ROUTE a symptom to the provider behaviour that explains it. Use this when the user names a provider or a domain (payments, email, auth, SMS, subscriptions) and you need to know what that provider ACTUALLY does — not what its docs say, and not what can be inferred from reading the integration code. Reading the code tells you what your app does with a field. It cannot tell you what the field MEANS at the provider — whether a line item is a seat count, whether a 200 body carries ok:false, whether an event can arrive out of order. That is the class of bug this routes. Returns {spec, workflow, scenario, confidence, reasoning} plus `next_actions`: a typed list of what to call next, with arguments pre-filled. Follow it rather than improvising the next step.
