Yes, we will probably write a more detailed paper about this, and
it should part of Albin Coquereau's Thesis.

Roughly speaking, we (dynamically) filter the model constructed
by the CDCL SAT solver to only keep the facts which satisfy a
branch that would be constructed by the Tableaux method. This
reduced model is then used to check satisfiabily modulo theories
and to generate new instances by E-matching.

This is somehow similar to what is described in this Z3 tech. report:
