CRITICAL FINDING: the honest total **exceeds** Bn for n ≳ 5×10⁷ (ratio 1.012 at 10¹², 1.015 at 9×10²⁴). The slack at 10⁵ is 117k but it SHRINKS and goes negative around n ≈ 5×10⁷. So my honest pieces are worse than Bn asymptotically. Why? Let me diagnose which piece overshoots asymptotically. Compare growth rates: - Bn's I_III term: 4T·[(2/3)Ĉ₀ + 10.5 log + 48] ~ 4T·(10.5)·log T (leading, since (2/3)Ĉ₀ ~ 0.29 log T). - Honest I_III: 4T·[(2/3)Z2 + 10.5 log + 48]: Z2 ~ 0.6 log T vs Ĉ₀ ~ 0.433 log T: (2/3)·0.6 = 0.4 vs (2/3)·0.433 = 0.289: honest leading = 4T·(0.4 + 10.5)·log T vs baked 4T·(0.289+10.5)·log T: honest exceeds by 4T·0.111·log T — the I_III two-unit correction grows like T·log T and eventually eats the slack! - Bridge: honest 4F vs baked 2F: +2F ~ +0.318·T·log T — ALSO grows like T log T! - Horizontals: honest NI ~ Z2·2·log(148.5·C0hat) ~ 0.6L·2·log(148.5·0.433L) ~ 1.2L·log L vs baked 7Ĥ ~ 21·(0.433L)² = 3.94L²: the horizontal fit IMPROVES asymptotically (NI/(7Ĥ) → 0) ✓ (the ratio column: 0.398 → 0.241 decreasing ✓). So the killers are the I_III two-unit correction (+4T·(0.111)·log T) and the bridge factor-2 (+2F ~ 0.318·T·log T): total extra ≈ 4T·0.111·log T + 0.318·T·log T ≈ (0.444+0.318)·T·log T ≈ 0.762·T·log T vs the horizontal slack (baked − honest) ≈ 2(e⁴+1)·(7Ĥ − NI−5.5·(10.5 log+48)) ~ 2(e⁴+1)·(3.94L² − 1.2L·log L − 5.5·10.5L) ~ 110·3.94L² ≈ 433·L². The slack grows like L² = (log T)² while the excess grows like T·log T — T = √n beats (log T)² eventually ⟹ crossover ~ 5×10⁷. CONFIRMED by the table. So the honest pieces as I wrote them DON'T fit. Need to fix the two killers: **Fix 1 (I_III)**: the (2/3)·Z2 near-sum on the left vertical. The baked (2/3)Ĉ₀ charges the near-sum (|w−ρ| ≥ 3/2, count ≤ Ĉ₀). Honest count: two-unit Z2. But wait — the tight R-bound's near set (nearZeros t in the 5f capstone — the UNIT window [t-1, t+1]?) — 5f's capstone already charges the near sum with the TWO-UNIT count (D-069 Finding 1's fix is INSIDE the tight R-bound's 10.5·log+48). Wait no — the tight R-bound is ‖ζ′/ζ(s) − Σ_{near} m/(s−ρ)‖ ≤ 10.5·log+48 — the near sum Σ_{near} m/(s−ρ) is OUTSIDE the bound; it's charged separately by the CONSUMER. For the left vertical: Σ_{near} m/|w−ρ| ≤ (2/3)·(near count). The near count (nearZeros t = unit window? nearZerosSub — the subtype version) — what's its definition? From 5f: "near ≤ P1-count ≤ 0.6·L + 0.886·LL + 2.7 (|s₀−ρ| ≥ 1 since re ρ ≤ 1)" — the two-unit count Z2! So 5f's own near-sum charging uses Z2. The near sum is a TWO-unit window sum — its honest count is Z2 = 0.6L+0.886LL+2.7 — and Bn's baked (2/3)Ĉ₀ with Ĉ₀ = 0.433L+0.886LL+2.9 is SMALLER. So the I_III (2/3)Ĉ₀ term in Bn genuinely undercounts the near-sum on the left vertical — D-069 Finding 2 said exactly this: "D-037's I_III (2/3)·Ĉ₀ coefficient gets the analogous two-unit correction to (4/3)-ish". Hmm — wait, "(4/3)-ish": (2/3)·Z2 ≈ (2/3)·(0.6/0.433)·Ĉ₀ ≈ (2/3)·1.386·Ĉ₀ ≈ 0.92·Ĉ₀ ≈ (4/3)·(2/3)Ĉ₀·... the (4/3) means the COEFFICIENT of Ĉ₀ goes from 2/3 to ~4/3?? (2/3)·Z2 with Z2 ≈ 1.4Ĉ₀ gives ≈ 0.93Ĉ₀ — that's a (2/3)→~0.93Ĉ₀ correction, i.e. coefficient of T·Ĉ₀ in 4T[...]: from 4·(2/3) = 2.67 to 4·0.93 = 3.7 — the "(4/3)-ish" must mean 4·(1/3)... whatever. The excess over baked: 4T·[(2/3)(Z2−Ĉ₀)] = 4T·(2/3)·[(0.6−0.433)L + (2.7−2.9)] = 4T·(2/3)·[0.167L − 0.2] ≈ 4T·0.111·L. Can this be avoided? YES — charge the near-sum on the left vertical more cleverly: the near-sum Σ m/|w−ρ| with |w−ρ| ≥ 3/2... the zeros are at distance ≥ 3/2 from the ENTIRE vertical line — but most near-window zeros are much farther: |w−ρ|² = (5/2−β)² + (t−γ)². Split the near window: zeros with |t−γ| ≥ 1 are in the R-part already. The near window |t−γ| < 1: |w−ρ| ≥ 3/2 exactly. Hmm — the (2/3) is tight for zeros with β → 1, γ → t. So the near-sum honestly needs the two-unit count × (2/3). UNLESS we bound the near-sum by the UNIT-window count on each of the two halves [t−1, t] and [t, t+1]: each ≤ Ĉ₀: total ≤ 2Ĉ₀ — worse than Z2 (Z2 ≈ 1.39Ĉ₀). So Z2 is the honest charge: I_III honest = 4T·[(2/3)Z2 + 10.5 log + 48] — EXCEEDS baked by 4T·(2/3)(Z2−Ĉ₀) ≈ 0.444·T·L — grows like T·L. KILLER confirmed. Hmm — so how does the paper's B(n) survive?? The baked I_III uses (2/3)Ĉ₀ — undercounted per Finding 2. The Finding-2 doc says "E-028's 26× slack says the theorem survives; the certified crossover artifacts move". The THEOREM (λ_n > 0) survives because |Sf| is tiny; but SfBoundProp (|Sf| ≤ Bn baked) — the honest assembly does NOT prove it for large n. Wait — unless the OTHER pieces' slack absorbs: the horizontals' slack grows like 433·L² ≈ 433·(log T)² — the killers grow like T·log T = √n·(0.5 log n) — at n = 9×10²⁴: T = 3×10¹², killers ≈ 0.762·3×10¹²·29 ≈ 6.6×10¹³; horizontal slack ≈ 433·841 ≈ 364,000. Utterly outgunned. What else has slack? The bridge 2F baked... I_I: negligible. 