Hi! It seems that this topic is not clearly explained in the docs (forgive me if I missed it) or anywhere in internet. I wonder what happens to files after they are deleted in GrapheneOS and the possibility to recover them.

Let's imagine a situation. A person takes a picture, logs in an account using Vanadium, sends a picture, and deletes all Vanadium history and the photo. Then, they install an app, do something there, and delete it (along with any remaining files in the Files built-in app).

But in an hour they are caught by some 'bad guys' who force them to unlock the phone. What can they recover from the aforementioned activity? If something is recoverable, is it possible to somehow prevent it? Or are we left hoping to enter the duress password in time or misguide the adversary to do it?
