Some assertions are now too strict
...
If possible, we should set the new constraint to l_true;
and revert most of this change later.
Or we adjust the conflict invariant:
- l_true constraints is the default case as before,
- l_undef constraints are new and justified by some side lemma, but
should be treated by the conflict resolution methods like l_true
constraints,
- l_false constraints are disallowed in the conflict (as before).
