unkb0`, `:3477` `/ model->timespeed`, both guarded `> 0` but not against tiny values) — then `floorFloatToInt(frameb)` yields garbage, `endframe - curframe` ≈ 2^31, and the loop (each iteration: `sub_GAME_7F06D3F4` joint transform + `cosf`/`sinf` + `modelConstrainOrWrapAnimFrame`) runs effectively forever. **Likely deeper cause (unconfirmed, needs the repro):** these speed/blend fields are `Model` struct members; if this model is punned/inline (D100/D140 family) and `sizeof(Model)` growth misaligned them, they read garbage exactly when a cutscene sets an unusual anim transition. + +**Status (from §F table):** GUARDED (`src/game/model.c`, `#ifdef PORT`): (1) in `modelSetAnimFrame2WithChrStuff`, if `frameb` is non-finite or `|frameb| >= 1e6` snap it to `framea` (loop then does ~0 iterations; the `modelConstrainOrWrapAnimFrame` at :3211 still clamps `model->frameb` to a valid frame); (2) in `modelTickAnim` after the tick loop, if `frame`/`frame2` went non-finite/absurd fall back to the pre-loop `model->animframe1`/`animframe2` so the NaN can't poison model state every frame. `!(x > -1e6f && x < 1e6f)` catches NaN too. Anim frames are 0..few-hundred so 1e6 is a safe ceiling. Verified: build green; `-level_09` frame 200 unregressed (guards never fire in normal play). **User to re-verify the Facility outro.** If it still hangs, the NaN source is upstream — dump `model->speed/playspeed/timespeed/unkb0` in `modelTickAnim` during the cutscene. porting-notes.md §E. + +## D155 — Facility outro-cutscene end → "hang" = unclamped `deltaFrames` spiral (M-29, user bug report). + +**Facility outro-cutscene end → "hang" = unclamped `deltaFrames` spiral (M-29, user bug report).** User watched the Facility outro cutscene; at the end the game froze (process alive, kernel-heartbeat dumps). Symbolicated `mainThread` stack from the port's own hang dump: `modelConstrainOrWrapAnimFrame` ← `modelTickAnim` ← `chrUpdateAnim` ← `chrTick` ← `playerTick` ← `propsTick` ← `lvlRender`, sampled there across *every* heartbeat dump. Root cause: `waitForNextFrame()` (`src/game/frametiming.c`) sets `nextFrameTime = (osGetCount() − prev + 387937) / 775875` and passes it **unclamped** to `updateFrameCounters` as `deltaFrames`. `osGetCount()` is wall-clock on the port (D117), not VI-locked, so a real-time stall — the asset load at the cutscene→debrief boundary, made far worse by the user running a local LLM on the same box — makes `nextFrameTime` balloon to hundreds/thousands. That becomes `speedgraphframes` → `g_ClockTimer`, which drives `modelTickAnim(model, g_ClockTimer, 1)`'s `while (numticks-- > 0)` loop once per character per render, plus dozens of `for (i = 0; i < g_ClockTimer; i++)` sim loops (`bondhead.c`, `bondview2.c`, `explosion.c`, `options.c`…). One render then does thousands of anim ticks × N characters → multi-second frame → heartbeat trips, and the slow frame feeds an even bigger delta next time → unrecoverable spiral.

This is a **linker-adjacency assumption**: on N64 `.data` the two file-scope globals are emitted in source order so `&legalscreen_MRD == legalpage_text_array + 12` and the loop count is exactly the array length. mingw/GCC reorders them — in `build-pc/ge007.x86_64.exe` `legalscreen_MRD` links at `0x1401305e0`, **0x60 bytes before** `legalpage_text_array` at `0x140130640` (verified via `nm`).

The other 11 legal lines never render.

Root-caused with `GE_DTEX`: the photo is a **65×65 I4** (also seen: 65×65 I8, 95×32 IA8) with a full mip chain; `import_texture_i4` uploads it `line_size_bytes*2` (= padded stride) wide and `size_bytes/line` tall — geometry fine. The comb is **`texSwapAltRowBytes` (`src/game/image.c:2191`)**: it pre-swaps every **odd** texture row in 8-byte (one-`u32`) groups to compensate for the N64 RDP's odd-line TMEM address XOR (bit 2) during 4-byte-word `gDPLoadBlock` loads. fast3d does **not** emulate that XOR (no odd-row handling anywhere in `gfx_pc.cpp`), so the pre-swapped odd rows stay scrambled in the uploaded GL image. It's called on *every* level of *every* texture on *every* path (§4), but only bites where the texture is large enough and viewed 1:1 to see the 8-texel comb — glaring on the ~big front-end photos, ~invisible on small HUD glyphs / distant in-level surfaces (which is why it was written off as "front-end model" work for many sessions).

Velocity-in → velocity² cursor. **Fix (port-only, no `front.c` edit):** `input.c` now runs a P-controller — it keeps its own estimate `menuEst{H,V}` of where the game cursor is, integrated each poll with the *exact same recurrence* as `frontUpdateControlStickPosition` (`menuCursorStep()`), accumulates a `menuTgt{H,V}` target from raw mouse motion (clamped to the same rect), and emits `stick = clamp(MENU_P_GAIN·(target−est), ±70)`. `MENU_P_GAIN = 6.0` → per-poll error decay ≈ 0.45 (`0.075·6`), so no overshoot and ~8-poll settle; stick falls under the game's ±5 deadzone within ~1px of target so the cursor parks with zero jitter/drift. The estimate re-syncs to the true cursor whenever the target is held at a screen edge (both clamp). `Input.MenuPointerSpeed` scales the mouse→target mapping (bump toward 150–200 if the sweep feels short — `est` steps once per controller poll ≈ 2×/rendered-frame vs `front.c`'s 1×/frame, a rate mismatch absorbed by this knob). `Input.MenuPointerMode` (0 = old velocity, 1 = pointer, **default 1**) is the escape hatch. `GE_INPUTLOG` prints an `menuptr est=/tgt=/eff=/stick=` trace line for tuning. With no mouse motion `target==est==centre` → `eff=0` → emitted stick unchanged → prior behaviour exactly. + +**Status (from §F table):** FIXED (`port/src/input.c`; `Input.MenuPointerMode`, `Input.HipfirePitchSpeed` added).

Fast mouse → `duty≈1` → C-button every poll (solid hold, as before); slow mouse → sparse taps proportional to speed. `HIP_PITCH_FULL = 6.0` px/poll for a solid hold; `Input.HipfirePitchSpeed` (10–500, default 100) tunes it. Aim-mode (RMB, already fully analog) untouched. No mouse motion → no pulse → prior behaviour. + +**Status (from §F table):** FIXED (`port/src/input.c`). SMALL-FIXES B7. **M-87: likely SUPERSEDABLE — see the "SOLITAIRE natural-pitch" note below.** This pulse hack was necessary because the port forces a control scheme (HONEY, the 1.1 default) whose hipfire pitch is digital-only. GE's own **SOLITAIRE (1.2) / GOODNIGHT (1.4)** schemes don't have that constraint at all (see D194) — under those, the *entire* primary analog stick is free for continuous, unclamped pitch+yaw ("natural pitch/turn"), because movement is redirected onto digital C-buttons instead. If the port switches its forced `controldef` to SOLITAIRE/GOODNIGHT (also the right move for D223's wheel-cycling design and D194's mouse-feel ask), this whole digital-pulse emulation becomes unnecessary — mouse-Y would drive the stick's Y axis directly and continuously, same as X already does, with **zero digital-button emulation for pitch at all**. Don't remove D166's code without first confirming the scheme switch; keep as a fallback for whichever legacy path still needs it. + +## D169 — Front-end mouse pointer can't reach the outer cells of the mission/level-select grid — only an inner ~3×3 selectable (M-33, developer bug report). + +**Front-end mouse pointer can't reach the outer cells of the mission/level-select grid — only an inner ~3×3 selectable (M-33, developer bug report).** The D165 pointer P-controller in `port/src/input.c` is hard-coded to a **320×240** virtual field (`MENU_CURSOR_HI_H`/`_HI_V` = 300/220, `MENU_CURSOR_MID_H`/`_MID_V` = 160/120, `input.c:145-149`), but GE's front end runs at **440×330** (`front.c:8570` `viSetViewSize(440,330)`; default cursor home 220/165 `front.c:285`). `frontUpdateControlStickPosition` clamps the real cursor to `[20,420]×[20,310]` (`front.c:1195-1217`); the mission-select hit-test grid spans x 73…352 / y 62…270 with outer split points 317 / 235.5 (`front.c:516,519,3180,3194`). The port clamps its pointer *target* and *estimate* to 300/220 (`input.c:553-564`) → the stick zeroes out once both saturate → the game's `cursor_h_pos`/`cursor_v_pos` park at ≈300/220, short of the two outer columns and the bottom row. File-select / mode-select / main-menu are unaffected because their hit targets (centred folder boxes, the `x=126` mode list, the `x=106` difficulty list) all sit inside the 320×240 sub-box. Not the D118d `joyGetStickY`-threshold class — this is a virtual-resolution constant mismatch, closer to D164 (a front-end layout constant wrong on the PC path). Also note: the "re-syncs whenever the target is held at a screen edge" comment at `input.c:141-143` describes behaviour the code doesn't implement — the only estimator reset is the activation re-home (`input.c:545-549`), so once pinned at the clamp the estimate never recovers.

The estimator seed on activation is now the real `cursor_h_pos`/`cursor_v_pos` (`front.c:285`, externed in `front.h`) instead of the 160/120 centre guess. `MENU_CURSOR_HI_H/_V` / `MID_H/_V` kept only as the fallback. **Verified:** builds + links clean (`getPlayer_c_screen*` and `cursor_[hv]_pos` all resolve — non-static engine symbols, as expected); `GE_STARTMENU=7` mission-select boots crash-free 600+ frames; `-level_09` unregressed (framediff 3/3 within threshold, 91.6% nonclear). The in-level path is untouched (menu-only branch). **Interactive feel-check still owed** — headless input can't drive the mouse pointer, so "every grid tile is now reachable" is inferred from the corrected clamp math, not observed. `Input.MenuPointerMode=0` (legacy velocity) and the constant fallback remain as escape hatches. + +## D178 — Pre-mission briefing screen: objectives blank / missing, briefing pages blank (also the D143 "briefing text blank" side effect) — FIXED (M-36). + +**Pre-mission briefing screen: objectives blank / missing, briefing pages blank (also the D143 "briefing text blank" side effect) — FIXED (M-36).** Root cause: the briefing segment (`Ubrief*Z`, source `assets/obseg/brief/*.c`) is a raw ROM image of `struct BriefStruct` = `{ u16 brief[4]; struct { u16 textid; u16 enabled_difficulty; } objective[10]; }` (48 bytes), loaded by `front.c load_briefing_text_for_stage()` via `_fileNameLoadToAddr()` — **no converter and no BE→LE fixup anywhere in the chain**. On the LE host all 24 `u16` read byte-swapped. Measured on Dam (`GE_D178=1`): raw `brief=002c,012c,022c,032c obj0=042c/0100 obj3=072c/0000` vs correct `2c00,2c01,2c02,2c03 / 2c04/0001 / 2c07/0000`. Two independent symptoms follow: (a) `textid` `0x2C04` (= `getStringID(LDAM,4)`, bank 11 slot 4) reads as `0x042C` → bank 1 slot 44, never loaded → `langGet()` NULL → **blank text** (this is exactly the D143 residual, `front.c:6732` and `brief[0..3]` at `front.c:6855-6867`); (b) `enabled_difficulty` `0x0001` (Secret Agent) reads as `0x0100 = 256`, so `selected_difficulty >= enabled_difficulty` (`front.c:6729`) is false for every difficulty-gated objective — on Agent only the one `DIFFICULTY_AGENT`(0) objective survived the filter, which is why a single bare "a." bullet printed. **Fix:** `romdataFixupBriefing()` in `port/src/romdata.c` (+ `port/include/romdata.h`), called from a `#ifdef PORT` block in `load_briefing_text_for_stage()` right after the load — the same shape as `langFixupLoadedBank()` in `language.c` (BE-serialized-struct reconciliation, semantics-preserving, no game logic touched). `GE_D178=1` prints the raw and fixed words. **Verified:** Dam briefing on Agent now shows "a.

The dominant record sets `gsDPSetCycleType(G_CYC_2CYCLE)` + `gsDPSetTextureLOD(G_TL_TILE)` + `gsDPSetCombineMode(G_CC_INTERFERENCE, G_CC_MODULATEIA2)` and binds **two** tiles: tile 0 = IA8 "smoke" @ TMEM 0, tile 1 = RGBA16 "fire" @ TMEM 0x188. `G_CC_INTERFERENCE` cycle-0 = `TEXEL0 * TEXEL1`. **fast3d's `gfx_lod_tile_offset()` returns `0` unconditionally** on the `!gfx_detail_textures_enabled` branch — a D107 fix for GE's mip textures (whole chain loaded in one LOADBLOCK at TMEM 0; `port/src/video.c:225` sets the flag `false`). So texunit 1's sampled tile = `first_tile_index + 0` = tile 0 → **TEXEL1 samples the smoke texture, not fire** → `smoke * smoke` → wrong colour.

Related, newly reported: **in some cutscenes Bond spins in circles** (named instance: end of Cradle, when Trevelyan falls) — likely the same actor-position/anim-root class rather than a new bug; logged under D148/D160 (`GRAPHICS-BACKLOG.md`) since it's cutscene-triggered. **M-106 investigation (static only — no build/runtime access in this worktree, see note below):** checked the two most D209-shaped candidates for a puppet Y-position aliasing bug and RULED OUT both. (1) `chrSpawnAtPad`/`chrSpawnAtCoord`/`chrAdjustPosForSpawn` (`src/game/chraction.c:10653-10794`) — the puppet-spawn path a cutscene `guard_play_animation`-style AI cmd would use. `PadRecord.stan` (`src/bondtypes.h:1744-1751`) is a ROM-serialized *pointer* field (`StandTile *stan` at offset 0x28) — exactly the tail-pointer shape D122/D126/D132 warn about — and `tools_pc/d88_emit.py`'s `emit_pad()` zeroes it on conversion with a comment claiming it's "dead-on-load, always set before use." **Verified this claim is TRUE, not a converter bug**: every `PadRecord` literal in the N64 source asset tables (checked `assets/obseg/setup/UsetupdamZ.c:37-51`) initialises `stan` to the literal `0` — the ROM binary never carries a live pointer there on N64 either, so zeroing it on PC is byte-identical behaviour, not a regression. `chrAdjustPosForSpawn` receiving a NULL seed `StandTile*` is therefore the original game's normal case, not a port defect. (2) The anim-root-motion Y-accumulation chain (`modelTickAnim`→`modelSetAnimFrame2WithChrStuff`, `model.c:3060+`, `pos24 = pos34 + rotate(pos)` at `model.c:3322`) was already exhaustively audited for exactly this class of bug during D193/D209 (M-80/M-81) and found self-consistent, with the `padding[]`-union sweep that found D209/D210 explicitly noting `act_anim`/`act_dead` (the union arms active during a played-animation/dead puppet) are "layout-stable" (`porting-notes.md` §A, D210 entry) — i.e. that sweep already covers the cutscene-puppet actiontype, and it came back clean. So the two most probable D209-style aliasing sites for this specific symptom are both cold. **Did not find the actual root cause.** Did not get to: the *separate* Cuba end-credits case (`front.c` `init_menu18_displaycast`/`constructor_menu18_displaycast`, `front.c:7821-8320`+ — a **different**, single-actor "cast roster" display model shared by the intro roster and the credits roster, using `getsuboffset`/`subcalcpos`/`cast_rootpos_smoothed` root-motion smoothing, not the in-level chr path at all) — spot-checked `getsuboffset` (`model.c:684-700`) and it is `#MATCH`-verified clean, but did not trace the smoothing math or confirm this is even the code path the "JB above Natalya" report hits (that report implies two actors on screen at once, which this single-`cast_model` code doesn't obviously support — may be a distinct, not-yet-located two-actor cutscene-puppet path). **Confidence: LOW-MEDIUM that this is the D209-style struct-aliasing family at all** — the two most likely aliasing sites check out clean, which argues *against* the shared-root-cause theory for D173 specifically (unlike D160, where the analogous check also came back clean but for a different reason — no pointer fields to alias in the first place). Next investigator: get a live Cradle (`-level_41`) capture of Trevelyan's chr during the death sequence with a position-logging probe (none shipped yet — would need a new `#ifdef PORT` env-gated trace, not added this session per the no-build-verification constraint), and separately locate the actual two-actor Cuba credits code path (grep for wherever `intro_char_table`/cast display is invoked with two simultaneous models, if it exists — not found this session). **M-141: no new lead this session** (see D243's M-141 entry) — checked whether D243's stale-memory front-end/menu bug could share a mechanism with this puppet-position bug; no code-level link found, kept as an unconfirmed hypothesis to watch for during the next live cutscene capture, not a new suspect to chase on its own. **M-141: Steam Deck playtest confirmation** — user reports Bond floating at level start on both Dam and Facility ("chemical plant"), "but fine when it moves to first person" (matches this row's own framing exactly: player spawn/first-person is correct, only the third-person render-side puppet floats). No new mechanism; corroborates the bug is general across levels, not Dam-specific. **User confirms D292** (Bond sunk into the floor on death) **is the same underlying bug**, a third instance alongside level-start floating and the Cradle cutscene spin — see D292 for the consolidated cross-reference. + +## D179 — Packaged build crashes after the logos — the D43/D69 model + bg sidecars are ROM-derived and absent from any build that has no ROM (M-34, alpha-release QA). + +**Packaged build crashes after the logos — the D43/D69 model + bg sidecars are ROM-derived and absent from any build that has no ROM (M-34, alpha-release QA).** The first `goldeneye-pc-port-*-win64.zip` from CI (bundle-win.sh) shows the Rare/Nintendo logos (compiled-in `assets/rarewarelogo.c`) then AVs at `0x6b157a88`/`0x70157a88` — symbolised: `modelPromoteNodeOffsetsToPointers` (`model.c`) ← `load_object_fill_header` (`objecthandler_2.c`) ← first prop/item model load.

