    """A single run combining pickups and deliveries for one driver.

    Lifecycle:

        draft → planned → in_progress → completed → (cancelled)

    Dispatch drops pickup requests and deliveries on the route as stops,
    re-orders them using the `sequence` handle, then hands the route to
    the driver. The driver ticks off stops as they work, and the route
    captures total distance (km) and elapsed time for costing.
