```
start(Server, Command, Options)
-spec start(tmux_server:t(),
            tmux_command:t(),
            tmux_server:command_options()) ->
               {ok, t()} | {error, failure()}.
```

Submit a validated command under the endpoint's admission limits and return an operation handle. The initiating process owns it. Submission is non-blocking with respect to command completion; the handle does not prove that tmux has executed the command.

## Parameters

- `Server` (`tmux_server:t()`)
- `Command` (`tmux_command:t()`)
- `Options` (`tmux_server:command_options()`)
