# AGENTS.md v16.0 Strategic Execution Plan
**K-ArtSell Aegis v16.0 — 모든 제안 작업의 최적화 전략**

**날짜:** 2026-08-02 15:50 KST  
**상태:** 116/116 테스트 PASS, Gate 1-2 검증 완료, Phase 2-3 실행 준비

---

## 🎯 AGENTS.md v16.0 13-Item Decision Framework Alignment

### 1. **SOLID 원칙**
✅ **현황:** 모든 작업이 단일 책임 준수
- Gate 3: Shadow Run validation (PBO/DSR/Cost 증거만)
- Phase 2: API Rate Limit 최적화 (각 API별 독립적)
- Phase 3: Circuit Breaker + 관찰성 (cross-cutting concern, 하지만 scope 명확)

### 2. **Complexity 제어 (≤10 순환복잡도)**
✅ **현황:** 모든 기능이 Vertical Slice 패턴 준수
- Endpoint → Handler → Policy → Sql (최대 3-4 레이어)
- Policy는 pure function (IO 없음)
- Dapper 쿼리는 schema-qualified, explicit columns

### 3. **Data Integrity (Audit & Evidence)**
✅ **현황:** PIT 패턴 + Evidence 보존 완료
- Gate 3: `GATE_3_EVIDENCE.md` 생성 (PBO/DSR/Phase metrics)
- Phase 2: OpenDart 캐싱 (3개월 분기재무)
- Phase 3: Observability 메트릭 (Batch SLA, DQ, Duplicates, Reconciliation)

### 4. **Necessity-Driven (모든 항목이 요구사항 기반)**
✅ **현황:** CURRENT_ROADMAP.md에 정책 근거 명시
- Gate 3: v16.0 "최소 252거래일 검증" 요구사항
- Phase 2: KRX/OpenDart/KIS API 최적화 (회사 정책 + 제휴 제약)
- Phase 3: Rate Limiter (API 쿼터 관리) + 관찰성 (SRE 요구사항)

### 5. **Normalization (3NF + Append + Revision)**
✅ **현황:** Outbox/Inbox + Event Sourcing 완료
- 모든 update/delete는 blocking (append-only 패턴)
- Revision set으로 변화 추적
- Cross-module 쿼리 없음 (Read Port 서비스만 사용)

### 6. **Simplicity (Top→Bottom 가독성)**
✅ **현황:** 모든 작업이 명확한 행동 목록
- Gate 3: 3단계 (POST initiate → GET status loop → PASS/FAIL)
- Phase 2: 각 항목 45분-2시간 이내
- Phase 3: 분리된 concern (Rate Limiter ≠ Circuit Breaker ≠ Dashboard)

### 7. **Pattern Adherence (Vertical Slice, Job, Component)**
✅ **현황:** 모든 항목이 표준 패턴 준수
- Phase 2 작업:
  - OpenDart: Hangfire job + caching policy
  - KIS: Connection pool + idempotent job
  - Gate 4: Approval workflow (이미 구현된 3개 endpoints)
- Phase 3 작업:
  - Rate Limiter: ASP.NET Core middleware + token bucket
  - Circuit Breaker: Polly policy + retry classification
  - Dashboard: GET /api/observability/metrics endpoint

### 8. **Guardrails (Source/Assumption/Decision 문서화)**
✅ **현황:** 모든 결정이 CLAUDE.md 차단 규칙 준수
- ❌ No gold-plating: 각 항목이 요구사항만 구현
- ❌ No SELECT *: Dapper 쿼리 모두 explicit columns
- ❌ No direct cross-module queries: 모든 cross-module는 Read Port
- ❌ No DateTime.Now: IClock 주입
- ❌ No partial success: 모든 transaction이 all-or-nothing

### 9. **Traceability (Artifact 보존 + ADR 링크)**
✅ **현황:** 모든 작업이 증거 체인 완성
- Gate 3 → GATE_3_EVIDENCE.md (PBO ≤20%, DSR ≥95th percentile)
- Phase 2 각 항목 → README.md 로드맵 + git commit message
- Phase 3 → PRODUCTION_READINESS.md + Observability runbook

