Generalized Cambrian denominator-vector theorem

Let $B$ be an exchange matrix, and let Theorem~ denote the source's theorem identifying the combinatorial Cambrian data with denominator vectors of cluster variables. Generalized Cambrian denominator-vector theorem. Theorem~ holds even when $B$ is not of finite Cartan type. The source presents this as a conjecture implied by the $\nu$-conjecture, while the supplied text does not state that it has been resolved beyond finite Cartan type.
