Finite generation of the maximal everywhere-unramified pro-p Galois group

The power--commutator quotient of the maximal everywhere-unramified pro-p Galois group is the finite Galois group of the elementary Hilbert layer. A finite set of lifts of that quotient topologically generates the full group.
