Three math manuscripts withdrawn over sign errors, prompting "even AIs make those" jokes

A batch of retractions hit three math manuscripts — on the algebraicity of Weil classes on split abelian eightfolds, Kuga–Satake correspondences for K3 surfaces, and the rational Hodge conjecture for products of K3 surfaces — reportedly due to sign errors. Blogger xuanalogue quips that "even the AIs make devastating sign errors," turning the retraction notice into a running joke bridging math and AI circles.
