close=0 alone missed fns sig_unify regresses to close>0 post-transform (e.g. func_8014B944,
self-MATCH every wave, never banks). Also match the drafter's 'none — MATCH' where_stuck verdict.
Excluded set 7 -> 16; pool waves now draft more FRESH targets (wave-8 close-rate already up to 0.21).
- self-MATCH-but-gate-rejected fns can never bank via re-drafting (the drafter reproduces the
byte-correct body the gate rejects again) -> exclude from POOL selection so agents draft FRESH
targets; they stay in the backlog as recovery-tooling/hand-finish fuel
- CURRENT_PHASE: sustained-loop state + pool-mode override policy (compaction-recovery anchor)
- grinder.py: persistent blacklist for permuter-won/gate-rejected (plumbing-bound) fns;
stops the tried.clear()-after-idle churn (was 0 banks in 8h on func_8014F3E8/func_8014FE60)
- sig_unify.py rewrite_def: adopt the canonical param list on arity mismatch (DEF-side
loose-typing wall) — unused extras sit in $a0-$a3, free at -O2; banked func_8016EDEC/EE40
- cookbook §22 (DEF-side recovery + grinder blacklist); CURRENT_PHASE option-C log
- compounds: sig_unify is in the gate pipeline -> every future wave + the grinder auto-recover
- residual class travels with the draft: drafter stamps // @class / // @stuck; gate_stage logs
the worker's gcc-quirk class to the backlog (not the coarse manifest class).
- wave_targets.py --class <C> / --list-classes: class-grouped re-attempt waves over the backlog's
classified near-misses (REGALLOC/SCHEDULE/REMAT/STRUCT/IV/LOOPGUARD/LOOSE/PLUMBING).
- orchestrator prep: auto-picks a class-focused wave when a class accrues >= threshold near-misses,
else a fresh pool harvest; clears the draft dir per wave.
- tools/workflows/distill.js: post-wave agent extracts NEW byte-verified gcc idioms -> cookbook §21
(R16, conservative); drafters now read the LIVE cookbook so distilled idioms feed forward.
- runbook: the full prep->worker->gate->distill cycle (the Phase-18 close-rate loop, automated).
- gate_stage on the 15 worker drafts saved before the reboot: banked 2 byte-matches,
propagated x134 (dedup 1508->1510); the gate process was killed pre-commit (empty log),
banks recovered from the working tree (dedup_propagate fail-closed per-overlay = verified).
Remaining 13 -> backlog near-misses.
- tools/workflows/worker_wave.js: parallel toolkit-aware drafter agents (xHigh) per target,
each writes its best matching C to the drafts dir (gate run by the orchestrator after).
args parsed robustly (harness may serialize to a JSON string — §20 gotcha).
- tools/wave_targets.py: select a wave batch from the fuel manifest (pool/region/N, skips
backlog walls). tools/grinder.py: token-free permuter grinder — permute backlog near-misses
-> gate_stage -> bank; STOP/heartbeat, idles for new worker near-misses, supervisor-friendly.
- the %lo-folding indexed-global -O0 residual (§18, long "irreducible") is CRACKED: declare
the global as "extern Struct base[]" (sizeof == stride) and access "base[i].field" -> gcc
keeps sym a symbol_ref and folds %lo(sym+off) into the store, byte-matching. The failing
forms "*(T*)(&sym + i*stride)" materialize &sym as a value first, blocking the fold.
- func_8013B7AC byte-gated + banked (x1 — the -O0 cluster is overlay-local, R14 finding above);
the idiom is reusable fleet-wide for ANY indexed-global access (-O0 or -O2).
- cookbook §18 ("%lo-folding indexed global — CRACKED") + §20 placeholder closed.
- the other 9 -O0 stubs: idiom applies but need per-fn -O0 drafting (3 quick ones tried, failed
on -O0 codegen detail; 4 are large) -> backlog/autonomy fuel. clean rebuild d19c9580 (R22).
- byte-proven: 0 drafts declare an extern struct/union data conflict; the lone apparent
DATA-conflict (func_8016A8FC/D_800AE620) was a typedef-REDEFINITION (Blk20 inline vs
engine_types.h, same type) masking the def-sig loose-typing wall. Stripping the inline
typedef compiles but still byte-mismatches. data-cast = code for 0 cases -> not built.
- cookbook §20 DATA-conflict note corrected; fleet unchanged 58.82%.
- byte-proven: only 1/134 overlays shares ov_SC01_077's -O0 cluster bytes; the 6 matched
-O0 fns reference per-overlay data addresses (func_8013B568 -> D_80187270 in ov_SC01_077
but 0x80182B04 in ov_SC01_005), so they're overlay-LOCAL, not ×134-shareable. The
Phase-18/19 'reach-134' label conflated function-present with byte-identical (R14).
- the §18 split infra (rollout tool + Makefile %_o0.o pattern + PROVIDE .ld) was built and
byte-validated to compile/link a 2nd overlay; the whole-binary gate then exposed the
per-overlay-data wall -> reverted (the finding is the deliverable, P9).
- -O0 rollout = ×1 per-overlay-unique re-matching (~0.2-0.3%), NOT +0.6% free -> SKIP.
cookbook §18 corrected; fleet unchanged 58.82%, 136/136 byte-identical.
- tools/cast_call_sites.py: per draft, callee whose canonical TU sig != draft's
intended sig -> decl->canonical (kills in-TU conflicting types, keeps symbol in
scope) + call-site cast ((ret(*)(args))func_X)(args) (codegen-neutral: gcc folds
the cast of a known symbol -> direct jal). Pure --in/--out; whole-binary gate is
the arbiter (G3/P9). Pipeline: canon_resident_calls -> cast_call_sites ->
sig_unify -> harvest_verify --chunk 1
- recovered 6 of T6 batch-1's 33 gate-fails byte-identical (func_80153C44/8015CF58/
801711FC/80161BE0/801683D8/8015F948); 5 propagated x134 + 1 local; check-all 136/136
- R14 CORRECTION of cookbook §20's '~33' projection (byte-proven): the batch is NOT
mostly callee-conflicts — ~6 callee (cast-recovered), ~18 DEF-side loose-typing wall
(def's matchable sig conflicts with the unchangeable caller-canonical; caller-side
fix BLOCKED because INCLUDE_ASM declares no symbol -> a shared macro's internal
extern is load-bearing in the 133 stub overlays), + a small DATA tail. The def-side
needs re-drafting under the caller-canonical sig (future wave), not a text transform
- cookbook §20 RESOLUTION + SETUP tool inventory (R16/R21/R30); CURRENT_PHASE log (R28)
- fleet 58.63% -> 58.82%, dedup 1501 -> 1508, 0 NON_MATCHING (G4)
- Drew (2026-06-21): cookbook entries / byte-verified findings / distillations / doc corrections
must be written DURING the producing session (fresh sessions get only summaries, lose the detail).
Defer only mechanical/continuable work. Extends R16. Memory: capture-knowledge-before-fresh-session.
- byte-verified: the 33 wave drafts that match_one-MATCH but fail the whole-binary gate are the
loose-typing wall in the CALL GRAPH (a callee declared with conflicting types across overlay
sites -> draft extern hits in-TU 'conflicting types'); match_one over-predicts (standalone +
masks jal/hi/lo). All recovery levers fail (sig_unify/canon_draft_decls/fix_arity/no-proto/
strip-externs); the only fix is per-site fn-ptr casts (SS17a) = Phase-21 recovery tooling
- diagnostic lesson: a failed in-TU build leaves a STALE .o (trust the whole-binary SHA, not objdump)
