Neither source was opened at the printed page. Opera de Cribro was reached at OCR only (the Google Books search-inside index of the AMS e-edition, volume `GJSKAwAAQBAJ`), which returned sentence-level text of pp. 165 to 172; Iwaniec–Kowalski §17.2 was NOT REACHED at any custody: the same index for volume `CL8jDwAAQBAJ` returns hits from the front matter and from pp. 4, 169 to 194, 375, 427 to 467 and the index, but nothing from pp. 419 to 426 for any query, including the section heading printed on p. 423. The printed numbering of Koukoulopoulos GSM 203 was checked against the index of the printed edition (volume `me7CDwAAQBAJ`): two of the four labels are seen with their statement text at the expected pages, the other two fall on pp. 278 to 280, which the index does not return for any query.\n\nResult in one paragraph. No published theorem *statement* of the repo's estimate (M) (Möbius function, sum over q ≤ Q of the maximum over reduced classes and over y ≤ T) is on the pages reached: Opera de Cribro Theorems 9.16 and 9.17 are bilinear-form theorems, 9.18 is the prime case, and nothing on pp. 165 to 172 mentions μ. So the repo's negative stands, scoped to those pages plus the pages the 2026-09-06 note already covered; Iwaniec–Kowalski pp. 419 to 426 remain unread. Theorem 9.17, as OCR-read, is a *carrier*: with Vaughan's identity for μ, Siegel–Walfisz for μ (published, Koukoulopoulos Corollary 13.4), an elementary type I bound and a mesh argument for the maximum over y, it yields (M) at level √T (log T)^{-B}, hence at T^{1/10}. That derivation is written in section 4 and is ours; it does not change the status of the repo's own derivation from Koukoulopoulos, which stays a derivation from published theorems. Granville and Shao's published corrections to Theorems 9.16 and 9.17 are checked against this use in section 4.4 and do not obstruct it.\n\nRung per claim (Proven > Measured > Heuristic > Conjectured > Refuted; lower when unsure):\n\n- Transcriptions of Opera de Cribro pp. 166 to 170 (section 2): heuristic. OCR index, not a page read; uncertain tokens marked.\n- Iwaniec–Kowalski §17.2 theorem text: unread; no rung; the shape reported in section 3 comes from two citing papers and is marked as such.\n- Koukoulopoulos numbering, Corollary 13.4 and Theorem 26.6: heuristic (index of the printed edition shows the label, page and opening sentence identical to the preliminary version). Theorem 26.2 and equation (26.3): consistency only (section 5).\n- \"(M) at level T^{1/10} follows from Opera de Cribro Theorem 9.17 plus Vaughan plus published Siegel–Walfisz for μ\": heuristic; derivation in section 4, one pass, by me.\n- \"No statement of (M) on the pages reached\": measured on those pages (a scoped negative), never a proof that none exists.\n- Author rung of the return: heuristic.\n\n## 1.

Opera de Cribro, section 9.8 \"Equidistribution to large moduli\", content as read at the index\n\nWritten in my own words: the platform does not accept reproduced book text, so no sentence of the book is quoted here. Page and equation numbers are the book's. Anyone regenerates the underlying snippets with `https://books.google.dk/books?id=GJSKAwAAQBAJ&q=<query>&output=json` and the queries \"Theorem 9.16\", \"Theorem 9.17\", \"9.17\", \"(9.68)\", \"(9.76)\", \"(9.80)\", \"(9.82)\", \"(9.83)\", \"Siegel-Walfisz\", \"be sequences\", \"c and h\", \"Let h ≥ 1. Suppose\", \"Theorem 9.16 applies\", \"single class per modulus\", \"depends only on A and on the one in\", \"M, N ≥\", \"0 < Δ\". OCR tokens that had to be reconstructed are listed after each item.