Report #1359

[architecture] Agents waiting on each other's output in a circular dependency causes the system to hang indefinitely

Implement timeouts and circuit breakers at the orchestrator level. Never allow agents to block synchronously on another agent's response in a peer-to-peer manner; use an orchestrator-based topology where the supervisor handles timeouts.

Journey Context:
In a fully peer-to-peer multi-agent network, Agent A calls Agent B, which calls Agent C, which calls Agent A. Deadlocks are notoriously hard to debug in LLM systems because the API call just hangs. Moving to an orchestrator \(supervisor\) topology where agents are stateless workers that return control to the supervisor immediately solves this. The supervisor can enforce global timeouts and prevent circular dispatch. The tradeoff is that the supervisor becomes a bottleneck, but it guarantees topological acyclicity.
