Case contract

Input an SGF RE string. "0", "Draw", "Jigo" -> ["draw", 0, "score"]; "Void" -> ["void", None, "none"]; C+R/Resign, C+T/Time, C+F/Forfeit (case-insensitive) -> [C, None, reason]; "C+" -> [C, None, "unknown"]; C+digits with optional one-digit fraction -> [C, tenths, "score"]; else unknown.

Why this case matters

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

One recorded failure
