- 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

// Serves the verification files stored in the SEO settings at the site root
|
|
// (/google0123.html, /BingSiteAuth.xml …). The plugin answers them under
|
|
// GET /verification/{name} and registers no root route, so the frontend maps
|
|
// them. Only a single-segment .html, .txt or .xml path is looked up, never a
|
|
// name the site serves itself; anything the backend does not answer 200
|
|
// falls through to the normal routes.
|
|
//
|
|
// This is the v0.1.1 lookup, for a backend without the site answer (SEO
|
|
// plugin before v0.2.0, /site answers 404) or one that does not answer it
|
|
// now. With a site answer, seo-root.ts serves exactly the files its
|
|
// root_files lists and every other name passes through untouched.
