- server/middleware/seo-root.ts proxies /robots.txt, /sitemap.xml,
/sitemap-<name>.xml, /llms.txt and the verification and IndexNow key
files the site answer lists in root_files, with the backend's status,
content type and X-Robots-Tag; a backend failure is 503 Retry-After 60
- server/lib/site.ts caches GET /_seo/api/v1/site (300 s, cleared by the
purge); a backend without it (404) keeps the v0.1.1 behaviour: no root
proxies, the verification lookup by name
- the 404 report and the verification lookup honour seo.cms and rootFiles
- smoke runs for the layer off (seo.cms and the v0.1.1 enabled switch), the
CMS down (fail open) and no 404 token; npm run purge:check
