Commit

Hot topics comes from headlines, not Trending scores. Approved top-level commits about a specific development get brief shared headlines; the Decisions API checks suitability and shortlists similar existing headlines, then DeepSeek through OpenCode writes a new one if nothing matches. Headlines expire after fourteen days without a new commit link. Up to five show in the desktop sidebar above Who to follow. Trending is separate: replies weigh most, then quotes, then stars, with diminishing returns.
