+### Phase 32: SEO foundation
+
+**Goal:** As a site editor on any SummerCMS application, I want search-engine optimisation built into the CMS, going further than WinterCMS, so that every site ships correct, editable SEO without per-site work. This covers:
+- an SEO tab on every content record and a global SEO settings screen;
+- title, meta description, canonical and meta robots fields, Open Graph and Twitter Card tags;
+- structured data per page type (article, home page, service pages; no e-commerce yet);
+- a pagination mechanism;
+- the XML sitemap extended, plus a default HTML sitemap linked from the home page;
+- 301/302 redirects and robots.txt, both editable in the admin;
+- a correct heading hierarchy (one H1, then nested H2/H3);
+- basic hreflang;
+- a noindex policy for filter pages, login and signed-in user pages;
+- a server-side rendering guarantee for the headless frontends, so that Googlebot sees all content and links.
+**Mode:** mvp
+**Depends on:** Phase 16 (vue-journal-layer), Phase 17 (sitemap plugin)
+**Repos:** `summercms.go` (framework SEO seam and admin), `sm-journal-plugin`, `sm-sitemap-plugin`, a new shared plugin where the discussion decides (redirects, robots.txt, global SEO), `vue-journal-layer` and the other Nuxt layers; scope fixed in discuss-phase
+**Requirements**: TBD
+**Success Criteria** (what must be TRUE):
+
+  1. To be fixed in `/msd-discuss-phase 32`.
+  2. The new code has unit tests, delivered in the phase's last plan.
