docs(findings): migrate fat §F rows D123-D151 to tail sections (ctx-opt P1, batch 1/8)
16 rows: topic/status cells moved verbatim to new '## Dxx' sections under a provenance divider at file tail; table rows now carry a one-line summary + pointer. CSV regenerated, label set unchanged (171). Nothing deleted.

| D274 | **D236 wall, seventh pass — probe identity (`seq`) proven unreliable both mid-run (cache-hit staleness) and cross-run (shared runtime-arena address reuse); fixed with an unconditional per-slot address stamp.** Resolved the prior pass's open "content vs. decode" question as a bug in this session's own offline analysis (wrong palette byte order — native/little-endian, not big-endian), not a port bug: the port's existing CI palette decode, applied correctly, reproduces a plausible soft gradient on the real, address-confirmed wall-card texture. 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. Attempted class-isolation A/B was inconclusive (black frame). | `d267_slot_addr` fix live (always-on); content/decode question CLOSED; mip-presence CLOSED; wall still open, see D236/D276 |
|
||||
| D273 | **D236 wall, fifth pass — user-supplied N64 reference screenshot obtained (discrete tree silhouettes, not a sheet); a pre-existing, undocumented `GE_D273` palette-decode A/B probe found in the uncommitted tree was tested against it and RULED OUT.** Standard-ARGB1555 vs. inherited-shifted CI palette decode: wall pattern visually unchanged either way; unrelated CI8 textures (snow path, viewmodel skin) corrupted by the swap. Not the wall's cause; `GE_D273` stays default-off. Flags a process gap: a live investigative lead sat in the working tree undocumented across a handoff boundary. | RULED OUT (`port/fast3d/gfx_pc.cpp` `palette_to_rgba32`, pre-existing/uncommitted `GE_D273`) — wall still open, see D236/D272 |
|
||||
| D272 | **D236 wall, fourth pass — per-card S/T audit (HANDOFF next-step #1) RULES OUT "identical UV window" and "converter bug"; the wall cards genuinely sample a wide, per-instance-varying UV range, verified authored in ROM, not injected by `d43_emit.py`.** New `GE_D272` raw per-vertex UV+tile probe (`gfx_sp_tri1`), filtered to D269's exact two oml classes. 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 |

As N64 `s32` it is 4 B, so `*(Gfx**)&sp54` reads 4 B of the adjacent stack float as the pointer high word → `_g = 0x03e4fca0_70081220` → wild DL write in `texSetRenderMode` (`othermodemicrocode.c:177`) the moment the crosshair raises. §A. | FIXED (`src/game/gunfire.c` `#ifdef PORT` — `sp54` is `Gfx *`) |

Fix: `op24_pointusage[puo] = nv` in layout + a byteswap loop (`put_s16(remap(puo)+2k, be16(src, puo+2k))` for `nv` = `numVertices` entries — a negative-terminated `s16` index chain, no remap) in the emit pass. Full regen chain re-run, round-trip validation passes. The `chr.c` guard stays as a safety net (SMALL-FIXES B3). | FIXED (`tools_pc/d43_emit.py`).

Same class as D94 (chraction 32-bit ptr truncation), but in a GBI DL word. The projection matrix in the same DL is fine (`get_BONDdata_field_10E0()` is a runtime `0x70xxxxxx` ptr, fits u32); the `gSPDisplayList(&globalDL_0xNNN)` refs are fine (port `Gwords.w1` is 64-bit `uintptr_t`, no macro truncation). ~30 `osVirtualToPhysical(<compiled matrix/vtx symbol>)` sites exist (`explosion.c`, `glass*.c`, `blood_animation.c`, `bondview2.c`) — all latent until that effect first draws. | resolved — `seg_addr()` restores the module high word for any fallthrough w1 in `[0x40000000, 0x70000000)` (module fixed-based at `0x140000000`, no ASLR; DRAM/KSEG0/segmented/phys all handled earlier). Jungle renders to frame 2400+ clean; `-level_20`/`-level_24` unregressed. **18→19/21.** (`-level_09` has a separate pre-existing boot crash, see below.) |

