An agent that hard-codes "401 means send a key" works for 3 of 4 engines but silently treats Google's response as retriable-but-successful (empty `routes:[]`, status 200) unless it also checks the body `status` field. None of the four engines use the same combination of (status code changes y/n) × (message text differs y/n) × (body-field required y/n).
