-spec launch(launch_spec()) ->
                {ok, [binary()]} | {error, map()}.
```

Render explicit executable argv, an explicitly requested shell command, or default_shell. Singleton argv uses the installed helper's exec-only mode to avoid tmux interpreting it as shell syntax. Performs no I/O.

## Parameters

- `Argument1` (`launch_spec()`)
