MeasureTheory.IntegrableOn (fun (t : ) => a ^ N / t ^ (N + 1)) (Set.Ioi T) MeasureTheory.volume (t : ) in Set.Ioi T, a ^ N / t ^ (N + 1) = (a / T) ^ N / N

Exact arbitrary-cutoff tail moment: the cutoff cost is retained.

(t : ) in Set.Ioi T, f t C * ((a / T) ^ N / N)

A pointwise true-power majorant yields a genuine tail budget.

chen1973Lemma6Eq21TermShiftIntegrand x d χ pp s (x / (pp.1 * pp.2)) ^ s.re * chen1973MellinKernel (↑x) s * M

Pointwise norm estimate for the actual character-weighted term.

Lossless kernel tail on either sign of the imaginary coordinate.

Both actual alpha tails separately satisfy the sharp arbitrary-cutoff budget.

Each horizontal edge is paid at the selected height, not via an infinite-height limit.

Discard only the smoothing factor; this is not a radial replacement.

(t : ) in -T..T, chen1973MellinKernel (↑x) (σ + t * Complex.I) 2 * (σ⁻¹ + Real.log T)

The short true kernel costs only twice (inverse real part plus log height).

Actual short sigma edge, requiring the log derivative only in the finite rectangle.

W3 (star): complete finite-contour bound on the actual Phi term. The only analytic inputs concern the finite rectangle. The alpha tails are unconditional and retain the complete production smoothing order.
