Case contract

Bounded offline decision model: send buffer removes only cumulatively acknowledged segments. Inputs are already validated protocol fields; the explicit fixtures define the supported policy, not a complete protocol implementation.

Why this case matters

This deterministic transport flow control model isolates the send-buffer-removes-only-cumulatively-acknowledged-segments policy at a network component boundary.

One recorded failure
