 5. **SEO object**: key sets (additive `lang`, `alternates`, `og.locale_alternates`, `fallbacks.site_text_skipped`); canonical table (pattern, override wins, no pattern keeps legacy, unassigned keeps legacy, `{lang}` keeps `pt-BR`); `fallbacks.canonical` values; og:locale Examples table including `en` with Site.Locale `en` and `null` (empty string, alternates `[]`); `og.locale_alternates`; the description/title fallback tables and `site_text_skipped`; the default-change limitation scenario. Existing `test/seo_output_*` specs are amended only where they assert the exact key set, the `og.locale` of an assigned article, or the canonical of a site that has a pattern (unassigned and pattern-less cases must pass unchanged).
 6. **Sitemap**: eligible versions only, `lang` key, localized urls with a pattern and legacy urls without, `X-Total-Count`, paging invariants unchanged.
 7. **Languages read**: `social_locale_state` `derived` with `en_GB` for bare `en` and Site.Locale `en-GB`, `not_set` for bare Site.Locale; amend `test/site_languages_*` accordingly.
+7b. **Rate limit**: TestPublicReadRateLimit sends 120 requests alternating the exact lookup and the sitemap from one address, then asserts 429 with Retry-After on the exact lookup, the sitemap and the story resolution, and 200 for another address.
+7c. **Language-aware SEO check and status**: TestCheckArticleSEOIsLanguageAware (fakes) and TestArticleSEOIndex* "The site description counts for the default language only and follows a default change" (SQLite and real databases).
 8. **MCP**: `list_articles` forwards `lang` (assert the request URL with a stub HTTP client in `internal/infrastructure/mcpserver`'s existing test style), tool descriptions contain no "cannot be changed".
 9. **Catalogue drift**: `test/api_catalogue_drift_test.go` green with the two new routes; `web/src/data/apiCatalogue.ts` counts updated.
 10. **Layering**: existing layering tests stay green; the public handler imports no persistence, models or gorm.