| D133 | intro render triage (M-20): the "intro renders mostly black" item in the M-18/M-19 handoff is **NOT a regression** — it is the D75/D76 parked-cosmetic steady state. M-17 (`9ec6121e`), whose handoff claimed "the entire intro renders — logos → gun barrel → cast", was built in a scratch worktree and captured with the same `GE_PCDUMP="20-900:20"` window: coverage is **pixel-identical** to HEAD `0b5f5d1a` (legal screen 6677 non-clear px / 2.17% on both; centred-logo frames ~7% on both; near-black between). 2D/text/texture layers draw; animated character-model layers (Nintendo-logo transform, gun-barrel Bond, cast models) never appear = D75 exactly. No cheap regression to fix; parked. Secondary: Facility `-level_34` + Jungle `-level_37` re-verify FAILED this pass (boot crash / frame-2 hang) — flagged in LEVEL-STATUS for a clean-machine re-check, not investigated (scope). | RESOLVED — not a regression, parked (D75/D76, `GRAPHICS-BACKLOG.md`) |
|
||||
| D134 | **Frame-2 boot hang / sweep "NO-FRAMES" flakiness — root-caused and fixed (M-22).** `osSpTaskStartGo` (port/src/libultra.c) posted the SP/DP task-done events with `OS_MESG_NOBLOCK` into the scheduler's 8-slot `interruptQ`, which the 60 Hz VI pacemaker thread also fills with `VIDEO_MSG`. A gfx task runs the whole frame synchronously on the sched thread (fast3d); the first two frames take 30-80 ms, so the pacemaker queues several retraces meanwhile. Once the queue is full the RSP-done post is **silently dropped** -> `__scMain` never clears `sc->curRSPTask` -> the client never gets `OS_SC_DONE_MSG` -> `bossMainloop`'s `pendingGfx` never clears -> permanent stall (log: `frame 2 rendered`, then `kernel heartbeat ... frames=2`, retrace queue pinned at `valid=8/8 ret=-1`). Reproduced 2 of 3 `-level_09` boots on an idle machine, i.e. most of what M-13..M-21 wrote off as D117 nondeterminism / machine load. `OS_MESG_BLOCK` is NOT the fix (the done event is posted from the sched thread, the queue's only consumer -> self-deadlock): `portPostEventForce()` drops the OLDEST message (always a stale retrace) and retries, and `portPostVIEvent` now reserves 2 slots. Verified: 6/6 `-level_09` boots reach frame 600 with 0 heartbeats (pre-fix 1/3). | FIXED (`port/src/libultra.c`) |
|
||||
| D135 | **Firefight crash — `bgTestHitOnObj` (`propobj.c:8446`) is an unported N64 GBI parser (M-22, WS6 playtest).** The object bullet-hit test walks a model's display list command stream with hardcoded 8-byte-N64-`Gfx` byte/word indices (`*(s8*)gdl`, `((u32*)gdl)[1]`, `((u8*)gdl)[5..7]`, the G_TRI4 nibble reads, the backward `G_SETTIMG` scan). On PC the model GDL is the 16-byte `Gfx` layout (`d43_emit.py`, `{u64 w0; u64 w1}`), so every access reads the wrong bytes → the walk desyncs on the first `G_VTX`/`G_TRI1` → `v->coord.x` deref off the end of the DL → AV (`0x709ae02a`, a near-miss past a live DRAM ptr = the §B signature). Triggered by `propobjFindHit` every time a shot ray resolves a hit on an object model (guards' dropped weapons, attached objects, shootable props) — invisible to `level_sweep.sh` (no weapon fire). Two sibling faults seen the same session (`texSelect`/`texSetRenderMode` wild `gdl`, `objFreeEmbedmentOrProjectile` `prop->obj`) are likely the same corrupted-object cascade. PD `bgTestHitOnObj` (`pd_port/src/game/bg.c:3635`) is the fully-ported ground truth. | FIXED (`src/game/propobj.c`, `#ifdef PORT` — reads `gdl->words.w0/.w1` shifts). **Second fault, same walker:** after the parser fix the Facility firefight then hit `0xc0000094` (int div-by-zero) at `objHit` `propobj.c:9717` `randomGetNext() % impact_sounds->thing2_len` — the ported texnum-recovery (`*(s16*)(phys(w1) − 8)`) returned a bogus positive `texturenum` (`(u32)` cast truncated a 64-bit `words.w1`; the N64 "texnum 8 bytes before the texture data" layout isn't guaranteed for the port's converted/replaced GDLs) → `g_HitTypeSounds[texnum & 0xf]` picked an entry with `thing2_len == 0`. Fixed: the PORT texnum branch now always returns `-1` (→ `g_HitTypeSounds[0]` = `isnd_default`, `thing2_len == 1`, safe). `texturenum` only flavours the bullet-impact sound/decal, so generic-hit is an acceptable degradation (park with D77). **Follow-up:** the BG room-geometry sibling `sub_GAME_…` (`bg.c:~3373-3646`, walks the D85-widened `ptr_expanded_mapping_info`) has the identical unported parser pattern — latent, fires on shooting walls/floor; not yet ported. |
|
||||
| D136 | **Stage-unload crash — `objFree` `obj->prop` reads float garbage (M-22, WS6 Facility playthrough).** After D135 cleared the firefight crashes the level is completable; then on teardown `lvlUnloadStageTextData` → `cleanupObjects` (`cleanup_objects.c:42`) → `objFreePermanently` → `objFree` (`propobj.c:994`) → `objFreeEmbedmentOrProjectile(obj->prop)` faults at `:888` (`prop->obj` deref). Real gdb `bt`: `obj` = `0x701bd730` (valid) but `obj->prop` = `0x3e567400405c30c0` — two packed `f32` (~0.21, ~3.44), i.e. a `coord3d` read as a pointer → `ObjectRecord.prop` (N64 `/*0x10*/`, after `inherits PropDefHeaderRecord` + `s16 obj; s16 pad; u32 flags; u32 flags2;`) lands at the wrong PC offset for this object's propDef type, OR the record is undersized and setup's `->prop` store never happened / was clobbered. Same family as D122/D132 (`tools_pc/d88_propdefs.py` per-type record sizing vs the compiled `ObjectRecord`/subtype layout). Type not yet identified — needs a gdb run with a breakpoint on `objFree` to read `obj->type` (`cleanupObjects` frees WEAPON/AMMO/MAGAZINE/COLLECTABLE/MONITOR/RACK/AUTOGUN/HAT/ARMOUR/GAS_RELEASING/VEHICHLE/AIRCRAFT/GLASS/SAFE/TANK/TINTED_GLASS via this path). Mission completes; crash is before the next briefing loads. | ROOT-CAUSED → **D139** (it was NOT a layout bug — `cleanupObjects` read the type from the wrong byte on LE and walked off the propDef blob). |
|
||||
| D139 | **Stage-unload crash root cause + fix (M-23).** `cleanupObjects` (`cleanup_objects.c`) walks `g_CurrentSetup.propDefs` with `(u8)obj[0]` as the record type — correct only because the header word `[u16 extrascale][u8 state][u8 type]` is **big-endian** on N64, so `type` is the low byte. 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. Not a `d88_propdefs.py` layout issue at all. | FIXED (`src/game/cleanup_objects.c`, `#ifdef PORT` — `CLEANUP_PDTYPE(o)` = `((PropDefHeaderRecord*)o)->type`). **UNVERIFIED** — the fast teardown test (pause→abort) hit D140 first; `-level_09` unregressed. porting-notes.md §C. |

