Binary-invariants conjecture for minimal bounded width algebras

Let A\mathbb{A} be a minimal bounded width algebra. Define

Inv2(A)\operatorname{Inv}_2(\mathbb{A})

to be the collection of subalgebras of A×A\mathbb{A}\times\mathbb{A}. Two algebras are term equivalent when they have the same term operations, up to the corresponding choice of basic operations.

Binary-invariants conjecture. Among minimal bounded width algebras, A\mathbb{A} is determined up to term equivalence by Inv2(A)\operatorname{Inv}_2(\mathbb{A}).

The conjecture would say that the binary subalgebra structure completely determines a minimal bounded width algebra up to term equivalence. The supplied text gives no evidence of a proof or counterexample.
