 * What the transcript says where a session ran out of quota.

 * The pair worth a test is the one that reads the same when it goes wrong: a reset time that
 * arrived and one that never did. The second must not turn into a plausible-looking time, because a
 * reader has no way of telling an invented one from a reported one.
