What they are
Each one is a single point on the map marking a physical thing at or near a building. They do not belong to an address the way an entrance does — mark them wherever you find them, and a nearby address is attached automatically when there is one.
- Use them for anything a courier or responder would want to know before arriving.
- One point per thing — a stairwell and the gate in front of it are two separate assets.
- Place them even where no path exists yet; they still make the next arrival easier.
