Parent State ID: 1
State Depth: 2
Action Taken: paint-down(robot1, tile_2-1, tile_1-1, white)
Action Reasoning: The robot is currently on tile_1-1 and holding the color white, which matches the target color for tile_2-1. The best action is to paint down, as this will progress us towards painting the next required tile in the goal state.
State Description: tile_0-1: clear, tile_0-2: clear, tile_0-3: clear, tile_1-1: clear, tile_1-2: clear, tile_1-3: clear, tile_2-1: painted white, tile_2-2: clear, tile_2-3: clear, robot1: on tile_1-1 holding color white, color_white: available, color_black: available
Action Path: ['down(robot1, tile_0-1, tile_1-1)', 'paint-down(robot1, tile_2-1, tile_1-1, white)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Tile tile_2-1 is painted the wrong color (white instead of black).
