GET /slots/availability, POST /slots/{id}/hold, POST /holds/{id}/confirm
and DELETE /holds/{id} on Laravel 12 and MySQL 8.
- availability cached for 10s behind a single-flight lock with a stale
copy, invalidated after commit on confirm and cancel
- oversell prevented by a conditional decrement, verified by the number
of affected rows rather than a preceding select
- idempotency enforced by a unique index on holds.idempotency_key
- active holds counted with an expires_at filter, so no background
cleanup is required for correctness
- 27 feature tests against MySQL, service documentation, Postman collection
