Read-only over rows that exist. No new mechanism and no new storage: every
fact he tapped in already carries a source and a timestamp, and the history
source only reads them back.

Only "tap:" sources, and only the last day. A fact written by a poller, an
inference or the ambient relay is a thing she learned rather than a thing he
said, and reading those back under "что я тебе говорил?" would put words in
his mouth. Five at a time, which is what fits in one spoken breath — the rest
are on /history, which is the surface for reading a list.

Above the recall sources, with the others that read his own rows: the notes
pass would otherwise answer this from whatever note is nearest, which reads
as an answer and is not one. The matcher wants both halves of a history
phrase and steps aside when he names a topic, so "что я говорил про сервер"
stays a recall question.
