A slow status screen accumulates unbounded events. Cap its queue and require reset when it cannot keep up.

A disconnected screen says All systems normal because incident cards retain their last values. Add transport freshness.

Investigating replay failures currently logs full incident descriptions. Add an allowlisted recovery event schema.

The prototype subtracts all historical holds and displays negative seats. Project availability from current authoritative states.

A zero-seat request creates a hold and a fractional request breaks counts. Enforce bounded integer quantities.

Two clients see one available seat and both reserve it. Serialize capacity consumption at storage.

Knowing a hold ID lets another user cancel it. Enforce owner scope in the repository boundary.

Confirm and expiry cleanup race, creating reservations from expired holds. Add an atomic transition with one time rule.

Timeout retry creates two holds for one user's click. Bind the operation key to the normalized request.

Clients see seats disappear for a transaction that later rolls back. Publish committed availability through an outbox.
