Summary

Focus: Phase 0 + Phase 1 groundwork (research session 002).

What happened:

Deep-read the Anthropic RH paper and reproduced the proof chain (D-002…D-006, incl. the rank–trace lemma and ceiling/sharpness analysis).
Verified the window values R(ψ₀) and R(ψ_MT) symbolically and numerically (E-001); audited zeta-23-lean (D-007); built the numerical sandbox with 10⁴ zeros (E-002/E-003).
Phase 1: re-derived the bandwidth-one ceiling (D-009) and mapped the obstruction — Track A moved toward monitoring mode.
Began Track C and read Lagarias's Theorem 2 (the arithmetic formula) in detail.

Outcome: Phases 0–1 essentially complete; the Suzuki/Track-C line opened.

Conventions clear. Now write E-009a: implement Suzuki's g(t). Formula (eq. 1.3): g(t) = −4(e^{t/2}+e^{−t/2}−2) + Σ_{n≤e^{|t|}} (Λ(n)/√n)(|t|−log n) − (|t|/2)(ψ(1/4) − log π) − ¼[Φ(1,2,¼) − e^{−|t|/2}Φ(e^{−2|t|},2,¼)] Validation vs eq. 2.2 near origin: g(t) = ½|t|log|t| + A|t| + (prime sum) + r(t), r even C² O(t²), A = ½(log(2π) − ψ(2)) = ½(log(2π) + γ_E − 1) ≈ 0.707546. Check: ψ(2) = 1 − γ_E, so ½(log(2π) − (1−γ_E)) = ½(log(2π) + γ_E − 1). Compute: log(2π)=1.8378770664, γ_E=0.5772156649; sum−1 = 1.4150927313; half = 0.7075463657. ✔ Also compute the constant: −(1/2)(ψ(1/4) − log π). ψ(1/4) = −γ − π/2 cot(π/4) − 3 log 2 = −γ − π/2 − 3 log 2 ≈ −0.5772156649 − 1.5707963268 − 2.0794415417 = −4.2274535334. log π = 1.1447298858. ψ(1/4)−logπ = −5.3721834192. So −(|t|/2)(−5.372...) = +2.68609...|t|. Φ(1,2,1/4) = Σ_{k≥0} 1/(k+1/4)² = 16·ψ₁(1/4)... Actually Σ 1/(k+1/4)² = polygamma(1, 1/4) = ψ'(1/4). So Φ(1,2,1/4) = ψ'(1/4) ≈ 17.197329... (ψ'(1/4) = π²/sin²(π/4)·... anyway mpmath computes it). Validation approach in E-009a: 1. Implement g(t) directly. 2. Near-origin test: for small t (say t = 1e-3..1e-1, below ½log2≈0.3466 so prime sum = 0), compute g(t) − ½|t|log|t| − A|t| and check it's O(t²), i.e., ratio /t² converges to a constant as t→0. Also r must be even. 3. Evenness check: g(−t) = g(t). 4. Tabulate g on a mesh for later Galerkin use? D-018 says "tabulate g on a mesh (cached CSV)". The Galerkin needs g(x−y) for x,y ∈ [−a,a], i.e., g on [−2a, 2a]. Mesh with fine resolution near 0. Maybe produce a table at a values TBD in E-009b. For E-009a, tabulate g(t) on a mesh of [0, 2a_max] with a_max maybe 10? Let's decide: E-009b uses a few a values; g needs values up to 2a. Let's tabulate on a nonuniform mesh? Simplest: compute g at requested points on demand in E-009b with caching. But D-018 explicitly says tabulate. I'll tabulate on a uniform fine mesh on [0, 2A] for A=... let's pick a_max = 4 (so t up to 8, prime sum up to e^8 ≈ 2981 terms — fine). Actually Galerkin matrix entries are double integrals over element pairs; we can integrate numerically using g evaluations. A cached table + interpolation could speed. But singularity |t|log|t| at 0 — interpolation near 0 needs care. Alternative: E-009b computes double integrals via quadrature calling g directly; cost = (pairs of elements) × quadrature points. With 300 elements, ~45k diagonal-ish pairs... double integrals expensive but doable with caching: entries depend only on |i−j| offsets (Toeplitz-like structure on uniform mesh!). Q(u,v)=⟨G_a u′,v′⟩ with hat functions: u′ piecewise constant on elements; the form matrix becomes a Toeplitz matrix of second differences of G's second integral. Actually with uniform mesh and hat functions, the matrix is Toeplitz: entries depend on i−j only. Great — we only need ∫∫ g over offset pairs for O(N) distinct offsets, not O(N²). Even better: define F(s) = ∫₀^s ∫₀^? ... The entry for offset k is a double integral of g(x−y) over two unit elements at distance k, which is a second-difference stencil of the second antiderivative of g. We can compute G2(t) = second integral of g numerically on the mesh, then entries are finite differences. That requires computing G2 via cumulative quadrature — g has |t|log|t| singularity, integrable; use analytic handling of the singular part plus numerical integration of the regular part. Better plan for E-009b: decompose g(t) = ½|t|log|t| + A|t| + P(t) + r(t) where the first two are analytic (second integrals known exactly), P(t) is the prime sum (piecewise linear in |t|! since Σ(Λ(n)/√n)(|t|−log n) for n ≤ e^{|t|} — it's piecewise linear in |t| with kinks at log n; second antiderivative piecewise cubic, computable exactly), and r(t) = remaining smooth even part = the digamma/lerch terms plus the −4(cosh−2) adjustments... wait need care: the direct formula includes −4(e^{t/2}+e^{−t/2}−2) which is smooth, plus the |t| digamma term, plus the Lerch term. The decomposition eq 2.2 says the sum of those smooth terms minus their linear part gives r. Simplest: define r(t) = g(t) − [½|t|log|t| + A|t| + P(t)] numerically, then integrate r numerically (smooth, C²). This is clean and avoids differentiating anything. So E-009a deliverables: - g(t) mpmath implementation. - Self-tests: evenness, eq 2.2 asymptotic (ratio → constant), known constant values (e.g., Φ(1,2,1/4) = ψ'(1/4) check). - Tabulate g(t) on a mesh [0, T_max] with T_max maybe 12, step fine near 0 (e.g., geometric+uniform hybrid or just uniform small step 1e-3 → 12000 points; each g eval involves a prime sum up to e^{12}≈162755 terms — that's heavy: 12000 × up to 160k terms. Too heavy at high precision? We can compute with floats for the sum since Λ(n)/√n terms; do it in numpy with log tables, vectorized per t. 12000 t-values × 160k = 2e9 ops — heavy but GPU/numpy can handle ~minutes. Alternatively restrict mesh to what's needed in E-009b: a values maybe 2–6, so t up to 12. Hmm. Wait — actually what a range makes sense? Bottom eigenvalues of A_a should relate to zeros γ: the interval length 2a, and the spectral scaling... Kim et al. report Archimedean spectral law. For first comparisons, small a (like a = 1..5) with the first zeros γ₁=14.13. The natural scaling: the operator approximates eigenvalues via z = γ·a? In Suzuki's convergence, W(a,θ;z) zeros → zeros of ξ(½−iz), i.e., z = γ at real values as a→∞. But finite-a bottom eigenvalues will be larger than γ₁ (finite-interval compression). So we need a as large as feasible to see approach. Let's plan a ∈ {1, 2, 3, 4, 5} first pass. t ∈ [−2a, 2a] → t up to 10. Prime sum up to e^{10} ≈ 22026 terms per evaluation. Manageable. For E-009a tabulation: uniform mesh h = 1e-3 on [0, 10]? That's 10k points; each point sums over primes ≤ e^t. Vectorized in numpy: for each t, sum over n ≤ e^t. Precompute log n and Λ(n)/√n arrays up to e^10 = 22027 integers. For 10k t values, total work ~ 10k × average ~10k terms = 1e8 — numpy fine (chunked). Actually simpler: the prime-sum part P(t) is piecewise linear in t with breakpoints at log n! P(t) = Σ_{n≤e^t}(Λ(n)/√n)(t − log n) = M₁(t)·t − M₀(t) where M₁(t)=Σ_{n≤e^t} Λ(n)/√n, M₀ = Σ (Λ(n)/√n) log n — step functions. We can evaluate exactly at any t with a searchsorted + cumsum. Super fast, no mesh needed. So g can be evaluated efficiently at arbitrary t without a precomputed table. So E-009a: implement g with exact prime-sum via cumsum arrays, validate, then tabulate a modest CSV (mesh for Galerkin use or for plotting). I'll tabulate on [0, 10] at step 1e-3 in float64 (CSV) — cheap given fast evaluation. Also validation: r(t) = O(t²) even C². Compute r(t) for t in {1e-1, 3e-2, 1e-2, 3e-3, 1e-3}, r(t)/t² should converge to a constant; also r(−t)=r(t). We can also derive the exact limiting constant: r(t)/t² limit = ½ r″(0). We can just report empirical convergence. Additionally, a second self-check: compute g(t) two ways — direct definition vs the eq 2.2 decomposition with r computed... that's circular. Better independent check: the von Mangoldt explicit formula connection. Hmm. Another sanity check: g(0) = 0. Direct: at t=0: −4(1+1−2)=0; prime sum 0; digamma term 0; −¼[Φ(1,2,¼) − 1·Φ(1,2,¼)] = 0. So g(0)=0 trivially. Better nontrivial check: derivative? g'(0+) = A (from 2.2, since ½|t|log|t| derivative → 0, prime sum 0 near 0, r=O(t²)). Compute numerically g(t)/t → A as t→0+. g(t)/t = ½ log t + A + o(1) → diverges... no: ½|t|log|t|/t → ½ log t → −∞. Hmm so g(t)/t ~ ½ log t + A. Check g(t)/t − ½ log t → A. That's a good test. Use mpmath at dps 30 for validation at small t, and float64 for the table. Constant Φ(1,2,1/4): mpmath lerchphi(1,2,0.25). Note mpmath lerchphi(z,s,a) = Σ z^k/(a+k)^s. So Φ(e^{−2t},2,1/4) = lerchphi(exp(-2t), 2, 0.25). ✔ ψ(1/4) = mpmath.digamma(0.25). Λ(n): von Mangoldt — Λ(n) = log p if n = p^k else 0. Compute via sympy or simple sieve. For n up to e^10 ≈ 22027, easy sieve. Let me also record: A = 0.7075463656... and digamma coefficient −½(ψ(1/4)−log π) = +2.6860917096...? compute: 5.3721834192/2 = 2.6860917096. The script: research/numerics/scripts/E-009-suzuki-screw-function.py, outputs E-009-suzuki-screw-function.csv (+ .json). Register in db via db.py log-experiment afterward. Design: - Part A (validation, mpmath dps 30): evenness at several t; eq 2.2 limit r(t)/t² convergence for t→0 (t ≤ 0.3, below ½log2); g(t)/t − ½log t → A; lerchphi identity check Φ(1,2,1/4) = polygamma(1,1/4). - Part B (tabulation, float64): mesh t_k = k·h, h=1e-3, [0,10], columns t, g, plus decomposition columns maybe (singular, prime, smooth). CSV with metadata json. - Part C maybe: small-a Galerkin preview? No, that's E-009b. Write the script now. For high-precision prime sums, do them with mpmath too but n ≤ e^{0.3} tiny. For table part use float64 cumsum. Edge: at t where e^t crosses integers, sum over n ≤ e^t inclusive. Use n_max = floor(exp(t)+1e-12). With cumsum arrays indexed by n, searchsorted(logn_array, t) with side='right' on logs of integers. Precompute for n=2..N: lam[n] (Λ(n)/√n) and lamlog[n]. Cumsums C1[n], C0[n]. P(t) = C1[m]·t − C0[m], m = #{n≥2 : log n ≤ t} = floor(e^t) (careful float). Use m = int(floor(exp(t) * (1+1e-15)))... for t up to 10 fine in double. Or searchsorted on log array with t + tiny epsilon. Let me write the script. Sieve for Λ: standard: lam_log[n] = log p if n is a prime power. Sieve: for each prime p ≤ N, for multiples p^k set Λ = log p (only the highest power gets it since we overwrite sequentially per p: for each p, for m in powers: lam[m]=log p; since different p's powers don't collide except n=1, fine). CSV: keep moderate. h=1e-3 → 10001 rows. Fine. Validation tolerances: - evenness: |g(t)−g(−t)| tiny (mpmath, exact same computation basically — but still run). - A-limit: t=1e-4: g(t)/t − ½ log t ≈ A + O(t) → tolerance 1e-3. - r ratio convergence: r(t)/t² for t = 0.2, 0.1, 0.05, 0.02, 0.01: should stabilize (differences decreasing, ~linear in t since r = c₂t² + O(t³)? r is even C², but is it C³? even C² means r(t)=c₂t²+o(t²), and evenness forces r(t)=c₂t²+O(t⁴)? Not necessarily — even C² function: r(t) = r(0)+r'(0)t+½r''(0)t²+o(t²); evenness kills r'(0) only if differentiable. r even C² ⇒ r'(0)=0, r(t)=½r''(0)t²+o(t²). Ratio converges to ½r''(0). Check successive values differ by decreasing amounts; report last two difference < threshold like 0.05 relative. Also we can compute r''(0) analytically for comparison? r(t) = smooth part of g minus A|t|... The smooth terms: −4(e^{t/2}+e^{−t/2}−2) = −8(cosh(t/2)−1) = −t²/2·... cosh(t/2)−1 = t²/8 + t⁴/384..., so −8·t²/8 = −t². So this term contributes −t², i.e., ½r''(0) gets −1 from here. The Lerch term: L(t) = −¼[Φ(1,2,¼) − e^{−t/2}Φ(e^{−2t},2,¼)] for t>0. At t=0, L=0. Expand: e^{−t/2}Φ(e^{−2t},2,¼) = Σ_k e^{−2tk}/(k+¼)² · e^{−t/2} = Σ_k e^{−t(2k+½)}/(k+¼)². Let u_k = 2k+½ = 2(k+¼). So term = Σ_k e^{−t·2(k+¼)}/(k+¼)². At t: Σ [1 − 2(k+¼)t + 2(k+¼)²t² − ...]/(k+¼)² = Φ(1,2,¼) − 2t Φ(1,1,¼) + 2t² Φ(1,0,¼) − ... where Φ(1,0,¼) = Σ 1 diverges! Hmm, Φ(1,0,¼) = Σ 1 diverges, so the t² coefficient diverges — meaning the expansion has non-analytic terms (t² log t?) — consistent with the ½|t|log|t| singular structure. So don't expand analytically; skip. The digamma linear term: −(t/2)(ψ(1/4)−logπ) for t>0. The full linear coefficient in t: from digamma term: −½(ψ(1/4)−logπ) = 2.686...; from Lerch term: +¼·2Φ(1,1,¼) = ½Φ(1,1,¼) = ½·ψ(1/4)... Φ(1,1,¼) = Σ 1/(k+¼) diverges! Also divergent. Right — the ½|t|log|t| singularity comes from combining these. So no simple analytic r''(0). Fine — empirical convergence only, plus the A-limit test which is clean. Hmm wait, actually the A-limit test: g(t)/t − ½ log t → A as t→0+. From 2.2: g(t) = ½t log t + A t + r(t), r=O(t²) ⇒ g(t)/t − ½ log t = A + O(t). ✔ Clean test. Another validation: compare g computed from direct formula against an independent numerical evaluation? We could validate the whole formula against the Weil explicit formula numerically — that's what E-009b does implicitly via spectrum. Alternatively validate via Suzuki eq 1.3's origin... skip; the internal checks + literature constants suffice for E-009a. Also check Φ(1,2,1/4) = polygamma(1, 1/4) in mpmath — verifies our lerchphi argument convention. And A constant check. Alright, write the script. For the JSON sidecar: follow E-008's pattern (metadata, parameters, checks, results summary, runtime). I'll mirror its structure; let me look at the rest of E-008 to copy JSON conventions.

Conventions noted. Let me see the JSON sidecar pattern in E-008's tail before writing E-009a.

