Sweep every topic in the active watchlist for genuinely new items, judge their relevance and significance, and write a cited digest plus a structured changelog.

Design principle

Scripts enforce mechanics; the agent makes editorial judgments. You choose search queries, assess source credibility, and judge relevance/significance. The scripts only decide mechanical questions: is this URL already seen, is the topic known, or is the host explicitly excluded? Never re-implement dedup or exclude filtering with your own judgment: always pipe candidates through diff_state.py, and always advance state through commit_state.py.
