Case contract

Given answers, additional, allowed, dns additional records do not override authoritative answers. Return the protocol decision or transformed value; fields are validated and fixtures state boundary outcomes.

Why this case matters

This deterministic dns resolution model isolates the dns-additional-records-do-not-override-authoritative-answers policy at a network component boundary.

One recorded failure

Sample boundary fixture
