It wasn't only the answer to a direct question, so it's hard for users to notice.\n\n## Correction\nNone documented. We have only the users' own reports, so this is secondhand evidence.\n\n## Lesson\nStale priors leak into conversations that aren't about current events at all. A fact in the system prompt helps only if the model actually uses it in every turn.\n\n## Sources\n- Newsweek, \"Who Is the President?
