Summary

Focus: ii′-5e-v — circle bounds (research sessions 030–033).

What happened:

  • The far-tail bound via the dyadic fiber machine (Σ_{|γ|>X} m/(1+γ²) ≤ 16·A₀·log X/X).
  • The series circle bound and the Fexpr circle bound O((log R)³) on the γ-gap circles (three-region logDeriv assembly).

Outcome: the growth estimate for the Schwarz squeeze was in hand; user took a break at a clean boundary.

Now let me read the current LiCircleBound.lean to see what's there and plan chunk 3 — the main seriesFun circle bound `seriesFun_norm_le_gapCircle`. The task (from STATE.md NEXT ACTION): 1. ‖seriesFun s‖ ≤ ∑' ρ, m·R/(‖ρ‖·‖s−ρ‖) via norm_tsum_le_tsum_norm + per-term norm identity from one_div_sub_add_one_div (needs ζ s ≠ 0 on the circle — discharged via re ≥ 1 nonvanishing, dist(R/2,ℤ) ≥ 1/4, γ-gap + threshold lemma). 2. THRESHOLD LEMMA (k ≥ 4000): 16·Ĉ₀(4k+9/2)·26 ≤ 4k+2-ish — explicit linear/rational arithmetic. 3. ONE tsum_split_finset at F := {‖ρ‖ ≤ 2R} + tail via zero_tail_inv_sq_le. 4. The finite part by Finset.filter: low / inner-low / inner-high / critical / upper bands, each dyadic with Ncount_le_of_interval_gen. Let me read the current file first to see exactly what's available.

I have all the API I need. Now let me plan chunk 3 carefully. **Goal:** `seriesFun_norm_le_gapCircle` — on the γ-gap circle |s| = R (from `exists_gapCircle_radius`), bound ‖seriesFun s‖ ≤ C·A₀·(log R)²-ish. The design from STATE.md: 1. ‖seriesFun s‖ ≤ ∑' ρ, m·R/(‖ρ‖·‖s−ρ‖) via norm_tsum_le_tsum_norm + per-term norm identity (needs ζ s ≠ 0 on the circle). 2. THRESHOLD LEMMA (k ≥ 4000): 16·Ĉ₀(4k+9/2)·26 ≤ 4k+2-ish. 3. ONE tsum_split_finset at F := {‖ρ‖ ≤ 2R} + tail via zero_tail_inv_sq_le. 4. The finite part by Finset.filter into low / inner-low / inner-high / critical / upper bands. Wait — actually let me think about the structure of the bound more carefully. The term is: ‖seriesTerm s ρ‖ = mult·‖s‖/(‖ρ‖·‖s−ρ‖) = m·R/(‖ρ‖·‖s−ρ‖). Shell bounds: - low (‖ρ‖ ≤ 3): m·R/(‖ρ‖·‖s−ρ‖). With ‖s‖ = R, ‖ρ‖ ≤ 3, R ≥ 4k+2.5 ≥ 16000ish, ‖s−ρ‖ ≥ R−3 ≥ R/2. So term ≤ m·R/(‖ρ‖·(R−3)) ≤ 2m/‖ρ‖. Sum ≤ 2·lowZeroConst. (lowZeroConst = Σ m·(1+1/‖ρ‖), and 2/‖ρ‖ ≤ 2·(1+1/‖ρ‖), so ≤ 2·lowZeroConst.) Fine — but lowZeroConst needs ‖ρ‖ ≤ 3 membership, the term needs to be compared when ‖ρ‖ ≤ 3 AND ‖ρ‖ ≤ 2R (finite part). - inner-low (3 < ‖ρ‖ ≤ R/2): ‖s−ρ‖ ≥ R − ‖ρ‖ ≥ R/2 ≥ ‖ρ‖ (since ‖ρ‖ ≤ R/2). Term ≤ m·R/(‖ρ‖·(R/2)) = 2m/‖ρ‖. Dyadic in ‖ρ‖: zeros with ‖ρ‖ ∈ (2^j, 2^{j+1}], j from 2 to log₂(R/2). |γ| ≥ ‖ρ‖ − 1 via norm ≤ |re|+|im|. Count via Ncount_le_of_interval_gen on [2^j−1, 2^{j+1}] hmm... Actually per design: "inner-low (3 < ‖ρ‖ ≤ R/2: term ≤ 2/‖ρ‖, dyadic in ‖ρ‖, counts via Ncount_le_of_interval_gen)". So the contribution: Σ_j (2/2^j)·A₀·(2^j+1+1)·log(3·2^{j+1}+5) ≈ Σ_j 2·A₀·log(...) ≈ O(A₀·(log R)²) over J ≈ log₂ R terms. - inner-high (R/2 < ‖ρ‖ ≤ R−2): ‖s−ρ‖ ≥ R−‖ρ‖ ≥ 2. Term ≤ m·R/(‖ρ‖·(R−‖ρ‖)) ≤ m·R/((R/2)·(R−‖ρ‖)) = 2m/(R−‖ρ‖). Dyadic in R−‖ρ‖: R−‖ρ‖ ∈ [2^j, 2^{j+1}), ‖ρ‖ ∈ (R−2^{j+1}, R−2^j]. |γ| ≥ ‖ρ‖−1 ≥ R−2^{j+1}−1 ≈ R/2ish. Count via Ncount window of width 2^{j+1} at height ~R: ≤ A₀·(2^{j+1}+1)·log(3R+5). Term ≤ 2/2^j. Contribution per j: 2·2^{−j}·A₀·(2^{j+1}+1)·log ≈ 8·A₀·log. Number of j's: log₂(R/2−2)... hmm R−‖ρ‖ ranges from 2 to R/2, so J ≈ log₂ R terms. Total O(A₀·(log R)²). - critical (R−2 < ‖ρ‖ < R+2): split on |im s|: - strip arcs (|im s| ≥ 10): re s ∈ [−√(R²−100), √(R²−100)] — wait no. |s| = R, |im s| ≥ 10 ⟹ |re s| ≤ √(R²−100) < R. And for the zero ρ with ‖ρ‖ ≈ R and |re ρ| ∈ (0,1), |γ| = |im ρ| ≥ ‖ρ‖−1 ≥ R−3. Then |s−ρ| ≥ |im s − γ|... hmm need care with signs. |s−ρ| ≥ |im(s−ρ)| = |t−γ| where t = im s. Now |t| ≤ R, |γ| ≥ R−3. | |t| − |γ| | ≤ 3... that's not directly a gap. The γ-gap is about |γ − R|. Let me reconsider: |t − γ| ≥ | |γ| − |t| | when t,γ have same sign... no wait: |t−γ| ≥ ||t|−|γ|| is always true (reverse triangle). Hmm but the design says "strip arcs |s−ρ| ≥ |t−γ| ≥ 1/(32Ĉ₀) via the γ-gap + |R−|t|| ≤ 13/R". Let me redo this: for |s| = R with |im s| ≥ 10: |t| = |im s| ≥ 10, and |t| ≤ R. Also R − |t| = (R²−t²)/(R+|t|) = re²/(R+|t|) ≤ re²/R. If |t| ≥ 10 then |re| ≤ √(R²−100), so R−|t| ≥ R−√(R²−100) = 100/(R+√(R²−100)) ≥ 50/R. Hmm that's a lower bound on R−|t|, but we need an upper bound: |R−|t|| = R−|t| ≤ R − 10... that's big. Hmm. Wait, I think I have the geometry wrong. Let me re-read the design: "critical (R−2 < ‖ρ‖ < R+2: strip arcs |s−ρ| ≥ |t−γ| ≥ 1/(32Ĉ₀) via the γ-gap + |R−|t|| ≤ 13/R; near-axis arcs ‖s−ρ‖ ≥ |re s|−1 ≥ √(R²−100)−1 ≥ R/2 — the split on |im s| ≥ 10 vs < 10)". OK so the split is on the point s on the circle: - Case |im s| ≥ 10 (strip arcs — most of the circle): Then re s ∈ [−√(R²−100), √(R²−100)]. Hmm, and |R − |t||: |t| = √(R²−re²) ≥ √(R²−(R²−100)) = 10, and |t| ≤ R. So |R−|t|| = R−|t| ≤ R−10. That's NOT ≤ 13/R. Hmm. Wait — maybe the split is |im s| < 10 for strip?? No wait. Let me think again. The point of the γ-gap: |t−γ| where t = im s. We have |t−γ| ≥ ||t|−|γ||... but the γ-gap gives |γ−R| ≥ 1/(16Ĉ₀) (or ≥ 1). If t and γ have the same sign: |t−γ| ≥ | |t|−|γ| | ≥ | R − |γ| | − | R−|t| |... by reverse triangle: ||t|−|γ|| ≥ ||γ|−R| − ||t|−R|. So if ||t|−R| ≤ 1/(32Ĉ₀) — i.e., |t| is CLOSE to R — then |t−γ| ≥ 1/(16Ĉ₀) − 1/(32Ĉ₀) = 1/(32Ĉ₀). |t| close to R means re s small: |t| = √(R²−re²) ≥ R−re²/R... R−|t| = re²/(R+|t|) ≤ re²/R. So R−|t| ≤ 13/R iff re² ≤ 13 (for |t| ≤ R). Hmm, so the "strip arcs" are where |re s| ≤ √13?? That's the strip near the top/bottom of the circle where re s ∈ (0,1)-ish — i.e., s is in the critical strip region! Yes — that makes sense: "strip arcs" = the part of the circle passing through the critical strip (near the top, im ≈ ±R, re ∈ [−4,4] say). There |t| ≈ R, so |t−γ| ≈ |R−γ| ≥ 1/(16Ĉ₀) by the gap (or ≥ 1), and R−|t| = re²/(R+|t|) ≤ 16/R... the design says ≤ 13/R (re² ≤ 13 ⟸ |re| ≤ √13 ≈ 3.6, hmm, maybe |re| ≤ 3: re² ≤ 9, 9/(R+|t|) ≤ 9/R... or 13 for |re| ≤ √13). And "near-axis arcs" = |im s| < 10, where |re s| ≥ √(R²−100) (s near ±R on the real axis). There |s−ρ| ≥ |re(s−ρ)| = |re s − re ρ| ≥ |re s| − 1 ≥ √(R²−100) − 1 ≥ R/2. OK so the split is on |im s| ≥ 10 vs |im s| < 10. For |im s| ≥ 10... wait, that doesn't match: if s is near the top of the circle (strip arc), then im s ≈ ±R which has |im s| ≥ 10 for R ≥ 10. And near-axis arcs have |im s| < 10 (s near the real axis). But then for the strip arc bound |t−γ| ≥ 1/(32Ĉ₀), we need |re s| ≤ √13 to get R−|t| ≤ 13/R. But the strip arc |im s| ≥ 10 only gives |re s| ≤ √(R²−100), which is ≈ R, huge! Hmm wait. Let me reconsider. Actually I bet the split for the critical annulus zeros is different. Let me think about which (s, ρ) pairs are dangerous: ‖ρ‖ ∈ (R−2, R+2), so |γ| ≥ ‖ρ‖−1 ∈ (R−3, R+1) or |γ| ≤ ‖ρ‖+1... |γ| ∈ (R−3, R+3)-ish. |s−ρ|² = (re s − re ρ)² + (t−γ)². Dangerous case: t ≈ γ (same sign, both ≈ ±R) AND re s ≈ re ρ (small). That's exactly s in the strip arcs: |re s| ≤ ~4 and |im s| ≈ R. If |re s| > 4: then |s−ρ| ≥ |re s − re ρ| ≥ |re s| − 1 > 3. Fine, no gap needed. If |re s| ≤ 4: then R−|t| = re²/(R+|t|) ≤ 16/R. And |t−γ|: if t and γ same sign, |t−γ| ≥ ||t|−|γ|| ≥ |R−|γ|| − |R−|t|| ≥ 1/(16Ĉ₀) − 16/R ≥ 1/(32Ĉ₀) provided 16/R ≤ 1/(32Ĉ₀), i.e., R ≥ 512·Ĉ₀ — the threshold lemma! (STATE says "16·Ĉ₀(4k+9/2)·26 ≤ 4k+2-ish" — 26 ≈ ... hmm 16·26 = 416, close to 512·... well the exact numbers will come out in the wash; the design says 13/R not 16/R, so |re| ≤ √13.) If t, γ opposite signs: |t−γ| = |t|+|γ| ≥ |γ| ≥ R−3 ≥ R/2. Fine. So actually the split for the critical shell should be on |re s|, not |im s|. But the design says "the split on |im s| ≥ 10 vs < 10". Hmm, and the design's near-axis bound: ‖s−ρ‖ ≥ |re s|−1 ≥ √(R²−100)−1 ≥ R/2 uses |im s| < 10 ⟹ |re s| ≥ √(R²−100). And the strip arcs |im s| ≥ 10... for those, |re s| ≤ √(R²−100). But then R−|t| = re²/(R+|t|) where re² ≤ R²−100: that gives R−|t| ≤ (R²−100)/(R+|t|) = (R−|t|)(R+|t|)/(R+|t|) — circular. With |t| ≥ 10: R−|t| = (R²−t²)/(R+|t|) = re²/(R+|t|). To get R−|t| ≤ 13/R need re²·... hmm with |t| ≥ 10, R+|t| ≥ R, so R−|t| ≤ re²/R. Still need re² ≤ 13. Wait, maybe I'm misreading: perhaps the design intends |im s| ≥ 10 for the STRIP arc but additionally |re s| ≤ √13 is automatic?? No... Hmm, let me reconsider. Maybe the split is THREE-way for the critical shell: - s with |re s| ≤ √13 (strip arcs — includes both |t|≥10 automatically since R big): use the γ-gap. - s with |re s| > √13: |s−ρ| ≥ |re s| − 1 ≥ √13 − 1 ≥ 2.6 — a CONSTANT lower bound. That's plenty (no log factor)! Actually that's even better — no need for the |im s| < 10 case with the √(R²−100) business. But the design in journal-030 says: "near-axis arcs ‖s−ρ‖ ≥ √(R²−100)−1 ≥ R/2 — NO gap needed there" and STATE says "near-axis arcs ‖s−ρ‖ ≥ |re s|−1 ≥ √(R²−100)−1 ≥ R/2". So the design splits the CIRCLE (all shells, not just critical) into strip arcs (|im s| ≥ 10) vs near-axis arcs (|im s| < 10)? Hmm wait, but that split (|im s| ≥ 10 everywhere on the circle) is for the LOGDERIV assembly (5e-v-c), where the strip arcs need re ∈ [−5/2, 7/2] hmm no... Let me re-read journal-030's design for the logDeriv: "logDeriv ζ on the circle: strip arcs (re ∈ [−5/2, 7/2], |t| ≥ 10 for R ≥ 11): 5c/5d capstones... right near-axis (re ≥ √(R²−100) ≥ 2): the Dirichlet bound; left near-axis (re ≤ −√(R²−100)): 5d's logDeriv_zeta_fe..." — so for the logDeriv assembly the circle is split three ways: strip arcs (|re| ≤ ~7/2-ish, |t| ≥ 10), right near-axis (re ≥ √(R²−100)), left near-axis (re ≤ −√(R²−100)). Note √(R²−100) ≥ 7/2 for R ≥ ~11. For the SERIES bound (this chunk), the critical shell analysis: the design says "strip arcs |s−ρ| ≥ |t−γ| ≥ 1/(32Ĉ₀) via the γ-gap + |R−|t|| ≤ 13/R; near-axis arcs ‖s−ρ‖ ≥ |re s|−1 ≥ √(R²−100)−1 ≥ R/2 — the split on |im s| ≥ 10 vs < 10". Hmm OK here's the thing: for the strip arc bound via the γ-gap, we need |re s| small (≤ √13). But the strip arcs as defined (|im s| ≥ 10) allow re s up to √(R²−100). Contradiction... UNLESS the intended split is: - |im s| ≥ 10 AND |re s| ≤ √13-ish: γ-gap bound. - otherwise: |s−ρ| ≥ max(|re s|−1, ...) — wait for |im s| ≥ 10 with |re s| > √13, |s−ρ| ≥ |re s|−1 ≥ √13−1 ≈ 2.6 (constant, fine). For |im s| < 10: |re s| ≥ √(R²−100) ⟹ |s−ρ| ≥ √(R²−100)−1 ≥ R/2. So the real split for the critical shell: |s−ρ| ≥ min over cases. The cleanest formalization: - If |re s| ≤ √13 (⟹ R−|t| ≤ 13/R): |s−ρ| ≥ |t−γ| ≥ | |γ| − |t| |... need same-sign vs opposite-sign: opposite sign ⟹ |t−γ| ≥ |γ| ≥ R−3. Same sign ⟹ |t−γ| ≥ |R−|γ|| − 13/R ≥ 1/(16Ĉ₀) − 13/R ≥ 1/(32Ĉ₀) by the threshold. - If |re s| > √13: |s−ρ| ≥ |re s| − 1 ≥ √13 − 1 ≥ 5/2. So in ALL cases on the critical shell: ‖s−ρ‖ ≥ min(1/(32Ĉ₀), 5/2) = 1/(32Ĉ₀) (since Ĉ₀ ≥ 2 ⟹ 32Ĉ₀ ≥ 64 ⟹ 1/(32Ĉ₀) ≤ 1/64 ≤ 5/2). Then the critical-shell term: m·R/(‖ρ‖·‖s−ρ‖) ≤ m·R/((R−2)·(1/(32Ĉ₀))) = 32Ĉ₀·m·R/(R−2) ≤ 64·Ĉ₀·m (R/(R−2) ≤ 2 for R ≥ 4). Count of critical-shell zeros (mult-weighted): |γ| ≤ ‖ρ‖ ≤ R+2 and |γ| ≥ ‖ρ‖−1 ≥ R−3. So Ncount(−R−2, −R+3] + Ncount(R−3, R+2] ≤ 2·A₀·6·log(3(R+2)+5) = 12·A₀·log(3R+11). Total critical ≤ 64·Ĉ₀·12·A₀·log(3R+11) = 768·Ĉ₀·A₀·log(3R+11) = O(A₀·Ĉ₀·log R). Good — matches D-068 C1's O((log R)²·Ĉ₀)-ish... wait Ĉ₀ itself is O(log R loglog R), fine, that's part of the design (the R-bound ends up O((log R)³) after including Ĉ₀ ~ log). - upper shell (R+2 ≤ ‖ρ‖ ≤ 2R): ‖s−ρ‖ ≥ ‖ρ‖−R ≥ 2. Term ≤ m·R/(‖ρ‖·(‖ρ‖−R)) ≤ m·R/(R·(‖ρ‖−R)) = m/(‖ρ‖−R). Dyadic in ‖ρ‖−R ∈ [2^j, 2^{j+1}): term ≤ m/2^j; count: |γ| ≤ ‖ρ‖ ≤ R+2^{j+1}, |γ| ≥ ‖ρ‖−1 ≥ R+2^j−1. Ncount window width 2^{j+1}+1 at height R+2^{j+1}: ≤ A₀(2^{j+1}+2)log(3(R+2^{j+1})+5). Per-j: 2^{-j}·A₀·(2^{j+1}+2)·log(3(R+2^{j+1})+5) ≈ 4·A₀·log. J ≈ log₂ R terms. Total O(A₀·(log R)²). - tail (‖ρ‖ > 2R): seriesTerm_norm_le (needs 2‖s‖ ≤ ‖ρ‖, i.e. ‖ρ‖ ≥ 2R ✓, and ‖ρ‖ ≥ 2 ✓): term ≤ (17/6)·R·m/(1+‖γ‖²). Sum over ‖ρ‖ > 2R. Now ‖ρ‖ > 2R ⟹ |γ| ≥ ‖ρ‖−1 > 2R−1. So the tail ≤ (17R/6)·Σ_{|γ|>2R−1} m/(1+‖γ‖²) hmm but zero_tail_inv_sq_le is in terms of 1/(1+im²) not 1/(1+‖γ‖²). Let me check: tailTerm X ρ = m/(1+im²) for |im| > X. And 1+‖γ‖² vs 1+im²: ‖γ‖² = im²+(1/2−re)², and from tailTerm_summable: 1+‖γ‖² ≤ 2(1+im²). So 1/(1+‖γ‖²) ≥ 1/(2(1+im²)). Hmm we need an UPPER bound on the tail, so we need 1/(1+‖γ‖²) ≤ something with im. ‖γ‖² = im² + (1/2−re)² ≥ im² ⟹ 1/(1+‖γ‖²) ≤ 1/(1+im²). Good direction! So tail ≤ (17R/6)·Σ_{|γ|>2R−1} m/(1+γ²)... wait but the sum over ‖ρ‖ > 2R of m/(1+‖γ‖²) is over a SUBSET of {|γ| > 2R−1}... hmm, need {|γ| > 2R−1} ⊇ {‖ρ‖ > 2R}: ‖ρ‖ > 2R ⟹ |im ρ| = |γ| ≥ ‖ρ‖ − |re| > 2R−1 ✓. So Σ_{‖ρ‖>2R} m/(1+‖γ‖²) ≤ Σ_{|γ|>2R−1} m/(1+im²) = tailTerm-sum ≤ 16·A₀·log(2R−1)/(2R−1) (zero_tail_inv_sq_le, needs 2R−1 ≥ 200 ✓ for R ≥ 100.5, and k ≥ 4000 gives R ≥ 16002). Hmm wait — zero_tail_inv_sq_le's LHS is ∑' ρ, tailTerm X ρ = Σ_{|γ|>X} m/(1+im²). But we need to relate Σ_{‖ρ‖>2R} (as an if-zeroed tsum from tsum_split_finset) to it. The tsum_split_finset gives: ∑' ρ, f ρ = Σ_{ρ ∈ F} f ρ + ∑' ρ, (if ρ ∈ F then 0 else f ρ) where f ρ = m·R/(‖ρ‖·‖s−ρ‖)... Hmm wait, actually let me restructure. The design step 1 says first bound ‖seriesFun s‖ ≤ ∑' ρ, ‖seriesTerm s ρ‖, then per-term identity: ‖seriesTerm s ρ‖ = m·R/(‖ρ‖·‖s−ρ‖) — this needs the term to be written via one_div_sub_add_one_div, requiring s−ρ ≠ 0 (ζ s ≠ 0 argument) and ρ ≠ 0. Then define g ρ := (zeroMult ρ:ℝ)·R/(‖ρ‖·‖s−ρ‖), and bound ∑' ρ, g ρ via tsum_split_finset at F := {‖ρ‖ ≤ 2R} (as a finset of the subtype — needs finiteness from finite_subtype_norm_lt). Then: - The finite part Σ_{ρ∈F} g ρ splits via Finset.filter into the shells. But shells are defined by ‖ρ‖ ranges — use successive filters. Might be cleaner: partition F into disjoint finsets F_low (‖ρ‖ ≤ 3), F_inlo (3 < ‖ρ‖ ≤ R/2), F_inhi (R/2 < ‖ρ‖ ≤ R−2), F_crit (R−2 < ‖ρ‖ < R+2), F_up (R+2 ≤ ‖ρ‖ ≤ 2R). These are disjoint and cover F (for R ≥ 6). Sum = sum over pieces via Finset.sum over filter... or just bound each by filtering. - The tail ∑' ρ, if ρ ∈ F then 0 else g ρ: bound each nonzero term via seriesTerm_norm_le's conclusion hmm — actually g ρ was DEFINED as m·R/(‖ρ‖·‖s−ρ‖) which for ‖ρ‖ > 2R is ≤ (17/6)R·m/(1+‖γ‖²) — the seriesTerm_norm_le proof route. Then ∑' over the tail ≤ (17R/6)·Σ_{|γ|>2R−1} m/(1+im²) — but the if-zeroed tsum is over the subtype with indicator; need to dominate by tailTerm (2R−1) and use tsum_le_tsum. tailTerm's summability is proved (tailTerm_summable). And the if-zeroed g is summable (from the split machinery or by domination). Hmm — but there's a subtlety: g ρ involves ‖s−ρ‖⁻¹ which is fine, but the bound (17/6)R·m/(1+‖γ‖²) was for ‖seriesTerm s ρ‖, and g ρ = ‖seriesTerm s ρ‖ when the identity holds (s−ρ ≠ 0). Since we established ζ s ≠ 0 on the circle ⟹ s ≠ ρ for all nontrivial ρ, the identity holds for ALL ρ. Good — so actually we can set g ρ := ‖seriesTerm s ρ‖ directly and prove g ρ = m·R/(‖ρ‖·‖s−ρ‖) as a lemma. Plan of the Lean build for chunk 3: **Lemma A (ζ s ≠ 0 on the circle / no nontrivial zero on the circle):** for s with ‖s‖ = R (R from the gap circle, k ≥ 1), s is not a nontrivial zero. Proof: suppose IsNontrivialZero s. Then re s ∈ (0,1), so im s ≠ 0 and |im s| = √(R²−re²). |R − |im s|| = R − √(R²−re²) = re²/(R+√(R²−re²)) ≤ 1/R (since re² ≤ 1 and R+√ ≥ R... wait √(R²−re²) ≥ 0 so R+|t| ≥ R ⟹ re²/(R+|t|) ≤ 1/R). Then by the γ-gap property: |im s − R| ≥ 1/(16Ĉ₀) or ≥ 1. If |im s| near R: |im s − R| ≤ 1/R. Need 1/R < 1/(16·Ĉ₀(4k+9/2)) i.e. 16·Ĉ₀(4k+9/2) < R — the threshold lemma. Hmm wait, but actually the γ-gap gives clearance |γ − R| for POSITIVE ordinates near R; im s could be negative: |im s| ≈ R ⟹ im s ≈ −R: then |im s − R| ≈ 2R ≥ 1 — the second disjunct, no contradiction needed... wait we need a contradiction in both cases? No: the gap says (clearance) ∨ (≥1). If im s ≈ −R, |im s − R| ≈ 2R > 1 for R > 1 — consistent, no contradiction. But if im s < 0 then |im s − (−R)|... hmm the gap circle is symmetric? The gap property is only about |ρ.im − R|. For a zero with im ≈ −R, there's no contradiction from the gap! Hmm wait — isNontrivialZero_conj: if s is a nontrivial zero with im s < 0, then conj s is a nontrivial zero with im = −im s > 0 ≈ R. Then apply the gap to conj s: |−im s − R| = |im s + R|... hmm no: conj s has im = −(im s) ≈ R. Gap: |(−im s) − R| ≥ 1/(16Ĉ₀) or ≥ 1. And |−im s − R| = ||im s| − R| ≤ 1/R < 1/(16Ĉ₀) by threshold, and < 1. Contradiction either way. So: for s on the circle, if IsNontrivialZero s, let t = |im s| (√(R²−re²) as computed); the zero ρ' = s if im s ≥ 0 else conj s has im ρ' = |im s|. Then |im ρ' − R| = R − |im s| ≤ re²/R ≤ 1/R < min(1, 1/(16Ĉ₀)) by threshold (needs 16Ĉ₀ < R and R > 1). Contradiction with the gap applied to ρ'. **Lemma B (THRESHOLD, k ≥ 4000):** 16·Ĉ₀(4k+9/2) < 4k+5/2 (≤ R). Via Ĉ₀(x) = 0.886·log(x+2) + 0.433·log(log(x+2)) + something? Let me check the C0hat definition in LiSkeleton:736. Let me look at the exact def. From LiSkeleton.lean:736: `def C0hat (t : ℝ) : ℝ :=` — need to see. It's D-056 §2's majorant: probably (2/3)·log((t+2)/(2π)) + ... hmm. Let me grep. Also the design says: "Ĉ₀(16006) ≤ 9.36 (log(16008) ≤ 10 ⟸ 16008 ≤ 2.7182818286^10 ⟸ Real.exp_one_lt_d9 + norm_num pow chain; log 10 ≤ 2.4 ⟸ e^{0.4} ≥ 1.4 = 1+0.4 via Real.add_one_le_exp) + the increment bound Ĉ₀(x) − Ĉ₀(16006) ≤ 0.53·(x−16004)/16006 via log(a/b) ≤ a/b − 1 (Real.log_le_sub_one_of_pos)". Then 16·Ĉ₀(4k+9/2) ≤ 16·(9.36 + 0.53·(4k+9/2−16004)/16006)... and we want this < 4k+5/2. The linear function 16·0.53/16006·(4k) ≈ 0.0021·k grows slower than 4k, and at k = 4000: 16·9.36 ≈ 150 < 16002. So with room. The design says "16·Ĉ₀(4k+9/2)·26 ≤ 4k+2-ish" hmm — the ·26 might be for the critical shell arc bound: 13/R ≤ 1/(32Ĉ₀) ⟺ 13·32·Ĉ₀ ≤ R ⟺ 416·Ĉ₀ ≤ R. Yes! That's the ·26... 13·32 = 416 = 16·26. So the threshold lemma is: 416·Ĉ₀(4k+9/2) ≤ 4k+5/2 (≤ R). That gives both 16Ĉ₀ < R (for the zero-free circle) and 13/R ≤ 1/(32Ĉ₀) (for the critical arcs). Check: 416·9.36 ≈ 3894 at k=4000 vs 16002 ✓ huge slack. Linear growth: Ĉ₀(x) ≈ 1.1·log x; 416·1.1·log(4k) vs 4k: at k=4000, 416·1.1·8.3+... ≈ 4000·... fine, and the slope of LHS ~416·1.1/(4k)·4 ≈ 0.11 at k=4000 decreasing, while RHS slope 4. So holds for all k ≥ 4000 easily. **Lemma C (the tail via zero_tail_inv_sq_le):** tail contribution ≤ 40·A₀·log R per design. Let me redo: tail ≤ (17R/6)·16·A₀·log(2R−1)/(2R−1). log(2R−1) ≤ log(2R) = log 2 + log R ≤ 2 log R (R ≥ 2). And R/(2R−1) ≤ 1 (R ≥ 1). So ≤ (17/6)·16·A₀·2·log R = (272/3)·A₀·log R ≈ 90.7·A₀·log R. The design says ≤ 40·A₀·log R — hmm, 17/6·16 = 45.3, times 2 for the log = 90.7. Or without the log 2: log(2R−1)/(2R−1)·R ≤ log(2R)/(2R−1)·R. Eh, constants don't matter much — I'll use whatever comes out, maybe ≤ 96·A₀·log R. Fine. Wait, actually, one issue: the tail in the tsum_split is ∑' ρ, (if ρ ∈ F then 0 else g ρ) where F = {‖ρ‖ ≤ 2R}. For ρ ∉ F (‖ρ‖ > 2R), g ρ = m·R/(‖ρ‖‖s−ρ‖) ≤ (17/6)·R·m/(1+‖γ‖²) via seriesTerm_norm_le's internals. Hmm — but rather than re-deriving, note g ρ = ‖seriesTerm s ρ‖ (the identity lemma) and seriesTerm_norm_le gives ‖seriesTerm s ρ‖ ≤ (17/6)·‖s‖·m/(1+‖γ‖²) directly for ‖ρ‖ ≥ 2 and 2‖s‖ ≤ ‖ρ‖. ‖s‖ = R. So tail term ≤ (17R/6)·m/(1+‖γ‖²) ≤ (17R/6)·m/(1+im²) = (17R/6)·tailTerm (2R−1) ρ when |γ| > 2R−1 (which holds when ‖ρ‖ > 2R). So the if-zeroed sum ≤ (17R/6)·Σ tailTerm(2R−1) ≤ (17R/6)·16A₀log(2R−1)/(2R−1). **Lemma D (finite part shells):** This is the big one. Σ_{ρ∈F} g ρ where F = {‖ρ‖ ≤ 2R} subtype-finset. Split F by filter into the 5 shells. Each shell: 1. **low** (‖ρ‖ ≤ 3): g ρ = mR/(‖ρ‖‖s−ρ‖), ‖s−ρ‖ ≥ R−‖ρ‖ ≥ R−3. g ρ ≤ m·R/((R−3)·‖ρ‖) = (R/(R−3))·m/‖ρ‖ ≤ 2·m/‖ρ‖ (R ≥ 6) ≤ 2·m(1+1/‖ρ‖)... wait 2/‖ρ‖ ≤ 2(1+1/‖ρ‖) ✓. Sum ≤ 2·lowZeroConst. But careful: lowZeroConst's finset is lowZeros = {‖ρ‖ ≤ 3} (all of them, not just those in F). Since F_low = F.filter(‖ρ‖ ≤ 3) ⊆ lowZeros, sum over F_low ≤ sum over lowZeros by nonneg. Good: ≤ 2·lowZeroConst. This is a CONSTANT (no log R) — absorbed. 2. **inner-low** (3 < ‖ρ‖ ≤ R/2): g ρ ≤ 2m/‖ρ‖ (since ‖s−ρ‖ ≥ R−‖ρ‖ ≥ R/2 ≥ ‖ρ‖... wait R−‖ρ‖ ≥ R/2 ✓ so g ρ ≤ m·R/(‖ρ‖·(R/2)) = 2m/‖ρ‖). Dyadic: for j ≥ 1 with 2^j < ‖ρ‖ ≤ 2^{j+1}, g ≤ 2m/2^j. Zeros: |γ| ≥ ‖ρ‖−1 > 2^j−1 and |γ| ≤ ‖ρ‖ ≤ 2^{j+1}. Two Ncount windows (pos/neg): Ncount(2^j−1, 2^{j+1}] + Ncount(−2^{j+1}, −(2^j−1)] ≤ 2·A₀·(2^j+2)·log(3·2^{j+1}+5). Contribution of shell-j: (2/2^j)·2A₀(2^j+2)log(3·2^{j+1}+5) = 4A₀(1+2/2^j)·log(3·2^{j+1}+5) ≤ 12·A₀·(log(3·2^{j+1}+5)) hmm ≤ 12·A₀·(j·log2 + log(3+5)... let me not precompute; assemble at the end: ≤ Σ_{j=1}^{J} 12·A₀·log(3·2^{j+1}+5) where J = ⌈log₂(R/2)⌉. log(3·2^{j+1}+5) ≤ log(8·2^{j+1}) = (j+4)log 2 ≤ (j+4)·1 hmm log 2 < 1 so ≤ j+4. So per-j ≤ 12A₀(j+4), sum over j ≤ J: 12A₀(J(J+1)/2 + 4J) = O(A₀·J²) = O(A₀(log R)²). Number of dyadic shells: j ranges over ℕ but only finitely many shells contain zeros of F (‖ρ‖ ≤ R/2 ⟹ 2^j < R/2). Handle: define the shells as filter on F with condition 2^j < ‖ρ‖ ≤ 2^{j+1}, j ∈ Finset.range (J+1) for J with 2^J ≥ R/2... or better: sum over j : ℕ but use that shells are empty for 2^j ≥ R/2. Cleanest in Lean: sum over j ∈ Finset.range (J+1) where J = Nat.log 2 ⌊R/2⌋₊ + 1 or similar; show every ρ in inner-low has 2^j < ‖ρ‖ ≤ 2^{j+1} for a unique j (Nat.log 2 ⌊‖ρ‖⌋₊) and j ≤ J. This is getting big. Total estimate: this chunk is probably 800–1200 lines of Lean. That's a LOT for one session. Let me think about how to split. STATE.md says this session is "chunk 3 — the main seriesFun_norm_le_gapCircle". The previous chunk (tail bound) took a full session (031) and was ~500 lines. This chunk is bigger. Given the session protocol (sub-stages end in clean committed states), I should aim for: **Session 032 target:** the full `seriesFun_norm_le_gapCircle` — but if it runs long, natural sub-stops: - chunk 3a: Lemma A (no zeros on circle) + Lemma B (threshold k ≥ 4000) + the norm-identity setup (g ρ = m·R/(‖ρ‖‖s−ρ‖)) + the tsum split + the tail (Lemma C). - chunk 3b: the five shell bounds + assembly. Actually, let me reconsider the assembly. What exactly should the final statement be? Something like: ``` theorem seriesFun_norm_le_gapCircle (hZC : ZeroCountProp) {k : ℕ} (hk : 4000 ≤ k) {R : ℝ} (hR : 4*k+5/2 ≤ R) (hgap : ∀ ρ, IsNontrivialZero ρ → (1/(16*C0hat(4k+9/2))) ≤ |ρ.im - R| ∨ 1 ≤ |ρ.im - R|) {s : ℂ} (hs : ‖s‖ = R) : ‖seriesFun s‖ ≤ C * A0count * (Real.log R)^2 (or similar explicit form) ``` The exact constant doesn't matter — the squeeze only needs O((log R)³) total. Actually for 5e-v-d we need ‖Gentire‖ on the circle ≤ C(log R)³-ish with any constants. The series part is O(A₀·Ĉ₀·log R + A₀(log R)²) = O((log R)³)-ish since Ĉ₀ = O(log R·loglog R). The final Fexpr bound will fold everything. So I should pick a clean explicit bound. Given Ĉ₀(4k+9/2) ≤ Ĉ₀(R+2) (mono, R ≤ 4k+3 ⟹ 4k+9/2 ≤ R+2), and Ĉ₀(x) = (2/3)log(x+2)... let me check C0hat's actual definition. From LiSkeleton.lean:736 — let me look at it. Actually, let me look at C0hat and also think about what form the final bound should take. Let me grep the definition.
Let me check the exact `C0hat` definition and the `ZeroCountProp`/`zeroWindow` API.

Also the zero-free circle lemma. Let me write both now, then compile. One concern: `Real.log_le_sub_one_of_pos : 0 < x → Real.log x ≤ x - 1`. Verify name: I believe it's `Real.log_le_sub_one_of_pos`. In recent Mathlib: `Real.log_le_sub_one_of_pos (hx : 0 < x) : log x ≤ x - 1`. Yes (D-068 design mentions it). For the norm-form: 416 * C0hat(...) where C0hat unfolds to 0.433*log+0.886*loglog+2.9. I'll `unfold C0hat` or `rw [C0hat]`/`show`. C0hat is a def; `simp only [C0hat]` or `unfold C0hat` works (LiBasePoints uses `unfold C0hat`). Now writing the code. I'll append §5 to LiCircleBound.lean.
Clean baseline (27s). Now writing chunk 3a: the threshold lemma + the zero-free circle lemma, appended as §5.

Progress: hC and hC2 now pass. New error at 988: `⊢ 0 ≤ ?m.2659` — a metavariable side goal. That's in `hfin`'s h1: `apply mul_le_mul_of_nonneg_left _ (by norm_num)` then `exact add_le_add_left (mul_le_mul_of_nonneg_left hΔle (by norm_num)) _`. The issue: `mul_le_mul_of_nonneg_left hΔle (by norm_num)` — the (by norm_num) arg is `0 ≤ ?c` where ?c is the multiplier — but the multiplier isn't determined yet (metavariable), so norm_num can't close `0 ≤ ?m.2659`. The multiplier is 0.532: `mul_le_mul_of_nonneg_left hΔle (show (0:ℝ) ≤ 0.532 by norm_num)`. Hmm — but even with `show 0 ≤ 0.532`, the elaborator must unify: mul_le_mul_of_nonneg_left (h : b ≤ a) (hc : 0 ≤ c) : c * b ≤ c * a. Target: 0.532·((y−16000)/16006.5) ≤ 0.532·((y−16000)/16000)?? wait the goal of h1's second part: 9.3564 + 0.532·((y−16000)/16006.5) ≤ 9.3564 + 0.532·((y−16000)/16000). add_le_add_left (h : b ≤ c) (a) : a + b ≤ a + c. So need b ≤ c: 0.532·Δ1 ≤ 0.532·Δ2 — mul_le_mul_of_nonneg_left hΔle (0 ≤ 0.532): but mul_le_mul_of_nonneg_left hΔle gives c·b ≤ c·a where hΔle : Δ1 ≤ Δ2: result c·Δ1 ≤ c·Δ2 ✓ with c := 0.532 — but the elaborator needs to figure c from hc's proof `by norm_num` which has goal `0 ≤ ?c` — metavariable. Fix: `mul_le_mul_of_nonneg_left hΔle (by norm_num : (0:ℝ) ≤ 0.532)` — wait, does that pin it? The ascription `(by norm_num : (0:ℝ) ≤ 0.532)` gives the proof term type 0 ≤ 0.532, so ?c := 0.532 ✓. Actually — banked gotcha: ascribe numerals in such spots. Fix h1: ``` have h1 : 416 * (9.3564 + 0.532 * ((y - 16000) / 16006.5)) ≤ 416 * (9.3564 + 0.532 * ((y - 16000) / 16000)) := by apply mul_le_mul_of_nonneg_left _ (by norm_num : (0:ℝ) ≤ 416) exact add_le_add_left (mul_le_mul_of_nonneg_left hΔle (by norm_num : (0:ℝ) ≤ 0.532)) _ ``` Let me apply.
Metavariable in the un-ascribed multiplier. Pinning it.

`add_le_add_left` in this Mathlib has the argument order swapped vs classic (banked gotcha from session 025: "this Mathlib's add_le_add_left/right are swapped vs classic"). `add_le_add_left (h : b ≤ c) (a)` might be `add_le_add_left (h : a ≤ b) : c + a ≤ c + b` as a CONSTRUCTOR without explicit a — the error shows it produced `x + ?m ≤ y + ?m` meaning the signature is `add_le_add_left : a ≤ b → ∀ (c), c + a ≤ c + b`?? The result type shows `0.532*... + ?m.2676 ≤ 0.532*... + ?m.2676` — so it's a + c ≤ b + c form — i.e., this Mathlib's `add_le_add_left (h : a ≤ b) (c) : a + c ≤ b + c`?? Actually classic: add_le_add_left (h : a ≤ b) (c) : c + a ≤ c + b. The error shows the c on the RIGHT: `x + ?m ≤ y + ?m`. So in this Mathlib, `add_le_add_left h c : a + c ≤ b + c`?? Hmm — the session-025 gotcha said they're swapped. Use `add_le_add_right` instead, or just use `by linarith` / `by gcongr`. Simplest robust: replace with `by gcongr` or provide the inequality via `add_le_add (le_refl _) (...)`. Let me just use: ``` exact add_le_add_left (mul_le_mul_of_nonneg_left hΔle (by norm_num : (0 : ℝ) ≤ 0.532)) (9.3564) ``` Wait — if add_le_add_left h c : a + c ≤ b + c in this Mathlib (swapped), then add_le_add_left h 9.3564 gives 0.532Δ1 + 9.3564 ≤ 0.532Δ2 + 9.3564 — the 9.3564 is on the RIGHT of the sum, but our goal has it on the LEFT: 9.3564 + 0.532Δ1. `add` is commutative but not syntactically. So need add_le_add_right... if swapped, add_le_add_right h c : c + a ≤ c + b. Ugh. Safest: use gcongr: ``` · gcongr exact mul_le_mul_of_nonneg_left hΔle (by norm_num : (0 : ℝ) ≤ 0.532) ``` Hmm gcongr on 416·(9.3564+0.532·Δ1) ≤ 416·(9.3564+0.532·Δ2): gcongr should decompose: 416·_ monotone (needs 0 ≤ 416 side), then 9.3564+_ , then 0.532·_ (0 ≤ 0.532 side). gcongr leaves side goals: 0 ≤ 416? gcongr's pattern for mul_le_mul_of_nonneg_left requires positivity of the factor — it discharges via positivity usually. Let me just restructure h1 to avoid the apply: ``` have h1 : 416 * (9.3564 + 0.532 * ((y - 16000) / 16006.5)) ≤ 416 * (9.3564 + 0.532 * ((y - 16000) / 16000)) := mul_le_mul_of_nonneg_left (add_le_add (le_refl _) (mul_le_mul_of_nonneg_left hΔle (by norm_num : (0 : ℝ) ≤ 0.532))) (by norm_num : (0 : ℝ) ≤ 416) ``` add_le_add (h1 : a ≤ b) (h2 : c ≤ d) : a + c ≤ b + d — unambiguous. a = 9.3564, b = 9.3564 (le_refl), c = 0.532·Δ1, d = 0.532·Δ2 ✓ gives 9.3564 + 0.532Δ1 ≤ 9.3564 + 0.532Δ2 ✓. Also check the next error at 1037 — let me see what that is after fixing. Let me look at line 1037 region. It's probably in not_isNontrivialZero_on_gapCircle. Let me fix h1 first then recompile to see.
This Mathlib's `add_le_add_left` is the swapped form (banked gotcha). Using `add_le_add` instead.

Three errors in `not_isNontrivialZero_on_gapCircle`: 1. Line 1038 (hnormSq): `rw [← Complex.normSq_eq_norm_sq, Complex.normSq_apply]` leaves `s.re*s.re + s.im*s.im = s.re^2 + s.im^2` — normSq_apply gives re*re + im*im form; need `ring` after, or use `Complex.sq_abs`... Fix: add `ring` — wait it's a `have hnormSq : ‖s‖^2 = s.re^2 + s.im^2`: after the rewrites the goal becomes the mul form; add ring. Hmm — actually rw closes by rfl if possible; the residual goal means rfl doesn't hold syntactically. Add `ring`. Wait — but if I add `ring` after rw in the same tactic block: `rw [...]` leaves goal `s.re*s.re + s.im*s.im = s.re^2+s.im^2`? Hmm actually the issue: normSq_apply : normSq z = z.re*z.re + z.im*z.im. So after rw, goal `s.re*s.re + s.im*s.im = s.re^2 + s.im^2` — close by `ring`. ✓ 2. Line 1083/1085 (hρ'im): `abs_of_nonneg him : |s.im| = s.im` but goal is `s.im = |s.im|` — use `.symm`. Since the goal is ρ'.im = |s.im| and in the if_pos branch ρ'.im = s.im: goal `s.im = |s.im|`: `(abs_of_nonneg him).symm`. Similarly `abs_of_neg ... .symm`. Wait line 1085: after `rw [if_neg him, Complex.conj_im]` goal: `-s.im = |s.im|`: `(abs_of_neg (lt_of_not_ge him)).symm` : -s.im = |s.im| ✓. 3. Line 1090 (hdist): `abs_of_nonpos (by linarith [ht_le])` — the goal there is `|(|s.im|) − R| = R − |s.im|`: abs_of_nonpos needs `|s.im| − R ≤ 0`: from ht_le: |s.im| ≤ R: |s.im| − R ≤ 0 ✓ linarith should do... the error is "linarith failed" at 1090:22 — the `by linarith [ht_le]` inside abs_of_nonpos. ht_le : |s.im| ≤ R. Goal: |s.im| − R ≤ 0. linarith [ht_le] should close! Unless the goal isn't that — maybe elaboration of `abs_of_nonpos` target: `|(|s.im| : ℝ) - R| = R - |s.im|`: abs_of_nonpos (h : a ≤ 0) : |a| = -a. With a := |s.im| − R: |a| = -a = R − |s.im| hmm -(|s.im| − R) = R − |s.im| — not syntactically equal! The expected RHS is R − |s.im| and abs_of_nonpos gives −(|s.im| − R). These are ring-equal but not definally... actually `neg_sub` : -(a-b) = b-a is a theorem, but as a `have` type ascription mismatch — the `show` form: I wrote `hdist : |(|s.im| : ℝ) - R| = R - |s.im| := abs_of_nonpos (by linarith [ht_le])`. abs_of_nonpos gives |x| = -x; expected |x| = R − |s.im| with x = |s.im| − R: -x = R − |s.im|: needs `sub_neg_eq_add`... no: −(|s.im|−R) = R−|s.im| by ring/abel — not rfl? Actually −(a−b) unfolds to −a+b? `neg_sub a b : -(a - b) = b - a` is a simp lemma, defeq? -(a−b) is Neg.neg (HSub.hSub a b); b − a is HSub.hSub b a — NOT defeq. So type mismatch... but the reported error is linarith FAILED — hmm, maybe the elaborator unified a := |s.im| − R fine and the remaining proof obligation... the `by linarith [ht_le]` goal: |s.im| − R ≤ 0. Wait — but abs_of_nonpos's hypothesis is `a ≤ 0`, that's |s.im| − R ≤ 0, linarith [ht_le] closes. Unless the elaborator picked a weird a... The error at 1090:22 is "linarith failed to find a contradiction" with context not fully shown. Hmm, possibly the ascribed type `|(|s.im| : ℝ) - R|` — the `(|s.im| : ℝ)` ascription is odd (s.im is already ℝ). Actually maybe the issue is the goal at that point: hdist's statement uses `|(|s.im| : ℝ) - R|` — with the extra coercion `(|s.im| : ℝ)`... |s.im| is ℝ already, so (↑|s.im| − R) with a coercion ↑:ℝ→ℝ (identity)? The ascription `(|s.im| : ℝ)` may insert a coe. Then abs_of_nonpos sees `↑|s.im| − R ≤ 0` and linarith should still... with a coe ℕ? no. Let me just rewrite hdist cleanly: ``` have hdist : |s.im - R| = R - |s.im| := by rw [abs_of_nonpos (by linarith [ht_le] : s.im - R ≤ 0)] ring ``` Wait hgap' is about `|ρ'.im − R|` with ρ'.im = |s.im| — after rw [hρ'im] at hgap', it's `|(|s.im|) − R|` — hmm the rewrite substitutes ρ'.im := |s.im| giving `||s.im| − R|`. So hdist must match `||s.im| − R| = R − |s.im|`. Note `||s.im| − R|`: the inner |s.im| is ℝ-abs, outer too. Statement: `have hdist : |(|s.im|) - R| = R - |s.im|` — hmm the parentheses. Let me write `have hdist : |(|s.im| : ℝ) - R| = R - |s.im|`. The coercion `(|s.im| : ℝ)` — no coercion needed since |s.im| : ℝ. It's fine but let me drop it: `|(|s.im|) - R|`... Lean parses |x| as abs; `||s.im| − R|` needs the bars: write `|(|s.im| - R)|`? That's |(|s.im| − R)| hmm ambiguity: `|(|s.im| - R)|` = abs of (|s.im| − R) ✓. But actually what does hgap' look like after rw [hρ'im]? hgap ρ' : 1/(16Ĉ) ≤ |ρ'.im − R| ∨ ... — rw [hρ'im] at hgap' replaces ρ'.im with |s.im|: `||s.im| − R|`... in Lean's notation `|(|s.im| : ℝ)...` ugh. Simplest: avoid the rewrite fragility — set t := |s.im| first, prove hρ'im : ρ'.im = t, and work with t throughout: Actually cleaner: don't rw at hgap'; instead rcases hgap ρ' hρ'z, rewrite hρ'im inside each case. Or: ``` have hgap' := hgap ρ' hρ'z rw [hρ'im] at hgap' ``` The term hgap' : 1/(16·C0hat ...) ≤ |(|s.im|) - R| ∨ 1 ≤ |(|s.im|) - R|. Wait — no: ρ'.im is `Complex.im ρ'` — hρ'im : ρ'.im = |s.im| rewrites occurrences of ρ'.im... but in hgap' the term is ρ'.im where ρ' is the if-then-else — after `rw [hρ'im]`, becomes |s.im| — fine. Then hdist : |(|s.im| : ℝ) - R| = R - |s.im|. To prove robustly: ``` have hle : (|s.im| : ℝ) - R ≤ 0 := by linarith [ht_le] have hdist : |(|s.im| : ℝ) - R| = R - |s.im| := by rw [abs_of_nonpos hle] ring ``` abs_of_nonpos hle : |(|s.im| − R)| = −(|s.im| − R); then ring: −(|s.im|−R) = R−|s.im| ✓. But the STATEMENT's LHS `|(|s.im| : ℝ) - R|` must parse the same as hgap's. Since s.im : ℝ, |s.im| : ℝ, and (|s.im| : ℝ) is just ascription — should be syntactically |s.im| − R inside outer bars. hgap' after rw: |↑|s.im| − R|? Is there a coercion? |s.im| : ℝ, and the abs in hgap is on ℝ (ρ.im : ℝ): |ρ'.im − R| with ρ'.im : ℝ — after rw hρ'im: ||s.im| − R| no coercions. My hdist with (|s.im| : ℝ) ascription — the ascription adds no term, so syntactic match should hold. But then `rw [hdist] at hgap'` — matching should work. Then after rcases: case 1: 1/(16Ĉ) ≤ R−|s.im| contradicts hsmall (R−|s.im| < 1/(16Ĉ)) ✓ linarith; case 2: 1 ≤ R−|s.im| contradicts hsmall1 ✓. Also error 1090 was at hdist — fixed by the restructure. Additionally hsmall's one_div_lt_one_div_of_lt and hsmall1's one_div_lt_one_of_lt_one might not exist by those names. Let me replace with robust forms: - h1 : 1/R < 1/(16Ĉ): since 0 < 16Ĉ < R: `one_div_lt_one_div_of_lt (h16Ĉpos : 0 < 16*Ĉ) h16 : 1/R < 1/(16Ĉ)` — signature: one_div_lt_one_div_of_lt (ha : 0 < a) (h : a < b) : 1/b < 1/a. So one_div_lt_one_div_of_lt (show 0 < 16*Ĉ ...) h16 : 1/R < 1/(16·Ĉ) ✓ (a = 16Ĉ, b = R). ✓ exists in Mathlib (one_div_lt_one_div_of_lt). - hsmall1: 1/R < 1 for R > 1: `one_div_lt_one_of_lt_one`?? Unsure. Use: (div_lt_one (by linarith [hR1] : (0:ℝ) < R)).mpr (by linarith [hR1] : 1 < R)... div_lt_one (hb : 0 < b) : a/b < 1 ↔ a < b ✓. So `have h1 : 1/R < 1 := (div_lt_one hR1pos).mpr hR1` — wait 1 < R gives 1/R < 1 ✓ (a=1, b=R). Hmm div_lt_one needs a/b form: 1/R ✓. Let me fix all three spots.
Fixing the three errors in the zero-free circle proof: `ring` after normSq rewrites, `.symm` on the abs lemmas, and a cleaner `hdist`.

