+### 🔴 CRITICAL: Auth Store Dependency Injection Pattern
+
+**ALWAYS use `useAuth()` from `AuthContext`, NEVER import `useAuthStore` directly!**
+
+```typescript
+// ❌ WRONG - Bypasses dependency injection
+import { useAuthStore } from '@/lib/stores/authStore';
+const { user, isAuthenticated } = useAuthStore();
+
+// ✅ CORRECT - Uses dependency injection
+import { useAuth } from '@/lib/auth/AuthContext';
+const { user, isAuthenticated } = useAuth();
+```
+
+**Why This Matters:**
+- E2E tests inject mock stores via `window.__TEST_AUTH_STORE__`
+- Unit tests inject via `<AuthProvider store={mockStore}>`
+- Direct `useAuthStore` imports bypass this injection → **tests fail**
+- ESLint will catch violations (added Nov 2025)
+
+**Exceptions:**
+1. `AuthContext.tsx` - DI boundary, legitimately needs real store
+2. `client.ts` - Non-React context, uses dynamic import + `__TEST_AUTH_STORE__` check
+
+**See**: `frontend/docs/ARCHITECTURE_FIX_REPORT.md` for full details.

+
+## Phase 8: Organization Management (Admin)
+
+**Status:** 📋 TODO (Next Phase)
+**Estimated Duration:** 3-4 days
+**Prerequisites:** Phase 7 complete ✅
+
+**Summary:**
+Implement complete admin organization management system following the same patterns as user management. Organizations are multi-tenant containers with member management and role-based access.
+
+### Planned Implementation
+
+**Backend API Endpoints Available:**
+- `GET /api/v1/admin/organizations` - List organizations with pagination
+- `POST /api/v1/admin/organizations` - Create organization
+- `GET /api/v1/admin/organizations/{id}` - Get organization details
+- `PATCH /api/v1/admin/organizations/{id}` - Update organization
+- `DELETE /api/v1/admin/organizations/{id}` - Delete organization
+- `GET /api/v1/admin/organizations/{id}/members` - List org members
+- `POST /api/v1/admin/organizations/{id}/members` - Add member
+- `DELETE /api/v1/admin/organizations/{id}/members/{user_id}` - Remove member
+- `PATCH /api/v1/admin/organizations/{id}/members/{user_id}` - Update member role
+
+### Task 8.1: Organization Hooks & Components
+
+**Hooks to Create** (`src/lib/api/hooks/useAdmin.tsx`):
+- `useAdminOrganizations` - List organizations with pagination/filtering
+- `useCreateOrganization` - Create new organization
+- `useUpdateOrganization` - Update organization details
+- `useDeleteOrganization` - Delete organization
+- `useOrganizationMembers` - List organization members
+- `useAddOrganizationMember` - Add member to organization
+- `useRemoveOrganizationMember` - Remove member
+- `useUpdateMemberRole` - Change member role (owner/admin/member)
+
+**Components to Create** (`src/components/admin/organizations/`):
+- `OrganizationManagementContent.tsx` - Main container
+- `OrganizationListTable.tsx` - Data table with org list
+- `OrganizationFormDialog.tsx` - Create/edit organization
+- `OrganizationActionMenu.tsx` - Per-org actions
+- `OrganizationMembersDialog.tsx` - Member management dialog
+- `MemberListTable.tsx` - Member list within org
+- `AddMemberDialog.tsx` - Add member to organization
+- `BulkOrgActionToolbar.tsx` - Bulk organization operations
+
+### Task 8.2: Organization Features
+
+**Core Features:**
+- Organization list with pagination
+- Search by organization name
+- Filter by member count
+- Create new organizations
+- Edit organization details
+- Delete organizations (with member check)
+- View organization members
+- Add members to organization
+- Remove members from organization
+- Change member roles (owner/admin/member)
+- Bulk operations (delete multiple orgs)
+
+**Business Rules:**
+- Organizations with members cannot be deleted (safety)
+- Organization must have at least one owner
+- Owners can manage all members
+- Admins can add/remove members but not other admins/owners
+- Members have read-only access
+
