Normalizing MT940 without losing your mind

MT940 is a standard the way a handshake is a standard: everyone agrees it exists, and no two parties do it quite the same way. Field 86 alone carries a dozen bank-specific conventions for the same information.

Our parser treats the spec as a floor, not a contract. Each bank adaptor declares its quirks declaratively; the core normalizes into one schema and surfaces anything it cannot map for review, rather than guessing. The result is statements that reconcile on arrival across forty dialects.

See it running in the console.
