Remark: Withdrawn. Kuga–Satake correspondences for K3 surfaces

WITHDRAWN on 7 October 2026. Algebraicity of Kuga–Satake Correspondences for K3 Surfaces is not a current result. A sign error invalidated a stabilization-trace cancellation, and the catalogue removed the claim from the standing list. The authors are OpenAI. This record is not a theorem of the Enter series and not a premise. O.1 stays NOT_CLOSED. No quantum coefficient is admitted. No compilation is asserted.