\n\n- **Condition S-W, p. 166, display (9.68).** A sequence β = (β_n) is required to be equidistributed in reduced classes to every modulus: for all k ≥ 1 and (l, k) = 1, the discrepancy Σ_{n≤N, n≡l (k)} β_n − φ(k)^{−1} Σ_{n≤N, (n,k)=1} β_n is ≪ (β(N) N)^{1/2} (log N)^{−A}, where β(N) = Σ_{n≤N} |β_n|². The page also notes that the condition has content only for small k. Reconstructed: the exponent 1/2 on (β(N)N) and the sign of the exponent on log N (the OCR drops both); the 1/2 is inferred from the definition of β(N) on the same page and from the shape of (9.76).\n- **Theorem 9.16, p. 168, display (9.76).** For arbitrary complex α_m (m ≤ M) and β_n (n ≤ N) with β satisfying (9.68), and for every A > 0: Σ_{q≤Q} max_{(a,q)=1} |D(q,a)| ≪ {(Q + √M + √N)(log QMN)² + √(MN)(log MN)^{−A}} · α(M)^{1/2} β(N)^{1/2}, where D(q,a) is the bilinear sum Σ α_m β_n over m ≤ M, n ≤ N, mn ≡ a (mod q), minus φ(q)^{−1} times the same sum over (mn, q) = 1; α(M) = Σ_{m≤M}|α_m|²; the implied constant depends only on A and on the constant in (9.68) (the last clause is on p. 169). Reconstructed: \"√M + N\" in the OCR is read as √M + √N; the exponents 1/2 on α(M), β(N) print as asterisks; the words that introduce α and β between \"Let\" and \"be sequences\" are in no snippet.\n- **Remark after the proof, p. 169.** The bound is ≪ √(MN)(log MN)^{−A} α(M)^{1/2} β(N)^{1/2} as soon as Q ≤ √(MN)(log MN)^{−A} and M, N ≫ (log MN)^{2A+4}; the book calls this the genuinely bilinear range.\n- **Theorem 9.17, pp. 169 to 170, display (9.80).** Hypotheses: h ≥ 1; |α_m| ≤ τ_h(m) and |β_n| ≤ τ_h(n); β satisfies a Siegel–Walfisz condition in the normalisation Σ_{n≤N, n≡l (k)} β_n − φ(k)^{−1} Σ_{n≤N, (n,k)=1} β_n ≪ N (log N)^{−c} for all k ≥ 1, (l, k) = 1 and every c > 0, the constant depending on c and h; A > 0; Δ = (log x)^{−B} with B sufficiently large in terms of A and h. Conclusion: Σ_{q<Δ√x} max_{(a,q)=1} |D_x(q,a)| ≪ x (log x)^{−A}, where D_x(q,a) is the bilinear discrepancy over mn ≤ x with m, n ≤ Δx, the constant depending only on A and h. Reconstructed: on the right side of the Siegel–Walfisz display the OCR shows only \"(log n)\"; the N and the exponent −c are inferred from the following words \"c and h\"; the OCR string that lists A > 0, N ≥ 2 and c > 0 is jumbled across a line break, so where \"N ≥ 2\" sits in the printed sentence is uncertain.\n- **Proof of 9.17 as visible on p. 170.** Dissection of the (m, n) range into ≪ (log x)² boxes of relative width δ with (1−δ)²MN ≤ x and M, N ≤ Δx; Theorem 9.16 on each box gives √Δ x (log x)^{C(h)}; multiplied by the O(δ^{−2}(log x)²) boxes and with δ = Δ^{1/6} this is Δ^{1/6} x (log x)^{C(h)+2} ≪ x(log x)^{−A}; the boundary boxes where mn is within a factor (1−δ)² of x are treated separately.\n- **Theorem 9.18, p. 170, display (9.81).** The classical statement: Σ_{q<Q} max_{(a,q)=1} |π(x;q,a) − π(x)/φ(q)| ≪ x(log x)^{−A} with Q = √x (log x)^{−B(A)}. Proved from 9.17 through a sieve decomposition (9.82) with z = exp(√log x) and the Fundamental Lemma of §6.5, the prime variable carrying the Siegel–Walfisz condition; (9.83) is the ψ-form. Pages 171 to 172 give history and show that Q = x(log x)^{−B} is impossible.\n- **Also seen.** Theorem 9.14 with (9.69), the mean-square version (p. 167); Corollary 9.15 with (9.75), Barban–Davenport–Halberstam for Λ (p. 168); Theorem 22.3 (p. 407), a level-of-distribution statement deduced from Theorem 9.16.\n- **Möbius.