D-056's original far sum: uses |s₀−ρ| ≥ (1+x)/√2, giving per-term ≤ 4.5√2/(x(1+x)) ≤ 4.5√2/(k(k+1)), and Σ 1/(k(k+1)) = 1. Tail (k > t): ≤ C₀(2t)/(t+1) + 0.433/t ≤ 0.53. Total 4.5√2·[2C₀ + 0.58 + 0.53] = 12.73·C₀ + 7.06. But journal-035's session-035 REVISED plan uses the sharper per-term |s₀−ρ| ≥ √(1+x²), giving per-term ≤ 4.5/(x√(1+x²)) ≤ 4.5/(k√(1+k²)), S₃ = Σ 1/(k√(1+k²)) ≤ 1.3703, and the total 4.5·[2·S₃·C₀ + 0.55·S₃ + 0.5828] = 12.333·C₀ + 6.014. The k > t tail ≤ 0.5828: this is 4.5·[tail]. So [tail] = 0.1295. The tail = Σ over zeros with x > t of 1/(x√(1+x²))... bounded via per-interval counts C0hat(t+k+1) ≤ ... hmm we computed that gives ~1.24·(1/4.5)... wait no: 4.5·[tail] where tail = Σ_{k>t} count_k/(k√(1+k²)). If count_k ≤ C0hat(t+k+1) ≤ 0.433·log(t+k+3) + 0.886·log log + 2.9, for k > t ≥ 10: log(t+k+3) ≤ log(2k+3). Hmm, let me numerically estimate Σ_{k≥11} (0.433·log(2k+3) + 0.886·log log(2k+3) + 2.9)/(k√(1+k²)): - 2.9·Σ_{k≥11} 1/k² ≈ 2.9·0.0952 ≈ 0.276 - 0.433·Σ log(2k+3)/k² ≈ 0.433·(log 25/11 + log 27/12 + ∫₁₁^∞ log(2x+3)/x² dx). ∫ log(2x+3)/x² dx from 11: = [−(log(2x+3)+2)/x]₁₁^∞ + ... roughly (log 25 + 2)/11 ≈ 0.474. Plus boundary terms ≈ 0.29+0.23. Total ≈ 0.474+0.2 ≈ maybe 0.8. Times 0.433 ≈ 0.35. - loglog part ≈ 0.886·0.2 ≈ 0.18. Total ≈ 0.8. Times 4.5 ≈ 3.6. Way more than 0.5828. So the tail ≤ 0.5828 must use something else. "Σ log(3k)/k² and Σ 1/k² via the same telescopes". Hmm — 0.5828 = 4.5·0.1295. Σ_{k≥11} log(3k)/k² ≈ log 33/11 + log 36/12 + ∫₁₁^∞ log(3x)/x² = 0.317+0.298+ (log 33+1)/11 ≈ 0.317+0.298+0.408 ≈ 1.02. Times something... A₀? Hmm, wait — maybe the tail count uses the fact that these zeros are at height ≥ 2t ≥ 20... no. Let me reconsider: maybe the tail is bounded NOT via counts but via the global weighted sum `zero_tail_inv_sq_le` (LiCircleBound line 745): Σ_{|γ|>X} m/(1+γ²) ≤ 16·A₀·log X/X for X ≥ 200. For the tail zeros (x = |t−γ| > t, so |γ| ≥ ...): hmm, γ > 2t or γ < 0 (with |γ| ≥ 14). For γ < 0, |γ| = x − t; for γ > 2t, |γ| = x + t > t. For a tail zero, 1/(x√(1+x²)) ≤ 1/x². And x = |t−γ| relates to |γ|: x ≤ t + |γ| ≤ 2|γ| when |γ| ≥ t... For γ > 2t: x = γ−t ≥ γ/2 = |γ|/2. For γ < 0: x = t+|γ| ≥ |γ|. So x ≥ |γ|/2 in both cases (for γ > 2t or γ < 0). So 1/x² ≤ 4/|γ|² ≤ 4/(1+γ²)·(1+γ²)/γ² ≤ 4·2/(1+γ²) (since γ² ≥ 196, (1+γ²)/γ² ≤ 2). So Σ_tail m/(x√(1+x²)) ≤ Σ_tail m/x² ≤ 8·Σ_{|γ|>t, tail} m/(1+γ²)... hmm wait but |γ| for tail zeros: γ > 2t or γ < 0 with |γ| ≥ 14. If t ≥ 200, we could apply zero_tail_inv_sq_le with X = t... but t ∈ [10, 200) isn't covered, and the bound 16·A₀·log(t)/t with A₀ ≥ 1 at t=10: 16·2.3/10 = 3.7. Too big. Hmm, this isn't leading anywhere productive. The "0.5828" figure — let me just compute what combination gives 0.5828: "the k > t tail ≤ 0.5828 (Σ log(3k)/k² and Σ 1/k² via the same telescopes)" Maybe: tail ≤ 4.5·A₀·[Σ_{k>t} 3·log(3k)/k²]-ish? With A₀'s ACTUAL value (not the ≥ 1 bound). Let me find the actual value of the RvM constant in Zeta23. Let me grep the Zeta23 repo.
Let me find the actual RvM local count statement in Zeta23 to know A0count's concrete value.
