  ai:bob on 159.203.143.39
  ai:charlie on 104.236.212.12
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate

  consolidate HTTP 201, consolidated_id=168da82e-a768-4d94-aed4-9663b1657392
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
