This paper introduces companion-elliptic kernels, a class that includes the Laplace kernel and is defined by a specific coupling with a companion function. The research proves that for kernels in this class, the drifting field is zero if and only if two probability measures are identical, identifying Gaussian and Matérn kernels as members. The study also addresses potential failures in weak convergence, showing that mass can escape to infinity while the field diminishes, but this failure mode is confined to a specific one-dimensional ray.
