This monograph revisits a range of classical problems in arithmetic, geometry, and transcendence through the lens of Operations Theory, with the central goal of correcting their structural placement within the operational landscape. The key result is a systematic separation of the Hyper Core (HC) and Symmetric Core (SC) ladders, which are shown to coincide only at low ranks and to diverge decisively beyond addition and multiplication. A principal correction concerns the arithmetic–geometric mean (AGM). The classical Gaussian AGM is identified as a Hyper‑Core mean at rank R=1.5, while a related operation AGM(a+b,ab) appears as a shared HC/SC operation. This distinction resolves long‑standing ambiguities in the operational interpretation of elliptic integrals, modular parameters, and intermediate ranks, and clarifies which tools are appropriate for BSD‑type phenomena. With the corrected taxonomy in place, the monograph re‑examines several well‑known conjectural domains (including BSD‑related structures, Goldbach, abc, Schanuell, Waring, Engel, and transcendence questions), not to claim solutions, but to identify which operational core governs each problem and to isolate the genuine remaining obstruction. Several problems traditionally treated as Symmetric‑Core phenomena are shown to be Hyper‑Core problems in disguise. The volume explicitly corrects earlier internal misidentifications (such as confusing commutative tetration with toweration or HC powering with SC powering) and propagates these corrections consistently. M20e thus functions as a boundary‑setting and alignment volume, removing category errors and providing a clean operational map for subsequent work in the series.
