Refactor metadata handling for improved maintainability and localization support

- Extracted server-only metadata generation logic into separate files, reducing inline logic in page components.
- Added `/* istanbul ignore file */` annotations for E2E-covered framework-level metadata.
- Standardized `generateMetadata` export patterns across auth, admin, and error pages for consistency.
- Enhanced maintainability and readability by centralizing metadata definitions for each route.

+
+## Critical Implementation Notes
+
+### Authentication Flow
+- **JWT-based**: Access tokens (15 min) + refresh tokens (7 days)
+- **Session tracking**: Database-backed with device info, IP, user agent
+- **Token refresh**: Validates JTI in database, not just JWT signature
+- **Authorization**: FastAPI dependencies in `api/dependencies/auth.py`
+  - `get_current_user`: Requires valid access token
+  - `get_current_active_user`: Requires active account
+  - `get_optional_current_user`: Accepts authenticated or anonymous
+  - `get_current_superuser`: Requires superuser flag
+
+### Database Pattern
+- **Async SQLAlchemy 2.0** with PostgreSQL
+- **Connection pooling**: 20 base connections, 50 max overflow
+- **CRUD base class**: `crud/base.py` with common operations
+- **Migrations**: Alembic with helper script `migrate.py`
+  - `python migrate.py auto "message"` - Generate and apply
+  - `python migrate.py list` - View history
+
+### Frontend State Management
+- **Zustand stores**: Lightweight state management
+- **TanStack Query**: API data fetching/caching
+- **Auto-generated client**: From OpenAPI spec via `npm run generate:api`
+- **Dependency Injection**: ALWAYS use `useAuth()` from `AuthContext`, NEVER import `useAuthStore` directly
+
+### Internationalization (i18n)
+- **next-intl v4**: Type-safe internationalization library
+- **Locale routing**: `/en/*`, `/it/*` (English and Italian supported)
+- **Translation files**: `frontend/messages/en.json`, `frontend/messages/it.json`
+- **LocaleSwitcher**: Component for seamless language switching
+- **SEO-friendly**: Locale-aware metadata, sitemaps, and robots.txt
+- **Type safety**: Full TypeScript support for translations
+- **Utilities**: `frontend/src/lib/i18n/` (metadata, routing, utils)
+
+### Organization System
+Three-tier RBAC:
+- **Owner**: Full control (delete org, manage all members)
+- **Admin**: Add/remove members, assign admin role (not owner)
+- **Member**: Read-only organization access
+
+Permission dependencies in `api/dependencies/permissions.py`:
+- `require_organization_owner`
+- `require_organization_admin`
+- `require_organization_member`
+- `can_manage_organization_member`
+
+### Testing Infrastructure
+
+**Backend (pytest):**
+- 97% coverage, 743 tests
+- Security-focused: JWT attacks, session hijacking, privilege escalation
+- Async fixtures in `tests/conftest.py`
+- Run: `IS_TEST=True uv run pytest`
+- Coverage: `IS_TEST=True uv run pytest --cov=app --cov-report=term-missing`
+
+**Frontend Unit Tests (Jest):**
+- 97% coverage
+- Component, hook, and utility testing
+- Run: `npm test`
+- Coverage: `npm run test:coverage`
+
+**E2E Tests (Playwright):**
+- 56 passing, 1 skipped (zero flaky tests)
+- Complete user flows (auth, navigation, settings)
+- Run: `npm run test:e2e`
+- UI mode: `npm run test:e2e:ui`
+
+### Development Tooling
+
+**Backend:**
+- **uv**: Modern Python package manager (10-100x faster than pip)
+- **Ruff**: All-in-one linting/formatting (replaces Black, Flake8, isort)
+- **mypy**: Type checking with Pydantic plugin
+- **Makefile**: `make help` for all commands
+
+**Frontend:**
+- **Next.js 15**: App Router with React 19
+- **TypeScript**: Full type safety
+- **TailwindCSS + shadcn/ui**: Design system
+- **ESLint + Prettier**: Code quality
+
+### Environment Configuration
+
+**Backend** (`.env`):
+```bash
+POSTGRES_USER=postgres
+POSTGRES_PASSWORD=your_password
+POSTGRES_HOST=db
+POSTGRES_PORT=5432
+POSTGRES_DB=app
+
+SECRET_KEY=your-secret-key-min-32-chars
+ENVIRONMENT=development|production
+CSP_MODE=relaxed|strict|disabled
+
+FIRST_SUPERUSER_EMAIL=admin@example.com
+FIRST_SUPERUSER_PASSWORD=admin123
+
+BACKEND_CORS_ORIGINS=["http://localhost:3000"]
+```
+
+**Frontend** (`.env.local`):
+```bash
+NEXT_PUBLIC_API_URL=http://localhost:8000/api/v1
+```
+
+## Common Development Workflows
+
+### Adding a New API Endpoint
+
+1. **Define schema** in `backend/app/schemas/`
+2. **Create CRUD operations** in `backend/app/crud/`
+3. **Implement route** in `backend/app/api/routes/`
+4. **Register router** in `backend/app/api/main.py`
+5. **Write tests** in `backend/tests/api/`
+6. **Generate frontend client**: `npm run generate:api`
+
+### Database Migrations
+
+```bash
+cd backend
+python migrate.py generate "description"  # Create migration
+python migrate.py apply                   # Apply migrations
+python migrate.py auto "description"      # Generate + apply
+```
+
+### Frontend Component Development
+
+1. **Create component** in `frontend/src/components/`
+2. **Follow design system** (see `frontend/docs/design-system/`)
+3. **Use dependency injection** for auth (`useAuth()` not `useAuthStore`)
+4. **Write tests** in `frontend/tests/` or `__tests__/`
+5. **Run type check**: `npm run type-check`
+
+## Security Features
+
+- **Password hashing**: bcrypt with salt rounds
+- **Rate limiting**: 60 req/min default, 10 req/min on auth endpoints
+- **Security headers**: CSP, X-Frame-Options, HSTS, etc.
+- **CSRF protection**: Built into FastAPI
+- **Session revocation**: Database-backed session tracking
+- **Comprehensive security tests**: JWT algorithm attacks, session hijacking, privilege escalation

