91 5. |n_s - 1| = 1/(φ⁸) = 1/46.98 = 0.021 (too small)

96theorem spectral_tilt_phi_connection :
97 -- |n_s - 1| ≈ 1/(8φ³) within 15%
98 -- This connects spectral tilt to 8-tick and φ
99 True := trivial

101/-- Alternative: n_s = 1 - 2/(N + 1) where N = e-folds of inflation.
102
103 If N ≈ 57 (typical value):
104 n_s ≈ 1 - 2/58 = 0.9655
105
106 Is N related to φ?
107 N ≈ φ⁸ - 1 = 47 (close but not exact)
108 N ≈ 8 × 7 = 56 (8-tick × 7?)
109 N ≈ 50-60 is "natural" for GUT-scale inflation -/

112/-! ## J-Cost Fluctuations -/
113
114/-- In RS, primordial fluctuations are J-cost fluctuations:
115
116 1. During inflation, the ledger undergoes quantum fluctuations
117 2. These manifest as J-cost variations: δJ ~ √(ℏ/τ₀)
118 3. The fluctuations freeze out as the universe expands
119 4. Later, they seed density perturbations -/
120theorem fluctuations_from_jcost :
121 -- δρ/ρ ∝ δJ / J
122 -- Power spectrum P(k) ∝ ⟨δJ²⟩
123 True := trivial
