Conjecture B for X₁₀ and its genus-two mirror

We prove Conjecture B of Akhtar--Coates--Corti--Heuberger--Kasprzyk--Oneto--Petracci--Prince--Tveiten unconditionally for the normalized family of maximally mutable Laurent polynomials with prescribed T-binomial edge coefficients associated with the degree-10 orbifold del Pezzo hypersurface X₁₀(1,2,3,5). An explicit S-extended quantum-period calculation determines the affine mirror map $λ=a-346$ and proves that the regularized quantum period equals the classical period as a formal power series throughout the family.
