-   * LWW: Subtask edit wins over parent delete when subtask is edited later
+   * LWW: Subtask deletion cascades with parent delete
    *
-   * This is a critical edge case for LWW conflict resolution. When a parent
-   * task is deleted on one client while the subtask is edited on another,
-   * if the subtask edit has a later timestamp, it should win. The subtask
-   * survives but becomes an orphan (references a deleted parentId).
+   * This tests that parent deletion properly cascades to subtasks even when
+   * the subtask is edited concurrently on another client with a later timestamp.
    *
-   * The lwwUpdateMetaReducer must handle this gracefully without crashing.
+   * Parent deletion cascades to all subtasks to maintain data consistency.
+   * Without this, orphaned subtasks with invalid parentIds would cause issues.
    *
    * Scenario:
    * 1. Client A creates parent task with subtask
    * 2. Both clients sync
-   * 3. Client A deletes the parent task (which deletes parent and subtask locally)
+   * 3. Client A deletes the parent task (cascades to subtask locally)
    * 4. Wait for timestamp gap
    * 5. Client B marks subtask as done (later timestamp, doesn't know parent is deleted)
    * 6. Client A syncs (uploads delete operations)
-   * 7. Client B syncs (LWW: B's subtask update has later timestamp)
-   * 8. Verify: Subtask survives with B's changes (orphaned but functional)
-   *
-   * NOTE: This test is skipped because the expected behavior (subtask surviving
-   * parent delete via LWW) is not yet implemented. Currently, when a parent is
-   * deleted, all its subtasks are also deleted regardless of later edits.
+   * 7. Client B syncs (delete cascades to subtask despite later edit)
+   * 8. Verify: Both parent and subtask are deleted on both clients
