The blacklist recorded "permuter won, byte-gate rejected => plumbing-bound, never
re-permute" for 22 fns. It was manufactured by a gate that no longer exists.
- R14 ON THE PREMISE, TWICE (before touching anything):
* The roadmap's two named grinder bugs are ALREADY FIXED (commit:0327, commit:0200) — stale line.
* docs/tooling-audit.md:933-937 DOWNGRADED ITS OWN FINDING with three corrections: the
prescribed fix is a NO-OP (deleting the scanner banks zero fns — harvest_verify was
single-TU BY CONSTRUCTION, the defect was mislocalized to it); nothing is being discarded
now (grinder STOPPED since 2026-07-02 — confirmed via .run/auto/STOP); queue magnitude
inflated (1252, not 1298). T2's only real content was the persisted artifact.
- AND THE AUDIT'S SNAPSHOT IS ITSELF STALE (verified in code): harvest_verify is now fully
multi-TU — _stubs derives every stub across every TU from the corpus oracle (:122), render()
splices "each draft into the TU that actually holds its stub", _write() writes multiple
paths, un-stubbed drafts are REPORTED not silently dropped (R32). The gate that manufactured
the blacklist is gone. No harvest_verify change was needed or made.
- THE PROOF IT WAS MANUFACTURED, NOT OBSERVED: of the 22 entries, 8 have since MATCHED anyway
(func_80131D68/80149374/8014FE60/80150528/8016BBE0/80171C64/80174684/8017F290); the other 14
are still stubs and would have been skipped FOREVER on a dead gate's verdict. (16 of 22 were
split-hosted, so harvest_verify never compiled them — the permuter's byte-matches were
discarded UNBUILT. The audit predicted 5 matched-anyway; it is 8.)
- DONE: blacklist -> [] (poisoned copy preserved at grinder_blacklist.json.poisoned-pre-T2);
grinder.py now carries the RULE (R35): a blacklist entry is a verdict from a SPECIFIC GATE
and EXPIRES when that gate changes — purge and re-derive from the fixed gate, never inherit.
A persisted negative verdict is only as good as the instrument that produced it.
- No byte claim (analysis tooling + a scratch artifact only) -> no R22 cycle owed.
The grinder/backlog pipeline was ov_SC01_077-hardcoded 5 layers deep (same class as the
T7 lora_grind bug). Fixed all so the permuter grinder can process a non-077 near-miss:
1. gate_stage.append_record stores the source "binary"
2. backlog.FIELDS keeps it (else append_record dropped it)
3. backlog.load_best/_open_stubs is fleet-aware: a fn matched in ov_SC01_077 but
propagation-stuck stays OPEN in its overlay, so it surfaces via that record instead
of being dropped as "matched" (the grinder must SEE it to grind it)
4. p16_permute.setup takes the target binary's asm-subdir (was hardcoded 077)
5. grinder resolves per-binary asm + gates grouped by binary + allows unknown nins
Backward-compatible: legacy records (no binary) default ov_SC01_077.
Validated end-to-end: the 3 fresh reach-134 close=1 ov_SC01_000 fns now surface, resolve
to ov_SC01_000's asm, and gate via ov_SC01_000.
TWO byte-evidenced findings (redirect the fuel strategy):
- the reach>=2 close=1 fuel is MODEL semantic-misses, not permuter fuel: func_8012E27C's
target is "return 1" but the 7B drafted an empty "void f(void){}" (corpus overfit
empty-leaf); func_8012BF4C/AD64 are trivial sw/sh setters drafted empty. A corrected
draft banks them (+3 byte-identical via the fixed gate, @commit:0326); the permuter cannot
add a missing return/store. Lever = corpus-v3 leaf variety, not the permuter.
- x reach is propagation-capped: the 3 are inline-matched in ov_SC01_077_a.c (the stuck-
local cap) -> dedup_propagate "nothing to propagate" -> banked x1. Lever = dedup-collapse.
check-all 136/136 throughout. docs/gen2-mips-matching-model.md + CURRENT_PHASE updated.
- 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
- 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.
