## Summary

SpatialBrain is a framework that retains experience in spatial reasoning decisions on a fixed vision-language backbone. 3DFusionMemory fuses current-scene observations into queryable spatial relations, the Spatial Skill Library provides reusable tool procedures, and Spatial Cognition associates task conditions with experience about when and how to use memory and skills; completed trajectories are abstracted into process records and consolidated between task blocks.
