The exchange-graph conjecture for cluster algebras

Let ${\mathcal A}$ be a cluster algebra with initial exchange matrix $B$. Its exchange graph is the quotient of the regular tree of seeds by simultaneous permutations of cluster variables, coefficients, and the rows and columns of the exchange matrix. Exchange-graph conjecture. The exchange graph of a cluster algebra depends only on the initial exchange matrix $B$. This conjecture asserts that the exchange graph is independent of the chosen coefficients or realization of the cluster algebra, once $B$ is fixed. The supplied text gives no resolution status.
