The user wants a full audit of the NguyenRH1 Lean package before submission. This means: 1. **Full clean build** of the package (`lake build NguyenRH1`) — all modules: LiSkeleton, LiBasePoints, SuzukiSkeleton, ValleySkeleton. 2. **Full PrintAxioms audit** — every declaration; verify only the 3 standard axioms everywhere, and sorryAx ONLY on the 5 intended skeleton statements (1 Suzuki + 4 valley). 3. **No-sorry sweep** — grep the source for `sorry` to confirm which declarations carry it, matching the intended list exactly. 4. **Statement sanity check** — verify the theorem statements say what the paper claims they say (lambda_pos_finite_height_verified's statement matches R-004's claim: ∀ n, 1 ≤ n → n ≤ (3×10¹²−1)² → 0 < (liCoeff n).re, with exactly 3 hypotheses). This is the audit that matters for submission: the machine-checked STATEMENT corresponds to the paper's Theorem. 5. Check for any warnings/linter issues. 6. Check the hypothesis types: RHUpTo, LiVerifiedUpTo, SfBoundProp definitions are what we claim. 7. Verify no `axiom` declarations, no `native_decide` (which would introduce trust in the compiler — check for it), no `set_option` tricks that weaken checking (e.g., `set_option debug.skipKernelTC`... anything like that), no `@[implemented_by]`. 8. Maybe verify the zeta-23-lean inherited library is still intact (it was verified live in session 010 — a quick re-run of its audit comparator would be thorough, but that's a 9010-job build; the session-010 audit is on record. I could re-run just the PrintAxioms comparators which require the built library — the build exists, so re-running PrintAxioms on the Zeta23 comparators is cheap (no rebuild needed)). Let me plan the audit steps: **A. Clean rebuild**: `lake build NguyenRH1` (should be up-to-date or quick). Maybe force a full rebuild from scratch? A truly paranoid audit would `rm -rf .lake/build` and rebuild everything (~9010+ jobs — took how long? Session 010 did the full zeta-23 build; that was long. A from-scratch rebuild of NguyenRH1's own modules only requires Mathlib/Zeta23 oleans which are shared by path — those don't rebuild. So rm -rf .lake/build in NguyenRH1 rebuilds just the 4 modules (~8 min based on the 8700-job builds... wait, 8707 jobs INCLUDE dependencies? No — the path-required mathlib/zeta23 are prebuilt; the 8707 jobs are NguyenRH1's own module builds which somehow involve 8700 jobs? That seems to be the total job count including... whatever, builds take ~40s per module). A from-scratch rebuild of just NguyenRH1's .lake/build is cheap-ish and worth it for a submission audit. Hmm — but the Mathlib build artifacts live in zeta-23-lean/.lake — shared by path require; those stay. Deleting NguyenRH1/.lake/build only forces the 4 modules + root. That's a meaningful clean-room test of the source files. Do it. **B. sorry sweep**: grep -rn "sorry" in the package's .lean files — expect EXACTLY the 5 skeleton statements (SuzukiSkeleton: R003_exact_factorization; ValleySkeleton: 4). Also check for `admit`, `axiom`, `native_decide`, `@[implemented_by]`, `set_option ... in` weirdness, `unsafe`. **C. PrintAxioms full run**: PrintAxioms.lean covers the key declarations; extend it to be exhaustive? Current list: lambda_pos_finite_height, sInfty_lower_bound, marginTilde_convex, chain_rule_sqrt_shift, R003_exact_factorization, 4 valley, tier-(i) helpers, session-012 additions, step-2 three. That's the important ones. For a complete audit I could add every public declaration... The existing list is comprehensive for the paper-relevant claims. Maybe add a few: lambda_pos_finite_height_verified is there. What about the supporting lemmas in LiBasePoints (log80000_ge etc.)