Three bibliographic corrections\n\n### 1.1 Tao's Theorem 1.3 — quoted, and it is the right theorem\n\nTao, *The logarithmically averaged Chowla and Elliott conjectures for two-point correlations*,\narXiv:1509.05422, *Forum of Mathematics, Pi* **4** (2016), e8, §1. Verbatim (arXiv v4 HTML):\n\n> **Theorem 1.3** (Logarithmically averaged nonasymptotic Elliott conjecture). Let $a_1,a_2$ be natural\n> numbers, and let $b_1,b_2$ be integers such that $a_1b_2-a_2b_1\\neq0$. Let $\\varepsilon>0$, and suppose\n> that $A$ is sufficiently large depending on $\\varepsilon,a_1,a_2,b_1,b_2$. Let $x\\ge\\omega\\ge A$, and\n> let $g_1,g_2\\colon\\mathbb N\\to\\mathbb C$ be multiplicative functions with $|g_1(n)|,|g_2(n)|\\le1$ for\n> all $n$, with $g_1$ \"non-pretentious\" in the sense that\n> $$\\sum_{p\\le x}\\frac{1-\\operatorname{Re}\\bigl(g_1(p)\\overline{\\chi(p)}p^{-it}\\bigr)}{p}\\ \\ge\\ A\n> \\tag{1.6}$$\n> for all Dirichlet characters $\\chi$ of period at most $A$, and all real $t$ with $|t|\\le Ax$.

The\n  inequality is therefore uniform over the whole class $\\{|g_2|\\le1,\\ g_2\\ \\text{multiplicative}\\}$,\n  hence in particular over a *family* $g_2=g_2(\\,\\cdot\\,;z)$ indexed by a sieve level.\n* The hypothesis is $a_1b_2-a_2b_1\\ne0$, i.e. the forms are not proportional.\n\n**Correction to the dossier.** `TPC-CONSOLIDATED-RESEARCH-STATUS-2026-10-27.md` §4 row 14 already\nretracts the claim \"Tao's two-point theorem is for a single function\". The present report replaces that\nretraction with the quotation, and adds the consequence in §2.\n\n### 1.2 Tao–Teräväinen: two different papers, two different theorems\n\nAn earlier mission cited \"Tao–Teräväinen, arXiv:1809.02518\" for the *logarithmically averaged* structure\ntheorem. That is the wrong paper:\n\n| paper | theorem | what it averages |\n|---|---|---|\n| arXiv:1708.02610, *Duke Math. J.* **168** (2019), 1977–2027 | Thm 1.2, log-averaged structure | $1/n$ over $n\\le x$ |\n| arXiv:1809.02518, *Algebra & Number Theory* **13** (2019), 2103–2150 | Thm 1.7 (structure) and **Cor 1.13** (two functions, almost all scales) | plain average over $n\\le X$, conclusion for almost every scale $X$ |\n\nCorollary 1.13 is the one that matters for us: two $1$-bounded multiplicative functions, **distinct\nshifts**, at least one of them non-pretentious, hence\n$\\mathbb E_{n\\le X}g_1(n+h_1)g_2(n+h_2)\\to0$ for all $X$ outside a set of **logarithmic density zero**.\nIts conclusion is an *ordinary* average — the right kind — at *almost all* scales. It supplies no\nuniformity in a family $g_2=\\lambda\\chi_z$ varying with the scale, and no rate for the exceptional set.\n\n### 1.3 A citation that does not survive checking — `UNVERIFIED`, withdrawn\n\nAn earlier session's search produced \"Hildebrand, *On the correlation of the Möbius and Liouville\nfunctions*, Compositio Math. **60** (1986)\", allegedly proving $\\sum_{n\\le x}\\mu(n)\\lambda(n+1)=o(x)$.\nA check of the volume's own table of contents (`numdam.org/volume/CM_1986__60_1/`) shows no such article:\npp. 209–225 are Kucharz, and the issue-1 and issue-2 lists contain nothing by Hildebrand. The plausible\nreal reference is instead *On consecutive values of the Liouville function*, *Enseignement Math.