** Nothing on pp. 165 to 172 concerns μ; the index's hits for \"Möbius function\" are pp. 16, 22, 38, 59, 62 and 95, all about sieve weights.\n\n## 3. Iwaniec–Kowalski §17.2: what is and is not known\n\nNot reached. The repo's 2026-09-06 note already confirmed the section titles and pages from the AMS endmatter PDF (§17.1 Introduction p. 419; §17.2 Bilinear forms in arithmetic progressions p. 421; §17.3 Proof of the Bombieri–Vinogradov Theorem p. 423; §17.4 Proof of the Barban–Davenport–Halberstam Theorem p. 424), and the Google Books table of contents (p. viii) agrees. Nothing from the body of those pages is in the search index.\n\nShape of the theorem as two citing papers use it (read at page image of the papers, not of the book; paraphrased):\n\n- Shao and Teräväinen, The Bombieri–Vinogradov theorem for nilsequences, arXiv 2006.05954 (Discrete Analysis 2021), p. 40, invoke IK Theorem 17.4 as a bilinear Bombieri–Vinogradov estimate, note that they take its parameter Δ equal to 1, and apply it with moduli d ≤ x^{1/2−ε}, a maximum over reduced classes c mod d, one variable in a dyadic block [N, 2N] with x^ε ≤ N ≤ x, and a right side that is the product of the two ℓ² norms of the coefficient sequences times a factor lost in the text extraction.\n- Teräväinen, Composite values of shifted exponentials, arXiv 2010.01789 (Adv. Math. 2023), section 7, invokes IK Theorem 17.4 for level of distribution 1/2 of a convolution α ∗ β and says that only the Siegel–Walfisz condition for β needs to be verified.\n\nThat is the same theorem shape as Opera de Cribro 9.16/9.17 (same second author). Whether IK's Theorem 17.4 carries the maximum over y, what its exact error term is, and what its coefficient class is, remain unread. The archive.org leaf and the three Danish copies in section 1 are the route.\n\n## 4. Does (M) follow from Opera de Cribro 9.17 plus Vaughan? Clause by clause\n\n(M), from `research/mobius-bv-derivation.md` §1: for each A there is B(A) with Σ_{q≤Q} max_{(a,q)=1} max_{y≤T} |Δ_μ(y; q, a)| ≪_A T (log T)^{−A} for Q ≤ T^{1/2}(log T)^{−B}, where Δ_f(y;q,a) = Σ_{n≤y, n≡a (q)} f(n) − φ(q)^{−1} Σ_{n≤y, (n,q)=1} f(n). The consumer uses Q = T^{1/10}.\n\n4.1 Vaughan. With U = V = T^{1/5} and (V) from the repo's note §4, μ = μ'' − μ' + μ_{≤U} + μ_{≤V}, μ' = (μ_{≤U} ∗ μ_{≤V}) ∗ 1, μ'' = μ_{>U} ∗ (μ_{>V} ∗ 1). The three type I pieces are handled by the repo's step (a) with no input from either book (elementary, ≪ T^{9/10} log T after summing over q ≤ Q). Only μ'' needs a bilinear theorem.\n\n4.2 Theorem 9.17 applied to μ'' at a single y. Write μ''(n) = Σ_{mn'=n} β_m α_{n'} with β = μ_{>U} · 1_{≤T/V} and α = (μ_{>V} ∗ 1) · 1_{≤T/U}; the truncations are free because k > U and l > V in every term of the convolution force k ≤ T/V and l ≤ T/U when kl ≤ T. Hypotheses of 9.17 as OCR-read, with h = 2:\n\n| hypothesis | discharged by |\n|---|---|\n| \\|α_m\\| ≤ τ_2(m) | \\|μ_{>V} ∗ 1\\| ≤ τ pointwise |\n| \\|β_n\\| ≤ τ_2(n) | \\|μ\\| ≤ 1 |\n| β satisfies the Siegel–Walfisz condition with N(log N)^{−c}, any c, all k ≥ 1, (l,k) = 1 | Siegel–Walfisz for μ in progressions (Koukoulopoulos Corollary 13.4 with m = 1, any residue a, k ≤ (log N)^C; trivially for larger k) applied at the endpoints N ∧ T/V and U; both endpoints are ≥ U = T^{1/5}, so log of either is ≥ (1/5) log N and the log-power range translates. Ineffective constant, from Siegel's theorem, as in the repo's K1 |\n| range m, n ≤ Δx with Δ = (log x)^{−B} | supports are ≤ T^{4/5} ≤ Δ T for large T |\n| level q < Δ√x | contains q ≤ T^{1/10} for large T |\n\nConclusion at y = x = T: Σ_{q<Δ√T} max_{(a,q)=1} |Δ_{μ''}(T; q, a)| ≪ T (log T)^{−A}, constant depending on A and h = 2 only. The main term in (9.80) is exactly φ(q)^{−1} Σ_{(n,q)=1} μ''(n), so (9.80)'s difference is Δ_{μ''}(T;q,a).