Case contract

Bounded offline decision model: dns negative ttl is minimum of soa ttl and minimum field. Inputs are already validated protocol fields; the explicit fixtures define the supported policy, not a complete protocol implementation.

Why this case matters

This deterministic dns resolution model isolates the dns-negative-ttl-is-minimum-of-soa-ttl-and-minimum-field policy at a network component boundary.

One recorded failure