Now write E-009a script. Plan: ```python """E-009a — ...""" ``` Key functions: - von Mangoldt sieve up to N = ceil(e^10) ≈ 22027 → use 22100. - prime_sum(t) via cumsum arrays (float64) and mpmath exact version for small t (direct loop). - g_direct(t): mpmath high precision: -4*(exp(t/2)+exp(-t/2)-2) + primesum(|t|) - (|t|/2)*(digamma(0.25)-log(pi)) - 0.25*(lerchphi(1,2,0.25) - exp(-|t|/2)*lerchphi(exp(-2*|t|),2,0.25)) Note prime sum Σ_{n≤e^{|t|}} Λ(n)/√n (|t|−log n). mpmath lerchphi signature: lerchphi(z, s, a). ✔ Validations (dps 30): 1. lerch convention: lerchphi(1,2,1/4) == polygamma(1, 1/4). 2. Evenness: g(t)−g(−t) = 0 for t in {0.7, 2.3, 5.1}. 3. A-limit: g(t)/t − ½log t → A for t = 1e-2, 1e-3, 1e-4 (t below ½log2 so prime sum = 0). Error should be O(t): check |err(1e-4)| < 1e-3 and decreasing ~10x each step. 4. r-ratio: r(t)/t² convergence for t = 0.25, 0.125, ..., ~2e-3: differences decrease; report. Tabulation float64: t in [0,10], h=1e-3, columns: t, g(t), prime_part(t), smooth check maybe. Columns: t,g,prime_sum. Compute g via float64 path: use math/cumsum; lerchphi float64 via mpmath at dps 15 — 10k lerchphi evals might be slowish but OK (~ each lerchphi with small z converges fast; maybe 1ms each → 10s). Fine. Actually we can vectorize the Lerch sum directly: Φ(e^{−2t},2,1/4) = Σ_{k=0}^{K} e^{−2tk}/(k+.25)², converges like e^{−2tK}; for tiny t need many terms (for t=1e-3, need K ~ 1e4 for tail e^{−2tK}<1e-12 → K ~ 14000). Hmm, for small t the direct sum is slow-converging. Use mpmath lerchphi which handles it. 10001 evals — test speed; maybe a few minutes. Acceptable. Alternatively precompute on a coarse mesh + interpolate... no, keep exact. Actually, better: compute the float64 table in numpy vectorized lerch for t ≥ some cutoff, and mpmath for t < cutoff. Meh — just use mpmath for all; if too slow, adjust. Let me estimate: lerchphi(z,s,a) for z close to 1 uses... mpmath may be slow (it does series acceleration, maybe 0.1-1ms). 10k × 1ms = 10s. OK. For float64 speed, also possible: note the combination −¼[Φ(1,2,¼) − e^{−t/2}Φ(e^{−2t},2,¼)] is small for small t (cancellation!). At t=1e-3, Φ(e^{−2t},2,¼) ≈ Φ(1,2,¼) − 2tΦ(1,1,¼)... Φ(1,1,¼) diverges, so difference ~ t log t·(−?) Anyway cancellation of leading digits: Φ values ~17, difference ~ 1e-3·log ~ 1e-3 → lose ~4 digits at t=1e-3, worse at smaller t. float64 gives ~12 reliable digits at t=1e-3, at t=1e-4 ~11... For Galerkin purposes that's plenty. But for CSV table, note the caveat. Alternatively store the combination computed at dps 30 then converted to float — better. Use mpmath dps 30 for the whole table computation? 10k evals with prime cumsum fast — the lerchphi at dps 30 maybe 10ms each → 100s. Acceptable but let's do dps 30 for t < 0.1 (100 points) and dps 20 elsewhere. Actually simpler: do everything at dps 25; prime sum via float cumsum (error negligible relative). Let's estimate lerchphi cost... I'll just write it with a progress print and run; if slow, optimize. Hmm — actually a smarter approach for the table: the singular structure is at t=0 only. We can precompute the Lerch-combination on the mesh efficiently by noting Φ(e^{−2t},2,1/4) at mesh points t_k = k h: it's Σ_k z_k^m/(m+1/4)² with z = e^{−2h}. That's a power series evaluated at geometric points — could use fast multipoint, overkill. Just mpmath. Let me now write the script. Also A constant: A = 0.5*(log(2*pi) + euler - 1) = 0.70754636568...? compute: 1.83787706641 + 0.57721566490 = 2.41509273131; −1 = 1.41509273131; /2 = 0.70754636565. D-018 says ≈ 0.707546 ✔. digamma(0.25): −γ − π/2·cot(π/4) − 3log2 = −0.5772156649 − 1.5707963268 − 2.07944154168 = −4.22745353338. −log π shift: ψ(1/4) − logπ = −4.22745353338 − 1.14472988585 = −5.37218341923. Coefficient −(|t|/2)(...) = +2.68609170962·|t|. Write CSV with columns: t, g_t, prime_sum_t. Plus maybe g minus singular parts? Keep simple: t,g,prime_sum. Checks: - check_lerch_identity - check_evenness (max diff < 1e-25) - check_A_limit (err at 1e-4 < 2e-4 and monotone decreasing ~ ×10) - check_r_ratio_convergence (|last two ratios| relative diff < 0.02) - check_table_finite & monotone-ish? Table sanity: g(10) finite, no NaN. JSON sidecar with key values: A constant, r2 = lim r(t)/t² estimate, sample g values, digamma coefficient. Threshold for A-limit test: err(t) ≈ C·t with C = −½r''(0)·... err = (A + (r(t)/t)) − A... g(t)/t − ½ log t = A + r(t)/t = A + O(t). At t=1e-2: O(1e-2·c). We don't know c = ½r''(0) magnitude; from the −t² contribution alone c≈−1 → err ~ 1e-2 at t=1e-2? Wait r(t)/t = O(t), so at 1e-2 err ~ c·1e-2 with c~1 → 1e-2. Hmm, that's a big tolerance. Check ratio err(1e-3)/err(1e-2) ≈ 0.1. Test: |err(1e-4)| < 3e-3 and err ratios in [0.05, 0.2]. Empirically the r-ratio test will pin c: lim r(t)/t² = c, then expected err(1e-4) = c·1e-4. I'll compute c first, then test A-limit err ≈ c·t within 20%. Order: compute r-ratio first to get c, then A-limit test against A + c·t. Actually r(t)/t² → c, and g(t)/t − ½log t − A = r(t)/t = c·t + o(t). So test |observed − c·t| / |c·t| small. Good. But note: the A-limit test uses t below ½ log 2 ≈ 0.3466; 1e-2..1e-4 fine. r-ratio uses t up to 0.25 (also below 0.3466 ✔). Now the table: use mpmath mp.dps = 25 for lerchphi, but prime sum from float cumsum (error ~1e-13·magnitude, fine at 25dps? It contaminates the 25-digit value — but we only print ~17 digits to CSV. Set dps 20 for speed.) Runtime estimate for 10001 lerchphi calls at dps 20: unknown; add time printout. If too slow I'll subsample near 0. Let me include a fallback: compute lerch combination via direct series when e^{−2t} < 0.5 (t > 0.35): fast numpy vectorized. For t ≤ 0.35 (350 points) use mpmath. Actually z = e^{−2t} < 0.5 means terms decay by ≥0.5^k — need only ~50 terms for 1e-15. For t>0.35 vectorized numpy over 10k points × 60 terms trivial. For t ≤ 0.35: 351 mpmath calls — fast. Also at t=0: g=0 exactly, set directly. Numpy direct series: Phi(z) = Σ_{k=0}^{K} z^k/(k+0.25)^2. For array of z values (all < 0.5), K=80. Then combination C(t) = −0.25*(Phi1 − exp(−t/2)*Phi(exp(−2t))) where Phi1 = polygamma(1,0.25) float64 = 17.19732915450756... get via mpmath once at dps 30, hardcode as computed value in JSON. Also −4(cosh term): −4*(exp(t/2)+exp(−t/2)−2). digamma term float: coeff = 2.6860917096128... compute via mpmath once. Prime sum via cumsum: logs = log(n) for n=2..N; sieve Λ; lam = Λ/√n; C1 = cumsum(lam), C0 = cumsum(lam*log n); m = np.searchsorted(logs, t, 'right'); P = C1[m−1]*t − C0[m−1] (if m>0). For high-precision validation prime sum: direct mpmath loop over prime powers ≤ e^t (t ≤ 0.25 → n ≤ 1, wait e^0.25 = 1.28 < 2, prime sum = 0!). Oh nice — for ALL validation t ≤ 0.3466 the prime sum vanishes. So validation needs no prime sum at all. But evenness test at t=2.3, 5.1 does need it — use mpmath loop there (n ≤ e^5.1 = 164, small). Sieve: N = int(exp(10))+2 = 22028. lam array. Now write the script. def von_mangoldt_sieve(N): returns array lam_log[0..N] where lam_log[n] = log p if n = p^k. ```python lam_log = np.zeros(N+1) is_composite = np.zeros(N+1, bool) for p in range(2, N+1): if not is_composite[p]: pk = p while pk <= N: lam_log[pk] = np.log(p) # mark multiples of p composite? standard sieve: mark p-multiples pk *= p for m in range(2*p, N+1, p): is_composite[m] = True ``` Wait marking must happen for all p; do standard sieve first for primes, then powers. CSV rows 10001 — fine. JSON checks and key values. Let me also add g evaluation at interesting points for the record: g(½log2) (first prime kink), g(log 2), g(log 4)... record in JSON. Write the file now.

Conventions clear. Writing the E-009a script now.

Even the full call returns empty! So eigvalsh is failing silently?? No — it returned empty array without raising. That's bizarre. Maybe the issue: Mz with the ones-vector constraint: M = toeplitz(2/3, 1/6...) is SPD, Z full column rank ⇒ Mz SPD. Hmm. Wait — maybe scipy 1.18 changed the signature: eigvalsh(a, b=None, ...) — did I pass positionally correctly? sla.eigvalsh(Qz, Mz, subset_by_index=[0,11]) — should be fine. Empty return without error is weird. Let me check driver defaults: scipy.linalg.eigvalsh default driver for generalized... "gvd". Hmm. Let me debug: try driver='gv' or check for NaNs. Random Q could produce... no, empty is wrong regardless. Test simpler.

Even the full call returns empty. Debugging deeper.

Mz is symmetric (check didn't print, but Mz eigvalsh returned empty too). So eigvalsh on Mz returns empty — even plain! Mz = Zᵀ M Z where Z from QR. Is Mz actually symmetric finite? Let me check: np.linalg.qr(np.ones((n,1)))[0] — for n=50, QR of 50×1 gives Q 50×50. Z = Q[:,1:] (50×49). Mz 49×49. eigvalsh returns empty → probably NaN/Inf in Mz? toeplitz with np.r_[2/3, 1/6, np.zeros(n-2)] — that's fine. Wait — maybe reduced QR default mode: np.linalg.qr default mode='reduced' — for (50,1) input, reduced gives Q of shape (50, 1)!! Not (50,50). So Z = Q[:,1:] is EMPTY (50×0). That's the bug. Need mode='complete'.

Found it — `np.linalg.qr` defaults to reduced mode, so for an (n,1) input it returns Q of shape (n,1) and Z is empty. Need `mode='complete'`. Also fixing the entry check to isolate the table part.

ALL eigenvalues are tiny negative numbers (~−1e-5..−1e-3), clustered near 0. This means the whole spectrum is collapsing to ~0⁻. The stiffness matrix Q must be nearly zero/negative tiny, while the mass matrix dominates. So Q entries are tiny. Suspect: a scale/sign error in Q construction — or the whole Q is ~ h²-scale smaller than intended... The eigenvalues λ = Q/M: if Q entries have an overall error making them ~1e-4, eigenvalues ~1e-4. Wait, maybe sign: Q should be PSD (Weil positivity), all eigenvalues slightly negative suggests Q ≈ −(tiny)·M. Possibly the stiffness entries are dominated by discretization error of a near-zero matrix? Is Q supposed to be ~0? Hmm: Q(u) = ∫∫ g(x−y) u′(x) u′(y). For u a hat: u′ = ±1/h... the double integral ∫∫ g(x−y) over the support: with g of order 1 and supports of size h, Q entries ~ h²·g/h² = g·O(1). Hmm — that's what I estimated, entries O(g) ~ O(1), and eigenvalues should be O(g/h-ish scale)... but M eigenvalues ~ h. So generalized eigenvalues ~ O(1)/O(h) ~ O(1/h) ~ 200. We get 1e-4. So Q entries must be ~1e-6 — i.e., S differences nearly cancel to zero. Something's off in S. Debug: print S(k), Q entries directly. Let me compute S_sing(0) and S_table(0) for h=0.005: S_sing(0) = 2F(h), F(0.005) = A·h³/6 + h³log(h)/12 − 5h³/72. h³ = 1.25e-7. A h³/6 = 1.47e-8. h³ log h /12 = 1.25e-7·(−5.3)/12 = −5.5e-8. So F ≈ −4e-8, S_sing(0) ≈ −8e-8?? But direct: S(0) = 2∫₀^h (h−s)σ(s)ds with σ(s) = ½s log s + A s: ∫₀^h (h−s)·½ s log s ds: at s=h/2, value ≈ (h/2)(h/4)log(h/2)·... magnitude ~ h³·log ~ 1e-7·(−5)/8 ~ −1e-7·... yes ~1e-7. And A part: ∫(h−s)A s ds = A h³/6 ~ 1.5e-8. So S ~ −1e-7·2 ~ −2e-7 scale... wait let me be careful: 2∫₀^h(h−s)½ s log s ds = ∫₀^h (h−s) s log s ds = h∫s log s − ∫s² log s = h(h²/2 log h − h²/4) − (h³/3 log h − h³/9) = h³[(1/2−1/3)log h − 1/4 + 1/9] = h³[log h/6 − 5/36]. h=0.005: log h = −5.298; = 1.25e-7·(−0.883 − 0.139) = −1.28e-7. A part: 2·A h³/6 = A h³/3 = 2.9e-8. Total S(0) ≈ −9.9e-8. Then Q_0 = (2S_0 − 2S_1)/h². S_1 = F(2h) − 2F(h) + F(0) = F(2h) − 2F(h) = 8F(h)·(log adjustments) − 2F(h): F(2h) = A(2h)³/6 + (2h)³log(2h)/12 − 5(2h)³/72 = 8[A h³/6 + h³(log h + log 2)/12 − 5h³/72] = 8F(h) + 8h³·log 2/12 = 8F(h) + (2/3)h³ log 2. So S_1 = 6F(h) + (2/3)h³ log 2 ≈ 6·(−4.4e-8)... F(h) = h³(A/6 + log h/12 − 5/72) = 1.25e-7·(0.1179 − 0.4415 − 0.0694) = 1.25e-7·(−0.393) = −4.9e-8. S_0 = 2F(h) = −9.8e-8 (sing part) + table part. S_1 = 6·(−4.9e-8) + (2/3)(1.25e-7)(0.693) = −2.95e-7 + 5.8e-8 = −2.4e-7 (sing part). Then 2S_0 − 2S_1 = 2(−9.8e-8 + ρ_0) − 2(−2.4e-7 + ρ_1) ≈ 2.8e-7 + 2(ρ_0 − ρ_1). Q_0 = 2.8e-7/2.5e-5 ≈ 0.011 + table part. Hmm so Q entries ~ 0.01–1 scale. Eigenvalues should be ~ Q/M ~ 0.01/0.003 ~ 3... but we got −1e-4?! So Q as built has nearly-zero eigenvalues — meaning Q is nearly singular with tiny negative eigenvalues... OR the mass matrix is huge relative... M diag 2h/3 = 0.0033, M eigenvalues between h/3 and h. Q eigenvalues: if Q entries O(0.01) Toeplitz, eigenvalues O(N·0.01)? Toeplitz eigenvalues ~ symbol range. Generalized eigenvalues ~ ratio of symbols. We got all λ ~ −1e-5..−1e-3, i.e., Q's symbol ≈ 0 mostly, slightly negative. Possibility: a coding bug making S(k) ≈ constant in k (then 4th differences ~ 0). E.g., S_table returning same value for all k, or S_sing mis-evaluated. Let me just print S(k), q[k] for small script debug. Actually wait — I bet the issue is different: the whole spectrum near zero negative AND λ₁ MORE negative with finer h... and magnitude ~1e-4 at a=3. Suspicious pattern: maybe Q is correct scale but has a large negative eigenvalue? No — all 12 eigenvalues tiny. Let me debug interactively: compute q[0..5], S values, and eigenvalues of Q itself.

All eigenvalues collapse to ≈0⁻ — Q is nearly singular or mis-scaled. Debugging the S/q values directly.

The symbol takes both signs — so Q is genuinely indefinite. Symbol values O(±0.01–0.07). But the generalized eigenvalues were all ≈ −1e-4?? With symbol range ±0.06 and mass symbol h(2/3 + cos θ/3) ~ 0.005·(0.33..1), the generalized eigenvalues should range roughly λ(θ) = sym(θ)/m(θ) ~ ±0.06/0.005 = ±12. But we got all −1e-4! Contradiction — so the constraint projection Z must be doing something drastic, OR my eigenvalue solve had another bug. Wait — the symbol-to-eigenvalue correspondence holds for the UNCONSTRAINED Toeplitz. The constraint Σc_i = 0 removes only ONE direction — can't change ±12 to −1e-4. So the eigenvalue computation itself was broken! Let me check: eigvalsh(Qz, Mz, subset_by_index=[0,11]) — maybe with mode='complete' fix now Z is fine. Earlier failure was empty Z — that was FIXED. The run that produced −1e-4 used... I fixed mode='complete' BEFORE the successful run. Hmm, but then eigenvalues should reflect ±12 range. Wait, maybe not: subset_by_index=[0, N_EIG−1] with N_EIG=12 — returns 12 smallest. The 12 smallest should be ≈ min of symbol/mass ~ −12, not −1e-4. Unless... the mass matrix M construction is wrong! M = toeplitz(np.r_[2h/3, h/6, zeros(n−2)]) — toeplitz(c) with c as first column: M[0] = [2h/3, h/6, 0...] — symmetric tridiagonal ✔. M eigenvalues ∈ [h/3, h] ✔ SPD. Qz = ZᵀQZ: restriction. Its bottom eigenvalue ≥ ... restriction bounds: eigenvalues of ZᵀQZ interlace within [λ_min(Q), λ_max(Q)]. λ_min(Q) ≈ symbol min −0.028. So generalized ≥ −0.028/0.005 ≈ −5.6. But we got −1e-4?!?! IMPOSSIBLE unless Q as passed to spectrum() differs — OH WAIT. In spectrum(): Q = scipy.linalg.toeplitz(q) where q = stiffness_first_col(n_elem, h) with n_elem = 1200, so q has length 1199, matrix 1199×1199 ✔ fine. Hmm, let me just recompute the eigenvalues directly right now and look at the FULL bottom. Maybe eigvalsh with subset_by_index and generalized has a bug in scipy 1.18?? Test earlier with random matrices returned empty for full call too — that was due to empty Z. Let me now test eigvalsh on the actual Qz, Mz with full spectrum and check min.

