 | D159 | front-end wallet-Bond photo "interlaced"/combed (RC1 / D149) — `texSwapAltRowBytes` odd-row 8-byte pre-swap (N64 RDP odd-line TMEM XOR compensation) not reversed by fast3d | FIXED (`#ifdef PORT` no-op the swap in `image.c`) |
 | D161 | Depot (`-level_30`) ceiling = bright-blue speckle + radial rays (B2). A CI8 tile drawn with `gsDPSetTextureLUT(G_TT_NONE)` was decoded against the stale `rdp.palette` → garbage. Fix: `#ifdef`-free narrow route CI→I when `palette_fmt == G_TT_NONE` in `gfx_pc.cpp import_texture()`. | FIXED (`port/fast3d/gfx_pc.cpp`) |
 | D165 · D166 | input-layer polish (M-31, port-only, `port/src/input.c`): D165 front-end cursor is now a true ~1:1 pointer (P-controller estimating the game cursor via front.c's own integrator) instead of velocity²; D166 hipfire mouse pitch emits speed-proportional C-button pulses instead of a fixed digital threshold. | FIXED |
+| D180 · D181 | native-PC input pass (QoL run, `qol/native-pc-input-menu`): D180 = `Input.MouseCaptureMode` click-to-lock + absolute-cursor menu tracking + aim-speed default retune (`port/src/input.c`, `video.c`, port-only); D181 = `Game.ScreenShakeIntensity` route-(b) hook in `src/fr.c viShake` (`#ifdef PORT`, default 1.0 = no-op). | LANDED, config-gated, feel-checks owed |
 | D152+ | D152 addendum (M-31): static audit of every compiled-audio `osSetIntMask(OS_IM_NONE)` — **all balanced**, no unbalanced early-return. Real fixes: `sndSetSfxSlotVolume` now holds the mask across its list walk (matches its twin `sndDeactivateAllSfxByFlag`) + `sndApplyVolumeAllSfxSlot` batches the slot loop under one recursive hold (kills the fade-out lock-acquire storm); `portThreadWrapper` calls `imThreadExitRelease()` on thread exit (kills the "transient thread acquired `OS_IM_NONE` and died" leak + the pthread-id-reuse re-wedge). Steal-lock kept as backstop. | FIXED (`src/snd.c`, `port/src/libultra.c`, `#ifdef PORT`) — fade-out repro playtest-gated, not headless-verified |
 | RC3 · D167 | **Non-power-of-two texture wrap period (`docs/dev/TEXTURE-GLITCH-ANALYSIS.md` §6 RC3 — "textures repeat oddly", residual Depot-ceiling noise after D161).** The N64 RDP masks the texel coordinate of a wrapping render tile at `1<<mask`, and GE sets `mask = texDimensionToMask(dim) = ceil(log2(dim))` (`src/game/tex.c:361`), so a non-PoT tile (Depot's 65×65 / 96×48 / 56×56 room surfaces) repeats at the **next power of two**, not at its image size the way GL `GL_REPEAT` does → the pattern is squashed/stretched and the seam lands in the wrong place. fast3d never stored `masks`/`maskt` at all (`gfx_dp_set_tile` dropped them) and wrapped purely at the uploaded image dimension. **Fix (`port/fast3d/gfx_pc.cpp`, behind the existing `Video.WrapFix` knob, default OFF):** store `masks`/`maskt` on the tile; in the hoisted per-texunit pre-wrap block in `gfx_sp_tri1` (D74 block — already lifted out of the vertex loop, indexed by texunit `t` not vertex `i`), when the tile is WRAP (no CLAMP/MIRROR bit) and `1<<mask != tex_width`, fold the UV at the N64 period `1<<mask` and clamp the `[dim, 1<<mask)` overflow band (which is a TMEM smear on console, no real texels) to the last texel so it reads as an edge streak instead of a bogus early image restart. `GE_WRAPFIX=0/1` env override added (env wins over the ini, matching `Debug.FrameDump`). **Per-level captures (`-level_09`/`-30`/`-34`/`-20`, WrapFix OFF vs ON, `GE_PCDUMP` 6-frame windows):** no crashes, 6/6 frames each; on settled/comparable frames Silo is ~pixel-identical (phash 0–11), Facility 180–260 pixel-identical, Depot shows small localized texel changes on ceiling/wall cells (dmean 5–9, no structural break); the large per-run deltas are all the D117 intro-camera-pan nondeterminism, not the fix. Default kept **OFF** — no regression, but a headless structural diff can't confirm the Depot ceiling actually looks *better*; needs a human eyeball with `Video.WrapFix=1`. Default-off is byte-identical to golden (all new behaviour is inside `if (g_wrap_fix)`). D74's dead in-vertex-loop wrap block was already reworked/hoisted at M-30; this only adds the mask-period trigger. Confidence: **medium** (mechanism correct; overflow-band handling is an approximation, not exact TMEM-smear emulation; visual win unconfirmed). porting-notes.md §D. | KNOB ADDED, default OFF (`port/fast3d/gfx_pc.cpp`). Needs user visual check on Depot. |
