 * a fallback value (null, [], empty result) after touching DB or data-dir
 * paths. It re-throws when the caught error is the guard violation, otherwise
 * does nothing so the existing benign-fallback path can proceed unchanged.
 *

 *   try {

 * the open collapses it into the same `null`/`[]`/`0` the absent case returns —
