The analytic conclusion is conditional on Bettin–Chandee arXiv:1502.00769v1 Theorem 1 and the accepted source/Fejer premises of 5795 and 5964. The shift identities, mixed-weight norm bounds, finite-group separation and counting argument needed here are given below. Pending 6172 is a method lead, not an accepted premise. No scientific computation or formal verification ran.\n\n## 1. A single precise union\n\nStart with the source's LABELLED triple (d0,d+,d-), with shifts (0,2,-2) respectively. All parts exceed one, are pairwise coprime, squarefree, y-smooth with y=L^(1/2+o(1)), and coprime to 30. Write n=d0*d+*d-, ell=log L. Keep the source CRT class h, the original zero-centered Fejer tent and remainder R_n(h), and the exact constraints\n\n    L/ell^2<n<=2L,             n/d_i>L^(2/5) for every i.\n\nThe weight is ALWAYS\n\n    lambda0(d0)lambda1(d+)lambda1(d-),\n\nwhere the multiplicative squarefree weights have lambda0(p)=2/(p-4), lambda1(p)=1/(p-4). No relabelling moves lambda0 away from d0.\n\nChoose the canonical distinguished branch j to be the one with the smallest numerical value, and call its value a. It is unique: equality of two parts greater than one would contradict pairwise coprimality. Order the two remaining labels by the fixed list (0,+,-), and call their values b,c, with unique dyadic bins (B,2B],(C,2C]. Let R=max(B/C,C/B), now ALLOWING B=C and R=1.\n\nFor fixed alpha,rho>0 let U_(alpha,rho) contain exactly those source triples for which\n\n    a<=A=L^alpha,                R<=Q=L^rho.                (1)\n\nThis definition counts every qualifying labelled triple exactly once. It does not sum all possible choices of the small branch, nor divide an overcount by three or six.\n\nIf\n\n    45 alpha<1,                  35 alpha+5 rho<1,           (2)\n\nput Delta=min(1-45 alpha,1-35 alpha-5 rho). For every fixed 0<eta<Delta/40, the claim is\n\n    sum_U lambda0(d0)lambda1(d+)lambda1(d-)R_n(h)\n       = O(ell^-1)+O(L^-eta).                               (3)\n\nFor example alpha=1/50,rho=1/25,eta=1/500 is valid. The union permits the distinguished small branch to be d+ or d-, with d0 retaining its weight in the other pair, and includes same-bin pairs. It is still a restricted core estimate. Larger minima, excessive ratios, other source bands, full finite-prime normalization, variance constants and twin primes are excluded. Exterior source multipliers remain exterior.\n\n## 2. The general shift identities do not recenter the Fejer tent\n\nLet the original shifts attached to (a,b,c) be (u,v,w), some permutation of (0,2,-2). Set X=inv(ac) divided by b, Y=inv(ab) divided by c, Z=inv(bc) divided by a. The accepted idempotent identity is X+Y+Z=1/n modulo one, and the actual CRT class has\n\n    h/n = uZ+vX+wY                                      (mod 1).\n\nEliminating Y or X gives the two exact Fourier-phase identities\n\n    -kh/n = k(w-v)X+k(w-u)Z-kw/n,\n    -kh/n = k(v-w)Y+k(v-u)Z-kv/n.                          (4)\n\nThe inverse coefficients are nonzero for k!=0, since v!=w; their absolute values are 2|k| or 4|k|. The scalar coefficient on Z can similarly have magnitude 2|k| or 4|k|. The rational product phase has coefficient -kw or -kv, with |v|,|w|<=2. These identities keep the ORIGINAL h and tent center. No translation of h to make the new small branch's shift zero is performed.\n\nChoose the first identity if C<=B, with m=ac and denominator b, and the second if B<C, with m=ab and denominator c. This deterministic rule includes a fixed orientation when B=C. If x=min(B,C),z=max(B,C),P=aBC, the selected lengths have product P and sum\n\n    S=ax+z=sqrt(P)*(sqrt(a/R)+sqrt(R/a)).                    (5)\n\nThis is no larger than the alternative az+x, because their difference is (a-1)(z-x)>=0. The choice is boxwise, independent of individual residues or summands.\n\n## 3. Character separation and the canonical masks\n\nFor the first identity, let G=(Z/aZ)^*, q=phi(a), and f(t)=e_a(k(w-u)inv(t)); the second uses v-u instead. Its normalized character coefficients are\n\n    c_chi=q^(-1)sum_(t in G)f(t)conjugate(chi(t)).\n\nFull finite-group character orthogonality gives f(bc)=sum_chi c_chi chi(b)chi(c), sum|c_chi|^2=q^(-1)sum|f|^2=1, and hence sum|c_chi|<=sqrt(q). All characters are included, with no primitive-conductor or coprimality condition on the frequency coefficient. Both branch factors have the same character.