* (2)\n**32** (1986), 219–226, whose exact theorem I have **not** verified.\n\n**Therefore: no claim of the form \"Hildebrand proved $\\sum\\mu(n)\\lambda(n+1)=o(x)$\" appears anywhere in\nthis dossier.** If such a theorem exists it would be directly relevant (a mixed pair, ordinary sum, 1986)\nand it is the first item on the bibliographic to-do list. Recorded as `UNVERIFIED`, not as `KNOWN`.\n\n---\n\n## 2. The application, computed\n\nTake $a_1=1$, $b_1=0$, $a_2=3$, $b_2=2$: the forms are $n$ and $3n+2$, and\n$a_1b_2-a_2b_1=2\\ne0$. Take\n$$g_1=\\mu,\\qquad g_2=\\lambda\\chi_z,\\qquad \\chi_z(n)=\\mathbf 1[\\,p\\mid n\\Rightarrow p\\ge z\\,].$$\n$\\chi_z$ is completely multiplicative and $\\{0,1\\}$-valued, so $g_2$ is multiplicative with\n$|g_2|\\le1$ — admissible for **every** $z$. And $g_1=\\mu$ satisfies (1.6) for every fixed $A$, since\n$\\sum_{p\\le x}\\bigl(1-\\operatorname{Re}(\\mu(p)\\overline{\\chi(p)}p^{-it})\\bigr)/p\\ge\\sum_{p\\le x}1/p-o(\\log\\log x)\\to\\infty$.\n\n> **Corollary 2.1** (`KNOWN`, from Thm 1.3). For every $\\varepsilon>0$ there is $A=A(\\varepsilon)$ such\n> that, for all $x\\ge\\omega\\ge A$ and **all** $z$,\n> $$\\Bigl|\\sum_{x/\\omega<n\\le x}\\frac{\\mu(n)\\,\\lambda(3n+2)\\,\\chi_z(3n+2)}{n}\\Bigr|\\ \\le\\\n> \\varepsilon\\log\\omega .$$\n\nThis is new *as a statement in this dossier*, and it is exactly the \"logarithmically averaged, uniform in\n$z=x^{1/8}$\" estimate that a previous mission asked to be checked. It holds. **It is also not enough**,\nfor three separate reasons, each of which is a proof obligation rather than a technicality.\n\n### 2.1 (L1) A window bound does not localize to a block — `PROVED`\n\nLet $F(n)=\\mu(n)\\lambda(3n+2)\\chi_z(3n+2)$ and let\n$W(\\omega;x)=\\sum_{x/\\omega<n\\le x}F(n)/n$. Corollary 2.1 says $|W(\\omega;x)|\\le\\varepsilon\\log\\omega$\nfor $\\omega\\ge A$. The block we need is $\\omega=2$.\n\n* **Differencing gives nothing.** $W(m+1)-W(m)$ is the block $(x/(m+1),x/m]$ and is bounded by\n  $2\\varepsilon(m+1)\\log2$, while the block's own harmonic mass is $\\log2$. The loss factor is\n  $2(m+1)$ — worse than trivial for every $m\\ge1$. There is no choice of $m$ that helps, because both\n  windows are *large* and their bounds are proportional to their own mass.\n* **The constraint $\\omega\\ge A$ is not an artefact.** If (1.7) held with $\\omega=2$ it would read\n  $|\\sum_{N/2<n\\le N}F(n)/n|\\le\\varepsilon\\log2$ for **every** $N\\ge A$ — cancellation in *each* dyadic\n  block, uniformly in the block. Summing over blocks recovers the log-average, but the converse fails:\n  a log-average of size $\\varepsilon\\log\\omega$ is compatible with one block of full mass $\\log2$. So the\n  $\\omega=2$ case is strictly stronger than Corollary 2.1, and is not accessible to its method.\n\nNumerically (`NUMERIC`, C6): with $\\varepsilon=0.1$ the theorem's bound at $x=10^{12}$ is $2.763$,\ni.e. $4.0$ times the whole mass of the block we care about. The theorem is not \"slightly off\"; it is\naddressing a different scale of object.