    • Bug Category:
      Correctness - Unrecoverable Corruption / Loss
    • Severity:
      Critical

      Description

      Slice queries in descending sort order can create oversized artificial range tombstones. At CL > ONE, read repair can propagate these tombstones to all replicas, wiping out vast data ranges that they mistakenly cover.
