Report #87438

[architecture] A weak subagent is asked to decide whether to escalate and always says yes

Route tasks by confidence thresholds computed from calibration data and task capability requirements, not by asking the same model to judge itself.

Journey Context:
The obvious routing design is 'ask the agent if it is confident,' but a model's stated confidence is poorly calibrated and easily influenced by wording. A better design separates the router from the worker: the router sees the task embedding, required capabilities, and historical accuracy per capability, then dispatches to the cheapest agent whose calibrated confidence exceeds the task's risk threshold. This mirrors mixture-of-experts routing and is the difference between a system that gracefully degrades and one that silently delegates critical work to a model that is guessing.
