```
planning.runningSession(server: : Server, name: : string) -> Promise<Session | undefined>
```

The session this workspace names, on a server that may not be running yet.

Acquisition raises on an unreachable server rather than reading as empty,
which is the answer a caller asking what is there needs. Building from
nothing is the ordinary starting point here, though, and a socket with no
daemon behind it is holding this session in the way an empty server is: not
at all.
