I would expect there to be a way to get the user's pubkey from a sha256, but I can't find it...

OK, I'll answer it myself, after looking at blossom-server-sdk... I understood. Of course there is no way. Because the same blob can belong to more than one user.

yes a single sha256 could belong to multiple users. a good example of this would be the bitcoin white paper which is b1674191a88ec5cdd733e4240a81803105dc412d6c6708d53ab94fc248f4f553

As for finding users servers, that can be done with the 10063 event kind in https://github.com/hzrd149/blossom/blob/master/Nostr.md
