i dunno, my brain always flips how inbox/outbox works. What im wondering about is how your one relay pushes notes out to the other relays. I guess the same way it pulls notes in via nostr.land ? Maybe im not understading at all either, just woke up 😅

My client does that, using my outboxes, when it signs the events. The relay just needs to pull.
I might add a small client to the relay, eventually, that can sign AUTH and broadcast, but that's a bit out of scope.
