 * A mid-stream socket/body error, a connection failure (HTTP status 0, no

 * the partial. A real HTTP status (4xx/5xx) or a missing/unreadable body is not.
 *
 * `DownloadCancelledError` is intentionally NOT excluded here: this is only
 * reached after the caller's consumer-cancel gate, so a cancellation at this
 * point is our per-attempt abort (resume interrupt), which must be retried.