So `hsum_img := (Finset.sum_image (fun x _ y _ h => Subtype.val_injective h)).symm`. 2. **Line 1247 (h2)**: `abs_neg M : |-M| = |M|` — expected |-M| = M. Fix: `abs_of_nonneg` after: `by rw [abs_neg, abs_of_nonneg (by linarith [hM1'] : (0:ℝ) ≤ M)]`. So h2 : |-M| = M := by rw [abs_neg]; exact abs_of_nonneg (by linarith [hM1']). 3. **Line 1256 (h6)**: `|b| ≤ max |a| |(|b|)|` — the goal has `|(|b|)|` (abs of abs) because I did `rw [← h5]` where h5 : |b| = b — that rewrote b to |b| everywhere including inside the existing |b|. Goal was `(b:ℝ) ≤ max |a| |b|`; rw [← h5] turned it into `|b| ≤ max |a| |(|b|)|`. Bad. Instead: `have h6 : (b:ℝ) ≤ max |a| |b| := le_trans (le_abs_self b) (le_max_right _ _)`. Clean. 4. **Line 1401**: `rw [h1]` then `field_simp; ring` — the "No goals" — h1's proof: `field_simp; ring` — field_simp closed it, ring errored "No goals". Wait — error at 1401:6 "No goals to be solved" — that's the `ring` after `field_simp` succeeded. Remove the ring? But which line is 1401... it's h1 in hbound: `field_simp; ring`. If field_simp closes, drop ring. But it might be fragile — replace with just `ring`? The identity: 17*R/6*(16*A0count*log(2R−1)/(2R−1)) = (17/6)*16*A0count*(R/(2R−1))*log(2R−1). With divisions — field_simp then ring is the standard pattern; if field_simp closed it alone, great — but "No goals" error means field_simp DID close and ring failed. So remove `ring`. But careful: maybe field_simp left no goals because it solved it via rfl-match. Remove ring. Actually wait — error 1401 might be the `ring` in the calc step `_ = (272/3) * ... := by ring`? No — that would be needed. Line numbers: 1401 in hbound... h1's field_simp;ring is around there. Let me just fix: `:= by field_simp` — but if field_simp leaves a goal, error. Safer: `:= by rw [mul_div_assoc]; ring`? Hmm the forms: LHS 17*R/6*(16*A0*L/(2R−1)) — treat 17*R/6 as (17/6)*R: LHS = (17/6)*R*16*A0*L/(2R−1); RHS = (17/6)*16*A0*(R/(2R−1))*L = (17/6)*16*A0*R*L/(2R−1). Same by ring_nf handling division? `ring` handles division in fields: goal is an identity in the field ℝ with div — `ring` should close it directly (ring normalizes rat funcs). Just use `by ring`. Hmm — but ring with Real.log(2R−1) as an atom and (2R−1) as an atom: the identity is rational in the atoms {R, A0count, Real.log (2*R−1), (2*R−1)...} — but (2*R−1) appears both as atom (inside log) and as algebraic expression 2R−1 (in the divisor). ring treats Real.log(2*R−1) as an opaque atom whose argument is normalized to 2*R−1 ✓ and the divisor 2*R−1 normalizes to the same ✓. So `ring` alone should work. Use `:= by ring`. 5. **Line 1406 (h2's first apply)**: `apply mul_le_mul_of_nonneg_left _ hA0` — the goal at that point: after `apply mul_le_mul`, first goal is `17/6*16*A0count*(R/(2R−1)) ≤ 17/6*16*A0count*1` — my apply chain tried to peel factors one at a time but mul_le_mul_of_nonneg_left only strips ONE left factor A0count, leaving `17/6*16*(R/(2R−1)) ≤ 17/6*16*1` mismatch — the apply failed because the goal has THREE left factors before A0count? Wait goal: `17 / 6 * 16 * A0count * (R / (2 * R - 1)) ≤ 17 / 6 * 16 * A0count * 1`. mul_le_mul_of_nonneg_left (h : b ≤ a) (hc : 0 ≤ c) : c*b ≤ c*a. Unify c*? = 17/6*16*A0count*(R/(2R−1)): with b := R/(2R−1), a := 1: c must be 17/6*16*A0count — the apply `mul_le_mul_of_nonneg_left _ hA0` forces c := A0count (from hA0 : 0 ≤ A0count) — mismatch since the head constant is 17/6*16*A0count. Fix: `apply mul_le_mul_of_nonneg_left hR21 (by positivity : (0:ℝ) ≤ 17/6*16*A0count)` — one step: hR21 : R/(2R−1) ≤ 1 ✓ c := 17/6*16*A0count, positivity should handle A0count? NO — banked gotcha: positivity can't see through Classical.choose defs (A0count). Use explicit: mul_nonneg (mul_nonneg (by norm_num) (by norm_num)) hA0... (0 ≤ 17/6*16*A0count): = mul_nonneg (by norm_num : (0:ℝ) ≤ 17/6*16) hA0. So: ``` · exact mul_le_mul_of_nonneg_left hR21 (mul_nonneg (by norm_num : (0:ℝ) ≤ 17/6*16) hA0) ``` ✓. Also check the mul_le_mul's other args in h2: mul_le_mul (hab : a≤b) (hcd : c≤d) (hc : 0≤c) (hb : 0≤b) : a*c ≤ b*d with a := 17/6*16*A0*(R/(2R−1)), b := 17/6*16*A0*1, c := log(2R−1), d := 2·logR. hc : 0 ≤ log(2R−1): log(2R−1) ≥ log R... hmm I passed hlogRnn (0 ≤ log R) — wrong: need 0 ≤ Real.log (2*R−1). log(2R−1) ≥ log R ≥ 9? 2R−1 ≥ R ✓ so log(2R−1) ≥ log R ≥ 9 ≥ 0. Fix: provide `by have := hlog2R... ` — actually simpler: Real.log_nonneg (by linarith [hRpos] : (1:ℝ) ≤ 2*R−1). And hb : 0 ≤ 17/6*16*A0*1 — I passed mul_nonneg ... (0 ≤ R/(2R−1)) — wrong again: hb should be 0 ≤ b = 17/6*16*A0count*1. Fix: mul_nonneg (mul_nonneg (by norm_num) hA0) one_pos.le. Let me rewrite the h2 block: ``` have hlog21nn : (0:ℝ) ≤ Real.log (2*R-1) := Real.log_nonneg (by linarith [hRpos]) have h2 : (17 / 6 : ℝ) * 16 * A0count * (R / (2 * R - 1)) * Real.log (2 * R - 1) ≤ (17 / 6) * 16 * A0count * 1 * (2 * Real.log R) := mul_le_mul (mul_le_mul_of_nonneg_left hR21 (mul_nonneg (by norm_num : (0:ℝ) ≤ 17/6*16) hA0)) hlog2R hlog21nn (mul_nonneg (mul_nonneg (by norm_num : (0:ℝ) ≤ 17/6*16) hA0) one_pos.le) ``` Wait — mul_le_mul signature in this Mathlib (session-025 gotcha about swapped add versions — mul_le_mul is standard: mul_le_mul (hab : a ≤ b) (hcd : c ≤ d) (hc : 0 ≤ c) (hb : 0 ≤ b) : a * c ≤ b * d ✓ as I used in fiber_tail... I used mul_le_mul hfac1 hlogle hLnn (div_nonneg ...) in zero_tail_inv_sq_le ✓ same pattern). Let me apply all fixes.
Four fixes: `sum_image` direction, `abs_neg` form, the `rw [← h5]` self-nesting, and the `mul_le_mul` factor alignment in `hbound`.

The sum_image issue persists. The problem: `Finset.sum_image (h : ∀ x ∈ s, ∀ y ∈ s, f x = f y → x = y) : ∑ x ∈ s.image f, g x = ∑ x ∈ s, g (f x)`. With g := fun z => (zeroMult z : ℝ): the RHS is `∑ x ∈ s, g (Subtype.val x)` = `∑ x ∈ s, (zeroMult ↑x : ℝ)`. Our LHS goal: `∑ ρ ∈ FS, ↑(zeroMult ↑ρ)`. These should match... but the elaborator's ?m.495 is a metavariable because g is implicit and not determined by the injectivity proof. The .symm version: `∑ x ∈ s, g (f x) = ∑ x ∈ s.image f, g x` — expected type matches structurally but g is still a metavariable — unification with the expected type should fix g... The error says "has type ∑ x ∈ ?m.497, ?m.495 ↑x = ∑ x ∈ Finset.image Subtype.val ?m.497, ?m.495 x but expected ∑ ρ ∈ FS, ↑(zeroMult ↑ρ) = ..." — the LHS ?m.495 ↑x should unify with ↑(zeroMult ↑ρ): ?m.495 := fun z => ↑(zeroMult z) — that's a higher-order unification (HOU) — the banked gotcha: "AnalyticAt.comp / Ncount_add_of_le HOU: pin the implicit endpoints". Pin g explicitly: ``` (Finset.sum_image (g := fun z : ℂ => (zeroMult z : ℝ)) (fun x _ y _ h => Subtype.val_injective h)).symm ``` Hmm — Finset.sum_image's signature: `theorem Finset.sum_image [DecidableEq β] {s : Finset α} {f : α → β} {g : β → M} (h : ∀ x ∈ s, ∀ y ∈ s, f x = f y → x = y) : ∑ x ∈ s.image f, g x = ∑ x ∈ s, g (f x)`. g is implicit — pin (g := ...). Also f := Subtype.val — inferable from the injectivity proof? Subtype.val_injective : Injective Subtype.val — the lambda (fun x _ y _ h => Subtype.val_injective h) has type ∀ x ∈ s, ∀ y ∈ s, Subtype.val x = Subtype.val y → x = y — pins f ✓. Pin g too.
HOU issue with the implicit summand — pin `g` explicitly (banked gotcha).

Found it: `Finset.sum_image [DecidableEq β] {s : Finset α} {g : α → β} : Set.InjOn g s → ∑ x ∈ s.image g, f x = ∑ x ∈ s, f (g x)` — the summand `f` is an EXPLICIT argument? No — looking at prod_image: `{s : Finset κ} {g : κ → ι} : Set.InjOn g s → ∏ x ∈ s.image g, f x = ...` — f is a variable from the section (f : ι → M presumably auto-bound). So `Finset.sum_image (h : Set.InjOn Subtype.val s)` with f implicit/section-level. In term mode, `Finset.sum_image (h : Set.InjOn Subtype.val FS) : ∑ x ∈ FS.image Subtype.val, ?f x = ∑ x ∈ FS, ?f (Subtype.val x)`. So the correct usage: `Finset.sum_image (fun x _ y _ h => Subtype.val_injective h)` — the lambda has type ∀ x ∈ FS, ∀ y ∈ FS, val x = val y → x = y which IS Set.InjOn val FS ✓ (that's what session 031 used in a rw — worked). The issue in my case is only the HOU for ?f in term position with ascription. The injOn proof pins g := Subtype.val ✓, but ?f needs the expected type. The ascription IS the expected type... The error message showed my (g := ...) got misassigned — because sum_image's implicit g is the IMAGE function (κ → ι), and my `g := fun z : ℂ => (zeroMult z : ℝ)` got assigned to it! The summand f is auto-bound implicit — pin via (f := fun z : ℂ => (zeroMult z : ℝ)): ``` (Finset.sum_image (f := fun z : ℂ => (zeroMult z : ℝ)) (fun x _ y _ h => Subtype.val_injective h)).symm ``` That should work: f is the summand (ι → M with ι = ℂ here). Let me apply.
`sum_image`'s implicit `g` is the image function; the summand `f` is auto-bound. Pin `f` instead.

3b committed (727f656). Now 3c: the five shell bounds + assembly. Let me plan the shell lemmas concretely. Setup for all shells: - k : ℕ, hk : 4000 ≤ k - R : ℝ, hRlo : 4k+5/2 ≤ R, hRhi : R ≤ 4k+3 - hgap : the ordinate clearance property - s : ℂ, hs : ‖s‖ = R - Derived: hsz : ¬IsNontrivialZero s (3a), hth := gapCircle_threshold hk, hĈ2 : 2 ≤ C0hat(4k+9/2), hR : 16002 ≤ R (from 4·4000+2.5), hlogR : 9 ≤ log R. The finite part F := circleZeros R. g ρ := ‖seriesTerm s ρ‖. Shell predicates (as filters on F): - P1 ρ := ‖(ρ:ℂ)‖ ≤ 3 - P2 ρ := ‖(ρ:ℂ)‖ ≤ R/2 - P3 ρ := ‖(ρ:ℂ)‖ ≤ R−2 - P4 ρ := ‖(ρ:ℂ)‖ < R+2 Partition: F.filter P1 / F.filter (¬P1 ∧ P2) / F.filter (¬P2 ∧ P3) / F.filter (¬P3 ∧ P4) / F.filter ¬P4. Wait — for the shells to match the design: - low: P1 = ‖ρ‖ ≤ 3 - inlo: ¬P1 ∧ P2: 3 < ‖ρ‖ ≤ R/2 ✓ - inhi: ¬P2 ∧ P3: R/2 < ‖ρ‖ ≤ R−2 ✓ - crit: ¬P3 ∧ P4: R−2 < ‖ρ‖ < R+2 ✓ - up: ¬P4: R+2 ≤ ‖ρ‖ ✓ And the sum: Σ_F g = Σ_{F.filter P1} + Σ_{F.filter (¬P1∧P2)} + ... via iterated Finset.sum_filter_add_sum_filter_not: Σ_F g = Σ_{F.filter P1} g + Σ_{F.filter ¬P1} g Σ_{F.filter ¬P1} g = Σ_{(F.filter ¬P1).filter P2} g + Σ_{(F.filter ¬P1).filter ¬P2} g and (F.filter ¬P1).filter P2 = F.filter (fun ρ => ¬P1 ρ ∧ P2 ρ) via Finset.filter_filter (filter P2 (filter ¬P1 F) = filter (fun a => ¬P1 a ∧ P2 a) F — check Finset.filter_filter's form: filter p (filter q s) = filter (fun a => q a ∧ p a) s. So (F.filter ¬P1).filter P2 = F.filter (¬P1 ∧ P2) ✓.) So the assembly is mechanical. Each shell bound is a standalone lemma over an explicit filter-finset: **Shell low**: `shell_low : ∑ ρ ∈ F.filter (fun ρ => ‖(ρ:ℂ)‖ ≤ 3), g ρ ≤ 2 * lowZeroConst` Per element: g ρ = m·(R/(‖ρ‖·‖s−ρ‖)) (seriesTerm_norm_eq_div) ≤ 2m(1+1/‖ρ‖): - ‖s−ρ‖ ≥ R − ‖ρ‖ ≥ R−3: ‖s−ρ‖ ≥ |‖s‖−‖ρ‖| = R−‖ρ‖ (abs_norm_sub_norm_le : |‖a‖−‖b‖| ≤ ‖a−b‖; s−ρ: ‖s‖−‖ρ‖ could be ≥ 0: R ≥ 3 ≥ ‖ρ‖ ✓ so |R−‖ρ‖| = R−‖ρ‖). - m·R/(‖ρ‖·‖s−ρ‖) ≤ m·R/(‖ρ‖·(R−3)): need ‖s−ρ‖ ≥ R−3 > 0 (R ≥ 16002) ✓ div_le_div with the product: m·R/(‖ρ‖·‖s−ρ‖) ≤ m·R/(‖ρ‖·(R−3)) ⟸ ‖ρ‖·‖s−ρ‖ ≥ ‖ρ‖·(R−3) (‖ρ‖ > 0, ‖s−ρ‖ ≥ R−3) ⟹ 1/(‖ρ‖‖s−ρ‖) ≤ 1/(‖ρ‖(R−3)) ⟹ times mR ≥ 0.

Structure in Lean per dyadic family — I'll prove a generic per-family lemma? The three dyadic families share: fiberwise decomposition, per-fiber count brick, per-fiber term bound, the j+4 log bound, J-bound. But the dyad variable differs (‖ρ‖, R−‖ρ‖, ‖ρ‖−R). A fully generic lemma would need the dyad as a parameter with hypotheses linking term bounds and counts — doable but the hypothesis list gets long. Given time, let me do ONE generic dyadic-shell lemma: ``` lemma dyadic_family_le (FS : Finset {ρ // IsNontrivialZero ρ}) (d : {ρ // IsNontrivialZero ρ} → ℝ) (J : ℕ) (C₁ : ℝ) -- term-bound constant: g ρ ≤ C₁·m/2^{j(ρ)} where j = Nat.log 2 ⌊d ρ⌋₊ (hd : ∀ ρ ∈ FS, 2 ≤ d ρ ∧ d ρ < R') -- d range (hterm : ∀ ρ ∈ FS, g ρ ≤ C₁ * (zeroMult ρ : ℝ) / (2:ℝ)^(Nat.log 2 ⌊d ρ⌋₊)) (hcount : ∀ j ∈ Ico 1 (J+1), ∀ (per-j count bound)) ``` Hmm — the count brick per shell j needs the a,b,c which depend on the family. Parameterize by giving the count bound as a hypothesis function: ``` (hcount : ∀ j : ℕ, ∑ ρ ∈ FS.filter (fun ρ => Nat.log 2 ⌊d ρ⌋₊ = j), (zeroMult (ρ:ℂ):ℝ) ≤ cnt j) ``` and then conclude Σ_{FS} g ≤ Σ_{j∈Ico 1 (J+1)} C₁/2^j·cnt j... plus needing the fiber-cover fact: every ρ ∈ FS has j(ρ) ∈ Ico 1 (J+1). Then per family, instantiate: d, J, C₁, cnt with the brick providing hcount. The generic lemma: Σ_{FS} g ≤ Σ_{FS} C₁·m/2^{j(ρ)} [sum_le_sum via hterm] = Σ_{j∈image j(·)} Σ_{fiber} C₁·m/2^j [fiberwise] = Σ_j (C₁/2^j)·(Σ_{fiber} m) [sum_congr + mul_sum] ≤ Σ_{j∈image} (C₁/2^j)·cnt j [hcount per j] ≤ Σ_{j∈Ico 1 (J+1)} (C₁/2^j)·cnt j [image ⊆ Ico, terms ≥ 0] then per-family closed form. For the fiberwise step, check if Finset.sum_fiberwise exists. Let me grep Mathlib.

The sum_fiberwise_of_maps_to gives `∑ y ∈ t, ∑ x ∈ s.filter..., f x = ∑ x ∈ s, f x` — the RHS-first orientation. I need `.symm`. And the f metavariable — pin via ascription or (f := ...). The signature: prod_fiberwise_of_maps_to {g : ι → κ} (h : ∀ i ∈ s, g i ∈ t) (f : ι → M) : ... — f explicit ✓ so pass f explicitly: `Finset.sum_fiberwise_of_maps_to hmaps (fun ρ => C₁ * (zeroMult (ρ:ℂ):ℝ) / (2:ℝ)^(Nat.log 2 ⌊d ρ⌋₊))` — wait but h2's statement has the equality in the direction ∑_{FS} = ∑_{j∈Ico}: so (....).symm.
Orientation + explicit summand.

Only a linter warning (hcnt now unused since I removed the subset step). The build succeeded otherwise (no errors). Let me fix the warning by removing the hcnt hypothesis... wait — is it really unused? I removed the `sum_le_sum_of_subset_of_nonneg h5` step which used hcnt. Now hcnt is genuinely unused. But wait — the per-fiber count bounds (hcount j) should be ≥ 0 anyway since LHS ≥ 0... the lemma doesn't need hcnt. Remove it. Actually — keep the API clean: remove `(hcnt : ∀ j : ℕ, (0 : ℝ) ≤ cnt j)`.
Clean except an unused-variable warning — removing `hcnt` from the signature.

Banked gotcha: pin the binder: `fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ...`. Hmm — but in dyadic_family_le the filter lambdas are `fun ρ => Nat.log 2 ⌊d ρ⌋₊ = j` — d application pins ρ to the subtype ✓ no coercion issue THERE. But when I INSTANTIATE d := fun ρ => ‖(ρ:ℂ)‖ and write hcount's filter as `FS.filter (fun ρ => Nat.log 2 ⌊‖(ρ:ℂ)‖⌋₊ = j)`, the elaborator must see the filter lambdas as SYNTACTICALLY equal: dyadic_family_le's internal filter is on `fun ρ => Nat.log 2 ⌊d ρ⌋₊ = j` with d substituted — `⌊d ρ⌋₊` = `⌊(fun ρ => ‖(ρ:ℂ)‖) ρ⌋₊` = beta `⌊‖(ρ:ℂ)‖⌋₊` — should be defeq, but for the hcount hypothesis application the elaborator needs to unify the filter sets — with `classical` and defeq it should work if I state hcount's lambda identically: `fun ρ => Nat.log 2 ⌊(fun ρ => ‖(ρ:ℂ)‖) ρ⌋₊ = j`... The application `dyadic_family_le FS (fun ρ => ‖(ρ:ℂ)‖) J _ 2 cnt hC1 hdj hterm hcount` — the hcount's expected type: ∀ j, ∑ ρ ∈ FS.filter (fun ρ => Nat.log 2 ⌊(d) ρ⌋₊ = j), ... ≤ cnt j with d := the lambda — beta-reduced during unification ✓ my stated hcount uses ⌊‖(ρ:ℂ)‖⌋₊ directly — defeq ✓. BUT the lambda binder ambiguity strikes again: in MY hcount statement `fun ρ => Nat.log 2 ⌊‖(ρ:ℂ)‖⌋₊ = j` — the coercion ‖(ρ:ℂ)‖ — the expected type from dyadic_family_le's unification pins ρ : subtype ✓ — since hcount is APPLIED to a known expected type, elaboration is fine. But if hcount is a standalone `have` with ascribed type, I must pin the binder: `fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ...` — then unification with the expected type needs defeq between `fun ρ : ST => Nat.log 2 ⌊‖(ρ:ℂ)‖⌋₊ = j` and `fun ρ => Nat.log 2 ⌊d ρ⌋₊ = j` — beta + coe ✓ fine. The brick application per j (with hj : j ∈ Ico): a := 2^j−1, b := 2^{j+1}, c := 2^j−1: - hM1 : 1 ≤ max (2^j−1) (2^j−1) = 2^j−1 ⟺ 2 ≤ 2^j ⟺ j ≥ 1 ✓. - hMb : max ... = 2^j−1 ≤ 2^{j+1} ✓. - hsub : ∀ ρ ∈ FS.filter (jf · = j), a ≤ |γ| ∧ |γ| ≤ b ∧ c ≤ |γ|: per element: jf ρ = j ⟹ 2^j ≤ ‖ρ‖ (as before) and ‖ρ‖ < 2^{j+1} (Nat.lt_pow_succ_log_self + floor+1): ``` have hup : ‖(ρ:ℂ)‖ < (2:ℝ)^(j+1) := by have h1 : ⌊‖(ρ:ℂ)‖⌋₊ < 2 ^ (Nat.log 2 ⌊‖(ρ:ℂ)‖⌋₊ + 1) := Nat.lt_pow_succ_log_self (by norm_num) _ rw [hρj] at h1 -- hρj : Nat.log 2 ⌊‖ρ‖⌋₊ = j have h2 : ⌊‖(ρ:ℂ)‖⌋₊ + 1 ≤ 2 ^ (j + 1) := h1 have h3 : ‖(ρ:ℂ)‖ < (⌊‖(ρ:ℂ)‖⌋₊ : ℝ) + 1 := Nat.lt_floor_add_one _ have h4 : ((⌊‖(ρ:ℂ)‖⌋₊ + 1 : ℕ) : ℝ) ≤ ((2 ^ (j + 1) : ℕ) : ℝ) := by exact_mod_cast h2 push_cast at h4 -- h4 : (⌊‖ρ‖⌋₊ : ℝ) + 1 ≤ (2:ℝ)^(j+1) linarith [h3, h4] ``` hmm h4's cast: ((2^(j+1) : ℕ) : ℝ) = (2:ℝ)^(j+1): push_cast at h4 gives (⌊‖ρ‖⌋₊:ℝ)+1 ≤ (2:ℝ)^(j+1) ✓.

Errors: 1. `lt_of_not_le` doesn't exist — use `lt_of_not_ge` (the standard name) or `not_le.mp`. Fix all three occurrences → `lt_of_not_ge`. 2. `Nat.le_floor_iff` rewrite failed: goal is `3 ≤ ⌊‖↑ρ‖⌋₊` in MIXED ℕ/ℝ — the `3` here is `(3:ℕ)`? The goal: `(3:ℕ) ≤ ⌊‖ρ‖⌋₊` — wait hfl3 : (3:ℕ) ≤ ⌊‖ρ‖⌋₊ — the have statement was `have hfl3 : (3 : ℕ) ≤ ⌊‖(ρ : ℂ)‖⌋₊` but the goal shows `3 ≤ ⌊‖↑ρ‖⌋₊` where 3 is ℕ-literal. My rw [Nat.le_floor_iff ...] — Nat.le_floor_iff : n ≤ ⌊x⌋₊ ↔ (n:ℝ) ≤ x where n : ℕ. The rewrite pattern ?m ≤ ⌊?m2⌋₊ — the error shows pattern `?m.260 ≤ ⌊3⌋₊` — the elaborator read my (0:ℝ) ≤ 3 ascription wrong: I wrote `Nat.le_floor_iff (by norm_num : (0 : ℝ) ≤ 3)` — hmm the iff is `Nat.le_floor_iff (hx : 0 ≤ x) : n ≤ ⌊x⌋₊ ↔ (n : ℝ) ≤ x` — the (0 ≤ x) pin determines x, but I passed (0:ℝ) ≤ 3 which sets x := 3?? NO — x should be ‖ρ‖! The hypothesis is about the REAL argument: Nat.le_floor_iff (hx : 0 ≤ x)... wait what's the actual signature? `Nat.le_floor_iff (hx : 0 ≤ x) : n ≤ ⌊x⌋₊ ↔ (n : ℝ) ≤ x`. So I should pass (0 ≤ ‖ρ‖): `Nat.le_floor_iff (norm_nonneg _)`. My ascription (0:ℝ) ≤ 3 pinned x := 3 — wrong. Fix: `rw [Nat.le_floor_iff (norm_nonneg _)]` then `exact hρ3'.le`. Hmm wait — the goal after the failed rw is still `3 ≤ ⌊‖↑ρ‖⌋₊` — with the correct iff the goal becomes `(3:ℝ) ≤ ‖ρ‖` — hρ3'.le : 3 ≤ ‖ρ‖ ✓ — but there's a cast: ((3:ℕ):ℝ) ≤ ‖ρ‖ — exact_mod_cast might be needed: hρ3'.le : (3:ℝ) ≤ ‖ρ‖ (from lt_of_not_ge hρ3 : 3 < ‖ρ‖ — the 3 there is ℝ since ≤ 3 with ‖ρ‖ : ℝ). The iff gives ((3:ℕ):ℝ) ≤ ‖↑ρ‖ — push_cast or exact_mod_cast hρ3'.le. Let me: `rw [Nat.le_floor_iff (norm_nonneg _)]; exact_mod_cast hρ3'.le`. 3. Line 1734 "No goals to be solved" — the h2 in hterm (R/(‖ρ‖·(R/2)) = 2/‖ρ‖ via field_simp; ring) — field_simp closed it, ring errors. Remove ring there. 4. Line 1778: `rw [← hρj] at h1` — h1 : (2:ℕ)^Nat.log... wait: h1 := Nat.pow_log_le_self 2 hfl : 2 ^ Nat.log 2 ⌊‖ρ‖⌋₊ ≤ ⌊‖ρ‖⌋₊ (ℕ inequality). I want to rewrite the Nat.log to j: rw [← hρj] — hρj : Nat.log 2 ⌊‖ρ‖⌋₊ = j, so ← hρj rewrites j → Nat.log... — the error "did not find pattern j in target 2 ^ Nat.log 2 ⌊‖↑ρ‖⌋₊ ≤ ⌊‖↑ρ‖⌋₊" — right, there's no j in the target; I need rw [hρj] (forward: Nat.log... → j). ✓ Fix direction. Let me apply the fixes.
Fixes: `lt_of_not_le` → `lt_of_not_ge`, `Nat.le_floor_iff` argument, stray `ring`, and an `rw` direction.

More errors: 1. Line 1774: one more `lt_of_not_le` (in hsub's hpowle — the pattern `lt_of_not_le hρF.2.1` — my replace only caught `lt_of_not_le hρ3`). Fix: `lt_of_not_ge hρF.2.1`. 2. Line 1811 (hmax): `nlinarith [h3, h4]` failed on `max (2^j−1) (2^(j+1)) = 2^(j+1)` — nlinarith can't do max. Use `max_eq_right`: max_eq_right (h : a ≤ b) : max a b = b. Need 2^j−1 ≤ 2^{j+1}: linarith [h3, h4]: 2^{j+1} = 2·2^j ≥ 2·2 = 4 > 2^j−1 ✓. So `exact max_eq_right (by linarith [h3, h4])`. But careful — the goal's max is `max (2^j−1) (2^(j+1))` — after rw [h1, h2] — h1 : |2^{j+1}| = 2^{j+1}, h2 : |2^j−1| = 2^j−1: goal becomes max (2^j−1) (2^{j+1}) = 2^{j+1}: max_eq_right ✓. 3. `Finset.eq_empty_iff_forall_not_mem` doesn't exist — use `Finset.eq_empty_iff_forall_notMem` (camelCase, like indicator_of_notMem) or `Finset.eq_empty_iff_forall_not_mem`... The banked gotcha says camelCase notMem in this Mathlib. Use `Finset.eq_empty_iff_forall_notMem`. Let me check: there's `Finset.eq_empty_iff_forall_notMem : s = ∅ ↔ ∀ x, x ∉ s`. Yes. 4. Line 1817: "No goals" — after the failed eq_empty the subsequent tactics error. Will re-check after fixing 3. 5. Line 1829: `mul_nonneg (by norm_num) A0count_pos.le (by positivity)` — mul_nonneg takes TWO args: mul_nonneg (ha : 0 ≤ a) (hb : 0 ≤ b). I passed three: `mul_nonneg (mul_nonneg (by norm_num) A0count_pos.le (by positivity)) h1` — wait the original: `exact mul_nonneg (mul_nonneg (by norm_num) A0count_pos.le (by positivity)) h1` — the INNER mul_nonneg got 3 args: (by norm_num) A0count_pos.le (by positivity) — the target 0 ≤ 3 * A0count * (2^j+3): = 3 * (A0count * (2^j+3)) or (3*A0count)*(2^j+3)? mul_nonneg a b : 0 ≤ a*b. For 3*A0count*(2^j+3) parsed as (3*A0count)*(2^j+3): mul_nonneg (h : 0 ≤ 3*A0count) (by positivity : 0 ≤ 2^j+3): inner = mul_nonneg (by norm_num : (0:ℝ) ≤ 3) A0count_pos.le. So: `mul_nonneg (mul_nonneg (by norm_num : (0:ℝ) ≤ 3) A0count_pos.le) (by positivity)`. My code had `mul_nonneg (mul_nonneg (by norm_num) A0count_pos.le (by positivity)) h1` — the inner has 3 args (error "Function expected at mul_nonneg ?m A0count_pos.le" — because mul_nonneg (by norm_num) A0count_pos.le is already complete, then (by positivity) is an extra arg). Fix to the 2-arg nesting. Wait — also the outer target: 0 ≤ 3 * A0count * (2^j + 3) * Real.log(...): the sum-empty goal is `0 ≤ 3 * A0count * (2 ^ j + 3) * Real.log (3 * 2 ^ (j + 1) + 5)`: = ((3*A0count)*(2^j+3))*log: mul_nonneg (mul_nonneg (mul_nonneg (by norm_num) A0count_pos.le) (by positivity)) h1 — that's what I had: mul_nonneg (mul_nonneg (by norm_num) A0count_pos.le (by positivity)) h1 — the INNER is `mul_nonneg (by norm_num) A0count_pos.le (by positivity)` — 3 args again! The middle layer: 0 ≤ 3*A0count*(2^j+3) = (3*A0count)*(2^j+3): mul_nonneg (0 ≤ 3*A0count) (0 ≤ 2^j+3): = mul_nonneg (mul_nonneg (by norm_num) A0count_pos.le) (by positivity). So full: mul_nonneg (mul_nonneg (mul_nonneg (by norm_num) A0count_pos.le) (by positivity)) h1. My original text: `exact mul_nonneg (mul_nonneg (by norm_num) A0count_pos.le (by positivity)) h1` — inner mul_nonneg with 3 args (by norm_num), A0count_pos.le, (by positivity) — ERROR. Fix: add the paren layer. Let me apply these fixes.
More fixes: another `lt_of_not_le`, `max_eq_right` for the max, `Finset.eq_empty_iff_forall_notMem` (camelCase), and the `mul_nonneg` arity.

Two linarith failures (both nlinarith spots I wrote as nlinarith? no — they're linarith calls failing on nonlinear goals): 1.

Two nonlinear spots need explicit `mul_le_mul` chains instead of linarith.

shell_inlo compiles clean. Now shell_inhi and shell_up — same template with the d-function changed. Let me write both, carefully adjusting: **shell_inhi** (R/2 < ‖ρ‖ ≤ R−2): d ρ := R − ‖(ρ:ℂ)‖. - hdj: 1 ≤ Nat.log 2 ⌊R−‖ρ‖⌋₊: ⌊d⌋₊ ≥ 2 (d ≥ 2 since ‖ρ‖ ≤ R−2) ⟹ Nat.log 2 ≥ 1 (Nat.log 2 2 = 1 ✓ mono). ≤ J: ⌊d⌋₊ ≤ ⌊R⌋₊ (d < R) ✓. - term: g ≤ 2m/d ≤ 2m/2^{jf}: g ρ = m·R/(‖ρ‖‖s−ρ‖): ‖s−ρ‖ ≥ R−‖ρ‖ = d (reverse triangle: ‖s‖−‖ρ‖ = R−‖ρ‖ ≥ 2 > 0 ✓ abs_of_nonneg); ‖ρ‖ ≥ R/2: m·R/(‖ρ‖‖s−ρ‖) ≤ m·R/((R/2)·d) = 2m/d ✓; 2m/d ≤ 2m/2^{jf} (2^{jf} ≤ d ✓). - count per j ∈ Ico: fiber zeros: d ∈ [2^j, 2^{j+1}): a := R−2^{j+1}−1, b := R−2^j, c := R/2−1: - |γ| ≥ ‖ρ‖−1: ‖ρ‖ = R−d > R−2^{j+1} (d < 2^{j+1}) ⟹ ‖ρ‖−1 > a ⟹ |γ| ≥ a... need a ≤ |γ|: |γ| ≥ ‖ρ‖−1 ≥ ... ‖ρ‖−1 > a ⟹ |γ| > a ⟹ ≥ ✓ linarith. - |γ| ≤ ‖ρ‖ ≤ b: d ≥ 2^j ⟹ ‖ρ‖ ≤ R−2^j = b ✓. - c ≤ |γ|: ‖ρ‖ > R/2 ⟹ ‖ρ‖−1 > R/2−1 = c ✓. - hM1: 1 ≤ max a c: c = R/2−1 ≥ 1 (R ≥ 4): le_max_right.trans ✓. - hMb: max a c ≤ b: max_le_iff: a ≤ b ⟺ R−2^{j+1}−1 ≤ R−2^j ⟺ 2^j ≤ 2^{j+1}+1 ✓; c ≤ b ⟺ R/2−1 ≤ R−2^j ⟺ 2^j ≤ R/2+1: 2^j ≤ d·... 2^j ≤ d (in the fiber) hmm — but hMb is per-j, not per-element: 2^j ≤ R/2+1 needs j-bounds only: j ≤ J ⟹ 2^j ≤ 2^J ≤ R ⟹ 2^j ≤ R ≤ R/2+1·... R ≤ R/2+1 ⟺ R/2 ≤ 1 — FALSE. Hmm! c ≤ b: R/2−1 ≤ R−2^j ⟺ 2^j ≤ R/2+1: with 2^j ≤ R (from j ≤ J): 2^j ≤ R = R/2+R/2: need 2^j−R/2 ≤ 1: NOT guaranteed (2^j could be near R). Wait — in the fiber, d ≥ 2^j and d < R/2 (since ‖ρ‖ > R/2): so 2^j ≤ d < R/2: 2^j < R/2 — but that's PER-ELEMENT (in the fiber); for the count brick the fiber is FS.filter(jf = j) — nonempty fibers have 2^j < R/2. But hMb must hold even for the brick application on possibly-empty fibers? If the fiber is empty, the brick's conclusion LHS = 0 — but the brick's hypotheses hM1/hMb must still be discharged! For j with 2^j ≥ R/2: fiber empty (all elements have d ≥ 2^j... wait elements of the fiber have d ∈ [2^j, 2^{j+1}): if 2^j ≥ R/2 then d ≥ R/2 contradicting d < R/2 — so fiber empty). But the brick application needs hMb REGARDLESS. Hmm — handle: in hcount, case-split: if 2^j ≥ R/2 (or c > b), show the fiber is empty directly (element: d ≥ 2^j ≥ R/2 but d < R/2 — contradiction) ⟹ sum = 0 ≤ cnt j. Else apply the brick with c ≤ b. Actually cleaner: keep the by_cases hj : j ∈ Ico 1 (J+1) structure, and INSIDE the Ico case, by_cases h2jR : (2:ℝ)^j ≤ R/2 hmm — wait for j ∈ Ico 1 (J+1): is 2^j < R/2 automatic? j ≤ J: 2^j ≤ 2^J ≤ R: could be 2^j ∈ (R/2, R]: possible! So yes need the sub-case. Structure: ``` by_cases hj : j ∈ Ico 1 (J+1) · by_cases hbig : R / 2 ≤ (2:ℝ)^j · -- fiber empty: elements have d ≥ 2^j ≥ R/2 but d < R/2 have hempty : FS.filter (...) = ∅ := ... rw [hempty, Finset.sum_empty]; positivity-ish · -- the brick with c ≤ b push Not at hbig apply sum_zeroMult_le_of_im_band ... (c ≤ b from 2^j < R/2 ⟹ R/2−1 < R−2^j hmm c ≤ b ⟺ 2^j ≤ R/2+1 ✓ from 2^j < R/2) · empty via hdj ``` Hmm wait — but actually the emptiness argument via d ≥ 2^j needs 2^{jf} ≤ d (the pow-lower bound), which needs ⌊d⌋₊ ≠ 0 ✓ (d ≥ 2 in FS). Fine. Hmm — hold on, actually simpler: choose c := 1?? The sign-separation just needs c ≥ 0-ish with max a c ≥ 1 and c ≤ b and c ≤ |γ|. Take c := 1: |γ| ≥ 1?? Not true in general... |γ| ≥ ‖ρ‖−1 ≥ R/2−1 ≫ 1 ✓ provable. c := 1: max a c: if a ≥ 1: M = a (fine, M ≥ 1 ✓); if a < 1: M = 1: M ≤ b ⟺ 1 ≤ b = R−2^j ✓ (2^j ≤ R−1 hmm 2^j ≤ R/2 in the non-empty case ⟹ b = R−2^j ≥ R/2 ≥ 1 ✓). So c := 1 works and c ≤ b only needs b ≥ 1 which holds in the non-empty case (2^j < R/2 ⟹ b > R/2 ≥ 1 ✓). Same case-split needed anyway. Keep c := R/2−1 — no, with c := R/2−1, M = max a (R/2−1): M ≤ b requires both a ≤ b ✓ and R/2−1 ≤ b ⟺ 2^j ≤ R/2+1 ✓ in the non-empty case (2^j < R/2 ⟹ 2^j ≤ R/2+1·... hmm 2^j < R/2 gives R−2^j > R/2 > R/2−1 ✓ c < b ✓). OK either works. Keep c := R/2−1. - brick: cnt j := 3·A₀·(b−a+2)·log(3·max|a||b|+5): b−a+2 = (R−2^j)−(R−2^{j+1}−1)+2 = 2^j+3 ✓ (2^{j+1} = 2·2^j). max|a||b|: bound ≤ R+1 for the log: log(3·max|a||b|+5) ≤ 2L via log_three_le_two_log with x := max|a||b| ≤ 3R: |a| = |R−2^{j+1}−1| ≤ max(R, 2^{j+1}+1): 2^{j+1} ≤ 2R ⟹ 2^{j+1}+1 ≤ 2R+1 ≤ 3R hmm need |a| ≤ 3R and |b| ≤ 3R: |b| = R−2^j ≤ R ✓; |a| ≤ R+2^{j+1}+1 ≤ R+2R+1 = 3R+1: hmm |a| ≤ max(a, −a) with a = R−2^{j+1}−1 ≤ R ✓ and −a = 2^{j+1}+1−R ≤ 2^{j+1}+1 ≤ 2R+1: so |a| ≤ max(R, 2R+1) = 2R+1 ≤ 3R ✓ (R ≥ 1). max|a||b| ≤ 3R ✓ (max_le (2R+1 ≤ 3R) (R ≤ 3R)). x0 : 0 ≤ max|a||b| ✓. cnt j ≤ 3A₀(2^j+3)·2L (trans with mul_le_mul_of_nonneg_left (log_three_le_two_log...) (nonneg of 3A₀(2^j+3))). Hmm wait — hcount's stated bound must be a single expression cnt j for dyadic_family_le. For inlo I stated hcount with the brick-form bound and then hper did the ≤ 30A₀L step. Same here: hcount : ≤ 3*A0count*((2:ℝ)^j+3)*Real.log(3*max|R−2^{j+1}−1||R−2^j|+5)... then hper: (2/2^j)·that ≤ 30A₀L. The max expression is ugly; alternative: state hcount's RHS directly with the 2L form: ≤ 3*A0count*((2:ℝ)^j+3)*(2*Real.log R) — discharging via brick + log bound inside hcount. Cleaner for hper. Let me do that: hcount's RHS := 3*A0count*((2:ℝ)^j+3)*(2*Real.log R); inside, apply brick then trans via the log bound. For j ∉ Ico ∪ {2^j ≥ R/2}: empty ⟹ 0 ≤ RHS ✓ (nonneg). Then hper: (2/2^j)·3A₀(2^j+3)·2L = 12A₀L(1+3/2^j) ≤ 12A₀L·(5/2) = 30A₀L ✓ same algebra as inlo. Σ ≤ J·30A₀L ≤ 2L·30A₀L = 60A₀L². **shell_up** (R+2 ≤ ‖ρ‖): d ρ := ‖(ρ:ℂ)‖ − R. - FS := F.filter (fun ρ => ¬ ‖(ρ:ℂ)‖ < R+2) — the fifth piece of the iterated split is F.filter ¬P4 with P4 := ‖ρ‖ < R+2. Elements: R+2 ≤ ‖ρ‖ ∧ ‖ρ‖ < 2R+1 (F membership). - hdj: u := ‖ρ‖−R ∈ [2, R+1): ⌊u⌋₊ ≥ 2 ⟹ log ≥ 1; ⌊u⌋₊ ≤ ⌊R⌋₊? u < R+1: ⌊u⌋₊ ≤ ⌊R⌋₊ hmm u < R+1 ⟹ ⌊u⌋₊ ≤ ⌊R⌋₊?? u < R+1 ⟹ ⌊u⌋₊ ≤ ⌊R+1⌋₊−1 hmm: u < R+1 ⟹ ⌊u⌋₊ ≤ R... e.g. R = 100.3, u = 100.9: ⌊u⌋₊ = 100 = ⌊R⌋₊ ✓; u = 100.999 < 101.3 = R+1 ✓ ⌊u⌋₊ = 100 ✓. In general u < R+1 ⟹ ⌊u⌋₊ ≤ ⌊R⌋₊: since ⌊u⌋₊ ≤ u < R+1 ⟹ ⌊u⌋₊ < R+1 ⟹ ⌊u⌋₊ ≤ ⌈R⌉... for naturals: ⌊u⌋₊ < R+1 (real) ⟹ ⌊u⌋₊ ≤ ⌊R+1⌋₊−1 = ⌊R⌋₊ hmm: ⌊u⌋₊ ≤ u < R+1: ⌊u⌋₊ < R+1: ⌊u⌋₊+... Let me just: u < R+1 ⟹ ⌊u⌋₊ ≤ ⌊R⌋₊?? Counter: R = 100.9, u = 100.95: ⌊u⌋₊ = 100 = ⌊R⌋₊ ✓. R = 100.2, u = 100.99 < 101.2: ⌊u⌋₊ = 100 = ⌊R⌋₊ ✓. Try R = 100.999, u = 100.9995: ⌊u⌋₊ = 100, ⌊R⌋₊ = 100 ✓. Seems true: u < R+1: ⌊u⌋₊ < R+1: suppose ⌊u⌋₊ ≥ ⌊R⌋₊+1: then u ≥ ⌊u⌋₊ ≥ ⌊R⌋₊+1 > R (⌊R⌋₊+1 > R ✓ Nat.lt_floor_add_one) ⟹ u > R ⟹ ... need u ≥ R+1 for contradiction: ⌊u⌋₊ ≥ ⌊R⌋₊+1 ⟹ u ≥ ⌊R⌋₊+1 (Nat.floor_le... (⌊u⌋₊:ℝ) ≤ u) hmm u ≥ (⌊u⌋₊:ℝ) ≥ (⌊R⌋₊+1:ℝ) = ⌊R⌋₊+1 > R: gives u > R — not u ≥ R+1. Hmm: ⌊u⌋₊ ≥ ⌊R⌋₊+1 as NATURALS: u ≥ ⌊u⌋₊ ≥ ⌊R⌋₊+1: u ≥ ⌊R⌋₊+1: is ⌊R⌋₊+1 ≥ R+1? NO: ⌊R⌋₊+1 < R+1+1... ⌊R⌋₊+1 ∈ (R, R+1]. So u ≥ ⌊R⌋₊+1 doesn't contradict u < R+1?? u ≥ ⌊R⌋₊+1 and u < R+1: ⌊R⌋₊+1 ≤ R+1 ✓ consistent possible: e.g. R = 100.3, ⌊R⌋₊+1 = 101: u ∈ [101, 101.3): u = 101.1 < 101.3 ✓ and ⌊u⌋₊ = 101 = ⌊R⌋₊+1 — COUNTEREXAMPLE to ⌊u⌋₊ ≤ ⌊R⌋₊! So ⌊u⌋₊ can be ⌊R⌋₊+1. Then Nat.log 2 ⌊u⌋₊ ≤ Nat.log 2 (⌊R⌋₊+1): is that ≤ J = Nat.log 2 ⌊R⌋₊? NOT always: R = 100.3: ⌊R⌋₊ = 100, ⌊u⌋₊ = 101: log₂100 = 6, log₂101 = 6 ✓; but R near powers of 2: R = 127.5: ⌊R⌋₊ = 127: log₂127 = 6; u ∈ [127.5ish, 128.5): ⌊u⌋₊ could be 128: log₂128 = 7 > 6 = J! PROBLEM. Hmm — but wait: for up, u = ‖ρ‖−R < R+1 — and I want jf ρ = Nat.log 2 ⌊u⌋₊ ≤ J. When u ∈ [R, R+1) hmm: u < R+1; 2^J ≤ R (2^J ≤ ⌊R⌋₊ ≤ R) and 2^{J+1} > ⌊R⌋₊: 2^{J+1} > R... u < R+1 ≤ 2^{J+1}+1: ⌊u⌋₊ ≤ R < 2^{J+1}: hmm ⌊u⌋₊ ≤ ⌊R+1−⌋: u < R+1 ⟹ ⌊u⌋₊ ≤ R (floor_le of u < R+1?? u < R+1 ⟹ ⌊u⌋₊ < R+1 ⟹ ⌊u⌋₊ ≤ R in reals, as naturals ⌊u⌋₊ ≤ ⌊R+1−ε⌋...). Cleaner: ⌊u⌋₊ < R+1 (real ineq: (⌊u⌋₊:ℝ) ≤ u < R+1) ⟹ ⌊u⌋₊ ≤ R (nat: ⌊u⌋₊ < R+1 hmm real-cast: (⌊u⌋₊:ℝ) < R+1 ⟹ ⌊u⌋₊ ≤ R? as ⌊u⌋₊ is a natural: (⌊u⌋₊:ℝ) < R+1 doesn't give nat ≤ ⌊R⌋₊. e.g. ⌊u⌋₊ = 128, R = 127.5: (128:ℝ) < 128.5 ✓ but 128 > 127 = ⌊R⌋₊. Fix: use J' := Nat.log 2 ⌊R+1⌋₊ for the up family? Then 2^{J'} could be > R (⌊R+1⌋₊ = ⌊R⌋₊+1: 2^{J'} ≤ ⌊R⌋₊+1 ≤ R+1): the J' ≤ 2L+1-ish bound: 2^{J'} ≤ R+1 ⟹ J'·log2 ≤ log(R+1) ≤ log(2R) = log2+L ⟹ J' ≤ 1+L/log2 ≤ 1+2L ≤ 3L·... J' ≤ 3L hmm 1+2L ≤ 3L ⟺ 1 ≤ L ✓. Fine — the count of shells for up ≤ J' ≤ 3L: up ≤ 15A₀L·J' ≤ 45A₀L². Or simpler: prove Nat.log 2 ⌊u⌋₊ ≤ J directly: 2^{jf} ≤ ⌊u⌋₊ ≤ u < R+1 and I need jf ≤ J: suppose jf ≥ J+1: 2^{J+1} ≤ 2^{jf} ≤ ⌊u⌋₊ ≤ u < R+1 ⟹ 2^{J+1} < R+1. But 2^{J+1} > ⌊R⌋₊ ≥ R−1 hmm 2^{J+1} ≥ ⌊R⌋₊+1 > R ⟹ 2^{J+1} > R ⟹ 2^{J+1} ≥ ... 2^{J+1} is an integer > R: 2^{J+1} ≥ ⌊R⌋₊+1: and u < R+1: 2^{J+1} ≤ u < R+1 ⟹ 2^{J+1} < R+1: but 2^{J+1} > R with 2^{J+1} nat: 2^{J+1} ≥ ⌊R⌋₊+1 hmm circular. Let me think: 2^{J+1} > R (strict, since 2^{J+1} > ⌊R⌋₊ ≥ ... Nat.lt_pow_succ_log_self: ⌊R⌋₊ < 2^{J+1}: (⌊R⌋₊:ℝ) < 2^{J+1}: and R < ⌊R⌋₊+1 ≤ 2^{J+1}: so R < 2^{J+1}. And jf ≤ J ⟸ 2^{jf} ≤ 2^J?? no: jf ≤ J ⟸ ⌊u⌋₊ ≤ ⌊R⌋₊ hmm. Alternative: jf ≤ J ⟸ 2^{jf+1} ≤ 2^{J+1}... no. Direct: 2^{jf} ≤ ⌊u⌋₊ (pow_log_le_self) and ⌊u⌋₊ < 2^{J+1} (since ⌊u⌋₊ ≤ u < R+1 ≤ ... hmm R+1 ≤ 2^{J+1}? 2^{J+1} > R and 2^{J+1} nat ⟹ 2^{J+1} ≥ ⌈R⌉ hmm 2^{J+1} > R ⟹ 2^{J+1} ≥ R+... for real R: 2^{J+1} > R ⟹ R+1 ≤ 2^{J+1}? NO: R = 127.5, 2^{J+1} = 128 > 127.5: R+1 = 128.5 > 128! So u < R+1 = 128.5 could have ⌊u⌋₊ = 128 with jf = 7 > J = 6. CONFIRMED PROBLEM. Resolution: for the up family, J_up := Nat.log 2 ⌊R+1⌋₊ hmm or just take J_up := J+1: claim jf ρ ≤ J+1: 2^{jf} ≤ ⌊u⌋₊ ≤ u < R+1 < 2^{J+1}+1 ⟹ 2^{jf} < 2^{J+1}+1 ⟹ 2^{jf} ≤ 2^{J+1} (nats) ⟹ jf ≤ J+1 ✓. And count shells: card Ico 1 (J+2) = J+1 ≤ 2L+1 ≤ 3L (L ≥ 9... 2L+1 ≤ 3L ⟺ 1 ≤ L ✓). So for up: J' := J+1, shell count J+1 ≤ 3L, per-shell ≤ 15A₀L: up ≤ 45A₀L². Hmm wait — per-shell for up was 15A₀L (C₁ = 1: (1/2^j)·3A₀(2^j+3)·2L = 6A₀L(1+3/2^j) ≤ 6A₀L·(5/2) = 15A₀L). up ≤ (J+1)·15A₀L ≤ 3L·15A₀L = 45A₀L². Adjust the totals: 2·lowZeroConst + 60+60+45+91-absorb + 2688Ĉ = fine (final 2900 unchanged: 60+60+45 = 165 ≤ 180; 165/2+2688+46 = 82.5+2688+46 = 2816.5 ≤ 2900 ✓). - term: g ≤ m/u ≤ m/2^{jf}: g = m·R/(‖ρ‖‖s−ρ‖): ‖s−ρ‖ ≥ ‖ρ‖−R = u (reverse triangle: ‖ρ‖−‖s‖ = ‖ρ‖−R ≥ 2 > 0: ‖s−ρ‖ ≥ |‖s‖−‖ρ‖| = ‖ρ‖−R ✓ abs_norm_sub_norm_le: |‖s‖−‖ρ‖| ≤ ‖s−ρ‖: |R−‖ρ‖| = ‖ρ‖−R ✓); ‖ρ‖ ≥ R: m·R/(‖ρ‖u) ≤ m·R/(R·u) = m/u ✓; m/u ≤ m/2^{jf} (2^{jf} ≤ u) ✓. - count per j ∈ Ico 1 (J'+1): fiber: u ∈ [2^j, 2^{j+1}): a := R+2^j−1, b := R+2^{j+1}, c := R+1: - |γ| ≥ ‖ρ‖−1 ≥ R+2^j−1 = a (u ≥ 2^j ⟹ ‖ρ‖ ≥ R+2^j) ✓. - |γ| ≤ ‖ρ‖ ≤ b: u < 2^{j+1} ⟹ ‖ρ‖ < R+2^{j+1} ⟹ ≤ b ✓. - c ≤ |γ|: ‖ρ‖−1 ≥ R+1 ⟺ u ≥ 2 ✓. - hM1: max a c = a (a ≥ c ⟺ 2^j ≥ 2 ⟺ j ≥ 1 ✓) ≥ R ≥ 1 ✓... max a c ≥ c = R+1 ≥ 1 ✓ (le_max_right). - hMb: max a c ≤ b: a ≤ b ⟺ 2^j−1 ≤ 2^{j+1} ✓; c ≤ b ⟺ R+1 ≤ R+2^{j+1} ⟺ 1 ≤ 2^{j+1} ✓. - brick cnt: b−a+2 = 2^j+3 ✓; max|a||b| = b = R+2^{j+1} (a ≥ 0 ✓ |a| = a ≤ b ✓): log(3b+5) ≤ 2L: b ≤ 3R: 2^{j+1} ≤ 2R: j ≤ J' = J+1: 2^j ≤ 2^{J+1} = 2·2^J ≤ 2R ⟹ 2^{j+1} = 2·2^j ≤ 4R?!?!

Ugh — wait actually: do I need 2^{j+1} ≤ 2R for the brick per j ∈ Ico 1 (J'+1)? j ranges to J' = J+1: at j = J+1: 2^j = 2^{J+1} ≤ 2R: 2^{j+1} = 2^{J+2} ≤ 4R. So b ≤ 5R, log(3·5R+5) = log(15R+5) ≤ log(16R) (5 ≤ R) = log16+L ≤ 2L ✓ (4 ≤ L).

CLEANEST: 3b+5 ≤ 8b (5 ≤ 5b ✓) ⟹ log ≤ log 8 + log b: log 8 ≤ 3 (8 ≤ e^3 ⟸ e^3 ≥ 2.7^3 = 19.683 ✓) and log b ≤ log(5R) = log 5 + L ≤ L/9·... log 5 ≤ L ⟸ 5 ≤ R ✓: so log(3b+5) ≤ 3 + (L + L·)... = 3 + log5 + L ≤ 3 + L + L = 3+2L ≤ 2L+L/3·... NO — 3+2L vs 2L: exceeds. log(3b+5) ≤ 2L fails this way. Go with the 16R route: log(3b+5) ≤ log(16R) = 4log2 + L: 4log2 ≤ 4·0.7 = 2.8?? log2 ≤ 1 (have) ⟹ 4log2 ≤ 4: total ≤ 4+L ≤ L+L = 2L ⟺ 4 ≤ L ✓ (L ≥ 9, linarith). ✓ no new exp facts: 4·log2 ≤ 4 (log_two_le_one) and 4 ≤ L (from L ≥ 9). And 3b+5 ≤ 16R ⟸ b ≤ 5R (15R+5 ≤ 16R ⟺ 5 ≤ R ✓). So for up: log bound: log(3b+5) ≤ 2L with b = R+2^{j+1} ≤ 5R for j ≤ J+1. And cnt j ≤ 3A₀(2^j+3)·2L. per-shell (1/2^j)·that ≤ 6A₀L(1+3/2^j) ≤ 15A₀L. Σ over Ico 1 (J+2): card J+1 ≤ 2L+1 ≤ 3L: up ≤ 45A₀L². Hmm wait — hcount is per j : ℕ (all j). For j ∈ Ico 1 (J'+1) with J' := J+1: apply brick. Outside: empty via hdj (jf ∈ Ico 1 (J'+1) for elements). The j ∈ Ico case also needs 2^{j+1} ≤ 4R for the log: j ≤ J' = J+1 ✓ as computed. - The d-function's hdj for up: 1 ≤ Nat.log 2 ⌊‖ρ‖−R⌋₊ (⌊u⌋₊ ≥ 2 ⟸ u ≥ 2 ⟸ ‖ρ‖ ≥ R+2) and ≤ J' = J+1: shown above (2^{jf} ≤ ⌊u⌋₊ ≤ u < R+1 hmm — direct nat route: 2^{jf} ≤ ⌊u⌋₊ (nat) and ⌊u⌋₊ ≤ u < R+1 ≤ 2^{J+1}+... let me redo cleanly: claim jf ≤ J+1 ⟸ 2^{jf} ≤ 2^{J+1} (pow injective... Nat.pow_le_pow_iff_right (2 > 1)... or Nat.log_mono: jf = Nat.log 2 ⌊u⌋₊ ≤ Nat.log 2 ⌊R+1−ε⌋...). Route: ⌊u⌋₊ ≤ u < R+1 ⟹ (⌊u⌋₊:ℝ) < R+1: and 2^{J+1} ≥ ⌊R⌋₊+1 > R hmm: 2^{J+1} > ⌊R⌋₊ (nat, lt_pow_succ) ⟹ 2^{J+1} ≥ ⌊R⌋₊+1 (nat) ⟹ (2^{J+1}:ℝ) ≥ ⌊R⌋₊+1 > R (Nat.lt_floor_add_one). So R < 2^{J+1}: (⌊u⌋₊:ℝ) < R+1 ≤ 2^{J+1}... R+1 ≤ 2^{J+1}?? R < 2^{J+1} and 2^{J+1} ∈ ℕ: R+1 ≤ 2^{J+1} ⟺ ⌈R⌉ ≤ 2^{J+1}: R < 2^{J+1} with 2^{J+1} nat ⟹ ⌈R⌉ ≤ 2^{J+1} ✓ (ceil ≤ since 2^{J+1} is a nat > R... hmm: (2^{J+1}:ℝ) > R ⟹ ⌈R⌉₊ ≤ 2^{J+1}: Nat.ceil_le... yes: ⌈R⌉₊ ≤ 2^{J+1} ⟸ R ≤ (2^{J+1}:ℝ) (Nat.le_ceil... reverse: ceil_le: ⌈R⌉₊ ≤ n ⟺ R ≤ n: R < 2^{J+1} ⟹ R ≤ 2^{J+1} ⟹ ⌈R⌉₊ ≤ 2^{J+1} — hmm that's ⌈R⌉₊ not R+1. (⌊u⌋₊:ℝ) < R+1: ⌊u⌋₊ ≤ ⌈R⌉₊: (⌊u⌋₊:ℝ) < R+1 ⟹ ⌊u⌋₊ ≤ ⌈R⌉₊ (nat: ⌊u⌋₊ < R+1 as reals ⟹ ⌊u⌋₊+1 ≤ ... e.g. R = 100.2: R+1 = 101.2: ⌊u⌋₊ < 101.2 ⟹ ⌊u⌋₊ ≤ 101 = ⌈R⌉₊ ✓ general: ⌊u⌋₊ ≤ ⌈R⌉₊ ⟸ (⌊u⌋₊:ℝ) < R+1 — since ⌊u⌋₊ nat and ⌊u⌋₊ < R+1 ⟹ ⌊u⌋₊ ≤ ⌈R⌉₊?? ⌈R⌉₊ = smallest nat ≥ R: any nat n < R+1 has n ≤ ⌈R⌉₊?? n = 101, R = 100.2: ⌈R⌉ = 101 ✓; R = 100.9: ⌈R⌉ = 101: n < 101.9 ⟹ n ≤ 101 ✓; R = 101.0 exactly: ⌈R⌉ = 101: n < 102 ⟹ n ≤ 101 ✓. Yes: n < R+1 ⟹ n ≤ ⌈R⌉₊ (n+... n ≤ R+... since n < R+1 ⟹ n ≤ R (n nat, R... no: n < R+1 ⟹ n ≤ ⌈R⌉₊: proof: n−1 < R ⟹ n−1 ≤ ⌊R⌋₊... I'll take the route: ⌊u⌋₊ ≤ u and 2^{jf} ≤ ⌊u⌋₊ (nats) ⟹ (2^{jf}:ℝ) ≤ u < R+1: and (2^{J+1}:ℝ) > R: both powers of 2 (nat): 2^{jf} < R+1 ≤ ... hmm I want 2^{jf} ≤ 2^{J+1}: 2^{jf} < R+1 and 2^{J+1} > R: 2^{jf}, 2^{J+1} ∈ ℤ (nats): if 2^{jf} > 2^{J+1} then 2^{jf} ≥ 2^{J+2} > 2R ≥ R+1 hmm 2^{J+2} = 2·2^{J+1} > 2R ≥ R+1 (R ≥ 1) — contradicts 2^{jf} < R+1 ✓. So 2^{jf} ≤ 2^{J+1} ⟹ jf ≤ J+1 ✓ (Nat.pow_le_pow_iff_right... `Nat.pow_le_pow_iff_right (hb : 1 < b) : b^m ≤ b^n ↔ m ≤ n` ✓). OK. Also for inhi's hdj: jf = Nat.log 2 ⌊R−‖ρ‖⌋₊ ≤ J: ⌊d⌋₊ ≤ ⌊R⌋₊ (d < R ✓ since d = R−‖ρ‖ < R) ⟹ mono ✓. Fine (no +1 issue since d < R strictly). Let me now write shell_inhi and shell_up. Also the cnt RHS: for inhi I decided cnt j := 3*A0count*((2:ℝ)^j+3)*(2*Real.log R) directly. For inlo I kept the brick-form; for consistency and simplicity in hper, maybe use the 2L-form for inhi/up. inlo already works — leave it. Actually for the assembly totals: inlo ≤ 60A₀L², inhi ≤ 60A₀L², up ≤ 45A₀L². Let me write shell_inhi now (cloning shell_inlo's structure with d := R−‖ρ‖ and the sub-case split for 2^j ≥ R/2).
shell_inlo compiles. Now shell_inhi — same template, d := R−‖ρ‖, with the extra sub-case for fibers where 2^j ≥ R/2 (empty).

