Resolved native stop-ID crosswalk

Native stop IDs resolved by explicit source IDs. Each native GetStop response supplies SrcStopID, which joins to current GTFS stop_id. Names and coordinate differences are included for review. Native IDs must not be assumed to share the GTFS identifier namespace.

Marker and navigation coordinates always use GTFS stops.txt. Native API coordinates are retained only for comparison; OnSign locations are unused. Native stops that differ from GTFS by more than 25 metres are flagged for coordinate review. This does not invalidate their explicit ID mapping. Kiosk device positions remain unknown; station reference points and mapped bays are clearly labeled.
