phase A: each agent writes 3 related memories
  ai:alice on 104.236.6.125
  ai:bob on 167.71.177.137
  ai:charlie on 167.99.59.68
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate
  source ids (count=9): ['2136d449-97c7-452c-8fb9-1e217d8befa2', '94f25cf9-d7a1-438a-bd41-58233b2cf8e1', '9d24c031-e1d0-4363-99e0-c8a3c37c6df0', '8f186771-bb08-44a2-ab3b-c092b14e8bde', '580679e7-50e0-414d-8463-5275eed45fdb']...
  consolidate HTTP 201, consolidated_id=e1b88027-2cde-460e-a172-e318ed086599
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
