Report #92384

[architecture] Agents delegating tasks back and forth in an infinite loop

Enforce a strict Directed Acyclic Graph \(DAG\) for delegation permissions and implement a hard maximum recursion depth for agent handoffs.

Journey Context:
LLMs lack global awareness of the call stack. If Agent A thinks Agent B should handle it, and Agent B thinks Agent A should, they loop infinitely, burning tokens. Allowing any agent to call any agent creates cyclic graphs. The fix is to model delegation as a DAG \(e.g., Router -> Coder -> Reviewer\) so cycles are structurally impossible, and to enforce a hard max\_depth limit in the orchestrator as a failsafe against prompt-induced loops.