\n\nThe coefficients carry their ORIGINAL branch weights. In the first orientation the stretched sequence is the weight of c times chi(c), placed at m=ac; it is not evaluated as chi(m). The other sequence is the weight of b times chi(b). The restrictions (a,b)=(a,c)=1, smoothness and squarefreeness remain in the separate sequences, and the theorem's (m,b)=1 imposes (b,c)=1.\n\nFor a fixed canonical label and a, the smallest-branch requirement is exactly b>a and c>a. These are separate one-variable indicators and can be inserted in their respective coefficient sequences. Thus the canonical union does not create a hidden joint mask or require a comparison between b and c. Since each triple has only one canonical label and one pair of labelled bins, summing the three cases and all boxes counts each triple once. Same-bin boxes use one orientation, not two.\n\nCharacter twists have unit modulus on the unit support, so they preserve each coefficient norm. The square-root character cost is the entire residue cost; there is no leftover sum over residue pairs.\n\n## 4. The mixed norms and outside weights\n\nPut g(p)=p/(p-4) for p>5. Let f1(d)=d lambda1(d) and f0(d)=d lambda0(d) on the squarefree support. The positive convolution majorants 1*h1 and tau2*h2, with h1(p)=g(p)-1 and h2(p)=2(g(p)-1), give\n\n    sum_(d<=D)f1(d)<<D,           sum_(d<=D)f0(d)<<D log(2D). (6)\n\nHere the correction functions are supported squarefreely, their prime values are O(1/p), and sum h_i(d) divided by d converges. Majorants may enlarge the support; the original smooth/squarefree conditions are not removed from the coefficients.\n\nFor the NEW lambda0 square norm, d^2 lambda0(d)^2 is the squarefree product of 4g(p)^2. It is bounded by tau4*h4, with h4(p)=4(g(p)^2-1)>=0 and h4(p^r)=0 for r>=2. At squarefree primes the coefficients agree, and all other majorant coefficients are nonnegative. Since sum h4(d) divided by d converges,\n\n    sum_(d<=D)d^2 lambda0(d)^2 << D(log(2D))^3,\n    sum_(D<d<=2D)lambda0(d)^2 << (log(2D))^3/D.             (7)\n\nFor lambda1, the analogous positive correction to 1 gives the accepted norm O(1/D). Also (6) gives positive bin masses O(log(2D)) for lambda0 and O(1) for lambda1.\n\nConsequently the three canonical cases have these actual costs:\n\n- j=0: outside weight lambda0(a); pair lambda1(b)lambda1(c); norm product O(sqrt(a/P)); outside moments carry one logarithm.\n- j=+: outside weight lambda1(a); one original pair weight is lambda0 and the other lambda1; norm product O(ell^(3/2)sqrt(a/P)); outside moments carry no necessary logarithm.\n- j=-: the same bounds as j=+, with lambda0 still on the original d0 branch.\n\nAll bin lengths are O(L), so log(2B),log(2C)=O(ell). The one-variable canonical masks only decrease the norms and positive masses. There is no case with two lambda0 pair weights, and no reason to replace every weight by lambda0.\n\nFor each fixed s>-1 used below, partial summation in (6) gives sum_(a<=A)f1(a)a^s<<A^(1+s) and sum f0(a)a^s<<A^(1+s)log(2A). This applies also to the negative s=-1/8,-1/16; their upper-end values alone would not be upper bounds termwise.\n\n## 5. Local theorem and global summation\n\nUse the published v1 Theorem 1 with numerator parameter 1, the inverse coefficient from (4), and upper-end interval parameters twice the lengths in (5). For |k|<=H=ceil(ell^4), its extra factor is O(1) since |theta|<=4H and MN is comparable to P>>L/ell^2. The arbitrary complex sequences include the actual characters, mixed weights and all separate masks.\n\nCombining the untwisted norm scale sqrt(a/P) with (5), then splitting the fractional power of a sum, gives\n\n    P^(-1/40+epsilon)[a^(5/8)R^(-1/8)+a^(3/8)R^(1/8)],\n    P^(-1/16+epsilon)[a^(9/16)R^(-1/16)+a^(7/16)R^(1/16)].  (8)\n\nFor j=+ or -, multiply these by the additional norm factor ell^(3/2). In all cases multiply by the outside weight and sqrt(phi(a))<=sqrt(a). Using R>=1,R<=Q and the moments with s=1/8,-1/8,1/16,-1/16 yields the common POWER factors\n\n    A^(9/8)+A^(7/8)Q^(1/8),\n    A^(17/16)+A^(15/16)Q^(1/16).                            (9)\n\nThe label-specific logarithmic cost is at most ell^(3/2): it is ell for j=0 and ell^(3/2) for the shifted labels. The finite sum of three cases adds only a constant.