## Notes

- **Time zone**: each scan has a `utcOffset`, so `timestamp` is exact. Dates are US format (`mm/dd/yyyy`).
- **Signed by**: `Delivered - Signed By: <name>` is split into the `Delivered` description and `signedBy`.
- **Auto-detection**: 9-digit PROs are shared with other LTL carriers, so pass `?carrier=southeasternfreightlines`. Seven-digit PROs are answered `not_found` without calling SEFL.
