delivery
Endpoint invoked when a demand reaches Delivered with this node as its destination. Owns the Delivered → Stored (or Delivered → Shipped for multi-hop pass-through) transition.
Default: PassThroughStorageEndpoint (immediate store()). A node modelling unload time replaces this with a Dock; a pass-through cross-dock replaces this with a routing endpoint.
