/**
 * Scrap tool to fix domain transfer data corrupted in b/33289763.
 *
 * <p>A bug caused some domains to have their transfer data overwritten with SERVER_CANCELLED
 * resolved transfer data upon their deletion, regardless of the original transfer data. The
 * previous version of this tool fixed domains where their original transfer data was empty by just
 * removing the corrupted transfer data. However, one other domain was affected that did have
 * pre-existing transfer data; this domain was not fixed earlier, so this new version of the scrap
 * tool fixes it by restoring what the original server-approved transfer data.
