harvest_verify.classify_fail kept only stderr lines containing the word `error`. gcc-2.7.2 emits
no `error:` prefix on hard errors, so lines like
src/…/ov_SC02_037_jr_8013B83C.c:447: multiple storage classes in declaration of `tail_…'
src/…/ov_SC06_025_jr_8012ACE0.c:2217: `tbl_D_80187044' undeclared (first use this function)
never survived the filter, `errs` held nothing but make's `Error 33` wrapper, and every hard error
was labelled CC1-FAIL(no-diagnostic) — "the compiler failed and we cannot see why". Measured cost
this session: 132 siblings of func_80132018 classified that way by one missing declaration, which
reads as a codegen wall and gets a family deprioritised. rtu_match had the same blindness repaired
at T0(b); the fix was never propagated here.
Fix: a diagnostic is a POSITION, not a vocabulary — `<file>:<line>: <text>`, plus the assembler's
`{standard input}:<line>:` (_SRC_DIAG). Context lines carry no `:<line>:` and are skipped.
Five controls pass, including the two that guard against over-fixing: PLUMBING still wins on a
declaration conflict, and a warnings-only failure still returns no-diagnostic.
Re-swept: 0 no-diagnostic remain. The 93 resolve to 35 redefinition-note, 11 D_801202A0
undeclared, 10 too-many-arguments, 4 too-few-arguments, 4 func_8001534C undeclared — every one a
cheap declaration/arity class, not a wall.
Residue now fully named (737): 207 undefined-reference across 42 symbols (a link-stage REMAP gap,
now the largest class), 138 DIFF (real divergence, 19% — the honest floor), 44 data-symbol
conflicting-types, 35 redefinition-note, 26 memcpy, 24 redeclared, 15 undeclared, 14 arity.
