Only the structure changes (use `cbo.isValid` to check the code against the table).\n\n- The mask is applied as far as the digits go, which is what an input being typed into needs.\n- `options.pad` (default `false`) first left-pads the value with zeros to 6 digits. A number is treated as the string of its digits, so it is padded only with `pad`.\n- A string is read for its digits: other characters are dropped and digits after the last one of the mask are ignored.\n- Returns an empty string when there is no digit at all, also with `pad`. `null` and `undefined` return an empty string too.\n- A number is read only when it is a safe non-negative integer. A negative, fractional, non-finite or unsafe number returns an empty string.\n- New in 2.5.0 (#615), so every masked classification code has its formatter.",

The function does not pick out its digits.\n- A number is read only when it is a safe non-negative integer. A negative, fractional, non-finite or unsafe number is invalid.\n- The table follows the current release of the MTE, the \"Estrutura CBO (CSV)\" files of 10/07/2026 with 2,725 occupations. 2.4.0 used the older gov.br CSV of 06/06/2025 (2,694 occupations).\n- A code the MTE retired is no longer valid. 225142, 322105, 322115, 322120, 322125 and 782820 were valid in 2.4.0 and are invalid now.
