Dual robot arms with high-reasoning model fail 20 attempts at rolling a joint in sim

For fun, the author gave Astra two Franka FR3 arms, sharpa hands, and 512 gizmo-generated flakes in Isaac simulation: RGB input → wrist poses + fingertip targets → IK → contact physics.
Even on high reasoning, after 20 attempts the model still couldn't roll the simulated joint. As they put it: "apparently dexterity is not included in the token price."
