I. The documentation on Project vs. Repo permissions is poor. I understand that you guys want to keep this simple, but this doesn't give me enough information to predict what combinations of Project (P) and Repo (R) permissions will do:
In particular there's nothing about whether repo permissions override project permissions or vice versa. This should be made VERY clear in the docs. The only place I see it listed is in the one sentence at the top of the repo permissions screen, but some example in the docs would be really useful.
