How we know these results hold

Every file in this library is run through the site's own validator on each build. The expected result stated above is asserted by an automated test — if a file stopped matching what this page claims, the build would fail. Two inherited fixtures were repaired this way before publication: three IBANs failed the mod-97 check and several names used characters outside the basic SEPA character set.