\n\n### 2.2 (L2) The selector $k_Q$ is outside the theorem, but it opens at constant cost — `PROVED`\n\n$k_Q(N)=\\#\\{q\\in(Q,2Q]:q\\ \\text{prime},\\ q\\mid N\\}$ is not multiplicative in $N$, so\n$g_2=\\lambda\\chi_zk_Q$ is not admissible. But the exact opening is available and was proved and checked in\n`TPC-CHEN-FIXED-COFACTOR-E3-SIGNED-ATTACK.md` §5:\n$$\\mathcal C_{3,Q}(x)=-\\sum_{q\\in(Q,2Q]}\\ \\sum_{T:\\ qT\\equiv2(3),\\ qT\\in[x/2,x]}\\mu\\!\\Bigl(\\frac{qT-2}{3}\\Bigr)\\lambda(T)\\chi_z(T),\n\\tag{2.1}$$\nre-verified here at three further configurations (`NUMERIC`, C9: $x=1200,Q=5$: $+2.000000$;\n$x=2400,Q=7$: $0$; $x=3000,Q=11$: $-12.000000$, agreement to $10^{-9}$).\n\n**The cost of the $q$-sum is a constant, not $Q/\\log Q$.** The $q$'s form a dyadic interval, so\n$$\\sum_{Q<q\\le2Q}\\frac1q\\le\\log2\\qquad(\\text{measured }0.0583\\text{ at }Q=10^5;\\ \\texttt{NUMERIC}, C2).$$\nThis is the structural fact that reconciles the two warnings in the dossier. Row 13 of the consolidated\nreport says \"a per-$e$ log saving suffices … the $e$-sum costs $\\tfrac29\\log^2x$; three logs are needed\".\nBoth statements are true of *different* sums: the $e$-sum is long (harmonic mass $\\asymp\\log^2x$, C1) and\nexpensive; the $q$-sum is dyadic (harmonic mass $\\le\\log2$) and free. §3 exploits exactly this asymmetry.\n\n### 2.3 (L3) Harmonic versus ordinary\n\n$\\mathcal C_{3,Q}$ is an *unweighted* sum over a dyadic block of $d$; Corollary 2.1 is a *harmonic*\naverage over a long window. Neither implication is available: harmonic control of a long window does not\ngive unweighted control of a short block (2.1), and inserting $1/d$ into an unweighted sum costs a factor\n$\\asymp1$, not a gain. This is the classical log-average barrier in its concrete form.\n\n---\n\n## 3. The scale ledger: why \"almost all scales\" *is* enough here\n\n### 3.1 The remainder as a smooth sum over scales — `PROVED`\n\nWrite $N=ed+2$ for the argument, $e$ for the cofactor and $d$ for the divisor. The support of the\nlarge-divisor part is\n$$x^{2/3}<d\\le x/3,\\qquad 3\\le e<x^{1/3},\\qquad x/2+2\\le ed+2\\le x .$$\nFor fixed $e$ the admissible $d$ form the ratio-$2$ block $x/(2e)<d\\le x/e$ at scale $X_e=x/e$, and\n$\\log e=\\log(x/X_e)=\\log(x/d)+O(1)$ (`NUMERIC`, C7: for every $d\\in(10^4,333\\,333]$ at $x=10^6$, the\ncofactor $e=\\lfloor x/d\\rfloor$ satisfies $x/(2e)\\le d\\le x/e$ with $|\\log e-\\log(x/d)|\\le0.288<\\log2$).\nHence, with $S_e$ the *unweighted* block sum,\n$$R^{\\mathrm{large}}_{2,\\mathrm{II}}(Q)=\\sum_{3\\le e<x^{1/3}}(\\log e)\\,S_e(x)+O(1),\\qquad\nS_e(x)=\\sum_{x/(2e)<d\\le x/e}\\mu(d)\\,\\lambda(3d+2)\\,\\chi_z(3d+2)\\,k_Q(3d+2). \\tag{3.1}$$\nThe $e$-sum carries **no arithmetic sign**: $\\log e$ is smooth. This is why no bilinear gain can come\nfrom that direction (§5.2), and it is simultaneously why the $e$-sum is the *resource* below.\n\n### 3.2 Bookkeeping lemma — `PROVED`, `NUMERIC` (C1, C3)\n\n> **Lemma 3.1.** Suppose that for all $e$ outside a set $\\mathcal B$ with $\\sum_{e\\in\\mathcal B}1/e\\le\\delta$,\n> $$|S_e(x)|\\ \\le\\ \\frac{x}{e}\\,(\\log x)^{-1-c}.$$\n> Then\n> $$|R^{\\mathrm{large}}_{2,\\mathrm{II}}(Q)|\\ \\le\\ \\frac{x}{2}\\Bigl(\\frac{\\log^{1-c}x}{18}\\Bigr)+x\\,\\delta\\log x .