The scalar-sourced slot, recorded

The named target of this paper is ${{\Phi }^{(2)}}_{\mathrm{D}}$. The scalar-sourced slot is recorded so that the word “complete” has a definite meaning: the second slot of Proposition prop:gfcoeff is $r_{\mathrm{D}}+r_g$, both summands are admitted, and only $r_{\mathrm{D}}$ varies under the metric shift.
