Case contract

Given records, elapsed, dns ttl is reduced by resident seconds and clamped. 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-ttl-is-reduced-by-resident-seconds-and-clamped policy at a network component boundary.

One recorded failure

Sample boundary fixture
