Report #42009

[architecture] Routing tasks to specialized agents without a fallback when the specialist fails, resulting in dead ends or infinite self-correction loops

Implement confidence-aware routing where the supervisor evaluates the worker's output confidence or execution status, routing to a fallback generalist or human-in-the-loop on failure.

Journey Context:
Agents frequently hallucinate capabilities or return broken outputs \(e.g., a 'SQL Expert' returning a query that fails execution\). If the router blindly accepts this, the system fails. Routing must be a feedback loop, not a one-way street. The supervisor must inspect the worker's result or catch exceptions and have a defined fallback path. The tradeoff is added latency for validation, but it prevents catastrophic silent failures.
