2. Trip cancelled part‑way through:
   • If the service runs from the first stop to stop n (where all passengers must alight and boarding is forbidden) – for stops n+1 to the final stop, schedule_relationship is set to SKIPPED.
   • If the service runs from stop n to the final stop (where passengers may board at n onwards) – for stops 1 to n−1, schedule_relationship is set to SKIPPED.