40M₀: constant. Hmm. **Rethink the bridge**: |λ_n(T)| ≤ 2·(both-signs mult count). Both-signs count = 2·N_classical(T) ≤ 2·FAlt(T)?? — is N_classical ≤ FAlt?? FAlt's comment: "any literature bound N(T) ≤ F(T) + S_b(T) upgrades to N(T) ≤ FAlt(T)" — yes N_classical ≤ FAlt. So both-signs ≤ 2·FAlt, bridge ≤ 4·FAlt. Baked: 2·FAlt. Killer +2·FAlt ~ 0.318·T·log T. Hmm — wait: is the bridge's per-term bound really 2? |1 − (ρ/(ρ−1))ⁿ| ≤ 1 + |ρ/(ρ−1)|ⁿ = 2 on the line. BUT — a better bound for most zeros: for |γ| LARGE vs n... no, γ ≤ T ≈ √n and n ≥ 10⁵: nθ with θ = arg(ρ/(ρ−1)): ρ = 1/2+iγ: ρ/(ρ−1) = (1/2+iγ)/(−1/2+iγ): |w| = 1, arg ≈ π − 2·arctan(1/(2γ))·... ≈ π − 1/γ·...: w ≈ e^{i(π−1/γ)}: wⁿ ≈ e^{inπ − in/γ}: |1−wⁿ| can be up to 2. No uniform improvement. The honest bridge is 4·FAlt. BUT WAIT — maybe pair the terms! λ_n(T) = Σ mult·(1−(ρ/(ρ−1))ⁿ) over both signs. Pair ρ, ρ̄: (1−wⁿ) + (1−w̄ⁿ) where w̄ = conj(w)... on the line w̄ = w⁻¹: pair = 2 − (wⁿ + w⁻ⁿ) = 2 − 2cos(nθ) ≤ 4 = 2+2 per pair — same as 2 each. No gain. Alternatively — maybe charge the bridge with multiplicity... same. Hmm OK — so both killers are real and grow like T·log T. The fold as I've designed it FAILS for n ≳ 5×10⁷. But wait — how did the PAPER's assembly (D-037/E-028) pass? The paper's |Sf| ≤ B(n) is only used through the MARGIN: margin = S_∞^lower − B + 1 > 0 on [N₀, N₁]. If the honest B_honest exceeds Bn beyond 5×10⁷, then the paper's B(n) itself is an UNDERCOUNT of the honest assembly beyond 5×10⁷ — meaning the paper's bound |Sf(n)| ≤ B(n) is NOT what the assembly proves there... BUT the theorem only needs margin > 0: margin_honest = S − B_honest + 1 — the killers add ≈ 0.762·T·log T ≈ 6.6×10¹³ at N₁ to B — while margin(N₁) = 2.458×10²⁶. So the THEOREM survives trivially. The issue is only the LEAN SfBoundProp which must match the BAKED Bn exactly (because lambda_pos_finite_height_verified consumes it). Resolution options: (A) **Change SfBoundProp's Bn** to the honest form (edit LiSkeleton's Bn definition: bridge 2F → 4F... wait no — Bn's 2F term: baked is 2·FAlt. Honest bridge 4·FAlt. And I_III (2/3)Ĉ₀ → (2/3)Z2. Then margiñ machinery (marginTilde := sInftyLower − Bn + 1, the convexity proof, the base points) still works? marginTilde_convex is PROVED for the Bn-with-F-parameter... Bn F n uses F := FAlt parameter for the 2F term only; the rest is fixed. Changing Bn's definition changes marginTilde — the convexity proof (marginTilde_convex, D-057's ψ-table) is structural (each block's ψ < 0 — the I_III block (2/3)Z2 vs (2/3)Ĉ₀: Z2's ψ... the convexity proof would need re-verification for the changed blocks; the base points (margiñ(8×10⁴) ≥ 8001, margiñ(10⁵) ≥ 85 501) would DROP by the honest excess at those n (≈ 117k − 118k... wait at n=10⁵ honest < baked by 117k so margin INCREASES?? No wait — honest at 10⁵ is SMALLER (ratio 0.656) because the horizontal slack dominates there. So with honest pieces, B_honest(10⁵) = 224k < Bn(10⁵) = 342k — margin(10⁵) INCREASES by 118k! And at 8×10⁴ similar. So changing Bn to the honest form IMPROVES the base points and only requires re-checking the crossover region: the honest B is smaller near 10⁵, larger beyond 5×10⁷ — but margin > 0 throughout [N₀, N₁] regardless (the excess is ≪ margin). The convexity re-verification is structural (the changed blocks: 4F vs 2F — same F block ×2, ψ scales ×2 still negative; I_III (2/3)Z2: Z2 = 0.6L+0.886LL+2.7 — similar form to Ĉ₀ = 0.433L+0.886LL+2.9 — the ψ-table rows cover log/loglog forms ✓ structural re-verify, D-057's machinery applies). But (A) edits LiSkeleton.lean (Bn def) — VIOLATES the freeze protocol? The freeze says: "no edits to existing Lean proofs except the liCoeff correctness fix (ii′-1a)". Editing Bn's definition would break downstream proofs (marginTilde_convex, base points, lambda_pos_finite_height_verified) — they'd need re-verification but the STATEMENTS (SfBoundProp, the theorem) would then be about the honest Bn. Hmm — but SfBoundProp is the hypothesis consumed by lambda_pos_finite_height_verified; if I change Bn, SfBoundProp changes meaning, and the theorem's statement... lambda_pos_finite_height_verified : ∀ n, 1 ≤ n → (n:ℝ) ≤ (3×10¹²−1)² → 0 < (liCoeff n).re — the FINAL statement is Bn-independent! The margin machinery is internal. So changing Bn internally is SAFE for the final statement: lambda_pos_finite_height_verified would still prove 0 < (liCoeff n).re from (hRH)(hfinite)(hSf) with hSf : SfBoundProp (redefined with honest Bn). And ii′-7's sfBoundProp : SfBoundProp would prove the honest version. The perimeter is unchanged. BUT the freeze protocol (user directive 2026-08-21): "no edits to existing Lean proofs except the liCoeff correctness fix (ii′-1a)". Editing Bn violates this — needs user approval. AND it invalidates the proved marginTilde_convex + base points (re-verification needed — structural, but real work: the ψ-table for the changed blocks + re-certified base points). (B) **Keep Bn; prove the honest pieces fit under Bn on [10⁵, N₁]** — IMPOSSIBLE per the numerics (honest > baked beyond 5×10⁷). UNLESS the honest pieces are sharpened: the killers are (i) bridge 2F extra, (ii) I_III two-unit extra. Can either be sharpened to fit under baked? (i) Bridge: the honest bridge is 4·FAlt. Could a sharper analysis give 2·FAlt? |λ_n(T)| = |Σ mult·(1−w_ρⁿ)| — the actual truncated sum. Hmm — the terms 1−wⁿ with |w| = 1: no cancellation provable in general (extremal: all wⁿ ≈ −1). So no: 4·FAlt is the honest worst case. The baked 2F is an undercount (the D-036/D-037 factor-2 slip). (ii) I_III: (2/3)Z2 vs (2/3)Ĉ₀: Z2 is the honest two-unit count. Could charge the near-sum as ≤ (2/3)·N(t+1)−N(t−1) with the GLOBAL count difference ≤ FAlt-difference + 2·S_b-parts... the global N(t+1)−N(t−1) ≤ F(t+1)−F(t−1) + 2·S_b(max) ≈ (1/π)log(t·...)