What should the function be called? It is currently referred as "Constraint violation" but that term has various problems imho:
- "Constraint" may suggest that there is a clear boundary, and if that is stepped over it is always a bad thing (but the checking code can be wrong, too!)
- "Violation" may suggest again that bad things happened like a technical problem that will occur or anger in the community will be the result.
So the frame is negative and maybe even threatening.
Another framing could he that of helpful hints that encourage the user to either improve the data on wikidata or the constraints. Which could lead to:
"Data checks", "Constraint checks", "constraint hints" or so.
