The extension live-provenance.md registers wai.live.provenance: the per-segment C2PA Manifest Box method and the Verifiable Segment Info method, written as C2PA 2.4 §19 defines them for a CMAF track carried under draft-ietf-moq-cmsf-01, where a segment less its C2PA boxes is its MoQ group's objects, so the segment's hard binding and the group receipt's Merkle root commit to the same chunks. Session keys rotate in a segment's manifest and also sign the group receipts. wai-rs feature live_provenance writes and verifies it with no C2PA library: BMFF, JUMBF, COSE_Sign1 with EdDSA, the claim signer's X.509 chain, and the receipts through jwp_delivery. The corpus live-conformance/c2pa-live/ has five good streams and a negative for each of the thirty reasons. Co-Authored-By: Claude Opus 5.5 <[email protected]>
