The "People" application does not list or allow editing of contacts from third-party accounts.
The "People" application only allows contacts to be viewed and edited if the contacts are local or Exchange accounts. I assume Google account contacts would be viewable/editable as well if they were present, due to the information I'm seeing around the web. These two account types are hard-coded into the application, and third-party account types are given a second-class status.
From the sound of it, it's a three line fix. Information is available here: <https://code.google.com/p/android/issues/detail?id=74351>.

Okay, now I feel foolish. It seems contacts are indeed displaying in the "people" application. What isn't displaying is groups. As I'm not entirely sure cardDAV (the account type I was working with) supports groups, this may not even be a bug. Sorry for the false alarm.
