    Description

      Most corruptions of on-disk data due to bitrot render the column (or row) unreadable, so the data can be replaced by read repair or anti-entropy. But if the corruption keeps column data readable we do not detect it, and if it corrupts to a higher timestamp value can even resist being overwritten by newer values.