The symbol ranges ±0.06, so true generalized eigenvalues should reach ±10 — the computed −1e-4 cluster contradicts even the unconstrained bounds. The eigenvalue solve itself must be misbehaving. Testing directly.

The mpmath quad over infinite interval with digamma of complex argument is slow. Restrict integration range: hhat decays like e^{−τ²/2}, integrate [−20, 20] — plenty. Also the sieve over 10^6 with inner while loop is slowish but OK (~seconds). The timeout likely from mp.quad with complex digamma over infinite range at dps 30. Reduce dps to 20 and range [−15,15].

Retrying with bounded integration range and lower precision.

Rewrite the S-computation section. Replace S_sing/S_table with direct piecewise Gauss-Legendre quadrature of g. Keep the table-based path? No — replace entirely. Keep brute_force_entry for the check (it uses G_TAB — table; that introduces table noise into the CHECK... the check tolerance 1e-3 — fine, brute force is independent path). Plan the new code: ```python # von Mangoldt + cumsums (as in E-009a) def mangoldt_sieve... N_MAXG = int(np.exp(10.0)) + 2 # T_MAXG global = 10 ... def g_float(t): # vectorized numpy, t >= 0 array t = np.asarray(t, float) g = -4*(np.exp(t/2)+np.exp(-t/2)-2) g += prime_sum_vec(t) g += DIG_COEFF * t # digamma coeff precomputed # lerch combination out = np.empty_like(t) fast = t > 0.35 if fast.any(): z = np.exp(-2*t[fast]) out[fast] = -0.25*(PHI1 - np.exp(-t[fast]/2)*lerch_phi2_fast(z)) if (~fast).any(): mp.dps = 25 for i in np.flatnonzero(~fast): ti = mp.mpf(float(t[i])) out[i] = float(-0.25*(mp.lerchphi(1,2,mp.mpf(1)/4) - mp.exp(-ti/2)*mp.lerchphi(mp.exp(-2*ti),2,mp.mpf(1)/4))) g += out g[t == 0] = 0.0 return g ``` Gauss-Legendre: use numpy.polynomial.legendre.leggauss(12). def S_exact(k, h): window [lo,hi] = [(k-1)h, (k+1)h] for k>=1; k=0 special. kinks = log n for n with lo < log n < hi: n from ceil(exp(lo)) to floor(exp(hi)). sub-intervals; GL nodes: x = mid + half*nodes; weights. integrand: (h - |s|) g(t) with s = t - kh: weight = h - |t - kh|. return sum. For k=0: 2*∫₀^h (h−t)g(t)dt with kinks log n in (0,h): n=2 if h > log2 (h≤0.01 < 0.693, so no kinks for our h values; but log n for n=2.. at h=0.01: none ✔). Still handle generally. Vectorize: gather all GL nodes across sub-intervals, single g_float call per S(k)... or even batch across all k? Number of nodes total ~ N_k × ~60 = 120k — batch per k is fine (2000 calls of g_float on ~60 points each — plus mpmath for t<0.35 nodes: nodes with t ≤ 0.35 occur only for k ≤ 70 (h=0.005): 70×60 = 4200 mpmath lerchphi — each ~1ms → ~5s per config. Acceptable. But wait — mpmath lerchphi caching: for repeated configs (h-convergence), recompute each time; fine. Update the checks: - entries_vs_brute_force stays (tolerance 1e-3; brute force from table — the table itself is the noisy element; the check now compares accurate vs table-brute-force — expect ~1e-6-level relative differences on small entries... q entries ~0.011 for k=0: table noise 1e-6 abs → rel 1e-4 ✔ passes 1e-3). - positivity: min generalized eigenvalue ≥ −1e-7 (documented noise floor). Actually with accurate S, expect ≥ −1e-9. Set check: min_eig > -1e-7 and report value. - Also add check: v^T Q v for the sin test function ≈ 2.437e-4 (the zero-side value) — a strong absolute validation! tolerance 1e-6 relative... Q form value from matrix: 2.434e-4 matched zero side to 1.2e-3 relative. Set tol 2e-3 relative. Rewrite the whole script file for cleanliness. Keep structure/conventions. Also update description/caveats. Also record the sin-test Rayleigh value in key_values. One more thing: eigenvalues expected ~1e-6-ish bottom — the interesting output is λ_1(a) trend. And compare with log(1/a)+O(1) (Thm 1.4) — record. Let me rewrite the file now.

Rewriting the script with exact piecewise-quadrature S(k) and an absolute validation check against the known Weil-form value.

MUCH worse — eigenvalues now −9.5 at a=3 and diverging with refinement (−3.2 → −9.5 → −37)! And vᵀQv = 7.3e-5 vs expected 2.44e-4. So the new S(k) is WRONG — worse than the table version. Bug in my new quadrature. Let me check S(k) against the mpmath reference from before: exact S(0) = −9.8352771288e-08, S(1) = −2.3766064586e-07 etc. Possible bugs: 1. k=0 case: I integrate (h−xs)·g over [0,h] then double ✔. pts for k=0: [0, h] (no kinks since h < log 2 ✔). 2. k≥1: weight (h − |xs − kh|) ✔ triangle. 3. Kink computation: n_lo = ceil(exp(lo)), n_hi = floor(exp(hi)); for n in range(max(n_lo,2), n_hi+1) if lo < log n < hi. OK. 4. g_float: DIG_COEFF sign: −(|t|/2)(ψ(1/4) − logπ) = +2.686t. DIG_COEFF = float(−(digamma(1/4) − log π)/2) = −(−5.372)/2 = +2.686 ✔. 5. lerch_comb: −0.25*(PHI1 − e^{−t/2}Φ(e^{−2t})) ✔. Wait — the mpmath reference g_mp earlier gave S exact values which the OLD code matched to 3.6e-12. Let me test the NEW g_float against g_mp at a few points — maybe a bug in g_float (e.g., lerch fast series). Test at t = 0.1 (slow path), 1.0, 3.7, 10 (fast path).

Worse — the new quadrature path has a bug. Testing new `g_float` against the mpmath reference directly.

g_float is perfect. But S(k) for k ≥ 1 has errors ~1.3e-9 — way bigger than the table version (3.6e-12). The k≥1 quadrature must be mishandling something. Note S(0) is fine (1.3e-12). For k≥1 the window [lo,hi] = [(k−1)h,(k+1)h] with kinks — error 1.3e-9 suggests kink handling or... wait: for k=1, h=0.005: window [0.005, 0.015], no kinks (log 2 = 0.69). So no kink issue at k=1,2. Error 1.29e-9 — from GL quadrature of a SMOOTH function?? 12-pt GL on a smooth function should be spectral. UNLESS the weight (h − |xs − kh|) has its kink at xs = kh INSIDE the sub-interval [lo, hi] and I didn't split there!! The triangle weight peaks at t = kh — a kink in the INTEGRAND at t = kh. GL over [lo, hi] straddling the kink → slow convergence. Fix: split at t = kh as well: pts include kh. Sub-intervals [lo, kh], [kh, hi] plus kinks. That's the bug. Fix: pts = sorted set {lo, kh, hi} ∪ kinks.

Found it: the triangle weight has its own kink at t = kh, and I didn't split the quadrature there — GL straddles a non-smooth point. Splitting at kh too.

The PDFs: 2606.09096v1.pdf (Suzuki), 2602.04022v1.pdf (Connes survey), proof-riemann-2017-04.pdf, ssrn-4909306.pdf — downloaded during earlier sessions for reference. They're research resources; include them in the commit (they're part of the working archive). Let me stage everything relevant and commit.

Previous commits used "NGUYEN-RH-1 <research@local>" — but no user.name/email in local or global config now (weird — maybe previous sessions set it per-command via -c flags). I can commit with per-command identity (git -c user.name=... -c user.email=... commit) — that doesn't modify config, consistent with the rules and with prior session behavior.

Previous commits used identity `NGUYEN-RH-1 <research@local>` via per-command flags (config untouched). Doing the same.

Done. Now present the fork per §8.4a. The fork rule says do ALL forks one by one — user directive. So strictly, I don't need to ask which; I should proceed with all in order, then gather thoughts. But presenting the plan and letting the user reorder/redirect is appropriate at a natural pause, especially given the effort involved. The rule says "do ALL of them — one by one — then pause to gather thoughts and evaluate the next step together." So the user has already decided: do all forks. I could just proceed with E-010. But a brief status + confirmation of order is reasonable since E-010 has a design subtlety (θ choice, λ shift). Actually per the directive, don't ask permission — proceed. But session pacing §8.5 says ask before long runs. E-010 is a focused sub-stage (~30-60 min). I'll summarize and proceed with E-010 unless the user objects... The user asked "let me know what is next" — they may want to just hear it. I've now done substantial work. Best: report status and the fork, and since the fork rule mandates doing all, state I'm proceeding with E-010 first unless they reorder. Given interactive session norms and the effort already spent, I'll present and ask — the fork rule says paths aren't dropped by choice, but order/timing can be confirmed. Actually the rule is explicit: do all, then pause to gather thoughts TOGETHER after. So proceed now with E-010. But it's also fine to give the user the chance to weigh in at this natural break. I'll present the summary and start E-010 directly — that's what the standing directives say. Hmm, but my message turnaround: the user said "let me know what is next" — minimal expectation is an answer. I've done a whole sub-stage. I'll report and proceed with E-010 in the next turn unless told otherwise. Actually — continuing to work right now without pause is fine too. But context/time: significant work done; a natural sub-stage boundary. I'll report concisely and begin E-010 scoping in the same turn? Better to report and let user respond, since E-010 is a new sub-stage and session pacing is user's call. Given §8.5 (break prompt), I'll summarize and ask whether to continue with E-010 now.

Session 003 state is committed (`ead7865`). Summary of this sub-stage: **E-009a — Suzuki's screw function g(t)**: implemented in mpmath, validated against eq. 2.2 to 25 digits (A = 0.7075463657, r(t)/t² → −0.8750599754), tabulated on [0,10]. **E-009b — Galerkin spectrum of the Weil-form operator A_a**: eventful but conclusive: - First version showed spurious *negative* bottom eigenvalues — a fake ¬RH signal caused by 1/h² amplification of table-interpolation noise (lesson logged, D-019 F3). Fixed with exact piecewise Gauss–Legendre quadrature (S(k) exact to ≤1e-15). - **Absolute validation**: vᵀQv = 2.437005e-4 vs zero-side 2Σ|v̂(γ)|² = 2.437016e-4 — the discrete form *is* the Weil form. - En route: machine-verified the Weil explicit-formula conventions (Gaussian test closes to 9e-16; note the arXiv HTML's Λ(n)/n is wrong for our conventions — Λ(n)/√n validated; logged D-001 NT-1). - **λ_a cliff**: bottom eigenvalue 0.414 at a=0.25 → 2e-4 at 0.5 → ≤1.4e-9 at a=1 → ≤1.7e-12 at a=5, all positive — consistent with Yoshida (λ_a > 0 ∀a ⟺ RH) and independently reproduces Kim et al.'s "positive, superexponentially decaying" report. - Key structural finding: A_a's spectrum is *not* the zeta spectrum; the zeta-aligned operator is 𝒟̄_{a,θ} whose eigenvalues are zeros of W(a,θ;z) (eq. 1.11) — computable with our machinery. **D-019** filed: analysis + Q-S1 verdict (L²→uniform gap is the W2-shaped wall; an entire-type + Hurwitz lifting route is the lead Phase-4 candidate) + E-010 design. **Fork point (§8.4a)** — all four to be explored, order up for confirmation: 1. **E-010**: compute W(a,θ;z) via deficiency vectors v_± (solve (Q−λM)c = b_±), find its real zeros for a ∈ {2,4,6,8} and scan θ — direct test of convergence toward γ₁, γ₂, ... (Suzuki line continuation) 2. **3.2 cont.**: prime-side Li coefficients (Bombieri–Lagarias exact formulas), push past n=116 3. **3.3**: de Bruijn–Newman heat flow vs the 2/3 density 4. **T4**: ξ′-analogue (cheap secondary Track A target) Shall I start E-010 now, or would you rather reorder/take a break?

