Report #12270

[architecture] Router agent dispatching tasks to specialized agents with low confidence causing immediate failure

The router must output both the target agent and a confidence score. If confidence is below a threshold, route to a generalist or ask the user for clarification instead of guessing.

Journey Context:
Hard routing based on intent classification is brittle. If the router is unsure but forces a handoff, the specialist agent operates on bad premises, leading to tool-call failures or hallucinations. Wasting tokens on a specialist only to fail is worse than falling back to a generalist. Implementing a confidence threshold with a fallback mechanism makes the system gracefully degrade rather than catastrophically fail.
