+
+## TASK-006: Backend Bugfixes Applied
+
+### Bugfix 1: Report ID Generation Error
+**File**: `src/api/v1/reports.py`  
+**Issue**: Report ID generation using `UUID(int=datetime.now().timestamp())` caused TypeError because timestamp returns a float, not int.  
+**Fix**: Changed to use `uuid4()` for proper UUID generation.
+
+```python
+# Before:
+report_id = UUID(int=datetime.now().timestamp())
+
+# After:
+report_id = uuid4()
+```
+
+### Bugfix 2: Database Column Mismatch - Reports Table
+**Files**: 
+- `alembic/versions/e80c6eef58b2_create_reports_table.py`
+- `src/models/report.py`
+
+**Issue**: Migration used `metadata` column but model expected `extra_data`. Also missing `created_at` and `updated_at` columns from TimestampMixin.  
+**Fix**: 
+1. Changed migration to use `extra_data` column name
+2. Added `created_at` and `updated_at` columns to migration
+
+### Bugfix 3: Database Column Mismatch - Scenario Metrics Table
+**File**: `alembic/versions/5e247ed57b77_create_scenario_metrics_table.py`  
+**Issue**: Migration used `metadata` column but model expected `extra_data`.  
+**Fix**: Changed migration to use `extra_data` column name.
+
+### Bugfix 4: Report Sections Default Value Error
+**File**: `src/schemas/report.py`  
+**Issue**: Default value for `sections` field was a list of strings instead of ReportSection enum values, causing AttributeError when accessing `.value`.  
+**Fix**: Changed default to use enum values.
+
+```python
+# Before:
+sections: List[ReportSection] = Field(
+    default=["summary", "costs", "metrics", "logs", "pii"],
+    ...
+)
+
+# After:
+sections: List[ReportSection] = Field(
+    default=[ReportSection.SUMMARY, ReportSection.COSTS, ReportSection.METRICS, ReportSection.LOGS, ReportSection.PII],
+    ...
+)
+```
+
+### Bugfix 5: Database Configuration
+**Files**:
+- `src/core/database.py`
+- `alembic.ini`
+- `.env`
+
+**Issue**: Database URL was using incorrect credentials (`app/changeme` instead of `postgres/postgres`).  
+**Fix**: Updated default database URLs to match Docker container credentials.
+
+### Bugfix 6: API Version Update
+**File**: `src/main.py`  
+**Issue**: API version was still showing 0.2.0 instead of 0.4.0.  
+**Fix**: Updated version string to "0.4.0".
+
+---
+
+## TASK-007: API Documentation Verification
+
+### OpenAPI Schema Status: ✅ Complete
+
+**API Information:**
+- Title: mockupAWS

+## How to Run Tests
+
+### Local Development
+
+```bash
+# Install dependencies
+cd frontend
+npm install
+
+# Install Playwright browsers
+npx playwright install
+
+# Run all tests
+npm run test:e2e
+
+# Run with UI mode (interactive)
+npm run test:e2e:ui
+
+# Run specific test file
+npx playwright test scenario-crud.spec.ts
+
+# Run in debug mode
+npm run test:e2e:debug
+
+# Run with visible browser
+npm run test:e2e:headed
+```
+
+### CI Mode
+
+```bash
+# Run tests as in CI
+npm run test:e2e:ci
+```
+
+### Visual Regression
+
+```bash
+# Run visual tests
+npx playwright test visual-regression.spec.ts
+
+# Update baseline screenshots
+UPDATE_BASELINE=true npx playwright test visual-regression.spec.ts
+```
+
+## Prerequisites
+
+1. **Backend running** on http://localhost:8000
+2. **Frontend dev server** will be started automatically by Playwright
+3. **PostgreSQL** database (if using full backend)
+
+## Coverage Report Strategy
+
+### Current Setup
+- HTML reporter generates `e2e-report/` directory
+- JUnit XML output for CI integration
+- Screenshots and videos on failure
+- Trace files for debugging
+
+### Future Enhancements
+To add code coverage:
+
+1. **Frontend Coverage**:
+   ```bash
+   npm install -D @playwright/test istanbul-lib-coverage nyc
+   ```
+   Instrument code with Istanbul and collect coverage during tests.
+
+2. **Backend Coverage**:
+   Use pytest-cov with Playwright tests to measure API coverage.
+
+3. **Coverage Reporting**:
+   - Upload coverage reports to codecov.io
+   - Block PRs if coverage drops below threshold
+   - Generate coverage badges
+
+## GitHub Actions Workflow
+
+The workflow (`/.github/workflows/e2e.yml`) includes:
+
+1. **E2E Tests Job**: Runs all tests on every push/PR
+2. **Visual Regression Job**: Compares screenshots on PRs
+3. **Smoke Tests Job**: Quick sanity checks on pushes
+
+### Workflow Features
+- PostgreSQL service container
+- Backend server startup
+- Artifact upload for reports
+- Parallel job execution
+- Conditional visual regression on PRs
+
+## Test Architecture
+
+### Design Principles
+1. **Deterministic**: Tests use unique names and clean up after themselves
+2. **Isolated**: Each test creates its own data
+3. **Fast**: Parallel execution where possible
+4. **Reliable**: Retry logic for flaky operations
+5. **Maintainable**: Shared utilities and fixtures
+
+### Data Flow
+```
+Global Setup → Test Suite → Individual Tests → Global Teardown
+    ↓              ↓              ↓                ↓
+  Create dirs  Create data   Run assertions   Cleanup data
+```
+
+### API Helpers
+All test files use shared API helpers for:
+- Creating/deleting scenarios
+- Starting/stopping scenarios
+- Sending logs
+- Generating unique names
+
+## Next Steps
+
+1. **Run setup verification**:
+   ```bash
+   npx playwright test setup-verification.spec.ts
+   ```
+
+2. **Generate baseline screenshots** (for visual regression):
+   ```bash
+   UPDATE_BASELINE=true npx playwright test visual-regression.spec.ts
+   ```
+
+3. **Add data-testid attributes** to frontend components for more robust selectors
+
+4. **Configure environment variables** in `.env` file if needed
+
+5. **Start backend** and run full test suite:
+   ```bash
+   npm run test:e2e
+   ```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Browsers not installed**:
+   ```bash
+   npx playwright install
+   ```
+
+2. **Backend not accessible**:
+   - Ensure backend is running on port 8000
+   - Check CORS configuration
+
+3. **Tests timeout**:
+   - Increase timeout in `playwright.config.ts`
+   - Check if dev server starts correctly
+
+4. **Visual regression failures**:
+   - Review diff images in `e2e/screenshots/diff/`
+   - Update baselines if UI intentionally changed
+

 ## Principi di Design
 
 ### 🔐 Safety First
@@ -263,30 +480,126 @@ npm run lint
 npm run build
 ```
 
+## Configurazione Sicurezza (v0.5.0)
+
+### Setup Iniziale JWT
+
+1. **Genera JWT Secret:**
+   ```bash
+   openssl rand -hex 32
+   ```
+
+2. **Configura .env:**
+   ```env
+   JWT_SECRET_KEY=<generated-secret>
+   JWT_ALGORITHM=HS256
+   ACCESS_TOKEN_EXPIRE_MINUTES=30
+   REFRESH_TOKEN_EXPIRE_DAYS=7
+   BCRYPT_ROUNDS=12
+   ```
+
+3. **Verifica sicurezza:**
+   ```bash
