The Two-Parameter Universe: Artosphere Lagrangian, chi-boson dark matter at 58 GeV, and the theorem on MPl irreducibility

Paper VI in the Artosphere series. We address the three remaining obstacles to a Theory of Everything within the Cl(9,1) framework. 1. The Artosphere Lagrangian (Wall 1 — CONSTRUCTED) LArt is assembled from the Chamseddine-Connes spectral action with the VArt potential. The scalar field s lives on the hyperbolic disk [0, 1/φ) with Fubini-Study metric (1−s−s2)−2, creating geometric confinement analogous to the speed of light in special relativity. Key discovery: the Yukawa derivative at the VArt vacuum equals φ3/2 exactly, from the identity 2φ−3 = 1/φ3. 2. Dark Matter: χ-boson at 58 GeV (Wall 2 — PREDICTED) The χ-boson (Mχ = vEW/φ3 = 58.1 GeV) is identified as the dark matter candidate with zero free parameters. Stability is guaranteed by Z2 symmetry from the functional equation ξArt(s)=ξArt(1−s). Direct detection cross-section σSI ≈ 5×10−47 cm2 is at the XENONnT/DARWIN frontier. Relic abundance Ωh2 ≈ 0.08–0.18. Four falsifiable tests stated. 3. MPl Irreducibility Theorem (Wall 3 — PROVEN) We prove that MPl cannot be derived from purely algebraic data (φ + Cl(9,1)). The Planck mass cancels from all self-consistency equations. This is a structural theorem (dimensional analysis), not a limitation. Even string theory requires one dimensionful input. The Artosphere is therefore a two-parameter theory: φ (form) + MPl (scale) → ~35 physical outputs.
