As can be seen by Understanding Page History this can be complex, containing differing view points - and maybe realities.
Forking as (cultural) feature raised issues of identity and provenance. <p> We can see that frances.uk.fedwikihappening.net created the page and directory.fedwikihappening.net forked it, adding commentary. Finding out that frances is Frances Bell, or that directory.fedwikihappings.net is Mike Caulfield, is Discoverable but not Obvious. <p> FedWiki's neighborhood boundaries are vague and dynamic. But everybody owns their stuff in this network. When should that ownership be more, or less, obvious?

Mike Caulfield: Jon, I like this experiment. Of course we'll end up with many different talk pages with 90% overlap, but I think that's OK. I tend to think of conversation here as being like Twitter where it's fine if you see only a portion of the conversation. Forking will always allow you to see what an individual is responding to on a page, which is the main thing.
Identity and citation has to be discoverable -- that's part of the deal, the BY in the CC-BY-SA. But it does not follow that citation should be obvious. In fact, there are many reasons to to background citation.
