// Updating, against the real routes.
//
// The dev server IS a git checkout of this repo, so the status route answers
// truthfully and the window can be read the way a person would read it. What is
// NOT exercised here is a real pull or a real restart: those change the checkout
// the tests are running from. Every path that would do that is stubbed at the
// fetch, and the stub is what proves the request was the right one.
