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

Applying SAVANT improves VLM's absolute recall by approximately 18.5% compared to prompting baselines, and leveraging the best proprietary model within the framework enables automatic labeling of around 10,000 images to fine-tune a 7B open-source model achieving 90.8% recall and 93.8% accuracy.

C2weakest assumption

The evaluation uses a 'balanced set of real-world driving scenarios' whose selection criteria and representativeness of long-tail anomalies are not specified, which is required to support that the reported recall gains are due to the structured reasoning pipeline rather than dataset construction.

C3one line summary

SAVANT boosts VLM recall for semantic anomaly detection in driving images by 18.5% via structured reasoning and enables fine-tuning a 7B open model to 90.8% recall and 93.8% accuracy.
