The evidence branch of PhraseQuery framed every source as "твои заметки" and
joined them into one quoted run-on. A live search snippet is not his note, and
a run-on gives a 1.7B one blurred claim to merge rather than sources to answer
from. That is the shape that named Левитан as the author of Война и мир.
Sources now arrive numbered, one per line, and the system prompt says three
ways that the answer comes out of them: only from the sources, say plainly
when they do not answer, add nothing of your own.
Blank sources take the knowledge branch. One empty string used to reach the
evidence branch and ask the model to answer from an empty list, which is the
one prompt guaranteed to make it fill the gap from memory.
