  ai:bob on 45.55.164.30
  ai:charlie on 159.89.187.128
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate

  consolidate HTTP 201, consolidated_id=558486bd-676a-4501-a268-66739e396e94
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
