Missing response validators cannot silently preserve a saved validator · case 05
Missing response validators cannot silently preserve a saved validator.
Case contract
Resumption accepts only an explicitly present incoming validator equal to the saved strong tag; absent or changed tags yield None.
Why this case matters
Range responses combine representation identity, conditional requests, framing, and partial-object state.