+   # Controlla che JWT_SECRET_KEY sia >= 32 caratteri
+   echo $JWT_SECRET_KEY | wc -c
+   # Deve mostrare 65+ (64 hex chars + newline)
+   ```
+
+### Rate Limiting
+
+I limiti sono configurati automaticamente:
+
+| Endpoint | Limite | Finestra |
+|----------|--------|----------|
+| `/auth/*` | 5 req | 1 minuto |
+| `/api-keys/*` | 10 req | 1 minuto |
+| `/reports/*` | 10 req | 1 minuto |
+| API generale | 100 req | 1 minuto |
+| `/ingest` | 1000 req | 1 minuto |
+
+### HTTPS in Produzione
+
+Per produzione, configura HTTPS obbligatorio:
+
+```nginx
+server {
+    listen 443 ssl http2;
+    server_name api.mockupaws.com;
+    
+    ssl_certificate /path/to/cert.pem;
+    ssl_certificate_key /path/to/key.pem;
+    ssl_protocols TLSv1.3;
+    
+    # HSTS
+    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
+    
+    location / {
+        proxy_pass http://backend:8000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+
+# Redirect HTTP to HTTPS
+server {
+    listen 80;
+    server_name api.mockupaws.com;
+    return 301 https://$server_name$request_uri;

+## Authentication Architecture
+
+### JWT Token Implementation
+
+#### Token Configuration
+
+| Parameter | Value | Description |
+|-----------|-------|-------------|
+| **Algorithm** | HS256 | HMAC with SHA-256 |
+| **Secret Length** | ≥32 characters | Minimum 256 bits |
+| **Access Token TTL** | 30 minutes | Short-lived for security |
+| **Refresh Token TTL** | 7 days | Longer-lived for UX |
+| **Token Rotation** | Enabled | New refresh token on each use |
+
+#### Token Structure
+
+```json
+{
+  "sub": "user-uuid",
+  "exp": 1712592000,
+  "iat": 1712590200,
+  "type": "access",
+  "jti": "unique-token-id"
+}
+```
+
+#### Security Requirements
+
+1. **JWT Secret Generation:**
+   ```bash
+   # Generate a secure 256-bit secret
+   openssl rand -hex 32
+   
+   # Store in .env file
+   JWT_SECRET_KEY=your-generated-secret-here-32chars-min
+   ```
+
+2. **Secret Storage:**
+   - Never commit secrets to version control
+   - Use environment variables or secret management
+   - Rotate secrets periodically (recommended: 90 days)
+   - Use different secrets per environment
+
+3. **Token Validation:**
+   - Verify signature integrity
+   - Check expiration time
+   - Validate `sub` (user ID) exists
+   - Reject tokens with `type: refresh` for protected routes
+
+### Password Security
+
+#### bcrypt Configuration
+
+| Parameter | Value | Description |
+|-----------|-------|-------------|
+| **Algorithm** | bcrypt | Industry standard |
+| **Cost Factor** | 12 | ~250ms per hash |
+| **Salt Size** | 16 bytes | Random per password |
+
+#### Password Requirements
+
+- Minimum 8 characters
+- At least one uppercase letter
+- At least one lowercase letter
+- At least one number
+- At least one special character (!@#$%^&*)
+
+#### Password Storage
+
+```python
+# NEVER store plaintext passwords
+# ALWAYS hash before storage
+import bcrypt
+
+password_hash = bcrypt.hashpw(
+    password.encode('utf-8'), 
+    bcrypt.gensalt(rounds=12)
+)
+```
+
+---
+
+## API Keys Security
+
+### Key Generation
+
+```
+Format: mk_<prefix>_<random>
+Example: mk_a3f9b2c1_xK9mP2nQ8rS4tU7vW1yZ
+         │  │         │
+         │  │         └── 32 random chars (base64url)
+         │  └── 8 char prefix (identification)
+         └── Fixed prefix (mk_)
+```
+
+### Storage Security
+
+| Aspect | Implementation | Status |
+|--------|---------------|--------|
+| **Storage** | Hash only (SHA-256) | ✅ Implemented |
+| **Transmission** | HTTPS only | ✅ Required |
+| **Prefix** | First 8 chars stored plaintext | ✅ Implemented |
+| **Lookup** | By prefix + hash comparison | ✅ Implemented |
+
+**⚠️ CRITICAL:** The full API key is only shown once at creation. Store it securely!
+
+### Scopes and Permissions
+
+Available scopes:
+
+| Scope | Description | Access Level |
+|-------|-------------|--------------|
+| `read:scenarios` | Read scenarios | Read-only |
+| `write:scenarios` | Create/update scenarios | Write |
+| `delete:scenarios` | Delete scenarios | Delete |
+| `read:reports` | Read/download reports | Read-only |
+| `write:reports` | Generate reports | Write |
+| `read:metrics` | View metrics | Read-only |
+| `ingest:logs` | Send logs to scenarios | Special |
+
+### API Key Validation Flow
+
+```

+## Rate Limiting
+
+### Endpoint Limits
+
+| Endpoint Category | Limit | Window | Burst |
+|-------------------|-------|--------|-------|
+| **Authentication** (`/auth/*`) | 5 requests | 1 minute | No |
+| **API Key Management** (`/api-keys/*`) | 10 requests | 1 minute | No |
+| **Report Generation** (`/reports/*`) | 10 requests | 1 minute | No |
+| **General API** | 100 requests | 1 minute | 20 |
+| **Ingest** (`/ingest`) | 1000 requests | 1 minute | 100 |
+
+### Rate Limit Headers
+
+```http
+HTTP/1.1 200 OK
+X-RateLimit-Limit: 100
+X-RateLimit-Remaining: 95
+X-RateLimit-Reset: 1712590260
+```
+
+### Rate Limit Response
+
+```http
+HTTP/1.1 429 Too Many Requests
+Content-Type: application/json
+Retry-After: 60
+
+{
+  "error": "rate_limited",
+  "message": "Rate limit exceeded. Try again in 60 seconds.",
+  "retry_after": 60
+}
+```
+
+---
+
+## CORS Configuration
+
+### Allowed Origins
+
+```python
+# Development
+allowed_origins = [
+    "http://localhost:5173",    # Vite dev server
+    "http://localhost:3000",    # Alternative dev port
+]
+
+# Production (configure as needed)
+allowed_origins = [
+    "https://app.mockupaws.com",
+    "https://api.mockupaws.com",
+]
+```
+
+### CORS Policy
+
+| Setting | Value | Description |
+|---------|-------|-------------|
+| `allow_credentials` | `true` | Allow cookies/auth headers |
+| `allow_methods` | `["GET", "POST", "PUT", "DELETE"]` | HTTP methods |
+| `allow_headers` | `["*"]` | All headers allowed |
+| `max_age` | `600` | Preflight cache (10 min) |
+
+### Security Headers
+
+```http
+Strict-Transport-Security: max-age=31536000; includeSubDomains
+X-Content-Type-Options: nosniff
+X-Frame-Options: DENY
+X-XSS-Protection: 1; mode=block
+Content-Security-Policy: default-src 'self'
+```
+
+---
+
+## Input Validation
+
+### SQL Injection Prevention
+
+- ✅ **Parameterized Queries:** SQLAlchemy ORM with bound parameters
+- ✅ **No Raw SQL:** All queries through ORM
+- ✅ **Input Sanitization:** Pydantic validation before DB operations
+
+```python
+# ✅ SAFE - Uses parameterized queries
+result = await db.execute(
+    select(Scenario).where(Scenario.id == scenario_id)
+)
+
+# ❌ NEVER DO THIS - Vulnerable to SQL injection
+query = f"SELECT * FROM scenarios WHERE id = '{scenario_id}'"
+```
+
+### XSS Prevention
+
+- ✅ **Output Encoding:** All user data HTML-escaped in responses
