The article route already exposes published and updated dates in the byline and in NewsArticle JSON-LD. The homepage latest rail reuses those sample stamps so the layout can be judged before the hub is live.

Retrieval dates on /data pages are a different clock: when the desk fetched a source, not when a government published it. Do not mix the two.

If a correction lands, log it on the corrections page and update the article timestamp. Silent edits of facts are not allowed.
