Now I understand the D-056 theorem to formalize:
**Theorem R.** For s = σ + it, σ ∈ [−5/2, 3], |t| ≥ 10:
R(s) := ζ′/ζ(s) − Σ_{|γ−t|<1} 1/(s−ρ)
|R(s)| ≤ 10.5·log(|t|+2) + 48.
Wait — one important detail: D-056's R(s) has the near sum WITHOUT multiplicity weights: Σ_{|γ−t|<1} 1/(s−ρ). But the partial-fraction identity in Lean has Σ m_ρ(1/(s−ρ) + 1/ρ) over the zero subtype (with zeroMult). The D-036/D-056 paper convention writes the sum over zeros "counted with multiplicity" implicitly as Σ_ρ where each ρ appears m_ρ times, or without multiplicities if RH-simplicity... Actually in D-056, the near sum Σ_{|γ−t|<1} 1/(s−ρ) — since the R-bound is used in the contour assembly for the Li theorem, and zeros could have multiplicity in principle... In the paper world (D-036 §1), the sum runs over zeros counted with multiplicity (standard convention). In Lean, nearZeros t is a finset of the subtype with zeroMult weights — from LiDisc: `logDeriv_riemannZeta_sub_nearZeros_le`: ‖ζ′/ζ(s) − Σ_{|γ−t|<1} m/(s−ρ)‖ ≤ 100000·(log|t|)². So the near sum in the LiDisc capstone is mult-weighted: Σ_{ρ ∈ nearZeros t} (zeroMult ρ)/(s−ρ).
For 5f, the deliverable should be the tight version of the same shape:
‖logDeriv ζ s − Σ_{ρ ∈ nearZeros t} (zeroMult ρ : ℂ)/(s−ρ)‖ ≤ 10.5·log(|t|+2) + 48 for σ ∈ [−5/2, 3], |t| ≥ 10, ζ s ≠ 0 (and off the trivial zeros etc.).
Wait — but actually, hmm: what does the assembly (ii′-6) actually need? Let me check how D-037/D-062 use the R-bound. In D-037, the contour bounds for the Lagarias bridge use H = ζ′/ζ split into near sum + R-bound on the sides of the rectangle at height T(n) = √n+1... The R-bound enters the I_II/I_III estimates. The Lean marginTilde already encodes the CONSTANTS 10.5/48 via Hhat and the margin formula (see LiSkeleton: `2 * F T + 4 * T * ((2/3) * C0hat T + 10.5 * Real.log (T + 2) + 48) + ...`). So 5f's deliverable must produce exactly the bound shape used in D-037's assembly: the R-bound |ζ′/ζ(s) − Σ_near m/(s−ρ)| ≤ 10.5 log(|t|+2) + 48 for s on the contour (σ ∈ [−1,2]-ish, t = T ≥ ...).
Wait, in D-056 it's σ ∈ [−5/2, 3], |t| ≥ 10. The contour for ii′-6 (from D-037): the rectangle with corners... at height T = √n+1, σ from −(something) to 2. Anyway — σ ∈ [−5/2, 3] covers it (the contour's vertical range is within [−1, 2] per D-037? Hmm, actually the Lagarias kernel contour: from D-062's layer map, the sides are at re = −1/2...? I don't remember exactly. D-056 says σ ∈ [−5/2, 3] which should cover whatever the contour needs.)
Now — the Lean proof plan. From the partial-fraction identity:
logDeriv ζ s = B + seriesFun s − 1/s − 1/(s−1) + (log π)/2 − ψ(s/2)/2
Take the difference between s and s₀ = 2+it:
logDeriv ζ s − logDeriv ζ s₀ = seriesFun s − seriesFun s₀ − (1/s − 1/s₀) − (1/(s−1) − 1/(s₀−1)) − (ψ(s/2) − ψ(s₀/2))/2
(B cancels; (log π)/2 cancels.)
seriesFun s − seriesFun s₀ = Σ_ρ m_ρ [1/(s−ρ) + 1/ρ − 1/(s₀−ρ) − 1/ρ] = Σ_ρ m_ρ (1/(s−ρ) − 1/(s₀−ρ)) = Σ_ρ m_ρ (s₀−s)/((s−ρ)(s₀−ρ)).
So:
logDeriv ζ s = logDeriv ζ s₀ + Σ_ρ m_ρ(s₀−s)/((s−ρ)(s₀−ρ)) − (1/s − 1/s₀) − (1/(s−1) − 1/(s₀−1)) − (ψ(s/2) − ψ(s₀/2))/2.
Split the series into near (|γ−t| < 1) and far (|γ−t| ≥ 1):
Σ_near m_ρ(s₀−s)/((s−ρ)(s₀−ρ)) + Σ_far m_ρ(s₀−s)/((s−ρ)(s₀−ρ)).