General, not chr-specific. **Leading hypothesis — the D117/D134/D155/D156 wall-clock-timing family:** `chr.c` / `chrai.c` integrate movement as `pos += speed * g_GlobalTimerDelta` and step sim loops `while (i < g_ClockTimer)` / `-= g_ClockTimer` (`chr.c:1437,1446,1491-1502,1862,2359,2569`; `chrai.c:76`). On the port `osGetCount()` is free-running wall-clock (D117), `g_GlobalTimerDelta`/`g_ClockTimer` are derived from it, and D155's `FRAMETIMING_PORT_MAX_CATCHUP = 6` clamps `nextFrameTime`. If the effective per-second sum of `g_GlobalTimerDelta` (or the `g_ClockTimer` tick count) runs low — quantization, the catch-up clamp biting during normal play, or a units mismatch (`g_JP_GlobalTimerDelta` vs `g_GlobalTimerDelta`, `chr.c:1435/1437`) — every delta-scaled AI motion integrates slow while **player** movement (input-driven per frame) still feels right, which is exactly the reported split. Related: **D170** (Ourumov/Trevelyan "flee" looks wrong — flagged there as possibly the same locomotion-speed issue rather than an AI divergence). Also possible: `chrGoToBond/Chr(SPEED_RUN/WALK/SPRINT)` speed enum → path-follow step, or pathfinding advancing ≤1 waypoint per frame-quantized tick. **Instances seen (M-49 full playthrough):** (a) Facility — the post-scripted-scene beat with Ourumov + the soldier squad: the soldiers **walk in super slowly and take a long time to path into firing positions** before they start shooting (this is regular squad combat AI, not a named-NPC script — good evidence the slowdown is general delta-scaled `chr` locomotion / path-following, not one ailist); (b) the named-NPC flee behaviour on Silo (Ourumov) and Cradle (Trevelyan) — see D170; (c) **Natalya (the escort NPC) always walks really slow** — on every escort level (Bunker ii, Statue, Control, Archives) she trails far behind, forcing the player to wait. Escort follow-AI is the same `chrGoToChr`/path-follow path as (a). **WORST CASE — Cradle (`-level_51`) is "bugged out completely" due to Trevelyan's behaviour (M-49).** The final level is Trevelyan-fleeing-and-scripted end to end (he runs the antenna cradle, climbs, drops to the cradle floor, the helicopter beat); if his locomotion timing / path-following is off he never hits the trigger points and the level's scripted progression stalls or goes haywire. This makes D193 effectively a **can't-properly-finish-the-game** bug, not just cosmetic sluggishness. **Next:** log `g_GlobalTimerDelta` + `g_ClockTimer` per frame during normal play and check the 1-second sum vs the N64's ~60; time a guard's run across a known distance vs reference footage; then watch Trevelyan's chr state / current AI command on Cradle. + +**Status (from §F table):** **FIXED + user-playtest-verified (M-81) — root cause is D209**: `act_ubytes.padding[45]`, a raw-byte union alias for `act_gopos.unk59` (the SPEED tier), lands on offset 45 which is `unk59` on N64 but is byte 5 of `waypoints[1]` at 64-bit — always `0x00`. So the locomotion-animation selector `get_sound_at_range()` always received tier 0 and bound `ANIM_DATA_walking`/`walking_unarmed` for **every AI chr in the game**, and since travel is anim-root-motion driven they all moved at walk pace no matter what the ailist commanded. User verified on Cradle: Trevelyan and the guards run. Full elimination trail below — **steady-state timing keystone MEASURED and the "sim sums low" hypothesis is CONTRADICTED (M-80).** Added a `GE_D193=1` per-wall-second probe in `waitForNextFrame()` (`src/game/frametiming.c`, `#ifdef PORT`, env-gated): logs render frames, sim ticks delivered (= sum of the `deltaFrames` fed to `updateFrameCounters` = sum of `g_ClockTimer`), catch-up clamp hits, and max raw pre-clamp delta. Built ntsc-final, ran `-level_09 / _20 / _27 / _34` idle-after-load, ~20 s each. **Every level, rock-steady: render = 30.0 fps, sim = 60.0 ticks/s, clamped = 0, maxraw = 2.** i.e. each rendered frame carries `g_ClockTimer = 2` and the per-second sum is *exactly* the N64's ~60 — the wall-clock timer is NOT running low in steady state, and `FRAMETIMING_PORT_MAX_CATCHUP` never bites in normal play. VSync on/off made no difference (still 30/60). So the B1 premise ("`g_GlobalTimerDelta`/`g_ClockTimer` sum low over a real second") is wrong for the common case; D193 must come from elsewhere. **Residual quantization risk (not yet observed):** `nextFrameTime = (dt_counts + 387937) / 775875` is integer-rounded per frame with no remainder carry, so a scene that renders at a *steady* rate between 30 and 60 that is not an integer divisor of 60 (e.g. a solid 50 fps → dt≈20 ms → rounds to 1 → sim 50/s, ~17 % slow) would under-advance; the fix there is a fractional accumulator in the `#ifdef PORT` path. But the port renders a hard 30 (software RSP ≈ 60 µs/frame — not GPU-bound; the cap is the `pendingGfx < 2` double-buffer + sched round-trip), so this only matters if a real AI-heavy scripted scene drops into the 20–30 band. **Next (needs input, interactive session):** drive Bond into the Facility Ourumov/squad beat (D193a) and Cradle Trevelyan run with `GE_D193=1` — confirm render/sim hold at 30/60 under real AI load; if they do, pivot off timing entirely and instrument a single guard's world position vs. distance/time (anim root-motion rate, `chrGoToChr` SPEED_* enum → step size, path-node spacing) — the travel-speed bug is likely in the locomotion/anim path, not the frame clock. `GE_D193` catalogued in `docs/dev/GE-ENV-PROBES.md`. **M-80 cont. — LIVE-LOAD CONFIRMED, pivot is final.** User ran Cradle (`GE_D193=1`, `-level_41` — see the level-id note below) and drove Bond through the Trevelyan sequence while Trevelyan was visibly "walking really slow". Probe throughout: **`render=30 sim=60 clamped=0 maxraw=2`, dead steady** — no dips, no clamp hits, no `[D156]` guard fires. So under the *exact* failing scene the sim clock delivers a perfect 60 ticks/s. **D193 is NOT a timing/scheduler bug — it is in the character locomotion/animation path.** Best current hypothesis: GE character *travel* is animation-root-motion driven — `modelTickAnim` advances `frame += playspeed*speed` per tick (numticks = g_ClockTimer, correct), then `modelSetAnimFrame2WithChrStuff` (`model.c:3060+`) extracts per-anim-frame translation via `sub_GAME_7F06D3F4(...&pos)` and applies `scale = model->scale * model->anim_translation_scale`. The **player does NOT use anim root motion** (explicit speedgo/speedstrafe physics in bondview2.c), which explains the "player fine / all AI slow" split precisely. Suspects, in order: (1) the anim translation keyframe data is decoded with wrong units/scale by its sidecar converter (D43/model family); (2) `model->anim_translation_scale` or `model->scale` misread (ABI/struct-stride — D3x/D99 class); (3) `model->animrate`/`playspeed`/`speed` wrong. **M-80 cont. — port side instrumented (`GE_D193A` in `chrTick`, `GE_D193B` in `sub_GAME_7F06D3F4`; both `#ifdef PORT`, catalogued in GE-ENV-PROBES.md). Findings:** (i) `g_GlobalTimerDelta = 2.0`, `model->playspeed = 1.0`, `model->scale = 0.1`, `model->anim_translation_scale = 1.0` for every ticked chr on Silo + Facility — the scalars that feed the root-motion accumulation are all nominal, matching the identical N64 C (no `#ifdef PORT` in this hot path bar the non-firing D156 NaN guards). `model->animrate = 0.0` universally but that is the default — only written by `modelSetAnimPlaySpeed` on a blended transition (`startframe > 0`), so not the bug. (ii) Patrolling guards (`act=14 ACT_PATROL`, `model->speed=0.5`) travel **~60–99 world-u/s** on the port — no N64 number to compare against yet. (iii) `GE_D193B` (Facility, walk anim `706af4d8`): the decoded root-motion triple `tmp` ≈ (±0-3, ~1080-1094 hip height, ±0-50) with **`base = 0` and `angle = 0` on every call** (could be legit for a straight-line walk — joint 0 channel A at index 0, no per-frame facing change — or could be a mis-selected/zeroed channel; can't tell without the N64 side). **Bottom line: every port-side input to the locomotion math reads nominal**, so the divergence is either (a) subtle wrong magnitudes in the decoded anim bitstream values themselves (`tmp` triple / the descriptor decode), or (b) something in the `pos34` accumulation / `header->unk*` state — neither visible without a reference. `ModelSkeleton` **ruled out** — the skeletons are statically defined in C (`New_ModelSkeleton`/`MODELSKELETON` macros, `chrobjdata.c` etc.), not ROM-serialized, so `Joints` is a native x86-64 pointer and `ModelJoint` is 6 B on both platforms; `base` is correct. That leaves the ROM-serialized `ModelAnimation` bitstream (`bitDescriptors`/`bitStream`, D32-widened) and the anim-table load path as where a magnitude error could enter. **M-80 cont. — anim-data endianness (D33) audited, looks complete for this path.** `ptr_animation_table` is `romCopy`'d then byte-swapped by `romdataFixupAnimationData` (`port/src/romdata.c`, D33): per 20-byte record it bswaps `+0x00/+0x04/+0x08/+0x0C/+0x0E/+0x10` and per 6-byte `ModelAnimBitField` descriptor bswaps `+0 bitOffset` / `+4 valueOffset` (bitCount/pad identity); the bit*stream* is left raw (correct — `modelAnimReadRootMotionValue` walks it byte-by-byte, MSB-first, endianness-neutral, same as PD's `anim_read_bits`). `PTR_ANIM_walking/running/sprinting` **are** in `animation_table_ptrs1` so guard-locomotion records do get fixed up; `_ptrs2` is only 3 helicopter/plane anims (no overlap → no double-swap). No `bad descriptor range` / `bad record offset` errors in any run. Every `anim->unkNN` the locomotion path reads (`unk04`, `unk06`, `unk07`, `unk0C`) is within the fixed-up 0x14 bytes. `sizeof(ModelAnimation)` = 64 B both platforms (D32 kept the embedded ptrs as `u32`); `sizeof(ModelAnimBitField)` = 6 B both. So the anim decode is structurally sound as far as static review goes — **a magnitude error, if any, needs the N64 reference to see.** **Next — two viable paths (needs a fresh session; toolchain not present here — no `mips-linux-gnu-*`, no `qemu-irix`, no emulator):** (A) set up the MIPS toolchain + IDO-recomp + an N64 emulator with `osSyncPrintf` capture, build the ROM with `#ifndef PORT` `GE_D193B`-equivalent logging, navigate to the same scene, diff `tmp`/`base`/`angle`/travel-speed against the port capture; (B) user records N64 footage (real HW or their emulator) of one guard traversing a measured distance, frame-count it → gives the port-vs-N64 speed ratio (a clean 2× would point at a per-frame vs per-tick doubling; a fractional ratio at a scale/data error). Recommend (B) first — cheap, and the ratio narrows (A) massively. **Highest-impact playtest finding — breaks Cradle.** **Level-id note:** the earlier "Cradle = `-level_51`" in this row and HANDOFF was WRONG — `LEVELID_CRADLE = 41` (`src/bondconstants.h:1662`; STATUE=22, so CRADLE = 22+19). `-level_51` = `LEVELID_EAR` (unused slot) and SIGSEGVs at load in `stanBuildRoomData` (`stan.c:281`, NULL deref) — a non-issue (bad level id), noted here only so it isn't re-investigated as a real crash. **M-81 — SOLVED, and none of the M-80 suspects were the cause.** Re-verified the whole timing chain independently (`waitForNextFrame` -> `speedgraphframes` -> `g_ClockTimer` -> `g_GlobalTimerDelta`; `g_GlobalTimer += g_ClockTimer` at `lv.c:1022` is **tick**-based, so the ~75 AI timeout comparisons against it are frame-rate independent) and re-checked the D33 fixup *widths* against the real structs (they match exactly, and `(bs-bd) % 6 == 0` passing is independent evidence the two embedded pointers decode correctly). Root-motion accumulation is self-consistent (`pos24 = pos34 + rotate(pos)` at `model.c:3322`, so `pos` is a per-frame delta in x/z and an absolute hip height in y — matching the observed `tmp` shape). Extending `GE_D193A` with the visibility-gate counters (`tick`/`move`, i.e. chrTick entries vs `chrUpdateAnim` calls) killed the culling hypothesis too — chr 0 is `31/31` every second. The tier was then shown correct (`tier=1 SPEED_RUN`) and the *animation* wrong (`aidx=40/107`, never 42/41), which is **D209**. Note for future readers: `chrlvApplySpeed`'s `speedPtr` out-param is a **turn** rate, not a travel rate (`chraction.c:8070` passes `&act_runpos.turnspeed` into it), so `act_gopos.speed == 0` just means "running in a straight line" — it is not evidence of a stalled character. + +## D194 — Mouse input needs another tuning pass — RMB aim over-sensitive + sensitivity couples to frame/sim rate (M-49, user playtest). + +**Mouse input needs another tuning pass — RMB aim over-sensitive + sensitivity couples to frame/sim rate (M-49, user playtest).** Two parts. **(a) Aim mode (RMB) is near bang-bang, not proportional** (`port/src/input.c:697-707`): any per-poll delta past `AIM_MOVE_THRESH` emits stick `m = clamp(61 + |Δ|·(MouseAimSpeed/100)·AIM_GAIN, 61, 60+AimBand)` = `[61,80]` — with the M-29 defaults (`MouseAimSpeed=16`, `AIM_GAIN=4.0`, `AimBand=20`) `m` is already 61 (fast) at ~1.5 px/poll and saturates at 80 by ~30 px/poll, so the usable proportional band is tiny and sits near the top of GE's aim range → "way too sensitive," turn rate barely tracks how fast you actually move the mouse. Needs a real response curve (low floor, wider proportional band, maybe a gamma), not a threshold+clamp. **(b) Overall sensitivity correlates with movement/frame rate** (user's words: "correlated with movement speed, does not feel good"): `input.c` emits raw stick counts **per controller poll** with no `g_GlobalTimerDelta` / polls-per-frame normalization (hipfire yaw `sx += edx·(MouseTurnSpeed/100)·6.0` at `:709`; aim as above). GE integrates the stick scaled by its sim delta, and the port's poll cadence vs render/sim cadence drifts with scene load — so effective sensitivity shifts when the framerate does (which reads as "when I'm moving"). Fix direction: accumulate mouse delta and convert to stick using a fixed reference dt (or feed the game a dt-consistent value), so a given hand motion = a given view rotation regardless of fps. Lineage: D118a (hipfire pitch digital vs analog), D165 (menu pointer), D166 (hipfire pitch pulses), D180-B3 (`MouseAimSpeed` 25→16). New adjacent QoL ask, root-caused → **D223** (mouse-wheel direction should reverse weapon cycle direction, currently both directions cycle forward). Config knobs exist (`Input.MouseAimSpeed/AimBand/MouseTurnSpeed/HipfirePitchSpeed`) but the *shape* of the mapping is the problem. **M-87 design-goal note (user):** overall mouse feel should move toward **Quake Remaster / the Perfect Dark PC port** — raw, direct, responsive 1:1 mouse-look — while explicitly **not losing GE's original aiming nuance** (the analog-stick aim-mode vs digital-hipfire split this whole D118/D194 lineage exists to preserve). Reframes the fix direction from "just widen the proportional band" to: normalize by a fixed reference dt first (part (b), the frame-rate coupling — this alone should fix most of "feels unresponsive"), then re-derive the aim-mode response curve, and treat raw hipfire mouse-look (PD/Quake-style, bypassing the N64 digital-stick emulation entirely when the player is *not* in aim mode) as a real design option to evaluate against "keep GE's aim-mode feel," not assume the N64 stick-emulation path is mandatory everywhere. **M-87 — found it: GE already has exactly this control scheme, unused by the port.** User asked why vertical mouse feels less responsive than horizontal; investigation found the port forces `controldef = CONTROLLER_CONFIG_HONEY` (1.1), under which hipfire pitch is genuinely digital-only (C-up/C-down) while yaw is analog — an intentional N64-era asymmetry (D166), not a port bug, but avoidable. **`CONTROLLER_CONFIG_SOLITARE` (1.2) / `GOODNIGHT` (1.4)** — user's own recollection, verified in code — redirect forward/back/strafe-L/R onto digital C-buttons/D-pad (`bondview2.c:5195-5253`, `moveData.digitalStep{Forward,Back,Left,Right}`), which frees the **entire primary analog stick** for continuous, unclamped pitch **and** yaw: `moveData.canNaturalPitch`/`canNaturalTurn` (set `!insightaimmode`, i.e. active outside aim mode, not gated behind holding aim) drive `analogPitch/70.0f` / `analogTurn/70.0f` directly (`bondview2.c:5950`/`6008`) — no threshold, no digital step, no `[61,80]`-style clamp band (that clamp is specific to the *aim-mode* zoom-turn path, a separate codepath, `insightaimmode && stick_y>60`). `analogPitch`/`analogTurn` default to the primary stick's raw X/Y for every 1.x scheme (`bondview2.c:4881-4882`) unless a 2.x dual-controller scheme overrides them from a second controller. **This is architecturally identical to a modern FPS mouselook**: continuous analog look on the stick, discrete step movement on buttons — a legitimate, unmodified original GE control scheme, not a port invention. Recommended fix: force the port's `controldef` to SOLITAIRE or GOODNIGHT instead of HONEY, map WASD to the digital step-movement buttons (already close to how keyboard hipfire movement works today) and mouse X/Y directly to the primary stick's continuous X/Y — this should resolve the vertical-vs-horizontal asymmetry completely (no more digital-pulse emulation needed at all, D166 becomes largely moot) and likely fixes much of "feels unresponsive" too, since it's direct continuous stick input rather than any thresholded emulation. The frame-rate-coupling issue (part b) is orthogonal and still needs fixing regardless of scheme. Cross-ref D166, D223 (control-preset forcing — this gives a concrete "which preset" answer). **Aim-mode note:** the port's aim-mode code (`input.c:777-784`) already applies the same gain formula to both mouse axes symmetrically — if vertical still feels worse *while aiming* (RMB held), that's a separate, unconfirmed issue, not explained by any of the above. **M-87: user independently confirms part (a)** ("right mouse aim is way too sensitive") and suggests the design fix — aim sensitivity should scale off the **same base per-pixel sensitivity as normal (hipfire-turn) mouse movement**, not its own disconnected curve. Concretely: today hipfire turn is a direct accumulation (`sx += edx·(MouseTurnSpeed/100)·6.0`, `input.c:709`) while aim is the separate floored+clamped `[61,80]` stick-value synthesis (`AIM_GAIN`/`AimBand`, unrelated constants) — two independently-tuned systems that don't agree on what "1 inch of mouse" should mean. Aim mode is a distinct codepath from hipfire (gated by `insightaimmode`, **untouched by the SOLITAIRE scheme change above** — natural-pitch/turn is explicitly `!insightaimmode`), so this needs its own fix regardless of the control-scheme switch. Fix direction: derive the aim-mode mapping from the same base sensitivity constant as hipfire (`MouseTurnSpeed`-equivalent), scaled down only by the aim-zoom's FOV narrowing if any adjustment is wanted at all, rather than the separate `AIM_GAIN`/`AimBand` floor+clamp system — so moving the mouse the same physical distance feels the same whether or not aim is held, without losing GE's own aim-precision character. + +**Status (from §F table):** **PARTIAL — M-120 human playtest: hipfire/primary look is GOOD now, aim-mode (RMB/Shift) is STILL too sensitive, unusable for precision aiming.** Part (b) (dt-decouple) + the SOLITAIRE natural-pitch scheme switch (part of this PR's combined pass) are user-confirmed working well on PR #62 — normal look feels right. **Part (a) (aim-mode response curve) does not deliver the intended fix despite being "implemented."** User's words: "right mouse / shift aiming with crosshair is still way too sensitive and does not feel right / is not usable in game." Code-level re-read of `port/src/input.c`'s `aimHeld` branch (~line 939) finds a likely concrete cause the original D194(a) design didn't eliminate: `m = AIM_STICK_MIN + pow(normX, gamma) * (AIM_STICK_GAME_MAX - AIM_STICK_MIN)` — the response curve (`aimCurveGamma`, gamma=1.6 default) only shapes the range **above** the `AIM_STICK_MIN=61` floor; the instant `|aimEdx| >= AIM_MOVE_THRESH` (a tiny 0.3 px/poll), stick jumps straight to 61, i.e. **10% of the game's max aim-turn speed (`(stick-60)/10` clamped 1.0), with no ramp from zero.** For hipfire comparison, the non-aim path (`hipEdx * hipSens * MOUSE_TURN_GAIN`, no floor, no threshold-snap) is fully proportional to zero — structurally different, and the one the user says feels good. Aim mode's floor+threshold-snap behavior reads exactly like the original "near bang-bang" M-49 complaint the curve was meant to fix, just now confined to the bottom of the range instead of the top. **Not yet build/runtime-verified** — this is a static code-read hypothesis, not a confirmed root cause; needs an env-gated probe or a tuning pass (e.g., drop `AIM_MOVE_THRESH` toward 0 and make the curve span `[0, AIM_STICK_GAME_MAX-AIM_STICK_MIN]` from a true zero floor, or lower `AIM_STICK_MIN` itself for a genuine near-zero low end) before another playtest. **PR #62 (`fix/d194-mouse-dt-decouple`) stays held, unmerged** — part (a) needs another iteration; parts (b)/SOLITAIRE are ready to land whenever the aim-mode fix is folded in and re-tested together. **M-122: all four stick-synthesis models above were abandoned.** GEPD's own source (`MouseInjectorPlugin/games/goldeneye.c`) was found and read: it never synthesizes a stick for aim at all — it directly overwrites `crosshair_x/y_pos`, `gun_azimuth_angle/turning` (its formulas, RATIOFACTOR=1, basefov) and edge-scrolls the camera past 72% of the way to the screen edge. The port now mirrors that exactly in `port/src/input.c aimGepdCompute()` (knobs `Input.AimAbsolute`, `Input.GepdSens`); no look stick is emitted while aiming, and the game's own damped crosshair update (`caclulate_gun_crosshair_position_rotation`, gunfire.c:4819) is left running — GEPD patches nothing there either, its per-frame overwrite simply wins. **User verdict: "mechanically it works... the aim mode works how we'd want."** Committed `ef49d9e6`. Residuals: ① crosshair/arm spazz glitch, ② aim-mode FPS drop, ③ sensitivity tuning (see M-122 in HANDOFF). **M-123: playtest log (`d194_gepd.err`, 1964 gepdaim lines) mined for ①.** Result: the port's own writes are rock-stable — zero crosshair/camera jumps while aim is held; every large camera delta in the log turned out to be user hipfire stick swings between polls. Exactly ONE true anomaly: a +359° one-tick spike in raw `vv_theta` (cam 0.5 → 359.7, log line 534) — the port's own `[0,360)` wrap of the edge-scroll accumulator firing when the game held a small positive angle and a leftward scroll crossed zero. GEPD does a bare `camx += ...` with no wrap, and the game itself never wraps `vv_theta` in on-foot play (`bondviewApplyVertaTheta` only sin/cos's it; tank code is the sole wraper), so the wrap was removed (port-only). Note: the handoff's theory that this feeds the crosshair via `speedtheta` does not hold — `speedtheta` comes from stick input (`bondview2.c:6056`), never a `vv_theta` delta; all solo-play consumers of `vv_theta` are sin/cos or `(360−θ)` rotations (raw-delta consumers at bondview2.c:1361/9397 are MP-only). The spazz must therefore live in the game-side terms added on top of our overwrite each tick (`turn_x = autoaimx | speedtheta*0.3`, `turn_y = autoaimy | −speedverta*0.1`, gunfire.c:4819 loop) — prime suspect: auto-aim pull oscillating as lock-on jitters, worst near enemies (matches the user's report). The gepdaim log line now also prints the pre-overwrite residue (`game=` = last tick's `pos·damp+turn`), `aa=(autoaimx,autoaimy)`, `st/sv` (speedtheta/speedverta) so a live capture can confirm or kill that. Tick ordering checked: our write runs BEFORE `bondviewProcessInput` each tick (osContStartReadData → inputComputePad, libultra.c:1094), vs GEPD writing after game code — but the displayed fixed point (`X·damp+turn`) is identical either way in steady state, so ordering is not a spazz source by itself. Suspect (c) 2px deadband does not apply to the GEPD path (deadband lives only in the legacy fallback); suspect (d) centre-spring nudge is ~0.1–0.3° over its 2 ticks — negligible, kept (it clears `docentreupdown`, which must not fight aim). **M-123 user playtest (post wrap-fix + extended logging, `GepdSens` 25): "looks good... other than sensitivity we're good, 95%"** — residual arm/gun/crosshair glitching accepted as playable; ① closed as acceptable, remaining D194 work is ③ live sensitivity co-tune (`Input.GepdSens`, ini at 30 at session end) and the still-uncontrolled ② aim-mode FPS retest (logging off). **D194 CLOSED (post-merge):** ③ done (hipfire/aim aligned, defaults `AimModeSens=38`/`MouseTurnSpeed=50`, merged `f239adf5`) and ② resolved by user report -- "no performance [issue] is good now" during the calibrated playtest sessions; the formal logging-off control was never run but the original ≤10fps complaint did not recur, so it is closed on user evidence (revisit only if an FPS regression appears later). + +## D195 — Transparency / alpha surfaces broken on Control (M-49, user playtest) + +**Transparency / alpha surfaces broken on Control (M-49, user playtest)** — Natalya's console room, the glass partitions + translucent projected wall displays. Originally reported as a blend-state defect. Reinvestigated this session (M-116) after the user reported the glass rendering **solid black** — traced to a real, separate, much bigger bug: `G_TEXTURE_GEN` (RSP environment-mapped texture coordinates, used by shiny/reflective materials game-wide — gold/silver weapon skins, chrome trim, and this glass) was never implemented in fast3d. D72.1 (an earlier session) removed the PD-inherited envmap UV-generation block wholesale to fix the Rareware logo, reasoning "GE never generates texture coordinates from vertex normals" — true for the logo (lit, but does not set `G_TEXTURE_GEN`) but false in general: every envmap draw was left sampling whatever raw `tc[]` happened to be authored (near 0), landing on a fixed corner texel of the reflection map every frame regardless of view angle — for a typically dark-edged reflection texture, a solid near-black surface. + +**Status (from §F table):** **FIXED (`port/fast3d/gfx_pc.cpp`, `gfx_sp_vertex`) — restored envmap UV generation gated on the real `G_TEXTURE_GEN` bit** (ported from the reference Perfect Dark PC port's already-correct implementation), so D72.1's actual fix is untouched (the logo never sets this bit) while every other envmap draw gets real reflection coordinates. **User-verified live:** console glass and shiny gold/silver guns are now visibly reflective instead of flat black. Confirmed crash-free on a full 21-level sweep. **The remaining "not translucent" complaint is NOT a bug**: user confirmed after seeing the fixed reflective glass that it was never see-through on the original N64 either — it's a reflective (mirror-like) surface by design, not transparent glass. Traced (before the user's confirmation settled it) to the material's own combine formula, `alpha = (TEXEL0/1 LOD-crossfade alpha) * SHADE_alpha + PRIMITIVE_alpha` — an additive constant term that saturates alpha near 1.0 by design, matching "reflective, mostly opaque" intent, not a blend-state defect. **Closed.** Cross-ref: this same envmap fix likely also explains part of D228 (white NPC-weapon patches) if any of those are chrome/shiny weapon variants — worth checking before further D228 investigation. + +## D197 — Character face/head textures wrap around the head, seen on Silo (M-49, user playtest). + +**Character face/head textures wrap around the head, seen on Silo (M-49, user playtest).** Reads as `G_TX_CLAMP` not honoured (or a non-power-of-two wrap period) on a head/face texture tile — the texture repeats around the mesh instead of clamping at the UV edge. Not yet isolated to a specific character or texture; no `GE_PCDUMP`/`GE_TEXDUMP` capture taken.

Every sibling call site in `env.c`/`resample.c`/`reverb.c` already resolves state pointers via `osVirtualToPhysical` (the port shim, `port/src/libultra.c`), which is bit-identical to `K0_TO_PHYS` for real N64 kseg0 addresses but correctly PC-shimmed. **Fix (ABI-layer, `#ifdef`-free — same call resolves correctly on both platforms):** replace the 3 `K0_TO_PHYS(...)` calls with `osVirtualToPhysical(...)`.

GE uses the classic IDO libaudio ABI (verified against every call site in `src/libultra/audio/*.c` + `src/libultrare/audio/{env,reverb}.c`), not PD's differently-shaped "naudio New" ABI — DSP math (ADPCM decode, linear resample, linear envelope mix) is the same Nintendo/SGI ucode PD's `mixer.c` already ported; only the ABI/addressing layer is GE-specific and new here. Several opcodes (`aADPCMdec`, `aResample`, `aEnvMixer`, `aLoadBuffer`, `aSaveBuffer`) take only a state/DRAM pointer — their DMEM source/dest addresses and byte counts come from the most recent `aSetBuffer` call(s), which there is no RSP disassembly to check against; the persistent-context shape (`sCtx.{in,out,count,dryR,wetL,wetR}`) was reconstructed purely from reading every `aSetBuffer`+opcode call-site pair across `resample.c`/`load.c`/`reverb.c`/`mainbus.c`/`save.c`/`env.c` (see the field comments on `sCtx` in `mixer.c:52-82`). `aSegmentImpl` is a no-op — GE's audio DRAM addresses are already resolved via `osVirtualToPhysical` before reaching the mixer (see D198), so segment/base never factor into DMEM addressing here. **Risk:** the `aSetBuffer` context reconstruction is an inference, not a verified spec — if a call site this session didn't audit sets the context differently, audio for that path will mix from the wrong DMEM offsets. **Verified:** `-level_09` now runs full music + SFX 120s+ crash-free (post-D200 fix); no cross-level or opcode-level audio-correctness verification done yet (no golden-audio comparison tooling exists). + +**Status (from §F table):** LANDED (`port/src/mixer.c`, `port/include/mixer.h`, `include/PR/abi.h`) — functional on `-level_09`, context-inference risk noted, needs a wider level sweep + +## D196 — OS mouse cursor stays visible after closing the F10 options overlay in click-to-lock mode (M-49, user playtest). + +**OS mouse cursor stays visible after closing the F10 options overlay in click-to-lock mode (M-49, user playtest).** `Input.MouseCaptureMode=1`.

So the effective clamp is still ~300/220 while the mission-select grid's outer split points sit at 317 / 235.5 (`front.c:516/519/3180/3194`) — outer columns + bottom row unreachable, P-controller winds up and never settles. `MouseCaptureMode=1` (the shipped default, click-to-lock) writes `cursor_h_pos`/`cursor_v_pos` directly from the absolute OS cursor (`input.c:629-657`) and *feels* fine, though it shares the bad `hiH` so the last few px at the right/bottom edge may still be short. **Not a v0.1.0 blocker** — default mode is acceptable, always-grab is opt-in via INI, front-end roughness is already in the release notes. **Fix (port-only, small):** in the `menuMode` branch, when `current_menu` is a front-end menu use the real front-end rect (hard-code `front.c`'s cursor clamp `[20,420]×[20,310]`, or read the front-end viewport global) instead of routing through `g_CurrentPlayer`.

The player's per-hand fire sound is double-buffered across two handle slots: `hands[h].audioHandle` (`ALSoundState *`, correctly pointer-width) and `hands[h].field_A48` (`s32`). `gunfire.c:3186-3200` (`bondfirefunc`) each trigger interval calls `sndPlaySfx(bank, idx, (ALSoundState *)&handptr->field_A48)`, and `sndPlaySfx` writes the new state through it as `pendingState->link.next = nextState` — an **8-byte pointer store** into a 4-byte field, overrunning into the adjacent `field_A4C` (which is the auto-fire sound-cadence timer, written back every frame at `gunfire.c:3168`). `sndUnlinkClearSound` likewise does an 8-byte `state->state->link.next = NULL` there. The two writers stomp each other; after enough double-buffered fire cycles `field_A48` holds a value that is neither `0` nor a valid pointer, so the `else if ((ALSoundState *)handptr->field_A48 == 0)` re-arm gate in the double buffer is **never true again → no further player gunshot is ever issued.** `audioHandle` alone can't cover because the code only replays into it `if (audioHandle == NULL)` and the async `sndDeactivate(audioHandle)` leaves it briefly non-NULL, deferring to the jammed `field_A48` branch. **Evidence (user Bunker capture, `audiotrace.log`, silenced PP7 = idx 46):** idx-46 `sndPlaySfx` requests stop dead at t=776609203515 (log line 18930 of 25086) while guard fire (109), pickups (232), impacts, doors all continue to the end; at line 19159 the player-gun slot `0x70076630` is caught holding `was 0x000001db00000000` — a torn 64-bit value = `field_A48=0x00000000` + `field_A4C=0x1db` (475, a `g_GlobalTimer`-relative cadence stamp) read as one word. The alarm is not required — it just raises `sndPlaySfx` churn so the tear is hit sooner. On N64 both fields are 4 bytes, `audioHandle` is a 4-byte pointer, and `&field_A48` punned as `ALLink*` is a 4-byte `link.next` write — all consistent, no overrun. **`bondview` / `hands[]` is runtime-only state (`g_CurrentPlayer`), never ROM-serialized**, so widening `field_A48` to pointer width is layout-safe (no by-offset or ROM-cast access — grep-verified; only `field_A50`/`field_A4C` sit after it and are plain `s32` timers). + +**Status (from §F table):** FIXED + user playtest-verified (M-78d) — Bunker firefight: player gunshots persist through the whole engagement and survive the klaxon stopping.

