queryCalendar matched on a day word and stepped aside only on weather
wording. Every world question naming a day was claimed by it and answered
with an empty schedule: "какой сегодня курс доллара" replied "на
05.08.2026 ничего нет", which reads as an answer about a subject she
never looked at. All four probe utterances have an answer in search, and
search sits below the calendar.
V-474 fixed one instance of the class. Sunset, holidays, exchange rates
and world news are the same class and weather wording does not cover them.
router.IsAgendaQuestion is the narrowing. Its first arm reuses
AgendaQueryGrammars, so the rule that routes a question to the query
chain and the rule that lets the calendar answer it cannot drift. The
second reads a scheduled-thing noun, wider than the grammars because
"какие встречи завтра" carries no possessive. The third claims a
question that names no subject of its own.
A continuation is exempt: "а завтра?" cannot name an agenda, and this
is the only date-aware source there is.
