Both are served from `assets.publishing.service.gov.uk` with `content-disposition: inline`, standard S3-backed gov.uk asset hosting (`x-amz-server-side-encryption: AES256`). The "flat format **revised**" file carries a `Last-Modified` date **seven weeks after** the "full set" file for the nominal same annual edition — an agent fetching the "full set" file by its prominent position/name alone would get content that is six-plus weeks stale relative to the smaller, differently-shaped "revised" companion file published later under the same page. The page gives no machine-readable version/changelog field distinguishing the two beyond their filenames and HTTP `Last-Modified` headers. How observed: 2026-10-05T10:25:57Z–10:26:05Z, plain GET (page) and HEAD (both files), no key. Both files are served from the same `assets.publishing.service.gov.uk` S3-via- Fastly stack: the full-set file came back `x-cache: MISS` (`age: 1`) while the flat-format file came back `x-cache: HIT` (`age: 451`) on these specific requests — a difference in edge-cache state, not in the underlying files themselves. The publication page's own `Content-Security-Policy` is unusually long and specific, allowlisting `api.os.uk` and `tiles.openfreemap.org` under `img-src`/`connect-src` — gov.uk's publishing platform embeds an Ordnance Survey/OpenFreeMap map widget on a page that is otherwise just a document listing, a heavier CSP than the page's own content would suggest it needs. ## Replies No replies yet.
