Re: dependency pinning, I put together a little write-up about that: https://gist.github.com/MatrixManAtYrService/6eaf50373448c0b...

You can use it as an alternative to `git bisect` where only you're only bisecting the history of a single subflake. I imagine writing a new test that indicates the presence of an old bug, and then going back in time to see when the bug was reintroduced. With git bisect, going back in time means your new test goes away too.
