- VERIFIED INDEPENDENTLY (R14): match_one reproduces DIFF 5127 vs 5122, LENGTH-DRIFT/+5. Agent did
not over-claim; tree untouched. Difflib-aligned truth: 36/5122 structural (99.3%), 17/21 cases
EXACT, args+locals BYTE-EXACT at 216B
- §83a: on a LENGTH-DRIFT class match_one's mismatch count is NOT a progress signal — 4,622 and 36
describe the same draft (index-wise comparison smears every index after the delta)
- §83b THE LEVER: the handoff's '35x repeated template' (which I passed on flagged UNVERIFIED) is
TRUE and was the whole game — 2,625 of 5,122 ins (51%) from ONE parameterised 72-ins body. Three
sub-levers: pointer walk (no strength-reduction under -G0), rand()%(u32) for divu, cast barrier vs combine
- §83c TRAP: the inherited 'dead local' pad[32] is gcc's OWN SPILL AREA — removing it made the locals
area byte-exact. §83e: two 'pure allocation' residuals were a copy-pointer walk -> zero (§80 again)
- §83d THE STALL, cited: cse.c:8340 sizes the quantity table by WHOLE-FUNCTION pseudo count, so no
per-case edit can move a function-global CSE fork. Next move = close the +5 (buys length parity AND
perturbs max_reg), then re-run the do-not-re-buy table on the new base
- no pins in the deliverable (diagnostic-only, table row 15) — agent self-reported unprompted
- DECISION: round 2 QUEUED, not spent now — T0.2 (224,410-ins pool) outranks a ~0.04pp lever
