refactor(phase-9): T8b — remove transitional defaults across link pipeline (no-EXE-default end state)
Every binary-specific value is now a REQUIRED parameter — the phase's #1-risk
mitigation (no EXE default an overlay could silently inherit):
- psyq_link.py: removed module EXE/VRAM_BASE; recover_sym_addrs/unique_byte_vram
vram_base now positional-required; link_object vram_base keyword-required (*,...);
CLI --vram-base/--exe required
- psyq_identify.py: removed EXE/VRAM_BASE globals; --vram-base/--exe required
- psyq_link_region.py + psyq_link_lib.py: dropped 'VRAM_BASE' import + EXE; defaults
removed (placement/classify/build_region required); CLI required
- psyq_integrate.py: dropped VRAM_BASE import + EXE; integrate() vram_base/exe_path/
symbols_path keyword-required; CLI --vram-base/--exe/--symbols required
- PROOFS: psyq_link bare -> 'required: --vram-base, --exe' (loud); build with AND
without SDK -> 143dbb89; wrong base -> cae22f7e; curated dirs regenerate identical

refactor(phase-9): T3 — argparse --vram-base/--exe for psyq_identify.py
- migrate to argparse: elf_dir + optional [lo hi] window positionals + --vram-base
/--exe flags defaulting to the kept EXE globals (TRANSITIONAL, removed T8)
- caller subprocess argv updates deferred to T4 (link_region/link_lib) and T8
(make_snd/apicard/gen_lib_subsegs) — one touch per file; defaults keep them green
- negative control: narrow window 0x50000..0x60000 -> 0/25 located (window threaded);
default + explicit -> 18/25; clean build -> 143dbb89 BYTE-IDENTICAL

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)
