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

Experiments show that SVD-Prune consistently outperforms prior pruning methods under extreme vision token budgets, maintaining strong performance even with 32 and 16 vision tokens.

C2weakest assumption

That statistical leverage scores derived from the SVD of the vision token feature matrix reliably identify tokens containing essential visual content without introducing positional bias or losing fine details on complex images.

C3one line summary

SVD-Prune selects vision tokens via SVD leverage scores to keep performance high even when pruning to only 16-32 tokens.
