How classification and status work

Category describes physical structure and function; wheels alone do not determine whether a robot is humanoid. Product stage describes demonstrated maturity. Commercial availability describes current access: a commercial product may still be limited to pilot customers. Neither stage nor availability alone proves that a product can be purchased. Unknown facts remain unknown.
