        # DTOs initialise readonly properties (metadata, relationships) and the
        # Health response via a private trait method called from the constructor.
        # This is valid at runtime — readonly props may be written once from within
        # class scope — but PHPStan only recognises direct constructor assignment.

        # DTO constructors keep a `...$args` variadic as a deliberate safety net so
        # that undocumented or future Paystack response fields are absorbed instead
        # of throwing. It is intentionally unused.
        - '#Constructor of class .* has an unused parameter \$args\.#'