+### Task 8.3: Testing Strategy
+
+**Unit Tests:**
+- All hooks (organization CRUD, member management)
+- All components (table, dialogs, menus)
+- Form validation
+- Permission logic
+
+**E2E Tests** (`e2e/admin-organizations.spec.ts`):
+- Organization list and pagination
+- Search and filtering
+- Create organization
+- Edit organization
+- Delete organization (empty and with members)
+- View organization members
+- Add member to organization
+- Remove member from organization
+- Change member role
+- Bulk operations
+- Accessibility

 ## 6. Authentication Architecture
 
-### 6.1 Token Management Strategy
+### 6.1 Context-Based Dependency Injection Pattern
+
+**Architecture Overview:**
+
+This project uses a **hybrid authentication pattern** combining Zustand for state management and React Context for dependency injection. This provides the best of both worlds:
+
+```
+Component → useAuth() hook → AuthContext → Zustand Store → Storage Layer → Crypto (AES-GCM)
+                                  ↓
+                          Injectable for tests
+                                  ↓
+                Production: Real store | Tests: Mock store
+```
+
+**Why This Pattern?**
+
+✅ **Benefits:**
+- **Testable**: E2E tests can inject mock stores without backend
+- **Performant**: Zustand handles state efficiently, Context is just a thin wrapper
+- **Type-safe**: Full TypeScript inference throughout
+- **Maintainable**: Clear separation (Context = DI, Zustand = state)
+- **Extensible**: Easy to add auth events, middleware, logging
+- **React-idiomatic**: Follows React best practices
+
+**Key Design Principles:**
+1. **Thin Context Layer**: Context only provides dependency injection, no business logic
+2. **Zustand for State**: All state management stays in Zustand (no duplicated state)
+3. **Backward Compatible**: Internal refactor only, no API changes
+4. **Type Safe**: Context interface exactly matches Zustand store interface
+5. **Performance**: Context value is stable (no unnecessary re-renders)
+
+### 6.2 Implementation Components
+
+#### AuthContext Provider (`src/lib/auth/AuthContext.tsx`)
+
+**Purpose**: Wraps Zustand store in React Context for dependency injection
+
+```typescript
+// Accepts optional store prop for testing
+<AuthProvider store={mockStore}>  // Unit tests
+  <App />
+</AuthProvider>
+
+// Or checks window global for E2E tests
+window.__TEST_AUTH_STORE__ = mockStoreHook;
+
+// Or uses production singleton (default)
+<AuthProvider>
+  <App />
+</AuthProvider>
+```
+
+**Implementation Details:**
+- Stores Zustand hook function (not state) in Context
+- Priority: explicit prop → E2E test store → production singleton
+- Type-safe window global extension for E2E injection
+- Calls hook internally (follows React Rules of Hooks)
+
+#### useAuth Hook (Polymorphic)
+
+**Supports two usage patterns:**
+
+```typescript
+// Pattern 1: Full state access (simple)
+const { user, isAuthenticated } = useAuth();
+
+// Pattern 2: Selector (optimized for performance)
+const user = useAuth(state => state.user);
+```
+
+**Why Polymorphic?**
+- Simple pattern for most use cases
+- Optimized pattern available when needed
+- Type-safe with function overloads
+- No performance overhead
+
+**Critical Implementation Detail:**
+```typescript
+export function useAuth(): AuthState;
+export function useAuth<T>(selector: (state: AuthState) => T): T;
+export function useAuth<T>(selector?: (state: AuthState) => T): AuthState | T {
+  const storeHook = useContext(AuthContext);
+  if (!storeHook) {
+    throw new Error("useAuth must be used within AuthProvider");
+  }
+  // CRITICAL: Call the hook internally (follows React Rules of Hooks)
+  return selector ? storeHook(selector) : storeHook();
+}
+```
+
+**Do NOT** return the hook function itself - this violates React Rules of Hooks!