-## Development Commands
-
-### Backend
-
-#### Setup
-
-**Dependencies are managed with [uv](https://docs.astral.sh/uv/) - the modern, fast Python package manager.**
-
-```bash
-cd backend
-
-# Install uv (if not already installed)
-curl -LsSf https://astral.sh/uv/install.sh | sh
-
-# Install all dependencies (production + dev) from uv.lock
-uv sync --extra dev
-
-# Or use the Makefile
-make install-dev
-```
-
-**Why uv?**
-- 🚀 10-100x faster than pip
-- 🔒 Reproducible builds with `uv.lock`
-- 📦 Modern dependency resolution
-- ⚡ Built by Astral (creators of Ruff)
-
-#### Database Migrations
-```bash
-# Using the migration helper (preferred)
-python migrate.py generate "migration message"  # Generate migration
-python migrate.py apply                         # Apply migrations
-python migrate.py auto "message"                # Generate and apply in one step
-python migrate.py list                          # List all migrations
-python migrate.py current                       # Show current revision
-python migrate.py check                         # Check DB connection
-
-# Or using Alembic directly
-alembic revision --autogenerate -m "message"
-alembic upgrade head
-```
-
-#### Testing
-
-**Test Coverage: High (comprehensive test suite)**
-- Security-focused testing with JWT algorithm attack prevention (CVE-2015-9235)
-- Session hijacking and privilege escalation tests included
-- Missing lines justified as defensive code, error handlers, and production-only code
-
-```bash
-# Run all tests (uses pytest-xdist for parallel execution)
-make test
-
-# Run with coverage report
-make test-cov
-
-# Or run directly with uv
-IS_TEST=True uv run pytest
-
-# Run specific test file
-IS_TEST=True uv run pytest tests/api/test_auth.py -v
-
-# Run single test
-IS_TEST=True uv run pytest tests/api/test_auth.py::TestLogin::test_login_success -v
-```
-
-**Available Make Commands:**
-```bash
-make help          # Show all available commands
-make install-dev   # Install all dependencies
-make validate      # Run lint + format + type checks
-make test          # Run tests
-make test-cov      # Run tests with coverage
-```
-
-#### Running Locally
-```bash
-cd backend
-uv run uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
-```
-
-### Frontend
-
-#### Setup
-```bash
-cd frontend
-npm install
-```
-
-#### Development
-```bash
-npm run dev          # Start dev server on http://localhost:3000
-npm run build        # Production build
-npm run lint         # ESLint
-npm run type-check   # TypeScript checking
-```
-
-#### Testing
-```bash
-# Unit tests (Jest)
-npm test                    # Run all unit tests
-npm run test:watch          # Watch mode
-npm run test:coverage       # With coverage
-
-# E2E tests (Playwright)
-npm run test:e2e            # Run all E2E tests
-npm run test:e2e:ui         # Open Playwright UI
-npm run test:e2e:debug      # Debug mode
-npx playwright test auth-login.spec.ts  # Run specific file
-```
-
-**E2E Test Best Practices:**
-- Use `Promise.all()` pattern for Next.js Link navigation:
-  ```typescript
-  await Promise.all([
-    page.waitForURL('/target', { timeout: 10000 }),
-    link.click()
-  ]);
-  ```
-- Use ID-based selectors for validation errors (e.g., `#email-error`)
-- Error IDs use dashes not underscores (`#new-password-error`)
-- Target `.border-destructive[role="alert"]` to avoid Next.js route announcer conflicts
-- Uses 12 workers in non-CI mode (`workers: 12` in `playwright.config.ts`)
-- URL assertions should use regex to handle query params: `/\/auth\/login/`

-### Docker
-
-```bash
-# Development (with hot reload)
-docker-compose -f docker-compose.dev.yml up
-
-# Production
-docker-compose up -d
-
-# Rebuild specific service
-docker-compose build backend
-docker-compose build frontend
-```
-
-## Key Architectural Patterns
-
-### Authentication Flow
-1. **Login**: `POST /api/v1/auth/login` returns access + refresh tokens
-   - Access token: 15 minutes expiry (JWT)
-   - Refresh token: 7 days expiry (JWT with JTI stored in DB)
-   - Session tracking with device info (IP, user agent, device ID)
-
-2. **Token Refresh**: `POST /api/v1/auth/refresh` validates refresh token JTI
-   - Checks session is active in database
-   - Issues new access token (refresh token remains valid)
-   - Updates session `last_used_at`
-
-3. **Authorization**: FastAPI dependencies in `api/dependencies/auth.py`
-   - `get_current_user`: Validates access token, returns User (raises 401 if invalid)
-   - `get_current_active_user`: Requires valid access token + active account
-   - `get_optional_current_user`: Accepts both authenticated and anonymous users (returns User or None)
-   - `get_current_superuser`: Requires superuser flag
-
-### Database Pattern: Async SQLAlchemy
-- **Engine**: Created in `core/database.py` with connection pooling
-- **Sessions**: AsyncSession from `async_sessionmaker`
-- **CRUD**: Base class in `crud/base.py` with common operations
-  - Inherits: `CRUDUser`, `CRUDSession`, `CRUDOrganization`
-  - Pattern: `async def get(db: AsyncSession, id: str) -> Model | None`
-
-### Frontend State Management
-- **Zustand stores**: `lib/stores/` (authStore, etc.)
-- **TanStack Query**: API data fetching/caching
-- **Auto-generated client**: `lib/api/generated/` from OpenAPI spec
-  - Generate with: `npm run generate:api` (runs `scripts/generate-api-client.sh`)
+**Testing Commands:**
+- Backend: `IS_TEST=True uv run pytest` (always prefix with `IS_TEST=True`)
+- Frontend unit: `npm test`
+- Frontend E2E: `npm run test:e2e`
+- Use `make test` or `make test-cov` in backend for convenience

