Parent State ID: 4
State Depth: 3
Action Taken: down(robot1, tile_1-1, tile_2-1)
Action Reasoning: The robot should move down to tile_2-1 and paint it black as allowed. This aligns with the goal of painting the last row first.
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: occupied by robot1 holding color 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)']

successfully verified the action of new state 10 with the path: The last action `down(robot1, tile_1-1, tile_2-1)` is valid because all preconditions are satisfied: the robot was on `tile_1-1`, and `tile_2-1` was clear. The effects are correctly reflected in the current state, with the robot now on `tile_2-1` and `tile_1-1` clear. The natural language description, diagram encoding, and visualization accurately represent the current state.
