When this article was originally published on 29 December 2025 in Compositio Mathematica, it contained a typo on the final line of page 3018. There, the sentence ‘4-fold is algebraic’ should read ‘For such curves, it turns out that we require a nontrivial case of the Hodge conjecture to apply Theorem B, namely that a certain Weil class on an abelian 4-fold is algebraic.’
The publisher apologises for this error.