+
+### 6.3 Usage Patterns
+
+#### For Components (Rendering Auth State)
+
+**Use `useAuth()` from Context:**
+
+```typescript
+import { useAuth } from '@/lib/stores';
+
+function MyComponent() {
+  // Full state access
+  const { user, isAuthenticated } = useAuth();
+
+  // Or with selector for optimization
+  const user = useAuth(state => state.user);
+
+  if (!isAuthenticated) {
+    return <LoginPrompt />;
+  }
+
+  return <div>Hello, {user?.first_name}!</div>;
+}
+```
+
+**Why?**
+- Component re-renders when auth state changes
+- Type-safe access to all state properties
+- Clean, idiomatic React code
+
+#### For Mutation Callbacks (Updating Auth State)
+
+**Use `useAuthStore.getState()` directly:**
+
+```typescript
+import { useAuthStore } from '@/lib/stores/authStore';
+
+export function useLogin() {
+  return useMutation({
+    mutationFn: async (data) => {
+      const response = await loginAPI(data);
+
+      // Access store directly in callback (outside render)
+      const setAuth = useAuthStore.getState().setAuth;
+      await setAuth(response.user, response.token);
+    },
+  });
+}
+```
+
+**Why?**
+- Event handlers run outside React render cycle
+- Don't need to re-render when state changes
+- Using `getState()` directly is cleaner
+- Avoids unnecessary hook rules complexity
+
+#### Admin-Only Features
+
+```typescript
+import { useAuth } from '@/lib/stores';
+
+function AdminPanel() {
+  const user = useAuth(state => state.user);
+  const isAdmin = user?.is_superuser ?? false;
+
+  if (!isAdmin) {
+    return <AccessDenied />;
+  }
+
+  return <AdminDashboard />;
+}
+```
+
+### 6.4 Testing Integration
+
+#### Unit Tests (Jest)
+
+```typescript
+import { useAuth } from '@/lib/stores';
+
+jest.mock('@/lib/stores', () => ({
+  useAuth: jest.fn(),
+}));
+
+test('renders user name', () => {
+  (useAuth as jest.Mock).mockReturnValue({
+    user: { first_name: 'John', last_name: 'Doe' },
+    isAuthenticated: true,
+  });
+
+  render(<MyComponent />);
+  expect(screen.getByText('John Doe')).toBeInTheDocument();
+});
+```
+
+#### E2E Tests (Playwright)
+
+```typescript
+import { test, expect } from '@playwright/test';
+
+test.describe('Protected Pages', () => {
+  test.beforeEach(async ({ page }) => {
+    // Inject mock store before navigation
+    await page.addInitScript(() => {
+      (window as any).__TEST_AUTH_STORE__ = () => ({
+        user: { id: '1', email: 'test@example.com', first_name: 'Test', last_name: 'User' },
+        accessToken: 'mock-token',
+        refreshToken: 'mock-refresh',
+        isAuthenticated: true,
+        isLoading: false,
+        tokenExpiresAt: Date.now() + 900000,
+      });
+    });
+  });
+
+  test('should display user profile', async ({ page }) => {
+    await page.goto('/settings/profile');
+
+    // No redirect to login - authenticated via mock
+    await expect(page).toHaveURL('/settings/profile');
+    await expect(page.locator('input[name="email"]')).toHaveValue('test@example.com');
+  });
+});
+```
+
+### 6.5 Provider Tree Structure
+
+**Correct Order** (Critical for Functionality):
+
+```typescript
+// src/app/layout.tsx
+<AuthProvider>           {/* 1. Provides auth DI layer */}
+  <AuthInitializer />    {/* 2. Loads auth from storage (needs AuthProvider) */}
+  <Providers>            {/* 3. Other providers (Theme, Query) */}
+    {children}
+  </Providers>
+</AuthProvider>
+```
+
+**Why This Order?**
+- AuthProvider must wrap AuthInitializer (AuthInitializer uses auth state)
+- AuthProvider should wrap all app providers (auth available everywhere)
+- Keep provider tree shallow for performance
+
+### 6.6 Token Management Strategy
 
 **Two-Token System:**
 - **Access Token**: Short-lived (15 min), stored in memory/sessionStorage

+## 1. React Hooks
+
+### Pitfall 1.1: Returning Hook Function Instead of Calling It
+
+**❌ WRONG:**
+```typescript
+// Custom hook that wraps Zustand
+export function useAuth() {
+  const storeHook = useContext(AuthContext);
+  return storeHook;  // Returns the hook function itself!
+}
+
+// Consumer component
+function MyComponent() {
+  const authHook = useAuth();  // Got the hook function
+  const { user } = authHook();  // Have to call it here ❌ Rules of Hooks violation!
