description: "Parses a batch of synthetic TIP-20 transfers (with memos), runs OFAC/SDN hit screening, checks FATF Travel Rule field completeness (originator/beneficiary name + VASP ID, threshold US$3,000), scores AML typologies (structuring $9k–$9.99k, missing identity, unusual tx), and emits SAR determination + Travel Rule attestation. Bilateral: sending VASP emits; receiving VASP re-verifies. ISO 20022 pacs.008-subset artifact; instructed_amount = batch total."
