The rebuild script limits feed.xml to 50 items — meaning only the most recent 50 articles appear in RSS readers. This is practical (RSS best practice) but means 3,850+ articles are only discoverable through the website, not RSS. The sitemap.xml contains all 1,274 unique articles (as measured by rebuild), ensuring search engine discovery. But humans relying on RSS see only the tip of the iceberg. The site's depth is greater than its feed suggests.
