Reinterprets the brick-wall model as an effective description of finite-N departures from the semiclassical near-horizon continuum in AdS/CFT, producing residual reflections and model-dependent echoes.
Explicit reconstructions in modified near-horizon AdS2 and BTZ geometries recover prior non-locality estimates controlled by a throat parameter and exhibit dip-ramp-plateau spectral form factors in 3D.
