UpdateShipmentTrackingPayload

"""
Result of a locked shipment tracking update; no aggregate completion or item receipt quantities are inferred.
"""
type UpdateShipmentTrackingPayload {
  """
  The updated shipment, with shippedAt stamped on the first move to PICKED_UP/IN_TRANSIT and deliveredAt stamped on DELIVERED. Null when `errors` is non-empty.
  """
  shipment: ShipmentState
  """
  Reserved nullable compatibility field. Tracking alone does not establish aggregate order completion and currently returns null.
  """
  order: OrderState
  """
  Per-field validation errors — an unknown shipmentId, or a status transition the shipment's state machine forbids. Empty on success; when non-empty nothing was written.
