And if you want passive discovery, NIP-66 relay self-announcement (kind:30166) is the newer mechanism — your relay publishes its own meas...

Worth separating the relay side from the discoverability side. On relays: publish a NIP-65 list (kind 10002) so clients know where to look for you, and keep at least one well-connected relay in your write set, otherwise your notes only exist on the relays you post to and nobody's client is querying ...