@@ -254,41 +80,54 @@ const { user, isAuthenticated } = useAuth();
 
 **See**: `frontend/docs/ARCHITECTURE_FIX_REPORT.md` for full details.
 
-### Session Management Architecture
-**Database-backed session tracking** (not just JWT):
-- Each refresh token has a corresponding `UserSession` record
-- Tracks: device info, IP, location, last used timestamp
-- Supports session revocation (logout from specific devices)
-- Cleanup job removes expired sessions
+### E2E Test Best Practices
 
-### Permission System
-Three-tier organization roles:
-- **Owner**: Full control (delete org, manage all members)
-- **Admin**: Can add/remove members, assign admin role (not owner)
-- **Member**: Read-only organization access
+When writing or fixing Playwright tests:
 
-Dependencies in `api/dependencies/permissions.py`:
-- `require_organization_owner`
-- `require_organization_admin`
-- `require_organization_member`
-- `can_manage_organization_member` (owner or admin, but not self-demotion)
+**Navigation Pattern:**
+```typescript
+// ✅ CORRECT - Use Promise.all for Next.js Link clicks
+await Promise.all([
+  page.waitForURL('/target', { timeout: 10000 }),
+  link.click()
+]);
+```
 
-## Testing Infrastructure
+**Selectors:**
+- Use ID-based selectors for validation errors: `#email-error`
+- Error IDs use dashes not underscores: `#new-password-error`
+- Target `.border-destructive[role="alert"]` to avoid Next.js route announcer conflicts
+- Avoid generic `[role="alert"]` which matches multiple elements
 
-### Backend Test Patterns
+**URL Assertions:**
+```typescript
+// ✅ Use regex to handle query params
+await expect(page).toHaveURL(/\/auth\/login/);
 
-**Fixtures** (in `tests/conftest.py`):
-- `async_test_db`: Fresh SQLite in-memory database per test
-- `client`: AsyncClient with test database override
-- `async_test_user`: Pre-created regular user
-- `async_test_superuser`: Pre-created superuser
-- `user_token` / `superuser_token`: Access tokens for API calls
+// ❌ Don't use exact strings (fails with query params)
+await expect(page).toHaveURL('/auth/login');
+```
 
-**Database Mocking for Exception Testing**:
+**Configuration:**
+- Uses 12 workers in non-CI mode (`playwright.config.ts`)
+- Reduces to 2 workers in CI for stability
+- Tests are designed to be non-flaky with proper waits
+
+### Important Implementation Details
+
+**Authentication Testing:**
+- Backend fixtures in `tests/conftest.py`:
+  - `async_test_db`: Fresh SQLite per test
+  - `async_test_user` / `async_test_superuser`: Pre-created users
+  - `user_token` / `superuser_token`: Access tokens for API calls
+- Always use `@pytest.mark.asyncio` for async tests
+- Use `@pytest_asyncio.fixture` for async fixtures

-### Rate Limiting
-- Implemented with `slowapi`
-- Default: 60 requests/minute per IP
-- Applied to auth endpoints (login, register, password reset)
-- Override in route decorators: `@limiter.limit("10/minute")`
-
-## Common Workflows
-
-### Adding a New API Endpoint
-
-1. **Create schema** (`backend/app/schemas/`):
-   ```python
-   class ItemCreate(BaseModel):
-       name: str
-       description: Optional[str] = None
-
-   class ItemResponse(BaseModel):
-       id: UUID
-       name: str
-       created_at: datetime
-   ```
-
-2. **Create CRUD operations** (`backend/app/crud/`):
-   ```python
-   class CRUDItem(CRUDBase[Item, ItemCreate, ItemUpdate]):
-       async def get_by_name(self, db: AsyncSession, name: str) -> Item | None:
-           result = await db.execute(select(Item).where(Item.name == name))
-           return result.scalar_one_or_none()
-
-   item = CRUDItem(Item)
-   ```
-
-3. **Create route** (`backend/app/api/routes/items.py`):
-   ```python
-   from app.api.dependencies.auth import get_current_user
-
-   @router.post("/", response_model=ItemResponse)
-   async def create_item(
-       item_in: ItemCreate,
-       current_user: User = Depends(get_current_user),
-       db: AsyncSession = Depends(get_db)
-   ):
-       item = await item_crud.create(db, obj_in=item_in)
-       return item
-   ```
-
-4. **Register router** (`backend/app/api/main.py`):
-   ```python
-   from app.api.routes import items
-   api_router.include_router(items.router, prefix="/items", tags=["Items"])
-   ```
-
-5. **Write tests** (`backend/tests/api/test_items.py`):
-   ```python
-   @pytest.mark.asyncio
-   async def test_create_item(client, user_token):
-       response = await client.post(
-           "/api/v1/items",
-           headers={"Authorization": f"Bearer {user_token}"},
-           json={"name": "Test Item"}
-       )
-       assert response.status_code == 201
-   ```
-
-6. **Generate frontend client**:
-   ```bash
-   cd frontend
-   npm run generate:api
-   ```
-
-### Adding a New React Component
-
-1. **Create component** (`frontend/src/components/`):
-   ```typescript
-   export function MyComponent() {
-     const { user } = useAuthStore();
-     return <div>Hello {user?.firstName}</div>;
-   }
-   ```
-
-2. **Add tests** (`frontend/src/components/__tests__/`):
-   ```typescript
-   import { render, screen } from '@testing-library/react';
-
-   test('renders component', () => {
-     render(<MyComponent />);
-     expect(screen.getByText(/Hello/)).toBeInTheDocument();
-   });
-   ```
-
-3. **Add to page** (`frontend/src/app/page.tsx`):
-   ```typescript
-   import { MyComponent } from '@/components/MyComponent';
-
-   export default function Page() {
-     return <MyComponent />;
-   }
-   ```
-
-## Development Tooling Stack
-
-**State-of-the-art Python tooling (Nov 2025):**
-
-### Dependency Management: uv
-- **Fast**: 10-100x faster than pip
-- **Reliable**: Reproducible builds with `uv.lock` lockfile
-- **Modern**: Built by Astral (Ruff creators) in Rust
-- **Commands**:
-  - `make install-dev` - Install all dependencies
-  - `make sync` - Sync from lockfile
-  - `uv add <package>` - Add new dependency
-  - `uv add --dev <package>` - Add dev dependency
-
-### Code Quality: Ruff + mypy
-- **Ruff**: All-in-one linting, formatting, and import sorting
-  - Replaces: Black, Flake8, isort
-  - **10-100x faster** than alternatives
-  - `make lint`, `make format`, `make validate`
-- **mypy**: Type checking with Pydantic plugin
-  - Gradual typing approach
-  - Strategic per-module configurations
-
-### Configuration: pyproject.toml
-- Single source of truth for all tools
-- Dependencies defined in `[project.dependencies]`
-- Dev dependencies in `[project.optional-dependencies]`
-- Tool configs: Ruff, mypy, pytest, coverage
-
-## Current Project Status (Nov 2025)

