Infinite boundary depth conjecture for Maslov-zero Lagrangian tori

Let LML\subset M be a Maslov 00 Lagrangian torus, and let C(L,M)C^*(L,M) be its Floer complex with differential satisfying

(C(L,M))={0}.\partial(C^*(L,M))=\{0\}.

Here τ(L)\tau(L) denotes the relevant boundary-depth invariant. Infinite boundary depth conjecture. Then

τ(L)=.\tau(L)=\infty.

This conjecture would remove the exactness assumption from the preceding result and establish the key condition needed for the reconstruction problem for general SYZ fibrations.
