Prepare for public release

- README, LICENSE (MIT for the port layer), NOTICE, CONTRIBUTING.
- Restructure docs: internals.md, porting-notes.md, dev-process.md +
  dev/agentic-development.md (the research write-up), dev/ (raw record).
- Replace decomp status-badge CI with a PC-port validate workflow.
- Remove session/agent scaffolding and stale planning docs from the tree.
- Add .gitattributes (normalize line endings to LF); add screenshots.

The pre-2026-08 history is the GoldenEye 007 decompilation by Larry Ficken
(KholdFuzion) and contributors, preserved unchanged. The PC-port work from
2026-08-17 on is mine.

+# GRAPHICS-BACKLOG — known cosmetic / rendering issues
+
+Deferred below level-progression and crash work (user priority, M-11).
+Minor graphical glitches are acceptable in the current state. Fix these
+once the game is playable start-to-finish without crashes.

+## Open
+
+| ID | Symptom | Status / notes |
+|----|---------|----------------|
+| **D114/D116** | HUD text + ammo digits render each glyph individually X-mirrored (screen positions correct, texture content flipped). Likely also explains "inverted" guard skins / mislocated door props. | Root cause NOT found after 4 sessions (M-6/7/8/11). Every stage `textRenderGlyph`→GBI→fast3d→`buf_vbo`→GL runtime-verified non-mirrored (`GE_D116` `[D116/vbo]` probe). Contradiction unresolved. **Next attempt requires a RenderDoc/apitrace capture of one glyph texrect, or the asymmetric-1-texel-texture experiment** — do NOT re-run the static trace, and do NOT apply a global texrect S-swap (mirrors the whole screen). |
+| **D74 wrap-block** | `gfx_pc.cpp:1546/1551` PORT block is dead code: guard `cms & G_TX_WRAP` with `G_TX_WRAP==0` is always false; and it indexes per-texunit `[2]` arrays with the vertex index `i` (0..2) → OOB if reached. | Latent. Harmless for CLAMP glyphs; could affect wrapped textures on triangles (room panels, model skins). Fix: `cms == G_TX_WRAP`, and compute the tile window once per tile not per vertex. Verify against `tools_pc/golden/` after. |
+| **D75** | Nintendo logo mispositioned; gun-barrel Bond model absent; cast-roll character models absent. (Rareware logo OK.) | Front-end 3D model path. Partially overlaps D114 (shared mirror on asymmetric content). Triage plan in `findings.md` §F D75. |
+| **D76** | 2D disclaimer screen only partially drawn. | §F D76. |
+| **D77** | No audible music on PC. | Phase 3 (audio). §F D77. |
+| **D116 (HUD)** | (subset of D114) proportional-font strings + ammo counter mirrored. | Same root cause as D114. |
+| **D148** | Level-end cinematics don't play. Dam: hitting the exit trigger should show Bond rappelling down the dam (the bungee jump); instead it cuts straight to the mission-complete report. | Scripted cutscene / cinematic-camera + Bond rappel anim. Found M-27 during the first full Dam→Facility playthrough. Progression is unaffected — the report and next briefing load fine. **M-31 (§F D160):** static-traced the Dam end ailists (`ai_24`→`ai_17`, `camera_switch`→`CutsceneRecord` type-46 lookup). Diagnostic `GE_D160=1` shipped (`c95713f5`) — user runs Dam to the exit with it set; the trace pins whether the cutscene AI runs, and whether the propDef-index walk (D122/D132 family) hands `camera_switch` a bogus cutscene record. Leading hypothesis: propDef `sizepropdef` stride desync (medium confidence), not D75 anim-model. |
+| **D149** | Front-end MISSION COMPLETE / mode-select 3D models (dossier, wallets) render as garbled full-screen geometry or not at all — one of the compiled sub-DLs (seg5+0x9ee4) is malformed, D146 now skips it instead of aborting. | D75 family. §F D146. |

+## Resolved (for reference)
+
+- D70–D74: intro-logo pixels (Rareware logo renders correctly).
+- D103: viewport / native-resolution half-frame.
+- D105: room geometry Z-buffer never cleared (`G_CLEAR_DEPTH_EXT`).
+- D106: sky-void through doorways (portal near-plane min>max).
+- D107: blurry ceilings/wall-panels (LOD mip tile fabrication).
+- D112: skeletal models were "3D lines" (`d43_emit.py put_f32` byte order).
