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-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-7): matching reports + 24 matches (38 real) — session A checkpoint
Mid-phase checkpoint (Drew-directed; phase NOT closed — R8 exception).
- reports (Task 3): tools/{progress,difficulty,dup_report}.py + `make report`
(deterministic) + `make sig-refresh`; authoritative baseline 38 real / 2050
matchable; empties audit 42/42 genuine jr;nop; docs/{progress,difficulty,
duplicates}.md digests
- matches (Tasks 4-5): +24 byte-identical (22 accessor leaves via the harvest
pattern + ResourceGetCdLoc + LoaderResetReadState); make check BYTE-IDENTICAL
throughout (143dbb89...)
- config/symbols.us.txt: declare func_80047CAC (R15) — fixes a latent
non-reproducibility (spimdisasm 1.41.0 auto-detect of an 8B inter-fn blob was
unstable across clean extracts; the committed Phase-6 baseline did not
deterministically rebuild)
- Task 1 rodata-island foundation: investigated (migration co-locates jump
tables + resolves refs, but byte-identity blocked by splat global-migration +
contiguous linker placement vs BFM's monolithic segment) -> DEFERRED to Task 2'
with a candidate fix; full findings in phase-ends/CURRENT_PHASE.md
- phase-ends/CURRENT_PHASE.md: reordered plan, loader-cluster triage, per-session
green-check log (1 of >=3 needed for the Gen1-exit milestone)
