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

feat(phase-3): file-loader & overlay-map RE + PCSX-Redux runtime oracle
- RE'd the full file-loader/overlay subsystem in Ghidra via MCP: CdReadRequest ->
CdReadStateMachine (hand-rolled CdControl SeekL/ReadN reader, NOT PsyQ CdRead);
LIST.CD RAM cache cdFileLocTable + ResourceGetCdLoc/resourceIdMap lookup; LZSS
staging buffer 0x80079A70; loadDestPtrTable; ~50 symbols named (T1-T5,T8)
- T6b MILESTONE: resident blob @0x800CEDF8 + location overlay @0x80128158 proven
byte-identical (sha1-equal contiguous prefixes) vs live PCSX-Redux RAM; blobs
imported into Ghidra (ImportOverlay.java); overlay-map table -> memory-map.md §4.3
- PCSX-Redux runtime oracle: Windows-native build, WSL reads RAM via the web API
at 172.17.208.1:8081; ledger #4 resolved
- live-verified player/time state: gold(/10) HP BP day hour tiredness boss-HP;
save-header template (Q#5) + debug-menu dispatch (Q#9: DEBUG.BIN path is dead)
- overlay map: 13 area-states across SC01/02/03, 2 duplicate pairs, location x
chapter keying, free-roam vs menu-hub granularity
- resolves Open Q#1/#3/#4/#5/#6/#8/#9/#12; corrects SLUS-90029 (FF8 demo, not BFM)
- 2 US prototypes acquired + CRC-verified (Aug-31 1369DE07, Sep-8 5C24728E)
- rules R9 (verify persistence), R10 (>=3-datapoint live verification),
R11 (runtime oracle Windows-native, bridged to WSL)
- bumps project version 1.2.0 -> 1.3.0
