## Summary

μ0 is a scalable world model based on 3D traces. Rather than predicting dense pixels or directly modeling actions, it forecasts smooth 3D trajectories for salient interaction points such as objects, tools, hands, and contact regions, forming a compact, embodiment-agnostic motion interface.
