should list the exit policy matching the descriptor digest referenced
in the consensus document.
3.4.1 Client behaviour
When choosing an exit node for a specific request a Tor client will
choose from the list of nodes that exit to the requested port as given
by the consensus document. If a client has additional knowledge (like
cached full descriptors) that indicates the so chosen exit node will
reject the request then it MAY use that knowledge (or not include such
nodes in the selection to begin with). However, clients MUST NOT use
nodes that do not list the port as accepted in the summary (but for
which they know that the node would exit to that address from other
sources, like a cached descriptor).
An exception to this is exit enclave behaviour: A client MAY use the
node at a specific IP address to exit to any port on the same address
even if that node is not listed as exiting to the port in the summary.