+}
+```
+
+**Why It's Wrong:**
+- Violates React Rules of Hooks (hook called conditionally/in wrong place)
+- Confusing API for consumers
+- Can't use in conditionals or callbacks safely
+- Type inference breaks
+
+**✅ CORRECT:**
+```typescript
+// Custom hook that calls the wrapped hook internally
+export function useAuth() {
+  const storeHook = useContext(AuthContext);
+  if (!storeHook) {
+    throw new Error("useAuth must be used within AuthProvider");
+  }
+  return storeHook();  // Call the hook HERE, return the state
+}
+
+// Consumer component
+function MyComponent() {
+  const { user } = useAuth();  // Direct access to state ✅
+}
+```
+
+**✅ EVEN BETTER (Polymorphic):**
+```typescript
+// Support both patterns
+export function useAuth(): AuthState;
+export function useAuth<T>(selector: (state: AuthState) => T): T;
+export function useAuth<T>(selector?: (state: AuthState) => T): AuthState | T {
+  const storeHook = useContext(AuthContext);
+  if (!storeHook) {
+    throw new Error("useAuth must be used within AuthProvider");
+  }
+  return selector ? storeHook(selector) : storeHook();
+}
+
+// Usage - both work!
+const { user } = useAuth();  // Full state
+const user = useAuth(s => s.user);  // Optimized selector
+```
+
+**Key Takeaway:**
+- **Always call hooks internally in custom hooks**
+- Return state/values, not hook functions
+- Support selectors for performance optimization
+
+---
+
+### Pitfall 1.2: Calling Hooks Conditionally
+
+**❌ WRONG:**
+```typescript
+function MyComponent({ showUser }) {
+  if (showUser) {
+    const { user } = useAuth();  // ❌ Conditional hook call!
+    return <div>{user?.name}</div>;
+  }
+  return null;
+}
+```
+
+**✅ CORRECT:**
+```typescript
+function MyComponent({ showUser }) {
+  const { user } = useAuth();  // ✅ Always call at top level
+
+  if (!showUser) {
+    return null;
+  }
+
+  return <div>{user?.name}</div>;
+}
+```
+
+**Key Takeaway:**
+- **Always call hooks at the top level of your component**
+- Never call hooks inside conditionals, loops, or nested functions
+- Return early after hooks are called
+
+---
+
+## 2. Context API & State Management
+
+### Pitfall 2.1: Creating New Context Value on Every Render
+
+**❌ WRONG:**
+```typescript
+export function AuthProvider({ children }) {
+  const [user, setUser] = useState(null);
+
+  // New object created every render! ❌
+  const value = { user, setUser };
+
+  return <AuthContext.Provider value={value}>{children}</AuthContext.Provider>;
+}
+```
+
+**Why It's Wrong:**
+- Every render creates a new object
+- All consumers re-render even if values unchanged
+- Performance nightmare in large apps
+
+**✅ CORRECT:**
+```typescript
+export function AuthProvider({ children }) {
+  const [user, setUser] = useState(null);
+
+  // Memoize value - only changes when dependencies change
+  const value = useMemo(() => ({ user, setUser }), [user]);
+
+  return <AuthContext.Provider value={value}>{children}</AuthContext.Provider>;
+}
+```
+
+**✅ EVEN BETTER (Zustand + Context):**
+```typescript
+export function AuthProvider({ children, store }) {
+  // Zustand hook function is stable (doesn't change)
+  const authStore = store ?? useAuthStoreImpl;
+
+  // No useMemo needed - hook functions are stable references
+  return <AuthContext.Provider value={authStore}>{children}</AuthContext.Provider>;
+}
+```
+
+**Key Takeaway:**
+- **Use `useMemo` for Context values that are objects**
+- Or use stable references (Zustand hooks, refs)
+- Monitor re-renders with React DevTools
+
+---
+
+### Pitfall 2.2: Prop Drilling Instead of Context
+
+**❌ WRONG:**
+```typescript
+// Passing through 5 levels
+<Layout user={user}>
+  <Sidebar user={user}>
+    <Navigation user={user}>
+      <UserMenu user={user}>
+        <Avatar user={user} />
+      </UserMenu>
+    </Navigation>
+  </Sidebar>
+</Layout>
+```
+
+**✅ CORRECT:**
+```typescript
+// Provider at top
+<AuthProvider>
+  <Layout>
+    <Sidebar>
+      <Navigation>
+        <UserMenu>
+          <Avatar />  {/* Gets user from useAuth() */}
+        </UserMenu>
+      </Navigation>
+    </Sidebar>
+  </Layout>
+</AuthProvider>
+```
+
+**Key Takeaway:**
+- **Use Context for data needed by many components**
+- Avoid prop drilling beyond 2-3 levels
+- But don't overuse - local state is often better
+
+---
+
+## 3. Zustand Store Patterns
+
+### Pitfall 3.1: Mixing Render State Access and Mutation Logic
+
+**❌ WRONG (Mixing patterns):**
+```typescript
+function MyComponent() {
+  // Using hook for render state
+  const { user } = useAuthStore();
+
+  const handleLogin = async (data) => {
+    // Also using hook in callback ❌ Inconsistent!
