```
open(Options)
-spec open(open_options()) -> {ok, t()} | {error, map()}.
```

Open a borrowed socket endpoint and start its supervised library owner. The caller owns that handle. This probes the executable, daemon version and observed Linux process incarnation; it never starts a tmux server or attaches a control client. Pass an absolute socket_path and optionally an executable.

## Parameters

- `Options` (`open_options()`)
