Report #2650

[architecture] Multi-agent system deadlocks waiting for responses that never come

Set end-to-end timeouts, idempotency keys, and failure policies per handoff; default to fail-fast with a retry budget rather than blocking forever.

Journey Context:
Agents calling agents can form long chains. If one link hangs, the whole graph stops. Without timeouts you cannot distinguish slow from dead. Without idempotency, retries create duplicate side effects. Each handoff should declare its SLA and a failure policy: retry N times, then escalate. This is standard distributed-systems practice applied to agent graphs.
