Drew T 0265712916 feat(phase-33): B1 make disc-extract — the rom->decoder step in the build: extract.py --expect-manifest (compare against the committed oracle, never write it; mismatch -> .run/extract/ + diffs, exit 1) + --allow-missing-audio (explicit PARTIAL for Track-1-only dumps); disc-extract = probe (0.7 s no-op) -> disc presence -> redump SHA1/CRC32 -> extract+compare -> verify (15.7 s full); extract/extract-all call it; check-env WARN-on-absent EXE + oracle self-consistency; help rewritten; the 4 splat preset headers TRACKED (clean keeps them); .gitignore re-tightened to H1 (dumps/*.bin, ghidra/, tools/psyq/, session archive/, ghidra-ext zips, brave.exe; EXE re-include dropped); controls: no-disc exit 2, truncated disc FAILs with the oracle untouched, regenerated tree byte-identical to the previous (1,801 files) 2026-09-06 19:02:34 -06:00
Drew T 3207d52491 feat(phase-3.5): prototype research spike — go/no-go (protos don't accelerate Gen1 matching)
- extract_proto_exe.py: subdir-aware proto main-EXE extraction (reuses iso9660); extracted
  sep8 SLUS_007.26 (413,696 B) + aug31 MUSASHI/USA_DEMO.EXE (415,744 B, base 0x80018000)
- ghidra_import.sh: reusable headless import; both protos imported into the bfm project
  (sep8 1726 funcs, aug31 1737 funcs, both PsyQ 4.0.0), R9-verified
- DumpFunctionSignatures.java + match_protos.py: 3-tier (exact/norm/seq) cross-binary
  correspondence; MIPS normalizer validated by anchors
- FINDINGS: (T2) no debug symbols in either proto — Hidden Palace "no symbols" VERIFIED;
  recon "Sep-8 less-stripped" REFUTED by per-file byte compare. (T3) Sep-8 99.6% byte-identical
  to retail (only 3 funcs differ: DebugMenuHandler, CdReadSectorReadyCB, SaveLoadRoutine);
  Aug-31 66% norm-identical, 862 1:1 correspondences. (T4) demo shares retail's 18-entry
  game-mode dispatch architecture but the handler code diverged — Q#10 resolved
- VERDICT (docs/proto-correspondence.md): NO-GO as a Gen1 label/symbol accelerator; GO to retain
  Sep-8 (Phase-6 compiler corroborant) + both (Gen2 assets); proto-side labels in
  config/symbols.proto-{sep8,demo}.txt (R13-tagged, never feed symbols.us.txt)
- reorg extracted/ into per-ROM subfolders (extracted/retail/, extracted/proto/); nested
  gitignore allowlist; extractor defaults updated; manifest --verify PASS
- memory-map.md: Phase-3.5 block + demo dispatch anchors; Q#10 RESOLVED; §5 proto notes VERIFIED
- ghidra_mcp_start.sh: PROG arg to serve a prototype
- rules R13 (proto-provenance/confidence tagging), R14 (verify recon counts vs bytes)
- bumps project version 1.3.0 -> 1.3.1

Drew T b6ea3a2747 feat(phase-2): deterministic disc/.CD/PAC/LZSS extraction pipeline
- extract.py: one-command full-disc extraction (27 files: 24 Track-1 verbatim
  + 3 .DA as raw CD-DA audio from tracks 2-4) over the frozen iso9660.py
- cd_archive.py + pac.py: .CD TOC walker + PAC splitter, {index}.{type} naming
  (no collisions; 447 sub-files, 1189 entries), SQV detection (98)
- lzss.py: game-semantics decoder (pos==0 terminator, -1 bias) + 5 unit tests;
  138 type-4 decoded clean (0 warnings)
- manifest.py: deterministic JSON-Lines manifest (1801 artifacts) + --verify
- crosscheck.py + tools/brave-CUE/posix_shim.h: build CUE's brave from source
  (GPL untouched), byte-compare; 1484 raw identical, 138/138 type-4 F6
- docs/formats.md: F5 counts (SC02=43), F2 refuted, F6 resolved, F1 type-7=139
- docs/effort-map.md + CLAUDE.md: Effort-map check rule (R7), Ultracode fix
- .gitignore: /extracted/* + !manifest/EXE exceptions; brave _build/
- install gcc 13.3.0 for the oracle
- milestone: one command extracts the full disc; MAIN.CD=49 sub-files; decoder
  agrees byte-for-byte with CUE up to the game pos==0 terminator; zero ROM
  staged; project version 1.1.0 -> 1.2.0

Drew T de7f015436 feat(extract): ISO9660/MODE2 disc reader + SLUS_007.26 extractor
Reusable iso9660.py (Phase 2 foundation) + extract_exe.py with --list and --verify-disc. Adversarially verified: extracted EXE SHA1 143dbb89f34491258bbc27810d0a12ec8b43a8dd (413696 B), and --verify-disc confirms Track-1 SHA1 b44f0f0a19936f23b26188b658e13201a6a9c211 == redump (dump is canonical).
