Summary
Enforce the normative validity condition
issued_at <= now < expires_at. Previously the verifier checked only whetherexpires_atwas in the past, so a correctly signed manifest with a futureissued_atcould be accepted asVALID.Future-issued manifests now fail closed with a
validity.issued_atmismatch. The expiry boundary is also exclusive as specified.Tests