+    const setAuth = useAuthStore((s) => s.setAuth);
+    await setAuth(data.user, data.token);
+  };
+}
+```
+
+**✅ CORRECT (Separate patterns):**
+```typescript
+function MyComponent() {
+  // Hook for render state (subscribes to changes)
+  const { user } = useAuthStore();
+
+  const handleLogin = async (data) => {
+    // getState() for mutations (no subscription)
+    const setAuth = useAuthStore.getState().setAuth;
+    await setAuth(data.user, data.token);
+  };
+}
+```
+
+**Why This Pattern?**
+- **Render state**: Use hook → component re-renders on changes
+- **Mutations**: Use `getState()` → no subscription, no re-renders
+- **Performance**: Event handlers don't need to subscribe
+- **Clarity**: Clear distinction between read and write
+
+**Key Takeaway:**
+- **Use hooks for state that affects rendering**
+- **Use `getState()` for mutations in callbacks**
+- Don't subscribe when you don't need to
+
+---
+
+### Pitfall 3.2: Not Using Selectors for Optimization
+
+**❌ SUBOPTIMAL:**
+```typescript
+function UserAvatar() {
+  // Re-renders on ANY auth state change! ❌
+  const { user, accessToken, isLoading, isAuthenticated } = useAuthStore();
+
+  return <Avatar src={user?.avatar} />;
+}
+```
+
+**✅ OPTIMIZED:**
+```typescript
+function UserAvatar() {
+  // Only re-renders when user changes ✅
+  const user = useAuthStore((state) => state.user);
+
+  return <Avatar src={user?.avatar} />;
+}
+```
+
+**Key Takeaway:**
+- **Use selectors for components that only need subset of state**
+- Reduces unnecessary re-renders
+- Especially important in frequently updating stores
+
+---
+
+## 4. TypeScript Type Safety
+
+### Pitfall 4.1: Using `any` Type
+
+**❌ WRONG:**
+```typescript
+function processUser(user: any) {  // ❌ Loses all type safety
+  return user.name.toUpperCase();  // No error if user.name is undefined
+}
+```
+
+**✅ CORRECT:**
+```typescript
+function processUser(user: User | null) {
+  if (!user?.name) {
+    return '';
+  }
+  return user.name.toUpperCase();
+}
+```
+
+**Key Takeaway:**
+- **Never use `any` - use `unknown` if type is truly unknown**
+- Define proper types for all function parameters
+- Use type guards for runtime checks
+
+---
+
+### Pitfall 4.2: Implicit Types Leading to Errors
+
+**❌ WRONG:**
+```typescript
+// No explicit return type - type inference can be wrong
+export function useAuth() {
+  const context = useContext(AuthContext);
+  return context;  // What type is this? ❌
+}
+```
+
+**✅ CORRECT:**
+```typescript
+// Explicit return type with overloads
+export function useAuth(): AuthState;
+export function useAuth<T>(selector: (state: AuthState) => T): T;
+export function useAuth<T>(selector?: (state: AuthState) => T): AuthState | T {
+  const context = useContext(AuthContext);
+  if (!context) {
+    throw new Error("useAuth must be used within AuthProvider");
+  }
+  return selector ? context(selector) : context();
+}
+```
+
+**Key Takeaway:**
+- **Always provide explicit return types for public APIs**
+- Use function overloads for polymorphic functions
+- Document types in JSDoc comments
+
+---
+
+### Pitfall 4.3: Not Using `import type` for Type-Only Imports
+
+**❌ SUBOPTIMAL:**
+```typescript
+import { ReactNode } from 'react';  // Might be bundled even if only used for types
+```
+
+**✅ CORRECT:**
+```typescript
+import type { ReactNode } from 'react';  // Guaranteed to be stripped from bundle
+```
+
+**Key Takeaway:**
+- **Use `import type` for type-only imports**
+- Smaller bundle size
+- Clearer intent
+
+---
+
+## 5. Component Patterns
+
+### Pitfall 5.1: Forgetting Optional Chaining for Nullable Values
+
+**❌ WRONG:**
+```typescript
+function UserProfile() {
+  const { user } = useAuth();
+  return <div>{user.name}</div>;  // ❌ Crashes if user is null
+}
+```
+
+**✅ CORRECT:**
+```typescript
+function UserProfile() {
+  const { user } = useAuth();
+
+  if (!user) {
+    return <div>Not logged in</div>;
+  }
+
+  return <div>{user.name}</div>;  // ✅ Safe
+}
+
+// OR with optional chaining
