phase A: each agent writes 3 related memories
  ai:alice on 157.245.213.165
  ai:bob on 104.131.170.128
  ai:charlie on 165.227.105.24
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate

  consolidate HTTP 201, consolidated_id=e29bb6e6-25ba-4413-bc7a-1645522817d6
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
