        1. Start a 3-node cluster with 3 mnodes.
        2. Create a 1-replica, 1-vgroup database; create table, insert data, and verify.
        3. Stop dnode2 → insert data → start dnode2 → insert data.
        4. Stop dnode3 → insert data → start dnode3 → insert data.
        5. Stop dnode1 → insert data → start dnode1 → insert data.
        6. Verify data integrity across all nodes.
