 In reading our Sponsor S quarterly report draft, I found a section about
 how our unit test coverage is up to 37%, and our stem+chutney test
 coverage is up to 62%.

 Great. What were they before, and what is their rate of change?

 Is this the sort of thing where we have the numbers somewhere? Is it easy
 to automate over time?

 Ideally we should even arrange things so the graphs can help *us* in some
 way too -- first by e.g. giving somebody a sense of satisfaction when a
 big branch gets merged and the coverage line shoots up a lot, but then
 next by helping us notice when some *other* big branch gets merged that
 suddenly undermines coverage in a way we didn't expect? Let's not do this
 to satisfy a funder -- let's figure out a way where tracking and
 visualizing our progress helps us make progress better.