 | D168 | **`GE_PCDUMP` / F12 PPM captures were vertically flipped — the entire source of the bogus D114/D116 "HUD/text X-mirror" (M-33, developer-confirmed).** `gfx_opengl_dump_bound_fbo` (`port/fast3d/gfx_opengl.cpp`) wrote `glReadPixels` output straight to a P6 PPM. GL framebuffer origin is bottom-left; PPM P6 is top-row-first — so every capture (and the `tools_pc/golden/` set, and every screenshot pasted into the finding log since M-6) was upside-down. On real hardware / an actual screen the game renders correctly (developer confirmed). The successive D114→D116 "shared fast3d mirror" investigations — each of which found *every probed stage clean yet the output "mirrored"* — were reading an inverted capture and pattern-matching upside-down asymmetric content (text, guards, the Nintendo logo) as "mirrored". Fix: emit PPM rows bottom-to-top. `tools_pc/golden/*.png` flipped in place to match (see `tools_pc/golden/README.md`); regenerate from a real run when convenient. **Not runtime-verified this session** (no ROM / toolchain in the migrated tree — see the migration note) — needs a fresh capture to confirm text reads normally. Confidence: **high** (mechanism is unambiguous; developer has hardware confirmation the screen is correct). porting-notes.md §D2. | FIXED (`port/fast3d/gfx_opengl.cpp`); D114 / D116 reclassified as capture-orientation artifacts (below). |

 | D177 | **Ladders don't work** (user QA report): climbing is non-functional and **blocks progression on some levels**. FUNCTIONAL bug, not cosmetic — ranks above the graphics backlog. Untested by every harness so far (level sweep is boot-only; no scripted ladder input). Suspects: player ladder state machine in `bondview2.c`/chr physics (struct-offset family D100/D140), or the climb input mapping (A-button hold?) not reaching the game on the PC input path. **Next:** repro on a level with a mandatory ladder, check whether the player's ladder state ever changes (probe) vs the input never registering (`GE_INPUTLOG`). | Observed, NOT investigated — high priority (progression blocker) |
 | D174 | **"No blood effect" (user QA report).** Likely the unverified D120 decal fix: `d43_emit.py` now emits the opcode-0x18 `PointUsage[]` chain, but it was never interactively verified and requires a full sidecar regen to take effect (`debug.ps1` does not regen). Spray path is D172 (draws, wrong colour) — total absence would be new. See `GRAPHICS-BACKLOG.md` D174. | Observed; first step = BUNKER1 firefight with regenerated sidecars |
 | D173 | **Third-person Bond model spawns too high** (user QA report): the player-representing figure at level start floats well above the ground "a lot of the time" while the actual player spawn is correct; same on the Cuba end credits — JB ~6 ft in the air above Natalya. D75 animated-model family but a *position* defect, not absence (M-33: gun-barrel Bond renders fine). Suspects: intro/credits puppet chr spawn position vs model base transform; anim root-motion accumulation (`modelSetAnimFrame2WithChrStuff`, cf. D156); packed-float `coord3d` decode in intro setup. "Player spawning OK" localises it to the render-side model, not `g_CurrentPlayer`. See `GRAPHICS-BACKLOG.md` D173. | 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).** 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-<region>/{pcmodels.bin,manifest.csv}` and stage bg/stan from `data/pccg-<region>/{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. Relative path unchanged for legacy/grabbed. **(B3) `Input.MouseAimSpeed` default 25 → 16** (aim mode still overshot at 25 per the backlog). | LANDED, port-only, no `#ifdef PORT`. Build 241/241, `-level_09` framediff 3/3 within threshold (unregressed), `GE_STARTMENU` menu boot crash-free. **Feel-checks owed** (headless can't drive the mouse): click-to-lock ergonomics, absolute menu tracking, the new aim-speed default. |
+| D181 | **`Game.ScreenShakeIntensity` — first route-(b) `src/` gameplay-cosmetic hook (M-XX QoL run).** `src/fr.c viShake()` gains a single `#ifdef PORT` line — `intensity *= portScreenShakeScale;` (extern `f32`, defined + `configRegisterFloat`'d 0.0–10.0 in `port/src/video.c`) — before the existing clamp. 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. N64 build (no `-DPORT`) keeps the original line verbatim. Precedent per `docs/BACKLOG.md` "Fun features → screen-shake intensity slider" and AGENTS.md #2's documented-exception path. Same policy class as a future FOV hook. | LANDED behind config, default = original. Build green. |
 | 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 |
 | D88.1–D88.3 · D88.5–D88.6 | `Usetup*Z` header + sub-table width/endian conversion (`d88_emit.py`) | resolved |