The heredoc with single quotes inside the python string — the issue: the python code contains `'''` triple-quotes and the content has no problem, but the bash heredoc `<< 'EOF'` should be literal... The error "unexpected EOF looking for matching ''" at line 161 — the content contains an apostrophe that closed something? With `<< 'EOF'` (quoted delimiter) the content is literal, no expansion — apostrophes are fine. Hmm, line 161... the content includes `(by omega : 1 ≤ j)` etc. Wait — the outer Bash command itself is wrapped in double quotes?? No, I passed it as the command string. The issue may be the python `'''` inside interacting with... Actually the error is from bash parsing — the heredoc terminator must be exactly `EOF` at line start. My content contains lines starting with `EOF`? No. Hmm — actually the problem: my command had `<< 'EOF'` and the content includes the two SINGLE-QUOTE characters in `<< 'EOF'`... that's standard. Let me look — "unexpected EOF while looking for matching `''" — there's an unbalanced single quote in the COMMAND portion. The python string uses `'''` delimiters and the Lean content includes `‖`, fine — but the content also includes `'` characters? Lean code: `Nat.lt_pow_succ_log_self`... `pow_succ'` — THERE: `pow_succ'` contains a single quote! Inside the python triple-quoted string that's fine, but bash heredoc with quoted delimiter is literal so `'` is fine there too... Wait — the REAL issue: the heredoc is inside `python - << 'EOF'` — that's fine. But my Bash tool call wraps everything... The tool said "Shell command failed /usr/bin/bash: -c: line 161: unexpected EOF". Line 161 of the script. The script content with `pow_succ'` — bash heredoc with quoted delimiter should NOT care. UNLESS the heredoc delimiter got consumed early: my content has a line `open(p, 'w', encoding='utf-8').write(src)` etc. Hmm. Let me just avoid the heredoc-in-bash for large content: use the Write tool to create a temp python file, or better — append the new section via the Edit tool directly (safer). The Edit tool with old_string `end NguyenRH1\n\nend` and new_string = the section + ends. The section is large but Edit handles it. Let me do that.
The bash heredoc choked on the content. Using the Edit tool directly instead.

Error at 1973 — h2's proof: `rw [div_le_div_iff₀ ...]` failed because div_le_div_iff₀ produces an iff, and rw with an iff rewrites the GOAL — the error shows the pattern mismatch: `div_le_div_iff₀` has a different form in this Mathlib. The goal: `R / (‖ρ‖ * (R−‖ρ‖)) ≤ 2 / (R − ‖ρ‖)`. div_le_div_iff₀ (hb : 0 < b) (hd : 0 < d) : a/b ≤ c/d ↔ a*d ≤ c*b. rw [div_le_div_iff₀ h1 h2] should turn the goal into R·(R−‖ρ‖) ≤ 2·(‖ρ‖·(R−‖ρ‖)). The error says the pattern with (‖ρ‖ * (‖ρ‖ * ...)) didn't match — the div_le_div_iff₀ I applied had the denominators unified wrongly: my first arg was `mul_pos hρpos ...` : 0 < ‖ρ‖*(R−‖ρ‖) ✓ b := ‖ρ‖*(R−‖ρ‖); second : 0 < R−‖ρ‖ ✓ d := R−‖ρ‖. Then the iff: a/b ≤ c/d ↔ a·d ≤ c·b with a := R, c := 2: R·(R−‖ρ‖) ≤ 2·(‖ρ‖·(R−‖ρ‖)). Hmm the error pattern shows `?m.1048 / (‖↑ρ‖ * (‖↑ρ‖ * (R - ‖↑ρ‖)))` — the b unified as ‖ρ‖·(‖ρ‖·(R−‖ρ‖))?? That means div_le_div_iff₀'s FIRST hypothesis is 0 < b where the goal's FIRST denominator is... The goal LHS: `R / (‖↑ρ‖ * (R - ‖↑ρ‖))` — the denominator is ‖ρ‖·(R−‖ρ‖). But the pattern shows ‖ρ‖ * (‖ρ‖ * (R−‖ρ‖)) — as if a/b parsed with b = ‖ρ‖·(‖ρ‖·(R−‖ρ‖))... OH — I bet this Mathlib's div_le_div_iff₀ has signature `div_le_div_iff₀ (hb : 0 < b) (hd : 0 < d) : a / b ≤ c / d ↔ a * d ≤ c * b`? The rw failed to match the goal — maybe the name is different: div_le_div_iff_of_pos? or div_le_div_iff (no ₀)? The error shows the REWRITE tried to match `?a / ?b ≤ ?c / ?d` with ?b := ‖ρ‖·(‖ρ‖·(R−‖ρ‖)) — that's odd. Actually maybe div_le_div_iff₀ in this Mathlib is: `a / b ≤ c / d ↔ a * d ≤ c * b` requires matching the EXACT term `R / (‖ρ‖ * (R − ‖ρ‖))` — should match... Wait, look at the pattern more carefully: `?m.1048 / (‖↑ρ‖ * (‖↑ρ‖ * (R - ‖↑ρ‖))) ≤ ?m.1050 / (R - ‖↑ρ‖)` — the LHS denominator is ‖ρ‖·(‖ρ‖·(R−‖ρ‖)) — that's ‖ρ‖ TIMES the intended denominator. This suggests div_le_div_iff₀'s form is different — perhaps it's `div_le_div_iff₀ : b / a ≤ d / c ↔ ...`? Or the lemma is stated as `(hb : 0 < b) (hd : 0 < d) : a / (b * c) ≤ ...`? Hmm — in recent Mathlib, `div_le_div_iff₀` might be: (hb : 0 < b) (hd : 0 < d) : a / b ≤ c / d ↔ a * d ≤ c * b. Let me just avoid the rw and prove h2 directly: h2 : R / (‖ρ‖·(R−‖ρ‖)) ≤ 2/(R−‖ρ‖): ``` have h2 : R / (‖(ρ : ℂ)‖ * (R - ‖(ρ : ℂ)‖)) ≤ 2 / (R - ‖(ρ : ℂ)‖) := by rw [div_mul_eq_mul_div, div_le_iff₀ (by linarith [hd2] : (0:ℝ) < R - ‖(ρ:ℂ)‖)] ... ``` Alternative cleaner: multiply both sides: R/(‖ρ‖·d) ≤ 2/d ⟺ R·d ≤ 2·(‖ρ‖·d) (mult by d > 0... and divide by d): R/(‖ρ‖·d) = (R/‖ρ‖)/d: then (R/‖ρ‖)/d ≤ 2/d ⟸ R/‖ρ‖ ≤ 2 (div_le_div_of_nonneg_right with d > 0). R/‖ρ‖ ≤ 2 ⟺ R ≤ 2‖ρ‖ ✓ (h5). So: ``` have h2a : R / ‖(ρ : ℂ)‖ ≤ 2 := by rw [div_le_iff₀ hρpos] linarith [h5] -- R ≤ 2‖ρ‖: h5 : R ≤ 2·‖ρ‖ ✓... div_le_iff₀ (hb : 0 < b) : a / b ≤ c ↔ a ≤ c * b: R ≤ 2·‖ρ‖ ✓ h5 have h2 : R / (‖(ρ : ℂ)‖ * (R - ‖(ρ : ℂ)‖)) ≤ 2 / (R - ‖(ρ : ℂ)‖) := by rw [show R / (‖(ρ : ℂ)‖ * (R - ‖(ρ : ℂ)‖)) = (R / ‖(ρ : ℂ)‖) / (R - ‖(ρ : ℂ)‖) from by rw [div_div]] exact div_le_div_of_nonneg_right h2a (by linarith [hd2] : (0 : ℝ) < R - ‖(ρ : ℂ)‖) ``` Hmm — div_le_div_of_nonneg_right : a ≤ b → 0 < c → a/c ≤ b/c? The name in current Mathlib: `div_le_div_of_nonneg_right (hab : a ≤ b) (hc : 0 < c) : a / c ≤ b / c`? I recall `div_le_div_of_nonneg_right` hmm — there's div_le_div_right (ordered field): `div_le_div_right (hc : 0 < c) : a / c ≤ b / c ↔ a ≤ b`. So: `(div_le_div_right (by linarith [hd2] : (0:ℝ) < R - ‖(ρ:ℂ)‖)).mpr h2a` ✓ robust. div_div : a / (b * c)?? div_div : a / b / c = a / (b * c) — so a/(b·c) = a/b/c via (div_div a b c).symm. My show: R/(‖ρ‖·d) = (R/‖ρ‖)/d: `rw [div_div]` on (R/‖ρ‖)/d gives R/(‖ρ‖·d) — so the show's proof is `by rw [div_div]` ✓. Also check div_le_iff₀ exists (used in shell_low h3 — that compiled ✓ `div_le_iff₀ (by linarith [hR] : (0 : ℝ) < R - 3)` gave R ≤ 2·(R−3) ✓ worked). Let me fix h2.
`div_le_div_iff₀`'s form mismatched. Rerouting h2 via `R/‖ρ‖ ≤ 2` + `div_le_div_right`.

Error at 2242 in hdj's h2J1: after `linarith [h2, h4]` — wait the error shows the goal `False` with `a✝ : 2 ^ (J + 1) ≤ R` — that's the by_contra hypothesis from `by_contra hcon` — no wait, the context shows h1✝, hpowle, h1, h2, h3, h4 — the h2J1 block's contents — and `a✝ : 2 ^ (J + 1) ≤ R` — that's from `by_contra`... no. Look: h2J1's goal is `R < (2:ℝ)^(J+1)` — the context has h4 : ⌊R⌋₊ < 2^{J+1}, h2 : R < ⌊R⌋₊+1 — the linarith [h2, h4] should close `R < 2^{J+1}`... but the error's `a✝ : 2 ^ (J + 1) ≤ R` — that's the negation of the goal — so linarith FAILED and the goal state shown is the by_contra'd one? The error is at 2242:8 — `linarith [h2, h4]` in h2J1. But h3 : ↑(2^(J+1)) = 2^(J+1) — the cast direction! h4 : (⌊R⌋₊:ℝ) < (2:ℝ)^(J+1) — wait no: h4 was proved by `rw [← h3]; exact_mod_cast h1` — goal `↑⌊R⌋₊ < 2 ^ (J + 1)` where the RHS is the REAL pow 2^(J+1); rw [← h3] rewrote (2:ℝ)^(J+1) to ↑((2:ℕ)^(J+1)); then exact_mod_cast h1 : ⌊R⌋₊ < 2^(J+1) (ℕ) ✓. So h4 : (⌊R⌋₊:ℝ) < (2:ℝ)^(J+1) ✓. And h2 : R < ⌊R⌋₊+1 ✓. linarith [h2, h4] should give R < 2^{J+1}... Hmm wait — the h4 in context: `h4 : ↑⌊R⌋₊ < 2 ^ (J + 1)` ✓. h2 : `R < ↑⌊R⌋₊ + 1` ✓. Goal `R < 2 ^ (J + 1)` — linarith: R < ⌊R⌋₊+1 and ⌊R⌋₊ < 2^{J+1}: R < 2^{J+1}+1 — NOT R < 2^{J+1}!! ⌊R⌋₊ < 2^{J+1} gives ⌊R⌋₊ ≤ 2^{J+1}−1 (integers!) but linarith works over ℝ and doesn't know ⌊R⌋₊ is an integer! Need the integrality: ⌊R⌋₊ < 2^{J+1} in ℕ ⟹ ⌊R⌋₊ + 1 ≤ 2^{J+1} (ℕ) ⟹ cast: (⌊R⌋₊:ℝ)+1 ≤ 2^{J+1} ⟹ R < ⌊R⌋₊+1 ≤ 2^{J+1} ✓. Fix: ``` have h5 : ⌊R⌋₊ + 1 ≤ 2 ^ (J + 1) := h1 -- h1 : ⌊R⌋₊ < 2^(J+1): Nat.lt_iff_add_one_le ✓ h1 IS ⌊R⌋₊+1 ≤ 2^(J+1) by defeq have h6 : (⌊R⌋₊ : ℝ) + 1 ≤ (2 : ℝ) ^ (J + 1) := by have h7 : ((⌊R⌋₊ + 1 : ℕ) : ℝ) ≤ ((2 ^ (J + 1) : ℕ) : ℝ) := by exact_mod_cast h5 push_cast at h7 rw [h3] at h7 -- h3 : ↑(2^(J+1)) = (2:ℝ)^(J+1) linarith [h7] ``` Hmm h7 : (⌊R⌋₊:ℝ)+1 ≤ ↑(2^(J+1)) — with push_cast: the RHS ↑(2^(J+1)) might stay as a cast or push to (2:ℝ)^(J+1): push_cast at h7 should give (2:ℝ)^(J+1) (push_cast pushes casts inward: ↑(2^(J+1)) = (2:ℝ)^(J+1) via Nat.cast_pow ✓). Then linarith [h2, h7]: R < ⌊R⌋₊+1 ≤ 2^{J+1} ⟹ R < 2^{J+1} ✓. Wait — Nat.lt_iff_add_one_le: a < b ↔ a+1 ≤ b — h1 : ⌊R⌋₊ < 2^(J+1) is DEFINITIONALLY ⌊R⌋₊+1 ≤ 2^(J+1) in Lean 4 (Nat.lt is defined as ·+1 ≤ ·) — so h5 := h1 works directly ✓. Let me fix h2J1: replace the h4/linarith ending with the +1 cast route.
`linarith` can't use ⌊R⌋₊'s integrality — need the +1 cast through ℕ.

Committed (222d65d). Now 3c-iii: the critical shell + final assembly. **shell_crit** (R−2 < ‖ρ‖ < R+2): needs the arc analysis (uniform ‖s−ρ‖ ≥ 1/(32Ĉ)) + the brick count (single window). The hypotheses needed beyond hs/hsz/hR: the gap property hgap and k with R ≥ 4k+5/2 (for the threshold 416Ĉ ≤ R). Signature: ```lean lemma shell_crit {k : ℕ} (hk : 4000 ≤ k) {R : ℝ} (hRlo : 4*(k:ℝ)+5/2 ≤ R) (hgap : ∀ ρ : ℂ, IsNontrivialZero ρ → 1/(16*C0hat(4*(k:ℝ)+9/2)) ≤ |ρ.im − R| ∨ 1 ≤ |ρ.im − R|) {s : ℂ} (hs : ‖s‖ = R) (hsz : ¬ IsNontrivialZero s) : ∑ ρ ∈ (circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ R - 2 ∧ ‖(ρ : ℂ)‖ < R + 2), ‖seriesTerm s ρ‖ ≤ 2688 * C0hat (4*(k:ℝ)+9/2) * A0count * Real.log R ``` Proof structure: - hth := gapCircle_threshold hk : 416·Ĉ ≤ 4k+5/2 ≤ R. - hĈ2 : 2 ≤ Ĉ (two_le_C0hat). - hR : 16002 ≤ R (linarith from hk/hRlo). - **hsep : ∀ ρ ∈ FS, (1/(32*Ĉ)) ≤ ‖s − (ρ:ℂ)‖** — the arc analysis: per ρ ∈ FS: ‖ρ‖ ∈ (R−2, R+2). Set γ := (ρ:ℂ).im, t := s.im. Case split on |s.re| ≤ Real.sqrt 13?? — hmm, √13 requires Real.sqrt: |s.re| ≤ √13 ⟺ s.re² ≤ 13 (sq_le_sq-ish). Use s.re^2 ≤ 13 as the case condition (avoids sqrt): by_cases hre13 : s.re^2 ≤ 13. Case 1 (s.re² ≤ 13): - hRt : R − |t| ≤ 13/R: from 3a's computation: R−|t| = s.re²/(R+|t|) ≤ s.re²/R ≤ 13/R. (Re-derive: hnormSq, ht2 etc. — factor out a helper lemma? The 3a proof has this inline. Let me factor a tiny helper: `norm_circle_re_sq_le {s : ℂ} {R B : ℝ} (hs : ‖s‖ = R) (hR1 : 0 < R) (hre : s.re^2 ≤ B) : R − |s.im| ≤ B / R`. Used twice (3a could use it too but it's proved inline there — leave 3a as is, add the helper now for the crit shell.) Actually — simpler to inline again (~15 lines). But a helper is cleaner. Let me add the helper lemma. - |t−γ| ≥ 1/(32Ĉ): have hgap' := hgap (ρ:ℂ) ρ.2: 1/(16Ĉ) ≤ |γ−R| ∨ 1 ≤ |γ−R|. have habs : |(|t| − |γ|)| ≥ |(|γ| − R)| − |(|t| − R)| — via the abs_sub chain: |(|γ|−R)| ≤ |(|γ|−|t|)| + |(|t|−R)| (abs_sub_le: |x−z| ≤ |x−y|+|y−z| with x := |γ|, y := |t|, z := R: |(|γ|−R)| ≤ |(|γ|−|t|)|+|(|t|−R)| ✓) and |(|γ|−|t|)| = |(|t|−|γ|)| (abs_sub_comm). Then: ||t|−|γ|| ≥ ||γ|−R| − ||t|−R|: ||t|−R| = R−|t| (|t| ≤ R: abs_im_le_norm + hs: abs_of_nonpos...) hmm: ||t|−R|: |t| ≤ R ⟹ |t|−R ≤ 0 ⟹ ||t|−R| = R−|t| ✓ abs_of_nonpos. And |t−γ| ≥ ||t|−|γ|| (abs_abs_sub_abs_le_abs_sub : |(|a|−|b|)| ≤ |a−b| — need the name. `abs_abs_sub_abs_le_abs_sub` — I used this name in design; check: in Mathlib it's `abs_abs_sub_abs_le_abs_sub : |(|a| − |b|)| ≤ |a − b|` ✓ I believe.) And ||γ|−R| ≥ 1/(16Ĉ): from hgap': case 1/(16Ĉ) ≤ |γ−R|: |γ−R| = ||γ|−R|?? γ could be negative: |γ−R| vs ||γ|−R|: if γ ≥ 0: equal. If γ < 0: |γ−R| = |γ|+R (γ−R < 0: |γ−R| = R−γ = R+|γ|) and ||γ|−R| = ||γ|−R| = |γ|+R... wait |γ|−R: |γ| ≥ 0, could be < R: ||γ|−R| = R−|γ| if |γ| ≤ R or |γ|−R if |γ| > R. For γ < 0: |γ−R| = R+|γ| (since γ−R < 0, |γ−R| = −(γ−R) = R−γ = R+|γ| ✓). And ||γ|−R|: hmm these differ: |γ−R| = R+|γ| vs ||γ|−R| = |R−|γ||. NOT equal in general! E.g. γ = −1, R = 100: |γ−R| = 101, ||γ|−R| = 99. So hgap's bound on |γ−R| doesn't directly bound ||γ|−R| for negative γ. BUT for γ < 0: ||γ|−R| = |R−|γ|| — is that large? |γ| ≥ ‖ρ‖−1 ≥ R−3 (the crit shell zeros) ⟹ ||γ|−R| ≤ 3 possibly small! E.g. γ = −R+1: ||γ|−R| = 1. Hmm — but that's the distance of |γ| from R, and |γ| ∈ (R−3, R+3): ||γ|−R| ≤ 3: the gap property hgap gives |γ−R| ≥ 1/(16Ĉ) or ≥ 1 — for γ < 0, |γ−R| = |γ|+R ≥ R ≥ 1 ✓ second disjunct — tells us nothing about ||γ|−R|. WAIT — but for the crit arc bound, I need |t−γ| large where t = s.im can have EITHER sign. If γ < 0 and t < 0: |t−γ| = ||t|−|γ|| could be small if both ≈ −R... but then ρ' = conj ρ has im = −γ > 0 with ||γ|−R| small... The hgap property applied to CONJ ρ! hgap is universal over all nontrivial zeros: apply it to (starRingEnd ℂ) ρ (nontrivial via isNontrivialZero_conj): |−γ−R| = |γ+R| ≥ 1/(16Ĉ) or ≥ 1. For γ < 0: |γ+R| = ||γ|−R|·... γ+R: if γ ∈ (−R−3, −R+3): γ+R ∈ (−3, 3): |γ+R| = |γ−(−R)| hmm |γ+R| = ||γ|... γ = −|γ|: γ+R = R−|γ|: |γ+R| = |R−|γ|| = ||γ|−R|·... |R−|γ|| = ||γ|−R| ✓ (abs_sub_comm). So for γ < 0: hgap (conj ρ) gives ||γ|−R| ≥ 1/(16Ĉ) or ≥ 1 ✓. For γ ≥ 0: hgap ρ directly: |γ−R| = ||γ|−R| (γ = |γ|) ✓.

Fingers crossed; if nlinarith struggles, decompose manually. Let me also handle the filter-congruence lemmas for the assembly pieces. For piece3: ``` have hpiece3 : (F.filter (fun ρ => ¬ ‖(ρ:ℂ)‖ ≤ 3)).filter (fun ρ => ¬ ‖(ρ:ℂ)‖ ≤ R/2) |>.filter ... ``` Hmm — actually the cleanest: prove for each piece the filter EQUALITY via ext: ``` have he3 : F.filter (fun ρ => ¬‖(ρ:ℂ)‖ ≤ 3 ∧ ¬‖(ρ:ℂ)‖ ≤ R/2 ∧ ‖(ρ:ℂ)‖ ≤ R−2) = F.filter (fun ρ => ¬‖(ρ:ℂ)‖ ≤ R/2 ∧ ‖(ρ:ℂ)‖ ≤ R−2) := by ext ρ simp only [Finset.mem_filter] constructor · intro h; exact ⟨h.2⟩ · intro h refine ⟨⟨?_, h.1⟩, h.2⟩... ``` wait — shell_inhi's finset: F.filter (fun ρ => ¬‖ρ‖ ≤ R/2 ∧ ‖ρ‖ ≤ R−2): mem ↔ ρ ∈ F ∧ (¬‖ρ‖ ≤ R/2 ∧ ‖ρ‖ ≤ R−2). The iterated piece: F.filter (¬P1 ∧ ¬P2 ∧ P3): mem ↔ ρ ∈ F ∧ (¬P1 ∧ ¬P2 ∧ P3)... hmm the AND-nesting from filter_filter: filter P3 (filter (¬P1 ∧ ¬P2) F)?? — the iterated: ((F.filter ¬P1).filter ¬P2).filter P3: filter_filter says filter p (filter q s) = filter (fun a => q a ∧ p a) s — applied twice: (F.filter ¬P1).filter ¬P2 = filter (¬P1 ∧ ¬P2) F; then filter P3 of THAT: = filter (fun a => (¬P1 a ∧ ¬P2 a) ∧ P3 a) F. So the predicate is (¬P1 ∧ ¬P2) ∧ P3 — the equality to shell_inhi's (¬P2 ∧ P3): ext + tauto with the bound: ¬P2 ∧ P3 ⟹ ¬P1 (‖ρ‖ > R/2 ≥ 8001 > 3 ⟹ ¬(‖ρ‖ ≤ 3) ✓ linarith). OK. Rather than perfect foresight, write it and iterate. Also — the `F.filter` lambdas must pin the binder type (banked gotcha) — the shell lemmas' finsets all have pinned lambdas; the assembly's filter predicates must be SYNTACTICALLY IDENTICAL for the congruence/sum_filter lemmas to rewrite. The iterated split produces predicates built from P1..P4 as I write them — I'll write the split with exactly the shell lambdas: - P1-lambda: (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ‖(ρ:ℂ)‖ ≤ 3) ✓ = shell_low's. - inlo: (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬‖(ρ:ℂ)‖ ≤ 3 ∧ ‖(ρ:ℂ)‖ ≤ R/2) ✓ shell_inlo's. - inhi: (¬‖·‖ ≤ R/2 ∧ ‖·‖ ≤ R−2) ✓. - crit: (¬‖·‖ ≤ R−2 ∧ ‖·‖ < R+2) ✓. - up: (¬‖·‖ < R+2) ✓. The sum_filter_add_sum_filter_not with explicit (p := ...) — the decidability instance: with `classical` in scope, fine. The five-way split chain: let me define the split as a have: ``` have hsplit5 : ∑ ρ ∈ F, g ρ = ∑ ρ ∈ F.filter q1, g ρ + (∑ ρ ∈ F.filter q2, g ρ + (∑ ρ ∈ F.filter q3, g ρ + (∑ ρ ∈ F.filter q4, g ρ + ∑ ρ ∈ F.filter q5, g ρ))) ``` where q1 = low-pred, q2 = inlo-pred (¬q1' ∧ ·), q3 = inhi-pred, q4 = crit-pred, q5 = up-pred, with q1' := (‖·‖ ≤ 3) etc. Hmm — the sum_filter_add_sum_filter_not splits by p = (‖·‖ ≤ 3): filter p + filter ¬p. ¬p as a lambda: (fun ρ => ¬‖ρ‖ ≤ 3) — then filter P2 on it = filter (fun ρ => ¬‖ρ‖ ≤ 3 ∧ ‖ρ‖ ≤ R/2) via filter_filter ✓ = q2 ✓ directly! Great — so piece2 IS q2 (shell_inlo's finset) with no congruence needed. piece3: (F.filter (¬p1)).filter (¬p2')... wait the split of filter ¬p1 by p2' := (‖·‖ ≤ R/2): = filter (¬p1 ∧ p2') + filter (¬p1 ∧ ¬p2') ✓ first = q2 ✓. Then split filter (¬p1 ∧ ¬p2') by p3' := (‖·‖ ≤ R−2): filter ((¬p1 ∧ ¬p2') ∧ p3') + filter ((¬p1 ∧ ¬p2') ∧ ¬p3'): first = filter (fun ρ => (¬‖ρ‖≤3 ∧ ¬‖ρ‖≤R/2) ∧ ‖ρ‖≤R−2) — vs shell_inhi's q3 = (¬‖ρ‖≤R/2 ∧ ‖ρ‖≤R−2): congruence needed (drop ¬p1, regroup). piece4: split by p4' := (‖·‖ < R+2): filter (((¬p1∧¬p2')∧¬p3') ∧ p4') + filter (((¬p1∧¬p2')∧¬p3')∧¬p4'): congr to q4 = (¬p3' ∧ p4') and q5 = ¬p4'. So 3 congruences (piece3 → q3, piece4 → q4, piece5 → q5). Each ~8 lines (ext, simp [mem_filter], tauto with linarith for the drop). Alright — let me write shell_crit + the helper + assembly in one go. Actually, given the size, let me do shell_crit first (compile), then assembly.
3c-ii committed. Now the critical shell with the arc analysis, plus a factored helper for the R−|im| bound.

Several errors: 1. **Line 2594 (h5)**: linarith failed to combine the abs chain. The goal: `1/(32Ĉ) ≤ |s.im − ρ.im|`. Available: hγR : 1/(16Ĉ) ≤ ||γ|−R|; h2 : ||γ|−R| ≤ ||γ|−|t|| + ||t|−R|; h3 : ||γ|−|t|| = ||t|−|γ||; h4 : ||t|−R| = R−|t|; h1 : ||t|−|γ|| ≤ |t−γ|; hRt : R−|t| ≤ 13/R; hthr : 13/R ≤ 1/(32Ĉ). The desired: |t−γ| ≥ ||t|−|γ|| (h1) ≥ ||γ|−R| − ||t|−R| (from h2+h3) = ||γ|−R| − (R−|t|) (h4) ≥ 1/(16Ĉ) − 13/R (hγR, hRt) ≥ 1/(16Ĉ) − 1/(32Ĉ) (hthr) = 1/(32Ĉ). All linear in the abs-ATOMS — linarith should do this... The problem: the atoms have NESTED abs bars that might not be syntactically aligned: h2's `||(↑ρ).im| - R|` vs hγR's `||(↑ρ).im| - R|` — same ✓. h3 : `||γ| − |t|| = ||t| − |γ||` ✓ h1's `||s.im| − |γ||` ✓ hmm wait — h1 : |(|s.im| − |γ|)| ≤ |s.im − γ| and h3 : |(|γ|−|t|)| = |(|s.im|−|γ|)| — wait h3 as displayed: `|| (↑ρ).im| - |s.im|| = ||s.im| - |(↑ρ).im||` ✓ matches h1's LHS ✓. And h4 : `||s.im| − R| = R − |s.im|` ✓ matches h2's second term ✓. So all atoms: A := ||γ|−R|, B := ||t|−|γ||, C := |t−γ|, D := R−|t|. h2: A ≤ B' + ||t|−R| with B' := ||γ|−|t||, h3: B' = B, h4: ||t|−R| = D, h1: B ≤ C, hγR: A ≥ 1/(16Ĉ), hRt: D ≤ 13/R, hthr: 13/R ≤ 1/(32Ĉ). Chain: C ≥ B = B' ≥ A − ||t|−R| = A − D ≥ 1/(16Ĉ) − 13/R ≥ 1/(16Ĉ)−1/(32Ĉ) = 1/(32Ĉ). All linear — linarith [hγR, h1, h2, h3, h4, hRt, hthr] SHOULD work... unless the display vs actual terms differ: h2's `||s.im| - R|` — displayed as `||s.im| - R|` in h2 but h4 : `||s.im| - R)| = R - |s.im|` ✓ same. Hmm — wait, the issue might be the GOAL form: the goal after my have h5 is `1/(32·Ĉ) ≤ |s.im − ρ.im|` but the error's goal shown is `False` with a✝ : |s.im − ρ.im| < 1/(32Ĉ) — that's linarith's by_contra form ✓ normal. So linarith just couldn't chain... OH WAIT. I see it — the `linarith [hγR, h1, h2, h3, h4, hRt, hthr]` — h2 has THREE bars terms, and the combination requires substituting h3 and h4 (EQUALITIES) — linarith uses equalities fine. Hmm, but actually — let me recheck: is h3 stated backwards? abs_sub_comm a b : |a − b| = |b − a|. h3 : |(|γ| − |t|)| = |(|t| − |γ|)| := abs_sub_comm _ _ ✓. Then h2 : A ≤ B' + ||t|−R|, so A − ||t|−R| ≤ B' = B ≤ C: A − ||t|−R| ≤ C: with h4: ||t|−R| = D = R−|t|: C ≥ A − D. hγR : A ≥ 1/(16Ĉ), hRt : D ≤ 13/R ≤ 1/(32Ĉ): C ≥ 1/(16Ĉ) − 1/(32Ĉ) = 1/(32Ĉ) ✓ linear. linarith should close. UNLESS the division atoms differ: hthr's `13 / R` vs hRt's `13 / R` ✓ same. hγR's `1 / (16 * C0hat ...)` vs goal `1 / (32 * C0hat ...)` — different constants, fine linear. Hmm hold on — maybe the problem: `h1 : ||s.im| - |(↑ρ).im|| ≤ |s.im - (↑ρ).im|` — the GOAL's C is `|s.im - (↑ρ).im|` ✓ matches. Actually — wait. The linarith call I wrote was `linarith [hγR, h1, h2, h3, h4, hRt, hthr]` at h5. The error IS at 2594 — which line is that? It's the h5's linarith. Hmm let me count: the failure shows exactly these hypotheses in context ending with a✝ — yes h5's linarith failed. Why?! OH. I see it now! h2 : `|(|γ| − R)| ≤ |(|γ| − |t|)| + |(|t| − R)|` — abs_sub_le : |a − c| ≤ |a − b| + |b − c| — I applied `abs_sub_le _ _ _` with a := |γ|, b := |t|, c := R: |(|γ| − R)| ≤ |(|γ| − |t|)| + |(|t| − R)| ✓ that's what's displayed ✓. Hmm so h2 is right... Wait, actually — look VERY carefully at h4: `||s.im| - R)| = R - |s.im|` — hmm in the context display: `h4 : ||s.im| - R| = R - |s.im|` ✓. Hmm, so why did linarith fail?! Let me look at hRt : `R - |s.im| ≤ 13 / R` ✓ and hthr : `13 / R ≤ 1/(32·Ĉ)` ✓. A − D ≥ 1/(16Ĉ) − 1/(32Ĉ): C ≥ B = B' ≥ A − ||t|−R| = A − D. So C ≥ A − D ≥ 1/(16Ĉ) − 1/(32Ĉ) = 1/(32Ĉ). Yes linear, all atoms distinct. linarith SHOULD work. Unless... the equalities h3, h4 get used by linarith — yes it uses them. Hmm wait — maybe the issue is `1 / (32 * C0hat ...)` vs the GOAL in h5: I wrote `1 / (32 * C0hat (4 * (k : ℝ) + 9 / 2)) ≤ |s.im - (ρ : ℂ).im|` ✓. Let me look once more at the displayed context... `h2 : ||(↑ρ).im| - R| ≤ ||(↑ρ).im| - |s.im|| + ||s.im| - R|` ✓. `h3 : ||(↑ρ).im| - |s.im|| = ||s.im| - |(↑ρ).im||` ✓. `h1 : ||s.im| - |(↑ρ).im|| ≤ |s.im - (↑ρ).im|` ✓. `h4 : ||s.im| - R| = R - |s.im|` ✓. `hγR : 1 / (16 * C0hat ...) ≤ ||(↑ρ).im| - R|` ✓. `hRt : R - |s.im| ≤ 13 / R` ✓ `hthr : 13 / R ≤ 1 / (32 * C0hat ...)` ✓. The chain in raw terms: from h2: ||γ|−R| − ||t|−R| ≤ ||γ|−|t||. linarith processes: h2 gives ||γ|−R| ≤ ||γ|−|t|| + ||t|−R|. With h3 (eq): ||γ|−|t|| = ||t|−|γ||. With h4 (eq): ||t|−R| = R−|t|. So ||γ|−R| ≤ ||t|−|γ|| + (R−|t|) ⟹ ||t|−|γ|| ≥ ||γ|−R| − (R−|t|). With h1: |t−γ| ≥ ||t|−|γ|| ≥ ||γ|−R| − (R−|t|) ≥ 1/(16Ĉ) − 13/R (hγR, hRt) ≥ 1/(16Ĉ) − 1/(32Ĉ) (hthr) = 1/(32Ĉ). This is genuinely linear! Why did linarith fail?? OHHH — I bet the problem: hRt's statement is `R − |s.im| ≤ 13 / R` and h4's RHS is `R − |s.im|` — SAME atom ✓ fine... Hmm, wait — maybe the problem is h5 was stated as `1 / (32 * C0hat ...) ≤ |s.im - (ρ : ℂ).im|` but the GOAL (in hsep) is `1 / (32 * C0hat ...) ≤ ‖s − (ρ:ℂ)‖` — h5 is about |s.im − ρ.im|, then h6/h7 bridge to the norm ✓ that's later. Let me just try again with explicit intermediate haves instead of one big linarith — more robust: ``` have hb1 : |(|(ρ : ℂ).im| - R)| - (R - |s.im|) ≤ |s.im - (ρ : ℂ).im| := by linarith [h1, h2, h3, h4] have h5 : 1 / (32 * C0hat (4 * (k : ℝ) + 9 / 2)) ≤ |s.im - (ρ : ℂ).im| := by linarith [hγR, hRt, hthr, hb1] ``` Hmm — hb1 needs the same chain minus the constants: ||γ|−R| − (R−|t|) ≤ |t−γ|: from h2: A ≤ B' + ||t|−R|; h3: B' = B; h4: ||t|−R| = R−|t|; h1: B ≤ C: A − (R−|t|) ≤ B ≤ C ✓ linear ✓. If that still fails there's something syntactic I'm missing. Possibility: `abs_sub_le` in this Mathlib might have signature (a b c : α) : |a − c| ≤ |a − b| + |b − c| ✓ standard. And abs_sub_comm : |a − b| = |b − a| ✓. Hmm wait — actually maybe the real issue: in h5's linarith, the DIVISION terms: `1/(16*C0hat...)` and `1/(32*C0hat...)` — linarith treats `1/(16*C0hat...)` as an atom ✓ fine, and 1/(16Ĉ) − 1/(32Ĉ) = 1/(32Ĉ) — linarith needs to verify x − y = z with x := 1/(16Ĉ), y := z := 1/(32Ĉ): x = 2y: is `1/(16*Ĉ)` normalized to `2*(1/(32*Ĉ))`? NO — as atoms they're DIFFERENT terms: 1/(16·Ĉ) ≠ 1/(32·Ĉ) syntactically, and linarith's preprocessing turns division-by-products into... linarith does handle division by treating `1/(16*C0hat(4*↑k+9/2))` — hmm, the term contains the VARIABLE k inside C0hat(...) — so 1/(16·C0hat(...)) is an opaque atom P and 1/(32·C0hat(...)) is another opaque atom Q, and linarith does NOT know P = 2Q!! THAT'S the failure — the arithmetic relation between the two reciprocal atoms is invisible. In hthr I bridged 13/R ≤ Q explicitly ✓, but the final step needs 1/(16Ĉ) − 1/(32Ĉ) = 1/(32Ĉ), i.e., P − Q = Q, i.e., P = 2Q — INVISIBLE to linarith! Fix: prove `h16 : 1/(16*Ĉ) = 2 * (1/(32*Ĉ))` by `field_simp; ring` (Ĉ > 0) then linarith [h16, ...]. Or give hγR directly in the form ≥ 2/(32Ĉ). Let me add: ``` have hP2Q : 1 / (16 * C0hat (4 * (k : ℝ) + 9 / 2)) = 2 * (1 / (32 * C0hat (4 * (k : ℝ) + 9 / 2))) := by field_simp ring ``` field_simp needs Ĉ ≠ 0 — hĈpos available... field_simp uses hypotheses? Provide: `field_simp [hĈpos.ne']`? The denominators 16*Ĉ and 32*Ĉ — field_simp might need the ne facts: `have hĈne : C0hat (4*(k:ℝ)+9/2) ≠ 0 := hĈpos.ne'` then field_simp [hĈne]. Hmm field_simp [hĈne] then ring. 2. **Line 2628 (h2 in the near-axis case)**: "Unknown identifier hρ" — in the near-axis case (second branch of by_cases hre13), I reference... looking at my code: the second branch uses hsqrt, h3le, h1, hreρ, h2 — `have h2 : (2 : ℝ) < |s.re - (ρ : ℂ).re| := by linarith [hsqrt, h3le, h1, hreρ]` — no hρ there. Line 2628:25 — let me count... The `hsepρ := hsep ρ hρ` line in hterm! `hsep ρ hρ` — wait hterm's intro: `intro ρ hρ` then `rw [hFS, Finset.mem_filter] at hρ` then `obtain ⟨-, hρRm2, hρRp2⟩ := hρ` — hρ is CONSUMED by obtain. Then `have hsepρ := hsep ρ hρ` — hρ no longer exists! Fix: capture before obtain: reorder — `have hsepρ := hsep ρ hρ` BEFORE the rw/obtain: ``` intro ρ hρ have hsepρ := hsep ρ hρ rw [hFS, Finset.mem_filter] at hρ obtain ⟨-, hρRm2, hρRp2⟩ := hρ ``` Same bug pattern in hcount's hsub? hsub: `intro ρ hρ; rw [hFS, Finset.mem_filter] at hρ; obtain ...` — hsep isn't used there ✓. But check hterm: yes needs the reorder. 3. **Line 2640 (hden's positivity)**: `mul_le_mul hρRm2'.le hsepρ (by positivity) (by linarith [hR])` — the third arg: 0 ≤ 1/(32·Ĉ): positivity can't prove (C0hat is a def with log — positivity might unfold? "failed to prove positivity"). Fix: `(by positivity : (0:ℝ) ≤ 1/(32*C0hat...))` fails; use `div_nonneg one_pos.le (by linarith [hĈ2] : (0:ℝ) ≤ 32*C0hat...)`. Explicit: `div_nonneg one_pos.le (mul_nonneg (by norm_num : (0:ℝ) ≤ 32) hĈpos.le)`. 4. **Line 2645 "No goals"**: h2's `field_simp; ring` — field_simp closed; remove ring. That's h2 : R/((R−2)·(1/(32Ĉ))) = 32Ĉ·(R/(R−2)): field_simp closed it → drop ring. Let me apply all fixes.
Four fixes: the reciprocal-atoms P=2Q bridge, `hρ` consumed before `hsep`, a positivity failure, and a stray `ring`.

shell_crit compiles. Now the final assembly theorem.

The shell finsets: - shell_low's: F.filter (fun ρ : ST => ‖(ρ:ℂ)‖ ≤ 3) = F.filter q1 ✓ (q1 defined as that lambda ✓ defeq). - shell_inlo's: F.filter (fun ρ : ST => ¬‖(ρ:ℂ)‖ ≤ 3 ∧ ‖(ρ:ℂ)‖ ≤ R/2): from split of F.filter (¬q1) by q2: (F.filter (¬q1)).filter q2 = F.filter (fun ρ => ¬q1 ρ ∧ q2 ρ) (Finset.filter_filter) ✓ matches (¬‖ρ‖≤3 ∧ ‖ρ‖≤R/2) ✓ defeq. - shell_inhi's: F.filter (¬‖ρ‖ ≤ R/2 ∧ ‖ρ‖ ≤ R−2): the iterated piece is F.filter ((¬q1 ∧ ¬q2) ∧ q3) — congruence. - shell_crit's: F.filter (¬‖ρ‖ ≤ R−2 ∧ ‖ρ‖ < R+2): piece F.filter (((¬q1 ∧ ¬q2) ∧ ¬q3) ∧ q4) — congruence. - shell_up's: F.filter (¬‖ρ‖ < R+2): piece F.filter (((¬q1 ∧ ¬q2) ∧ ¬q3) ∧ ¬q4) — congruence. The congruences (filter ext with the R-bounds): ``` have hc3 : F.filter (fun ρ => (¬ q1 ρ ∧ ¬ q2 ρ) ∧ q3 ρ) = F.filter (fun ρ => ¬ q2 ρ ∧ q3 ρ) := by ext ρ simp only [Finset.mem_filter, hq1, hq2, hq3] constructor · intro h; exact ⟨⟨h.2.1.2?... ``` Hmm — with set-defined q1..q4, simp only [Finset.mem_filter, hq1, hq2, hq3] unfolds the predicates ✓. Then the membership forms: LHS: ρ ∈ F ∧ ((¬‖ρ‖≤3 ∧ ¬‖ρ‖≤R/2) ∧ ‖ρ‖≤R−2); RHS: ρ ∈ F ∧ (¬‖ρ‖≤R/2 ∧ ‖ρ‖≤R−2). Forward: drop. Backward: need ¬‖ρ‖≤3 from ¬‖ρ‖≤R/2: ‖ρ‖ > R/2 ≥ 8001 > 3: linarith [hR]. Structure: ``` constructor · rintro ⟨hF, ⟨h1, h2⟩, h3⟩ exact ⟨hF, h2, h3⟩ · rintro ⟨hF, h2, h3⟩ refine ⟨hF, ⟨?_, h2⟩, h3⟩ have hρ : R / 2 < ‖(ρ : ℂ)‖ := lt_of_not_ge h2 exact lt_of_not_ge... goal ¬‖ρ‖ ≤ 3: · exact fun h => by linarith [hρ, hR] -- hmm: ¬‖ρ‖≤3 ⟺ fun (h : ‖ρ‖≤3) => False: linarith ``` `exact fun h => by linarith [hρ, hR, h]` — or `exact not_le_of_gt (by linarith [hρ, hR] : (3:ℝ) < ‖(ρ:ℂ)‖)`. Similarly hc4: LHS ((¬q1∧¬q2)∧¬q3)∧q4 → (¬q3 ∧ q4): drop: ¬q3 gives ‖ρ‖ > R−2 > 3 and > R/2 ✓ linarith. hc5: → ¬q4: drop: ¬q4 gives ‖ρ‖ ≥ R+2 > R−2, R/2, 3 ✓. The assembling: ``` have hsplit2 : ∑ ρ ∈ F.filter (fun ρ => ¬ q1 ρ), g ρ = ∑ ρ ∈ (F.filter (fun ρ => ¬ q1 ρ)).filter q2, g ρ + ∑ ρ ∈ (F.filter (fun ρ => ¬ q1 ρ)).filter (fun ρ => ¬ q2 ρ), g ρ := Finset.sum_filter_add_sum_filter_not _ q2 g have hff2 : (F.filter (fun ρ => ¬ q1 ρ)).filter q2 = F.filter (fun ρ => ¬ q1 ρ ∧ q2 ρ) := Finset.filter_filter _ _ _ ``` Careful — Finset.filter_filter : (s.filter p).filter q = s.filter (fun a => p a ∧ q a) — direction: filter q (filter p s) = filter (fun a => p a ∧ q a) s ✓. So (F.filter ¬q1).filter q2 = F.filter (fun ρ => (¬q1 ρ) ∧ q2 ρ) ✓. This is getting verbose. Alternative: do the whole partition via a single big have using the 5-way split lemma I prove inline: Actually, simplest robust structure — compute step by step with rw [hsplit1, hsplit2, ...] and congruences as rewrites: ``` have hsplit : ∑ ρ ∈ F, g ρ = (((∑ ρ ∈ F.filter q1, g ρ) + ∑ ρ ∈ F.filter (fun ρ => ¬q1 ρ ∧ q2 ρ), g ρ) + ∑ ρ ∈ F.filter (fun ρ => ¬q2 ρ ∧ q3 ρ), g ρ) + (∑ ρ ∈ F.filter (fun ρ => ¬q3 ρ ∧ q4 ρ), g ρ + ∑ ρ ∈ F.filter (fun ρ => ¬ q4 ρ), g ρ) := ... ``` The association/nesting: split1: S = S1 + T1 where T1 = ∑_{filter ¬q1}. split2: T1 = S2 + T2 where S2 = ∑_{filter (¬q1∧q2)} — wait (F.filter ¬q1).filter q2 = F.filter(¬q1 ∧ q2) ✓ and T2 = ∑_{(F.filter ¬q1).filter ¬q2} = ∑_{F.filter (¬q1∧¬q2)}. split3: T2 = S3 + T3, S3 = ∑_{(F.filter (¬q1∧¬q2)).filter q3} = ∑_{F.filter ((¬q1∧¬q2)∧q3)} =[hc3]= ∑_{F.filter (¬q2∧q3)}. T3 = ∑_{F.filter ((¬q1∧¬q2)∧¬q3)}. split4: T3 = S4 + S5: S4 = ∑_{filter (((¬q1∧¬q2)∧¬q3)∧q4)} =[hc4]= ∑_{F.filter (¬q3∧q4)}; S5 = ∑_{filter (((¬q1∧¬q2)∧¬q3)∧¬q4)} =[hc5]= ∑_{F.filter ¬q4}. Then S ≤ S1 + S2 + S3 + S4 + S5 ≤ 2·lowZeroConst + 60A₀L² + 60A₀L² + 2688ĈA₀L + 45A₀L² and the tail 91A₀L. The shell applications: shell_low hs hsz hR — its finset: (circleZeros R).filter (fun ρ : ST => ‖(ρ:ℂ)‖ ≤ 3) — F.filter q1: is F.filter q1 DEFEQ to that? F := circleZeros R (set alias), q1 := (fun ρ => ‖(ρ:ℂ)‖ ≤ 3) (set alias) — after `set`, occurrences are replaced by the aliases: shell_low's statement has the unfolded forms... When I `have h1 := shell_low hs hsz hR`, h1's type displays with circleZeros R and the lambda — matching F.filter q1 requires unfolding the set aliases. `set ... with hF` introduces hF : F = circleZeros R — I can `rw [hF] at ...` hmm — set replaces occurrences of circleZeros R in the GOAL by F; hypotheses h1 keep circleZeros R. Then ∑ ρ ∈ F.filter q1, g ρ vs h1's ∑ ρ ∈ (circleZeros R).filter (fun ρ => ‖(ρ:ℂ)‖ ≤ 3), ‖seriesTerm s ρ‖: to use h1 as a bound for the first piece, I need the pieces stated in the shell's unfolded form. Simplest: DON'T use set for F/g/q1..q4 — write everything unfolded (verbose but no mismatch). The g alias: shell lemmas give bounds on ∑ ‖seriesTerm s ρ‖ directly — keep g := fun ρ => ‖seriesTerm s ρ‖ as a plain lambda everywhere (no set). OK let me write it fully unfolded. The predicates as plain lambdas with pinned binder types. The sum_filter_add_sum_filter_not applications with explicit p: ``` have hsplit1 : ∑ ρ ∈ circleZeros R, (fun ρ => ‖seriesTerm s ρ‖) ρ = ∑ ρ ∈ (circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ‖(ρ : ℂ)‖ ≤ 3), (fun ρ => ‖seriesTerm s ρ‖) ρ + ∑ ρ ∈ (circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ 3), (fun ρ => ‖seriesTerm s ρ‖) ρ := Finset.sum_filter_add_sum_filter_not _ _ _ ``` Hmm — the summand in seriesFun_norm_le_split is `‖seriesTerm s ρ‖` (an application, not a lambda-applied). tsum_split_finset gave: ∑ ρ ∈ circleZeros R, ‖seriesTerm s ρ‖ — the elaborated form is ∑ ρ ∈ circleZeros R, (fun ρ => ‖seriesTerm s ρ‖) ρ — the display is the application. sum_filter_add_sum_filter_not _ _ _ should unify (the p gets inferred from... the goal — since I'm ascribing hsplit1's type, unification pins p := (fun ρ : ST => ‖ρ‖ ≤ 3) ✓). Then the shell bound applications: shell_low hs hsz hR : ∑ ρ ∈ (circleZeros R).filter (fun ρ : ST => ‖(ρ:ℂ)‖ ≤ 3), ‖seriesTerm s ρ‖ ≤ 2·lowZeroConst — the summand there is ‖seriesTerm s ρ‖ — application vs (fun ρ => ...)ρ — defeq (beta) ✓ linarith can bridge? For the final linarith I'll pass the shell bounds as haves; linarith sees the sum terms as atoms — the atoms must be SYNTACTICALLY equal for linarith to match! The beta-redex vs reduced application: linarith normalizes via... linarith uses syntactic atom matching up to reducible defeq — beta-redexes might not match! Banked gotcha from session 031: "state split goals with `show` in reduced form" — the summand beta-redex issue. To be safe: beta-reduce the pieces with `show` or `simp only []`... The cleanest: after establishing hsplit (the partition identity with the pieces in whatever form), convert with `conv` to beta-reduce... Alternatively state hsplit with the summand ALREADY as application: sum_filter_add_sum_filter_not's conclusion has f applied — with f := fun ρ => ‖seriesTerm s ρ‖ the terms are (fun ρ => ...) ρ — beta-redexes. If instead I apply sum_filter_add_sum_filter_not with f := (fun ρ => ‖seriesTerm s ρ‖) — same thing. The Finset.sum notation: ∑ ρ ∈ s, f ρ — the pretty printer shows ‖seriesTerm s ρ‖ when f is the lambda (it eta-reduces? The sum is over `(fun ρ => ‖seriesTerm s ρ‖)` — displayed as ∑ ρ ∈ s, ‖seriesTerm s ρ‖). Shell lemmas' sums are over the same lambda — same atoms ✓. I think it's fine since both come from the same syntactic source. Just be consistent: everywhere use the summand `‖seriesTerm s ρ‖` and let Lean unify. For hsplit's pieces after filter_filter rewrites — the conjunction lambdas must match the shells' pinned lambdas exactly: - inlo: (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ 3 ∧ ‖(ρ : ℂ)‖ ≤ R / 2) ✓ copied from shell_inlo. - inhi: (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ R / 2 ∧ ‖(ρ : ℂ)‖ ≤ R - 2) ✓. - crit: (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ R - 2 ∧ ‖(ρ : ℂ)‖ < R + 2) ✓. - up: (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ < R + 2) ✓. The congruences hc3/hc4/hc5 rewrite the iterated pieces to these. The intermediate forms from filter_filter: (fun ρ => (fun ... ¬q1-ish) ρ ∧ ...) — hmm filter_filter gives filter (fun a => p a ∧ q a) with p,q the lambdas — the resulting lambda is (fun ρ => ¬‖(ρ:ℂ)‖ ≤ 3 ∧ ‖(ρ:ℂ)‖ ≤ R/2) — with the SAME binder type as the pieces? p := (fun ρ : ST => ¬‖(ρ:ℂ)‖ ≤ 3) — binder pinned ✓ then the conjunction lambda's binder : ST ✓ and the body ¬‖(ρ:ℂ)‖ ≤ 3 ∧ ‖(ρ:ℂ)‖ ≤ R/2 — should match shell_inlo's lambda syntactically if I write the filters with identical text. ✓ Now write the assembly: ```lean -- shells have hsh1 := shell_low hs hsz hR have hsh2 := shell_inlo hs hsz hR have hsh3 := shell_inhi hs hsz hR have hsh4 := shell_crit hk hRlo hgap hs hsz have hsh5 := shell_up hs hsz hR have htail := series_tail_le hs hR have hsplit0 := seriesFun_norm_le_split (s := s) (R := R) -- the partition identity have hsplit1 : ... := Finset.sum_filter_add_sum_filter_not (circleZeros R) (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ‖(ρ : ℂ)‖ ≤ 3) (fun ρ => ‖seriesTerm s ρ‖) have hsplit2 : ... (on the ¬q1 piece by q2) have hsplit3 : ... have hsplit4 : ... have hff2 : ((circleZeros R).filter (¬q1)).filter q2 = (circleZeros R).filter (¬q1 ∧ q2) := Finset.filter_filter _ _ _ ... have hc3 : (circleZeros R).filter (fun ρ : ST => (¬‖(ρ:ℂ)‖ ≤ 3 ∧ ¬‖(ρ:ℂ)‖ ≤ R/2) ∧ ‖(ρ:ℂ)‖ ≤ R−2) = (circleZeros R).filter (fun ρ : ST => ¬‖(ρ:ℂ)‖ ≤ R/2 ∧ ‖(ρ:ℂ)‖ ≤ R−2) := by ext... have hc4 : ... = crit's have hc5 : ... = up's ``` Then chain everything with linarith [hsplit0, htail, hsh1..5, hsplit1..4, hff2.., hc3..5, hfin]. Hmm — linarith with EQUALITIES of finset sums: the partition gives sum-equalities (S = S1 + T1 etc.); the shells give inequalities on the pieces; linarith combines linear ✓ as long as the atoms align. The pieces after rewriting via hff2/hc3/hc4/hc5 must be TEXTUALLY the shells' sums. Use rw to normalize the pieces in the split chain: Actually cleanest: build the full partition as one big have by successive rw: ``` have hpart : ∑ ρ ∈ circleZeros R, ‖seriesTerm s ρ‖ = (((∑ ρ ∈ (circleZeros R).filter (low), ‖seriesTerm s ρ‖ + ∑ ρ ∈ (circleZeros R).filter (inlo), ‖seriesTerm s ρ‖) + ∑ ρ ∈ (circleZeros R).filter (inhi), ‖seriesTerm s ρ‖) + ∑ ρ ∈ (circleZeros R).filter (crit), ‖seriesTerm s ρ‖) + ∑ ρ ∈ (circleZeros R).filter (up), ‖seriesTerm s ρ‖ := by rw [Finset.sum_filter_add_sum_filter_not (circleZeros R) (low) _, Finset.sum_filter_add_sum_filter_not _ (fun ρ : ST => ‖(ρ:ℂ)‖ ≤ R/2) _, Finset.sum_filter_add_sum_filter_not _ (fun ρ : ST => ‖(ρ:ℂ)‖ ≤ R−2) _, Finset.sum_filter_add_sum_filter_not _ (fun ρ : ST => ‖(ρ:ℂ)‖ < R+2) _] -- now the pieces are in filter-of-filter form; normalize with filter_filter + congruences rw [Finset.filter_filter, Finset.filter_filter, Finset.filter_filter, ...] -- then congruence rewrites hc3 hc4 hc5 rw [hc3, hc4, hc5] ``` The rewriting chain in a big goal — fragile (the filter predicates in the rw's must match). Alternative: establish the sum-chain via explicit haves and finish with linarith. That's more verbose but each step checkable. Let me do the haves + linarith approach: ``` have hsplit1 := Finset.sum_filter_add_sum_filter_not (circleZeros R) (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ‖(ρ : ℂ)‖ ≤ 3) (fun ρ => ‖seriesTerm s ρ‖) -- hsplit1 : ∑ F = ∑_{F.filter q1} + ∑_{F.filter (¬q1)} have hsplit2 := Finset.sum_filter_add_sum_filter_not ((circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ 3)) (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ‖(ρ : ℂ)‖ ≤ R / 2) (fun ρ => ‖seriesTerm s ρ‖) -- T1 = ∑_{(F.filter ¬q1).filter q2} + ∑_{(F.filter ¬q1).filter ¬q2} have hff2 : ((circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ 3)).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ‖(ρ : ℂ)‖ ≤ R / 2) = (circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ 3 ∧ ‖(ρ : ℂ)‖ ≤ R / 2) := Finset.filter_filter _ _ _ rw [hff2] at hsplit2 have hff2' : ((circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ 3)).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ R / 2) = (circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ 3 ∧ ¬ ‖(ρ : ℂ)‖ ≤ R / 2) := Finset.filter_filter _ _ _ rw [hff2'] at hsplit2 have hsplit3 := Finset.sum_filter_add_sum_filter_not ((circleZeros R).filter (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ¬ ‖(ρ : ℂ)‖ ≤ 3 ∧ ¬ ‖(ρ : ℂ)‖ ≤ R / 2)) (fun ρ : {ρ : ℂ // IsNontrivialZero ρ} => ‖(ρ : ℂ)‖ ≤ R - 2) (fun ρ => ‖seriesTerm s ρ‖) have hff3 : (...).filter (q3) = (circleZeros R).filter (fun ρ : ST => (¬‖ρ‖≤3 ∧ ¬‖ρ‖≤R/2) ∧ ‖ρ‖≤R−2) := Finset.filter_filter _ _ _ rw [hff3] at hsplit3 have hff3' : (...).filter (¬q3) = ...

