During October 2025, E. Fuchey enhanced the Kalman filter within the JeffersonLab/coatjava repository by introducing a dynamic, configuration-driven approach to magnetic field handling. Instead of relying on a hardcoded value, the filter now retrieves the magnetic field from the RUN::CONFIG data bank within the AHDC engine, allowing the software to adapt to varying experimental conditions. This update, implemented in Java and leveraging skills in data analysis and physics simulation, improved the robustness and accuracy of physics reconstruction. The work addressed maintenance concerns related to static assumptions and contributed to more reliable data quality for downstream scientific analyses.
