> I came across this scenario where ksck reports the tablet has mismatched consensus and configs disagree with the master's but they do not seem to be:
> The consensus matrix is:
> Config source | Replicas | Current term | Config index | Committed?
> ---------------+--------------+--------------+--------------+------------
> master | A B* C | | | Yes
> A | A B* C | 2939 | 20571 | Yes
