Conjecture on conforming heredity data and Ringel duals

Let ARA_R be a based quasi-hereditary algebra over RR with conforming heredity data, and let ARA'_R be a Ringel dual of ARA_R. Let TA(n,d)FT^A(n,d)_\mathbb{F} and TA(n,d)FT^{A'}(n,d)_\mathbb{F} denote the corresponding generalized Schur algebras after passage to F\mathbb{F}. The conforming heredity and Ringel-duality conjecture. The algebra ARA'_R has conforming heredity data. Moreover, when dnd\leq n, TA(n,d)FT^{A'}(n,d)_\mathbb{F} is a Ringel dual of TA(n,d)FT^A(n,d)_\mathbb{F}. The conjecture addresses whether the structural heredity data survive Ringel duality and whether the generalized Schur construction commutes with that duality.
