✓ Portable graph bundle live · download bundle · merged state

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

Under a fixed backbone and frame budget, CATS consistently outperforms prior lightweight approaches such as AKS on LongVideoBench and VideoMME. CATS retains approximately 93-95% of MIRA's performance while requiring only 3-4% of its preprocessing cost.

C2weakest assumption

That curvature of query-frame relevance scores reliably identifies salient events and surrounding context across diverse video domains without systematic omission of critical information.

C3one line summary

CATS uses temporal curvature of query-frame relevance to select informative frames, achieving 93-95% of heavy multi-stage accuracy at 3-4% of the preprocessing cost on long-video benchmarks.
