Return open appointment slots for a given specialty in a date range. Filters by clinic_id and skips conflicts with existing appointments.

Create an appointment for a patient with a provider. Requires an idempotency_key; repeated calls with the same key return the original appointment instead of double-booking.

Persist a structured intake note (symptoms, severity, onset) for a patient and assign a triage level (routine / elevated / urgent).

Keyword search over the clinic's protocol library. Returns ranked snippets the model can cite when answering.

Mark an existing appointment as urgent and reassign it to the clinic's on-call provider.
