nx_folkgame_align_gate.nx -- GATE for the align family of nx_folkgame_lib. THE LOAD-BEARING TOOTH IS T5. The number of possible games of Tic-Tac-Toe -- counting every distinct sequence of moves and stopping each line the moment somebody wins -- is 255,168. That is a PUBLISHED COMBINATORIAL CONSTANT, not a number this estate computed and then asserted about itself. A move generator that is wrong anywhere (one illegal move admitted, one legal move missed, a win not detected, a draw detected early) cannot land on it by accident. Every other tooth here checks a shape; T5 checks the RULES. The neg-controls are equally deliberate: three malformed specs that MUST be refused, because a parser that accepts everything passes every positive test ever written against it. license_tier: ORIGINAL No hw writes (Rule 26).