Its **only** caller, `play_hit_soundeffect_and_proper_volume()` (`chraction.c:3665`), passes the tier as `self->act_ubytes.padding[45]` — a raw byte read out of the `ChrRecord` action union rather than the named field. On N64 that alias is exact: `struct act_gopos` = `{coord3d targetpos@0, StandTile *target@12, waypoint *target_path@16, waypoint *waypoints[6]@20, u8 curindex@44, u8 unk59@45}`, so `padding[45]` **is** `unk59`. On x86-64 the three pointer members widen 4→8 B (`target@16, target_path@24, waypoints@32`), pushing `curindex`→80 and `unk59`→**81**, while the literal `45` now lands inside `waypoints[1]` (spanning 40..47) — specifically **byte 5 of a heap pointer**. The port's arena is low-4GB (`0x00000000_70xxxxxx`), so byte 5 is **always `0x00`** → `arg1 = 0` → `ANIM_DATA_walking` / `ANIM_DATA_walking_unarmed`, unconditionally, for every AI chr on every level since the 64-bit transition. The named-field reads (`chrlvApplySpeed(self, ..., (s32) self->act_gopos.unk59, ...)` at `:9104`, and the `unk59 == 2` / `== 1` `modelSetAnimSpeed` tiers at `:9106-9130`) resolve correctly, which is why the tier *looked* right everywhere it was inspected — only the alias was broken. **Runtime evidence (Cradle `-level_41`, `GE_D193A` extended with `tier`/`aidx`):** all six chrs report `act=15 ACT_GOPOS tier=1 SPEED_RUN` on 420/440 samples, yet `aidx` (live `model->anim` reverse-resolved against `animation_table_ptrs1`) is **40 = `PTR_ANIM_walking`** for Trevelyan (chr 0) and **107 = `PTR_ANIM_walking_unarmed`** for the guards on every single sample — `aidx 42 (running)` / `41 (sprinting)` never appear. Travel speed sat in a flat 140–155 u/s band for all of them, independent of animation, which is the walk-cycle stride. `act_ubytes` has exactly one use in the whole tree, so this is a single site. Both callers of `play_hit_soundeffect_and_proper_volume` reach it with `actiontype == ACT_GOPOS` (`:3723`, immediately after `actiontype = ACT_GOPOS; act_gopos.unk59 = speed;`; and `:9087`, inside the explicit `else` of `actiontype == ACT_PATROL`, mirroring the `chrlvApplySpeed` split directly below it), so reading the named field is exactly the byte N64 reads — no behavioural change. + +**Status (from §F table):** **FIXED + user-playtest-verified (M-81).** `chraction.c:3665`, `#ifdef PORT` → `get_sound_at_range(self, self->act_gopos.unk59, ...)`; the N64 line kept verbatim under `#else`.

Fix: factored the existing widen-FOV math out of `fr.c` into `f32 portScaleFovY(f32 fovy, s32 isTitleScreen)` (`port/src/video.c`, D222 — identical logic, same `LEVELID_TITLE` guard, no game-code duplication) and fed it into all 4 `currentPlayerSetPerspective()` call sites via a small `#ifdef PORT` local helper in `fr.c` (`frCullFovY`), same as the existing D211 projection-matrix chokepoint now also calls the shared helper instead of its own inline copy. Identity (bit-for-bit no game-code-visible change) at `FovScale=100` by construction — `portScaleFovY` returns `fovy` unchanged whenever `portFovScale == 1.0f`. Audited per the original risk note: `c_cameratopnorm`/`c_cameraleftnorm`/`c_scalelod`/`c_lodscalez` are consumed only in `propobj.c`'s fog-visibility-fade math and `bondview.c`'s own screen-space transform — no AI-visibility/awareness call sites found reading these fields, so `portFovScale` still only touches rendering-adjacent visibility, not NPC behavior. Rebuilt clean, crash-free at `FovScale=150` on `-level_33` (Dam). `bunker1` golden framediff was inconclusive in this dev box — the *unmodified* baseline build also fails it by a similar or larger margin (confirmed via an A/B stash/rebuild), matching the documented pre-existing frame nondeterminism (`porting-notes.md` §E), not a regression from this change. **Needs a human's eyes**: does high-`FovScale` screen-edge NPC/object culling actually look fixed now. + +## D223 — QoL ask: mouse-wheel weapon cycling should be directional like a normal PC shooter — wheel up = next weapon, wheel down = previous — instead of both directions… + +**QoL ask: mouse-wheel weapon cycling should be directional like a normal PC shooter — wheel up = next weapon, wheel down = previous — instead of both directions cycling forward (M-87, user QA).** **Root-caused, port-only fix, no game-logic change needed** — GE's engine already has separate forward/backward weapon-cycle signals: `bondview2.c` computes `moveData.weaponForwardOffset = edge(invButtons) && !(shootButtons held)` and `moveData.weaponBackOffset = (invButtons held) && edge(shootButtons)` (`bondview2.c:5338-5347`, the classic N64 "hold A, tap Z to cycle backward" trick). Default control scheme (the `else` branch used unless a Domino/Goodhead/Galore/Plenty preset is active, `bondview2.c:5177-5179`): `invButtons = A_BUTTON` (= port `GE_CONT_A`, `input.c:86`), `shootButtons = Z_TRIG` (= port `GE_CONT_G`, `input.c:88`, the fire button). `moveData.triggerOn` is explicitly suppressed while `invButtons` is held, so holding A never causes an accidental shot when the Z edge lands. The port's `inputPostWheel()` (`input.c:977`) currently does `if (notches < 0) notches = -notches` — **discards wheel direction** — and only ever synthesizes a bare `GE_CONT_A` pulse (`wheelPulse`, `input.c:631-634`), i.e. always "forward." + +**Status (from §F table):** **FIXED (M-105, `port/src/input.c`) — directional wheel cycling implemented per the plan below.** Wheel-up keeps the existing 2-poll `A` pulse (`weaponForwardOffset`: fresh A edge, Z released). Wheel-down runs a 2-poll backward sequence: poll 1 presents `A` only, poll 2 presents `A`+`Z_TRIG` — the fresh-Z-edge-while-A-held combo `weaponBackOffset` requires (`bondview2.c:5337-5340`); ordering matters because the edge is computed against the game's own previous poll. `moveData.triggerOn` (`bondview2.c:5419`) requires A to be released, so the synthesized Z edge can never fire a shot. Roles are stable: the port forces `CONTROLLER_CONFIG_HONEY` (`bondview.c:1484`), whose scheme gives `invButtons=A_BUTTON`/`shootButtons=Z_TRIG` — the same roles the pre-fix forward pulse already relied on. Known limitation (pre-existing, not a regression): while RMB aim is held the game flips `controldef` to KISSY (`bondview2.c:6106-6112`), under which *neither* direction cycles — exactly as the old forward-only pulse behaved in that state. Owes a human play-test (wheel up = next weapon, wheel down = previous, no accidental shots). Plan: keep `wheelPulse` (or a new `wheelPulseFwd`) for wheel-up as today; add a `wheelPulseBack` path for wheel-down that instead holds `GE_CONT_A` across ≥2 polls while presenting a fresh `GE_CONT_G` edge partway through (mirroring the invButtons-held + shootButtons-edge combo) — sequence matters (A must already read "held" `oldbuttons`-wise before G's edge, per `weaponBackOffset`'s check order). Must confirm which N64 control preset (`controldef`) the port's save data actually carries — `invButtons`/`shootButtons` differ under KISSY/GOODNIGHT/SOLITARE/etc; if the port doesn't force one, the synthesized combo needs to match whatever's active, or the port should just force the default (HONEY-equivalent) preset since its own `Input.Bind` system already replaces N64-style scheme selection. Port-only, `#ifdef PORT` in `input.c`, no `src/` game-logic touch. **M-87: PD-PC-port precedent checked (user asked what PD did about N64 control presets).** PD does **not** route mouse/gamepad through the N64 preset system at all — it defines its own logical control-key layer (`CK_*` in `port/src/input.c`/`input.h`, e.g. `CK_DPAD_L`/`CK_Y`) fully decoupled from the N64 controller-config enum, and even treats mouse-wheel-up/-down as **two independent bindable virtual keys** (`VK_MOUSE_WHEEL_UP`/`_DN`, defaulted to distinct `CK_*` actions) rather than one "wheel = cycle" event — exactly the shape of the fix this row wants. PD's `controldef` field is hardcoded (`player.c`/`playermgr.c` `controldef = 2`), not left to the original in-game control-style picker. **This GE port already has the equivalent layer for this purpose: D214's `Input.Bind` system.** Recommendation for D223 (and the user's broader ask — N64 presets aren't meaningful for mouse/keyboard, and modern-gamepad (Xbox/PS) support should be a first-class port concept, not routed through N64 presets either): add two new `Input.Bind`-able logical actions (e.g. `IA_WEAPON_NEXT` / `IA_WEAPON_PREV`) that synthesize the invButtons/shootButtons combos under the hood, default-bound to wheel-up/-down (keyboard/mouse) and left open for a future bumper/shoulder-button default under real gamepad support; and have the port force a single fixed `controldef` (matching PD's approach) so the synthesis target never depends on the original N64 control-style menu. That menu itself becomes a candidate for hiding/no-op in a future QoL pass once `Input.Bind` fully supersedes it — not proposed as a change here, just noted as the natural conclusion. **M-87 — D194 gives a concrete answer for *which* preset: `CONTROLLER_CONFIG_SOLITARE` (1.2).** It's the scheme that gives free continuous full-stick mouselook (see D194) — and conveniently, `SOLITARE` is **not** in the `KISSY`/`GOODNIGHT` button-role group (`bondview2.c:5168-5179`), so it keeps the **same** `shootButtons=Z_TRIG`/`invButtons=A_BUTTON` roles this row's plan already assumed — no change needed to the wheel-cycle synthesis. (`GOODNIGHT` (1.4) also gets natural pitch/turn but groups with `KISSY` for button roles — `shootButtons=A_BUTTON`, `invButtons=L_TRIG|R_TRIG` — so it would need this row's combo re-derived; prefer SOLITARE unless something else needs GOODNIGHT specifically.) **M-87 survey note, filed for later (candidate 4, no action needed now):** GE's port has no per-player control-*mode* concept — keyboard/mouse is always controller 0 (`inputOpenPads()`, `connectedMask=0x1`), covering the common "P1 mouse+kb, P2+ pads" local-MP case fine. PD adds a 5th per-player control-mode entry ("PC controls") with a save-compatibility shim (written as an existing N64 mode so the save format never changes, overridden back to PC mode on read by config) to let *any* player be on mouse+keyboard, not just P1. Only relevant if "P1 on pad, P2 on keyboard" (or more than one keyboard player) is ever a real ask — bigger feature than anything currently planned; not worth a Dxx yet. + +## D224 — QoL gap (M-87, from a PD-PC-port survey): the N64 Rumble Pak is fully dropped instead of modernized. + +**QoL gap (M-87, from a PD-PC-port survey): the N64 Rumble Pak is fully dropped instead of modernized.** GE genuinely has a rumble subsystem (`src/motor.c`, `src/joy.c`) but the port's `osMotorInit/Start/Stop` (`port/src/libultra.c:1220-1223`) are all hard stubs — "no accessories on the PC," `osMotorStart`/`osMotorStop` return `-1` unconditionally, `osPfsFindFile`-family returns `PFS_ERR_NOPACK`. So every in-game rumble event (weapon recoil, explosions, etc.) computes and calls into a dead path. **PD's PC port wires the equivalent straight through to real gamepad rumble:** `inputRumbleSupported(idx)` checks `SDL_GameControllerHasRumble`/`SDL_JoystickIsHaptic` (with a Windows fallback: some pads report no haptics but rumble anyway), `inputRumble(idx, strength, time)` calls `SDL_GameControllerRumble()` scaled by a per-pad `RumbleScale` config value (options-menu slider, `Input.PadN.RumbleScale`), and `osPfsFindFile` reports a "Rumble Pak" present exactly when a real pad supports rumble (`libultra.c` — same "pretend the N64 accessory is there" pattern GE's port already uses for `osMemSize`/Expansion Pak, just applied to a real capability instead of faked). Cross-ref `QOL-INVENTORY.md` (folded into the existing "per-pad tuning" row). + +**Status (from §F table):** **DEPRIORITIZED (M-87, user call).** Gamepad-only — irrelevant to mouse/keyboard, which is the primary target for this next release; no keyboard/mouse play is affected by NOT doing this. Root cause + fix still valid whenever gamepad support becomes a priority (no `src/` game-logic touch: GE's `motor.c`/`joy.c` call sites already exist and already call the `osMotor*` shims; the fix is entirely in `port/src/libultra.c` + `input.c` — add `inputRumbleSupported`/`inputRumble` per the PD shape, wire `osMotorStart`/`osMotorStop` to them, add `Input.PadN.RumbleScale` config). **M-87 PD-legacy-survey addendum (`docs/dev/notes/PD-LEGACY-SURVEY.md` candidate 1, high confidence) — the D224 fix as originally stated is NOT sufficient by itself.** Two more upstream blockers sit before the stubbed `osMotorInit/Start/Stop` ever gets reached: (1) `port/src/libultra.c:1096-1098` sets `g_contStatus[i].status = 0` for every pad — `CONT_CARD_ON` is never set, and `src/joy.c:184` gates the *entire* rumble-pak init path on that bit, so `joyRumblePakInit()` never even calls `osPfsInit`. (2) `src/joy.c:186-190` only attempts `osMotorInit` if `osPfsInit`'s return is `PFS_ERR_ID_FATAL` or `PFS_ERR_DEVICE` — but the port's stub (`libultra.c:1214`) returns `PFS_ERR_NOPACK`, so motor init is never attempted even once (1) is fixed. PD's exact trick (`libultra.c:213-227,349-351`): set `CONT_CARD_ON` for connected pads, and make `osPfsInitPak()` return `PFS_ERR_DEVICE` specifically when the pad supports rumble. **Whenever D224 gets implemented, both of these must land alongside the `SDL_GameControllerRumble` wiring** or the game's state machine parks at `RUMBLEPAKINITSTATE_NOT_READY` forever and nothing audibly changes despite looking wired up correctly. + +## D225 — Dev-tooling QoL (M-87, user ask): a debug-build/env toggle that unlocks all missions + all cheats, for testing. + +**Dev-tooling QoL (M-87, user ask): a debug-build/env toggle that unlocks all missions + all cheats, for testing.** Root-caused a clean single choke point — **both** gates route through the same function: `bool fileGetIsCheatUnlocked(save_data *save, s32 cheat)` (`src/game/file2.c:391`) reads the save's `unlocked_cheats_1/2/3` bitfields and returns whether bit `cheat` is set. Mission-select lock (`src/game/file.c:59`, gates whether a briefing page's mission is selectable) and the cheat-menu availability check (`frontCheckIfCheatIsUnlocked`, `front.c:1009`, itself calling `fileGetIsCheatUnlocked` for the per-level `SP_LEVEL_*` cheat IDs) **both** call it — it's a pure, side-effect-free bitfield read (no save-data mutation), so short-circuiting it to always-true under a debug env var unlocks mission-select *and* the cheat menu in one change, matching exactly what was asked ("those two go a long way"). **Bonus, free once cheats unlock:** the ROM already contains real Rare-era developer cheats that are otherwise unreachable in normal play — `CHEAT_LINEMODE` (wireframe render — would make D222-style culling bugs trivial to see), `CHEAT_BONDPHASE`, `CHEAT_DEBUG_POS`, `CHEAT_DEBUG_UNK5` (`cheat.c` ~L687-707, `CHEAT_MASK_GLOBAL`) — worth trying once this lands, may be useful dev tools in their own right. + +**Status (from §F table):** **OPEN — root-caused, not implemented.** Plan: `#ifdef PORT`, env-gated (e.g. `GE_DEBUG_UNLOCKALL=1`, catalogue in `GE-ENV-PROBES.md` once added) short-circuit at the top of `fileGetIsCheatUnlocked` — `if (getenv-cached-flag) return TRUE;` before the bitfield read. Default off ⇒ zero behavior change for normal play; when set, purely a query-time override (save file itself is never touched, so it can't corrupt a save or leak into the shipped default).

Same function is also used by menus/options/multiplayer UI (`front.c`, `options.c`, `mpmenu.c`) — **do not scale generically**, those have their own layout at fixed screen fractions and D211 already established HUD anchors must stay put; scale only the 3 in-game HUD call sites named above, about their existing anchor (so bottom-left stays bottom-left, top stays top — same anchor-preserving principle as D211's HUD-static check). + +**Status (from §F table):** **OPEN — root cause / call sites identified, not designed or implemented.** Two viable directions: (a) a `#ifdef PORT` wrapper at just these 2-3 `bondview2.c` call sites that scales the emitted `gSPTextureRectangle` geometry (`xl/yl/xh/yh`) by a new `f32 portHudScale` (default 1.0 ⇒ byte-identical) while inversely scaling `dsdx/dsdy` to keep the same source glyph texels mapped onto the larger/smaller rect, re-anchored so the opposite edge (bottom for the lower-left block, top for dialogue) doesn't move; or (b) thread a scale parameter into `textRenderOutlined`/`textDrawGlyphQuad` itself, defaulted to 1.0 at every other call site. (a) is more surgical (matches the "don't touch shared menu text" constraint) but duplicates a little geometry math; (b) is more central but touches a much more widely shared function. No PD precedent found (PD's port has no equivalent HUD-scale option). F10 overlay slider candidate once implemented, alongside `Video.FovScale`. + +## D230 — In-level music quality: a bass instrument sounds corrupted on PC, correct on N64 reference (M-105, user reports; repro refined M-106). + +**In-level music quality: a bass instrument sounds corrupted on PC, correct on N64 reference (M-105, user reports; repro refined M-106).** Filed to give the post-D77 residual its own label — D77 (in-level music *absence*) is RESOLVED (PR #42, missing `return` in `sub_GAME_7F0C0BF0` zeroed the seqp volume on the only in-level trigger path), so "music doesn't play" claims in tracked docs are stale; what actually remains is this quality gap. **M-106 repro, deterministic (not intermittent):** Control's elevator track and its regular in-level track both carry the bad instrument throughout; Cavern's elevator track has it too; Runway's track is otherwise fine but the same instrument enters ~5–7s after the track starts and sounds bad from then on. User confirmed against original N64 reference audio that a bass instrument belongs there on Runway — this is **not** a wrong-instrument/wrong-bank selection (rules out the D77 trigger-path family and the seqp-volume fix's neighborhood); the instrument choice is correct, only its *sound* is wrong on PC. Determinism (same track, same spot, every time) points at a static decode/synthesis bug for this instrument's wavetable/ADPCM data — most likely low-frequency-specific (pitch-shift/downsample artifacting, a wrap/loop-point error, or a clipping/gain issue that only bites bass-range samples) — rather than a live mixing/voice-stealing issue (D147/D152/D202 family), which would be intermittent. The mixer layer and the trigger layer are both proven working by every track that sounds right, so the suspect neighborhood is the seq/instrument-bank decode path (`csplayer.c`/`synthesizer.c`, bank loading), not `port/` audio plumbing. + +**Status (from §F table):** **OPEN — static-analysis pass done (M-108), not runtime-confirmed.** Repro: Control (elevator + regular track, throughout), Cavern (elevator, throughout), Runway (~5–7s in). Traced the suspect neighborhood to the software ADPCM decoder in `port/src/mixer.c` — the PC replacement for the RSP's `aLoadADPCM`/`aADPCMdec` ucode ops (`csplayer.c`/`synthesizer.c` only emit ucode command lists; they don't decode samples themselves). Found two hardcoded assumptions that don't hold for the general ADPCM-book format: (1) `sAdpcmTable` (`mixer.c:174`) is declared `[8][2][8]`, hardcoding predictor `order=2`, but `order`/`npredictors` are per-instrument authored fields (`include/PR/libaudio.h` `ALADPCMBook.order`; `src/libultra/audio/load.c:428-429` computes `bookSize` from them) that the bank-relayout code (`port/src/romdata.c:718-736`) already handles generically — if this bass instrument's authored book uses `order != 2`, the 2-tap recursion at `mixer.c:223-240` would decode it wrong; (2) even at `order=2`, `aLoadADPCMImpl` (`mixer.c:177-192`) silently truncates any book over 256 bytes (`mixer.c:183`, `npredictors > 8`), while the decode loop's 4-bit predictor-select nibble (`mixer.c:219`) can legitimately address up to 16 rows — an instrument with `npredictors > 8` would read truncated/garbage rows for some frames. **Caveat weakening confidence:** N64 SDK ADPCM in practice is conventionally always `order=2` (the RSP ucode's own decode algorithm is essentially fixed to a 2-tap recursion industry-wide), so candidate (1) may not apply to a real N64 title's data; candidate (2) (`npredictors > 8`) is the more plausible of the two absent contrary evidence. Not confirmed against GE's actual ROM-authored book data (no live capture taken this pass). Next: extend the existing `GE_MIXERTRACE=1` trace's `[LOADADPCM]` line (`mixer.c:187`, already logs `count` — `count/16 = order*npredictors`) to flag any book where `count > 256` (proves truncation) during a Control run, and correlate the anomalous book to its channel/instrument via `seqplayer.c:1120`'s program-change. If no anomaly shows, this whole neighborhood is likely a dead end and the next suspect is the resample (`mixer.c:295-341`) or envelope/gain (`mixer.c:379+`) paths for bass-range-specific behavior. **M-120 (local-Qwen triage dispatch): a third hypothesis proposed and CHECKED, RULED OUT.** The dispatched read-only pass proposed that `afFixupBook`'s `port/src/romdata.c:733-737` conversion of the ADPCM book coefficients (BE ROM → LE host, via `afRd16`/`afWr16`) is backwards and should stay big-endian. Verified against the actual code and disproven: (1) that conversion is the identical BE→LE pattern used for every other field in the same function (`order`/`npredictors` two lines above) and in the sibling `afFixupAdpcmLoop`'s ADPCM state array a few lines down — not something special-cased for this one book; (2) `port/src/mixer.c`'s `aLoadADPCMImpl` does a raw `memcpy` of the already-converted book straight into a host-native `s16[8][2][8]` table with no further byte-swap, consistent with the coefficients being intentionally pre-converted to host order; (3) decisively, `afFixupBook` is one shared code path applied uniformly to every ADPCM book in the game — if this conversion were actually backwards, every ADPCM-encoded sound would decode wrong, not one bass instrument on three tracks, and the vast majority of the game's audio is confirmed correct. Do not re-propose this specific byte-order theory without new evidence; the standing M-108 leads above (predictor-count truncation / `order` mismatch) remain the live ones. **FIXED (M-121, v0.2.0 finalization) — root cause was a plain byte-order bug in a corner neither M-108 nor M-120 looked at: RAW16 wavetables.** Offline decode of the local NTSC ROM's instrument bank found exactly two `AL_RAW16_WAVE` (type 1) wavetables — instruments 2 and 51, both sharing base 0x2118 / len 790 in the `_instrumentstbl` segment — which decode as a clean ~110 Hz soft-attack bass synth sample when read as **big-endian** s16. That is the missing bass instrument on Control/Cavern/Runway. On N64 the CPU reads those bytes BE, so it plays fine there; on PC the mixer's resampler (`port/src/mixer.c` `alRaw16Pull` path) consumes host-native (little-endian) s16, so every sample arrives byte-swapped — a deterministic per-instrument corruption, exactly matching the M-106 repro (and explaining why every ADPCM-based instrument in the game sounds right: nibble data is byte-order agnostic). Both M-108 candidates are moot — every ADPCM book in both bank trees (scanned offline from the ROM) is `order=2, npredictors∈{1,4}`, so neither the `[8][2][8]` shape nor the 256-byte truncation can ever bite GE's data. **Fix (port-only, D55 in-place-fixup idiom):** `romdataFinishCartMap()` (`port/src/romdata.c`) now walks both bank trees (SFX + instruments; same ALBankFile layout as `romdataFixupAudioBank`) and bswap16s each RAW16 wavetable's `[tbl+base, +len)` range in place in the cart map — where the sample data lives for the mixer (`alBnkfNew()` points at the tbl segments directly; only the bank structs are re-laid out, D37). Shared ranges are deduped (swapping twice would undo the swap); every read is bounds-checked against the ROM size. Startup log: `romdataInit: D230 byte-swapped 1 RAW16 wavetable range(s) in place` (one range: the two instruments share the sample data). Byte-level verification done (BE decode of the ROM range = clean tone; post-swap LE decode identical by construction); **owes a by-ear pass** on Control (elevator + level track), Cavern elevator, and Runway ~5–7 s in. + +## D218 — Wide FOV exposes the per-level draw-distance / fog boundary — "blue artifacting" down long peripheral sightlines (M-84, user QA on the D211 FOV slider). + +**Wide FOV exposes the per-level draw-distance / fog boundary — "blue artifacting" down long peripheral sightlines (M-84, user QA on the D211 FOV slider).** BUNKER→**Dam main tunnel** at `FovScale` ~150: geometry / backdrop past the level's fog-end distance shows at the widened frustum edges (blue = Dam's fog tint). Not a render bug — `fogLoadCurrentEnvironment` (`bgfog.c:305`) does `viSetZRange(Visibility.BlendMultiplier, Visibility.FarFog)`, so **`Visibility.FarFog` is both the far clip plane and the fog-saturation distance**; levels tune it for the stock ~60° FOV. + +**Status (from §F table):** **Logged (M-84), fix proposed + parked.** Plan: `Video.DrawDistance` (percent, 100–400, default 100 ⇒ no-op) `#ifdef PORT` multiplier on `FarFog` at `bgfog.c:305` (+ the direct `arg0->Visibility.FarFog` reads just below, so fog stays consistent) plus `Video.DrawDistanceAutoFov` (0/1, default 1 — couples draw distance to `FovScale` unless `DrawDistance` is set explicitly). Clamp effective multiplier ≲2.5× (small znear ⇒ far-field z-fighting risk). **M-87: user confirms still occurring** at high FOV, and — reversing the earlier "not implemented by user request" — **now wants `Video.DrawDistance` implemented as a real QoL feature**, plus scope it to cover **LOD/detail-distance in general**, not just the fog/far-clip boundary this row root-caused. Open question for that broader ask: does GE have a *separate* geometry/object LOD-swap or draw-culling distance mechanism (distinct from `Visibility.FarFog`) worth exposing too, or is fog-distance the only meaningful "how far can you see" knob in this engine? Check for a per-object visibility-radius / simple-model-swap system before assuming `FarFog` is the whole story. **FIXED as designed, awaiting visual verification (M-121).** Implemented exactly the parked plan: `f32 portDrawDistanceMultiplier(void)` (`port/src/video.c`) — an explicit `Video.DrawDistance != 100` wins outright, otherwise `Video.DrawDistanceAutoFov` (default on) couples the multiplier 1:1 to `Video.FovScale`, clamped to `[1.0, 2.5]` (never shrinks draw distance; the 2.5x ceiling is the finding's own far-field z-fighting caution). Applied in `fogLoadCurrentEnvironment` (`bgfog.c`) to a new local (`scaledFarFog`) used at *both* the `viSetZRange` far-clip call and the `g_CurFogDetails.scaled_far_fog_dist` fog-blend read just below it, so the clip plane and the fog math stay consistent per the original plan's own note — the level's `EnvironmentRecord` itself is never mutated (it's shared/reloaded, not a per-frame copy). Both new config keys added to the F10 overlay (`Video.DrawDistance` slider, `Video.DrawDistanceAutoFov` toggle) alongside the existing `FovScale` row. Identity at both defaults (`DrawDistance=100`, `FovScale=100` ⇒ `portFovScale==1.0f`) by construction. **Broader LOD-swap question from M-87 ANSWERED — yes, and now exposed too (same session, M-121 continued).** `src/game/model.c` has a real, distinct geometry-LOD system: `MODELNODE_OPCODE_LOD` nodes whose children are shown/hidden per-frame by `modelUpdateDistanceRelations()` testing a view-space `distance` (scaled by `getPlayer_c_lodscalez()`, itself now FOV-consistent per this session's D222 fix) against each node's `MinDistance`/`MaxDistance` — a genuine detail-swap mechanism, separate from the fog-visibility-fade this row already fixed. It even has an existing ground-truth multiplier hook, `g_ModelDistanceScale`, already used transiently by the game itself (`chr.c`'s 0.3125f close-up override, `front.c`/`title.c`'s menu-model `modelSetDistanceDisabled`). Rather than write to that shared global (would fight those existing overrides), added a second, composed multiplier at the same call site: `f32 portLodDistanceMultiplier(void)` (`port/src/video.c`), driven by new `Video.LodDistance` (percent, 25-400, default 100) and `Video.LodDistanceAutoFov` (**default OFF**, unlike `DrawDistanceAutoFov` — this is meant as a standalone performance lever the user can pull *down*, not something that silently adds cost as FovScale widens) — `distance *= portLodDistanceMultiplier()`, inverse-scaled so `LodDistance=200` keeps full detail twice as far (more cost) and `LodDistance=50` drops to the lower LOD twice as soon (less cost). Both new keys in the F10 overlay alongside `DrawDistance`. Identity at `LodDistance=100`. Rebuilt clean, crash-free at `LodDistance=40` (aggressive) on Dam and at defaults on bunker1. **M-121 live playtest, iterated to a working state.** Two real issues found and fixed while testing live on Dam with the user: (1) **regression** — the D222 fix (above) correctly widened `c_lodscalez` for the screen-edge cull planes, but that same value is *also* read directly by `propobj.c`'s `chrobjFogVisRangeRelated()`/`sub_GAME_7F054C58()` (the character/prop fog-visibility-fade cutoff) — uncompensated, this made guards fade/disappear *sooner* at wide FOV than before D222, the opposite of the intent. Fixed by dividing that same `c_lodscalez` reading by `portDrawDistanceMultiplier()` at both call sites (`#ifdef PORT`), so the "how far can you see" question these two share is answered consistently. (2) **tuning** — a straight 1:1 `Video.FovScale` auto-coupling on `portDrawDistanceMultiplier()` was not aggressive enough; live-tested up twice (1x → 2x → 4x `FovScale`, clamp ceiling raised 2.5x → 4.0x → 6.0x each time) before guards held up and the Dam tunnel's blue-glow artifact receded to the user's satisfaction. Re-verified end-to-end that the fog *ramp* itself (not just the far-clip cutoff) scales with the multiplier — `g_ScaledFarFogIntensity`/`scaled_far_fog_dist` both derive from the same scaled far value — so if a similar artifact resurfaces on another level, the multiplier magnitude or a level-specific tunnel-length edge case are the first things to check, not this math. **User confirms this is good for now.** All three (D222 cull fix, D218 draw-distance + fog-visibility-fade fix, D249 LOD-distance) verified crash-free and landing in the same PR. + +## D220 — 1P muzzle flash position shifts upward at higher `Video.FovScale` (M-87, user QA, Jungle/M16). + +**1P muzzle flash position shifts upward at higher `Video.FovScale` (M-87, user QA, Jungle/M16).** Likely shares D211's noted residual: the viewmodel draws through `c_perspfovy`/unscaled fovy while the world view is FovScale-scaled (`fr.c:737`), so a flash sprite anchored to viewmodel-space vs. screen-space math can drift as the two diverge more at higher scale. + +**Status (from §F table):** **ANALYZED (M-91) — the suspected unscaled-viewmodel root does NOT hold; this is correct perspective behavior, likely cosmetic/QoL.** The 1P hand + flash are model nodes in ONE gun DL (`gunfire.c` builds `rwmtx[1..4]` for hammer/flash/billboard nodes) drawn through the single per-frame projection from `viSetupCurrentPlayerView` — which IS FovScale-scaled on PC. So the flash and the muzzle it attaches to share projection and matrix chain: their relative position is geometrically preserved. What moves is the whole camera-anchored viewmodel: under perspective, screen offset from center ∝ 1/tan(fovy/2), so widening the FOV migrates every camera-space point (gun body included) toward screen center — a muzzle sitting slightly below/right of center visibly drifts up-left at FovScale 150. Same family as the M-85 accepted "viewmodel scales down, stays bottom-right anchored". `c_perspfovy`/`currentPlayerSetCameraScale` do stay unscaled (the D211 note) but that feeds frustum-cull/screen↔world math (→ D222), not the flash's render path. **Disposition: human call** — if it bothers at high FovScale, the fix is a QoL viewmodel re-anchor/scale-at-FOV (VIEWMODEL-RESEARCH.md family), not a fidelity bug; no game-logic change either way. Optional headless confirm: Jungle M16 fire at FovScale 100 vs 150, measure flash centroid vs muzzle in PPM pairs (expected: both shift toward center together). + +## D235 — Wrong textures load after dying/restarting a level — not Facility-specific, seen on multiple levels (M-106, user QA report; clarified same session). + +**Wrong textures load after dying/restarting a level — not Facility-specific, seen on multiple levels (M-106, user QA report; clarified same session).** Original report ("Facility: wrong textures now") read as a build regression; user clarified the actual trigger is **death/restart** (or a similar level-reload path), and it has recurred on other levels too — this is a state-leak on level re-entry, not a one-level texture-decode bug and likely not caused by #47/#49 at all. Prime suspect: the texture pool / CI-cache (D217/D228 neighbourhood) not being fully reset between a level teardown and its reload — a stale arena base, a leftover palette-cache entry keyed by an address that gets reused with different content, or a texpool index not rewound — surfacing as "wrong texture" only after the reload path runs, never on a fresh level boot. Logged in `GRAPHICS-BACKLOG.md`. + +**Status (from §F table):** OPEN — needs: does it repro on a *fresh* level boot (rules out reload-state) vs only after death/restart (confirms it); which surfaces; a screenshot. **M-108 static-analysis pass: the leading "stale CI-cache not reset on restart" hypothesis is likely REFUTED, don't re-propose it as-is.** The theory was that `g_TexCacheItems`/`g_TexCacheCount` (`src/game/image.c:38-40`, cleared only in `set_mt_tex_alloc()`, `src/game/initmttex.c:8`) survives a death/restart because the restart path skips `set_mt_tex_alloc`. But tracing the actual call graph: `set_mt_tex_alloc()` runs inside `lvlStageLoad()` (`src/game/lv.c:369`), which has exactly **one** call site (`src/boss.c:485`) inside `bossMainloop`'s outer `while (!done)` loop; that loop re-runs on *every* stage transition, driven by `g_StageNum = g_MainStageNum` (`boss.c:693`) which is set by `bossSetLoadedStage()` (`boss.c:722`) — the same function the front-end's level-select/continue path calls (`front.c:6947`). Nothing in this call graph is level-select-specific vs. restart-specific; both look like they go through the identical full reload (including the `set_mt_tex_alloc` cache reset). Have not yet found the actual death/restart trigger's call site to be 100% certain it doesn't have its own bypass, so this isn't fully closed out — but the single-reload-path structure makes the "cache survives restart" mechanism unlikely as stated. Next: find the actual death-handler call site (search for where a life/continue/retry decision is made, likely `chr.c`/a game-state machine, not yet located) and confirm whether it calls `bossSetLoadedStage`/goes through `bossMainloop`'s reload path same as normal transitions, or has a distinct lighter-weight path — if it's the same path, the real D235 mechanism is still unknown and this CI-cache theory should be dropped. + +## D236 — Surface 1: 2D billboard trees render as a wall/sheet of tree texture instead of discrete camera-facing tree sprites (M-106, user QA report). + +**Surface 1: 2D billboard trees render as a wall/sheet of tree texture instead of discrete camera-facing tree sprites (M-106, user QA report).** Eight passes so far (D265, D266–D270, D271, D272, D273, D274, D275–D276).

