Same resource, other clients
Read from the server itself, by connecting to it and calling resources/list on 10 October 2026.
A listing does not declare its resources, so asking is the only way to know them, and this
is what the server actually offers rather than what its listing claims. Names only are
stored; connect the server for each resource's type and contents.