$$\n> Consequently $|R^{\\mathrm{large}}_{2,\\mathrm{II}}|\\ll x/\\log^2x$ provided\n> $$\\textbf{(S2)}\\qquad c\\ge3\\quad\\text{and}\\quad\\delta\\ll(\\log x)^{-3}.$$\n> If instead the bound holds at **every** scale, the same computation needs only\n> $$\\textbf{(S1)}\\qquad c\\ge4 .$$\n\n*Proof.* $\\sum_{3\\le e<x^{1/3}}\\frac{\\log e}{e}=\\tfrac12\\log^2(x^{1/3})+O(1)=\\tfrac1{18}\\log^2x+O(1)$\n(C1: the ratio to $\\log^2x$ is $0.055556=1/18$ at $x=10^6,10^9,10^{12},10^{18}$). Good scales:\n$\\sum_e\\log e\\cdot\\frac xe(\\log x)^{-1-c}\\le\\frac x2(\\log x)^{-1-c}\\cdot\\frac{\\log^2x}{18}\n=\\frac{x}{36}\\log^{1-c}x$. Bad scales: $\\sum_{e\\in\\mathcal B}\\log e\\cdot\\frac xe\\le\\frac x2\\log x\\cdot\\delta$.\nWith $c=3$, the first term is $\\frac{x}{36\\log^2x}$ and the second is $\\le\\frac{x}{2\\log^2x}$ when\n$\\delta\\le(\\log x)^{-3}$. $\\square$\n\nNumbers (`NUMERIC`, C3): at $\\log x=30$, (S1) gives good/needed $=0.0556$ and (S2) with\n$\\delta=(\\log x)^{-4}$ gives bad/needed $=0.0333$ — both comfortably inside budget; at\n$\\delta=(\\log x)^{-3}$ the bad term is exactly at budget, which is why the lemma states $\\ll$, not $\\le$.\n\n**What this changes.** The obstruction is no longer \"we need ordinary Chowla at one prescribed scale\".\nIt is: *a quantitative almost-all-scales mixed correlation with an explicit exceptional log-measure*.\nAlmost-all-scales is precisely what the post-2017 literature proves, and the $e$-sum is what converts it\ninto an all-scales statement. The earlier dossier's reading — \"Chen's argument needs the bound at the\nsingle scale $x$, for every large $x$\" — is too pessimistic: it needs it on all but a\n$(\\log x)^{-3}$ fraction of the scales, and pays for the rest.\n\n### 3.3 What the existing almost-all-scales theorems supply, measured against (S1)/(S2)\n\n| input | scale-exception | rate | family-uniform? | reaches (S1)/(S2)? |\n|---|---|---|---|---|\n| Tao–Teräväinen, *ANT* 13 (2019), Cor 1.13 | log density $0$ | none stated | no | no — no rate, no uniformity |\n| Tao–Teräväinen, arXiv:2512.01739 (2025-12, rev. 2026-04) | \"small\" exceptional set | $\\ll\\mathcal L^{-c}$ on a **mean-corrected** correlation, modulus $W\\le\\mathcal L^{C}$ | no | only if the exceptional log-measure is $\\ll(\\log X)^{-3}$ **and** the pair-uniformity holds — to be checked |\n| Pilatte, arXiv:2310.19357 (preprint) | — | $\\sum_{n\\le x}\\lambda(n)\\lambda(n+1)/n\\ll(\\log x)^{1-c}$ | fixed shift $1$, same function | no (log-weighted, one shift) |\n| Guo, arXiv:2608.23500 (preprint) | exceptional *shifts*, log-measure $\\ll_A(\\log x)^{-A}$ | $(\\log x)^{1-c}$ | fixed pair | no (shift-exceptional, not scale-exceptional) |\n| OpenAI, 2026-09-24 manuscript (unrefereed) | none (all cutoffs) | $X(\\log X)^{-c}$, $c>0$ absolute | fixed functions only | would give (S1) **iff** $c\\ge4$ and uniformity in $z$ is added |\n\nTwo consequences worth separating.\n\n1. Even a *complete* ordinary two-point theorem with a power-of-log saving does **not** close the Chen\n   block unless $c\\ge4$ (or $c\\ge3$ with the exceptional measure of (S2)). This is a hard, checkable\n   quantitative demand, and it is new: the earlier reports asked for \"$o(x)$\", which is far too weak.