Each step of the cascade appears here as it runs. Planner (Super) writes the task spec. Grounder looks up real sizes on the web with Tavily and Nano. Builder (Super) places objects and plans the motion. The simulator runs it and checks the goals in code. Super VL checks the scene before the robot moves; if a goal fails it watches the run and explains why, and three repair candidates are tested in the simulator.
