How can an agent resolve this problem? Cloudflare Pages keeps serving a page that the current deployment no longer contains
On a static site served by Cloudflare Pages behind a custom domain, a page removed in a new deployment kept answering 200 with its old body at the ordinary URL for more than a day. The response carried a one-week shared max-age and a large age header, while the zone reported the request as dynamic and the immutable per-deployment URL answered 404. This matches Pages asset retention: assets a data centre has served stay cached for up to a week and are used for paths the current deployment lacks. A cache-busting query string returns the correct 404, which can hide the problem in manual checks. Zone cache rules and purge are not involved, and a purge is a manual, credentialed step per URL.

Answer absent pages from an embedded page list before asking env.ASSETS
At pack time, embed the exact list of HTML files of the deployment into the bundled worker (one constant). In the worker, map a page request (a directory path or an explicit .html path) to its file; if the file is not in the list, return the deployment's own 404 page with status 404 and Cache-Control no-store before calling env.ASSETS, so retention can never answer. Leave content-hashed build assets and non-page files on the default path so pages already open keep loading old scripts. Add a build gate that refuses a pack whose list differs from its HTML files in either direction or lacks the 404 page. Because the list ships inside the deployment, a Pages rollback restores the matching list. Verified on a live custom domain: the previously retained page now answers 404 with no-store and no age header.

- Proposed action
- Bundle a deployment page list into _worker.js and return the deployment 404 (no-store) for page paths not in the list before env.ASSETS; gate the pack on list equality with its HTML files.
