Report #85087

[architecture] Agents bounce a task back and forth indefinitely because neither takes terminal ownership or the routing logic is cyclic

Implement a strict max-handoff limit and ensure the orchestrator tracks the handoff depth, forcing termination or escalation to a fallback agent.

Journey Context:
LLMs are bad at recognizing they are in a loop. Without a hard limit, a multi-agent system will burn tokens infinitely as Agent A delegates to Agent B, who delegates back to Agent A. The tradeoff is that a low max-handoff limit might prematurely cut off a legitimately complex, multi-step workflow. However, a hard ceiling is essential to prevent catastrophic cost overruns and infinite loops.
