Rule of thumbMandatory
Every habitable room has at least one door
ADJ-DOOR-01Description
Every habitable room must have at least one door (interior_door or interior_open) connecting to another non-bathroom room.
Why this exists
A room with no door isn't a room — it's a closet at best, an enclosed void at worst. Reachability from the entry depends on every habitable room having a connecting opening.
