Parent State ID: 58
State Depth: 7
Action Taken: change-color(robot1, white, black)
Action Reasoning: The robot needs to paint tile_2-3 black to complete row 2 before moving up. Since the robot is currently holding white, it should change to black.
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: painted white, 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)', '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)', 'change-color(robot1, white, black)']

successfully verified the action of new state 76 with the path: The last action `change-color(robot1, white, black)` is valid as all preconditions are met, and the effects are correctly reflected in the current state. The natural language description, diagram encoding, and visualization accurately represent the state after the sequence of actions taken. The action is logical for progressing towards the goal state.
