From a29f1075a15be4b620815c8c87f3f54923be8d35 Mon Sep 17 00:00:00 2001 From: Vasily Ilin Date: Tue, 28 Jul 2026 02:08:46 -0700 Subject: [PATCH 1/4] LLM review: check what the gates can't, and route non-content PRs away MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An audit of all 148 reviews the bot has posted, against what actually happened to those PRs, says the project review is looking in the wrong place. Three findings drove this change. **It approved a duplicate.** #275 (de Bruijn-Erdos compactness) came back `approve` / `good_fit` / 0 findings and was closed by hand: the headline follows in a few lines from Mathlib's `Finsubgraph`. #225 was likewise subsumed by the pool's own `Incompleteness`. `REVIEW_RULES.md` has never had a duplication check — only the challenge rules do — so the model had no way to reach the reason both PRs were rejected. **It cannot see what the axiom gate misses.** #225's diagonal lemma was postulated as an `inductive` constructor, invisible to `#print axioms`; the review filed it as a card-wording nit. The same class covers #215 (a rescaled surrogate tableau proved in place of the real one), #240 (a card informal that was simply false), #265 (a synthetic residue model presented as the geometry it models), and #199 (NP-hardness claimed for a reduction-correctness result). Every defect human audits have caught here lives in the gap between what the card claims and what the Lean proves, and nothing in the rules asked about it. **Infra PRs were graded for mathematical fit.** A `.lean` file under `scripts/` clears the workflow's "touches Lean?" filter, so the exposition PRs landed on the project rules: #279 and #282 came back `not_a_fit` / `undergraduate`, #283 came back `good_fit` / `graduate` / `approve` over a summary opening "This is not a mathematics contribution." All three merged. `classify_pr` now returns `infra` for these and posts a note instead of calling the model. So the project rules gain the four checks the challenge rules already had, adapted for finished proofs — claim-vs-Lean faithfulness, what is assumed rather than proved, prior art, and source fidelity — plus the generated-bulk criterion #278 was closed on after a 0-finding approval, and an AI-slop list, since half the pool is AI-written and fluent prose is not evidence. Comparable projects converge on the same shape: Tau Ceti gates on `correctness` and `reuse` before anything else and tells its reviewers not to defer to plausible-looking work; ArkLib forbids a docstring from being the sole basis of a correctness claim. Two calibration fixes fall out of the same audit. `obscure_problem` was `no` in all 147 project reviews and is gone; card metadata moves to out-of-scope, since `quality.py` gates it and #216 and #243 were rejected on nothing else and merged unchanged; a partial review may no longer `approve`, because `code_quality` cannot be scored on elided files; and the sticky comment now says plainly that `request_changes` is an ask, not a close — 39% of those verdicts were merged after a human looked, while 20 of 28 closures cited the bot. Two of the four approve-calibration examples (sphere packing, Erdos 124) were not in the pool at all. Replaced with real slugs, and with the pool's actual size distribution. Separately, the reviewer now receives the PR title and description. The rules have always allowed a source anchor to live in the "PR description", which the model was never shown. Because that text and the diff are both contributor-written — and the pool accepts AI-generated projects by design — they are fenced with a per-request random token and framed as claims to verify, never as instructions.

That is your job, and it is where every defect a human audit has caught in this repository has lived. + +### 1. Does the Lean prove what the card claims? + +The card's `main_results` pair each headline `declaration` with an `informal` English statement, and the module docstring restates the same claim. Read the Lean statement of each main declaration against its informal text, quantifier by quantifier: + +- Are the quantifiers in the right order, over the right domains? +- Are the hypotheses the intended ones — nothing extra that trivializes the result, nothing missing that would make it false? +- Is the conclusion the intended one, not a weaker cousin? (A bound proved for one fixed parameter is not the bound "for all n"; an existence statement is not a classification.) +- Do the Mathlib definitions mean what the prose means, and do the coercions do what it says? (`Set.Infinite` vs `Set.Nonempty`; `(4 : ℚ) / n` vs truncated `4 / n` on `ℕ`.) +- Does the project prove the object it names, or a **surrogate** for it — a rescaled, discretized, or synthetic model standing in for the real one? A theorem about a residue model is not a theorem about the geometry it models, however close the analogy. + +Overclaiming is the single most common real defect here, and it is usually in the *prose*, not the Lean: the theorem is honest, the summary is not. When they disagree, say which is right and quote the Lean. + +Because of that asymmetry, **a docstring is never evidence.** Cards, module docstrings, and comments are exactly what goes wrong, so a claim that something is proved has to rest on the Lean statement itself. If the only thing supporting a finding — in either direction — is prose, say so instead of concluding. + +Where a headline is an inequality or a bound, instantiate it at the edges of its stated regime before believing it. Lean's division and subtraction are total (`x / 0 = 0`, truncated `ℕ` subtraction), so a bound can be faithful across the interesting range and vacuous or false exactly at a boundary the source includes — an empty index set, a zero denominator, `n = 0` or `n = 1`, an infinite measure. + +### 2. What is assumed rather than proved? + +The axiom audit is blind to this. Content can be postulated with no `axiom` keyword anywhere: + +- **Bundled hypotheses.** A headline theorem whose real content sits in its hypotheses — published results taken as parameters rather than formalized. This is legitimate and common here, but only when the card says so plainly. A conditional result presented as an unconditional one is a defect; a conditional result whose conditionality is stated in the summary is fine. +- **Postulated structure.