feat(phase-24): T3 — permuter setup fixes (pins/GTE-asm, typedefs, -O0); flagship closed

- p16_permute.hide_asm: b64literal-pragma carrier for register pins + GTE __asm__ blocks.
  pycparser parses the pragma; decomp-permuter's process_pragmas decodes it back so cc1 sees
  the real pins/asm (regalloc steered, mvmva compiles). No submodule edit (reuses its own carrier).
- drop_preproc_and_scalar_typedefs: keep #define + custom struct/typedefs, drop only #include
  (fixes func_801412A8 'OTLINK undeclared'); +f32 typedef gap; make_base_c hides asm.
- compile.sh/compile_o0.sh: prepend .include "macro.inc" so GTE mvmva assembles (the real build
  gets it via include_asm.h, which base.c omits + -DPERMUTER disables). Byte-neutral for non-GTE.
  compile_o0.sh (-O0) auto-selected for _o0 targets.
- run_masked.py: expr_type->int fallback for hidden-pin vars -> 0 internal-permuter-failures
  (perm_split_assignment/perm_temp_for_expr no longer KeyError on pinned drafts).
- ALL 5 seeds parse+compile (base 4/110/36/52/77). FLAGSHIP func_80132784 (4/400) CLOSED to a
  masked-0 that match_one confirms MATCH (400 ins) -> .run/wave/func_80132784.win.c for T4 gate.

feat(phase-24): T2 — floor-free relocation-masked permuter scorer (-drz)

- tools/masked_diff.py: shared objdump -drz masking oracle (jal/j 26-bit + HI16/LO16
  immediate mask; -z keeps nop runs -> no GTE under-count). object-vs-object (permuter,
  +reloc-operand equality) and object-vs-.s (match_one) modes.
- match_one.py refactored onto masked_diff (-dr -> -drz); regression-clean on count-exact
  seeds (35/52/72/110, leaf-MATCHes), output format unchanged (gate_stage/grinder compatible)
- tools/masked_scorer.py MaskedScorer: drop-in for decomp-permuter's Scorer; scores masked
  .text closeness (bottoms out at 0) not the stock mnemonic-diff floor
- tools/permuter/run_masked.py: rebinds src.main.Scorer -> MaskedScorer (NO submodule edit,
  R3/R20); p16_permute.run_permuter wired to it
- VALIDATED: masked_self=0; masked_cand~match_one; STOCK floor 1750-2100 vs masked 36-77
  (the wander cause); live permuter base score = masked 77 (not stock 1930), descends to 74
- R14 SELF-CORRECTION: -drz confirms func_80132784 is 4/400 count-exact (T1's -dr 204 was a
  16-nop-collapse artifact); backlog re-logged close 4. The flagship IS 4 ins away.
- no build-input changed (136/136 untouched); 2 compile FAILs surfaced -> T3 (GTE asm, typedefs)

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
