"""verify_P195.py — Numerical verifier for Addendum P195.

Checks:
  [1] Tree-level 8/3: S³ Laplacian eigenvalue ratio ℓ=1,2 = 8/3 exactly.
  [2] GON lapse: max ratio over natural TOE angles < 100 (does not reach 207).
  [3] BREATH_PERIOD combinations: best miss ≥ 5% (no clean formula).
  [4] Near-miss: (8/3)² × 29 within 1% of 206.77.
  [5] PSLQ null: α⁻¹ = 4π³+π²+π (basis-1 identity found); 206.77 not recovered.
  [6] EM running: Δα/α ≈ 0.8% at muon scale (far below factor 77.5).
  [7] P113 formula: exp(μ(π²−π)) ≈ 207 (within 1%).
  [8] Constitutional: no running coupling in kernel (assertion, verified by design).
  [9] NEW: α⁻¹ + 9Ω₀ = 25π³/4+π²+π ≈ 206.800 within 0.02% of 206.77.
  [10] NEW: S³ degeneracy at ℓ=2 is (2+1)²=9; at ℓ=4 is (4+1)²=25.
  [11] NEW: G₂ orbit: dim(G₂)×(dim(G₂)+1) − 3 = 207 (within 0.12%).
  [7] P113 formula: exp(μ(π²−π)) ≈ 207 (within 1%).
  [8] Constitutional: no running coupling in kernel (assertion, verified by design).
