+
+## Backend Endpoints
+
+All necessary backend endpoints were already in place. The backend provides:
+- Auth: register, login, refresh, logout, forgot-password, reset-password
+- Public: products, blog, gallery, farmers, prices, inquiries, chat preview
+- Portal: dashboard, profile, orders, chat, resources, farm-profile, crop-logs, bookings, market-prices
+- Admin: dashboard, analytics, users, orders, inquiries, blog, products, gallery, resources, farmers, prices, bookings, ai-config, chat-logs
+
+### Backend additions/fixes from prior session
+- `POST /api/auth/register` creates and returns `refresh_token`
+- `GET /api/blog` and `GET /api/blog/:slug` return `author_name` via `BlogPostWithAuthor` model
+
+---
+
+## Auth Flow
+
+- `access_token` and `refresh_token` are stored in `localStorage` after login/register
+- User object stored in `localStorage` as JSON
+- `api.ts` interceptor auto-attaches `Bearer <access_token>` to every request
+- On 401, interceptor auto-refreshes using `refresh_token`; if that fails, redirects to `/login`
+- `/portal/*` routes require `isAuthenticated()` (access token present)
+- `/admin/*` routes require `isAuthenticated()` AND `user.role === "admin"`
+- Backend admin endpoints enforce admin role via `AdminUser` extractor middleware
+
+---
+
+## Key Files Changed
+
+### Frontend
+- `src/hooks/useCart.ts` — implemented Zustand cart store (was broken placeholder)
+- `src/router/index.tsx` — added `/admin/users/:id` route
+- `src/pages/admin/AdminOrders.tsx` — replaced stub
+- `src/pages/admin/AdminInquiries.tsx` — replaced stub
+- `src/pages/admin/AdminBlog.tsx` — replaced stub
+- `src/pages/admin/AdminBlogEditor.tsx` — replaced stub
+- `src/pages/admin/AdminProducts.tsx` — replaced stub
+- `src/pages/admin/AdminGallery.tsx` — replaced stub
+- `src/pages/admin/AdminResources.tsx` — replaced stub
+- `src/pages/admin/AdminFarmers.tsx` — replaced stub
+- `src/pages/admin/AdminPrices.tsx` — replaced stub
+- `src/pages/admin/AdminAiConfig.tsx` — replaced stub
+- `src/pages/admin/AdminAnalytics.tsx` — replaced stub
+
+---
+
+## Data Shape Notes
+
+All API calls use consistent response parsing:
+```ts
+const data = res.data?.data ?? res.data
+```
+This handles both `{ success: true, data: ... }` wrapper and bare responses.
+
+---
+
+## Loading / Error / Empty States
+
+Every connected page includes:
+- **Loading state**: spinner via `Loader2` from lucide-react
+- **Error state**: red banner with message
+- **Empty state**: dashed border card with message
+
+---
+
+## Remaining Limitations
+
+1. **No file upload for gallery/resources** — accepts URL strings only; a full file upload integration would require R2/S3 presigned URL support (backend `services/r2.rs` is scaffolded but not wired to routes)
+2. **Blog editor uses plain textarea** — a rich text editor (TipTap) is installed but not wired; content is stored as plain text
+3. **No pagination UI** — most list endpoints support pagination params but the frontend does not currently expose pagination controls
+4. **Password reset** — backend route exists (`/api/auth/reset-password`) but the frontend ForgotPasswordPage sends email only; no reset form is implemented
+5. **CORS** — backend uses `allow_origin(Any)` which is suitable for development; should be restricted to the frontend origin in production
+
+---
+
+## How to Run Locally
+
+### Backend
+```bash
+cd willbry-backend
+cp .env.example .env
+# Edit .env with your DATABASE_URL, JWT_SECRET, GROQ_API_KEY, etc.
+cargo run
+# Backend runs on http://localhost:8080
+```
+
+### Frontend
+```bash
+cd willbry-frontend
+cp .env.example .env  # or create .env with VITE_API_URL=http://localhost:8080/api
+npm install
+npm run dev
+# Frontend runs on http://localhost:5173
+```
+
+---
+
+## How to Create or Test Admin Access
+
+1. Register a new user via `/register`
+2. In your PostgreSQL database, update the user's role:
+   ```sql
+   UPDATE users SET role = 'admin' WHERE email = 'your@email.com';
+   ```
+3. Log in — you will be redirected to `/admin` after login
+
+Alternatively, seed an admin user directly:
+```sql
+INSERT INTO users (id, full_name, email, password_hash, role, user_type, verified, active)
+VALUES (
+  gen_random_uuid(),
+  'Admin User',
+  'admin@willbry.com',
+  '$argon2id$...', -- use argon2 hash of your password
+  'admin',
+  'client',
+  true,
+  true
+);
+```
+
+---
+
