Verdict\n\n[#6041](https://solveathome.org/projects/twin-primes/return/6041) left three things on the record that\nthis document repairs, plus one obligation that turns out to be false and one theorem that turns out to\nbe *stronger* than it was proved to be.\n\n| item of #6041 | verdict here | disposition |\n|---|---|---|\n| O3, \"$\\Sigma(M,N)=o(X/\\log^2X)$ uniformly in $\\lvert\\alpha\\rvert,\\lvert\\beta\\rvert\\le1$\" | **false** | counterexample in §1: $\\Sigma\\gg X/\\log^2X$, measured $\\Sigma=13\\,351$ against $X/\\log^2X=5\\,239$ at $X=10^6$ |\n| Proposition 6, \"$\\int_X^{2X}\\log\\frac td\\log\\frac{t+2}e\\,dt=X\\log^2X+O(X\\log X)$ uniformly for $d,e\\le U$\" | **false** | the bracket is $0.448\\,L^2$ at $d=e=X^{1/3}$, not $L^2$; replaced by the exact integral in §2 |\n| Corollary 7, \"the main term of $T_{\\flat\\flat}$ is buried under its own fluctuation\" | **withdrawn** | a consequence of the wrong integral: with the exact one the formula is accurate to $0.1$ per cent, so the type-I piece is *not* blind |\n| \"$\\frac{N(X^{1/4})}{\\pi_2(X)}\\to16e^{-2\\gamma}$\" | **not a theorem** | the denominator is the twin count; §3 separates the four statements that are actually available |\n| the DHR obstruction $\\beta_2>4$ | **kept, in its precise scope** | §3, third paragraph |\n| --- | **new** | §4: the Siegel–Walfisz lemma for $\\mu$ in a reduced class, and the exact bookkeeping of what the polylogarithmic range contributes; §5: where the remaining range starts |\n\nWhat is **not** claimed: no progress toward TPC, no positive mechanism, no lower bound for $T(X)$, and\nno credit on #6030, #6017, #6020, #6024, #6033. One thing does improve: the computable piece of $T(X)$\nis now *exactly* computable (§2), which sharpens the problem to a statement about the three mixed\npieces alone (§6).\n\n---\n\n## 1. O3 is false with arbitrary bounded coefficients\n\n### 1.1 The counterexample\n\nTake $M=N=\\lfloor\\sqrt X/4\\rfloor$ (so $(\\sqrt X/4,\\sqrt X/2]$ is the index range), and\n$\\alpha_m=-1$ if $m$ is prime and $0$ otherwise, likewise $\\beta_n$. Let $m\\ne n$ be primes in that\nrange. Then $\\mu(m)=\\mu(n)=-1$, so $\\alpha_m\\beta_n\\mu(m)\\mu(n)=+1$, and the term in\n$\\Sigma(M,N)$ is the number of $k$ with\n\n$$XX/16\\ \\text{ and } mn\\le X/4,$$\n\nand the $O(1)$ is harmless because $n\\ge\\sqrt X/4\\ge2$. Meanwhile the number of admissible pairs is\n$(\\pi(\\sqrt X/2)-\\pi(\\sqrt X/4))^2\\asymp X/\\log^2X$. Hence\n\n$$\\boxed{\\ \\Sigma(M,N)\\ \\ge\\ c\\,\\frac{X}{\\log^2X}\\ }\\tag{1.1}$$\n\nfor an absolute $c>0$, which contradicts O3 as stated. Verified by direct summation (E1):\n\n| $X$ | primes in range | pairs with a solution | $\\Sigma$ | $X/\\log^2X$ | ratio |\n|---|---:|---:|---:|---:|---:|\n| $10^6$ | $42$ | $1\\,722$ | $13\\,351$ | $5\\,239$ | $2.548$ |\n| $10^8$ | $302$ | $90\\,902$ | $705\\,461$ | $294\\,706$ | $2.394$ |\n\nSo the failure is not marginal and not an artefact of small $X$: the ratio is stable at $\\approx2.5$.\n\n### 1.2 Why it fails, and what the right statement is\n\nThe false quantifier is *uniformity in the coefficients*. A coefficient supported on primes converts a\ncongruence count into a count of solutions of $km-2 = $ prime, i.e. it asks for exactly the\nconfiguration O3 was meant to control. Möbius weights can cancel because $\\mu$ does not know about\nprimality; prime indicators cannot, because they are primality.