Universality conjecture for the strongly co-Stone hull of a residuated lattice

Let AA be a residuated lattice, let A~\tilde{A} be its strongly co-Stone hull, and let ϵ:AA~\epsilon:A\to\tilde{A} be the canonical morphism. For a subset XAX\subseteq A, write XX^{\top} for its associated co-annihilator; similarly, for subsets of another residuated lattice, use the same notation. A residuated-lattice morphism is a map preserving the residuated-lattice structure. Universality property of the strongly co-Stone hull. For every strongly co-Stone residuated lattice A1A_{1} and every residuated-lattice morphism f:AA1f:A\to A_{1} satisfying

f(X)=f(X)f(X^{\top})=f(X)^{\top}

for every XAX\subseteq A, there exists a unique residuated-lattice morphism f:A~A1\overline{f}:\tilde{A}\to A_{1} such that

fϵ=f.\overline{f}\circ\epsilon=f.

This asserts that A~\tilde{A} is universal among strongly co-Stone residuated lattices receiving a morphism from AA that preserves co-annihilators. The source provides no evidence resolving this statement, so its status is unclear.
