Polygons with two interior lattice points
The forty-five lattice-equivalence classes of convex polygons with exactly two interior lattice points. Select a polygon to see all rulings in genera 0, 1, and 2.

Each entry uses one fixed SL₂(ℤ) representative and one fixed vertical direction for every ruling.

These diagrams come from direct ruling certificates. No tropical count or previously known answer is used. The disk/annular split belongs to the displayed torus realization.
Every ruling for this entry uses exactly the polygon and the fixed Λ shown above. Annular eyes are normalized only in lifted coordinates and then mapped back.
