This preprint develops a Hilbert–Pólya spectral construction for the Riemann xi-function, with a unified analytic, operator-theoretic, and determinant argument aimed at the critical-line conclusion for the nontrivial zeros. The present version has been polished for submission to the Annals of Mathematics and has been submitted there for editorial consideration and review.
