// TODO: we use narrow with first=true to add axioms about the constraint to the solver.
// However, constraints can be activated multiple times (e.g., if it comes from a lemma and is propagated at a non-base level).
// So the same axioms may be added multiple times.
// Maybe separate narrow/activate? And keep a flag in m_bvars to remember whether constraint has already been activated.
