Report #17497

[architecture] Router agent dispatches a task to a specialized agent that lacks the context or capability to complete it, resulting in hallucinated outputs

Implement confidence-aware routing where the router evaluates its certainty before handing off, and specialized agents can explicitly reject tasks with a structured fallback to the router.

Journey Context:
Standard routing assumes the destination agent can handle the task. LLMs often accept tasks they can't do well, leading to silent failures or hallucinations. Allowing a 'reject' or 'low confidence' return path prevents blind alleys. The router can then retry a different agent, ask the user for clarification, or fall back to a generalist, preventing the system from painting itself into a corner.