+- ✅ **Content-Type Headers:** Proper headers prevent MIME sniffing
+- ✅ **CSP Headers:** Content Security Policy restricts script sources
+
+### PII Detection
+
+Built-in PII detection in log ingestion:
+
+```python
+pii_patterns = {
+    'email': r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b',
+    'ssn': r'\b\d{3}-\d{2}-\d{4}\b',
+    'credit_card': r'\b(?:\d[ -]*?){13,16}\b',
+    'phone': r'\b\d{3}[-.]?\d{3}[-.]?\d{4}\b'
+}
+```
+
+---
+
+## Data Protection
+
+### Data Classification
+
+| Data Type | Classification | Storage | Encryption |
+|-----------|---------------|---------|------------|
+| Passwords | Critical | bcrypt hash | N/A (one-way) |
+| API Keys | Critical | SHA-256 hash | N/A (one-way) |
+| JWT Secrets | Critical | Environment | At rest |
+| User Emails | Sensitive | Database | TLS transit |
+| Scenario Data | Internal | Database | TLS transit |
+| Logs | Internal | Database | TLS transit |
+
+### Encryption in Transit
+
+- **TLS 1.3** required for all communications
+- **HSTS** enabled with 1-year max-age
+- **Certificate pinning** recommended for mobile clients
+
+### Encryption at Rest
+
+- Database-level encryption (PostgreSQL TDE)
+- Encrypted backups
+- Encrypted environment files
+
+---
+
+## Security Best Practices
+
+### For Administrators
+
+1. **Environment Setup:**
+   ```bash
+   # Generate strong secrets
+   export JWT_SECRET_KEY=$(openssl rand -hex 32)
+   export POSTGRES_PASSWORD=$(openssl rand -base64 32)
+   ```
+
+2. **HTTPS Enforcement:**
+   - Never run production without HTTPS
+   - Use Let's Encrypt or commercial certificates
+   - Redirect HTTP to HTTPS
+
+3. **Secret Rotation:**
+   - Rotate JWT secrets every 90 days
+   - Rotate database credentials every 180 days
+   - Revoke and regenerate API keys annually
+
+4. **Monitoring:**
+   - Log all authentication failures
+   - Monitor rate limit violations
+   - Alert on suspicious patterns
+
+### For Developers
+
+1. **Never Log Secrets:**
+   ```python
+   # ❌ NEVER DO THIS
+   logger.info(f"User login with password: {password}")
+   
+   # ✅ CORRECT
+   logger.info(f"User login attempt: {user_email}")
+   ```
+
+2. **Validate All Input:**
+   - Use Pydantic models for request validation
+   - Sanitize user input before display
+   - Validate file uploads (type, size)
+
+3. **Secure Dependencies:**
+   ```bash
+   # Regularly audit dependencies
+   pip-audit
+   safety check
+   ```
+
+### For Users
+
+1. **Password Guidelines:**
+   - Use unique passwords per service
+   - Enable 2FA when available
+   - Never share API keys
+
+2. **API Key Management:**
+   - Store keys in environment variables
+   - Never commit keys to version control
+   - Rotate keys periodically
+

+# MockupAWS v0.5.0 Infrastructure Setup Guide
+
+This document provides setup instructions for the infrastructure components introduced in v0.5.0.
+
+## Table of Contents
+
+1. [Secrets Management](#secrets-management)
+2. [Email Configuration](#email-configuration)
+3. [Cron Job Deployment](#cron-job-deployment)
+
+---
+
+## Secrets Management
+
+### Quick Start
+
+Generate secure secrets automatically:
+
+```bash
+# Make the script executable
+chmod +x scripts/setup-secrets.sh
+
+# Run the setup script
+./scripts/setup-secrets.sh
+
+# Or specify a custom output file
+./scripts/setup-secrets.sh /path/to/.env.production
+```
+
+### Manual Secret Generation
+
+If you prefer to generate secrets manually:
+
+```bash
+# Generate JWT Secret (256 bits)
+openssl rand -hex 32
+
+# Generate API Key Encryption Key
+openssl rand -hex 16
+
+# Generate secure random password
+date +%s | sha256sum | base64 | head -c 32 ; echo
+```
+
+### Required Secrets
+
+| Variable | Purpose | Generation |
+|----------|---------|------------|
+| `JWT_SECRET_KEY` | Sign JWT tokens | `openssl rand -hex 32` |
+| `DATABASE_URL` | PostgreSQL connection | Update password manually |
+| `SENDGRID_API_KEY` | Email delivery | From SendGrid dashboard |
+| `AWS_ACCESS_KEY_ID` | AWS SES (optional) | From AWS IAM |
+| `AWS_SECRET_ACCESS_KEY` | AWS SES (optional) | From AWS IAM |
+
+### Security Best Practices
+
+1. **Never commit `.env` files to git**
+   ```bash
+   # Ensure .env is in .gitignore
+   echo ".env" >> .gitignore
+   ```
+
+2. **Use different secrets for each environment**
+   - Development: `.env`
+   - Staging: `.env.staging`
+   - Production: Use secrets manager (AWS Secrets Manager, HashiCorp Vault)
+
+3. **Rotate secrets regularly**
+   - JWT secrets: Every 90 days
+   - API keys: Every 30 days
+   - Database passwords: Every 90 days
+
+4. **Production Recommendations**
+   - Use AWS Secrets Manager or HashiCorp Vault
+   - Enable encryption at rest
+   - Use IAM roles instead of hardcoded AWS credentials when possible
+
+---
+
+## Email Configuration
+
+### Option 1: SendGrid (Recommended for v0.5.0)
+
+**Free Tier**: 100 emails/day
+
+#### Setup Steps
+
+1. **Create SendGrid Account**
+   ```
+   https://signup.sendgrid.com/
+   ```
+
+2. **Generate API Key**
+   - Go to: https://app.sendgrid.com/settings/api_keys
+   - Click "Create API Key"
+   - Name: `mockupAWS-production`
+   - Permissions: **Full Access** (or restrict to "Mail Send")
+   - Copy the key (starts with `SG.`)
+
+3. **Verify Sender Domain**
+   - Go to: https://app.sendgrid.com/settings/sender_auth
+   - Choose "Domain Authentication"
+   - Follow DNS configuration steps
+   - Wait for verification (usually instant, up to 24 hours)
+
+4. **Configure Environment Variables**
+   ```bash
+   EMAIL_PROVIDER=sendgrid
+   SENDGRID_API_KEY=SG.your_actual_api_key_here
+   EMAIL_FROM=noreply@yourdomain.com
+   ```
+
+#### Testing SendGrid
+
+```bash
+# Run the email test script (to be created by backend team)
+python -m src.scripts.test_email --to your@email.com
+```
+
+### Option 2: AWS SES (Amazon Simple Email Service)
+
+**Free Tier**: 62,000 emails/month (when sending from EC2)
+
+#### Setup Steps
+
+1. **Configure SES in AWS Console**
+   ```
+   https://console.aws.amazon.com/ses/
+   ```
+
+2. **Verify Email or Domain**
+   - For testing: Verify individual email address
+   - For production: Verify entire domain
+
+3. **Get AWS Credentials**
+   - Create IAM user with `ses:SendEmail` and `ses:SendRawEmail` permissions
+   - Generate Access Key ID and Secret Access Key
+
+4. **Move Out of Sandbox** (required for production)
+   - Open a support case to increase sending limits
+   - Provide use case and estimated volume
+
+5. **Configure Environment Variables**
+   ```bash
+   EMAIL_PROVIDER=ses
+   AWS_ACCESS_KEY_ID=AKIA...
+   AWS_SECRET_ACCESS_KEY=...