·2... ≈ 0.318·log T + const — vs Ĉ₀ = 0.433L+0.886LL+2.9: the global difference (F(t+1)−F(t−1) + S_b(t+1)+S_b(t−1)) ≈ (2/2π)(log T + 1) + 2·(0.137L + 0.443LL + 1.588) = 0.318L + 0.274L + 0.886LL + 3.18 = 0.592L + 0.886LL + 3.18 vs Z2 = 0.6L+0.886LL+2.7 — nearly identical (0.592 vs 0.6). And vs Ĉ₀ = 0.433L+...: still the +0.16L excess. So no sharpening there — the two-unit excess is intrinsic. So (B) is out: the baked Bn undercounts the honest assembly for n ≳ 5×10⁷. The baked SfBoundProp is still TRUE (|Sf| is tiny) but NOT PROVABLE via the contour assembly as baked. (C) **Narrow SfBoundProp's range**: SfBoundProp is consumed with n ∈ [10⁵, N₁]. What if the Lean assembly proves |Sf n| ≤ B_honest(n) and we ALSO prove B_honest(n) ≤ Bn(n) on a range where it holds — the numerics say it holds for n ≤ ~5×10⁷. For n > 5×10⁷... the margin proof needs |Sf| ≤ Bn for margin > 0 — but wait, for large n we could use a DIFFERENT bound: is there an alternative? Hmm no. (D) **Change the C0hat/Hhat constants inside Bn to honest forms** — same as (A) but more surgical: Bn's I_III block: 4T·[(2/3)Ĉ₀ + ...] → 4T·[(2/3)Z2 + ...]; bridge 2F → 4F. This is (A). So (A) is the route: redefine Bn with the honest constants (bridge 4F, I_III (2/3)Z2), re-verify marginTilde_convex structurally + re-certify the base points (they IMPROVE since honest < baked near 10⁵). And SfBoundProp becomes the honest-Bn version — provable on [10⁵, N₁] (honest ≤ honest trivially; the fit issue disappears because SfBoundProp's Bn IS the honest bound). Wait — but then does margin > 0 still hold on [N₀, N₁]? margin = S − B_honest + 1: at n = 10⁵: S ≈ 433,000... wait let me recompute: sInftyLower(10⁵) = ½·10⁵·log(10⁵) + (C₁−γ/2)·10⁵ − 4 = ½·10⁵·11.513 − 1.41894·10⁵ − 4 = 575,650−141,894−4 = 433,752. B_honest(10⁵) = 224,000. margin = 209,000 > 0 ✓ (BIGGER than the baked margin 93k!). At N₁: excess over baked ≈ 6.6×10¹³ ≪ margin(N₁) ≈ 2.46×10²⁶ ✓. The crossover: honest B is smaller near 10⁵, larger beyond ~5×10⁷ — the crossover n where margin becomes positive: with smaller B near 10⁵ the crossover moves DOWN (better). ✓ All good — margin > 0 on [N₀, N₁] trivially survives (the excess at N₁ is 10⁻¹³ relative). The cost of (A): edit LiSkeleton.lean's Bn (+ marginTilde machinery is F-parameterized — Bn F n has F only in the 2F term: changing to 4F means Bn's F-term doubles: Bn F n = 4·F T + ...? Hmm — actually wait: is the honest bridge 4·FAlt or 2·(both-signs count) with both-signs ≤ 2·FAlt? FAlt majorizes the ONE-sign N(T). The Lean bridge: |λ_n(T)| ≤ 2·(Σ_{both} mult) ≤ 2·(2·FAlt T) = 4·FAlt T. So Bn's 2F term → 4F term. And the I_III (2/3)Ĉ₀ → (2/3)Z2. These edits touch: - Bn def (LiSkeleton:2413). - marginTilde_eq_sub + the mK-style constants? (LiSkeleton:1819 mK has −40·1.3352 etc. — used in convexity). - marginTilde_convex (session 011 proof — the ψ-table: the F-block ×2 and the I_III block changed → re-verify those rows; structural but must be redone). - The base points LiBasePoints (margiñ(8×10⁴) ≥ 8001, margiñ(10⁵) ≥ 85 501 — with honest B SMALLER at those points, the certified bounds still hold... wait: honest B(10⁵) = 224k < baked 342k ⟹ margiñ(10⁵) = S − B_honest + 1 = BIGGER ⟹ the certified lower bounds (≥ 8001, ≥ 85 501) remain TRUE but the certified values are now loose — actually the certified computations must be REDONE because Bn's definition changed (the proof of marginTilde_FAlt_80000_pos computes the value from Bn's definition — changing the def changes the value — the certified bound ≥ 8001 would still hold since the new value is bigger, but the PROOF term evaluates the old def — broken proofs need re-verification). This is real work but bounded: the convexity rows for the changed blocks + the two base-point certificates. It VIOLATES the freeze protocol (edits existing proofs) — needs explicit user approval. (E) **Alternative: leave Bn frozen; make SfBoundProp's statement use Bn but prove it via a DIFFERENT argument for the excess pieces** — e.g., prove |Sf n| ≤ B_honest(n) AND B_honest(n) ≤ Bn(n) on [10⁵, N₁]?? — numerics say FALSE beyond 5×10⁷. Out. (F) **Leave Bn frozen; prove |λ_n(T)| ≤ 2·FAlt via a SMARTER bridge**: pair-conjugate accounting! λ_n(T) = Σ_{both} mult·(1−w_ρⁿ): group conjugate pairs: Σ_{γ>0} mult·[(1−wⁿ)+(1−w̄ⁿ)] = Σ_{γ>0} mult·(2−2Re wⁿ) — the pair sum ≤ 4 per pair (mult·... wait mult per zero; pair = mult·(2 − wⁿ − w̄ⁿ) = mult·(2−2Re wⁿ) ≤ 4·mult = 2·(2·mult) — the pair contributes ≤ 4·mult, i.e. 2·mult per zero — same as before. |λ_n(T)| ≤ Σ_{γ>0} 4·mult = 4·N_classical ≤ 4·FAlt. SAME. No improvement — because |2−2Re wⁿ| ≤ 4 is tight. So (A) is the route. The paper's B(n) has the factor-2 bridge slip + the I_III two-unit slip — BOTH must be corrected in the paper too (erratum list for ii′-7's paper update: D-037 line-63 erratum pointer already planned — add these). And E-028's margin computations used the baked (undercounted) B(n) — the theorem survives because the corrections are ≪ margins (verified numerically above: at 10⁵ honest < baked; the crossover region is FINE because honest B near 8×10⁴–10⁵ is SMALLER than baked — the crossover moves DOWN if anything; and at N₁ the excess is 10⁻¹³ relative). Wait — careful: the paper's margin(N₀) at N₀ = 8×10⁴ uses baked B — with honest B SMALLER there, margin(8×10⁴) is BIGGER — crossover still ≤ 75,451 ✓. And margiñ' > 0 direction: honest B grows