The Weinstein-domain identification conjecture for Lagrangian skeleta

From papers

Let ZZ be the open Batyrev–Borisov complete intersection with skeleton

Λ=Φ1(\eLΣ)(MS1×S),\Lambda=\Phi^{-1}(\eL_\Sigma)\cap(M_{S^1}\times S),

where S=C~0,βMRS=\partial\widetilde{C}_{0,\beta}\subset M_\R is the codimension-rr sphere introduced above, and let (S,Σ)(S,\Sigma) be the fanifold obtained by pulling back the stratification of NRN_\R by Σ\Sigma. Denote by W(S,Σ)\mathbf{W}(S,\Sigma) the Weinstein domain constructed from this fanifold. Weinstein-domain identification conjecture. There exists an isomorphism of Weinstein domains

ZW(S,Σ).Z\cong\mathbf{W}(S,\Sigma).

This conjecture would identify the A-side complete intersection with the Weinstein domain produced by the general fanifold construction, clarifying the relationship between the specific skeleton of ZZ and the broader gluing framework for mirror symmetry. The source provides no evidence of a resolution, so the conjecture remains open.
