"напомни к двум часам позвонить маме" now reads two o'clock. It read no
time at all, so the reminder reached the daemon with an empty slot and she
asked the open "Когда?" about an hour he had just said.
The word that lost it was "часам", the dative plural of "час". Four sets in
internal/router listed the hour noun and every one of them stopped at
"часу". They are now one lexicon key, hour_units, read by all four through
lexicon.HourUnits and lexicon.IsHourUnit. The minute noun had the same gap
one word over and gets the same treatment in minute_units: "минутам" was
missing everywhere "минут" and "минуты" were present. The slot_value_frame
set no longer lists either noun and appends both, so there is one copy of
each closed class rather than a copy per caller.
Two more sites had to move for the sentence to parse. hourPrepositions knew
"в", "во" and "на" and not "к", and the python dateparser rewrite knew the
same three. Both now read the fifth preposition and the oblique forms of the
hour that follow it.
Fixture unchanged: classifier+hash 27/91 before and after, reach 18/30
before and after, no case moved in either direction.

Russian names a half hour by the hour it is entering, in the genitive, so
"половина восьмого" is 07:30 and never 08:30. Neither date parser read that
shape, so the reminder parsed to nothing.
rewriteHalfPast runs in front of the token pass in SpellOutDigits, so the
python parser and the stub both see "в 7:30". It also reads the contracted
"полвосьмого" and the quarter-to shape "без четверти восемь", which counts
from a cardinal and is 07:45. Minus one is in one place, clockHourBefore, with
twelve rather than zero before one.
Ordinals eleven and twelve added to the lexicon, because a clock reaches them.
Minutes a spoken clock does not use are left alone: a guess here is a missed
dose.
Classifier + onnx over the routing fixture 58/82 to 62/87, three new cases,
none regressed. Python dateparser is not installed on this host, so only the
stub was measured. See docs/evals/2026-08-05-half-past-hours.md.
ruNumerals was a second copy of the number words. It stopped at fifty, had no
oblique forms, and disagreed with lexicon_ru_v1.json about its own members, so
"к семи" was not the hour "в семь" was. The lexicon now carries the oblique
cardinals and numwords.go asks lexicon.Cardinal. "час" and "часу" stay local:
they are the hour noun as often as the number one, and nobody counts "час
яблок".
reminderbody.go built its markers from three inline word lists. Two of them
are new lexicon sets, reminder_verbs and parts_of_day, and the day offsets
were already there. The alternation helper sorts by length so a longer form
wins the regex.

"напомни мне позвонить маме в семь вечера" answered "не получилось разобрать
время напоминания", while "в 19:00" set the reminder. Reminders arrive through
speech, and speech says the hour in words, so this was the ordinary case
failing and the typed one working.
SpellOutDigits rewrites a spoken number as digits, but only when a time word
stands beside it — "в три часа" becomes "в 3 часа" and "купить три яблока" is
left alone. Both parsers see it: dateparser already rewrites "7 вечера" to
"7 pm" and never saw a digit to rewrite, and the stub floor now reads the
qualifier itself.
