Half close keeps receive direction open.

Case contract

Bounded offline decision model: half close keeps receive direction open. Inputs are already validated protocol fields; the explicit fixtures define the supported policy, not a complete protocol implementation.

Why this case matters

This deterministic connection lifecycle model isolates the half-close-keeps-receive-direction-open policy at a network component boundary.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