slightly faster (extra T·log T terms) — margin' = S' − B' — at N₀, S' ≈ ½(log n + 1) − ... vs B' — the margin-derivative sign near the crossover needs a re-check but with margin(8×10⁴) = 15,764 + honest-slack(≈ 117k at 10⁵, ≈ 110k at 8×10⁴?) — the margin at 8×10⁴ with honest B ≈ 15,764 + (342k−224k scaled) — bigger — and the convexity argument (structural) re-verifies. Fine. OK so the design decision (A) is clear: **redefine Bn honestly** (bridge 4F, I_III (2/3)Z2), keep SfBoundProp's RANGE [10⁵, N₁], re-verify margin convexity structurally + re-certify base points (they improve), fix the paper at ii′-7 (errata: D-036 §4 + D-037 (4.1) factor-2 bridge + I_III two-unit count — the theorem R-004 unaffected). Hmm wait — actually, hold on. Let me reconsider once more. Is there a way to keep Bn untouched AND make the fold work? The killers: bridge +2F, I_III +4T·(2/3)(Z2−Ĉ₀). Total extra at N₁ ≈ 6.6×10¹³ ≈ 1.5% of Bn(N₁) = 4.37×10¹⁵. What if instead of the horizontals' segment-integral (which I used to CREATE slack), I check: does the baked horizontals 2(e⁴+1)[7Ĥ+3.3] cover the honest horizontals with Finding-2's honest-MAX (7Ĉ₀²+8Ĉ₀+A log+B₀)? Honest-max horizontal inside: 7·(7Ĉ₀²+8Ĉ₀+10.5 log+48)+3.3 vs baked 7·(3Ĉ₀²+10.5 log+48)+3.3: honest-max exceeds by 7·(4Ĉ₀²+8Ĉ₀) ≈ 28Ĉ₀² ≈ 28·(0.433L)² ≈ 5.25·L² — ×2(e⁴+1) ≈ 110: ≈ 578·L² — grows like L², same order as the baked Ĥ's L²... at N₁: 578·841 ≈ 486k — trivial vs the T·log T killers. So the horizontal near-sum form (max vs integral) is IRRELEVANT to the killers. The killers are intrinsic (bridge factor 2 + I_III two-unit count). No fold trick avoids them. (A) is forced. Hmm, wait — actually one more: could the bridge avoid the both-signs count by choosing the rectangle to only enclose the UPPER zeros? The rectangle is [−T, T] in im — symmetric. Could we use a rectangle [0, T]×im? The residue theorem needs a closed contour around 1 and the zeros... Lagarias's contour is symmetric because Jlag's poles include ALL zeros (both signs) inside. A half-rectangle [−5/2, 2√n]×[0, T] would enclose only upper zeros — but then the bottom side is the REAL segment [−5/2, 2√n] crossing 1 (the pole!) and trivial zeros — no good. The symmetric contour is required. So both-signs count is intrinsic. (A) forced. Hmm, OR: pair the conjugate terms BEFORE bounding: λ_n(T) = Σ_{γ>0} mult·(2 − 2Re(w_ρⁿ)) — |2−2Re wⁿ| ≤ 4 — the SAME 4·mult per pair. |λ_n(T)| ≤ 4·N_classical. Same. OK. Hmm hmm — wait, one more idea for the bridge: 2 − 2Re wⁿ with w = ρ/(ρ−1), ρ = 1/2+iγ: w = e^{iθ} with θ = π − 2 arctan(1/(2γ))·... θ ≈ π − 1/γ for large γ. wⁿ ≈ e^{inθ}: 2−2cos(nθ). For this to be near 4 need nθ ≈ π mod 2π: n(π − 1/γ) ≈ π: n − n/(γπ) ≈ 1 mod 2 — possible for some (n, γ). No uniform improvement. OK truly (A). Wait, actually, hold on — let me reconsider the bridge once more. |λ_n(T)| ≤ 2·Σ mult where Σ is the both-signs mult-count. Both-signs mult-count = 2·N_classical (if all mult = 1) — but mult can be > 1 (we don't have simplicity!). mult-weighted both-signs = 2·(mult-weighted one-sign) ≤ 2·FAlt — hmm wait: does the mult-weighting change anything? FAlt majorizes the mult-weighted one-sign count (Trudgian's N(T) counts zeros WITHOUT multiplicity classically! N(T) = #zeros — Trudgian's bound is on the count of zeros (distinct), not mult-weighted!). Hmm — but mult > 1 would make the mult-weighted count bigger than N(T). Does Trudgian's bound cover mult-weighted? N(T) with multiplicity = N(T) without (the count is the same sum with mult — standard: N(T) counts with multiplicity). Actually the classical N(T) counts WITH multiplicity (it's the winding number). And F(T)+S(T) bounds it. So mult-weighted one-sign ≤ FAlt ✓ consistent with ZeroCountProp being mult-weighted ✓. OK. Decision (A) confirmed. But it requires editing LiSkeleton.lean (Bn def + downstream re-verification) — a freeze-protocol exception requiring USER APPROVAL. Also the two perimeter formalizations (ZeroCountGlobalProp, MZeroProp) — approval as well (they're within the already-approved trust classes). Given the stakes, I should present this to the user NOW — the design review with the two findings (bridge factor-2 slip in the paper; I_III two-unit slip) and the required decisions: 1. Approve Bn redefinition (freeze exception) — honest constants: bridge 4F, I_III (2/3)Z2 — with re-verified convexity + base points (they IMPROVE: honest B < baked B near 10⁵). 2. Approve the two perimeter formalizations (ZeroCountGlobalProp global Trudgian N(T) ≤ FAlt; MZeroProp M₀ ≤ 1.3352) — same trust classes as already approved. 3. Note for the paper erratum list (ii′-7): D-036 §4/D-037 (4.1) bridge factor-2 + I_III two-unit count slips; theorem R-004 unaffected (corrections ≪ margins, verified numerically). Hmm — wait, actually, before going to the user, let me double-check the factor-2 bridge claim once more by looking at how E-023/E-028 actually computed the zero-sum bound... Let me check E-023's assembly code — what did they use for 2N(T)?
