Report #87945

[architecture] Agents waiting on each other for inputs or delegating back and forth cause the workflow to hang indefinitely

Implement strict timeouts and a maximum depth limit on agent delegation. Ensure the agent topology is a Directed Acyclic Graph \(DAG\) by design, preventing mutual delegation loops.

Journey Context:
In a flexible multi-agent setup, Agent A might delegate to Agent B, but Agent B realizes it needs info from Agent A. Without a DAG constraint, this creates a deadlock. While dynamic routing is powerful, the agent topology must be acyclic. If a loop is logically required \(e.g., iterative refinement\), it must be managed by a stateful orchestrator with a strict max-iteration counter, not by mutual delegation between peers.
