Longest prefix route wins over first matching route.

Case contract

Bounded offline decision model: longest prefix route wins over first matching route. Inputs are already validated protocol fields; the explicit fixtures define the supported policy, not a complete protocol implementation.

Why this case matters

This deterministic network routing model isolates the longest-prefix-route-wins-over-first-matching-route policy at a network component boundary.

One recorded failure

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