Martin's initial test cases are wonderful. I've adapted them to test the
other conditions in the verify_commit_graph() method and caught some
interesting behavior in the process. I'm preparing v2 so we can investigate
the direction of the tests.

Cool, I'm glad you found them useful. One thought I had was that you
could possibly write the tests such that you introduce errors from the
back of the file. That might enable you to do less of the "backup
commit-graph file and restore it"-dance. Just a thought.