-
-## Email Service Integration
-
-The project includes a **placeholder email service** (`backend/app/services/email_service.py`) designed for easy integration with production email providers.
-
-### Current Implementation
-
-**Console Backend (Default)**:
-- Logs email content to console/logs instead of sending
-- Safe for development and testing
-- No external dependencies required
-
-### Production Integration
-
-To enable email functionality, implement one of these approaches:
-
-**Option 1: SMTP Integration** (Recommended for most use cases)
-```python
-# In app/services/email_service.py, complete the SMTPEmailBackend implementation
-from aiosmtplib import SMTP
-from email.mime.text import MIMEText
-from email.mime.multipart import MIMEMultipart
-
-# Add environment variables to .env:
-# SMTP_HOST=smtp.gmail.com
-# SMTP_PORT=587
-# SMTP_USERNAME=your-email@gmail.com
-# SMTP_PASSWORD=your-app-password
-```
-
-**Option 2: Third-Party Service** (SendGrid, AWS SES, Mailgun, etc.)
-```python
-# Create a new backend class, e.g., SendGridEmailBackend
-class SendGridEmailBackend(EmailBackend):
-    def __init__(self, api_key: str):
-        self.api_key = api_key
-        self.client = sendgrid.SendGridAPIClient(api_key)
-
-    async def send_email(self, to, subject, html_content, text_content=None):
-        # Implement SendGrid sending logic
-        pass
-
-# Update global instance in email_service.py:
-# email_service = EmailService(SendGridEmailBackend(settings.SENDGRID_API_KEY))
-```
-
-**Option 3: External Microservice**
-- Use a dedicated email microservice via HTTP API
-- Implement `HTTPEmailBackend` that makes async HTTP requests
-
-### Email Templates Included
-
-The service includes pre-built templates for:
-- **Password Reset**: `send_password_reset_email()` - 1 hour expiry
-- **Email Verification**: `send_email_verification()` - 24 hour expiry
-
-Both include responsive HTML and plain text versions.
-
-### Integration Points
-
-Email sending is called from:
-- `app/api/routes/auth.py` - Password reset flow (placeholder comments)
-- Registration flow - Ready for email verification integration
-
-**Note**: Current auth routes have placeholder comments where email functionality should be integrated. Search for "TODO: Send email" in the codebase.
-
-## API Documentation
-
-Once backend is running:
-- **Swagger UI**: http://localhost:8000/docs
-- **ReDoc**: http://localhost:8000/redoc
-- **OpenAPI JSON**: http://localhost:8000/api/v1/openapi.json
-
-## Troubleshooting
-
-### Tests failing with "Module was never imported"
-Run with single process: `pytest -n 0`
-
-### Coverage not improving despite new tests
-- Verify tests actually execute endpoints (check response.status_code)
-- Generate HTML coverage: `pytest --cov=app --cov-report=html -n 0`
-- Check for dependency override issues in test fixtures
-
-### Frontend type errors
-```bash
-npm run type-check          # Check all types
-npx tsc --noEmit           # Same but shorter
-```
-
-### E2E tests flaking
-- Check worker count (should be 4, not 16+)
-- Use `Promise.all()` for navigation
-- Use regex for URL assertions
-- Target specific selectors (avoid generic `[role="alert"]`)
-
-### Database migration conflicts
-```bash
-python migrate.py list      # Check migration history
-alembic downgrade -1        # Downgrade one revision
-alembic upgrade head        # Re-apply
-```

+**Frontend Component Development:**
+- Follow design system docs in `frontend/docs/design-system/`
+- Read `08-ai-guidelines.md` for AI code generation rules
+- Use parent-controlled spacing (see `04-spacing-philosophy.md`)
+- WCAG AA compliance required (see `07-accessibility.md`)
+
+**Security Considerations:**
+- Backend has comprehensive security tests (JWT attacks, session hijacking)
+- Never skip security headers in production
+- Rate limiting is configured in route decorators: `@limiter.limit("10/minute")`
+- Session revocation is database-backed, not just JWT expiry
+
+### Common Workflows Guidance
+
+**When Adding a New Feature:**
+1. Start with backend schema and CRUD
+2. Implement API route with proper authorization
+3. Write backend tests (aim for >90% coverage)
+4. Generate frontend API client: `npm run generate:api`
+5. Implement frontend components
+6. Write frontend unit tests
+7. Add E2E tests for critical flows
+8. Update relevant documentation
+
+**When Fixing Tests:**
+- Backend: Check test database isolation and async fixture usage
+- Frontend unit: Verify mocking of `useAuth()` not `useAuthStore`
+- E2E: Use `Promise.all()` pattern and regex URL assertions
+
+**When Debugging:**
+- Backend: Check `IS_TEST=True` environment variable is set
+- Frontend: Run `npm run type-check` first
+- E2E: Use `npm run test:e2e:debug` for step-by-step debugging
+- Check logs: Backend has detailed error logging
+
+### Tool Usage Preferences
+
+**Prefer specialized tools over bash:**
+- Use Read/Write/Edit tools for file operations
+- Never use `cat`, `echo >`, or heredoc for file manipulation
+- Use Task tool with `subagent_type=Explore` for codebase exploration
+- Use Grep tool for code search, not bash `grep`
+
+**When to use parallel tool calls:**
+- Independent git commands: `git status`, `git diff`, `git log`
+- Reading multiple unrelated files
+- Running multiple test suites simultaneously
+- Independent validation steps
+
+## Custom Skills
+
+No Claude Code Skills installed yet. To create one, invoke the built-in "skill-creator" skill.
+
+**Potential skill ideas for this project:**
+- API endpoint generator workflow (schema → CRUD → route → tests → frontend client)
+- Component generator with design system compliance
+- Database migration troubleshooting helper
+- Test coverage analyzer and improvement suggester
+- E2E test generator for new features

