I am not claiming that I know the code well en, so take my comments with a grain of salt. If signing is done at the client and key is never known to nsecbunker in its plain form, then only client has the access, if not, then server has the access. nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft will be able to confirm one or the other way. 🐶🐾🫡
