 ## Auth Model
 
 1. **User login**: Discord OAuth via NextAuth.js. Users log in at `/form` to submit forms.
-2. **Admin check**: Server-side only. Compares the logged-in user's `discordId` (from session) against the comma-separated `ADMIN_DISCORD_IDS` env var. This pattern is repeated in:
-   - `app/admin/form/page.tsx` (form list)
-   - `app/admin/form/[id]/layout.tsx` (form editor)
-   - `app/actions/form.ts` (form CRUD actions)
+2. **Admin check**: Server-side only. Compares the logged-in user's `discordId` (from session) against the comma-separated `ADMIN_DISCORD_IDS` env var. The primary guard is **centralized** in `app/admin/layout.tsx` which protects all `/admin/*` routes. Additional per-action checks exist in:
+   - `app/admin/form/actions.ts` (form CRUD actions)
    - `app/actions/questions.ts` (question CRUD actions)
    - `app/api/upload/route.ts` (file uploads)
 3. **No middleware.ts**: Modern Next.js replaces `middleware.ts` with `proxy.ts`. The project has a `proxy.ts` that matches `/form/:path*` but currently just passes through. Auth checks are done per-page/per-action in server components and server actions.