**Critical design finding** — validated numerically: the honest pieces **exceed** the baked Bn beyond n ≈ 5×10⁷ (ratio 1.012 at 10¹²). Two intrinsic killers, both growing like T·log T: 1. **Bridge factor-2**: λ_n(T) sums over *both signs* of γ ⟹ |λ_n(T)| ≤ 4·FAlt honestly, but Bn charges 2·FAlt — a factor-2 accounting slip in D-036/D-037 (harmless to R-004: the correction is ≪ margin everywhere). 2. **I_III two-unit count** (D-069 Finding 2's predicted (4/3)-ish correction). Verifying the factor-2 claim against the actual E-023/E-028 code before taking it to the user.

[{"type":"thinking","thinking":"CRITICAL FINDING: the honest total **exceeds** Bn for n ≳ 5×10⁷ (ratio 1.012 at 10¹², 1.015 at 9×10²⁴). The slack at 10⁵ is 117k but it SHRINKS and goes negative around n ≈ 5×10⁷. So my honest pieces are worse than Bn asymptotically. Why? Let me diagnose which piece overshoots asymptotically.\n\nCompare growth rates:\n- Bn's I_III term: 4T·[(2/3)Ĉ₀ + 10.5 log + 48] ~ 4T·(10.5)·log T (leading, since (2/3)Ĉ₀ ~ 0.29 log T).\n- Honest I_III: 4T·[(2/3)Z2 + 10.5 log + 48]: Z2 ~ 0.6 log T vs Ĉ₀ ~ 0.433 log T: (2/3)·0.6 = 0.4 vs (2/3)·0.433 = 0.289: honest leading = 4T·(0.4 + 10.5)·log T vs baked 4T·(0.289+10.5)·log T: honest exceeds by 4T·0.111·log T — the I_III two-unit correction grows like T·log T and eventually eats the slack!\n\n- Bridge: honest 4F vs baked 2F: +2F ~ +0.318·T·log T — ALSO grows like T log T!\n\n- Horizontals: honest NI ~ Z2·2·log(148.5·C0hat) ~ 0.6L·2·log(148.5·0.433L) ~ 1.2L·log L vs baked 7Ĥ ~ 21·(0.433L)² = 3.94L²: the horizontal fit IMPROVES asymptotically (NI/(7Ĥ) → 0) ✓ (the ratio column: 0.398 → 0.241 decreasing ✓).\n\nSo the killers are the I_III two-unit correction (+4T·(0.111)·log T) and the bridge factor-2 (+2F ~ 0.318·T·log T): total extra ≈ 4T·0.111·log T + 0.318·T·log T ≈ (0.444+0.318)·T·log T ≈ 0.762·T·log T vs the horizontal slack (baked − honest) ≈ 2(e⁴+1)·(7Ĥ − NI−5.5·(10.5 log+48)) ~ 2(e⁴+1)·(3.94L² − 1.2L·log L − 5.5·10.5L) ~ 110·3.94L² ≈ 433·L². The slack grows like L² = (log T)² while the excess grows like T·log T — T = √n beats (log T)² eventually ⟹ crossover ~ 5×10⁷. CONFIRMED by the table.\n\nSo the honest pieces as I wrote them DON'T fit. Need to fix the two killers:\n\n**Fix 1 (I_III)**: the (2/3)·Z2 near-sum on the left vertical. The baked (2/3)Ĉ₀ charges the near-sum (|w−ρ| ≥ 3/2, count ≤ Ĉ₀). Honest count: two-unit Z2. But wait — the tight R-bound's near set (nearZeros t in the 5f capstone — the UNIT window [t-1, t+1]?) — 5f's capstone already charges the near sum with the TWO-UNIT count (D-069 Finding 1's fix is INSIDE the tight R-bound's 10.5·log+48). Wait no — the tight R-bound is ‖ζ′/ζ(s) − Σ_{near} m/(s−ρ)‖ ≤ 10.5·log+48 — the near sum Σ_{near} m/(s−ρ) is OUTSIDE the bound; it's charged separately by the CONSUMER. For the left vertical: Σ_{near} m/|w−ρ| ≤ (2/3)·(near count). The near count (nearZeros t = unit window? nearZerosSub — the subtype version) — what's its definition? From 5f: \"near ≤ P1-count ≤ 0.6·L + 0.886·LL + 2.7 (|s₀−ρ| ≥ 1 since re ρ ≤ 1)\" — the two-unit count Z2! So 5f's own near-sum charging uses Z2. The near sum is a TWO-unit window sum — its honest count is Z2 = 0.6L+0.886LL+2.7 — and Bn's baked (2/3)Ĉ₀ with Ĉ₀ = 0.433L+0.886LL+2.9 is SMALLER. So the I_III (2/3)Ĉ₀ term in Bn genuinely undercounts the near-sum on the left vertical — D-069 Finding 2 said exactly this: \"D-037's I_III (2/3)·Ĉ₀ coefficient gets the analogous two-unit correction to (4/3)-ish\".\n\nHmm — wait, \"(4/3)-ish\": (2/3)·Z2 ≈ (2/3)·(0.6/0.433)·Ĉ₀ ≈ (2/3)·1.386·Ĉ₀ ≈ 0.92·Ĉ₀ ≈ (4/3)·(2/3)Ĉ₀·... the (4/3) means the COEFFICIENT of Ĉ₀ goes from 2/3 to ~4/3?? (2/3)·Z2 with Z2 ≈ 1.4Ĉ₀ gives ≈ 0.93Ĉ₀ — that's a (2/3)→~0.93Ĉ₀ correction, i.e. coefficient of T·Ĉ₀ in 4T[...]: from 4·(2/3) = 2.67 to 4·0.93 = 3.7 — the \"(4/3)-ish\" must mean 4·(1/3)... whatever. The excess over baked: 4T·[(2/3)(Z2−Ĉ₀)] = 4T·(2/3)·[(0.6−0.433)L + (2.7−2.9)] = 4T·(2/3)·[0.167L − 0.2] ≈ 4T·0.111·L.\n\nCan this be avoided? YES — charge the near-sum on the left vertical more cleverly: the near-sum Σ m/|w−ρ| with |w−ρ| ≥ 3/2... the zeros are at distance ≥ 3/2 from the ENTIRE vertical line — but most near-window zeros are much farther: |w−ρ|² = (5/2−β)² + (t−γ)². Split the near window: zeros with |t−γ| ≥ 1 are in the R-part already. The near window |t−γ| < 1: |w−ρ| ≥ 3/2 exactly. Hmm — the (2/3) is tight for zeros with β → 1, γ → t. So the near-sum honestly needs the two-unit count × (2/3). UNLESS we bound the near-sum by the UNIT-window count on each of the two halves [t−1, t] and [t, t+1]: each ≤ Ĉ₀: total ≤ 2Ĉ₀ — worse than Z2 (Z2 ≈ 1.39Ĉ₀). So Z2 is the honest charge: I_III honest = 4T·[(2/3)Z2 + 10.5 log + 48] — EXCEEDS baked by 4T·(2/3)(Z2−Ĉ₀) ≈ 0.444·T·L — grows like T·L. KILLER confirmed.\n\nHmm — so how does the paper's B(n) survive?? The baked I_III uses (2/3)Ĉ₀ — undercounted per Finding 2. The Finding-2 doc says \"E-028's 26× slack says the theorem survives; the certified crossover artifacts move\". The THEOREM (λ_n > 0) survives because |Sf| is tiny; but SfBoundProp (|Sf| ≤ Bn baked) — the honest assembly does NOT prove it for large n. \n\nWait — unless the OTHER pieces' slack absorbs: the horizontals' slack grows like 433·L² ≈ 433·(log T)² — the killers grow like T·log T = √n·(0.5 log n) — at n = 9×10²⁴: T = 3×10¹², killers ≈ 0.762·3×10¹²·29 ≈ 6.6×10¹³; horizontal slack ≈ 433·841 ≈ 364,000. Utterly outgunned. What else has slack? The bridge 2F baked... I_I: negligible. 40M₀: constant. Hmm.\n\n**Rethink the bridge**: |λ_n(T)| ≤ 2·(both-signs mult count). Both-signs count = 2·N_classical(T) ≤ 2·FAlt(T)?? — is N_classical ≤ FAlt?? FAlt's comment: \"any literature bound N(T) ≤ F(T) + S_b(T) upgrades to N(T) ≤ FAlt(T)\" — yes N_classical ≤ FAlt. So both-signs ≤ 2·FAlt, bridge ≤ 4·FAlt. Baked: 2·FAlt. Killer +2·FAlt ~ 0.318·T·log T.