 - Connect to multiple IRC networks simultaneously
 - All outbound connections routed through SOCKS5 proxy
+- Stealth connect: registers with a random pronounceable nick and generic identity
+- Probation window: waits 15s after registration to detect K-lines before revealing real nick
 - Persistent message backlog (SQLite) with replay on reconnect
 - Multiple clients can attach to the same network session
 - Password authentication
 - TLS support for IRC server connections
 - Automatic reconnection with exponential backoff

+2. Survives 15s probation (K-line detection)
+3. Switches to your configured nick
+4. Joins configured channels
+5. Clients connect to bouncer, receive backlog replay and channel state
