Parent State ID: 10
State Depth: 4
Action Taken: paint-down(robot1, tile_2-2, tile_2-1, black)
Action Reasoning: The robot should paint the tile directly below it to begin achieving the goal for row 2, starting with tile_2-1 in the correct color (black), before moving to paint other tiles in row 2.
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 black, Tile_2-2: clear, Tile_2-3: clear, Robot1: on tile_2-1 holding color black, Color_white: available, Color_black: available
Action Path: ['down(robot1, tile_0-1, tile_1-1)', 'change-color(robot1, white, black)', 'down(robot1, tile_1-1, tile_2-1)', 'paint-down(robot1, tile_2-2, tile_2-1, black)']

INACTIVE REASON: deactivated because diagram generation failed or invalid action chosen: Tile_2-2 should be painted white, not black, violating the goal state's constraints.
