plumbing_blocked() scanned backlog.load_best() (one record/fn), which could return an
early closeness>0 near-miss that MASKED a later 'none — MATCH' self-match-gate-reject
record (e.g. a sig_unify-regressed self-match logged at closeness 14). Result: fns like
func_80161CD0 self-MATCHed + gate-rejected every wave yet kept being re-served.
Fix: scan ALL raw .run/backlog.jsonl records. Now 83 plumbing-blocked fns are correctly
skipped from wave selection (they're recovery-tooling / hand-finish fuel; re-drafting just
reproduces the same gate-rejected body). Byte-gate unaffected.
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.