Proceed with E-010: compute W(a,θ;z) and its zeros. Design from D-019 §4: - Deficiency vectors v_± solve (T_a v_±)(x) = e^{±x} where T_a = A_a − λI, λ < λ_a. - W(a,θ;z) = (z−i)∫_{-a}^{a} v₊(a,x) e^{izx} dx + e^{iθ}(z+i) ∫_{-a}^{a} v₋(a,x) e^{izx} dx. - v_± normalized so their T_a-norms agree. - Eigenvalues of 𝒟̄_{a,θ} = zeros of W; all real (Thm 1.5). - Cor 1.6: convergence to z²ξ(½−iz)/ξ′(½−iz) as a→∞. Numerical plan: 1. Solve (Q − λM)c = b_± in the Galerkin space, b_±,i = ⟨e^{±x}, φ_i⟩ (exact integral over hat support). λ shift: need λ < λ_a; λ_a > 0 tiny — choose λ = −1 (safely below). 2. v_±(x) = Σ c_i φ_i(x). Compute Fourier integrals ∫v_±(x)e^{izx}dx analytically from hat coefficients: ∫φ_i e^{izx}dx known closed form (hat transform = h·sinc²-ish): ∫φ_i(x)e^{izx}dx = e^{izx_i}·(2−2cos(zh))/(z²h) = e^{izx_i}·h·sinc²(zh/2)-ish with sinc(θ)=sin θ/θ. So ∫v e^{izx} = Σc_i e^{izx_i}·(2−2cos(zh))/(z²h). 3. Normalize: T_a-norms: ‖v‖²_T = cᵀ(Q − λM)c = cᵀb (since (Q−λM)c = b). Scale v_₋ so ‖v_₋‖_T = ‖v₊‖_T. 4. W(z) on a real grid z ∈ [0, 60] (first ~12 zeros), for several θ; find sign changes → zeros. W is complex for real z? Zeros of W are real (Thm 1.5) but W itself complex-valued on ℝ... For finding real zeros, need |W| or a real gauge. Hmm: W(a,θ;z) for real z is complex in general. Zeros on the real line can be found as minima of |W|². Alternatively note e^{-iθ/2}W might be real-valued on ℝ by symmetry: v_₋(x) = v₊(−x)? Since T_a is even (g even) and e^{−x} = e^{+(−x)}: v₋(x) = v₊(−x) ✔. Then ∫v₋e^{izx} = ∫v₊(−x)e^{izx}dx = ∫v₊(x)e^{−izx}dx = conj of ∫v₊e^{izx} for real z (v real). So with V(z) := ∫v₊e^{izx}dx: W(z) = (z−i)V(z) + e^{iθ}(z+i)V̄(z) for real z. Write V = V_r + iV_i: (z−i)V + e^{iθ}(z+i)V̄. For θ = 0: W = (z−i)V + (z+i)V̄ = z(V+V̄) − i(V − V̄) = 2zV_r + 2V_i·... compute: (z−i)(V_r+iV_i) = zV_r + izV_i − iV_r + V_i; (z+i)(V_r−iV_i) = zV_r − izV_i + iV_r + V_i. Sum: 2zV_r + 2V_i. REAL ✔. So θ=0 gives real W on ℝ — zeros found by sign changes. Great: scan θ ∈ {0, π/4, π/2, ...} with real gauge e^{-iθ/2}W? For general θ: e^{-iθ/2}W = e^{-iθ/2}(z−i)V + e^{iθ/2}(z+i)V̄ — not real for θ≠0. For zero-finding at general θ use |W| minima... but Thm 1.5 says all zeros real, so |W| touches 0 on ℝ. Simpler: work with θ = 0 primarily (some extension), maybe also θ = π (W = (z−i)V − (z+i)V̄ = −2V_i·z... let me compute: (z−i)V − (z+i)V̄ = [zV_r + izV_i − iV_r + V_i] − [zV_r − izV_i + iV_r + V_i] = 2izV_i − 2iV_r = 2i(zV_i − V_r) — pure imaginary; W/i real ✔. So plan: compute W for θ=0 on z-grid, sign changes, bisect, get zeros z_j(a, θ=0) for a ∈ {2,4,6,8}; compare to γ_j. Also maybe a couple more θ values. But WAIT — is θ=0's extension the "zeta-aligned" one? Unknown (Q-S3). The numerical experiment will show whether zeros approach γ for any θ. Start with θ=0. Also domain/mean-zero subtlety: A_a acts on L²₀; e^{±x} is not mean-zero — the resolvent solve (T_a v = e^{±x}) in L²₀: project rhs? T_a is invertible on L²₀; the equation (T_a v_±)(x) = e^{±x} in the L²₀ sense means T_a v_± = P_a(e^{±x}) presumably, or e^{±x} restricted... The paper's Lemma 6.2 states (T_a v_±)(x) = e^{±x}. If T_a maps into L²₀, the rhs should be P_a e^{±x}. Hmm — or the equation holds in the distributional sense on the whole L². To be safe, solve with rhs = P_a(e^{±x}) (projected) — check sensitivity later. Actually simplest: build rhs b_±,i = ⟨e^{±x}, φ_i⟩ and solve the constrained system (Z-projected): (Zᵀ(Q−λM)Z)d = Zᵀb — this automatically uses the projected rhs. Fine. Also λ shift: T_a = A_a − λI with λ < λ_a ≈ 0⁺. Choose λ = −1. Sensitivity check: λ = −0.5 vs −1 vs −2 at one (a, θ) — the zeros of W should be INDEPENDENT of λ (different λ gives different realization of same extensions? The extension domains depend on λ via v_±... the theory: deficiency vectors of 𝒟_a in ℋ(T_a) depend on λ, but the operators 𝒟̄_{a,θ} and their spectra should be λ-independent... actually the Hilbert space ℋ(T_a) itself depends on λ (norm changes), and the extensions' spectra could depend on λ?! Hmm, in the paper's construction the operator 𝒟̄ is in ℋ(T_a); changing λ changes the inner product and hence self-adjointness conditions. The W-function zeros should still be the spectra of the corresponding extensions. For the RH correspondence, maybe any λ works and Cor 1.6's θ(a), φ absorb it. Numerically: test λ-sensitivity. If zeros depend on λ, that's a Q-S3-type question to document. Also the mean-zero constraint in our Galerkin space: our Q, M act on mean-zero subspace — matches L²₀ setting ✔. Mesh: a up to 8 ⇒ need g on [0,16] — E-009a table only goes to 10! But E-009b's g_float computes g directly (sieve to e^10). For a=8 need T_MAXG=16 ⇒ sieve to e^16 ≈ 8.9e6 — fine memory-wise (float arrays 8.9M × 8B × few = ~300MB, OK) but sieve loop over 8.9M in Python ~ slow (the is_comp slicing sieve is OK: ~seconds; the prime-power while loop fine). g_float evaluation count: S(k) for N = 2a/h = 3200 elements × ~60 GL pts ≈ 200k evals vectorized ✔ fast. mpmath lerch only for t<0.35 ✔. Hmm wait, also for a=8, h=0.005: N=3200, dense eigh... we don't need full eigensolve for E-010 — only the resolvent solve (Q−λM)c = b: dense Cholesky on 3200² — fine (few seconds). But building Q requires S(k) for k up to N — 3200 × 60 g-evals = 200k — fine. Refinement: h=0.005 for all a? For a=8, maybe h=0.01 for speed first pass. Convergence check at one a. Plan the script E-010-suzuki-W-function.py: - Reuse E-009b's g/S/stiffness via import? The scripts are standalone; importing from another script is doable via importlib but cleaner to copy the needed functions (self-contained convention per archive). Copy g_float/S/stiffness code with T_MAXG=16. - For each a ∈ {2,4,6,8} (h=0.005; h-conv at a=4 with h=0.01, 0.002): - Build Q, M (toeplitz), Z projection (mean-zero). - T = Zᵀ(Q−λM)Z; rhs b_± = Zᵀ(⟨e^{±x},φ_i⟩); solve. - ⟨e^{sx}, φ_i⟩ exact: ∫_{x_{i−1}}^{x_i} e^{sx}(x−x_{i−1})/h dx + ∫_{x_i}^{x_{i+1}} e^{sx}(x_{i+1}−x)/h dx. Closed form: e^{sx_i}(e^{sh}−1−sh·... let me just: ∫_{-h}^{0} e^{s(x_i+u)}(u+h)/h du + ∫_0^h e^{s(x_i+u)}(h−u)/h du = e^{sx_i}·[(e^{sh}+e^{−sh}−2)/(s²h)]·... verify: ∫_0^h e^{su}(h−u)/h du = [e^{su}(...)]... formula: ∫_0^h e^{su}(h−u)du/h = (e^{sh} − 1 − sh)/(s²h)·... compute: ∫₀^h e^{su}(h−u)du = h(e^{sh}−1)/s − [e^{su}(su−1)/s²]₀^h = h(e^{sh}−1)/s − (e^{sh}(sh−1)+1)/s². Divide by h. Similarly the other side. Fine — or just numerical quadrature (GL 8-pt per element, exact enough). Simpler: use quadrature. - ‖v_±‖²_T = c_±ᵀ(Q−λM)c_± (in reduced coords d: dᵀT d). Normalize. - V(z) = ∫v₊ e^{izx}dx = Σ_i c_i e^{izx_i}·hatFT(z), hatFT(z) = (2−2cos(zh))/(z²h) (with hatFT(0)=h). - W(z;θ=0) = 2z Re V(z) + 2 Im V(z)·... wait derived above: W(θ=0) = 2zV_r + 2V_i?? Let me recheck: (z−i)V + (z+i)V̄ where V = V_r + iV_i: (z−i)(V_r+iV_i) = zV_r + izV_i − iV_r − i²V_i = zV_r + V_i + i(zV_i − V_r). (z+i)V̄ = (z+i)(V_r−iV_i) = zV_r − izV_i + iV_r + V_i = zV_r + V_i + i(V_r − zV_i). Sum = 2zV_r + 2V_i. Imag parts cancel ✔. So W₀(z) = 2(z ReV(z) + ImV(z)). - Sign-change scan + bisection on z ∈ (0, 60]. - Compare zeros with γ_1..γ_10. - λ-sensitivity: λ ∈ {−0.5, −1, −2} at a=4, θ=0. - θ-sensitivity: θ ∈ {0, π/2, π} at a=4: for θ=π/2 use |W| minima... or compute all and find real zeros via |W|² local minima → polish with Newton on complex plane? Keep simple: θ=0 main; θ=π also real-gauge (W/i); θ=π/2 via |W| minima (report only). Checks: - W real-gauge for θ=0: |Im part| tiny (automatically real by construction — verify the identity numerically: compute W full and check Im ≈ 0). - Zeros real & stable under h refinement at a=4. - λ-independence documented. Output: CSV with a, h, lambda_shift, theta, j, z_j, gamma_j, z_j/gamma_j. Effort: moderate. One concern: does the zeta-aligned limit actually show zeros near γ at these small a? Probably NOT close — a≤8 is small; the Cor 1.6 limit is a→∞. What we hope to see: zeros of W moving TOWARD γ's as a grows, or at least structured behavior. Even negative result (no approach) is informative for Q-S3. Also worth computing: bottom eigenvalues of 𝒟̄ vs... whatever the data shows. Let me also double-check the v_± equation: "(T_a v_±)(x) = e^{±x}" — from the earlier fetch: "deficiency vectors v_± satisfying (T_a v_±)(x) = e^{±x}". ✔. And normalization: "normalized so their T_a-norms agree" — after solving, scale v_₋ by ‖v₊‖_T/‖v₋‖_T. By symmetry v₋(x) = v₊(−x) ⇒ norms automatically agree (T_a norm is even-symmetric: g even, λ scalar ⇒ ‖v₊‖_T = ‖v₋‖_T exactly up to discretization). Good. Write the script. Reuse code by copying from E-009b (self-contained). Set T_MAXG = 16. For the e^{±x} rhs with quadrature: b_i = ⟨e^{sx}, φ_i⟩ — GL 8-pt on the two elements of the hat support. Vectorized. For the solve: T_red = Zᵀ(Q−λM)Z dense n−2 square; a=8, h=0.005: n=3199 → dense 3197² solve ~ 1-2 s ✔. But building Z (QR of ones) for n=3199: Z is 3199×3198 dense — np.linalg.qr complete of (3199,1): Householder-based, produces full Q 3199×3199 — that's fine memory (82MB) and time (a few seconds?). QR of n×1 with complete mode: LAPACK dgeqrf on n×1 then dorgqr for full n×n — O(n³)? dorgqr generation of full Q from 1 reflector is O(n²)... should be OK. Alternative cheaper constraint handling: since Z is only needed for projection, could solve bordered system: [T e; eᵀ 0][c; μ] = [b; 0]. That avoids forming Z! T = Q−λM (n×n), e = ones. Solve (n+1)×(n+1). Much cheaper. And the reduced eigen... we don't need eigensolves here at all! Great: bordered solve. But wait: T = Q−λM restricted to mean-zero must be invertible — bordered system handles it. V(z) from c (hat coeffs, now including the constraint satisfaction ✔). Alright, also the W zeros: scan z ∈ [0.01, 60] with 20000 points, sign changes of W₀, bisect. Let me write it. Also include h-convergence: a=4 at h ∈ {0.01, 0.005, 0.0025}? h must satisfy... S(k) quadrature works for any h (no table divisibility constraint anymore!) ✔ any h fine. Runtime estimate: per config: S(k) computation ~ N×(sub-intervals×12) g-evals. At a=8: N=3200, ~70 pts each ⇒ 224k g_float evals — vectorized per S call: each S(k) calls g_float on ~60 points; overhead per call ~ microseconds-ms; 3200 calls × (prime searchsorted etc.) — each g_float call has fixed overhead ~0.5ms ⇒ ~2-3 s. Plus mpmath lerch for small-t nodes (k ≤ 70): 70×60=4200 mpmath evals ~ 30-60s? Hmm — lerchphi at dps 25 maybe 2-5ms each ⇒ 4200×3ms = 13s. OK. Configs: 4 a-values + 2 extra h + 2 extra λ + θ variations reuse same v_± (W cheap). Total ~ 7 configs × ~20s = 2.5 min. Fine. One more design point: z range. γ_1 = 14.13. At a=2..8, will W have zeros anywhere near 14? Unknown — scan [0, 60] covers first 12 zeros. Also scan behavior: number of zeros found vs expected. Write the script now. Also add check: W θ=0 imaginary gauge ~ 0; v_− symmetry: c_₋ reversed ≈ c_₊.

Proceeding with E-010 per the fork rule. Setting up tasks.

Wait — there's an issue with the θ≠0,π branch: W uses V from cp only, but for generic θ the W needs BOTH v₊ and v₋ Fourier integrals: W = (z−i)V₊ + e^{iθ}(z+i)V₋ with V₋(z) = ∫v₋e^{izx} = V₊(−z) = conj(V₊(z)) for real z ✔ — so W_real(z, V, θ) with V = V₊(z) and conj(V) = V₋(z) is correct for real z ✔. In the generic-θ minimize_scalar call I pass V computed from cp ✔ and W_real uses np.conj(V) for the v₋ part ✔ good. But in zeros_for, for generic θ I compute Vm but never use it in Wf — I use W_real formula... no wait, I compute Wf = |(z−1j)Vp + e^{iθ}(z+1j)Vm| using Vm — but Vm should equal conj(Vp) for real z. Since cm was rescaled but remains reversed-cp, Vm = conj(Vp)·(real scale). Both fine. Actually there's redundancy but harmless. Bug check in zeros_for generic theta minimize_scalar: I call W_real(z, V_scalar, theta) where W_real signature (z, V, theta): (z−1j)*V + e^{iθ}(z+1j)*conj(V) — with z scalar np.float64, V scalar complex ✔. The residual threshold: resid < 1e-3*max(1, max|Wf|) — max|Wf| over grid could be large; minima of |W| at true zeros ≈ 0 exactly (Thm 1.5). OK. Also for θ=0 brentq refine with r ± 0.02 — if root spacing < 0.04 could bracket wrong root; zeros spacing ~5+, fine. One more concern: deficiency solve — T must be nonsingular on the constrained subspace: T = Q − λM with λ = −1: Q ⪰ ~0, M ≻ 0 ⇒ T = Q + M ≻ 0 ✔ definite. For λ = −0.5, −2 also fine. Efficiency: a=8, h=0.005: n = 3199; bordered solve 3200² — scipy dense solve ~10-20s. Q toeplitz build: S(k) for 3200 k's, each quad over ~[5-15 sub-intervals × 12 pts] — each S maybe 1-3ms → 3200 × 2ms = 6s? plus g_float overhead. OK. Potential problem: at a=8, the sieve N_MAXG = e^16 ≈ 8.9M — sieve time? The is_comp slicing loop over primes up to 8.9M: ~660k primes... loop 8.9M iterations in Python for the while pk loop? No — the outer loop is range(2, N+1) = 8.9M iterations checking is_comp[p] — pure Python loop 8.9M ~ 5-10s. Prime-power inner loops small. Total maybe 15s. Acceptable. Memory: is_comp bool 8.9MB, lam_log 71MB, LOGS/LAM/C1/C0 4×71MB = 284MB ✔. Also — mpmath lerchphi calls: t ≤ 0.35 nodes: for h=0.005, k ≤ 70: ~70 S(k) × ~5 sub-intervals × 12 = 4200 evals × ~2ms = 8s. OK. Run it. First quick smoke test: only run with small settings? Just run full — but risk of runtime bugs at later configs wasting time. Do a quick smoke test of zeros_for at a=2 first via inline import.

Quick smoke test at a=2 before the full run.

The refine step `brentq(Wdirect, r−0.02, r+0.02)` fails when the interpolated root r is closer than 0.02 to the true root and Wdirect at r±0.02... should still have sign change unless the bracket doesn't straddle. Wdirect is the exact evaluation; the interp root r approximates the true root to grid accuracy (0.003); r±0.02 should straddle unless the sign-change detection from interp gave a false bracket (e.g., even multiplicity tangency — sign doesn't change... but then it wouldn't be in idx). Or Wdirect differs from interp enough near the bracket ends. Safer: use the grid bracket (zg[i], zg[i+1]) directly with Wdirect.

The refinement bracket is too narrow. Use the original grid bracket instead.

OPERATIONS\n### 6.1 Session-start protocol (website work)\n1. Read this file.\n2. Run `./.venv/Scripts/python.exe web/healthcheck.py --restart`\n   (checks /api/health + all routes + status-API freshness; restarts the\n   server if unreachable). Fix any failing route before other work.\n3. Check the watchdog is alive: `web/logs/watchdog.log` tail should show\n   entries within the last ~10 min; if not, restart it (\u00a76.2b).\n4. Review new feedback: `web/feedback.db` status='new' (or the /feedback/\n   page); surface relevant items to the user.\n5. Improvement pass (standing order, user 2026-08-19): look for at least\n   one interface or data-presentation improvement per session; log ideas\n   in \u00a78 below and implement the worthwhile ones.\n### 6.2 Start server (detached, sandbox DISABLED \u2014 long-run rule)\n```\ncd D:\\Python\\Quantum && ./.venv/Scripts/python.exe web/manage.py runserver \\\n  127.0.0.1:8001 >> web/logs/server.log 2>&1   # DETACHED_PROCESS\n```\n### 6.2b Watchdog (always-on monitoring, started 2026-08-19)\n`web/watchdog.py` runs detached between sessions: every 300 s it runs the\nhealth checks and restarts the server if unreachable. Logs:\n`web/logs/watchdog.log` + `web/logs/healthcheck.log`.\nStart detached: `subprocess.Popen([sys.executable, 'web/watchdog.py'], ...)`\nwith DETACHED_PROCESS (same pattern as \u00a76.2).\n### 6.3 Restart / health\n- Stop: find PID via `netstat -ano | findstr :8001`, `taskkill /PID <pid> /F`.\n- **Restart required after ANY code OR template change** (templates are\n  cached in-process \u2014 a home.html edit did not appear until restart,\n  2026-08-19). Static CSS/JS changes serve immediately.\n  NOTE: port is **8001** since 2026-08-19 \u2014 port 8000 is reserved for the\n  user's other service (do not use it).\n- Log tail: `web/logs/server.log`.\n- First run after code change to models:\n  `./.venv/Scripts/python.exe web/manage.py migrate`.\n### 6.4 Updating the site when research data changes shape\n- New experiment: automatic (db + sidecars). Charts: add entry to\n  `research_data.CHARTS` (x/y columns, type).\n- New markdown folders: register in `research_data.MD_COLLECTIONS`.\n- Never patch around \u00a70 \u2014 if a feature needs research-archive writes,\n  STOP and ask the user.\n### 6.5 Lock-safety guarantees (verified 2026-08-19, web/lockcheck.py)\n- Text/md/CSV/log reads use Python 'r' handles (Windows share mode allows\n  concurrent writers) and close immediately after each read.\n- research.db / agent.db opened SQLite mode=ro per query, closed in finally;\n  shared read lock exists only for the duration of each SELECT (ms).\n- Server runs --noreload: no autoreload file watchers held open.\n- git log is read-only plumbing (no index lock).\n- Empirical: 24 s of 4-thread HTTP load across all heavy pages while taking\n  120 DB write locks (BEGIN IMMEDIATE/ROLLBACK) + 360 write-intent file\n  opens on STATE.md, NGUYEN.md, CSVs, run-logs \u2014 zero conflicts, zero stalls.\n\n## 7. IMPROVEMENT BACKLOG (standing order \u2014 review each session)\nIdeas not yet implemented, ranked by value:\n1. Conversations: \"new activity\" badge when agent.db grows between polls.\n2. Experiments: diff view when a sidecar's checks change between runs.\n3. Charts: E-019 zero-flow needs series-column grouping support.\nDone:\n- 2026-08-27: Scripts & Data page `/scripts/` (user request) \u2014 index of all\n  45 research/numerics/scripts/*.py with their experiment links + data\n  files; detail pages render each CSV as a spreadsheet table (500-row\n  server-side pagination, sticky header, sticky row-number gutter with\n  true CSV line numbers, numeric-column right-align, hover stripes) and\n  each JSON sidecar as a collapsible pretty-printed block. Script\u2192data\n  mapping = experiments-table links \u222a exact-stem matches (verified: all\n  45 scripts resolve correctly; utility scripts show \"none registered\").\n  Routes added to healthcheck (now 24); traversal guard verified 404.\n- 2026-08-27: mobile/responsive sidebar (backlog #3) \u2014 at \u2264 900px the\n  sidebar goes off-canvas (translateX transition) behind a hamburger\n  button in the sticky topbar; backdrop tap, Escape, or any menu-link\n  click closes it; state is body.nav-open (aria-expanded wired);\n  content padding shrinks to 16px. Desktop layout unchanged.\n- 2026-08-27: dashboard + home stat counters auto-refresh (backlog #4) \u2014\n  /api/status/ now carries summary_stats(); app.js updates all counters\n  (dashboard: done/partial/open/results/experiments/feedback; home: done/\n  results/experiments/derivations/graveyard/sessions) every 3 s, and\n  rebuilds the dashboard phases table on change only (signature compare,\n  DOM-API build \u2014 no innerHTML). Static git-feed / recent-sessions tables\n  intentionally left server-rendered.\n- 2026-08-27: global search page `/search/` (backlog #1) \u2014 AND-of-terms\n  case-insensitive scan-on-query across all MD_COLLECTIONS markdown\n  (results/derivations/graveyard/journal/resources); up to 3 snippets per\n  file with line numbers + <mark> highlights; results hits mapped to\n  /ledger/R-NNN/; 100-file cap with truncation notice; sidebar entry;\n  /search/ + a sample query added to the healthcheck ROUTES (now 22).\n  Also: watchdog found dead (last log 2026-08-21) and respawned detached.\n- 2026-08-19: healthcheck.py + watchdog.py (\u00a76.1/\u00a76.2b); Home latest-result\n  card now dynamic (was hardcoded R-004); dashboard data-freshness line\n  (STATE.md/research.db/agent.db, live via polling); E-017 chart.\n- 2026-08-22: bug fixes. (1) git_log 500 on /dashboard/ \u2014 subprocess\n  decoded git's UTF-8 commit output as cp1252; reader thread died on\n  Unicode commit messages and stdout came back None. Fixed with\n  encoding=\"utf-8\", errors=\"replace\" + a None guard. (2) Roadmap Phase 2 /\n  5B checklists rendered as paragraph text \u2014 those phases have a note\n  paragraph directly above the list (no blank line) and python-markdown\n  never lets a list interrupt a paragraph (sane_lists or not). Fixed with\n  research_data._restore_interrupted_lists: inserts the missing blank line\n  before a list that follows paragraph text (skips indented item\n  continuations so existing lists stay tight; skips fenced code). Archive\n  text rendered verbatim as before \u2014 block structure only.\n- 2026-08-20: math typography pass APPLIED then REVERTED same day (user\n  directive). Context: MathJax 3.2.2 works (resources atlas has real\n  LaTeX); the research archive writes plain Unicode math, so MathJax has\n  nothing to typeset there \u2014 that is the correct, intended rendering.\n  A display-formula-lifting heuristic (research_data._display_formulas +\n  .math-line styling) was built and then removed at user request:\n  **the website renders the research archive VERBATIM \u2014 no presentation\n  transforms, no conversions, no re-boxing of archive text.** Do not\n  re-attempt Unicode\u2192LaTeX conversion or formula-detection heuristics;\n  the archive's plain-Unicode math is the source of truth and its\n  verbatim display is correct by definition.\n\n## 8. BUILD STATUS\n- [x] Plan written (v1.0, 2026-08-19)\n- [x] Dependencies installed (Django 6.1, markdown 3.10.3); vendored JS\n      (plotly 2.35.2, MathJax 3.2.2 tex-chtml)\n- [x] Django scaffold (rhweb project + dashboard app)\n- [x] Parsers / views / API (research_data.py read-only layer)\n- [x] Templates / CSS / JS (12 pages, sidebar, 3 s polling, Plotly charts)\n- [x] Server verified live at 127.0.0.1:8001 \u2014 all 15 routes 200;\n      feedback POST/search verified; path-traversal guard verified;\n      smoke-test data cleaned up\n- [x] Initial commit (web/ + RH-WEBSITE.md only)\n",

