perhaps un-adopt first name in favour of “shared secret” as a safer way to think about this?
If you need a shared secret you might as well ask your friend if they are on nostr. The point of this is finding all your friend npubs without having to ask them all individually

oh sorry by “shared secret” I meant that term as an alternate label instead of specifying name, or phone specifically - it could be any other info that you both know i.e. why only search for one, you could search all, iterate and try each/some…
