Classification of rank-two simple Lie algebras in Verlinde categories

Let p>0p>0, let Verp+{\rm Ver}_p^+ be the relevant Verlinde category, and let g\mathfrak{g} be a simple Lie algebra in Verp+{\rm Ver}_p^+ containing a simple Lie algebra s\mathfrak{s} such that s\mathfrak{s} acts on g\mathfrak{g} canonically. Define the rank of g\mathfrak{g} to be its length as an s\mathfrak{s}-module, equivalently as an object of Verp+{\rm Ver}_p^+. Rank-two classification conjecture. There are no simple Lie algebras of rank 22 in Verp+{\rm Ver}_p^+ other than the listed series and exceptional examples: A2A_2 for p7p\geq7, B2=C2B_2=C_2 for p11p\geq11, D2D_2^* for p11p\geq11, G2G_2 for p17p\geq17, and the exceptional cases E2E_2^* at p=23p=23 and E2E_2^{**} at p=37p=37. This is a proposed classification of the rank-two simple Lie algebras occurring in the Verlinde category.
