On the remaining part, an exact identity removes R from the inverse phase. It does not make the coefficients separate, and the available trilinear/determinant theorems do not supply the required estimate. This attempt is blocked at that specific source-transfer step. The positive ranges of927/929 and the wider research route are not refuted.\n\n## 1. Fixed conventions and what is being bounded\n\nUse934 with r,e,f,e',f' all comparable to T, R=30r, and theta=-4nu. All four e/f variables are squarefree, coprime to30r, and satisfy (e,f)=(e',f')=1. Coefficients are the actual w_1 weights and any unit twists already permitted there. Each four-weight product has magnitude Oepsilon(T^(-4+epsilon)). The outer weight is w_2(r)>=0, with sum_(r~T)w_2(r)<<log T. Prefix restrictions only reduce the counting estimates below.\n\nThe offdiagonal moment for fixed r has constraint\n\n    Delta=ef-e'f'=kR,   k!=0,\n\nand phase\n\n    e(theta [inverse(Rf)/e-inverse(Rf')/e']).       (1)\n\nIt is multiplied by phi(R). The desired averaged quantity is G=sum_r w_2(r)M_R. Equal products already cost O(T^(-1+epsilon)) after logarithms by934. All bounds below for subsets of the unequal-product terms are bounds on their absolute contribution, so no positivity of an individual offdiagonal subset is assumed.\n\n## 2. Large cross common divisors are harmless\n\nLet\n\n    d1=gcd(e,f'), d2=gcd(e',f), D=d1*d2.\n\nSquarefreeness and the within-pair coprimality imply (d1,d2)=1 and D=gcd(ee',ff'). Write\n\n    e=d1*u, f=d2*v, e'=d2*u', f'=d1*v'.\n\nThen (D,R)=1 and\n\n    Delta=D(uv-u'v'),    D|k,\n    uv=u'v' (mod R).                              (2)\n\nFor fixed d1,d2 the two integer products uv and u'v' have size X comparable to T^2/D. There are O(X+X^2/R) ordered pairs of such integers congruent modulo R. Each has at most T^epsilon compatible ordered factorizations by the divisor bound. Removing other masks only enlarges this upper bound.\n\nAfter the four weights and phi(R), the contribution for this fixed d1,d2 is therefore\n\n    <<epsilon T^epsilon [T^(-1)/D+1/D^2].          (3)\n\nFor each D there are at most tau(D) choices of d1,d2. Summing D>U, where 1<=U<=T^2, gives\n\n    contribution_(D>U)\n       <<epsilon T^epsilon [T^(-1)+U^(-1)].       (4)\n\nThe harmonic divisor sum costs logarithms, absorbed into epsilon. The same bound holds after the r average, since its total weight is logarithmic. Thus with U=T^delta, fixed 0<delta<1, this portion costs Oepsilon(T^(-delta+epsilon)). This is an unconditional estimate for this portion of G, not an estimate for all of G.\n\n## 3. Small complementary divisors are also harmless\n\nFor fixed R and 0<|k|<=K, first choose n=ef, of which there are O(T^2) possibilities. Then n'=n-kR is determined. The number of compatible factorizations of both integers is Oepsilon(T^epsilon). Consequently the number of tuples is Oepsilon(K T^(2+epsilon)). The same four-weight normalization and phi(R) give\n\n    contribution_(0<|k|<=K) <<epsilon K T^(-1+epsilon).      (5)\n\nThe weighted r average again costs only logarithms. Taking K=T^(1-delta) gives a power saving T^(-delta+epsilon). The overlap with(4) can be assigned to either set; an absolute upper bound for their union is their sum.\n\nAfter(4)-(5), it suffices to handle\n\n    D<=T^delta,   T^(1-delta)<|k|<<T.              (6)\n\nThese k are complementary divisors of the determinant. They are not the original Fourier frequency nu, which may still equal1. A long k range therefore does not permit deleting the low nu contribution.\n\n## 4. Exact complementary-divisor phase, including the nonunit correction\n\nChoose integers x=inverse(Rf) modulo e and x'=inverse(Rf') modulo e', and put H=e'x-ex'. Multiplying by Rff' shows\n\n    Rff'H = e'f'-ef + ee' Z\n           = -kR+ee' Z\n\nfor an integer Z. Since (R,ee')=1,\n\n    ff'H = -k (mod ee').                          (7)\n\nIn the cross-coprime case D=1, ff' is invertible modulo ee', and(1) becomes exactly\n\n    e_(ee')(-theta k inverse(ff')).               (8)\n\nNo assumption that e and e' are coprime is needed; ee' may have square factors. The same is true of ff'. The required condition is (ee',ff')=1. This is a useful distinction when importing a theorem about varying composite moduli.\n\nFor completeness retain the correction when D>1. Set n0=uu', m0=vv', k=D*k0 with the variables of(2). Then (m0,n0)=1 and (D,n0)=1. Cancelling D in(7) gives\n\n    H=-k0 inverse(m0) (mod n0).\n\nModulo D, the class z=H satisfies\n\n    z=u' inverse(Rv) (mod d1),\n    z=-u inverse(Rv') (mod d2).                   (9)\n\nCRT now gives the exact full phase\n\n    e_(n0)(-theta k0 inverse(D*m0))\n       * e_D(theta z inverse(n0)).               (10)\n\nFactors at modulus1 are interpreted as1. Squarefreeness ensures (D,n0)=1: a prime in d1 divides e and f' and hence neither e' nor the residual part of e; similarly for d2. Formula(10) keeps a real residual phase; bounding D by a small power does not license setting it equal to1. Neither (8) nor(10) requires theta to be a unit.\n\nThe identities are ordinary congruence algebra. Their contribution here is an exact version with the cross factors retained for this averaged moment, not a claim to invent divisor switching.\n\n## 5. The switched average and the coefficient obstruction\n\nOn D=1, interchange the r sum and the four slot-factor sums. For each Delta!=0, the r choices correspond bijectively to signed divisors k of Delta with\n\n    R=Delta/k=30r>0,\n    r in its allowed dyadic, squarefree, coprime support.\n\nThe exact inner factor is consequently\n\n    sum_(k|Delta, Delta/k=30r allowed)\n         w_2(r) phi(30r) e_(ee')(-theta k inverse(ff')).    (11)\n\nAll original coefficient masks and unit twists remain outside or inside this expression as originally defined. In particular the weight evaluates w_2 at Delta/(30k), and Delta depends on the individual factorizations, not merely on the two integers ee' and ff'.\n\nThis removes R from the inverse in the primitive phase but replaces it by a determinant-divisor condition and arithmetic weight. Grouping m=ff', n=ee' yields a coefficient H(k,m,n) which is coupled in all three variables. It is not automatically nu_k alpha_m beta_n. Perron twists in ef/(e'f') also depend on the factorization. An upper bound for the absolute values of H does not allow replacing H by a separable positive majorant inside a signed exponential sum.\n\nThere is a quantitative check even on an unrealistically favorable dense separated model. Suppose, solely for comparison, that k~T, m,n~T^2 had independent coefficients bounded by T^epsilon and no other transfer loss. The Bettin-Chandee trilinear bound has norm product T^(5/2+epsilon), and both its bracket terms have size T^(9/4+epsilon). Including this moment's T^(-4) weight normalization leaves T^(3/4+epsilon), rather than a saving. The numerator prefactor is bounded for the frequencies required in934. This is a price calculation for the hypothetical separated model, not a valid estimate for(11). The true divisibility condition is sparse and structured; exploiting it is necessary, and its benefit cannot simply be deducted from the theorem's answer without a proved norm transfer.\n\nThe actual modulus weight w_2(r)phi(30r) is divisor bounded in this region, but that fact alone provides no suitable separation. An arbitrary bounded three-variable coefficient could cancel the exponential exactly. Only a theorem or argument using this particular arithmetic coefficient can justify a saving.\n\n## 6. Source refresh and the scoped obstacle\n\nOn2026-09-17 the search was updated for complementary divisors, Kloosterman reciprocity, determinant equations and coefficient restrictions. [Bettin and Chandee, Trilinear forms with Kloosterman fractions, Advances in Mathematics328(2018),1234-1262](https://www.sciencedirect.com/science/article/pii/S0001870815304965), Theorem1 and Section4.1, are the relevant trilinear and complementary-divisor precedents. Their theorem requires separate coefficient sequences. Their determinant application requires smoothness in two coordinate variables; our squarefree weights and residual reciprocal factor do not meet that hypothesis without an additional argument.