\n\nHmm — wait: is the bridge's per-term bound really 2? |1 − (ρ/(ρ−1))ⁿ| ≤ 1 + |ρ/(ρ−1)|ⁿ = 2 on the line. BUT — a better bound for most zeros: for |γ| LARGE vs n... no, γ ≤ T ≈ √n and n ≥ 10⁵: nθ with θ = arg(ρ/(ρ−1)): ρ = 1/2+iγ: ρ/(ρ−1) = (1/2+iγ)/(−1/2+iγ): |w| = 1, arg ≈ π − 2·arctan(1/(2γ))·... ≈ π − 1/γ·...: w ≈ e^{i(π−1/γ)}: wⁿ ≈ e^{inπ − in/γ}: |1−wⁿ| can be up to 2. No uniform improvement. The honest bridge is 4·FAlt.\n\nBUT WAIT — maybe pair the terms! λ_n(T) = Σ mult·(1−(ρ/(ρ−1))ⁿ) over both signs. Pair ρ, ρ̄: (1−wⁿ) + (1−w̄ⁿ) where w̄ = conj(w)... on the line w̄ = w⁻¹: pair = 2 − (wⁿ + w⁻ⁿ) = 2 − 2cos(nθ) ≤ 4 = 2+2 per pair — same as 2 each. No gain.\n\nAlternatively — maybe charge the bridge with multiplicity... same.\n\nHmm OK — so both killers are real and grow like T·log T. The fold as I've designed it FAILS for n ≳ 5×10⁷. But wait — how did the PAPER's assembly (D-037/E-028) pass? The paper's |Sf| ≤ B(n) is only used through the MARGIN: margin = S_∞^lower − B + 1 > 0 on [N₀, N₁]. If the honest B_honest exceeds Bn beyond 5×10⁷, then the paper's B(n) itself is an UNDERCOUNT of the honest assembly beyond 5×10⁷ — meaning the paper's bound |Sf(n)| ≤ B(n) is NOT what the assembly proves there... BUT the theorem only needs margin > 0: margin_honest = S − B_honest + 1 — the killers add ≈ 0.762·T·log T ≈ 6.6×10¹³ at N₁ to B — while margin(N₁) = 2.458×10²⁶. So the THEOREM survives trivially. The issue is only the LEAN SfBoundProp which must match the BAKED Bn exactly (because lambda_pos_finite_height_verified consumes it).\n\nResolution options:\n(A) **Change SfBoundProp's Bn** to the honest form (edit LiSkeleton's Bn definition: bridge 2F → 4F... wait no — Bn's 2F term: baked is 2·FAlt. Honest bridge 4·FAlt. And I_III (2/3)Ĉ₀ → (2/3)Z2. Then margiñ machinery (marginTilde := sInftyLower − Bn + 1, the convexity proof, the base points) still works? marginTilde_convex is PROVED for the Bn-with-F-parameter... Bn F n uses F := FAlt parameter for the 2F term only; the rest is fixed. Changing Bn's definition changes marginTilde — the convexity proof (marginTilde_convex, D-057's ψ-table) is structural (each block's ψ < 0 — the I_III block (2/3)Z2 vs (2/3)Ĉ₀: Z2's ψ... the convexity proof would need re-verification for the changed blocks; the base points (margiñ(8×10⁴) ≥ 8001, margiñ(10⁵) ≥ 85 501) would DROP by the honest excess at those n (≈ 117k − 118k... wait at n=10⁵ honest < baked by 117k so margin INCREASES?? No wait — honest at 10⁵ is SMALLER (ratio 0.656) because the horizontal slack dominates there. So with honest pieces, B_honest(10⁵) = 224k < Bn(10⁵) = 342k — margin(10⁵) INCREASES by 118k! And at 8×10⁴ similar. So changing Bn to the honest form IMPROVES the base points and only requires re-checking the crossover region: the honest B is smaller near 10⁵, larger beyond 5×10⁷ — but margin > 0 throughout [N₀, N₁] regardless (the excess is ≪ margin). The convexity re-verification is structural (the changed blocks: 4F vs 2F — same F block ×2, ψ scales ×2 still negative; I_III (2/3)Z2: Z2 = 0.6L+0.886LL+2.7 — similar form to Ĉ₀ = 0.433L+0.886LL+2.9 — the ψ-table rows cover log/loglog forms ✓ structural re-verify, D-057's machinery applies).\n\nBut (A) edits LiSkeleton.lean (Bn def) — VIOLATES the freeze protocol? The freeze says: \"no edits to existing Lean proofs except the liCoeff correctness fix (ii′-1a)\". Editing Bn's definition would break downstream proofs (marginTilde_convex, base points, lambda_pos_finite_height_verified) — they'd need re-verification but the STATEMENTS (SfBoundProp, the theorem) would then be about the honest Bn. Hmm — but SfBoundProp is the hypothesis consumed by lambda_pos_finite_height_verified; if I change Bn, SfBoundProp changes meaning, and the theorem's statement... lambda_pos_finite_height_verified : ∀ n, 1 ≤ n → (n:ℝ) ≤ (3×10¹²−1)² → 0 < (liCoeff n).re — the FINAL statement is Bn-independent! The margin machinery is internal. So changing Bn internally is SAFE for the final statement: lambda_pos_finite_height_verified would still prove 0 < (liCoeff n).re from (hRH)(hfinite)(hSf) with hSf : SfBoundProp (redefined with honest Bn). And ii′-7's sfBoundProp : SfBoundProp would prove the honest version. The perimeter is unchanged.\n\nBUT the freeze protocol (user directive 2026-08-21): \"no edits to existing Lean proofs except the liCoeff correctness fix (ii′-1a)\". Editing Bn violates this — needs user approval. AND it invalidates the proved marginTilde_convex + base points (re-verification needed — structural, but real work: the ψ-table for the changed blocks + re-certified base points).\n\n(B) **Keep Bn; prove the honest pieces fit under Bn on [10⁵, N₁]** — IMPOSSIBLE per the numerics (honest > baked beyond 5×10⁷). UNLESS the honest pieces are sharpened: the killers are (i) bridge 2F extra, (ii) I_III two-unit extra. Can either be sharpened to fit under baked?\n(i) Bridge: the honest bridge is 4·FAlt. Could a sharper analysis give 2·FAlt? |λ_n(T)| = |Σ mult·(1−w_ρⁿ)| — the actual truncated sum. Hmm — the terms 1−wⁿ with |w| = 1: no cancellation provable in general (extremal: all wⁿ ≈ −1). So no: 4·FAlt is the honest worst case. The baked 2F is an undercount (the D-036/D-037 factor-2 slip).