  Vacuum spherically symmetric loop quantum gravity in the midi-superspace
approximation using inhomogeneous horizon-penetrating slices has been studied
for a decade, and it has been noted that the singularity is eliminated. It is
replaced by a region of high curvature and potentially large quantum
fluctuations. It was recently pointed out that the effective semiclassical
metric implies the existence of a shell of effective matter which violates
energy conditions in regions where the curvature is largest. Here we propose an
alternative way of treating the problem that is free from the shells. The
ambiguity in the treatment is related with the existence of new observables in
the quantum theory that characterize the area excitations, and how the
counterpart of diffeomorphisms in the discrete quantum theory is mapped to the
continuum semi-classical picture. The resulting space-time in the high
curvature region inside the horizon is approximated by a metric of the type of
the Simpson--Visser wormhole and it connects the black hole interior to a white
hole in a smooth manner.
