The 17 drafts that read 0/17 against the poisoned tree were never 17 codegen
failures. Re-gated on a clean tree: 9 banked, then re-gated TOGETHER per binary
(a draft that passes alone can still collide with a sibling in the same TU —
which is exactly what `morph_lerp` and `struct V8` did) — 9 of 9 held.

Wave 4 final: 40 targets -> 35 agent-MATCH -> 27 BANKED (68%).
One stray comment in one draft had masked eight real matches.
Wave 4 (wf_05895a19-121, 75 agents, 7.9M tok): 40 targets -> 35 agent-MATCH,
0 refuted, 5 NEAR, 0 FAIL, 0 drafts lost. 18 banked so far on the whole-binary
gate across 9 binaries; the other 17 are re-gating on a clean tree (see below).
PRIOR-NOTES SEEDING HELD AT SCALE: 10 of 12 seeded targets confirmed (wave 3
was 7 of 9). func_8017C294 — the x16 family, the largest single item on the
board — is now NEAR at **2 ins** (18 -> 11 -> 2 across three seeded attempts).
THE 4th COMMENT-BLINDNESS DEFECT OF THE SESSION, and the first with blast
radius. A crack agent annotated a decl in its draft:
extern void func_801842DC(s32 a0); /* TU:4023 INCLUDE_ASM (no decl) */
`corpus._INCLUDE_ASM_CAND` only skips lines that BEGIN with a comment marker,
so it read `INCLUDE_ASM (` out of the trailing PROSE, found no quoted path, and
refused the whole binary's stub oracle — correctly, by its own R32 contract.
That then failed gate_stage for every LATER binary in the run, because they all
walk the corpus: 12 binaries banked, then 5 were blocked by one comment in a
13th. Fixed the same way as the other three today: decide candidacy on
cdecl._mask'ed text, PARSE FROM THE ORIGINAL (the mask blanks string content
and would erase the asm path). Verified on 4 binaries incl. main (2,002 stubs).
AND THE DAMAGE IT LEFT: gate_stage raised out of the CorpusError BEFORE its
revert, stranding failed drafts spliced in src/. The 17 solo re-gates that
followed all read 0/17 — they were building a POISONED TREE, not judging their
own drafts. Residue reverted here; the 17 re-gate clean next.
The pattern is now sharp enough to state: any scanner that greps C source for a
token must mask comments and strings FIRST — and agent-authored drafts make it
far likelier, because their prose mentions the exact tokens our tools hunt for.
Wave 3 (wf_2680d8ff-539, 74 agents, 8.08M tok): 39 targets -> 35 agent-MATCH,
0 refuted, 4 NEAR, 0 FAIL -> 27 BANKED on the whole-binary gate (69%).
THE HARDENED HARNESS HELD: 0 drafts missing on disk (wave 2 lost 21 of 26 to a
shared output dir). Per-agent dirs + "never touch anything outside your own
directory" + a verifier that re-runs sha1sum LAST.
PRIOR-NOTES SEEDING IS THE SESSION'S BEST LEVER: 7 of 9 seeded targets
converted, including all three wave-2 whole-binary-gate misses and both big
NEARs — func_80189540 (551 ins, was NEAR +2) and func_8017C3BC (407 ins, was
NEAR 17). func_8017C294 (the x16 family) went 18 -> 11 ins: narrowing, not a
wall.
func_80189540 also required the one host edit its agent byte-probed:
src/ov_SC04_018/ov_SC04_018_jr_80188E1C.c:3093
extern s32 func_80189540(s32 a0, s16 a1) -> (s16 a0, s16 a1)
That TU has no call site, so the edit is inert; the OTHER TUs' (s32,s16) decls
are deliberately left alone (real call sites, and an s16 prototype there would
force caller-side truncation and could de-match banked callers).
Its agent also recovered a better draft that already existed at
.run/backlog_drafts/func_80189540.c — a 551-ins MATCH that had been DE-matched
to 549 by "fixing" the definition's s16 first parameter to s32, the exact
inverse of that draft's own warning. Restoring s16 recovered the match.
The wave-2 draft declared `extern void func_8012CAE4(void *a0);` at block
scope while the host TU already declares it twice at file scope (K&R at :2790,
`s32 a0` at :2849), so the gate reported PLUMBING: conflicting types.
Dropping the decl is wrong — match_one compiles the draft STANDALONE and then
the symbol is undeclared (gcc-2.7.2 prints that with no `error:` prefix, so it
reads as CC1 FAIL). The fix is to AGREE with the TU's visible decl and cast the
ARGUMENT (`(s32)a0` — same bits in $a0, codegen unchanged).
MATCH (99 ins) standalone, then BANKED on the whole-binary gate.
