We still need to decide how we will handle Exceptions in case of a recheck or changing values -- and, of course, implement it.
show exceptions on Special Page Cross-check (not as new violation)
- sort by status (Violation, Exception, Partial Match, Match)
- show 'Mark as Exception' on Special Pages Cross-check and Constraint Report [blocked by migration of constraints]
- show exceptions in API
- save exceptions of constraints in violation table
