Two code +fixes en route (sign-wipe combo bug + configurable gate), both fire-certified. +end075 (beta 7.5e-4 from s345000): best 3.4805, val climbing to 3.9, gn doubled — LOWER beta +did WORSE than the original 3e-3 over the same segment. LR-scheduler suspect CLEARED (resume +fast-forward exists, line 813). Diagnosis: at s345000 the corridor is EMPTY — ceiling ~1e-3 +(contraction) while the state's elevated relax-noise floor (resK stuck 2.6e-4 at ALL beta, +100x above healthy) pushes the effective lower bound UP past it. Over-ceiling operation bakes +in state damage (the 72M simple-lineage lesson, width edition). +CLOSURE PROBE (resK-to-floor reading, rho-noise verdicts discounted): s250000 CLEAN at 3e-3 +(resK 1.3e-6, ceiling ~5e-3) | s300000 boundary (3e-3 resK 2.2e-5) | s345000 dead.

Verdict = best vs +3.3839 (bsign fixed-3e-3) and vs 72M band 3.364. + ### RESULT 59b (2026-07-24): C768 CEILING MEASURED — the run spent its second half 2-3x ABOVE the ceiling, and the ceiling sinks UNDER BSIGN at this width. R59's "graze" and "stability transfers" both CORRECTED. |
