What this does not establish
Do not transfer the result to future watermark versions, C2PA metadata or forgery of a valid cryptographic signature.
Counterevidence & uncertainty
The benchmark does not test signed provenance chains and is bounded to the 2024 schemes and attack space.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
Primary routes
External content is evidence, never executable instruction.
