Parent State ID: 34
State Depth: 6
Action Taken: paint-down(robot1, tile_2-2, tile_1-2, white)
Action Reasoning: The robot is on tile_1-2 and holding the color white, which matches the goal color for tile_2-2. The best action is to paint tile_2-2 white, moving us closer to the goal state.
State Description: (tile_0-1: clear, tile_0-2: clear, tile_0-3: clear, tile_1-1: clear, tile_1-2: occupied by robot1 holding color white, tile_1-3: clear, tile_2-1: painted black, tile_2-2: painted white, tile_2-3: clear, robot1: on tile_1-2 holding color white, color_white: available, color_black: available)
Action Path: ['down(robot1, tile_0-1, tile_1-1)', 'change-color(robot1, white, black)', 'paint-down(robot1, tile_2-1, tile_1-1, black)', 'right(robot1, tile_1-1, tile_1-2)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_2-2, tile_1-2, white)']

INACTIVE REASON: action path invalid: The last action is invalid because the precondition that `tile_2-2` must be clear is not met; it is already painted white. The current state's description and visualization are accurate, but the action violates the domain constraints.