So filter_filter's RHS predicate is (fun a => (¬‖(a:ℂ)‖ ≤ 3) ∧ (‖(a:ℂ)‖ ≤ R/2)) after beta — Lean's filter_filter statement: `theorem Finset.filter_filter (p q : α → Prop) [DecidablePred p] [DecidablePred q] (s : Finset α) : (s.filter p).filter q = s.filter fun a => p a ∧ q a` — the RHS has the lambda (fun a => p a ∧ q a) — with p,q the actual lambdas — beta-redex applications p a, q a. When I rw [hff2] at hsplit2 where hff2's RHS is my hand-written (fun ρ : ST => ¬‖(ρ:ℂ)‖ ≤ 3 ∧ ‖(ρ:ℂ)‖ ≤ R/2) — the rw [hff2] rewrites LHS-of-hff2 to RHS-of-hff2 in hsplit2 — hsplit2's piece is (F.filter ¬q1).filter q2 — matching hff2's LHS — the rw works by matching hff2's LHS pattern against hsplit2 ✓ replacing with hff2's RHS (my clean form) ✓. So the rw produces my clean lambda regardless of the redex form ✓ — as long as hff2's LHS matches hsplit2's piece textually. hff2 := Finset.filter_filter _ _ _ — its type: (s.filter ?p).filter ?q = s.filter (fun a => ?p a ∧ ?q a) — ascription matches LHS ✓. BUT: the rw [hff2] at hsplit2 — rw rewrites instances of hff2's LHS — the piece in hsplit2 — ✓. However — the DecidablePred instances: filter_filter needs [DecidablePred p] [DecidablePred q] — hsplit2's filters carry the classical instances (classical in scope) — unification handles ✓ hopefully. Also NOTE: hsplit2 as I stated it is Finset.sum_filter_add_sum_filter_not applied to (F.filter ¬q1) with p := q2: conclusion: ∑_{F.filter ¬q1} f = ∑_{(F.filter ¬q1).filter q2} f + ∑_{(F.filter ¬q1).filter (fun ρ => ¬ q2 ρ)} f — the second piece's predicate: (fun ρ : ST => ¬ ‖(ρ:ℂ)‖ ≤ R/2) ✓. OK — this is going to be long but mechanical. One more consideration: the final linarith combination needs hsplit0 (‖seriesFun‖ ≤ S + tail), hsplit1..4 (S = ..., T1 = ..., T2 = ..., T3 = S4+S5), the congruences applied, shells, htail, and the final constant absorption hfin (the nlinarith). The pieces' atoms: after all the rws at hsplit2/3/4, and hc3/hc4/hc5 — the congruences rewrite the SUM atoms: hc3 : filter(...) = filter(inhi-form) — rw [hc3] at hsplit3: hsplit3's S3-piece becomes the inhi-form sum ✓. Then: S = S1 + T1, T1 = S2 + T2, T2 = S3 + T3, T3 = S4 + S5 with S1..S5 exactly the shell sums (after rws) ⟹ S = S1+S2+S3+S4+S5 by linarith (equalities between sum atoms ✓). Then ‖seriesFun‖ ≤ S + tail ≤ (2·lowZeroConst + 60A₀L² + 60A₀L² + 2688ĈA₀L + 45A₀L²) + 91A₀L and hfin absorbs ≤ 2900A₀ĈL². hfin: 2*lowZeroConst + 60A₀L²+60A₀L²+2688ĈA₀L+45A₀L² + 91A₀L ≤ 2*lowZeroConst + 2900*A₀*Ĉ*L²: nlinarith [hĈ2, hlogR, hA0, hL2, lowZeroConst_nonneg] — hmm the L ≤ L² fact: hL2 : Real.log R ≤ (Real.log R)^2 := by nlinarith [hlogR] — wait that itself is nonlinear: L² ≥ L ⟸ L ≥ 9: nlinarith [hlogR]: goal L ≤ L² ⟺ 0 ≤ L(L−1): L ≥ 9 ⟹ L(L−1) ≥ 0: nlinarith does (L)·(L−1) hmm — nlinarith [hlogR] should: product of (L−9) and L: L² −9L ≥ 0 ⟹ L² ≥ 9L ≥ L ✓ via pairs. Actually: L ≤ L² ⟸ L² − L = L(L−1) ≥ 0: nlinarith considers L·L ≥ 9L (from hlogR multiplied by L ≥ 0?) — nlinarith multiplies hypotheses: hlogR·(L) hmm. nlinarith [hlogR] : proves L ≤ L^2? It needs: L² − L ≥ 0: try: (L − 9)·L ≥ 0 (from hlogR and L ≥ 0): nlinarith knows pow_two_nonneg? The term L^2 − L: with 9 ≤ L: L^2 ≥ 9L ≥ L... nlinarith proves: L^2 − L = L·(L−1): hmm it needs (L−1) ≥ 0 and L ≥ 0: products: hlogR (9 ≤ L) with itself: 81 ≤ L²; then L² ≥ 81 ≥ L ✓ since L ≥ 9 and 81 ≥ 9... L² ≥ 81 and L ≤ ... no: L ≥ 9 and L² ≥ 81 doesn't give L² ≥ L directly... it does: L² ≥ 81 ≥ L ⟸ L ≤ 81? NO L could be 100. Hmm: L² ≥ L ⟺ L ≥ 1 (L ≥ 0): L ≥ 9 ≥ 1 ✓: L·L ≥ 1·L = L: mul_le_mul_of_nonneg_left (1 ≤ L) (L ≥ 0)... nlinarith: L²−L ≥ 0 ⟸ (L−1)·L ≥ 0: nlinarith considers products of pairs among [hlogR] and atoms: (L−9)(L) — from hlogR: L−9 ≥ 0 and L ≥ ... nlinarith might need (L)(L−1) — the pair (L−1 ≥ 0) isn't a hypothesis but (L ≥ 9) implies it — nlinarith multiplies (hlogR : 9 ≤ L) by (hlogR): 81 ≤ L²: gives L² ≥ 81: and needs L² ≥ L: L² ≥ 81 and L ≥ 9 ⟹ L² ≥ 81 ≥ ... no: L ≥ 9 ⟹ L² ≥ 9L (L·L ≥ 9·L needs L ≥ 0 — the product (L)·(hlogR): nlinarith multiplies hypotheses by atoms: hlogR·L: 9L ≤ L² ✓ then L² ≥ 9L ≥ L ⟸ 9L ≥ L ⟸ L ≥ 0 ✓. So nlinarith [hlogR] proves L ≤ L² ✓ (it does multiply hypotheses by variables). Then the absorption nlinarith [hĈ2, hlogR, hA0, hL2]: goal: 165A₀L² + 2688ĈA₀L + 91A₀L ≤ 2900A₀ĈL². As computed: suffices: 2688ĈA₀L ≤ 2688ĈA₀L² (ĈA₀·(L²−L) ≥ 0) and 256A₀L² ≤ 212·2A₀L² ≤ 212ĈA₀L² hmm: 165+91 = 256: 256A₀L² ≤ 256·(Ĉ/2)A₀L² = 128ĈA₀L² (Ĉ ≥ 2) and 2688+128 = 2816 ≤ 2900 ✓. The nlinarith products: (Ĉ−2)·(A₀L²) ≥ 0; (L²−L)·(A₀) ≥ 0; (L²−L)·(ĈA₀) ≥ 0: nlinarith [hĈ2, hL2, hA0, mul_nonneg hA0 (pow_two_nonneg (Real.log R)), mul_nonneg (mul_nonneg hĈ2'... ] — Ĉ ≥ 0 from hĈ2: give hints: hnn1 : 0 ≤ A0count * (Real.log R)^2; hnn2 : 0 ≤ C0hat(...) * A0count. nlinarith [hĈ2, hlogR, hA0, hL2, hnn1, hnn2]. The key products: (Ĉ−2)·(A₀L²) — nlinarith multiplies (hĈ2 : 2 ≤ Ĉ) by hnn1 ✓; (L²−L)·(A₀) — hL2·... nlinarith multiplies hL2 by hA0?? It multiplies PAIRS of hypotheses (and their negations): hL2·hA0: A₀·(L²−L) ≥ 0 ✓. And 2688ĈA₀L ≤ 2688ĈA₀L²: ĈA₀·(L²−L): hL2·(ĈA₀): product of hL2 with hnn2 ✓. OK it should find it. If not, I'll decompose manually. Wait — also the 2·lowZeroConst appears on both sides: linarith cancels ✓. Let me now write the assembly. It's long; write carefully.
shell_crit compiles. Now the final assembly theorem with the iterated filter-split partition.

The `ext ρ` didn't split the goal into an Iff of memberships as expected — the errors show `Quot.lift (fun l => ρ ∈ l) ⋯ (circleZeros R).val` — the ext lemma applied was the WRONG one (some Quotient ext), or ext didn't fire correctly and my rintro/constructor structure mismatched. The goal after `ext ρ` should be `ρ ∈ LHS ↔ ρ ∈ RHS`. The error suggests `ext ρ` left something weird. Actually — looking at the error: `simp only [Finset.mem_filter]` then `constructor` — the goal might already be the Iff ✓ but then `rintro ⟨hF, ⟨-, h2⟩, h3⟩` — the membership of filter: ρ ∈ F ∧ pred — after simp only [mem_filter], the goal's LHS membership: `ρ ∈ circleZeros R ∧ pred ρ` — the rintro pattern ⟨hF, ⟨-, h2⟩, h3⟩ — pred is ((¬q1 ∧ ¬q2) ∧ q3): the And structure: ⟨hF, ⟨⟨h1, h2⟩, h3⟩⟩ — I wrote ⟨hF, ⟨-, h2⟩, h3⟩ which should parse as ⟨hF, ⟨⟨-, h2⟩, h3⟩⟩ ✓. Hmm — the errors are at the `exact ⟨⟨hF, h2⟩, h3⟩` lines: "expected type Quot.lift ... is not an inductive type" — the GOAL after rintro isn't the anonymous-constructor form — because `ext ρ` didn't produce the Iff! The `Quot.lift (fun l => ρ ∈ l) ⋯ (circleZeros R).val` — that's the `ρ ∈ circleZeros R` membership UNFOLDED (Finset membership via Quot). So after `ext ρ; simp only [Finset.mem_filter]`, the goal's two sides are Iff — but `constructor` on an Iff gives both directions ✓... The errors at 2819/2821 (the exact ⟨⟨hF, h2⟩, h3⟩ lines): the expected type shown is the Quot.lift membership — meaning the goal at that point is JUST `ρ ∈ circleZeros R ∧ ...`?? no... Wait — actually the issue: `ext ρ` may have applied `Finset.ext` giving `∀ ρ, ρ ∈ LHS ↔ ρ ∈ RHS` and after intro ρ... I did `ext ρ` — in Lean4 Mathlib, `ext ρ` on a Finset equality goal: applies Finset.ext then intro ρ ✓ goal: ρ ∈ LHS ↔ ρ ∈ RHS ✓. Then simp only [Finset.mem_filter] unfolds both sides ✓ then constructor splits the Iff ✓ then rintro pattern... The error "Invalid ⟨...⟩ notation: The expected type Quot.lift (fun l => ρ ∈ l) ⋯ (circleZeros R).val is not an inductive type" at the `exact ⟨⟨hF, h2⟩, h3⟩` — so at that point the goal IS `Quot.lift ...` — i.e., the goal is `ρ ∈ circleZeros R` UNPROCESSED — meaning my rintro consumed the And structure but the goal decomposed differently... OH WAIT. I see: after `simp only [Finset.mem_filter]`, maybe the Iff sides became `(ρ ∈ circleZeros R ∧ P1) ↔ (ρ ∈ circleZeros R ∧ P2)` and `constructor` — hmm constructor on Iff: `Iff.intro` needs BOTH mp and mpr — `constructor` gives two goals ✓. Then `rintro ⟨hF, ⟨-, h2⟩, h3⟩` on the mp direction: hypothesis is `ρ ∈ circleZeros R ∧ ((¬q1 ρ ∧ ¬q2 ρ) ∧ q3 ρ)` ✓ pattern works ✓. Goal: `ρ ∈ circleZeros R ∧ (¬q2 ρ ∧ q3 ρ)`: `exact ⟨⟨hF, h2⟩, h3⟩` — WAIT: ⟨hF, h2⟩ pairs hF with h2, then ⟨that, h3⟩ — but the goal's And is `ρ ∈ circleZeros R ∧ (¬q2 ∧ q3)`: needs ⟨hF, ⟨h2, h3⟩⟩! I wrote ⟨⟨hF, h2⟩, h3⟩ — WRONG nesting!! The error message's "expected type Quot.lift (fun l => ρ ∈ l)" — the FIRST component of the outer pair should be the membership proof hF, but I gave ⟨hF, h2⟩ a PAIR. So the anonymous constructor tried to make ⟨hF, h2⟩ : ρ ∈ circleZeros R — error ✓ explains it. Fix the nestings: - hc3 forward: `exact ⟨hF, h2, h3⟩` — anonymous ⟨hF, h2, h3⟩ = ⟨hF, ⟨h2, h3⟩⟩ ✓. - hc3 backward: goal `ρ ∈ circleZeros R ∧ ((¬q1 ∧ ¬q2) ∧ q3)`: = ⟨hF, ⟨⟨p1, h2⟩, h3⟩⟩ where p1 : ¬q1 ρ: `refine ⟨hF, ⟨⟨?_, h2⟩, h3⟩⟩` ✓ (what I wrote — refine ⟨⟨hF, ⟨?_, h2⟩⟩, h3⟩ — WRONG nesting again: mine had the outer pair as ⟨⟨hF, ...⟩, h3⟩ = ⟨hF, ...⟩ paired with h3 — the goal's structure is hF ∧ (pred): outer pair ⟨hF, pred-proof⟩ where pred-proof : (¬q1 ∧ ¬q2) ∧ q3 = ⟨⟨p1, h2⟩, h3⟩. So `refine ⟨hF, ⟨⟨?_, h2⟩, h3⟩⟩` ✓.) - hc4 forward: ⟨hF, ⟨-, h3⟩, h4⟩ → goal ⟨hF, h3, h4⟩ ✓ (I wrote ⟨⟨hF, h3⟩, h4⟩ — wrong). - hc4 backward: ⟨hF, ⟨⟨p1, p2⟩, h3⟩, h4⟩: `refine ⟨hF, ⟨⟨?_, ?_⟩, h3⟩, h4⟩` (mine had ⟨⟨hF, ⟨⟨?_, ?_⟩, h3⟩⟩, h4⟩ — wrong). - hc5 forward: ⟨hF, -, h4⟩ → ⟨hF, h4⟩ ✓ (I wrote ⟨hF, h4⟩? I wrote `exact ⟨hF, h4⟩`... let me check my code: hc5 forward: `rintro ⟨hF, -, h4⟩; exact ⟨hF, h4⟩` — hmm I wrote `exact ⟨hF, h4⟩`?? Looking at my text: `· rintro ⟨hF, -, h4⟩\n exact ⟨hF, h4⟩` — I actually wrote `exact ⟨hF, h4⟩`? No — I wrote `exact ⟨hF, h4⟩`... my text says `exact ⟨hF, h4⟩` — hmm no, I wrote: `· rintro ⟨hF, -, h4⟩\n exact ⟨hF, h4⟩` — checking the actual edit text: "· rintro ⟨hF, -, h4⟩\n exact ⟨hF, h4⟩" — the text was `exact ⟨hF, h4⟩`? In my edit: `· rintro ⟨hF, -, h4⟩\n exact ⟨hF, h4⟩` — I believe I wrote `exact ⟨hF, h4⟩`. Wait no — my text: `· rintro ⟨hF, -, h4⟩\n exact ⟨hF, h4⟩` hmm — scrolling: the hc5 block: `constructor\n · rintro ⟨hF, -, h4⟩\n exact ⟨hF, h4⟩` — the error at 2848/2849 is in hc5's backward: `refine ⟨⟨hF, ⟨⟨?_, ?_⟩, ?_⟩⟩, h4⟩` — wrong nesting: should be `refine ⟨hF, ⟨⟨?_, ?_⟩, ?_⟩, h4⟩`. And the "No goals to be solved" errors at 2822/2835/2849 — cascades from the broken exact/refine (the rintro had already closed/split, and the following bullet had no goal). Fixing the nestings resolves them.
The anonymous-constructor nestings are wrong (membership must be the first component of the outer pair). Fixing all three congruences.

Only the hRhi unused warning. hRhi (R ≤ 4k+3) is genuinely unused in THIS theorem (the series bound doesn't need the upper circle radius — it's needed for the LATER Fexpr assembly where Ĉ₀(4k+9/2) ≤ Ĉ₀(R+2)). Hmm — but the natural API for the next stage passes the full gap-circle data. Options: keep hRhi for API uniformity (with underscore prefix to silence), or drop it. The final consumer (5e-v-c) will apply this with R from exists_gapCircle_radius which supplies both bounds — dropping hRhi here means the caller just doesn't pass it. But keeping the signature uniform with not_isNontrivialZero_on_gapCircle (which also only needs hRlo)... For cleanliness, drop hRhi from seriesFun_norm_le_gapCircle. Actually wait — will 5e-v-c need Ĉ₀(4k+9/2) ≤ Ĉ₀(R+2)? That uses hRhi + C0hat_mono at the CALL site, not here. Drop it.
Clean except the unused `hRhi` — dropping it from the signature (callers supply it where needed).

Session 032 is complete. Summary for the user: - Chunk 3 (the main series circle bound) COMPLETE: `seriesFun_norm_le_gapCircle` proved — ‖seriesFun s‖ ≤ 2·lowZeroConst + 2900·A₀·Ĉ₀(4k+9/2)·(log R)² on the γ-gap circle (k ≥ 4000). - LiCircleBound.lean ~2867 lines, clean, zero warnings. - 6 commits (3a, 3b, 3c-i, 3c-ii, capstone, closure b829c21). - Axiom audit: 19 decls, 3 standard axioms only. - Next: 5e-v-c (logDeriv/elem assembly).

Session 033: ii′-5e-v-c — the logDeriv/elem assembly ⟹ ‖Fexpr s‖ ≤ C·(log R)³ on the γ-gap circles. Per protocol, I've already read STATE.md (it's in context from this session's work — the NEXT ACTION is fresh in context). Let me re-read the current STATE.md NEXT ACTION since I just rewrote it, plus check the design in journal-030 (already in context above). From STATE.md (just written): Session 033: **ii′-5e-v-c** — the logDeriv/elem assembly ⟹ ‖Fexpr s‖ ≤ C·(log R)³ on the γ-gap circles (LiCircleBound.lean §10). Design (journal-030): 1. **logDeriv ζ on the circle**, three arc families: - strip arcs (re s ∈ [−5/2, 7/2], |im s| ≥ 10): the 5c/5d capstones `logDeriv_riemannZeta_sub_nearZeros_le` (100000·(log|t|)²) and `..._left` (200000·(log|t|)²) + the near sum Σ_{|γ−t|<1} m/|s−ρ| ≤ 32Ĉ₀·(count): the γ-gap gives |t−γ| ≥ 1/(32Ĉ₀) on these arcs (reuse shell_crit's hsep argument); the count ≤ 2·A₀·log(|t|+4) (two Ncount windows). - right near-axis (re s ≥ √(R²−100) ≥ 2): the Dirichlet bound `norm_logDeriv_zeta_le_dirichlet` (‖ζ′/ζ‖ ≤ dirichletC2). - left near-axis (re s ≤ −√(R²−100)): 5d's `logDeriv_zeta_fe` pointwise + Dirichlet at 1−s + the ΓR brackets via 5e-ii (A)/(B) + `logDeriv_Gammaℝ_eq` (G, im ≠ 0; the REAL point s = −R by closure/continuity). 2. **elems**: 1/s, 1/(s−1) = O(1/R); ψ(s/2)/2 = O(log R): right arc via 5e-ii (B) `norm_digamma_le_of_two_le_re`; strip arcs via 5d's `norm_digamma_sub_log_le_of_two_le_abs_im` (|im(s/2)| ≥ 5) + ‖log w‖ ≤ log‖w‖ + π (LiReflect:414); left arc via 5e-ii (A) `norm_digamma_le_of_dist_nat` with dist(s/2, −ℕ) ≥ 1/8 (from dist(R/2, ℤ) ≥ 1/4 — the hgapInt hypothesis from exists_gapCircle_radius, NOT yet a theorem argument: add it). 3. Assemble: ‖Fexpr s‖ ≤ ‖logDeriv ζ‖ + ‖seriesFun‖ + ‖1/s‖ + ‖1/(s−1)‖ + ‖(log π)/2‖ + ‖ψ(s/2)/2‖ ≤ C·(log R)³ (Ĉ₀(4k+9/2) ≤ Ĉ₀(R+2) via C0hat_mono + R ≤ 4k+3). I need to look at the exact signatures of: - `logDeriv_riemannZeta_sub_nearZeros_le` (5c, LiDisc.lean) - `logDeriv_riemannZeta_sub_nearZeros_le_left` (5d, LiReflect.lean) - `nearZeros` definition - `logDeriv_zeta_fe` (5d) - `norm_digamma_sub_log_le_of_two_le_abs_im` (5d) - `norm_digamma_le_of_two_le_re` (5e-ii, LiDigammaLeft) - `norm_digamma_le_of_dist_nat` (5e-ii) - `logDeriv_Gammaℝ_eq` (5e-ii) - `Complex.digamma` definition/API - Fexpr definition (5e-iv): `Fexpr s := logDeriv ζ s − seriesFun s + 1/s + 1/(s−1) − (log π)/2 + ψ(s/2)/2` where ψ = Complex.digamma. The work plan for 5e-v-c: **Part 1: logDeriv ζ on the circle.** For s with ‖s‖ = R (gap circle, k ≥ 4000): - Case A: |im s| ≥ 10 AND re s ∈ [−5/2, 7/2]: - if re s ≥ 1/2: 5c capstone: ‖logDeriv ζ s − Σ_{ρ ∈ nearZeros t} m/(s−ρ)‖ ≤ 100000·(log|t|)². - if re s ≤ 1/2: 5d capstone: ‖logDeriv ζ s − Σ_{ρ ∈ nearZeros (−t)?}...‖ ≤ 200000·(log|t|)². Wait — the left version has nearZeros too (nearZeros t or nearZeros (−t)?). Let me check the exact statements. - The near sum: Σ_{ρ ∈ nearZeros t} m·‖1/(s−ρ)‖ ≤ (count)·32Ĉ₀ — because for ρ ∈ nearZeros t (|γ−t| < 1, nontrivial zeros): ‖s−ρ‖ ≥ 1/(32Ĉ₀) — the shell_crit arc analysis applies? In shell_crit, hsep was for ρ in the critical SHELL (‖ρ‖ ∈ (R−2, R+2)). For the near sum, ρ ∈ nearZeros t: |γ−t| < 1 ⟹ ‖ρ‖ ≈ |t| ≈ R — need ‖ρ‖ ∈ (R−2, R+2) to reuse hsep: |‖ρ‖−|t|| ≤ |re ρ| ≤ 1 hmm: ‖ρ‖ ≤ |re|+|im| ≤ 1+|γ| ≤ 1+|t|+1 = R+2·... ‖ρ‖ ≥ |γ| ≥ |t|−1 hmm |t| ≤ R: ‖ρ‖ ∈ [|t|−1, |t|+2] — and |t| ∈ [10, R]: ‖ρ‖ ∈ [9, R+2]: NOT necessarily > R−2 (|t| could be < R−1). Hmm — but for those ρ with ‖ρ‖ ≤ R−2: ‖s−ρ‖ ≥ R−‖ρ‖ ≥ 2·... wait no: ‖s−ρ‖ ≥ |‖s‖−‖ρ‖| = R−‖ρ‖ ≥ 2 if ‖ρ‖ ≤ R−2. So: - ρ with ‖ρ‖ > R−2: then ‖ρ‖ ∈ (R−2, R+2): ρ in the critical shell: hsep applies IF ρ ∈ FS (the crit filter — also needs ρ ∈ circleZeros R: ‖ρ‖ < 2R+1 ✓ since ‖ρ‖ ≤ R+2). hsep gives ‖s−ρ‖ ≥ 1/(32Ĉ₀). - ρ with ‖ρ‖ ≤ R−2: ‖s−ρ‖ ≥ 2 ≥ 1/(32Ĉ₀) ✓ (1/(32Ĉ₀) ≤ 1/64 ≤ 2). So uniformly ‖s−ρ‖ ≥ 1/(32Ĉ₀) for ALL ρ ∈ nearZeros t on these arcs. - near sum ≤ 32Ĉ₀·Σ_{nearZeros t} m: the mult-count of nearZeros t: nearZeros t = zeros with |γ−t| < 1 (def? need to check — in LiDisc.lean: nearZeros t := {ρ | IsNontrivialZero ρ ∧ |γ−t| < 1} as a Finset?). Count: Ncount(t−1, t+1] + Ncount(−t−1, −t+1] ≤ 2·A₀·3·log(3(|t|+1)+5)-ish — via the interval count or directly Ncount_le_of_interval_gen: Ncount(t−1, t+1] ≤ A₀·3·log(3·max|t−1||t+1|+5). Or use the existing nearZeros cardinality bound — maybe 5c already has one? Let me check LiDisc for a nearZeros-count lemma. - So strip arcs: ‖logDeriv ζ s‖ ≤ 200000·(log|t|)² + 32Ĉ₀·(near count) ≤ 200000·(log R)² + 32Ĉ₀·2·A₀·3·log(3(R+1)+5) = O((log R)² + Ĉ₀A₀ log R). - Case B: re s ≥ √(R²−100) (right near-axis, |im s| ≤ 10): re s ≥ √(R²−100) ≥ 2 for R ≥ ~11: Dirichlet bound: ‖logDeriv ζ s‖ ≤ dirichletC2. CONSTANT. - Case C: re s ≤ −√(R²−100) (left near-axis, |im s| ≤ 10): use logDeriv_zeta_fe: logDeriv ζ s = −logDeriv ζ(1−s) − [logDeriv ΓR s + logDeriv ΓR(1−s)]: re(1−s) = 1−re s ≥ 1+√(R²−100) ≥ 2: Dirichlet: ‖logDeriv ζ(1−s)‖ ≤ dirichletC2. The ΓR brackets: logDeriv ΓR s + logDeriv ΓR(1−s): via 5e-ii (G): logDeriv ΓR w = −(log π)/2 + ½ψ(w/2) for im w ≠ 0. im s ≠ 0 here (|im s|... wait in case C, |im s| ≤ 10 — could im s = 0? The real point s = −R: re = −R ≤ −√(R²−100) ✓ — so the real point IS in case C! That's why the design says "the REAL point s = −R via the closure/continuity extension". Hmm — this complicates: for im s = 0 (s = −R exactly): logDeriv_zeta_fe needs "good points" (s not a pole/zero/trivial?). ζ(−R) ≠ 0? −R: trivial zeros are at −2n: dist(R/2, ℤ) ≥ 1/4 ⟹ R/2 ∉ ℤ ⟹ R ∉ 2ℤ... wait dist(R/2,ℤ) ≥ 1/4 means R/2 is not an integer, so R is not an even integer — but −R could still be... −2n = −R ⟺ R = 2n even integer — excluded ✓. But ζ(−R) for −R odd-integer or non-integer: nonzero ✓ (only trivial zeros are −2n). But is s = −R an integer at all? R ∈ [4k+5/2, 4k+3]: R = 4k+3 possible (integer, odd) — then −R = −(4k+3) odd negative integer: ζ(−odd) = −B_{n+1}/(n+1) ≠ 0 ✓. And logDeriv_zeta_fe's hypotheses — need to check what "good points" means (probably ζ s ≠ 0, s ≠ 0, s ≠ 1, not trivial zero — exactly the Fexpr good-point conditions). For s = −R: ζ(−R) ≠ 0 ⟸ zero classification (zeros = nontrivial ∪ {0} ∪ {−2n}): −R ∉ those (re < 0, ≠ −2n, ≠ 0) ⟹ ζ(−R) ≠ 0 via zeta_zero_classification ✓. So for ALL points of case C (including s = −R), logDeriv_zeta_fe applies IF its hypotheses are the good-point ones. And logDeriv_Gammaℝ_eq needs im ≠ 0 — at s = −R (im = 0) that fails! The design: "the REAL point s = −R via the closure/continuity extension — the bound set is closed and the im ≠ 0 arc points are dense". So: prove the BOUND for im ≠ 0 points of case C, then extend to s = −R by continuity of logDeriv ΓR (it's continuous at −R since ΓR(−R) ≠ 0 — hmm ΓR(s) = π^{−s/2}Γ(s/2): at s = −R: Γ(−R/2): −R/2: dist(R/2,ℤ) ≥ 1/4 ⟹ −R/2 ∉ ℤ... wait −R/2 near negative integers/half: Γ has poles at 0,−1,−2,...: −R/2 ∈ nonpositive integers iff R/2 ∈ ℕ ⟺ R/2 ∈ {0,1,2,...}: dist(R/2,ℤ) ≥ 1/4 ⟹ R/2 ∉ ℤ ⟹ Γ(−R/2) finite, ΓR(−R) ≠ 0 ✓ so logDeriv ΓR continuous at −R ✓). The continuity extension: the bound ‖g(s)‖ ≤ C on the dense subset {im ≠ 0} ∩ case-C-arc, g continuous at −R ⟹ ‖g(−R)‖ ≤ C (norm continuity + closure: ‖g(−R)‖ = lim ‖g(s_n)‖ ≤ C). In Lean: has a clean path? (Continuous.norm + Tendsto.le_of_tendsto... or IsClosed.mem_of_tendsto). Since the arc is one point, simplest: take a sequence s_n → −R along the arc (s_n = −R + i/n·... wait the arc is |s| = R: points near −R on the circle: s(θ) = R·e^{i(π−1/n)}-ish. Simpler: s_n := ⟨−√(R²−1/n²), 1/n⟩ hmm — or R·cos(π−1/n) + i·R·sin(π−1/n)·... Any sequence on the circle with im ≠ 0 converging to −R: s_n := (R·exp(I·(π − 1/(n+1)))): ‖s_n‖ = R ✓ im = R·sin(π−1/(n+1)) = R·sin(1/(n+1)) > 0 ✓ → 0, re → R·cos π = −R ✓. Tendsto s_n (−R) via the continuous exp. Then the bound at −R by continuity. Hmm — this is doable but adds machinery. ALTERNATIVE cleaner: bound the digamma bracket DIRECTLY at s = −R via 5e-ii (A) `norm_digamma_le_of_dist_nat` (the near-axis bound for re ≤ 2, dist(w,−ℕ) ≥ c — covers REAL points!). And for logDeriv ΓR at s = −R: use the recurrence instead of (G)? (G) needs im ≠ 0. Hmm — what is logDeriv ΓR at a real point? = −(log π)/2 + ½ψ(s/2) — the identity (G) is stated for im ≠ 0. For the real point, prove the same identity by continuity, OR use the fact that logDeriv ΓR = −(logπ)/2 + ½ψ(s/2) holds EVERYWHERE off the poles (the identity theorem: both sides analytic on ℂ \ {poles}, agree on im ≠ 0 dense ⟹ agree everywhere in the domain). Mathlib identity principle: AnalyticOnNhd.eq_of_frequently_eq... That's the analytic-continuation route — heavier. OR: bound the BRACKET ‖logDeriv ΓR s + logDeriv ΓR(1−s)‖ directly with the m-fold shift machinery from 5d/5e-ii at the real point... Simplest robust: the continuity-of-the-BOUND route (sequence + tendsto): it only needs continuity of the bracket (analytic at −R) and the bound on the dense set. ~30-40 lines. I'll do that. Actually wait — even simpler: prove the case-C bound for ALL s in case C with im s ≠ 0, and handle s = −R SEPARATELY by the same digamma machinery: at s = −R: logDeriv ΓR(−R) = −(logπ)/2 + ½ψ(−R/2) — again the identity needed. Hmm no. OK let me now think about what the digamma bracket bound IS. ψ(s/2)/2 + ψ((1−s)/2)/2 — wait no: the FE bracket is logDeriv ΓR s + logDeriv ΓR(1−s) = −log π + ½[ψ(s/2) + ψ((1−s)/2)] (via (G) for im ≠ 0). Bound: - ψ(s/2): case C: re(s/2) ≤ −√(R²−100)/2 ≤ ~−R/2: far left: 5e-ii (A): dist(s/2, −ℕ) ≥ 1/8 (from dist(R/2,ℤ) ≥ 1/4 and |re(s/2) + R/2| ≤ |im s|/(2R)-ish: s/2 = (re s + i·im s)/2: re(s/2) = (re s)/2 ∈ [−R/2, −√(R²−100)/2]: so s/2 has re ∈ [−R/2, −√(R²−100)/2] and |im(s/2)| ≤ 5: the distance from s/2 to −ℕ: |s/2 − (−n)| for n ∈ ℕ: closest −n to re(s/2) = re s/2: re s/2 ∈ [−R/2, −√(R²−100)/2]: |re s/2 − (−n)| ≥ dist(re s/2, −ℕ) hmm and R/2 has dist(R/2, ℤ) ≥ 1/4: re s/2 = (re s)/2 with re s ∈ [−R, −√(R²−100)]: re s/2 ∈ [−R/2, −√(R²−100)/2]: dist(re s/2, −ℕ): let m := the nearest integer to re s/2... hmm −ℕ = {0,−1,−2,...}: re s/2 ∈ [−R/2, ...]: distance from re s/2 to −ℕ = distance to the nearest nonpositive integer — the design (journal-030) says: "left arc via 5e-ii (A) with dist(s/2, −ℕ) ≥ 1/8 (from dist(R/2, ℤ) ≥ 1/4 and |re s/2| ∈ [√(R²−100)/2, R/2] ⊆ [R/2 − 26/R, R/2], R ≥ 208)": so re s/2 ∈ [−R/2, −R/2+26/R]: the point −R/2 has dist(R/2, ℤ) ≥ 1/4 ⟹ dist(−R/2, −ℕ·... dist(−R/2, ℤ) = dist(R/2,ℤ) ≥ 1/4: and re s/2 ∈ [−R/2, −R/2+26/R]: |re s/2 − (−R/2)| ≤ 26/R ≤ 1/8 (R ≥ 208): so dist(re s/2, −ℕ) ≥ 1/4 − 1/8 = 1/8 ✓ (triangle: dist to nearest integer ≥ dist(−R/2,ℤ) − |re s/2−(−R/2)| ≥ 1/4 − 1/8). And |s/2 − (−n)| ≥ |re(s/2 −(−n))| = |re s/2 + n| ≥ dist(re s/2, −ℕ) ≥ 1/8 ✓. So dist(s/2, −ℕ) ≥ 1/8 (with the set-distance definition from 5e-ii (A) — need to check the exact form: `norm_digamma_le_of_dist_nat` — what does it take? dist(w, −ℕ) ≥ c probably as ∀ n : ℕ, c ≤ ‖w + n‖ or similar. Check the signature.) - ψ((1−s)/2): re((1−s)/2) = (1−re s)/2 ≥ (1+√(R²−100))/2 ≥ ~R/2 ≥ 2: 5e-ii (B): ‖ψ((1−s)/2)‖ ≤ 20·log(2+‖(1−s)/2‖) ✓ (B needs re ≥ 2 and |im| ≤ 5: |im((1−s)/2)| = |im s|/2 ≤ 5 ✓). - So bracket ≤ log π + ½[((46+2/(1/8)) + 23·log(2+‖s/2‖)) + 20·log(2+‖(1−s)/2‖)] = O(log R) — via 5e-ii (A): ‖ψ(w)‖ ≤ (46 + 2/c) + 23·log(2+‖w‖) with c = 1/8: 46+16 = 62. So ‖ψ(s/2)‖ ≤ 62 + 23·log(2+R/2) = O(log R). - Thus case C: ‖logDeriv ζ s‖ ≤ dirichletC2 + log π + ½(62 + 23·log(2+R/2)) + ½·20·log(2+(R+1)/2) = O(log R). **Part 2: the elementary terms.** - ‖1/s‖ = 1/R ≤ 1. - ‖1/(s−1)‖ = 1/‖s−1‖ ≤ 1/(R−1) ≤ 1 (s ≠ 1 ✓ since ‖s‖ = R > 1). - ‖(log π)/2‖: constant ≤ (log π)/2 — need log π bounded: log π ≤ 2 (π ≤ e² ⟸ π ≤ 4·... π < 3.15 ≤ e² ✓ via Real.pi_lt_315 or similar). - ψ(s/2)/2: - right near-axis (case B: re s ≥ √(R²−100)): re(s/2) ≥ √(R²−100)/2 ≥ 2 (R ≥ 11): |im(s/2)| ≤ 5: 5e-ii (B): ‖ψ(s/2)‖ ≤ 20·log(2+‖s/2‖) ≤ 20·log(2+R/2) = O(log R). - strip arcs (re ∈ [−5/2, 7/2], |im| ≥ 10): |im(s/2)| ≥ 5: 5d's `norm_digamma_sub_log_le_of_two_le_abs_im`: ‖ψ(w) − log w‖ ≤ 3 for |im w| ≥ 2: with w = s/2: ‖ψ(s/2)‖ ≤ ‖log(s/2)‖ + 3 ≤ (log‖s/2‖ + π) + 3 (‖log w‖ ≤ log‖w‖ + π for complex log — LiReflect:414 per journal-030: there's a lemma `norm_log_le` in LiReflect). log‖s/2‖ = log(R/2) = O(log R). - left near-axis (case C): same as the case-C digamma above: ‖ψ(s/2)‖ ≤ 62 + 23·log(2+R/2) via 5e-ii (A) with c = 1/8. **Part 3: assembly.** ‖Fexpr s‖ ≤ ‖logDeriv ζ s‖ + ‖seriesFun s‖ + ‖1/s‖ + ‖1/(s−1)‖ + ‖log π /2‖ + ‖ψ(s/2)/2‖. The Fexpr definition: `Fexpr s := logDeriv ζ s − seriesFun s + 1/s + 1/(s−1) − (log π)/2 + ψ(s/2)/2` — check exact form in LiFEntire.lean. Then norm ≤ sum of norms (norm_add_le / norm_sub_le chain). Each piece: - ‖logDeriv ζ s‖: case-dependent: strip: 200000·(log R)² + 96·Ĉ₀·A₀·(2L)-ish; right: dirichletC2; left: dirichletC2 + log π + 62/2+... Let me just compute a uniform bound: ‖logDeriv ζ s‖ ≤ 200000·(log R)² + 200·Ĉ₀·A₀·log R + dirichletC2 + log π + 62 + 43·log R·... — uniform across cases. Then total: ‖Fexpr s‖ ≤ [200000·L² + 200Ĉ₀A₀L + dirichletC2 + log π + 62 + 43L] + [2·lowZeroConst + 2900A₀Ĉ₀L²] + [1] + [1] + [log π/2] + [½(62+23·log(2+R/2)) or ½(20·log(2+R/2)+3+π)]. Everything ≤ C·A₀·Ĉ₀·L² for a suitable C with the lowZeroConst and dirichletC2 as additive symbolic constants. For the squeeze (5e-v-d), the bound just needs to be o(R): (log R)²·Ĉ₀ ~ (log R)³·loglog — the squeeze works with any polylog. Form: ‖Fexpr s‖ ≤ 2·lowZeroConst + dirichletC2 + C·A₀·Ĉ₀·(log R)² — hmm — Ĉ₀ here is Ĉ₀(4k+9/2); convert to Ĉ₀(R+2) via C0hat_mono (R ≤ 4k+3 ⟹ 4k+9/2 ≤ R+2 hmm 4k+4.5 vs R+2 ≥ 4k+4.5 ⟺ R ≥ 4k+2.5 ✓ so Ĉ₀(4k+9/2) ≤ Ĉ₀(R+2)?? mono needs a ≤ b: 4k+9/2 ≤ R+2 ⟺ 4k+5/2 ≤ R ✓ YES). So bound in terms of Ĉ₀(R+2) — cleaner for the squeeze (R-dependent only). Let me design the final form: ‖Fexpr s‖ ≤ 2·lowZeroConst + dirichletC2 + 400000·A0count·C0hat (R+2) · (Real.log R)^2 (picking a round C = 400000 that absorbs everything: the strip 200000·L² + 96Ĉ₀A₀·2L ≤ 200000L² + 192Ĉ₀A₀L² (L ≥ 1) ≤ (200000 + 192·... hmm — 200000·L² alone needs to fit inside 400000·A₀·Ĉ₀·L²: A₀ ≥ 1, Ĉ₀ ≥ 2: 400000·A₀·Ĉ₀·L² ≥ 800000·L² ≥ 200000·L² ✓ huge slack. The series 2900·A₀·Ĉ₀·L² ✓ fits. The rest are lower-order or symbolic constants absorbed into the additive 2·lowZeroConst + dirichletC2 term... but some are log-terms without Ĉ₀/A₀: 62, log π, 43L, 62+23·log(2+R/2): these need absorption into A₀·Ĉ₀·L² as well: 62+23·log(2+R/2) ≤ 62+23·(L+... log(2+R/2) ≤ log(2R) hmm for R ≥ 4: 2+R/2 ≤ R (R ≥ 4): ≤ log R = L: so 62+23L ≤ (62/2+23)·Ĉ₀·L²·... Ĉ₀ ≥ 2, L ≥ 9: 62 ≤ 62·Ĉ₀·L²/(2·81)·... simplest: 62 ≤ 62·A₀·Ĉ₀·L²·(1/(1·2·81))·... let me just make the constant bigger and absorb: each of 62, 43L, log π ≤ 100·L² ≤ 50·Ĉ₀·A₀·L² (A₀ ≥ 1, Ĉ₀ ≥ 2, L² ≥ 1). And 1+1 (the 1/s, 1/(s−1)). And dirichletC2 + 2·lowZeroConst stay symbolic additive. Final form: ‖Fexpr s‖ ≤ 2·lowZeroConst + dirichletC2 + 400000·A0count·C0hat (R+2)·(Real.log R)^2 — need to verify every piece ≤ its share. Let me budget: total allowance 400000·A₀Ĉ₀L²: - series: 2900·A₀Ĉ₀L² (direct). - strip logDeriv: 200000·L² + 192·Ĉ₀A₀·L·... let me recompute the near sum: 32Ĉ₀·(count): count ≤ 2·A₀·3·log(3(|t|+1)+5)·... hmm the near-window: nearZeros t — what's its def? Probably {ρ nontrivial ∧ |ρ.im − t| < 1} or zerosIn(t−1, t+1]. Count via Ncount: Ncount(t−1, t+1] + Ncount(−t−1, −t+1]: each ≤ A₀·(2+1)·log(3·max+5) = 3A₀·log(3(|t|+1)+5): total 6A₀·log(3(|t|+1)+5) ≤ 6A₀·2L = 12A₀L (3(|t|+1)+5 ≤ 3(R+1)+5 = 3R+8 ≤ 4R: log(4R) ≤ 2L ✓). So near sum ≤ 32Ĉ₀·12A₀L = 384Ĉ₀A₀L ≤ 384Ĉ₀A₀L². Strip total: 200000·L² + 384·Ĉ₀A₀L² ≤ 200000·A₀Ĉ₀L²/2·... 200000·L² ≤ 100000·A₀Ĉ₀L² (A₀Ĉ₀ ≥ 2): so strip ≤ 100384·A₀Ĉ₀L². - left: dirichletC2 (symbolic, goes to the additive) + log π + 62/2... wait: left logDeriv ≤ dirichletC2 + [log π + ½(62 + 23·log(2+‖s/2‖)) + ½·20·log(2+‖(1−s)/2‖)]: the bracket ≤ log π + 31 + 11.5·log(2+R/2) + 10·log(2+(R+1)/2): log(2+(R+1)/2) ≤ log(2+R/2+1/2) hmm ≤ log(R) for R ≥ 5 (2+(R+1)/2 = (R+5)/2 ≤ R ⟺ 5 ≤ R ✓): so ≤ log π + 31 + 21.5·L. The digamma piece here is SEPARATE from the elem ψ(s/2)/2 — careful not to double count: case C's elem ψ(s/2)/2 = the SAME ψ(s/2) bound (62+23L)/2. And the FE bracket has its own ψ(s/2) + ψ((1−s)/2). So in case C: logDeriv uses ψ(s/2) and ψ((1−s)/2); the elem uses ψ(s/2) again. Fine — just count each occurrence. - So universal assembly (bounding each piece by the max over cases): ‖logDeriv ζ‖ ≤ max(strip, right, left) ≤ 100384·A₀Ĉ₀L² + dirichletC2 + (log π + 31 + 21.5·L) — hmm the left's bracket. Uniform: ‖logDeriv ζ‖ ≤ 100384·A₀Ĉ₀L² + dirichletC2 + log π + 31 + 22·L (the non-Ĉ₀ part only from the left bracket; absorb: log π + 31 + 22L ≤ (2+31+22)·Ĉ₀A₀L²/2... log π ≤ 2, so ≤ 55·L·... ≤ 55·A₀Ĉ₀L² (L ≥ 1, A₀Ĉ₀ ≥ 2 ⟹ A₀Ĉ₀L² ≥ 2L² ≥ 2·... 55·L ≤ 55·A₀Ĉ₀L² ⟸ A₀Ĉ₀L ≥ 1 ✓). So ‖logDeriv ζ‖ ≤ dirichletC2 + 100439·A₀Ĉ₀L². Hmm wait — but the LEFT case's logDeriv ≤ dirichletC2 + bracket — no 200000·L² there; the strip's 200000·L² + near — no bracket. The uniform bound takes the max: ≤ 200000·L² + 384Ĉ₀A₀L² + dirichletC2 + log π + 31 + 22L ≤ dirichletC2 + 100000·A₀Ĉ₀L²·... 200000·L² = 100000·2·L² ≤ 100000·A₀Ĉ₀L²: total ≤ dirichletC2 + (100000 + 384 + 55)·A₀Ĉ₀L² = dirichletC2 + 100439·A₀Ĉ₀L² ✓. - ψ(s/2)/2 ≤ max(right: 10·log(2+R/2) ≤ 10L, strip: (L + π + 3)/2 ≤ (2L+3+2)/2 hmm: ‖log(s/2)‖ + 3 ≤ log(R/2) + π + 3 = L − log2 + π + 3 ≤ L + 2 + 3 = L+5 (log π ≤ 2 hmm π the number: ‖log w‖ ≤ log‖w‖ + π where π ≈ 3.14: so ≤ log(R/2) + π + 3 ≤ L + 3.15 + 3 = L + 6.15: /2: ≤ (L+7)/2), left: (62 + 23L)/2): uniform ≤ 31 + 12·L ≤ (31+12)·A₀Ĉ₀L²/2·... 31+12L ≤ 43L² ≤ 22·A₀Ĉ₀L² (A₀Ĉ₀ ≥ 2) ✓.

A₀Ĉ₀L² ≥ 162: 31 ≤ 31/162·A₀Ĉ₀L² ≤ 0.2·A₀Ĉ₀L²: so 31+12L ≤ 12·A₀Ĉ₀L² + 0.2·A₀Ĉ₀L² ≤ 13·A₀Ĉ₀L² ✓). - 1/s + 1/(s−1) ≤ 2 ≤ 2·A₀Ĉ₀L²/324·... tiny: 2 ≤ A₀Ĉ₀L² (A₀Ĉ₀L² ≥ 162 ≥ 2 ✓). - ‖(log π)/2‖ ≤ 1 ≤ A₀Ĉ₀L². - series: 2900·A₀Ĉ₀L² + 2·lowZeroConst. TOTAL: ‖Fexpr‖ ≤ [dirichletC2 + 100439] + [13] + [1] + [1] + [2900] A₀Ĉ₀L² + 2·lowZeroConst = 2·lowZeroConst + dirichletC2 + 103355·A₀Ĉ₀L² ≤ 2·lowZeroConst + dirichletC2 + 400000·A₀Ĉ₀L² ✓ plenty of room. Hmm wait — one more check on the strip-arc split: the 5c capstone is for re s ∈ [1/2, 7/2] and the 5d LEFT capstone for re s ∈ [−5/2, 1/2]. The strip arcs of the circle: |im s| ≥ 10 and re s ∈ [−√(R²−100), √(R²−100)] — re s can be up to √(R²−100) ≈ R huge! The 5c/5d capstones only cover re ∈ [−5/2, 7/2]! For re s > 7/2 (with |im s| ≥ 10): that's covered by... hmm — re s ∈ (7/2, √(R²−100)) with |im s| ≥ 10: which bound? re s > 7/2 ≥ 2: DIRICHLET! (re ≥ 2 ✓). Similarly re s < −5/2 with |im s| ≥ 10: the LEFT-plane: 5d's FE route (like case C but with |im| ≥ 10 instead of ≤ 10): the digamma bounds differ: ψ(s/2) with |im(s/2)| ≥ 5: use 5d's norm_digamma_sub_log (like the strip elem) instead of 5e-ii (A)! So actually the case split is better organized as: **By re s**: (i) re s ≥ 2: Dirichlet (covers right near-axis AND right-strip re ∈ [2, √(R²−100)]). (ii) re s ∈ [−5/2, 2]: hmm — 5c needs re ∈ [1/2, 7/2]; 5d-left needs re ∈ [−5/2, 1/2]: union [−5/2, 7/2] hmm but the capstones ALSO need |t| ≥ 10. For re ∈ [−5/2, 2] with |im| < 10: those are near-axis LEFT-ish points (re ∈ [−5/2, 2] ⊂ [−√(R²−100), √(R²−100)] for R big... wait |im| < 10 ⟹ |re| ≥ √(R²−100) ≫ 2: contradiction: |im| < 10 ⟹ re² ≥ R²−100 ⟹ |re| ≥ √(R²−100) ≥ ~R: so re ∈ [−5/2, 2] with |im| < 10 is IMPOSSIBLE for R ≥ 11 (|re| ≥ √(R²−100) > 2). GOOD: so the region re ∈ [−5/2, 2] only occurs with |im| ≥ 10 ✓ capstones apply (5c for [1/2, 2], 5d-left for [−5/2, 1/2] — union covers [−5/2, 2] ✓ overlap at 1/2 ✓). (iii) re s < −5/2: the FE route: logDeriv ζ s = −logDeriv ζ(1−s) − bracket: re(1−s) ≥ 1+5/2 = 7/2 ≥ 2: Dirichlet at 1−s ✓. The digamma bracket: ψ(s/2): re(s/2) < −5/4: two sub-cases: |im(s/2)| ≥ 5 (|im s| ≥ 10): 5d's norm_digamma_sub_log (‖ψ−log‖ ≤ 3 ⟹ ‖ψ‖ ≤ ‖log‖+3 ≤ log‖s/2‖+π+3); |im(s/2)| < 5 (|im s| < 10 — the left near-axis): 5e-ii (A) with dist ≥ 1/8 ✓. And ψ((1−s)/2): re((1−s)/2) = (1−re s)/2 ≥ (1+5/2)/2 = 7/4 ≥ ... hmm (B) needs re ≥ 2: (1−re s)/2 with re s < −5/2: (1−re s)/2 > (1+5/2)/2 = 1.75 — NOT ≥ 2 always! For re s ∈ (−5, −5/2): (1−re s)/2 ∈ (1.75, 3): below 2. Hmm — 5e-ii (B) needs re w ≥ 2. For re w ∈ [1.75, 2): use... the digamma recurrence ψ(w) = ψ(w+1) − 1/w: ψ((1−s)/2) = ψ((1−s)/2+1) − 1/((1−s)/2): re((1−s)/2+1) = (3−re s)/2 ≥ 2.75 ≥ 2 ✓ (B) applies with the shift: ‖ψ(w)‖ ≤ ‖ψ(w+1)‖ + 1/‖w‖ ≤ 20·log(2+‖w+1‖) + 1/1.75-ish. Or just use (A) for the whole ψ((1−s)/2)?? (A) is for re ≤ 2 with dist(w,−ℕ) ≥ c: re((1−s)/2) ≥ 1.75 — could apply (A) with c = 1: dist((1−s)/2, −ℕ) ≥ 1.75 ≥ 1 ✓ (re ≥ 1.75 ⟹ distance to −ℕ ≥ 1.75). Hmm (A) gives ‖ψ‖ ≤ (46+2/c) + 23·log(2+‖w‖) = 48 + 23·log(...). Uniform: for ψ((1−s)/2) use (A) with c = 1: ≤ 48 + 23·log(2+(R+1)/2) = O(log R) ✓ no recurrence needed. But wait — (A)'s hypothesis: re w ≤ 2: re((1−s)/2) ≥ 1.75 could EXCEED 2 (re s < −3: (1−s)/2's re > 2). Then use (B) (re ≥ 2). Split: re((1−s)/2) ≤ 2 vs ≥ 2: (A) with c = 1 hmm — (A) needs re ≤ 2 AND dist ≥ c: for re ≤ 2: dist ≥ re ≥ 1.75 ≥ 1 ✓; for re ≥ 2: (B) with |im| ≤ 5: |im((1−s)/2)| = |im s|/2: in case (iii), |im s| can be ≥ 10 (the left-strip)! Then |im((1−s)/2)| ≥ 5: (B) needs |im| ≤ 5?? Let me check 5e-ii (B)'s signature: `norm_digamma_le_of_two_le_re` — from STATE: "(B): ‖ψ‖ ≤ 20 log(2+‖w‖), re ≥ 2" — the journal-030 design says "right arc via 5e-ii (B) (re ≥ 2, |im| ≤ 5)". So (B) has an |im| ≤ 5 hypothesis?! For |im((1−s)/2)| ≥ 5: use 5d's norm_digamma_sub_log (|im| ≥ 2): ‖ψ−log‖ ≤ 3: ‖ψ‖ ≤ ‖log w‖+3. So ψ((1−s)/2): |im| ≥ 5: sub-log bound; |im| < 5: re ≥ 2: (B); re ∈ [1.75, 2]: (A) c = 1. Ugh — three sub-cases but each simple. OR unify: for ANY w with re w ≥ 1.75: ‖ψ(w)‖ ≤ 48 + 23·log(2+‖w‖)?? — hmm (A) requires re ≤ 2. For re > 2 with |im| ≥ 5 the sub-log bound ≤ log‖w‖ + π + 3 ≤ 48+23·log(2+‖w‖) ✓ (log‖w‖ ≤ log(2+‖w‖)·... log(2+‖w‖) ≥ log 2 > 0: π+3 ≤ 7 ≤ 48 ✓ and log‖w‖ ≤ 23·log(2+‖w‖) ✓). For re > 2 with |im| < 5: (B): 20·log(2+‖w‖) ≤ 48+23·log(2+‖w‖) ✓. For re ∈ [1.75, 2]: (A) c = 1: (46+2) + 23·log(2+‖w‖) = 48+23·log(2+‖w‖) ✓ EXACT. So uniform: re w ≥ 1.75 ⟹ ‖ψ(w)‖ ≤ 48 + 23·log(2+‖w‖). A small lemma `digamma_right_le` combining the three. ✓ Similarly for ψ(s/2) (re(s/2) < −5/4): sub-cases on |im(s/2)|: ≥ 5: sub-log: ‖ψ‖ ≤ log‖s/2‖ + π + 3; < 5: (A) c = 1/8: 62 + 23·log(2+‖s/2‖). Uniform: ‖ψ(s/2)‖ ≤ 62 + 23·log(2+‖s/2‖) (sub-log ≤ log‖s/2‖+π+3 ≤ 23·log(2+‖s/2‖) + 62 ✓ since π+3 ≤ 7 ≤ 62 and log‖s/2‖ ≤ 23·log(2+‖s/2‖) ✓ — wait log‖s/2‖ vs 23·log(2+‖s/2‖): log(2+x) ≥ log x hmm x = ‖s/2‖: log(2+x) ≥ log x ✓ so log x ≤ log(2+x) ≤ 23·log(2+x) ✓.) So: case (iii) bracket: ‖logDeriv ΓR s + logDeriv ΓR(1−s)‖ ≤ log π + ½(‖ψ(s/2)‖ + ‖ψ((1−s)/2)‖) ≤ log π + ½(62 + 23·log(2+‖s/2‖)) + ½(48 + 23·log(2+‖(1−s)/2‖)) ≤ 2 + 55 + 12·log(2+R/2) + 12·log(2+(R+1)/2)·... ≤ 57 + 24·L-ish. And case (ii) the near-sum — for re s ∈ [−5/2, 2] (with |im s| ≥ 10 automatic): the capstones have the near-sum Σ_{ρ ∈ nearZeros t} (zeroMult ρ)/(s−ρ) — need the EXACT statements of the 5c/5d capstones. Let me look at LiDisc.lean's capstone and LiReflect.lean's. Also for case (ii)'s elem ψ(s/2)/2: |im(s/2)| ≥ 5 ✓ sub-log: ‖ψ(s/2)‖ ≤ ‖log(s/2)‖ + 3 ≤ log(R/2) + π + 3. And case (i) (re ≥ 2) elem ψ(s/2): re(s/2) ≥ 1: hmm — (B) needs re ≥ 2: re(s/2) ∈ [1, ...): |im(s/2)| ≤ 5 (case (i) includes both |im| ≤ 10-ish... case (i) is re s ≥ 2 with ANY im: |im(s/2)| arbitrary! For |im(s/2)| ≥ 2: sub-log bound (|im w| ≥ 2 ✓). For |im(s/2)| < 2: re(s/2) ≥ 1: (A) with c = 1: dist(s/2, −ℕ) ≥ 1 (re ≥ 1) ⟹ 48+23·log(2+‖s/2‖) ✓. Uniform: ‖ψ(s/2)‖ ≤ 48 + 23·log(2+R/2)·... sub-log: ‖ψ‖ ≤ log‖s/2‖+π+3 ≤ 48+23·log(2+‖s/2‖) ✓ covered. So for ALL s on the circle: ‖ψ(s/2)‖ ≤ 62 + 23·log(2+R/2) UNIFORMLY (the max of the three: 48, 62, sub-log-absorbed) — a single elem bound! ‖ψ(s/2)/2‖ ≤ 31 + 12·log(2+R/2) ≤ 31 + 12·L. OK — so the digamma-right lemma `digamma_right_le`: for re w ≥ 1.75: ‖ψ w‖ ≤ 48 + 23·log(2+‖w‖). Via: |im w| ≥ 5: sub-log; else re ≥ 2: (B); else (A) c = 1. Now — let me check the exact signatures I need. Let me look at: 1. LiDisc.lean capstone `logDeriv_riemannZeta_sub_nearZeros_le` — the nearZeros def + the exact statement. 2. LiReflect.lean: `logDeriv_riemannZeta_sub_nearZeros_le_left`, `logDeriv_zeta_fe`, `norm_digamma_sub_log_le_of_two_le_abs_im`, the norm-log lemma (‖log w‖ ≤ log‖w‖ + π). 3. LiDigammaLeft.lean: `norm_digamma_le_of_two_le_re` (B), `norm_digamma_le_of_dist_nat` (A), `logDeriv_Gammaℝ_eq` (G). 4. LiFEntire.lean: Fexpr's exact definition. Let me grep those.
Continuing with session 033: **ii′-5e-v-c** — the logDeriv/elem assembly ⟹ ‖Fexpr‖ ≤ C·(log R)³. STATE.md's NEXT ACTION is fresh in context (I wrote it at yesterday's closure). First, pull the exact signatures of the 5c/5d/5e-ii capstones I'll assemble.

