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

Ozone reduces experiment setup time by 85%, achieves 91% cross-city transfer efficiency for safety models, and improves cross-dataset reproducibility to within 3% variance.

C2weakest assumption

That the proposed canonical data schema with oriented bounding boxes and pre-computed surrogate safety measures can represent all relevant information from the original heterogeneous datasets (NGSIM, highD, CitySim, UTE) and simulators without critical loss or bias.

C3one line summary

Ozone unifies four trajectory datasets into a canonical format with standardized schemas and provides CARLA-based benchmarking, claiming 85% faster experiment setup and 91% cross-city transfer efficiency.
