 ## Architecture
 
-- **Entry**: `src/main.jsx` → `src/App.jsx`
+- **Entry**: `src/main.jsx` → wrapped in `<ThemeProvider>` (next-themes) → `src/App.jsx`
 - **Auth**: `src/context/AuthContext.jsx` — Supabase Auth + `members` table profile (role: admin/member)
-- **Routing**: `src/App.jsx` — public routes `/login`, `/register`, `/accept-invite`; protected routes wrapped in `<ProtectedRoute>`; admin-only routes (`/members`, `/skills`) also wrapped in `<AdminRoute>`
+- **Routing**: `src/App.jsx` — public routes `/login`, `/register`, `/accept-invite`; protected routes wrapped in `<ProtectedRoute>`; admin-only routes (`/members`, `/skills`) also wrapped in `<AdminRoute>` + `<Suspense>` (React.lazy code splitting)
+- **Error handling**: `<ErrorBoundary>` wraps all protected routes
 - **Pages**: `src/pages/` — Dashboard, Members, Skills, SkillMatrix, History, Profile
 - **UI**: `src/components/ui/` — shadcn components (radix-nova style, JS, no TSX)
 - **Supabase client**: `src/lib/supabase.js` — reads `VITE_SUPABASE_URL` / `VITE_SUPABASE_ANON_KEY` from env
 - **Path alias**: `@/*` → `src/*` (configured in both `vite.config.js` and `jsconfig.json`)
 
+## Data Layer
+
+### Custom hooks in `src/hooks/`
+
+| Hook | Returns | Notes |
+|---|---|---|
+| `useMembers()` | `{ members, loading, refetch }` | Full-text search via GIN index |
+| `useSkills()` | `{ skills, loading, refetch }` | Includes `category:category_id(name)` join |
+| `useCategories()` | `{ categories, loading, refetch }` | Ordered by name |
+| `useSkillLevels()` | `{ levels, loading, refetch, updateLevel, getAverageSkillRating }` | `levels` is a `{memberId-skillId → level}` map. Has real-time subscription |
+| `useHistory()` | `{ history, loading, count, page, totalPages, filters, setFilter, nextPage, prevPage, refetch }` | Paginated (50/page), real-time on INSERT |
+
+### Data fetching patterns
+- Hooks call Supabase directly (no additional API layer)
+- No global state management (hooks + local state only)
+- Real-time subscriptions via `supabase.channel()` on `skill_levels` and `skill_history`
+
 ## Supabase
 
 - DB schema + RLS policies in `supabase/migrations/001_init.sql`
 - Tables: `categories`, `skills`, `members`, `level_descriptions`, `skill_levels`, `skill_history`, `invitations`
 - `handle_new_user()` trigger auto-creates a `members` row on auth signup
 - RLS: read-all for most tables, write restricted to admin role
-- `.env` points to a local Supabase instance (`192.168.2.220:8000`) — this is committed but `.env` is gitignored; adjust for your environment
+- UPDATE policies include `WITH CHECK` matching the `USING` clause
+- `invitations_read_admin` policy filters `expires_at > now()`
+- Full-text search enabled via GIN indexes on `skills.name` and `members.full_name`
+- Realtime publication enabled on `skill_levels` and `skill_history`
