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

We propose video retrieval augmented generation (VRAG) with explicit global state conditioning, which significantly reduces long-term compounding errors and increases spatiotemporal consistency of world models.

C2weakest assumption

The paper assumes that insufficient memory mechanisms are the primary cause of incoherence in current video world models and that retrieval of past clips plus explicit global state can overcome this without introducing new inconsistencies or requiring full retraining.

C3one line summary

The work introduces video retrieval augmented generation (VRAG) with explicit global state conditioning to reduce compounding errors and improve spatiotemporal consistency in interactive video world models.
