Report #35630

[architecture] Two agents enter an infinite loop of delegation due to ambiguous routing logic

Implement a strict max\_iterations counter in the orchestrator. Additionally, enforce a DAG \(Directed Acyclic Graph\) topology for agent routing so cycles are structurally impossible, or require a state transition to progress.

Journey Context:
LLMs lack global awareness of the workflow graph. If both agents lack the tool or knowledge to resolve a task, they will bounce it back and forth. A DAG prevents backwards routing. If cycles are necessary \(e.g., for self-correction\), a hard iteration limit is the only escape hatch. Tradeoff: Max iterations might terminate a valid but complex reasoning process prematurely, so the limit must be tuned to the specific workflow.