+   AWS_REGION=us-east-1
+   EMAIL_FROM=noreply@yourdomain.com
+   ```
+
+### Email Testing Guide
+
+#### Development Testing
+
+```bash
+# 1. Start the backend
+uv run uvicorn src.main:app --reload
+
+# 2. Send test email via API
+curl -X POST http://localhost:8000/api/v1/test/email \
+  -H "Content-Type: application/json" \
+  -d '{"to": "your@email.com", "subject": "Test", "body": "Hello"}'
+```
+
+#### Email Templates
+
+The following email templates are available in v0.5.0:
+
+| Template | Trigger | Variables |
+|----------|---------|-----------|
+| `welcome` | User registration | `{{name}}`, `{{login_url}}` |
+| `report_ready` | Report generation complete | `{{report_name}}`, `{{download_url}}` |
+| `scheduled_report` | Scheduled report delivery | `{{scenario_name}}`, `{{attachment}}` |
+| `password_reset` | Password reset request | `{{reset_url}}`, `{{expires_in}}` |
+
+---
+
+## Cron Job Deployment
+
+### Overview
+
+Three deployment options are available for report scheduling:
+
+| Option | Pros | Cons | Best For |
+|--------|------|------|----------|
+| **1. APScheduler (in-process)** | Simple, no extra services | Runs in API container | Small deployments |
+| **2. APScheduler (standalone)** | Separate scaling, resilient | Requires extra container | Medium deployments |
+| **3. Celery + Redis** | Distributed, scalable, robust | More complex setup | Large deployments |
+
+### Option 1: APScheduler In-Process (Simplest)
+
+No additional configuration needed. The scheduler runs within the main backend process.
+
+**Pros:**
+- Zero additional setup
+- Works immediately
+
+**Cons:**
+- API restarts interrupt scheduled jobs
+- Cannot scale independently
+
+**Enable:**
+```bash
+SCHEDULER_ENABLED=true
+SCHEDULER_INTERVAL_MINUTES=5
+```
+
+### Option 2: Standalone Scheduler Service (Recommended for v0.5.0)
+
+Runs the scheduler in a separate Docker container.
+
+**Deployment:**
+```bash
+# Start with main services
+docker-compose -f docker-compose.yml -f docker-compose.scheduler.yml up -d
+
+# View logs
+docker-compose -f docker-compose.scheduler.yml logs -f scheduler
+```
+
+**Pros:**
+- Independent scaling
+- Resilient to API restarts
+- Clear separation of concerns
+
+**Cons:**
+- Requires additional container
+
+### Option 3: Celery + Redis (Production-Scale)
+
+For high-volume or mission-critical scheduling.
+
+**Prerequisites:**
+```bash
+# Add to requirements.txt
+celery[redis]>=5.0.0
+redis>=4.0.0
+```
+
+**Deployment:**
+```bash
+# Uncomment celery services in docker-compose.scheduler.yml
+docker-compose -f docker-compose.yml -f docker-compose.scheduler.yml up -d
+
+# Scale workers if needed
+docker-compose -f docker-compose.scheduler.yml up -d --scale celery-worker=3
+```
+
+### Scheduler Configuration
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `SCHEDULER_ENABLED` | `true` | Enable/disable scheduler |
+| `SCHEDULER_INTERVAL_MINUTES` | `5` | Check interval for due jobs |
+| `REDIS_URL` | `redis://localhost:6379/0` | Redis connection (Celery) |
+
+### Monitoring Scheduled Jobs
+
+```bash
+# View scheduler logs
+docker-compose logs -f scheduler
+
+# Check Redis queue (if using Celery)
+docker-compose exec redis redis-cli llen celery
+
+# Monitor Celery workers
+docker-compose exec celery-worker celery -A src.jobs.celery_app inspect active
+```
+
+### Production Deployment Checklist
+
+- [ ] Secrets generated and secured
+- [ ] Email provider configured and tested
+- [ ] Database migrations applied
+- [ ] Redis running (if using Celery)
+- [ ] Scheduler container started
+- [ ] Logs being collected
+- [ ] Health checks configured
+- [ ] Monitoring alerts set up
+
+---
+
+## Troubleshooting
+
+### Email Not Sending
+
+```bash
+# Check email configuration
+echo $EMAIL_PROVIDER
+echo $SENDGRID_API_KEY
+
+# Test SendGrid API directly
+curl -X POST https://api.sendgrid.com/v3/mail/send \
+  -H "Authorization: Bearer $SENDGRID_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"personalizations":[{"to":[{"email":"test@example.com"}]}],"from":{"email":"noreply@mockupaws.com"},"subject":"Test","content":[{"type":"text/plain","value":"Hello"}]}'
+```
+
+### Scheduler Not Running
+
+```bash
+# Check if scheduler container is running
+docker-compose ps
+
+# View scheduler logs
+docker-compose logs scheduler
+
+# Restart scheduler
+docker-compose restart scheduler
+```
+
+### JWT Errors
+
+```bash
+# Verify JWT secret length (should be 32+ chars)
+echo -n $JWT_SECRET_KEY | wc -c
+
+# Regenerate if needed
+openssl rand -hex 32
+```

+}
+```
+
+---
+
+### 🛡️ Rate Limiting Verification
+
+#### Test Commands
+
+```bash
+# Test auth rate limiting (should block after 5 requests)

+         -H "Content-Type: application/json" \
+         -d '{"email":"test@test.com","password":"wrong"}' \
+         -w "Status: %{http_code}\n" -o /dev/null -s
+done
+# Expected: First 5 = 401, 6th+ = 429
+
+# Test general rate limiting (should block after 100 requests)
+for i in {1..105}; do
+    curl http://localhost:8000/health \
+         -w "Status: %{http_code}\n" -o /dev/null -s
+done
+# Expected: First 100 = 200, 101st+ = 429
+```
+
+#### Checklist
+
+- [ ] Auth endpoints return 429 after 5 failed attempts
+- [ ] Rate limit headers are present in responses
+- [ ] Rate limits reset after time window
+- [ ] Different limits for different endpoint types
+- [ ] Burst allowance for legitimate traffic
+
+---
+
+### 🔑 JWT Security Verification
+
+#### Secret Generation
+
+```bash
+# Generate a secure JWT secret
+openssl rand -hex 32
+
+# Example output:
+# a3f5c8e9d2b1f4a7c6e8d9b0a2c4e6f8a1b3d5c7e9f2a4b6c8d0e2f4a6b8c0d
+
+# Verify length (should be 64 hex chars = 32 bytes)
+openssl rand -hex 32 | wc -c
+# Expected: 65 (64 chars + newline)
+```
+
+#### Token Validation Tests
+
+```bash
+# 1. Test valid token
+curl http://localhost:8000/api/v1/auth/me \
+     -H "Authorization: Bearer <valid_token>"
+# Expected: 200 with user data
+
+# 2. Test expired token
+curl http://localhost:8000/api/v1/auth/me \
+     -H "Authorization: Bearer <expired_token>"
+# Expected: 401 {"error": "token_expired"}
+
+# 3. Test invalid signature
+curl http://localhost:8000/api/v1/auth/me \
+     -H "Authorization: Bearer invalid.token.here"
+# Expected: 401 {"error": "invalid_token"}
+
+# 4. Test missing token
+curl http://localhost:8000/api/v1/auth/me
+# Expected: 401 {"error": "missing_token"}
+```
+
+#### Checklist
+
+- [ ] JWT secret is ≥32 characters
+- [ ] Access tokens expire in 30 minutes
+- [ ] Refresh tokens expire in 7 days
+- [ ] Token rotation is implemented
+- [ ] Expired tokens are rejected
+- [ ] Invalid signatures are rejected
+- [ ] Token payload doesn't contain sensitive data
+
+---
+
+### 🗝️ API Keys Validation
+
+#### Creation Flow Test
+
+```bash
+# 1. Create API key
+curl -X POST http://localhost:8000/api/v1/api-keys \
+     -H "Authorization: Bearer <jwt_token>" \
+     -H "Content-Type: application/json" \
+     -d '{
+         "name": "Test Key",
+         "scopes": ["read:scenarios"],
+         "expires_days": 30
+     }'
+# Response should include: {"key": "mk_xxxx...", ...}
+# ⚠️ Save this key - it won't be shown again!
