A part it has no fresh report for is not shown as it last was. The damage-control board's missing state is "we do not know", so a room that never reported is hatched and marked XX, the airliner system page's mark for a value that is not available, and one whose report is old is faded with its age. Flow is never drawn through a part nothing vouches for: it moves only through parts that are fresh and open, a pipe is drawn dry only where a known closed valve or stopped pump proves it, and everything else is undetermined, broken and still. Here PUMP B is stopped, so its branch is proven dry, and V3 never reported, so nothing past it is claimed.