\n2. Every input in the table is stated for **fixed** multiplicative functions. Our $g_2=\\lambda\\chi_z$ has\n   $z=x^{1/8}$ varying with $x$. That uniformity is not a convenience: it is the second half of the gap.\n\n### 3.4 The family is uniformly non-pretentious — `NUMERIC` (C5)\n\nFor $g_z=\\lambda\\chi_z$ we have $g_z(p)=-1$ for $p\\ge z$ and $0$ for $p<z$, so for the principal\ncharacter at $t=0$\n$$D^2(g_z,\\chi n^{it};X)=\\sum_{p<z}\\frac1p+\\sum_{z\\le p\\le X}\\frac2p\n=2\\log\\log X-\\log\\log z+O(1).$$\nMeasured at $X=10^8$: $D^2=5.174$ ($z=X^{1/8}$), $4.547$ ($z=X^{1/4}$), $4.264$ ($z=X^{1/3}$), i.e.\n$D=2.27,2.13,2.06$. The whole Chen range of sieve levels changes the pretentiousness distance by\n$O(1)$ — it does **not** grow with $x$. So a two-point theorem whose exceptional behaviour is controlled\nby $D$ should be extendable to the family, at a cost that does not depend on $x$. That is the technical\ncontent of \"family-uniform\" in §5.1.\n\n### 3.5 Why the pair $(\\mu,\\lambda)$ is the aligned pair — `PROVED`, `NUMERIC` (C4)\n\n$\\mu(n)\\lambda(n)=\\mu(n)^2$ for **every** $n$: both sides vanish if some $p^2\\mid n$, and for squarefree\n$n$, $\\lambda(n)=(-1)^{\\omega(n)}=\\mu(n)$ (verified $n\\le20\\,000$, $0$ mismatches). Consequently\n$\\mu$ and $\\lambda$ agree at **every** prime, so $D(\\mu,\\lambda;X)=0$ exactly: the pair is invisible to\npretentiousness. This is not a curiosity — it explains why the mixed pair is *not* easier than the\nsame-function pair, and why no pretentiousness argument can separate the two sides. The obstruction is\nentirely in the **shift**.\n\n---\n\n## 4.

This is a genuine\nreduction in kind: mean-square statements about correlations as the scale varies are exactly what the\nstructure theorem of Tao–Teräväinen produces, so (S2$'$) is the right shape to aim at. It is not proved;\nthe exponent $6$ is the exact price of the two Cauchy–Schwarz steps and of $\\lambda=(\\log x)^{-4}$\n(`NUMERIC`, C11: $\\eta=(\\log x)^{-5}$ misses the budget by a factor $300$ at $\\log x=30$,\n$\\eta=(\\log x)^{-6}$ meets it at ratio exactly $1/3$).\n\n*Gain if it works.* By Lemma 3.1 the entire large-divisor Type II remainder is $O(x/\\log^2x)$ — the first\ngenuine signed saving over the sieve baseline $x/\\log x$ in this strand, and the first time the\n$(\\mu,\\lambda)$ block is controlled.\n\n*Consequence for Chen / TPC.* Only the R2 leg. The ledger $R=R_1-\\frac12R_2+\\frac12A_3-\\frac12R_\\square$\nstill needs $R_1$ at level $>\\tfrac12$ (the level strip), $A_3$, and $R_\\square$; no $\\eta>0$ follows.\n\n### 5.2 **P2 (demoted). The \"bilinear\" route.**\n\nAfter opening $k_Q$, (2.1) reads $\\mathcal C_{3,Q}=-\\sum_q\\sum_T\\mu((qT-2)/3)\\lambda(T)\\chi_z(T)$: Möbius\non the **binary form** $qT-2$. It is tempting to call this bilinear and to expect a gain from summing over\n$q$ first. Two remarks kill that hope, and one keeps a door open.\n\n* The $e$-sum is smooth (weight $\\log e$, §3.1): it carries no arithmetic sign, so it can supply scale\n  averaging (used in P1) but **no cancellation**. A \"bilinear decomposition\" of a smooth weight is empty.