PDOStatement::setFetchMode() discarded active FETCH_INTO or FETCH_CLASS state before validating its replacement. Validate the candidate in local storage, then replace the tagged-union payload and release the old state after a coherent commit. This preserves state on validation failure and makes autoload or destructor re-entry safe.
