📊 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

🎯 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