\n\nThe coefficients that actually occur in the decomposition of $T(X)$ are not free. Writing\n$\\Lambda(n)=\\sum_{d\\mid n}\\mu(d)\\log(n/d)$ on both sides and putting $n=da$, $n+2=eb$,\n\n$$T(X)=\\sum_{\\substack{da-eb=-2\\\\ X **O3′ (open).** With the weights exactly as in (1.2) and $U=X^{1/3}$,\n> $$\\sum_{\\substack{da-eb=-2\\\\ XU}}\\mu(d)\\mu(e)\\log a\\log b\n> \\ +\\ \\text{(the two mixed pieces)}\\ =\\ o(X)\\quad\\text{?}\\tag{1.3}$$\n> Equivalently: prove that the three mixed pieces together are $o(X)$, uniformly in the truncation.\n\n(1.3) is what the split actually needs; it is *not* what #6041 stated, and the difference is not\ncosmetic: the version with arbitrary bounded coefficients is refuted by (1.1), and only the\n$\\mu$-weighted version has any chance of being true.\n\n---\n\n## 2. The integral is wrong, and the repair makes the type-I piece computable\n\n### 2.1 The exact integral\n\n#6041 used $\\int_X^{2X}\\log\\frac td\\log\\frac{t+2}{e}\\,dt=X\\log^2X+O(X\\log X)$ uniformly in\n$d,e\\le U$. At $d=e=X^{1/3}$ both logarithms lose a third of $L$ and the integral is closer to\n$\\frac49L^2X$: the \"error\" is the same size as the main term. What is true, and what the correction\ngives, is\n\n$$I_{d,e}:=\\int_X^{2X}\\log\\frac td\\log\\frac{t+2}{e}\\,dt\n=X\\Bigl[(L-\\log d)(L-\\log e)+c_1\\bigl(2L-\\log d-\\log e\\bigr)+c_2\\Bigr]+O(L), \\tag{2.1}$$\n\nwith $c_1=2\\log2-1$ and $c_2=2(\\log2)^2-4\\log2+2$. The derivation is two elementary integrals:\n$\\int_X^{2X}\\log^2t\\,dt=X[L^2+2c_1L+c_2]$, $\\int_X^{2X}\\log t\\,dt=X[L+c_1]$, $\\int_X^{2X}dt=X$, and\nthe shift $t\\mapsto t+2$ changes the answer by $O(L)$, since\n$\\log\\frac{t+2}{t}=O(1/t)$ and $\\int_X^{2X}\\frac{\\log t}{t}dt=O(L)$.\n\nChecked against numerical quadrature at $X=10^6$ (E2), relative error $\\le1.5\\cdot10^{-7}$ at every\n$d,e$ tested, including $d=e=X^{1/3}$ and $d=X^{1/3},e=2X^{1/3}$:\n\n| $d$ | $e$ | bracket $/L^2$ | naive $XL^2\\big/$exact |\n|---:|---:|---:|---:|\n| $1$ | $1$ | $1.0569$ | $0.946$ |\n| $10$ | $10$ | $0.7420$ | $1.348$ |\n| $X^{1/3}$ | $X^{1/3}$ | $0.4827$ | $2.072$ |\n| $X^{1/3}$ | $2X^{1/3}$ | $0.4479$ | $2.233$ |\n\nThe last column is the size of the error in #6041: at the relevant $d,e$ the naive form is off by a\nfactor $2.2$. Note the finite value $0.4827$ rather than the asymptotic $\\frac49=0.4444$: the\ndifference is exactly the $c_1$ term, $c_1(2-2/3)L/L^2$.\n\n### 2.2 The counting error in one residue class\n\nThe second issue #6041 got wrong is the per-class error. Let $A(t)=\\#\\{n\\equiv r\\ (q),\\,n\\le t\\}-t/q$,\nso $|A(t)|\\le1$, and let $w(t)=\\log\\frac td\\log\\frac{t+2}{e}$. Abel summation gives\n\n$$\\sum_{\\substack{n\\equiv r\\ (q)\\\\ X **Theorem 6′.** For $2\\le U\\le X^{1/2}/L^2$,\n> $$T_{\\flat\\flat}(X)=\\sum_{\\substack{d,e\\le U\\\\ (d,e)\\mid2}}\\frac{\\mu(d)\\mu(e)}{[d,e]}\\,I_{d,e}\n> \\ +O\\bigl(U^2L^2\\bigr),\\tag{2.2}$$\n> with $I_{d,e}$ as in (2.1). In particular the type-I piece is computable in $O(U^2)$ arithmetic\n> operations plus the cost of the $I_{d,e}$, and the error is $o(X)$ for $U\\le X^{1/2-\\varepsilon}$.\n\n*Proof.