## Summary

REACT is a framework for learning deployable humanoid-human interaction policies from human-human demonstrations, using semantic contact structure as the supervisory signal that links demonstration processing, interaction learning, and onboard control. It uses a VLM-guided contact modeling and retargeting pipeline to identify semantic contacts and transfer them onto humanoid-human geometry, then distills a privileged interaction policy into an egocentric depth policy that relies entirely on onboard sensing, and introduces a generative partner state modeling objective to predict partner motion from occluded viewpoints.