? The audit ideally covers ALL declarations. Writing a script that #print axioms EVERY declaration would need `lake env lean --run` with a meta program... Simpler: extend PrintAxioms.lean to include the remaining public lemmas of LiBasePoints + LiSkeleton's key new ones. Let me enumerate: LiSkeleton new: IIMaj_le_two_mul, IIMaj_nonneg, marginTilde_eq_sub, psiOf_T_mul_log(_neg), psiOf_log(_neg), psiOf_log_log(_neg), contDiffOn_FAlt, FAlt_psi_neg, pos_of_convex_of_base/two_points, hasDerivAt_T_mul_log, hasDerivAt_log_log_unshifted... and many tier-(i) helpers. The existing PrintAxioms has the main ones + a representative helper set. For "everything checked out and passed", the critical property: NO declaration anywhere uses anything beyond the 3 standard axioms except the 5 known sorryAx skeletons. A complete way: use Lean's environment to list all declarations in the NguyenRH1 namespace and print axioms for each — can be done with a `#eval` meta script: ```lean import NguyenRH1 open Lean #eval do let env ← getEnv for (name, _) in env.constants do if name.getRoot == `NguyenRH1 then let axioms := CollectAxioms.collect name -- Lean.CollectAxioms? ... ``` There's `Lean.collectAxioms` (used by #print axioms machinery). A meta script: ```lean import NguyenRH1 open Lean Elab Command #eval show CoreM Unit from do let env ← getEnv let mut bad := #[] for (c, _) in env.constants do if c.getRoot == `NguyenRH1 then let ax ← Lean.collectAxioms c -- name? CollectAxioms.collect? ... ``` The exact API: `Lean.CollectAxioms.collect (constName : Name) : CoreM (Array Name)`? The #print axioms command uses `Lean.collectAxioms`. Let me just write a script that iterates env.constants, filters by module/root namespace, calls collectAxioms, and reports any whose axiom set ≠ {propext, Classical.choice, Quot.sound} ∪ maybe sorryAx. That's the EXHAUSTIVE audit. I need the right API names: In Lean4 core, `Lean.collectAxioms (env) (decl) : ...`? The implementation: `Lean.Elab.Command.printAxioms` calls `Lean.collectAxioms constName` returning `Array Name` inside CommandElabM/CoreM. Let me check Mathlib/core for `collectAxioms`. I'll write the script and fix at compile. Actually simpler robust approach: the #print axioms command can be generated for every declaration name via a shell loop: extract all theorem/def names from the .lean files (grep), generate a big PrintAxioms-all.lean with one #print axioms per name, run it, and parse the output for anything unexpected. That's mechanical and reliable. grep for `^theorem NAME` etc. Let me do that. **D. Statement correspondence check**: read the final theorem statements and confirm they match the paper (the claim: ∀ n : ℕ, 1 ≤ n → (n:ℝ) ≤ (3*10^12-1)^2 → 0 < (liCoeff n).re; hypotheses exactly (RHUpTo 3e12), (LiVerifiedUpTo 5e5), SfBoundProp). Also check SfBoundProp's def matches the paper's |S_f(n)| ≤ B(n) on 10⁵ ≤ n ≤ (T₀−1)². And RHUpTo/LiVerifiedUpTo defs match their English descriptions. Report this mapping. **E. Zeta23 comparator re-audit**: re-run their PrintAxioms scripts (they exist in the vendored repo per D-061) — cheap since built. Do it if easy: D-061 §3 said "all comparator PrintAxioms scripts match AUDIT.md verbatim". Re-running confirms nothing drifted. **F. Check git cleanliness** for the lean directory (all committed) + no stray modifications. Plan of execution: 1. grep sweeps (sorry/admit/axiom/native_decide/unsafe/set_option). 2. Clean rebuild from scratch (delete NguyenRH1/.lake/build, lake build). 3. Generate exhaustive PrintAxioms (all declarations) and verify. 4. Statement correspondence table (read + report). 5. Zeta23 comparator re-run. 6. Report + commit an audit note (file it as part of the record: maybe research/derivations/D-063 or append to D-061; an audit note could go in the Lean package as AUDIT-NguyenRH1.md or a derivation). The mathematician's culture: file it. I'll write a short audit report into research/derivations/D-063-lean-audit.md and register in db. Hmm — or append to D-061 (the Lean build/audit file). D-061 is titled "lean-build-and-skeletons" with §3 = task 5.2 audit. A new D-063 "submission audit" is cleaner. Yes D-063. Start with the greps + clean rebuild (parallel-ish: rebuild first since it takes minutes; do greps while... no — Bash calls are sequential in one message but I can run greps first quickly then kick the rebuild). Actually — do greps first (fast), then the clean rebuild, then the exhaustive axiom script.
Running a full pre-submission audit of the package. Plan: (A) source sweep for forbidden constructs, (B) clean-room rebuild from scratch, (C) exhaustive axiom audit of *every* declaration, (D) statement-to-paper correspondence check, (E) re-run the inherited-library comparators, (F) file the audit report.
