feat(phase-7): -O0 split + 4 matches (42 real) + libcd.h — session B checkpoint
- per-file -O0 mechanism: split text c-subseg into boot@-O0 (src/boot.c) + 800@-O2
via splat resegmentation + Makefile target-specific CC1FLAGS; the boot/main/
game-mode-dispatch module (0x80010000-0x800123F0) is -O0, not the pinned -O2
(per-module compiler mixing, SETUP §5.5). Regression-gated byte-identical.
- 4 byte-matches (38->42 real, make check BYTE-IDENTICAL throughout): GameModeDispatch
(-O0 register-ptr far member), DebugMenuHandler (-O0 reserved-slot local), CdQueueBusy
(-O2 if/else order + branch polarity), CdReadRequest (-O2 early-return fall-through)
- PsyQ infra: include/psyq/libcd.h (CdlLOC/CdlFILE from the .gdt) + 4 named symbols
(CdSearchFile/CdPosToInt/CdIntToPos/VSync) in symbols.us.txt; func_* stubs renamed
- loader cluster non-jtbl COMPLETE (6 matched + 2 drafted): NON_MATCHING drafts of
LoaderInitFileTable + ResourceLoadStateMachine (logically faithful, residuals in-source)
- tooling: progress.py/difficulty.py fixed for the multi-file split (glob src/*.c, all
asm dirs, skip forward-decls); deterministic; 42 real / 4 NM
- flywheel: matching-cookbook §6 (-O0 detection + idioms), §7 (PsyQ types/symbols), T4
- build byte-identical 143dbb89f34491258bbc27810d0a12ec8b43a8dd from a full clean cycle

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
