I'm not sure what ruleset OP is using for their analysis, but with superko in place you would also need the entire history of the board to know if a move is valid.

Although rulesets might differ on what is considered a legal move, they all agree on what is a legal position: one where every connected group of stones has liberties (empty adjacent point). Furthermore, in all rulesets you can reach any legal position by playing legal moves (and passes) from the empty starting position.