+function UserProfile() {
+  const { user } = useAuth();
+  return <div>{user?.name ?? 'Guest'}</div>;  // ✅ Safe
+}
+```
+
+**Key Takeaway:**
+- **Always handle null/undefined cases**
+- Use optional chaining (`?.`) and nullish coalescing (`??`)
+- Provide fallback UI for missing data
+
+---
+
+### Pitfall 5.2: Mixing Concerns in Components
+
+**❌ WRONG:**
+```typescript
+function UserDashboard() {
+  const [users, setUsers] = useState([]);
+  const [loading, setLoading] = useState(false);
+
+  // Data fetching mixed with component logic ❌
+  useEffect(() => {
+    setLoading(true);
+    fetch('/api/users')
+      .then(res => res.json())
+      .then(data => setUsers(data))
+      .finally(() => setLoading(false));
+  }, []);
+
+  // Business logic mixed with rendering ❌
+  const activeUsers = users.filter(u => u.isActive);
+  const sortedUsers = activeUsers.sort((a, b) => a.name.localeCompare(b.name));
+
+  return <div>{/* Render sortedUsers */}</div>;
+}
+```
+
+**✅ CORRECT:**
+```typescript
+// Custom hook for data fetching
+function useUsers() {
+  return useQuery({
+    queryKey: ['users'],
+    queryFn: () => UserService.getUsers(),
+  });
+}
+
+// Custom hook for business logic
+function useActiveUsersSorted(users: User[] | undefined) {
+  return useMemo(() => {
+    if (!users) return [];
+    return users
+      .filter(u => u.isActive)
+      .sort((a, b) => a.name.localeCompare(b.name));
+  }, [users]);
+}
+
+// Component only handles rendering
+function UserDashboard() {
+  const { data: users, isLoading } = useUsers();
+  const sortedUsers = useActiveUsersSorted(users);
+
+  if (isLoading) return <LoadingSpinner />;
+
+  return <div>{/* Render sortedUsers */}</div>;
+}
+```
+
+**Key Takeaway:**
+- **Separate concerns: data fetching, business logic, rendering**
+- Extract logic to custom hooks
+- Keep components focused on UI
+
+---
+
+## 6. Provider Architecture
+
+### Pitfall 6.1: Wrong Provider Order
+
+**❌ WRONG:**
+```typescript
+// AuthInitializer outside AuthProvider ❌
+function RootLayout({ children }) {
+  return (
+    <Providers>
+      <AuthInitializer />  {/* Can't access auth context! */}
+      <AuthProvider>
+        {children}
+      </AuthProvider>
+    </Providers>
+  );
+}
+```
+
+**✅ CORRECT:**
+```typescript
+function RootLayout({ children }) {
+  return (
+    <AuthProvider>           {/* Provider first */}
+      <AuthInitializer />    {/* Can access auth context */}
+      <Providers>
+        {children}
+      </Providers>
+    </AuthProvider>
+  );
+}
+```
+
+**Key Takeaway:**
+- **Providers must wrap components that use them**
+- Order matters when there are dependencies
+- Keep provider tree shallow (performance)
+
+---
+
+### Pitfall 6.2: Creating Too Many Providers
+
+**❌ WRONG:**
+```typescript
+// Separate provider for every piece of state ❌
+<UserProvider>
+  <ThemeProvider>
+    <LanguageProvider>
+      <NotificationProvider>
+        <SettingsProvider>
+          <App />
+        </SettingsProvider>
+      </NotificationProvider>
+    </LanguageProvider>
+  </ThemeProvider>
+</UserProvider>
+```
+
+**✅ BETTER:**
+```typescript
+// Combine related state, use Zustand for most things
+<AuthProvider>         {/* Only for auth DI */}
+  <ThemeProvider>      {/* Built-in from lib */}
+    <QueryClientProvider>  {/* React Query */}
+      <App />
+    </QueryClientProvider>
+  </ThemeProvider>
+</AuthProvider>
+
+// Most other state in Zustand stores (no providers needed)
+const useUIStore = create(...);  // Theme, sidebar, modals
+const useUserPreferences = create(...);  // User settings
+```
+
+**Key Takeaway:**
+- **Use Context only when necessary** (DI, third-party integrations)
+- **Use Zustand for most global state** (no provider needed)
+- Avoid provider hell
+
+---
+
+## 7. Event Handlers & Callbacks
+
+### Pitfall 7.1: Using Hooks in Event Handlers
+
+**❌ WRONG:**
+```typescript
+function MyComponent() {
+  const handleClick = () => {
+    const { user } = useAuth();  // ❌ Hook called in callback!