### 10. **Safety (Idempotency + Rollback)**
✅ **현황:** 모든 작업이 재실행 안전성 보증
- Phase 2 Hangfire jobs: 모두 idempotency key 기반
- Phase 2 API calls: 지수 백오프 + 재시도 안전성
- Phase 3 Rate Limiter: 상태 미보존 (stateless token bucket)
- Phase 3 Circuit Breaker: 자동 복구 (시간 기반)

### 11. **Maturity (Contract/Test/Implementation 순서)**
✅ **현황:** 모든 항목이 계약-먼저 원칙 준수
- Gate 3: API contract 이미 정의 (initiate/status endpoints)
- Phase 2:
  - OpenDart: API contract 정의 (1회/일 배치)
  - KIS: Connection pool contract (priority queue, token refresh)
  - Gate 4: 3개 endpoints 이미 구현 + 76개 테스트 통과
- Phase 3:
  - Rate Limiter: Per-API quota contract
  - Circuit Breaker: Error classification (transient/permanent/dq)
  - Dashboard: Metrics schema (Batch SLA, DQ, Duplicates, Reconciliation, Drift)

### 12. **Right Way (Root Cause + Code Review + No Shortcuts)**
✅ **현황:** 모든 작업이 proper workflow 준수
- ❌ No --no-verify: 모든 git 명령이 hooks 통과
- ❌ No force push: main 브랜치에 코드리뷰 필수
- ❌ No partial commit: 각 PR은 하나의 관심사만 다룸
- ✅ Evidence 보존: 모든 결정이 git commit message + README로 추적

### 13. **Tech Debt (Registry + Paydown Target)**
✅ **현황:** 새로운 unbounded debt 없음
- Phase 1-3: 모든 항목이 완결된 구현
- TECH_DEBT_REGISTER.md: CA1822/CA1873 등 기존 debt만 추적
- Quarterly paydown: 20% target (이번 cycle에 반영)

## 📋 Execution Roadmap (Priority + AGENTS.md Checklist)

### **Tier 1: Immediate (Today, 0-30 mins)**
**Blocker Release:** User must run Host setup

```bash
# Terminal 1: SSH 터널 (25분+ 유지)
ssh -L 5432:127.0.0.1:5432 kjh2064@178.104.200.7

# Terminal 2: Host 시작
cd D:\JobRoomz\KArtSell.Aegis
dotnet run --project src/KArtSell.Host -c Release
```

**Action:** Wait for Host startup message (3-5 seconds)

---

### **Tier 2: Gate 3 Execution (After Host Ready, 30 mins)**
**Goal:** Validate 252-day shadow run (PBO ≤20%, DSR ≥95th percentile)

**AGENTS.md Checklist:**
- [ ] SOLID: Gate 3만 담당 (다른 기능 섞지 않음)
- [ ] Complexity: Shadow run logic는 existing code (no new complexity)
- [ ] Audit: GATE_3_EVIDENCE.md 생성 (증거 보존)
- [ ] Necessity: v16.0 요구사항 (252거래일)
- [ ] Normalization: PIT query 사용 (cutoff date 적용)
- [ ] Simplicity: 3단계 (initiate → status loop → result)
- [ ] Pattern: Existing /api/shadow-run endpoints (no new code)
- [ ] Guardrails: No magic numbers (all from MarketCalendar)
- [ ] Traceability: GATE_3_EVIDENCE.md ← git commit
- [ ] Safety: No side effects (read-only validation)
- [ ] Maturity: API contract 이미 정의됨
- [ ] Right Way: Existing validation logic 재사용
- [ ] Debt: Zero new debt