** An `inductive` constructor, a `structure` field, or a class axiom that simply asserts the hard step. A field with a plausible mathematical name is still an assumption. This is invisible to `#print axioms`, so nobody downstream will catch it. +- **Unexercised predicates.** A new `Prop`-valued definition, class, or hypothesis bundle with neither a consuming theorem nor a nontrivial witness in the PR. Until one exists, whether it says the right thing is unfalsifiable — ask for the witness or the consumer. +- **Vacuity.** Hypotheses that cannot be satisfied simultaneously make a theorem trivially true. Where the hypotheses are elaborate, look for evidence they are satisfiable — a witness, an instance, a construction. Pin a key predicate from both sides where you can: a definition that has both an existence lemma and a uniqueness lemma cannot be trivially `True` or trivially `False`. + +Say what is assumed and whether the card discloses it. "Proves X conditional on Y and Z, both stated in the summary" is a complete and often approving answer. + +### 3. Is it already done? + +Duplication is not machine-checked here — there is no dedup gate — and the pool now holds 141 projects, so it is worth a minute. Ask whether the headline result is already in Mathlib, or already in the pool under another name, and say so with the declaration name if you can. A project that restates `Mathlib`'s compactness argument for graph colorings, or that reproves what a pooled project already derives, is a reject however good the Lean is. + +Not every overlap is duplication: a different proof of a known theorem, a sharper constant, a generalization, or a restatement in a genuinely different setting can all be worth having. Distinguish, and name what is new. If you cannot check, say `unverifiable` rather than guessing in either direction. + +### 4. Does the cited source say what the PR says it says? + +When the card cites a paper, textbook, or named problem, check that the citation supports the claim: right theorem, right hypotheses, right attribution. Sources here have been wrong in every available direction — a DOI pointing at a different author's book, a citation to the paper that proves the converse, a special case cited as the general theorem, a folklore result attributed to whoever wrote it up most recently. If the diff does not let you verify it, say `unverifiable`. + +Also watch for uncredited prior formalizations. Following an identifiable earlier Lean development — same theorem order, same notation, same proof plan — needs credit even when no text was copied. + +A project may knowingly prove something other than the cited theorem — a generalization, a special case, a variant with different hypotheses. That is fine, and often the point. What is not fine is presenting it as the cited result. Ask that the difference be *labelled*, not removed. + +### 5. AI-slop tells + +Half the pool is AI-written and the good ones are indistinguishable from human work, so judge the artifact rather than the provenance. But these patterns are worth a look in an `AI` or `mix` project, because they survive a green build: + +- Hypotheses a theorem never uses, or typeclass assumptions far stronger than the proof needs (`[Field F]` where `[Semiring R]` would do). +- Near-duplicate definitions of the same object under two names, or a lemma restated a second time with the arguments permuted. +- Imports and `open`s that have nothing to do with the subject — residue from an `exact?` search. +- `@[simp]` on a lemma whose left-hand side is not in simp-normal form. +- A linter or elaboration problem suppressed rather than fixed. `set_option linter.X false` in project code is a defect even where the option itself is permitted, because it hides the thing the linter found. ## Calibration +Sizes, for scale: the median pooled project is about 2,800 lines of Lean, the tenth percentile about 900, and only four of 138 are under 500. Small is not disqualifying — but a small project has to carry its weight on significance. + **Approve PRs like:** -- Vlasov-Maxwell-Landau steady-state classification (~10K LOC, paper-anchored, multi-file, named main theorem). -- Formal Learning Theory kernel (~22K LOC, dozens of files, several named major theorems with paper backing). -- Sphere packing in dimensions 8 and 24 (Viazovska's published work). -- A complete formalization of Erdős Problem 124 — small (~1K LOC) but research-level, named open problem. +- `clawristotle` — Vlasov-Maxwell-Landau steady-state classification (~10K LOC, paper-anchored, multi-file, named main theorem). +- `formal-learning-theory` — Formal Learning Theory kernel (~19K LOC, dozens of files, several named major theorems with paper backing). +- `hadwiger-nelson-bounds` — kernel-checked 5 ≤ χ(ℝ²) ≤ 7 for the plane-coloring problem: a named open problem, honestly bounded rather than claimed solved. +- `erdos132-n14` — ~2K LOC on a fourteen-point case of Erdős 132, conditional on two published inputs, with the conditionality stated in the summary and the general problem explicitly left open. +- `sensitivity`, `circuit-complexity`, `pumping-cfg` — theoretical computer science held to the same bar. **Reject PRs like:** - "add binomial PMF corollaries" — two trivial corollaries, agent churn. - "generalize binomial addition with additive convolution API" — incremental refactor, no headline. -- 176-line single-lemma PR proving binomial-PMF additivity with no anchor — undergrad probability identity, however gnarly the proof. +- A 176-line single-lemma PR proving binomial-PMF additivity with no anchor — undergrad probability identity, however gnarly the proof. +- A clean, well-written formalization of de Bruijn–Erdős compactness whose main content Mathlib already has (`Finsubgraph`) — good Lean is not a reason to merge a duplicate. +- A project whose key step is a `structure` field or `inductive` constructor asserting the thing to be proved, especially when a pooled project already derives it honestly. + +## When there is no project in the PR + +A PR whose Lean is all tooling never reaches you — it is routed away before a model is called.
