infra(domain): switch production domain to docs.internetcomputer.org

 **Rationale:** Dynamic SVG generation in the build plugin adds ~30 lines of complexity for a one-time change. Static is simpler and good enough.
 **Alternatives considered:** Generate SVG dynamically in `plugins/astro-agent-docs.mjs` using `siteUrl` from Astro config (more robust, but over-engineered for a single domain change)

+## 2026-04-28: Production domain cutover to docs.internetcomputer.org
+
+**Context:** The site was previously served from `beta-docs.internetcomputer.org` as a staging domain during the transition from `dfinity/portal`. The portal has now been retired and this site is the canonical ICP developer docs.
+**Decision:** Switch all domain references from `beta-docs.internetcomputer.org` to `docs.internetcomputer.org`. Updated files: `astro.config.mjs` (site URL + og/twitter/schema.org meta), `public/robots.txt` (sitemap), `public/og-image.svg` (footer text), `README.md`, `AGENTS.md` (never-link rule + portal tracking section), `scripts/validate.js` (error messages). The `docs.internetcomputer.org` lint rule in validate.js is kept — it still enforces relative paths for internal links.
+**Rationale:** The beta domain was always a temporary staging address. With the portal retired, `docs.internetcomputer.org` is the permanent home.
+**Alternatives considered:** Keep beta domain as a redirect origin (handled at DNS/CDN level, not in code)

-The old portal (`dfinity/portal`) is still live during the transition period.
-- **Ignore:** dfx-only changes, JSX/component changes, release notes, NNS dapp guides
-- **Flag for rewrite:** Content updates to topics we cover
-- **Evaluate:** New content — does it belong in the new docs?
+The old portal (`dfinity/portal`) has been replaced by this site. The `.sources/portal` submodule is kept as a read-only reference for spec content (see `ic.did` sync checklist above) but no longer needs active monitoring for content changes.

 # ICP Developer Docs
 
-Developer documentation for the [Internet Computer](https://internetcomputer.org) — built with [Astro](https://astro.build) + [Starlight](https://starlight.astro.build), deployed at [beta-docs.internetcomputer.org](https://beta-docs.internetcomputer.org).
+Developer documentation for the [Internet Computer](https://internetcomputer.org) — built with [Astro](https://astro.build) + [Starlight](https://starlight.astro.build), deployed at [docs.internetcomputer.org](https://docs.internetcomputer.org).
 
 ## Background
 
-The existing ICP docs live at [internetcomputer.org/docs](https://internetcomputer.org/docs), sourced from [dfinity/portal](https://github.com/dfinity/portal) (Docusaurus). That site accumulated content over years without a consistent information architecture, making it hard to navigate and harder to keep accurate.
-
-This repo is a ground-up rewrite: a flat Diataxis structure (Getting Started, Guides, Concepts, Languages, Reference), content verified against pinned upstream repos, and a workflow built for both human contributors and AI coding agents from day one.

It replaces the previous [dfinity/portal](https://github.com/dfinity/portal) (Docusaurus) site.
 
 ## Current state
 
-Most pages are content-complete. A small number of pages remain as stubs (vetkeys, encryption). The existing production docs remain live during the transition.
