## Project Memory (Steering System)
**CRITICAL: Always check steering files before starting any task**
Before beginning work, **ALWAYS** read the following files if they exist in the `steering/` directory:
**IMPORTANT: Always read the ENGLISH versions (.md) - they are the reference/source documents.**
- **`steering/structure.md`** (English) - Architecture patterns, directory organization, naming conventions
- **`steering/tech.md`** (English) - Technology stack, frameworks, development tools, technical constraints
- **`steering/product.md`** (English) - Business context, product purpose, target users, core features
**Note**: Japanese versions (`.ja.md`) are translations only. Always use English versions (.md) for all work.

### Quality Gate: ❌ FAILED
- 4 critical issues must be resolved before implementation
---
### 🔴 Critical Issues
#### DES-001: SRP Violation in UserManager Class
**Location**: Section 4.2 - Component Design
**Category**: SOLID (SRP)
**Severity**: Critical
**Current Design:**
```
UserManager
├── authenticateUser()
├── registerUser()
├── sendNotificationEmail()
├── generateReport()
├── updateUserPreferences()
└── backupUserData()
```
**Issue:**
UserManager class has 6+ unrelated responsibilities. This violates SRP and creates a "God Class" anti-pattern.
**Recommendation:**
Split into focused classes:
```
AuthenticationService → authenticateUser()
UserRegistrationService → registerUser()
NotificationService → sendNotificationEmail()
ReportingService → generateReport()
UserPreferenceService → updateUserPreferences()
BackupService → backupUserData()
```
**Your Decision:**
- [ ] Accept recommendation (split into 6 classes)
- [ ] Modify (specify alternative structure)
- [ ] Reject with ADR (document why monolithic design is preferred)
---
#### DES-SEC-003: Missing Input Validation Design
**Location**: Section 5.1 - API Design
**Category**: Security
**Severity**: Critical
**Current Design:**
API endpoints accept user input without documented validation strategy.
**Issue:**
No input validation or sanitization design documented. Risk of injection attacks.
**Recommendation:**
Add input validation layer:
```
1. Define validation schema for each endpoint
2. Implement sanitization before processing
3. Return structured error responses for invalid input
4. Log validation failures for security monitoring
```
**Your Decision:**
- [ ] Accept recommendation
- [ ] Modify (specify your validation approach)
- [ ] Reject (provide justification)
```

### 11.4 Document Correction Process
修正適用時の処理フロー：
1. **バックアップ作成**: 修正前のドキュメントを `.backup` として保存
2. **変更適用**: 承認された修正をドキュメントに反映
3. **ADR生成**: 重要な設計決定についてADRを自動生成
4. **C4ダイアグラム更新**: アーキテクチャ変更時にダイアグラムを更新
5. **日本語版同期**: 英語版修正後、日本語版も同様に更新
```javascript
// Programmatic correction example
const { designReviewerSkill } = require('musubi-sdd/src/orchestration');
// Step 1: Execute review
const reviewResult = await designReviewerSkill.execute({
action: 'review',
documentPath: 'docs/design/architecture-v1.0.md',
focus: ['solid', 'security', 'patterns'],
outputFormat: 'interactive',
});
// Step 2: Apply corrections based on user decisions
const corrections = [
{ issueId: 'DES-001', action: 'accept' },
{ issueId: 'DES-002', action: 'modify', newDesign: 'Custom design...' },
{ issueId: 'DES-005', action: 'reject-with-adr', reason: 'Performance tradeoff' },
];
const correctionResult = await designReviewerSkill.execute({
action: 'correct',
documentPath: 'docs/design/architecture-v1.0.md',
corrections: corrections,
createBackup: true,
generateADRs: true,
updateJapanese: true,
});
console.log(correctionResult.changesApplied);
console.log(correctionResult.adrsCreated);

## 12. Constitutional Compliance (CONST-002, CONST-003)
This skill ensures compliance with:
- **Article 2 (Traceability)**: Links design decisions to requirements
- **Article 3 (Quality Assurance)**: Systematic quality checks before implementation
- **User-Driven Correction**: User maintains control over all document changes
- **ADR Documentation**: Rejected findings are documented with rationale