----
-
-## Overview
-
-### Why Combined Coverage?
-
-Your project uses a **dual testing strategy**:
-
-- **Jest (Unit tests):** 97%+ coverage, excludes browser-specific code
-- **Playwright (E2E tests):** Tests excluded files (layouts, API hooks, error boundaries)
-
-**Combined coverage** shows the full picture by merging both coverage sources.
-
-### Current Exclusions from Jest
-
-```javascript
-// From jest.config.js - These ARE tested by E2E:
-'!src/lib/api/hooks/**',        // React Query hooks
-'!src/app/**/layout.tsx',        // Next.js layouts
-'!src/app/**/error.tsx',         // Error boundaries
-'!src/app/**/loading.tsx',       // Loading states
-```
-
-### Expected Results
-
-```
-Unit test coverage:     97.19% (excluding above)
-E2E coverage:          ~25-35% (user flows + excluded files)
-Combined coverage:     98-100% ✅
-```
-
----
-
-## Quick Start
-
-### Prerequisites
-
-All infrastructure is already created! Just need dependencies:
-
-```bash
-# Option 1: V8 Coverage (Chromium only, no instrumentation)
-npm install -D v8-to-istanbul istanbul-lib-coverage istanbul-lib-report istanbul-reports
-
-# Option 2: Istanbul Instrumentation (all browsers)
-npm install -D @istanbuljs/nyc-config-typescript babel-plugin-istanbul nyc \
-               istanbul-lib-coverage istanbul-lib-report istanbul-reports
-```
-
-### Add Package Scripts
-
-Add to `package.json`:
-
-```json
-{
-  "scripts": {
-    "coverage:convert": "tsx scripts/convert-v8-to-istanbul.ts",
-    "coverage:merge": "tsx scripts/merge-coverage.ts",
-    "coverage:combined": "npm run test:coverage && E2E_COVERAGE=true npm run test:e2e && npm run coverage:convert && npm run coverage:merge",
-    "coverage:view": "open coverage-combined/index.html"
-  }
-}
-```
-
-### Run Combined Coverage
-
-```bash
-# Full workflow (unit + E2E + merge)
-npm run coverage:combined
-
-# View HTML report
-npm run coverage:view
-```
-
----
-
-## Approach 1: V8 Coverage (Recommended)
-
-### Pros & Cons
-
-**Pros:**
-
-- ✅ Native browser coverage (most accurate)
-- ✅ No build instrumentation needed (faster)
-- ✅ Works with source maps
-- ✅ Zero performance overhead
-
-**Cons:**
-
-- ❌ Chromium only (V8 engine specific)
-- ❌ Requires v8-to-istanbul conversion
-
-### Setup Steps
-
-#### 1. Install Dependencies
-
-```bash
-npm install -D v8-to-istanbul istanbul-lib-coverage istanbul-lib-report istanbul-reports
-```
-
-#### 2. Integrate into E2E Tests
-
-Update your E2E test files to use coverage helpers:
-
-```typescript
-// e2e/homepage.spec.ts
-import { test, expect } from '@playwright/test';
-import { withCoverage } from './helpers/coverage';
-
-test.describe('Homepage Tests', () => {
-  test.beforeEach(async ({ page }) => {
-    // Start coverage collection
-    await withCoverage.start(page);
-    await page.goto('/');
-  });
-
-  test.afterEach(async ({ page }, testInfo) => {
-    // Stop and save coverage
-    await withCoverage.stop(page, testInfo.title);
-  });
-
-  test('displays header', async ({ page }) => {
-    await expect(page.getByRole('heading')).toBeVisible();
-  });
-});
-```
-
-#### 3. Run E2E Tests with Coverage
-
-```bash
-E2E_COVERAGE=true npm run test:e2e
-```
-
-This generates: `coverage-e2e/raw/*.json` (V8 format)
-
-#### 4. Convert V8 to Istanbul
-
-```bash
-npm run coverage:convert
-```
-
-This converts to: `coverage-e2e/.nyc_output/e2e-coverage.json` (Istanbul format)
-
-#### 5. Merge with Jest Coverage
-
-```bash
-npm run coverage:merge
-```
-
-This generates: `coverage-combined/index.html`

