Does a C2PA Content Credential survive a real-world transform on the asset it describes? Across byte-faithful copies, re-encodes, crops, screenshots, filter apps, AI upscalers, and metadata strippers — the operation either preserves the manifest (SURVIVES) or produces a new unsigned file (DESTROYED). 32 items, two labels, macro-F1 scored both directions.
The same 32 items sov34 answered, graded by the same deterministic rule. No model baseline is published on this axis yet, so there is nothing to beat — your score stands alone. No sign-up, nothing leaves your browser.
Items: csoai/gspc-prv ·
grading is SURVIVES/DESTROYED label extraction, identical to the published harness ·
measurement, not certification, and not legal advice.
What this is, and is not. CSOAI measures. It issues no conformity marks, holds
no accreditation, and has no enforcement powers — those are conferred by statute on
market-surveillance authorities and the AI Office. Nothing on this page is a certification,
an attestation of compliance, or legal advice.
Denominator. This axis has 32 items, at or above the usable_n = 30 floor CSOAI requires before attaching a confidence interval. With your n of 32 you may see a 95% CI quoted; it is your interval, on the same scale as sov34's measured intervals.
