Open Gromov–Witten sum-formula conjecture for Lagrangian real projective 3-spaces

Let $X$ be an almost Calabi–Yau 3-fold and let $L\cong \mathbb{R}P^3\subset X$ be an embedded Lagrangian. For odd classes $\beta\in\Pi_2(X,L)$, the open Gromov–Witten invariants $N_{\beta}^{sym}$ are considered in relation to an almost Calabi–Yau $X_{out}$ constructed from $X$ and homology classes $F_{\beta',k}\in H_2(X_{out},\mathbb{Z})$ constructed from $\beta'$. Open Gromov–Witten sum-formula conjecture. For odd classes $\beta\in\Pi_2(X,L)$, the invariants $N_{\beta}^{sym}$ can be expressed as a function of ordinary Gromov–Witten invariants of $X_{out}$, using the homology classes $F_{\beta',k}\in H_2(X_{out},\mathbb{Z})$. The proposed relation would connect open invariants for Lagrangian real projective 3-spaces with ordinary invariants of a symplectically cut-out manifold, but the source does not provide a formula or establish the claim.
