Attempt Number: 2
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since the robot is on tile_0-3 and needs to start painting from the last row (row 2), the best action is to move down to tile_1-3 to get closer to row 2. This aligns with the requirement to paint the row below.

New State Description:
Tile tile_0-3 is now clear. Robot1 is on tile_1-3, holding color white. Tile_0-1 and tile_0-2 remain clear. Tile_1-3 is occupied by the robot. Tiles in row 2 are clear. Colors white and black are available for switching.

Action Chosen:
down(robot1, tile_0-3, tile_1-3)
