* D217 (M-90): align texpool arena bases to 8 bytes on PC — fixes solid wrong-colour weapon/model CI tiles
Root cause: texAlignIndices pads CI index rows to ABSOLUTE 8-byte
boundaries, and model-DL G_LOADTLUT palette offsets are a formula that
only matches the real layout 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 weapon-pool bases land %8==4 (e.g. FACILITY). Every palette in a
misaligned pool then sits 4 bytes early inside its allocation while the
draw reads the N64 offset: the PP7 grip's count=1 TLUT lands on the next
tenant's 8-byte header slot (texnum=26 -> LE s16 -> 0x1A00 = the green),
and larger loads read a 2-entry zero pad then the real palette (the M-86
'leading zero pad' tell). BUNKER1 was clean only because its bases
happened to be aligned.
Fix: texInitPool rounds the arena base up to 8 under #ifdef PORT; end
unchanged (pool loses <=7 bytes). No-op on N64 where bases were already
aligned. ABI/layout-class edit per AGENTS.md rule 2 narrow exception —
no game logic touched.
Verified: FACILITY 188/188 decodes %8==0, draw reads pal0=0001 (was
1a00), 0 green pixels in frames 250-450 (pre-fix ~1300); BUNKER1 + DEPOT
still clean; full verify.sh sweep 21/21 PASS. Pending: human playtest
eyeball of the M-87 weapon matrix (closes defect 1). Defect 2 (CI cache
content-hash key, fix/d217-model-texture-palette) remains separate/parked.

* docs(D217): M-92 - human playtest of PR #47 confirms PP7/PPK/watch fixed; AK47 + NPC-held world-model weapons are a distinct, still-open white-texture residual

* docs(D217/D228): M-97 human playtest - green FIXED, AK47 white patches split out as D228
Second independent playtest (after M-92) of PR #47 on FACILITY, this
time with the branch merged up to date with main. Confirms the same
split the M-90 write-up predicted: PP7/PPK grip+hammer, watch face and
world-model green are all fixed by the texpool alignment; NPC-held
AK47 white missing-texture patches are untouched.
White is a different signature from wrong-colour -- a wrong palette
binds a real TLUT with wrong contents, white means the texture was
never decoded/uploaded at all -- so this is a separate mechanism, not
an incomplete fix. Split out as D228 so D217 can close on the green
mechanism it actually describes instead of carrying an unrelated open
failure mode indefinitely.
D178 (briefing objectives blank) and D149 (front-end 3D models garbled) -
user-verified fixed, closed.
D182 (file-select round-trip degradation) - still broken, confirmed.
D77 (no music) - rescoped: music plays on intro/cast-roll/main menu, only
missing in-level. Points at the level-start music cue, not the
mixer/playback layer.
D221 (new): SELECT FILE mouse hit-box vertically offset from the visible
box (click below a file to select it) under the shipped default
MouseCaptureMode=1 - distinct from D192's clamp-range bug under legacy
mode 0, likely same front-end grid-coordinate family.

