Teaching Case — A Budget With Nothing to Check It Against

The rack states a power budget and not one device states its draw, so there is nothing to add up. Reported as a GAP naming what is missing rather than as a budget that was met — a green tick over an unknown is worse than no tick at all, and a reader who sees findings and no gaps takes the reading as total. The occupancy half of the analysis still runs and still finds every device in a unit of its own, because two questions that can be answered separately should be.