-## Approach 2: Istanbul Instrumentation
-
-### Pros & Cons
-
-**Pros:**
-
-- ✅ Works on all browsers (Firefox, Safari, etc.)
-- ✅ Industry standard tooling
-- ✅ No conversion needed
-
-**Cons:**
-
-- ❌ Requires code instrumentation (slower builds)
-- ❌ More complex setup
-- ❌ Slight test performance overhead
-
-### Setup Steps
-
-#### 1. Install Dependencies
-
-```bash
-npm install -D @istanbuljs/nyc-config-typescript babel-plugin-istanbul \
-               nyc istanbul-lib-coverage istanbul-lib-report istanbul-reports \
-               @babel/core babel-loader
-```
-
-#### 2. Configure Babel Instrumentation
-
-Create `.babelrc.js`:
-
-```javascript
-module.exports = {
-  presets: ['next/babel'],
-  env: {
-    test: {
-      plugins: [process.env.E2E_COVERAGE && 'istanbul'].filter(Boolean),
-    },
-  },
-};
-```
-
-#### 3. Configure Next.js Webpack
-
-Update `next.config.js`:
-
-```javascript
-const nextConfig = {
-  webpack: (config, { isServer }) => {
-    // Add Istanbul instrumentation in E2E coverage mode
-    if (process.env.E2E_COVERAGE && !isServer) {
-      config.module.rules.push({
-        test: /\.(js|jsx|ts|tsx)$/,
-        exclude: /node_modules/,
-        use: {
-          loader: 'babel-loader',
-          options: {
-            presets: ['next/babel'],
-            plugins: ['istanbul'],
-          },
-        },
-      });
-    }
-    return config;
-  },
-};
-
-module.exports = nextConfig;
-```
-
-#### 4. Integrate into E2E Tests
-
-Use the Istanbul helper instead:
-
-```typescript
-import { test, expect } from '@playwright/test';
-import { saveIstanbulCoverage } from './helpers/coverage';
-
-test.describe('Homepage Tests', () => {
-  test.afterEach(async ({ page }, testInfo) => {
-    await saveIstanbulCoverage(page, testInfo.title);
-  });
-
-  test('my test', async ({ page }) => {
-    await page.goto('/');
-    // Test code...
-  });
-});
-```
-
-#### 5. Run Tests
-
-```bash
-# Start dev server with instrumentation
-E2E_COVERAGE=true npm run dev
-
-# In another terminal, run E2E tests
-E2E_COVERAGE=true npm run test:e2e
-```
-
-#### 6. Merge Coverage
-
-```bash
-npm run coverage:merge
-```
-
-No conversion step needed! Istanbul coverage goes directly to `.nyc_output/`.

-
-## Integration Steps
-
-### Phase 1: Pilot Integration (Single Test File)
-
-Start with one E2E test file to verify the setup:
-
-**File: `e2e/homepage.spec.ts`**
-
-```typescript
-import { test, expect } from '@playwright/test';
-import { withCoverage } from './helpers/coverage';
-
-test.describe('Homepage - Desktop Navigation', () => {
-  test.beforeEach(async ({ page }) => {
-    await withCoverage.start(page);
-    await page.goto('/');
-    await page.waitForLoadState('networkidle');
-  });
-
-  test.afterEach(async ({ page }, testInfo) => {
-    await withCoverage.stop(page, testInfo.title);
-  });
-
-  test('should display header with logo and navigation', async ({ page }) => {
-    await expect(page.getByRole('link', { name: /FastNext/i })).toBeVisible();
-    await expect(page.getByRole('link', { name: 'Components' })).toBeVisible();
-  });
-});
-```
-
-**Test the pilot:**
-
-```bash
-# Install dependencies
-npm install -D v8-to-istanbul istanbul-lib-coverage istanbul-lib-report istanbul-reports
-
-# Run single test with coverage
-E2E_COVERAGE=true npx playwright test homepage.spec.ts
-
-# Verify coverage files created
-ls coverage-e2e/raw/
-
-# Convert and merge
-npm run coverage:convert
-npm run coverage:merge
-
-# Check results
-npm run coverage:view
-```
-
-### Phase 2: Rollout to All Tests
-
-Once pilot works, update all 15 E2E spec files:
-
-**Automated rollout script:**
-
-```bash
-# Create a helper script: scripts/add-coverage-to-tests.sh
-#!/bin/bash
-
-for file in e2e/*.spec.ts; do
-  # Add import at top (if not already present)
-  if ! grep -q "import.*coverage" "$file"; then
-    sed -i "1i import { withCoverage } from './helpers/coverage';" "$file"
-  fi
-
-  # Add beforeEach hook (manual review recommended)
-  echo "Updated: $file"
-done
-```
-
-**Or manually add to each file:**
-
-1. Import coverage helper
-2. Add `beforeEach` with `withCoverage.start(page)`
-3. Add `afterEach` with `withCoverage.stop(page, testInfo.title)`
-
-### Phase 3: CI/CD Integration
-
-Add to your CI pipeline (e.g., `.github/workflows/test.yml`):
-
-```yaml
-- name: Run E2E tests with coverage
-  run: E2E_COVERAGE=true npm run test:e2e
-
-- name: Convert E2E coverage
-  run: npm run coverage:convert
-
-- name: Merge coverage
-  run: npm run coverage:merge
-
-- name: Upload combined coverage
-  uses: codecov/codecov-action@v3
-  with:
-    files: ./coverage-combined/lcov.info
-    flags: combined
-```
-
----
-
-## Troubleshooting
-
-### Problem: No coverage files generated
-
-**Symptoms:**
-
-```bash
-npm run coverage:convert
-# ❌ No V8 coverage found at: coverage-e2e/raw
-```
-
-**Solutions:**
-
-1. Verify `E2E_COVERAGE=true` is set when running tests
-2. Check coverage helpers are imported: `import { withCoverage } from './helpers/coverage'`
-3. Verify `beforeEach` and `afterEach` hooks are added
-4. Check browser console for errors during test run
-
-### Problem: V8 conversion fails
-
-**Symptoms:**
-
-```bash
-npm run coverage:convert
-# ❌ v8-to-istanbul not installed
-```
-
-**Solution:**
-
-```bash
-npm install -D v8-to-istanbul
-```
-
-### Problem: Coverage lower than expected
-
-**Symptoms:**
-
-```
-Combined: 85% (expected 99%)
-```
-
-**Causes & Solutions:**
-
-1. **E2E tests don't trigger all code paths**
-   - Check which files are E2E-only: `npm run coverage:merge` shows breakdown
-   - Add more E2E tests for uncovered scenarios
-
-2. **Source maps not working**
-   - Verify Next.js generates source maps: check `next.config.js`
-   - Istanbul needs source maps to map coverage back to source
-
-3. **Wrong files included**
-   - Check `.nycrc.json` includes correct patterns
-   - Verify excluded files match between Jest and NYC configs
-
-### Problem: Istanbul coverage is empty
-
-**Symptoms:**
-
-```typescript
-await saveIstanbulCoverage(page, testName);
-// ⚠️  No Istanbul coverage found
-```
-
-**Solutions:**
-
-1. Verify `babel-plugin-istanbul` is configured
-2. Check `window.__coverage__` exists:
-   ```typescript
-   const hasCoverage = await page.evaluate(() => !!(window as any).__coverage__);
-   console.log('Istanbul available:', hasCoverage);
-   ```
-3. Ensure dev server started with `E2E_COVERAGE=true npm run dev`
-
-### Problem: Merge script fails
-
-**Symptoms:**
-
-```bash
-npm run coverage:merge
-# ❌ Error: Cannot find module 'istanbul-lib-coverage'
-```
-
-**Solution:**
-
-```bash
-npm install -D istanbul-lib-coverage istanbul-lib-report istanbul-reports
-```
-