Good. Key signatures: - `logDeriv_riemannZeta_sub_nearZeros_le {t : ℝ} (ht : 10 ≤ |t|) {s : ℂ} (hsim : s.im = t) (hσlo : 1/2 ≤ s.re) (hσhi : s.re ≤ 7/2) (hs0 : riemannZeta s ≠ 0) : ‖logDeriv ζ s − Σ_{ρ ∈ nearZeros t} (zeroMult ρ:ℂ)/(s−ρ)‖ ≤ 100000·(log|t|)²` - `logDeriv_riemannZeta_sub_nearZeros_le_left {t} (ht : 10 ≤ |t|) {s} (hsim : s.im = t) (hσlo : −5/2 ≤ s.re) (hσhi : s.re ≤ 1/2) (hs0 : ζ s ≠ 0) : ... ≤ 200000·(log|t|)²` - `nearZeros t := (zeroDiscFinset t).filter fun ρ => |ρ.im − t| < 1` — a Finset ℂ. zeroDiscFinset t — the zeros in the disc around 2+it. Elements: zeros (IsNontrivialZero? zeroDisc_isNontrivial — from session 023: zeroDisc_isNontrivial). - `norm_digamma_sub_log_le_of_two_le_abs_im {w : ℂ} (hw : 2 ≤ |w.im|) : ‖Complex.digamma w − Complex.log w‖ ≤ 3`. - `logDeriv_zeta_fe` — needs 10 hypotheses (hs0, hs1, hG : Gammaℝ s ≠ 0, hζ : ζ s ≠ 0, hd : DifferentiableAt Gammaℝ s, and the same at 1−s). Now check LiDigammaLeft's (A), (B), (G) and LiReflect's norm-log lemma, plus the nearZeros count input (zeroDiscFinset's count — for the near sum I need Σ_{ρ ∈ nearZeros t} zeroMult ρ: is there a count? Or I bound via the im-band brick on the image... the nearZeros t elements are ℂ (not the subtype) — my brick is for the subtype finset. The nearZeros count: Ncount(t−1, t+1]-ish — hmm: nearZeros t ⊆ zerosIn(t−1, t+1) ∪ zerosIn(−t−1, −t+1)? The elements ρ ∈ nearZeros t have |γ−t| < 1: if γ > 0: γ ∈ (t−1, t+1) — hmm t could be negative! t = s.im ∈ [−R, R]. The brick works on the subtype with the band a ≤ |γ| ≤ b: |γ| ∈ (|t|−1, |t|+1): a := |t|−1, b := |t|+1, c := ... |γ| ≥ |t|−1 ≥ 9 ≥ 1 ✓. But nearZeros t is a Finset ℂ — the subtype finset: map? The mult-sum Σ_{ρ ∈ nearZeros t} (zeroMult ρ : ℝ) — I can bound via the brick applied to a subtype finset whose image ⊆ nearZeros... OR simpler: use Ncount directly: nearZeros t's elements with γ > 0 are in zerosIn(t−1, t+1]; with γ < 0 in zerosIn(−t−1, −t+1]... but nearZeros is a Finset ℂ and the Ncount bridge (finsum_mem_eq_finite_toFinset_sum) works on zerosIn's toFinset: Σ_{ρ ∈ nearZeros t} m ≤ Σ_{W1.toFinset ∪ W2.toFinset} m = Ncount + Ncount — the same image-subset pattern as the brick but with nearZeros t directly (no Subtype.val image needed — it's already ℂ)! Even simpler than the brick. Then Ncount(t−1, t+1] ≤ A₀·3·log(3·max|t−1||t+1|+5) (interval_gen: b−a+1 = 3) and Ncount(−t−1, −t+1] similarly: total ≤ 6·A₀·log(3(|t|+1)+5). Wait — are all elements of nearZeros t nontrivial zeros? zeroDisc_isNontrivial (session 023: zeroDisc_isNontrivial : ρ ∈ zeroDiscFinset t → IsNontrivialZero ρ? something like that — yes: "zeroDiscFinset + zeroDisc_isNontrivial (re ≥ 1 via Mathlib's one_le_re nonvanishing; re ≤ 0 via ΓR-pole/FE)"). So zerosIn membership OK (zerosIn requires IsNontrivialZero). Also — do I know |γ − t| < 1 ⟹ sign analysis: γ ∈ (t−1, t+1): if t > 0: γ > t−1 ≥ 9 > 0 ✓ all in W1?? WAIT — if t ≥ 10: γ ∈ (t−1, t+1) ⊆ (9, ...): γ > 0 ✓ — then ALL nearZeros are in zerosIn(t−1, t+1] — only ONE window needed! Similarly t ≤ −10: γ ∈ (t−1, t+1) ⊆ (−11, −9): all negative: zerosIn(t−1, t+1] = zerosIn(t−1, t+1] with both negative — one window! So the count is ONE Ncount(t−1, t+1] ≤ A₀·3·log(3·max|t−1||t+1|+5). Even simpler. (t = s.im fixed sign.) ✓ But — Ncount counts zerosIn (a, b] — membership needs a < γ ≤ b: |γ−t| < 1 ⟹ t−1 < γ < t+1 ⟹ γ ∈ (t−1, t+1) ⊆ (t−1, t+1] ✓ (non-strict upper fine). So near-count: Σ_{ρ ∈ nearZeros t} (zeroMult ρ : ℝ) ≤ Ncount(t−1, t+1] ≤ 3·A₀·log(3·max|t−1||t+1|+5) — via sum_le_sum_of_subset_of_nonneg + the finsum bridge. Need nearZeros t ⊆ (zerosIn (t−1) (t+1)).toFinset. ✓ Now the (A)/(B)/(G) from LiDigammaLeft:
Now the 5e-ii digamma API and the norm-log lemma from LiReflect.

Cases: - re(s/2) ≤ 2 hmm — actually simplest uniform: split on re(s/2) ≤ 2 vs ≥ 2 hmm — but the dist-based (A) needs re ≤ 2 and dist(w,−ℕ) ≥ c. For the circle points with re(s/2) ≤ 2: dist(s/2, −ℕ) ≥ ? Two sub-cases: |im(s/2)| ≥ 5: sub-log: ‖ψ‖ ≤ 3 + log‖s/2‖ + π ≤ 62+23·log(2+‖s/2‖) ✓ (3+π ≤ 7 ≤ 62 ✓). |im(s/2)| < 5: then |re s| ≥ √(R²−100) hmm — |im s| < 10 ⟹ |re s| ≥ √(R²−100) ⟹ |re(s/2)| ≥ √(R²−100)/2 ≥ ~R/2: either re(s/2) ≥ R/2-ish ≥ 2 (use digamma_right_le: 48+23·log) or re(s/2) ≤ −√(R²−100)/2 (the left near-axis: dist(s/2,−ℕ) ≥ 1/8 from the ℤ-clearance: (A) c = 1/8: 46+16 = 62 ✓). So `digamma_circle_le` needs the dist-argument for the left near-axis — which needs the hgapInt property (dist(R/2,ℤ) ≥ 1/4). So the Fexpr circle bound theorem will take hgapInt as a hypothesis (from exists_gapCircle_radius's third component). The dist-lower-bound: for s with ‖s‖ = R, |im s| < 10, re s < 0 (the left near-axis): dist(s/2, −ℕ) ≥ 1/8: ∀ m : ℕ, 1/8 ≤ ‖s/2 + (m:ℂ)‖: ‖s/2+m‖ ≥ |re(s/2+m)| = |re s/2 + m|: m : ℕ: −m ∈ −ℕ: re s/2 ∈ [−R/2, −√(R²−100)/2]: |re s/2 − (−m)|: the nearest −m to re s/2: hmm — re s/2 + m: if −m is near re s/2: |re s/2 + m| ≥ dist(re s/2, −ℕ)... Let me formalize: re(s/2) = (re s)/2: re s ∈ [−R, −√(R²−100)]: re(s/2) ∈ [−R/2, −√(R²−100)/2]. Let x := re(s/2): x + R/2 ∈ [0, R/2 − √(R²−100)/2] — R/2 − √(R²−100)/2 = (R−√(R²−100))/2 = 50/(R+√(R²−100)) ≤ 50/R ≤ 26/R·... (R−√(R²−100))/2: R−√(R²−100) = 100/(R+√(R²−100)) ≤ 100/R: so x + R/2 ≤ 50/R. Hmm the design said 26/R: with √(R²−100) ≥ 0: R−√(R²−100) = 100/(R+√(R²−100)) ≤ 100/R: /2 = 50/R. For R ≥ 400: 50/R ≤ 1/8. R ≥ 16002 ✓ (50/16002 < 1/8 ⟺ 400 < 16002 ✓). dist(x, −ℕ): x ∈ [−R/2, −R/2+50/R]: write x = −R/2 + u, u ∈ [0, 50/R]: for m : ℕ: x + m = u + (m − R/2): |x + m| ≥ |m − R/2| − u ≥ 1/4 − 50/R ≥ 1/4 − 1/8 = 1/8 ✓ where |m − R/2| = |R/2 − m| ≥ 1/4 by hgapInt (m : ℤ).

Let me use: have : (s/2).re = s.re/2 := by simp [Complex.div_re, Complex.ofNat_re]... might need `Complex.ext`... Actually simpler: (s/2 + (m:ℂ)).re = s.re/2 + m: via simp [Complex.add_re, Complex.div_re, Complex.ofNat_re, Complex.natCast_re]. Then |(re s)/2 + m| ≥ 1/8: the above u-argument with hgapInt (m : ℤ): |R/2 − (m:ℝ)| ≥ 1/4: hgapInt's form: ∀ m : ℤ, 1/4 ≤ |R/2 − (m:ℝ)| ✓ (from exists_gapCircle_radius).

Need: (re s)/2 + R/2 ∈ [0, 50/R]: (re s)/2 ≥ −R/2 (re s ≥ −R: |re s| ≤ R ✓ abs_re_le_norm+hs) ⟹ (re s)/2 + R/2 ≥ 0 ✓; (re s)/2 ≤ −√(R²−100)/2 hmm — the upper: re s ≤ −√(R²−100) (this is the LEFT near-axis case: re s < 0 and |im s| < 10 ⟹ re² > R²−100 ⟹ re s < −√(R²−100) ✓). (re s)/2 + R/2 ≤ (R − √(R²−100))/2 = 50/(R+√(R²−100)) ≤ 50/R ✓ — the R−√(R²−100) = 100/(R+√(R²−100)) identity: (R−√)(R+√) = R²−(R²−100) = 100 (mul_self_sub_mul_self + Real.mul_self_sqrt). ~15 lines. Hmm wait — is the sqrt route needed? Alternative: avoid √: re s < 0, |im s| < 10: re² = R²−im² > R²−100: (re s)/2 + R/2 = (R + re s)/2: R+re s = (R²−re²)/(R−re s) = im²/(R−re s) ≤ 100/R (im² ≤ 100, R−re s ≥ R): so (re s)/2+R/2 = (R+re s)/2 ≤ 50/R ✓ NO SQRT NEEDED. R+re s ≥ 0 ✓ (re s ≥ −R). And the identity R+re s = im²/(R−re s): (R+re s)(R−re s) = R²−re² = im² (normSq) ⟹ R+re s = im²/(R−re s) (R−re s ≠ 0: R−re s ≥ R > 0 ✓). So `digamma_circle_le {s} (hs : ‖s‖ = R) (hgapInt : ∀ m : ℤ, 1/4 ≤ |R/2 − (m:ℝ)|) (hR : 16002 ≤ R) : ‖Complex.digamma (s/2)‖ ≤ 62 + 23 * Real.log (2 + R/2)`.

For re(s/2) < 1.75 with |im(s/2)| < 5: |re(s/2)| ≥ ... |im s| < 10 ⟹ |re s| ≥ √(R²−100) — UGH sqrt again. Avoid: |im(s/2)| < 5 ⟹ |im s| < 10 ⟹ (re s)² = R² − (im s)² > R² − 100 ⟹ |re s| > √(R²−100)... just need re s ∉ (−5, 5)-ish: (re s)² > R²−100 ⟹ |re s| > R−... |re s| ≥ R−50/R: (R−|re s|)(R+|re s|) = im² < 100: R−|re s| < 100/(R+|re s|) ≤ 100/R: |re s| > R−100/R. So |re(s/2)| > R/2−50/R. With re(s/2) < 1.75: re(s/2) ∈ (−R/2+50/R)... re(s/2) < 1.75 and |re(s/2)| > R/2−50/R ≥ R/2−1 (50/R < 1): so re(s/2) < −(R/2−50/R) (negative branch since |re(s/2)| > R/2−50/R ≥ 1.75 would contradict if positive... |re(s/2)| > R/2−50/R ≥ R/2−1 ≥ 1.75 for R ≥ 6: so re(s/2) is either > 1.75 (contradiction) or < −1.75: hence re(s/2) < −1.75 < 0 ✓). So re(s/2) < 0, |re(s/2)| > R/2−50/R: i.e. (re s)/2 ∈ [−R/2, −(R/2−50/R)): (re s)/2 + R/2 ∈ [0, 50/R). Then the dist argument: (A) c = 1/8: hwre : (s/2).re ≤ 2 ✓ (re(s/2) < 0 ≤ 2): hdist ∀ m, 1/8 ≤ ‖s/2+m‖ ✓ (the u-argument). Result: 62+23·log(2+‖s/2‖) = 62+23·log(2+R/2) ✓ (‖s/2‖ = ‖s‖/2 = R/2: norm_div, norm_ofNat... ‖s/2‖ = ‖s‖/‖(2:ℂ)‖ = R/2 ✓). Summary of digamma_circle_le cases: (a) 5 ≤ |im(s/2)|: sub-log.

Case ‖ρ‖ > R−2: then ρ ∈ crit-shell (‖ρ‖ ∈ (R−2, R+2)) AND ρ ∈ circleZeros R (‖ρ‖ < R+2 ≤ 2R+1 ✓): shell_crit's hsep — BUT hsep is LOCAL to shell_crit (inside its proof). I need the separation as a STANDALONE lemma! Extract: `gapCircle_sep {k} (hk) {R} (hRlo) (hgap) {s} (hs : ‖s‖ = R) (hsz) {ρ : ℂ} (hρ : IsNontrivialZero ρ) (hρnorm : R−2 < ‖ρ‖ ∧ ‖ρ‖ < R+2) : 1/(32·Ĉ₀) ≤ ‖s − ρ‖`. Then shell_crit uses it too — hmm, shell_crit is already proved with the inline version. For 5e-v-c I'll prove the standalone `gapCircle_sep` (the same proof, taking ρ : ℂ with IsNontrivialZero instead of the subtype) and use it in the near-sum; shell_crit stays as is (duplication acceptable — or refactor shell_crit to use it; cleaner to refactor but the freeze protocol... LiCircleBound is THIS tier's file, editable. Simplest: prove standalone gapCircle_sep and leave shell_crit untouched (its inline proof already works — no need to touch). Case ‖ρ‖ ≤ R−2: ‖s−ρ‖ ≥ R−‖ρ‖ ≥ 2 ≥ 1/(32Ĉ₀) ✓. Also need hsz (s not a nontrivial zero — from not_isNontrivialZero_on_gapCircle) — only for the identity, not for the separation. Wait — the separation proof in shell_crit used the hgap on ρ OR conj ρ (both nontrivial) ✓ works for ρ : ℂ with IsNontrivialZero ρ ✓. And the t := s.im, γ := ρ.im arc analysis ✓ same.

For im s = 0 (s = −R): the continuity extension. The bound B(s) := dirichletC2 + 69+24L is CONTINUOUS-free (a constant); the function s ↦ logDeriv ζ s is continuous at −R (ζ analytic + nonzero at −R ⟹ logDeriv continuous). And the bracket-bound holds at nearby arc points with im ≠ 0... but actually — the FE identity at s = −R ALSO holds (logDeriv_zeta_fe's hyps all checkable at −R ✓): logDeriv ζ(−R) = −logDeriv ζ(1+R) − (logDeriv ΓR(−R) + logDeriv ΓR(1+R)). The issue is only EVALUATING logDeriv ΓR(−R) — (G) needs im ≠ 0. So: continuity of logDeriv ΓR at −R + the formula on im ≠ 0 dense ⟹ the bound ‖logDeriv ΓR s + logDeriv ΓR(1−s)‖ ≤ 69+24L at s = −R by taking limits: the function s ↦ ‖logDeriv ΓR s + logDeriv ΓR(1−s)‖ is continuous at −R (logDeriv ΓR continuous at −R and at 1+R ✓ both Gammaℝ nonzero + differentiable) and bounded by C on the dense set {arc points with im ≠ 0} ⟹ ≤ C at −R (continuous + closure: ‖f(−R)‖ = lim ‖f(sₙ)‖ ≤ C).

Something like: le_of_tendsto_of_tendsto (hf : Tendsto f l (𝓝 a)) (hg : Tendsto g l (𝓝 b)) (h : ∀ᶠ x, f x ≤ g x) : a ≤ b with g := const C.) This adds ~50-60 lines. Alternatively — handle s = −R directly: prove logDeriv_Gammaℝ_eq AT the real point too via continuity of both sides: both sides continuous at −R (logDeriv ΓR continuous; the RHS: digamma(s/2) continuous at −R/2 (analyticAt_digamma: −R/2 ∉ {0}∪−ℕ: dist(R/2,ℤ) ≥ 1/4 ⟹ R/2 ∉ ℤ... wait −R/2: is −R/2 ∈ {0}∪−ℕ? −R/2 = −m ⟺ R/2 = m ∈ ℤ — excluded ✓; = 0 no). So RHS continuous at −R) and equal on the dense im ≠ 0 ⟹ equal at −R (continuous extension of equality — Tendsto uniqueness: f − g continuous, = 0 on dense ⟹ = 0 at the point). That's the SAME continuity machinery but applied to the equality — equally heavy. OK, do the norm-continuity bound route. Hmm — actually, EVEN SIMPLER: note that at s = −R, instead of (G), evaluate the bracket bound DIRECTLY: ‖logDeriv ΓR(−R) + logDeriv ΓR(1+R)‖ — both arguments real. logDeriv ΓR(1+R): (1+R)/2: re > 0 big — hmm still needs (G). No way around: (G) is im ≠ 0 only. The continuity route it is. WAIT — actually, do I even need the bracket at s = −R via (G)? There's `logDeriv_Gammaℝ_shift` from 5d (the +4 shift used in the left capstone): `logDeriv ΓR s = logDeriv ΓR (s+4) − (1/s + 1/(s+1) + 1/(s+2) + 1/(s+3))`-ish — and 5d's left capstone uses StirlingVert's digamma_stirling on the shifted. For s = −R: logDeriv ΓR(−R) = logDeriv ΓR(4−R) − Σ 1/(−R+j): and digamma_stirling for the shifted (re(4−R) < 0 still...). Hmm the 5d machinery shifts by +4 to get digamma args in re > 0: logDeriv ΓR s = −(logπ)/2 + ½ψ(s/2) — the 5d proof of the bracket bound used logDeriv_Gammaℝ_shift + digamma_stirling — did 5d prove a BRACKET bound ≤ 4(log|t|)²? Yes: "the ΓR-bracket ≤ 4(log|t|)² (the +4 ΓR shift logDeriv_Gammaℝ_shift putting both digamma arguments in re > 0 + StirlingVert digamma_stirling)". That bound is for |t| ≥ 10 — at s = −R, t = 0 — not applicable. OK, continuity route it is. Actually hold on — for s = −R (real), maybe the cleanest: ψ(s/2) at s = −R: s/2 = −R/2: dist(−R/2, −ℕ) ≥ 1/4 (hgapInt) ⟹ digamma analytic at −R/2 ✓ and the (G) formula at −R: prove by the continuity-of-equality on the dense set... I'll do the norm-continuity bound route for the whole case (iii) at im = 0 — single use point (s = −R; also any other circle point with im = 0 is just ±R, and +R is region (i) ✓ — so ONLY s = −R needs it). Let me now define the exact region split for the logDeriv bound: - (i) 2 ≤ re s: Dirichlet. - (ii) −5/2 ≤ re s ∧ re s ≤ 2 hmm wait 5c needs re ≥ 1/2 and 5d-left needs re ≤ 1/2: union [−5/2, 7/2]: with (i) covering re ≥ 2: let region (ii) := −5/2 ≤ re s ∧ re s < 2: split at 1/2: [1/2, 2) → 5c (re ≤ 7/2 ✓ 2 ≤ 7/2 ✓); [−5/2, 1/2) → 5d-left (re ≤ 1/2 ✓). At re = 1/2 either works ✓ use 5c. - (iii) re s < −5/2: FE. Coverage: re ≥ 2 / −5/2 ≤ re < 2 / re < −5/2 ✓ all. The |t| ≥ 10 for region (ii): re ∈ [−5/2, 2] ⟹ re² ≤ 25/4 ⟹ im² = R²−re² ≥ R²−25/4: |im| ≥ √(R²−25/4) — avoid sqrt: |im| ≥ R−(25/4)/R·... R−|im| = re²/(R+|im|) ≤ (25/4)/R: |im| ≥ R−25/(4R) ≥ 10 ⟺ 25/(4R) ≤ R−10 ⟸ R ≥ 16002 ✓ linarith. 5. The elem bounds: 1/s, 1/(s−1), log π/2, ψ(s/2)/2: - ‖(1:ℂ)/s‖ = 1/‖s‖ = 1/R ≤ 1 (norm_div, norm_one, hs). - ‖1/(s−1)‖ = 1/‖s−1‖ ≤ 1/(R−1) ≤ 1 (‖s−1‖ ≥ ‖s‖−‖(1:ℂ)‖ = R−1 ≥ 1; 1/(R−1) ≤ 1 ⟺ R ≥ 2). - ‖(Real.log Real.pi : ℂ)/2‖ = (log π)/2 ≤ 1: log π ≤ 2: π ≤ e²: Real.pi_lt_315 (π < 3.15) hmm need log π ≤ 2: π ≤ e^2 ⟸ e^2 ≥ 7.29 > 3.15 > π ✓: Real.log_le_log (pi_pos) (π ≤ e^2): π < 3.15 ≤ 7.29 ≤ e^2 (e^2 ≥ 2.7² = 7.29 ✓).

And the cast is (Real.log Real.pi : ℂ): ‖(log π:ℂ)/2‖ = |log π|/2 = (log π)/2 (log π ≥ 0: π ≥ 1: Real.log_nonneg (le_of_lt Real.pi_gt_one... pi > 3.14 > 1)). - ‖digamma (s/2)/2‖ = ‖digamma (s/2)‖/2 ≤ (62+23·log(2+R/2))/2. 6. **The assembly** `Fexpr_circle_le`: ``` theorem Fexpr_circle_le {k : ℕ} (hk : 4000 ≤ k) {R : ℝ} (hRlo : 4*(k:ℝ)+5/2 ≤ R) (hRhi : R ≤ 4k+3) (hgap : ...)

Actually for the squeeze, ANY fixed constants are fine. Keep the form.

Each piece bounded as computed. Ĉ₀(4k+9/2) ≤ Ĉ₀(R+2) via C0hat_mono (4k+9/2 ≥ 1 ✓, 4k+9/2 ≤ R+2 ⟺ 4k+5/2 ≤ R ✓ hRlo). Budget check with the actual haves: - series: 2·lowZeroConst + 2900·A₀·Ĉ₀(4k+9/2)·L² ≤ 2·lowZeroConst + 2900·A₀·Ĉ₀(R+2)·L² ✓. - logDeriv: max over regions: (i) dirichletC2; (ii) 200000·L²+192Ĉ₀A₀L² (with Ĉ₀(4k+9/2) → Ĉ₀(R+2) — WAIT: the separation 1/(32Ĉ₀) uses Ĉ₀(4k+9/2) (the gap property is stated with it) ✓ keep consistent, convert at the end); (iii) dirichletC2 + (log π + 69+24L)-ish ≤ dirichletC2 + 100·A₀Ĉ₀L².

So final constant 400000 fits with room. Order of build: - c-i: `gapCircle_sep` (standalone separation, ~100 lines — adapted from shell_crit's hsep but for ρ : ℂ directly) + `nearZeros_count_le` (~60) + the near-sum bound (~80). - c-ii: `digamma_right_le` (~50) + `digamma_circle_le` (~120) + the small elems (~60). - c-iii: `logDeriv_circle_le` (~200 incl. the FE region + the s = −R continuity) + `Fexpr_circle_le` assembly (~80). The s = −R continuity: hmm — let me think about whether I can AVOID it. At s = −R: I need ‖logDeriv ΓR(−R) + logDeriv ΓR(1+R)‖ ≤ bracket. What if I bound the two logDeriv ΓR values SEPARATELY via the m-shift recurrence to a (G)-applicable point? logDeriv ΓR(−R) = logDeriv ΓR(−R+2i·...)? No — the recurrence is in the REAL direction (Gamma_add_one): logDeriv ΓR(s) = logDeriv ΓR(s+2) − (1/s + 1/(s+2))-ish (ΓR(s+2) = (s/2)·ΓR(s)?? Gammaℝ(s+2) = (s/2)·Gammaℝ(s): logDeriv: logDeriv ΓR(s+2)·(s+2)... hmm: ΓR(s+2) = (s/2)ΓR(s) ⟹ logDeriv ΓR(s) = logDeriv ΓR(s+2)·... the 5d `logDeriv_Gammaℝ_shift` already does a +4 shift chain: logDeriv ΓR s = logDeriv ΓR (s+4) − [1/s·2-ish terms]. For s = −R: logDeriv ΓR(−R) = logDeriv ΓR(4−R) − Σ_{j=0}^{3} (digamma-shift terms): and at (4−R): im still 0! (G) STILL not applicable (real point). ARGH. The (G) restriction is im ≠ 0 — every real point needs the continuity argument. OK, continuity route. Actually — WAIT. Alternative: prove (G) at real non-pole points too, by the identity principle! Both sides of `logDeriv ΓR s = −(log π)/2 + ½ψ(s/2)` are analytic on the connected open set ℂ ∖ ({0} ∪ −2ℕ-ish poles) hmm — logDeriv ΓR analytic where ΓR ≠ 0 and differentiable: off {−2ℕ}. The set U := ℂ ∖ (−2ℕ)?? hmm: ΓR(s) = π^{−s/2}Γ(s/2): poles where s/2 ∈ −ℕ ⟺ s ∈ −2ℕ∪{0}?? Γ(s/2) poles at s/2 ∈ {0,−1,−2,...} ⟺ s ∈ {0,−2,−4,...} = −2ℕ. And ΓR ≠ 0 everywhere else (Γ has no zeros). So both sides analytic on U := ℂ \ {0,−2,−4,...} — wait also need s/2 ∉ {0}∪−ℕ for digamma(s/2) — same set. U = ℂ ∖ {s : ∃ m:ℕ, s = −2m}: connected? ℂ minus a discrete set is connected ✓. The formula holds on {im ≠ 0} ⊆ U — which has a limit point in U ✓ (e.g. 1). Identity principle: AnalyticOnNhd.eq_of_isPreconnected_eq... Mathlib: `AnalyticOn.eqOn_of_preconnected_of_eventually_eq`? or `AnalyticOnNhd.eq_of_frequently_eq`? The journal-020 pattern used "identity principle" — let me grep for what was used. This is ~40 lines if the API cooperates. Then (G) holds at ALL non-pole points including −R. That's cleaner than the sequence-tendsto (no explicit sequence construction). Let me check what identity-principle API was used before (LiDigamma.lean "complex series by Weierstrass + identity principle"). Let me grep for the identity principle usage in the repo.
All signatures in hand. The s = −R (real point) needs the (G) formula off `im ≠ 0` — check which identity-principle API was used before in this repo.

No direct Mathlib `logDeriv Gamma = digamma`. OK, so the identity-principle route for extending (G) to the real non-pole points. Let me look at how `logDeriv_Gammaℝ_eq` is proved (5e-ii) — maybe its proof generalizes easily, or maybe there's a differentiability lemma for Gammaℝ I can use for the identity principle. The plan for `(G)-extended`: ``` lemma logDeriv_Gammaℝ_eq_of_not_neg_two_nat {s : ℂ} (hs : ∀ m : ℕ, s ≠ -2 * (m : ℂ)) : logDeriv Complex.Gammaℝ s = -(Real.log Real.pi : ℂ) / 2 + (1/2 : ℂ) * Complex.digamma (s / 2) ``` via the identity principle on U := {s | ∀ m, s ≠ −2m}: - U is open (complement of a discrete set — hmm, proof: the set {−2m} is locally finite... This could be annoying. Alternative: prove the identity DIRECTLY at each real point via a punctured-neighborhood continuity: both sides continuous at s₀ = −R (real, non-pole), equal on the punctured ball (im ≠ 0 points are dense in the ball) ⟹ equal at s₀. The continuity-of-equality at a point: f, g continuous at s₀, f = g on 𝓝[≠] s₀ (a dense punctured nbhd) ⟹ f s₀ = g s₀. This is `ContinuousAt.eq_of_eventuallyEq`? Hmm — more precisely: if f and g are continuous at s₀ and f =ᶠ[𝓝[≠] s₀] g, then f s₀ = g s₀. That's from tendsto uniqueness: Tendsto f (𝓝[≠] s₀) (𝓝 (f s₀)) (continuity restricted) and g similarly with f =ᶠ g ⟹ f s₀ = g s₀ via tendsto_nhds_unique — needs 𝓝[≠] s₀ to be non-trivial (NeBot — in ℂ every point is a limit point ✓ `neBot_nhdsWithin` or `ContinuousAt.eventuallyEq`...). Actually — the cleanest might be: prove the identity holds on the punctured ball around −R (via (G), since those points have im ≠ 0... wait NO — a punctured ball around −R contains only... the ball around −R contains points with im = 0 (other real points ≠ −R — hmm real points near −R: R ∈ [4k+2.5, 4k+3]: the real points near −R are −R±ε: are THEY poles? −2m would need R±ε = 2m: only if R = 2m exactly — but dist(R/2,ℤ) ≥ 1/4 excludes R/2 ∈ ℤ — but nearby reals R±ε: R/2±ε/2 could hit an integer? dist(R/2,ℤ) ≥ 1/4 ⟹ within ±1/8 of R/2 no integer ✓ so for ε < 1/4: (R±ε)/2 ∉ ℤ ✓ so real points in ball(−R, 1/8) are all non-pole ✓). Hmm — but (G) applies only at im ≠ 0 points. The continuity-of-equality: f := logDeriv ΓR, g := −(logπ)/2+½ψ(s/2): both continuous at s₀ (−R): - f continuous: logDeriv ΓR continuous at s₀: ΓR differentiable at s₀ (s₀/2 ∉ −ℕ: dist(R/2,ℤ) ≥ 1/4 ⟹ R/2 ∉ ℤ ✓ — need differentiableAt_Gammaℝ: what discharges hd in the 5d applications? Let me grep) and ΓR(s₀) ≠ 0 (Gammaℝ_eq_zero_iff) ⟹ logDeriv continuous (DifferentiableAt.logDeriv? there's `DifferentiableAt.logDeriv`? logDeriv = deriv/f: continuous when f cont, f' cont?? deriv isn't continuous in general — but for ANALYTIC f, deriv is analytic ⟹ continuous ✓: (analyticAt_Gammaℝ s₀).deriv.continuousAt.div (analyticAt continuous) (nonzero). So need analyticAt_Gammaℝ at s₀. - g continuous: digamma(s/2) analytic at s₀/2 = −R/2 (−R/2 ∉ {0}∪−ℕ ✓ via analyticAt_digamma from LiFEntire) ⟹ continuous. - equal on ball(−R, 1/8) \ {im = 0}?? no — on {im ≠ 0} ∩ ball: dense: 𝓝[≠] s₀ contains all im ≠ 0 nearby points... the equality f = g holds on {im ≠ 0} (by (G)) which is cofinite-dense: the set {s : s.im ≠ 0} ∈ 𝓝[≠] s₀? {im = 0} is the real line — its complement is dense and open: {im ≠ 0} is open dense ⟹ ∈ 𝓝[≠] s₀ for any s₀ (a punctured nbhd contains it — actually {im ≠ 0} ∪ {s₀} is a nbhd of s₀ since it's open dense... {im ≠ 0} ∪ {s₀} = ℂ ∖ ({im = 0} ∖ {s₀}) — open? {im=0}∖{s₀} is closed (real line minus a point — closed ✓): complement open ✓ contains s₀ ✓. So {im≠0} ∪ {s₀} ∈ 𝓝 s₀ ⟹ {im ≠ 0} ∈ 𝓝[≠] s₀ (nhdsWithin_mem: s ∈ 𝓝[≠] s₀ iff s ∪ {s₀} ∈ 𝓝 s₀ ✓ `nhdsWithin_mem_iff`?). Then f =ᶠ[𝓝[≠] s₀] g (eventually on that set ✓). - Then f s₀ = g s₀: from both continuous at s₀: ContinuousAt f s₀ : Tendsto f (𝓝 s₀) (𝓝 (f s₀)) ⟹ Tendsto f (𝓝[≠] s₀) (𝓝 (f s₀)) (tendsto_nhdsWithin... ContinuousAt.tendsto_nhdsWithin? there's `ContinuousAt.tendsto_nhdsWithin` or just mono: Tendsto.mono_left inf_le_left... nhdsWithin s₀ {s₀}ᶜ ≤ 𝓝 s₀ hmm: 𝓝[≠] s₀ = 𝓝 s₀ ⊓ 𝓟 {s₀}ᶜ ≤ 𝓝 s₀ ✓ Tendsto.mono h inf_le_left). Similarly g. Then tendsto_nhds_unique (neBot of 𝓝[≠] s₀ in ℂ — `instNeBotNhdsWithinCompl`? there's `(𝓝[≠] s₀).NeBot` instance in T2 spaces... `nhdsWithin_compl_neBot`? In ℂ: `Complex` is a perfect space: NeBot (𝓝[≠] x) ✓ instance exists) applied to the EventuallyEq. So the s = −R identity is ~40 lines. And then the WHOLE case (iii) uses the identity at all points (im ≠ 0 via (G), im = 0 via the extension — but actually for im ≠ 0 I can ALSO just use the extended version — so the extension REPLACES (G) usage in case (iii) entirely if I prove the extended version for all non-pole s. Hmm — but the extension is pointwise continuity at each real point; for im ≠ 0 points (G) applies directly. So: `logDeriv_Gammaℝ_eq'` : ∀ s with (∀ m, s ≠ −2m) (im ≠ 0 OR real): just do two lemmas: use (G) for im ≠ 0; for s₀ real (im = 0) non-pole: the continuity extension `logDeriv_Gammaℝ_eq_of_im_eq_zero`. ~50 lines. Only needed at s₀ = −R (the only real point on the left arc — and right arc's +R: region (i) doesn't need (G) ✓). Actually — simpler alternative for the im = 0 case: I realize the identity principle on the connected open set U = {s : ∀ m, s ≠ −2m} is NOT obviously less work (proving U open + both sides AnalyticOnNhd). The pointwise continuity route is more elementary. Let me go with the pointwise route. Hmm wait — actually even simpler: for s₀ = −R, apply (G) at the sequence points and take the LIMIT of the inequality ‖bracket‖ ≤ C: no — the identity itself is what I need... The norm-continuity route: I need ‖logDeriv ΓR s₀ + logDeriv ΓR(1−s₀)‖ ≤ C: the function F(s) := ‖logDeriv ΓR s + logDeriv ΓR(1−s)‖ is continuous at s₀ (both logDeriv ΓR continuous at s₀ and at 1−s₀) and F(s) ≤ C for all s in the dense set D := {im ≠ 0} ∩ (the left arc... — actually for ALL im ≠ 0 points with the right re-range — the bound derivation used re s < −5/2 etc. — for nearby points s of s₀ = −R on the circle with im ≠ 0: those satisfy the case-(iii) conditions ✓ (continuity of re: nearby s have re < −5/2 ✓ — well, on the ARC: the bound was proved for all arc points with re < −5/2 and im ≠ 0: s₀ = −R has re = −R < −5/2 ✓: the arc points near s₀: a punctured BALL around s₀ ∩ {im ≠ 0} ∩ {circle}... the bound F ≤ C holds on {im ≠ 0} ∩ ball(s₀, δ)-ish? NO — the case-(iii) bound holds for s ON THE CIRCLE with re s < −5/2. For the continuity I need F ≤ C on a set accumulating at s₀ — the arc points near s₀ with im ≠ 0 form such a set: {s : ‖s‖ = R ∧ im s ≠ 0 ∧ dist s s₀ < δ}: nonempty for all δ (arc is 1-dimensional: pick s = R·e^{i(π±ε)} ✓). Tendsto along that set: F(s₀) = lim F(s) ≤ C ✓ — but constructing the explicit sequence sₙ = R·e^{i(π−1/(n+1))} is the concrete way: sₙ := R * exp(I*(π − 1/(n+1))): - ‖sₙ‖ = R·‖exp(I·x)‖ = R·1 = R (Complex.norm_exp_I_mul_ofReal... norm of exp(I·x) = 1: `Complex.norm_exp_I_mul_ofReal : ‖exp (I * x)‖ = 1`? there's Complex.abs_exp_ofReal_mul_I... `Complex.norm_exp_ofReal_mul_I : ‖Complex.exp (x * I)‖ = 1` ✓). - im sₙ = R·sin(π − 1/(n+1)) = R·sin(1/(n+1)) > 0 ✓ (sin(1/(n+1)) > 0: 1/(n+1) ∈ (0, 1] ⊆ (0, π) ✓ Real.sin_pos_of_pos_of_lt_pi). - sₙ → −R: re sₙ = R·cos(π−1/(n+1)) = −R·cos(1/(n+1)) → −R·1; im → R·0 = 0: Tendsto (fun n => R·exp(I(π−1/(n+1)))) = R·exp(I·π) = R·(−1) = −R (exp(Iπ) = −1: Complex.exp_pi_mul_I? `Complex.exp_pi_mul_I : exp (π * I) = -1` ✓). Continuity of exp/mul: Tendsto.comp ✓. - Then F(sₙ) ≤ C ∀ n and F(sₙ) → F(s₀) (continuity at s₀) ⟹ F(s₀) ≤ C (le_of_tendsto_of_tendsto' hmm: `le_of_tendsto (hg : Tendsto g atTop (𝓝 b)) (h : ∀ᶠ n, g n ≤ b') : b ≤ b'` — the exact name: le_of_tendsto_of_tendsto' (hf : Tendsto f l (𝓝 a)) (hg : Tendsto g l (𝓝 b)) (h : f ≤ᶠ[l] g) : a ≤ b. With f := F∘sₙ, g := const C.) OK ~40 lines with the sequence. Hmm — but WAIT: also the FE identity at s₀ = −R (logDeriv_zeta_fe) needs differentiableAt Gammaℝ at −R and 1+R — what discharges `DifferentiableAt ℂ Complex.Gammaℝ s`? Let me grep how 5d's applications of logDeriv_zeta_fe discharged hd. Let me look at how logDeriv_zeta_fe's hypotheses were discharged in 5d (LiReflect usage) and find differentiableAt/analyticAt Gammaℝ lemmas.
Let me check how `DifferentiableAt Gammaℝ` was discharged in 5d and find the Gammaℝ differentiability API.

The proof of `differentiableAt_Gammaℝ_of_im_ne_zero'` uses `Complex.differentiableAt_Gamma _ hhalf` where hhalf : ∀ m : ℕ, s/2 ≠ −(m:ℂ) — the im ≠ 0 hypothesis is ONLY used to get s/2 off the poles! So the SAME proof works for any s with s/2 ∉ −ℕ — i.e. for s = −R with dist(R/2,ℤ) ≥ 1/4. So: ``` theorem differentiableAt_Gammaℝ_of_not_neg_two_nat {s : ℂ} (hs : ∀ m : ℕ, s ≠ -2 * (m : ℂ)) : DifferentiableAt ℂ Complex.Gammaℝ s := by have hhalf : ∀ m : ℕ, s / 2 ≠ -(m : ℂ) := by intro m h apply hs m have := congrArg (· * (2 : ℂ)) h rw [div_mul_cancel₀ s (two_ne_zero : (2 : ℂ) ≠ 0)] at this rw [this]; ring ... (identical to the im≠0 proof from hhalf on) ``` And similarly (G) at such s — via the pointwise continuity extension, OR actually — now that I have differentiability at the real non-pole points, the continuity-of-equality needs: - logDeriv ΓR continuous at s₀: (analyticAt: DifferentiableAt → AnalyticAt? No — DifferentiableAt doesn't give AnalyticAt directly... For the CONTINUITY of logDeriv (deriv f / f), I need deriv f continuous at s₀ — deriv of Gammaℝ: is Gammaℝ ANALYTIC at s₀? AnalyticAt follows from DifferentiableAt on an open set... Mathlib: `DifferentiableAt.analyticAt` doesn't exist (banked session 029: "DifferentiableAt.analyticAt does NOT exist (use fun_prop)"). Gammaℝ is analytic off poles: `Complex.analyticAt_Gammaℝ`? hmm — the fun_prop route: analyticAt Gammaℝ s₀ via AnalyticAt.mul of the two factors (both analytic: const_cpow analytic everywhere; Gamma analytic off poles: `Complex.analyticAt_Gamma _ hhalf`? there's differentiableAt_Gamma; analytic version? Mathlib has `Complex.analyticAt_Gamma`?? Let me grep. If differentiable only, then: continuity of logDeriv at s₀ via: logDeriv f = deriv f / f: deriv f continuous at s₀ iff f is C¹ at s₀: analytic ⟹ C¹. For Gamma: analyticAt: Mathlib `Complex.analyticAt_Gamma (s : ℂ) (hs : ∀ m : ℕ, s ≠ -(m:ℂ)) : AnalyticAt ℂ Gamma s`?? I recall `differentiable_Gamma`... Let me grep. Actually — hold on, maybe simpler: AnalyticAt from AnalyticOnNhd via the identity-principle route for (G)-extension. You know what — let me simplify the whole thing: I'll prove the (G)-extension via the pointwise continuity-of-equality, using: - logDeriv ΓR continuous at s₀: from DifferentiableAt ℂ (logDeriv Complex.Gammaℝ)? no. From `AnalyticAt ℂ (logDeriv Complex.Gammaℝ) s₀`: logDeriv of an analytic nonvanishing function is analytic: `AnalyticAt.logDeriv`? hmm: logDeriv f = deriv f / f: (analyticAt_f.deriv.div analyticAt_f nonzero): `AnalyticAt.deriv : AnalyticAt ℂ f x → AnalyticAt ℂ (deriv f) x` ✓ exists. Then .div with the nonzero. So I need AnalyticAt ℂ Complex.Gammaℝ s₀. Grep for analyticAt_Gamma.
The `im ≠ 0` hypothesis was only used for pole-avoidance. Check the analytic Gamma API.

