3. If stabilizer runs airplane nose down again, recognize it as inappropriate and arrest by using manual pitch trim to stop MCAS stabilizer motion and move stabilizer back to trimmed position. (No need to sit idly by and watch 10 seconds of stabilizer motion taking you away from trim go in when you have determined that is not appropriate.)
4. Call for PNF to toggle stabilizer cutout switches and discuss managing pitch trim via manual trim wheel for the balance of this flight.
5. Make sure that this event is squawked in a manner that assures:
- The source of the errant stabilizer motion is identified and corrected prior to the next flight
- The next crew to fly this bird knows full well what was encountered on this flight and what was done to work around it.
You may well believe it's that simple. There are plenty of distractions in the real world from ATC, terrain, weather/turbulence etc. That's before the stick shaker activates and the autopilot disconnects. Whilst you are trying to work out why that has happened (because it could be a variety of reasons) and fly the aircraft (including trimming), the aircraft is working against you. And this aircraft trims automatically on every departure, often against you.

Sat typing at a keyboard it appears obvious. All pilots will be able to tell you the memory items.