R(s) = logDeriv ζ s − Σ_near m_ρ/(s−ρ). Note the near part of the difference series is Σ_near m_ρ[(s₀−s)/((s−ρ)(s₀−ρ))] = Σ_near m_ρ[1/(s−ρ) − 1/(s₀−ρ)]. So:
R(s) = logDeriv ζ s₀ − Σ_near m_ρ/(s₀−ρ) + Σ_far m_ρ(s₀−s)/((s−ρ)(s₀−ρ)) − (1/s − 1/s₀) − (1/(s−1) − 1/(s₀−1)) − (ψ(s/2) − ψ(s₀/2))/2.
This matches D-056's display (with multiplicities).
Six pieces:
1. |ζ′/ζ(s₀)| ≤ Z₂ ≤ 0.57 (Dirichlet bound at re 2 — in Lean: norm_logDeriv_zeta_le_dirichlet gives ≤ dirichletC2 — what is dirichletC2's value? It's defined in LiCircleBound line 203. If dirichletC2 ≤ 0.57 exactly... it's presumably defined as −ζ′/ζ(2) = Σ Λ(n)/n² ≈ 0.56996 or the majorant with some slack. Let me check the def.)
2. Near at s₀: |s₀−ρ| ≥ 1 (since re ρ ≤ 1... wait β < 1 strictly? For nontrivial zeros re ρ < 1 so |s₀−ρ| ≥ 2 − re ρ > 1. In Lean, IsNontrivialZero gives re < 1, so |s₀−ρ| ≥ |re(s₀−ρ)| = 2 − re ρ > 1 ≥ 1) ⟹ Σ_near m_ρ/|s₀−ρ| ≤ Σ_near m_ρ ≤ (count) ≤ C₀(t) — via the perimeter ZeroCountProp. In Lean: the count input is ZeroCountProp: ∀ t ≥ 2, (Nat.card (zeroWindow t) : ℝ) ≤ C0hat (t+1) where zeroWindow t = zeros with im in (t, t+1]? Need to check the exact def in LiContour.lean. The near sum Σ_{|γ−t|<1} m_ρ needs bounding by C0hat-ish via covering the window |γ−t| < 1 by two unit windows. In LiCircleBound there are Ncount bridges (Ncount_le_of_interval etc.) — mult-weighted counts. nearZeros_count_le (session 033): "the near-window mult-count ≤ 3·A₀·log(3·max|t−1||t+1|+5), single zerosIn window" — that's the unconditional Jensen-flavored count, NOT the perimeter one. For the TIGHT bound we need the perimeter version: Σ_near m ≤ 2·C0hat(t+2)-ish. Hmm, D-056 says ≤ C₀(t) where C₀(t) := F(t+1)−F(t) + S_b(t+1) + S_b(t) ≤ 0.433 log(t+2) + 0.886 loglog(t+2) + 2.9 = C0hat(t)... wait C0hat t = 0.433 log(t+2) + 0.886 log log(t+2) + 2.9 — and C₀(t) ≤ that. And Lean's ZeroCountProp: (Nat.card (zeroWindow t) : ℝ) ≤ C0hat (t+1). So the mult-count over |γ−t|<1 ⊂ (t−1, t+1) ⊂ two unit windows (t−1, t] and (t, t+1): each ≤ C0hat(t+1)... hmm: zeroWindow t covers (t, t+1]? Let me check the def. If zeroWindow t = {zeros with im ∈ (t, t+1]}, then |γ−t|<1 means γ ∈ (t−1, t+1) ⊂ (t−1, t] ∪ (t, t+1] = zeroWindow(t−1) ∪ zeroWindow(t). Each card ≤ C0hat(t) and C0hat(t+1) resp. (ZeroCountProp at t−1 gives ≤ C0hat(t); at t gives ≤ C0hat(t+1)). So Σ_near m ≤ C0hat(t) + C0hat(t+1) ≤ 2·C0hat(t+1)... but D-056 claims ≤ C₀(t) ≤ C0hat(t)!? Hmm — D-056's C₀(t) is DEFINED as the honest unit-interval count majorant F(t+1)−F(t) + S_b(t+1) + S_b(t), i.e., it ALREADY includes two window contributions (the F-difference plus two S_b slacks) — it's the count for the DOUBLE window (t, t+1] plus slacks, and |γ−t|<1 needs... hmm wait. Actually D-036's C₀(t) counts zeros in |γ−t| ≤ 1 (the unit-neighborhood count, not the unit-interval count). The Lean ZeroCountProp encodes C0hat (t+1) as the bound for zeroWindow t — what window exactly? Let me check LiContour.lean's zeroWindow def.
Whatever the exact form, the tight 5f needs the mult-count of nearZeros t ≤ something like 2·C0hat(t+2) and then the assembly constant folds as 13.73·(count bound) + 7.97 ≤ 10.5·log(|t|+2) + 48. The exact constant bookkeeping will need care: D-056's "C₀(t)" must map to the Lean-available count.
