Man, we have a lot of branches going on here! Let's rebase all the work from these branches onto master.
Upper management is making this a bit trickier though -- they want the commits to all be in sequential order. So this means that our final tree should have C7' at the bottom, C6' above that, and so on, all in order.
If you mess up along the way, feel free to use
resetto start over again.