`Complex.differentiableAt_Gamma (s) (hs : ∀ m : ℕ, s ≠ -m)` exists — but only DifferentiableAt, not AnalyticAt. Hmm. But wait — DifferentiableAt on an OPEN SET gives AnalyticAt? In Mathlib: `DifferentiableOn.analyticOnNhd`? or `DifferentiableOn.analyticOn` — for complex functions: differentiable on an open set ⟹ analytic there (`DifferentiableOn.analyticOn (hd : DifferentiableOn ℂ f s) (hs : IsOpen s) : AnalyticOn ℂ f s` — yes! Complex differentiability on an open set implies analyticity — Goursat's theorem is in Mathlib via `DifferentiableOn.analyticOn`). So for the continuity at s₀ = −R: Gammaℝ is differentiable on the open set U := {s | ∀ m, s/2 ≠ −(m:ℂ)} (the pole complement — hmm is it open? {s : s/2 ∈ −ℕ} = 2·(−ℕ) as a set of ℂ points: {−2m : m ∈ ℕ} — discrete: its complement is open: the set {s : ∃ m, s/2 = −m} is closed (discrete set of points — closed because it has no limit point: `Set.isClosed_of_discrete`? or via: the set is locally finite... There might be a slicker path: I only need differentiability in a NEIGHBORHOOD of s₀: take the ball B := ball s₀ (1/8): for s ∈ B: s/2 ∈ ball(s₀/2, 1/16): s₀/2 = −R/2 with dist(R/2,ℤ) ≥ 1/4: for s/2 = −m: |R/2 − m| < 1/16 + |s₀/2 − ... hmm: s/2 = −m ⟹ m = −s/2: |R/2 − m| = |R/2 + s/2| hmm: |s₀/2 − s/2| < 1/16 ⟹ |R/2 − m| ≤ |s₀/2 − s/2| + ... s₀/2 = −R/2: R/2 − m = −(s₀/2) − m = −(s₀/2 + m) = −(s₀/2 − s/2 + s/2 + m) = −(s₀/2 − s/2) − (s/2 + m) = −(s₀/2 − s/2) (since s/2 = −m): |R/2 − m| = |s₀/2 − s/2| < 1/16 < 1/4 — CONTRADICTION with hgapInt (m : ℤ) — wait m : ℕ, hgapInt (m : ℤ): |R/2 − (m:ℝ)| ≥ 1/4 ✓ contradiction. So on ball s₀ (1/8), Gammaℝ = π^{−s/2}Γ(s/2) with Γ(s/2) differentiable (s/2 avoids −ℕ ✓): differentiable ON the ball ⟹ analytic ON the ball (DifferentiableOn.analyticOn isOpen_ball) ⟹ AnalyticAt at s₀ (analyticOnNhd: AnalyticOn ball → AnalyticOnNhd at interior points — AnalyticOn is the on-Nhd version in current Mathlib?? The API: `DifferentiableOn.analyticOn : DifferentiableOn ℂ f s → IsOpen s → AnalyticOn ℂ f s` — AnalyticOn in current Mathlib means analytic on nhds of each point? (AnalyticOn got renamed: AnalyticOnNhd vs AnalyticOn — in recent Mathlib, AnalyticOnNhd s = ∀ x ∈ s, AnalyticAt, and AnalyticOn s = AnalyticOnNhd on the set... ugh naming. There's `DifferentiableOn.analyticOnNhd`? Let me just grep for the exact name when I get there.) Then logDeriv ΓR continuous at s₀: analyticAt_f.deriv.div analyticAt_f hnonzero → analyticAt → continuousAt ✓. And digamma continuous at s₀/2: analyticAt_digamma (LiFEntire, needs ∀ m, s₀/2 ≠ −(m:ℂ) ✓ from the dist argument) ✓. OK. So the im = 0 extension of (G) at s₀ (with pole-avoidance): ``` theorem logDeriv_Gammaℝ_eq_of_im_eq_zero {s₀ : ℂ} (hpoles : ∀ m : ℕ, s₀ / 2 ≠ -(m : ℂ)) : logDeriv Complex.Gammaℝ s₀ = -(Real.log Real.pi : ℂ) / 2 + (1 / 2 : ℂ) * Complex.digamma (s₀ / 2) := by -- both sides continuous at s₀; equal on the dense set {im ≠ 0} -- via tendsto uniqueness on 𝓝[≠] s₀ ``` Continuity of the pieces: - hGcont : ContinuousAt (logDeriv Complex.Gammaℝ) s₀: from analyticAt on the ball (as above) — needs the dist-to-poles at s₀/2, which I have as hpoles — but the ball argument needs a QUANTITATIVE distance: dist(s₀/2, −ℕ) > 0: from hpoles (∀ m, s₀/2 ≠ −m): the set −ℕ is closed discrete ⟹ positive distance... For s₀ = −R I have dist(R/2,ℤ) ≥ 1/4 — quantitative ✓. But the lemma as stated (hpoles only) doesn't give a quantitative distance — the ball-radius existence: {s₀/2}ᶜ ... −ℕ ∪ ... the set P := {s : ∃ m, s/2 = −(m:ℂ)} = (2·−ℕ): closed: its complement open: s₀ ∈ complement ⟹ ball. Closedness of (2·−ℕ) as a subset of ℂ: the image of −ℕ under ×2 — −ℕ ⊆ ℂ is closed (integers are closed: isClosed_intCast hmm: Set of negative integers: `Set.isClosed_intCast`? or (Set.range fun m : ℕ => −(m:ℂ)): closed via `Set.Finite.isClosed`? not finite. `isClosed_of_locallyFinite`? There IS a clean way: integers in ℂ form a closed set (Complex.isClosed_intCast? `Int.cast` closed: `isClosed_intCast` hmm — there's `Complex.isClosed_intCast`? or `Set.isClosed_range_intCast`?). This is getting heavy. ALTERNATIVE: the quantitative hypothesis: state the lemma with (hdist : ∃ c > 0, ∀ m : ℕ, c ≤ ‖s₀/2 + (m:ℂ)‖) — I HAVE that for s₀ = −R (c = 1/4-ish from hgapInt: ‖s₀/2 + m‖ = |R/2 − m|·... s₀ = −R: s₀/2 + m = m − R/2: ‖·‖ = |m − R/2| = |R/2 − m| ≥ 1/4 ✓ — well ‖(m:ℂ) − R/2·ofReal‖: m − R/2 as complex: norm = |m − R/2| ✓). So c = 1/4 works for s₀ = −R directly, no ℤ-clearance halving needed for the POLE distance (only for the (A)-application with the moving re(s/2)). So state: `logDeriv_Gammaℝ_eq_of_forall_dist {s₀ : ℂ} {c : ℝ} (hc : 0 < c) (hdist : ∀ m : ℕ, c ≤ ‖s₀ / 2 + (m : ℂ)‖) : ...`. Then ball(s₀, c): for s ∈ ball: s/2 + m: ‖s₀/2 − s/2‖ < c/2... wait: if s/2 = −m: ‖s₀/2 + m‖ = ‖s₀/2 − s/2‖ = ‖s₀ − s‖/2 < c/2 < c — contradiction with hdist. So ball(s₀, 2c)-ish avoids poles: take ball(s₀, 2c): ‖s₀ − s‖ < 2c ⟹ ‖s₀/2 − s/2‖ < c ⟹ s/2 ≠ −m ∀m (else ‖s₀/2 + m‖ < c ✗). So Gammaℝ differentiable on ball(s₀, 2c) ⟹ analytic on it ⟹ analyticAt at s₀. And digamma at s₀/2: analyticAt_digamma (hpoles from hdist: ∀ m, s₀/2 ≠ −(m:ℂ): from c ≤ ‖s₀/2 + m‖: if = −m: norm 0 < c ✗) ✓ continuous. The dense-equality: on {im ≠ 0}: (G) applies (needs s.im ≠ 0 only — logDeriv_Gammaℝ_eq's sole hypothesis ✓). So f =ᶠ[𝓝[≠] s₀] g: the set {s | s.im ≠ 0} ∈ 𝓝[≠] s₀: via: {s | s.im = 0}ᶜ: the real-line complement: dense open: membership in 𝓝[≠] s₀: `mem_nhdsWithin_of_mem_nhds`? no — 𝓝[≠] s₀ membership: s ∈ 𝓝[≠] s₀ ↔ s ∪ {s₀} ∈ 𝓝 s₀ (nhdsWithin_union_singleton?). {im ≠ 0} ∪ {s₀}: open? complement is {im = 0} ∖ {s₀} = the real line minus s₀ — closed? Hmm: {im = 0} is closed (preimage of {0} under continuous im); removing a point keeps it... {im = 0} ∖ {s₀}: closed iff... real line minus a point IS closed in ℂ (its complement {im ≠ 0} ∪ {s₀} is open? at s₀: any ball around s₀ contains im ≠ 0 points ✓ contained in the set {im≠0}∪{s₀} ✓ so s₀ is interior ✓; other points obviously interior ✓). So {im ≠ 0} ∪ {s₀} is open ∋ s₀ ⟹ ∈ 𝓝 s₀ ⟹ {im ≠ 0} ∈ 𝓝[≠] s₀ (`nhdsWithin_mem_iff`? the exact lemma: `mem_nhdsWithin_compl_iff` or `nhdsWithin_compl`... There's: `mem_nhdsWithin_iff_eventually`? Simplest: show {im ≠ 0} ∈ 𝓝[≠] s₀ via `mem_nhdsWithin_of_mem_nhds`?? no. Via the definition: 𝓝[≠] s₀ = 𝓝 s₀ ⊓ 𝓟 ({s₀}ᶜ): membership: A ∈ 𝓝[≠] s₀ iff ∃ U ∈ 𝓝 s₀, U ∩ ({s₀}ᶜ) ⊆ A: take U := {im ≠ 0} ∪ {s₀} (∈ 𝓝 s₀ as open ∋ s₀): U ∖ {s₀} = {im ≠ 0} ∩ ... ⊆ A ✓. Lemma: `mem_nhdsWithin_iff_exists_mem_nhds_inter` — used in LiDigamma:654 above ✓ same pattern.) Then: f s₀ = g s₀: tendsto_nhds_unique: both ContinuousAt: Tendsto f (𝓝[≠] s₀) (𝓝 (f s₀)) := hGcont.tendsto_nhdsWithin... (ContinuousAt → Tendsto on nhdsWithin: `(ContinuousAt.tendsto_nhdsWithin)`? or hcont.continuousWithinAt.tendsto: ContinuousAt.continuousWithinAt : ContinuousWithinAt f s s₀: ContinuousWithinAt.tendsto : Tendsto f (𝓝[s] f s₀) hmm: ContinuousWithinAt f u s₀ := Tendsto f (𝓝[u] s₀) (𝓝 (f s₀)) ✓. So hGcont.continuousWithinAt (u := {s₀}ᶜ). With the EventuallyEq f =ᶠ[𝓝[≠] s₀] g ⟹ Tendsto f (𝓝[≠] s₀) (𝓝 (f s₀)) ∧ Tendsto g (𝓝[≠] s₀) (𝓝 (g s₀)) ⟹ f s₀ = g s₀ (tendsto_nhds_unique (neBot)). `Filter.EventuallyEq.tendsto_iff`? or `tendsto_congr'`: Tendsto.congr' (h : f₁ =ᶠ[l] f₂) : Tendsto f₁ l a ↔ Tendsto f₂ l a ✓. Then tendsto_nhds_unique hnebot (h1.congr' heq) h2 — hmm tendsto_nhds_unique (hl : NeBot l) (h1 : Tendsto f l (𝓝 a)) (h2 : Tendsto f l (𝓝 b)) : a = b ✓. OK — this is all doable but it's ~80-100 lines for the extension. Hmm. Let me reconsider ONE more time whether I can avoid (G) at s = −R entirely. The ONLY place (G) at a real point is needed: case (iii)'s bracket at s = −R. The bracket: logDeriv ΓR(−R) + logDeriv ΓR(1+R). For the FE identity (logDeriv_zeta_fe) at s = −R I need differentiableAt Gammaℝ at −R and 1+R (fine via the new differentiableAt_Gammaℝ_of... hmm — wait, actually — I need AnalyticAt for the logDeriv continuity... no: logDeriv_zeta_fe's hypotheses are (hd : DifferentiableAt ℂ Complex.Gammaℝ s) — just differentiable! My new `differentiableAt_Gammaℝ_of_not_neg_nat` (cloned from the im≠0 proof with hhalf from hdist) discharges those at −R and 1+R ✓. So the remaining need: EVALUATE/BOUND ‖logDeriv ΓR(−R) + logDeriv ΓR(1+R)‖. What if I bound it via the m-shift recurrence instead of (G)? 5d's `logDeriv_Gammaℝ_shift` — what does it say exactly? From STATE session 025: "the ΓR +4 shift logDeriv_Gammaℝ_shift (Gammaℝ_def + Gamma_add_one twice + exp-form cpow arithmetic) putting both digamma arguments in re > 0". Its statement: probably logDeriv ΓR s = logDeriv ΓR (s+4) − (digamma-shift terms)... and then the bracket bound in 5d used StirlingVert's digamma_stirling on the SHIFTED arguments. For s = −R: logDeriv ΓR(−R) = logDeriv ΓR(4−R) − T(s): still needs evaluating logDeriv ΓR at the real point 4−R. Same issue one level down. The 5e-ii (G) proof itself: `logDeriv_Gammaℝ_eq` via "the m-fold shift + 5d's EventuallyEq machinery" — the proof shifts s by 2m to re > 0 and computes logDeriv via Gammaℝ_def directly at the SHIFTED point: logDeriv ΓR(s+2m) = −(logπ)/2 + ½ψ((s+2m)/2) — evaluating at s+2m with re(s+2m)/2 > 0: how does THAT evaluation avoid (G)-circularity? It uses Gammaℝ_def + Complex.logDeriv... at a point with s/2 having re > 0: Γ(s/2) differentiable + the digamma definition (logDeriv Γ = digamma by definition? Complex.digamma IS defined as deriv Γ / Γ = logDeriv Γ ✓ by definition: `Complex.digamma_def : digamma = logDeriv Gamma`? or digamma s := deriv Gamma s / Gamma s — there must be a def lemma). So at s₀ = −R: logDeriv ΓR(−R) = −(logπ)/2 + ½·(logDeriv Γ)(−R/2)·... = −(logπ)/2 + ½ψ(−R/2) — the direct computation via Gammaℝ_def: logDeriv ΓR s₀ = logDeriv (fun s => π^{−s/2}·Γ(s/2)) s₀ = deriv(π^{−s/2}Γ(s/2))/（π^{−s₀/2}Γ(s₀/2)) — computable: deriv of the product at s₀: (π^{−s/2})' = −(logπ)/2·π^{−s/2}; (Γ(s/2))' = ½·digamma(s/2)·Γ(s/2) (via deriv.comp + the digamma def). So: logDeriv ΓR s₀ = [−(logπ)/2·π^{−s₀/2}·Γ(s₀/2) + π^{−s₀/2}·½·digamma(s₀/2)·Γ(s₀/2)] / (π^{−s₀/2}Γ(s₀/2)) = −(logπ)/2 + ½ψ(s₀/2). That's a DIRECT ~40-line computation with NO continuity argument! Needs: - DifferentiableAt (fun s => (π:ℂ)^(−s/2)) s₀ ✓ (as in the im≠0 proof). - DifferentiableAt (fun s => Γ(s/2)) s₀: (Complex.differentiableAt_Gamma _ hhalf).comp ✓ (hhalf from hdist). - The derivative values: HasDerivAt (π^{−s/2}) (−(logπ)/2·π^{−s₀/2}) s₀: const_cpow hasDerivAt: `HasDerivAt.const_cpow`? and HasDerivAt (Γ(s/2)) (digamma(s₀/2)·Γ(s₀/2)·(1/2)): deriv Γ(s/2) = (deriv Γ)(s₀/2)·(1/2) = digamma(s₀/2)·Γ(s₀/2)·½ — via Complex.deriv_Gamma?? hmm: deriv Γ = digamma·Γ: `Complex.deriv_Gamma`? there should be `Complex.deriv_Gamma : deriv Gamma s = digamma s * Gamma s`?? Hmm — digamma is DEFINED as logDeriv Gamma (logDeriv Γ s = deriv Γ s / Γ s) so deriv Γ s = digamma s · Γ s — from the definition + Γ(s) ≠ 0: `Complex.digamma_def`? Let me check Complex.digamma's definition in Mathlib. Actually — logDeriv f s = deriv f s / f s BY DEFINITION (logDeriv_def). And Complex.digamma s := logDeriv Complex.Gamma s (I believe digamma is DEFINED as logDeriv Gamma in Mathlib — `Complex.digamma : ℂ → ℂ := fun s => logDeriv Gamma s`? or via the Weierstrass form... In Mathlib: `Complex.digamma (s : ℂ) : ℂ := deriv Gamma s / Gamma s`?? Let me grep.) Then logDeriv ΓR s₀ computation: ``` have hdef : Complex.Gammaℝ = fun z : ℂ => (Real.pi : ℂ) ^ (-z / 2) * Complex.Gamma (z / 2) := funext Complex.Gammaℝ_def rw [hdef] rw [logDeriv_apply, ((h1.hasDerivAt).mul (h2.hasDerivAt)).deriv] -- deriv of product -- then field_simp with the nonvanishing: π^{−s₀/2}·Γ(s₀/2) ≠ 0 ``` Hmm — the deriv of the product: (f·g)' = f'·g + f·g' (HasDerivAt.mul.deriv? `HasDerivAt.mul (hf : HasDerivAt f f' x) (hg : HasDerivAt g g' x) : HasDerivAt (f·g) (f'·g x + f x·g') x` — .deriv gives the deriv form ✓). And the pieces: f := fun z => (π:ℂ)^(−z/2): f' : HasDerivAt f (−(log π)/2·π^{−s₀/2}·(1/2)?? — const_cpow: d/dz π^{−z/2} = π^{−z/2}·log π·(−1/2): HasDerivAt.const_cpow (hf : HasDerivAt f f' x) (h : ...) : HasDerivAt (fun x => c^(f x)) (c^(f x)·log c·f') x — the Mathlib form: `HasDerivAt.const_cpow (hf : HasDerivAt f f' x) (hc : c ≠ 0 ∨ ...)`: in Mathlib: `HasDerivAt.const_cpow (hf : HasDerivAt f f' x) (h : a ≠ 0 ∨ f x ≠ 0) : HasDerivAt (fun x => a ^ f x) (a ^ f x * (Complex.log a * f')) x`? something like that. Used in 5d's gammaR_shift_four proof region — there are cpow computations in LiReflect already. And g := fun z => Γ(z/2): HasDerivAt Γ(z/2) (digamma(s₀/2)·Γ(s₀/2)·(1/2)): HasDerivAt.comp: (hasDerivAt_Gamma?). Is there `Complex.hasDerivAt_Gamma (s) (hs) : HasDerivAt Gamma (digamma s * Gamma s) s`?? digamma is DEFINED as deriv Γ/Γ so deriv Γ s = digamma s·Γ s — if digamma is defined as the logDeriv: `Complex.digamma_def : digamma = logDeriv Gamma`? hmm. Let me grep Complex.digamma's definition.
Check how `Complex.digamma` is defined in this Mathlib (logDeriv of Gamma?) and the cpow/Gamma deriv API.

So the direct computation of (G) at s₀: ``` logDeriv Gammaℝ s₀ = deriv (fun z => π^(−z/2) * Γ(z/2)) s₀ / (π^(−s₀/2) * Γ(s₀/2)) ``` via logDeriv_apply + Gammaℝ_def. The deriv of the product via HasDerivAt.mul. This is ~50 lines. Same cost as the continuity route but more elementary. Actually — WAIT: logDeriv (f·g) = logDeriv f + logDeriv g when f,g differentiable and nonzero at the point (`logDeriv_mul (hf : f x ≠ 0) (hg : g x ≠ 0) (hf' : DifferentiableAt f x) (hg' : DifferentiableAt g x)`? — there's `logDeriv_mul` in Mathlib ✓ I'm fairly sure: `logDeriv_mul (hx : f x ≠ 0) (hy : g x ≠ 0) : logDeriv (f * g) x = logDeriv f x + logDeriv g x` — needs differentiability hypotheses: (hf : DifferentiableAt 𝕜 f x)? The exact signature: `theorem logDeriv_mul {f g : 𝕜 → 𝕜} {x : 𝕜} (hx : f x ≠ 0) (hy : g x ≠ 0) (hf : DifferentiableAt 𝕜 f x) (hg : DifferentiableAt 𝕜 g x) : logDeriv (f * g) x = logDeriv f x + logDeriv g x` ✓. Then: - logDeriv (fun z => (π:ℂ)^(−z/2)) s₀ = Complex.log π · (−1/2) = −(log π)/2: logDeriv of a^f = log a · f' when a ≠ 0... via logDeriv_apply + deriv: deriv (π^{−z/2}) at s₀ = π^{−s₀/2}·(Complex.log π·(−1/2)): and divided by π^{−s₀/2} ≠ 0: = Complex.log π·(−1/2). The ofReal_log: Complex.log (π:ℂ) = (Real.log π:ℂ) ✓ (Complex.ofReal_log pi_nonneg). - logDeriv (fun z => Γ(z/2)) s₀ = (digamma(s₀/2)·Γ(s₀/2)·(1/2)) / Γ(s₀/2) = digamma(s₀/2)/2 — via the chain rule: deriv (Γ∘(·/2)) s₀ = deriv Γ (s₀/2)·(1/2) = digamma(s₀/2)·Γ(s₀/2)·(1/2): deriv Γ (s₀/2) = digamma(s₀/2)·Γ(s₀/2): from digamma_def + logDeriv_apply: deriv Gamma w = digamma w · Gamma w: rw [digamma_def, logDeriv_apply]: deriv Γ w / Γ w — so deriv Γ w = (digamma w)·Γ w iff Γ w ≠ 0 ✓ (mul_div_cancel). So the direct (G)-at-real-point proof: ``` theorem logDeriv_Gammaℝ_eq_of_not_neg_nat {s₀ : ℂ} (hpoles : ∀ m : ℕ, s₀ / 2 ≠ -(m : ℂ)) : logDeriv Complex.Gammaℝ s₀ = -(Real.log Real.pi : ℂ) / 2 + (1 / 2 : ℂ) * Complex.digamma (s₀ / 2) := by have hdef : Complex.Gammaℝ = fun z : ℂ => (Real.pi : ℂ) ^ (-z / 2) * Complex.Gamma (z / 2) := funext Complex.Gammaℝ_def rw [hdef] -- the two factors: differentiability + nonvanishing have h1 : DifferentiableAt ℂ (fun z : ℂ => (Real.pi : ℂ) ^ (-z / 2)) s₀ := ... have h2 : DifferentiableAt ℂ (fun z : ℂ => Complex.Gamma (z / 2)) s₀ := ... have hne1 : (Real.pi : ℂ) ^ (-s₀ / 2) ≠ 0 := cpow_ne_zero _ (by exact_mod_cast Real.pi_ne_zero) have hne2 : Complex.Gamma (s₀ / 2) ≠ 0 := Complex.Gamma_ne_zero hpoles -- Gamma_ne_zero (hs : ∀ m, s ≠ -m) : Gamma s ≠ 0 ✓ (from Beta.lean:514 usage) rw [logDeriv_mul hne1 hne2 h1 h2] -- factor 1: logDeriv (π^(−z/2)) = −(logπ)/2 have hf1 : logDeriv (fun z : ℂ => (Real.pi : ℂ) ^ (-z / 2)) s₀ = -(Real.log Real.pi : ℂ) / 2 := ... -- factor 2: logDeriv (Γ(z/2)) = ½ψ(s₀/2) have hf2 : logDeriv (fun z : ℂ => Complex.Gamma (z / 2)) s₀ = (1 / 2 : ℂ) * Complex.digamma (s₀ / 2) := ... rw [hf1, hf2] ``` hf1: logDeriv_apply + deriv: deriv (π^{−z/2}) s₀: HasDerivAt: `HasDerivAt.const_cpow`: let me get the exact form. In Mathlib: `theorem HasDerivAt.const_cpow {f : ℂ → ℂ} {x : ℂ} {f' : ℂ} (hf : HasDerivAt f f' x) (h : c ≠ 0 ∨ f x ≠ 0) : HasDerivAt (fun x => c ^ f x) (c ^ f x * Complex.log c * f') x`? I think the RHS is (c ^ f x * (Complex.log c * f')). Then .deriv: deriv = that. Then logDeriv_apply: deriv/value = [π^{−s₀/2}·log π·(−1/2)]/π^{−s₀/2} = log π·(−1/2) (mul_div_cancel_left₀ hne1) = −(log π)/2·... Complex.log (π:ℂ) = (Real.log π:ℂ) (Complex.ofReal_log Real.pi_nonneg) and the form: −(Real.log π:ℂ)/2 — matches after push_cast/ring. hf2: logDeriv_apply + deriv (Γ(z/2)) s₀ = (1/2)·deriv Γ (s₀/2): HasDerivAt.comp: `((Complex.differentiableAt_Gamma _ hpoles).hasDerivAt).comp s₀ (hasDerivAt for z/2)`: HasDerivAt (z/2) (1/2): `hasDerivAt_id' s₀ |>.div_const 2`?? or (hasDerivAt_id s₀).div_const 2. Then HasDerivAt.comp x hg hf: HasDerivAt (Γ∘(·/2)) (deriv Γ (s₀/2)·(1/2)) — the chain rule form: (hg.comp x hf): HasDerivAt (fun x => Γ (x/2)) ((deriv Γ (s₀/2)) * (1/2)) x. .deriv: deriv (fun z => Γ (z/2)) s₀ = deriv Γ (s₀/2)·(1/2) — wait the comp gives HasDerivAt (fun x => g (f x)) (g' * f') where g' = deriv g (f x) — via HasDerivAt.deriv: deriv (g∘f) x = g' * f' ✓. Then: logDeriv (Γ∘(·/2)) s₀ = [deriv Γ (s₀/2)·(1/2)] / Γ(s₀/2) = (1/2)·[deriv Γ (s₀/2)/Γ(s₀/2)] = (1/2)·digamma(s₀/2) (digamma_def + logDeriv_apply reversed). deriv Γ (s₀/2) — the HasDerivAt from differentiableAt_Gamma: ((Complex.differentiableAt_Gamma _ hpoles).hasDerivAt) : HasDerivAt Gamma (deriv Gamma (s₀/2)) (s₀/2) ✓. OK — this is clean, ~60 lines, no topology. And it SUPERSEDES the im ≠ 0 case: works at ANY s₀ with s₀/2 off the poles — including im ≠ 0 points! So I could use it everywhere in case (iii) — but (G) already exists for im ≠ 0, so use (G) there and this new lemma only at s₀ = −R... Actually — hmm, since it works at im ≠ 0 too (s/2 with im ≠ 0 ⟹ off poles ✓), ONE lemma `logDeriv_Gammaℝ_eq_of_not_neg_nat` handles ALL of case (iii) uniformly! (For s with im s ≠ 0: s/2 has im ≠ 0 ⟹ hpoles ✓.) Let me just prove the one lemma and use it everywhere in case (iii). No continuity needed at all!! WAIT — but why did 5e-ii bother with the m-shift + im ≠ 0 restriction then? Probably because the direct logDeriv_mul route has a subtlety... hmm: logDeriv_mul needs DifferentiableAt of both factors at s₀ — the cpow factor: DifferentiableAt (fun z => (π:ℂ)^(−z/2)) s₀ — via DifferentiableAt.const_cpow (differentiableAt_id.neg.div_const 2) (Or.inl pi_ne_zero) ✓ fine. And Γ(z/2) ✓. So the direct proof works generally — 5e-ii's (G) via the shift was just the route they took (maybe logDeriv_mul wasn't noticed or cpow-defeq issues). Let me just write the direct proof. One concern: logDeriv_mul's exact name/signature in this Mathlib. Let me grep.
`digamma := logDeriv Gamma` by definition — so (G) at real non-pole points is a direct `logDeriv_mul` computation, no continuity needed. Verify `logDeriv_mul`'s signature.

`HasDerivAt.const_cpow (hf) (h0) : HasDerivAt (fun x => c ^ f x) (c ^ f x * Complex.log c * f') x`. Now I have everything for 5e-v-c. Let me set up the build plan with sub-stages: **c-i: the (G)-at-real-point + gapCircle_sep + nearZeros count.** 1. `differentiableAt_Gammaℝ_of_not_neg_nat {s : ℂ} (hs : ∀ m : ℕ, s / 2 ≠ -(m : ℂ)) : DifferentiableAt ℂ Complex.Gammaℝ s` — clone of the im≠0 proof. 2. `logDeriv_Gammaℝ_eq_of_not_neg_nat {s₀ : ℂ} (hs : ∀ m : ℕ, s₀ / 2 ≠ -(m : ℂ)) : logDeriv Gammaℝ s₀ = −(log π:ℂ)/2 + (1/2:ℂ)·digamma (s₀/2)` — via logDeriv_mul. 3. `gapCircle_sep` — the standalone separation 1/(32Ĉ₀) ≤ ‖s−ρ‖ for nontrivial ρ with ‖ρ‖ ∈ (R−2, R+2) (clone of shell_crit's hsep, ρ : ℂ). 4. `nearZeros_count_le {t : ℝ} (ht : 10 ≤ |t|) : ∑ ρ ∈ nearZeros t, (zeroMult ρ : ℝ) ≤ 3·A0count·Real.log (3·max |t−1| |t+1| + 5)` — zerosIn(t−1, t+1] cover + Ncount_le_of_interval_gen. 5. `nearZeros_term_le` — per-ρ separation: for ρ ∈ nearZeros (s.im): 1/(32Ĉ₀) ≤ ‖s−ρ‖ (the ‖ρ‖ > R−2 vs ≤ R−2 split + gapCircle_sep). **c-ii: digamma bounds.** 6. `digamma_right_le {w} (hwre : 1.75 ≤ w.re) : ‖digamma w‖ ≤ 48 + 23·log(2+‖w‖)`. 7. `digamma_circle_le {s} (hs : ‖s‖ = R) (hgapInt) (hR : 16002 ≤ R) : ‖digamma (s/2)‖ ≤ 62 + 23·log (2 + R/2)`. 8. Small elems: `norm_one_div_circle_le`, `log_pi_div_two_le`. **c-iii: logDeriv_circle_le + Fexpr_circle_le.** 9. `logDeriv_circle_le` — the three regions. Includes: the near-sum bound (via nearZeros count + separation), the FE route for re < −5/2 (logDeriv_zeta_fe at all points — hypotheses discharged: s ≠ 0 (‖s‖=R>0), s ≠ 1 (re < −5/2), Gammaℝ s ≠ 0 (Gammaℝ_eq_zero_iff + pole avoidance: s/2 ∉ −ℕ — for im s ≠ 0: im(s/2) ≠ 0 ✓; for s = −R: dist(R/2,ℤ) ≥ 1/4 ✓ hgapInt), ζ s ≠ 0 (zeta_zero_classification + s ≠ −2n: s/2 ∉ −ℕ ⟹ s ≠ −2n ✓ same; s ≠ 0 ✓; not nontrivial: re < −5/2 vs (0,1) ✓), DifferentiableAt Gammaℝ s (via #1 with s/2 ∉ −ℕ ✓), and at 1−s: 1−s ≠ 0 ✓ (s≠1), 1−s ≠ 1 ✓ (s≠0), Gammaℝ(1−s) ≠ 0 ((1−s)/2 ∉ −ℕ: re((1−s)/2) > 0 ✓), ζ(1−s) ≠ 0 (re(1−s) > 1: Mathlib's riemannZeta_ne_zero_of_one_le_re? — check the name; used in 5c/5d — grep), DifferentiableAt ✓ ((1−s)/2 ∉ −ℕ ✓). 10. `Fexpr_circle_le` — the assembly. Let me also check Gammaℝ_eq_zero_iff and the zeta nonvanishing names quickly.
All API pinned. Check the zero-vanishing facts needed for the FE route (`Gammaℝ_eq_zero_iff`, `Gamma_ne_zero`, zeta nonvanishing re ≥ 1).

All present: - `Complex.Gammaℝ_eq_zero_iff : Gammaℝ s = 0 ↔ ∃ m : ℕ, s = -2 * (m : ℂ)` (used with rw at LiContour:492). - `Complex.Gamma_ne_zero (h : ∀ m : ℕ, s ≠ -(m : ℂ)) : Gamma s ≠ 0`. - `riemannZeta_ne_zero_of_one_le_re : 1 ≤ s.re → s ≠ 1 → riemannZeta s ≠ 0` (from LiDisc:73 usage: `riemannZeta_ne_zero_of_one_le_re h h2`). - `zeta_zero_classification {s} (hs : riemannZeta s = 0) : IsNontrivialZero s ∨ s = 0 ∨ ∃ n : ℕ, 1 ≤ n ∧ s = -2 * (n : ℂ)`. Now let me set up the todo list and start building c-i. I'll write §10 in LiCircleBound.lean. First block (c-i): 1. `differentiableAt_Gammaℝ_of_not_neg_nat`. 2. `logDeriv_Gammaℝ_eq_of_not_neg_nat`. 3. `gapCircle_sep` (standalone separation for ρ : ℂ). 4. `nearZeros_count_le`. 5. `gapCircle_sep_near` (the separation for ρ ∈ nearZeros (s.im) — any ‖ρ‖). For #3 (gapCircle_sep): the shell_crit hsep proof but for ρ : ℂ with IsNontrivialZero ρ. The proof used hgap on ρ or conj ρ (both ℂ-valued, fine), the arc analysis with t := s.im, γ := ρ.im. It also used ρ.re ∈ (0,1) (|re ρ| ≤ 1) for the near-axis case. Signature: ``` theorem gapCircle_sep {k : ℕ} (hk : 4000 ≤ k) {R : ℝ} (hRlo : 4 * (k : ℝ) + 5 / 2 ≤ R) (hgap : ∀ ρ : ℂ, IsNontrivialZero ρ → 1 / (16 * C0hat (4 * (k : ℝ) + 9 / 2)) ≤ |ρ.im - R| ∨ 1 ≤ |ρ.im - R|) {s : ℂ} (hs : ‖s‖ = R) {ρ : ℂ} (hρ : IsNontrivialZero ρ) (hρnorm : R - 2 < ‖ρ‖) : 1 / (32 * C0hat (4 * (k : ℝ) + 9 / 2)) ≤ ‖s - ρ‖ ``` Note: only need ‖ρ‖ > R−2 (the term bound used ‖ρ‖ > R−2 for the denominator, but the SEPARATION itself didn't use the shell range except... let me recheck hsep's proof: the strip-arc case: |t−γ| ≥ ||γ|−R| − 13/R — the hγR used hgap (any nontrivial zero) ✓ no norm range. The near-axis case: |s.re|−1 with |ρ.re| ≤ 1 ✓ no norm range. So the separation holds for ALL nontrivial ρ — no ‖ρ‖ range needed at all!! Interesting — so gapCircle_sep can drop hρnorm entirely. (In shell_crit the range was for the TERM bound, not the separation.) But careful — in shell_crit's hsep, hρRm2'/hρRp2 were obtained but... scanning my proof: hsep's strip case used only hgap + the arc bounds ✓; the near-axis case used hreρ : |ρ.re| ≤ 1 ✓. So no norm range — drop it. 5. `gapCircle_sep_near`: for ρ ∈ nearZeros (s.im) with the gap circle: 1/(32Ĉ₀) ≤ ‖s−ρ‖: ``` theorem gapCircle_sep_of_mem_nearZeros {k} (hk) {R} (hRlo) (hgap) {s : ℂ} (hs : ‖s‖ = R) {ρ : ℂ} (hρ : ρ ∈ nearZeros (s.im)) : 1 / (32 * C0hat (4 * (k : ℝ) + 9 / 2)) ≤ ‖s - ρ‖ := by -- ρ nontrivial from zeroDisc_isNontrivial by_cases hn : R - 2 < ‖ρ‖ · exact gapCircle_sep hk hRlo hgap hs (nontrivial) · -- ‖ρ‖ ≤ R−2: ‖s−ρ‖ ≥ R−‖ρ‖ ≥ 2 ≥ 1/(32Ĉ₀) push Not at hn have h1 : (2:ℝ) ≤ ‖s - ρ‖ := by have h2 := abs_norm_sub_norm_le s ρ rw [hs, abs_of_nonneg (by linarith [hn, hRlo...] : 0 ≤ R − ‖ρ‖)] at h2 linarith [h2, hn] have h3 : 1/(32*Ĉ₀) ≤ 2 := by (Ĉ₀ ≥ 2) exact h3.trans h1 ``` zeroDisc_isNontrivial — need the exact signature: from session 023/024: `zeroDisc_isNontrivial : ρ ∈ zeroDiscFinset t → IsNontrivialZero ρ`? Let me check. Also whether nearZeros membership gives it: nearZeros t := (zeroDiscFinset t).filter (· |im−t| < 1): mem_nearZeros gives ρ ∈ zeroDiscFinset t ∧ |ρ.im − t| < 1 ✓. 6. `nearZeros_count_le {t} (ht : 10 ≤ |t|) : ∑ ρ ∈ nearZeros t, (zeroMult ρ : ℝ) ≤ 3 * A0count * Real.log (3 * max |t-1| |t+1| + 5)`: ``` -- nearZeros t ⊆ (zerosIn (t−1) (t+1)).toFinset have hsub : nearZeros t ⊆ (Zeta23.zerosIn (t-1) (t+1)).toFinset := by intro ρ hρ rw [mem_nearZeros] at hρ obtain ⟨hρd, hρt⟩ := hρ rw [Set.Finite.mem_toFinset] refine ⟨zeroDisc_isNontrivial hρd, ?_, ?_⟩ · have h1 : t - 1 < ρ.im := by have := (abs_lt.mp hρt).1 -- −1 < ρ.im − t linarith exact h1 · have h2 : ρ.im ≤ t + 1 := by have := (abs_lt.mp hρt).2 -- ρ.im − t < 1 linarith exact h2 -- bridge to Ncount calc ∑ ρ ∈ nearZeros t, (zeroMult ρ : ℝ) ≤ ∑ ρ ∈ (zerosIn (t−1) (t+1)).toFinset, (zeroMult ρ : ℝ) := Finset.sum_le_sum_of_subset_of_nonneg hsub (fun z _ _ => Nat.cast_nonneg _) _ = (Zeta23.Ncount (t−1) (t+1) : ℝ) := by rw [Zeta23.Ncount, finsum_mem_eq_finite_toFinset_sum _ (Zeta23.zerosIn_finite _ _), Nat.cast_sum] _ ≤ A0count * 3 * Real.log (3 * max |t−1| |t+1| + 5) := by have h1 := Ncount_le_of_interval_gen (a := t−1) (b := t+1) (by linarith) have h2 : t + 1 - (t - 1) + 1 = 3 := by ring rw [h2] at h1 exact h1 _ = 3 * A0count * Real.log (3 * max |t−1| |t+1| + 5) := by ring ``` Hmm wait — zerosIn membership requires IsNontrivialZero ρ AND a < im ∧ im ≤ b — zerosIn's def: {ρ | IsNontrivialZero ρ ∧ a < im ∧ im ≤ b} ✓ refine ⟨nt, h1, h2⟩ — but is the finset's underlying set in that form? zerosIn_finite (a) (b) : (zerosIn a b).Finite: toFinset membership via Set.Finite.mem_toFinset ⟸ membership in the set ✓.

Check `zeroDisc_isNontrivial`'s exact signature, then start building c-i.

Several errors: 1. `cpow_ne_zero` unknown — the name is `Complex.cpow_ne_zero`? Since `open Complex` is active, `cpow_ne_zero` should resolve... it's not there. Check the name: maybe `Complex.cpow_ne_zero` doesn't exist; alternatives: `Complex.cpow_ne_zero_iff` or prove directly: (π:ℂ)^(−s₀/2) = exp(log π·(−s₀/2)) ≠ 0 (exp_ne_zero via cpow_def_of_ne_zero). Let me grep. 2. `logDeriv_mul` signature mismatch — I called `logDeriv_mul _ hne1 hne2 h1 h2` and Lean parsed `logDeriv_mul (-s₀/2) hne1 ?m h1` — the argument order: `logDeriv_mul {f g} (x : 𝕜) (hf : f x ≠ 0) (hg : g x ≠ 0) (hdf) (hdg)` — my `_` for x got unified with `−s₀/2`?? The error shows `logDeriv_mul (-s₀ / 2) hne1 ?m.226 h1` with h1 expected at the hdg slot of type `DifferentiableAt ℂ (HPow.hPow ↑Real.pi) (-s₀ / 2)` — that's `DifferentiableAt ℂ (fun z => c^z)?? no: (HPow.hPow ↑Real.pi) applied to (−s₀/2) — that's g x where g := HPow.hPow π as a function of z... The issue: my f,g are implicit and Lean couldn't infer them properly — f should be `fun z => (π:ℂ)^(-z/2)` and g := fun z => Gamma (z/2): the mismatch shows Lean took g := (HPow.hPow π) (the standalone power) — because h1's type mentions `↑Real.pi ^ (-z / 2)` — elaborator unified f z := π^(−z/2) with f := HPow.hPow π ∘ (−·/2)?? The hg slot expected `DifferentiableAt ℂ (HPow.hPow ↑Real.pi) (-s₀/2)` — wait that's `DifferentiableAt ℂ (HPow.hPow ↑Real.pi) (-s₀/2)` — DifferentiableAt of the FUNCTION (HPow.hPow π) at the POINT (−s₀/2) — so Lean unified g := HPow.hPow ↑Real.pi (the exponentiation function with base π) and the point as... this is the f/g implicit unification mess. Fix: pin f and g explicitly: `rw [logDeriv_mul (f := fun z : ℂ => (Real.pi : ℂ) ^ (-z / 2)) (g := fun z : ℂ => Complex.Gamma (z / 2)) _ hne1 hne2 h1 h2]` Wait — logDeriv_mul's statement: `logDeriv (fun z => f z * g z) x = logDeriv f x + logDeriv g x` — the LHS after my `rw [hdef]` is `logDeriv (fun z => ↑Real.pi ^ (-z / 2) * Gamma (z / 2)) s₀` — with f,g pinned the LHS unifies ✓. 3. `nearZeros`/`mem_nearZeros` unknown — they're in LiDisc.lean — is LiDisc imported? LiCircleBound imports NguyenRH1.LiFEntire, LiGapCircles, Zeta23.RvM.LocalCount. LiDisc is imported by... LiFEntire imports LiSides etc. Does anything import LiDisc/LiReflect? LiReflect imports LiDisc probably; LiFEntire might not reach them. Add `import NguyenRH1.LiDisc` (and LiReflect + LiDigammaLeft for later parts) to LiCircleBound's imports. Since those files root-import each other: LiReflect imports LiDisc (5d builds on 5c); LiDigammaLeft imports... 5e-ii. Let me just add all three: LiDisc, LiReflect, LiDigammaLeft. 4. The `⊢ logDeriv ... = ...` unsolved at 2906 — the rw [logDeriv_mul...] failed so the goal remained. Fixed by #2's pin.
Missing imports (nearZeros lives in LiDisc) + the `logDeriv_mul` f/g pinning + the cpow-nonzero name.

Several errors in hf1/hf2: 1. hf1's hder: the `convert h using 1 <;> ring` for hbase — the HasDerivAt for `fun z => -z/2` with derivative `-(1:ℂ)/2`: `(hasDerivAt_id' s₀).neg.div_const 2` — HasDerivAt (fun z => -z/2)? .neg gives HasDerivAt (fun z => -z) (−1); .div_const 2: HasDerivAt (fun z => (−z)/2) ((−1)/2) — the function is `fun z => -z / 2` — same as (−z)/2 ✓ but the DERIVATIVE: −1/2 vs my stated −(1:ℂ)/2 — defeq? −1/2 vs −(1/2): ring-equal ✓ the `convert h using 1 <;> ring` handles the mismatch... The error at 2930 (ring_nf no progress): the `convert h using 1` generated an equality goal that ring can't close — probably the derivative VALUES: −1/2 vs −(1:ℂ)/2 hmm. Actually simpler: state hbase's derivative as (−1)/2 hmm — or avoid: ``` have hbase : HasDerivAt (fun z : ℂ => -z / 2) (-(1 : ℂ) / 2) s₀ := by have h := (hasDerivAt_id' s₀).neg.div_const 2 -- h : HasDerivAt (fun x => -x / 2) (-1 / 2) s₀ convert h using 1 ``` with the value equality −(1:ℂ)/2 = −1/2 by `ring`?? The error says ring_nf made no progress — so the goal wasn't a ring identity — maybe convert produced a FUNCTION equality: `fun z => -z/2 = fun z => -z/2`? no. Hmm — maybe the h's function form: .div_const on HasDerivAt (fun z => -z): gives HasDerivAt (fun x => -x / 2)?? or (fun x => (-x) / 2)... same. And the value: -1/2 (a division of -1 by 2) vs -(1:ℂ)/2 — ring should prove −(1:ℂ)/2 = −1/2 ✓ it's a ring identity. The error at 2930:30 with TWO ring_nf failures — the `<;> ring` ran on two goals. Maybe convert produced `-(1:ℂ)/2 = -1/2` AND a function equality — the function equality `(fun z => -z / 2) = (fun x => -x / 2)`?? alpha-equiv — convert using 1 should close by rfl... Simplify drastically: state the whole hder via a cleaner route: use `HasDerivAt.const_cpow` directly on the identity-ish base: ``` have hbase : HasDerivAt (fun z : ℂ => -z / 2) (-(1 : ℂ) / 2) s₀ := (hasDerivAt_id' s₀).neg.div_const 2 ``` WITHOUT convert — just check what .neg.div_const 2 produces EXACTLY: (hasDerivAt_id' s₀) : HasDerivAt (fun x => x) (1) s₀; .neg : HasDerivAt (fun x => -x) (-1) s₀; .div_const 2 : HasDerivAt (fun x => -x / 2) (-1 / 2) s₀. So the derivative is −1/2 (as `-1 / 2`) NOT `-(1:ℂ)/2`. Are they the same TERM? −1/2 parses as HDiv.hDiv (−1) 2; −(1:ℂ)/2 = HDiv.hDiv (−(1:ℂ)) 2 — `−1` vs `−(1:ℂ)` — the −1 in −1/2 is also Neg.neg 1 with the OfNat — SAME term actually (both Neg.neg (OfNat.ofNat 1)). So they're identical?? Then hbase := that directly ✓ (the error suggests convert generated something ring couldn't handle — maybe convert itself failed and left ring-goals). Just drop the convert: `exact (hasDerivAt_id' s₀).neg.div_const 2`. 2. hf1's hder.const_cpow: `convert hbase.const_cpow ... using 1; ring` — const_cpow's conclusion: HasDerivAt (fun x => c ^ f x) (c ^ f x * Complex.log c * f') x — with f := fun z => −z/2, f' := −1/2: the value: π^(−s₀/2) * Complex.log π * (−1/2) — my stated hder has `(Real.pi : ℂ) ^ (-s₀ / 2) * Complex.log (Real.pi : ℂ) * (-(1 : ℂ) / 2)` — the f' = −1/2 vs −(1:ℂ)/2 — same as above ✓ so const_cpow gives EXACTLY the hder I stated (modulo the f' form) — so drop the convert and just use it directly, with my hder statement adjusted to the const_cpow output form `... * (-1 / 2)`. Simplest: make hder := hbase.const_cpow ... directly (no stated type — use `have hder := hbase.const_cpow (Or.inl ...)`) — then hder.deriv gives the deriv in whatever form. Then the goal after rw [hder.deriv]: `π^(−s₀/2) * log π * (−1/2) / π^(−s₀/2) = −(log π)/2` hmm — wait logDeriv_apply: logDeriv f s₀ = deriv f s₀ / f s₀: so the goal: π^(−s₀/2)*log π*(−1/2) / π^(−s₀/2) = −↑(Real.log π)/2: the `mul_div_assoc, div_self hne1, mul_one` chain: π^… * log π * (−1/2) / π^… — pattern for div_self: `π^(−s₀/2) / π^(−s₀/2)` — the error shows it didn't match because the form is `π^… * log π * (−1/2) / π^…` — parse: ((π^… * log π) * (−1/2)) / π^… — mul_div_assoc: a * b / c = a * (b / c): applied to (π^… * log π) * (−1/2) / π^…: gives π^… * log π * ((−1/2)/π^…)?? mul_div_assoc : a * b / c = a * (b / c) — with a := π^… * log π, b := −1/2, c := π^…: → π^… * log π * ((−1/2) / π^…) — NOT the div_self pattern. The error's goal: `↑Real.pi ^ (-s₀ / 2) * log ↑Real.pi * (-1 / 2 / ↑Real.pi ^ (-s₀ / 2)) = -↑(Real.log Real.pi) / 2` — exactly that wrong split. Fix: field_simp [hne1] then ring: ``` rw [hder.deriv] field_simp [hne1] rw [Complex.ofReal_log Real.pi_nonneg] push_cast ring ``` field_simp [hne1] clears the denominator: goal becomes π^… * log π * (−1/2) = −↑(Real.log π)/2 * π^…: then ofReal_log + push_cast + ring... the Complex.log π vs ↑(Real.log π): rw [Complex.ofReal_log Real.pi_nonneg] rewrites log ↑Real.pi → ↑(Real.log π) ✓ then `↑(Real.log π) * (−1/2) = −↑(Real.log π)/2` — hmm the LHS after field_simp: π^… * ↑(Real.log π) * (−1/2) = −↑(Real.log π)/2 * π^…: ring ✓ (with ofReal_log rewitten, all casts aligned by push_cast). Wait — ofReal_log: Complex.ofReal_log (hx : 0 ≤ x) : ↑(Real.log x) = Complex.log ↑x — so rw [Complex.ofReal_log Real.pi_nonneg] rewrites LHS-to-RHS: occurrences of ↑(Real.log Real.pi) become Complex.log ↑Real.pi. The goal has Complex.log ↑Real.pi (from hder) and ↑(Real.log Real.pi) (in the target −↑(Real.log Real.pi)/2): rw [← Complex.ofReal_log Real.pi_nonneg] rewrites Complex.log ↑π → ↑(Real.log π) ✓ (direction ←). Then push_cast + ring. 3. hf2's hder: `rw [h.deriv]` — h : HasDerivAt (Gamma ∘ fun x => x/2)?? the comp: `(differentiableAt_Gamma _ hs).hasDerivAt.comp s₀ (hasDerivAt_id' s₀ |>.div_const 2)` — HasDerivAt.comp (hg : HasDerivAt g g' (f x)) (hf : HasDerivAt f f' x) : HasDerivAt (g ∘ f) (g' * f') x — the composed function is `Gamma ∘ fun x => x / 2` — my goal mentions `deriv (fun z => Gamma (z / 2)) s₀` — NOT syntactically `Gamma ∘ (fun x => x/2)` — the rewrite failed since h.deriv is about `Gamma ∘ fun x => x/2`. Fix: change hf2's deriv-equality to use the ∘ form, or state h differently: HasDerivAt (fun z => Gamma (z/2)) — via `(hg).comp x hf` gives the ∘ form; to get the lambda form use `HasDerivAt.comp_of_eq`? or just: `((Complex.differentiableAt_Gamma _ hs).hasDerivAt).comp s₀ ...` produces HasDerivAt (Gamma ∘ fun x => x/2) — and deriv (Gamma ∘ ...) — then the subsequent rw [hder] needs the goal's `deriv (fun z => Gamma (z / 2)) s₀` to match. Are `Gamma ∘ fun x => x / 2` and `fun z => Gamma (z / 2)` defeq? Yes (eta) but not syntactically — rw fails. Fix: state hder as the deriv-equality directly via `deriv_comp`? There's `deriv.comp`?? In Mathlib: `deriv_comp (hg : DifferentiableAt 𝕜 g (f x)) (hf : DifferentiableAt 𝕜 f x) : deriv (g ∘ f) x = deriv g (f x) * deriv f x`?? hmm — for ℂ→ℂ (1-dim): `deriv.comp : deriv (h₂ ∘ h₁) x = deriv h₂ (h₁ x) * deriv h₁ x` — `deriv_comp (hh₂ : DifferentiableAt 𝕜 h₂ (h₁ x)) (hh₁ : DifferentiableAt 𝕜 h₁ x)` ✓ exists. But still the ∘-vs-lambda mismatch in the GOAL: goal `deriv (fun z => Gamma (z/2)) s₀ = ...` — rewrite the goal's lambda to ∘: `show deriv (Complex.Gamma ∘ fun z : ℂ => z / 2) s₀ = _` — is that accepted? (fun z => Gamma (z/2)) vs Gamma ∘ (fun z => z/2): defeq (eta) — `show` with defeq type ✓ works. Then rw [deriv_comp (Complex.differentiableAt_Gamma _ hs) differentiableAt_id.div_const 2's differentiableAt]: ``` have hder : deriv (fun z : ℂ => Complex.Gamma (z / 2)) s₀ = deriv Complex.Gamma (s₀ / 2) * (1 / 2) := by have h1 : deriv (Complex.Gamma ∘ fun z : ℂ => z / 2) s₀ = deriv Complex.Gamma (s₀ / 2) * deriv (fun z : ℂ => z / 2) s₀ := deriv_comp _ (Complex.differentiableAt_Gamma _ hs) (differentiableAt_id.div_const 2) have h2 : deriv (fun z : ℂ => z / 2) s₀ = 1 / 2 := by rw [deriv_div_const, deriv_id''] rw [h1, h2] ``` Hmm — wait deriv_comp signature: `deriv_comp (hh₂ : DifferentiableAt 𝕜 h₂ (h₁ x)) (hh₁ : DifferentiableAt 𝕜 h₁ x) : deriv (h₂ ∘ h₁) x = deriv h₂ (h₁ x) * deriv h₁ x`? Let me double check the arg order and the form (g'*(f') vs (f')*(g') — in 1-dim it's commutative anyway). And `deriv (fun z => z/2) s₀ = 1/2`: deriv_div_const : deriv (fun x => f x / c) x = deriv f x / c; deriv_id'' : deriv id x = 1 — the lambda (fun z => z/2) — is it syntactically `fun z => z / 2` vs `fun z => z / (2:ℂ)` ✓ same. deriv_div_const: `deriv_div_const (c : 𝕜) : deriv (fun x => f x / c) x = deriv f x / c` ✓ with f := fun z => z hmm — (fun z => z) vs id: deriv_id'' : deriv id x = 1 — the lambda might not match id syntactically: `fun z => z` IS id by eta — rw [deriv_id''] expects `deriv id s₀`: use `deriv_id'`? or just: (hasDerivAt_id' s₀).div_const 2 |>.deriv : deriv (fun x => x / 2) s₀ = 1/2 ✓ cleaner: ``` have h2 : deriv (fun z : ℂ => z / 2) s₀ = 1 / 2 := ((hasDerivAt_id' s₀).div_const 2).deriv ``` HasDerivAt.div_const: (hf : HasDerivAt f f' x) : HasDerivAt (fun x => f x / c) (f' / c) x: with f := id-lambda, f' = 1: deriv (fun x => x/2) s₀ = 1/2 ✓ .deriv ✓. And the `show` bridge: the goal after rw [logDeriv_apply] in hf2: `deriv (fun z => Gamma (z / 2)) s₀ / Gamma (s₀ / 2) = (1/2) * digamma (s₀/2)`. My hder is about deriv (fun z => Gamma (z/2)) s₀ — but I prove it via the ∘ form with the show... Let me restructure hf2 cleanly: ``` have hf2 : logDeriv (fun z : ℂ => Complex.Gamma (z / 2)) s₀ = (1 / 2 : ℂ) * Complex.digamma (s₀ / 2) := by rw [logDeriv_apply] have hder : deriv (fun z : ℂ => Complex.Gamma (z / 2)) s₀ = deriv Complex.Gamma (s₀ / 2) * (1 / 2) := by have h1 : deriv (Complex.Gamma ∘ fun z : ℂ => z / 2) s₀ = deriv Complex.Gamma (s₀ / 2) * deriv (fun z : ℂ => z / 2) s₀ := deriv_comp _ (Complex.differentiableAt_Gamma _ hs) (differentiableAt_id.div_const 2) have h2 : deriv (fun z : ℂ => z / 2) s₀ = 1 / 2 := ((hasDerivAt_id' s₀).div_const 2).deriv have h3 : deriv (fun z : ℂ => Complex.Gamma (z / 2)) s₀ = deriv (Complex.Gamma ∘ fun z : ℂ => z / 2) s₀ := rfl rw [h3, h1, h2] rw [hder] have hdig : deriv Complex.Gamma (s₀ / 2) = Complex.digamma (s₀ / 2) * Complex.Gamma (s₀ / 2) := by rw [Complex.digamma_def, logDeriv_apply] field_simp [hne2] rw [hdig] field_simp [hne2] ring ``` h3 by rfl: deriv (fun z => Gamma (z/2)) s₀ vs deriv (Gamma ∘ fun z => z/2) s₀ — defeq, rfl should work (eta). Wait — does `deriv_comp` exist by that exact name? In Mathlib: `deriv_comp (hh₂ : DifferentiableAt 𝕜 h₂ (h₁ x)) (hh₁ : DifferentiableAt 𝕜 h₁ x) : deriv (h₂ ∘ h₁) x = deriv h₂ (h₁ x) * deriv h₁ x` — I believe yes (FDeriv/Basic or Deriv/Basic). There's also `deriv.comp` hmm. Let me just try; fallback: the HasDerivAt.comp route with the show-bridge on the hder's LHS. Also hf1's hbase: drop convert, exact directly. Let me apply these fixes.
Fixing hf1/hf2: drop the fragile `convert`s, use `deriv_comp`, and `field_simp` for the division.

Multiple errors: 1. `Real.pi_lt_315` doesn't exist in this Mathlib. Check the pi bounds: `Real.pi_gt_314` / `Real.pi_lt_315`? Maybe `Real.pi_lt_315` was renamed. Let me grep for pi bounds. 2. digamma_right_le's hdist linarith fail: ‖w+m‖ ≥ |w.re + m| and I need ≥ 1: |w.re+m| could be... w.re + m ≥ 1.75 (m ≥ 0) ⟹ |w.re+m| = w.re+m ≥ 1.75 ≥ 1 ✓: linarith [hwre, h1, h3] — the atoms: h1 : ‖w+↑m‖ ≥ |w.re + ↑m| (after rw [h2] — WAIT: h1's RHS after rw [h2] at h1: h2 says (w+↑m).re = w.re + ↑m — but h1 was |(w + ↑m).re| — after rw, h1 : ‖w + ↑m‖ ≥ |w.re + ↑m| ✓ (context shows that). Then |w.re + ↑m| = w.re + ↑m (positive: w.re ≥ 1.75, m ≥ 0): linarith needs abs_of_nonneg — NOT automatic: linarith doesn't split |·|. Give: have h4 : |w.re + ↑m| = w.re + ↑m := abs_of_nonneg (by linarith [hwre, h3]); linarith [h1, h4, hwre, h3]. 3. `Complex.ofNat_re`/`Complex.ofNat_im` unknown — for (s/2).re: use `Complex.div_ofNat_re`? doesn't exist either maybe. Alternatives: simp [Complex.div_re, Complex.ofNat_re] — ofNat_re unknown. What computes (s/2).re? s/2 with 2 : ℂ OfNat: `Complex.ofNat_re : (OfNat.ofNat n : ℂ).re = n`?? unknown. Try: `Complex.div_re : (z / w).re = (z.re * w.re + z.im * w.im) / (w.re^2 + w.im^2)`?? hmm — for w = 2: messy. There's surely `Complex.ofNat_div_re : (z / ofNat n).re = z.re / n`? Let me grep for div_ofNat_re or similar. Or compute directly: (s/2).re: s/2 = s * (2:ℂ)⁻¹?? Or: have h : (s/2).re = s.re/2 := by rw [Complex.div_re]; simp — try `simp [Complex.div_re]` alone? Let me test variants quickly via a scratch check. Actually — there might be simp lemmas `Complex.div_re_ofNat`... Let me grep for "ofNat" in Complex/Basic for re/im of numerals. 4. himsq's nlinarith fail: `s.im ^ 2 < 100` from |s.im| < 10: nlinarith [him10, abs_nonneg s.im] — needs (|s.im|)² < 100 ⟸ |s.im| < 10 and |s.im| ≥ 0: nlinarith should do: (|s.im|)² < 10²·... it multiplies him10 by itself: him10·him10: |s.im|² < 100 ✓ then sq_abs: s.im² = |s.im|² — need sq_abs rewrite! nlinarith doesn't know s.im² = |s.im|². Fix: have h := sq_abs s.im; nlinarith [him10, abs_nonneg s.im, h] — hmm sq_abs : |x|² = x²: gives |s.im|² = s.im²: nlinarith with that ✓ — or: `nlinarith [him10, abs_nonneg s.im, sq_abs s.im]`? Wait — sq_abs s.im : |s.im| ^ 2 = s.im ^ 2: nlinarith multiplies pairs: him10·him10 gives |s.im|² < 100 (needs |s.im| ≥ 0 ✓): then s.im² = |s.im|² < 100 ✓. Let me: have h1 : s.im ^ 2 = |s.im| ^ 2 := (sq_abs s.im).symm; nlinarith [him10, abs_nonneg s.im, h1]. Hmm nlinarith multiplying him10×him10 — him10 : |s.im| < 10: product with itself: |s.im|² < 10·|s.im|... hmm: a < b and a ≥ 0 ⟹ a² < b²: nlinarith CAN do: (10−|s.im|)·(10+|s.im|) > 0: it considers products of the hypothesis atoms: him10 × him10: |s.im|·|s.im| < 100·... actually nlinarith's certificate: it multiplies PAIRS: (him10) · (him10): |s.im|·|s.im| < 10·10 = 100 — but that's a < b times a < b — the product rule used by nlinarith: (10 − |s.im|) > 0, (10 + |s.im|) > 0: product > 0: 100 − |s.im|² > 0 ✓ nlinarith does consider such products (it multiplies pairs of hypotheses including differences). With h1 in the mix it should close. Let me use: have h1 : s.im ^ 2 = |s.im| ^ 2 := (sq_abs s.im).symm; rw [h1]; nlinarith [him10, abs_nonneg s.im]. 5. Line 3231: the h5/h6/h8 mess in hRmin — I overcomplicated. Let me simplify hRmin's proof: R − |s.re| ≥ 0 from |s.re| ≤ R (abs_re_le_norm + hs). My current code has a garbled h5 with leftover h6/h7/h8 nonsense. Rewrite hRmin cleanly: ``` have hRmin : R - |s.re| < 100 / R := by have h9 : |s.re| ≤ R := by have h10 := abs_re_le_norm s rw [hs] at h10 exact h10 have h1 : (R - |s.re|) * (R + |s.re|) = s.im ^ 2 := by have h2 : (R - |s.re|) * (R + |s.re|) = R ^ 2 - |s.re| ^ 2 := by ring rw [h2, sq_abs] linarith [hre2sq] have h3 : (R - |s.re|) * (R + |s.re|) < 100 := by linarith [h1, himsq] have h4 : (0 : ℝ) < R + |s.re| := by linarith [hRpos, abs_nonneg s.re] have h5 : (R - |s.re|) * R ≤ (R - |s.re|) * (R + |s.re|) := mul_le_mul_of_nonneg_left (by linarith [abs_nonneg s.re] : R ≤ R + |s.re|) (by linarith [h9] : (0 : ℝ) ≤ R - |s.re|) have h6 : (R - |s.re|) * R < 100 := by linarith [h3, h5] exact (mul_lt_mul_right hRpos).mp (by linarith [h6] : (R - |s.re|) * R < 100) ``` Hmm — the last step: (R−|s.re|)·R < 100 ⟹ R−|s.re| < 100/R: (mul_lt_mul_right hRpos).mp : a·R < b·R → a < b: with b := 100/R: 100/R·R = 100 (div_mul_cancel₀ R hRpos.ne'): need the RHS as 100/R·R: `have h7 : (100 : ℝ) / R * R = 100 := div_mul_cancel₀ 100 hRpos.ne'`; exact (mul_lt_mul_right hRpos).mp (by linarith [h6, h7]). Wait — h6 : (R−|s.re|)*R < 100 and I want R−|s.re| < 100/R: mul_lt_mul_right (hRpos : 0 < R) : a * R < b * R ↔ a < b: apply with a := R−|s.re|, b := 100/R: need (R−|s.re|)*R < (100/R)*R: from h6 and h7: (100/R)*R = 100 ✓ linarith. Also the goal form of hRmin was `<` (strict) ✓ fine. 6. hre_neg's proof is also garbled (h10/hsign mess). Rewrite cleanly: ``` have hre_neg : (s / 2).re < 0 := by have h9 : |s.re| ≤ R := by have h10 := abs_re_le_norm s rw [hs] at h10 exact h10 have h14 : (100 : ℝ) / R < 1 := by rw [div_lt_one hRpos] linarith [hR] have h15 : s.re < 0 := by by_contra hcon push Not at hcon have h16 : s.re / 2 ≥ 0 := by linarith [hcon] -- if re ≥ 0 then re/2 < 1.75 and re > R−100/R (from hRmin + sign) — wait no: hRmin bounds R−|re|: with re ≥ 0: |re| = re: R−re < 100/R: re > R−100/R > R−1 > 1.75·2: re/2 > 1.75 — contradiction with hre2 rw [hre] at hre2 have h17 : |s.re| = s.re := abs_of_nonneg hcon have h18 : R - s.re < 100 / R := by rw [← h17]; exact hRmin have h19 : (1.75 : ℝ) * 2 < s.re := by linarith [h18, hR, h14] linarith [h19, hre2, h16] rw [hre] linarith [h15] ``` Hmm wait — the branch analysis: hre2 : (s/2).re < 1.75. If s.re ≥ 0: |s.re| = s.re: hRmin: R−s.re < 100/R ⟹ s.re > R−100/R ≥ R−1 ≥ 16001: s.re/2 > 8000 ≥ 1.75 — contradicts hre2 (rw [hre] at hre2: s.re/2 < 1.75). So s.re < 0 ✓ then (s/2).re = s.re/2 < 0 ✓. Hmm — but actually the branch: hre2 says re(s/2) < 1.75 — with s.re ≥ 0 ⟹ re(s/2) = s.re/2 ≥ 0: could be anywhere in [0, R/2]. The contradiction route works ✓. 7. hlt (the s.re/2 + R/2 < 50/R) is also garbled. Rewrite: ``` have hlt : s.re / 2 + R / 2 < 50 / R := by -- |s.re| = −s.re (s.re < 0 from hre_neg's internals) ⟹ R−(−s.re) = R+s.re < 100/R have h15 : s.re < 0 := by by_contra hcon push Not at hcon have h17 : |s.re| = s.re := abs_of_nonneg hcon have h18 : R - s.re < 100 / R := by rw [← h17]; exact hRmin rw [hre] at hre2 have h14 : (100 : ℝ) / R < 1 := by rw [div_lt_one hRpos] linarith [hR] linarith [h18, hR, h14, hre2] have h19 : R + s.re < 100 / R := by have h20 : |s.re| = -s.re := abs_of_neg h15 have h21 : R - (-s.re) < 100 / R := by rw [← h20]; exact hRmin linarith [h21] linarith [h19] ``` Wait — hlt : s.re/2 + R/2 < 50/R: s.re/2 + R/2 = (s.re + R)/2 < (100/R)/2 = 50/R ⟸ R+s.re < 100/R ✓ h19. And hge : 0 ≤ s.re/2+R/2 ⟸ s.re ≥ −R (|s.re| ≤ R ⟹ −R ≤ s.re) ✓. Hmm — but hre_neg's proof ALSO derives s.re < 0 — and hlt needs s.re < 0 too. Since hre_neg comes BEFORE hlt in my layout (hre_neg at line ~3230, hdist later), I can reuse: hre_neg : (s/2).re < 0 ⟹ s.re < 0 (rw [hre] at hre_neg: s.re/2 < 0 ⟹ s.re < 0 ✓). So in hdist's hlt: have h15 : s.re < 0 := by have := hre_neg; rw [hre] at this; linarith. Clean. But wait — hre_neg is proved BEFORE hdist ✓ and uses hRmin + hre2 ✓. Then in hdist: hge uses |s.re| ≤ R ✓; hlt uses hre_neg → s.re < 0 + hRmin ✓. Let me also fix the h4 in hdist (the |x+m| ≥ |m−R/2|−(x+R/2)) — the h6/h7/h8 mess: simplify: ``` have h4 : |(m : ℝ) - R / 2| - (s.re / 2 + R / 2) ≤ |s.re / 2 + (m : ℝ)| := by have h5 : (m : ℝ) - R / 2 = (s.re / 2 + (m : ℝ)) - (s.re / 2 + R / 2) := by ring rw [h5] exact abs_sub_abs_le_abs_sub _ _ ``` abs_sub_abs_le_abs_sub (a b : α) : |a| − |b| ≤ |a − b|: with a := s.re/2+m, b := s.re/2+R/2: |s.re/2+m| − |s.re/2+R/2| ≤ |(s.re/2+m) − (s.re/2+R/2)| = |m−R/2| hmm — direction: I want |m−R/2| − (s.re/2+R/2) ≤ |s.re/2+m|: from |a|−|b| ≤ |a−b| with a−b = m−R/2: |a|−|b| ≤ |m−R/2| — wrong direction. Use: |m−R/2| = |(s.re/2+m) − (s.re/2+R/2)| ≥ |s.re/2+m| − |s.re/2+R/2| (abs_sub_abs_le_abs_sub (s.re/2+m) (s.re/2+R/2)) ⟹ |s.re/2+m| ≥ |m−R/2| − |s.re/2+R/2| = |m−R/2| − (s.re/2+R/2) (s.re/2+R/2 ≥ 0 ✓ abs_of_nonneg). So: ``` have h4 : |(m : ℝ) - R / 2| - (s.re / 2 + R / 2) ≤ |s.re / 2 + (m : ℝ)| := by have h5 : |(s.re / 2 + (m : ℝ)) - (s.re / 2 + R / 2)| = |(m : ℝ) - R / 2| := by have h6 : (s.re / 2 + (m : ℝ)) - (s.re / 2 + R / 2) = (m : ℝ) - R / 2 := by ring rw [h6] have h7 := abs_sub_abs_le_abs_sub (s.re / 2 + (m : ℝ)) (s.re / 2 + R / 2) rw [h5] at h7 have h8 : |s.re / 2 + R / 2| = s.re / 2 + R / 2 := abs_of_nonneg hge linarith [h7, h8] ``` ✓. Then final: ‖s/2+m‖ ≥ |s.re/2+m| ≥ |m−R/2| − 50/R ≥ 1/4 − 50/R ≥ 1/8: linarith [h1, h4, hgap', h9, hlt, h50]: h4 : |m−R/2| − (s.re/2+R/2) ≤ |s.re/2+m|; hgap' : 1/4 ≤ |R/2−m| = |m−R/2| (h9); hlt : s.re/2+R/2 < 50/R; h50 : 50/R ≤ 1/8. Chain: |s.re/2+m| ≥ 1/4 − 50/R ≥ 1/4 − 1/8 = 1/8 ✓ linarith ✓. 8. Real.pi_gt_three exists (used in norm_logPi_div_two_le) ✓ I think. Let me check the pi_lt name — grep Mathlib for pi_lt.
Multiple fixes needed. First check the π bounds available in this Mathlib.

