This is an important point. But I’d say not. Constraint checks are there to make sure that the programmers are doing the Right Thing, not that the DBMS is doing the Right Thing. So it’s the source value which is checked, not the value stored in the database. To do it the other way around suggests that SQLite needs to check that SQLite is doing the Right Thing, which would be a waste of cycles, and a sign that the developers need to consult a psychiatrist.
