Merge the invented note and the repeated ask (#238)

V-592 is a phrasing defect. The store was never wrong: DefaultFactParser files
я выпил воды as key=water value=drank, and no стакан reaches the index. The
glass was copied out of the prompt. ReplySystemPrompt's example was literally
'Записала, что ты выпил стакан воды', replyContext hands the model
'записала факт: water "drank"' with no Russian to work from, and the nearest
plausible sentence in context was the example itself. выпел is the 1.7B
garbling the verb.

So the fact path stops generating and echoes, per V-576. The prompt example is
contentless now. Two smaller things fell out: the stub read the parser's key
back at him as 'отметила: water = "drank"', and a fact clarified out of запиши
confirmed as запиши, because a fact answer fills no Text slot.

V-593: whenKnownOf reads the three things he must say off the same predicates
whenGapOf uses. An answer that moved any of them forward puts 'Поняла: <his
words>.' between the clock and the question. An answer that moved nothing
repeats the question unchanged, which is honest. The acknowledgement echoes and
never restates, for the same reason as V-592.

A new differs field on a trace turn fails a byte-identical consecutive reply.

Open for the owner: whether the clock repeats on every ask of one flow. He
ruled that she states the time, not that she states it on every question.
