Lorentzian-Euclidean black holes produce excess inner-shadow intensity and accumulate energy at the horizon with backreaction unlike stable light rings.
Black mirror spacetime has no surface layer or impulsive gravitational wave singularity at the horizon and permits direct connection between exterior regions.
