T36 CORRECTION (the important half). Building the cookbook sweep tool surfaced a defect in
tools/verify_map_findings.py, which I had already used to validate BOTH map audits:
- GNU C sources use FORM FEED (\f) page separators — loop.c 47, cse.c 36, reload1.c 27,
local-alloc.c 21. Python's splitlines() splits on \f; grep/sed do not. Every line number computed
after the first \f was shifted (up to 47 in loop.c), which is LARGER than the checker's own +/-40
window — precisely how a real quote gets reported FABRICATED.
- Re-run after the fix: T34 regalloc 27 OK/153 NEAR/0 FAB -> 180 OK/0/0. T35 four-file
47 OK/240 NEAR/12 FAB -> 299 OK/0/0. THE AGENTS' LINE NUMBERS WERE EXACT ALL ALONG. I had even
written the false "off by +2..+19" claim into the T35 agent prompt.
- MY DIAGNOSIS OF THE 12 WAS ALSO WRONG. I said agents pasted map prose into source_quote and
"verified" it by grepping — but I grepped claim_excerpt (which IS map prose) instead of
source_quote. The real source_quote was ` record_jump_equiv (insn, 0);` at cse.c:7511, a
correctly-located C line. Two stacked errors: a broken tool, then a check of the wrong field that
appeared to confirm it.
- Fixed: both tools use split("\n"); verify_map_findings.py documents the trap so it cannot return;
loop.md's "12 unverified" note is WITHDRAWN in place. Nothing was deleted on this basis (all 12
were CONFIRMED-status, none underpinned a refutation), and the T34/T35 upheld/overturned splits are
unaffected — those came from adversarial agents, not the checker.
T37 THE COOKBOOK SWEEP (what was asked for). New tools/sweep_citations.py puts the mechanical half of
a citation audit into zero-token tooling (offline-tooling-first): symbol-form cites are compared to
the real 2.7.2 definition line; file-form cites are localised to their enclosing function.
- matching-cookbook.md: 57 resolvable citations, all localisable. MIXED provenance but mostly sound —
materially better than the map files. loop.c:5556, local-alloc.c:1765/1795/1825, global.c:906/917/
924/1000, local-alloc.c:1021/1064, global.c:588/594, sched.c:820, expmed.c:556, jump.c:2131 all
land where the prose says. GENUINE MISS: expr.c:5535 is MIN/MAX optab code; the /s grant sites are
4577 and 4904.
- STATED LIMITATION: "lands in the right function" is weak for giants (expand_expr 4026->~6300,
jump_optimize 139->~2200). This is a CITATION sweep, not a claim audit — proportionate because the
cookbook's idioms are byte-proven and its cites are explanation. No idiom re-litigated.
Docs+tools only: no src/ or config/ touched; R22 not re-run and not claimed.