Hmm wait — actually, hold on. Is the ZeroCountProp's zeroWindow mult-weighted? "Nat.card (zeroWindow t)" — if zeroWindow is a SET of zeros (subtype), the card is NOT mult-weighted. But D-036's count F(t+1)−F(t)+S_b... counts WITH multiplicity (N(T) counts with multiplicity). For the near sum Σ m_ρ/(s₀−ρ) we need the mult-weighted count. If zeroWindow is a set (not multiset), Nat.card undercounts multiplicities. Hmm — but in LiCircleBound there are mult-weighted bridges from ZeroCountProp? The count bridges there were from Zeta23's RvM count (A0count, unconditional). Let me check: does LiContour/LiCircleBound have a mult-weighted window count from ZeroCountProp? `nearZeros_count_le` (session 033) is ≤ 3·A₀·log(...) — unconditional (A0count). For 5f we need the TIGHT count from ZeroCountProp — is there a mult-weighted version? Let me look at zeroWindow's definition and whether multiplicity matters.
Key question: is zeroWindow t a finset/set of zeros with Nat.card, and if so how does the mult-weight enter? In D-062 §4 the perimeter was declared as "Trudgian N(T)/S(T) in Ĉ₀ form" — the ZeroCountProp def: ∀ t ≥ 2, (Nat.card (zeroWindow t) : ℝ) ≤ C0hat (t+1). If zeroWindow is the SET of zeros (subtype elements) in the window, multiplicities are NOT counted. Then Σ_{ρ ∈ window} m_ρ could exceed card if some zero is multiple. BUT: zeroMult ρ ≥ 1, and Σ m_ρ = card only if all simple. Hmm — is there a multiplicity-vs-card bridge? In LiDisc there's the analyticOrderNatAt machinery (multiplicity = order). For the SET of zeros with multiplicities, Σ_{ρ ∈ S} m_ρ = Nat.card of the multiset...
Wait — actually, let me reconsider. Zeta23's zero_sum_inv_sq — is that mult-weighted? From ii′-1a: "Zeta23 zero_sum_inv_sq comparison" with the mult-weighted dominator (9/2)n²·mult/(1+‖γ‖²) — so liSummable handles mult via zero_sum_inv_sq which sums over the subtype with zeroMult weights? Let me check Zeta23's zero_sum_inv_sq statement — if it's Σ_ρ (mult ρ)/(1+γ²) < ∞ over the subtype, then... hmm.
For the tight count, maybe the cleanest: Σ_{ρ ∈ nearZeros t} zeroMult ρ ≤ C0hat-something requires a mult-weighted window count from the perimeter. If the perimeter only gives plain card bounds, we need a mult bridge: Σ m_ρ over a window ≤ mult-weighted count... The honest Trudgian N(T) DOES count with multiplicity, so the intended perimeter semantic is mult-weighted. Let me check the actual zeroWindow definition in LiContour.lean — maybe zeroWindow t is defined as a multiset or with multiplicity baked in. Let me read.
Also need to see how the D-062 perimeter was declared in the paper: "Trudgian N(T)/S(T)" — N(T) counts with multiplicity. Let me read LiContour.lean's ZeroCountProp region.
Also piece 3 (far difference) needs the two-sided interval counts with multiplicity — D-056's grouping by unit intervals uses C₀(t) (the mult-weighted unit-neighborhood count) for the left side (k intervals below t), C₀(2t) for the right side, and the k > t tail. In Lean this becomes a sum over dyadic/unit intervals of the mult-weighted count — again needs the mult-weighted window count from ZeroCountProp.
So the CRITICAL first question: what mult-weighted count machinery exists from ZeroCountProp? Let me look at LiContour.lean (zeroWindow def) and LiCircleBound.lean's count bridges (A0count was the unconditional one; is there a ZeroCountProp-fed bridge? gapCircle construction used ZeroCountProp via zeroWindow_finite + C0hat — the exists_gapCircle_radius proof used "the perimeter ZeroCountProp on the two unit windows" per D-068 §2. Let me read LiGapCircles to see how the count was used — that shows the available bridge.
Let me read:
1. LiContour.lean ZeroCountProp + zeroWindow definitions.
2. LiGapCircles.lean exists_gapCircle_radius's use of ZeroCountProp (how card → C0hat was applied).
3. LiCircleBound's nearZeros def + nearZeros_count_le.
4. dirichletC2 def (piece 1 constant).
D-056 read. Now the Lean-side count machinery — critical question: how `ZeroCountProp` feeds mult-weighted window counts. Checking LiContour (ZeroCountProp/zeroWindow defs), LiGapCircles (how the perimeter count is consumed), and LiCircleBound (nearZeros + dirichletC2).
