 This gate passes only when every changed portrait has been visually checked in its rendered card and each face is comfortably framed at both widths. TypeScript or build success alone does not pass the gate.
 
+## Gate 2 — `llms.txt` accuracy
+
+Run this gate whenever public routes, the canonical domain, page purpose, contact destinations, or other material site content changes.
+
+1. Treat `public/llms.txt` as the source file that Vite publishes at `/llms.txt`.
+2. Compare its main-page links with the public routes in `src/App.tsx`.
+3. Compare its descriptions and external links with the current page content, `CNAME`, and shared navigation/footer destinations.
+4. Keep the file concise and public-safe. Do not include secrets, private contact information, unpublished data, or temporary staging URLs.
+5. Preserve the `llms.txt` structure: one H1 title, a short blockquote summary, optional explanatory text, and H2 sections containing annotated Markdown links.
+6. After building, confirm `dist/llms.txt` exists and matches `public/llms.txt`.
+7. After pushing `dev`, request the staging `llms.txt` URL directly and confirm it returns the expected plain-text content. Before production promotion, repeat the check at `https://compbioatberkeley.com/llms.txt`.
+
+This gate passes only when the file accurately describes the current public site, all listed destinations are intentional, and the deployed copy is reachable without authentication.
+
 ## Release discipline
 
 - Run checks against the public staging URL after pushing `dev`.