+
+# 2. List API keys (should NOT show full key)
+curl http://localhost:8000/api/v1/api-keys \
+     -H "Authorization: Bearer <jwt_token>"
+# Response should show: prefix, name, scopes, but NOT full key
+
+# 3. Use API key
+curl http://localhost:8000/api/v1/scenarios \
+     -H "X-API-Key: mk_xxxxxxxx..."
+# Expected: 200 with scenarios list
+
+# 4. Test revoked key
+curl http://localhost:8000/api/v1/scenarios \
+     -H "X-API-Key: <revoked_key>"
+# Expected: 401 {"error": "invalid_api_key"}
+```
+
+#### Storage Verification
+
+```sql
+-- Connect to database
+\c mockupaws
+
+-- Verify API keys are hashed (not plaintext)
+SELECT key_prefix, key_hash, LENGTH(key_hash) as hash_length 
+FROM api_keys 
+LIMIT 5;
+
+-- Expected: key_hash should be 64 chars (SHA-256 hex)
+-- Should NOT see anything like 'mk_' in key_hash column
+```
+
+#### Checklist
+
+- [ ] API keys use `mk_` prefix
+- [ ] Full key shown only at creation
+- [ ] Keys are hashed (SHA-256) in database
+- [ ] Only prefix is stored plaintext
+- [ ] Scopes are validated on each request
+- [ ] Expired keys are rejected
+- [ ] Revoked keys return 401
+- [ ] Keys have associated user_id
+
+---
+
+### 📝 Input Validation Tests
+
+#### SQL Injection Test
+
+```bash
+# Test SQL injection in scenario ID
+curl "http://localhost:8000/api/v1/scenarios/1' OR '1'='1"
+# Expected: 422 (validation error) or 404 (not found)

+## 🚨 Risks & Mitigations
+
+| Rischio | Probabilità | Impatto | Mitigazione | Task Coinvolti |
+|---------|-------------|---------|-------------|----------------|
+| ReportLab complesso | Media | Alto | Usare WeasyPrint (HTML→PDF) | BE-RPT-001, BE-RPT-005 |
+| Performance charts | Media | Medio | Virtualization, data sampling | FE-VIZ-002/003/004 |
+| Dark mode inconsistente | Bassa | Medio | Audit visivo, design tokens | FE-THM-003 |
+| E2E tests flaky | Media | Medio | Retry logic, deterministic selectors | QA-E2E-001/002 |
+| Scope creep | Alta | Medio | Strict deadline, MVP first | Tutti |
+
+---
+
+## 📝 Notes
+
+### Libraries da Installare
+```bash
+# Backend
+pip install reportlab pandas xlsxwriter
+pip install celery redis  # opzionale per background tasks
+
+# Frontend
+npm install recharts date-fns
+npm install @playwright/test
+npm install zustand  # opzionale per theme
+```
+
+### Pattern da Seguire
+- **Report Generation**: Async task con status polling
+- **Charts**: Container/Presentational pattern
+- **Comparison**: Derive state, non duplicare dati
+- **Theme**: CSS variables + Tailwind dark mode
+
+### Performance Considerations
+- Lazy load chart components
+- Debounce resize handlers
+- Virtualize long lists (reports)
+- Cache comparison results
+- Optimize re-renders (React.memo)

+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])

+**Test Environment:** Local development (localhost:5173 / localhost:8000)  
+**Test Scope:** E2E Testing, Manual Feature Testing, Performance Testing, Cross-Browser Testing
+
+---
+
+## EXECUTIVE SUMMARY
+
+### Overall Status: 🔴 NO-GO for Release
+
+**Critical Finding:** The frontend application does not match the expected mockupAWS v0.4.0 implementation. The deployed frontend shows "LogWhispererAI" instead of the mockupAWS dashboard.
+

+| **TOTAL** | **100** | **18** | **61** | **21** | **18%** |
+
+### Failed Tests Analysis
+
+#### 1. Setup Verification Failures (2)
+- **backend API is accessible**: Test expects `/health` endpoint but tries `/api/v1/scenarios` first
+  - Error: Expected 200, received 404
+  - Root Cause: Test logic checks wrong endpoint first
+- **network interception works**: API calls not being intercepted
+  - Error: No API calls intercepted
+  - Root Cause: IPv6 connection refused (::1:8000 vs 127.0.0.1:8000)
+
+#### 2. Navigation Tests Failures (15)
+**Primary Issue:** Frontend UI Mismatch
+- Tests expect: mockupAWS dashboard with "Dashboard", "Scenarios" headings
+- Actual UI: LogWhispererAI landing page (Italian text)
+- **Error Pattern:** `getByRole('heading', { name: 'Dashboard' })` not found
+
+Specific Failures:
+- should navigate to dashboard
+- should navigate to scenarios page
+- should navigate via sidebar links (no sidebar exists)
+- should highlight active navigation item
+- should show 404 page (no 404 page implemented)
+- should maintain navigation state
+- should have working header logo link
+- should have correct page titles (expected "mockupAWS|Dashboard", got "frontend")
+- Mobile navigation tests fail (no hamburger menu)
+- Tablet layout tests fail
+
+#### 3. Scenario CRUD Tests Failures (11)
+**Primary Issue:** API Connection Refused on IPv6
+- Error: `connect ECONNREFUSED ::1:8000`
+- Tests try to create scenarios via API but cannot connect
+- All CRUD operations fail due to connection issues
+
+#### 4. Log Ingestion Tests Failures (9)
+**Primary Issue:** Same as CRUD - API connection refused
+- Cannot create test scenarios
+- Cannot ingest logs
+- Cannot test metrics updates
+
+#### 5. Reports Tests Failures (10)
+**Primary Issue:** API connection refused + UI mismatch
+- Report generation API calls fail
+- Report UI elements not found (tests expect mockupAWS UI)
+
+#### 6. Comparison Tests Failures (7 + 9 skipped)
+**Primary Issue:** API connection + UI mismatch
+- Comparison API endpoint doesn't exist
+- Comparison page UI not implemented
+
+#### 7. Visual Regression Tests Failures (6)
+**Primary Issue:** Baseline screenshots don't match actual UI
+- Baseline: mockupAWS dashboard
+- Actual: LogWhispererAI landing page
+- Tests that pass are checking generic elements (404 page, loading states)

+
+## TASK-002: MANUAL FEATURE TESTING
+
+### Test Results
+
+| Feature | Status | Notes |
+|---------|--------|-------|
+| **Charts: CostBreakdown** | 🔴 FAIL | UI not present - shows LogWhispererAI landing page |
+| **Charts: TimeSeries** | 🔴 FAIL | UI not present |
+| **Dark Mode Toggle** | 🔴 FAIL | Toggle not present in header |
+| **Scenario Comparison** | 🔴 FAIL | Feature not accessible |
+| **Reports: PDF Generation** | 🔴 FAIL | Feature not accessible |
+| **Reports: CSV Generation** | 🔴 FAIL | Feature not accessible |
+| **Reports: Download** | 🔴 FAIL | Feature not accessible |
+
+### Observed UI
+Instead of mockupAWS v0.4.0 features, the frontend displays:
+- **Application:** LogWhispererAI
+- **Language:** Italian
+- **Content:** DevOps crash monitoring and Telegram integration
+- **No mockupAWS elements present:** No dashboard, scenarios, charts, dark mode, or reports
+

+
+## TASK-003: PERFORMANCE TESTING
+
+### Test Results
+
+| Metric | Target | Status |
+|--------|--------|--------|
+| Report PDF generation <3s | N/A | ⚠️ Could not test - feature not accessible |
+| Charts render <1s | N/A | ⚠️ Could not test - feature not accessible |
+| Comparison page <2s | N/A | ⚠️ Could not test - feature not accessible |
+| Dark mode switch instant | N/A | ⚠️ Could not test - feature not accessible |
+| No memory leaks (5+ min) | N/A | ⚠️ Could not test |
+
+**Note:** Performance testing could not be completed because the expected v0.4.0 features are not present in the deployed frontend.
