Link local destination requires interface scope · case 04

Link local destination requires interface scope.

Member previewVariant 4 · 3 implementations · 4 checks per implementation

Case contract

Bounded offline decision model: link local destination requires interface scope. 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 link-local-destination-requires-interface-scope policy at a network component boundary.

One recorded failure

Sample boundary fixture

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