The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our model enhances inference speed in online scenarios while maintaining competitive performance, thereby facilitating scalable and interactive 3D vision systems.

C2weakest assumption

That knowledge distilled from the dense bidirectional VGGT model transfers effectively to the causal streaming architecture without losing critical spatial consistency over long sequences.

C3one line summary

A causal transformer with key-value caching and distillation from a bidirectional VGGT model enables efficient online 4D geometry reconstruction from videos.
