This note presents a structural epistemological critique of Blitz, Gover, Kopiński & Waldron (2026), "The Dirichlet-to-Neumann map for Poincaré–Einstein fillings," Rev. Mat. Iberoam. 42(1), 229–260. The paper's internal mathematics is not disputed. Five structural deficiencies are identified: (1) dimension treated as free parameter, (2) Poincaré–Einstein existence assumed, (3) triadic tractor decomposition used without ontological justification, (4) renormalized volume dependent on unexplained divergence subtraction, (5) zero empirically falsifiable predictions. All five are resolved by the single structural input d=3 within CAT'S Theory, which derives Standard Model observables from torus knot topology on S³ via Hopf fibration with zero free parameters, including neutrino mixing parameters consistent with JUNO (2025).
