```
get(Server, Id)
-spec get(tmux_server:t(), tmux_model:session_id()) ->
             {ok, tmux_model:session()} | {error, map()}.
```

Read fresh session fields through explicit one-shot commands. The session ID is stable within the observed server incarnation. Returns target_gone when tmux no longer has that session; it never refreshes an existing record.

## Parameters

- `Server` (`tmux_server:t()`)
- `Id` (`tmux_model:session_id()`)

## In other ports