Weapon fire re-triggers its SFX through `bondwalkItemGetSoundTriggerRate()`/`bondwalkItemGetSound()`, gated on `g_GlobalTimer` (`src/game/gunfire.c:3246-3286`: `handptr->field_A4C = bondwalkItemGetSoundTriggerRate(var_s1) + g_GlobalTimer`), alternating between two per-hand `ALSoundState` slots (`audioHandle`/`field_A48`, same block) so a fast-firing weapon's report can overlap itself once before being retriggered. `g_GlobalTimer` advances by `g_ClockTimer = speedgraphframes` every tick (`src/game/lv.c:1023,1037`), and `speedgraphframes` is set from `deltaFrames` in `updateFrameCounters()` (`src/game/frametiming.c:64-76`) — the exact tick-delta plumbing already investigated (and partly fixed) under **D155** (catch-up-spiral clamp, same file), **D186** (`Video.FpsCap` sim-coupling clamp), **D193/D209** (AI-locomotion timing keystone — D209 the actual root cause, a 64-bit union-aliasing bug, now fixed and merged), and **D204** (audio pipeline running ~2% below real time forever, fixed by padding silence at the DAC). Since D209 and D204 both merged before this report, the SFX-cadence complaint is either (a) a genuinely distinct, audio-specific residual downstream of those fixes — e.g. a mismatch between the sim-tick-gated *trigger* (above) and the software mixer's own playback clock (`port/src/audio.c:93,155,221-222` — the synth produces samples at a measured ~21600/s against the 22050 Hz output device, the same gap D204 had to compensate for elsewhere) that specifically desyncs how *often* a shot's sample starts rather than the absolute wall-clock rate D204 measured, or (b) a stale pre-D209/pre-D204 build report. Per-weapon rate constants (`AutomaticFiringRate`/`SingleFiringRate`/`SoundTriggerRate`, `src/game/gun.h:60-82`, values in `assets/obseg/gun/*/gunWeaponStat.inc.c`) are plain compiled C literals, not ROM-serialized data, so no pointer-width/ABI reconciliation issue applies here. + +**Status (from §F table):** **OPEN — not root-caused; static call-site tracing only, no runtime verification possible in this environment.** Confidence LOW-MEDIUM that this is a *new* bug distinct from the D155/D186/D193/D204/D209 timing-keystone family (all of which gate the identical `deltaFrames→speedgraphframes→g_ClockTimer→g_GlobalTimer` chain this SFX trigger consumes). Raise confidence by: (1) confirming the user's build/commit postdates the D209 merge; (2) a `GE_AUDIOTRACE`-style capture logging the tick (`g_GlobalTimer`) and/or wall-clock timestamp of consecutive same-weapon fire-SFX requests during sustained auto-fire (AK47/Klobb, `AutomaticFiringRate=0x03`), diffed against the weapon's rate constant and against N64 reference footage's frame-count between shots. + +## D241 — Player gunshot SFX goes silent under some conditions — reported on Bunker with the alarm sounding, "or some other factor" — but only for PP7 and AK47, Klobb… + +**Player gunshot SFX goes silent under some conditions — reported on Bunker with the alarm sounding, "or some other factor" — but only for PP7 and AK47, Klobb unaffected (M-106, user QA report, concrete repro).** This is very likely **D207 finally reproduced.** D207 (M-77) root-caused that GE's SFX player has a hard **8-voice cap** (`MUSIC_SFX_SEQ_MAYBE_MAX_SOUNDS`, `src/music.c:76`) and that D206's fix made the alarm klaxon (`ALARM3_SFX`=163, triggered from `handle_alarm_gas_timer_calldamage()`, `src/game/propobj.c:14457`) a genuine **infinite ADPCM loop** that now legitimately occupies one of those 8 voices for the alarm's whole duration; the manual preemption scan (`snd.c:~347-392`) refuses to steal any *owned* LOOPED voice (the M-65 carve-out only exempts *ownerless* loops), so once 8/8 voices are held, a new one-shot request is silently dropped via `sndDisposeSound` (`snd.c:391`). D207's own M-77b session built a `GE_FORCEALARM=1` BUNKER1 harness and could **not** reproduce audible drops (`[D207-DROP]=0`), and explicitly left as "owed": *"needs a real repro from the user: which level, which weapon/situation."* This report supplies exactly that (Bunker, alarm). **Investigated why PP7/AK47 and not Klobb, inconclusive at the code level:** Klobb (`ITEM_SKORPION` — confirmed GE's internal name for the Klobb via `src/game/player.c:576`, `skorpion_stats` in `assets/obseg/gun/skorpion/gunWeaponStat.inc.c`) and AK47 (`ak47_stats`, `assets/obseg/gun/ak47/gunWeaponStat.inc.c`) share the **same** `AutomaticFiringRate=0x03` (fast auto), while PP7 (`wppk_stats`, `assets/obseg/gun/wppk/gunWeaponStat.inc.c`) is semi-auto only (`AutomaticFiringRate=0xFF`) — so a naive "fires faster ⇒ more self-inflicted voice contention" theory does not cleanly explain grouping PP7 with AK47 against Klobb. All three weapons' fire SFX (`GUN_B1_MGUN3_3_SFX`=Klobb, `GUN_B2_HEAVY_SFX`=PP7, `GUN_B4_BOLTACTION_SFX`=AK47 — `src/bondconstants.h:2277-2280`) go through the identical one-shot, priority-0x40 `sndPlaySfx` path (`gunfire.c:3246-3286`); no per-weapon distinction exists in the trigger or priority *code*. A real distinction, if one exists, most likely lives in the **sample bank data itself** (per-sample envelope/decay length — a longer-tailed sample stays `PLAYING` and stealable/held longer, changing its odds in the preemption scan) — that data is ROM-derived binary content, not inspectable without the extracted ROM (`./data/`, absent in this worktree). Confirmed the voice-allocation/preemption code is unmodified `src/snd.c` game logic, not a `port/` mixer bug: `port/src/mixer.c`/`port/src/audio.c` implement DSP synthesis and device output only (per D199), with no SDL `Mix_*`-style channel-priority layer in the port to have introduced a new bug. Per AGENTS.md non-negotiable #2, any real fix belongs in D207's already-designed (reverted, M-77b) last-resort LOOPED-preemption pass in `snd.c`, not in `port/`. + +**Status (from §F table):** **OPEN — not newly root-caused; high confidence this is D207 reproduced, not an independent bug.** Recommend folding this repro into D207 (or closing D241 as a duplicate once D207 is reopened) rather than tracking separately. Next: re-run M-77's `GE_FORCEALARM=1` harness on `-level_09` with scripted PP7 and AK47 fire (not just generic fire) against Klobb as a control, watching `g_sndAllocatedVoicesCount` / the (currently reverted) `[D207-DROP]` counters to see whether the 8-cap is actually hit for two of the three weapons and not the third — or whether it is really the sample-envelope-length distinction above.

Each individual replay's own advance is driven purely by animation/timer state (`bondview2.c:1467-1490`): the `g_CameraAfterCinema` flag that `bondviewAdvanceCameraMode()` acts on is set automatically once `modelGetAnimFrame(bodyModel) >= modelGetAnimEndFrame(bodyModel)`, or after a `camera_transition_timer >= 180.0f` tick-timeout fallback when there is no body model — **no button check in that branch; fully automatic.** **The button-press the user is hitting is a real, intentional N64 skip-ahead shortcut, not a port-added gate:** the same code block (`bondview2.c:1483-1489`) *also* fires the identical advance immediately on `(buttons & ~oldbuttons & (CONT_A | B_BUTTON | Z_TRIG | START_BUTTON))` whenever `bonddead && redbloodfinished && deathanimfinished` — i.e. on real N64 hardware, pressing A/B/Z/Start at any point during a death replay skips straight to the end, by design. **On the port, LMB (mouse fire) is mapped to `GE_CONT_G`, which is Z_TRIG** (`port/src/input.c:664-665`: `(mb & SDL_BUTTON(SDL_BUTTON_LEFT)) ... button \|= GE_CONT_G`; binding table `input.c:351`: `{"Z",GE_CONT_G}`) — exactly one of the four original skip buttons. So an LMB click during the death sequence is GE's own original cutscene-skip input, faithfully wired through the port's control remap, not a port-invented "click to continue" prompt. **What this investigation could not determine** (no build/runtime access in this worktree): whether the *automatic*, no-input path actually completes on PC in a reasonable time. `camera_transition_timer` accumulates via `g_GlobalTimerDelta` (`bondview2.c:1470,1493`), which is set from the same `g_ClockTimer`/`speedgraphframes`/`deltaFrames` chain flagged in D240 above and investigated under D155/D186/D193/D204/D209 — if any residual in that chain stalls or mis-scales specifically in this state, the auto-advance could take far longer on PC than on N64 (or effectively never complete before the player gives up and clicks), which would make an LMB click *feel* mandatory even though the ground-truth logic never requires one. + +**Status (from §F table):** **NOT A PORT-LOGIC BUG as far as static analysis can tell.** Confidence HIGH that the LMB-click skip path is faithful original behavior (Z_TRIG-mapped, exists unmodified in `bondview2.c`), not a defect to remove. Confidence LOW (untested) on whether the no-click automatic path is actually healthy on PC. Needs a human playtest: die, then **deliberately touch no input** during the death sequence and time whether/how long until the mission-failed screen appears on its own. If it never arrives without a click, the real bug is a `g_GlobalTimerDelta`/`camera_transition_timer` stall in the D240 clock family — cross-reference D240 — not a wrongly-added input gate, so there is still no `#ifdef PORT` skip-gate to remove per AGENTS.md #2. No runtime verification possible in this environment (no ROM/display). + +## D243 — Dam end-of-level cutscene (the abseil/bungee sequence, D148/D160's subject): the camera violently shakes/"spazzes" during each of the scripted camera-angle… + +**Dam end-of-level cutscene (the abseil/bungee sequence, D148/D160's subject): the camera violently shakes/"spazzes" during each of the scripted camera-angle cuts (M-107, live `GE_D160=1` trace, two interactive `-level_33` runs + one fresh-save normal-progression run).** **First, corrects D160's own premise: the cutscene is NOT skipped on the current build.** Both debug-loaded runs show exactly the AI-script-scripted sequence firing: `bondviewSetCameraMode(7)` (`CAMERAMODE_POSEND`, the cutscene camera-lock state) called 2-3 times, matching `ai_17`'s three `camera_switch` commands in `UsetupdamZ.c`'s abseil ailist (`assets/obseg/setup/UsetupdamZ.c:2656`+), followed by `bossReturnTitleStage`. So D160's original (b)/(c) hypotheses (AI trigger never fires / puppet renders invisibly) are **refuted on this build** — the mechanism runs; what's broken is what it renders. **Root cause candidate, directly observed:** right in the camera-cut window, fast3d's D146 catch-all (`port/fast3d/gfx_pc.cpp:3037`, "unknown GBI opcode … ending DL") fired a tight burst — same 4 memory addresses repeating every frame for ~10 frames, then clean — with payload bytes `0xfafbfbfcfcfbfdfc`/`0xfcfafbfbfafbfafb`: a **freed/uninitialized-memory fill pattern**, not real GBI commands. This reads as a stale-pointer display-list read, not a decode bug — some segment/scene buffer backing the outgoing camera shot's geometry got freed or recycled while a still-in-flight display list (queued ahead in the port's double-buffered render pipeline — see D134's "pendingGfx" note, `port/src/libultra.c:733-746`, on how many frames of latency the sched round-trip can carry) still referenced it. **Independent evidence of a race, not a fixed-order bug:** the two `-level_33` debug-load runs show the camera_switch(7) calls landing in a *different order relative to* `bossReturnTitleStage` between runs (run 1: three switches, then the stage-return call; run 2: two switches, the stage-return call, *then* a third switch arriving after) — and the D146 corruption burst appeared in run 1 but not run 2 at all, non-deterministically. That pattern (symptom present/absent, call order shuffling) is the signature of a genuine timing race between the AI-list's cutscene commands and the level-exit/report-transition code, not a deterministic logic bug. **User-confirmed on real (non-debug-boot) play, not just the debug harness:** a fresh-save normal playthrough into Dam still hit the camera glitch on this same cutscene — ruling out "artifact of the `-level_33` debug boot" for this specific symptom (unlike the secondary "no report screen, straight to file-select" symptom seen only on the debug-loaded runs, which did NOT reproduce on the fresh-save run and is therefore most likely a `-level_N` debug-boot artifact per the D190 precedent, not filed as its own bug here). + +**Status (from §F table):** **OPEN — M-109 re-analysis of the same session's raw logs corrects the timing/pattern claims above; the D134/pendingGfx race hypothesis is likely wrong.** Confidence MEDIUM on the correction, LOW-MEDIUM on the new lead. Re-reading `data/playtest_d160.log`/`_run2.log` at the `g_framesRendered` level (not just grepping for `D146`) shows the D146 burst fires **~1600-3900 frames (tens of real seconds) *after*** `bossReturnTitleStage`/the `camera_switch(7)` calls, not during them, in **both** runs — "right in the camera-cut window" and "run 1 only" are both wrong as stated above. This also weakens the D134/`pendingGfx` citation: `osSpTaskStartGo` runs `gfx_run()` synchronously and inline (`port/src/libultra.c:1232-1258`), so nothing from the cutscene's own DL submission is still in flight by the time any teardown code runs — the port doesn't have the async-RSP race the hypothesis above assumes. **New lead:** whatever screen renders in that multi-thousand-frame gap after mission-complete is the more likely site — probably `MENU_MISSION_COMPLETE` (`front.c:7267`, `constructor_menu0D_missioncomplete`) or an adjacent briefing/file-select screen in that chain, same general class as D75 (front-end model absence) / D141 (menu bad-pointer bug), not a cutscene-render race. Of the 4 repeating fault addresses, 3 read as literal zero words and only 1 matches the `0xfafbfbfc…` pattern, arguing against a deliberate poison-fill (none found anywhere in `port/`) and for either genuinely-unwritten memory or a decode landing inside unrelated valid data. Next: an env-gated `front.c` menu-transition trace (`MENU_*` id + `g_framesRendered` on every transition after `bossReturnTitleStage`) plus a `GE_PCDUMP` window over frames ~4500-8000 (not the camera-cut window) to name the exact screen/segment. Cross-ref D160 (this supersedes its stale "cutscene skipped" framing with a "cutscene renders corrupted" one, now further corrected to "corruption isn't in the cutscene render at all") and D173 (Cradle's Bond-floating/spinning cutscene bug — same subsystem family, unconfirmed shared root cause). **M-120: the `GE_D243` trace above was BUILT (statically, i.e. written) on branch `investigate/d243-cutscene-race` (`764a1f26`, pushed, not merged) — `src/game/front.c` only, `#ifdef PORT`, logs the target `MENU_*` name + a local per-tick counter on every `menu_init()` state transition. NOT build-verified: two independent sessions (the dispatched subagent, then this session re-verifying in a fresh worktree) both hit the same reproducible failure — `cmake`'s C-compiler ABI check fails with "Cannot create temporary file in C:\Windows\: Permission denied" when gcc is invoked *through* CMake/ninja, even though a bare `gcc -c` invocation from the same shell, same session, succeeds and correctly resolves its temp dir to `%TEMP%`. This is a genuine, reproducible environment issue distinct from the diff's content (static review of the diff found nothing wrong: enum cases all verified to exist in `bondconstants.h`, brace/`#ifdef` balance checked, follows the existing `GE_D160`/`GE_D178` env-gated trace idiom used elsewhere in the same file) — worth a session with a working toolchain investigating the CMake/ninja-vs-bare-gcc environment discrepancy itself as its own item, separate from D243. Next: build `investigate/d243-cutscene-race` on a session where `./build-pc.sh` actually completes, then run the `-level_33` Dam repro with `GE_D243=1` (and the existing `GE_D160`/`GE_PCDUMP` mechanisms) to correlate the trace against the D146 burst's frame range. **M-141: the M-120 toolchain blocker is EXPLAINED and worked around, GE_D243 is now build-verified.** The "Cannot create temporary file in C:\Windows\" failure isn't specific to CMake/ninja vs. bare `gcc -c` — it's this Claude Code session's `Bash` tool shell (Git-for-Windows Bash, not a real MSYS2 MINGW64 window) not exposing a usable `TMP`/`TEMP` to child processes the way an interactive MSYS2 shell does; a bare `gcc -c` from the same shell happened to not hit the temp-file path M-120 tested, which is why it looked clean while the full build wasn't. Fix: explicitly `export TMP=... TEMP=...` (Windows-style path) alongside the already-known `PATH=/c/msys64/mingw64/bin:/c/msys64/usr/bin:$PATH` fix, both before invoking `./build-pc.sh`/`ninja`/`cmake` — now also recorded in `porting-notes.md` §E as a general session-start gotcha, not just a D243-specific note. Cherry-picked the `GE_D243` trace commit (`764a1f26`) cleanly onto `release/v0.3.0` (branch `investigate/d243-fresh`), fixed one thing the original diff got wrong per this project's own D250 rule (`menu_init()` runs ~once/frame during front-end states — the diff's three `getenv("GE_D243")` calls were uncached; now a single cached `static int s_d243` check), and confirmed it builds clean. **Smoke-tested, not fully exercised:** a bare `-level_33` boot runs 1100+ frames with zero crashes and (correctly) zero `D243:` log lines — bare `-level_XX` skips the front end entirely (per this doc's own M-24-era note), so `menu_init()` never runs; this only proves the probe doesn't regress normal boot, not that it captures anything useful yet. **Still blocked on the same thing M-107/M-109/M-120 all were: an actual interactive playthrough** (main menu → Dam → abseil cutscene → mission-complete → whatever screen the D146 burst fires on, ~1600-3900 frames later) with both `GE_D243=1` and `GE_D160=1` set, which needs a human with input, not available in this session. **Possible connection to D173 worth checking in that same playthrough** (per user, M-141): D173 (floating/spinning Bond puppet in cutscenes, e.g. Cradle/Trevelyan) and D243 (stale-memory DL read some seconds after a cutscene-driven `bossReturnTitleStage`) both sit in the scripted-cutscene/level-transition neighborhood and both ultimately touch "Bond's (or a puppet's) in-world model" — no code-level link found this session (D173's own M-106 pass already ruled out the two most likely struct-aliasing sites, and D243's mechanism looks like a stale/freed buffer read in a *different* subsystem, front-end/menu memory rather than a chr/puppet transform), so treat this as an unconfirmed hypothesis to keep in mind while capturing the next live trace, not an established shared root cause. **Steam Deck playtest confirmation, same M-141 session** — user independently reported "cutscene at end of dam level is badly glitched" without prompting, matching this row's own "camera violently shakes" symptom exactly. Second independent confirmation this is real and reproducible, not a one-off; still needs the interactive `GE_D243=1`+`GE_D160=1` capture this row already calls for. + +## D244 — Self-hosted CI runner (`corpyvt6agent01`) link failure: `undefined reference to 'objectiveGetStatus_WEAK'` (2026-09-12, first-ever build attempt on the… + +**Self-hosted CI runner (`corpyvt6agent01`) link failure: `undefined reference to 'objectiveGetStatus_WEAK'` (2026-09-12, first-ever build attempt on the reinstalled box, run `34707798707`).** `src/game/objective_status.c:162` uses `#pragma weak objectiveGetStatus_WEAK = get_status_of_objective` (a decomp ground-truth alias, referenced 2-arg from `chrai.c:2538` — comment calls it "horrible hack to get ai matching"). The box's `g++`/`ld` reported as `x86_64-w64-mingw32/16.1.0`; a minimal local repro of the identical `#pragma weak` cross-TU function alias **links cleanly** on this session's own machine (`mingw-w64-x86_64-gcc 16.2.0-3`, `binutils 2.47-3`). Not a game-logic bug (the alias is unmodified decomp code, ground truth) and not a CMakeLists/link-flag issue (no `--gc-sections`/LTO in play) — the leading, unverified explanation is the self-hosted box's MSYS2 packages predate a PE/COFF weak-external fix or behavior change versus current MSYS2, consistent with rollout step 2's earlier finding that the box's mingw64 package set was stale/incomplete at initial setup. + +**Status (from §F table):** **OPEN, not yet fixed.** Next: on the box, `pacman -Syu` (or at minimum `pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-binutils`) to bring the toolchain current, then re-dispatch `selfhosted.yml`. If updating doesn't clear it, the fallback is a narrow `#ifdef PORT` replacement of the alias with an explicit thin wrapper function in `objective_status.c` (ABI-preserving, no logic change) — but try the toolchain update first since the local repro suggests this is a version/environment gap, not a fundamental PE/COFF limitation. + +## D270 — Backfilled (M-132) — this label was never given its own row; only code comments and the HANDOFF archive documented it. + +**Backfilled (M-132) — this label was never given its own row; only code comments and the HANDOFF archive documented it.** D236 wall, between-pass instrumentation toolkit for the fog hypothesis (D269 ranked suspect #1) and general A/B isolation: `gfx_sp_tri1` per-vertex fog min/max attribution; `GE_D270SKIP`/`GE_D270SKIPOML`/`GE_D270KEEPOML`/`GE_D270KILLALL` (drop-by-oml/fmt A/B rules); `GE_D270PIX` (single-pixel draw-order attribution); `GE_D270FOG` (per-frame fog-color-change log); and the `GE_TEXRAW` dump cap raise 400→600 to reach the wall cards' upload index.

