Parent State ID: 10
State Depth: 4
Action Taken: paint-down(robot1, tile_2-1, tile_2-1, black)
Action Reasoning: The robot is on tile_2-1 holding black and should paint this tile. This action aligns with the goal state's requirement for tile_2-1 to be black. The long-term plan is to paint row 2 first before moving up to row 1.
