[scenario-4 hermes] phase A: launching concurrent 30-row bursts from 3 agents
[scenario-4 hermes] all 3 bursts complete; settle 20s for W=2 fanout convergence
[scenario-4 hermes] phase B: querying node-4 aggregator for per-agent counts
[scenario-4 hermes]   ai:alice: count=30 (expected 30) wrong_agent_id=0
[scenario-4 hermes]   ai:bob: count=30 (expected 30) wrong_agent_id=0
[scenario-4 hermes]   ai:charlie: count=30 (expected 30) wrong_agent_id=0
