The office twin receives simulated Go2 and G1 robots. Calibration, movement, scene reconstruction, lighting and grasping failures precede a humanoid fall when the arm is forced overhead. All robot results are simulation.
Go2 and G1 robots entered the office twin, and the experiment became a sequence of concrete problems: room alignment, crawling instead of walking, reconstructed geometry, lighting and a gripper closing on air.
The Go2 manipulation attempt needed its own recovery work. The G1 could walk, but forcing an arm overhead exposed a balance failure. A capability that works in one motion does not automatically survive another.
All robot-side evidence is simulated. The released G1 fall and fallen-robot drag were reconstructed with an open velocity policy and model, not recovered as footage of the original run. The result is a useful account of integration and failure, with grasp repeatability and physical deployment still unresolved.
