- Should see login page
- Check browser console for errors
4. **Login Test**:
- Login with admin account
- Verify session persistence
- Check audit logs
5. **Analysis Test**:
- Create test analysis
- Wait for completion
- Verify results saved
### Performance Checks
```bash
# Check server resources
htop
# Check MySQL connections
mysql -e "SHOW PROCESSLIST;"
# Check PM2 status
pm2 status
# Check Nginx logs
sudo tail -f /var/log/nginx/access.log
sudo tail -f /var/log/nginx/error.log
```

- `GET /api/analyze/history` - Get user history
- `GET /api/analyze/:id` - Get analysis detail
- `DELETE /api/analyze/:id` - Delete analysis
**Admin** (8 endpoints):
- `GET /api/admin/dashboard` - Get dashboard stats

"success": true,
"data": { /* response data */ },
"message": "操作成功"
}
```
**Error**:
```json
{
"success": false,
"error": "ErrorType",
"message": "錯誤訊息"
}
```
---
## 5. Security Design
### 5.1 Authentication & Authorization
**Authentication Method**: Session-based
- Session storage: Server-side (in-memory)
- Cookie name: `5why.sid`
- Cookie attributes: `httpOnly`, `maxAge: 24h`
- Session duration: 24 hours
**Authorization Levels**:
1. **user**: Regular user (analysis creation, history viewing)
2. **admin**: Administrator (+ user management, system monitoring)
3. **super_admin**: Super administrator (+ all admin functions)
**Middleware Chain**:
```javascript
requireAuth requireAdmin requireSuperAdmin
Route Handler
```
### 5.2 Security Measures
**Password Security**:
- Algorithm: bcrypt
- Salt rounds: 10
- No plaintext storage
- Hash verification on login
**SQL Injection Prevention**:
- Parameterized queries (100% coverage)
- mysql2 prepared statements
- No string concatenation
**XSS Prevention**:
- React auto-escaping
- Helmet security headers
- CSP ready (disabled in dev)
**CSRF Protection**:
- SameSite cookies (recommended)
- Session-based authentication
- CORS configuration
**Rate Limiting**:
- Window: 15 minutes
- Limit: 100 requests per IP
- Applied to all /api/* routes
**Audit Logging**:
- All authentication events
- CRUD operations
- IP address tracking
- User agent logging
---
## 6. AI Integration Design
### 6.1 Ollama API Integration
**Endpoint**: `https://ollama_pjapi.theaken.com/api/generate`
**Request Flow**:
```
User Input → Backend → Ollama API → Parse Response → Save to DB
```
**Prompt Engineering**:
```javascript
const prompt = `
你是一個專業的根因分析專家。請使用 5 Why 分析法...
【發現的現象】
${finding}
【工作內容/背景】
${jobContent}
請從以下${perspectives.length}個角度進行分析:
${perspectives.map(p => `- ${perspectiveNames[p]}`).join('\n')}
請用${languageNames[outputLanguage]}回答...
`;
```
**Response Parsing**:
- JSON format expected
- 3 perspectives (technical, process, human)
- Each perspective: 5 whys, root cause, solution
- Error handling for malformed responses
### 6.2 Analysis State Machine
```
pending → processing → completed
failed
```
**States**:
- `pending`: Analysis created, waiting to process
- `processing`: Sent to Ollama, awaiting response
- `completed`: Successfully analyzed and saved
- `failed`: Error occurred during processing
---
## 7. Frontend Architecture
### 7.1 Component Hierarchy
```
App
├── AuthProvider
│ └── AppContent
│ ├── LoginPage (if not authenticated)
│ └── Layout (if authenticated)
│ ├── Navigation
│ ├── UserMenu
│ └── Page Content
│ ├── AnalyzePage
│ ├── HistoryPage
│ └── AdminPage
│ ├── DashboardTab
│ ├── UsersTab
│ ├── AnalysesTab
│ └── AuditTab
```
### 7.2 State Management
**Global State** (Context API):
- `AuthContext`: User authentication state
- `ToastContext`: Notification system (Phase 6)
**Local State** (useState):
- Component-specific UI state
- Form data
- Loading states
- Error messages
### 7.3 Routing Strategy
**Client-side routing**: State-based navigation
- No react-router (simplified)
- `currentPage` state in AppContent
- Navigation via `onNavigate` callback
**Pages**:

### 8.3 Environment Variables
**Required**:
- `DB_HOST`: MySQL host
- `DB_PORT`: MySQL port (33306)
- `DB_USER`: Database user
- `DB_PASSWORD`: Database password
- `DB_NAME`: Database name
- `SESSION_SECRET`: Session encryption key
- `OLLAMA_API_URL`: Ollama API endpoint
- `OLLAMA_MODEL`: AI model name
**Optional**:
- `NODE_ENV`: Environment (development/production)
