Every $filter->filter(…) invocation creates a new archive that contains only one file and the existing archive with the previous file gets overwritten. Solution:

$filter = new Compress([
  'adapter' => 'Zip',
  'options' => [
    'archive' => TEMP_UPLOAD_PATH . DIRECTORY_SEPARATOR . 'download'
      . DIRECTORY_SEPARATOR . $result['downloadResult']->r_download_id . '.zip'
  ]
]);

// assuming you _can_ create archive from the whole directory
$filter->filter(TEMP_UPLOAD_PATH . DIRECTORY_SEPARATOR . 'download'
  . DIRECTORY_SEPARATOR . $result['downloadResult']->r_download_id);