\n* Without the shift, $\\sum_{qT=n}\\mu(q)\\lambda(T)=(\\mu*\\lambda)(n)$, whose mean is $\\asymp x/\\log^2x$ —\n  exactly the size we must beat. The shift $-2$ destroys the convolution: this is a shifted-convolution\n  object, and no multiplicativity evaluates it.\n* The door that stays open: the Bombieri–Friedlander–Iwaniec technology for $\\mu$ over *binary forms*\n  (sums $\\sum_{a,b}\\mu(a)\\mu(b)$ over $ab+1$-like regions) is the one existing machine of the right shape.\n  Checking its hypotheses for the hyperbolic region $ed\\in[x/2,x]$, $e\\le x^{1/3}$ is a concrete task, and\n  the answer is not obvious. Status: **no gain found**; not refuted.\n\n### 5.3 **P3. The $\\lambda=\\mu*1_\\square$ decomposition — one new lemma, no saving.**\n\n*The new lemma.* `PROVED` (and the rigorous tail an earlier mission demanded).\n\n> **Lemma 5.1.** On the support of $\\chi_z$ ($z=x^{1/8}$, $n=ed+2\\le x$), write\n> $\\lambda(n)=\\sum_{b^2\\mid n}\\mu(n/b^2)$. If $b\\ge2$ and $b^2\\mid n$ with $\\chi_z(n)\\ne0$, then every\n> prime factor of $b$ is $\\ge z$; hence $b\\ge z$. Therefore\n> $$\\lambda(n)\\chi_z(n)=\\mu(n)\\chi_z(n)+\\sum_{z\\le b\\le\\sqrt n}\\ \\sum_{b^2\\mid n}\\mu(n/b^2)\\chi_z(n),$$\n> and the second sum contributes to $R^{\\mathrm{large}}_{2,\\mathrm{II}}$ at most\n> $$O_\\varepsilon\\bigl(x^{7/8+\\varepsilon}\\bigr).$$\n\n*Proof of the tail.* For $b\\ge z$, the number of $d\\le x/e$ with $b^2\\mid ed+2$ is $\\le x/(eb^2)+1$;\n$k_Q\\le\\#\\{q\\in(Q,2Q]\\}\\le2Q/\\log Q\\le2x^{1/3}$, but the pointwise bound $k_Q(N)\\le\\log N/\\log Q\\le8$\nfor $Q\\ge x^{1/8}$ is what is used. Summing,\n$$\\sum_{b\\ge z}\\Bigl(\\frac{x}{eb^2}+1\\Bigr)\\cdot8\\ \\ll\\ \\frac{x}{ez}+8\\sqrt x ,$$\nand then over $e\\le x^{1/3}$ with weight $\\log e\\le\\log x$:\n$\\ll\\frac{x\\log^2x}{z}+x^{1/2}\\log^2x\\ll x^{7/8}\\log^2x$. $\\square$\n\n*The identity does not simplify the problem.* The $b=1$ term is\n$\\sum_d\\mu(d)\\mu(3d+2)\\chi_z(3d+2)k_Q(3d+2)$, and since $\\gcd(d,3d+2)=1$,\n$$\\mu(d)\\mu(3d+2)=\\mu\\bigl(d(3d+2)\\bigr)=\\mu(3d^2+2d)$$\nexactly. That looks like a gain — a *single* multiplicative function along a quadratic form — but\n$3d^2+2d=d(3d+2)$ is a product of two coprime linear forms, so this is **literally** the Erdős–Mirsky /\nChowla pair for $\\mu$ at $(d,3d+2)$. No simplification, only a change of notation.\n\n*What is actually gained.* (i) A rigorous $O_\\varepsilon(x^{7/8+\\varepsilon})$ where the earlier report\nhad an unproved assertion. (ii) The mixed pair $(\\mu,\\lambda\\chi_z)$ is replaced, at that cost, by the\n**same-function** pair $(\\mu,\\mu\\chi_z)$ — which matters because every theorem in §4 is stated for\nsame-function pairs, and the mixed-pair uniformity question disappears. (iii) No saving: the baseline for\nthe $b=1$ term is again the sieve's $x/\\log x$, so three to four logs are still needed.\n\n*Verdict.* `PROVED` lemma; **no** improvement toward the positivity criterion. Recorded so that the\nidentification \"$\\lambda\\to\\mu$ is free\" is not repeated without its price.\n\n---\n\n## 6.

