Right. So sorry. "Constant" gravitational field. Happy?
But I agree, if you put the box within the event horizon of a black hole (aka near a point mass) the person inside the box might be able to tell, if they and the box were still intact. What I don't agree with is that splitting hairs on the divergence of the gravitational field is productive.
