[architecture] Router agent sending complex tasks to a weak specialized agent that confidently hallucinates

Implement a confidence threshold in the router. If the routing agent's confidence score is below the threshold, fall back to a generalist agent or ask the user for clarification.

Journey Context:
A common failure mode is an over-eager router dispatching to a specialized agent based on keyword matching, but the specialized agent lacks the full context to solve the problem. The specialized agent then confidently hallucinates an answer. By forcing the router to emit a confidence score \(via structured output\) and routing low-confidence tasks to a generalist or back to the user, you prevent cascading failures and hallucination propagation.