-
-## FAQ
-
-### Q: Should I use V8 or Istanbul coverage?
-
-**A: V8 coverage (Approach 1)** if:
-
-- ✅ You only test in Chromium
-- ✅ You want zero instrumentation overhead
-- ✅ You want the most accurate coverage
-
-**Istanbul (Approach 2)** if:
-
-- ✅ You need cross-browser coverage
-- ✅ You already use Istanbul tooling
-- ✅ You need complex coverage transformations
-
-### Q: Do I need to remove Jest exclusions?
-
-**A: No!** Keep them. The `.nycrc.json` config handles combined coverage independently.
-
-### Q: Will this slow down my tests?
-
-**V8 Approach:** Minimal overhead (~5% slower)
-**Istanbul Approach:** Moderate overhead (~15-20% slower due to instrumentation)
-
-### Q: Can I run coverage only for specific tests?
-
-**Yes:**
-
-```bash
-# Single file
-E2E_COVERAGE=true npx playwright test homepage.spec.ts
-
-# Specific describe block
-E2E_COVERAGE=true npx playwright test --grep "Mobile Menu"
-```
-
-### Q: How do I exclude files from E2E coverage?
-
-Edit `.nycrc.json` and add to `exclude` array:
-
-```json
-{
-  "exclude": ["src/app/dev/**", "src/lib/utils/debug.ts"]
-}
-```
-
-### Q: Can I see which lines are covered by E2E vs Unit tests?
-
-Not directly in the HTML report, but you can:
-
-1. Generate separate reports:
-
-   ```bash
-   npx nyc report --reporter=html --report-dir=coverage-unit --temp-dir=coverage/.nyc_output
-   npx nyc report --reporter=html --report-dir=coverage-e2e-only --temp-dir=coverage-e2e/.nyc_output
-   ```
-
-2. Compare the two reports to see differences
-
-### Q: What's the performance impact on CI?
-
-Typical impact:
-
-- V8 coverage: +2-3 minutes (conversion time)
-- Istanbul coverage: +5-7 minutes (build instrumentation)
-- Merge step: ~10 seconds
-
-Total CI time increase: **3-8 minutes**
-
----
-

-
-3. **Test with one E2E file** (homepage.spec.ts recommended)
-
-4. **Rollout to all E2E tests**
-
-5. **Add to CI/CD pipeline**
-
-### Expected Timeline
-
-- **Phase 1:** ✅ Done (non-disruptive infrastructure)

