Case contract

Bounded offline decision model: fast retransmit fires on threshold crossing once. 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 fast-retransmit-fires-on-threshold-crossing-once policy at a network component boundary.

One recorded failure

Sample boundary fixture

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