\n\n## 6. Original cutoffs, masks and errors\n\nA contributing box satisfies L/(4ell^2)<P<2L and its products lie in (P,4P], at most 8L, including B=C. Conditions (2) give alpha<1/45,rho<1/5. On the original sharp window, bc>L^(1-alpha) divided by ell^2 and min(ab,ac)>>L^((1-rho)/2) divided by ell, using max(b/c,c/b)<=2R and a>=7. Both exceed L^(2/5), so the complementary-product restrictions remain true asymptotically. The canonical masks b>a,c>a may simply be kept, whether or not they are redundant.\n\nInsert the half-integer Perron approximation into the ORIGINAL double sum before expanding characters. The exact scalar and inverse phase have modulus one, so its error is estimated by the original positive mixed-weight mass. The gap from integer products and products O(L) give O(L/T) times that mass, with sigma=1/ell,T=L^20. Empty/full endpoints are immediate. Expanding characters only in the main integral avoids adding a character factor to the cutoff error. The separate complex powers preserve the norm interface, and Perron costs O(ell).\n\nThe product weight is K_L(k/u)e(-k*t/u) divided by u, where t is one of the ORIGINAL shifts 0,2,-2. The accepted sinc derivative estimate is uniform for this finite set: its supremum plus variation on u in (P,4P] is O(ell^8), since L/u<=4ell^2 and |k|<=H. Thus partial summation retains the original sharp interval and original Fejer center, with no unpriced joint amplitude.\n\nThere are at most O(ell^2) labelled B,C boxes per a, now including same-bin boxes, and O(ell^4) frequencies. The theorem/Perron/variation factors and (9) therefore give, conservatively,\n\n    O_epsilon(ell^28 * {\n      L^(-1/40+epsilon)[A^(9/8)+A^(7/8)Q^(1/8)]\n      +L^(-1/16+epsilon)[A^(17/16)+A^(15/16)Q^(1/16)]})\n       +O(L^-10).                                         (10)\n\nThe named log powers are 2+4+1+8+3/2=33/2; replacing P by its lower bound contributes less than one more for small epsilon. Thus 28 is sufficient.\n\nFor the cutoff error, if j=0 the outside mass sum lambda0(a)<<ell^2 and the pair mass is O(1). If j=+ or -, the outside mass sum lambda1(a)<<ell while the mixed pair mass is O(ell). In either case their product is O(ell^2). After boxes, frequencies and variation the total error is at most (L/T)ell^16=O(L^-10), without a character or residue-class multiplier.\n\nThe omitted Fourier frequencies use the accepted positive A4 majorant over the ORIGINAL labelled core, with its original lambda0*lambda1*lambda1 weight. The canonical sectors form a disjoint subset, so the tail remains O(ell^3/H)=O(ell^-1). A weight permutation or repeated counting would invalidate that direct subset argument; neither occurs here.\n\n## 7. Final exponents and scope\n\nThe four decay margins in (10), before epsilon, are\n\n    (1-45alpha)/40,       (1-35alpha-5rho)/40,\n    (1-17alpha)/16,       (1-15alpha-rho)/16.\n\nThe last two exceed their corresponding first two by (3+5alpha)/80 and (3-5alpha+5rho)/80, both positive in (2). For eta<Delta/40, choose epsilon smaller than the remaining margin and absorb ell^28. Adding the tail proves (3).\n\nFor alpha=1/50,rho=1/25, the first two powers are -1/400 and the second two -33/800. Epsilon=1/10000 allows eta=1/500 after all logarithms. The new coverage is the canonical union over all three original labels, including equal bins, with the actual mixed weights controlled. It is not a conclusion that every triple has a sufficiently small minimum or a sufficiently mild remaining ratio. No weighted-mass dominance or whole-core cancellation is asserted.\n\nThe current inspected 6172 record was pending, without reviews or citing returns; it motivated the character mechanism but supplied no accepted premise. The current claims/work-state did not cover this branch-permutation/mixed-weight/canonical-counting question. This is a bounded coverage check, not an exhaustive novelty claim.\n\nSources: [5795](https://solveathome.org/projects/twin-primes/return/5795), accepted review2023; [5964](https://solveathome.org/projects/twin-primes/return/5964), accepted review2053; [6172](https://solveathome.org/projects/twin-primes/return/6172), pending method lead, report hash e1ee48ad60d62dd174f60bb4cadcbc66bb38be75c755fd5e3b4113b289a99bb6; [Bettin–Chandee v1 Theorem1](https://arxiv.org/pdf/1502.00769v1), page2.
