feat(phase-7): Gen1 close-out — matching loop industrialized, PsyQ libs linked, LZSS matched (v1.7.0)
- reports (Task 3): tools/{progress,difficulty,dup_report}.py + make report/sig-refresh
(deterministic digests); harvest to 43 REAL matches incl. LzssDecodeSector
- per-module -O0 split (Task 5.5): src/boot.c + Makefile per-file CC1FLAGS (cookbook §6)
- PsyQ SDK linking (sessions C-G): split/build/identify/link/integrate pipeline
(tools/psyq_*.py, make_libgs.sh, ld_interleave.py, split_src_region.py) — libcd (18 obj)
+ FULL libgs (31 obj / 6 blocks) linked BYTE-IDENTICAL from real PsyQ 4.0 libs; byte-
identical with or without the SDK objects (stub fallback); cookbook §7/§8/§9.1-9.5
- LZSS MATCHED byte-for-byte (session F): §5a cross-jump barrier + §10 regalloc/schedule
idioms, ground-truthed against pinned gcc-2.7.2 source (the Gen1 LZSS gate)
- file-loader cluster: 6 matched + 5 NON_MATCHING-drafted (CdReadStateMachine,
CdReadSectorReadyCB, StreamLoadStateMachine new this session, valid under -DNON_MATCHING);
SaveLoadRoutine DEFERRED to Q#5 (save/memcard, documented stub)
- README Gen1-complete; worklog preserved -> phase-ends/logs/Phase7.md
- rules R17 (web-research compiler quirks), R18 (plain-English session summaries),
R19 (preserve phase worklog out of load order)
- MILESTONE: Gen1 EXIT confirmed — byte-identical build, 43 matches incl LZSS, 7 zero-
regression sessions, loader cluster matched/drafted, overlay map emulator-proven
- bumps project version 1.6.0 -> 1.7.0

feat(phase-6): compiler pinned + matching loop proven (14 matches) — LZSS to Phase 7
- splat.us.exe.yaml: text subseg asm->c (INCLUDE_ASM scaffold); include/common.h
(committed prelude); Makefile c-rule cpp->cc1->maspsx->as + -Map
- PIN (G8): gcc-2.7.2-psx -O2 -G0 -mips1 -mcpu=3000 -mgas -msoft-float -fgnu-linker
+ maspsx --aspsx-version=2.56 --expand-div; byte-exact on func_80018F20 +
instruction-identical across 3 idiom classes; --expand-div REQUIRED for div/rem
(SETUP.md §5.4 PINNED, Makefile MASPSX_FLAGS)
- harness: diff_settings.py (asm-differ mipsel object mode), tools/decompile.py
(m2c wrapper), tools/permuter/ (decomp-permuter harness + objdump shim), expected/
- 14 real functions matched (asm-differ score 0): func_80018F20 + 13 accessors;
+14 splat-auto empty no-ops; make check BYTE-IDENTICAL throughout
- 2 instruction-identical near-misses guarded NON_MATCHING (func_80015A74 scheduling,
func_80016714 phantom frame) -> decomp-permuter candidates
- flywheel: docs/matching-cookbook.md, memory + CLAUDE.md step 5 (consult+evolve), R16
- requirements-python.txt: venv freeze (pycparser<3.0 pinned — permuter needs plyparser)
- LZSS spike: needs jump-table-in-rodata workflow (102 tables, mixed blob) -> Phase 7
- venv: asm-differ + permuter deps installed
- bumps project version 1.5.0 -> 1.6.0

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
