October 2025: Data integrity and initialization correctness improvements for wtg/shubble. Implemented robust deduplication for GeofenceEvent inserts using PostgreSQL ON CONFLICT DO NOTHING and a safe INSERT pattern via db.session.execute (addresses issue #169). Fixed shuttle color initialization so newly created vehicles display their route colors correctly after the vehicle overlay is created (addresses issue #182). These changes reduce duplicate data, ensure accurate visualization, and enhance overall system reliability and user experience.
