The Zeta Zoo: Branch-Local Hilbert-Polya via the Trinity of UCU, SGE, and Weil-Form Transversality

Functional Stability Theory (FST) identifies a single structural pattern — functional positivity under a gauge constraint — as the common substrate of open problems in number theory, mathematical physics, and cosmology. This paper is the mathematical classification side of FST. We formalise the trinity of meta-principles governing the zeta-type branch: the Universal Convexity Uniqueness (UCU) lemma, the Semigroup-Group Equivalence (SGE) conjecture, and the branch-transversal Weil quadratic form. Within this trinity, we classify the zeta zoo — a taxonomy of zeta-type families along the SGE dichotomy (HP-BL-YES / HP-BL-NO / HP-BL-OPEN). Instances covered: Riemann zeta (NE-A, NE-B obstructions), Selberg zeta (Casimir operator), Prime-Hub (three obstructions), CRM flow-zeta, Dedekind zeta, Ihara-Petersen graph zeta. Eight further families are discussed in the outlook.
