- canonical-sig layer (session 4): tools/census_conflict_callees.py + derive_canonical_sigs.py
-> a 20-extern byte-neutral block atop ov_SC01_077.c (LOCAL, not engine_core.h); census
conflict callees 20->0, blocked targets 24->0; gate pipeline now draft -> sig_unify (MANDATORY)
-> harvest_verify --chunk 1; fleet 136/136 byte-identical (R22), 55.51% (no regression)
- FINDING (R14/P9): the conflict wall is 7%-reach not ~2x; the 4 reach-134 circular targets are
ALL gcc-quirk/regalloc/layout-bound (0 banked); the high-reach core IS the quirk tail; struct
types are byte-neutral for matching (the wall is gcc codegen, not knowledge)
- leverage analysis: fleet % is function-count-weighted (size adds no %); "unblock many" = the
layer (declaration, not matching); reach is the lever (already reach-sorted); 247 tractable
reach-134 stubs ~ +3-4% projected
- GO/NO-GO: NO-GO on brute waves at the current ceiling; GO on a compiler-quirk research phase
(read gcc-2.7.2 source + Xenogears + the §10/regalloc classes, R17) -> then resume the wave
- docs: cookbook §16 corrected + hand-matching-process.md §8 (the layer + the finding + handoff)
- worklog archived -> phase-ends/logs/Phase17.md (R19); bumps 1.15.0 -> 1.16.0
- docs/gen2-roadmap.md: approved Gen2 plan (phases 8-15; finish-EXE-first,
two-repo LATE public flip, substantial exit) + Backup & disaster-recovery policy
- back up irreplaceable / hard-to-re-source artifacts to the private remote (R20):
- track ghidra/ (the RE database; *.lock/tmp*.ps transients excluded)
- tools/psyq/ working libs/tools (minus the two >100MB raw source archives)
- tools/bin/*.tar.gz (old-gcc cc1 compiler sources; extracted binaries stay regenerable)
- tools/ghidra-ext/ (GhidrAssistMCP 2.8.0 + ghidra_psx_ldr 2026.06.04 installer zips)
- .claude/settings.json: SessionStart + SessionEnd hooks (auto-start / clean-save the
headless Ghidra MCP); moved out of the gitignored settings.local.json so they are backed up
- docs/SETUP.md: document the MCP server lifecycle + persistence model + session hooks (§2.8),
a tooling inventory, .run/ runtime scratch (§1a), and the backup posture (§ Backup) — R21
- .gitmodules: ignore=dirty on the 4 submodules (maspsx/asm-differ/m2c/decomp-permuter) —
silences the phantom "modified" state from generated pycache + cross-filesystem filemode;
gitlinks unchanged (still at the pinned commits)
- rules R20 (back up irreplaceable work + gathered tooling; loosens R8) and R21 (keep
SETUP.md current) recorded in memory; to be formalized at the next PhaseEnd
