The classification conjecture for non-orientably fillable torus knots

Let T(p,2)T(p,2) denote the torus knot with relatively prime parameters pp and 22, where p<0p<0. A torus knot is non-orientably fillable if it admits a non-orientable Lagrangian filling.

Classification conjecture. The only non-orientably fillable torus knots are of the form T(p,2)T(p,2) with p<0p<0.

This conjecture proposes a complete description of non-orientably fillable torus knots, extending the cases established in the paper and excluding all other torus-knot parameters. Its resolution would clarify the limitations of non-orientable Lagrangian fillings beyond the explicitly constructed examples.
