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 on diverse benchmarks show that VISD consistently outperforms strong baselines, improving answer accuracy and spatio-temporal grounding quality. Notably, VISD reaches these gains with nearly 2x faster convergence in optimization steps.

C2weakest assumption

The video-aware judge model produces diagnostically meaningful, unbiased privileged information that can be safely used for token-level supervision without introducing new failure modes or reward hacking.

C3one line summary

VISD adds structured privileged feedback from a judge model and a direction-magnitude decoupling trick to let VideoLLMs learn token-level credit assignment while keeping RL stable, yielding higher accuracy and roughly 2x faster convergence on video reasoning benchmarks.
