Also that the file had to be "recovered" which could indicate that while there's an Exarch, there might not necessarily be a Terra like we know it. Its also called a Draft, which means it might not have been finalized, meaning whatever happens to Terra could be rather close to the 3150 date that its written. We also know that apparently the Clans, or atleast in this case the Loremaster is fine with calling the Wolverines "Wolverines" and not "The not-named." And we also know that the Gunslinger that recovered the file is named Eli Sender. Sender is a Bloodname that was originally Widowmaker, then exclusively Wolf for a while, and then after the WoR became shared by the Wolves, Diamond Sharks, Snow Ravens and Jade Falcons. And yes, its possible that the name is a coincidence of course.
And the final bit, is that we know Eli Sender, who recovered the document felt the need to comment on the Minnesota Tribe section (the only place he did), and that his comment was redacted.
