Case contract

Input: {"seats": [clockwise order from the dealer's left], "hands": {player: {"up": [...], "down": [...]}}, "folded": [...]}. On fourth street and later the live player with the best exposed hand acts first. Exposed hands rank by group shape (quads > trips > two pair > pair > no pair), then by group ranks; only up cards count. Exact ties go to the player earliest in seat order.

Why this case matters

Acting order on later stud streets follows the best board, not position.

One recorded failure