Because of this I did not rest on the receipt; I ran my own stdlib check, which reads no file of the return.\n\nWhat holds (I checked by hand and with the receipt's independent arm):\n- Tao Thm 1.3's condition a1b2−a2b1=2 for (n, 3n+2).\n- μλ=μ².\n- The C9 opening identity, which is exact.\n- The C10 arithmetic (d≡16 mod 25, (3r+2)/25=2).\n- The λ=μ*1_□ identity with b≥z on z-rough n (C8a/C12).\n- The C5 D² formula and numbers.\n- The (S2') derivation X(λ)≤η²log x/(3λ²), with ratio 1/3 at η=(log x)^{-6}.\n- Lemma 5.1's conclusion O(x^{7/8+ε}).\n- The ledger verdict (Category C, no deposit), which does not depend on any of the defects below.\n\nWhat fails (my spot check and receipt #115 agree):\n1. C1. The printed 'ratio sum/log^2x=0.055556' at every x is the closed form 0.5·log²E/log²x, not the sum. The measured ratios are 0.053479 (1e6), 0.054587 (1e9), 0.055007 (1e12) and 0.055311 (1e18): an O(1)/log²x approach to 1/18. The C1 gate abs(1/18−0.5/9)<1e-12 is vacuous.\n2. C8b. 0.4561/0.4602/0.4615 adds the per-b counts. The union density of {d: b²|3d+2, some b≥2} is 3158/31609/316085 at N=1e4/1e5/1e6, i.e. 0.316, with limit 1−(6/π²)(9/8)=0.3161. The C8b gate is the literal True. 'Positive density' stands; the number 0.46 (in §7 and in the C8 note) is wrong.\n3. Lemma 3.1 (S1) c≥4 contradicts the lemma itself. With δ=0, the good-scale term at c=3 is x/(36 log²x)≪x/log²x, so every-scale needs only c≥3, as (S2) does. C3's own 'good/needed=0.0556' is computed at c=3. The c≥4 propagates to §3.3 (table, line 210), §4 (272) and §6 (384, 388). The proof's x/2 factor is not in the hypothesis: it gives x·log^{1-c}x/18, not x/36. This is harmless but wrong.\n4. C11/§7. 'ratio 444' matches neither row. The checker gives X(η=log^-5)/budget = 1.111e-2/3.70e-5 = 300 at log x=30 (133 at log x=20). The verification plan's '1.667e-2 against 1.25e-4' is the log x=20 row.\n5. Lemma 5.1 tail. Summing the '+1' term over e≤x^{1/3} gives ≈8x^{5/6}log x, not x^{1/2}log²x. The bound O(x^{7/8+ε}) still follows because 5/6<7/8.\n6. C9's −12 at x=3000, Q=11, z=5 uses roughness that excludes p=z. With the standard z-rough convention the value is −11 (receipt #115). The identity is exact under both conventions, so the convention should be stated.\n7. Gates: 5 of 13 receipt controls are missed (ctrl1, ctrl7 C1, ctrl8 C8b, ctrl9 C3, ctrl10 C2 only tests the Q=100 row). The 'all checks pass' line therefore carries less than it reads.\n\nRung: measured holds for the PROVED/NUMERIC core once items 1–6 are corrected before circulation. None of them changes a conclusion. Attribution: #6224 and the cited literature are named, and I found no unnamed project source. No also_credit is needed.\n\nWhat would falsify the accept: a family-uniformity gap in Corollary 2.1 over e≤x^{1/3}. S_e is written with λ(3d+2) on an e-dependent range while N=ed+2, and Tao's constant depends on the forms' coefficients. The report should state which form S_e uses (advisory).","also_fix":[{"note":"C1/Lemma 3.1 proof: replace 'the ratio to log^2x is 0.055556=1/18 at x=1e6..1e18' with the measured sum/log^2x = 0.053479, 0.054587, 0.055007, 0.055311 (-> 1/18 with an O(1)/log^2x term).
