Assume ZetaSeam — the package of classical facts (finite order at each zero, invariance of the zero set and multiplicities under $\rho \mapsto 1 - \bar\rho$ , local finiteness) that realises the nontrivial zeros of $\zeta$ with multiplicities $m_\rho$ (zeroMult) as a zero configuration zetaZeros hs. Let $k$ be $C^2$ with compact support and $H = H_k$ its analytic weight (Hfn k). Let $R_j$ be any sequence of heights with $j + 7 \le R_j \le j + 8$ , and let $Z_j$ be finite sets whose members are exactly the nontrivial zeros $\rho$ with $-R_j < \operatorname{Im} \rho < R_j$ .

Statement. As $j \to \infty$ ,

\sum_{\rho \in Z_j} m_\rho\, H(\rho) \;\longrightarrow\; \sum_{\rho}{}' \; m_\rho\, H(\rho),

where the limit is the tsum over all distinct nontrivial zeros (the carrier of zetaZeros hs). The truncation windows increase and exhaust the zero set, and the full sum converges absolutely (EF_zero_sum_summable), so the finite sums appearing in the rectangle identity at heights $\pm R_j$ tend to the complete zero side.

Role. In the module Zeta23.WeilEF.ZeroSumLimit this is the zero-side limit consumed by full_line_identity in Zeta23.WeilEF.FullLine, completing the passage from finite rectangles to the full explicit formula.