Root cause (NOT "cache never allocated"): `something_with_watch_object_instance` (N64 player +0x230) is a **`struct Model` (0xBC) + its RW-data pool (0xC8) punned into a 0x184-byte hole** (`field_234..field_3B0`); three of those "fields" are Model members the game reads by name — `watch_scale_destination`==`.scale`, `pause_watch_related_adjust`==`.animframe1`, **`field_23C`==`.render_pos`**. `render_pos` IS populated (by `instcalcmatrices` via `subcalcmatrices` at `:8524`), but on x86-64 `sizeof(struct Model)` grows (4→8B ptrs) so `field_23C` no longer overlaps `.render_pos` → reads Model padding (~0) → NULL. Same class as D100 (gait Model) / D102 (weapon Model) / D56 (this very watch Model's pool). Fix: `#ifdef PORT` makes `something_with_watch_object_instance` a real inline `struct Model` + `u32 watchRwPool[192]` in `struct player` (`bondview.h`); `bondview2.c` redirects the 3 named reads to the member via `GE_WATCH_{ANIMFRAME,SCALE,RENDERPOS}` macros (N64 `#else` = the verbatim field). The D56 branch of `sub_GAME_7F07E7CC` drops its `static u8 watchRwPool[0xC8]` for the inline pool. | FIXED (`src/game/bondview.h`, `src/game/bondview2.c`; `#ifdef PORT`).