T-norms agree to 1e-14 ✔, symmetry 6e-14 ✔. But zeros: [] — no sign changes found, and a ComplexWarning: casting complex to real — `float(np.exp(1j*z*x) @ cp)` — cp is real so the dot is complex; float() on complex discards imag with warning. Should use complex(...) not float(...). Let me check: np.exp(1j*z*x) @ cp is a complex scalar; float() discards imaginary (which is fine mathematically? NO — we need the full complex V(z) = hatFT · Σc_i e^{izx_i} — the imaginary part is essential!). float() takes only the real part — BUG. Fix: V = hat_FT(...)[0] * (np.exp(1j*z*x) @ cp) — keep complex. That explains zero roots: W computed from Re(V) only — garbage. Fix Wdirect.

Bug: `float()` on a complex inner product discards the imaginary part of V — which is essential. Fixing.

Timed out at 10 min — the run is too slow. Bottlenecks: sieve to 8.9M in pure Python (the while-loop over prime powers plus the outer Python loop over 8.9M) — that printed, so sieve finished? "sieving..." printed at start; nothing after. The smoke tests completed the sieve in reasonable time (they ran ~40s for a=2+configs... actually the smoke test DID complete with the sieve — took under 5 min). The full run: a-sweep {2,4,6,8} + h-conv {0.01,0.005,0.0025} + lambdas {−0.5,−1,−2} + thetas {0,π/2,π} — many configs, each rebuilding Q (S(k) for N up to 3200) and solving 3200² bordered systems. a=8: S for 3200 k's; h=0.0025 at a=4: N=3200 too. Big cost: S(k) python loop ~3200 × ~2-5ms = 10s each, plus solves. Total maybe 20-30 min. Also the a=4 h=0.005 config is computed FOUR times (sweep, h-conv, λ=−1 in sensitivity, θ=0 in sensitivity) — wasteful. Optimize: 1. Cache configs (dict keyed by (a,h) → build once, reuse across λ/θ). 2. Speed up S: vectorize across k? The quad loop per k is the bottleneck. Could batch: precompute ρ on a fine grid? No — that was the noise issue. Alternative: batch GL nodes across all k into one g_float call per... the mpmath lerch for t ≤ 0.35 is per-point Python — batch those too (they're only for k ≤ 70/h·... few). 3. Reduce scope: drop a=8 (a ≤ 6 needs e^12 sieve — faster), or coarser: keep a ∈ {2,4,6} (T_MAXG=12, sieve 162k — fast), h-conv at a=4 with {0.01, 0.005} only, lambdas {−0.5,−2}, thetas {0,π/2,π}. Also sieve speed: vectorize? Use sympy primerange? The current sieve: Python loop over 2..N with is_comp check — for 8.9M that's ~10-20s, OK, but the prime-power while loops are fine. Actually simplest speedup: limit a to 6 → N = 162k → sieve < 1s. Also add S caching across configs: same (a,h) reused. Let me restructure: build_once(a,h) returns dict; zeros computed from it per (λ,θ). Reduce A_SWEEP to {2,4,6} plus maybe 8 if time permits... keep {2,4,6,8} but with caching the a=4/h=0.005 reuse saves ~3 builds. Estimate per config build: a=8: N=3200, S loop ~15s + toeplitz + solves 3200² (~20s × 3 λ + ...). Hmm solves: one Cholesky per (a,h,λ): 3 λ values × 4 a + h-conv 2 extra + ... ~ 14 solves of up to 3200² — ~3-4 min total. S builds: 6 configs ~ 1-2 min. Total ~ 6 min. OK with caching. Rewrite main with build cache.

Timed out — too slow. Optimizing: cache (a,h) builds across λ/θ variants, restrict sieve to e^14 (a ≤ 7), drop redundant rebuilds.

While that runs in the background, I can start drafting D-020 skeleton... better to wait for data. Meanwhile, let me think about the density paradox resolution and what analysis D-020 needs. Actually let me check on progress shortly via reading the output file when notified. Meanwhile I could also verify my lattice expectation analytically: for the FREE operator (g=0 ⇒ A_a = −λ... no). Skip. Wait — one thing worth doing while waiting: sanity-check the theoretical expectation for the lattice spacing renormalization. The measured spacing: a=2: 1.5782 vs π/2=1.5708 (ratio 1.00471); a=4: 0.78680 vs 0.78540 (ratio 1.00178). Ratio ≈ 1 + c/a²? 0.00471·4 = 0.0188; 0.00178·16 = 0.0285. Or 1 + c/a: 0.0094 vs 0.0071. Hmm. Or the offset: maybe zeros are π(j+κ)/a with κ: at a=2, z1 = 1.5781: π(1+κ)/2 = 1.5781 ⇒ κ = 0.00465; a=4: π(1+κ)/4 = 0.7868 ⇒ κ = 0.00712. Not constant. Whatever — data will tell. Let me just wait for the background job. Actually — the job may take a while; I'll poll once it's likely done. The tool says I'll be notified. Wait.

While E-010 runs, let me double-check one theoretical point for D-020: the expected free lattice spacing for a deficiency-(1,1) extension of i·d/dx on [−a,a].

Committed. Now proceed to fork 2: 3.2 continuation — prime-side Li coefficients (Bombieri–Lagarias exact formulas) to push past n=116. The Li coefficients: λ_n = Σ_ρ [1 − (1−1/ρ)^n]. Bombieri–Lagarias give an exact finite formula for λ_n in terms of primes + constants: λ_n = (n/2)(log...)... The known exact expression (Bombieri–Lagarias 1999): λ_n = −Σ_{k=1}^{n} ... Let me recall: λ_n = (n/2)(γ_E − log(4π)·...)? Known: λ_n = Σ_{j=1}^{n} (−1)^... Actually the Bombieri–Lagarias formula: λ_n = (1/2)(n·log(2π)·...)? Let me derive properly rather than misremember. ξ(s) = ½s(s−1)π^{−s/2}Γ(s/2)ζ(s). Li coefficients λ_n = Σ_ρ [1−(1−1/ρ)^n] = (1/(n−1)!) (d/ds)^n [s^{n−1} log ξ(s)]|_{s=1}... something like that. Bombieri–Lagarias: λ_n = (1/(n−1)!) d^n/ds^n [s^{n−1} log ξ(s)] at s=1. Expanding ξ into its factors gives λ_n = S_1(n) + S_2(n) + S_3(n): - from ½s(s−1): elementary: λ contribution: 1 − (1−1/1)^n + 1 − (1−1/0)^n?? careful — the poles at s=0,1 aren't zeros; the formula via log ξ derivative still works with ξ including the ½s(s−1) factor, and since ξ(s) = ξ(1−s) product over zeros... The standard result (BL Thm 2 / equivalent forms in the literature): λ_n = n·(log(2π)/2)·... The classical decomposition (e.g., as in Lagarias or Bombieri–Lagarias): λ_n = S_1(n) + S_2(n) + S_3(n) where S_1(n) = (n/2)(γ_E + log(4π)·...)? I don't trust memory. Better: compute λ_n via the derivative formula directly with mpmath: λ_n = (1/(n−1)!) (d/ds)^n [s^{n−1} log ξ(s)]_{s=1} — mpmath can do high-order derivatives via diffs, but n up to 10^5 — NO. Need the prime-side exact formula. The known exact formula (Bombieri–Lagarias 1999, "Complements to Li's criterion"): λ_n = −Σ_{j=1}^n binom(n,j)·(1/(j−1)!)·... hmm. Actually there's the well-known arithmetic formula: λ_n = (n/2)log(2π) − n + 1 − (γ_E/2)n·... no... Let me look it up: the standard statement (Li's criterion literature): λ_n = S_1(n) + S_2(n) + S_3(n) + S_4(n), with S_1(n) = (n/2)(γ_E − 1 − ... I should just derive it or fetch. Derivation sketch: define λ_n = Σ_ρ [1 − (1−1/ρ)^n]. Using (1−1/ρ)^n = e^{n log(1−1/ρ)}... The BL formula: λ_n = −Σ_{k=1}^{n} (n choose k) η_{k−1}·(−1)^... where η_k are the Laurent coefficients of log ξ... The η-series: log ξ(s) around s=1: coefficients η_m = (−1)^{m+1}/m! (d/ds)^{m+1}... Cleanest computable exact formula (from the literature, e.g., used in all Li numerics): λ_n = (n/2)(log 2π... OK let me just fetch it — Bombieri–Lagarias exact arithmetic formula for λ_n. It's: λ_n = 1 − (γ_E + log 4π)n/2·... nope. FETCH. Actually I recall now with more confidence — the formula (e.g., in Lagarias "Li coefficients for automorphic L-functions", Thm 2.1 for zeta): λ_n = S_1(n) + S_2(n) + S_3(n) S_1(n) = (n/2) log(2π) − ... no... FETCH from web. The MathOverflow link in Notes.txt (equivalent forms of RH) likely has the Li formula. Or Wikipedia "Li's criterion": λ_n = Σ_{j=1}^{n} (−1)^{j−1}... Wikipedia Li's criterion: λ_n = (1/(n−1)!) d^n/ds^n [s^{n−1} log ξ(s)]|_{s=1}. And the arithmetic formula: λ_n = (n/2)(γ_E − log(2√π)) + ... I'll fetch. Given time (evening), maybe do fork 2 as a scoped sub-stage: fetch formula, implement E-011 (λ_n prime-side to n=10^5), validate against E-008's zero-side values for n ≤ 116. Good plan.

Committed. Moving to **fork 2: prime-side Li coefficients** (3.2 continuation). The goal: Bombieri–Lagarias exact arithmetic formula for λ_n, pushing past the zero-side limit n=116. Let me get the exact formula.

acb_series HAS `zeta`! So I can build the series zeta(1+t) — Arb's acb_series zeta... which wraps acb_dirichlet? Let me test: create acb_series with value at point... python-flint acb_series: flint.acb_series([coeffs], prec=?). How to get zeta(1+t) series: maybe `flint.acb_series([1, 1], n).zeta()`? i.e., zeta of the series (1 + t) — series composition evaluating ζ at a series point with pole — Arb handles Laurent? acb_series.zeta() probably computes ζ(s₀ + t)-jet if s₀ is the constant coeff... risky with pole at 1+t's constant = 1. Test directly: does .zeta() on series with constant 1 work (Laurent with valuation −1)? Test now. If it works: ξ jet: xi_series = 0.5*(1+t)*(t)* π^{−(1+t)/2} * gamma((1+t)/2) * zeta(1+t) — the t·zeta(1+t) product — if zeta series has Laurent valuation −1, series arithmetic handles it. Then log ξ series → η_j coeffs → λ_n = Σ C(n,j) j η_j. All in ball arithmetic at precision ~ 0.31n + 60 digits. Then E-011: compute λ_n for n up to... start: n ≤ 2000 (match E-008), validate: vs E-008 zero-side (n ≤ 116), vs λ_1 exact, vs Arias de Reyna asymptotic (n/2)(log n − log(2π) + γ − 1)... note E-008 used (n/2)log n as leading; the refined asymptotic includes the constant: λ_n ~ (n/2)(log n − log(2π) + γ_E − 1)? The note says λₙ ~ (n/2)(log n − log(2π) + γ − 1). Verify with our data. Then push to n = 10^4 (and maybe 10^5 if fast). Precision: n·log10(2) + 50 digits; for n=10^4: 3060 digits. Arb jet of length n at that precision: cost? acb_series ops are polynomial multiplications (FFT) — n=10^4 length at 3000 digits: heavy but OK (~seconds-minutes). n=10^5: 30k digits × 10^5 length — maybe minutes-hours. Start with n_max = 10^4, and a single spot at n = 10^5 if feasible. Test the series zeta now.

`acb_series.zeta` exists. Testing whether it handles the Laurent series at s=1.

Series zeta at the pole gives NaN (not Laurent-capable through this wrapper). Workaround: compute the jet of ζ at s=1 via the ETA function or via ξ directly. Options: 1. Build ξ's jet at s=1 WITHOUT zeta series: ξ(1+t) = ½(1+t)·t·π^{−(1+t)/2}·Γ((1+t)/2)·ζ(1+t). The product t·ζ(1+t) is what we need — can't get from series zeta at the pole. 2. Compute ζ jet at s=2 (regular), then... no, need at 1. 3. Use the function equation? ξ(1+t) = ξ(−t) — symmetric; the jet at 1 of ξ: ξ(1+t) entire. Compute ξ at complex sample points and FFT? With Arb balls this is certified but needs care with precision. 4. Compute the jet of the Dirichlet eta η(s) = (1−2^{1−s})ζ(s) at s=1: η is entire; η(1+t) = Σ (−1)^k η^{(k)}(1)/k! t^k... but how to GET it via series? (1−2^{1−s}) has a zero at s=1 — so η series = [series of (1−2^{−t})] × [zeta series] — still needs zeta series at 1. Circular. 5. Compute zeta jet at s = 1 via acb.zeta(s, derivative=1)? The acb.zeta(s, a=None) — a is the Hurwitz parameter. No derivative option. Hmm — but maybe flint.acb.zeta accepts derivative flag? signature showed (s, a=None). No. 6. Stieltjes constants directly: arb C library has arb_dirichlet_stieltjes — wrapped? We saw arb has no 'stieltjes'. Check flint.arb dir again for 'stieltjes' — not there. acb has? Check. 7. mpmath route: mpmath.siegelz... mpmath has `stieltjes(n)`! Yes — mpmath.stieltjes(n) computes the n-th Stieltjes constant (using the zeta-function formula; for large n it's slow/limited — mpmath's stieltjes works up to n ~ few hundred? It's implemented via numerical integration/series; documented up to n ≤ 5000ish?). Check. 8. Implement the jet of log ξ via my OWN formula with polygamma + Stieltjes-free evaluation: Actually there's ANOTHER route — evaluate log ξ at N roots-of-unity points around s=1 using acb.zeta (point values, certified) and take the jet via FFT with rigorous error control. More machinery. 9. Simplest robust: high-precision finite-difference-free approach via mpmath: taylor(log∘xi, 1, n) — mpmath.taylor computes high-order derivatives numerically (uses step-size extrapolation — NOT rigorous, errors grow with n; but we validate against known values: λ_1 exact, E-008's zero-side λ_n for n ≤ 116, and Arias de Reyna asymptotic). For n up to a few thousand, mpmath taylor with dps ~ 0.3n+50 could work but taylor's error control is heuristic (it estimates error internally). Try mpmath.stieltjes first: check availability/speed for n ~ 100–1000.

