I figured out my problem, now how do I fix it? A/F OSCILLATION

The rough MAF signal you're seeing is the sensor reacting to the air going in different directions. There's nothing wrong with the sensor. It's reporting exactly what it's seeing.

That's right, and it was what I was getting at. Seems to me as evidence that a screen will probably help. Reversion shouldn't be happening up above 1200rpm, yet the signal is still rough.

Just to clarify I don't think a screen will prevent reversion. I think the MAF is reading turbulent airflow - air going in different directions.

The honeycomb in MAF sensors were designed to straighten the air ENTERING the MAF. They weren't designed or meant to prevent reversion.

A very long time ago (2011 or so) I had a customer with stock C6 Corvette having very unstable MAF signal while cruising. It did run very nicely when forcing at SD but being stock I didn't want to tune it but just send him back to the dealer.
