mock.Failures already made a method fail on every call. FailurePlan adds the call numbers, which is the shape of nearly every device fault the runner has to survive: the first read times out, the next one works. Expressing that by embedding the mock in a one-off wrapper put a different seven-line method in every test that needed one.
