I agree with 30mph. I do believe that is what the owners manual states as the minimum speed.

Unfortunately, I don't recall if I put the transmission in park or if I kept my foot on the brake. I'm inclined to think that I put it in park. Like you, I've never observed a halted regen at a stoplight. It would be an interesting experiment to stop and leave the truck in gear during a regen to see what happens. Perhaps I'll try that the next time a regen starts right as I'm pulling into my neighborhood.

With the CTS you will also notice that active regen starts up to one minute before the dash notification message appears.

Thanks Matt and kepr005 for info to monitor on the Edge CTS.