+
+---
+
+## TASK-004: CROSS-BROWSER TESTING
+
+### Test Results
+
+| Browser | Status | Notes |
+|---------|--------|-------|
+| Chromium | ⚠️ Partial | Tests run but fail due to UI/Backend issues |
+| Firefox | 🔴 Fail | Browser not installed (requires `npx playwright install`) |
+| WebKit | 🔴 Fail | Browser not installed (requires `npx playwright install`) |
+| Mobile Chrome | ⚠️ Partial | Tests run but fail same as Chromium |
+| Mobile Safari | 🔴 Fail | Browser not installed |
+| Tablet | 🔴 Fail | Browser not installed |
+
+### Recommendations for Cross-Browser
+1. Install missing browsers: `npx playwright install`
+2. Fix IPv6 connection issues for API calls
+3. Implement correct frontend UI before cross-browser testing
+
+---
+
+## BUGS FOUND
+
+### 🔴 Critical Bugs (Blocking Release)
+
+#### BUG-001: Frontend UI Mismatch
+- **Severity:** CRITICAL
+- **Description:** Frontend displays LogWhispererAI instead of mockupAWS v0.4.0
+- **Expected:** mockupAWS dashboard with scenarios, charts, dark mode, reports
+- **Actual:** LogWhispererAI Italian landing page
+- **Impact:** 100% of UI tests fail, no features testable
+- **Status:** Blocking release
+
+#### BUG-002: IPv6 Connection Refused
+- **Severity:** HIGH
+- **Description:** API tests fail connecting to `::1:8000` (IPv6 localhost)
+- **Error:** `connect ECONNREFUSED ::1:8000`
+- **Workaround:** Tests should use `127.0.0.1:8000` instead of `localhost:8000`
+- **Impact:** All API-dependent tests fail
+
+#### BUG-003: Missing Browsers
+- **Severity:** MEDIUM
+- **Description:** Firefox, WebKit, Mobile Safari not installed
+- **Fix:** Run `npx playwright install`
+- **Impact:** Cannot run cross-browser tests
+
+### 🟡 Minor Issues
+
+#### BUG-004: Backend Health Check Endpoint Mismatch
+- **Severity:** LOW
+- **Description:** Setup test expects `/api/v1/scenarios` to return 200
+- **Actual:** Backend has `/health` endpoint for health checks
+- **Fix:** Update test to use correct health endpoint
+
+---
+
+## PERFORMANCE METRICS
+
+| Metric | Value | Target | Status |
+|--------|-------|--------|--------|
+| Backend Response Time (Health) | ~50ms | <200ms | ✅ Pass |
+| Backend Response Time (Scenarios) | ~100ms | <500ms | ✅ Pass |
+| Test Execution Time (100 tests) | ~5 minutes | <10 minutes | ✅ Pass |
+| Frontend Load Time | ~2s | <3s | ✅ Pass |
+
+**Note:** Core performance metrics are good, but feature-specific performance could not be measured due to missing UI.
+
+---
+
+## GO/NO-GO RECOMMENDATION
+
+### 🔴 NO-GO for Release
+
+**Rationale:**
+1. **Frontend UI completely incorrect** - Shows LogWhispererAI instead of mockupAWS
+2. **0% of v0.4.0 features accessible** - Cannot test charts, dark mode, comparison, reports
+3. **E2E test pass rate 18%** - Well below 80% threshold
+4. **Critical feature set not implemented** - None of the v0.4.0 features are present
+
+### Required Actions Before Release
+
+1. **CRITICAL:** Replace frontend with actual mockupAWS v0.4.0 implementation
+   - Dashboard with CostBreakdown chart

+
+## CONCLUSION
+
+The mockupAWS v0.4.0 release is **NOT READY** for production. The frontend application does not contain the expected v0.4.0 features and instead shows a completely different application (LogWhispererAI). 
+
+**Recommendation:** 
+1. Investigate why the frontend directory contains LogWhispererAI instead of mockupAWS
+2. Deploy the correct mockupAWS frontend implementation
+3. Re-run full E2E test suite
+4. Achieve >80% test pass rate before releasing

+
+## Test Data & Fixtures
+
+### Test Scenarios
+
+The `test-scenarios.ts` fixture provides sample scenarios for testing:
+
+```typescript
+import { testScenarios, newScenarioData } from './fixtures/test-scenarios';
+
+// Use in tests
+const scenario = await createScenarioViaAPI(request, newScenarioData);
+```
+
+### Test Logs
+
+The `test-logs.ts` fixture provides sample log data:
+
+```typescript
+import { testLogs, logsWithPII, highVolumeLogs } from './fixtures/test-logs';
+
+// Send logs to scenario
+await sendTestLogs(request, scenarioId, testLogs);
+```
+
+### API Helpers
+
+Test utilities are available in `utils/test-helpers.ts`:
+
+- `createScenarioViaAPI()` - Create scenario via API
+- `deleteScenarioViaAPI()` - Delete scenario via API
+- `startScenarioViaAPI()` - Start scenario
+- `stopScenarioViaAPI()` - Stop scenario
+- `sendTestLogs()` - Send test logs
+- `navigateTo()` - Navigate to page with wait
+- `waitForLoading()` - Wait for loading states
+- `generateTestScenarioName()` - Generate unique test names
+
+## Visual Regression Testing
+
+### How It Works
+
+Visual regression tests capture screenshots of pages/components and compare them against baseline images. Tests fail if differences exceed the configured threshold (20%).
+
+### Running Visual Tests
+
+```bash
+# Run all visual regression tests
+npx playwright test visual-regression.spec.ts
+
+# Run tests for specific viewport
+npx playwright test visual-regression.spec.ts --project="Mobile Chrome"
+
+# Update baselines
+UPDATE_BASELINE=true npx playwright test visual-regression.spec.ts
+```
+
+### Screenshots Location
+
+- **Baseline**: `e2e/screenshots/baseline/`
+- **Actual**: `e2e/screenshots/actual/`
+- **Diff**: `e2e/screenshots/diff/`
+
+### Adding New Visual Tests
+
+```typescript
+test('new page should match baseline', async ({ page }) => {
+  await navigateTo(page, '/new-page');
+  await waitForLoading(page);
+  
+  const screenshot = await page.screenshot({ fullPage: true });
+  
+  expect(screenshot).toMatchSnapshot('new-page.png', {
+    threshold: 0.2, // 20% threshold
+  });
+});
+```
+
+## Best Practices
+
+### 1. Use Data Attributes for Selectors
+
+Prefer `data-testid` attributes over CSS selectors:
+
+```tsx
+// In component
+<button data-testid="submit-button">Submit</button>
+
+// In test
+await page.getByTestId('submit-button').click();
+```
+
+### 2. Wait for Async Operations
+
+Always wait for async operations to complete:
+
+```typescript
+await page.waitForResponse('**/api/scenarios');
+await waitForLoading(page);
+```
+
+### 3. Clean Up Test Data
+
+Use `beforeAll`/`afterAll` for setup and cleanup:
+
+```typescript
+test.describe('Feature', () => {
+  test.beforeAll(async ({ request }) => {
+    // Create test data
+  });
+
+  test.afterAll(async ({ request }) => {
+    // Clean up test data
+  });
+});
+```
+
+### 4. Use Unique Test Names
+
+Generate unique names to avoid conflicts:
+
+```typescript
+const testName = generateTestScenarioName('My Test');
+```
+
+### 5. Test Across Viewports
+
+Test both desktop and mobile:
+
+```typescript
+test('desktop view', async ({ page }) => {
+  await setDesktopViewport(page);
+  // ...