An N64 stick rarely sustains past ~0x46 on-axis so a human taps it; keyboard W/S (and SDL pads pegged at 0x80) sit there every frame → one keypress skips several items (breaks item selection needed to finish the game). Fix: `#ifdef PORT` macro `GE_WATCH_STICK_FAST{UP,DOWN}` → `0` for the port — stick list-nav then goes only through the latched single-step path (`watch_stick_y_pressed_*`, one step per press, existing game mechanism) and the -0x1e..-0x45 smooth-scroll band; D-pad/C-buttons keep edge-repeat.

The pages assemble their display text with `strcpy`/`strcat(buf, langGet(id))` (`options.c:3940-4068`, `front.c:3538-3562`, `propobj.c`). `langGet()` returns **NULL** on PC for a string bank the menu flow never loaded (D129/D143 guards — briefing/objective banks in the in-level watch flow), so `strcat(buf, NULL)` derefs NULL. 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.

| 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). Fade-out repro is **playtest-gated** — not reproducible headless, so not end-to-end verified; user should replay the mission-fail and confirm no black screen + no `D152:` steal/orphan log lines. | FIXED (`src/snd.c`, `port/src/libultra.c`, `#ifdef PORT`). porting-notes.md §D4. |

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). | **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. Confidence: HIGH on the mechanical correctness (bit-for-bit vs N64), MEDIUM that nothing else in the walk still bites. porting-notes.md §B (D135 corollary). |

| D156 | **Facility outro-cutscene "hang" — the actual fix (M-29, user bug report, 2nd occurrence after D155).** After D155 shipped the user re-ran the playthrough and it hung again at the end of Facility — same stack (`modelSetAnimFrame2WithChrStuff` ← `modelTickAnim` ← `chrUpdateAnim` ← `chrTick` ← `playerTick` ← `propsTick` ← `lvlRender` ← `bossMainloop`) but this time **`frames=12962` frozen CONSTANT across ~200 heartbeat dumps / minutes** — a true infinite loop, not the D155 slow-catch-up spiral. 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. | 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).** 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. The N64 was physically VI-bound and never produced `deltaFrames > ~2`. Timing-compensation class, cf. D117/D134. | FIXED (`src/game/frametiming.c`, `#ifdef PORT` — clamp `nextFrameTime` to `FRAMETIMING_PORT_MAX_CATCHUP` = 6). After a hitch the sim just resumes at real-time-ish pace instead of spiralling, exactly as the console did when it dropped frames under load. N64 path verbatim. Confidence: high (stack + arithmetic both point here). porting-notes.md §E. |

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.

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.

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.

| D164 | **Disclaimer / legal screen only draws the first line (D76 root cause, M-31).** `constructor_menu00_legalscreen` (`src/game/front.c:1523`) renders the 12-entry `legalpage_text_array[]` with `legal_text_end = (struct legal_screen_text *)&legalscreen_MRD;` then `do { render; ptr++; } while (ptr < legal_text_end);`. 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). The D68 fixup and the `GE_IMGT` avenue in the brief are both dead ends here. | **FIX PROPOSED, NOT APPLIED** (`front.c` is owned by another agent this session). One-line `#ifdef PORT` in `constructor_menu00_legalscreen`: `legal_text_end = legalpage_text_array + ARRAY_COUNT(legalpage_text_array);` (N64 `&legalscreen_MRD` cast under `#else`). Same linker-layout class as the D75 loop-bound / D142 enum family. Confidence: **high** — mechanism confirmed by symbol addresses. |

| D159 | **Front-end wallet-Bond photo (and other large front-end I4/I8/IA8 textures) render "interlaced" / combed (M-31, user bug RC1 / D149).** The user's menu showed a garbled venetian-blind Bond photo on the folder / mode-select screen; earlier the same model DL walked into garbage (`D146` opcode spam) — that crash is already contained by the D144/D146 guards, so what's left is purely the texture. 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. |

Caverns is one of the larger/more complex levels (cross-ref the D250 "FPS inconsistent" lineage, though D250's own symptom was sustained sub-60fps, not a multi-second total stall, so likely a different mechanism — a one-time heavy room/asset stream-in stall is the leading guess, unconfirmed).

