For better or worse, the current state includes a lot of noisy "fixing
tests" type commits which I
would like to automatically skip over when hunting bugs. This is not
great and is being addressed,
but I am trying to make the most of the historical data we have today
- which does contain tags
for all builds that passed automated testing etc but does not have
only good commits on the related
branch.

I can see how this would work, but only for future builds. I would need something like it but loop over all existing tags as this is a problem with historical data. Could you please be more specific as to the steps required to automatically form a commit that represents the change between two commits (i.e. tags)?