Series-zeta can't take the pole. Probing mpmath's Stieltjes constants — with γ_m in hand, my exact Leibniz identity gives λ_n directly.

mpmath.stieltjes is fast (0.15s at k=500). Question: accuracy for large k? Stieltjes constants grow in magnitude and are hard to compute accurately for large k; mpmath's implementation (numerical integration) may lose accuracy for k > ~1000 at fixed dps. Test accuracy at k=500, 1000, 2000 against known values... Known: γ_1000 etc. — I don't remember exact values, but we can validate the END PRODUCT: λ_n vs E-008's certified zero-side values for n ≤ 116, λ_1 exact, and asymptotic trend. Also positivity. Also cross-validate mpmath stieltjes vs Arb? Arb's acb zeta has no stieltjes... Alternative validation: compute λ_n via a completely different route at sample n (e.g., zero-side with rigorous tail for small n — E-008 did exactly that to n=116). Precision plan: working dps ~ ceil(0.31·n_max) + 60. For n_max = 2000: ~680 dps. mpmath stieltjes at high dps for k up to 2000 — check accuracy: compare stieltjes(k) at dps 100 vs dps 200 for k=500,1000,2000 — agreement digits estimate error. Also need polygamma at 1/2: ψ^{(m)}(1/2) = (−1)^{m+1} m! (2^{m+1}−1) ζ(m+1) — for large m, ζ(m+1) → 1; mpmath handles. And log(tζ(1+t)) series recursion: tζ(1+t) = Σ_{m≥0} c_m t^m with c_0 = 1, c_m = (−1)^{m−1}γ_{m−1}/(m−1)! for m ≥ 1. log: η_j^ζ := [t^j] log Σ c_m t^m: standard recursion: L_j = (c_j − (1/j)Σ_{i=1}^{j−1} i L_i c_{j−i})·... for log S where S = Σc_m t^m, L = log S: j L_j = j c_j − Σ_{i=1}^{j−1} i L_i c_{j−i} ... (S'/S = L': Σ j L_j t^{j−1} = S'/S ⇒ jL_j = j c_j − Σ_{i=1}^{j−1} iL_i c_{j−i}? Derive: L'·S = S': (Σ_{j≥1} jL_j t^{j−1})(Σ c_m t^m) = Σ_{m≥1} m c_m t^{m−1}. Coefficient of t^{j−1}: Σ_{i=1}^{j} i L_i c_{j−i} = j c_j ⇒ jL_j = j c_j − Σ_{i=1}^{j−1} iL_i c_{j−i} ✔ (c_0 = 1). Then η_j = (−1)^{j+1}/j + L_j − (log π/2)[j==1] + (1/2^j)ψ^{(j−1)}(1/2)/j! and λ_n = Σ_{j=1}^n C(n,j)·j·η_j. Wait — check the log(s) part: log s at s=1+t: log(1+t) = Σ (−1)^{j+1}t^j/j ✔. The ½ factor: ξ = ½s(s−1)π^{−s/2}Γ(s/2)ζ(s): log ξ = −log 2 + log s + log(s−1) − (s/2)logπ + logΓ(s/2) + log ζ(s). log(s−1) + log ζ = log((s−1)ζ(s)) = log(tζ(1+t)) ✔. −(s/2)logπ contributes −(logπ)/2·t ⇒ −(logπ)/2 to j=1 coeff ✔. logΓ(s/2) = logΓ(1/2 + t/2): coefficients (1/j!)(1/2^j)ψ^{(j−1)}(1/2) ✔. Sanity check λ_1: η_1 = 1 + L_1 − (logπ)/2 + ½ψ(1/2); L_1 = c_1 = γ_0. ψ(1/2) = −γ_E − 2log 2. η_1 = 1 + γ_E − (logπ)/2 − γ_E/2 − log 2 = 1 + γ_E/2 − log 2 − (log π)/2 = 1 + γ_E/2 − ½log(4π) ✔ matches earlier. λ_1 = C(1,1)·1·η_1 = η_1 = 0.0230957... ✔. Validation plan for E-011: 1. λ_1 vs known 0.02309570896612103381 (30+ digits). 2. λ_n for n=2..116 vs E-008 zero-side values (within their tail bounds). 3. λ_n/(n/2 (log n − log(2π) + γ_E − 1)) trend → 1 (Arias de Reyna). 4. All λ_n > 0. 5. Self-consistency: recompute at 1.5× precision and compare (accuracy estimate). Scope: n_max = 2000 first (dps ~ 700), then extend: n = 10^4 needs dps ~ 3100 — mpmath stieltjes at k~10^4, dps 3100: cost? stieltjes(k) each ~0.15s at dps 50... at dps 3100 slower; and we need ALL k up to n. Let me measure scaling in the run. Also the λ_n summation: C(n,j) j η_j with cancellation — need the precision budget. Note: mpmath.stieltjes(k) for large k: known accuracy issues? mpmath docs say stieltjes uses ... it computes via the formula involving zeta derivatives... Let me just test empirically: compute at dps 100 vs 150 for k = 1000, 2000 and count agreeing digits. Also — IMPORTANT alternative check: E-008's zero-side λ_n for n ≤ 116 are CERTIFIED (tail bound < 5%). And the zero side to n=2000 computed from zeros has large tail bounds beyond 116 but still gives an approximate target (few-% accuracy up to n~300?). Fine. Plan E-011 script: - params: n_max = 2000, dps = 700 (initial), maybe extend flag --n-max. - compute stieltjes γ_0..γ_{n_max−1} (cache in CSV/JSON? per protocol, data cached — the run caches its own output CSV; also save intermediate stieltjes? not necessary). - compute L_j recursion at dps, η_j, λ_n. - self-consistency check: recompute every-10th λ at dps·1.4 and compare. - validations as above. - outputs CSV: n, lambda_n, lambda_n/(n/2 log n), ratio to refined asymptotic, plus E-008 comparison for n≤116. Runtime: stieltjes calls: n_max=2000 at dps 700 — each maybe 0.5-2s ⇒ 2000 × 1s = 33 min. Hmm, too slow. Check timing at dps 700 first. If slow, reduce n_max to 1000 or optimize (stieltjes in mpmath is O(?)-per-call; maybe batch? There's no batch API). Alternatively compute Stieltjes via Arb acb zeta jet at... hmm, Arb CAN compute ζ jet at s=1? The C library acb_dirichlet_zeta_jet(s, len, deflate=1) handles the pole via deflation (returns jet of (s−1)ζ). But python-flint doesn't wrap acb_dirichlet. Alternative: use acb_series at s₀ = 1 + ε?? no. Hmm — actually, wait: maybe I can get the ξ jet directly: acb_series has 'lgamma', 'gamma', 'zeta'... The zeta method failed at the pole. But what about evaluating zeta series at s = 2 + t (regular!) and then... no. Alternatively use mpmath for the whole thing but with a FASTER stieltjes: mpmath's stieltjes implementation: for n ≤ some limit uses precomputed? It's fast. Measure at dps 700.

mpmath has fast Stieltjes constants. Checking timing/accuracy at working precision (n=2000 needs ~700 dps).

Interesting — after first computation, subsequent calls are instant (caching! mpmath caches stieltjes computations — it computes a block and caches). And dps300 vs dps200 for γ_1000 agree exactly (rel diff 0) — the cached value may be shared... to truly test accuracy, need fresh process per dps. Let me test in separate processes: dps 200 vs 300 fresh, γ_1000, γ_2000.

Caching muddies the accuracy check — testing fresh processes at different precisions.

## SESSION 042 HEADLINES (review revision — see journal-042)
1. **Certificate RETRACTED + REPLACED (79c96f2)**: the user's top
   finding — Misguich–Voros (Voros 2020, Exp. Math. 29(4)) verifies a
   DEFORMED Keiper–Li sequence Λ_n (G. Misguich, private communication
   2017), not the ordinary λ_n, so the citation could not carry the
   finite splice. Verified against the paper's own text (arXiv
   1703.02844). Replacement: **Johansson 2015 § 4.2** (Numer. Algor.
   69:253–270, arXiv 1309.2877) — rigorous interval-arithmetic
   computation of the ORDINARY Keiper–Li coefficients λ_0…λ_{100000},
   all positive (λ_100000 certified to ~2900 digits). Lean perimeter
   `LiVerifiedUpTo` reduced (5·10⁵) → (10⁵) (the assembly's hfinite
   branch uses exactly n < 10⁵ — nothing else changes); rebuild GREEN
   (8775 jobs); audit re-run clean.
2. **Count caught by the user: EIGHT → SEVEN named hypotheses** (2
   computational: RHUpTo, LiVerifiedUpTo; 5 analytic: ZeroCountProp,
   ZeroCountProp2, ZeroCountGlobalProp, NoLowZeros, MZeroProp). Fixed
   in the paper (abstract/intro/App B + the verbatim signature),
   LiClosed docstrings, NGUYEN.md, R-004, this file.
3. **Theorem statement ↔ trust boundary aligned**: both Theorem
   environments now assume (i) RH verified to T₀ (Platt–Trudgian)
   (ii) λ_n > 0 for n ≤ 10⁵ (Step 5); Appendix B's new instantiation
   list maps each of the seven hypotheses to its cited

At dps 1200, stieltjes(k) is fast (sub-second; caching shared work). So n_max = 2000 at dps ~1200 is trivially cheap; even n=10^4 at dps 6200 might be OK (test later). Now — before writing E-011, verify my η_j/λ_n formula numerically at small scale: compute λ_n for n=1..20 at dps 100 with the Stieltjes split and compare against E-008's zero-side λ_n (certified). Quick inline test.

Fast. Prototyping the λ_n formula at dps 100 against E-008's certified zero-side values before writing E-011.

The PDF text extraction is mangled (math symbols displaced), but Theorem 2 is visible. Let me decode: Theorem 2. For n = 1,2,3,... we have Σ_ρ [1−(1−1/ρ)^n] = Σ_{j=1}^n (−1)^{j−1} C(n,j) · (1/(j−1)!) lim_{ε→0+} { Σ_{m ≤ 1/ε} Λ(m)(log m)^{j−1}/m − (1/j)(log 1/ε)^j } + [1 − (log 4π + γ)/2] n − Σ_{j=2}^n (−1)^{j−1} C(n,j) (1−2^{−j}) ζ(j). Reading the mangled text: "Σ_{j=1}^n (−1)^{j−1} C(n,j) 1/(j−1)! lim_{ε→0+} { Σ_{m≤1/ε} Λ(m)(log m)^{j−1}/m − (1/j)(log 1/ε)^j } + 1 − ((log 4π + γ)/2) n − Σ_{j=2}^n (−1)^{j−1} C(n,j) (1−2^{−j}) ζ(j)." Wait the "+1& (log 4 ?+#) n / 2" part: "+1 − (log 4π + γ)n/2" — is the "1" inside? "[1 − (log 4π + γ)/2] n"? From the λ_1 remark: Σ 1/ρ = 1 + γ/2 − ½log 4π = 0.0230957 ✔. For n=1, Thm 2 gives: j=1 term: (−1)^0 C(1,1) (1/0!) lim{Σ_{m≤1/ε} Λ(m)/m − log(1/ε)} + [1 − (log4π+γ)/2]·1 − 0 (j from 2 sum empty). lim{Σ_{m≤x} Λ(m)/m − log x} = −γ_E·... hmm: Σ_{m≤x} Λ(m)/m = log x − γ_E·... actually the known limit: Σ_{m≤x} Λ(m)/m = log x − γ_E + o(1)?? The classical: Σ_{n≤x} Λ(n)/n = log x − γ_E + o(1) — yes (this is a form of Mertens for Λ: constant is −γ_E... let me verify with the n=1 identity: λ_1 = (−γ_E)·(−1)? + 1 − (log4π+γ)/2: with the limit = −γ_E: λ_1 = −γ_E + 1 − (log 4π + γ)/2 = 1 − (log 4π)/2 − γ/2 − γ + γ/... compute: −γ + 1 − (log4π)/2 − γ/2 = 1 − (log 4π)/2 − 3γ/2 ✗ ≠ 0.0231. Try limit = −γ_E−... Let me just compute: need limit L such that L + 1 − (log4π+γ)/2 = 0.0230957: 1 − (log4π+γ)/2 = 1 − (2.531024+0.577216)/2 = 1 − 1.55412 = −0.55412. So L = 0.0230957 + 0.55412 = 0.577216 = γ_E ✔!! So lim{Σ_{m≤1/ε}Λ(m)/m − log(1/ε)} = +γ_E?? But classically Σ_{n≤x}Λ(n)/n = log x − γ + o(1)? Hmm — actually the classical result: Σ_{n≤x} Λ(n)/n = log x − γ_E + o(1)... let me check numerically: Σ_{n≤x}Λ(n)/n − log x → ? Known constant: −γ_E is wrong sign apparently; the Mertens theorem for Λ: Σ_{p≤x} (log p)/p = log x + B + o(1) with B ≈ −1.33258 (the prime log sum constant). Σ Λ(n)/n = Σ_{p^k} (log p)/p^k = Σ_p (log p)/p · (1 + 1/p + ...) = Σ_p log p/(p−1)·... Σ_{p≤x} (log p)/p = log x − 1.3325 + o(1); adding prime powers: Σ_p (log p)/(p(p−1)) ≈ 0.7553: so Σ_{n≤x}Λ(n)/n = log x − 1.3325 + 0.7553·... hmm = log x − 0.5772 + o(1)?? −1.33258 + 0.75536 = −0.57722 ≈ −γ_E ✔! So Σ_{n≤x}Λ(n)/n − log x → −γ_E. Then the limit in Thm 2 = −γ_E, and λ_1 = −γ_E + [1 − (log4π+γ)/2] = −0.577216 − 0.55412 = −1.131 ✗. Sign mismatch — so the constant term must be +[1 − (log4π−γ)/2]-ish or the limit is defined with +(1/j)(log 1/ε)^j... The mangled text: "4(m)(log m) j&1 / m &1/ j (log 1/=) j" — I read: Λ(m)(log m)^{j−1}/m − (1/j)(log 1/ε)^j. For j=1: Λ(m)/m − log(1/ε) → −γ_E. Then total: −γ_E + something = 0.0231 ⇒ something = 0.0231 + 0.5772 = 0.6003. What's "1 − (log4π+γ)/2"? = −0.5541 ✗. What gives 0.6003? 1 − (log4π − γ)/2 = 1 − (2.5310 − 0.5772)/2 = 1 − 0.9769 = 0.0231: then −0.5772 + 0.0231... no. Try: 1 + γ/2 − ½log(4π) = 0.0231 directly (the remark). So the constant term must BE 1 + γ/2 − ½log4π for n=1. From "+1 − (log 4π + γ)n/2"... if it's "+[1 + (γ − log 4π)/2]n" = 0.0231·n: for n=1: 0.0231 + (−γ_E from limit) = 0.0231+0.577... no: 0.0231 − 0.577 = −0.554 ✗. Hmm. If the limit term is −γ: −γ + [1 + (γ − log4π)/2]·... −0.577 + 0.023 = −0.554 ✗. If limit is +γ and constant is [1 − (γ + log4π)/2] = −0.554: 0.577 − 0.554 = 0.023 ✔✔!! So with limit = +γ_E... but classically it's −γ_E?! Let me recheck the classical constant: Σ_{n≤x} Λ(n)/n − log x → ? Weil/standard: Σ_{n≤x} Λ(n)/n = log x − γ + o(1)?? Hmm — actually I recall Σ Λ(n)/n = log x − γ + o(1) IS a known result... wait no. Let me be careful: Σ_{n≤x} Λ(n)/n: this is log x + C + o(1) with C = −γ: from −ζ′/ζ(s) ~ 1/(s−1) − γ·... the constant in Σ_{n≤x}Λ(n)/n = log x − γ + o(1)? But my numeric estimate said −0.5772 = −γ too (via −1.3326+0.7554). Hmm wait: −1.33258 + 0.75536 = −0.57722 → C = −γ_E. So the limit = −γ_E. Then for λ_1 to work out, the "+1 − (log4π+γ)n/2" must actually be "+1 + (γ − log 4π)n/2"? = 1 + (0.5772 − 2.5310)/2 = 0.0231: total = −0.5772 + 0.0231 = −0.554 ✗ STILL. Unless the j=1 limit term has a sign: maybe it's lim{Σ Λ(m)(log m)^{j−1}/m − (1/j)(log 1/ε)^j} with an overall (−1)^{j−1} outside ✔ (+1 for j=1). Hmm. OR the limit constant: maybe Σ_{m≤x}Λ(m)/m = log x − γ is WRONG and it's log x − γ_E... I computed −0.5772 = −γ ✔ so limit = −γ. We need total +0.0231. Options: limit sign flipped in formula: −lim = +γ: γ + [1 − (log4π+γ)/2] = 0.5772 − 0.5541 = 0.0231 ✔!! So the j=1 term enters with a MINUS relative to my reading, i.e., the formula might be: λ_n = Σ_{j=1}^n (−1)^{j−1} C(n,j) · [−(1/(j−1)!) lim{...}] + ...? For j=1: −(−γ) = +γ ✔ then constant [1−(log4π+γ)/2] = −0.554... 0.577 − 0.554 = 0.0231 ✔. Hmm but I can't trust my decoding of mangled extraction. The limit as written: "lim { Σ_{m≤1/ε} Λ(m)(log m)^{j−1}/m − (1/j)(log 1/ε)^j }" =: −η_{j−1}-ish. For j=2: lim{Σ Λ(m)log m/m − ½(log x)²} =: some constant η₁-related (negative? unknown). The cleanest resolution: decode more context around the theorem, and validate numerically — compute the formula for n=1..20 and compare with E-008. The signs will resolve themselves empirically. My reading candidate: λ_n = Σ_{j=1}^n (−1)^{j−1} C(n,j) · L_j/(j−1)! + [1 − (log 4π + γ)/2]·n − Σ_{j=2}^n (−1)^{j−1} C(n,j) (1−2^{−j}) ζ(j) with L_j = lim_{x→∞} { Σ_{m≤x} Λ(m)(log m)^{j−1}/m − (1/j)(log x)^j }, L_1 = −γ_E. Test n=1: L_1 + [1−(log4π+γ)/2] = −0.5772 − 0.5541 = −1.131 ✗. So a sign is off somewhere. Alternatives: L_j with opposite sign, or constant [1 + (γ−log4π)/2], or the (−1)^{j−1} attached differently. Rather than guess: let me read more of the extracted text around the theorem statement and proof — lines 560-680 likely contain the limit evaluations (3.6, 3.7...) which clarify signs. Read on.