`Real.pi_lt_d2 : π < 3.15` exists (d2-style naming). And `Real.pi_gt_three : 3 < π`. Fix: Real.pi_lt_315 → Real.pi_lt_d2 (two places: digamma_right_le and digamma_circle_le, both `Real.pi ≤ 45` bounds — actually with pi_lt_d2 : π < 3.15 I get π < 3.15 ≤ 45 ✓). Now apply all the fixes: pi name, hdist's abs split, himsq's sq_abs, hRmin rewrite, hre_neg rewrite, hlt rewrite, h4 rewrite.
`Real.pi_lt_d2 : π < 3.15`. Now applying the full fix set to c-ii.

Line 3257: the leftover garbled hre_neg/h10 — rewrite. Let me rewrite the whole block from `have hRmin` through the end of `hdist`'s h4 cleanly. Read the current text first to get exact boundaries.
Let me view the garbled region and rewrite it wholesale.

Now I can see the full block. The issues: - hRmin's h5 block (lines 3230-3244): the garbled h6/h7/h8 and the MulLeftStrictMono failure. - hre_neg (3246-3271): `linarith [h10, h14, hsign, h15]` at the end — hsign is out of scope (it's inside the by_cases in h15) — error at 3257/3269 (the h14 : (1.75)*2 ≤ s.re from hre2 — hre2 : (s/2).re < 1.75 WITHOUT rw [hre]: (s/2).re < 1.75 does NOT give s.re/2 < 1.75 unless hre is applied... in hre_neg's hsign branch: `have h14 : (1.75 : ℝ) * 2 ≤ s.re := by linarith [hre2]` — WRONG DIRECTION: hre2 : (s/2).re < 1.75 can't give a LOWER bound on s.re! That's the linarith failure at 3257. My logic: if s.re ≥ 0 then |s.re| = s.re and R−s.re < 100/R ⟹ s.re > R−100/R (large) ⟹ s.re/2 large ≥ 1.75 — contradicting hre2. The `have h14 := ... linarith [hre2]` is bogus. Rewrite per my clean design. - hlt (3289-3300): h13's positive branch `have h14 : (1.75)*2 ≤ s.re := by linarith [hre2]` — same bogus line + the final `linarith [h13, h14]` wrong. - h4 (3305-3317): the h6/h7/h8 mess — replace with the clean version. Let me rewrite lines 3220-3322 (hRmin through hdist's end) with the clean versions.
Rewriting the whole block (hRmin → hdist) with the clean structure.

Do the h21 bridge. Similarly — the h50 : 50/R ≤ 1/8 ✓ fine (constants). Also the final linarith [h1, h4, hgap', h9, hlt, h50]: chain: |s.re/2+m| ≥ |m−R/2| − (s.re/2+R/2): h4; hgap' : 1/4 ≤ |R/2−m| with h9 : |R/2−m| = |m−R/2|: so |m−R/2| ≥ 1/4; hlt : s.re/2+R/2 < 50/R; h50 : 50/R ≤ 1/8: so |s.re/2+m| > 1/4 − 1/8 = 1/8: goal 1/8 ≤ ‖s/2+m‖ with h1 : ‖s/2+m‖ ≥ |s.re/2+m| ✓ linear ✓. Let me fix both spots (div_lt_iff₀ form + the hlt atom bridge).
Two atom-bridge fixes: `div_lt_iff₀`'s left-mult form and the 100/R = 2·(50/R) bridge.

The `(div_lt_iff₀ hRpos).mpr (by rw [h7]; exact h6)` — the div_lt_iff₀'s mpr direction needs the goal `?a < ?b * R` with metavariables for a and b — the `by rw [h7]` inside the mpr argument can't see the goal properly (the expected type has metavariables ?m.1635 < ?m.1634 * R — the div_lt_iff₀'s b is a metavariable because div_lt_iff₀ : a < b / c ↔ a * c < b hmm — wait the form per the error: `?m.1635 < ?m.1634 * R` — so this div_lt_iff₀ is `a < b / c ↔ c * a < b`?? The metavariables aren't determined: div_lt_iff₀ (hc : 0 < c) : a < b / c ↔ a * c < b. mpr : a * c < b → a < b / c. Applied to the goal `R − |s.re| < 100 / R`: mpr needs to unify `?a * R < ?b` — with c := R from hRpos... the (div_lt_iff₀ hRpos) fixes c := R but a, b are metavars. The `by rw [h7]` tactic block runs with goal `?a * R < ?b` — the rw [h7] fails since the goal has metavars not matching R*(R−|s.re|). Fix: pin a,b by giving the exact have: ``` have h8 : R - |s.re| < 100 / R := (div_lt_iff₀ hRpos).mpr (show (R - |s.re|) * R < 100 from h6) exact h8 ``` The `show` ascribes the mpr's input type, pinning a,b ✓. Wait — but which side does c multiply? Error showed `?m.1635 < ?m.1634 * R` — that's a < b*c?? or c*a < b? The pattern `?m.1635 < ?m.1634 * R`: so the iff's RHS is `?a < ?b * R` hmm — that would make div_lt_iff₀ : a / c < b ↔ a < b * c (for 0 < c)! i.e., this Mathlib's div_lt_iff₀ (hc : 0 < c) : a / c < b ↔ a < b * c. My goal: R−|s.re| < 100/R — form `? < ? / ?` — matches `a < b / c` form, not `a / c < b`!! So div_lt_iff₀ : a < b / c ↔ a * c < b has iff-RHS `a * c < b` — pattern `? * R < ?` — but the error pattern is `?m.1635 < ?m.1634 * R` — that's `a < b * c`!!! So this div_lt_iff₀ is `a / c < b ↔ a < b * c` — the OTHER direction: a/c < b ⟺ a < b·c. Then mpr : a < b*c → a/c < b — produces a GOAL of form ?a / R < ?b — not my goal form. WRONG lemma for my goal `R−|s.re| < 100/R` — I need `a < b/c ↔ a*c < b` which is... `lt_div_iff₀ (hc : 0 < c) : a < b / c ↔ a * c < b`! The name is `lt_div_iff₀` (not div_lt_iff₀). And indeed hRmin's GOAL is R−|s.re| < 100/R = a < b/c: use `(lt_div_iff₀ hRpos).mpr (show (R - |s.re|) * R < 100 from h6)`. Hmm — but wait: h50 uses `div_le_iff₀ hRpos : 50/R ≤ 1/8 ⟺ 50 ≤ 1/8·R` — that one worked? It compiled earlier?? h50's proof `rw [div_le_iff₀ hRpos]; linarith [hR]` — no error reported for it... the error list only had 3235 and 3291. So div_le_iff₀ worked for `50/R ≤ 1/8` — consistent with `div_le_iff₀ (hc : 0 < c) : a / c ≤ b ↔ a ≤ b * c` ✓. So for my goal a < b/c the right name is lt_div_iff₀. 2. Line 3291 (the final linarith of hdist): `linarith [h1, h4, hgap', h9, hlt, h50]` failed. The chain: h1 : ‖s/2+m‖ ≥ |s.re/2+m|; h4 : |m−R/2| − (s.re/2+R/2) ≤ |s.re/2+m|; hgap' : 1/4 ≤ |R/2−(m:ℝ)| (after hcast); h9 : |R/2−(m:ℝ)| = |m−R/2|; hlt : s.re/2+R/2 < 50/R; h50 : 50/R ≤ 1/8. Goal: 1/8 ≤ ‖s/2+m‖. Chain: ‖s/2+m‖ ≥ |s.re/2+m| ≥ |m−R/2| − (s.re/2+R/2) ≥ 1/4 − 50/R ≥ 1/4−1/8 = 1/8 ✓ all linear... but h50 : 50/R ≤ 1/8 has the atom 50/R and hlt has 50/R ✓ same atom. hgap'/h9 bridge the abs forms ✓ in context. Why fail?! Maybe hgap's form: hgapInt (m:ℤ) : 1/4 ≤ |R / 2 - ((m:ℤ):ℝ)| — hcast : ((m:ℤ):ℝ) = (m:ℝ) — rw [hcast] at hgap' — gives 1/4 ≤ |R/2 − (m:ℝ)| ✓ and h9 : |R/2 − (m:ℝ)| = |m − R/2| ✓ — all fine... Let me look at the actual error state — need more of the error output. Let me recompile and see.
`div_lt_iff₀` here is the `a/c < b` form — for `a < b/c` the name is `lt_div_iff₀`. Fix, then recheck the hdist failure.

Two things: 1. Line 3290 (hdist's final linarith): the goal is h4's statement `|(m:ℝ) − R/2| − (s.re/2+R/2) ≤ |s.re/2+(m:ℝ)|` — WAIT the error is at 3290:10 with a✝ : |s.re/2+↑m| < |↑m−R/2| − (s.re/2+R/2) — that's h4's GOAL (negated) — the failure is INSIDE h4's proof: `linarith [h7, h8]`. h7 : |s.re/2+↑m| − |s.re/2+R/2| ≤ |↑m−R/2| — hmm! The abs_sub_abs_le_abs_sub I used: abs_sub_abs_le_abs_sub (a b) : |a| − |b| ≤ |a − b| — with a := s.re/2+↑m, b := s.re/2+R/2: gives |a|−|b| ≤ |a−b| = |↑m−R/2| — that's |x|−|y| ≤ |m−R/2| — and h4's goal: |m−R/2| − y ≤ |x|: from |x|−|y|... wait: h7 : |x| − |y| ≤ |m−R/2| where x := s.re/2+↑m, y := s.re/2+R/2: goal: |↑m−R/2| − y ≤ |x| with y = s.re/2+R/2 ≥ 0 (h8 : |y| = y): from h7: |x| ≤ |m−R/2| + |y| — wrong direction!!! I need |m−R/2| − y ≤ |x| ⟺ |m−R/2| ≤ |x| + y: and h7 gives |x| ≤ |m−R/2| + y. WRONG DIRECTION. The correct inequality: |m−R/2| = |(s.re/2+↑m) − (s.re/2+R/2)| ≥ |s.re/2+↑m| − |s.re/2+R/2| — I have exactly that as h7 — |x|−|y| ≤ |m−R/2| ⟹ |m−R/2| ≥ |x|−|y| ⟹ |m−R/2| + |y| ≥ |x|... no wait: goal: |m−R/2| − y ≤ |x| ⟺ |m−R/2| ≤ |x| + y ⟺ ... from h7 : |x| − y ≤ |m−R/2| (h8): |x| − y ≤ |m−R/2| ⟹ |m−R/2| ≥ |x| − y ⟹ |m−R/2| + y ≥ |x| — STILL wrong direction!! I mixed myself up. What I actually need: |x + m| = |(m−R/2) + (x+R/2)| ≥ |m−R/2| − (x+R/2) — the REVERSE triangle on the SUM: |A + B| ≥ |A| − |B| with A := m−R/2, B := x+R/2: |A+B| ≥ |A|−|B| ✓. |A|−|B| ≤ |A+B| is `abs_sub_abs_le_abs_sub A (−B)`? |A − (−B)| = |A+B| and |A|−|−B| = |A|−|B|: abs_sub_abs_le_abs_sub A (−B) : |A| − |−B| ≤ |A − (−B)| = |A+B| ✓. So: ``` have h7 := abs_sub_abs_le_abs_sub ((m : ℝ) - R / 2) (-(s.re / 2 + R / 2)) rw [abs_neg, sub_neg_eq_add] at h7 -- h7 : |(m : ℝ) - R / 2| - |s.re / 2 + R / 2| ≤ |(m : ℝ) - R / 2 + (s.re / 2 + R / 2)| -- and (m−R/2) + (s.re/2+R/2) = s.re/2 + m (ring) have h5 : (m : ℝ) - R / 2 + (s.re / 2 + R / 2) = s.re / 2 + (m : ℝ) := by ring rw [h5] at h7 -- h7 : |m − R/2| − |s.re/2+R/2| ≤ |s.re/2 + m| -- with h8 : |s.re/2+R/2| = s.re/2+R/2: h4 follows by linarith [h7, h8] ``` ✓ that's the right direction. My earlier h5/h7 had it backwards (I applied abs_sub_abs_le_abs_sub to (x+m) and (x+R/2) getting |x+m|−|x+R/2| ≤ |m−R/2| — which is TRUE but the wrong direction for h4). Hmm wait — but actually h4's goal was written as `|(m:ℝ) − R/2| − (s.re/2+R/2) ≤ |s.re/2+(m:ℝ)|` — and the current (broken) attempt had h7 : |x|−|y| ≤ |m−R/2| — from which the goal does NOT follow. The a✝ shows the negation of h4's goal ✓ consistent. Fix per above. 2. The simp warnings for hre/him2 (Complex.div_re/div_im unused) — the simp closed them via other lemmas (probably div_ofNat or ofNat lemmas fired automatically). Clean: change `simp [Complex.div_re]` → `simp`, same for div_im.
`h7` had the reverse-triangle in the wrong direction. Fixing with `abs_sub_abs_le_abs_sub A (−B)`, and the simp-arg warnings.

Errors: 1. Line 3390 (hnnR): my `mul_nonneg (mul_nonneg (by norm_num) hA0) (mul_nonneg hĈpos.le (pow_two_nonneg _))` — the term is `300 * A0count * C0hat(...) * (Real.log R)^2` parsed as `((300 * A0count) * C0hat(...)) * (Real.log R)^2` — hmm: `300 * A0count * C0hat(...) * (Real.log R)^2` = ((300·A0)·Ĉ)·L²: mul_nonneg (0 ≤ 300·A0·Ĉ) (0 ≤ L²): inner mul_nonneg (0 ≤ 300·A0) (0 ≤ Ĉ): = mul_nonneg (mul_nonneg (by norm_num) hA0) hĈpos.le — I wrote the nesting wrong (the (pow_two_nonneg _) went to the wrong layer). Fix: ``` exact mul_nonneg (mul_nonneg (mul_nonneg (by norm_num) hA0) hĈpos.le) (pow_two_nonneg _) ``` 2. Line 3400 (hζs): `exact hsz hn` — in the ⟨n, hn, h2n⟩ case I named the nontrivial-zero proof `hn` but hn is `1 ≤ n`!! The rcases pattern: `rcases zeta_zero_classification h with hn | h0 | ⟨n, hn, h2n⟩` — the first branch hn : IsNontrivialZero s ✓, but the error at 3400 is in the `by_cases hcase : 2 ≤ s.re · exact hsz hn` — hn there refers to... the rcases's third branch is inside scope: the `⟨n, hn, h2n⟩` destructuring — hn : 1 ≤ n — and in the hcase branch I wrote `exact hsz hn` — hn is 1 ≤ n not IsNontrivialZero s. WAIT — the structure: the THIRD rcases branch is `⟨n, hn, h2n⟩` and within it I case-split. But I need IsNontrivialZero s somewhere in that branch?? NO — in the third branch (s = −2n), hcase : 2 ≤ s.re: s = −2n with re ≥ 2: −2n ≤ −2 < 2 — contradiction directly! I wrote `exact hsz hn` which is nonsense (hsz needs IsNontrivialZero s). The correct contradiction in that branch: s = −2n, n ≥ 1: re s = −2n ≤ −2 < 2: linarith with hcase. Hmm — but actually wait: do I even reach the hcase branch with s = −2n? The third branch's content: by_cases hcase : 2 ≤ s.re: - if 2 ≤ s.re: s = −2n ⟹ re s = −2n ≤ −2 < 2: contradiction: `have hre2 : s.re = -2 * (n:ℝ) := ...; have hnn : (1:ℝ) ≤ (n:ℝ) := ...; linarith [hcase, hre2, hnn]`. - else as before. Hmm — actually hold on: the hζs proof structure I wrote: rcases ... with hn | h0 | ⟨n, hn, h2n⟩: first branch `exact hsz hn` ✓ (line ~3399); the error at 3400 is inside the THIRD branch's `by_cases hcase : 2 ≤ s.re · exact hsz hn` — hn there is (1 ≤ n) ✗. But WAIT — actually the region logic: the hcase/hcase2 split was for the −2n case where I show n = 1 and ‖s‖ = 2 < R. The `exact hsz hn` in the hcase branch should be the contradiction from re: s = −2n with re ≥ 2 impossible. And the hcase2-else branch `exact hsz hn` — also wrong: s = −2n with re < −5/2: ‖s‖ = 2n ≥ 2·3 = 6?? hmm: re s = −2n < −5/2 ⟹ n > 5/4 ⟹ n ≥ 2: ‖s‖ = 2n ≥ 4: but ‖s‖ = R — no contradiction with R!! Hmm — WAIT. s = −2n with re s < −5/2: n ≥ 2: s = −4, −6, ...: ‖s‖ = 2n = R — POSSIBLE?! s = −R with R = 2n an even integer — BUT hgapInt forbids R/2 ∈ ℤ ⟹ R ∉ 2ℤ ✓!! I need hgapInt here: R = 2n ⟹ R/2 = n ∈ ℤ ⟹ |R/2 − n| = 0 < 1/4 ✗. So the else branch: s = −2n with re s < −5/2 (n ≥ 2): R = ‖s‖ = 2n: hgapInt (n : ℤ): |R/2 − n| = |n − n| = 0 < 1/4 ✗. And the hcase branch (2 ≤ s.re): impossible since re s = −2n ≤ −2: linarith. And the middle (re ∈ [−5/2, 2]): n = 1 ⟹ ‖s‖ = 2 < R ✓ (existing code). Hmm wait — actually my original design had the region-split INSIDE hζs duplicating the outer region split — that's silly. SIMPLIFY: prove hζs WITHOUT the region cases: s = −2n: either n = 1 (‖s‖ = 2 < R) or n ≥ 2: R = 2n: but R/2 = n ∈ ℤ contradicts hgapInt. That's it — no region cases needed: ``` have hζs : riemannZeta s ≠ 0 := by intro h rcases zeta_zero_classification h with hn | h0 | ⟨n, hn, h2n⟩ · exact hsz hn · rw [h0, norm_zero] at hs linarith [hs, hR] · -- s = −2n: R = 2n; if n ≥ 2 then R/2 = n ∈ ℤ contradicts hgapInt; n = 1: ‖s‖ = 2 < R have hnorm : ‖s‖ = 2 * (n : ℝ) := by rw [h2n] rw [show (-2 : ℂ) = ((-2 : ℝ) : ℂ) by push_cast; ring, norm_mul, Complex.norm_real, Complex.norm_natCast] norm_num [abs_of_nonneg (Nat.cast_nonneg n : (0 : ℝ) ≤ (n : ℝ))] -- hmm: ‖(-2:ℂ) * (n:ℂ)‖ = ‖(-2:ℂ)‖ * ‖(n:ℂ)‖ = 2 * n rw [hs] at hnorm have hnn : (1 : ℝ) ≤ (n : ℝ) := by exact_mod_cast hn by_cases hn2 : n = 1 · rw [hn2] at hnorm push_cast at hnorm linarith [hnorm, hR] · have hn3 : (2 : ℝ) ≤ (n : ℝ) := by have h4 : 2 ≤ n := by omega exact_mod_cast h4 have hR2n : R / 2 = (n : ℝ) := by linarith [hnorm] have hgap' := hgapInt (n : ℤ) have hcast : ((n : ℤ) : ℝ) = (n : ℝ) := by push_cast; ring rw [hcast, ← hR2n] at hgap' rw [show R / 2 - R / 2 = (0 : ℝ) by ring, abs_zero] at hgap' norm_num at hgap' ``` The norm computation: ‖(-2:ℂ)·(n:ℂ)‖ = ‖(-2:ℂ)‖·‖(n:ℂ)‖ = 2·|↑n| = 2·↑n (n ≥ 0): ``` have hnorm : ‖s‖ = 2 * (n : ℝ) := by rw [h2n, norm_mul] have h1 : ‖(-2 : ℂ)‖ = 2 := by rw [show (-2 : ℂ) = ((-2 : ℝ) : ℂ) by push_cast; ring, Complex.norm_real] norm_num rw [h1, Complex.norm_natCast] ``` ‖(↑n : ℂ)‖ = ↑n??

Wait — hold on, do I even USE hgapInt in hζs... yes the n ≥ 2 branch ✓. But note the middle branch (n = 1): R = 2·1 = 2: contradicts R ≥ 16002 ✓. Hmm — but ALSO: the n ≥ 2 branch: R = 2n ⟹ R/2 = n: hgapInt (n:ℤ) : 1/4 ≤ |R/2 − ↑n| = 0 ✗ ✓. 3. dirichletC2_nonneg — does it exist? I used it twice. It's NOT in the file (I haven't proved it). dirichletC2 := ∑' n, ‖term...‖ ≥ 0 (tsum of norms ≥ 0): need a small lemma: ``` lemma dirichletC2_nonneg : (0 : ℝ) ≤ dirichletC2 := tsum_nonneg (fun n => norm_nonneg _) ``` `tsum_nonneg (hf : ∀ i, 0 ≤ f i) : 0 ≤ ∑' i, f i` ✓ exists. Add it. Let me fix all three.
Three fixes: hnnR's nesting, the hζs restructure (using hgapInt for n ≥ 2, no region duplication), and `dirichletC2_nonneg` doesn't exist yet.

Line 3466 (hnear's separation step): `(one_div_le_one_div_of_le h2 hsep).trans_eq (one_div_one_div _)` — the expected final: `1/‖s−ρ‖ ≤ 32·Ĉ₀`: one_div_le_one_div_of_le (ha : 0 < a) (h : a ≤ b) : 1/b ≤ 1/a — with a := ‖s−ρ‖, b := 1/(32Ĉ₀)?? wait: hsep : 1/(32Ĉ₀) ≤ ‖s−ρ‖: one_div_le_one_div_of_le (hx : 0 < x) (hxy : x ≤ y) : 1/y ≤ 1/x — with x := 1/(32Ĉ₀) (positive h1) and y := ‖s−ρ‖: gives 1/‖s−ρ‖ ≤ 1/(1/(32Ĉ₀)) — I passed h2 (0 < ‖s−ρ‖) as the FIRST arg — WRONG: the signature: `one_div_le_one_div_of_le (ha : 0 < a) (hab : a ≤ b) : 1 / b ≤ 1 / a` — the FIRST arg is positivity of a (the SMALLER one). So: one_div_le_one_div_of_le h1 hsep : 1/‖s−ρ‖ ≤ 1/(1/(32Ĉ₀)) — then .trans_eq (one_div_one_div _ : 1/(1/x) = x) : 1/‖s−ρ‖ ≤ 32Ĉ₀ ✓. Fix: swap h2 → h1: `(one_div_le_one_div_of_le h1 hsep).trans_eq (one_div_one_div _)`. 2. Line 3475 (hmax's h2): `abs_add_le _ _` gives |?a + ?b| ≤ |?a|+|?b| — expected |s.im + 1| ≤ |s.im| + 1: |(−1)| = 1 — the (1 : ℝ) is fine but abs_add_le _ _ unifies to |s.im + 1| ≤ |s.im| + |1| — the RHS |1| vs 1 mismatch: |1| = 1 needs abs_of_pos or norm_num. Fix: `have h1 : |s.im + 1| ≤ |s.im| + 1 := by have h := abs_add_le s.im (1 : ℝ); rwa [abs_one] at h`. abs_one : |1| = 1 ✓. Also the hmax block has that monstrous by_cases' garbage I accidentally generated (the `.by_cases'` chain) — that's broken anyway. Let me rewrite hmax cleanly: ``` have hmax : max |s.im - 1| |s.im + 1| ≤ |s.im| + 1 := by apply max_le_iff.mpr exact ⟨by have h4 : s.im - 1 = s.im + (-1 : ℝ) := by ring rw [h4] have h := abs_add_le s.im (-1 : ℝ) rwa [abs_neg, abs_one] at h, by have h := abs_add_le s.im (1 : ℝ) rwa [abs_one] at h⟩ ``` Then use log(3·max+5) ≤ log(3(|t|+1)+5): Real.log_le_log (pos) (mul_le_mul_of_nonneg_left hmax (by norm_num)) — the hmax EQUALITY isn't needed; ≤ suffices and is 5 lines. Adjust the downstream: I had `rw [hmax]` — change to bound: log(3·max|t−1||t+1|+5) ≤ log(3(|t|+1)+5) via log_le_log + mul_le_mul + add_le_add_right. 3. Line 3523 (hcap's 5c application): `logDeriv_riemannZeta_sub_nearZeros_le (t := s.im) ht10 rfl hhalf (...≤ 7/2) hζs` — the elaboration blew up: the `rfl` for hsim : s.im = t with t := s.im — should be fine... The error shows the 7/2 bound's proof being elaborated weirdly — `le_of_not_gt fun a => lt_irrefl (Eq.mp ...)` — the linarith inside produced garbage? The `(by linarith [hreg1.le] : s.re ≤ 7 / 2)` — hreg1 : ¬2 ≤ s.re: hreg1.le : s.re ≤ 2?? NO — `not_le.mp hreg1 : s.re < 2` — I wrote `hreg1.le` — that's le_of_not_ge hreg1 : s.re < 2 — .le gives s.re ≤ 2 ✓ then s.re ≤ 7/2 by linarith ✓. Hmm — but the error shows the application itself mismatched: maybe the ISSUE is `rfl : s.im = s.im` with the named arg (t := s.im) — hsim : s.im = t — t is assigned s.im ✓ rfl should work... The error's elaborated garbage is from linarith's internals leaking (the ring normalization failed). The message is truncated — the mismatch might be hζs's TYPE: logDeriv_riemannZeta_sub_nearZeros_le's hs0 : riemannZeta s ≠ 0 ✓ hζs ✓. Or ht10 : 10 ≤ |s.im| — the capstone's ht : 10 ≤ |t| with t := s.im: 10 ≤ |s.im| ✓ ht10 ✓. Hmm — or hhalf : (1:ℝ)/2 ≤ s.re vs the capstone's hσlo : 1/2 ≤ s.re — (1:ℝ)/2 vs 1/2 — same term? `1/2` as ℝ: HDiv 1 2 ✓ same. The `(by linarith [hreg1.le] : s.re ≤ 7 / 2)` — maybe linarith failed and the garbage is its failure state (the "lt_irrefl (Eq.mp (congrArg ...))" IS linarith's internal error form when it fails). Why would s.re ≤ 7/2 fail from s.re < 2? `hreg1.le` — hreg1 : ¬ 2 ≤ s.re: `not_le.mp hreg1 : s.re < 2` — but I wrote `hreg1.le` — is `.le` valid on a Not? `lt_of_not_ge hreg1` is the way; `hreg1.le` might not elaborate (Not has no .le). THAT's likely it — le_of_lt? For ¬(2 ≤ s.re), `hreg1.le` — Dot-notation on a proof of ¬p: ¬p = (p → False): hreg1.le : ... doesn't exist — elaborator garbage. Fix: `(by linarith [lt_of_not_ge hreg1] : s.re ≤ 7 / 2)`. Also earlier `hreg1.le` appears in hcap's first branch AND `hreg1.le` in ht10's h1 pair `⟨hreg2, hreg1.le⟩` — same fix: lt_of_not_ge hreg1. And in hcap's second branch: `(by linarith [hhalf] : s.re ≤ 1 / 2)` — hhalf (pushed) : ¬1/2 ≤ s.re: lt_of_not_ge hhalf : s.re < 1/2: linarith gives ≤ ✓ — hhalf was pushed with `push Not at hhalf` giving s.re < 1/2 directly ✓ fine. Hmm wait — in ht10's hre25: `have h1 : -5 / 2 ≤ s.re ∧ s.re ≤ 2 := ⟨hreg2, hreg1.le⟩` — hreg1.le same issue: use (lt_of_not_ge hreg1).le. 4. The hcap's whole structure — the error mentions 3523 which is the 5c branch. Fix hreg1.le occurrences. Let me apply these fixes.
Fixes: `one_div_le_one_div_of_le` arg order, `abs_one` for the |+1| forms, hmax simplified to ≤, and `hreg1.le` → `lt_of_not_ge`.

Errors: 1. `lt_of_not_ge hreg1` — hreg1 was PUSHED: `push Not at hreg1` converted ¬(2 ≤ s.re) to (s.re < 2)! So hreg1 is already s.re < 2 — no lt_of_not_ge needed: just use hreg1 directly (s.re < 2) and hreg1.le. Fix both spots: h1's pair: ⟨hreg2, hreg1.le⟩ — but hreg1 is now < : .le works? For h : s.re < 2, h.le : s.re ≤ 2 ✓. And the 7/2 bound: (by linarith [hreg1] : s.re ≤ 7/2) ✓ (linarith handles <). Wait — I did `push Not at hreg1` after the first by_cases? Let me check: after `by_cases hreg1 : 2 ≤ s.re · ... · push Not at hreg1; by_cases hreg2...`. Yes — hreg1 pushed: type s.re < 2. Fix: revert to hreg1 directly. 2. h1's rw [h3] at h2 — h2's form is `32 * C0hat(...) * (3 * A0count) * Real.log(...) ≤ 32 * C0hat(...) * (3 * A0count) * (2 * Real.log R)` — h3 : 32·Ĉ·(3·A₀·(2L)) = 192·A₀·Ĉ·L — pattern mismatch: the goal has (3 * A0count) * Real.log(...) NOT (3 * A0count * (2 * Real.log R)): mul_le_mul_of_nonneg_left hlogmax gave the bound with `(3 * A0count) * (2 * Real.log R)`?? — no: hlogmax : Real.log(3·max+5) ≤ 2·Real.log R: mul_le_mul_of_nonneg_left hlogmax (0 ≤ 32·Ĉ·(3·A₀)): gives (32·Ĉ·(3·A₀))·Real.log(...) ≤ (32·Ĉ·(3·A₀))·(2·Real.log R) — the error shows the goal form is `32 * C0hat(...) * (3 * A0count) * Real.log(...)` — associativity: `32 * C0hat(...) * (3 * A0count) * X` = ((32·Ĉ)·(3·A₀))·X — hmm that IS the form (32·Ĉ·(3·A₀))·X by left-assoc. So h2 : ... ≤ 32·Ĉ·(3·A₀)·(2L) — and h3 : 32·Ĉ·(3·A₀·(2L)) = ... — DIFFERENT: (3·A₀)·(2L) vs (3·(A₀·(2L)))? `3 * A0count * (2 * Real.log R)` = (3·A₀)·(2L) left-assoc ✓ same as the goal's RHS?? The goal RHS: `32 * C0hat(...) * (3 * A0count) * (2 * Real.log R)` = ((32·Ĉ)·(3·A₀))·(2L) ✓ and h3's LHS: `32 * C0hat(...) * (3 * A0count * (2 * Real.log R))` = (32·Ĉ)·((3·A₀)·(2L)) ✓ same ✓ — so h3 SHOULD rewrite... the error says pattern not found: h3's LHS as I wrote it: `32 * C0hat (4 * ↑k + 9 / 2) * (3 * A0count * (2 * Real.log R))` — vs goal's `32 * C0hat (...) * (3 * A0count) * (2 * Real.log R)` — the difference: (3 * A0count * (2L)) vs ((3 * A0count) * (2L)) — these ARE the same term by left-assoc: 3 * A0count * (2 * Real.log R) parses as (3 * A0count) * (2 * Real.log R) — identical! Hmm — but the error shows h3 wasn't found in the goal `32 * C0hat (...) * (3 * A0count) * Real.log (3 * max ...) ≤ 32 * C0hat (...) * (3 * A0count) * (2 * Real.log R)` — the LHS of the iff... rw [h3] at h2: h2's RHS is `32·Ĉ·(3·A₀)·(2·L)` and h3 : `32·Ĉ·(3·A₀·(2·L))` — the forms: h2's RHS: (32·Ĉ·(3·A₀))·(2·Real.log R); h3's LHS: (32·Ĉ)·((3·A₀)·(2·Real.log R)) — SAME term? (32 * C0hat(...) * (3 * A0count)) * (2 * Real.log R) vs (32 * C0hat(...)) * ((3 * A0count) * (2 * Real.log R)) — associativity of *: (a*b)*c = a*(b*c) — SAME term in Lean? NO — HMul.hMul (HMul.hMul a b) c vs HMul.hMul a (HMul.hMul b c) — DIFFERENT terms (rw is syntactic). So rewrite h3's form to match: h3 : 32 * C0hat(...) * (3 * A0count) * (2 * Real.log R) = 192·A₀·Ĉ·L — as written: `32 * C0hat (4 * (k:ℝ)+9/2) * (3 * A0count) * (2 * Real.log R)` — the parse of that is ((32·Ĉ)·(3·A₀))·(2L) ✓ matches h2's RHS. My h3 was written with explicit parens (3 * A0count * (2 * Real.log R)) — hmm that's ((3·A₀)·(2L)) — and the goal has the same... WAIT the error's goal RHS: `32 * C0hat (4 * ↑k + 9 / 2) * (3 * A0count) * (2 * Real.log R)` — YES and h3's LHS: `32 * C0hat (4 * ↑k + 9 / 2) * (3 * A0count * (2 * Real.log R))` — hmm the goal text shows (3 * A0count) * (2 * Real.log R) — with the OUTER product ((32·Ĉ)·(3·A₀))·(2L)?? The display `32 * C0hat (...) * (3 * A0count) * (2 * Real.log R)` — all left-assoc ✓ and h3's LHS `32 * C0hat (...) * (3 * A0count * (2 * Real.log R))` — the parenthesization (3 * A0count * (2 * Real.log R)) is ((3·A₀)·(2L)) — so h3's LHS = (32·Ĉ)·((3·A₀)·(2L)) — DIFFERENT from ((32·Ĉ)·(3·A₀))·(2L). So the mismatch IS associativity. Fix: restate h3 as `32 * C0hat (...) * (3 * A0count) * (2 * Real.log R) = ...` — wait that's what I need to match: ((32·Ĉ)·(3·A₀))·(2L) — write h3's LHS exactly as the goal's RHS. Change h3 to: ``` have h3 : 32 * C0hat (4 * (k : ℝ) + 9 / 2) * (3 * A0count) * (2 * Real.log R) = 192 * A0count * C0hat (4 * (k : ℝ) + 9 / 2) * Real.log R := by ring ``` Wait — that parses as ((32·Ĉ)·(3·A₀))·(2L) ✓. ring proves ✓. Hmm — but wait, h2 was built as mul_le_mul_of_nonneg_left hlogmax (0 ≤ 32·Ĉ·(3·A₀)) — its RHS form: (32·Ĉ·(3·A₀))·(2·L)?? mul_le_mul_of_nonneg_left (h : b ≤ a) (hc : 0 ≤ c) : c * b ≤ c * a — with c := 32·Ĉ·(3·A₀): c·Real.log(...) ≤ c·(2·L) — the display showed `32 * C0hat (...) * (3 * A0count) * (2 * Real.log R)` — consistent with c := (32·Ĉ·(3·A₀)) hmm — the c I passed: `mul_nonneg (mul_nonneg (by norm_num : (0:ℝ) ≤ 32) hĈpos.le) (mul_nonneg (by norm_num : (0:ℝ) ≤ 3) hA0)` : 0 ≤ (32·Ĉ)·(3·A₀) ✓ so h2 : ((32·Ĉ)·(3·A₀))·log(...) ≤ ((32·Ĉ)·(3·A₀))·(2L) ✓ then h3 must match ((32·Ĉ)·(3·A₀))·(2L) — as the goal shows: `32 * C0hat (...) * (3 * A0count) * (2 * Real.log R)` ✓ parse ((32·Ĉ)·(3·A₀))·(2L) ✓. So restate h3 in THAT form (without the inner parens around (2 * Real.log R)).
Two fixes: `hreg1` was already pushed (use it directly), and h3's associativity must match the goal.

Several mismatches: 1. hcap 5c: the capstone gives ≤ 100000·(log|t|)² but hcap's stated bound is 200000 — need `.trans` with 100000 ≤ 200000: `exact h.trans (by ...)`: (mul_le_mul_of_nonneg_left (by norm_num : (100000:ℝ) ≤ 200000) ...) hmm: 100000·X ≤ 200000·X with X = (log|t|)² ≥ 0: mul_le_mul_of_nonneg_right (by norm_num : (100000:ℝ) ≤ 200000) (pow_two_nonneg _) — wait the forms: 100000 * (Real.log |s.im|)^2 ≤ 200000 * (Real.log |s.im|)^2: mul_le_mul_of_nonneg_right (by norm_num) (pow_two_nonneg _) ✓. So: `exact (logDeriv_riemannZeta_sub_nearZeros_le (t := s.im) ht10 rfl hhalf (by linarith [hreg1] : s.re ≤ 7 / 2) hζs).trans (mul_le_mul_of_nonneg_right (by norm_num : (100000:ℝ) ≤ 200000) (pow_two_nonneg _))`. 2. h1's expected type: `32 * C0hat(...) * (3 * A0count * Real.log(...))` — the h1 in the final calc step of region (ii): its statement was written with (3 * A0count * Real.log(...)) but h2.trans h4 produces (32·Ĉ)·((3·A₀)·(2L)) form... The h1's statement: `32 * C0hat (...) * (3 * A0count * Real.log (3 * max ...)) ≤ 192·A₀·Ĉ·L²` — and h2.trans h4 : `32 * C0hat(...) * (3 * A0count) * Real.log(...) ≤ 192·...` — associativity AGAIN: (32·Ĉ·(3·A₀))·log vs (32·Ĉ)·((3·A₀)·log): h1's statement should be in the produced form: `32 * C0hat (4 * ↑k + 9 / 2) * (3 * A0count) * Real.log (3 * max |s.im - 1| |s.im + 1| + 5) ≤ ...` — i.e. left-assoc (32·Ĉ·(3·A₀))·log. Fix h1's statement: change `(3 * A0count * Real.log (3 * max |s.im - 1| |s.im + 1| + 5))` → `(3 * A0count) * Real.log (3 * max |s.im - 1| |s.im + 1| + 5)`. And hnear's stated bound: `32 * C0hat (...) * (3 * A0count * Real.log (...))` — the calc's mul_le_mul_of_nonneg_left nearZeros_count_le produces (32Ĉ)·(3A₀·log) — as ((32Ĉ))·((3A₀)·log)?? mul_le_mul_of_nonneg_left (h : b ≤ a) (hc : 0 ≤ c) : c * b ≤ c * a: with c := 32Ĉ: (32Ĉ)·(3A₀·log) — the hnear's final stated form: `32 * C0hat (...) * (3 * A0count * Real.log (...))` = (32Ĉ)·((3A₀)·log) ✓ that MATCHED (the calc closed ✓ since no error reported for hnear). Then h1 converts hnear's form to 192...: h1's statement must be EXACTLY hnear's RHS: `32 * C0hat (...) * (3 * A0count * Real.log (3 * max |s.im - 1| |s.im + 1| + 5))` — which is what I wrote... but the error says h2.trans h4 has type `32 * C0hat(...) * (3 * A0count) * Real.log(...)` (left-assoc: ((32Ĉ)·(3A₀))·log) vs h1's expected `32 * C0hat(...) * (3 * A0count * Real.log(...))` ((32Ĉ)·((3A₀)·log)) — DIFFERENT associativity between h2's output and h1's statement. h2 was built via mul_le_mul_of_nonneg_left hlogmax (hc : 0 ≤ (32Ĉ)·(3A₀)) : ((32Ĉ)·(3A₀))·log(...) ≤ ((32Ĉ)·(3A₀))·(2L) — LEFT-assoc ((32Ĉ)·(3A₀))·X. So h2's LHS form: `32 * C0hat (...) * (3 * A0count) * Real.log(...)` (left-assoc). But hnear's RHS (from its calc): the mul_le_mul_of_nonneg_left nearZeros_count_le (by positivity : 0 ≤ 32·Ĉ): (32Ĉ)·(3A₀·log) — RIGHT-nested (32Ĉ)·((3A₀)·log). So hnear's type is `32 * C0hat (...) * (3 * A0count * Real.log (...))` and h2's LHS is `32 * C0hat (...) * (3 * A0count) * Real.log (...)` — DIFFERENT. So h1's statement must start from h2's form (left-assoc): `32 * C0hat (...) * (3 * A0count) * Real.log (...) ≤ ...` — but then the calc step `_ ≤ ...300...` uses h1 : ... and the PREVIOUS calc step gives hnear's right-nested form — mismatch at the calc's `_ ≤ 200000·L|t|² + [right-nested]` — the add_le_add hcap hnear produces `200000·|t|² + (32Ĉ)·((3A₀)·log)` — and the next step's LHS stated as `200000·R² + 300...` — the transition: `_ ≤ dirichletC2 + 200000·L² + 300·A₀ĈL² := by ...nlinarith [hlogt, h1, h5, ...]` — h1 must connect hnear's nested form to 192·A₀ĈL². Simplest: make h1's LHS match h2's form (left-assoc) AND bridge hnear's nested form: change h1's statement to the left-assoc form and in the calc, the add_le_add step... ugh — actually the cleanest: change hnear's FINAL form to the left-assoc too: hnear's last calc step used mul_le_mul_of_nonneg_left nearZeros_count_le (by positivity : (0:ℝ) ≤ 32 * C0hat (...)): (32Ĉ)·(3A₀·log) — nested. If instead I apply it as `mul_le_mul_of_nonneg_left nearZeros_count_le (by positivity : (0:ℝ) ≤ 32 * C0hat (...) * (3 * A0count))` with h'logmax?? no — the count bound is 3A₀·log ≤ 3A₀·2L: TWO steps: first mul_le_mul_of_nonneg_left nearZeros_count_le (0 ≤ 32Ĉ): (32Ĉ)·(3A₀·log) nested; then hlogmax's: mul_le_mul_of_nonneg_left hlogmax (0 ≤ 32Ĉ·3A₀): ((32Ĉ)·(3A₀))·log ≤ ((32Ĉ)·(3A₀))·2L. The two forms differ in nesting of the FIRST two factors. To keep ONE consistent form, make h1's statement match h2's left-assoc form AND adjust the calc's expectation: the calc step `_ ≤ 200000·(log|t|)² + (32Ĉ·(3A₀·log))` (add_le_add hcap hnear) — then the final nlinarith combines with h1 : (32Ĉ)·(3A₀)·log ≤ 192A₀ĈL² — DIFFERENT terms for the near-sum: nlinarith treats them as atoms — the two nestings are DIFFERENT atoms!! linarith/nlinarith won't match them. So: make hnear's final form LEFT-assoc from the start: in hnear's last calc step, instead of `mul_le_mul_of_nonneg_left nearZeros_count_le (by positivity)`, first reshape: `... = (32 * C0hat (...)) * (3 * A0count) * Real.log (...) := by ring` — no wait: (32Ĉ)·(3A₀·log) = ((32Ĉ)·(3A₀))·log by ring (mul_assoc) — add a calc step `_ = 32 * C0hat (...) * (3 * A0count) * Real.log (...) := by ring`? Hmm — mul_assoc: a·(b·c) = (a·b)·c ✓ ring closes. But then hnear's TYPE (the lemma statement) must also be left-assoc: change hnear's statement to `... ≤ 32 * C0hat (...) * (3 * A0count) * Real.log (...)` and internally: after the mul_le_mul step (nested), add `... = (left-assoc form) := by ring` — but ring proves EQUALITY — the calc chain: `... ≤ (32Ĉ)·(3A₀·log) := mul_le_mul... _ = (32Ĉ)·(3A₀)·log := by ring` ✓ — the calc's final form is left-assoc ✓ matching the lemma statement. Hmm wait — the calc currently ends `... := mul_le_mul_of_nonneg_left nearZeros_count_le (by positivity)`. Append a step `... _ = 32 * C0hat (...) * (3 * A0count) * Real.log (...) := by ring`. And change hnear's statement to left-assoc. And h1's statement: starts from the left-assoc: `32 * C0hat (...) * (3 * A0count) * Real.log (3 * max ...) ≤ 192·A₀·Ĉ·L²` — h2's form ✓. Hmm wait — actually h1's statement I wrote: `32 * C0hat (4 * (k:ℝ) + 9 / 2) * (3 * A0count * Real.log (3 * max |s.im - 1| |s.im + 1| + 5))` — nested. Change to left-assoc `(3 * A0count) * Real.log (...)`... wait NO — the error showed h1's EXPECTED type as `32 * C0hat (...) * (3 * A0count * Real.log (...))` (from MY statement) and h2.trans h4's type as `32 * C0hat (...) * (3 * A0count) * Real.log (...)` (left-assoc) — so h2.trans h4 produces LEFT-assoc and my h1 statement was NESTED. Unify everything to LEFT-assoc. 3. Line 3582 (hsR's hm2): `↑(-R) / 2 = -↑m` vs `-↑R / 2 = -↑m` — the hm : s/2 = −↑m with s = ↑(-R): after rw [hsR] at hm: hm : (↑(-R))/2 = −↑m — my h2 : (↑(-R))/2 = ↑(-R/2) — but the elaborator's hm is `↑(-R) / 2` (cast of −R divided by 2) vs my pattern `-(↑R) / 2` — hmm the forms: `(-(R:ℝ) : ℂ) / 2` vs `-((R:ℝ) : ℂ) / 2`?? The hsR : s = (-R : ℝ) — the coercion (↑(-R) : ℂ). hm : (↑(-R))/2 = −↑m. My h2 : (↑(-R) : ℂ)/2 = ((-R/2 : ℝ) : ℂ): push_cast; ring — should prove: (↑(−R))/2 vs ↑(−R/2): push_cast normalizes ↑(−R/2) to (↑(−R))/2?? The error shows h2's produced form mismatched the target `↑(-R) / 2 = -↑m` vs `-↑R / 2 = -↑m` — so after rw [h2] at hm the hm became `↑(-R/2) = -↑m`?? no — the error is in hm2's proof: `rw [h2] at h1` where h1 : (↑(-R))/2 = −↑m — h2's LHS pattern (↑(-R))/2 — is that what h2 says? h2 : (-(R : ℝ) : ℂ) / 2 = ((-R / 2 : ℝ) : ℂ) — the LHS `(-(R:ℝ) : ℂ)/2` vs hm's `↑(-R)/2`: `(-(R:ℝ) : ℂ)` vs `↑(-R)` — SAME? (−R : ℝ) coerced to ℂ = ↑(-R) and (-(R:ℝ) : ℂ) = -↑R — these are DIFFERENT terms (cast-of-neg vs neg-of-cast)! The error message: `↑(-R) / 2 = -↑m` (hm's actual form) vs my h2's `-↑R / 2` — so hm has ↑(-R) (cast first) and my h2 has -↑R. Fix: push_cast at hm FIRST to normalize: or state h2's LHS as (↑(-R) : ℂ)/2. Simplest: in hm2: ``` have hm2 : (m : ℝ) = R / 2 := by have h1 : (-(R : ℝ) : ℂ) / 2 = -(m : ℂ) := hm have h2 : (-R / 2 : ℝ) = -(m : ℝ) := by have h3 : ((-R / 2 : ℝ) : ℂ) = (-(R : ℝ) : ℂ) / 2 := by push_cast; ring rw [h3] at h1?? — hmm direction: I want to convert h1's LHS to a cast form for exact_mod_cast: have h4 : ((-(m : ℝ) : ℝ) : ℂ) = -(m : ℂ) := by push_cast; ring rw [← h3, ← h4] at h1 -- h1 : ((-R/2 : ℝ) : ℂ) = ((-(m:ℝ)) : ℂ) exact_mod_cast h1 linarith [h2] ``` Wait — `(-(m : ℝ) : ℝ)` is just -(m:ℝ) : ℝ; ((-(m:ℝ)) : ℂ) = -(↑m) by push_cast ✓. And ((-R/2 : ℝ):ℂ) = (↑(-R))/2 by push_cast — the push_cast normal form of ↑(−R/2): −(↑R)/2 or ↑(−R)/2? push_cast pushes casts OUT: ↑(−R/2) = (↑(−R))/2 = −(↑R)/2·... cast_neg: ↑(−x) = −↑x: ↑(−R/2) = −(↑(R/2)) = −((↑R)/2) hmm — depends on simp order. The robust way: use congrArg Complex.re on hm: hm : s/2 = −↑m: with s = ↑(−R): (s/2).re = (−↑m).re: (s/2).re = s.re/2 (hre-like: simp) = (↑(-R)).re/2 = −R/2: (−↑m).re = −↑m: so −R/2 = −↑m in ℝ ✓ then m = R/2: ``` have hm2 : (m : ℝ) = R / 2 := by have h1 := congrArg Complex.re hm have h2 : ((-(R : ℝ) : ℂ) / 2).re = -(m : ℝ) := by rw [Complex.neg_re, Complex.natCast_re] at h1 ⊢ ... ``` getting messy. Cleanest robust: avoid congrArg: ``` have hm2 : (m : ℝ) = R / 2 := by have h1 : (↑(-R) : ℂ) / 2 = -(m : ℂ) := hm have h2 : (↑(-R) : ℂ) / 2 = ((-(R / 2) : ℝ) : ℂ) := by rw [show ((-(R / 2) : ℝ) : ℂ) = ((-(R / 2) : ℝ) : ℂ) from rfl] push_cast ring rw [h2] at h1 have h3 : -(R / 2) = -(m : ℝ) := by exact_mod_cast h1 linarith [h3] ``` h2 : (↑(-R))/2 = ↑(-(R/2)): push_cast normalizes ↑(-(R/2)) → ??? push_cast with the `ring` fallback — the goal (↑(-R))/2 = ↑(-(R/2)): push_cast should rewrite ↑(-(R/2)) to -(↑R)/2 and (↑(-R))/2 to -(↑R)/2 hmm — actually `Complex.ofReal_div_ofNat`?? I'm not sure push_cast handles ↑(-R)/2 vs ↑(-(R/2)) — they're EQUAL by ofReal_div + ofReal_neg: ↑(-(R/2)) = -↑(R/2) = -(↑R/2); (↑(-R))/2 = (↑(-R))/2 = (-↑R)/2 = -(↑R/2) ✓ same normal form. push_cast normalizes casts: ofReal_neg, ofReal_div (if exists)... `ofReal_div : (↑(x / y) : ℂ) = ↑x / ↑y` ✓ simp. So push_cast turns ↑(-(R/2)) into -↑R/2 hmm: ↑(−(R/2)): ofReal_neg → −↑(R/2); ↑(R/2): ofReal_div → ↑R/↑2 = ↑R/2: so −(↑R/2). And (↑(−R))/2: −↑R/2 ✓ same ✓ then ring (or rfl-close). Alternatively MUCH simpler: skip hsR's complex detour — hm : s/2 = −↑m and hsR : s = ↑(-R): rw [hsR] at hm gives hm : (↑(-R))/2 = −↑m: apply congrArg Complex.re: ((↑(-R))/2).re = (−↑m).re: LHS: ((↑(-R))/2).re: simp: ((↑(-R)).re)/2 = (−R)/2: ((−R:ℂ)).re = −R (Complex.ofReal_re) — via simp [Complex.ofReal_re] hmm: (↑(-R) : ℂ) = ((−R : ℝ) : ℂ): ofReal(−R): re = −R ✓ ((−R:ℂ)/2).re = −R/2: simp should do: `have h1 := congrArg Complex.re hm; simp [Complex.ofReal_re] at h1` — after simp, h1 : −R/2 = −↑m (in ℝ with casts) — then exact_mod_cast/linarith. The RHS (−↑m).re = −↑m (neg_re + natCast_re) ✓ simp handles. Let me do that: ``` have hm2 : (m : ℝ) = R / 2 := by have h1 := congrArg Complex.re hm simp only [Complex.neg_re, Complex.natCast_re] at h1 have h2 : ((-(R : ℝ) : ℂ) / 2).re = -R / 2 := by simp rw [hsR] at hm?? ``` OK let me look at the actual current code around 3582 to write the precise fix. The current: ``` rw [hsR] at hm have hm2 : (m : ℝ) = R / 2 := by have h2 : (-(R : ℝ) : ℂ) / 2 = ((-R / 2 : ℝ) : ℂ) := by push_cast; ring have h3 : (-R / 2 : ℝ) = -(m : ℝ) := by have h1 : (-(R : ℝ) : ℂ) / 2 = -(m : ℂ) := hm rw [h2] at h1 have h4 : ((-R / 2 : ℝ) : ℂ) = -(m : ℂ) := h1 have h5 : (-R / 2 : ℝ) = -(m : ℝ) := by exact_mod_cast h4 exact h5 linarith [h3] ``` Error: after rw [h2] at h1: h1 : ((-R/2 : ℝ) : ℂ) = −(m:ℂ)?? — the error said "has type ↑(-R) / 2 = -↑m but expected -↑R / 2 = -↑m" — so hm's actual form after rw [hsR] is `↑(-R) / 2 = -↑m` and my h1's stated form `(-(R : ℝ) : ℂ) / 2 = -(m : ℂ)` MISMATCHES (the have h1 : ... := hm ascription failed). Fix: change h1's form to `((-R : ℝ) : ℂ) / 2 = -(m : ℂ)` — matching hm's `↑(-R) / 2 = -↑m`: `(-R : ℝ)` vs `-(R : ℝ)` — hsR : s = (-R : ℝ) — the term I wrote in hsR's statement: `s = (-R : ℝ)` — parsed as `s = ↑(-R)`?? `(-R : ℝ)` is −R : ℝ then coerced — `↑(-R)`. My h1 wrote `(-(R : ℝ) : ℂ)` — neg-of-cast — mismatch. Unify: change hsR's statement to `s = ((-R : ℝ) : ℂ)` and hm2's h1 to the same form, with h2 : (((-R : ℝ):ℂ))/2 = ((-R/2 : ℝ):ℂ) via push_cast; ring — hmm push_cast on `↑(-R)/2 = ↑(-R/2)`: RHS ↑(-R/2) → -↑R/2 (ofReal_neg + ofReal_div + ofReal... ); LHS ↑(-R)/2 → (-↑R)/2 → -(↑R/2)?? ofReal_neg then div: (-↑R)/2 = -(↑R/2)? ofReal_div on LHS: ↑(-R)/↑2 hmm — actually ↑(-R)/2 : the /2 is complex division: ((↑(-R)) : ℂ)/((2:ℕ):ℂ)?? the 2 is OfNat — ↑(-R)/2: HDiv ↑(-R) 2: push_cast: no cast on the whole (it's already a complex division of a cast): hmm — push_cast pushes the INNER cast: ↑(-R) → -↑R (ofReal_neg): LHS becomes (-↑R)/2 = -(↑R/2)? that's ring-level. RHS ↑(-(R/2)): ofReal_neg → -↑(R/2); ofReal_div → -(↑R/↑2) hmm ↑(R/2) → ↑R/2 (ofReal_div — is ofReal_div a simp/push_cast lemma? `ofReal_div : (↑(x / y)) = ↑x / ↑y` — yes simp). So both sides -(↑R/2)... LHS: (-↑R)/2 — ring normalizes to -(↑R/2)? then `ring` closes ✓. So: ``` have hm2 : (m : ℝ) = R / 2 := by have h1 : ((-R : ℝ) : ℂ) / 2 = -(m : ℂ) := hm have h2 : ((-R : ℝ) : ℂ) / 2 = ((-R / 2 : ℝ) : ℂ) := by push_cast; ring rw [h2] at h1 have h4 : ((-R / 2 : ℝ) : ℂ) = -(m : ℂ) := h1 have h5 : (-R / 2 : ℝ) = -(m : ℝ) := by exact_mod_cast h4 linarith [h5] ``` And hsR's statement: `s = ((-R : ℝ) : ℂ)` — but hsR is PROVED via Complex.ext_iff.mpr with `rw [h4, him]; simp` — h4 : s.re = -R: ext: s.re = ((-R:ℂ)).re and s.im = ((-R:ℂ)).im: simp proves ((−R:ℂ)).re = −R and im = 0 ✓ fine. Hmm — and hm : s/2 = −↑m: rw [hsR] at hm: hm : ((−R:ℂ))/2 = −↑m ✓ matches h1 ✓. 4. hG's `exact hpoles m h1` — hpoles takes (m : ℕ) and the proof s/2 ≠ −(m:ℂ) as an IMPLICIT?? hpoles : ∀ m : ℕ, s / 2 ≠ -(m : ℂ) — so `hpoles m h1 : False` ✓ then exact that — but the error shows "this term has type s / 2 = -↑m / Note: Expected a function because this term is being applied" — the `exact hpoles m h1` — hmm hpoles m h1 : False ✓ exact False-elim... `exact hpoles m h1` — hpoles m h1 is a proof of False: exact (hpoles m h1) should work via False.elim... Actually `exact h` with h : False works (False.elim is defeq-inferred). The error mentions "Expected a function" — because hpoles's TYPE: ∀ m : ℕ, s/2 ≠ −↑m — after h1 : s/2 = −↑m: hpoles m h1 : False ✓. Hmm — the error at 3591: `rw [show R / 2 - R / 2 = (0 : ℝ) by ring, abs_zero] at hgap'` — the hgap' from hgapInt (m : ℤ) with hcast + hm2: rw [hcast, ← hm2] at hgap': hgap' : 1/4 ≤ |R/2 − (m:ℝ)|: rw [← hm2] : hm2 : (m:ℝ) = R/2: ← hm2 rewrites R/2 → (m:ℝ)?? — rw [← hm2] at hgap' rewrites occurrences of hm2's RHS (R/2) by its LHS ((m:ℝ)) — hgap' has |R/2 − ↑m| — rw [← hm2] turns R/2 into ↑m: |↑m − ↑m|?? — NO: I want to turn ↑m into R/2: rw [hm2] (forward): ↑m → R/2: |R/2 − R/2| ✓. My code: `rw [hcast, ← hm2] at hgap'` — WRONG direction: should be `rw [hcast, hm2] at hgap'` — hcast : ((m:ℤ):ℝ) = (m:ℝ): hgap' : 1/4 ≤ |R/2 − ((m:ℤ):ℝ)|: rw [hcast] : |R/2 − (m:ℝ)|: rw [hm2] : |R/2 − R/2| ✓ then the show. Fix direction. Let me also double check hG's hpoles error — 3591's error is the rw direction one. The "Expected a function" note after — cascade. Fix the rw direction and the h1 forms.
Multiple form-mismatches. Applying fixes: 100000→200000 trans, left-assoc unification for the near-sum forms, hm2's cast forms, and the rw direction at hgap'.

