SCENARIO

You've joined Shoply. Customers move house, and a shipping label has to use the address that was current when the order was placed — while a customer can legitimately hold several addresses at once. Then explain: what happens to an order that has already shipped when the customer edits the address it was shipped to?

your model must answer

01A customer's current default shipping address?
02The address used for order X, as of when it was placed?
03A customer's full address history, with the dates each was valid?

This exercise’s brief could not be loaded.The guided questions and their model answers come from the review service. It looks like it is not reachable — start it with pnpm dev:api and reload.The canvas below still works, so you can model now and run the review once the service is up.