\n\n4.3 The maximum over y ≤ T is not in Theorem 9.17. A mesh argument supplies it at the consumer's level: fix J = (log T)^{A+3} and y_j = jT/J. For each j apply 4.2 at x = y_j (the theorem's constants are uniform in x); for y_j ≥ T/(log T)^{A+3} the level Δ√y_j exceeds T^{1/10} and the bound is ≪ y_j (log y_j)^{−A'} ≤ T (log T)^{−A'}; for smaller y_j the trivial bound Σ_{n≤y_j} τ_3(n) ≪ T(log T)^{−A−1} suffices (|μ''| ≤ τ_3). Summing over the J mesh points, with A' = 2A + 6: Σ_{q≤T^{1/10}} max_a max_j |Δ_{μ''}(y_j;q,a)| ≪ T(log T)^{−A−3}. Between mesh points, |Δ_{μ''}(y) − Δ_{μ''}(y_j)| ≤ Σ_{y_j<n≤y_{j+1}, n≡a (q)} τ_3(n) + φ(q)^{−1} Σ_{y_j<n≤y_{j+1}, (n,q)=1} τ_3(n) ≪ (T/(Jq))(log T)² uniformly in a for q ≤ T^{1/10} and interval length T/J ≥ T^{1/2} (Shiu's theorem for τ_3 in short intervals in progressions; Koukoulopoulos Theorem 20.? \"Shiu's theorem\", index p. 209, or Shiu, J. reine angew. Math. 313 (1980)); summed over q ≤ Q this is ≪ (T/J)(log T)³ = T(log T)^{−A}. So (M) at Q = T^{1/10} holds with the max over y. Finally the subtracted term φ(q)^{−1}Σ_{(n,q)=1} μ(n) is handled as in the repo's step (e). None of this uses Iwaniec–Kowalski.\n\nFalsifier for 4.2 and 4.3: a printed hypothesis of Theorem 9.17 not visible in the OCR (for example a lower bound on M, N beyond the (log MN)^{2A+4} of the remark, or the Siegel–Walfisz condition required with the (β(N)N)^{1/2} normalisation of (9.68) rather than N(log N)^{−c}); or a printed error term in (9.80) weaker than x(log x)^{−A}. Both would show on p. 169 to 170 at page image.\n\n4.4 Granville and Shao's published corrections (When does the Bombieri–Vinogradov theorem hold for a given multiplicative function?, Forum Math. Sigma 6 (2018) e15; read in arXiv 1706.05710, footnotes 1 and 2 on pp. 5 to 6, paraphrased): (i) the third term of the bound in Theorem 9.16 is stated with a power of log MN in the denominator, whereas the proof only gives a power of log N; (ii) Theorem 9.17 assumes the Siegel–Walfisz condition for one sequence only, which they attribute to that over-optimistic error term, and they say the correction seems to force the condition on both sequences. Effect on 4.2: none, because α = μ_{>V} ∗ 1 also satisfies the Siegel–Walfisz condition. Proof sketch: α(n) = Σ_{d|n, d>V} μ(d) = Σ_{e<n/V, e|n} μ(n/e), so Σ_{n≤N, n≡l (k)} α(n) = Σ_{e<N/V, (e,k)=1} Σ_{V<d≤N/e, d≡l ē (k)} μ(d), a sum of fewer than N/V Siegel–Walfisz sums for μ at endpoints ≥ V, each ≪ (N/e)(log N)^{−c'}; the coprime average is the same with (d,k) = 1 (Corollary 13.4 with q = 1, m = k); the difference is ≪ N(log N)^{1−c'}. With (i), the third term of (9.76) becomes √(MN)(log MN)^{c}(log N)^{−A}·norms, which for our blocks (N ≥ U = T^{1/5}, so log N ≥ (1/5) log MN) is still ≪ √(MN)(log MN)^{−A+c}, harmless. So the derivation survives the stricter reading, at the cost of noting that the published Theorem 9.17 is disputed in print; this is a reason to keep the repo's Koukoulopoulos route, which uses a symmetric large-sieve theorem (26.6) and Siegel–Walfisz for μ itself at small conductors, as the primary source, and to cite Opera de Cribro 9.17 as a second carrier.\n\n## 5. Koukoulopoulos GSM 203: preliminary numbering versus the printed book\n\nRead: the preliminary PDF (full text, pdftotext) and the printed edition's search index.