Progress but more form mismatches: 1. Line 3532 (add_le_add hcap hnear): the calc step at 3525-3528 expects hnear's RHS in the NESTED form `32 * C0hat (...) * (3 * A0count * Real.log (...))` — but hnear now produces the LEFT-assoc. The calc step I wrote: `_ ≤ 200000 * (Real.log |s.im|) ^ 2 + 32 * C0hat (...) * (3 * A0count * Real.log (...)) := add_le_add hcap hnear` — the calc step's stated RHS has the nested form. Change the calc step's stated form to left-assoc: `200000 * (Real.log |s.im|) ^ 2 + 32 * C0hat (4 * (k:ℝ)+9/2) * (3 * A0count) * Real.log (3 * max ...)`. 2. Line 3584 (hm2's h1): `((-(R : ℝ)) : ℂ) / 2` vs hm's `↑(-R) / 2` — STILL mismatched: `(-(R : ℝ)) : ℂ` is neg-of-cast (−↑R) and hm has ↑(-R) (cast-of-neg). hsR : s = (-R : ℝ) — the `(-R : ℝ)` is −R in ℝ, then coerced: `↑(-R)`. So hm : (↑(-R))/2 = −↑m. My h1's type ascription `((-(R : ℝ)) : ℂ) / 2 = -(m : ℂ)` = -↑R/2 — mismatch. Fix: h1's form: `((-R : ℝ) : ℂ) / 2 = -(m : ℂ)` — `(-R : ℝ)` coerced: ((−R : ℝ) : ℂ) = ↑(-R) ✓ matches hm. (My parentheses: `((-R : ℝ) : ℂ)` — inside the parens: (-R : ℝ) is −R:ℝ; then the outer : ℂ coercion: ↑(-R) ✓.) The current text has `((-(R : ℝ)) : ℂ)` — neg INSIDE ℂ. Change to `((-R : ℝ) : ℂ)`. 3. Line 3595 (hpoles' im≠0 branch): `exact hm (by ...)` — hm : s / 2 = -(m : ℂ): the goal of hpoles is `s / 2 ≠ -(m:ℂ)` — wait hpoles : ∀ m, s/2 ≠ −↑m: the intro m hm gives hm : s/2 = −↑m and goal False. The branch: `· exact hm (by ...)` — hm is not a function! I wrote `exact hm (by ...)` treating hm as ¬(s/2 = −↑m)?? — NO: in hpoles, after `intro m hm`, hm : s / 2 = -(m : ℂ), goal : False. The by_cases him : s.im = 0 branch: real case handles. The else branch: I need to derive False from hm + im ≠ 0: hm gives (s/2).im = 0 (from −↑m's im = 0) contradicting (s/2).im = s.im/2 ≠ 0. My code: `· exact hm (by ...)` — nonsense (hm isn't a function). The by-block proves (s/2).im ≠ 0 and h4 : (s/2).im = 0: then `exact h1 h4` (h1 : (s/2).im ≠ 0, h4 : (s/2).im = 0 ⟹ False) — the `exact hm (...)` wrapper is wrong: just `exact h1 h4` after establishing h1, h3, h4: ``` · have h1 : (s / 2).im ≠ 0 := by have h2 : (s / 2).im = s.im / 2 := by simp rw [h2] exact div_ne_zero him (two_ne_zero : (2 : ℝ) ≠ 0) have h3 : (-(m : ℂ)).im = 0 := by rw [Complex.neg_im, Complex.natCast_im] have h4 : (s / 2).im = (-(m : ℂ)).im := congrArg Complex.im hm rw [h3] at h4 exact h1 h4 ``` Note div_ne_zero him (two_ne_zero) — for s.im/2 ≠ 0: div_ne_zero (hn : a ≠ 0) (hd : b ≠ 0)?? signature: `div_ne_zero (ha : a ≠ 0) (hb : b ≠ 0) : a / b ≠ 0` ✓ with (2 : ℝ) — hmm the division s.im/2 is in ℝ: two_ne_zero : (2 : ?) ≠ 0 — needs ℝ: (two_ne_zero : (2 : ℝ) ≠ 0) ✓. 4. Line 3624 (h3's type in hG?): cascade — let me fix the first three and recompile to see.
Three fixes: the calc-step form, h1's cast form, and the broken `exact hm (...)` branch.

Now I see the exact issue: hm : `↑(-R) / 2 = -↑m` (cast-of-neg: ↑(-R)) and my h2 : `-↑R / 2 = ↑(-R / 2)` — the cast NORMALIZATION: h2's LHS displays as `-↑R / 2` — so `((-R : ℝ) : ℂ) / 2` elaborates to `-↑R / 2`?? The h1 I ascribed `((-R : ℝ) : ℂ) / 2 = -(m : ℂ)` — it displays as `↑(-R) / 2 = -↑m` in the context (h1 : ↑(-R) / 2 = -↑m) — so the ascription `((-R : ℝ) : ℂ)` displays as ↑(-R)! And h2's `((-R : ℝ) : ℂ) / 2 = ((-R / 2 : ℝ) : ℂ)` displays as `-↑R / 2 = ↑(-R / 2)` — INCONSISTENT display — the two ascriptions elaborated DIFFERENTLY?! The h1's `((-R : ℝ) : ℂ)` became `↑(-R)` (cast-of-neg) but h2's `((-R : ℝ) : ℂ)/2` became `-↑R / 2` (neg-of-cast)... These are DEFEQ but not syntactically identical, and rw [h2] at h1 needs the pattern `-↑R / 2` in h1 which shows `↑(-R) / 2`. The push_cast in h2 normalized differently. Root cause: `(-R : ℝ) : ℂ` — the coercion `((−R : ℝ) : ℂ)` — Lean's coercion is `Complex.ofReal (−R)`?? but displays as `↑(-R)` — and in h2, push_cast rewrote it to `-↑R`. The robust fix: use congrArg Complex.re on hm directly (no h1/h2 chain): ``` have hm2 : (m : ℝ) = R / 2 := by have h1 := congrArg Complex.re hm -- h1 : (↑(-R) / 2).re = (-↑m).re have h2 : (↑(-R) / 2 : ℂ).re = -R / 2 := by simp have h3 : (-(m : ℂ)).re = -(m : ℝ) := by rw [Complex.neg_re, Complex.natCast_re] rw [h2, h3] at h1 -- h1 : -R / 2 = -(m : ℝ) linarith [h1] ``` h2 : (↑(-R)/2 : ℂ).re = −R/2: simp should compute: (↑(-R)).re = −R (ofReal_re) and the /2: ((↑(-R))/2).re = (↑(-R)).re/2?? — via Complex.div_re? for ofNat division: simp [Complex.div_re, Complex.ofReal_re, Complex.ofNat_re]... or just: simp — earlier `(s/2).re = s.re/2` was proved by `simp` (c-ii). Here (↑(-R)/2).re: = (↑(-R)).re/2 (the same simp lemmas) = (−R)/2 ✓ simp. Let me replace hm2's body with the congrArg route.
The cast forms are defeq-not-syntactic. Rerouting hm2 through `congrArg Complex.re` (no rewrite chains).

Replace with `by simp`. 2. Line 3623 (hG1's hre): `h3` has type `(1 - s.re) / 2 = -↑m` but expected `((1 - s) / 2).re = -↑m` — in hG1's hre block: ``` have hre : ((1 - s) / 2).re = -(m : ℝ) := by have h3 := congrArg Complex.re h2 rw [Complex.neg_re, Complex.natCast_re] at h3 have h4 : ((1 - s) / 2).re = (1 - s.re) / 2 := by simp [Complex.div_re] rw [h4] at h3 exact h3 ``` h3 after congrArg Complex.re h2 : ((1−s)/2).re = (−↑m).re — then rw [neg_re, natCast_re] at h3: h3 : ((1−s)/2).re = −(↑m).re?? wait — the RHS: (−↑m).re → neg_re: −((↑m).re) → natCast_re: −↑m ✓ so h3 : ((1−s)/2).re = −↑m ✓. Then rw [h4] at h3 — h4 : ((1−s)/2).re = (1−s.re)/2 — rewrites the LHS of h3: h3 : (1−s.re)/2 = −↑m — then `exact h3` — but hre's GOAL is `((1 - s) / 2).re = -(m : ℝ)` — h3 has the rewritten form (1−s.re)/2 — NOT the goal form! The rw [h4] at h3 changed h3's LHS away from the goal form. Fix: don't rw at h3 — instead convert the GOAL: ``` have hre : ((1 - s) / 2).re = -(m : ℝ) := by have h4 : ((1 - s) / 2).re = (1 - s.re) / 2 := by simp [Complex.div_re] rw [h4] have h3 := congrArg Complex.re h2 rw [Complex.neg_re, Complex.natCast_re] at h3 rw [h4] at h3 exact h3 ``` hmm — but the error shows h4 = `simp [Complex.div_re]` produced `(1 - s.re) / 2 = ...`?? The error: `h3 has type (1 - s.re) / 2 = -↑m but expected ((1 - s) / 2).re = -↑m` — so after my rw [h4] at h3, h3 became (1−s.re)/2-form, and exact h3 against goal ((1−s)/2).re-form fails. Restructure per above: rw [h4] at the GOAL first, then exact h3 (already in (1−s.re)/2-form). Wait — actually hold on: `simp [Complex.div_re]` for h4 : ((1 − s) / 2).re = (1 − s.re) / 2 — did simp prove it? If simp produced something odd... the error message is about the EXACT h3 mismatch — so h4 exists. Restructure: rw [h4] at the goal THEN exact h3. Hmm — but actually ((1−s)/2).re vs (1−s.re)/2 — also relevant for hpos etc. Let me fix hG1's hre block by reordering. 3. Line 3636 "No goals" — cascade. 4. Line 3666 — let me see after fixing. Also the 242 n-unused warning (dirichletC2_nonneg's `fun n => norm_nonneg _` — the n is unused: change to `fun _ => norm_nonneg _`... wait the warning is at 242:19 — dirichletC2_nonneg's lambda binder — hmm `fun n => norm_nonneg _` — n used as norm's arg? `norm_nonneg _` — the _ is inferred — n unused ✓ change to `fun _ => norm_nonneg _`.

`riemannZeta_ne_zero_of_one_le_re : ∀ ⦃s : ℂ⦄, 1 ≤ s.re → riemannZeta s ≠ 0` — only ONE hypothesis (no s ≠ 1 — Mathlib's is unconditional for re ≥ 1, ζ(1) handled via the junk/∞?). So the `apply` produced ONE goal (re) — the second bullet `· intro h` has no goal. Fix: remove the second bullet entirely and the unused hζ1 branch: ``` have hζ1 : riemannZeta (1 - s) ≠ 0 := by apply riemannZeta_ne_zero_of_one_le_re have h1 : (1 - s).re = 1 - s.re := by simp rw [h1] linarith [hreg2] ``` Also fix region-iii's h5 with the right combinator, and the div_re simp warnings.
`riemannZeta_ne_zero_of_one_le_re` takes only the re hypothesis — removing the phantom second bullet, fixing h5's combinator, and the simp warnings.

Two errors: 1. Line 3797 (h2c): after `rw [h3]`, the goal became `1 * C0hat (...) ≤ A0count * (1 * C0hat (...))` — rw [h3] rewrote Ĉ₀ to 1·Ĉ₀ EVERYWHERE (both sides). Fix: don't rw — use calc: ``` have h2c : C0hat (4 * (k : ℝ) + 9 / 2) ≤ A0count * C0hat (4 * (k : ℝ) + 9 / 2) := calc C0hat (4 * (k : ℝ) + 9 / 2) = 1 * C0hat (4 * (k : ℝ) + 9 / 2) := by ring _ ≤ A0count * C0hat (4 * (k : ℝ) + 9 / 2) := mul_le_mul_of_nonneg_right A0count_ge_one hĈpos.le ``` Same for the Fexpr h2c (the earlier one I already fixed — check if it has the same bug: yes — same pattern: `rw [h3]; exact mul_le_mul_of_nonneg_right A0count_ge_one hĈR2pos.le` — same rw-everywhere issue: fix with calc too). 2. Line 3861 (hchain's final step): the last `apply add_le_add_right` then `exact norm_sub_le _ _` — the goal at that point: `‖logDeriv ζ s − seriesFun s‖ + ‖1/s‖ + ‖1/(s−1)‖ + ‖logπ/2‖ + ‖ψ/2‖ ≤ ‖logDeriv ζ s‖ + ‖seriesFun s‖ + ‖1/s‖ + ...` — this needs add_le_add on the FIRST component (‖X−Y‖ ≤ ‖X‖+‖Y‖), NOT add_le_add_right (which adds on the LEFT of each side?? add_le_add_right (h : b ≤ c) (a) : a + b ≤ a + c — adds a on the LEFT ✓ — the goal: (‖X−Y‖ + ‖1/s‖ + ‖1/(s−1)‖ + ‖logπ/2‖) + ‖ψ/2‖ ≤ ... — my nested `apply add_le_add_right` four times then norm_sub_le: each add_le_add_right strips one trailing +term... the mismatch: the LAST apply add_le_add_right's expected form `?a + ?b ≤ ?a + ?c` vs the goal `‖X−Y‖ + ‖1/s‖ + ‖1/(s−1)‖ + ‖logπ/2‖ + ‖ψ/2‖ ≤ ‖X‖ + ‖Y‖ + ‖1/s‖ + ...` — with ?a := ‖X−Y‖ + ‖1/s‖ + ‖1/(s−1)‖ + ‖logπ/2‖ + ‖ψ/2‖... hmm — after three add_le_add_right applications, the goal should be `‖X−Y‖ + ‖1/s‖ ≤ ‖X‖ + ‖Y‖ + ‖1/s‖`?? Let me re-think the chain structure. The expression tree: ((((X−S) + A) + B) − C) + D where X = logDeriv, S = seriesFun, A = 1/s, B = 1/(s−1), C = logπ/2, D = ψ/2. Goal: ‖((((X−S)+A)+B)−C)+D‖ ≤ ‖X‖+‖S‖+A'+B'+C'+D' (with A' = ‖1/s‖ etc). Step 1: ≤ ‖(((X−S)+A)+B)−C‖ + D' (norm_add_le) — that's what I did. Step 2: ≤ ‖((X−S)+A)+B‖ + C' + D' (norm_sub_le on the first part: ‖P−C‖ ≤ ‖P‖+‖C‖): add_le_add_right (norm_sub_le) _ ✓. Step 3: ‖((X−S)+A)+B‖ ≤ ‖(X−S)+A‖ + B' (norm_add_le) ✓. Step 4: ‖(X−S)+A‖ ≤ ‖X−S‖ + A' (norm_add_le) ✓. Step 5: ‖X−S‖ ≤ ‖X‖ + ‖S‖ (norm_sub_le) — the final goal after 4 add_le_add_right: `‖X−S‖ + A' + B' + C' + D' ≤ ‖X‖ + ‖S‖ + A' + B' + C' + D'` — need add_le_add_right (norm_sub_le _ _) (A'+B'+C'+D')?? — the goal after 4 strips: hmm — each `add_le_add_right h _` adds a on the LEFT: add_le_add_right (h : b ≤ c) (a) : a + b ≤ a + c. The calc step form: `_ ≤ LHS4 + D' := add_le_add_right (norm_add_le _ _) _` — wait — my calc steps used add_le_add_right to transform: e.g. step: `_ ≤ ‖(X−S)+A‖ + B' + C' + D' := add_le_add_right (add_le_add_right (norm_add_le _ _) _) _` — these transform the RIGHTMOST sum: ‖((X−S)+A)+B‖ + (C'+D')?? — the associativity: the stated step forms in my calc: `_ ≤ ‖logDeriv riemannZeta s - seriesFun s‖ + ‖(1 : ℂ) / s‖ + ‖(1 : ℂ) / (s - 1)‖ + ‖(Real.log Real.pi : ℂ) / 2‖ + ‖Complex.digamma (s / 2) / 2‖` — flat left-assoc sums ✓ — the transformations: each step peels one level: from ‖((((X−S)+A)+B)−C)+D‖ ≤ [step1] ‖(((X−S)+A)+B)−C‖+‖D‖ ≤ [step2: norm_sub_le on the first] (‖((X−S)+A)+B‖+‖C‖)+‖D‖ — hmm — step2's add_le_add_right (norm_sub_le _ _) _ : (‖P−C‖ ≤ ‖P‖+‖C‖) with a := ‖D‖: ‖P−C‖+‖D‖ ≤ (‖P‖+‖C‖)+‖D‖ ✓. Step3: goal-form: ‖((X−S)+A)+B‖+‖C‖+‖D‖ ≤ (‖(X−S)+A‖+‖B‖)+‖C‖+‖D‖: add_le_add_right (add_le_add_right (norm_add_le _ _) _) _: inner: ‖Q+B‖+‖C‖ ≤ (‖Q‖+‖B‖)+‖C‖ ✓ then outer +‖D‖ ✓. Step4: ‖(X−S)+A‖+‖B‖+‖C‖+‖D‖ ≤ (‖X−S‖+‖A‖)+‖B‖+‖C‖+‖D‖ ✓ add_le_add_right³. Step5 (LAST): goal: ‖X−S‖+‖A‖+‖B‖+‖C‖+‖D‖ ≤ (‖X‖+‖S‖)+‖A‖+‖B‖+‖C‖+‖D‖ — my final stated form: `‖logDeriv riemannZeta s‖ + ‖seriesFun s‖ + ‖(1 : ℂ) / s‖ + ...` — flat: ‖X‖+‖S‖+A'+B'+C'+D' left-assoc ✓ the step needs: add_le_add_right (add_le_add_right (add_le_add_right (add_le_add_right (norm_sub_le _ _) _) _) _) _?? — the norm_sub_le transforms ‖X−S‖ → ‖X‖+‖S‖ at the HEAD of the sum: (‖X−S‖)+A'+B'+C'+D' → (‖X‖+‖S‖)+A'+B'+C'+D': the head replacement with four trailing terms: add_le_add_right (norm_sub_le _ _) (‖A‖+‖B‖+‖C‖+‖D‖)?? — add_le_add_right h a : a + b ≤ a + c with b := ‖X−S‖, c := ‖X‖+‖S‖, a := the REST — but the rest is on the RIGHT of the head: ‖X−S‖+A'+B'+C'+D' = ‖X−S‖ + (A'+B'+C'+D')?? NO — left-assoc: ((((‖X−S‖+A')+B')+C')+D') — the head ‖X−S‖ is the LEFTMOST; transforming it needs add_le_add on the LEFT factor of the INNERMOST sum: (((‖X−S‖+A')+B')+C')+D' — to replace ‖X−S‖ with ‖X‖+‖S‖: apply add_le_add_right 4 times with h := norm_sub_le: add_le_add_right (h : b ≤ c) (a) : a + b ≤ a + c — with b := ‖X−S‖?? no: the innermost sum is ‖X−S‖+A': transform to (‖X‖+‖S‖)+A' — that's add_le_add (norm_sub_le) (le_refl A') hmm — add_le_add_right h a gives a+b ≤ a+c — the a is on the LEFT. For ‖X−S‖+A' ≤ (‖X‖+‖S‖)+A': need b := ‖X−S‖ → c := ‖X‖+‖S‖ with a := A' on the LEFT: A' + ‖X−S‖ — WRONG SIDE. add_le_add_right is for modifying the RIGHT addend. To modify the LEFT addend: add_le_add_left h a : b + a ≤ c + a ✓ — the session-025 gotcha: "add_le_add_left/right are swapped vs classic"! In THIS Mathlib: add_le_add_left (h : b ≤ c) (a) : b + a ≤ c + a?? or a+b ≤ a+c? From the earlier error in 3a: `add_le_add_left (mul_le_mul_of_nonneg_left hΔle ...) ?m` produced `0.532*Δ1 + ?m ≤ 0.532*Δ2 + ?m` — i.e., add_le_add_left h a : b + a ≤ c + a in this Mathlib (modifies the LEFT addend b→c with a on the RIGHT). And add_le_add_right h a : a + b ≤ a + c (modifies RIGHT). So the step: ‖X−S‖ + A' ≤ (‖X‖+‖S‖) + A' = add_le_add_left (norm_sub_le _ _) A' ✓!! So my LAST step should be add_le_add_LEFT (norm_sub_le _ _) applied 4 times (one per trailing term): ``` _ ≤ ‖logDeriv riemannZeta s‖ + ‖seriesFun s‖ + ‖(1 : ℂ) / s‖ + ‖(1 : ℂ) / (s - 1)‖ + ‖(Real.log Real.pi : ℂ) / 2‖ + ‖Complex.digamma (s / 2) / 2‖ := by apply add_le_add_right apply add_le_add_right apply add_le_add_right apply add_le_add_right exact norm_sub_le _ _ ``` With add_le_add_right h a : a + b ≤ a + c — peeling: the goal at the last apply: `?a + ?b ≤ ?a + ?c` vs `‖X−S‖+‖A‖+‖B‖+‖C‖+‖D‖ ≤ ‖X‖+‖S‖+‖A‖+‖B‖+‖C‖+‖D‖` — hmm — add_le_add_right unifies a + b with LHS: a := ‖X−S‖+‖A‖+‖B‖+‖C‖, b := ‖D‖: then c should satisfy ‖D‖ = c: the RHS must be a + c = same-a + c: RHS: ‖X‖+‖S‖+‖A‖+‖B‖+‖C‖+‖D‖ — a ≠ that prefix (prefix differs: ‖X−S‖ vs ‖X‖+‖S‖) — FAILS. So peeling with add_le_add_right can't change the LEFTMOST factor. Correct final step: transform the head with add_le_add_LEFT four times?? — add_le_add_left h a : b + a ≤ c + a (this Mathlib): goal: ‖X−S‖+A'+B'+C'+D' ≤ (‖X‖+‖S‖)+A'+B'+C'+D': the head ‖X−S‖ is inside the nesting: ((((h+A')+B')+C')+D'): to change h → h': apply add_le_add_right (a := D'): changes the RIGHTMOST: (((h+A')+B')+C')+D' ≤ ?+D' with ? := ((h+A')+B')+C' — hmm — add_le_add_right h' a : a + b ≤ a + c: unifies a+b with ((((h+A')+B')+C')+D'): a := (((h+A')+B')+C'), b := D' — no, we want to change the HEAD not D'. So: the right approach: each `apply add_le_add_right` peels the RHS structure: goal := X₁ + t ≤ Y₁ + t where t is the last term and X₁ ≤ Y₁ is the sub-goal: with the FINAL sub-goal ‖X−S‖ + A' ≤ (‖X‖+‖S‖) + A' — then the LAST tactic must be add_le_add_LEFT (norm_sub_le _ _) A' — modifying the left addend. Wait — which one is "left" in this Mathlib: add_le_add_left h a : b + a ≤ c + a (per the 3a evidence: produced `0.532*Δ1 + ?m ≤ 0.532*Δ2 + ?m` — the changed part is the FIRST addend, a is appended on the RIGHT). So final step: `exact add_le_add_left (norm_sub_le _ _) _` with the trailing-term argument — after 4 `apply add_le_add_right` peels, the goal is ‖X−S‖ + A' ≤ (‖X‖+‖S‖) + A' — `exact add_le_add_left (norm_sub_le _ _) _` ✓ (a := ‖(1:ℂ)/s‖ inferred). Hmm wait — but then steps 2-4 of my calc (the add_le_add_right (norm_...) _ steps) — are THOSE right? Step: `_ ≤ ‖(X−S)+A‖ + ‖B‖ + ‖C‖ + ‖D‖` from `‖((X−S)+A)+B‖ + ‖C‖ + ‖D‖`: transform ((X−S)+A)+B → (X−S)+A+B: peeling: the stated RHS form is flat left-assoc ✓: the transformations needed: at each step the change is in the LEFT-addend of the current innermost sum — SAME ISSUE at every step!! E.g. step from `‖P−C‖ + ‖D‖` to `(‖P‖+‖C‖) + ‖D‖` — that's add_le_add_LEFT (norm_sub_le) ‖D‖ (the changed part is the left addend ‖P−C‖ → ‖P‖+‖C‖)!! So ALL my steps 2-5 should use add_le_add_left (this-Mathlib-swapped sense) not add_le_add_right!! Hold on — but steps 2-4 compiled?? The error was only at the LAST apply (3861). Let me recheck the error: "could not unify the conclusion of @add_le_add_right ?a + ?b ≤ ?a + ?c with the goal ‖X−S‖+A'+B'+C'+D' ≤ ‖X‖+‖S‖+A'+B'+C'+D'" — the failure is at the step transforming ‖X−S‖... — hmm but wait: my calc's earlier steps used add_le_add_right with norm_sub_le/norm_add_le — let me recheck step 2's stated forms: `_ ≤ ‖logDeriv riemannZeta s - seriesFun s + 1 / s + 1 / (s - 1)‖ + ‖(Real.log Real.pi : ℂ) / 2‖ + ‖Complex.digamma (s / 2) / 2‖ := add_le_add_right (norm_sub_le _ _) _` — the PREVIOUS step's RHS: `‖logDeriv ζ s − seriesFun s + 1/s + 1/(s−1) − logπ/2‖ + ‖ψ/2‖` — and this step's RHS: `‖logDeriv ζ s − seriesFun s + 1/s + 1/(s−1)‖ + ‖logπ/2‖ + ‖ψ/2‖` — the change: ‖P−C‖ → ‖P‖+‖C‖ in the LEFT addend ✓ add_le_add_right h a : a+b ≤ a+c — unify a+b with (‖P−C‖+‖ψ/2‖): a := ‖P−C‖, b := ‖ψ/2‖; a+c with (‖P‖+‖C‖+‖ψ/2‖): c := ‖ψ/2‖ — so h : ‖ψ/2‖ ≤ ‖ψ/2‖?! That's le_refl not norm_sub_le!! But the error wasn't raised at step 2... hmm — because `add_le_add_right (norm_sub_le _ _) _` unified b := ‖P−C‖-with-... — add_le_add_right (h : b ≤ c) (a) : a + b ≤ a + c — with h := norm_sub_le _ _ : ‖?x − ?y‖ ≤ ‖?x‖+‖?y‖: unify a + (‖?x‖+‖?y‖)... wait h gives the RELATION b ≤ c with b := ‖?x−?y‖?? no — norm_sub_le : ‖x−y‖ ≤ ‖x‖+‖y‖: so b := ‖?x−?y‖, c := ‖?x‖+‖?y‖: the conclusion a+b ≤ a+c: a + ‖?x−?y‖ ≤ a + (‖?x‖+‖?y‖): unify with LHS ‖P−C‖+‖ψ/2‖: a + ‖?x−?y‖ = ‖P−C‖+‖ψ/2‖ — so a := ‖P−C‖ and ‖?x−?y‖ := ‖ψ/2‖ — MISMATCH (?x−?y can't unify with a norm). UNLESS the elaborator tried a := ‖ψ/2‖... a + ‖?x−?y‖ = ‖P−C‖+‖ψ/2‖: first-addend must match: a := ‖P−C‖ ✓ then ‖?x−?y‖ = ‖ψ/2‖ ✗. Hmm — so how did steps 2-4 elaborate at all? Maybe they DIDN'T and the errors are all at those positions but only the FIRST is shown (3861 — which is... the last apply in the final step's `apply add_le_add_right × 4; exact norm_sub_le _ _` sequence). Since Lean elaborates tactic blocks and reports errors per-tactic, earlier steps may have elaborated OK by luck: let me recheck step 2: the PREVIOUS step's RHS (step 1's): `‖logDeriv ζ s − seriesFun s + 1/s + 1/(s−1) − logπ/2‖ + ‖ψ/2‖` and step 2's RHS: `‖logDeriv ζ s − seriesFun s + 1/s + 1/(s−1)‖ + ‖logπ/2‖ + ‖ψ/2‖` — change: inside the first factor, ‖P−C‖ → ‖P‖+‖C‖ — but the first factor is itself `‖...−logπ/2‖` — as an addend: `‖P−C‖ + ‖D‖` where the OUTER expression is ‖P−C‖+‖D‖: to transform the FIRST addend: add_le_add_left (norm_sub_le _ _) ‖D‖ — modifies LEFT addend ✓. So step 2 should be add_le_add_left. But the error was only at 3861?? — the elaborator processes ALL tactics; with multiple errors it shows several — the head -40 cut off everything below. Likely ALL four steps have the same issue but only the first-position error got displayed... Actually errors ARE reported per tactic position — the head -40 showed only the 3861 one (plus 3797). Maybe steps 2-4 unified by luck of metavariable assignment?? — e.g. step 2: add_le_add_right (norm_sub_le _ _) _: a + ‖?x−?y‖ ≤ a + (‖?x‖+‖?y‖) against `‖logDeriv...− logπ/2‖ + ‖ψ/2‖ ≤ ‖logDeriv...‖ + ‖logπ/2‖ + ‖ψ/2‖`: hmm the RHS's associativity: (‖...‖ + ‖logπ/2‖) + ‖ψ/2‖: a + c := (‖...‖+‖logπ/2‖) + ‖ψ/2‖: a := ‖...‖+‖logπ/2‖?? and LHS a + ‖?x−?y‖ := ‖...−logπ/2‖+‖ψ/2‖: a must equal both: ‖...−logπ/2‖ vs ‖...‖+‖logπ/2‖ — no. So it can't have worked — the errors at steps 2-4 must exist but got cut by head -40. Let me restructure the whole hchain to avoid the left/right confusion: use a single `calc` with explicit steps each proved by a dedicated have, or better — use gcongr! `gcongr` handles monotone-add chains: the whole chain: ‖((((X−S)+A)+B)−C)+D‖ ≤ ‖X‖+‖S‖+A'+B'+C'+D': gcongr should decompose: ‖?‖ ≤ ‖?‖ with norm_sub_le/norm_add_le as its lemmas?? — gcongr uses tagged lemmas; norm_add_le/norm_sub_le aren't gcongr-tagged by default. Alternative robust: prove the 6-term bound by repeated have + linarith: ``` have hc1 : ‖Fexpr s‖ ≤ ‖logDeriv riemannZeta s - seriesFun s + 1/s + 1/(s-1) - (logπ)/2‖ + ‖Complex.digamma (s/2)/2‖ := by rw [Fexpr]; exact norm_add_le _ _ have hc2 : ‖logDeriv riemannZeta s - seriesFun s + 1/s + 1/(s-1) - (Real.log Real.pi : ℂ)/2‖ ≤ ‖logDeriv riemannZeta s - seriesFun s + 1/s + 1/(s-1)‖ + ‖(Real.log Real.pi : ℂ)/2‖ := norm_sub_le _ _ have hc3 : ... ≤ ‖logDeriv ζ s - seriesFun s + 1/s‖ + ‖(1:ℂ)/(s-1)‖ := norm_add_le _ _ have hc4 : ... ≤ ‖logDeriv ζ s - seriesFun s‖ + ‖(1:ℂ)/s‖ := norm_add_le _ _ have hc5 : ‖logDeriv riemannZeta s - seriesFun s‖ ≤ ‖logDeriv riemannZeta s‖ + ‖seriesFun s‖ := norm_sub_le _ _ -- then combine by linarith linarith [hc1, hc2, hc3, hc4, hc5, hser2?, ...] ``` with each norm_ lemma applied directly to the expression — no add_le_add_* at all, and linarith does the sum bookkeeping (norm terms as atoms ✓ same atoms everywhere since the sub-expressions are textual). MUCH more robust. The hchain's goal: ‖Fexpr‖ ≤ [6 atoms] — from hc1..hc5 by linarith ✓. Let me rewrite hchain that way.
The add_le_add_left/right swap strikes the whole chain. Restructuring hchain to per-step `norm_add_le/norm_sub_le` haves + linarith (no add_le_add at all).

The final linarith (hbig's `linarith [hser2, hld2, hψ2, h1s, h1s1, hlogpi, h1, lowZeroConst_nonneg, dirichletC2_nonneg]` at ~3921) failed. The issue: hbig's statement — its GOAL is `‖logDeriv ζ s‖ + ‖seriesFun s‖ + ... ≤ 2·lowZeroConst + dirichletC2 + 400000·...` — and I have hser2 (‖seriesFun‖ ≤ ...), hld2 (‖logDeriv‖ ≤ ...), hψ2 (‖ψ/2‖ ≤ 31+12L), h1s, h1s1, hlogpi, h1 (the absorption 2900X + (200000L² + 300X) + ((31+12L)+2) ≤ 400000X). The linarith needs to combine: LHS = sum of the 6 norms ≤ [hser2's RHS] + [hld2's RHS] + 1 + 1 + 1 + [hψ2's RHS] = 2·lowZeroConst + 2900X + dirichletC2 + 200000L² + 300X + 3 + 31+12L = 2·lowZeroConst + dirichletC2 + (2900X + 200000L² + 300X + 34 + 12L). And h1 says 2900X + (200000L² + 300X) + ((31+12L)+2) ≤ 400000X: i.e. 2900X+200000L²+300X+33+12L ≤ 400000X. My sum has 34+12L (extra 1 from... let me recount: h1s : ‖1/s‖ ≤ 1; h1s1 : ‖1/(s−1)‖ ≤ 1; hlogpi : ‖logπ/2‖ ≤ 1: THREE ones: total +3. hψ2 : 31+12L. So non-X part: 31+12L+3 = 34+12L. h1's form: (31+12·L)+2 = 33+12L. MISMATCH by 1!! h1 as stated: `((31 + 12 * Real.log R) + 2)` — but the actual sum needs +3 (three ones). Fix h1's +2 → +3: `2900X + (200000L² + 300X) + ((31+12L) + 3) ≤ 400000X` — and the nlinarith for h1 must absorb 34+12L: 400000X − 3200X = 396800X ≥ 200000L² + 34 + 12L: X = A₀Ĉ₀L² ≥ 162: 200000L² ≤ 100000·2·... — the h5 inside h1 handles 200000·L² ≤ 100000·X (X ≥ 2L² ✓): remaining: 396800X − 100000X = 296800X ≥ 34+12L ⟸ 34+12L ≤ 34·X/162·... 34+12L ≤ 46·L·... ≤ 46·X·...

OK the nlinarith inside h1 already proved the +2 version (33+12L); the +3 version (34+12L) — the slack is enormous (h4 : 1 ≤ X and h5's 100000X headroom and h2 : 2 ≤ A₀Ĉ₀(R+2) and h3 : 81 ≤ L²): 34+12L vs the budget 400000X−3200X−100000X = 296800X ≥ 296800 ≥ 34+12L ⟸ 12L ≤ 296766 and L ≤ ... we don't have a numeric cap on L!

So the nlinarith needs: h5 (200000L² ≤ 100000X), hLL (L ≤ L²), h3 (81 ≤ L²), h2 (2 ≤ A₀Ĉ₀(R+2)), and nonnegs. Give those: ``` have hLL : Real.log R ≤ (Real.log R) ^ 2 := by nlinarith [hlogR] have h1 : 2900 * A0count * C0hat (R + 2) * (Real.log R) ^ 2 + (200000 * (Real.log R) ^ 2 + 300 * A0count * C0hat (R + 2) * (Real.log R) ^ 2) + ((31 + 12 * Real.log R) + 3) ≤ 400000 * A0count * C0hat (R + 2) * (Real.log R) ^ 2 := by have h2 : (2 : ℝ) ≤ A0count * C0hat (R + 2) := (as fixed) have h3 : (81 : ℝ) ≤ (Real.log R) ^ 2 := by nlinarith [hlogR, hlogRnn] have h4 : (1 : ℝ) ≤ A0count * C0hat (R + 2) * (Real.log R) ^ 2 := by nlinarith [h2, h3, hA0, hĈR2pos] have h5 : 200000 * (Real.log R) ^ 2 ≤ 100000 * A0count * C0hat (R + 2) * (Real.log R) ^ 2 := by nlinarith [h2, pow_two_nonneg (Real.log R)] nlinarith [h5, h4, h2, h3, hLL, hlogRnn, hA0, hĈR2pos] ``` Check nlinarith can finish: goal: 3200X + 200000L² + 34+12L ≤ 400000X ⟺ 200000L²+34+12L ≤ 396800X.

Actually the X ≥ 2L² fact: from h2 (2 ≤ A₀Ĉ₀) and L² ≥ 0: (A₀Ĉ₀−2)·L² ≥ 0 ⟹ A₀Ĉ₀L² ≥ 2L² ✓ — nlinarith product of (h2) with (L² ≥ 0) ✓. Let me apply: fix h1's +2 → +3 with the hLL addition.
The final absorption is off by one (three `1`s, not two). Fixing h1 with the L ≤ L² hint.

Compiles clean except `hRhi` unused in `logDeriv_circle_le` — wait no, the warning is at 3807 — that's `Fexpr_circle_le`'s hRhi! Fexpr_circle_le's signature has hRhi : R ≤ 4k+3 — is it used? Looking at the proof: hĈR2 uses `C0hat_mono (1 ≤ 4k+9/2) (4k+9/2 ≤ R+2)` — the latter from hRlo (4k+5/2 ≤ R ⟹ 4k+9/2 ≤ R+2 ✓) — hRhi not used! But hRhi is part of the gap-circle data — keep the API uniform (the caller has it from exists_gapCircle_radius). Prefix with underscore: `_hRhi`. Hmm — or keep for API and accept the warning? The project standard: zero warnings preferred (earlier I removed unused args). But hRhi is genuinely part of the natural hypothesis pack — the FINAL capstone will apply Fexpr_circle_le with the full gap-circle data. Options: (a) rename to _hRhi (callers can still pass it positionally — Lean doesn't care about the name for explicit args); (b) drop it. The 5e-v-d caller will have hRhi from exists_gapCircle_radius anyway and can pass or not. Rename to _hRhi — keeps the signature shape (useful for the caller, documents the full hypothesis pack) while silencing the warning.
Clean except unused `hRhi` in `Fexpr_circle_le` — underscore-prefix it (keeps the hypothesis-pack shape for the 5e-v-d caller).

Committed. Now session closure: journal-033, STATE.md, NGUYEN.md, db, final commit. Let me also check the time — the session has been long; per §8.5 I should finish the closure cleanly (no user break prompt needed since the user said "let's continue next session" and the closure is quick). Let me write journal-033.
Committed. Now session closure artifacts.

Now update STATE.md (header + the 5e-v progress paragraph + NEXT ACTION → 5e-v-d), NGUYEN.md (checklist line + session log), db, and commit. For 5e-v-d I need to think about the squeeze details for the NEXT ACTION: - Gentire entire (gentire_analyticAt_and_eq : (∀ s, AnalyticAt ℂ Gentire s) ∧ (∀ s good, Gentire s = Fexpr s)). - On the circle |s| = R: every s is a GOOD point (not badPoint): badPoint s = nontrivial ∨ s = 0 ∨ s = 1 ∨ ∃ n ≥ 1, s = −2n: on the circle: not nontrivial (3a), ≠ 0 (‖s‖ = R > 0), ≠ 1 (‖s‖ = R > 1), ≠ −2n (re arbitrary: −2n real: ‖−2n‖ = 2n = R: excluded when R/2 ∉ ℤ?? wait −2n: ‖s‖ = R = 2n ⟹ R/2 = n ∈ ℤ — excluded by hgapInt! ✓). So Gentire s = Fexpr s on the circle ⟹ ‖Gentire s‖ ≤ the Fexpr bound on the sphere. - MapsTo: DifferentiableOn ℂ Gentire (ball 0 R) (from AnalyticAt ∀ s) + MapsTo (sphere 0 R) into closedBall (Gentire 0) (2·lowZeroConst + dirichletC2 + 400000·A₀·Ĉ₀(R+2)·(log R)² + ‖Gentire 0‖) — via the max-modulus: Zeta23's AnalyticOn.norm_le_of_norm_le_on_sphere (journal-030 mentions it). - Complex.dist_le_div_mul_dist_of_mapsTo_ball : dist (f z) (f 0) ≤ (R₂/R)·dist z 0·... the Schwarz lemma form: for f analytic on ball 0 R mapping into ball (f 0) R₂: dist (f z) (f 0) ≤ (R₂/R)·‖z‖·... need the exact Mathlib form: `Complex.dist_le_div_mul_dist_of_mapsTo_ball (hd : DifferentiableOn ℂ f (ball 0 R)) (hm : MapsTo f (ball 0 R) (ball (f 0) R₂)) (hz : ‖z‖ < R) : dist (f z) (f 0) ≤ R₂ / R * ‖z‖`? hmm — the Schwarz lemma variant: mapsTo into ball (f 0) R₂ (OPEN ball) — our bound is closedBall — bridge via ball ⊆ closedBall and R₂ < R₂' (take R₂' := R₂+1). - The ratio: R₂(R)/R = [2·lowZeroConst + dirichletC2 + 400000·A₀·Ĉ₀(R+2)·(log R)² + ‖Gentire 0‖]/R — need this → 0 as k → ∞ (R ≈ 4k): Ĉ₀(R+2) = 0.433·log(R+4) + 0.886·loglog(R+4) + 2.9 ≤ C·log R: so R₂(R) ≤ C'·(log R)³-ish: (log R)³/R → 0: need to FORMALIZE: for fixed z₀, pick k large enough that R > the crossover where R₂(R) < ε·R·... — actually the squeeze: dist (Gentire z₀) (Gentire 0) ≤ R₂(R_k)/R_k·|z₀| for EVERY k ≥ max(k₀, |z₀|): the RHS → 0: formalize via Tendsto: R₂(R_k)/R_k → 0 ⟹ dist = 0 (by le_of_tendsto or a direct Archimedean argument: dist ≥ 0 and dist ≤ ε for all ε > 0 ⟹ dist = 0). The cleanest: show ∀ ε > 0, ∃ k, R₂(R_k)/R_k·|z₀| < ε: R₂(R)/R ≤ C·(log R)³/R → 0: need (log R)³/R → 0 formalized — hmmm: (log R)³/R ≤ R^{3/4}·64/R·... : log R ≤ 4·R^{1/4} (Real.log_le_rpow or via exp: log x ≤ x^{1/4}·4 ⟸ log(x⁴) = 4 log x ≤ x hmm log y ≤ y: log x = (1/4)·log(x⁴)·... log(x⁴) = 4 log x: and log(x⁴) ≤ x⁴−1 < x⁴: so 4 log x < x⁴ ⟹ log x < x⁴/4 — that's log x ≤ x⁴/4 not what I want. For (log R)³/R → 0: log R ≤ 4·R^{1/4}/1 hmm: log R = 4·log(R^{1/4}) ≤ 4·(R^{1/4}−1) ≤ 4·R^{1/4}: so (log R)³ ≤ 64·R^{3/4}: R₂/R ≤ C·64·R^{3/4}/R = 64C·R^{−1/4} → 0. With R ≈ 4k: R^{−1/4} → 0: for ε: need R ≥ (64C/ε)⁴·|z₀|⁴-ish — choose k large. So the squeeze: dist (Gentire z₀) (Gentire 0) ≤ 64C·|z₀|·R_k^{−1/4} for all k ≥ k₀: and R_k ≥ 4k ⟹ → 0: conclude dist = 0 by `eq_of_forall_le_of_forall_lt...`? The cleanest formalization: dist ≤ 0 via: by_contra dist > 0: choose k with 4k > (64C·|z₀|/dist)⁴: then 64C·|z₀|·R^{−1/4} < dist ✗. Needs: R^{1/4} as Real.rpow or sqrt∘sqrt — use Real.sqrt: R^{1/4} = √(√R): (log R)³ ≤ 64·(√(√R))³·... hmm rpow is cleaner: Real.log_le_rpow (hx : 1 ≤ x) (hr : 0 < r) : log x ≤ r⁻¹·x^r?? There IS `Real.log_le_rpow (x : ℝ) (hx : 1 ≤ x) (r : ℝ) (hr : 0 < r) : Real.log x ≤ r⁻¹ * x ^ r`?? I recall `Real.log_le_rpow : 1 ≤ x → 0 < r → log x ≤ r⁻¹ * x^r`. Then log R ≤ 4·R^{1/4} (r = 1/4, r⁻¹ = 4 ✓): (log R)³ ≤ 64·(R^{1/4})³ = 64·R^{3/4}: (R^{1/4})³ = R^{3/4} (rpow_nat_inv_pow... rpow arithmetic). And Ĉ₀(R+2) ≤ 5·log R for R large (0.433·log(R+4)+0.886·loglog(R+4)+2.9: log(R+4) ≤ 2·log R (R+4 ≤ R² for R ≥ 2·... R+4 ≤ R² ⟺ R²−R−4 ≥ 0 ✓ R ≥ 3: log(R+4) ≤ 2 log R; loglog(R+4) ≤ log(2 log R) = log2 + loglog R ≤ 1 + log R·... loglog R ≤ log R: so Ĉ₀ ≤ 0.433·2L + 0.886·(1+L) + 2.9 ≤ 0.866L+0.886L+0.886+2.9 ≤ 1.8L+4 ≤ 5L (L ≥ 1). So R₂(R) ≤ 2·lowZeroConst + dirichletC2 + 400000·A₀·5L·L² + ‖Gentire 0‖ = C₀' + 2·10⁶·A₀·L³ (symbolic constants). R₂(R)/R ≤ (C₀' + 2·10⁶·A₀·L³)/R ≤ C₀'·... for the ratio → 0: (C₀' + C₁·L³)/R: split: C₀'/R ≤ C₀'/R and C₁·L³/R ≤ C₁·64·R^{3/4}/R = 64·C₁·R^{−1/4}: both → 0. The capstone then: for z₀ any good point: Gentire z₀ = Gentire 0 (dist = 0) ⟹ Fexpr z₀ = Gentire 0 =: B (the constant!) — wait: Gentire ≡ Gentire 0 means Gentire is the CONSTANT function Gentire 0 — call it B: then at good s: logDeriv ζ s = Fexpr s = B ⟹ logDeriv ζ s = B + seriesFun s − 1/s − 1/(s−1) + (log π)/2 − ψ(s/2)/2 from Fexpr's definition ✓ the partialFraction_identity. Formal pieces for 5e-v-d: 1. `gapCircle_good`: every s on the circle is a good point (¬badPoint s) — from the hgapInt + hsz + norms. 2. The mapsTo: DifferentiableOn Gentire (ball 0 R) (from gentire_analyticAt_and_eq.1: AnalyticAt ∀ s ⟹ AnalyticOnNhd ⟹ DifferentiableOn on the open ball) + the sphere bound ⟹ MapsTo (ball 0 R) (closedBall (Gentire 0) R₂) via Zeta23's AnalyticOn.norm_le_of_norm_le_on_sphere (check its exact name/signature in Zeta23). 3. The Schwarz application per z₀ (‖z₀‖ < R): dist (Gentire z₀) (Gentire 0) ≤ (R₂/R)·‖z₀‖·... check Complex.dist_le_div_mul_dist_of_mapsTo_ball's exact form. 4. The growth bound: Ĉ₀(R+2) ≤ 5·log R + (log R)³/R-ish bounds with Real.log_le_rpow (check exists). 5. The ratio → 0 ⟹ dist = 0 ⟹ Gentire z₀ = Gentire 0 for all good z₀ (need ‖z₀‖ < R for SOME gap circle R > |z₀|: exists_gapCircle_radius (hZC) at k large: R ∈ [4k+2.5, 4k+3] > ‖z₀‖ for k > ‖z₀‖/4·...). 6. The capstone partialFraction_identity (hZC : ZeroCountProp). Let me write the STATE update now. Keep it focused.

Session 033 complete. Summarize for the user.
**Session 033 COMPLETE — ii′-5e-v-c: the Fexpr circle bound is proved.** **`Fexpr_circle_le`** (LiCircleBound.lean:3875): on the γ-gap circle ‖s‖ = R (k ≥ 4000), $$\|\mathrm{Fexpr}\, s\| \;\le\; 2\cdot\mathrm{lowZeroConst} + \mathrm{dirichletC2} + 400000\cdot A_0\cdot \hat C_0(R{+}2)\cdot(\log R)^2$$ Sub-stage commits: - **c-i** `1c76576` — `logDeriv_Gammaℝ_eq_of_not_neg_nat`: the (G) formula logDeriv ΓR s₀ = −(log π)/2 + ½ψ(s₀/2) at **any** non-pole point, via direct `logDeriv_mul` on `Gammaℝ_def` (digamma := logDeriv Γ by definition) — the im ≠ 0 hypothesis of 5e-ii's (G) was only pole-avoidance. This discharges the real point s = −R with **no continuity argument** (a design-level simplification vs journal-030's plan). Plus `gapCircle_sep` (the arc-analysis separation standalone), `nearZeros_count_le`, `gapCircle_sep_of_mem_nearZeros`. - **c-ii** `5da957c` — `digamma_right_le` (re ≥ 1.75: 48+23·log) and `digamma_circle_le` (uniform ‖ψ(s/2)‖ ≤ 62+23·log(2+R/2): strip sub-log / right_le / left near-axis via 5e-ii (A) c = 1/8 from the ℤ-clearance — the R+re s = im²/(R−re s) identity avoids all square roots). - **c-iii** `2fc359f` — `logDeriv_circle_le` (three regions: (i) re ≥ 2 Dirichlet; (ii) re ∈ [−5/2, 2] — |im| ≥ 10 automatic — 5c/5d capstones + near sum ≤ 32Ĉ₀·count; (iii) re < −5/2: `logDeriv_zeta_fe` with all 10 hypotheses discharged + Dirichlet at 1−s + the ΓR bracket) and the six-norm assembly. - **Closure** `df4e083` — journal-033, STATE, NGUYEN.md, db. Audit (`audit-session033-axioms.txt`): 14 decls, **3 standard axioms only**. File ~3928 lines, clean, zero warnings, not yet root-imported (by design — the file's capstone lands at 5e-v-d). **Next (session 034): 5e-v-d** — the Schwarz squeeze: Gentire entire + the circle bound ⟹ MapsTo into closedBall (Gentire 0) (R₂+1) ⟹ `Complex.dist_le_div_mul_dist_of_mapsTo_ball` ⟹ dist (Gentire z₀) (Gentire 0) ≤ (R₂+1)/R·‖z₀‖ → 0 (via Ĉ₀(R+2) ≤ 5 log R and log R ≤ 4·R^{1/4}) ⟹ **Gentire ≡ B** ⟹ the capstone `partialFraction_identity` under `ZeroCountProp`. Then ii′-5f (tight constants) → ii′-3b → ii′-3c → ii′-6 → ii′-7.

Everything is persisted: - Working tree clean except the pre-existing untracked paper build artifacts (same as at session start — gitignore-covered build files, not research state). - All session work committed (df4e083 closure commit on top). - STATE.md has the explicit NEXT ACTION for session 034. - Journal, NGUYEN.md, db all updated and committed. Safe to shut down. Brief sign-off.
All state is safely persisted — working tree has only the pre-existing paper build artifacts (gitignore-covered). Session 033 is fully closed: - **Code**: 4 commits (`1c76576`, `5da957c`, `2fc359f`, closure `df4e083`) - **Journal**: `research/journal/session-033.md` - **STATE.md**: NEXT ACTION staged for session 034 (5e-v-d, full design inline) - **NGUYEN.md**: checklist + session log updated - **db**: session 33 registered Enjoy the break — when you're back, we pick up at the Schwarz squeeze ⟹ the ∃ B capstone `partialFraction_identity`, which completes tier ii′-5e and unlocks 5f (tight constants) on the road to closing `SfBoundProp`.
