Query: Taming boundary condition changing operator anomalies with the tachyon
  vacuum   Motivated by the appearance of associativity anomalies in the context of
superstring field theory, we give a generalized solution built from boundary
condition changing operators which can be associated to a generic tachyon
vacuum in the $KBc$ subalgebra of the Okawa form. We articulate sufficient
conditions on the choice of tachyon vacuum to ensure that ambiguous products do
not appear in the equations of motion.
