The Computable World Model.

A world model is only actionable when the system can model the physics of it: will this hold, fit, overheat, deflect. Real CAD and simulation are too heavy to run where the body is. CadFuture's claim is that the physics an embodied agent needs is mostly retrievable, not computable. Every query walks one cascade, lookup then closed-form formula then sparse solver then a model only as a last resort, over a single graph that carries geometry, the physics fields, tolerances, live-twin state, and the agent's own interaction. The same full engineering model runs from a sub-five-milliwatt neuromorphic chip to a workstation; execution adapts, the engineering truth does not.
