Cube-compatible identification conjecture for HOMFLY-PT and knot Floer homologies

From papers

Let DD be a braid diagram for a knot KK, and let SS be a singular resolution of DD. Define HH(S)H_H(S) to be the HOMFLY-PT homology of SS, and define HF(S)H_F(S) to be the homology of the complex assigned to SS by the knot Floer cube of resolutions.

Cube-compatible identification conjecture.

There is an isomorphism

HF(S)HH(S).H_F(S)\cong H_H(S).

Moreover, this isomorphism commutes with the induced edge maps in the cube of resolutions.

Such an identification would explain the relationship between the HOMFLY-PT and knot Floer cube constructions at the level of individual singular resolutions and their transition maps. The supplied context does not state whether this conjecture has been resolved.
