Required features compared case-sensitively · case 04

A requirement for "Lab" is never satisfied by a room tagged "lab".

Member previewVariant 4 · 3 implementations · 8 checks per implementation

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.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
regression: feature case folding 1	`[["MATH101", "R2", "features", ["accessible", "computers"]], ["MATH101H", "R3", "features", ["Lab", "computers"]], ["*", "R3", "capacity", [3, 1]]]`	`[["MATH101", "R2", "features", ["accessible", "computers"]], ["MATH101H", "R3", "features", ["computers", "lab"]], ["*", "R3", "capacity", [3, 1]]]`	Failed
