```
def acknowledge(
      argv: Seq[String],
      timeout: Duration = Duration.ofSeconds(30)
  ): F[Control.Ack]
```

Reads one raw reply without claiming deferred command completion. Cancellation does not prove that tmux rolled back a dispatched command. The timeout starts after Scala admission; an effect timeout can bound the whole call.

## Parameters

- `argv` (`Seq[String]`)
- `timeout` (`Duration`)
