An n6k catalog is a real DuckDB catalog served over a WebSocket. Any DuckDB — a terminal, a notebook, a Go service, a browser tab — canATTACH it and query it with ordinary SQL, alongside its own local tables and files. These pages are the client side: how to attach, how to authenticate, and what travels over the wire.
