The cumulative form of the headline result, again with no hypotheses. Here N(0,T)N(0, T) (Ncount 0 T) counts the nontrivial zeros ρ\rho of Mathlib's riemannZeta (ζ(ρ)=0\zeta(\rho) = 0, 0<Re⁡ρ<10 < \operatorname{Re}\rho < 1) with 0<Im⁡ρ≤T0 < \operatorname{Im}\rho \le T, counted with multiplicity, and N0∗(0,T)N_0^*(0, T) (N0star 0 T) counts the distinct such zeros on the critical line Re⁡ρ=1/2\operatorname{Re}\rho = 1/2.

The assertion: for every ε>0\varepsilon > 0 there exists T0T_0 such that for all T≥T0T \ge T_0,

(23−ε) N(0,T)  ≤  N0∗(0,T),\Big(\frac{2}{3} - \varepsilon\Big)\, N(0, T) \;\le\; N_0^*(0, T),

which is the ε\varepsilon-form of lim inf⁡T→∞N0∗(T)/N(T)≥2/3\liminf_{T \to \infty} N_0^*(T)/N(T) \ge 2/3 for the classical cumulative counting functions N(T):=N(0,T)N(T) := N(0,T), N0∗(T):=N0∗(0,T)N_0^*(T) := N_0^*(0,T).

In Zeta23.Final it follows from the single-hypothesis cumulative version by discharging the explicit formula (proved as WeilEF.EF_lit_zetaZeroConfig); the passage from dyadic windows (T,2T](T, 2T] to (0,T](0, T] uses the Riemann–von Mangoldt zero-counting development. It is a terminal node of the project.