D176: skybox still glitchy broadly (not just Surface); Cradle named as
still showing solid black where sky/backdrop should be. Confirms (a)
never landed a verified fix.
D173: Bond hover/float cutscene glitch still present.
D148/D160: new specific instance - Bond spins in circles in some
cutscenes (end-of-Cradle Trevelyan-falls cutscene named) - likely same
actor-position/anim-root cause as D173, manifesting as bad rotation.
Claude-Session: https://claude.ai/code/session_016TaKy6AAsVUTfjkhrX6CjG
D217: two defects found. (1) The visible green grip/hand is upstream of
fast3d — the grip's count=1 model G_LOADTLUT is fed different source bytes
per level (Facility 1a 00 -> 0x1A00 green; Bunker 00 01 -> black); every
larger model TLUT carries a 2-entry leading zero pad, so the port's
model-TLUT source pointer is likely 4 bytes low (or a d43_emit.py blob
offset). fast3d byteswap is correct (proven by Bunker). (2) A real CI
texture-cache collision (no palette-content key) — fix landed on branch
fix/d217-model-texture-palette f6fc0399 (palette FNV-1a hash in the CI
key); owes a 21-level sweep; does not fix (1). porting-notes + graphics-
backlog updated.
D211: aim-zoom compose verified correct by construction (single post-lerp
multiply at the fr.c chokepoint; zoom ratio preserved). Only a low-risk
cosmetic eyeball remains (viewmodel/frustum-cull use unscaled fovy).
Claude-Session: https://claude.ai/code/session_016TaKy6AAsVUTfjkhrX6CjG
gunRenderFirstPersonGunModels built its ModelRenderData with
renderdata = *(ModelRenderData *)&D_80035CC0;
a reinterpret that reads the lone `u32 D_80035CC0 = 0` and continues into the
next declared global `u32 D_80035CC4[] = {1, 3, 0, ...}` (gun.c). On N64 that
yields { basemtx=0, zbufferenabled=1, flags=3, rest=0 } because the linker
lays the two globals out contiguously in declaration order and pointers are
4 bytes. On x86-64 it breaks twice: ModelRenderData's pointer members widen
4->8 B (so `flags` is no longer at struct offset 8) and C guarantees nothing
about the two globals' placement. Measured (GE_DVM=1, BUNKER1): flags == 0,
which gates every weapon-model DL node off in modelRenderNodeGundl
((renderdata->flags & 1)) -> subdraw emits 1 gfx command instead of ~150 ->
no gun visible while playing.
All three VIEWMODEL-RESEARCH.md ranked suspects were ruled out first by the
same probe: field_87F==1, RootNode valid, numRecords 22 < pool 192, node walk
visits 24+ valid DL/SWITCH/BSP nodes.
Fix: #ifdef PORT -> set the fields explicitly (zbufferenabled=TRUE; flags=3);
N64 line verbatim under #else. ABI/layout only (D3x class), no logic change.
Verified (headless): GE_DVM=1 post-fix shows flags=0x3 and the weapon subdraw
now emits 153 gfx commands (was 1); bunker1 framediff worst_cell 12.2 -> 28.5
(gun renders in-frame); Dam/Facility/Bunker1/Archives/Cradle/Aztec sweep
crash-free. Owed: one BUNKER1 eyeball; the bunker1 golden needs re-baselining.
GE_DVM gate+render probes left in, env-gated (cf. GE_D193*).
findings.md D215 + index; GRAPHICS-BACKLOG + VIEWMODEL-RESEARCH marked resolved.
Real particle records (assets/oddtextures.c globalDL_0x078..) DO set
gsDPSetCycleType(G_CYC_2CYCLE); GE_D172=1 probe confirms fast3d applies it
(particle combine fc26a004 logged at cycletype=2CYC). Both the 0xB9-abort
and the cycle-type hypotheses are now dead. Bug is the G_CC_INTERFERENCE
two-tile combine / TEXEL1 path (IA8 smoke x RGBA16 fire @ tmem 0x188).
Probes (#ifdef PORT, GE_D172=1, inert otherwise):
- gfx_pc.cpp G_SETCOMBINE: distinct combine + active cycletype
- gfx_pc.cpp gfx_sp_tri1: tris with cyc2 combine drawn at cycletype!=2CYC
Needs a display capture to go further (headless can't see particle colour).
0xB9 == G_SETOTHERMODE_L in this non-F3DEX2 build (G_IMMFIRST-6); fast3d
handles it as gsDPSetRenderMode. -level_09 sustained-fire run: zero D146
aborts, zero warnings. Re-scoped to the 2-cycle/cycletype hypothesis
(records never set G_MDSFT_CYCLETYPE -> use_2cyc==0 on PC -> TEXEL1
garbage -> magenta/cyan).
Cloud tile is s_skywaterimages[0] = 64x64 IA8, G_TX_WRAP -> it tiles.
GE's screen-space textured-quad idiom is tc = width<<5 (glass2.c:678), so
skyPortRenderPoly's *32.0f scale was correct; the bug was (s16) overflow on
the +/-20k-texel horizon S/T (unk20/unk24 are texel coords, not fractions).
