phase A: each agent writes 3 related memories
  ai:alice on 142.93.181.41
  ai:bob on 134.209.172.71
  ai:charlie on 142.93.79.13
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate
  source ids (count=9): ['8b74f771-1726-4ef9-bb06-41761550f9e4', 'ff368533-065a-40fa-86db-1d33dd2ac544', '5dac665f-5243-4c57-bada-a1b9bec93561', 'b7450b32-88ca-4fa0-b9c8-1bb6a28b82de', '911943c0-b296-49b9-ac8b-f0c53698011f']...
  consolidate HTTP 201, consolidated_id=2fbd2c26-c98d-4a88-b3b6-698303f4ada7
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
