Case contract

Given was_closed, now_closed, leased, connection close notification is emitted once. Return the protocol decision or transformed value; fields are validated and fixtures state boundary outcomes.

Why this case matters

This deterministic connection lifecycle model isolates the connection-close-notification-is-emitted-once policy at a network component boundary.

One recorded failure
