Whether a dismiss stamped at dismissedAt still covers the reply posted
at lastResponseAt: both parse and the dismiss is not older than the
reply. A reply newer than the dismiss resurfaces the issue, so the daily
run and the dashboard must agree on this one comparison (#1862). An
unreadable stamp fails open (not covered), matching the daily run's
dismiss filter.
