- BUG: the guard `not ln.rstrip().endswith(";")` misses m2c's declaration form
`M2C_UNK func_80178D40(s32, s32); /* extern */` — the raw line ends in `*/`, not `;`, so a
DECLARATION was accepted as a DEFINITION and the forward brace-scan swallowed the NEXT
function's body, handing remap_hseq a garbage unit.
- BLAST RADIUS (measured): 15 of 35 substantial-family exemplars were phantom "matches" — all
still INCLUDE_ASM stubs (incl. func_80178D40 and the carried-queue func_801670E4); 3 more
anchored on the Phase-17 canonical-sig layer's `extern … /* match-first, arity N */` decls and
templated garbage, leaving those families SILENTLY UNBANKABLE. The whole-binary byte-gate
rejected every one — no wrong match was ever banked (G3/P9 held) — but the engine burned a
build per sibling and every extract_unit-based readiness analysis was wrong.
- FIX: strip trailing comments before the `;` test.
- REGRESSION-GATED over the whole corpus (6,286 family exemplars, .run/_eu_before.json):
15 phantom exemplars now correctly refused; 3 garbage units corrected to the REAL definition
(found in the right region file); 0 real definitions lost; 0 unit contents otherwise changed.
src/ and config/ untouched, so the committed build is unaffected.
- cookbook §40: the trap + the general lesson — this is the phase's FOURTH silent-skip bug
(find_site braces, overlay_files splits, reconcile_decls fn-ptr regex, now this). A tool that
silently no-ops on input it cannot parse is indistinguishable from one that had nothing to do.
