## Overview

### Impact

I can convince the UI to let me do things with an invalid Application.
1. Admin gives me `p, michael, applications, *, demo/*, allow`, where `demo` can just deploy to the `demo` namespace
2. Admin gives me AppProject `dev` which reconciles from ns `dev-apps`
3. Admin gives me `p, michael, applications, sync, dev/*, allow`, i.e. no updating via the UI allowed, gitops-only
4. I create an Application called `pwn` in `dev-apps` with project dev and sync the app with sources from git
5. I change the Application’s project to demo via kubectl or gitops (whichever mechanism my admins have given me, because it should be safe)
6. I use the UI to edit the resource which should only be mutable via gitops