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**`). As N64 `s32` it is 4 B, so `*(Gfx**)&sp54` reads 4 B of the adjacent stack float as the pointer high word → `_g = 0x03e4fca0_70081220` → wild DL write in `texSetRenderMode` (`othermodemicrocode.c:177`) the moment the crosshair raises. §A.

crash class C1: `chrIsNotDeadOrShot` NULL deref on 6 levels (Dam/Runway/Frigate/Statue/Streets/Cradle). D122's `OBJ_TAIL_DESC` zeroed the widened `VehichleRecord/AircraftRecord.ailist` slot (w32), but `prop.c:1764/1786` reads a pre-populated int AI-list id there → `ailistFindById(0)` → `GAILIST_AIM_AT_BOND` → `ai()` runs a CHR aim list with `ChrEntityp==NULL`

|
||||
|
||||
crash classes C3+C6 (Aztec/Bunker2/Surface2): **root cause found (M-16)** — `tools_pc/d88_emit.py:374` assigns a 4-byte literal to an 8-byte slice (`out[dst_o+0x30:dst_o+0x38] = b"\x00…"`, the stan zero-fill in `emit_pad`); every pad/boundpad record silently shrinks the output bytearray by 4 B, and once the tail falls below the boundpad plink string blob, later verbatim leaf writes hit Python out-of-range slice semantics (insert at current end, not relocated offset) → boundpad names drift/truncate (Aztec pad33 `p138d2`→`8d2`) → `stanPackId()` reject → `getposstan()` NULL stan → `setupDoor` leaves door `model=NULL` → crash `propobj.c:13601`. M-14's "propDefs zeros in RAM" was a misread; sidecar propdefs were always correct (M-15) and post-load RAM matches the sidecar byte-for-byte (M-16)
|
||||
|
||||
**Status (from §F table):** **resolved (M-16b)** — line 374 → 8 NULs; all 21 sidecars regen'd; **Aztec `-level_28` now PASSES** (was C3 CRASH). Bunker2 falls through to a separate DOOR-tail `linkedDoor` layout bug (C3 residual)

On PC that pointer widens 4→8B and lands 8-aligned at offset 16 → struct is 24B/6w (N64 16/20). `d88_propdefs.py` emitted them at N64 size via the generic arm → the runtime 8-byte `->next` write clobbered the *next* record's header → propdef walk desynced, command indices drifted ~100, `linkedDoorOffset + arg2` resolved to the wrong record → door `linkedDoor` chain walked into garbage.

crash class C2m (Jungle `-level_37`): fast3d `gfx_sp_matrix` AV on a wild matrix pointer `0x401c68e0` (`gfx_pc.cpp:1046`) ~frame 300, when the first explosion/smoke prop renders. `explosionRenderPropSmoke` builds `gSPMatrix(gdl++, osVirtualToPhysical((void*)&dword_CODE_bss_8007A100), …MODELVIEW)` (+ `applyRoomMatrixToDisplayList`). `osVirtualToPhysical()` is a `u32`-returning shim (`libultra.c:1207`) → truncates the compiled `.bss` symbol's `0x1_00000000` module high word → w1 = `0x40xxxxxx` → `seg_addr()` returns it raw. Same class as D94 (chraction 32-bit ptr truncation), but in a GBI DL word. The projection matrix in the same DL is fine (`get_BONDdata_field_10E0()` is a runtime `0x70xxxxxx` ptr, fits u32); the `gSPDisplayList(&globalDL_0xNNN)` refs are fine (port `Gwords.w1` is 64-bit `uintptr_t`, no macro truncation). ~30 `osVirtualToPhysical(<compiled matrix/vtx symbol>)` sites exist (`explosion.c`, `glass*.c`, `blood_animation.c`, `bondview2.c`) — all latent until that effect first draws.

||||
|
||||
**Status (from §F table):** resolved — `seg_addr()` restores the module high word for any fallthrough w1 in `[0x40000000, 0x70000000)` (module fixed-based at `0x140000000`, no ASLR; DRAM/KSEG0/segmented/phys all handled earlier).

|
||||
intro render triage (M-20): the "intro renders mostly black" item in the M-18/M-19 handoff is **NOT a regression** — it is the D75/D76 parked-cosmetic steady state. M-17 (`9ec6121e`), whose handoff claimed "the entire intro renders — logos → gun barrel → cast", was built in a scratch worktree and captured with the same `GE_PCDUMP="20-900:20"` window: coverage is **pixel-identical** to HEAD `0b5f5d1a` (legal screen 6677 non-clear px / 2.17% on both; centred-logo frames ~7% on both; near-black between). 2D/text/texture layers draw; animated character-model layers (Nintendo-logo transform, gun-barrel Bond, cast models) never appear = D75 exactly. No cheap regression to fix; parked. Secondary: Facility `-level_34` + Jungle `-level_37` re-verify FAILED this pass (boot crash / frame-2 hang) — flagged in LEVEL-STATUS for a clean-machine re-check, not investigated (scope).

