phase A: each agent writes 3 related memories
  ai:alice on 138.197.18.48
  ai:bob on 104.236.100.154
  ai:charlie on 104.131.96.201
settle 8s for quorum fanout
phase B: collect source ids on node-1, then trigger consolidate
  source ids (count=9): ['d259afc7-1897-4345-8c3f-c28de1a2e6aa', '11a436fd-0536-4e51-9803-adacb102f826', '9d5c7b0e-0e78-4322-8abf-c0a8a656c258', 'aad16c73-d03b-45bc-9b0f-e8ce8c2d2f53', 'b10502d0-4b8f-410a-a969-b0f83a02754c']...
  consolidate HTTP 201, consolidated_id=9533862b-6f3e-4488-a3c9-f7ac265e1e01
settle 10s for consolidation fanout
phase C: verifying consolidated_from_agents on node-4