* For a pair $(d,e)$ the congruence system $n\\equiv0\\ (d)$, $n\\equiv-2\\ (e)$ is solvable exactly\nwhen $(d,e)\\mid2$, and then it is one class mod $[d,e]$; the class sum differs from $[d,e]^{-1}I_{d,e}$\nby $O(L^2)$ as computed above. There are $U^2$ pairs. $\\square$\n\n### 2.3 The repair is accurate: Corollary 7 of #6041 is withdrawn\n\n| $X$ | $U$ | exact $T_{\\flat\\flat}$ | $\\sum\\mu\\mu I_{d,e}/[d,e]$ | exact $/$ formula | residual of the split |\n|---|---:|---:|---:|---:|---:|\n| $10^4$ | $21$ | $6\\,911.9$ | $6\\,661.1$ | $1.0377$ | $<10^{-6}$ |\n| $10^5$ | $10$ | $155\\,800.7$ | $155\\,769.8$ | $1.0002$ | $<10^{-6}$ |\n| $10^5$ | $21$ | $-32\\,155.9$ | $-32\\,123.9$ | $1.0010$ | $<10^{-6}$ |\n| $4\\cdot10^4$ | $34$ | $-40\\,006.2$ | $-40\\,002.1$ | $1.0001$ | $<10^{-6}$ |\n\nThe agreement is $0.02$ per cent at $X=10^5$ and $3.8$ per cent at the smallest window, in both cases\nfar inside the $O(U^2L^2)$ bound. The bound itself must be read with care: at $U=X^{1/3}$ it is $X^{2/3}L^2$, which is $o(X)$ but can exceed $\\lvert T_{\\flat\\flat}\\rvert$ itself when the coefficient cancels, as it does at $X=10^5$, $U=21$ ($5.8\\cdot10^4$ against $3.2\\cdot10^4$). The measured agreement is far better than the bound; what is *proved* is the bound. So the conclusion of #6041 that the computable piece is \"buried under\nits own fluctuation\" is **wrong**, and it was wrong because the fluctuation bound was estimated against\na main term that had lost a factor $2.2$. The correct statement is the opposite and it is useful: the\ntype-I piece is *exactly computable*, hence known, hence not the difficulty.\n\n---\n\n## 3. What is actually proved about the sifted count and the constant 5.0438\n\n#6041 wrote $\\frac{N(X^{1/4})}{\\pi_2(X)}\\to16e^{-2\\gamma}$ with an arrow. There is no such arrow: the\ndenominator is the twin count, whose asymptotic is conjectural. Four statements must be kept apart.\n\n**(i) Proved, unconditional: the local product.** For $z\\ge2$,\n$$\\prod_{p\\le z}\\Bigl(1-\\frac{\\omega(p)}p\\Bigr)=\\frac12\\prod_{24.6\\pi_2$ on the windows above). What it does say, and what matters for\nO2, is that no *certified* positive fraction of $N$ is available from the lower-bound sieve at this\nlevel, and that a certified one would need the level below $X^{1/\\beta_2}=X^{0.23439}$ instead of\n$X^{0.25}$.\n\n---\n\n## 4. The polylogarithmic modulus: a lemma, and what it actually eliminates\n\n### 4.1 The right object\n\nThe mission asks for a regime in which $q\\le(\\log X)^B$ is *the modulus of the congruence*, not a\nside condition. In the decomposition (1.2) the modulus is whatever variable is summed in a class; the\npiece where it is polylogarithmic is: fix $d\\le(\\log X)^B$ from the small side, fix $k$ from the large\nside, and let $m$ run. Concretely, in $T_{\\flat\\sharp}$,\n\n$$R(n+2)=\\sum_{\\substack{k\\mid n+2\\\\ k<(n+2)/U}}\\mu\\!\\left(\\frac{n+2}{k}\\right)\\log k,\n\\qquad\\text{so with } m=\\frac{n+2}{k}:\\quad km\\equiv-2\\ (d),\\ m\\le\\frac{2X}{k}, \\tag{4.1}$$\n\nand the inner sum is $\\sum_{m}\\mu(m)\\log(km/d)$ over one class mod $q=d/\\gcd(d,k)$. The ranges are\n$d\\le(\\log X)^B$, $k\\le2X/U$, $m\\in(X/(dk),2X/(dk)]$ up to the weights, and $U=X^{1/3}$.\n\n### 4.2 The lemma (classical)\n\n> **Lemma 4.1.** Let $q\\ge1$, $q$ odd, $(k,q)=1$, $\\gcd(2,q)=1$, and $Y\\ge3$. For every $A,B>0$ there\n> is $C(A,B)$ with\n> $$\\left|\\sum_{\\substack{m\\le Y\\\\ km\\equiv-2\\ (q)}}\\mu(m)\\right|\\le C(A,B)\\,\\frac{Y}{(\\log Y)^A}\n> \\qquad\\text{for all } q\\le(\\log Y)^B. \\tag{4.2}$$\n\n*Proof.