Water draws through the same port path: `src/game/sky.c` water block (~905–956) — `texSelect(&skywaterimages[WaterImageId])` + `sub_GAME_7F09343C` (two-texunit cross-fade; both tiles re-declared RGBA/16b @ tmem 0, the draw D229 fixed) then a `skyRenderTri` fan over `sp274[]` under `skyPortBeginFan(sp274, s1, FALSE)` — and **the `FALSE` is a documented, deliberate tolerance of exactly this overflow**: the comment above `skyPortBeginFan` (sky.c ~1738) records that the IsWater quad is excluded from D227's tile-shift safety valve because both texunits read the same vertex tc, so a tc rescale would need matched shifts on BOTH tiles and "shifting both makes them sample identically, which flattens the cross-fade"; the 2026-09 decision was that "the water quad keeps the plain 1:1 tc and simply tolerates the overflow on its horizon vertex, exactly as it did before D227." The mechanism is real: `unk20/unk24` are S10.5 units reaching tens of thousands near the horizon; the fold rebases to a multiple of `SKY_TC_WRAP` (2048) but with k=0 an s16 tc holds only ±32767, so any wider span wraps. It was invisible before D229 because every water texel was green mottle garbage anyway; with correct blue texels the wrapped region now reads as a visibly different pattern + seam, and it tracks the view because the fan's S/T depend on camera orientation. (On N64 this draw is a verbatim RDP `G_TRI_SHADE_TXTR` coefficient block with no s16 tc — the overflow constraint is a port artifact of re-emitting as `gSPVertex` batches, same class as D227.) + +**Status (from §F table):** **OPEN — REOPENED (M-116 live playtest, same session): the `allowShift=TRUE` mechanistic fix below did NOT resolve the symptom.** User report on Frigate post-fix: water still "glitches, kinda goes back and forth between two graphics too quickly," and still "changes depending on your view unlike the sky" (i.e. the sky, using the identical `skyPortBeginFan`/`skyPortEmitTileShift` mechanism post-D227, no longer has this problem, but water still does after getting the same treatment). This means the `allowShift=FALSE→TRUE` change either isn't the actual fix, or there's a second mechanism specific to water's two-texunit cross-fade that the tc-shift alone doesn't address — most likely candidate: the shift only rescales the *shared* vertex tc uniformly, but the tile-0-vs-tile-1 sample-point difference is set by each tile's own `uls`/`ult` (RDP tile-space, not vertex-tc-space) — if per-frame `k` changes granularity of the *quantized* shared coordinate before each tile's independent `uls`/`ult` subtraction, the two tiles' effective sampled texel could drift relative to each other frame-to-frame in a way the static `GE_D227V` trace (single frame, single camera angle) never exercised. Needs a fresh live investigation, not a repeat of the same static-trace approach — a scripted or live multi-frame capture while rotating view, watching both tiles' *decoded* texel positions (not just vertex tc) frame over frame. Do not re-apply the same `allowShift=TRUE` reasoning without new evidence; the superseded mechanism write-up below is unconfirmed-by-playtest and may be wrong. The code change (`allowShift=TRUE` on the water quad) is left in place — it's not shown to be actively harmful, and reverting it isn't obviously better than leaving it, pending the fresh investigation. **Superseded analysis (unconfirmed by playtest, kept for reference):** ~~FIXED (port-layer, `src/game/sky.c`, `#ifdef PORT`) — confirmed the `allowShift=FALSE` tolerance was the cause, and the "flattens the cross-fade" objection was wrong.~~ Changed the water quad's call from `skyPortBeginFan(sp274, s1, FALSE)` to `..., TRUE)`, so it now gets D227's tc-shift safety valve like every other sky fan. Why the old objection doesn't hold: `skyPortEmitTileShift` replays **both** tiles' captured `SETTILE` commands with the identical `k`, so both texunits' decoded S/T are rescaled by the same `2^k` *before* each tile's own (unshifted, tile-native) `uls`/`ult` offset is applied by the RDP — the offset between tile 0 and tile 1's sample points (what drives the cross-fade) is preserved, not flattened, because the shift and the offset act at different stages. **Verified mechanistically:** `GE_D227V=1` on Frigate (`-level_26`) shows a water fan vertex spanning S=-166..299317, T=-6451..288410 in S10.5 units — tens of thousands of texels, the same order of magnitude as D227's pre-fix sky overflow — now getting `kS=4 kT=4` (previously forced to 0), decoding to small in-range tc values (100s, not wrapped). **Verified no regression:** `verify.sh frigate` and `verify.sh "surface 2"` (the two `IsWater` levels) both PASS crash-free post-fix; non-water sky levels (`statue`/`-level_22`) unaffected since only the water call site changed. Screenshot comparison at a fixed scripted-intro camera angle (frame 500, both builds) showed no regression, but that specific angle didn't happen to frame the overflowing part of the fan either before or after — the sinf()-driven cross-fade also makes frame-for-frame screenshot diffs across separate runs noisy (each run's shimmer phase differs), so a same-frame pixel diff wasn't a clean confirmation tool here; the `GE_D227V` trace is the real evidence — **but it turned out not to be evidence the fix actually worked in live play.** Cross-ref D227 (mechanism), D229 (made this visible). + +## D246 — Tiny pixel strips at the left and right edges of the screen, "like overscan" — look like raw pixels, not 3D graphics (M-116, user QA report). + +**Tiny pixel strips at the left and right edges of the screen, "like overscan" — look like raw pixels, not 3D graphics (M-116, user QA report).** Uninvestigated. The port renders at native 640×480 (`GE_NATIVE_W/H`; `gfx_current_native_aspect` set in `port/src/video.c:253,570`) and scales to the window on present, so the leading candidate is a scaling/blit rounding artifact: non-integer scale factors leaving 1–2 columns of uncleared backbuffer content at the edges (or an off-by-one in the blit rect). Secondary candidates: an RDP fill-rect/scissor off-by-one in a game DL or the F10 overlay hook (`gfx_run()` seam, D184), or GL edge filtering on the scaled texture. + +**Status (from §F table):** **OPEN — one candidate ruled out (M-116 follow-up), root cause not found.** Step (1) from the original plan is done: a `GE_PCDUMP` capture (Frigate, native 640×483 buffer, both against the existing save and a fresh EEPROM) shows clean, continuous scene content in the leftmost/rightmost columns — no dead/black/garbage strip at either edge. That means the defect is **not** baked into the native render itself (rules out an RDP fill-rect/scissor off-by-one in a game DL, and rules out D227/D245-style tc issues) — it must be introduced later, specifically in the SDL-window presentation path that `GE_PCDUMP` bypasses entirely (`gfx_run()` reads back the game's own render target directly, never the actual window backbuffer the user sees). Re-examined `gfx_adjust_viewport_or_scissor` (`gfx_pc.cpp:2174`): its floor/ceil rounding is already deliberately anti-gap (comment: "prevents sub-pixel gaps at viewport edges"), so a plain rounding bug there is a weaker lead than it looked; more likely candidates now are the `game_renders_to_framebuffer`-path MSAA resolve `glBlitFramebuffer` (`gfx_opengl.cpp:1252`, only exercised when `Video.MSAA>1` or the window size actually differs from the game's target size mid-frame — a path `GE_PCDUMP`'s headless capture doesn't exercise the same way a live resizable window does) or a genuine sub-pixel/DPI scaling remainder specific to the user's actual window dimensions. **Next, still needs the user (no live window access in this environment):** (1) confirm current `Video.MSAA` setting and window size/aspect at the time the strips were seen; (2) if `MSAA>1`, retest with `Video.MSAA=1` to see if the strips disappear (isolates the resolve-blit path); (3) report whether the strip width changes with window size (fixed 1px = blit-rect off-by-one; scales with window = scale-factor remainder). Cross-ref D247 (separate, now closed — don't conflate the two; D247's letterbox is confirmed-intended and top/bottom only, D246 is left/right and still unexplained). **M-141: Steam Deck playtest confirmation, new platform data point** — user reports "some artifacts left and right of screen, only a sliver... like the fullscreen isn't quite going to full screen" specifically in **Full Screen mode on Steam Deck**. Same symptom description as the original M-116 report (Windows). Checked: the Deck's own first-run preset (`videoApplySteamOSDefaults()`, `port/src/video.c:255`) sets `cfgMSAA = 4` by default — exactly the condition this row already flagged as the leading remaining suspect (the MSAA-resolve `glBlitFramebuffer` path, step 2 of the still-open bisection ask). Next: have the user set `Video.MSAA=1` via F10 and retest on the Deck specifically — if the strips vanish, this row's root cause is confirmed without needing any more code tracing. + +## D247 — Black bars top and bottom of screen — possible aspect-ratio defect (M-116, user QA report). + +**Black bars top and bottom of screen — possible aspect-ratio defect (M-116, user QA report).** Uninvestigated. Context: the port currently renders native 4:3 (640×480); widescreen is a *parked proposal* (`docs/dev/WIDESCREEN-FOV-PLAN.md` — PD-parity native 16:9 render, needs rule-#2 sign-off for its game-code HUD wave), so if the user's window/display is wider than 4:3 and the present path letterboxes to preserve aspect, the bars are current intended behaviour rather than a bug. If they appear in a 4:3 window too, it is a real defect (framebuffer sized wrong vs window, `videoCreateFramebuffer(w,h,upscale,autoresize)` → `gfx_create_framebuffer`). + +**Status (from §F table):** **NOT A BUG — confirmed faithful, unmodified N64 decomp behaviour, no code change made.** `GE_PCDUMP` captures (both against the pre-existing save and a fresh-EEPROM run, to rule out a stale `Screen` option from earlier test sessions) show the exact same inset on Frigate: real scene content occupies rows ~20–459 of a 640×483 capture (the 483 vs 480 is a separate, harmless 3-row capture-tool rounding quirk, not investigated further), i.e. roughly 220/240 of the vertical field — and `src/game/fr.h:34` defines `VIEWPORT_HEIGHT_DEFAULT_NTSC 220` (240 for the full field), consumed unmodified by `bondviewGetCurrentPlayerViewportHeight()` (`bondview2.c:7858`) as the **default in-game viewport height whenever `PLAYER_OPTION_SCREEN` is `SCREEN_SIZE_FULLSCREEN`** (the decomp's own default value, `options.c:128`) — `VIEWPORT_HEIGHT_FULLSCREEN` (304, no inset) is a red herring name; it's only reachable via the `cameraBufferToggle` branch, not normal solo play. This is GoldenEye 007's well-documented original TV-safe-area letterboxing, baked into ground-truth decomp constants with no `#ifdef PORT` anywhere near it — the N64 game genuinely doesn't fill the full field during normal gameplay. Ruled out a stale/leftover EEPROM `Screen=Wide/Cinema` setting from earlier QoL-testing sessions as an alternative explanation: a fresh EEPROM (default options) shows the identical inset. **No fix needed; this row closes.** If the user's window shows noticeably *thicker* bars than this ~8–9%-per-edge margin, or bars appear on the *sides* instead of top/bottom, that would be a genuinely different (and real) symptom worth reopening under a new label — but "thin bars top and bottom, present at any window size" is correct, original behaviour.

On the N64 (32-bit pointers) `sizeof(OSScClient)` is exactly 8 bytes, so offset 8 correctly lands on `client[1].next` — matching the write. On this 64-bit port `sizeof(OSScClient)` is 16 bytes, so the same hardcoded 8-byte offset instead reads the low 32 bits of `client->msgQ` itself (always a real, non-NULL pointer) — the gfx client's flag reads as permanently "nonzero" and silently falls onto the audio client's every-other-frame path, halving the game's real render/tick cadence to 30Hz although the retrace pacemaker itself was always ticking at the correct 60Hz. Same D122/D126/D132/D209 bug class (32→64-bit pointer-width struct-size growth desyncing a hand-rolled offset), just in the scheduler instead of a ROM-serialized struct. **Fix (`#ifdef PORT`, N64 line kept verbatim under `#else`):** read the real field by indexing the struct (`client[1].next == 0`) instead of hardcoding a byte offset — this naturally scales with pointer width on either platform and is the direct decompilation of what `osScAddClient`'s write side already does. **Verified:** `Video.DisplayFPS=1` overlay (`port/src/optionsoverlay.c`, D213) read a rock-stable "30 FPS" on `-level_09` (BUNKER1) pre-fix and "60 FPS" post-fix, same build/scene, screenshots captured via `GE_PCDUMP`. Rebuilt clean (`ninja -j1`, pre-existing unrelated warnings only); `-level_09` and `-level_20` both ran 12-30s post-fix with no crash (`ge007.crash.log` absent). No game-code files touched beyond this one mechanical read (`src/sched.c` is compiled for the PC target per `CMakeLists.txt`'s `SRC_ENGINE` list, not one of the excluded os/io files) and the audio client's own flag/path is completely untouched, so `#ifdef PORT`-gated audio pacing (D204 tempo work) is unaffected. **Note for `docs/dev/UNLOCKED-FPS-PLAN.md`:** this settles that plan's Phase 0 open question — the ~30fps default was a real port bug, not original N64 behavior or an artifact of retrace-rate tracking sim speed; the plan's default-preset baseline should be re-measured at the corrected 60fps before Phase 1 pacing work resumes. Not yet done: a full `verify.sh sweep` across all 21 levels (only `-level_09`/`-level_20` spot-checked this session) and a live human playtest for feel (input latency, animation smoothness, any level-specific perf regression now that render work happens twice as often per second). + +## D249 — LOD/culling breaks down on large open levels (Streets, Egyptian named specifically) at *default* FOV — far-away geometry has visible culling issues (M-119… + +**LOD/culling breaks down on large open levels (Streets, Egyptian named specifically) at *default* FOV — far-away geometry has visible culling issues (M-119, user QA report).** Distinct from **D222** (which is specifically high `Video.FovScale` breaking *near-screen-edge* culling on NPCs/objects — not implicated here, default FOV) and from **D218** (the fog/far-clip *tint* boundary at wide FOV — also not the same symptom). This report is at the stock FOV, on the game's two biggest/most-open outdoor-scale levels, affecting *far* geometry specifically — points at either (a) a portal/room-visibility BFS cutting off too aggressively at range on large multi-room layouts (same neighbourhood as D233/D234's near-camera portal-cull bugs — worth checking whether D233's `gfx_sp_tri1` w<0 trivial-reject fix, which only guarded *behind-camera* vertices, has a sibling far-plane/depth-range case), or (b) GE's own N64 LOD/detail-swap system (mip-tile / simple-model substitution at distance — see D218's still-open question of "does GE have a separate geometry/object LOD-swap distinct from `Visibility.FarFog`") not being ported faithfully, popping or dropping geometry instead of swapping detail level. **Second, separate ask bundled in the same report:** the user would like LOD **improved** in general (presumably distance-based detail transitions look rougher/more abrupt on PC than remembered) but explicitly wants this **gated behind a toggle** so the original N64-accurate LOD behaviour stays selectable ("in case you want old school graphics") — i.e. this is a QoL feature request layered on top of a correctness bug, not one fix. + +**Status (from §F table):** OPEN — not investigated. Next: reproduce on Streets (`-level_20`) and Egyptian (`-level_08`, confirm level id) at default `Video.FovScale`; `GE_PCDUMP` a long sightline where geometry visibly drops/pops, cross-referencing whatever governs GE's LOD-tile selection (`gfx_lod_tile_offset` family, already touched by D172/D219) and the portal/room-visibility walk (D233/D234 neighbourhood) to determine which of (a)/(b) is actually firing before designing a fix or the requested toggle. + +## D251 — **F10 options overlay QoL pass: + +**F10 options overlay QoL pass: (a) bottom rows drawn off-screen in the in-game 2D space — the layout assumed a ~320×240 field and hard-fit all rows, but `viSetXY` gives 440×330 on front-end screens (`src/game/front.c:8618`) vs 320×240 in-game (`front.c:8628`), so with 17 rows × 15u pitch + 2 header rows the last rows land at y≈282, off-screen whenever the panel is opened in-level; (b) MSAA row only cycled forward — `rowAdjust()`'s `ROW_MSAA` case clamped its index to [0,3] instead of wrapping, so left-click stuck it at 8x with no way down via clicks; (c) manual % rows (`Video.DrawDistance`/`Video.LodDistance`) showed unconditionally even while their `*AutoFov` toggles were on, where the percent is inert/misleading. + +**Status (from §F table):** **FIXED (port-only, `port/src/optionsoverlay.c`).** (a) The panel now computes how many rows fit the *actual* current 2D height (`maxVisibleRows()` from `viGetY()`) and scrolls: a visible-row window (`s_scroll`) follows the selection, driven by wheel (`optionsOverlayScroll`) and arrow/D-pad at the list edges; layout, mouse hit-testing (`overlayRowAtY` now returns a visible position) and keyboard nav all index the visible list (`s_visIdx`/`s_visN`, `s_sel` is now a visible-list index), so it fits both 240- and 330-tall spaces with no per-space tuning. (b) `ROW_MSAA` wraps `(idx + dir + 4) % 4` — OFF→2x→4x→8x→OFF in both directions, matching the already-wrapping `ROW_ENUM`/`ROW_RES`; sliders keep clamping (standard for drag-able values). (c) New `Row.hiddenIfOn`/`hidePtr` fields: a row is hidden while the named option is nonzero — `Draw distance %` hides under `Video.DrawDistanceAutoFov`, `LOD distance %` under `Video.LodDistanceAutoFov`; rebuilt every frame in `overlayUpdateVisible()` (selection clamped into range when its row vanishes). Hint line updated to "click / drag / arrows / wheel". **Verified:** compiles clean in the full 241-target build; final link of this session was blocked only by a running game instance holding the exe (re-link pending). Not yet eyeballed live: scroll feel at 320×240, hover/scroll interaction, and the auto/% row appear-vanish transitions. Cross-ref D213 (FPS readout in the same file), D218/D249 (the auto-coupling these rows expose). **Follow-up after live test:** (d) list navigation (wheel + arrows) wrapped at both ends, so scrolling past the bottom made the highlight "repeat" from the top — now clamped at both edges like a normal PC settings list; (e) new `Input.SensLink` toggle (default ON, registered in `port/src/input.c`) links the aim/turn sensitivity knobs: moving either rescales the other to hold the stock 38 (`Input.AimModeSens`) : 50 (`Input.MouseTurnSpeed`) ratio, via a re-entrancy-guarded pair-write in `rowSet()`; (f) the "Mouse aim speed" row now edits `Input.AimModeSens` (the knob the default GEPD aim path actually uses — it previously edited `Input.MouseAimSpeed`, which only feeds the legacy velocity-stick fallback and was inert under default settings). **Second follow-up:** hover-to-highlight removed entirely -- moving the mouse over the panel no longer moves the selection or scrolls; near a list edge the hover->select->scroll-shift->new-row-under-cursor feedback loop made the bottom of the list twitch/echo (the persistent "duplicate row" report). Selection now moves only by explicit click (which also selects the clicked row), wheel, or arrows. **Reassessment of the 4K-fullscreen ghost-row bug:** the presentation-UV-wrap theory is DEAD — `gfxFramebuffer` has zero readers (the textured-quad present never happens); presentation is a full-frame `glBlitFramebuffer` from the same-size MSAA FBO to the default framebuffer (fb index 0 is reserved for the window, `gfx_opengl_init`), which has no UVs and cannot wrap. The overlay DL draws each visible row exactly once, in-bounds, with its own scissor. Local repro (maximized 16:9 window + MSAA=4 + `GE_OPTIONSOVERLAY=1` + `GE_PCDUMP`) shows NO ghost — the FBO/MSAA path alone is not the trigger; the remaining variable is true fullscreen on the user's 3072×1728 display (driver/display-level suspect). Next: user bisection — Fullscreen ON + MSAA OFF (restart) → does the ghost persist? **User follow-up (logged, not fixed):** the 4K-fullscreen ghost is *intermittent* across launches, and the user suspects the `hiddenIfOn` appear/vanish transitions of the Draw/LOD distance % rows (visible-list resize while the panel is open) — unverified; note `overlayUpdateVisible()`+`overlayUpdateScroll()` are re-run together in both emit and input each frame, so a stale-state window would have to come from elsewhere (e.g. the one frame a row count changes). MSAA-off bisection still pending. User: in the sessions seen so far the ghost is present on *first open* of F10 (not only after an auto-toggle flip) — weakens but does not kill the appear/vanish theory (toggles had flipped in earlier sessions before a restart). **v0.2.0-pre playtest (user, latest build):** the symptom has changed — the panel's *bottom row now deterministically duplicates whatever item is currently selected* (e.g. MSAA appears both on its own row and again at the bottom), not just an intermittent 4K/MSAA ghost of the top row; suggests the visible-row window can contain the selected row twice (off-by-one in `overlayUpdateScroll`/`maxVisibleRows` bookkeeping) — investigate post-release. **QoL follow-up:** make the auto-linked % rows visually subordinate to their toggle (indent and/or dimmer value colour) so the pairing is obvious in the panel; hint line also reworded to "select: scroll/click, change: mouse/arrows". + +## D253 — Facility (and any level with a FORCECROUCH/LADDER linked special tile) SIGSEGV on Linux/Steam Deck — `stanCheckLinkedSpecialTile` stores to a garbage… + +**Facility (and any level with a FORCECROUCH/LADDER linked special tile) SIGSEGV on Linux/Steam Deck — `stanCheckLinkedSpecialTile` stores to a garbage `outFlags` pointer (D203 root cause).** The B-callback typedef `standTileLocusCallback_B_t` (`bondtypes.h:573`) declares the middle three params as `f32 f32 f32`, so on x86-64 SysV the caller (`sub_GAME_7F0B1DDC`, `stan.c:2228`) passes the 6th arg (`record`) in **`%rdx`** (3rd integer slot; the floats take xmm0–2). But the actual implementation `stanCheckLinkedSpecialTile` was decompiled with an all-`s32` prototype, so it reads `outFlags` from **`%r9`** (6th integer slot) — a stale scratch value left by earlier callees. On the N64 (MIPS o32) both prototypes agree: everything flows through GPRs a0–a5 in order, 6th arg = a5 either way, so the original is fine and the decompilation looked consistent. The mismatch stays dormant until a tile actually hits the FORCECROUCH or LADDER branch and *stores* through `outFlags` → SEGV; that's why it was level-specific (Facility's opening crouch tile) and input-dependent, and why idle repros were negative. The sibling B-callback `stanLocusEdgeIsAboveY` already had the correct float prototype, which is why only this path was booby-trapped. **Fix (ABI-class, semantics-preserving):** declare the three middle params of `stanCheckLinkedSpecialTile` as `f32` in both the forward decl and definition (`stan.c:152`, `stan.c:2407`) to match the typedef; the body never uses them, and on N64 o32 f32 args occupy the same GPRs, so N64 codegen is unaffected. **Verified:** gdb run on WSL (gcc 15) — pre-fix, SIGSEGV at `stan.c:2441` with `r9=0x3` and valid `record=0x409fea00` in the caller frame; post-fix, the same walk route completes with no crash. Side benefit: the FORCECROUCH/LADDER branches were effectively dead-on-arrival on PC (any hit = crash); they now function. **Also observed post-fix (separate, WSLg-only):** a segfault *inside libgallium* during `gfx_opengl_upload_texture` (32×48 RGBA + mipmaps) while walking further — GL-driver-side under WSLg's Mesa; not reproducible on Windows; park as a new finding if it recurs on real hardware. + +**Status (from §F table):** FIXED — Deck-verified: user got past the crouch tile with the re-cut bundle (a *new*, later crash is D255). + +## D254 — Linux crash handler destroyed its own logs: `ge007.crash.log` only ever contained the SIGABRT block, never the original SEGV. + +**Linux crash handler destroyed its own logs: `ge007.crash.log` only ever contained the SIGABRT block, never the original SEGV.** The POSIX `crashHandler` (`port/src/crash.c`) finished by calling `sysFatalError()` → `abort()` → SIGABRT, which re-entered the *same* handler (SIGABRT was one of the installed signals); the second pass reopened the log with `"wb"` and overwrote the first pass's SEGV block — faulting PC, signal, everything. The Deck firefight crash (D255) came back as a bare `SIGNAL: 6` abort record for exactly this reason, forcing offline disassembly of the CI binary to recover what the log should have said. **Fix (port-only):** re-entrancy guard (`inCrashHandler`, second pass `_exit(128+sig)` immediately) + terminate directly with `_exit()` instead of `sysFatalError()` (the Windows path already terminated directly for the same reason) + the Linux block now dumps the faulting context: `FAULT ADDR` (`si_addr`) and the full general register set (Rax/Rcx/Rdx/Rsi/Rdi/R8–R11, Rsp/Rbp) from the `ucontext`, so a field crash now names the bad pointer on its face. **Field-verified 2026-09-13:** the D255 Deck crash came back as `SIGNAL: 11` + `FAULT ADDR: 0x10` + full register set — exactly the format designed here; it directly identified the NULL-model case (see D255). + +**Status (from §F table):** FIXED — field-verified. + +## D256 — Saves (and config) silently failed to persist on Linux whenever the game was not launched from the directory containing `data/` — reported as "saves do not… + +**Saves (and config) silently failed to persist on Linux whenever the game was not launched from the directory containing `data/` — reported as "saves do not work at all" on Steam Deck.** `romdataInit` finds the ROM in `$S/` (CWD `data/`) *or* `$E/` (exe dir) *or* `./`, but `sysResolvePath`'s POSIX `$S` branch (used by `ge007.eep` and `ge007.ini`) only ever produced a CWD-relative path — its "fallback" was `./data/`, identical to the primary. Launch from any other CWD (Steam non-steam-game shortcut, terminal in `~`): ROM loads via the exe-dir candidate, game runs, but every EEPROM/config write hits `fopen(..., "wb")` on a nonexistent `./data/` and fails with a stderr-only "cannot write" — saves never persist, and **every launch also starts with default settings** (F10 changes don't stick), which presents as "draw distance/LOD is low" on levels like Dam where the user had raised `Video.DrawDistance` on another machine. The Windows branch already did CWD-else-exedir; the POSIX branch now mirrors it (`readlink("/proc/self/exe")`) and creates the directory best-effort so first-run writes don't fail. **Verified on WSL:** with exe+`data/` in `/tmp/fb2` and CWD=`/`, config/eeprom/ROM all resolve into `/tmp/fb2/data/` and a 25 s run completes clean; the pre-fix binary in the same layout fails to find the ROM at all. **Caveat:** if the user's Deck launch *was* from the bundle dir (CWD had `data/`), this fix does not explain their save failure — need the save-flow detail (does the memory-card screen appear? slot confirm? "saved" message?) before closing the report. Side note found while testing: a `data/` without the generated sidecars (`pccg-*/`, `pcmodels-*/` from `tools_pc/d69_emit.py`/`d43_emit.py`) starts fine but faults in `load_bg_file` (`bg.c:865`) on level load — the reserve functions warn "stage loads will fault" and return 0; expected degraded mode, not a new bug. + +**Status (from §F table):** FIXED (path half) — save-flow detail still owed from the user. + +## D257 — New `Game.AllUnlocked` option (F10; default flipped OFF for v0.2.0 — see D259): skip N64 progression entirely — all 21 solo levels selectable at every… + +**New `Game.AllUnlocked` option (F10; default flipped OFF for v0.2.0 — see D259): skip N64 progression entirely — all 21 solo levels selectable at every difficulty, 007 mode available, and the cheat menu fully populated. Port-layer only; no game-code edits.** Three mechanisms, all in `port/`: (1) `main.c` seeds the two live `LEFTOVERDEBUG` RAM flags after `configLoad()` — `debug_enable_all_levels_flag` (all levels) and `debug_007_unlock_flag` (007 mode; both in `src/game/debugmenu_handler.c`, same class as the existing `GE_UNLOCK_ALL` getenv hook in the getter); (2) the eep shim (`libultra.c geEepromPatchAllCheats`) patches the save block at read time — special-casing `fileValidateSaves`'s exact pattern (block 4, 5×96 bytes) — setting all 20 progression-gated cheat-unlock bits per slot (`unlocked_cheats_1/2/3`; the cheat menu row on mode-select only renders when ≥1 is set, `front.c interface_menu06_modesel`) **and** filling every *empty* stage/difficulty completion-time field with the max time 0x3FF (existing player times preserved); both are then CRC'd per slot with the game's own `fileGenerateCRC` or `fileValidateSaves` would wipe the slots. (3) `optionsoverlay.c` row so users can toggle OFF for faithful progression. **Why the completion-time half is required (found by user repro):** when ANY single-player cheat is active, `g_AppendCheatSinglePlayer` makes mission-select (`get_highest_unlocked_difficulty_for_level`, front.c) accept only levels with status `STAGESTATUS_COMPLETED (3)`, not merely `UNLOCKED (1)` — AllUnlocked's debug-flag path returns 1, so enabling a cheat locked every level ("could only do Silo"). Reading the save as a fully-completed campaign satisfies both branches. Time bit-math mirrors `fileGet/SetSaveStageDifficultyTime` verbatim (10-bit fields, difficulties 0–2; 007 times are virtual). **Pitfall hit during implementation:** the first mirror of `save_data` used `times[80]` instead of `(SP_LEVEL_MAX-1)*4 = 76`, making `sizeof` 100≠96 so the block-read size check silently never matched — now enforced by a compile-time `ge_save_slot_size_check`. **Semantics:** unlocked cheats/completions persist to `ge007.eep` on any subsequent save write (self-consistent; mirrors N64 where completing a level permanently unlocks its cheat). No *active* cheats are enabled (invincibility/all-guns stay OFF); weapons remain per-mission pickups. **Verified:** fresh eep — all 5 slots validate `stored==calc` under `GE_SAVELOG=1`; user playtest: all levels selectable at each difficulty, 007 mode present, cheat menu populated, cheats toggle and work (time-modifying cheats untested by user), mission select intact with all cheats ON. + +**Status (from §F table):** FIXED — verified by user playtest (PR #79 merged); default flipped OFF for v0.2.0 (D259). + +## D259 — `Game.AllUnlocked` (D257) breaks audio on a fresh save: with it ON, music and SFX load at volume 0 (silence). v0.2.0 ships with `AllUnlocked` default OFF. + +**`Game.AllUnlocked` (D257) breaks audio on a fresh save: with it ON, music and SFX load at volume 0 (silence). v0.2.0 ships with `AllUnlocked` default OFF.** User-observed during v0.2.0 artifact testing ("all unlocked seems to break sound"). **Mechanism:** a fresh `ge007.eep` is zero-filled, so every save slot is all-zero. On N64 such a slot fails `fileValidateSaves`' CRC check and is rewritten as `BLANKSAVEDATA` (`src/bondconstants.h:2148`), whose `music_vol`/`sfx_vol` are `0xFF` (max). With AllUnlocked ON, `geEepromPatchAllCheats` (`port/src/libultra.c`) patches the zeroed slots (cheat bits + completion times) and recomputes a **valid** per-slot CRC, so `fileValidateSaves` accepts them as-is and never calls `fileResetSave`. The volume bytes therefore stay 0, and `fileLoadSettingsForFolder` (`src/game/file2.c:1289-1290`) loads them verbatim: `set_mTrack2Vol((save->music_vol << 7) | (save->music_vol >> 1))` = 0 → silence. With AllUnlocked OFF the zeroed slots fail CRC and reset to `BLANKSAVEDATA`, which is why sound works in the default configuration. **Disposition for v0.2.0:** flip `portAllUnlocked` default to 0 (`port/src/video.c`; `SkipIntro` was already 0) — faithful N64 progression out of the box, F10 *All unlocked* still enables the goodie. The quirk then only affects users who deliberately toggle it ON with a fresh save (recoverable: raising the in-game volume writes a nonzero slot, after which the patch leaves volumes alone). **Deferred fix candidate (port-only, ~6 lines):** in `geEepromPatchAllCheats`, detect all-zero slots and seed `music_vol`/`sfx_vol = 0xFF` before the CRC recompute, emulating what `fileResetSave` would have done; real (nonzero) saves incl. a user-muted one stay untouched. + +**Status (from §F table):** **FIXED in v0.2.1** — the deferred fix was applied: `geEepromPatchAllCheats` now detects all-zero slots and seeds `music_vol`/`sfx_vol = 0xFF` before the CRC recompute, emulating `fileResetSave`; real saves (incl. a deliberately muted one) stay untouched. **By-ear confirmed by the user** (v0.2.1 test pass: fresh save, AllUnlocked ON — audio plays correctly). + +## D260 — v0.2.1 (user request): mouse-wheel weapon-select direction swapped. + +**v0.2.1 (user request): mouse-wheel weapon-select direction swapped.** Wheel-up now selects the *previous* weapon and wheel-down the *next*, matching the in-game wheel menu's on-screen layout (the port had them inverted vs the user's expectation).

