  "message": "Abort instead of unwinding out of an inconsistent BTreeMap::split_off\n\nAfter the first move_suffix in Root::split_off, the source and result\ntrees share values through two temporarily invalid structures. If a\nlater key comparison panics, unwinding leaves the map with a stale\nlength over a partially detached tree, and consuming iteration then\ndouble-frees the shared values, reachable from safe code.\n\nGuard the descent loop with a mem::DropGuard that aborts on unwind,\narmed before the first move_suffix and dismissed once the borders are\nfixed.\n",
