// All unfolding event objects are created in reference to
// an Unfolding object which owns them. Hence, the references
- // they contain to other events in the unvolding can
+ // they contain to other events in the unfolding can
// be used as intrinsic identities (i.e. we don't need to
// recursively check if each of our causes has a `==` in
// the other event's causes)
