This means your scheme is not generally supposed to protect against root?
I assume yes (since I can think of lots of other holes for root), but you should state that explicitely in the spec since it is a major limitation.
On the other hand it will also allow you to optimize significantly:
In particularly it also means that you can trust the permissions and don't need to check any files which cannot be written by users you don't control.
