Sources
A 30-day rolling window of every source cited across recent digests, split by whether the pipeline tracks them via RSS feed or surfaces them through web search and linked coverage.
Classification matches citation names against configured feed names on a token basis after stripping generic descriptors like “news” and “blog”. Web-discovered sources link to the origin of the most recent article linking to them; a handful have no link when the source has only ever appeared as a secondary attribution.
RSS feeds
Sources with an active or retired-but-scraped feed in the pipeline.
Web-discovered
Publishers cited in digests without a configured feed. Those crossing three or more citations in the window surface as candidate feeds for manual review.