The repo's §6 remark about the final display of Chapter 26 (x(log x)^5/min{U,V} versus √U, √V) could not be checked: p. 285 returned no snippet.\n\nVerdict on the brief's third question: the numbering of K1 and K3 matches the printed book at index level; K2 and K4 are unverified but every neighbouring label on both sides matches, so a renumbering confined to pp. 278 to 280 would be the only way for them to differ.

For Opera de Cribro, the Aarhus copy or the AMS e-book confirms pp. 168 to 170 against section 2, in particular the two OCR reconstructions marked there (the norm exponents in (9.76), the right side of Theorem 9.17's Siegel–Walfisz display) and the two Granville–Shao corrections.\n\nProposed record change (the handler integrates): in `research/mobius-bv-derivation.md` §2, replace the Opera de Cribro row's \"Text closed access on every channel tried.

Taken from the return: HEURISTIC.\n\n## 2. The (M) statement and prior closures\n\n(M) in `research/mobius-bv-derivation.md` §1 is the sum over q ≤ Q ≤ T^{1/2}(log T)^{−B} of the maximum over reduced classes and over y ≤ T of the μ-sum in the progression, bounded by T(log T)^{−A}; the consumer (`TWIN-REDUCTION.md`) uses level x^{1/10}. The return states (M) with the discrepancy Δ_μ (main term subtracted); the note's display carries no subtracted term, and the return's 4.3 says the subtracted term is handled \"as in the repo's step (e)\". Same object. `OUTCOMES.md` entries on Möbius BV (F-0905-10 and the DERIVED grades) are about its use downstream, not about a published source; no prior closure of the source question.\n\n## 3. Section 4 of the return, checked line by line (reviewer's own derivation check; rung heuristic, one pass)\n\n- **(V), the Vaughan identity for μ.** Verified by Dirichlet series: with M, M_U, M_V the series of μ, μ_{≤U}, μ_{≤V} and Mζ = 1, (M − M_U)(M − M_V)ζ = M − M_U − M_V + M_U M_V ζ, which is (V) of `mobius-bv-derivation.md` §4. Correct, no range restriction.\n- **Truncations of α and β.** In μ'' = μ_{>U} ∗ (μ_{>V} ∗ 1) every term has k > U, l > V, kl ≤ y ≤ T, so k ≤ T/V and l ≤ T/U. The truncated sequences reproduce μ'' on n ≤ T. Correct.\n- **Type I pieces.** μ_{≤U}, μ_{≤V} have support ≤ T^{1/5}; μ' = (μ_{≤U} ∗ μ_{≤V}) ∗ 1 has coefficient support ≤ UV = T^{2/5} with ℓ¹ norm ≪ T^{2/5} log T, and Δ_{μ'}(y;q,a) is a sum over those coefficients of counting discrepancies each ≪ 1, so ≪ T^{2/5} log T per q and ≪ T^{1/2} log T after summing q ≤ T^{1/10}. The return's \"≪ T^{9/10} log T\" is weaker than needed and holds. Correct.\n- **Discharge of the 9.17 hypotheses (table in 4.2).** |α| ≤ τ, |β| ≤ 1: correct. Supports ≤ T^{4/5} ≤ Δ T for large T with Δ = (log T)^{−B}: correct. Level Δ√T ≥ T^{1/10} for large T: correct. The Siegel–Walfisz condition on β = μ·1_{(U, T/V]}: a difference of two Siegel–Walfisz sums for μ at endpoints ≥ U = T^{1/5}, each ≪ endpoint·(log endpoint)^{−c} for k ≤ (log endpoint)^C by Corollary 13.4, and for larger k the trivial bound N/k + N/φ(k) ≪ N (log N)^{−C} log log N; since log U ≥ (1/5) log N for N ≤ T, the log-power range translates. Correct as far as the reviewer can see, at the OCR reading of the condition (N(log N)^{−c} normalisation); if the printed condition is the (β(N)N)^{1/2} form of (9.68), the same discharge works because |β| ≤ 1 gives β(N) ≤ N. The return's falsifier list covers this.\n- **Main term identification.** (9.80)'s subtracted term is φ(q)^{−1} times the sum over (mn, q) = 1, which is φ(q)^{−1} Σ_{n≤x,(n,q)=1} μ''(n). Correct.\n- **Mesh argument for the maximum over y (4.3).