 ## Open questions / TODOs
 
-- [ ] Live-test against Libera (join `#r.trees`, exercise commands). Not yet run.
+- [ ] Exercise the `!` commands live in-channel (connect + join verified; command
+      round-trip not yet tested with a second client).
 - [ ] Decide whether `!delquote` should be restricted to ops/admins (currently
       anyone can delete). Fine for a trusted channel; revisit if abused.
-- [ ] Consider registering the `treesquotes` nick with NickServ if the channel
-      blocks unregistered users.

+## Resolved

+- `#r.trees` is `+r` (registered-nicks-only). Nick `treesquotes` is registered &
+  NickServ-verified under megaproxy@gmail.com. Password lives in gitignored
+  `config.env` (`IRC_NICKSERV_PASS`). Bot identifies and joins successfully.