Fix: fold every vertex of one primitive by the same multiple of the 64-texel
tile period before scaling. Inter-vertex deltas (hence the interpolated
cloud texture) are preserved; magnitudes stay in s16 range. Exact for any
triangle whose S/T span is < ~1000 texels -- everything except tris
straddling the horizon line, which are Defect 2 (adaptive tessellation).
sky.c #ifdef PORT only; N64 path unchanged. Builds clean; bunker1 + statue
verify PASS, no crash. UNVERIFIED VISUALLY -- owed: one -level_22 screenshot
(D176a-SKY-NOTES.md 'Verification ask').
Also: rebased onto main (porting-notes.md conflict resolved).
Update the public-facing docs to the M-49 state (v0.1.0 alpha, first
full-campaign playtest: 19/21 missions completable, D191 crashes Bunker ii
+ Statue, D193 AI pacing is the top flaw).
- README: lead with what it is + status, research angle second; new
Quick start section; Status/Download rewritten for the alpha + dual
platform; "By the numbers" refreshed (~3 weeks, ~320 commits, ~190
findings, ~49 sessions, 69 PORT files).
- .github/release-notes.md: v0.1.0 title + known-issues rewrite.
- .github/social-preview.html: status/stat lines (regen + re-upload the
PNG separately).
- docs/index.md, docs/dev/LEVEL-STATUS.md: M-49 status.
- docs/dev/findings.md, docs/dev/GRAPHICS-BACKLOG.md: D191-D197 +
D148/D170/D173 M-49 escalations.
Hygiene:
- Fix the `&` literal in internals.md H1.
- Repoint two ../README.md links that 404 on the Pages site.
- Standardise British -> American spelling across the public docs
(behaviour->behavior, colour->color, catalogue->catalog,
centre->center, etc.). Deep internal logs left untouched.
- .gitignore: document the local-notes convention (docs/HANDOFF.md,
docs/BACKLOG.md, and a new docs/dev/notes/ drop for roadmaps and
session plans) so it survives a fresh clone.
- findings.md / GRAPHICS-BACKLOG.md: -level_22 (Statue, night) is a clean
no-input headless repro of the D176(a) black sky — bare boot, frame ~360,
upper half pure black. Best verification target for the RDPHALF sky-tri
decoder. Note -level_36/-43 intro cams face the terrain (not a sky test
without GE_INPUTSCRIPT); -level_29 top-of-frame is dim, not black.
- GRAPHICS-BACKLOG "D74 wrap-block": struck through — the dead-code / OOB
in-vertex-loop wrap block was reworked and hoisted to a per-texunit
pre-wrap window behind Video.WrapFix at M-30 (RC3/D167). No longer latent.
Not root-caused; narrowed substantially. Headless -level_36 + GE_D176 probe
(bgfog.c fogLoadLevelEnvironment, sky.c skyRender):
- Environment data is CORRECT: fog_tables[] matches Id=36, Sky.Clouds=1,
warm CloudRGB=240,120,30, SkyImageId=0. Not a serialized-struct
byte-order bug (fog_tables is a compiled C initializer).
- skyRender runs the cloud path; corner classification is correct
(switch case 12, "sky is top half").
- But skyRenderTri/skyRenderFull emit nothing - not even the env->RGB
fill shows. Sky polys degenerate after projection, culled, or the
skywaterimages[0] bind is failing.
Next (findings.md "D176(a)"): probe sub_GAME_7F097388 projected coords;
verify skywaterimages resolves on PC (image_bank.c GIMG offset 0xFB4);
fast3d sky-tri trace; cross-check Dam/Statue exteriors.
GE_D176=1 probe left in tree (#ifdef PORT, env-gated, inert). Build
240/240 links clean; -level_09 framediff 3/3.
Headless GE_PCDUMP (-level_36, GE_STARTMENU=10) + static read of the
implicated port code. Two headline findings:
- The "comb interlacing" (D176b, D182-2) is NOT the D159 family.
texSwapAltRowBytes is a full #ifdef PORT no-op (image.c:2199) and
cannot cause anything. Real cause: gfx_pc.cpp import_texture_* assume
line_size_bytes == full_image_line_size_bytes and shear non-PoT /
sub-rect tiles into diagonal noise. New "Family A". Backlog D176/D182
corrected.
- D178 briefing objectives are BLANK, not wrong-listed: header renders,
then just "a." with no objective text. That is the D143/D151
langGet-NULL blank-text family ("Family B"), not a propDef walk desync.
docs/dev/M-36-TRIAGE.md: full family table (A fast3d texture pitch,
B string bank, C D75 models [defer], D blood/particle, E transient
hang [defer], F misc). Recommends Families A and B as the two
high-ROI targets, disjoint enough for two subagents.

