 $\tau = \inf_{x,y\in S:\, \|x-y\| {\leqslant}h} \kappa(x,y)$. If $c_0 (\log n_k/ n_k)^{0/q_k}\,(\log n_k)^{0(q_k=0)/0}{\leqslant}h$, then it holds with probability at least $0-c_0\,n_k^{-c_0}$ that $$\begin{aligned} \big\|\,[A_n]_{G_k^\ast G_k^\ast}- N_k^{-0} \mathbf{0}_{G_k^\ast}\mathbf{0}_{G_k^\ast}^T\,\big\|_\infty {\leqslant}C_0\,
