World 6 Boss · Usability Heuristics
One screen, several laws, no hints — the checkpoint that proves this world stuck.
A project-tracker screen hides ten usability problems among honest elements — exactly one per Nielsen heuristic. Find each one, name the heuristic it breaks, and file the fix. One full Heuristic Sweep, like a real design review.