On N64 the same stick level was the *fast-scroll* band (one step per frame), which D118d removed because digital sources peg there and it became runaway scroll. **Fix (port-only, `#ifdef PORT` in `src/game/options.c`):** a bounded auto-repeat helper `geWatchStickFastStep()` — while the stick is held past the smooth band (≥ 0x46 up / ≤ −0x45 down), step one extra item every `GE_WATCH_NAV_RATE` (6) frames after an initial `GE_WATCH_NAV_DELAY` (15)-frame hold; the first press still goes through the untouched latched path, so a tap behaves exactly as before, and the smooth band + D-pad/C-button edge-repeat are unchanged. Called from `game_options_inventory_navigation()` only. **Verified:** build green; headless smoke (`GE_INPUTSCRIPT` long-W-hold on the inventory page) runs clean.

Headless repro (`GE_INPUTSCRIPT` pulse train + `GE_PCDUMP`, Dam `-level_33`): watch can't open during the intro freeze (`bondviewFrozenMoveBond` zeroes input while `g_CameraMode == CAMERAMODE_INTRO`; freeze ends ~frame 1400–1500 on Dam, and controller reads run faster than sim ticks, so scripts are timed by trial); once open + paged to INVENTORY (R_JPAD), the watch UI renders but the centre of the face is empty for every item. **Root cause found and fixed as D264** (`renderdata.flags == 0` in the watch subdraw pass — the cross-global ModelRenderData template read zeroes on PC; `subdraw()` then gated *every* geometry node, emitting exactly 1 word instead of the model's commands).

The PC link places .bss and .data in separate sections, so the read is all zeros: **`flags==0`**, and every geometry emitter in the subdraw node dispatch gates on `renderdata->flags & 1/2` (e.g. `modelRenderNodeDl`) — so `subdraw()` emitted exactly one word (`gSPSegment`) per preview, no matter the item. Probes this session: entry gates all pass (hand has item, model header non-NULL), node tree present (~400 nodes, isLoaded=1), world-path geometry nodes carry valid built DLs — but in the watch pass `flags=0` on every node. **Fix (`#ifdef PORT`, values identical to the N64 ROM bytes):** explicit template — `ModelRenderData renderdata = {0}; renderdata.zbufferenabled = TRUE; renderdata.flags = 3;`.

Note for follow-up: the 71-word dump is a repeating {matrix/segment/light} unit with no `gSPDisplayList` in the first 24 words — if the user's re-check still shows no visible model, next suspects are LOD/distance gating of the local watch-space matrices (`modelUpdateDistanceRelations`, cf. 7c48f664) or fast3d handling of the preview sub-DLs (segment 3 / render modes). + +**Status (from §F table):** FIXED — build green, probes removed; visual confirmation pending. + +## D263 — v0.2.1 (user report): Facility — "Ourumov not shooting Trevelyan"; the scripted opening beat never triggers.

It is a multi-minute sequence that *starts* only when the player walks Bond west and down a floor into Trevelyan's room — Bond spawns 8900 units away on the upper floor with LOS blocked (probed directly: `stanTestLineUnobstructed` = obstructed, different stan tiles), identical geometry to N64. **Runtime verification** (`-level_34`, `#ifdef PORT` probes in the AI executor/vision path, all since removed): all 15 BG lists + guards start; Trevelyan alive on ai_18; every vision gate passes except the geometric ones at spawn distance; player movement confirmed working (note for future headless tests: under the port's default SOLITARE/natural-pitch scheme, walking is C-button/D-pad fed — W→C-up — and the analog stick carries pitch, so `GE_INPUTSCRIPT` SUP/SDOWN tokens do *not* walk Bond there; use UP/DOWN pulses). **Decisive test:** a temporary PORT-only teleport probe dropped Bond 65 units from Trevelyan at t≈12 s → seconds later: vision fires (chr 67 → ai_19), objective bit set, `SpawnChr body=7 pad=88` + squad, chrnum→78 on ai_23; ~2½ min later **`HitChrWithItem from_chr=78 target=67 part=8 item=6`** — Ourumov executes Trevelyan. Most likely explanation of the report: the tester never walked Bond into Trevelyan's sightline (or pre-D253 crash masked it). No game-code or port-code change required. **Kept from this session (test-harness only):** `port/src/input.c` — `GE_INPUTSCRIPT` analog-stick tokens were applied *after* the stick was already written out, so SUP/SDOWN/SLEFT/SRIGHT were silently discarded; the script override now runs before the clamp/write. + +**Status (from §F table):** RESOLVED (not a bug), but refined (v0.2.1 further user testing, 2026-09-15) — beat verified firing end-to-end on PC incl. execution shot; **user playtest confirmed the sequence plays normally.** **Refinement: the exact trigger behavior is significantly sensitive to Bond's precise location and does not fire 1:1 identically to the N64 original across different approach paths/positions** — consistent with the beat's own documented sensitivity (range/facing/LOS/same-stand-tile + a ≈1/49-per-tick random gate, see the mapped mechanism above), so this is likely the same finicky-trigger behavior rather than a new bug, but not confirmed byte-identical to N64 for every approach. **User confirms this does NOT block level progression** either way — logged for awareness, not tracked as an open defect. Probes removed; input-script stick fix kept. **M-141: re-confirmed by user, one more mechanism now documented — the standoff has a hard TIMEOUT fallback, not just the shot-miss/objective-bit gates.** User reported (misread at first as a new freeze) reaching the Ourumov/Trevelyan standoff, waiting without shooting or triggering anything else, and after a couple of minutes Ourumov delivered his lines and executed Trevelyan on his own — **this is by design**: `ai_22`'s label `0x05` OR-gate (four early-exit conditions: two objective bits, a "Bond's shot missed" check, and a third objective bit set by an unrelated guard's surrender elsewhere in the level) is not the only path forward — falling through the whole dialogue-timer cascade (`label 0x42`'s chain of `if_local_timer_greater_than` checks) reaches `label 0x13`, which unconditionally fires `chr_hit_body_part_with_item_damage(0x43, 0x08, 0x06)` (the execution) once enough real time has elapsed, no player action required.

Fixed; awaiting user visual re-test.** The earlier sessions misidentified the format: a live tri-time tile census (probe in `gfx_sp_tri1`, since removed) shows level_36's tree-card classes are (a) **IA8, line=64B → 64×16** (texdump r107), drawn OPA/bilerp/1-cycle/AC_NONE — *genuinely fully opaque* (A nibble F on 1023/1024 texels; opaque on N64 too) — and (b) **IA4, line=64B → 128×16** (texdump r117), drawn ZMODE_XLU/point/2-cycle with m2a=CLR_MEM/m2b=1MA, i.e. texel-alpha blended. There are no 32-wide IA tiles at tri time; the prior "32×32 tile" reading was wrong, and the whole earlier IA16 byte-pair/I11:A5 debate (r107) was analyzing an IA8 image as byte-pairs. **The wall's root cause:** r117 decoded as I2:A2 is a strip of ~13 discrete conifer silhouettes (trunk+canopy shapes visible in the ASCII render, `scratch/r117_ia4_alpha.png`) with a 3-level alpha ramp {0: 95% of texels, 85, 170} — faint dithered distant trees on N64. But `import_texture_ia4` read each nibble as intensity=`part>>1` (3-bit, SCALE_3_8) + alpha=`part&1`: A2=1 canopy pixels became **fully opaque**, A2=2 edge dithering became **invisible** → opaque repeating tree silhouettes = the "wall". The bug is inherited verbatim from the PD port (`pd_port/port/fast3d/gfx_pc.cpp` has the identical I3:A1 read — latent there, fatal for GE's tree strip). **Fix (applied):** `intensity = part>>2`, `alpha = part&3`, both via new `SCALE_2_8`; this is the hardware-correct RDP IA4 layout. Also cleaned up: the ia16 importer comment now states plain I8:A8 (the byte-pair read *is* correct IA16; the old "r107 proof" was misidentified data), and the earlier part-1 dimension fix stays (harmless/correct for real IA16 tiles). **Caveats/owed:** (1) user visual re-test of Surface 1 trees — headless A/B was in flight when work halted; a cross-run region diff was inconclusive (camera drift between captures); (2) the decode change affects *every* IA4 tile game-wide — regression-sweep other levels for dithered/alpha IA4 art that now renders with correct 3-level alpha; (3) if a hard repeating band remains after the fix, it is the opaque IA8 strip (a), which matches hardware and D236 needs re-scoping. **OUTCOME (user re-test): NEGATIVE — trees still render as the wall with the I2:A2 decode applied; the change was fully reverted (`git checkout` of `port/fast3d/gfx_pc.cpp`, back to the original PD-derived importers) and work is parked.** The census/RM/texture data above stands as evidence for the next attempt: the decode was *necessary* (I2:A2 is the hardware layout and r117 is unambiguously an authored tree strip under it) but *not sufficient* — remaining suspects, in order: (i) fast3d's blending of these XLU/2-cycle cards (texel alpha reaching the GL blend at all — the `texture_edge`/`SHADER_OPT_TEXTURE_EDGE` path forces `a>0.19 ? 1 : discard`, which for a 3-level ramp quantizes to opaque/discard, i.e. still hard-edged), (ii) per-card UV windowing/placement (all captured cards sampled the same u:0..64/v:0..16 window — confirm against N64), (iii) fog/distance. Note for the next session: verify what the N64 actually shows in that region before more port-side changes (the opaque IA8 strip is faithful to hardware either way). + +**Status (from §F table):** PARKED — reverted to baseline; evidence + suspect list above. + +## D258 — PAL/JP asset conversion is broken at the source-data level — `scripts/filelist.e.csv` and `filelist.j.csv` carry naming defects, so `gen_romassets.py e/j` (and… + +**PAL/JP asset conversion is broken at the source-data level — `scripts/filelist.e.csv` and `filelist.j.csv` carry naming defects, so `gen_romassets.py e/j` (and the d43/d69/d88 emitters' `find_row`) cannot resolve PAL/JP builds. v0.2.0's drop-in ROM feature therefore ships NTSC-U only.** Discovered while scoping issue #6 (drop-in ROM). **PAL:** 31 of the 512 model rows in `filelist.e.csv` have truncated/renamed basenames (an extraction artifact — e.g. `Pbridge_console` ×6 where the resource table says `Pbridge_console1aZ…3bZ`, `Pchrgrenadelauncher` for `PchrgrenadelaunchZ`). **JP:** one font row is mislabeled — `fontBankGothic_fontchartable.bin` @3044276 is named `fontZurichBold_fontchartable.bin` (a duplicate label). Both were proven without a PAL/JP ROM: (a) greedy two-pointer sequence alignment of the 512-row `file_resource_table.inc.c` model order against each CSV's model rows gives an exact 1:1 match (481 by-name + 31 positional for PAL), offsets strictly non-decreasing, and zero size anomalies vs US (all within [0.5×, 2×]); (b) JP font row proven by the contiguity invariant — Gothic kerning @3043600+676 = 3044276 exactly hits the mislabeled row, whose size (8716) equals the US Gothic chartable, while Zurich's own chain is contiguous one row later. **Consequence:** no PAL or JP PC exe has ever been buildable from this tree (latent — only NTSC was ever exercised); the CSV `file` column is a label only (emitters look up by basename, never read the path), so the repair is a pure data fix: rename the 31 PAL model rows + 1 JP font row to the exact table symbols. **Scope decision (v0.2.0):** ship drop-in ROM support for NTSC-U only — `prepare-assets.py`/the frozen `ge007-convert` gate non-US ROMs with a clear message after SHA-1 region detection; the CSV repair + multi-region matrix + per-region exes are deferred to the Part B follow-up. + +**Status (from §F table):** OPEN — repair path verified, not applied (out of v0.2.0 scope). + +## D279 — Backfilled — this label was consumed by an undocumented partial session (2026-09-14 ~23:00) that left artifacts in `scratch/` (`d279_run.log`… + +**Backfilled — this label was consumed by an undocumented partial session (2026-09-14 ~23:00) that left artifacts in `scratch/` (`d279_run.log`, `d279_imgmap_run.log`, `d279_g110.png`, `d279_g220*.png`, `d279_gray_1500.png`) but no written conclusion; the logs carry no D279-tagged lines, so its exact probe/finding cannot be reconstructed from the tree.** Next available label after it: D280. + +**Status (from §F table):** undocumented — artifacts only + +## D281 — `Game.AllUnlocked` (D257) still breaks audio, and can also break right-mouse aim, when enabled before any save has ever been written (v0.2.1 user testing… + +**`Game.AllUnlocked` (D257) still breaks audio, and can also break right-mouse aim, when enabled before any save has ever been written (v0.2.1 user testing, 2026-09-15) — a distinct regression from D259, which only fixed the all-zero-slot volume case.** User's empirical workaround: complete a level normally first (e.g. Dam on Agent, which writes a real save), THEN enable `All unlocked`; enabling it on a completely fresh install (no save yet) still reproduces both symptoms.

Scope: front-end menu input in `src/game/front.c` (or wherever N64 stick reads are gated by the active `controldef`) — likely wants a port-layer input remap for these menu contexts specifically, not a general control-scheme change. **M-141: root cause found + fixed, port-only.** `front.c`'s menu-nav code reads `joyGetStickX/Y` — the same emulated N64 "Control Stick" channel (`stick_x`/`stick_y`) that in-level gameplay uses. `port/src/input.c`'s gamepad poll routes that channel to the LEFT physical stick by default, but `naturalPitchMode` (D194/D238's SOLITARE-style scheme, **default-on**) reroutes it to the RIGHT stick for continuous look — and since menus share the channel, they silently inherited that reroute too. The poll already computed an unused `padMenuMode` flag (`current_menu != GE_MENU_RUN_STAGE/GE_MENU_INVALID`, previously only gating shoulder-button weapon-cycle edges); moved it earlier and added a `padMenuMode` branch that always sources `stick_x`/`stick_y` from the left stick outside a running stage, regardless of `naturalPitchMode` — matching the F10 overlay's existing left-stick convention (`optionsoverlay.c`). Zero effect on in-level control feel (the branch is inert whenever `current_menu == GE_MENU_RUN_STAGE`). Verified: build green; `-level_09`/`-level_20` unregressed (1100+ frames each, no crash) — bare `-level_XX` launches skip the front end entirely, so this only proves the gameplay path (unaffected) stays clean. **In-menu feel not interactively verified this session** (no physical gamepad available in this environment) — needs a human playtest with a controller to confirm the menu now navigates on the left stick as expected. + +**Status (from §F table):** FIXED (`port/src/input.c`, `#ifdef` not needed — port-layer-only file), feel unconfirmed. + +## D283 — Steam Deck first-run preset (D-unnumbered in `port/src/video.c`/`main.c`, `videoApplySteamOSDefaults()`) did not apply for a user who added the game via Steam… + +**Steam Deck first-run preset (D-unnumbered in `port/src/video.c`/`main.c`, `videoApplySteamOSDefaults()`) did not apply for a user who added the game via Steam in Desktop Mode and switched to Game Mode afterward — resolution stayed at some non-native value instead of the Deck's native 1280×800 (v0.2.1 user testing, 2026-09-15).** Root mechanism, confirmed by code inspection: the preset only applies when `getenv("STEAMOS")` is truthy AND no `ge007.ini` exists yet (`main.c:126-129`, before `configLoad()`); once any ini exists, it always wins over the preset on every future launch (by design, so user F10 changes persist). **Leading hypothesis (not verified on real hardware in this environment):** SteamOS's Desktop Mode (a normal Plasma/X11 session) likely does not export the same `STEAMOS` env var that the Game Mode/gamescope session does, so a Desktop Mode test-launch (a natural step when adding a non-Steam game via its file browser) creates `ge007.ini` with ordinary Linux defaults *before* the user ever reaches Game Mode — permanently skipping the preset for that install, since the ini already exists on the first real Game Mode launch. This exact caveat was already known internally (`docs/HANDOFF.md`: "a Deck that already has an ini needs `-fresh` or F10 to pick the preset up") but was never surfaced in user-facing docs (README/release notes) — same class of gap as the stale D230 release-notes reference. **Workaround (lighter than `-fresh`, which also wipes the save):** F10 → Resolution → 1280×800 manually; takes seconds, no data lost. + +**Status (from §F table):** OPEN — mechanism understood, root cause (Desktop-vs-Game-Mode `STEAMOS` env var difference) unverified on real hardware; user-facing workaround documented in README/release notes. + +## D287 — User-confirmed real, non-self-recovering freeze on Windows (M-141, 2026-09-15/16) after ~15-20 minutes with no input, triggered by clicking back into the… + +**User-confirmed real, non-self-recovering freeze on Windows (M-141, 2026-09-15/16) after ~15-20 minutes with no input, triggered by clicking back into the window.** Caught live under `tools_pc/debug.ps1` (gdb-attached), evidence preserved at `scratch/d287_freeze_gdb.txt`. Last real `frame N rendered` log line: frame 17616. The heartbeat (`portHeartbeatCheck`) then fired 3 times with a **growing** stall (8001ms → 13017ms → 18021ms, `frames=17616` unchanged all 3 times) and then stopped logging entirely, while the VI-retrace pacemaker (`D51 vi post #N`) kept incrementing at its normal ~60 Hz rate for well over 100 more real seconds until the user closed the window — i.e. the pacemaker/OS-timer side is alive, the sim/render side is genuinely wedged, not the D286 shape (which self-recovered after one dump). **Different from D286**: no explosion/level-streaming context (idle + refocus, not combat), and the growing-then-silent heartbeat pattern (vs. D286's single fire-then-recover) points at a different mechanism. **Leading lead, not yet confirmed:** at freeze time, `gfxFrameMsgQ` (`src/init.c`, the scheduler's 32-slot client completion queue, registered via `osScAddClient`) shows `valid=32/32` — completely full — while the VI-retrace queue (8-slot) is not (`valid=1/8`). A full *client* queue with the producer (scheduler) still ticking implies the **consumer** (the main thread's `osRecvMesg(&gfxFrameMsgQ, ...)` in the frame loop) stopped draining it — consistent with the main/render thread blocking on something else (a lock, a GL call, a Windows message-pump stall) during or after a long-idle refocus, not with the scheduler itself stalling. Not yet identified what that something is. A pre-existing, currently-unused diagnostic (`GE_D60`, `port/src/libultra.c:630+`) already watches `gfxFrameMsgQ` receives and looks like the right next probe to enable. **Next, concrete:** reproduce with `GE_D60=1` (and ideally `GE_INPUTLOG=1`) running under `debug.ps1`, leave the window idle+unfocused 15-20 min, refocus, and once frozen `bt full` the actual game/render thread (not just the auto-dump's generic `WaitForMultipleObjects` frames for `shedThread`/`audioThread`) to find what it's blocked on.