- building.md: document the d43_emit.py / d69_emit.py sidecar generation
as an explicit required step (4), split Run to step 5. A plain clone
needs no ROM to build but the sidecars are required to run (D179).
- GRAPHICS-BACKLOG.md: expand D176 (Surface exterior: black sky +
comb-interlaced tree-line, screenshots) and add D182 (SELECT FILE
background degrades after navigate-away-and-back: Bond image stops
drawing + comb interlacing). Both observed this session, not fixed.
D176(b) and D182(2) interlacing share the D159 texSwapAltRowBytes
family recurring on texture re-import.
- docs/img/bugs/: d176 our-build vs reference, d182 backout capture.

New observed-but-not-investigated entries from user QA:
- D173 third-person Bond model spawns too high (level start + Cuba credits)
- D174 no visible blood effect (likely unverified D120 decal fix)
- D175 in-game stutter/brief hang on door open (Runway, Surface)
- D176 skybox broken on Surface
- D177 ladders non-functional — progression blocker, high priority
- D178 pre-mission briefing objectives listed incorrectly

- README: attract-mode stills + demo GIF as the hero row, status/warning
callouts, metrics table, "Contents" index, doc-index table; simplified
the two-agent workflow diagram (LR -> TD, fewer edges) for GitHub web
- Table-of-contents indexes added to internals.md, porting-notes.md,
agentic-development.md, AUDIO-PLAN.md
- CI: add Windows/MSYS2 build job, minimal token (contents: read),
persist-credentials: false, concurrency group; run on main + master.
validate job regenerates the US ROM-asset symbol file only and configures
ntsc-final (PAL/JP need a region ROM; no ROM is used in CI)
- .github: SECURITY.md, issue forms + chooser config, PR template,
labels.yml, dependabot (Actions, monthly)
- Do not track the proprietary SGI IRIX IDO toolchain or SGIImageViewer.exe;
document in SetupGuide.md / building.md how to obtain IDO for N64 ROM
builds (the PC port does not need it)
- Stop tracking two committed *.pyc files; drop stale screenshots and a
redundant .gitignore line; misc doc cross-reference fixes

Built the migrated tree (MSYS2 mingw64 + ROM + sidecar regen) and ran
-level_09 with GE_PCDUMP: HUD text and the exit arrow now read
right-side-up. D114/D116 confirmed as capture artifacts.
- tools_pc/golden/*.png regenerated from a fresh correctly-oriented run
(replaces the stopgap in-place flip); stray v*.png removed
- D75 shrunk: with upright captures the gun-barrel Bond RENDERS fine
(walk + fire) -- the "absent" reports were the flipped capture. The
Nintendo logo is genuinely broken (renders as 2 white blobs shifted
left -- a real logoinst transform bug, not a flip). Cast roll not
re-captured.
- D169 entry -> FIXED with the build/verify note

gfx_opengl_dump_bound_fbo wrote glReadPixels output (GL bottom-left
origin) straight into a top-row-first P6 PPM, so every GE_PCDUMP / F12
capture was upside-down. This is the entire source of the D114/D116
"HUD/text X-mirror" - four sessions chasing a fast3d mirror that never
existed, misreading inverted screenshots of asymmetric content. The
developer confirms the game renders correctly on real hardware.
- writer now emits rows top-to-bottom
- tools_pc/golden/*.png flipped in place to match + golden/README.md
- D114/D116 reclassified as capture-orientation artifacts (not deleted);
D75 "logo mispositioned" / RC1 "photo 180 deg" flagged for re-judging
- annotations in findings.md, GRAPHICS-BACKLOG.md,
TEXTURE-GLITCH-ANALYSIS.md, porting-notes.md D2, GE-ENV-PROBES.md
Not runtime-verified (migrated tree has no ROM/toolchain) - needs a
fresh capture to confirm text reads normally.
