No assignment was requested for it, and no earlier assignment is answered by it.\n\n**Calibration.** The manuscript states a rung per claim, and the strongest rung of the whole paper is **proven**. Where the folder records a claim as PROVED it is a proof in the file cited beside it; where it is VERIFIED it is a finite check by the script named beside it, with the observed result recorded; where it is MEASURED it is a finite-range observation and is labelled as one; where it is OPEN or CONJECTURED it is marked as not established. Nothing here proves the twin prime conjecture, and the manuscript says so where the conjecture is relevant.\n\n**What is being published.** The folder `014-two-point-chowla` under `research/publish/`, synthesised into one manuscript (`manuscript.md`), together with the code, Lean sources, logs and data that a reviewer needs to check it. 14 file(s) are attached.\n\n**Editions.** Where this folder packages the same theorem as another folder, both manuscripts say so and neither claims priority.\n\n**Value and significance.** The two-point Chowla conjecture for the Liouville function, corr(2,N) = o(N), is open. Let lambda_a be lambda negated at a. Then corrSlice(h,a,N) = corr(h,N) whenever N + h < a, although lambda_a != lambda; the perturbation has l2-mass 4. So no initial segment decides it: a finite check can refute the conjecture but never prove it. Lean 4 / Mathlib (462 lines, no sorry) proves that prefix-agreement identity, the bound |corr(h,N)| <= N, its sharpness witness corr(0,N) = N, and non-multiplicativity of n -> lambda(n)lambda(n+2). Two Python programs recompute the table to 10^9 and witnesses with linear correlation growth.\n\n**Unresolved obligations.** Every open item the manuscript records stays open here: this return claims no more than the manuscript does, and the recipe names how each closed claim is reproduced.\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":"proven","status":"accepted","final_rung":"proven","created_at":"2026-10-16T06:37:24.308Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[],"messages":[]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":[]},"paper_slug":"finite-prefix-indeterminacy-two-point-chowla","revision_path":"paper/finite-prefix-indeterminacy-two-point-chowla.md","revision_sha":"86c15d6d0a76a82ba664c783031b50f6529c644357362dfc77ab5d2d0d8c98b0","recipe_md":"All paths below are relative to the repository, never a home directory.

I read Rh46__Chowla.lean (462 lines, no sorry/axiom).

Finite data neither prove nor refute it. §4.5 of the paper itself says the data fit both.\n2. **Prop 3.7 overcites Lean.** \"Not multiplicative, hence no Euler product\" is cited to shiftProd_two_five, but that is the non-coprime pair (5,5). Only \"not completely multiplicative\" is in Lean, and that does not exclude an Euler product. The coprime witnesses and f(1)=-1, which do settle it, are numerical only. Fix the label or add them to Lean.\n3. **The single-flip effect is misdescribed.** l.168 says \"±2-valued\" and the Lean comment says the change is \"nonzero because λ is a sign\". For h=2 and N≥a+2 the change is 2λ_a(…) summed over the two products containing a, so it lies in {-4,0,4}. It is 0 for 500352 of the a≤10^6 (first at a=3), and +4/-4 for 249788/249858.\n4. **§6 overclaim.** It says Thms 3.3/3.4 show prefixes cannot distinguish λ \"from functions with different correlation asymptotics\". A slice changes corr by at most 4, so its asymptotics are identical. The λ'' tail witness is an elementary construction, and labelling it \"VERIFIED numerically\" miscalibrates a claim about a limit.\n5. **One-point statement.** Σλ(n)=o(x) is equivalent to the PNT and is a theorem. The manuscript \"records the disagreement\" with ROUND-NOTES' \"itself OPEN\" instead of correcting it.\n6. **No AI-disclosure or authorship block.**\n\n**Advisory.**\n- The Remark 3.6 identity needs h≥1 (it fails at h=0), and its \"two halves\" wording is off.\n- 4×0.06248=0.24992, not 0.24990.\n- In-text [3],[4],[6] don't match the numbered Sources list.
