+"""The agent's own answers must not come back to it as evidence.
+
+Every answer is written to memory as an episode so a conversation has
+continuity. Recall then returned those episodes as ambient evidence, which
+closes a loop with no damping: an answer is a near-perfect lexical match for
+the question that produced it, so it becomes the top hit the next time that
+question is asked, and the agent cites itself.
+
+Observed before this fix: asked three times about a conference invitation held
+in a sandbox file, recall returned the agent's own three previous "there is no
+information about it" replies as the top three hits. Every retry added another
+denial, so rephrasing made it worse rather than better, and the agent grew more
+confident about something it had never checked.
+
+What must keep working is as important as what must stop. The user's own
+messages are evidence, and so are facts written by `remember_explicit_fact` --
+cross-channel recall depends on them.