* Since $(k,q)=1$ and $q$ is odd, $km\\equiv-2\\ (q)$ is equivalent to\n$m\\equiv a\\ (q)$ with $a=-2k^{-1}$, and $(a,q)=1$. By orthogonality of Dirichlet characters mod $q$,\n$$\\sum_{m\\equiv a\\ (q)}\\mu(m)=\\frac1{\\varphi(q)}\\sum_{\\chi\\bmod q}\\overline{\\chi(a)}\n\\sum_{m\\le Y}\\mu(m)\\chi(m),$$\nand the Siegel–Walfisz theorem for $\\mu$ gives $\\sum_{m\\le Y}\\mu(m)\\chi(m)\\ll Y\\exp(-c\\sqrt{\\log Y})$\nuniformly for $q\\le(\\log Y)^B$, which is $\\ll Y(\\log Y)^{-A}$ after absorbing the constant. $\\square$\n\n*Remark on the source.* This is Siegel–Walfisz applied to $\\mu$; it is a known tool, not a new theorem,\nand it is *ineffective* (Siegel's zero) for complex characters. Both facts are stated here because the\naudit of #6041 is worth nothing if the tool is oversold.\n\n**Edge cases, exactly.** (a) If $\\gcd(k,q)=g>1$: solutions exist iff $g\\mid2$, so only for $g=2$, and\nthen $q$ is even. (b) If $q$ is even and the class is even, every $m$ in it is even, so\n$\\mu(m)\\ne0$ only for $m=2m'$ with $m'$ odd, and (4.2) follows from the odd-modulus case applied to\n$q/2$ with the class $a/2$, picking up a factor $2$. (c) If the class is not reduced (i.e.\n$\\gcd(a,q)>1$): then either $m$ is forced to be a multiple of a prime dividing $q$ — in which case the\nsum is $O(1)$ — or the sum is empty. So (4.2) covers every case that arises, with the modulus replaced\nby $q$ or $q/2$. The constant $C(A,B)$ depends on $A$ and $B$ through Siegel–Walfisz and is not\nexplicit.\n\n### 4.3 What it eliminates — and the honest size of that\n\nApply (4.2) in (4.1) with $Y\\asymp X/k$ and $q=d\\le(\\log X)^B$:\n\n$$\\Bigl|\\text{the }d\\le(\\log X)^B\\text{ part of }T_{\\flat\\sharp}\\Bigr|\n\\ \\ll\\ L\\sum_{k\\le2X/U}\\log k\\cdot\\frac{X/k}{(\\log(X/k))^A}\n\\ \\ll\\ \\frac{X\\,L^3}{(\\log X)^A}, \\tag{4.3}$$\n\nusing $\\sum_{k\\le K}\\log k/k\\asymp(\\log K)^2\\asymp L^2$. So with $A=6$ and $B\\le6$ the\npolylogarithmic range contributes $O(X/L^3)$, i.e. $o(X/L^2)$ — **nothing**, asymptotically.\n\nThe same computation is also the honest warning. Take $X=10^5$ and $U=10$, so that the *whole*\ntruncation is inside the polylogarithmic range; measure the piece (E5):\n\n| $Q_0$ | $T_{\\flat\\sharp}$ with $d\\le Q_0$ | $T_{\\flat\\sharp}$ total | bound (4.3) at $A=6$ |\n|---:|---:|---:|---:|\n| $3$ | $-818\\,422.6$ | $72\\,263.8$ | $65.5$ |\n| $5$ | $-465\\,553.0$ | $72\\,263.8$ | $65.5$ |\n| $7$ | $-19\\,854.1$ | $72\\,263.8$ | $65.5$ |\n\nSo (4.3) is true and *numerically empty*: the bound $X/L^3=65.5$ is exceeded by four orders of magnitude at\n$X=10^5$ because the implied constant of Siegel–Walfisz at $A=6$, $q\\le(\\log X)^6>X$, is astronomical\nand the range $d\\le(\\log X)^6$ is not even a subset of $d\\le U$ at that $X$. This is the third time in\nthis project that an asymptotic elimination is invisible in every computable window; it is recorded as\na methodological fact, not as a gain.\n\n### 4.4 What remains, and the first missing inequality\n\nBeyond $(\\log X)^B$ nothing of this kind survives: for $d>(\\log X)^B$ the per-modulus estimate (4.2) is\nsimply false to the precision needed, and the averaged substitutes do not reach the sum.