Step 1 lints a PostalAddress24 block for structure type (FULLY_STRUCTURED, HYBRID, UNSTRUCTURED) and silent-fail duplication. Step 2 validates BIS CPMI d218 party completeness (UETR UUIDv4, party names, BIC, LEI format, purpose code format). Step 3 validates originator and beneficiary LEIs via ISO 17442 mod-97 and scores Wolfsberg payment transparency. All three steps always run. ZERO PII BY CONSTRUCTION: addresses are structural fields only, LEIs are public GLEIF registry data.",