**Status (from §F table):** RESOLVED — not a regression, parked (D75/D76, `GRAPHICS-BACKLOG.md`)

## D134 — Frame-2 boot hang / sweep "NO-FRAMES" flakiness — root-caused and fixed (M-22).
|
||||
|
||||
**Frame-2 boot hang / sweep "NO-FRAMES" flakiness — root-caused and fixed (M-22).** `osSpTaskStartGo` (port/src/libultra.c) posted the SP/DP task-done events with `OS_MESG_NOBLOCK` into the scheduler's 8-slot `interruptQ`, which the 60 Hz VI pacemaker thread also fills with `VIDEO_MSG`. A gfx task runs the whole frame synchronously on the sched thread (fast3d); the first two frames take 30-80 ms, so the pacemaker queues several retraces meanwhile. Once the queue is full the RSP-done post is **silently dropped** -> `__scMain` never clears `sc->curRSPTask` -> the client never gets `OS_SC_DONE_MSG` -> `bossMainloop`'s `pendingGfx` never clears -> permanent stall (log: `frame 2 rendered`, then `kernel heartbeat ... frames=2`, retrace queue pinned at `valid=8/8 ret=-1`). Reproduced 2 of 3 `-level_09` boots on an idle machine, i.e. most of what M-13..M-21 wrote off as D117 nondeterminism / machine load. `OS_MESG_BLOCK` is NOT the fix (the done event is posted from the sched thread, the queue's only consumer -> self-deadlock): `portPostEventForce()` drops the OLDEST message (always a stale retrace) and retries, and `portPostVIEvent` now reserves 2 slots. Verified: 6/6 `-level_09` boots reach frame 600 with 0 heartbeats (pre-fix 1/3).

## D135 — Firefight crash — `bgTestHitOnObj` (`propobj.c:8446`) is an unported N64 GBI parser (M-22, WS6 playtest).
|
||||
|
||||
**Firefight crash — `bgTestHitOnObj` (`propobj.c:8446`) is an unported N64 GBI parser (M-22, WS6 playtest).** The object bullet-hit test walks a model's display list command stream with hardcoded 8-byte-N64-`Gfx` byte/word indices (`*(s8*)gdl`, `((u32*)gdl)[1]`, `((u8*)gdl)[5..7]`, the G_TRI4 nibble reads, the backward `G_SETTIMG` scan). On PC the model GDL is the 16-byte `Gfx` layout (`d43_emit.py`, `{u64 w0; u64 w1}`), so every access reads the wrong bytes → the walk desyncs on the first `G_VTX`/`G_TRI1` → `v->coord.x` deref off the end of the DL → AV (`0x709ae02a`, a near-miss past a live DRAM ptr = the §B signature). Triggered by `propobjFindHit` every time a shot ray resolves a hit on an object model (guards' dropped weapons, attached objects, shootable props) — invisible to `level_sweep.sh` (no weapon fire). Two sibling faults seen the same session (`texSelect`/`texSetRenderMode` wild `gdl`, `objFreeEmbedmentOrProjectile` `prop->obj`) are likely the same corrupted-object cascade. PD `bgTestHitOnObj` (`pd_port/src/game/bg.c:3635`) is the fully-ported ground truth.
|
||||
|
||||
**Status (from §F table):** FIXED (`src/game/propobj.c`, `#ifdef PORT` — reads `gdl->words.w0/.w1` shifts). **Second fault, same walker:** after the parser fix the Facility firefight then hit `0xc0000094` (int div-by-zero) at `objHit` `propobj.c:9717` `randomGetNext() % impact_sounds->thing2_len` — the ported texnum-recovery (`*(s16*)(phys(w1) − 8)`) returned a bogus positive `texturenum` (`(u32)` cast truncated a 64-bit `words.w1`; the N64 "texnum 8 bytes before the texture data" layout isn't guaranteed for the port's converted/replaced GDLs) → `g_HitTypeSounds[texnum & 0xf]` picked an entry with `thing2_len == 0`. Fixed: the PORT texnum branch now always returns `-1` (→ `g_HitTypeSounds[0]` = `isnd_default`, `thing2_len == 1`, safe). `texturenum` only flavours the bullet-impact sound/decal, so generic-hit is an acceptable degradation (park with D77). **Follow-up:** the BG room-geometry sibling `sub_GAME_…` (`bg.c:~3373-3646`, walks the D85-widened `ptr_expanded_mapping_info`) has the identical unported parser pattern — latent, fires on shooting walls/floor; not yet ported.