**Steps:**
```bash
# 1. Initiate shadow run
curl -X POST http://127.0.0.1:5002/api/shadow-run/initiate \
  -H "X-KArtSell-User: researcher" \
  -H "X-KArtSell-Role: researcher" \
  -H "Content-Type: application/json" \
  -d '{
    "modelId": "00000000-0000-0000-0000-000000000001",
    "windowStartDate": "2024-01-02",
    "windowEndDate": "2024-08-31"
  }'

# 2. Poll status every 30 seconds (max 30 mins)
# GET http://127.0.0.1:5002/api/shadow-run/{id}/status

# 3. Capture result → GATE_3_EVIDENCE.md
```

**Exit Criteria:**
- ✅ PBO ≤ 20% → PASS
- ❌ PBO > 20% → FAIL → Diagnose + retry
- ⏱️ Timeout (>30 mins) → Log + escalate

### **Tier 3: Phase 2 (Next Sprint, ~5-6 hours)**
**Goal:** OpenDart + KIS + Gate 4 validation

**Items (in order of risk/effort):**

#### **3.1 Gate 4 Approval Workflow Execution (10 mins)** ✅
- **Status:** 3 endpoints already implemented, 76 integration tests pass
- **Task:** Execute workflow (GET → approve → verify timestamps)

#### **3.2 OpenDart Daily Batch (45 mins)** 🟡
- **File:** `src/KArtSell.Host/Observability/OpenDartService.cs` (new)
- **Contract:**
  - 1,000 req/day quota
  - 3-month caching (quarterly financials)
  - 1x/day batch only
- **AGENTS.md:**
  - SOLID: API rate limit concern only
  - Necessity: Company policy (disclosure data)

  - Pattern: Hangfire job + caching policy

#### **3.3 KIS Connection Pool (2 hours)** 🔴
- **File:** `src/KArtSell.Host/Infrastructure/KisConnectionPool.cs` (new)
- **Contract:**
  - 3-5 concurrent connections
  - OAuth2 token refresh (55-min interval)
  - Priority queue (BUY > SELL > CANCEL)
- **AGENTS.md:**
  - Complexity: Connection lifecycle management (async, careful)
  - Safety: Token refresh idempotency + fallback
  - Pattern: Object pool + priority queue

---

### **Tier 4: Phase 3 (2+ weeks, ~6-7 hours)**
**Goal:** Production-grade Rate Limiting + Circuit Breaker + Observability

**Items (in dependency order):**

#### **4.1 Central Rate Limiter (3 hours)** 🔴
- **File:** `src/KArtSell.Host/Infrastructure/RateLimiterService.cs` (new)
- **Contract:**
  - Token bucket pattern (all APIs)
  - Per-API quota tracking
  - Fairness guarantee
- **AGENTS.md:**
  - Complexity: Token bucket state management (careful)
  - Safety: Atomic operations (no partial success)
  - Pattern: Middleware + IDistributedCache

#### **4.2 Circuit Breaker Pattern (1 hour)** 🟡
- **Integration:** Polly library
- **Policy:**
  - 3x 429 errors → 5-min breaker open
  - Auto-recovery (time-based)
- **Error classification:** transient/permanent/dq/business-hold

#### **4.3 Gate 5 Observability Dashboard (2 hours)** 🟡
- **Endpoint:** GET /api/observability/metrics (already exists)
- **Metrics:**
  - Batch SLA (job completion times)
  - Data Quality (quarantined items)
  - Duplicate Detection (outbox warnings)
  - Reconciliation Breaks (state mismatches)
  - Model Drift (OOS performance)

## 🎯 Next Action

**User must unblock Gate 3 by running:**
```bash
# Terminal 1
ssh -L 5432:127.0.0.1:5432 kjh2064@178.104.200.7

# Terminal 2
cd D:\JobRoomz\KArtSell.Aegis
dotnet run --project src/KArtSell.Host -c Release
```

**I will then:**
1. Execute Gate 3 shadow run validation
2. Generate GATE_3_EVIDENCE.md
3. Start Phase 2 work (OpenDart + KIS + Gate 4)
4. Track progress via loop (30-sec status checks)

**Exit criterion:** All 5 gates PASS → Production readiness confirmed
