The full external-link manifest
Every external URL on the site lives in a public manifest, regenerated on every build. A Cloudflare Worker validates a rolling subset on a daily cron and writes results to a Cloudflare D1 database. Broken links surface in the editorial dashboard with a Wayback snapshot fallback.

If a source on this page goes dark, it lands in the broken-links queue. If you find a link that points somewhere wrong, write to us at the address on the disclosure page.
