AP-normalized direct Type-II bilinear shells #

The direct mean is formed before squaring. Cauchy is first taken over primitive characters and then over moduli with the outer weight q⁻¹/²; hence the square side has exactly the q / φ(q) weight accepted by the bilinear tensor large sieve. The canonical (d,t) tensor prefix remains intact throughout.

The resulting square scale on a d-shell is

H * RM² * D * (M + c(Q)Q²) * E(D,M).

For the actual tensor energy E(D,M) ≪ D M log⁵, taking the square root gives D M + sqrt(c(Q)) Q sqrt(D * D M), rather than another unsquared factor D M. Thus the existing second moment is sufficient for the direct shell. The final theorem below only aggregates already-physical shell bounds; it does not freeze a Type-II conclusion as a new analytic premise.

The unsquared AP-normalized mean of one actual canonical (d,t) tensor prefix. The maximum in t is inside each primitive-character summand.

    The correct double Cauchy inequality for a direct bilinear shell. Character Cauchy is local to each modulus; modulus Cauchy uses q⁻¹/². Consequently no cardinality factor for the modulus interval and no second tensor energy appear.

    Fully explicit direct-shell square bound. In contrast with applying an additional rowwise estimate after Cauchy, the 27 tensor energy is multiplied only once.

    Scalar physical-scale extraction from the square ledger. If X = D*M ≤ y, then the polynomial part of the direct shell is bounded by y + sqrt(c) Q sqrt(D*y). This is the point at which the apparent extra D*M is removed by taking the square root.

    Honest final wiring: once the exact canonical shell decomposition and its physical bounds have been proved, their finite sum inhabits the existing AP-normalized Type-II input. No Type-II estimate is assumed under another name.
