Parent State ID: 11
State Depth: 4
Action Taken: paint-down(robot1, tile_2-2, tile_1-2, black)
Action Reasoning: The robot is currently on tile_1-2, holding black, and needs to paint tile_2-2 (directly below) white. First, it must move to tile_2-2, as the goal is to finish the second row with the correct colors, starting with black.
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 black, tile_1-3: clear, tile_2-1: clear, tile_2-2: painted black, tile_2-3: clear, robot1: on tile_1-2 holding color black, color_white: available, color_black: available)
Action Path: ['down(robot1, tile_0-1, tile_1-1)', 'change-color(robot1, white, black)', 'right(robot1, tile_1-1, tile_1-2)', 'paint-down(robot1, tile_2-2, tile_1-2, black)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Tile_2-2 is painted black instead of white, violating the goal state's color requirement.