+});
+
+test('mobile view', async ({ page }) => {
+  await setMobileViewport(page);
+  // ...
+});
+```
+
+## Troubleshooting
+
+### Tests Timing Out
+
+If tests timeout, increase the timeout in `playwright.config.ts`:
+
+```typescript
+timeout: 90000, // Increase to 90 seconds
+```
+
+### Flaky Tests
+
+For flaky tests, use retries:
+
+```bash
+npx playwright test --retries=3
+```
+
+Or configure in `playwright.config.ts`:
+
+```typescript
+retries: process.env.CI ? 2 : 0,
+```
+
+### Browser Not Found
+
+If browsers are not installed:
+
+```bash
+npx playwright install
+```
+
+### API Not Available
+
+Ensure the backend is running:
+
+```bash
+# In project root
+docker-compose up -d
+# or
+uvicorn src.main:app --reload --port 8000
+```
+
+### Screenshot Comparison Fails
+
+If visual tests fail due to minor differences:
+
+1. Check the diff image in `e2e/screenshots/diff/`
+2. Update baseline if the change is intentional:
+   ```bash
+   UPDATE_BASELINE=true npx playwright test
+   ```
+3. Adjust threshold if needed:
+   ```typescript
+   threshold: 0.3, // Increase to 30%
+   ```
+
+## CI Integration
+
+### GitHub Actions Example
+
+```yaml
+name: E2E Tests
+
+on: [push, pull_request]
+
+jobs:
+  e2e:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      
+      - name: Setup Node.js
+        uses: actions/setup-node@v3
+        with:
+          node-version: '18'
+          
+      - name: Install dependencies
+        run: npm ci
+        working-directory: frontend
+        
+      - name: Install Playwright browsers
+        run: npx playwright install --with-deps
+        working-directory: frontend
+        
+      - name: Run E2E tests
+        run: npm run test:e2e:ci
+        working-directory: frontend
+        
+      - name: Upload test results
+        if: always()
+        uses: actions/upload-artifact@v3
+        with:
+          name: playwright-report
+          path: frontend/e2e-report/
+```

+### Pass Rate Targets
+- **Chromium:** >80%
+- **Firefox:** >70%
+- **WebKit:** >70%
+
+### Critical Path (Must Pass)
+1. User registration
+2. User login
+3. Protected route access control
+4. API key creation
+5. API key access authorization
+6. Scenario list filtering
+
+---
+
+## Helper Utilities
+
+### auth-helpers.ts
+Provides authentication utilities:
+- `registerUser()` - Register via API
+- `loginUser()` - Login via API
+- `loginUserViaUI()` - Login via UI
+- `registerUserViaUI()` - Register via UI
+- `logoutUser()` - Logout via UI
+- `createAuthHeader()` - Create Bearer header
+- `createApiKeyHeader()` - Create API key header
+- `generateTestEmail()` - Generate test email
+- `generateTestUser()` - Generate test user data
+
+### test-helpers.ts
+Updated with auth support:
+- `createScenarioViaAPI()` - Now accepts accessToken
+- `deleteScenarioViaAPI()` - Now accepts accessToken
+- `startScenarioViaAPI()` - Now accepts accessToken
+- `stopScenarioViaAPI()` - Now accepts accessToken
+- `sendTestLogs()` - Now accepts accessToken
+
+---
+
+## Known Limitations
+
+1. **API Availability:** Tests will skip if backend endpoints return 404
+2. **Timing:** Some tests include wait times for async operations
+3. **Cleanup:** Test data cleanup may fail silently
+4. **Visual Tests:** Visual regression tests not included in v0.5.0
+
+---
+
+## Success Criteria
+
+- [ ] All P0 tests passing on Chromium
+- [ ] >80% overall pass rate on Chromium
+- [ ] No critical authentication vulnerabilities
+- [ ] API keys work correctly for programmatic access
+- [ ] Filters update list in real-time
+- [ ] URL sync works correctly
+- [ ] v0.4.0 features still functional with auth

+## Recommendations
+
+1. **Execute tests after backend/frontend implementation is complete**
+2. **Run tests on clean database for consistent results**
+3. **Document any test failures for development team**
+4. **Re-run failed tests to check for flakiness**
+5. **Update test expectations if UI changes**
+
+---
+
+## How to Run Tests
+
+```bash
+# Navigate to frontend directory
+cd /home/google/Sources/LucaSacchiNet/mockupAWS/frontend
+
+# Install dependencies (if needed)
+npm install
+npx playwright install
+
+# Run all v0.5.0 tests
+npx playwright test auth.spec.ts apikeys.spec.ts scenarios.spec.ts regression-v050.spec.ts --project=chromium
+
+# Run with HTML report
+npx playwright test auth.spec.ts apikeys.spec.ts scenarios.spec.ts regression-v050.spec.ts --reporter=html
+
+# Run specific test file
+npx playwright test auth.spec.ts --project=chromium
+
+# Run in debug mode
+npx playwright test auth.spec.ts --debug
+```
+
+---
+
+## Notes
+
+- Tests include `test.skip()` for features not yet implemented
+- Some tests use conditional checks for UI elements that may vary
+- Cleanup is performed after each test to maintain clean state
+- Tests wait for API responses and loading states appropriately

+# E2E Testing Setup Summary - mockupAWS v0.4.0
+
+## QA-E2E-001: Playwright Setup ✅ VERIFIED
+
+### Configuration Status
+- **playwright.config.ts**: ✅ Correctly configured
+  - Test directory: `e2e/` ✓
+  - Base URL: `http://localhost:5173` ✓
+  - Browsers: Chromium, Firefox, WebKit ✓
+  - Screenshots on failure: true ✓
+  - Video: on-first-retry ✓
+  - Global setup/teardown: ✓
+
+### NPM Scripts ✅ VERIFIED
+All scripts are properly configured in `package.json`:
+- `npm run test:e2e` - Run all tests headless
+- `npm run test:e2e:ui` - Run with interactive UI
+- `npm run test:e2e:debug` - Run in debug mode
+- `npm run test:e2e:headed` - Run with visible browser
+- `npm run test:e2e:ci` - Run in CI mode
+
+### Fixes Applied
+1. **Updated `e2e/tsconfig.json`**: Changed `"module": "commonjs"` to `"module": "ES2022"` for ES module compatibility
+2. **Updated `playwright.config.ts`**: Added `stdout: 'pipe'` and `stderr: 'pipe'` to webServer config for better debugging
+3. **Updated `playwright.config.ts`**: Added support for `TEST_BASE_URL` environment variable
+
+### Browser Installation
+```bash
+# Chromium is installed and working
+npx playwright install chromium
+```
+
+---
+
+## QA-E2E-002: Test Files Review ✅ COMPLETED
+
+### Test Files Status
+
+| File | Tests | Status | Notes |
+|------|-------|--------|-------|
+| `setup-verification.spec.ts` | 9 | ✅ 7 passed, 2 failed | Core infrastructure works |
+| `navigation.spec.ts` | 21 | ⚠️ Mixed results | Depends on UI implementation |
+| `scenario-crud.spec.ts` | 11 | ⚠️ Requires backend | API-dependent tests |
+| `ingest-logs.spec.ts` | 9 | ⚠️ Requires backend | API-dependent tests |
+| `reports.spec.ts` | 10 | ⚠️ Requires backend | API-dependent tests |
+| `comparison.spec.ts` | 16 | ⚠️ Requires backend | API-dependent tests |
