Re-gated all 958 closeness-0 open-stub backlog drafts through the FIXED gate
across 135 binaries in parallel: banked=0, near=957, failed=71. The closeness-0
backlog is genuine whole-binary near-misses, NOT tooling misses -- match_one's
isolated closeness==0 systematically overstates whole-binary bankability, and the
repaired gate recovers none. P9: a re-confirmed wall is as valuable as a dissolved
one. (The audit's tooling-walls were already banked by A3f/g/h + A9b, +2.1% instr.)
backlog.py: env-gated BACKLOG_NO_RENDER so parallel workers skip the render race
(append is atomic) -- backward-compatible parallel-safety. backlog.md refreshed
with the re-test's whole-binary-informed scores.
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.
