Feb 1, 2026February 2026 focused on improving data integrity for trajectory handling in the SCM-NV/PLAMS repository. A critical bug fix addressed redundant header writes in RKFTrajectoryFile when the trajectory position is zero, ensuring headers are written only once and preventing potential data corruption. This work stabilizes Molecule section handling and reduces downstream risk in trajectory analysis.
