Provenance Revision Lineage

by Revision Lineage Check in Security & trust

x402 APIPassing, checked 8 h ago

Check a revision handoff before reusing evidence. Compare one initial or superseding transition with its declared predecessor; return lineage inconsistencies and an integrity receipt. Does not establish authenticity, semantic equivalence or inherited review approval. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.