Visual sweep (contact-sheet montages, `docs/img/bugs/D288-silo-stray-triangle-sheet.png` covers frames 571-751; `-closeup.png` is a full-res crop of frame 691) shows: **clean at frames 481-561** (no triangle), **first appears between frame ~562-601**, grows continuously in screen size through frame ~711 (by which point it covers roughly a third of the frame), then **shrinks and is gone by ~731-741** as the scene cuts to the first-person shaft-corridor view. Sampled pixel color is **exactly uniform** across the whole triangle (`RGB(83,62,44)` / `#533E2C` at two different sample points) — no gradient, no texture detail — i.e. this is a flat-shaded (no per-vertex color variance, no texture bound) single triangle, not garbage/noisy vertex-color data. **Reading of the evidence:** the grow-then-shrink-then-vanish arc across ~15 real seconds of camera motion is the classic signature of a genuine 3D triangle in world space that the camera flies close to/through during the scripted pan — not a 2D HUD/UI element (which would stay roughly fixed in screen size) and not obviously a `D146`-class freed-memory read (which reads as noisy garbage bytes, not a clean uniform flat color). The flat uniform color argues this is a REAL, correctly-colored asset triangle whose position/transform is wrong, which points at the same neighborhood as D106/D233 (near-plane / w-clip mishandling in `port/fast3d/gfx_pc.cpp`) rather than a game-code or converter data bug — but this is a read of the visual evidence, not a code-level confirmation; no probe has been run yet. **Not yet identified:** which model/prop this triangle belongs to (nothing in `UsetupsiloZ.c` was grepped for a matching solid-brown material this session), and no `port/fast3d/` tracing was done to catch the actual triangle at draw time. **Environment note (new, useful beyond this bug):** launching `ge007.x86_64.exe` in the **foreground** under this session's Bash tool with `timeout N ...` produced **zero** `ppm/` output despite `GE_PCDUMP` being set and verified exported — the `ppm/` directory was never even created (`GE_MKDIR` never ran or `frames`-gated capture never fired). Backgrounding the same invocation (`... &`, `sleep N`, `kill`) worked immediately and reliably. Not root-caused (didn't block this investigation), but worth remembering for the next session that needs `GE_PCDUMP` from this same tool. **Next, concrete:** (1) grep `assets/obseg/setup/UsetupsiloZ.c` / the missile-shaft model's material table for a solid `RGB(83,62,44)`-ish prim/vertex color to identify the source asset; (2) add a temporary `#ifdef PORT` probe in `gfx_sp_tri1` logging any triangle whose post-transform screen-space bounding box exceeds some fraction of the viewport together with each vertex's `w`, gated to `-level_20` frames ~560-740, to catch the culprit triangle's `w` sign/magnitude at the moment it blows up — same style as the existing `GE_D271`/`GE_D104` probes; (3) cross-check against D233's `w<0` trivial-reject fix and D106/D271's near-plane portal-bound clamp to see if this is a third site with the same underlying class of bug, or a genuinely new mechanism. + +**Status (from §F table):** OPEN — visually confirmed and precisely bounded (frames ~562-741 of a bare `-level_20` boot), root cause not yet identified; promoted from the long-parked `GRAPHICS-BACKLOG.md` D171 entry with real evidence. + +## D289 — Dam: a crash in the computer room, not reproducible on a second attempt (M-141, Steam Deck user playtest). + +**Dam: a crash in the computer room, not reproducible on a second attempt (M-141, Steam Deck user playtest).** **User's own read, most likely: the same computer-terminal SIGSEGV as D255** (Facility door-opening terminals — root-caused and FIXED this session, M-141, `vtxstore_fix_refs` reading `Model*` through the wrong union field, a 32-bit pointer truncation).

Sunk-into-floor is a third concrete instance of the family (level-start floating, cutscene spin, now death-pose sinking) — worth keeping as one thread when it's next investigated live, since a single root cause (most likely the render-side puppet/joint transform, not collision) could explain all three. + +**Status (from §F table):** OPEN — same status as D173 (observed, not root-caused).

User's settings: max `Video.DrawDistance`/`Video.LodDistance`, high `Video.FovScale` (~130%). **Not an exact match for any existing tracked culling bug, but closely neighbors three:** D222 (high-FovScale culling breakage — but D222 is specifically *NPC/object* culling near screen edges, root-caused and FIXED, not ground/BG geometry); D249 (LOD/culling breakdown on large open levels — but D249 is at *default* FOV on Streets/Egyptian, and doesn't self-recover); D218 (wide-FOV fog/far-clip boundary artifacting — but D218 is a color/tint issue at the frustum edge, not geometry going missing). **Distinguishing features that don't match any of the three:** (a) the drop-out is transient and self-corrects without the player doing anything special, (b) it's ground/BG geometry specifically, not NPCs or props, (c) it happens *within* the draw-distance/FOV settings, not past a boundary. Leading unconfirmed guess, weakened by the correction above but not ruled out: a portal/room-visibility computation (the BFS the D106/D271/D233/D234 family already touches) temporarily excluding a room/cell that contains ground geometry until the walk recomputes on subsequent player movement — the widened-FOV-frustum framing no longer applies (the drop-out wasn't tied to an unusually wide sightline), but a room-transition/streaming-timing trigger at ground level is still plausible and fits the self-recovering, "normal progression" description just as well.

