This is a Lean formalization file — clearly not malware, it's the project's own research code. Continuing. Now I understand the current state of LiSkeleton.lean: - `liCoeff` defined as zero-side tsum - `RHUpTo`, `LiVerifiedUpTo` hypotheses - `lambda_pos_finite_height` — the sorry'd tier (ii) target - Tier (i) proved: `sInfty_lower_bound`, `marginTilde_convex`, `chain_rule_sqrt_shift` - `marginTilde F` takes an abstract majorant F with hypothesis `hmaj : ∀ T, (Ncount 0 T : ℝ) ≤ F T` and `hψ` (block table) Now for the assembly-first plan (session-012-notes): 1. State `lambda_pos_finite_height` with the finite-part bound as an explicit named hypothesis `SfBound : ∀ n, |S_f n| ≤ B n`, discharge the full assembly conditional on it. 2. Then triage what's inside SfBound. I need to read D-037 to understand the exact assembly chain: how λ_n positivity follows from S_∞ lower bound + S_f bound + margin argument. Key mathematical content: The Lagarias decomposition: λ_n = S_∞(n) + S_f(n) roughly (arithmetic side). Actually λ_n = S_∞(n) − S_f(n) or similar — I need the exact signs. From E-021: "Exact S_∞(n) computation... measure true |S_f(n)| curve vs the traced bound". The margin is margin(n) = S(n) − B(n) + 1 where S(n) is the S_∞ lower bound and B(n) is the bound on |S_f(n)|... and margin convex + margin(N₀) > 0 + margin'(N₀) > 0 ⟹ margin > 0 on [N₀, N₁]. Then finite verification covers n ≤ N₀ (with N₀ = 80000 < 5×10⁵ Misguich–Voros bound). Wait, actually E-028: N₀ = 80 000, overlap 6.25×. So the assembly: - For n ≤ N₀ = 80000: covered by LiVerifiedUpTo (5×10⁵ ≥ 80000). ✓ - For N₀ ≤ n ≤ N₁ = (T₀−1)²: - λ_n ≥ S_∞(n) − |S_f(n)| ≥ S_∞(n) − B(n) (where the bridge λ_n = S_∞(n) − S_f(n)... something) - S_∞(n) ≥ S(n) (the archimedean lower bound, proved in Lean as sInfty_lower_bound) - margin(n) = S(n) − B(n) + 1 > 0 by convexity + base point - The bridge: Lagarias Thm 6.1 connects λ_n to the zeros below T₀ = √(n)+1... The finite-height bridge: for n ≤ (T₀−1)², all zeros with |Im ρ| ≤ √n+1 are on the line (by RHUpTo T₀), which is used in bounding... hmm, actually I need to read D-037 to get this right. Key: what exactly is B(n) and what's the exact algebraic relationship? Let me read D-037 and the relevant parts of D-056/D-057. Also need to check Zeta23.Statement for Ncount, IsNontrivialZero, zeroMult definitions. Let me read D-037 first.
This is the project's own Lean research code (RH formalization), not malware — continuing with the task. The skeleton is clear: tier (i) machinery is in place, and `marginTilde F` already takes the zero-count majorant as an abstract parameter with `hmaj`/`hψ` hypotheses. Now I need the exact D-037 assembly chain to design `SfBound`.
