Parent State ID: 156
State Depth: 14
Action Taken: paint-down(robot1, tile_1-2, tile_0-1, black)
Action Reasoning: Since robot1 is holding black, it should paint tile_1-2, which is directly below and needs to be painted black.
State Description: Tile tile_0-1 is clear. Tile tile_0-2 is clear. Tile tile_0-3 is clear. Tile tile_1-1 is painted white. Tile tile_1-2 is painted black. Tile tile_1-3 is clear. Tile tile_2-1 is painted black. Tile tile_2-2 is painted white. Tile tile_2-3 is painted black. Robot1 is on tile_0-1, holding color black. Colors white and black are available for switching.
Action Path: ['right(robot1, tile_0-1, tile_0-2)', 'down(robot1, tile_0-2, tile_1-2)', 'paint-down(robot1, tile_2-2, tile_1-2, white)', 'change-color(robot1, white, black)', 'paint-down(robot1, tile_2-3, tile_1-2, black)', 'right(robot1, tile_1-2, tile_1-3)', 'left(robot1, tile_1-3, tile_1-2)', 'left(robot1, tile_1-2, tile_1-1)', 'paint-down(robot1, tile_2-1, tile_1-1, black)', 'up(robot1, tile_1-1, tile_0-1)', 'change-color(robot1, black, white)', 'paint-down(robot1, tile_1-1, tile_0-1, white)', 'change-color(robot1, white, black)', 'paint-down(robot1, tile_1-2, tile_0-1, black)']

INACTIVE REASON: action path invalid: The last action `paint-down(robot1, tile_1-2, tile_0-1, black)` is invalid because `tile_1-2` is not directly below `tile_0-1`, violating the precondition for the `paint-down` action. The current state's description and visualization are accurate, but the action itself is not logical or valid.
