A dev run is for working on the client, and the data worth working against lives on the DHP. Deciding this by "is anything installed" guessed wrong both ways: a PC with an old install silently ran on stale local data, with nothing on screen saying so, while a PC with none was refused outright. Now: dev mode + the DHP answering -> the client runs from the checkout against the DHP's API and tiles, installed or not. No DHP -> the local stack, as before.
