Drew T 3788a89b3c feat(phase-7): libcd linked into byte-identical build (58 SDK funcs) — session D checkpoint 
The first real PsyQ library is sourced from real SDK objects in the byte-identical
build, replacing the libcd-region asm stubs. Tasks 2'.1/2'.2/2'.3 — the whole
PsyQ-library-into-build mechanism, proven on the simplest library (libcd).

- psyq_link.py: per-object byte-link engine — recovers externals from the EXE's
  resolved relocations (R_MIPS_26 / HI16+LO16); weakens psyq-obj-parser's
  mislabelled common-style .bss globals so a strong --defsym wins
- psyq_link_lib.py: whole-library verify — 18/18 libcd objects byte-identical
- psyq_link_region.py: region link via NOLOAD data placement (no carving) +
  weaken-all-.bss; gap-aware per-object placement
- psyq_integrate.py: build wiring — splat resegment swap + per-object .text at
  vram + NOLOAD data; external resolution (func_<addr> aliases, symbols.us.txt
  jump-table names, recovered St*/CD_* globals, all weakened .bss commons);
  idempotent; conditional on tools/psyq/ (fresh clone builds via stubs)
- split_src_region.py: H5-safe src/*.c split at vram boundaries (preserves
  matched C + NON_MATCHING blocks)
- splat.us.exe.yaml: 5-way text split [pre][libcd1][gap][libcd2][post]
- src/800.c trimmed to <0x80043088; src/{800b,gap,libcd1,libcd2}.c splat stubs
- Makefile: libcd integration in the $(OUT) recipe (conditional + idempotent)
- cookbook §9.1/9.2/9.3 (the reusable mechanism for libgs/Gen2); CURRENT_PHASE
  session-D log; ≥3-session green bar A/B/C/+D
- make clean && extract && build && check -> 143dbb89... BYTE-IDENTICAL

Drew T 8ffb7f0607 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

Drew T 379185a799 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)

Drew T 5f937bdda5 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

Drew T d55882b4b8 feat(phase-5): splat config + all-asm byte-identical build of SLUS_007.26 
- config/splat.us.exe.yaml: splat PSX config (platform psx, compiler PSYQ,
  subalign 2, gp_value 0x80074750, base_path .., main segment align 4); one
  asm text seg [0x800] + data seg [0x531DC], header via splat's header segtype
- Makefile: implement extract (splat split) / build (as -> ld(splat .ld +
  undefined_*_auto) -> objcopy) / check (SHA1 vs config/check.us.sha, auto-run)
  / expected (asm-differ baseline) / clean; check-env untouched
- config/check.us.sha: committed build-check hash (validation stage 2)
- config/symbols.us.txt: now hand-curated — 15 2D_* -> gfx2D_* (illegal leading
  digit broke as), +D_800629D4 label; header flags re-merge + Ghidra-mirror (G6)
- .gitignore: ignore regenerable splat outputs (asm/, include macros,
  undefined_*_auto.txt); refine the earlier commit-asm/ note
- docs: SETUP.md §4.5 binutils 2.42 = byte-clean (no 2.35 downgrade), §5.3 +
  ledger #8 RESOLVED -G0, §6.3 as-built; memory-map.md gp0 -> -G0 + text/data split
- MILESTONE: make extract && make build && make check -> build/us/SLUS_007.26
  SHA1 143dbb89... == original (BYTE-IDENTICAL), 100% asm, check fails on corruption
- rule R15 (symbol file = curated, valid-identifier build input, Ghidra-mirrored)
- bumps project version 1.4.0 -> 1.5.0

Drew T ffe2352db2 feat(phase-4): matching-build toolchain (WSL) — make check-env green 
- apt: build-essential, binutils-mipsel-linux-gnu 2.42 (+gcc-mipsel 12.x), ninja
  1.11.1, python3-pip/venv, libelf-dev, clang-format, p7zip, bchunk, bsdmainutils
- .venv + splat64 0.41.0 ([mips]: spimdisasm 1.41.0, rabbitizer 1.16.2, PyYAML 6.0.3)
- 4 pinned submodules under tools/: maspsx@874855c5, decomp-permuter@b44b0622,
  asm-differ@2ad4a4a4, m2c@4266cc28 (.gitmodules)
- old-gcc 0.17 cc1 candidates -> tools/bin/gcc-2.7.2-{psx,cdk}/ (32-bit i386 static;
  tarballs are flat + same-named -> per-subdir extraction); CHECKSUMS.sha256 committed
  (gitignore exception !/tools/bin/*.sha256); psx cc1 self-id "GNU C 2.7.2 [AL 1.1,
  MM 40] Sony Playstation"
- Makefile: check-env (.ONESHELL bash) asserts python>=3.12, venv import splat, both
  cc1 (stdin smoke), maspsx, mipsel as/ld/objcopy, sha1(EXE)==EXPECTED_EXE_SHA1;
  binutils>=2.38 -> WARN (verdict deferred to Phase 5, §4.5); extract/build/check/
  expected/clean are loud-failing Phase-5 stubs (names per §6.3)
- docs/SETUP.md: as-built versions; §4.7 corrected (i386, flat-tarball fix); §4.8
  deferred to Phase 6; ledger #5 confirmed (Ubuntu 24.04.4), #6 (2.42), #7 (sha256)
- MILESTONE: make check-env exits 0; zero ROM-derived bytes staged
- bumps project version 1.3.1 -> 1.4.0