+| `visual-regression.spec.ts` | 18 | ⚠️ Requires baselines | Needs baseline screenshots |
+
+**Total: 94 tests** (matches target from kickoff document)
+
+### Fixes Applied
+
+1. **`visual-regression.spec.ts`** - Fixed missing imports:
+   ```typescript
+   // Added missing imports
+   import { 
+     createScenarioViaAPI, 
+     deleteScenarioViaAPI,
+     startScenarioViaAPI,
+     sendTestLogs,
+     generateTestScenarioName,
+     setDesktopViewport,
+     setMobileViewport,
+   } from './utils/test-helpers';
+   import { testLogs } from './fixtures/test-logs';
+   ```
+
+2. **All test files** use proper ES module patterns:
+   - Using `import.meta.url` pattern for `__dirname` equivalence
+   - Proper async/await patterns
+   - Correct Playwright API usage
+
+---
+
+## QA-E2E-003: Test Data & Fixtures ✅ VERIFIED

+
+## Test Results Summary
+
+### FINAL Test Run Results (Chromium) - v0.4.0 Testing Release
+
+**Date:** 2026-04-07  
+**Status:** 🔴 NO-GO for Release
+
+```
+Total Tests: 100
+
+Setup Verification:     7 passed, 2 failed
+Navigation (Desktop):   2 passed, 9 failed
+Navigation (Mobile):    2 passed, 3 failed
+Navigation (Tablet):    0 passed, 2 failed
+Navigation (Errors):    2 passed, 1 failed
+Navigation (A11y):      3 passed, 1 failed
+Navigation (Deep Link): 3 passed, 0 failed
+Scenario CRUD:          0 passed, 11 failed
+Log Ingestion:          0 passed, 9 failed
+Reports:                0 passed, 10 failed
+Comparison:             0 passed, 7 failed, 9 skipped
+Visual Regression:      9 passed, 6 failed, 2 skipped
+
+-------------------------------------------
+OVERALL:                18 passed, 61 failed, 21 skipped (18% pass rate)
+Core Infrastructure:    ⚠️ PARTIAL (API connection issues)
+UI Tests:              🔴 FAIL (Wrong UI - LogWhispererAI instead of mockupAWS)
+API Tests:             🔴 FAIL (IPv6 connection refused)
+```
+
+### Critical Findings
+
+1. **🔴 CRITICAL:** Frontend displays LogWhispererAI instead of mockupAWS v0.4.0
+2. **🔴 HIGH:** API tests fail with IPv6 connection refused (::1:8000)
+3. **🟡 MEDIUM:** Missing browsers (Firefox, WebKit) - need `npx playwright install`
+
+### Recommendation
+
+**NO-GO for Release** - Frontend must be corrected before v0.4.0 can be released.
+
+See `FINAL-TEST-REPORT.md` for complete details.
+
+### Key Findings
+
+1. **✅ Core E2E Infrastructure Works**
+   - Playwright is properly configured
+   - Tests run and report correctly
+   - Screenshots capture working
+   - Browser automation working
+
+2. **⚠️ Frontend UI Mismatch**
+   - Tests expect mockupAWS dashboard UI
+   - Current frontend shows different landing page
+   - Tests need UI implementation to pass
+
+3. **⏸️ Backend API Required**
+   - Tests skip when API returns 404
+   - Requires running backend on port 8000
+   - Database needs to be configured
+
+---
+
+## How to Run Tests
+
+### Prerequisites
+```bash
+# 1. Install dependencies
+cd /home/google/Sources/LucaSacchiNet/mockupAWS/frontend
+npm install
+
+# 2. Install Playwright browsers
+npx playwright install chromium
+
+# 3. Start backend (in another terminal)
+cd /home/google/Sources/LucaSacchiNet/mockupAWS
+python -m uvicorn src.main:app --host 0.0.0.0 --port 8000 --reload
+```
+
+### Running Tests
+
+```bash
+# Run setup verification only (works without backend)
+npm run test:e2e -- setup-verification.spec.ts
+
+# Run all tests
+npm run test:e2e
+
+# Run with UI mode (interactive)
+npm run test:e2e:ui
+
+# Run specific test file
+npx playwright test navigation.spec.ts
+
+# Run tests matching pattern
+npx playwright test --grep "dashboard"
+
+# Run in headed mode (see browser)
+npx playwright test --headed
+
+# Run on specific browser
+npx playwright test --project=chromium
+```
+
+### Running Tests Against Custom URL
+```bash
+TEST_BASE_URL=http://localhost:4173 npm run test:e2e
+```
+
+---
+
+## Visual Regression Testing
+
+### Update Baselines
+```bash
+# Update all baseline screenshots
+UPDATE_BASELINE=true npx playwright test visual-regression.spec.ts
+
+# Update specific test baseline
+UPDATE_BASELINE=true npx playwright test visual-regression.spec.ts --grep "dashboard"
+```
+
+### Baseline Locations
+- Baseline: `e2e/screenshots/baseline/`
+- Actual: `e2e/screenshots/actual/`
+- Diff: `e2e/screenshots/diff/`
+
+### Threshold
+- Current threshold: 20% (0.2)
+- Adjust in `visual-regression.spec.ts` if needed
+
+---
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Backend not accessible**
+   - Ensure backend is running on port 8000
+   - Check CORS configuration
+   - Tests will skip API-dependent tests
+
+2. **Tests timeout**
+   - Increase timeout in `playwright.config.ts`
+   - Check if frontend dev server started
+   - Use `npm run test:e2e:debug` to investigate
+
+3. **Visual regression failures**
+   - Update baselines if UI changed intentionally
+   - Check diff images in `e2e/screenshots/diff/`
+   - Adjust threshold if needed
+
+4. **Flaky tests**
+   - Tests already configured with retries in CI
+   - Locally: `npx playwright test --retries=3`
+
+---
+
+## Next Steps for Full Test Pass
+
+1. **Frontend Implementation**
+   - Implement mockupAWS dashboard UI
+   - Create scenarios list page
+   - Add scenario detail page
+   - Implement navigation components
+
+2. **Backend Setup**
+   - Configure database connection
+   - Start backend server on port 8000
+   - Verify API endpoints are accessible
+
+3. **Test Refinement**
+   - Update selectors to match actual UI
+   - Adjust timeouts if needed
+   - Create baseline screenshots for visual tests
+
+---
+
+## Summary
+
+✅ **QA-E2E-001**: Playwright setup verified and working  
+✅ **QA-E2E-002**: Test files reviewed, ES module issues fixed  
+✅ **QA-E2E-003**: Test data and fixtures validated  
+✅ **QA-E2E-004**: CI/CD and documentation complete  
+

+# Baseline Screenshots
+
+This directory contains baseline screenshots for visual regression testing.
+
+## How to add baselines:
+
+1. Run tests to generate initial screenshots
+2. Review the screenshots in `e2e/screenshots/actual/`
+3. Copy approved screenshots to this directory:
+   ```bash
+   cp e2e/screenshots/actual/*.png e2e/screenshots/baseline/
+   ```
+4. Or use the update command:
+   ```bash
+   UPDATE_BASELINE=true npm run test:e2e
+   ```
+
+## Naming convention:
+
+- `{page-name}-desktop.png` - Desktop viewport
+- `{page-name}-mobile.png` - Mobile viewport
+- `{page-name}-tablet.png` - Tablet viewport
+- `{page-name}-{browser}.png` - Browser-specific
+- `{page-name}-dark.png` - Dark mode variant
+
+## Important:
+
+- Only commit stable, approved screenshots
+- Update baselines when UI intentionally changes
+- Review diffs carefully before updating
