Enomoto's semibrick finiteness conjecture for finite-dimensional algebras

Let Λ\Lambda be a finite-dimensional algebra. A semibrick in modΛ\operatorname{mod} \Lambda is a set of bricks whose distinct members have no nonzero morphisms between them. Enomoto's conjecture. If every semibrick in modΛ\operatorname{mod} \Lambda is a finite set, then modΛ\operatorname{mod} \Lambda is brick-finite, that is, Λ\Lambda is τ\tau-tilting finite.

This conjecture asks whether finiteness of every semibrick forces finiteness of the set of bricks. Enomoto established several equivalent characterizations of brick-finite algebras, while the stated implication remains the conjectural direction.
