Case contract

Given draining, active, expired, graceful drain completes when active stream count reaches zero. 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 graceful-drain-completes-when-active-stream-count-reaches-zero policy at a network component boundary.

One recorded failure