- `PORT`: Server port (default: 3001)
- `CLIENT_PORT`: Frontend port (default: 5173)
---
## 9. Performance Considerations
### 9.1 Database Optimization
**Connection Pooling**:
- Pool size: 10 connections
- Queue limit: 0 (unlimited)
- Connection timeout: Default
**Indexes**:
- All foreign keys indexed
- Query optimization indexes on:
- `users.email`, `users.employee_id`
- `analyses.user_id`, `analyses.status`
- `audit_logs.user_id`, `audit_logs.created_at`
**Query Optimization**:
- Pagination on all list queries
- Lazy loading of related data
- Efficient JOIN operations
### 9.2 Caching Strategy
**Current**: No caching implemented
**Recommendations**:
- Session caching (Redis)
- Static asset caching (CDN)
- API response caching for stats
### 9.3 AI Response Time
**Typical Analysis Duration**: 30-60 seconds
- Depends on Ollama server load
- Network latency
- Model complexity
**Optimization**:
- Async processing (already implemented)
- Status updates to user
- Timeout handling (60s max)
---
## 10. Monitoring & Logging
### 10.1 Application Logging
**Audit Logs** (Database):
- Authentication events
- CRUD operations
- Admin actions
- IP addresses
**Server Logs** (Console):
- Request logging (development)
- Error logging (all environments)
- Database connection events
### 10.2 Monitoring Metrics
**Recommended Monitoring**:
- API response times
- Database query performance
- Session count
- Active users
- Analysis completion rate
- Error rates
**Tools** (Not implemented, recommended):
- PM2 for process management
- Winston for structured logging
- Prometheus + Grafana for metrics
---
## 11. Scalability
### 11.1 Current Limitations
- In-memory session storage (single server only)
- No horizontal scaling support
- Synchronous AI processing
### 11.2 Scaling Recommendations
**Horizontal Scaling**:
1. Move sessions to Redis
2. Load balancer (Nginx)
3. Multiple Node.js instances
4. Database read replicas
**Vertical Scaling**:
1. Increase server resources
2. MySQL optimization
3. Connection pool tuning
**AI Processing**:
1. Queue system (Bull/Redis)
2. Worker processes for AI calls
3. Multiple Ollama instances
---
## 12. Maintenance & Updates
### 12.1 Database Migrations
**Current**: Manual SQL execution
**Recommended**:
- Migration tool (Flyway/Liquibase)
- Version-controlled migrations
- Rollback capability
### 12.2 Backup Strategy
**Database Backups**:
- Daily full backups
- Point-in-time recovery
- Off-site storage
**Code Backups**:
- Git version control (Gitea)
- Regular commits
- Tag releases
### 12.3 Update Procedures
1. Test in development environment
2. Database migration (if needed)
3. Code deployment
4. Health check verification
5. Monitor logs
---
## 13. Known Limitations
1. **Single Language Output**: Analysis in selected language only (no on-the-fly translation)
2. **Session Storage**: In-memory (not suitable for multi-server)
3. **No Real-time Updates**: Page refresh required for new data
4. **Limited Error Recovery**: Failed analyses need manual retry
5. **No Data Export**: CSV export not yet implemented
---
## 14. Future Enhancements
### Phase 6-9 (Planned)
- Toast notification system
- CSV import/export
- Table sorting
- Enhanced loading states
- Security hardening
### Future Versions
- Multi-LLM support (Gemini, DeepSeek, OpenAI)
- PDF report generation
- Batch analysis processing
- Email notifications
- Two-factor authentication
- Real-time collaboration
- Mobile app
---

const prompt = `你是一位專精於「5 Why 根因分析法」的資深顧問。請嚴格遵循以下五大執行要項進行分析:
## 五大執行要項
### 1. 精準定義問題(描述現象,而非結論)
- 第一步必須客觀描述「發生了什麼事」,而非直接跳入「我認為是甚麼問題」
- 具體化包含人、事、時、地、物5W1H
### 2. 聚焦於「流程」與「系統」,而非「人」
- 若答案是「人為疏失」,請繼續追問:「為什麼系統允許這個疏失發生?」
- 原則:解決問題的機制,而非責備犯錯的人
### 3. 基於「事實」與「現場」,拒絕「猜測」
- 每一個「為什麼」的回答,都必須是可查證的事實
- 若無法確認,應標註需要驗證的假設
### 4. 邏輯的「雙向檢核」
- 順向檢查:若原因 X 發生,是否必然導致結果 Y
- 逆向檢查:若消除了原因 X結果 Y 是否就不會發生?
### 5. 止於「可執行的對策」
- 根本原因必須能對應到一個「永久性對策」(不再發生)
- 不僅是「暫時性對策」(如:重新訓練、加強宣導)
---
## 待分析內容
**Finding發現的問題/現象):** ${finding}
**工作內容背景:** ${jobContent}
---
## 輸出要求
請提供 **三個不同角度** 的 5 Why 分析,每個分析從不同的切入點出發(例如:流程面、系統面、管理面、設備面、環境面等)。
注意:
- 5 Why 的目的不是「湊滿五個問題」,而是穿透表面症狀直達根本原因
- 若在第 3 或第 4 個 Why 就已找到真正的根本原因,可以停止(設為 null
- 每個 Why 必須標註是「已驗證事實」還是「待驗證假設」
- 最終對策必須是「永久性對策」
⚠️ 重要:請使用 **${langName}** 語言回覆所有內容。
