feat(phase-8): link libgte byte-identical (T11, value-first) — 53/58 objs / +120 fns
...
- NEW tools/gen_lib_subsegs.py: generate splat subseg lines + integrate stub list for a
multi-block library (section-size-correct block ends — bakes in the libc2/T6 boundary
gotcha so it can't recur). Reused for libspu/libsnd next.
- libgte = GTE math, 53 objects in 22 blocks across the old 800b region (game code
interleaved as 800b/800b_2..800b_7). Resegmented from the generator; integrate window
0x4787C..0x51804 so it sees exactly the 22 in-region blocks
- 5 libgs-gap libgte objects (MTX_05/07/11/REG03/REG11) DEFERRED — gsgap1/2/4/5 stay
stubs (gsgap2 != MTX_07 exactly, needs a sub-split); documented in worklist
- progress.py linked_subsegs() now resolves `$(VAR)` stub lists (LIBGTE_STUBS) — the long
multi-block lists are passed via a make var
- region byte-verified 58/58 (clean, no scattered .bss); rm'd src/800b.c (region starts
with a lib block) so splat regenerates the fragments; 22 src/libgteN.c + 6 game frags
- dual byte-gate PASS: 143dbb89 with and without the libgte objects
- LINKED 590 -> 710 (+120); REAL still 43; byte-identical 37.93%
- reordered remaining libs value-first (libspu/libsnd next; dense libcard/libapi last)

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): libgs block 6 linked byte-identical (16 objs / 26 SDK funcs) — session F
...
- resegment 800b -> [800b pre][libgs6][800b2 post]; psyq_integrate the 16 contiguous
block-6 libgs objects (GS_110/119/120/121/122/123/127/131/133/134/135/137, PRESET,
PRESET3, OBJT, OBJT3) at vram 0x80053AF8-0x80057928; make check BYTE-IDENTICAL
- fix the resegment-triggered spimdisasm boundary instability: declare GsMulCoord2/3
(real MATRIX.o funcs, verified via the PsyQ object, R15 Ghidra-mirror pending) +
carve the s8 data descriptor table [0x53198,data,53198] (D_80062998 was shadowed by
a mis-detected func_80062998); ld_interleave FRONT_DATA -> 53198.data.o
- psyq_integrate multi-library support: per-lib NOLOAD section namespacing (.nl_<tag>_*)
so the 2nd integration's NOLOAD isn't skipped (was discarding OBJT3 .rdata/.bss);
trial-link includes sibling *_externals.ld (kills the '31 UNRESOLVED' false alarm);
global NOLOAD re-sort by vram (kills 'dot moved backwards')
- tools/make_libgs_block6.sh: reproducible curated-dir regen (disambiguated 16 objects)
- gated on [ -d .run/obj40/libgs_block6 ]: fresh-clone stub fallback verified byte-identical
- cookbook s9.4 (multi-library integration gotchas); CURRENT_PHASE updated
- next: full libgs integration (other 5 blocks), then Task 6 close-out + Task 7 PhaseEnd

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
