"Justice delayed is justice denied." It's unlikely that it could exceed 24 hours and if it exceeded a couple of hours you could get a preliminary injunction (unfortunately of course you'd need counsel to know about the detention in order to act on your behalf). As a practical matter, more senior officials at CBP should hopefully know about their limitations and if you request counsel and stay silent then they'd likely release you.
