Fedwire Structured Address Linter

Lints a Fedwire or CHIPS ISO 20022 PostalAddress24 block against the November 2026 structured address mandate. On 2026-11-16 the Fedwire Funds Service and CHIPS remove the fully-unstructured postal address option in favor of a single hybrid format (Town Name and Country always required). Detects unstructured AdrLine-only addresses (banned), silent-fail duplication (AdrLine echoing structured field values -- causes STP rejection without a visible error code), and classifies structure type. For the SWIFT CBPR+ cross-border equivalent see lint_cbpr_structured_address (art-241).

Network
Fedwire and CHIPS structured-address rules are byte-identical for this lint (CHIPS aligns to Fedwire's hybrid format and the same 2026-11-16 date) -- one kernel, network only changes the citation in the output.
