 \paragraph{Picking the resources.}
 The key ingredient that we will employ on top of the base logic is to give some more fixed structure to the resources.
-To instantiate the logic with dynamic higher-order ghost state, the user picks a family of locally contractive bifunctors $(\iFunc_i : \OFEs^\op \times \OFEs \to \CMRAs)_{i \in \mathcal{I}}$.
+To instantiate the logic with dynamic higher-order ghost state, the user picks a family of locally contractive bifunctors $(\iFunc_i : \COFEs^\op \times \COFEs \to \CMRAs)_{i \in \mathcal{I}}$.
 (This is in contrast to the base logic, where the user picks a single, fixed camera that has a unit.)
 
 From this, we construct the bifunctor defining the overall resources as follows:
