They are.
Almost everything on-wiki can be edited by anyone. Do we let people edit one another's judgments? What would that even mean, data-wise?
I've been thinking that judgments can be amended by their creator, but what that does is rank=deprecated the old judgment and creates a new one. I want that data either way, but we can save the old history into a secondary store that cares about slow-changing dimension if needed.
That's a good question. I think only admins should be able to "make edits" by hiding endorsements. This is roughly similar to the pattern of revisions and suppression.
+1 for saving the data in a secondary store. I think it's a good idea to have this secondary store anyway. Any real contribution interface for JADE will want that history, but JADE itself only needs to know the current state to validate an action/event.
