...
mbp_qel uses two iterations of saturation.
The first iteration uses only congruences, not the model.
The second iteration uses the model.
Terms are marked as "seen" during either iteration and will not be reprocessed if they are "seen".
All select terms get marked as "seen" to avoid reproducing Ackerman axioms.
But this conflicts with expanding select-store axioms during
the phase of saturation where use_model is allowed.
