My bet is now on AF-assist pulses from the onboard flash.

Wouldn't the AF assist require that two cameras were in play at the time? One camera wouldn't fire the AF assist while the shutter is open unless it's faulty.

Right. To get AF-assist you need to be in One-Shot, but if you're in One-Shot you can't open the shutter without focus confirmation, and AF-assist stops when focus is confirmed.