-# E2E Test Performance Optimization Plan
-
-**Current State**: 230 tests, ~2100 seconds total execution time
-**Target**: Reduce to <900 seconds (60% improvement)
-
-## Bottleneck Analysis
-
-### 1. Authentication Overhead (HIGHEST IMPACT)
-
-**Problem**: Each test logs in fresh via UI
-
-- **Impact**: 5-7s per test × 133 admin tests = ~700s wasted
-- **Root Cause**: Using `loginViaUI(page)` in every `beforeEach`
-
-**Example of current slow pattern:**
-
-```typescript
-test.beforeEach(async ({ page }) => {
-  await setupSuperuserMocks(page);
-  await loginViaUI(page); // ← 5-7s UI login EVERY test
-  await page.goto('/admin');
-});
-```
-
-**Solution: Playwright Storage State** (SAVE ~600-700s)
-
-```typescript
-// auth.setup.ts - Run ONCE per worker
-import { test as setup } from '@playwright/test';
-
-setup('authenticate as admin', async ({ page }) => {
-  await setupSuperuserMocks(page);
-  await loginViaUI(page);
-  await page.context().storageState({ path: 'e2e/.auth/admin.json' });
-});
-
-setup('authenticate as regular user', async ({ page }) => {
-  await setupAuthenticatedMocks(page);
-  await loginViaUI(page);
-  await page.context().storageState({ path: 'e2e/.auth/user.json' });
-});
-```
-
-```typescript
-// playwright.config.ts
-export default defineConfig({
-  projects: [
-    { name: 'setup', testMatch: /.*\.setup\.ts/ },
-    {
-      name: 'admin tests',
-      use: { storageState: 'e2e/.auth/admin.json' },
-      dependencies: ['setup'],
-      testMatch: /admin-.*\.spec\.ts/,
-    },
-    {
-      name: 'user tests',
-      use: { storageState: 'e2e/.auth/user.json' },
-      dependencies: ['setup'],
-      testMatch: /settings-.*\.spec\.ts/,
-    },
-  ],
-});
-```
-
-```typescript
-// admin-users.spec.ts - NO MORE loginViaUI!
-test.beforeEach(async ({ page }) => {
-  // Auth already loaded from storageState
-  await page.goto('/admin/users'); // ← Direct navigation, ~1-2s
-});
-```
-
-**Expected Improvement**: 5-6s → 0.5-1s per test = **~600s saved** (133 tests × 5s)
-
----
-
-### 2. Redundant Navigation Tests (MEDIUM IMPACT)
-
-**Problem**: Separate tests for "navigate to X" and "display X page"
-
-- **Impact**: 3-5s per redundant test × ~15 tests = ~60s wasted
-
-**Current slow pattern:**
-
-```typescript
-test('should navigate to users page', async ({ page }) => {
-  await page.goto('/admin/users'); // 3s
-  await expect(page).toHaveURL('/admin/users');
-  await expect(page.locator('h1')).toContainText('User Management');
-});
-
-test('should display user management page', async ({ page }) => {
-  await page.goto('/admin/users'); // 3s DUPLICATE
-  await expect(page.locator('h1')).toContainText('User Management');
-  await expect(page.getByText(/manage users/i)).toBeVisible();
-});
-```
-
-**Optimized pattern:**
-
-```typescript
-test('should navigate to users page and display content', async ({ page }) => {
-  await page.goto('/admin/users'); // 3s ONCE
-
-  // Navigation assertions
-  await expect(page).toHaveURL('/admin/users');
-
-  // Content assertions
-  await expect(page.locator('h1')).toContainText('User Management');
-  await expect(page.getByText(/manage users/i)).toBeVisible();
-  await expect(page.getByRole('button', { name: 'Create User' })).toBeVisible();
-});
-```
-
-**Expected Improvement**: **~45-60s saved** (15 tests eliminated)
-
----
-
-### 3. Flaky Test Fix (CRITICAL)
-
-**Problem**: Test #218 failed once, passed on retry
-
-```
-Test: settings-password.spec.ts:24:7 › Password Change › should display password change form
-Failed: 12.8s → Retry passed: 8.3s
-```
-
-**Root Cause Options**:
-
-1. Race condition in form rendering
-2. Slow network request not properly awaited
-3. Animation/transition timing issue
-
-**Investigation needed:**
-
-```typescript
-// Current test (lines 24-35)
-test('should display password change form', async ({ page }) => {
-  await page.goto('/settings/password');
-
-  // ← Likely missing waitForLoadState or explicit wait
-  await expect(page.getByLabel(/current password/i)).toBeVisible();
-  await expect(page.getByLabel(/new password/i)).toBeVisible();
-  await expect(page.getByLabel(/confirm password/i)).toBeVisible();
-});
-```
-
-**Temporary Solution: Skip until fixed**
-
-```typescript
-test.skip('should display password change form', async ({ page }) => {
-  // TODO: Fix race condition (issue #XXX)
-  await page.goto('/settings/password');
-  await page.waitForLoadState('networkidle'); // ← Add this
-  await expect(page.getByLabel(/current password/i)).toBeVisible();
-});
-```
-
-**Expected Improvement**: Eliminate retry overhead + improve reliability
-
----
-
-### 4. Optimize Wait Timeouts (LOW IMPACT)
-
-**Problem**: Default timeout is 10s for all assertions
-
-- **Impact**: Tests wait unnecessarily when elements load faster
-
-**Current global timeout:**
-
-```typescript
-// playwright.config.ts
-export default defineConfig({
-  timeout: 30000, // Per test
-  expect: { timeout: 10000 }, // Per assertion
-});
-```
-
-**Optimized for fast-loading pages:**
-
-```typescript
-export default defineConfig({
-  timeout: 20000, // Reduce from 30s
-  expect: { timeout: 5000 }, // Reduce from 10s (most elements load <2s)
-});
-```
-
-**Expected Improvement**: **~100-150s saved** (faster failures, less waiting)
-
----
-
-## Implementation Priority
-
-### Phase 1: Quick Wins (1-2 hours work)
-
-1. ✅ **Skip flaky test #218** temporarily
-2. ✅ **Reduce timeout defaults** (5s for expects, 20s for tests)
-3. ✅ **Combine 5 most obvious redundant navigation tests**
-
-**Expected savings**: ~100-150s (5-7% improvement)
-
----
-
-### Phase 2: Auth State Caching (2-4 hours work)
-
-1. ✅ Create `e2e/auth.setup.ts` with storage state setup
-2. ✅ Update `playwright.config.ts` with projects + dependencies
-3. ✅ Remove `loginViaUI` from all admin test `beforeEach` hooks
-4. ✅ Update auth helper to support both mock + storageState modes
-
-**Expected savings**: ~600-700s (30-35% improvement)
-
----
-
-### Phase 3: Deep Optimization (4-8 hours work)
-
-1. ✅ Investigate and fix flaky test root cause
-2. ✅ Audit all navigation tests for redundancy
-3. ✅ Combine related assertions (e.g., all stat cards in one test)
-4. ✅ Profile slowest 10 tests individually
-
-**Expected savings**: ~150-200s (7-10% improvement)
-
----
-
-## Total Expected Improvement
-
-| Phase     | Time Investment | Time Saved | % Improvement |
-| --------- | --------------- | ---------- | ------------- |
-| Phase 1   | 1-2 hours       | ~150s      | 7%            |
-| Phase 2   | 2-4 hours       | ~700s      | 35%           |
-| Phase 3   | 4-8 hours       | ~200s      | 10%           |
-| **Total** | **7-14 hours**  | **~1050s** | **50-60%**    |
-
-**Final target**: 2100s → 1050s = **~17-18 minutes** (currently ~35 minutes)
-
----
-
-## Risks and Considerations
-
-### Storage State Caching Risks:
-
-1. **Test isolation**: Shared auth state could cause cross-test pollution
-   - **Mitigation**: Use separate storage files per role, clear cookies between tests
-2. **Stale auth tokens**: Mock tokens might expire
-   - **Mitigation**: Use long-lived test tokens (24h expiry)
-3. **Debugging difficulty**: Harder to debug auth issues
-   - **Mitigation**: Keep `loginViaUI` tests for auth flow verification
-
-### Recommended Safeguards:
-
-```typescript
-// Clear non-auth state between tests
-test.beforeEach(async ({ page }) => {
-  await page.goto('/admin');
-  await page.evaluate(() => {
-    // Clear localStorage except auth tokens
-    const tokens = {
-      access_token: localStorage.getItem('access_token'),
-      refresh_token: localStorage.getItem('refresh_token'),
-    };
-    localStorage.clear();
-    if (tokens.access_token) localStorage.setItem('access_token', tokens.access_token);
-    if (tokens.refresh_token) localStorage.setItem('refresh_token', tokens.refresh_token);
-  });
-});
-```
