adding remarks on objects to C.1; this is pretty uninspired writing, so feel free to improve

+the nontrivial spin homeomorphism from $B^1$ to itself which covers the identity
 gives an order 2 automorphism of $c(\cX)^1$.
+There is a similar involution on the objects $c(\cX)^0$.

 For 1-categories based on $\text{Pin}_+$ balls,
 we have an order 2 antiautomorphism and also an order 2 automorphism of $c(\cX)^1$,
 and these two maps commute with each other.

+In both cases there is a similar map on objects.
