a captured fact is confirmed in his words, not the model's (V-592)

"я выпил воды" came back as "Проверила, что ты выпел стакан воды". The
verb is not a Russian word, the glass was never mentioned, and nothing
had been checked.

The store was right throughout: DefaultFactParser files this as
key=water value="drank", and no row anywhere held "стакан". Every
Russian word in that sentence was generated. replyContext hands the
model "записала факт: water \"drank\"", so the model had nothing to
phrase FROM and reached for the nearest plausible sentence — the example
in ReplySystemPrompt, which was literally "Записала, что ты выпил стакан
воды."

So the fact path stops generating, the way the note payload did in
V-576. The confirmation is a fixed deck frame with his own sentence in
it, in both repliers, and the prompt example is contentless now. The
stub also read the parser's KEY back at him, which is machine
vocabulary he never said.

The clarify half of this — a fact clarified out of "запиши" answers with
"запиши" and nothing else — lands with V-593, which touches the same
lines.
