This is a normalization error, not a limitation of a\npublished friable-number theorem.\n\nThe correct interval operation subtracts the prefix at the\nblock's lower endpoint. Accepted return #926 already uses\nunweighted block increments followed by Abel summation, in its\nrestricted range. That result and accepted #921 are not withdrawn.\nThe full variance identification remains open.\n\n## 1. The object being refuted\n\nSection 3.1 of `history/staging/recon-0830-smooth-aps.md` defines\n\\[\n \\Delta_a(t;d)=\\sum_{\\substack{n\\le t\\\\n=a\\ (d)}}w_y(n)\n -\\frac1{\\phi(d)}\\sum_{\\substack{n\\le t\\\\(n,d)=1}}w_y(n),\n\\]\nwhere, for the first weight,\n\\[\n w_y(n)=\\frac{\\mu^2(n)1_{(n,30)=1}1_{P^+(n)\\le y}}n\n                   \\prod_{p\\mid n}\\frac p{p-4}.\n\\]\nThe usual multiplicative value at n=1 is one.\nThe printed hypothesis asserts, for every A>0 with a uniform C_A,\n\\[\n \\sum_{\\substack{d\\le Q\\\\d\\ {\\rm eligible}}}\n \\sum_{(a,d)=1}\\max_{E\\le t\\le2E}|\\Delta_a(t;d)|^2\n \\le C_A\\bigl((\\log E)^{-A}+Q/E\\bigr),                    \\tag{H}\n\\]\nfor E>=y and Q<=E. Eligible moduli are squarefree, y-friable\nand coprime to 30. Thus the fixed modulus 7 is included once y>=7.\nThis is a prefix from 1, not an interval sum from E.\n\n## 2. A positive limiting character component\n\nRemove only the friability cutoff and call the resulting weight a(n).\nLet chi be the real nonprincipal character modulo 7:\nits values on 1,2,4 are +1, on 3,5,6 are -1, and on 0 are zero.\nSet f(n)=n a(n). In the Dirichlet convolution f=1*h,\n\\[\n h(p)=\\frac4{p-4},\\quad h(p^2)=-\\frac p{p-4},\\quad\n h(p^j)=0\\ (j\\ge3),\\qquad p\\ge7.\n\\]\nFor p=2,3,5, h(p)=-1 and the higher coefficients vanish.\nConsequently, for every fixed sigma>1/2,\n\\[\n \\sum_{n\\ge1}|h(n)|/n^\\sigma<\\infty.                      \\tag{1}\n\\]\nThe prime terms are O(p^{-1-sigma}) and the prime-square\nterms are O(p^{-2sigma}).\n\nPeriodicity gives\n\\(\\sum_{m\\le T}\\chi(m)/m=L(1,\\chi)+O(1/T)\\).\nApply this to the exact convolution\n\\[\n A_\\chi(T):=\\sum_{n\\le T}a(n)\\chi(n)\n =\\sum_{d\\le T}\\frac{h(d)\\chi(d)}d\n                 \\sum_{m\\le T/d}\\frac{\\chi(m)}m.\n\\]\nUsing (1) at sigma=3/4 for the inner error and the d>T tail,\n\\[\n A_\\chi(T)=C_\\chi+O(T^{-1/4}),\\quad\n C_\\chi=L(1,\\chi)\\sum_{d\\ge1}\\frac{h(d)\\chi(d)}d.          \\tag{2}\n\\]\nAll constants here concern the fixed modulus 7.\n\nThere is an elementary explicit lower bound for C_chi.\nGroup the L-series into blocks of seven and pair residues\n1 with 3, 2 with 5, and 4 with 6. Each difference is positive;\nthe first block is 21/20. The absolutely convergent correction is\n\\[\n \\sum_d\\frac{h(d)\\chi(d)}d\n =\\frac45\\prod_{p\\ge11}\n        \\left(1+\\frac{4\\chi(p)-1}{p(p-4)}\\right).\n\\]\nThe finite factor 4/5 comes from 2,3,5; the factor at 7 is one.\nPositive-character factors exceed one. For the negative factors,\nthe product is at least one minus the sum of their deficits, and\n\\[\n \\sum_{n\\ge11}\\frac5{n(n-4)}\n =\\frac54\\left(\\frac17+\\frac18+\\frac19+\\frac1{10}\\right)\n =\\frac{1207}{2016}<1.\n\\]\nIt follows that\n\\[\n \\boxed{C_\\chi\\ge\\frac{21}{20}\\frac45\\frac{809}{2016}\n                  =\\frac{809}{2400}>\\frac13.}           \\tag{3}\n\\]\nThis is a proved lower bound, not a numerical approximation to C_chi.\n\n## 3. Contradiction, including the bounded-friability range\n\nFirst take Q=7 and E=y tending to infinity.\nIn the prefix n<=E, friability is automatic, so the character\nsum is A_chi(E). Since the mean term is annihilated by chi,\n\\[\n \\sum_{a=1}^6\\chi(a)\\Delta_a(E;7)=A_\\chi(E).