Case contract

Given has_match, tag_ok, modified, since, if unmodified since is ignored when if match present. Return the protocol decision or transformed value; fields are validated and fixtures state boundary outcomes.

Why this case matters

This deterministic http caching model isolates the if-unmodified-since-is-ignored-when-if-match-present policy at a network component boundary.

One recorded failure
