1// _ttt_diag.nx -- diagnostic twin of nx_tictactoe_test assertion 8: play the
2// 9-move draw sequence, then PRINT each cell, the per-move try_apply results,
3// and the final outcome.  Run under bash vs under the NishiLang exec probe to
4// see exactly where the two execution contexts diverge (2026-06-09).