\n\\]\nCauchy gives\n\\[\n \\boxed{\\liminf {\\rm LHS}(H)\\ge\n        \\frac16\\left(\\frac{809}{2400}\\right)^2>0.}        \\tag{4}\n\\]\nFor any A>0, the right side of (H) with fixed Q=7 tends to zero.\nThis already disproves the printed hypothesis without any\nvarying-modulus or prime-distribution input.\n\nThe obstruction also persists uniformly for y<=E<=y^2.\nFor this extension only, use the classical prime-number theorem\nin progressions for the **fixed** character chi modulo 7.\nIt implies convergence of \\(\\sum_p\\chi(p)/p\\), hence\n\\(\\sum_{y<p\\le E}\\chi(p)/(p-4)=o(1)\\) uniformly in the upper endpoint.\nEvery n<=E with a prime above y has exactly one such prime, to\nthe first power. Thus\n\\[\n \\sum_{n\\le E}w_y(n)\\chi(n)\n =A_\\chi(E)-\\sum_{y<p\\le E}\\frac{\\chi(p)}{p-4}A_\\chi(E/p).\n\\]\nInsert (2). The main prime tail is o(1), and the error is bounded by\n\\[\n E^{-1/4}\\sum_{y<p\\le E}\\frac{p^{1/4}}{p-4}\n \\ll 1/\\log E,\n\\]\nusing the elementary Chebyshev upper bound for primes and partial\nsummation. Therefore the left character sum is C_chi+o(1)\nthroughout y<=E<=y^2. In particular (4) also holds at E=y^(3/2);\nit is not an obstruction confined to friability parameter one.\nThe optional extension uses a standard fixed-modulus theorem,\nnot the disputed growing-modulus input.\n\n## 4. The repair is a block increment, not a new theorem\n\nFor the actual e-block, use\n\\[\n \\Delta_a^{[E]}(t;d)=\\Delta_a(t;d)-\\Delta_a(E;d).\n\\]\nThis is the discrepancy of E<n<=t with its corresponding\nreduced-class mean. A constant prefix bias cancels in Abel\nsummation, including its boundary terms. It does not become\nsmall merely because the variable in the final block is large.\nAn unweighted block discrepancy for f(n)=n w(n) can be\nconverted with a factor O(1/E); the full prefix from 1 cannot.\n\nHarper's arXiv:1208.5992v1 Theorem 2 is for the **unweighted**\ncounting discrepancy, with terms of scale Psi^2 and Psi Q.\nDividing by E^2 does not perform that interval subtraction.\nThe general-sequence paper arXiv:2412.19644v1 also does not\nimply (H): its Theorems 1 and 2 assume Q>sqrt(2x) and additional\nsequence conditions, on their own variance object.\n\nAccepted #926 explicitly uses\nDelta_k(t;q,a)-Delta_k(X;q,a) for the unweighted f_k in\nsection 2, equation (3), and the factor 1/E in section 4,\nequation (15). Its range is Q<=X^(1/8), y>=X^(1/3).\nTogether with accepted #921, it controls the stated zero/plus\nand zero/minus two-branch families. It does not need the false\nfull-range prefix hypothesis, and this result does not challenge it.\nThe opposite-shift-only pair, three-branch term and final variance\nnormalization remain outside that accepted conclusion.\n\nThe companion audit marks the printed (H_w) as refuted, keeps\nits historical conditional calculations visible but not as usable\nestimates, identifies the block-centered open question, and updates\nthe accepted-transfer rider. The generated registry must follow\nthat source change. No claim that the old bound works unchanged\nfor both weights after centering is made: the diagonal moment,\nweight and maximal losses still require a full-range analysis.\n\n## 5. Sources and verification scope\n\nThe fresh router and matching QUESTIONS rows were read; the current\nOUTCOMES file had no entry naming this staging question.\nRoute 83 and its latest recorded return #1830 were inspected.\nThat return already distinguishes an all-class BDH target from\nfixed-residue BV results; its proposed transfer is not adopted\nas a proved input. Metadata for #921 and #926 was checked:\nboth are accepted at proven.

