It would seem that they both must observe the laws of General Relativity.
So one answer to your question is that nothing comes out of the black hole at all. No gravitons move from the black hole to the outside world.
So if no gravitons move from the black hole, how does gravity work from there?

Graviton is a hypothetical particle in theory of quantum gravity. General Relativity says nothing about gravitons. GR rather describes spacetime as continuum.
So what you saying is that there is "graviniferous ether" for gravitons?

A black hole's gravitational field is frozen in place, so nothing has to escape it to make its field. Changes in it are a different story, however.
So you saying that gravitons eminate from mass within the black hole, but those are subject to GR, and so stay within the black hole? I wonder if the gravity waves on the return back (i.e., like an ICBM coming down after reaching maximum altitude within the Earth gravity well) somehow reinforce each other in some type of resonance.A black hole's gravitational field is frozen in place, so nothing has to escape it to make its field.

As to gravitons, gravitational waves will propagate like electromagnetic ones, and will be unable to escape from inside the BH's event horizon.
Gravitons are not part of general relativity. General relativity ignores quantum theory and the graviton is a purely quantum particle.It would seem that they both must observe the laws of General Relativity.
In the absence of a full quantum theory of gravity, we can quantize perturbations of a classical-limit gravitational field. Even without that, we can work with such perturbations in the classical limit. One finds that they travel on null geodesics, just like photons. This means that if a gravitational wave originates inside a black hole's event horizon, then it will not escape.
Yes, but then the background spacetime is not composed of gravitons since the “gravitons” are perturbations. In other words, a static black hole is not producing its gravity by emitting a stream of gravitons in such an approach.In the absence of a full quantum theory of gravity, we can quantize perturbations of a classical-limit gravitational field.
As you may know, the only grav-waves detected up today have been originated outside black holes, and neutron star collisions, both from the dissipated energy of their movements, and consequently their gravitatory effects on the spàce-time geometry.A black hole's gravitational field is frozen in place, so nothing has to escape it to make its field.
