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

Simulation results across diverse one-way traffic scenarios demonstrate the framework's robustness, responsiveness, and suitability for chaotic, unstructured traffic.

C2weakest assumption

The 360° zone-based perception module provides reliable spatial distribution data on neighboring vehicles even in highly unpredictable driver behavior and dense conditions.

C3one line summary

A situation-aware hybrid feedback-predictive controller enables autonomous navigation in dense unstructured traffic by deriving reference speeds from braking distances and tracking virtual lanes from vehicle distributions.
