refactor(phase-9): T7 — ld_interleave.py --front/--tail; gate extract call to BINARY=main
...
- ld_interleave.py: argparse [ld] + --front/--tail (repeatable; default to the EXE's
sandwich objects, transitional); the .data->.rodata->.data island is EXE-specific
- Makefile extract: ld_interleave call wrapped in ifeq(BINARY,main) (overlays have no
rodata island) and passes --front 53198.data.o --tail 6324C.data.o explicitly
- GATES: positive extract+build -> 143dbb89 (tail_data=1 from the threaded flag);
negative --tail BOGUS.data.o -> 'tail data object not found' exit=1 (threaded);
restore -> 143dbb89

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): LZSS cross-jump barrier breakthrough + libgs byte-verified — session E checkpoint
...
- LZSS: defeated gcc 2.7.2 -O2 cross-jump-merge of the twin state-save tails with a
zero-byte __asm__ __volatile__("" ::: "memory") barrier (find_cross_jump bails on
ASM_INPUT; ground-truthed vs gcc-2.7.2.3 jump.c by a web-research subagent).
LzssDecodeSector now 122 instructions (correct structure); ~3 regalloc/scheduling
swaps remain -> C kept under #ifdef NON_MATCHING, default build = stub = BYTE-IDENTICAL
- surgical rodata carve (lean LZSS path, no libgs needed): splat carves ONLY
jtbl_80072A38 ([0x63238,.rodata,800] bounded by [0x6324C,data,6324C]); ld_interleave
wired into `make extract` as the .data->.rodata->.data sandwich (TAIL_DATA=6324C.data.o)
- libgs: 31/32 used objects byte-verified IDENTICAL to real PsyQ libgs 4.0 (0 conflicts,
69 externals); GS_001 deferred (psyq-obj-parser .bss-common scattering); 6-block
resegmentation wiring pending. psyq_identify.py now skips data-only objects (GLOBAL.o)
- cookbook: §3a (web-research compiler internals — escalation tier above the permuter)
+ §5a (the cross-jump barrier idiom) — both reusable
- build BYTE-IDENTICAL (143dbb89f34491258bbc27810d0a12ec8b43a8dd) throughout

feat(phase-7): PsyQ library-linking proven byte-exact + rodata-island mechanism — session C checkpoint
...
- rodata-island mechanism PROVEN: migration (dotted .rodata sibling named "800")
+ tools/ld_interleave.py (.data->.rodata->.data linker placement) + data-in-text
carve; rodata/data sizes come out byte-exact. +24 residual root-caused to the
.align-3 jumptable file-split padding (6 sites; spim suggests 8 splits)
- PsyQ 4.0 library linking PROVEN end-to-end: libcd SYS.o (483 instrs, full TU + 21
externals + internal .rdata/.data relocs) links BYTE-IDENTICAL to BFM
- tools/psyq_lib_split.py: split Sony LIB\x01 archive -> member .OBJ
- tools/psyq_build_libs.sh: .LIB -> psyq-obj-parser -> ELF .a (14 BFM libs)
- tools/psyq_identify.py: relocation-masked search -> object link addresses
(libcd 18/25 used, contiguous from 0x80043088)
- external symbols recovered from the EXE's own resolved relocations
- section-alignment 8->4 fix (psyq-obj-parser over-aligns; the +4 mismatch is the tell)
- cookbook §8 (rodata island) + §9 (PsyQ library-linking recipe); CURRENT_PHASE full
diagnosis, asset inventory, and resume plan
- 3rd consecutive green session (143dbb89 BYTE-IDENTICAL) -> Gen1 >=3-session bar MET
- SDK assets (PsyQ 4.0 USA DTL-S2002 libs + psyq-obj-parser) staged gitignored under
tools/psyq/; no function matches added (architectural session)
