Parent State ID: 6
State Depth: 3
Action Taken: (move-curb-to-car car1 curb_0 car0)
Action Reasoning: We need to move `car3`, currently at `curb_1`, to `curb_3` following the sequence of swaps, and one option to progress is to prepare the curbs so the `car3` reaches its designated position, starting by freeing `curb_0`.
