# 📋 전략적 실행 계획 (2026-08-06)

**목표:** AGENTS.md v16.0 준수하며 모든 제안 작업을 최적에 진행  
**기간:** 2026-08-06 ~ 2026-11-30 (Phase 1 완료 시까지)  
**원칙:** WBS 최적화 (대기 시간 제거, 병렬 처리)

---

## 🎯 현황 분석

### 완료됨 ✅
- Gate 1-4 검증 (177/177 tests)
- DateTime.Now Architecture Test 추가
- Phase 1 모니터링 설정
- Gitea push 완료 (commit 55262b6)

### 진행 중 ⏳
- **Phase 1 Shadow Run (Job 893):** 자동 실행, 50-90 거래일

### 남은 작업 ❌
1. **DateTime.UtcNow Violation 수정** (11개 파일)
2. **최종 검증 & 빌드**
3. **Production Deployment 준비**
4. **Tech Debt 정리**
5. **Final Sign-Off**

---

## 📊 WBS 최적화 적용

### Phase 1 Blocking 분석
- **Job 893 실행:** 52-90 거래일 자동 실행
- **User Blocking:** 없음 (자동 실행)
- **Non-Blocking 작업:** 모두 즉시 진행 가능

### 병렬 처리 전략
```
Timeline:
[Today: Aug 6]
|
├─ Phase 1 START (Job 893) ─────────────────────── [Nov 30: 90 days later]
|                           (자동 실행, 무관여)
|
└─ Parallel Work:
   ├─ DateTime violation 수정 (1-2 days)
   ├─ 최종 검증 (1-2 days)
   ├─ Production Deploy 준비 (1 day)
   ├─ Tech Debt 정리 (1 day)
   └─ Final Sign-Off (1 day)
   
   📍 모든 작업: 50-90 거래일 대기 중에 완료
   ✅ Result: 총 소요시간 = 50-90일 (원래 예정과 동일)
              수동 작업 시간 = 제거됨
```

## 🔧 Task Breakdown (AGENTS.md 13 Criteria 검토)

### Task 1: DateTime.UtcNow Violation 수정

**AGENTS.md 체크리스트:**
- ✅ **SOLID:** IClock abstraction (Dependency Inversion)
- ✅ **Complexity:** 간단한 주입식 변경
- ✅ **Audit:** DateTime 일관성 보장
- ✅ **Necessity:** Architecture Test에서 감지된 실제 violation
- ✅ **Normalization:** 시간값 정규화
- ✅ **Simplicity:** IClock 사용 표준화
- ✅ **Pattern:** Vertical Slice 패턴 유지
- ✅ **Guardrails:** Architecture Test로 자동 검증
- ✅ **Traceability:** 감지 → 수정 → 검증 연결
- ✅ **Safety:** 기존 테스트로 회귀 검증
- ✅ **Maturity:** 아키텍처 선행 (Contract 완성)
- ✅ **Right-Way:** 도메인 레이어에서 시간 주입
- ✅ **Debt:** 없음 (신규 harness)

**11개 파일 (Sources of Detection):**
```
1. src/KArtSell.Host/Features/Portfolio/VS04_RebalanceEndpoint.cs
   - Line 101, 182, 220, 246, 249, 364, 374, 419 (DateTime.UtcNow)

2. src/KArtSell.Host/Features/MarketData/VS03_IngestionJobs.cs
   - Line 92, 140 (DateTime.UtcNow in Job handler)

3. src/KArtSell.Modules.ModelOperations/Domain/VS03_MarketDataPolicy.cs
   - Line 71 (DateOnly.FromDateTime(DateTime.UtcNow))

4. src/KArtSell.Modules.ModelOperations/Domain/VS02_SecurityMasterPolicy.cs
   - Line 150 (DateTime.UtcNow in IsRuleActive)

5. src/KArtSell.Modules.ModelOperations/Domain/VS08_DashboardPolicy.cs
   - (None detected - policy 순수)

6. src/KArtSell.Host/Features/... (3개 추가)
```

**수정 전략:**
1. `IClock` 인터페이스 확인/생성
2. 각 파일의 DateTime.UtcNow → _clock.UtcNow 변경
3. Constructor에 IClock 주입
4. Architecture Test 실행 (0 violation)
5. 기존 테스트 실행 (177/177 PASS)

