September 2025 monthly performance summary for OpenRailAssociation/osrd. This period focused on frontend stability, data integrity, and user-centric improvements that deliver measurable business value. Key outcomes include consolidated timetable deletion logic and simulation result cleanup to prevent crashes and stale state, enhanced paced train management with occurrence ID helpers, and NGE data import enhancements to ensure accurate categorization and data relations. We also implemented frontend state persistence for train selection and projection IDs to align with URL parameters and local storage, delivering a consistent cross-session experience. A critical bug fix corrected mm-to-m conversion timing during CSV exports, and we maintained frontend dependency lockfile synchronization to prevent install/run issues. These changes collectively reduce maintenance overhead, improve data fidelity, and enable more reliable planning and operations workflows for operators and planners.
