Availability models / Resource calendars
Reliable availability, reservations and payment flows.
Reservation software needs a precise answer to what can be booked, by whom and for how long. We model capacity, time zones, holds and cancellations before adding a calendar interface. Conflicting requests and delayed payment callbacks are tested so the system can protect inventory rather than merely display it.

Availability must be enforced in the authoritative booking transaction. Interface checks help users but cannot replace concurrency control on the server.
