What this governance record addresses
A source register should not be a timeless list of links. This page publishes each source's role, geography, lifecycle, review interval, due date and automated result; row dates distinguish the 25 July 2026 baseline from targeted rechecks on 30 July and 2026-08-27.
Important boundary: Even HTTP 200 can redirect away from the intended record; HTTP 202, 403 or 429 does not automatically make a source broken. Automated retrieval does not validate content, edition, amendment or withdrawal status, or local adoption.
