Report #3401

[architecture] Two agents wait on each other's output and the workflow deadlocks.

Model coordination as a directed graph with explicit edges and an orchestrator that owns turn-taking; never let agents block on peer responses without a timeout.

Journey Context:
Peer-to-peer request/response between agents creates circular waits and unclear responsibility. Graph-based orchestration makes the next agent an explicit function of state, not a negotiated agreement. If you need conversation, use a supervisor that selects the next speaker. Timeouts and a fallback agent turn deadlocks into recoverable failures. This is why production systems prefer orchestrated graphs over autonomous chatrooms.
