  The first two sections of the paper provide a convenient scheme and
additional diagrammatics for working with Frobenius extensions responsible for
key flavors of equivariant SL(2) link homology theories. The goal is to clarify
some basic structures in the theory and propose a setup to work over
sufficiently non-degenerate base rings. The third section works out two related
SL(2) evaluations for seamed surfaces.