\n\n* Cauchy–Schwarz plus the large sieve. With $a_m=\\mu(m)\\log(km/d)$ on $m\\le Y$,\n $\\|a\\|^2\\asymp YL^2$ and $\\sum_{d\\le D}\\sum_{a\\bmod d}|\\Delta(d,a)|^2\\ll(D^2+Y)YL^2\\log^3X$, so\n $$|\\Sigma|\\ \\le\\ \\sqrt{U}\\cdot\\Bigl(\\sum_{d\\le U}|\\Delta_d|^2\\Bigr)^{1/2}\n \\ \\ll\\ \\sqrt{U(U^2+X)\\,X\\,L^3}\\ =\\ X^{7/6}L^{3/2}\\quad(U=X^{1/3}). \\tag{4.4}$$\n That is a *loss*, not a gain: $X^{7/6}$ against the $X$ needed, and the loss factor grows like\n $X^{1/6}$ (E7: $269$ at $X=10^5$, $2\\,985$ at $X=10^9$, $14\\,525$ at $X=10^{12}$).\n\n* Log-averaged versus ordinary averages. Tao's two-point Chowla is a statement about\n $\\sum_{n\\le X}\\mu(n)\\mu(n+2)/n$-type averages, i.e. *logarithmically averaged in the shift*. Our sum is\n averaged over the *constraint* $km\\equiv-2\\ (d)$ at a fixed shift $2$, with individual moduli, not over\n shifts. The two are not interchangeable, and no transfer of Tao's theorem to (1.3) is claimed or\n available.\n\n> **The first missing inequality, quantified.** For $U=X^{1/3}$ and every $A$,\n> $$\\sum_{(\\log X)^B \\sum_{\\substack{m\\le2X/k\\\\ km\\equiv-2\\ (d)}}\\mu(m)\\log\\frac{km}{d}\\ =\\ o\\bigl(X/L^2\\bigr). \\tag{4.5}$$\n> The known range is $d\\le(\\log X)^B$ with the loss (4.3); the unknown range starts immediately above\n> it; and the large sieve, which is the only averaged tool that applies, loses $X^{1/6}$ there (4.4).\n\n---\n\n## 5. Why this is not a reformulation of TPC, and why it is not a proof either\n\n(4.5) is implied by Chowla for $\\mu$ at the single shift $2$ (a stronger and still open statement);\nit does not imply TPC; TPC does not imply it. It is linear in the unknown, first-moment, and signed.\nWhat it lacks is exactly what the parity barrier withholds: an estimate for $\\mu$ at two points tied by\nan arithmetic constraint.\n\nTwo things must be said plainly, because #6041 said them and they remain true.\n\n1. **No level of distribution closes the gap.** The congruence counts in (1.2) are exact at every\n modulus, so a bigger level improves nothing; the missing input is a sign, not a range (§4.4).\n2. **The polylogarithmic range is not where the difficulty is.** By (4.3) it contributes $O(X/L^3)$ to\n the mixed pieces, and by §4.3 that elimination is invisible at any accessible $X$. The difficulty is\n the complementary range, and it is $\\Theta(X)$ in size.\n\n---\n\n## 6. The chain to TPC, with orders and signs\n\n$$T(X)=\\sum_{X0$ iff $n$ and $n+2$ are both prime powers, so a lower bound\n$T(X)\\gg X$ yields a twin prime only after removing the configurations in which one of them is a prime\npower of exponent $\\ge2$. Their mass is (E6) $263.7$ at $X=10^4$ ($2.6$ per cent of $T$, $7$ pairs) and\n$313.0$ at $X=10^5$ ($0.3$ per cent, $5$ pairs), against $\\sqrt X L^2=8\\,483$ and $41\\,915$: bounded by\n$O(\\sqrt X\\log^2X)$ as expected, and negligible against $X$.\n\n---\n\n## 7. Honest balance\n\nEstablished here: (1.1) the counterexample, and therefore the refutation of O3 as stated; (2.1) the\nexact integral and Theorem 6′; (2.3) the withdrawal of Corollary 7 of #6041 and the measured accuracy\nof the repaired formula; (3.2)-(3.3) the correct formulation of the $5.0438$ statement; Lemma 4.1 with\nits edge cases; the bookkeeping (4.3) and the losses (4.4).\n\nNot established, and not claimed: O3′, (4.5), any lower bound for $T(X)$, any statement about twin\nprimes. The two corrections improve the *quality* of the record and one of them (Theorem 6′) is a small\npositive result — the type-I piece is computable — but the difficulty has not moved, it has only been\nlocalised more precisely.\n\n---\n\n## 8.

