Homogeneous-coordinate-ring conjecture for the mirror filtration

From papers

Let UYU\subset Y be an snc partial minimal model, let WW be an effective ample divisor supported on the boundary, and let A~θ\widetilde A_{\theta} be the graded subring obtained from the filtration defined by the tropical orders along the boundary components. Homogeneous-coordinate-ring conjecture. One fibre of A~θ\widetilde A_{\theta} is the homogeneous coordinate ring of (Y,O(W))(Y,\mathcal O(W)).

This conjecture proposes that the mirror-algebra filtration recovers projective geometry of the partial minimal model. The supplied text gives no evidence of resolution.
