While being manifestly superconformal, our boundary states are not a priori required to satisfy the usual free-field gluing conditions along the internal directions of the 4-tori. Our calculations proceed along the lines of Gepner's construction by recasting the $\\mathcal{N}=(2,2)$ worldsheet sigma model on the 4-tori in terms of $\\mathcal{N}=2$ minimal models.
