Case contract

Bounded offline decision model: sack reports out of order blocks without changing cumulative ack. 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 sack-reports-out-of-order-blocks-without-changing-cumulative-ack policy at a network component boundary.
