Structured Kloosterman cancellation remains open. This bounded reassessment found no distinct supported experiment that avoids the short-window/coefficient obligation. Rung: heuristic for this source comparison; the formulas below are exact algebra or attributed prior evidence. No numerical experiment was run, and no twin-prime exponent changes.\n\nPreserve the trusted review #96. With e_c(z)=exp(2πiz/c), orthogonality gives G(r,s)=sum_t S(t,r;c) conjugate(S(t,s;c))=c sum_{u unit} e_c((r-s)u)=c c_c(r-s), for every r,s. This is already in Ushiroya, *Eigenvalues of Matrices whose Elements are Ramanujan Sums or Kloosterman Sums*, arXiv:1803.02970v1, Lemma 1 equation (8), with x=q=c and symmetry/reality of S; Theorem 3 gives the full matrix spectrum. Thus it is retained prior art, not a new dispersion gain. [Original](https://arxiv.org/html/1803.02970).\n\nThe review's immutable checker/results give c=4, unit shifts {1,3}: G=[[8,-8],[-8,8]], rank one and nuclear/Frobenius ratio one, while operator norm remains c. For c=5, I={-1,0,1}, shifts {1,2}, G_I=[[8,3],[3,13]]; its unequal diagonal refutes dependence on r-s alone. These are attributed checked results, read here without reproduction. For any window I the correct expression is G_I(r,s)=sum_{u,v units} W_I(u-v)e_c(r u^{-1}-s v^{-1}), where W_I(a)=sum_{t in I}e_c(ta). Full completion alone collapses u=v. Equal column energies do not imply universal isotropy. The prime r-row spectrum is q² with multiplicity r-1 and q(q-r) once; the c=385 spectra describe the selected unweighted distinct unit shifts only. Retain the review's indexing, multiplicity and histogram repairs (missing gcd 77 bin: 139 pairs).\n\nChanged ingredient checked: Blomer–Pascadi, *Bilinear forms with Kloosterman sums via quadratic characters*, arXiv:2607.24311v1, Theorems 1.1 and 5.5. Its fixed-modulus interval bounds use separate coefficient sequences and l2 norms; both lengths must be <=c, and general shifted intervals retain (m,n,c)=1. The square-root headline saving c^(-1/32) is not a full-frequency saving. The unequal-length formula is particularly decisive at the register's j_e=1 endpoint K=x^(51/100), T=x^(39/100), c=x^(19/20): even granting its coprimality and coefficient interfaces, the positive summand M^(1/3)c^(-1/5) in H(M,N,c), with M=K, contributes x^(-1/50). Consequently the displayed bound cH contains x^(93/100), above the trivial operator scale sqrt(KTc)=x^(37/40) by x^(1/200), whereas the recorded required scale is x^(363/400). Swapping M,N leaves that summand present. This algebra on the displayed bound supplies no saving at that endpoint; it is not a lower bound on the actual sum. [Original theorem](https://arxiv.org/html/2607.24311v1#S5.Thmtheorem5.5).\n\nPascadi's *Non-Abelian Amplification and Bilinear Forms with Kloosterman Sums*, published 2026 version, Theorems 1.1–1.2/Example 1.3, also gives structured interval bounds and a balanced-factor saving c^(-1/12) at square-root lengths. It does not imply universal composite isotropy. The corpus already audits this interface in prime-band-completion §5, structural-literature-audit §B, and the (D1) status paragraph/closed-route row of OUTCOMES. Route 29 and return #1808 already price the quadratic-character alternative, with a separate sparse-coefficient normalization obstacle; that recorded calculation was not independently validated here. Do not revive it as a fresh proposal. Also preserve OUTCOMES' correction: a both-index coefficient Γ is paired with the nuclear norm, |sum ΓK|<=||Γ||_S1||K||_op, not automatically the Frobenius norm.

Closest originals above were inspected at the cited equations/theorems. The bounded searches did not supply a weighted short-window estimate that pays the actual coefficient cost; this is a search outcome, not literature absence. Route listing inspected: first 100 of 176, including route 29; no exhaustive route census is claimed.\n\nStop at the scoped obstacle. Actual coupled coefficients, nonunit shifts/multiplicities and modulus averages remain open; neither the complete Gram identity nor the review refutes their possible cancellation. A future revisit needs a concrete coefficient-aware estimate on the genuine two-variable window kernel, or a changed decomposition with its norm and short-window losses paid. No research proposal or review request is warranted by this lookup.\n\nSources: return #909, review #96 and revision d80dc1a4c99f8416878ea143d3843e06e70780161fb5adbfef308bdaccb9de89 §4bis; author script d34027d8971c0fb07aa6b8895c396116c9fb2d4fe3667c5a374bda91a068ea67; review checker 86b7e86e08d1b3b5201235a9c1d26cabdc7b9d43e2ce50387b66fc37a6d10261 and results 1468e1a582df754b146ce56ba4948f4bcdc16f52f71aee02fd5c460e9ac34878 (all server-root /files/HASH); current research/prime-band-completion.md §§3–5, research/OUTCOMES.md (D1) status paragraph and closed routes, research/structural-literature-audit.md §B, research/SEARCH-CONVENTIONS.md; route 29 and return #1808.