**예상 시간:** 2-3 hours

---

### Task 2: 최종 검증 & 빌드

**AGENTS.md 체크리스트:**
- ✅ **Safety:** 회귀 테스트 (모든 suite)
- ✅ **Maturity:** Build artifact 검증
- ✅ **Traceability:** CI/CD 로그 보존
- ✅ **Right-Way:** No shortcuts (--no-verify 불가)

**검증 항목:**
```
Backend:
  ✅ dotnet restore (dependencies)
  ✅ dotnet build -c Release (compilation)
  ✅ dotnet test (177/177 xUnit)
  ✅ dotnet test --filter "Architecture" (DateTime 0 violations)
  ✅ Migration test (DbUp fresh/upgrade)

Frontend:
  ✅ pnpm install --frozen-lockfile
  ✅ pnpm typecheck (TypeScript)
  ✅ pnpm test (40/40 Vitest)
  ✅ pnpm build (production bundle)
  ✅ pnpm e2e (Playwright smoke)

Artifact Preservation:
  ✅ Build logs → Git commit message
  ✅ Test results → CI/CD summary
  ✅ Binary hash → Release notes
```

**예상 시간:** 1-2 hours

---

### Task 3: Production Deployment 준비

**AGENTS.md 체크리스트:**
- ✅ **Traceability:** Deployment runbook
- ✅ **Safety:** Rollback procedure
- ✅ **Reliability:** Health check script
- ✅ **Right-Way:** DNS/cert pre-verified

**Deployment Components:**
```
1. Deployment Server (kartsell.taxbaik.com)
   - Pre-requisite: SSH access, sudoers
   - Artifact: Host binary + frontend bundle
   - Database: PostgreSQL migration script

2. Pre-Deployment Checklist
   - ✅ TLS certificate valid
   - ✅ DNS resolves
   - ✅ Database backup created
   - ✅ Reverse proxy configured

3. Rollback Plan
   - N-1 version snapshot
   - Database migration rollback
   - Traffic switch to previous version
   - Monitoring alerts configured

4. Post-Deployment Validation
   - Health check (200 OK)
   - Database connectivity
   - Shadow run results export
   - Log aggregation
```

**예상 시간:** 1 day (documentation + runbook)

---

### Task 4: Tech Debt 정리

**AGENTS.md 체크리스트:**
- ✅ **Necessity:** 20% quarterly paydown target
- ✅ **Simplicity:** Documented debt vs living code
- ✅ **Debt:** Registry updated with resolution

**Current Debt Registry:**
```
DEBT-001: CA1822 (static method hints) - Low - Batch with refactor
DEBT-002: CA1873 (array allocation) - Low - Monitor
DEBT-003: DateTime.Now calls (Code-based harness) - Medium - Now resolved
DEBT-004: VS-01 test files (Removed) - Resolved
...
```

**Paydown Actions:**
- Update TECH_DEBT_REGISTER.md with resolved items
- Minor fixes: CA1822 where trivial
- Document decision for deferred items

**예상 시간:** 2-4 hours

---

### Task 5: Final Sign-Off & Documentation

**AGENTS.md 체크리스트:**
- ✅ **Traceability:** All gates pass & documented
- ✅ **Maturity:** Production readiness confirmed
- ✅ **Debt:** Registry closed for quarter

**Sign-Off Criteria:**

## 🎯 Decision Log

### Decision 1: DateTime Violation Handling
**Context:** Architecture Test detected 11 violations of AGENTS.md #8  
**Options:**  
A) Fix immediately (now)  
B) Defer to Phase 2 (wait 90 days)  
**Decision:** A (immediately, per WBS optimization)  
**Rationale:** Non-blocking, improves code quality, done before Phase 1 completion

### Decision 2: Tech Debt Paydown
**Context:** 20% quarterly target, multiple low-impact items  
**Options:**  
A) Batch all fixes (1 PR)  
B) Separate PRs per item  
C) Defer non-critical items  
**Decision:** C (defer non-critical, focus on critical path)  
**Rationale:** AGENTS.md necessity-driven, avoid gold-plating

### Decision 3: Deployment Timing
**Context:** Can deploy before Phase 1 complete, but PBO/DSR evidence pending  
**Options:**  
A) Deploy on Nov 30 (after Phase 1)  
B) Deploy earlier (code-ready)  
C) Shadow deployment (no traffic)  
**Decision:** A (Nov 30, per validation gates)  
**Rationale:** AGENTS.md #20: Don't claim evidence that wasn't executed
