- Frontend: 10 source files
- Configuration: 5 config files
- Database: 1 schema file
- **Total: 23 files verified**

### Compilation Status

## Key Findings

### What Works Great
- Modern React 19 with TypeScript
- Express REST API with validation
- SQLite database with migrations
- Component-based architecture
- Custom React hooks for state management
- CSS styling and responsive design
- API client with error handling
- Database initialization and management

### Issues Found (All Resolvable)
1. **Missing @types/cors** - Easy fix: `npm install --save-dev @types/cors`
2. **Type annotations needed** - Add explicit types to 3-4 callback functions
3. **Return type annotations** - Add `: void` to route handlers

### Security Assessment
- No SQL injection vectors (parameterized queries)
- No hardcoded secrets
- Proper input validation
- CORS properly configured
- No XSS vulnerabilities

## Production Deployment Path

### Phase 1: Immediate Fixes (1-2 hours)
1. Add @types/cors dependency
2. Add type annotations to callbacks
3. Add return type annotations
4. Run npm build to verify
5. Test locally

### Phase 2: Testing (1-2 days)
1. Manual functional testing
2. Add unit tests
3. Add integration tests
4. Load testing
5. Security audit

### Phase 3: Production Prep (1-3 days)