+    console.log(user);
+  };
+
+  return <button onClick={handleClick}>Click</button>;
+}
+```
+
+**✅ CORRECT:**
+```typescript
+function MyComponent() {
+  const { user } = useAuth();  // ✅ Hook at component top level
+
+  const handleClick = () => {
+    console.log(user);  // Access from closure
+  };
+
+  return <button onClick={handleClick}>Click</button>;
+}
+
+// OR for mutations, use getState()
+function MyComponent() {
+  const handleLogout = async () => {
+    const clearAuth = useAuthStore.getState().clearAuth;  // ✅ Not a hook call
+    await clearAuth();
+  };
+
+  return <button onClick={handleLogout}>Logout</button>;
+}
+```
+
+**Key Takeaway:**
+- **Never call hooks inside event handlers**
+- For render state: Call hook at top level, access in closure
+- For mutations: Use `store.getState().method()`
+
+---
+
+### Pitfall 7.2: Not Handling Async Errors in Event Handlers
+
+**❌ WRONG:**
+```typescript
+const handleSubmit = async (data: FormData) => {
+  await apiCall(data);  // ❌ No error handling!
+};
+```
+
+**✅ CORRECT:**
+```typescript
+const handleSubmit = async (data: FormData) => {
+  try {
+    await apiCall(data);
+    toast.success('Success!');
+  } catch (error) {
+    console.error('Failed to submit:', error);
+    toast.error('Failed to submit form');
+  }
+};
+```
+
+**Key Takeaway:**
+- **Always wrap async calls in try/catch**
+- Provide user feedback for both success and errors
+- Log errors for debugging
+
+---
+
+## 8. Testing Pitfalls
+
+### Pitfall 8.1: Not Mocking Context Providers in Tests
+
+**❌ WRONG:**
+```typescript
+// Test without provider ❌
+test('renders user name', () => {
+  render(<UserProfile />);  // Will crash - no AuthProvider!
+  expect(screen.getByText('John')).toBeInTheDocument();
+});
+```
+
+**✅ CORRECT:**
+```typescript
+// Mock the hook
+jest.mock('@/lib/stores', () => ({
+  useAuth: jest.fn(),
+}));
+
+test('renders user name', () => {
+  (useAuth as jest.Mock).mockReturnValue({
+    user: { id: '1', name: 'John' },
+    isAuthenticated: true,
+  });
+
+  render(<UserProfile />);
+  expect(screen.getByText('John')).toBeInTheDocument();
+});
+```
+
+**Key Takeaway:**
+- **Mock hooks at module level in tests**
+- Provide necessary return values for each test case
+- Test both success and error states
+
+---
+
+### Pitfall 8.2: Testing Implementation Details
+
+**❌ WRONG:**
+```typescript
+test('calls useAuthStore hook', () => {
+  const spy = jest.spyOn(require('@/lib/stores'), 'useAuthStore');
+  render(<MyComponent />);
+  expect(spy).toHaveBeenCalled();  // ❌ Testing implementation!
+});
+```
+
+**✅ CORRECT:**
+```typescript
+test('displays user name when authenticated', () => {
+  (useAuth as jest.Mock).mockReturnValue({
+    user: { name: 'John' },
+    isAuthenticated: true,
+  });
+
+  render(<MyComponent />);
+  expect(screen.getByText('John')).toBeInTheDocument();  // ✅ Testing behavior!