The extraction is mangled but Theorem 2 is recoverable. Let me read the surrounding proof text to pin the signs exactly.

The ZETA sum explodes: at n=80 it's −1.19e7, at n=100 it's +1.86e12. The zeta sum −Σ_{j=2}^n (−1)^{j−1}C(n,j)(1−2^{−j})ζ(j) should be ~ n log n-scale. Its terms: (−1)^{j−1}C(n,j)(1−2^{−j})ζ(j) — C(100,50) = 1e29, so cancellation of 27 digits at n=100. At dps 300 this should STILL be exact to 270 digits... unless the cancellation is much more severe. The exact value of this sum: Σ_{j=2}^n (−1)^{j−1}C(n,j)(1−2^{−j})ζ(j) — hmm, is there a closed form? Σ_{j} C(n,j)(−1)^{j−1}(1−2^{−j})ζ(j): since (1−2^{−j})ζ(j) = Σ_{m≥0}(2m+1)^{−j} =: λ(j) (Dirichlet lambda). Σ_{j=2}^n C(n,j)(−1)^{j−1}λ(j) = Σ_{m≥0} Σ_j C(n,j)(−1)^{j−1}(2m+1)^{−j} = Σ_{m≥0} [1 − (1−1/(2m+1))^n − n/(2m+1)]·... Σ_{j=0}^n C(n,j)(−1)^{j}u^j = (1−u)^n: Σ_{j=2}^n C(n,j)(−1)^{j−1}u^j = −[(1−u)^n − 1 + nu] = 1 − nu − (1−u)^n. So zeta-sum = Σ_{m≥0} [1 − n/(2m+1) − (1−1/(2m+1))^n]·... with u = 1/(2m+1): = Σ_{m≥0} [1 − n/(2m+1) − ((2m)/(2m+1))^n]. For large m: (2m/(2m+1))^n = (1−1/(2m+1))^n ≈ e^{−n/(2m+1)} ≈ 1 − n/(2m+1) + n²/2(2m+1)² − ...: so term ≈ 1 − n/(2m+1) − [1 − n/(2m+1) + n²/(2(2m+1)²) + O(m^{-3})] = −n²/(2(2m+1)²) + O(n³/m³): Σ_m converges like Σ n²/m² ✔. Value ~ −n²/8·ζ(2)-ish — MILD (~ −n²·0.2: at n=100: ~ −2000). But computed zeta-sum = +1.86e12!! So the evaluation is catastrophically wrong — at dps 300?! Terms C(100,j)(1−2^{−j})ζ(j) for j~50: 1e29·~1: the TRUE sum ~ −2000: cancellation 32 digits. dps 300 handles 32 digits easily. So mpmath computed 1.86e12 — that means the sum is NOT actually cancelling — meaning the identity Σ = Σ_m[...] doesn't hold?? No wait — the identity is exact algebra (finite sum). Unless mpmath's zeta(j) for large j... ζ(j) → 1 + 2^{−j}: (1−2^{−j})ζ(j) = (1−2^{−j})(1+2^{−j}+...) = 1 + O(2^{−2j})·... ≈ 1 for large j. Then the sum ≈ −Σ(−1)^{j−1}C(n,j)·1 = −[(1−1)^n − 1 + n]·... Σ_{j=2}^n (−1)^{j−1}C(n,j) = −[(1−1)^n − C(n,0)(−1)^0 − C(n,1)(−1)^1]·... = −[0 − 1 + n] = 1 − n. Hmm so zeta-sum ≈ −(1−n) = n−1 plus corrections — SMALL. The numerical value 1.86e12 at dps 300 is IMPOSSIBLE for exact arithmetic... unless mpmath's zeta(j) for large j has a BUG or loses accuracy? ζ(100): mpmath computes... should be 1+2^{-100}. Or binomial as mpf and the alternating sum: hmm. Actually wait — let me reconsider: at dps 300, C(100,50) ≈ 1.0089e29 exactly (integer). The alternating sum of ~100 terms of size up to 1e29: mpmath at 300 digits: each term exact to 300 digits, sum error ~ 1e29·10^{-300} = 1e-271. Fine. So the computed 1.86e12 CANNOT be rounding. It must be that the TRUE sum is actually ~1.86e12?? But the analytic evaluation says ~n²/8·ζ(2)... Let me directly compute Σ_{m≥0}[1 − n/(2m+1) − (2m/(2m+1))^n] for n=100 numerically and compare. If it gives 1.86e12, my algebra was wrong; if −2000-ish, then mpmath's zeta(j) for large j is broken. Hmm wait — actually I think I see it: λ(j) = (1−2^{−j})ζ(j) = Σ_{m≥0} (2m+1)^{−j} ✔. Σ_{j=2}^n (−1)^{j−1}C(n,j)λ(j) = Σ_{m≥0}Σ_j (−1)^{j−1}C(n,j)(2m+1)^{−j}. Inner: Σ_{j=2}^n (−1)^{j−1}C(n,j)u^j = −Σ_{j=2}^n C(n,j)(−u)^j = −[(1−u)^n − 1 + nu] = 1 − nu − (1−u)^n ✔. With u = 1/(2m+1): 1 − n/(2m+1) − (2m/(2m+1))^n ✔. For m=0: 1 − n − 0 = 1−n. Fine. So the double sum = Σ_m [...] ~ convergent ~ −n²/16·... Let me just compute both sides numerically at n=100 in float64: terms and the m-sum. Actually hold on — maybe I mislabeled: is the last sum in Thm 2 "−Σ(−1)^{j−1}C(n,j)(1−2^{−j})ζ(j)" or with (1−2^{1−j}) or (2^j−1)ζ(j)...? From the proof text: "Σ(−1)^{j−1} C(n,j) (1/(j−1)!) Σ_m (j−1)!/(2m+1)^j" = Σ(−1)^{j−1}C(n,j)Σ_m(2m+1)^{−j} ✔ (1−2^{−j})ζ(j) ✔. And in the theorem it appears with MINUS sign ✔ (as transcribed). And the derivation line shows "=(log 2)n + Σ(−1)^{j−1}C(n,j)(1−2^{−j})ζ(j)" — PLUS in the derivation, and the boundary integral evaluation −∫[g_n(x)−nx]dx/(1−x²)... = (log 2)n + Σ... then the theorem has "+1 − (log4π+γ)n/2 − Σ(−1)^{j−1}C(n,j)(1−2^{−j})ζ(j)": so the derivation's "(log 2)n" combined with other constants into "1 − (log4π+γ)n/2" and the ζ-sum flipped sign to MINUS. OK. Let me just numerically test the m-sum vs j-sum at n=100.

The ζ-sum is exploding — but its exact m-sum form should be small. Testing both sides at n=100 to isolate.

The j-sum gives 1.86e12, the m-sum gives −272.39. They should be equal (exact algebra)! Unless... the identity Σ_{j=2}^n (−1)^{j−1}C(n,j)λ(j) = Σ_m [1 − n/(2m+1) − (1−u)^n] — wait: Σ_{j=2}^n(−1)^{j−1}C(n,j)u^j: let me recompute for n=2, u=1/3: direct: j=2: (−1)^1 C(2,2) u² = −u² = −1/9 = −0.111. Formula: 1 − 2u − (1−u)² = 1 − 2/3 − 4/9 = −1/9 ✔. So inner identity is right. λ(2) = 1.2337: Σ_m (2m+1)^{−2} = 1 + 1/9 + 1/25 + ... = π²/8 = 1.2337 ✔. So the double sum Σ_j(−1)^{j−1}C(n,j)λ(j) = Σ_m [1 − nu − (1−u)^n] = T = −272.39?? But direct j-sum gives +1.86e12. CONTRADICTION — so one of the two computations is wrong. The m-sum: terms for small m: m=0: 1 − 100·1 − 0 = −99. m=1: 1 − 100/3 − (2/3)^100 = −32.33. m=2: 1 − 20 − (4/5)^100 ≈ −19. m=3: 1 − 100/7 − (6/7)^100 ≈ −13.3+... sum of first few: −99−32.33−19−13.3−10.1... Σ over m of ~−n/(2m+1) for m up to ~n/2: ~ −50·(harmonic-ish)... then tail ~ −n²/(2(2m+1)²) summable. Total −272 plausible. So T = −272.39. The j-sum: 1.86e12 must be a COMPUTATION issue: at dps 100, terms C(100,j)·λ(j): λ(j) → 1: the alternating sum Σ(−1)^{j−1}C(n,j)λ(j) — exact value −272: the terms reach 1e29 — cancellation of 29+2 = 31 digits — dps 100 leaves ~69 digits — SHOULD be fine!! Getting 1.86e12 (not a small error but a completely different value) means... mpmath's zeta(j) for large j? At j=100: ζ(100) = 1 + 2^{-100} + ... = 1 + 7.9e-31: at dps 100 fine. λ(100) = 1.0 printed ✔. Hmm so terms are right... Wait — maybe the issue: (1−2^{−j})ζ(j) for j=2..100 — the TRUE sum S = −Σ(−1)^{j−1}C λ(j) = −T? The relation between S and T: S = −Σ_j(−1)^{j−1}C λ(j) = −T ⇒ S = +272.39. But computed S_j = 1.86e12. So the j-sum evaluation is wrong by mpmath?? Let me compute the j-sum in EXACT rational arithmetic... λ(j) isn't rational. But split: λ(j) = 1 + (λ(j)−1): Σ(−1)^{j−1}C(n,j)·1 = 1−n... wait Σ_{j=2}^n (−1)^{j−1}C(n,j) = −[(1−1)^n −1 +n] = 1−n. So S_j = −[(1−n) + Σ(−1)^{j−1}C(n,j)(λ(j)−1)] = n−1 − Σ(−1)^{j−1}C(n,j)(λ(j)−1). The correction sum: λ(j)−1 = (1−2^{−j})ζ(j) − 1 = 3^{−j} + 5^{−j} + ... − 2^{−j}ζ(j)·... small for large j. The total should be ~272. For mpmath to give 1.86e12, the correction sum must be miscomputed: Σ(−1)^{j−1}C(n,j)(λ(j)−1): terms C(100,j)(λ(j)−1): λ(j)−1 ~ 3^{−j}: at j=50: C(100,50)·3^{−50} = 1e29·1.4e-24 = 1.4e5; alternating... the TRUE correction is small but the terms are ~1e5 with cancellation to ~170: 3 digits. Fine at dps 100. Hmm, so why 1.86e12?? Let me suspect mp.zeta(j) for integer j — maybe at dps 100, mpmath's zeta integer evaluation has an issue for large j?? ζ(100) = 1+2^-100+...: printed λ(100) = 1.0 ✔ looks right. OR mp.binomial issue? No. Let me directly debug: compute the partial j-sum term by term and find where it diverges from expectation. Actually simpler test: compute S_j at dps 100 vs dps 300 vs dps 1000 — if the answer changes with dps, it's a conditioning issue (maybe I'm wrong about the cancellation magnitude). The corrections: let me bound the true cancellation: S = −T = 272.39. Individual terms |C(100,j)λ(j)| up to C(100,50)·1 = 1.0e29. So cancellation is 1e29 → 272: 27 digits. dps 100 → fine. UNLESS the alternating sum passes through intermediate partial sums much larger... no, error is determined by max term size, not partial sums. So mpmath at dps 100 giving 1.86e12 is flat-out bizarre UNLESS mp.zeta(j) is inaccurate for some j: e.g., ζ(j) for j ~ 70-100: mpmath uses... for large integer arguments, mpmath's zeta might have a subtle bug or need higher precision: ζ(90) = 1 + 2^-90 + 3^-90...: 2^-90 = 8e-28 — representable at dps 100 ✔. Hold on — let me recheck: maybe I mis-derived and the sum really IS 1.86e12, and T is miscomputed. T: Σ_m[1 − n u − (1−u)^n], u = 1/(2m+1): for m=0: u=1: 1 − 100 − 0 = −99 ✔. Sum to m=2e6 with early break — the tail beyond break: term ~ −n²/(2(2m+1)²): at m=2e6: −1e4/(2·1.6e13) ~ −3e-10: tail Σ_{m>M} ~ −n²/(8M) ~ −1e4/1.6e7 = −6e-4. Hmm the break condition |term| < 1e-90 never triggers (term ~ 3e-10 at 2e6)! So the loop ran all 2e6 — fine, T ≈ −272.386 with tail −6e-4 — accurate ✔. So we have a genuine contradiction between two exact-evaluation routes of the same quantity — meaning one route has a computational bug. Let me test with n=30 (small) where cancellation is 2^30 ~ 1e9 — 9 digits: dps 100 trivially handles: compare.

Direct contradiction between two exact forms of the same sum — hunting the bug at small n first.

At n=10..50 the two agree (small differences from the m-sum truncation tail ~ −n²/(8M): at M=2e5, n=50: −2500/1.6e6 = −1.6e-3 ✔ explains the gaps). So the algebra is right, and S_j is computed correctly at n ≤ 50. At n=100, S_j = 1.86e12 — let me recompute S_j at n=100 at dps 100 vs 300 vs 1000. If it changes → conditioning worse than I estimated (maybe the max term isn't the issue but mpmath zeta at large j loses digits? or...). Actually — think again about the TRUE cancellation: the sum value −272 vs terms up to C(100,50)·λ(50) = 1.0089e29 — but wait, are there really such large terms? λ(j) ≈ 1 for all j≥2. So terms are ~C(100,j): up to 1e29 ✔. The alternating binomial sum Σ(−1)^{j−1}C(100,j) = 1−n = −99 — cancellation of 27 digits IN THE MAIN PART. dps 100 gives 73 correct digits after cancellation — should be exact!! Unless mpmath's mp.zeta(j) for large j returns something like 1 + garbage at the 1e-30 level — then C(100,j)·garbage ~ 1e29·1e-30 = 0.1 — small. Hmm. Actually — WAIT. mp.mpf(2)**(-j): for j=100, 2^-100 fine. mp.binomial exact. Let me just recompute n=100 S_j at multiple precisions.

Small n agrees — so the algebra is right. Testing n=100 across precisions.

Only the old output file exists; the new background task's output file isn't there yet (or the task ID directory differs). The task bfv9yy7id was said to write to that path. It may not have flushed yet. Wait for the completion notification. Meanwhile, let me quickly sanity-check ζ(1.5) — I claimed it's wrong; double-check with flint to be sure the bug claim is right (already done for ζ(0.5), ζ(3) — solid). Just wait for the notification.

The output file hasn't appeared yet — the job is still running. Waiting for completion.

Exit code 143 = killed by timeout (600s default I set — I passed timeout 600000 = 10 min). The O(n²) mpmath loops at dps 1000 are too slow: lambda sums 2e6 iterations with mp.binomial at dps 1000 — binomial(2000,1000) is a 600-digit integer; mpmath binomial computes via factorials each time — expensive. Let me optimize: 1. Precompute binomials row by row? Each λ_n needs row n of Pascal — iterative update: C(n,j) from C(n,j−1)·(n−j+1)/j — exact integer via Python ints (arbitrary precision) — fast. Use plain Python ints for binomials (not mp.binomial). 2. The eta-sum and zeta-sum can share the binomial recurrence. 3. η/ζ terms as mpf; multiply int×mpf. 4. Reduce self-consistency recompute: it currently re-does stieltjes+eta at 1.4× dps for ALL k — that's the expensive part. Only need eta2/ζ2 for j ≤ sample n values... but sample includes n_max — full recompute anyway. Alternative: self-consistency via a SECOND run at n_max with different dps only for the final sums — reuse? simpler: keep but it's ~2× cost. Reduce sample to {1, 2, n_max//10, n_max//2} — drop n_max? No — n_max is the important one. Keep but optimize. Estimated costs: the recursion E[k] O(n²) mpf muls at 1000 dps: 2e6 muls — mpmath mpf mul ~ 5µs → 10s ✔. The lambda sums: 2e6 iterations with Python-int binomial recurrence + int×mpf mul: ~10-20s ✔. stieltjes: measured fast. So the main cost was probably mp.binomial (factorial of huge ints per call: C(2000,j) via factorial(2000) — 2000 calls × ... actually per (n,j) pair! factorial(n) recomputed per pair — 2e6 factorials of up to 2000! — that's the killer. Fix with recurrence. Also the self-consistency block doubles everything AND recomputes stieltjes at 1.4 dps — the stieltjes caching should make the second pass cheaper. Let me rewrite the lambda computation with int binomial recurrence, and restructure for speed. Also consider computing λ_n incrementally... just do per-n loops with recurrence. Also, exit 143 killed at 600s — output showed nothing? The output file should have the early prints. Check it.

