Superdirectivity as a Spectral-Collision RKHS Limit
Superdirectivity is the spectral-collision limit in RKHS where array gain equals the reproducing kernel diagonal and the M squared endfire law arises from endpoint asymptotics of the Christoffel-Darboux kernel, with Christoffel collapse at the hard edge M times faster than interior under flat L2 geo
