phase A: each agent writes 3 related memories
  ai:alice on 138.197.33.142
  ai:bob on 104.131.116.229
  ai:charlie on 143.198.12.140
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate
  source ids (count=9): ['2a2a3fe2-51c3-41fe-93b7-e5149e1e5917', '4a65eb5c-da6e-4b4d-a0a5-c2c7f16bbc4b', '0b4ab4a8-b172-48ee-8f36-ab427b81a987', '35f44b98-1fcd-43e1-914e-a94af13e336b', '68bccda8-5f12-487a-a637-70774122906a']...
  consolidate HTTP 201, consolidated_id=fa6d272c-84bd-42cf-82d7-e392358dfb05
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