Timed out at 10 min — `mp.binomial` per (n,j) pair (2e6 huge factorials) is the bottleneck. Checking partial output, then optimizing with integer Pascal recurrence.

Timed out again — and only the FIRST line printed. So the stieltjes sweep itself never finished in 10 min at dps 1000! Earlier micro-test: stieltjes(2000) at dps 1200 took 0.6s — but that was following earlier calls (500, 1000) in the same process. Hmm — but here we call stieltjes(k) for ALL k = 0..2000 sequentially. Maybe the cost is per-k with no sharing: 2000 × 0.3s = 600s ✔ matches the timeout! mpmath's stieltjes caches per-(n, prec) but not across n. Fix options: 1. Check how mpmath computes stieltjes: mpmath.stieltjes(n) — uses... in mpmath/libmp or functions/zeta.py: stieltjes computed via numerical differentiation of (ζ(s) − 1/(s−1)) at s=1? or via the formula with zeta derivatives. Each call O(something). Not shareable. 2. Use Arb instead: Arb's C library has acb_dirichlet_stieltjes (fast, rigorous) — but python-flint doesn't wrap it. Check python-flint 0.9: maybe flint.acb_dirichlet? No. Hmm — check `flint.arb` for 'stieltjes' again — earlier probe: arb methods printed only filtered ones; let me search 'stieltjes' across all of flint. 3. Write our own Stieltjes computation: γ_m via the contour/integration formula or via the log ξ jet... circular. 4. Reduce n_max to 1000 or 500 for this pass (stieltjes 0..500 ~ 150s? at dps 700...). Actually measure: time stieltjes sweep to 500 at dps 500 in-process. Check flint for stieltjes wrapper first.

Timed out again — the per-k `mpmath.stieltjes` calls don't share work (2000 × ~0.3s). Checking if python-flint exposes Arb's native Stieltjes.

`flint.acb.stieltjes` EXISTS (my earlier filter missed it — I only grepped arb's list for 'stiel'|'zeta'|... and it showed digamma/gamma/... — no wait, the earlier probe printed arb's methods; acb's list was filtered for zeta|gamma|psi|log and didn't include stieltjes because I didn't search for it). flint.acb.stieltjes exists!

Stieltjes sweep worked (68s), eta recursion fine. Failure: flint.arb(j).zeta().mid().str() includes the brackets "[...]"... The .str() of an arb mid might include radius bracket format "[1.6449... +/- ...]". Use .str(radius=False)? For arb: `arb.str(n, radius=False)` — but mid() returns arb? mid() of arb returns... In python-flint, arb.mid() returns arb? The string started with "[1.6449...787" — bracket included. Fix: use `.str(n, radius=False)` on the arb directly, or better `flint.arb(j).zeta().mid()` then convert via str(). Fix: def arb_to_mpf(x): return mp.mpf(x.mid().str(radius=False) if hasattr...) python-flint arb.str(digits, radius=False) gives plain decimal. Let me check API: arb.str(n=..., radius=False)? In python-flint: `arb.str(self, n=0, radius=True, condense=None)`. So: flint.arb(j).zeta().str(0, radius=False) — with n=0 meaning full digits. Hmm n=0 → maybe default. Use .mid() then .str()? mid() returns an arb with zero radius; .str(radius=False) works on arb. Simplest: mp.mpf(flint.arb(j).zeta().mid().str(radius=False)). Hmm but if mid() is arb, str(radius=False) ok. Or use float string with enough digits: .str(dps+10, radius=False).

Stieltjes sweep worked (68s). The Arb→mpmath string conversion picked up the bracket format. Fixing.

Wait — flint says ζ(2) = 1.644934066848226436472415166646025189219, but π²/6 = 1.644934066848226436472415166646025189218949... ✔ correct. ζ(3) correct ✔. Note interesting: mpmath's broken ζ(2) was 1.64493406684822640606569166266 — differs at digit 18. Confirms the bug. Rerun E-011.

Results: λ_1 err 1.98e-16 (should be < 1e-28 — but 2e-16 is just precision-cancellation level at... wait dps 1000, λ_1 involves tiny cancellation — err 2e-16 means something's off — λ_1 = 1 − η_0 − c2 = 1 + 0.5772156649 − 1.5541... should be computable to full precision; err 2e-16 suggests c2 or η_0 only accurate to 1e-16?! η_0 = E[1] from the recursion... E[1] = N_[1] = −(−1)^1 γ_1/0!·... wait N_[1] = −(−1)^1 γ_1/0! = γ_1?? Hmm no: N_[m+1] = −(−1)^m γ_m/(m−1)! for m ≥ 1: m=1: N_[2] = +γ_1. N_[1] stays 0. D_[1] = γ_0. E[0] = N_[0] = 1. E[1] = N_[1] − D_[1]E[0] = −γ_0. eta[0] = E[1] = −γ_0 ✔ = −0.577215664902 ✔ printed. λ_1 = 1 − C(1,1)η_0 − c2·1 = 1 + 0.5772156649 − 1.5541199559 = 0.0230957090. Error 2e-16 — at dps 1000?? The subtraction 1 + 0.5772 − 1.5541 has NO cancellation issue. So either gam[0] or c2 (log(4π), euler) is only accurate to 1e-16. mp.euler, mp.log accurate. gam[0] = mp.mpf(str(stieltjes(0)))... stieltjes(0) = γ_E ✔. Hmm — the parallel sweep returns STRINGS; mp.mpf(string) at dps... the strings from workers at dps=1000: fine. Wait — maybe stieltjes(0) in the worker used mp.stieltjes(0) — correct. Hmm, err 2e-16: let me compute directly: 1 + γ − (log4π+γ)/2 = 1 + γ/2 − log(4π)/2. The known λ_1 = 0.02309570896612103381...: if our value differs at 2e-16, one of the pieces is off at 1e-16 — mp.log(4·mp.pi)? mp.pi accurate. mp.euler accurate. stieltjes(0) = euler ✔. OH WAIT — the V1 check compares lam[1] computed in the FULL pipeline (dps 1000) vs known. Hmm 2e-16... Actually let me test the pieces directly. But MORE IMPORTANTLY: λ_2000 = 8.6e584 — EXPLODED. V5 self-consistency says rel dev 0.0 (consistent at 1.4× dps!). So the computation is self-consistent but WRONG — meaning a FORMULA/structural issue that only blows up at large n, OR the Stieltjes constants at high k are wrong in a precision-independent way (mpmath stieltjes broken for large k?!). γ_1000 ≈ −1.57e486 — matched across dps 200/400 earlier (30 digits). Hmm but that was γ_1000 at low dps. The explosion scale: 8.6e584 at n=2000. Which part? Let me decompose at large n. The zeta-sum: terms C(2000,j)λ(j): the exact value ~ −n²/16-ish... at n=2000: ~ −2.5e5. Cancellation 2^2000 ~ 10^602 — at dps 1000: residual error ~ 10^{602−1000}·... = 10^{−398} — tiny. But wait — the TRUE zeta sum value: is it ~ n²? From the m-sum: Σ_m[1 − nu − (1−u)^n] ~ −n²/16·ζ(2)-ish ~ −n²·0.1 — at n=2000: −4e5. And λ_2000 true ~ (n/2)log n ~ 7600. We got 8.6e584 — that's 2^2000-scale·10^{−16} = 10^{602}·10^{−18}: consistent with zeta[j] errors ~1e-16 relative!!! flint.arb(j).zeta().str(mp.dps + 10, radius=False): the string at mp.dps+10 digits — but flint.ctx.prec = 3530 bits ≈ 1063 digits ✔. But wait — .str(n) rounds to n digits — mp.dps+10 = 1010 digits ✔. Hmm — but j can be up to 2000; ζ(2000) = 1 + 2^{−2000}: at 1010 digits, ζ(2000) rounds to exactly 1.000...0 (2^{−2000} = 10^{−602} needs 602 digits ✔ captured). ✔ fine. But the ZETA-SUM error: λ(j) = (1−2^{−j})ζ(j): we compute w[j] = (1−mpf(2)^(−j))·zeta[j]: 2^{−j} exact; fine. Sum error: Σ C(n,j)·δw[j]: δw ~ 1e-1010·|w| ~ 1e-1010: ΣC ~ 2^2000 ~ 10^{602}: error ~ 10^{−408} tiny. So zeta-sum is fine. ETA-sum then: terms C(2000,j)η_{j−1}: η_k ~ 3^{−k}: max term at j ≈ n/4: C(2000,500)3^{−500} ~ 10^{495}·10^{−239} = 10^{256}: error budget fine. BUT: the η values themselves from the series recursion — the recursion E[k] = N_k − Σ D_i E_{k−i}: catastrophic error amplification possible in series division at high order! The recursion is known to be unstable when D has small coefficients... D(u) = uζ(1+u) = 1 + γ_0 u − γ_1 u² + ...: D has a ZERO at u = ρ−1 (|u|≈14) and at u = −3 (trivial): the series 1/D has radius 3; computing E_k via the recursion in exact arithmetic is fine; in finite precision: errors amplify by ~3^k/14^k?? The recursion error grows like (1/3)^k·... error amplification ~ (radius)^{−k} = 3^k·10^{−dps}: at k=2000: 3^2000 = 10^{954}: need dps > 954 + target. dps = 1000: leaves ~10^{−46} absolute error in η_2000 — then C(2000,j)η: error ~ 10^{256}·10^{−46}·(relative-to-3^{−j} scaling)... hmm — actually the error in η_k ~ 3^k·10^{−1000}·(input scale). Input coefficients D_i ~ γ_{i−1}/(i−1)! — TINY for large i (10^{−2000}-ish at i=1000). The recursion combines terms of wildly different scales: at step k, E[k] = N_k − Σ D_i E_{k−i}: D_i for small i ~ O(1), E_{k−i} ~ 3^{−(k−i)}: products ~ 3^{−k+i} — the dominant error source: absolute errors of E[j] for small j (~10^{−1000}) get multiplied by D_{k−j}... D_{k−j} for large k−j is TINY (10^{−2000}·...). Hmm — actually the recursion is stable-ish in absolute terms? E[k] absolute error ~ Σ_i |D_i|·err(E_{k−i}) + err(N_k): errors add with |D_i| ≤ O(1) for small i: err(E[k]) ≤ Σ_{i small} |D_i| err(E[k−i]) + 10^{−1000}·scale(N_k): grows linearly in k: err(E[k]) ~ k·10^{−1000}·max|D|-weighted. Not 3^k amplification (since |D_i| for i≥1 are < 1: D_1 = γ_0 = 0.577, D_2 = −γ_1 = 0.0728...: Σ|D_i| < 1?? 0.577 + 0.0728 + ... < 1 likely ✔ then error stays bounded ~ k·10^{−1000}·small — fine). Hmm so where does 8.6e584 come from?? Let me decompose the parts at n=2000 (eta-sum, const, zeta-sum) directly. And also test intermediate: λ_n for n = 100, 500, 1000, 1500 from the CSV.

Self-consistent but wrong at large n — something structurally off. Decomposing the three parts across n.

Two facts: 1. λ_1 pieces give 0.0230957089661210**09098** vs known ...**03381**: differs at 2.5e-18!! But η_0 and γ_E agree exactly, and c2... The difference must be in mp.log(4π) or... 1 + γ_E − c2: if all inputs exact, error should be ~1e-1000. Getting 2.5e-18 means mp.log(4·mp.pi) or mp.euler is wrong at 1e-18?!? OR — wait, maybe it's mp.pi! If mp.pi is computed wrong at 1e-18 in this environment... mpmath mp.pi is computed on the fly. Let me check mp.pi, mp.euler, mp.log against known values. Actually — from the CSV: λ_50 = 43.5288 (vs E-008's 43.19±1.3 ✔ fine!), λ_60 = 46.00000006 — vs expected λ_60 ~ (60/2)(log 60 − log 2π + γ − 1) = 30·(4.094 − 1.838 + 0.577 − 1) = 30·1.833 = 55?? Hmm λ_60 = 46.0000000596 — suspiciously close to an integer! And λ_70 = −18039 (explosion started). And E-011's CSV λ_50 = 43.52880859375 = 43 + 0.52880859375 — .52880859375 = 0.52880859375 exactly — that's 0.5288... = 543/1024-ish? 0.52880859375 × 2^20 = 554435.5... hmm these look like DOUBLE-precision artifacts!! 46.00000005960464477539063: 0.00000005960464477539063 = 6.25e-8 = 2^-24 — FLOAT32-style artifact?? Or the η values coming back from the worker processes are... STRINGS at dps 1000 ✔. Hmm. λ_50 = 43.52880859375: 0.52880859375 = 0.52880859375: ×2^10 = 541.5... ×2^20 = 554435.5 hmm not clean. Whatever. KEY: λ_1 error 2.5e-18 — some CONSTANT is wrong at 1e-18. Test mp.pi, mp.log, mp.euler against known digits.

λ₁ differs at 2.5e-18 even with exact inputs — a core constant is off. Testing mp.pi/log/euler against known digits.

MASSIVE finding: **mp.pi is WRONG**: 3.141592653589793**11599796346854418516159057617** vs known 3.141592653589793**2384626433832795028841971693993751** — wrong from digit 16! And mp.euler wrong from digit 17; mp.log(2) wrong from digit 16. The ENTIRE mpmath high-precision arithmetic in this venv is broken at ~16 digits?!? But then how did E-009a validations pass with 25-digit agreement (g_mp vs eq 2.2, exact matches to 25 digits)?! And stieltjes matched 30 digits across dps! And the explicit formula test closed at 8.9e-16?! Wait — maybe it's not "wrong digits" but a PRINTING/conversion issue: mp.nstr conversion? Or mpmath's mpf arithmetic uses Python floats somewhere... Hmm — but E-009a printed mp.nstr values that matched: e.g., c2 = −0.875059975404 (12 digits — only 12 digits shown). The exact-zero tests: A1 err 0.0 — consistent computations both sides (same broken pi in both? polygamma vs lerchphi both wrong the same way? unlikely to cancel...). Hold on — Python 3.14 changed float REPR? No... Wait, actually: could it be that mp.dps assignment isn't taking effect and computations run at... no: values differ from double precision too. Actually — hmm: 3.14159265358979311599796... — the correct double π is 3.141592653589793 (16 digits): the shown value matches π to 15 digits then garbage. So mpmath is computing π to only ~double precision then padding with garbage — as if its "prec" is being misread: maybe Python 3.14 changed something in mpmath's bit-counting (e.g., int.bit_length? no...). OR the venv has a broken libmp C backend... mpmath is pure python but has optional gmpy2 backend! If gmpy2 is installed and BROKEN (built for different Python), mpmath uses gmpy2's mpz... gmpy2 version mismatch could corrupt high-precision arithmetic!! Check: import gmpy2; mpmath uses gmpy2 if available (mpmath.libmp.BACKEND). Check backend and gmpy2 presence.

**mp.pi itself is wrong from digit 16** — the entire mpmath high-precision layer is suspect. Prime suspect: a broken `gmpy2` backend. Checking.

Even 1/7 is wrong at digit 16!! 0.1428571428571428**4921**... — so basic mpf DIVISION is broken beyond double precision. This is a fundamental mpmath-on-Python-3.14 breakage: likely `int.to_bytes`/`math.frexp`/`float` conversions... Actually: the values are correct to ~double precision then garbage — hallmark of mpmath falling back to float arithmetic somewhere, OR libmp's normalization loops broken by a Python 3.14 change. Possibly `int.__index__`/`operator.index` behavior, or the `math` module's ldexp... whatever. CRITICAL QUESTION: which past results are affected? - E-001 (window constants, 60-digit): used sympy + mpmath — sympy is INDEPENDENT (its own mpmath-free backend? sympy uses mpmath for evalf!! sympy 1.14 evalf calls mpmath...). E-001 "both PASS" at 60-digit — if mpmath broken, how did it pass? Maybe E-001's comparisons were against values computed with the SAME broken mpmath (both sides) — self-consistent but wrong at digit 16+? But E-001 compared against HAND-derived R(ψ_MT) = 1.32749930 — 8 digits only — can't see the bug. - E-002 zeros: zetazero — the values matched known zeros to... I verified 14.1347251417346946311681676889 — is that the KNOWN value? Known first zero: 14.1347251417346937904572519835624... — mpmath gave 14.134725141734694**6311681676889** vs known 14.134725141734693**7904572519835** — DIFFERENT from digit 16!!! So even E-002's zeros are wrong beyond 16 digits! But λ_1 from E-008 matched literature to... λ_1 known 0.023095708966121: E-008's zero-side λ_1 = 0.02296 — within its tail bound 5.4e-4 — only 3-digit agreement — never tested digit 17! So: ALL mpmath-based results in this venv are only reliable to ~15 digits. Everything done at dps 25-60 claiming 20+ digit accuracy is actually ~15-digit accurate. The qualitative results (checks passing within tolerances like 1e-9) — mostly still valid since tolerances ≫ 1e-15... but the E-009a "25-digit validations" are only ~15-digit trustworthy — still fine for their purpose (validating formulas to 1e-15 vs tolerances used). The root cause must be identified: is it ALL mpf ops? 1/7 wrong at digit 16 — division broken. Actually wait — maybe it's the STRING conversion (nstr) that's broken, not the arithmetic! 1/7 stored correctly but printed wrong? Test: mp.mpf(1)/7 == mp.mpf('0.142857142857142857142857142857...')? Compare internally: (1/7 - from_string) and print the difference... if printing is the broken step, the difference would be 0.

Even 1/7 is wrong at digit 16 — but maybe it's the *printing* that's broken, not the arithmetic. Testing internally.

can you check to see how many python process is running in the background. I see too many and i dont know it's from you?
