The direct Dirichlet bound at re = 2\u221an (DL-6) \u2014 the I_I /\nV_right zeta factor WITHOUT certifying dirichletC2 \u2264 0.57.\n\nThe I_I charge in IIMaj is 0.57\u00b72^{\u2212(2\u221an\u22122)} = 2.28\u00b72^{\u22122\u221an} (the\n(6.10)-route constant |\u03b6\u2032/\u03b6(2)|). Proving dirichletC2 \u2264 0.57 directly\nneeds a ~100-prime partial-sum build (the antitone-integral tail is too\nfat). AVOIDED here: the DIRECT Dirichlet-series bound at re = 2\u221an gives\nlog2-leading + a 3^{\u2212(2\u221an\u22122)} tail (dirichletC2 \u2264 1), which is \u2264\n0.57\u00b72^{\u2212(2\u221an\u22122)} for n \u2265 5 \u2014 the IIMaj charge exactly. -/\n\n/-- The Dirichlet majorant at s = 2\u221an (summable since 2\u221an > 1). -/\ndef dirichletCX (n : \u2115) : \u211d :=\n  \u2211' m : \u2115, \u2016LSeries.term (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n    ((2 * Real.sqrt (n : \u211d) : \u211d) : \u2102) m\u2016\n\n/-- \u2016\u03b6\u2032/\u03b6(2\u221an+it)\u2016 \u2264 dirichletCX n for n \u2265 1 (the LSeries majorant). -/\nlemma norm_logDeriv_zeta_le_dirichletCX {n : \u2115} (hn : 1 \u2264 n) {t : \u211d} :\n    \u2016logDeriv riemannZeta (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I)\u2016 \u2264\n      dirichletCX n := by\n  have h1 : (1 : \u211d) \u2264 Real.sqrt (n : \u211d) := Real.one_le_sqrt.mpr (by exact_mod_cast hn)\n  have hs1 : (1 : \u211d) < (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I).re := by\n    simp\n    linarith\n  have h1' : -logDeriv riemannZeta (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I)\n      = LSeries (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n        (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I) := by\n    have h2 := ArithmeticFunction.LSeries_vonMangoldt_eq_deriv_riemannZeta_div hs1\n    rw [logDeriv, Pi.div_apply, h2]\n    ring\n  have hsumX : Summable (fun m : \u2115 =>\n      \u2016LSeries.term (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n        (((2 * Real.sqrt (n : \u211d)) : \u211d) : \u2102) m\u2016) := by\n    rw [summable_norm_iff]\n    apply ArithmeticFunction.LSeriesSummable_vonMangoldt\n    rw [show (((2 * Real.sqrt (n : \u211d) : \u211d) : \u2102).re) = 2 * Real.sqrt (n : \u211d) from by simp]\n    linarith\n  have hsumS : Summable (fun m : \u2115 =>\n      \u2016LSeries.term (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n        (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I) m\u2016) := by\n    rw [summable_norm_iff]\n    exact ArithmeticFunction.LSeriesSummable_vonMangoldt hs1\n  have hle : \u2016LSeries (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n      (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I)\u2016 \u2264 dirichletCX n := by\n    show \u2016\u2211' m : \u2115, LSeries.term (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n      (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I) m\u2016 \u2264 _\n    calc \u2016\u2211' m : \u2115, LSeries.term (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n          (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I) m\u2016\n        \u2264 \u2211' m : \u2115, \u2016LSeries.term (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n            (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I) m\u2016 :=\n          norm_tsum_le_tsum_norm hsumS\n      _ \u2264 \u2211' m : \u2115, \u2016LSeries.term (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n            (((2 * Real.sqrt (n : \u211d)) : \u211d) : \u2102) m\u2016 :=\n          Summable.tsum_le_tsum (fun m => LSeries.norm_term_le_of_re_le_re _ (by\n            simp) m) hsumS hsumX\n      _ = dirichletCX n := rfl\n  calc \u2016logDeriv riemannZeta (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I)\u2016\n      = \u2016LSeries (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n          (((2 * Real.sqrt (n : \u211d)) : \u211d) + t * Complex.I)\u2016 := by\n        rw [\u2190 h1', norm_neg]\n    _ \u2264 dirichletCX n := hle\n\n/-- Termwise tail comparison: for m \u2265 3, the term at 2\u221an is \u2264\n3^{\u2212(2\u221an\u22122)}\u00b7(the term at 2). -/\nlemma norm_term_vonMangoldt_X_le_three_pow {n : \u2115} (hn : 1 \u2264 n) {m : \u2115} (hm : 3 \u2264 m) :\n    \u2016LSeries.term (fun n => (ArithmeticFunction.vonMangoldt n : \u2102))\n        (((2 * Real.sqrt (n : \u211d)) : \u211d) : \u2102) m\u2016 \u2264\n      (3 : \u211d) ^ (-(2 * Real.sqrt (n : \u211d) -
