 - **Architecture:** events/availability/capacity are Datalog facts + rules;
   recurrence expands to occurrence facts within a window; a booking checks rules
-  then appends a `store` event (idempotent, capacity-safe). Notifications are flows

 - **Determinism:** recurrence expansion + availability must be reproducible for a
   fixed window + ruleset; capacity checks must be race-safe (no overbooking).
