  "description": "Structural check on an IDV/KYC capture's C2PA manifest: claim well-formedness, hard-binding hash assertion, and claim-signature reference (art-123 reuse), plus a digitalSourceType read off the c2pa.actions assertion that flags trainedAlgorithmicMedia so a downstream reader knows the capture was declared AI-generated rather than a live camera capture. Structural check only, no trust-list or chain-of-trust claim. Feeds the session receipt builder's capture-chain field (art-359).",
