 * event is dropped from Sentry only when EVERY retained cause code is one of
 * these; the user has already been given the correct remedy (choose a writable
 * location and rerun), so the report is pure noise.
 *
 * This is a NEW, reporting-only constant. It is deliberately SEPARATE from the
 * error-attribution tables `LOCAL_FILESYSTEM_ERROR_CODES` (fetch-template) and
 * `DIRECTORY_ACCESS_ERROR_CODES` (dir-arg), which classify errors for the
 * user-facing message and are intentionally broader — they include `EINVAL`
 * and `ENOTDIR`, which can indicate a genuine product bug and must keep
 * reporting. Do not couple this set to those tables.
