Query: Cantor-Bendixson ranks of countable SFTs   We show that the possible Cantor-Bendixson ranks of countable SFTs are
exactly the finite ordinals and ordinals of the form $\lambda + 3$, where
$\lambda$ is a computable ordinal. This result was claimed by the author in his
PhD dissertation, but the proof contains an error, which is fixed in this note.
