There's nothing clean about the history. You think commits like [0], with the commit message "improve", count as "clean"? What do you think the motivation for the author would be to modify git history to make it appear that this was written over a weekend, including separating each feature/commit by a few hours, which corresponds to a reasonable amount of time that it may have taken to write that feature? Including a break on Mar 15 at 1:18 AM PDT before continuing to commit at Mar 15 at 12:43 PM PDT. Hey, isn't there a normal human behaviour that occurs around this time every day which takes 6-10 hours?

I'm fully aware you can rewrite git history to whatever you want, but this is an occam's razor situation here. You'd only think this wasn't a weekend project if you desperately wanted to believe that this was some major initiative for some reason.
