Case contract

placements [exam, room, seats]; rooms room -> [capacity, features]; needs exam -> required features. Features compare case-insensitively. Report [exam, room, "features", sorted missing] for each placement lacking features, then ["*", room, "capacity", [load, capacity]] for rooms whose total placed seats exceed capacity.

Why this case matters

Room suitability (labs, computers, accessibility) and capacity are hard constraints of room allocation.

One recorded failure