\n(ii) I_III: (2/3)Z2 vs (2/3)Ĉ₀: Z2 is the honest two-unit count. Could charge the near-sum as ≤ (2/3)·N(t+1)−N(t−1) with the GLOBAL count difference ≤ FAlt-difference + 2·S_b-parts... the global N(t+1)−N(t−1) ≤ F(t+1)−F(t−1) + 2·S_b(max) ≈ (1/π)log(t·...)·2... ≈ 0.318·log T + const — vs Ĉ₀ = 0.433L+0.886LL+2.9: the global difference (F(t+1)−F(t−1) + S_b(t+1)+S_b(t−1)) ≈ (2/2π)(log T + 1) + 2·(0.137L + 0.443LL + 1.588) = 0.318L + 0.274L + 0.886LL + 3.18 = 0.592L + 0.886LL + 3.18 vs Z2 = 0.6L+0.886LL+2.7 — nearly identical (0.592 vs 0.6). And vs Ĉ₀ = 0.433L+...: still the +0.16L excess. So no sharpening there — the two-unit excess is intrinsic.\n\nSo (B) is out: the baked Bn undercounts the honest assembly for n ≳ 5×10⁷. The baked SfBoundProp is still TRUE (|Sf| is tiny) but NOT PROVABLE via the contour assembly as baked.\n\n(C) **Narrow SfBoundProp's range**: SfBoundProp is consumed with n ∈ [10⁵, N₁]. What if the Lean assembly proves |Sf n| ≤ B_honest(n) and we ALSO prove B_honest(n) ≤ Bn(n) on a range where it holds — the numerics say it holds for n ≤ ~5×10⁷. For n > 5×10⁷... the margin proof needs |Sf| ≤ Bn for margin > 0 — but wait, for large n we could use a DIFFERENT bound: is there an alternative? Hmm no.\n\n(D) **Change the C0hat/Hhat constants inside Bn to honest forms** — same as (A) but more surgical: Bn's I_III block: 4T·[(2/3)Ĉ₀ + ...] → 4T·[(2/3)Z2 + ...]; bridge 2F → 4F. This is (A).\n\nSo (A) is the route: redefine Bn with the honest constants (bridge 4F, I_III (2/3)Z2), re-verify marginTilde_convex structurally + re-certify the base points (they IMPROVE since honest < baked near 10⁵). And SfBoundProp becomes the honest-Bn version — provable on [10⁵, N₁] (honest ≤ honest trivially; the fit issue disappears because SfBoundProp's Bn IS the honest bound).\n\nWait — but then does margin > 0 still hold on [N₀, N₁]? margin = S − B_honest + 1: at n = 10⁵: S ≈ 433,000... wait let me recompute: sInftyLower(10⁵) = ½·10⁵·log(10⁵) + (C₁−γ/2)·10⁵ − 4 = ½·10⁵·11.513 − 1.41894·10⁵ − 4 = 575,650−141,894−4 = 433,752. B_honest(10⁵) = 224,000. margin = 209,000 > 0 ✓ (BIGGER than the baked margin 93k!). At N₁: excess over baked ≈ 6.6×10¹³ ≪ margin(N₁) ≈ 2.46×10²⁶ ✓. The crossover: honest B is smaller near 10⁵, larger beyond ~5×10⁷ — the crossover n where margin becomes positive: with smaller B near 10⁵ the crossover moves DOWN (better). ✓ All good — margin > 0 on [N₀, N₁] trivially survives (the excess at N₁ is 10⁻¹³ relative).\n\nThe cost of (A): edit LiSkeleton.lean's Bn (+ marginTilde machinery is F-parameterized — Bn F n has F only in the 2F term: changing to 4F means Bn's F-term doubles: Bn F n = 4·F T + ...? Hmm — actually wait: is the honest bridge 4·FAlt or 2·(both-signs count) with both-signs ≤ 2·FAlt? FAlt majorizes the ONE-sign N(T). The Lean bridge: |λ_n(T)| ≤ 2·(Σ_{both} mult) ≤ 2·(2·FAlt T) = 4·FAlt T. So Bn's 2F term → 4F term. And the I_III (2/3)Ĉ₀ → (2/3)Z2. These edits touch:\n- Bn def (LiSkeleton:2413).\n- marginTilde_eq_sub + the mK-style constants? (LiSkeleton:1819 mK has −40·1.3352 etc. — used in convexity).\n- marginTilde_convex (session 011 proof — the ψ-table: the F-block ×2 and the I_III block changed → re-verify those rows; structural but must be redone).\n- The base points LiBasePoints (margiñ(8×10⁴) ≥ 8001, margiñ(10⁵) ≥ 85 501 — with honest B SMALLER at those points, the certified bounds still hold... wait: honest B(10⁵) = 224k < baked 342k ⟹ margiñ(10⁵) = S − B_honest + 1 = BIGGER ⟹ the certified lower bounds (≥ 8001, ≥ 85 501) remain TRUE but the certified values are now loose — actually the certified computations must be REDONE because Bn's definition changed (the proof of marginTilde_FAlt_80000_pos computes the value from Bn's definition — changing the def changes the value — the certified bound ≥ 8001 would still hold since the new value is bigger, but the PROOF term evaluates the old def — broken proofs need re-verification).\n\nThis is real work but bounded: the convexity rows for the changed blocks + the two base-point certificates. It VIOLATES the freeze protocol (edits existing proofs) — needs explicit user approval.\n\n(E) **Alternative: leave Bn frozen; make SfBoundProp's statement use Bn but prove it via a DIFFERENT argument for the excess pieces** — e.g., prove |Sf n| ≤ B_honest(n) AND B_honest(n) ≤ Bn(n) on [10⁵, N₁]?? — numerics say FALSE beyond 5×10⁷. Out.\n\n(F) **Leave Bn frozen; prove |λ_n(T)| ≤ 2·FAlt via a SMARTER bridge**: pair-conjugate accounting! λ_n(T) = Σ_{both} mult·(1−w_ρⁿ): group conjugate pairs: Σ_{γ>0} mult·[(1−wⁿ)+(1−w̄ⁿ)] = Σ_{γ>0} mult·(2−2Re wⁿ) — the pair sum ≤ 4 per pair (mult·... wait mult per zero; pair = mult·(2 − wⁿ − w̄ⁿ) = mult·(2−2Re wⁿ) ≤ 4·mult = 2·(2·mult) — the pair contributes ≤ 4·mult, i.e. 2·mult per zero — same as before. |λ_n(T)| ≤ Σ_{γ>0} 4·mult = 4·N_classical ≤ 4·FAlt. SAME. No improvement — because |2−2Re wⁿ| ≤ 4 is tight.