Size: S (Small)

Problem / Outcome

Define and enforce seat status types and valid transitions.

Scope

In-Scope:

  • 10 status types: Available, Sold, Reserved, Technical, Official, Blocked, Maintenance, Quarantined, Allocated, Inactive
  • Valid transition rules between statuses
  • Color codes for visualization

Out-of-Scope:

  • Custom status types

Acceptance Criteria

  • AC1: Each status type has defined color code for visualization
  • AC2: Invalid transitions are blocked (e.g., Sold -> Available without refund)
  • AC3: All status changes require reason and are audit logged