+});
+```
+
+**Key Takeaway:**
+- **Test behavior, not implementation**
+- Focus on what the user sees/does
+- Don't test internal API calls unless critical
+
+---
+
+## 9. Performance
+
+### Pitfall 9.1: Not Using React.memo for Expensive Components
+
+**❌ SUBOPTIMAL:**
+```typescript
+// Re-renders every time parent re-renders ❌
+function ExpensiveChart({ data }) {
+  // Heavy computation/rendering
+  return <ComplexVisualization data={data} />;
+}
+```
+
+**✅ OPTIMIZED:**
+```typescript
+// Only re-renders when data changes ✅
+export const ExpensiveChart = React.memo(function ExpensiveChart({ data }) {
+  return <ComplexVisualization data={data} />;
+});
+```
+
+**Key Takeaway:**
+- **Use `React.memo` for expensive components**
+- Especially useful for list items, charts, heavy UI
+- Profile with React DevTools to identify candidates
+
+---
+
+### Pitfall 9.2: Creating Functions Inside Render
+
+**❌ SUBOPTIMAL:**
+```typescript
+function MyComponent() {
+  return (
+    <button onClick={() => console.log('clicked')}>  {/* New function every render */}
+      Click
+    </button>
+  );
+}
+```
+
+**✅ OPTIMIZED:**
+```typescript
+function MyComponent() {
+  const handleClick = useCallback(() => {
+    console.log('clicked');
+  }, []);
+
+  return <button onClick={handleClick}>Click</button>;
+}
+```
+
+**When to Optimize:**
+- **For memoized child components** (memo, PureComponent)
+- **For expensive event handlers**
+- **When profiling shows performance issues**
+
+**When NOT to optimize:**
+- **Simple components with cheap operations** (premature optimization)
+- **One-off event handlers**
+
+**Key Takeaway:**
+- **Use `useCallback` for functions passed to memoized children**
+- But don't optimize everything - profile first
+
+---
+
+## 10. Import/Export Patterns
+
+### Pitfall 10.1: Not Using Barrel Exports
+
+**❌ INCONSISTENT:**
+```typescript
+// Deep imports all over the codebase
+import { useAuth } from '@/lib/auth/AuthContext';
+import { useAuthStore } from '@/lib/stores/authStore';
+import { User } from '@/lib/stores/authStore';
+```
+
+**✅ CONSISTENT:**
+```typescript
+// Barrel exports in stores/index.ts
+export { useAuth, AuthProvider } from '../auth/AuthContext';
+export { useAuthStore, type User } from './authStore';
+
+// Clean imports everywhere
+import { useAuth, useAuthStore, User } from '@/lib/stores';
+```
+
+**Key Takeaway:**
+- **Create barrel exports (index.ts) for public APIs**
+- Easier to refactor internal structure
+- Consistent import paths across codebase
+
+---
+
+### Pitfall 10.2: Circular Dependencies
+
+**❌ WRONG:**
+```typescript
+// fileA.ts
+import { functionB } from './fileB';
+export function functionA() { return functionB(); }
+
+// fileB.ts
+import { functionA } from './fileA';  // ❌ Circular!
+export function functionB() { return functionA(); }
+```
+
+**✅ CORRECT:**
+```typescript
+// utils.ts
+export function sharedFunction() { /* shared logic */ }
+
+// fileA.ts
+import { sharedFunction } from './utils';
+export function functionA() { return sharedFunction(); }
+
+// fileB.ts
+import { sharedFunction } from './utils';
+export function functionB() { return sharedFunction(); }
+```
+
+**Key Takeaway:**
+- **Avoid circular imports**
+- Extract shared code to separate modules
+- Keep dependency graph acyclic
+
+---
+
+## Verification Checklist
+
+Before committing code, always run:
+
+```bash
+# Type checking
+npm run type-check
+
+# Linting
+npm run lint
+
+# Tests
+npm test
+
+# Build check
+npm run build
+```
+
+**In browser:**
+- [ ] No console errors or warnings
+- [ ] Components render correctly
+- [ ] No infinite loops or excessive re-renders (React DevTools)
+- [ ] Proper error handling (test error states)
