Case contract

Input [board, dead_points, komi_tenths]. Remove dead stones (no prisoners in area scoring), then area = remaining stones + regions bordered by one colour. Return [black, white, margin_tenths].

Why this case matters

Go servers and scoring tools compute this value automatically; a wrong answer changes a game result.
