phase A: each agent writes 3 related memories
  ai:alice on 104.236.27.55
  ai:bob on 159.203.112.25
  ai:charlie on 45.55.231.253
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate
  source ids (count=9): ['b7a418cf-cfad-4994-8cb7-520aed6f1398', '19831d53-70de-4dd2-ab5d-2fc5debaaf0e', '9afbb8ba-f09a-466f-8c96-52c9c5f4ec53', 'b149ced1-386a-4e02-abae-59cea114bf50', '49048a68-4137-4225-a454-8fd3a4572e9a']...
  consolidate HTTP 201, consolidated_id=0c0e11c4-fa52-468c-8000-ce124dfad165
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
  consolidated_from_agents=['ai:charlie', 'ai:bob', 'ai:alice']
