Attempt Number: 5
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To align with the goal state, I will incrementally place cars into their correct curb positions. car_0 should initially be moved to curb_1, which is currently empty, without repeating previous actions.

New State Description:
Curb_0: car_2 is parked and clear.  Curb_1: car_0 is now parked and clear.  Curb_2: car_1 is parked and clear.  Curb_3: car_3 is parked and not clear (no cars behind).

Action Chosen:
(move-car-to-curb car_0 car_3 curb_1)