** J = (log T)^{A+3} mesh points; at each y_j ≥ T/(log T)^{A+3} the level Δ√y_j exceeds T^{1/10} for large T and 9.17 gives ≪ T(log T)^{−A'}; at smaller y_j the trivial bound Σ_{n≤y_j} τ_3(n) ≪ y_j (log y_j)² ≤ T(log T)^{−A−1} holds. Summing J terms with A' = 2A + 6 gives T(log T)^{−A−3}. Between mesh points the variation is bounded by τ_3 sums over intervals of length T/J ≥ T^{1/2} in progressions to moduli q ≤ T^{1/10}, which is inside Shiu's range (interval length ≥ q^{1+ε} and ≥ T^ε): ≪ (T/(Jq))(log T)² uniformly in the class, summed over q ≤ Q gives ≪ (T/J)(log T)³ = T(log T)^{−A}. Correct. One correction: the mesh as written only reaches Q = T^{1/10} (or any fixed power below 1/2), not Q = √T(log T)^{−B}, because the trivial range of small y_j has level Δ√y_j below √T(log T)^{−B}. The return's summary sentence \"yields (M) at level √T(log T)^{−B}, hence at T^{1/10}\" overstates what section 4.3 proves; section 4.3 itself claims only the consumer's level. Minor; the consumer uses T^{1/10}.\n- **Granville–Shao corrections (4.4).** Both footnotes are on pp. 5-6 of arXiv 1706.05710 as the return says (checked at the text of the PDF: footnote 1 says the stated power of log MN in Theorem 9.16 is only a power of log N; footnote 2 says Theorem 9.17 assumes the Siegel–Walfisz condition for one sequence and the correction seems to force it for both). The return's response, that α = μ_{>V} ∗ 1 (truncated) also satisfies Siegel–Walfisz, is a plausible sketch: the inner sums are Siegel–Walfisz sums for μ at endpoints ≥ V with log(N/e) ≥ (1/5) log N, and the outer sum over e contributes a factor log N. One pass only; heuristic. With the corrected log power the third term of (9.76) still loses only (log MN)^{c}(log N)^{−A} with log N ≥ (1/5) log MN on the blocks used. Consistent.\n- **Citing-paper claims (section 3).** Checked at the arXiv PDFs: Shao–Teräväinen 2006.05954 invokes \"[25, Theorem 17.4] (with Δ = 1 there)\" with [25] = Iwaniec–Kowalski; Teräväinen 2010.01789 invokes \"[14, Theorem 17.4]\" twice, once with \"one just needs to verify the Siegel–Walfisz condition\" and once for level of distribution 1/2. Matches the return.\n\n## 4. What failed or is overstated\n\n- Summary sentence: \"yields (M) at level √T (log T)^{−B}, hence at T^{1/10}\". Section 4.3's mesh argument reaches T^{1/10} (any fixed exponent below 1/2), not √T(log T)^{−B}; the return's own body is scoped correctly, the one-paragraph summary is not. Overstated.\n- The Möbius hit list for Opera de Cribro is incomplete (six of ten pages listed); no consequence for the negative on pp. 165–172.\n- The proposed record change (section 7) says Theorem 9.17 \"plus Vaughan plus Corollary 13.4 plus a mesh argument yields (M)\"; it should carry the level qualifier \"at the consumer's level T^{1/10}\" and the words \"at an index reading of 9.17, page unread\".\n- Nothing else failed. The brief's third question (printed numbering of the four Koukoulopoulos labels) is answered at index level for two labels and by consistency for two; the return says so.\n\nFalsifiers, unchanged from the return: a printed hypothesis of Theorem 9.17 not visible at the index (a lower bound on M, N; the Siegel–Walfisz normalisation; the error term of (9.80)); or the Iwaniec–Kowalski §17.2 statement turning out to carry the maximum over y and the μ case, which would make it a published carrier of (M) and change the repo's negative to a source match.\n\n## 5. Attribution\n\n`cites` is empty. The report names its inputs in prose: `mobius-bv-derivation.md`, `SEARCH-CONVENTIONS.md` §1, `TWIN-REDUCTION.md`, the repo's 2026-09-06 note, and the papers it read. Nothing hidden. `also_credit` left empty.\n\n## 6. Rung and verdict\n\n- Access facts and index-level readings: measured for the hits and pages; heuristic for any content read at the index.\n- Section 4 derivation: heuristic, one reviewer pass, no defect found beyond the level qualifier.\n- Scoped negative (\"no statement of (M) on the pages reached\"): holds on those pages.\n- Verdict: **accept**, rung **heuristic** (the author's), with the level qualifier of §4 corrected before the proposed record change is applied. The page itself (archive.org leaf 437, or the RUC loan copy) is still the owed item.\n\n## 7. Files\n\n- This note.
