Mathematical Foundations of the Torus Knot Architecture: Derivation of the Dimensional Registers, Hopf-Projected Conformal Weight, Dynamical Sector, and Uniqueness Criteria from the Triadic Invariant on S³

The torus knot architecture of CAT'S Theory derives Standard Model constants from T (p, q) knots on S³ via the Hopf fibration with zero free parameters. This paper derives the four mathematical foundations the architecture presupposes but has not previously derived in a single published document: (1) the dimensional registers dΨ=7, dP=8, dI=9 are uniquely forced by d=3 through extensive, relational, and orientational counting (vector addition, bilateral adjoint tensor products on SU (2) ×SU (2), and the Clifford algebra Cl (3) ) ; (2) the Hopf-projected conformal weight h=J×J*/ (k+2) is the natural weight for knot states carrying independent base and fiber quantum numbers — the standard WZW Casimir j (j+1) / (k+2) predicts zero CP violation, while the Hopf-projected weight predicts δCP=202. 5°, matching PDG at 0. 2σ; (3) the dynamical sector is the Euler–Heisenberg effective Lagrangian evaluated on field configurations with non-trivial Hopf index — the topological sector of the Standard Model's own action; (4) the four uniqueness criteria governing the T (3, 8) exhaustive search are individually required by the axioms of R=P×I×Pr≠0 on S³, each mapping to a specific factor of the Triadic Invariant.
