I just tested it.
After the lasso ender in the corner, if WW neutral jumps db3 OR forward jumps instant air db3 it will hit front. And if WW forward jumps db3 it will cross-up. So I believe this mixup is at least reactable offline. But on hit she gets a free 50/50 into the same situation and yes it's a true OTG. Impossible for a human to wake up attack there I'm pretty sure.
After an air meaty db3, I'm 100% sure she is at least +3 on block because Black Adam's 6f d1 trades with her 9f 2. So even if you manage to block air db3 you still have to respect her follow up pressure and you are denied wake up options.
The dash up F3 crosses-up but she can mix it up by holding F3 for a bit or by doing b2/3 mixups instead.
I knew WW had a strong corner game but that's another level of corner lockdown.
