  "purpose": "Decodes AI/ML provenance assertions off a C2PA manifest's assertion array: ALL entries in every c2pa.actions/c2pa.actions.v2 assertion (a manifest can carry a created -> edited -> published history; this reads the whole chain, not just the first action, generalizing beyond art-361's single-action IDV-scoped read), the full IPTC digitalsourcetype NewsCodes vocabulary (raw code always surfaced, an unrecognized code is never silently dropped -- it lands in unrecognized_source_types), and c2pa.ai_training / c2pa.ai_generative_training training-and-data-mining opt-out assertions (training_mining_opt_out: true/false/not_asserted, read only from an explicit boolean, never inferred). Reports assertions only -- never adjudicates whether an assertion is true, and absence of an AI/ML assertion means nothing (not evidence of human authorship, not proof of AI generation). Reuses art-123's assertion-array input shape as a sibling stage; zero edits to art-123 or art-361. Zero network calls, zero PII.",
