set_position

Put a position on the board from a FEN, including a FEN returned by the app's dedicated photo recognizer. The board enters setup mode and runs its rules self-check (piece counts, advisors and elephants on reachable points, pawns not behind their river, kings inside the palace, and kings not facing). Invalid points come back listed so you can fix only those squares with place_pieces. The human must press Confirm to start analysing. Side to move cannot be inferred from a still photo, so ask the human if it is unknown.