## D136 — Stage-unload crash — `objFree` `obj->prop` reads float garbage (M-22, WS6 Facility playthrough).
|
||||
|
||||
**Stage-unload crash — `objFree` `obj->prop` reads float garbage (M-22, WS6 Facility playthrough).** After D135 cleared the firefight crashes the level is completable; then on teardown `lvlUnloadStageTextData` → `cleanupObjects` (`cleanup_objects.c:42`) → `objFreePermanently` → `objFree` (`propobj.c:994`) → `objFreeEmbedmentOrProjectile(obj->prop)` faults at `:888` (`prop->obj` deref). Real gdb `bt`: `obj` = `0x701bd730` (valid) but `obj->prop` = `0x3e567400405c30c0` — two packed `f32` (~0.21, ~3.44), i.e. a `coord3d` read as a pointer → `ObjectRecord.prop` (N64 `/*0x10*/`, after `inherits PropDefHeaderRecord` + `s16 obj; s16 pad; u32 flags; u32 flags2;`) lands at the wrong PC offset for this object's propDef type, OR the record is undersized and setup's `->prop` store never happened / was clobbered. Same family as D122/D132 (`tools_pc/d88_propdefs.py` per-type record sizing vs the compiled `ObjectRecord`/subtype layout). Type not yet identified — needs a gdb run with a breakpoint on `objFree` to read `obj->type` (`cleanupObjects` frees WEAPON/AMMO/MAGAZINE/COLLECTABLE/MONITOR/RACK/AUTOGUN/HAT/ARMOUR/GAS_RELEASING/VEHICHLE/AIRCRAFT/GLASS/SAFE/TANK/TINTED_GLASS via this path). Mission completes; crash is before the next briefing loads.
|
||||
|
||||
**Status (from §F table):** ROOT-CAUSED → **D139** (it was NOT a layout bug — `cleanupObjects` read the type from the wrong byte on LE and walked off the propDef blob).
|
||||
|
||||
## D139 — Stage-unload crash root cause + fix (M-23).
|
||||
|
||||
**Stage-unload crash root cause + fix (M-23).** `cleanupObjects` (`cleanup_objects.c`) walks `g_CurrentSetup.propDefs` with `(u8)obj[0]` as the record type — correct only because the header word `[u16 extrascale][u8 state][u8 type]` is **big-endian** on N64, so `type` is the low byte. 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. Not a `d88_propdefs.py` layout issue at all.
|
||||
|
||||
**Status (from §F table):** FIXED (`src/game/cleanup_objects.c`, `#ifdef PORT` — `CLEANUP_PDTYPE(o)` = `((PropDefHeaderRecord*)o)->type`). **UNVERIFIED** — the fast teardown test (pause→abort) hit D140 first; `-level_09` unregressed. porting-notes.md §C.

