- Nitro middleware resolves page requests once and hands the answer to the render (event.context.seo); the route middleware reuses it - useCmsSeo: html lang, hreflang links, og:locale and exactly one JSON-LD script with one @graph (CMS nodes plus useSchemaNode nodes, merged by @id) - local module (configKey seo): cms (alias of public.seo.enabled), breadcrumbs, links.newTabHint, rootFiles, resolveFiles - GET /api/__seo__/resolve for client navigation through the Nuxt server - smoke harness: count=, exact header=, noheader=, reqheader=, repeated options, resolves/apicalls/noreport lines, --no-site; v0.1.1 suite runs unchanged against a backend without /site