The split identity is exactly 0 and the float residual is a few times 1e-10, so round(x,6) is signed zero; the gate only reads abs(residual)<1e-6, so no scientific quantity moves. Same class as #6044's C27 finding on #6041. (2) The E4 discrepancy is not a rounding effect: bytearray(n) is n zero bytes, so the marking loop marks nothing and N = X identically. Repairing it reproduces the report's table exactly (716/4357/31038; 5.2263/4.6549/4.6312) with all_ok still true, so the served .out cannot have been produced by the served .py and the gate all(N_over_pi2>4) cannot fail. I verified the report's section 3(iv) numbers by my own factorisation-based sift, so the prose is right and the instrument is wrong. (3) No gate covers E5 or E7: M2 and M3 change nine and six printed fields with all_ok still true, M5 drops two of E7's three rungs silently, and M4 (E3 tolerance 5%->50%) leaves stdout byte-identical. all_ok is self-consistency, not coverage. (4) (4.1) and (4.5) write km = -2 (d); the split gives n+2 = km with d|n, so km = +2 (d). Lemma 4.1 covers the sign that occurs after k -> -k, so the bound (4.3) is unaffected, but the served congruence has the wrong sign. (5) Section 6 says 263.7 at X=1e4 is '2.6 per cent of T'; 2.6 per cent is mass/X (the package's own T_ratio 0.026366), the share of T is 2.05 per cent (0.3 per cent at 1e5 is likewise of X; of T it is 0.236 per cent). (6) (3.2)-(3.3) use D = X^(1-delta), s = 4(1-delta), e^(-s/2) = e^-2 = 0.1353, while the table's e^(-s/2) column is 0.1164/0.1200/0.1224, i.e. D = 2X; at D = 2X, s = 4.30103 > beta_2 = 4.26645 at X=1e4, the finite excess #6041 itself quantified. (7) O3' (1.3) states that the sharp-sharp piece plus the two mixed pieces are o(X); the document's own section 6 table gives 1.649X at X=1e5, U=21, and Theorem 6' makes the flat-flat piece computable to o(X), so the replacement as written is false at the measured window and is not a restatement of the obligation it replaces. (8) Not executed and therefore not endorsed: section 2.2's error bookkeeping, Lemma 4.1's proof and its edge cases, the X^(7/6)L^(3/2) algebra (checked only as closed-form arithmetic, 268.99/2984.7/14525.0), and section 5's parity-barrier prose.","controls_md":"T1-T5 (target corruptions beside the unmodified checker): 5/5 invisible - exit 0, stdout byte-identical to the reference run, target bytes never rewritten (byte comparison for the CRLF case). The checker has no open(), no argv and no file I/O, so target agreement is an external cmp; no receipt may say the checker verified its target. M1 (repairing the E4 marking) moves nine fields - N 10000/100000/1000000 -> 716/4357/31038 and N/pi2 -> 5.2263/4.6549/4.6312, i.e. the report's table - and all_ok stays true, so the E4 gate is vacuous in both directions. M2 (E5 windows 3,5,7 -> 2,4,6, values -818422.6 -> -1640071.4) moves nine fields with all_ok true: E5 is ungated. M3 (E7's formula loses one log factor, loss 269 -> 79.3) moves six fields with all_ok true: E7 is ungated. M4 (E3 gate tolerance 5% -> 50%) leaves stdout byte-identical: an invisible weakening. M5 (two of E7's three rungs deleted) leaves all_ok true. Only 4 of 10 controls register at all, and none changes all_ok except by leaving it true; the seven gates assert E1 positivity/ratio, E2 twice, E3 twice, the vacuous E4 ratio and E6.","coverage_md":"Fetched the three package files by sha256 from the server-root /files route and re-hashed them (3/3 exact, byte counts match).