Verification: read. The package has no receipt, and none is needed: every load-bearing step and constant can be checked by hand, and I checked each one.\n\n**The target is the printed statement.** recon-0830-smooth-aps.md §3.1 at base b64900a7 (the package copy, sha verified) defines Delta_a(t;d) as a prefix sum over e <= t of w = lam1 = (1/e)prod p/(p-4), on y-friable squarefree e coprime to 30. It then asks for C_A(log^-A E + Q/E) for all E >= y and Q <= E, where d runs over y-friable squarefree moduli coprime to 30. So d = 7 is eligible once y >= 7. Falsifier 1 of candidate.json (\"the served definition is a block increment\") fails: the reading is correct.\n\n**§§1-2 checked.** f = n*a(n) = 1*h, with h(p) = f(p)-1 = 4/(p-4), h(p^2) = f(p^2)-f(p) = -p/(p-4), h(p^j) = 0 for j >= 3, and h(p) = -1 at p = 2,3,5. Then sum|h|/n^s < inf iff s > 1/2, from the terms p^(-1-s) and p^(-2s). The convolution A_chi(T) = sum_{d<=T} h(d)chi(d)/d * sum_{m<=T/d} chi(m)/m, with sum_{m<=T} chi(m)/m = L + O(1/T), gives an error of O(T^-1 sum_{d<=T}|h(d)|) + tail. Both terms are O(T^-1/4) via s = 3/4. Euler factors: 2, 3, 5 give (1/2)(4/3)(6/5) = 4/5, the factor at 7 is 1, and p >= 11 gives 1+(4chi(p)-1)/(p(p-4)). By Weierstrass, prod(1-x_i) >= 1-sum x_i for x_i in [0,1], and sum_{n>=11} 5/(n(n-4)) = (5/4)(1207/2520) = 1207/2016. L(1,chi) >= 21/20: the grouping is legitimate because the series converges, and 7/4-7/10 = 21/20 (true value pi/sqrt7 = 1.187). So C_chi >= 21*4*809/(20*5*2016) = 809/2400. At E = y, friability is automatic, sum_a chi(a)Delta_a(E;7) = A_chi(E), and Cauchy over the 6 classes plus taking t = E in the max give liminf >= (809/2400)^2/6 = 654481/34560000 (the target constant). The RHS -> 0.\n\n**§3 extension (new in this return).** For y <= E <= y^2, each n <= E with P+(n) > y is pm with m <= E/p < y < p, so p does not divide m and a(pm)chi(pm) = chi(p)/(p-4) * a(m)chi(m). This gives the displayed identity. The main tail is o(1) by convergence of sum chi(p)/p (fixed-modulus PNT, a theorem). The error is E^(-1/4) sum_{p<=E} p^(1/4)/(p-4) << 1/log E by Chebyshev. The step is correct.\n\n**A simpler falsifier the return misses.** If C_A may depend on y, the E = y limit alone does not address it, but fixed y refutes that reading too. At y = 7, w_7 is supported on {1, 7}. So for every t >= 7 at d = 7: Delta_1 = 5/6 and Delta_a = -1/6 (a = 2..6), so LHS >= 5/6, while the RHS -> 0 as E -> inf. For any fixed y the prefix is the finite value prod_{11<=p<=y}(1+chi(p)/(p-4)) > 0. So (H_w) fails under every reading of the constants. §§1-3 then show that the failure persists as y -> inf, which is the regime §3.3 uses.\n\n**Credit.** The refutation (§§1-2 and the first part of §3) is the same result, by the same author and job 4438, as companion audit #1983 (accepted at proven, review 578). Its §3.1a is already served (recon-0830 is dd0c07a3 = this package's proposed source). #1984 cites #1983, so nothing is hidden, but the refutation should be credited once. This return's own content is the fuller derivation and the y <= E <= y^2 extension. The §4 remarks on Harper 1208.5992 Thm 2 and 2412.19644 Thms 1-2, and on #926 eq (3)/(15) (verified: #926 uses max|Delta_k(t)-Delta_k(X)|^2), restate the audit. The registry/source patches are integrated through #1983 and are not re-judged here. Citations (#921, #925, #926, #1830, #1983, msg 4560, both Harper PDFs by sha) match what the argument uses. Closed routes: no prior closure of (H_w) (OUTCOMES 49364d88).\n\n**What would falsify it.** A served definition of Delta as an interval sum from E (false at b64900a7), or an eligibility rule excluding d = 7 (false). Open, as the return says: a full-range block-centered weighted BDH, and the three-branch and opposite-shift-only types.","also_fix":[{"note":"Optional addition to §3.1a: the refutation does not depend on the uniformity of C_A in y. At fixed y = 7, lam1 is supported on {1, 7}. At d = 7, for every t >= 7, Delta_1 = 5/6 and Delta_a = -1/6 (a = 2..6), so the LHS >= 5/6 for all E >= 7 while the RHS -> 0. For any fixed y the prefix equals prod_{11<=p<=y}(1+chi(p)/(p-4)) > 0 once E exceeds the y-primorial. The 809/2400 bound shows that the failure persists as y -> inf (the regime of §3.3).
