================================================================

Central claims verified:

  3.  f is strictly convex on (0,∞): f''(x) > 0
  4.  The discriminant of the quadratic factor 4x²+x+1 is negative
      ⇒ π is the UNIQUE positive real root of f(x) = μ
  5.  The Nicomachus formula: μ = ∑_{d=1}^{3} (d+1)^{(d-2)_+} π^d
  6.  Bézout counts c_d = (d+1)^{max(d-1,1)} for d ∈ {1,2,3}

  16. Layer fractions sum to 1
  17. Physical α = 1/μ lies in (0,1)
  18. Coupling α·ρ(r) is positive for r ∈ (0,1]
  19. R1–R8 coverage: operator components are spectral on correct spaces
  20. The Nicomachus factorisation cross-check: μ = 4π³+π²+π = (d+1)^{(d-2)_+}·πᵈ
  21. GSP Axiom G4: M[ρ] = μ (paper 00 reconstruction)
  22. Moment μ₀ = μ
  23. Moment μ₁ = 16π³/5 + 3π²/4 + 2π/3
  24. Gravity formula: log(M_Pl/m_e) = (3π/20)·μ₁/(1 - μ₁·α²)
  25. κ = α^(5/4) approximation
  26. Oscillation floor 4π < E_self
  27. Self-lensing energy E_self < 4π + 1
  28. Polynomial factorisation: f(x) = x·(4x²+x+1)
  29. At x=0: f(0) = 0 < μ
  30. At x=π: f(π) = μ (again, different assertion path)
  31. Strict inequality f(x) < μ for all x ∈ (0,π) (sample check at x=3)
  32. Strict inequality f(x) > μ for x > π (sample check at x=4)
  33. Hopf projection identity: v = (a²+b²)-(c²+d²) for |q|=1
  34. Lapse m = √(1-v²) is real for |v| < 1
  35. Breath / observation duality: BREATH_PERIOD/μ = π
  36. Hierarchy level 1: π²·μ (level 2 in breathing hierarchy)

  38. Chebyshev T_3(t): exactly 3 real roots in (-1,1)
  39. Chebyshev T_4(t): exactly 4 real roots in (-1,1)
  40. c_3 = 16 = 4² = 2⁴ (coincidence confirmed numerically)
  41. c_d from uniform formula vs Paper 08 heuristics agree for d=1,2,3
  42. The polynomial f(x)-μ has exactly one real root in (3,4) (i.e., x=π)
  43. Discriminant of 4x²+x+1 is -63 (exact integer check)
  44. Uniqueness: no integer n satisfies n(n+2) = μ (S³ spectral gap)
