The nick rule moves from internal/handlers to internal/service as ValidNick, and the HTTP API and both IRC listener NICK paths call it. The IRC listener used to cut a nick to 32 bytes and accept anything else, so a nick with spaces such as "bob PRIVMSG #inj :hi" made the lines built from it read as another user's PRIVMSG. It now answers a nick the rule refuses with ERR_ERRONEUSNICKNAME (432), before and after registration, and keeps the nick as it was. Model: opus-5-5
