get
Per-destination shipment counter for the cost model. A load carrier's shipment unit is a load, so this returns the count of loads dispatched to sender — the same counter as getShipmentCounter — overriding the parent's per-demand counter, which a load carrier never increments. This is what lets the per-edge ksl.modeling.supplychain.cost.EdgeOutboundCostCalculator / ksl.modeling.supplychain.cost.EdgeInboundCostCalculator see load formation (Loading / Shipping / Unloading per dispatched load), mirroring the totalLoadWeightAccumulator / totalLoadCubeAccumulator overrides.
