         a mass phpcbf reformat over freshly-built payroll code, the sniffs
         below are temporarily excluded so `composer phpcs` is green on the

         PSR2/PSR12/Zend core, Yoda-condition ban, deprecated/forbidden
         function bans, underscore-prefix bans, etc.) still fails on NEW

             conditionals/array literals in domain logic (NL payroll/tax
             field names run long, e.g. `$vrijeRuimteDeclared`); wrapping
             ~161 current lines is a cosmetic mass-edit, not a defect fix.

         `if (!interface_exists(...))` guard. PEAR's IncludingFile sniff
         wants conditional loads to use `include`/`include_once` instead of
         `require`/`require_once` — but `include` only warns (and keeps
         running) on a missing file where `require` fails fast. Since this
         guards the standalone PHPUnit suite's ability to exercise real
         guard logic, failing fast on a missing stub is the correct
