TRISDUCTION: A Linguistically, Topologically, and Mathematically Sealed Verification Architecture · Triaxial Orthogonality, Twelve-Gate Closure, the Quaternionic Completion, the Root Axiom, and the Master Pre-Sealed Proposition Ledger

This document presents Trisduction, a verification architecture for propositional truth grounded in a topological-geometric primary anchor with a mathematical seal closed to an independent mathematical co-seal: three seals on one architecture, linguistic-semantic at Part I, topological-geometric and mathematical issued simultaneously at Part II. The Root Axiom (RA) states that for any element of the universal domain, the substrate-level kinetic-actuation differential ΔE_k(x) is strictly positive. From RA atomic decomposition the framework derives a forced triaxial mapping onto three orthogonal verification axes: Formal-Structural (V_F), Empirical-Thermodynamic (V_E), and Epistemic-Registrational (V_ER). Friedrichs-Hodge decomposition of square-integrable differential forms provides external mathematical witness that three-way orthogonal structure on function spaces is well-defined; the specific axis-to-subspace assignment is by structural analogy, with the actual forcing of three axes coming from RA's atomic decomposition. Tetrahedral closure adds a fourth vertex (M_seal) at which the architecture seals. The complete graph K_4 directed carries twelve directed edges; each edge corresponds to one of twelve operational gates that any proposition must pass for verification, with the directed-edge-to-gate mapping uniquely forced by the Operational Content Theorem on (source role, target role) pairings. The Newton-Gregory kissing number K(3) = 12 in three-dimensional Euclidean space (Schütte-van der Waerden 1953) provides a structurally-independent theorem-grade confirmation of the twelve-fold cardinality from sphere-packing geometry, converging with the K_4 directed-edge count on twelve in 3D from disjoint mathematical content (graph theory and discrete geometry). Verdict is issued under a discrete truth function on the sign of the Gram determinant of the post-CDT residue under a regularity quadruple. The Gram matrix is positive semi-definite by construction; the verdict economy is three-state native: det>0 sealed [⟀], det=0 broken [X], regularity violation (including finite-precision det