\n\nSo (A) is the route. The paper's B(n) has the factor-2 bridge slip + the I_III two-unit slip — BOTH must be corrected in the paper too (erratum list for ii′-7's paper update: D-037 line-63 erratum pointer already planned — add these). And E-028's margin computations used the baked (undercounted) B(n) — the theorem survives because the corrections are ≪ margins (verified numerically above: at 10⁵ honest < baked; the crossover region is FINE because honest B near 8×10⁴–10⁵ is SMALLER than baked — the crossover moves DOWN if anything; and at N₁ the excess is 10⁻¹³ relative). Wait — careful: the paper's margin(N₀) at N₀ = 8×10⁴ uses baked B — with honest B SMALLER there, margin(8×10⁴) is BIGGER — crossover still ≤ 75,451 ✓. And margiñ' > 0 direction: honest B grows slightly faster (extra T·log T terms) — margin' = S' − B' — at N₀, S' ≈ ½(log n + 1) − ... vs B' — the margin-derivative sign near the crossover needs a re-check but with margin(8×10⁴) = 15,764 + honest-slack(≈ 117k at 10⁵, ≈ 110k at 8×10⁴?) — the margin at 8×10⁴ with honest B ≈ 15,764 + (342k−224k scaled) — bigger — and the convexity argument (structural) re-verifies. Fine.\n\nOK so the design decision (A) is clear: **redefine Bn honestly** (bridge 4F, I_III (2/3)Z2), keep SfBoundProp's RANGE [10⁵, N₁], re-verify margin convexity structurally + re-certify base points (they improve), fix the paper at ii′-7 (errata: D-036 §4 + D-037 (4.1) factor-2 bridge + I_III two-unit count — the theorem R-004 unaffected).\n\nHmm wait — actually, hold on. Let me reconsider once more. Is there a way to keep Bn untouched AND make the fold work? The killers: bridge +2F, I_III +4T·(2/3)(Z2−Ĉ₀). Total extra at N₁ ≈ 6.6×10¹³ ≈ 1.5% of Bn(N₁) = 4.37×10¹⁵. What if instead of the horizontals' segment-integral (which I used to CREATE slack), I check: does the baked horizontals 2(e⁴+1)[7Ĥ+3.3] cover the honest horizontals with Finding-2's honest-MAX (7Ĉ₀²+8Ĉ₀+A log+B₀)? Honest-max horizontal inside: 7·(7Ĉ₀²+8Ĉ₀+10.5 log+48)+3.3 vs baked 7·(3Ĉ₀²+10.5 log+48)+3.3: honest-max exceeds by 7·(4Ĉ₀²+8Ĉ₀) ≈ 28Ĉ₀² ≈ 28·(0.433L)² ≈ 5.25·L² — ×2(e⁴+1) ≈ 110: ≈ 578·L² — grows like L², same order as the baked Ĥ's L²... at N₁: 578·841 ≈ 486k — trivial vs the T·log T killers. So the horizontal near-sum form (max vs integral) is IRRELEVANT to the killers. The killers are intrinsic (bridge factor 2 + I_III two-unit count). No fold trick avoids them. (A) is forced.\n\nHmm, wait — actually one more: could the bridge avoid the both-signs count by choosing the rectangle to only enclose the UPPER zeros? The rectangle is [−T, T] in im — symmetric. Could we use a rectangle [0, T]×im? The residue theorem needs a closed contour around 1 and the zeros... Lagarias's contour is symmetric because Jlag's poles include ALL zeros (both signs) inside. A half-rectangle [−5/2, 2√n]×[0, T] would enclose only upper zeros — but then the bottom side is the REAL segment [−5/2, 2√n] crossing 1 (the pole!) and trivial zeros — no good. The symmetric contour is required. So both-signs count is intrinsic. (A) forced. \n\nHmm, OR: pair the conjugate terms BEFORE bounding: λ_n(T) = Σ_{γ>0} mult·(2 − 2Re(w_ρⁿ)) — |2−2Re wⁿ| ≤ 4 — the SAME 4·mult per pair. |λ_n(T)| ≤ 4·N_classical. Same. OK.\n\nHmm hmm — wait, one more idea for the bridge: 2 − 2Re wⁿ with w = ρ/(ρ−1), ρ = 1/2+iγ: w = e^{iθ} with θ = π − 2 arctan(1/(2γ))·... θ ≈ π − 1/γ for large γ. wⁿ ≈ e^{inθ}: 2−2cos(nθ). For this to be near 4 need nθ ≈ π mod 2π: n(π − 1/γ) ≈ π: n − n/(γπ) ≈ 1 mod 2 — possible for some (n, γ). No uniform improvement. OK truly (A).\n\nWait, actually, hold on — let me reconsider the bridge once more. |λ_n(T)| ≤ 2·Σ mult where Σ is the both-signs mult-count. Both-signs mult-count = 2·N_classical (if all mult = 1) — but mult can be > 1 (we don't have simplicity!). mult-weighted both-signs = 2·(mult-weighted one-sign) ≤ 2·FAlt — hmm wait: does the mult-weighting change anything? FAlt majorizes the mult-weighted one-sign count (Trudgian's N(T) counts zeros WITHOUT multiplicity classically! N(T) = #zeros — Trudgian's bound is on the count of zeros (distinct), not mult-weighted!). Hmm — but mult > 1 would make the mult-weighted count bigger than N(T). Does Trudgian's bound cover mult-weighted? N(T) with multiplicity = N(T) without (the count is the same sum with mult — standard: N(T) counts with multiplicity). Actually the classical N(T) counts WITH multiplicity (it's the winding number). And F(T)+S(T) bounds it. So mult-weighted one-sign ≤ FAlt ✓ consistent with ZeroCountProp being mult-weighted ✓.\n\nOK. Decision (A) confirmed. But it requires editing LiSkeleton.lean (Bn def + downstream re-verification) — a freeze-protocol exception requiring USER APPROVAL. Also the two perimeter formalizations (ZeroCountGlobalProp, MZeroProp) — approval as well (they're within the already-approved trust classes).\n\nGiven the stakes, I should present this to the user NOW — the design review with the two findings (bridge factor-2 slip in the paper; I_III two-unit slip) and the required decisions:\n1. Approve Bn redefinition (freeze exception) — honest constants: bridge 4F, I_III (2/3)Z2 — with re-verified convexity + base points (they IMPROVE: honest B < baked B near 10⁵).\n2. Approve the two perimeter formalizations (ZeroCountGlobalProp global Trudgian N(T) ≤ FAlt; MZeroProp M₀ ≤ 1.3352) — same trust classes as already approved.\n3. Note for the paper erratum list (ii′-7): D-036 §4/D-037 (4.1) bridge factor-2 + I_III two-unit count slips; theorem R-004 unaffected (corrections ≪ margins, verified numerically).\n\nHmm — wait, actually, before going to the user, let me double-check the factor-2 bridge claim once more by looking at how E-023/E-028 actually computed the zero-sum bound...
