    Sharp LS is freshly applied to each shell; its length is H*2^j, not H². The upper bound pays the shell's own weighted energy.

    The genuine finite polynomial term of (14), on every vertical line Re(s) ≥ 1. The fifth logarithm is the dyadic Cauchy cost; four logarithms come from the globally recombined harmonic divisor-square energy. This theorem does not assert the full printed equation (14): its L-function truncation remainder is deliberately absent.
