phase A: each agent writes 3 related memories
  ai:alice on 161.35.186.161
  ai:bob on 104.236.203.248
  ai:charlie on 45.55.83.112
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate
  source ids (count=9): ['1b41783b-f18a-466b-923f-f6dc998391a2', '1efe529c-985d-4380-9a67-1b5df5fec51f', '973289f7-2ae2-4277-a422-80a622f0a7a1', '6137755e-6fad-42dd-871e-7a1423905c28', '96d66fde-da70-48af-87f9-c3e8c6a3ae9b']...
  consolidate HTTP 201, consolidated_id=3d59096a-042d-4096-94ad-52e414c2aa89
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