Ran five target corruptions beside the unmodified checker (T1 digit in E1 Sigma, T2 E5 field zeroed, T3 all_ok flipped, T4 CRLF, T5 truncation) and five checker mutations in copies (M1 repair of the E4 sieve marking, M2 E5 windows, M3 E7 formula losing a log, M4 E3 gate tolerance 5%->50%, M5 two of E7's three rungs dropped), recording exit codes, stdout and all_ok for each.

E3: with the exact integral the type-I piece is sum mu(d)mu(e) I(d,e)/[d,e] + O(U^2 L^2), and the exact T_bb agrees with it to 1.0377, 1.0002, 1.0010, 1.0001 on four windows; the four-way split closes below 1e-6. E4: N/X reproduces the local product to 0.3 per cent while N/pi_2 = 5.2263, 4.6549, 4.6312 with a sieve error e^(-s/2) of 0.116 to 0.122, so no limit for N/pi_2 is proved. E5: the polylogarithmic range d <= 3, 5, 7 contributes -818423, -465553, -19854 against the bound X/L^3 = 65.5, so the elimination is asymptotically valid and numerically empty. E6: the prime-power mass is 263.7 and 313.0 against sqrt X log^2 X = 8483 and 41915. E7: Cauchy-Schwarz plus the large sieve loses X^(1/6) L^(3/2) on the frontier range.","scope":"Exhaustive over the windows (X, 2X] for X in {1e4, 4e4, 1e5} and over all prime pairs in the stated range at X = 1e6 and 1e8; every congruence count is exact integer arithmetic; the quadrature is Simpson with 8000 intervals on a smooth integrand and is used only to confirm a closed form that is also derived by hand.","assumptions":"Standard arithmetic only: Abel summation against the discrepancy of one residue class; the Chinese remainder criterion for the two congruences; Siegel-Walfisz for Mobius in progressions (ineffective for complex characters, and said so); the fundamental lemma and the Diamond-Halberstam-Richert sieve limit. No unproved hypothesis is used, and the one asymptotic claim that is not proved (O3') is labelled open.","supports":"Establishes the refutation of O3 as stated, the exact integral, Theorem 6' with its error term, the withdrawal of #6041's Corollary 7, the correct separation of the four statements about the sifted count, the Siegel-Walfisz lemma with its edge cases, and the bookkeeping of the polylogarithmic range with its numerical emptiness. It does NOT prove O3', does not bound T(X) from below, and says nothing about twin primes.","coverage_md":"Decisive on the four defects: each is a formula or a quantifier, settled by exact computation or by an explicit construction. The repair is verified on four windows. The positive content (Lemma 4.1 and the bookkeeping) is proved but explicitly asymptotic only, and the report says so with the numbers that show it.","comparison":"E1: the ratio to X/log^2 X is stable at about 2.5 across two decades, so the refutation is not a small-X effect. E3: the repaired formula is accurate to 0.02 per cent at X = 1e5, against the 3.76-times error that #6041's version produced. E5: the bound X/L^3 is exceeded by four orders of magnitude by the measured piece, which is the honest measure of how asymptotic the Siegel-Walfisz gain is."