Predict dumping (#32394)

* Predict dumping

- This got soaped really fucking hard.
- Dumping is predicted, this required disposals to be predicte.d
- Disposals required mailing (because it's tightly coupled), and a smidge of other content systems.
- I also had to fix a compnetworkgenerator issue at the same time so it wouldn't mispredict.
