Natural algebra action on matchings for alternating Kasteleyn matrices

From papers

Let AA be a nonsingular alternating matrix, and let DD be the matrix-algebra deformation of C[cokerA]\mathbb{C}[\operatorname{coker} A] defined by the twisted relations in the paper. Let GG be a planar graph with nonempty matching set PP, and suppose that AA is a Kasteleyn matrix of GG. Kasteleyn algebra-action conjecture. There is a natural action of DD on C[P]\mathbb{C}[P], possibly depending on how GG is embedded in the plane. Such an action would provide the algebraic structure underlying the proposed quantum-bijection interpretation of perfect matchings. The source gives no proof or resolution, so the conjecture remains open.