## D140 — Pause-menu crash (M-23 open → M-27 fixed).
|
||||
|
||||
**Pause-menu crash (M-23 open → M-27 fixed).** `bondviewRenderWatch` (`bondview2.c:8604`) → `bondviewTransformManyPosToViewMatrix(g_CurrentPlayer->field_23C, objheader->numMatrices)` with `field_23C == NULL` → `matrix_4x4_copy(src=0x0)` AV. Root cause (NOT "cache never allocated"): `something_with_watch_object_instance` (N64 player +0x230) is a **`struct Model` (0xBC) + its RW-data pool (0xC8) punned into a 0x184-byte hole** (`field_234..field_3B0`); three of those "fields" are Model members the game reads by name — `watch_scale_destination`==`.scale`, `pause_watch_related_adjust`==`.animframe1`, **`field_23C`==`.render_pos`**. `render_pos` IS populated (by `instcalcmatrices` via `subcalcmatrices` at `:8524`), but on x86-64 `sizeof(struct Model)` grows (4→8B ptrs) so `field_23C` no longer overlaps `.render_pos` → reads Model padding (~0) → NULL. Same class as D100 (gait Model) / D102 (weapon Model) / D56 (this very watch Model's pool). Fix: `#ifdef PORT` makes `something_with_watch_object_instance` a real inline `struct Model` + `u32 watchRwPool[192]` in `struct player` (`bondview.h`); `bondview2.c` redirects the 3 named reads to the member via `GE_WATCH_{ANIMFRAME,SCALE,RENDERPOS}` macros (N64 `#else` = the verbatim field). The D56 branch of `sub_GAME_7F07E7CC` drops its `static u8 watchRwPool[0xC8]` for the inline pool.
|
||||
|
||||
**Status (from §F table):** FIXED (`src/game/bondview.h`, `src/game/bondview2.c`; `#ifdef PORT`). Exposed the next watch-render crash → **D141**. `-level_09`/`-level_20` unregressed (3/3). porting-notes.md §A.

**Watch-menu item-model crash (M-27), exposed by D140.** Pressing Start → watch page renders → `set_enviro_fog_for_items_in_solo_watch_menu` (`gunfire.c:1620`) → `modelGetNodeRwData(&model, root)` with `root` garbage → AV reading `root->Opcode` (`model.c:478`). `gunfire.c:1720-1743` walks `bodymodel->Switches[]` (a `ModelNode*` array) with **raw byte offsets** `((u8*)Switches) + j + 0x48` / `+ 0x5c` and `j += 4` — assumes 4-byte N64 pointers. `0x48/4=18`, `0x5c/4=23`, `k=j>>2=0..4` → intent is `Switches[18+k]` and `Switches[23+k]`. PC's 8-byte stride makes the raw math read misaligned garbage → bogus non-NULL `ModelNode*`. porting-notes.md §B (raw hardcoded stride into a pointer array, cf. D128). Fix: `#ifdef PORT` uses `bodymodel->Switches[18 + (j>>2)]` / `[23 + (j>>2)]`.
|
||||
|
||||
**Status (from §F table):** FIXED (`src/game/gunfire.c`, `#ifdef PORT`). Watch page now renders (weapon page verified — mirrored text D114/D116, dark weapon model D75, both parked cosmetic). `-level_09`/`-level_20` unregressed.

## D150 — Watch objective/briefing page crash (M-28).
|
||||
|
||||
**Watch objective/briefing page crash (M-28).** Opening the watch → BRIEF (any subpage) or OBJECTIVES page → AV in `strcat` (`str.c:25`, `Rdi/src = 0`). The pages assemble their display text with `strcpy`/`strcat(buf, langGet(id))` (`options.c:3940-4068`, `front.c:3538-3562`, `propobj.c`). `langGet()` returns **NULL** on PC for a string bank the menu flow never loaded (D129/D143 guards — briefing/objective banks in the in-level watch flow), so `strcat(buf, NULL)` derefs NULL. 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. Same philosophy as the D143 textRender/textMeasure NULL guards, one layer down. Inert on N64.

**Status (from §F table):** FIXED (`src/str.c`, `#ifdef PORT`). Build green (`ntsc-final`); `-level_09` 600+ frames @ 91.67% unregressed. Watch-page repro is interactive — user to re-verify. porting-notes.md §C.

## D151 — Watch data all blank — objectives / mission background / M / Q / Moneypenny (M-28, user bug report).
|
||||
|
||||
**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`).
|
||||
|
||||
**Status (from §F table):** 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`). No converter change, no sidecar regen. `nextentry`/`difficulty`/`unkD` unchanged. porting-notes.md §C. Build compiles clean; interactive re-verify pending (open the watch in any level).

## D130 — crash class C2 (Facility `-level_34`, Runway `-level_35`):
|
||||
|
||||
crash class C2 (Facility `-level_34`, Runway `-level_35`): `import_texture_i8` AV on a wild texture pointer (`0x72181ee8`), baked into the HUD glyph DL by `gDPLoadTextureBlock(gdl, curchar->pixeldata, …)` when the level-title string ("Chemical Warfare Facility #2") renders `#`/`"`. 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.
|
||||
|
||||
**Status (from §F table):** resolved — stage all 6 N64 fields in a local `f[6]` before writing any. Facility + Runway now PASS (16→18/21). Probes reverted.
