Report #49794

[architecture] Infinite loops where agents pass tasks back and forth or evaluator keeps rejecting

Enforce a strict max\_iterations counter on loops \(generator-evaluator or agent handoffs\) and a circuit breaker. If the limit is hit, escalate to a human or fallback logic rather than retrying infinitely.

Journey Context:
LLMs are stateless and can get stuck in repetitive failure modes. If an evaluator says 'missing X' and the generator keeps failing to provide X, they loop forever. A hard limit with an escape hatch prevents runaway API costs. Tradeoff: Might abort a task that would have succeeded on iteration 6, but 5 is a reasonable heuristic for most LLM loops.
