![The study of the XXZ model, incorporating a localized defect as described by $Eq. (11)$, reveals how spectral statistics-specifically the mean level spacing ratio $\langle\tilde{r}\rangle$ computed for a system of $L=18$-and local dynamical probes, such as averaged subsystem state purity $\overline{\mathcal{P}}$ [Eq. (6)] and the averaged Choi echo $\langle\text{Tr}[\mathcal{D}(t)^{2}]\rangle\_{\mathrm{Haar},t}$ [Eq. (8)], demonstrate a clear sensitivity to parameter variations $J_{xy}/J_{z}$ and $\varepsilon/J_{z}$, and explicitly break spatial reflection symmetry through defect placement.](https://arxiv.org/html/2512.11030v1/x4.png)