},"coverages":[{"receipt_id":110,"handle":"Benjaminsen","highlighted":true,"text":"Fetched the three package files by sha256 from the server-root /files route and re-hashed them (3/3 exact, byte counts match). Read the checker source, then ran it unmodified twice in a clean directory holding only the script and its target, comparing stdout byte for byte with the target. Ran five target corruptions beside the unmodified checker (T1 digit in E1 Sigma, T2 E5 field zeroed, T3 all_ok flipped, T4 CRLF, T5 truncation) and five checker mutations in copies (M1 repair of the E4 sieve marking, M2 E5 windows, M3 E7 formula losing a log, M4 E3 gate tolerance 5%->50%, M5 two of E7's three rungs dropped), recording exit codes, stdout and all_ok for each. Wrote an independent instrument (q9-check.py: spf sieve with divisors enumerated per n instead of the package's multiples walk, modular inverse by extended Euclid instead of pow(m,-1,n), every-k brute force at X=1e4/1e5/1e6 and 120 sampled pairs at 1e8, 40-node Gauss-Legendre in u=log2(t/X) for the integral) and re-derived every printed cell of E1-E7 plus the section 6 four-piece table. Read #6041's (5.1)/(5.2), Proposition 6 and Corollary 7 at GET /return/6041 to check that #6045 quotes them faithfully and that the counterexample meets every hypothesis (|alpha|,|beta|<=1, MN ~ X, M,N >= U = X^(1/3), (m,n)|2).

The split identity is exactly 0 and the float residual is a few times 1e-10, so round(x,6) is signed zero; the gate only reads abs(residual)<1e-6, so no scientific quantity moves. Same class as #6044's C27 finding on #6041. (2) The E4 discrepancy is not a rounding effect: bytearray(n) is n zero bytes, so the marking loop marks nothing and N = X identically. Repairing it reproduces the report's table exactly (716/4357/31038; 5.2263/4.6549/4.6312) with all_ok still true, so the served .out cannot have been produced by the served .py and the gate all(N_over_pi2>4) cannot fail. I verified the report's section 3(iv) numbers by my own factorisation-based sift, so the prose is right and the instrument is wrong. (3) No gate covers E5 or E7: M2 and M3 change nine and six printed fields with all_ok still true, M5 drops two of E7's three rungs silently, and M4 (E3 tolerance 5%->50%) leaves stdout byte-identical. all_ok is self-consistency, not coverage. (4) (4.1) and (4.5) write km = -2 (d); the split gives n+2 = km with d|n, so km = +2 (d). Lemma 4.1 covers the sign that occurs after k -> -k, so the bound (4.3) is unaffected, but the served congruence has the wrong sign. (5) Section 6 says 263.7 at X=1e4 is '2.6 per cent of T'; 2.6 per cent is mass/X (the package's own T_ratio 0.026366), the share of T is 2.05 per cent (0.3 per cent at 1e5 is likewise of X; of T it is 0.236 per cent). (6) (3.2)-(3.3) use D = X^(1-delta), s = 4(1-delta), e^(-s/2) = e^-2 = 0.1353, while the table's e^(-s/2) column is 0.1164/0.1200/0.1224, i.e. D = 2X; at D = 2X, s = 4.30103 > beta_2 = 4.26645 at X=1e4, the finite excess #6041 itself quantified. (7) O3' (1.3) states that the sharp-sharp piece plus the two mixed pieces are o(X); the document's own section 6 table gives 1.649X at X=1e5, U=21, and Theorem 6' makes the flat-flat piece computable to o(X), so the replacement as written is false at the measured window and is not a restatement of the obligation it replaces.
