- 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

# Regenerate the curated libgs object dir (.run/obj40/libgs_used) for the Phase-7 FULL-libgs
|
|
# integration (Makefile LIBGS_ELF). SDK-derived + gitignored, like .run/obj40/libcd; the build is
|
|
# byte-identical WITH or WITHOUT it (the stubs reproduce the same bytes), so this only matters to a
|
|
# developer who wants the real SDK objects linked. Needs the LIBGS ELF objects from
|
|
# tools/psyq_build_libs.sh LIBGS (which needs tools/psyq/lib40/LIBGS.LIB from the DTL-S2002 redump).

# GS_001 (the 1536 B gap before block 4) is EXCLUDED — psyq-obj-parser packs its scattered PSD*
|
|
# commons into .bss referenced via .bss+offset and 35 words differ at the global-zeroing run
|
|
# (cookbook §9.1 hard case); it stays an asm stub (gsgap3) and reproduces its bytes.
|
|
# The list is DISAMBIGUATED (session E): psyq_identify reports byte-identical-.text aliases — keep
|
|
# GS_131 (not RVWUNIT), GS_137 (not RVWLUNIT), PRESET3 (not PRESET2), OBJT3 (not OBJT2); the losers
|
|
# have a spurious .data/.rdata mismatch and do NOT link byte-exact. GS_106 is an 8-instruction object
|
|
# whose .text pattern recurs in game code, so it anchors uniquely only within the libgs window
|
|
# (psyq_identify/psyq_integrate take the 0x80051804..0x80057928 range — see make extract).
|
|
# psyq_link_region --verify confirms the chosen 31 are per-object .text byte-identical.
