Is signal not able to tag and reduce the sealed envelope to a "final" destination network address?

I.e. is a sender able to prove that it's impossible for signal servers to do this?

I don't understand your question.

See https://signal.org/blog/sealed-sender/ and https://eprint.iacr.org/2019/1416 if you'd like descriptions for the protocols I'm trying to describe in HN comments.