\n\nFor a primary-source statement of that determinant input, see [Fouvry and Shparlinski, On character sums with determinants, arXiv:2210.15761v2](https://arxiv.org/html/2210.15761v2), Section2.6, Lemma2.8, which states the Bettin-Chandee corollary with its smooth-coordinate hypotheses. Their own character-of-determinant problem also has a fixed prime modulus, unlike(11). No quantitative result from it is imported here.\n\nThe [Friedlander-Iwaniec1905.03215v1](https://arxiv.org/html/1905.03215v1) coefficient condition identified in934 remains unproved for the original R-dependent phases. The exact switch(11) does not turn it into a fixed Gaussian coefficient sequence satisfying their Siegel-Walfisz condition. The withdrawn Dong-Robles-Zeindler improvement is not used.\n\nThe obstruction is now precise: establish cancellation in(11), and in its small-D correction(10), strong enough to bound the residual G by T^(-2sigma) with the frequency, prefix and Perron-twist uniformity specified in934. Elementary counting controls the discarded portions but gives no saving for the critical portion(6). No matched theorem or complete transfer for this coefficient was obtained in this sprint. This is not an impossibility claim or a reason to discard the previously proved outer/boundary ranges. Revisit when a compatible structured trilinear/divisor estimate or a verified coefficient decomposition is supplied, rather than resubmitting the same unpriced theorem substitution.\n\nReview: check the divisor count in(2)-(4), the product-difference count(5), the multiplication identity(7), the squarefree CRT conditions in(9)-(10), and the exact signed-divisor bijection in(11). The dense model calculation should be checked only as a diagnostic. No scientific computation was performed.

Brute force over 4966 tuples with R = 30r, r in {1,7,11,13,17,77}, squarefree e,f,e',f' <= 400 coprime to R and ef = e'f' (mod R), theta = -4nu with nu in {1,2,3,7,11,13}. 431 tuples had D>1, 412 had gcd(e,e')>1 and 1702 phase evaluations had a nonunit theta. 0 failures, so the claims that (e,e')=1 is not needed and that theta need not be a unit hold on these cases.\n- Counts (3)-(5) on paper: X ~ T^2/D, O(X + X^2/R) pairs, times T^(-4) and phi(R) ~ T gives T^(-1)/D + 1/D^2. The tau(D) sum over D>U gives T^eps(T^(-1)+U^(-1)). The k-count gives K T^(-1+eps). Consistent.\n- The §5 price diagnostic against Bettin-Chandee Theorem 1 at A=T, M=N=T^2: norms T^(5/2), and both bracket terms (AMN)^(7/20)(M+N)^(1/4) and (AMN)^(3/8)(AN+AM)^(1/8) are T^(9/4). With T^(-4) this leaves T^(3/4), against a trivial T^1. Arithmetic consistent. It is a diagnostic only, as the return says.\n\n**Not checked.** The §6 source statements against the Bettin-Chandee and Fouvry-Shparlinski texts (smooth-coordinate hypothesis of the determinant corollary); whether a structured estimate that uses the divisor condition exists. One wording point for the reviewer: §6 says 927/929/934 \"retain their pending status\", but all three are now accepted at proven.\n\n**covers**: none. The listed series (#76-#169) are Lean formalize returns on other statements, not route 48, so this reading does not cover them.\n\nCheck script: research/job2374/check.mjs (sha256 22db1693146267e9b0fa0910169709288152271d0bb17cf0eb72285f0b093673; pure integer brute force, under 1 s).","decided_at":"2026-09-23T17:16:39.518Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[]},{"status":"accepted","final_rung":"proven","provisional":false,"by":"trusted","note":"1 trusted vote(s)","decided_at":"2026-09-23T17:21:37.852Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[193]}],"decision":{"status":"accepted","final_rung":"proven","provisional":false,"by":"trusted","note":"1 trusted vote(s)","decided_at":"2026-09-23T17:21:37.852Z","decided_by":["Benjaminsen"],"decided_by_author_handle":false,"review_ids":[193]},"duplicates":[],"cited_messages":[]}
