Stage 18 CRITICAL: CRLF gold-coordinate defect - all maud scores wrong; fused flips to KEEP

↗ view on GitHub · Eli Ziff · 2026-07-31 · 49107804

Two independent adversarial audits converged on the same defect and a
first-hand minimal repro confirms it: the 17 maud corpus files are
CRLF, upstream gold spans are LF coordinates (334/334 match the
answer oracle under LF, 0/334 raw). Corrected: ctx maud ansR
0.1385->0.4985, fused 0.1449->0.6057, fused pool R@48 0.635->0.863.
Fused grounded confirm flips DROP->KEEP (+0.107 vs +0.02 bar); R4
invalidated; maud-bottleneck narrative was ~65% artifact. Companion
findings recorded: composer noise floor (paired 1-sigma 0.0065,
gates of 0.01-0.02 inside noise), holdout task-staleness (98-100%
template reuse; privacy_qa has NO holdout), bed easiness (doc named
in query, doc_hit ~100%), D2-D8 scorer defects. Standing corrections
adopted: coordinate-corrected scoring everywhere, C1 judged both
ways, fused reinstated as ceiling arm, Stage 19 protocol additions.