Hipfire and zoomed states scale by the same factor so the zoom magnification ratio is preserved exactly; no double-application; the smooth zoom interpolation is unaffected (scale is post-lerp). Residual human eyeball (low risk, cosmetic) at FovScale ~120–150 + full aim-zoom: the viewmodel (`c_perspfovy`, `bondview.c:644`) and frustum-cull (`currentPlayerSetCameraScale`) use the *unscaled* fovy, so a subtle viewmodel-scale or edge-cull-early mismatch is possible; the scope reticle is 2D screen-space, unaffected. Caveat (same root): edge geometry culls a hair early at large scale (cosmetic). **User-verified good at big FovScale.** New adjacent report → **D220**: 1P muzzle flash position shifts upward at higher FovScale (Jungle, M16) — likely the same unscaled-viewmodel-fovy root as the caveat above. Wide FOV also exposes the per-level draw-distance boundary → **D218** (logged, parked). **M-87: the frustum-cull residual is a real bug, not cosmetic** → split to **D222**. + +## D219 — PPK explosions render purple on Dam (M-87, user QA, "not 3D but noting"). + +**PPK explosions render purple on Dam (M-87, user QA, "not 3D but noting").** Effect-color defect, not a texture-decode one — likely the D172 particle-color family (`gfx_lod_tile_offset` / `G_CC_INTERFERENCE` channel-order class) recurring on a different particle type/weapon than the D172 fix covered, or a fresh instance of the same class. + +**Status (from §F table):** **RESOLVED (M-115, 2026-09-12)** — byte-order fix in `src/game/image.c` scoped by pixel format (16-bit family bswap16-at-store, 32-bit identity); user playtest-confirmed. Superseded history below, which began: **OPEN — observed, not investigated.** Next: `GE_PCDUMP`/`GE_TEXDUMP` a Dam PPK explosion; check whether it's the same `gfx_lod_tile_offset` tile-sampling defect D172 fixed for blood, on an explosion DL D172's fix didn't touch. **Status: re-checked at runtime M-90 — mechanism covered by the D172 fix on current `main`; close pending a human by-eye pass (folds into PR #47 playtest).** **M-89 triage (local-Qwen, static analysis only, not yet runtime-confirmed):** the explosion DLs (`assets/oddtextures.c` `globalDL_0x078/0x120/0x1c8/0x270…`) use the same `G_CYC_2CYCLE`+`G_CC_INTERFERENCE,G_CC_MODULATEIA2`+`G_TL_TILE`, tile0=IA smoke/tile1=RGBA fire mechanism as the already-fixed D172 blood/spark records — no separate/unfixed code path found in `explosion.c` or the asset DLs. If still purple after D172's fix (which the user's Dam report postdates — needs re-confirming on current `main`), the next suspect is the GLSL combiner implementation of `G_CC_INTERFERENCE`+`G_CC_MODULATEIA2` for cycle 2 specifically (`gfx_generate_cc`, `port/fast3d/gfx_pc.cpp:312-494`), not the tile-offset fix. **Next, concrete:** run Dam (`-level_33`) with `GE_D172=1` while triggering a PPK/grenade explosion and check for "BUG" lines in the log (silence = D172's fix already covers this DL and the row can likely close on a re-test; needs a scripted-fire repro, not yet built). **M-90 runtime re-check DONE (scripted-fire repro built with `GE_INPUTSCRIPT`): the D172 fix demonstrably covers Dam's particle DLs — row can close on a human by-eye pass.** Ran `-level_33` headless with `GE_D172=1`, 64 scripted Z-pulses (`GE_INPUTSCRIPT="200:Z;215:Z;..."`, ~15 controller-reads apart) and a `GE_PCDUMP` window over the same span. Result: **40/40 particle multitex tris log `SAMPLED1=tile1 (tmem=392)`** — the correct RGBA fire tile, i.e. exactly the post-D172-fix behaviour (pre-fix these read `SAMPLED1 = tile0 (tmem=0 fmt=IA)`, the smoke texture); **zero** "BUG"/unknown-GBI/D146-abort lines; **0** purple/magenta pixels (`r>120, b>120, g<90, r-g>50, b-g>50`) across all 28 captured frames. Caveat: the user's M-87 "purple" report may predate the D172 fix on their binary (playtests run on whatever build was current); this re-check proves the sampling path is correct on current `main`, which is as far as a headless pass can take it — a final by-eye look at a live Dam PPK firefight is the honest closer (cheap for the user, folds into the D217 PR #47 playtest). **M-108 — REOPENED, the by-eye closer FAILED.** User played a live Dam (`-level_33`) PPK firefight on the current `main` build (post-D233/D234 fixes, same session as D243) and confirmed explosions are **still blue/purple**, directly contradicting M-90's clean scripted-repro result (40/40 correct-tile samples, 0 purple pixels, 28 frames). This means the M-90 `GE_INPUTSCRIPT` scripted-fire repro was very likely **not exercising the same explosion instance/DL the live firefight hits** — plausible gaps: a different explosion variant (grenade vs. bullet-impact spark vs. enemy-death vs. PPK-specific muzzle/hit effect) using a DL the scripted test's Z-pulses didn't trigger, or a state/lighting/prim-color condition (M-89's alternate suspect: the `G_CC_INTERFERENCE`+`G_CC_MODULATEIA2` cycle-2 GLSL combiner implementation, `gfx_generate_cc`, `port/fast3d/gfx_pc.cpp:312-494`) that only manifests under conditions the synthetic repro didn't reproduce. **Do not trust the M-90 all-clear for this finding going forward** — it proved one particle path clean, not that Dam's live-fire purple is fixed. Next: a live `GE_PCDUMP`/`GE_D172=1` capture during an actual purple explosion in real play (not a scripted approximation) is now the only way forward — need to pin down exactly what triggers it (PPK gunshots hitting a surface/enemy? a thrown/tossed explosive? which). **User has now confirmed (2026-09-12) this is NOT Dam-exclusive — game-wide, not just suspected.** Treat as confirmed scope, not pending a second-level check. **User wants this actively fixed, not just triaged** — next session should prioritize a live `GE_PCDUMP`/`GE_D172=1` capture during a real explosion (any level) over further static analysis, since the M-89/M-90 static passes are exhausted on this finding without producing a fix. **New HIGH-interest lead (M-110): `explosion.c` never clears `G_LIGHTING` before drawing any of the 15 particle DLs** (`globalDL_0x078` through `0x9a8` in `assets/oddtextures.c`, all structurally identical, all `G_CC_INTERFERENCE`+`G_CC_MODULATEIA2`) — grepped every particle-draw call site in `explosion.c` (`gSPClearGeometryMode` calls at lines 883/1495/1718/2227 only ever clear `G_CULL_BOTH`/`G_FOG`/`G_CULL_FRONT`, never `G_LIGHTING`) and confirmed `G_CC_INTERFERENCE,G_CC_MODULATEIA2` is used nowhere else in the codebase, so it's safe to key a probe on it. The port's vertex path (`port/fast3d/gfx_pc.cpp:1301-1346`) branches hard on `rsp.geometry_mode & G_LIGHTING`: if lighting is on when these particles draw, the authored RGBA tint in `v->v.cn[]` gets reinterpreted as a normal vector, and the resulting SHADE color (fed into `G_CC_MODULATEIA2`'s `COMBINED*SHADE`) becomes a scene-light color instead of the DL's actual red/orange fire tint — a mechanism that would plausibly read as "wrong color, state-dependent, game-wide" exactly as reported, and would explain why a synthetic scripted-fire repro (M-90, no nearby lit models) came back clean while live firefights (guards/lit models on screen) don't. **Not yet confirmed** — this depends on whatever last touched `geometry_mode` before the particle draw in a given frame, which the game's own N64-accurate command order controls; it is not yet established whether this is a genuine port bug (fast3d misordering/dropping a `G_GEOMETRYMODE` command relative to real hardware) or something that would reproduce identically on N64 (in which case it isn't actually the D219 mechanism, since N64 doesn't show purple explosions). **Instrumented, not fixed:** added a `#ifdef PORT`/`GE_D172=1`-gated log line to the existing D172 multitex-tri probe (`port/fast3d/gfx_pc.cpp` ~line 1740, `gfx_sp_tri1`) that now also prints `geometry_mode` and flags `LIGHTING=ON <-- D219 SUSPECT` whenever one of these particle triangles draws with lighting on. Sanity-checked against the known-clean M-90 repro (headless `-level_33`, 40 scripted Z-pulses): probe fires exactly 40/40 as before, all show `LIGHTING=off` — consistent with the already-known-clean case, confirming the probe works and doesn't false-positive. **Next, concrete:** run `build-pc/d172_silo.bat` (or equivalent, `GE_D172=1`) and trigger a real explosion (any level, any explosive source) near visible character models; grep the log for `D219 SUSPECT`. A hit confirms the mechanism and turns this into a real fix (clear `G_LIGHTING` in the port's particle-draw path or in fast3d's geometry-mode tracking, whichever turns out to be the actual divergence from N64); a miss across a real purple-explosion capture rules this whole lead out. **M-112 (this session): decode-chain code review + two new inert diagnostic probes; runtime capture NOT obtained (environment limitation, see below). Confidence: LOW-MEDIUM on a narrowed next step, no fix applied.** Read the full N64 texture decompression ground truth for these assets end to end: `texLoadFromDisplayList`→`texLoad`→`texInflateNonZlib`/`texInflateZlib`→(`texReadUncompressed | texInflateHuffman/texInflateRle+texChannelsToPixels | texBuildLookup+texInflateLookup/texInflateLookupFromBuffer`) (`src/game/image.c`), plus `gimgFixupGlobalimagetable`/`gimgSyncCompiledGlobalDLs` (`port/src/gimgfixup.c`) and `import_texture_rgba16` (`port/fast3d/gfx_pc.cpp:653-681`). Findings: (1) `IMAGE_FIRE_0..14` are **not** `sImageTableEntry`-table images (unlike `IMAGE_IMPACTMULTI`/`IMAGE_IMPACTREDBRICK*`/flare/ammo images, which live in the 32 `sImageTableEntry` arrays at segment offset 0xAC8+ and get their `G_SETTIMG` marker synthesized at runtime by `texSelect`, `src/game/othermodemicrocode.c:318`) — FIRE_N's `gsDPSetTextureImage(...IMAGESEG(IMAGE_FIRE_N))` is baked directly into the compiled `globalDL_0x078..0x9a8` display lists (segment offset 0x000-0xA50) alongside the interleaved, correctly-rendering `IMAGE_SMOKE_0..14` (IA16). Both FIRE's and SMOKE's markers go through the *same* `gimgFixupGlobalimagetable` part-1 DL-bswap step and the *same* `texLoadFromDisplayList`→`texLoad` resolution — no separate/divergent table-offset math applies to FIRE_N specifically (this narrows away part of the open brief's option (a): there is no `sImageTableEntry`/`s_tbl_offs[]` bounds bug possible here, because FIRE_N never goes through that array class at all). (2) `texChannelsToPixels`'s `TEXFORMAT_RGBA16` case and `texReadUncompressed`'s `TEXFORMAT_RGBA16` case are decomp ground truth (byte-exact, `#ifdef PORT` free) and are format-generic, not texture-specific — a bug there would require a same-format sibling to also be wrong, and IMPACT/FLARE RGBA16 sprites (same `G_IM_FMT_RGBA,G_IM_SIZ_16b`, same underlying `texLoad`) are the only same-format comparison point on hand, **but this session did not runtime-confirm whether those actually render correct colors in game** — flagging as an unverified assumption inherited from earlier sessions' "shared decoder is proven correct" framing, not re-proven here. (3) `texSwapAltRowBytes` is already an unconditional no-op on `PORT` (D159, `src/game/image.c:2219`, `return;` before any format switch) so it cannot be format- or texture-selective on the port — ruled out as a contributor for FIRE specifically (it's equally a no-op for every other texture). **New, added, NOT yet exercised:** two matching `GE_D219RAW`-gated diagnostic probes (inert unless the env var is set, `#ifdef PORT`, no behavior change): (a) in `texInflateNonZlib` (`src/game/image.c`, right after the per-image header read, and again right after decode) — logs `texnum`, `format`, `width`, `height`, `compmethod` from the bitstream header, then the first row of decoded RGBA5551 pixel words, for every image shaped 16x14 (the FIRE tile shape); (b) in `import_texture_rgba16` (`port/fast3d/gfx_pc.cpp`) — logs the same pixel words as read back at upload time, so a session can diff "as decoded" vs "as consumed" to rule pool corruption/mis-addressing in or out. **Environment blocker hit this session:** could not get the built `ge007.x86_64.exe` to produce *any* stderr/log output when launched from this delegated agent's shell, across four different invocation strategies (direct foreground exec, backgrounded `&`/`nohup`, `cmd /c start foo.bat` detached, `cmd /c foo.bat` synchronous with a hard timeout) — the process either exits or is killed before a single `osSyncPrintf`/`sysLogPrintf` line reaches the redirected log file, even though every print call in this codebase does an explicit `fflush(stderr)`. A plain GUI sanity check (launching `notepad.exe` the same way) worked fine, ruling out a blanket "no GUI" sandbox restriction, so the failure is specific to this binary/environment combination and its cause was not identified. Per `env-no-runtime-verify` (session memory): runtime verification is session-dependent; treat this session's empty captures as inconclusive, not as evidence of anything. **Next, concrete (for a session that CAN capture runtime output, interactive or otherwise):** (i) run any level with `GE_D219RAW=1` during an explosion/PPK firefight (or simply on level load, since these are likely eagerly cached) and read the logged `compmethod` for `IMAGE_FIRE_N` — cross-reference against a `GE_D219RAW`-instrumented capture of a *confirmed-correct-on-screen* RGBA16 sprite from the sibling `sImageTableEntry` families (e.g. `IMAGE_IMPACTMULTI`) to see whether FIRE uses a different `TEXCOMPMETHOD_*` (the compressed-bitstream compression method, not the pixel format) than a texture confirmed to render correctly — `TEXCOMPMETHOD_LOOKUP`/`_HUFFMANLOOKUP`/`_RLELOOKUP` (`texBuildLookup`+`texInflateLookup*`) build/consume a packed-color lookup table with a completely different bit-layout code path than `_HUFFMAN`/`_HUFFMANPERHCHANNEL`/`_RLE` (`texChannelsToPixels`, per-plane R/G/B/A order); if FIRE's method differs from the working comparison texture's, that pinpoints exactly which decode function to scrutinize next, rather than continuing to treat "the RGBA16 decoder" as one monolithic suspect. (ii) if the compmethod matches, the bug is genuinely upstream of decode (ROM/asset-extraction data itself, not the decompression code) — at that point compare the decompressed byte stream against a reference N64 emulator's texture-dump of the same asset (this repo has no such reference on hand) to establish definitively whether the ROM bytes for FIRE really do decode to blue/purple on real hardware too (in which case the bug is actually downstream in the color-combiner path after all, reopening the D172/G_CC_INTERFERENCE lead this session did not have budget to re-examine) or whether the extraction into this repo's `assets/oddtextures.c`-adjacent ROM data diverges from the real cart image for just these 15 offsets. Probes left in tree, both inert by default: `GE_D219RAW` (`src/game/image.c` `texInflateNonZlib`, `port/fast3d/gfx_pc.cpp` `import_texture_rgba16`). **M-141: Steam Deck playtest confirmation, widened symptom scope** — user reports "blood is purple, shots on body are blue/green" (general, not tied to a specific level in the report). Blood/hit-decal color is a new specific instance beyond this row's tracked "PPK explosions"/"particle effects" framing — same RGBA16/particle-color neighborhood as D172/D252, worth keeping in mind together rather than as three unrelated color bugs; whichever gets a real runtime capture first (this row's own `GE_D219RAW` probe, or D252's `GE_D252`) should also check blood decals specifically. + + +## D250 — FPS is inconsistent/low on many levels after 60 Hz shipped (M-119, user QA; D248 follow-on). + +**FPS is inconsistent/low on many levels since the port started actually running at 60fps — drops to 20–40fps intermittently, described as worse than before (M-119, user QA report, follow-on from D248).** Very likely a direct consequence of **D248** shipping: the port's render+tick loop had been silently running at half rate (30Hz) for the entire life of the project (D248, M-118) — the *real* per-level CPU/GPU cost of rendering and simulating this port was always this high, it was simply invisible while D248 halved the work being asked of the hardware every second. D248's own write-up flagged this as an open risk ("any level-specific perf regression now that render work happens twice as often per second") and explicitly left a live playtest / perf pass as un-done. Not yet investigated which side (CPU sim, CPU fast3d command generation, or GPU draw) is the bottleneck, or whether it's uniform or level-specific (the user's report implies specific/intermittent, which fits a per-scene cost — draw-call count, overdraw, or a specific expensive subsystem — rather than a flat doubled baseline cost). **M-120: partial progress, real bottleneck not yet caught.** User report sharpened: ~45fps at 720p on a self-described high-end PC, present even outside of dedicated stress levels — worse than the coarse "many levels, intermittent" framing suggested. Two things ruled out this session: (1) **build flags are not the cause** — `build-pc/CMakeCache.txt` confirms `CMAKE_BUILD_TYPE=RelWithDebInfo` (`-O2 -DNDEBUG`) is the actual default (`CMakeLists.txt:75-76`, unconditional unless a cache already exists), matching what `./build-pc.sh` produces with no extra flags — a debug/`-O0` build is not the explanation. (2) **idle-load is not the bottleneck, at least not in this dev box:** `GE_D193=1` on `-level_09` (BUNKER1, small level) idles at a rock-steady `render=60 sim=60`, frame-render time ~2.5 µs·10^3 (2.5 ms); `-level_29` (STREETS, one of D249's flagged large/open levels) idles at `render=55-60 sim=60-62`, frame-render time 6-7 ms — both comfortably under the 16.7 ms/60fps budget with no catch-up clamp hits. **This does not reproduce the user's 45fps** — either the real cost only shows up under actual gameplay load (AI/combat/particles active, not an empty idle scene — matches D193's own "player fine, AI-driven cost is different" pattern) or it's resolution/GPU-fill-rate-bound in a way this box's small idle test window doesn't exercise (this session could not drive real keyboard/mouse input into the game to generate a loaded scene — no interactive input tooling available headlessly). Also spotted and ruled out in passing: the `D51 vi post` debug log firing every render frame in `port/src/libultra.c:781` is throttled to ~once/sec (`% 60 == 1`), not a per-frame cost — not the culprit, though it's a `TEMP D51` instrument that's been live since early porting and could be removed as cleanup. **M-120 continued, live session with the user driving the game directly — the sim/render split is now confirmed live, and several strong candidates are ruled out, but the actual cost is still unlocated.** Reproduced directly on Dam (`-level_33`): `sim` holds a healthy 59-67/s throughout, `render` sags to 45-50/s, and the CPU-side `frame rendered in Nus` cost (`gfx_run`'s software-RSP interpretation, `port/src/libultra.c:1252`) stays only 6-10ms the whole time — comfortably under the 16.7ms/60fps budget. That leaves a genuine, unexplained ~10-15ms/frame, and a live A/B pass ruled out every obvious GPU-side suspect one at a time, each via the F10 in-game overlay while watching `GE_D193`: **MSAA 2→1 and Anisotropy 16→1 — no change.** **FovScale 125→100 — no change.** **VSync 1→0 (true uncapped rendering) — render still pinned at ~60 max, never higher, and the bad-scene numbers were unchanged** (also tells us the ~60fps ceiling itself is not a vsync artifact — something else already caps the loop at 60, vsync or not). **Resolution 1280×960 fullscreen → 640×480 windowed — no change** (rules out GPU fill-rate/pixel-count entirely; the cost does not scale with pixels at all). **Found and fixed a real, separate bug in passing (did not turn out to be the active cause here):** `sync_framerate_with_timer()` (`port/fast3d/gfx_sdl2.cpp`) computes the remaining frame budget in 100ns units (`qpc_to_100ns`) and passes it straight to `sysSleep()`, which takes **microseconds** — a genuine 10x oversleep whenever that branch fires. Fixed (`left / 10`). But this path only runs when `target_fps` is nonzero (tied to `Video.FpsCap`), and the user's test config had `FpsCap=0`/`VSync=0` — confirmed live that the bug fix made no difference to the reported drops, because the buggy code path was never executing in that config. Still worth landing as a correctness fix for whenever `FpsCap`/`VSync` *is* active. **Added `GE_D250`** (`src/boss.c`, wraps `lvlRender()`, the DL-building/culling/scene-traversal step that runs *before* `gfx_run()` and is separate from it) to check whether DL-building was hiding the missing time — live-tested on Dam: **`lvlRender` averages only 0.5-1.5ms, also not the bottleneck.** So: known costs (`gfx_run` ~6-10ms + `lvlRender` ~1ms) sum to ~7-11ms, real frame period is ~20-22ms (45-50fps) — the remaining ~10-15ms/frame is resolution-independent, GPU-setting-independent, and not in either of the two obvious CPU call sites. Traced the dataflow one level further: the game's main loop (`src/boss.c` `bossMainloop`) blocks on `osRecvMesg(&gfxFrameMsgQ, ..., OS_MESG_BLOCK)` waiting for `OS_SC_RETRACE_MSG`, posted by a dedicated pacemaker thread (`portTickThread`, `port/src/libultra.c`) at a fixed cadence independent of how fast the consumer drains it — meaning the observed render rate is whatever the consumer (game+render loop, one OS thread hop away from the pacemaker) can actually sustain, not a directly-configured cap. **Leading remaining suspect: the emulated N64 inter-"thread" message-passing/scheduler round-trip itself** (`port/src/gesched.c`/`sched.c`, real OS threads + mutex/condvar standing in for the N64's cooperative SP/DP/main threads) — each hop (game thread → scheduler → SP "thread" → done-message back) is a real OS context-switch-and-wake, and Windows condvar/thread wake latency can easily run several ms per hop, unlike the free N64 hardware handoff this code was ported from. **Not yet confirmed** — this needs either a targeted timer bracketing the full scheduler round-trip (same technique as `GE_D250`, just at a different call site) or a real sampling profiler (Visual Studio's own, or Windows Performance Recorder/WPR) attached to `ge007.x86_64.exe` during a live bad-fps moment, which would show this directly without more printf-probe guessing. Ad-hoc per-call timers have now ruled out the two most obvious candidates without finding the cost; a real profiler is the better next tool. **M-120 — ROOT-CAUSED AND FIXED: `getenv()`.** Set up a real profiler as recommended (`tools_pc/perf.ps1`, new sister script to `debug.ps1`, wraps `xperf` CPU-sampling + context-switch tracing). A live WPR/xperf capture on Dam, with Microsoft's public symbols resolved (`-symbols`, downloads system-DLL PDBs), showed the dominant render thread spending only **5.2% of its CPU time in the game's own code** — **43% was in `msvcrt.dll`**, and within that, `getenv()`/`_getenv_helper_nolock` alone accounted for **~50% of the thread's entire CPU time**. Root cause: `port/fast3d/gfx_pc.cpp`'s `import_texture()` (runs on every texture bind) and several per-triangle/per-`G_SETCOMBINE` combine-mode probe checks (`GE_DTEX`, `GE_TEXDUMP`, `GE_TEXRAW`, `GE_D229` ×2, `GE_D172` ×2, plus `GE_TEXDUMP`/`GE_PCDUMP` in `gfx_opengl.cpp`) called `getenv()` **uncached, every single call** — unlike the safe `static int x = -1; if (x < 0) x = getenv(...) != NULL;` pattern already used everywhere else in this codebase (`ft_d193`, `ge_d116`, `dvm`, etc.). On a texture-heavy scene this is tens of thousands of Windows CRT environment-lookup calls per second (each a locked, locale-aware linear scan per Microsoft's msvcrt implementation), completely invisible to both of M-120's earlier timers (`gfx_run`'s "frame rendered in Nus" and the new `GE_D250` `lvlRender` probe) because neither one specifically isolated CRT/library time from the game's own code. **Fix:** cached every uncached `getenv()` site in `gfx_pc.cpp`/`gfx_opengl.cpp` with the established pattern — narrow, mechanical, zero logic change. **Verified:** the exact idle-Dam headless test that was pinned at 45-50fps before the fix now holds a rock-steady 60-61fps, zero dips, with no other change. This also retroactively explains why M-120's earlier resolution/MSAA/vsync A/B pass (all "no change") was so consistent — the `getenv()` cost was a large, *per-call* (not per-pixel) constant that swamped any smaller resolution-dependent GPU cost at every setting tried, so the A/B genuinely couldn't have detected a fill-rate difference underneath it. **User re-tested 1440p/4K after the fix and confirmed it's fine too** — the initial "still runs badly at 1440p+" report was from before this fix landed (a stale-build mixup, same class as the DLL-load-error false alarm earlier in this session); once actually re-tested on the fixed build, high resolutions hold up fine. **D250 fully resolved, all resolutions tested clean.** + +> The §F row had no status cell; the table row's status is derived from this entry's verdict text (ctx-opt Bucket B, 2026-09-15). + +## D252 — Particle effects cycle through a rainbow palette (M-124, user playtest of the v0.2.0-pre candidate). + +**Particle effects cycle through a rainbow palette (M-124, user playtest of the v0.2.0-pre candidate).** Shooting repeatedly makes the bullet-impact "sparks" slowly progress through the full hue wheel (~10 shots to sweep it); other lingering particle effects — smoke / explosion residue — show the same rainbow colouration instead of their intended grey/orange palette. **Mechanism context (verified this session):** particle tris carry no per-primitive material; their colour comes entirely from the ROM-resident state records `globalDL_0x078 … globalDL_0xa50` (`assets/oddtextures.c`, 15 of them) replayed per particle batch (`explosion.c:894`). Each record binds a **distinct** texture pair — `IMAGE_SMOKE_N` (IA, tile 0 @ TMEM 0) × `IMAGE_FIRE_N` (RGBA16, tile 1 @ TMEM 0x188) under `G_CC_INTERFERENCE` (TEXEL0·TEXEL1), and `explosionRenderPart` uses a fixed all-white default vertex (`explosion.c:215`) — so the intended per-stage colour is whatever those 15 fire/smoke pairs encode, and particles **age through the records** (`var_s2` 14→0 at `frame/flareanimspeed`), so a per-texture decode error surfaces exactly as a hue sweep over time / across shots. **Ruled out this session:** (a) the M-82/D172 tile-offset fix is correctly configured for this path — `gsDPSetTextureLOD(G_TL_TILE)` does NOT set the `G_TL_LOD` bit, so `rdp.tex_lod` stays false (`gfx_pc.cpp:2860`) and `gfx_lod_tile_offset` returns `i`, i.e. TEXEL1 genuinely samples tile 1; (b) the RGBA16/5551 texel decode in `import_texture_rgba16` is correct (big-endian, R=bits15-11 G=10-6 B=5-1 A=bit0). **Prime suspect: the width/height derivation in `import_texture_rgba16`** — `width = rdp.texture_tile[tile].line_size_bytes / 2`, `height = size_bytes / line_size_bytes`. The fire tiles are 16 px wide with a MASK_16 TMEM line (64 bytes), so `width` computes 32 (true: 16) and, with `size_bytes` = the LOADBLOCK's 16×14×2 = 448, `height` computes 7 (true: 14) — the GL texture would be built from the right pixels at the wrong dimensions, scrambling each of the 15 fire sprites into a different wrong-hued smear; that fits "slow rainbow progression" precisely (each aging stage = a different scrambled sprite). **Not yet confirmed** — needs one imported fire tile dumped and compared against the raw `IMAGE_FIRE_N` bytes (`GE_TEXDUMP`/`GE_PCDUMP`, or a targeted probe at the `upload_texture` call). **Per user instruction: documented only, NOT fixed for v0.2.0-pre** — ships as a known issue; pick up afterwards (cheap if the suspect holds: derive width/height from the LOADBLOCK's dtx/dlh rather than the tile line size, or special-case non-32-texel-wide RGBA16 tiles). D172/M-82 lineage. **M-141 update: the width/height suspect is REFUTED by the authored asset data, not just re-tested — the prior "prime suspect" reasoning assumed `line_size_bytes` derives from the tile's `MASK_16` wrap period (64 bytes ⇒ 32 texels), but `assets/oddtextures.c`'s actual `gsDPSetTile` for the RGBA16 **render** tile (tile 1, e.g. `globalDL_0x078:50`) sets `line=4` explicitly (independent of the mask), giving `line_size_bytes = 4*8 = 32` bytes ⇒ `width = 32/2 = 16` texels — and `size_bytes` from the paired `gsDPLoadBlock(...CALC_LRS(16,14,G_IM_SIZ_16b)...)` is 16×14×2 = 448 bytes ⇒ `height = 448/32 = 14`. `import_texture_rgba16`'s existing `width = line_size_bytes/2` / `height = size_bytes/line_size_bytes` formula therefore computes the CORRECT 16×14 for every fire tile, cross-confirmed by the pre-existing `is_fire_shape = (width==16 && height==14)` filter already hardcoded into `gfx_opengl.cpp`'s `GE_TEXDUMP` dumper (D219-era) — that filter only makes sense if 16×14 is what the importer actually produces at runtime. **Do not chase width/height again.** Also checked and rejected: the render tile's `gsDPSetTileSize(1,...,CALC_TILESIZE(56),CALC_TILESIZE(56))` sets a 56×56 texel-coordinate WINDOW for UV-wrapping the 16×14 content against the co-rendered 56×56 smoke texture (`G_CC_INTERFERENCE`, TEXEL0=smoke/TEXEL1=fire) — this is not a usable content-dimension source and switching to it (the naive "use SETTILESIZE instead of line_size_bytes" fix) would have made the bug worse, not better. **GEVR-TRIAGE item E (byte-group-order hypothesis) also does not apply new information** — the original session's decode-order check (still correct: `addr[2i]<<8|addr[2i+1]`, matches the already-fixed D228 IA16 sibling) stands; no runtime capture this session found a byte-order anomaly either (see below). **Root cause is now genuinely open, not "unconfirmed suspect"** — both named hypotheses are dead. Next investigator: the TMEM slot the fire render tile always loads into (`tmem=0x188`/392, `rdp.loaded_texture[]` indexed by tmem, hard-coded identically across all 15 `globalDL_0x078..0x9a8` records) is a plausible next avenue — 15 *different* ROM source images share one fixed TMEM address and one GL-cache key derived from `{texture_addr, fmt, siz, size_bytes, ...}` (`gfx_pc.cpp:~1962`); worth checking whether rapid record-to-record aging ever reuses a stale GL texture object keyed wrong, though this is an unverified new lead, not a confirmed mechanism. **Not runtime-confirmed this session** — added an env-gated diagnostic (`GE_D252=1` in `import_texture_rgba16`, `port/fast3d/gfx_pc.cpp`) that logs computed vs. SETTILESIZE dimensions and dumps raw texel bytes per distinct upload to `scratch/d252_raw_*.bin`, but two 35s/90s headless `-level_37` (Jungle) runs never triggered an explosion/fire draw (no player input available in this environment) — needs an interactive session or a longer/different-level run to actually fire the probe. **User-confirmed live, same session: still reproduces on plain bullet-impact sparks**, not just explosions — this is a much cheaper repro than an explosion (any gunshot against a wall/surface) and should be the target for the next `GE_D252=1` capture, not a scripted explosion. + +> The §F row had no status cell; the table row's status is derived from this entry's verdict text (ctx-opt Bucket B, 2026-09-15). + +## D255 — Facility firefight SIGSEGV on Steam Deck (v0.2.0-pre CI bundle; D253 fix confirmed working). + +**Facility firefight SIGSEGV on Steam Deck (v0.2.0-pre CI bundle, D253 fix confirmed working — user got past the opening crouch tile).** Crash during gunplay; abort-unwind backtrace points at `sub_GAME_7F09BAC4` (`vtxstore.c:158`) ← `sub_GAME_7F09BBBC` (`:220`) ← `lvlManageMpGame` (`lv.c:1302`) ← `bossMainloop` (`boss.c:567`). Disassembling the exact CI binary at the fault PC (`0x200db135`) gives `mov 0x14(%rax),%edi; mov 0x10(%rdi),%rax`: the function walks the active PropRecord list keeping `type == 1` — which is **PROP_TYPE_OBJ, not CHR** (the decompiler cast to the union's first member and misnamed the field `ChrRecord.chrflags`; it is actually `ObjectRecord.model` at `0x14`) — then dereferences `model->obj`. Two port-relevant wrinkles: (a) the load is **32-bit zero-extended** because the decomp types the field through the `CHRFLAG` enum, so a model pointer ≥ 4 GB would truncate to garbage; (b) the loop skips records whose `model->obj` is NULL but *dereferences* `model` unconditionally, so an active object with a NULL/freed `model` faults — plausible in a firefight where destructibles (crates etc.) die. Not reproduced on WSL after equivalent play. **Register capture (D254 format, 2026-09-13):** two more Deck crashes — Bunker mid-firefight, then Frigate with ~3 NPCs alive; log: `SIGNAL: 11 / FAULT ADDR: 0x10 / Rax=0x701e5f54 Rdi=(nil) / PC 0x200db135`. `Rdi` = the record's model value = **exactly NULL** → case (b) confirmed: an active PROP_TYPE_OBJ record with a NULL `model`, dereferenced by the unconditional `mov 0x10(%rdi),%rax`; truncation (a) and stale/garbage pointers are ruled out. Faulting PC matches the recorded disassembly (`sub_GAME_7F09BAC4` = `vtxstore_fix_refs`). Grep-verified: nothing in game code ever writes NULL into `ObjectRecord.model` — `clear_model_obj()` nulls `model->obj` only, and `objInit`/spawn paths only activate a record once model ≠ NULL — so the NULL comes from either a fresh/uninitialized record slot being activated or a destroy-path ordering race (model freed/nulled while the record is still active this tick). **Fix constraint:** any guard lands in game code (`vtxstore.c`) → needs rule-#2 sign-off; `port/` cannot intercept this dereference. Next: (1) decision on whether a NULL-model skip in `vtxstore_fix_refs` qualifies as an ABI-class exception (semantics-preserving defensive guard, PD analogue check); (2) if yes, add it plus a `#ifdef PORT` trace at the deactivation/model-free sites to name the path that leaves the record model-less. **Corrected, deterministic repro (v0.2.1 user testing, 2026-09-15, superseding the initial report): the trigger is Facility's computer terminals — the ones you ACTIVATE (interact with, not shoot/destroy) to open a door for level progression.** User confirms this is consistent/reliably reproducible on those specific terminals, on Steam Deck **and** Linux generally (not Deck-hardware-specific). This is a much stronger lead than the original "sometimes during firefights" — a terminal activation deactivating/freeing its associated object model while the record briefly stays active this tick is fully consistent with the destroy-path-ordering theory above, just via a scripted trigger instead of combat destruction, and gives a deterministic repro instead of a probabilistic one. **Next session should reproduce via terminal activation specifically**, not generic combat — much cheaper to instrument. **M-140: added a diagnostic probe (`GE_D255`, off by default, `#ifdef PORT`) — `vtxstore.c`'s `sub_GAME_7F09BAC4` now skips-and-logs instead of dereferencing when it finds a NULL model on an active OBJ record (identity + state fields), and `propobj.c`'s `objFree` logs every free call for correlation. Attempted a live Windows repro this session (5 terminal activations across 3 Facility launches, one direct `-level_34` boot each time): zero probe hits, zero crashes — Windows does not reproduce this, consistent with the existing WSL-negative result. Two negatives (WSL, native Windows) against one positive (Linux/Steam Deck) points at something genuinely platform-specific (allocator/timing), not a Windows-reachable path — don't spend further Windows session time chasing a live repro.** The probes are harmless (env-gated, zero behavior change when unset) and committed so a Linux/Deck session can set `GE_D255=1` and get the trace directly. **User report, 2026-09-15 (same day, later, real Steam Deck hardware on the published v0.2.1 release — unverified by this session, logging as reported, not re-asserting the activation theory as wrong):** Facility crashes **consistently on terminals being destroyed** (shot), not (only) on activation. Frigate crashed once during this same testing pass, specifics not recorded. Shooting terminals elsewhere/other attempts did not reliably reproduce. This is closer to the *original* pre-M-139 framing (combat/destructibles triggering the NULL-model race) than the M-139 "corrected, activation-only" theory — both are plausible triggers of the same underlying destroy-path-ordering race (any code path that frees/nulls an active OBJ record's model mid-tick), not necessarily contradictory. **Not yet reconciled or verified by a session with hands on the repo** — next Linux/Deck session should test both triggers (activation AND destruction-by-gunfire) with `GE_D255=1` set before revising the "reliable repro" framing again. **Reconciled, same day, further real-Deck testing (v0.2.1 published release): destruction is the trigger, not activation — confirmed across four levels.** Facility: **every** terminal crashes consistently when destroyed (not merely activated). Caverns: terminals near the radio objective crash when they explode — same mechanism, different level, rules out a Facility-specific asset/state bug. Archives: a **similar** crash when a guard's grenade detonates — same destroy-via-explosion mechanism, no terminal involved at all, which narrows the real trigger to "an object dying via explosion damage" in general, not anything terminal-specific. **Negative control:** shooting an entire room of terminals on Frigate did not reproduce it — so it isn't simply "any destructible OBJ record exploding" either; something about the specific object/scene state still gates it. Release notes updated to match (`.github/release-notes.md`, D255 bullet: "consistently crash the game when destroyed"). **Static lead for next session (untested, from this session's code read):** `objFree`'s destroy path (`propobj.c:1017-1039`, entered via `RUNTIMEBITFLAG_REMOVE` from explosion damage, `sub_GAME_7F04424C`/`sub_GAME_7F0442DC`) never explicitly nulls `ObjectRecord.model` — `clear_model_obj()` only nulls `model->obj`. The NULL therefore can't come from that assignment; it must come from either (a) `chrpropFree`'s freed slot being reused by `chrpropAllocate` for a *different*, not-yet-`objInit`'d record before `vtxstore_fix_refs`'s later same-frame pass reaches it (a stale-pointer/reuse race, not a field write), or (b) the active-list unlink (`chrpropDelist`) happening while some other code is mid-iteration over the same list (a modify-during-iterate bug) — explosion damage plausibly spawns new effect props (sparks/debris/smoke) in the same tick that immediately reuse the just-freed slot, which would explain why it's tied to *explosions specifically* and not simple destruction. **Next, concrete:** with `GE_D255=1` set (probes already in tree from this session, ship in any build off `release/v0.3.0` including the local Linux package built this session), reproduce on Facility from the Deck itself (Desktop Mode, launch from a terminal, redirect stdout to a file) and send the log back — the probe already logs the dying record's identity plus every `objFree` call, which should show whether the crashing record's `prop`/`obj` pointer address was recently freed-and-reused this same session. + +> The §F row had no status cell; the table row's status is derived from this entry's verdict text (ctx-opt Bucket B, 2026-09-15). + +## D152+ — D152 addendum — static audit + narrow fix (M-31). + +**D152 addendum — static audit + narrow fix (M-31).** Audited every `osSetIntMask(OS_IM_NONE)` in the *compiled* audio code (`event.c` `alEvtqNextEvent`/`alEvtqPostEvent`/`alEvtqFlush`/`alEvtqFlushType`, `csplayer.c` `__CSPRepostEvent`, `synaddplayer.c` `alSynAddPlayer`, `snd.c` `sndRemoveEvents`/`sndSetupSound`/`sndDeactivateAllSfxByFlag`): **all balanced on every path** — `alEvtqPostEvent`'s lone early `return` (`event.c:86`, freeList empty) restores the mask first. The §F D152 guess "libaudio has unbalanced early-return mask paths" is **not** borne out. Two real defects found + fixed `#ifdef PORT` (N64 verbatim `#else`): **(1)** `sndSetSfxSlotVolume` (`snd.c`) walks the live `ALSoundState` list and posts `AL_SNDP_RELEASE_EVT` to the shared `ALEventQueue` **without holding `OS_IM_NONE`** — unlike its structural twin `sndDeactivateAllSfxByFlag`, which wraps its identical walk. On PC that's an unguarded walk racing `amMain` *and* one lock acquire/release per matching sound; the mission-failed fade (`sndSetScalerApplyVolumeAllSfxSlot`→`sndApplyVolumeAllSfxSlot`→ this, every frame, every active sound) turns it into a per-frame lock-acquire storm on `mainThread` = exactly the §F dump's "hammers the event queue hard enough that the lock is left owned." Fix: hold `OS_IM_NONE` once across the whole walk (nested `alEvtqPostEvent` hits the recursive depth++ fast path, no new contention window); also wrap `sndApplyVolumeAllSfxSlot`'s slot loop so the whole volume update is one recursive hold (1 real acquire/frame instead of `SFX_SLOT_COUNT × active-sounds`). **(2)** The actual leak matches the §F dump's *other* hypothesis — "a transient thread acquired `OS_IM_NONE` and exited" (`gdb.txt` shows `New Thread`/`exited` churn). `port/src/libultra.c` `portThreadWrapper` now calls new `imThreadExitRelease()` after the thread entry returns: if that thread still owns `s_imHeld`, release the orphan immediately (+ `LOG_ERROR` naming it). This removes the wedge *and* the ~2 s steal hitch, and stops the **re-wedge** that occurs when a new host thread reuses the dead thread's pthread id and `imAcquire` mis-detects recursion (`s_imOwner == self`). The M-28 steal-lock stays as the last-resort backstop for a genuinely unbalanced *same-thread* path (none found, but cheap insurance). Build green (240/240); `-level_09` frame 300 renders 91.7% non-clear, crash-free; `-level_20` boots crash-free (frame-count flaky under load per D117/D134, no `D152:` log).

If that spurious bit happens to match the other two (genuinely correct) vertices' bits, `v1->clip_rej & v2->clip_rej & v3->clip_rej` fires and the whole triangle is dropped before it ever reaches OpenGL — even though GL's own homogeneous clipper (which *does* handle `w<0` correctly) would have rendered the visible part of it. Confirmed against the two screenshots: same room/camera/ammo-HUD, one frame is missing the room's ceiling trusses/walls (replaced by flat sky) while the console/terminal props in the same room still draw fully — exactly the "big background polys vanish, small prop models don't" split you'd expect, since large near-camera polygons are far more likely to have a vertex cross behind the eye than small self-contained prop meshes. The backface-cull code 6 lines below (`gfx_pc.cpp:1462-1495`) already special-cases this exact `w<0` hazard for its own cross-product sign (`(v1->w<0)^(v2->w<0)^(v3->w<0)`) — the trivial-reject block above it never got the same treatment. **Independent of D222** (D222 is a game-logic frustum-cull bug in `src/game/fr.c`/`bondview2.c` that only manifests at non-default `Video.FovScale`; this is a GPU-pipeline clip-rejection bug in `port/fast3d/` that fires at any FovScale, including the default 100, whenever the camera gets close to a large polygon — matching the report's "all levels, near doors" framing with no FovScale mentioned). Also independent of D106 (D106 fixed the *game-side* portal-visibility bbox computation for a different z==0 edge case in `bg.c`; this is the *renderer-side* per-triangle clip decision, a different stage of the pipeline entirely) — same neighbourhood/symptom vocabulary ("things vanish near a portal-adjacent boundary"), different bug. + +**Status (from §F table):** **FIXED (port/fast3d/gfx_pc.cpp, `gfx_sp_tri1`) — high confidence on mechanism, UNVERIFIED visually.** Fix: skip the trivial-reject AND-test entirely whenever any of the triangle's 3 vertices has `w<0`, deferring to GL's clipper instead (mirrors the cull code's existing w-sign handling one block below).

The actual bug: `palette_to_rgba32`'s `G_TT_IA16` branch read `intensity = palentry & 0xff` (low byte) and `alpha = palentry >> 8` (high byte) — backwards relative to the already-correct direct-IA16 decode two functions above it in the same file (`import_texture_ia16`: `intensity = addr[2*i]` (first/high byte after `gfx_dp_load_tlut`'s `PD_BE16` swap), `alpha = addr[2*i+1]`). A dim, fully-opaque palette entry (e.g. intensity=0x58, alpha=0xff) decoded backwards as bright and mostly-transparent (intensity=0xff, alpha=0x58) — exactly the white-patch symptom, on any CI-format material whose TLUT happens to be IA16 rather than RGBA16 (weapon metal/grip materials commonly are, since IA is a natural fit for grayscale metal with a separate opacity channel). Fix: swap the two lines to match the working convention. **User-verified live:** AK47 and other metallic guns render correctly (no more white patches). Verified crash-free with a `-level_34` headless run before the live check; a full 21-level sweep is still owed (not run this session — the user was using their own game instance concurrently, `verify.sh`/`taskkill` would have killed it). D217 · D161 lineage — same general "CI/LUT format-assumption" bug class, distinct specific bug.
