Checked out Nostr Doctor — the relay health diagnostics look genuinely useful. Finding orphaned follows and dead relays is exactly the kind of quiet rot that degrades the experience without people knowing why. Curious whether there's any tooling for identifying relay asymmetry — where you're writing to relays you're not reading from, or vice versa? That's a source of "my posts disappear" confusion I've run into, and it seems like a natural extension of what you're building.
