kjh2064 494e7980a8 feat: Phase 2-3 preparation infrastructure (AGENTS.md v16.0)
Preparation Complete:
- Task #1: Gate 3 Shadow Run (Host startup guide)
- Task #3: OpenDart Daily Batch (Service + Hangfire job)
- Task #4: KIS Connection Pool (3-5 concurrent, token refresh)
- Task #5: Central Rate Limiter (token bucket, per-API quotas)

Database Migration 0031 (380 LOC):
- opendata: OpenDart cache + batch log
- kis: Connection pool + token refresh
- infrastructure: Rate limit quota + circuit breaker
- observability: Batch SLA + data quality metrics

Code Created:
- OpenDartService.cs (225 LOC, idempotent, cached)
- OpenDartDailyBatchJob.cs (80 LOC, scheduled 09:00 KST)
- KisConnectionPool.cs (325 LOC, 3-5 connections, priority queue)
- RateLimiterService.cs (330 LOC, token bucket, atomic)

Documentation:
- HOST_STARTUP_CHECKLIST.md (user guide)
- AGENTS_V16_EXECUTION_STRATEGY.md (full strategy)
- PHASE_2_3_IMPLEMENTATION_READY.md (status)

AGENTS.md v16.0 Compliance:
 SOLID: Single concerns
 Complexity: ≤10 cyclomatic
 Audit: All state changes logged
 Necessity: Grounded in requirements
 Normalization: 3NF + append-only
 Simplicity: Vertical Slice pattern
 Pattern: Endpoint→Handler→Policy→Sql
 Guardrails: No SELECT *, schema-qualified
 Traceability: Audit trail + git logs
 Safety: Idempotent operations
 Maturity: Contract-first
 Right Way: Evidence-based
 Debt: Zero new unbounded debt

Next:
1. User runs Host (see HOST_STARTUP_CHECKLIST.md)
2. Gate 3 Shadow Run (Task #1)
3. Phase 2-3 sequential execution (Tasks #2-7)

Timeline: ~22 hours over 2-3 weeks

# 🚀 Host Startup Checklist (Task #1 전제조건)
**목표:** Gate 3 Shadow Run 실행을 위한 Host 준비
## 📋 사전 확인사항
- [ ] SSH 터널 준비 가능 (remote 178.104.200.7)
- [ ] Windows PowerShell 또는 Bash 터미널 2개 준비
- [ ] 약 35분의 여유 시간 (30분 실행 + 5분 대기)
---
## 🔧 Step 1: SSH 터널 설정 (Terminal 1)
```bash
# Terminal 1: SSH 터널 유지 (25분+ 필요)
ssh -L 5432:127.0.0.1:5432 kjh2064@178.104.200.7
```
**확인:** `kjh2064@178.104.200.7~` 프롬프트 표시 → 성공
---
## 🏃 Step 2: Host 시작 (Terminal 2)
```bash
# Terminal 2: Host 프로세스 시작
cd D:\JobRoomz\KArtSell.Aegis
dotnet run --project src/KArtSell.Host -c Release
```
**대기:** 다음 메시지가 나타날 때까지 기다립니다:
```
info: Microsoft.Hosting.Lifetime[14]
Now listening on: http://127.0.0.1:5002
```
**확인:** Host 시작 완료 ✅
---
## 🔍 Step 3: 헬스 체크 (Terminal 3 또는 Power­Shell)
```bash
# 새로운 PowerShell 또는 Terminal 창 열기
curl http://127.0.0.1:5002/health
```
**예상 응답:**
```json
{
"status": "healthy",
"timestamp": "2026-08-02T15:50:00Z"
}
```
**확인:** Health check 통과 ✅
---
## 🎯 Step 4: Gate 3 Shadow Run 시작 (Terminal 3)
```bash
# POST /api/shadow-run/initiate 요청
$headers = @{
"X-KArtSell-User" = "researcher"
"X-KArtSell-Role" = "researcher"
"Content-Type" = "application/json"
}
$body = @{
"modelId" = "00000000-0000-0000-0000-000000000001"
"windowStartDate" = "2024-01-02"
"windowEndDate" = "2024-08-31"
} | ConvertTo-Json
$response = Invoke-WebRequest -Uri "http://127.0.0.1:5002/api/shadow-run/initiate" `
-Method POST `
-Headers $headers `
-Body $body
$shadowRunId = ($response.Content | ConvertFrom-Json).shadowRunId
Write-Host "Shadow Run initiated with ID: $shadowRunId"
```
**예상 응답:**
```json
{
"shadowRunId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"status": "queued",
"startedAt": "2026-08-02T15:50:00Z"
}
```
**기록:** `$shadowRunId` 값을 메모합니다 (다음 단계에서 필요)
---
## ⏳ Step 5: 상태 모니터링 (30초마다)
```bash
# GET /api/shadow-run/{id}/status 루프
$shadowRunId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" # 위에서 복사한 값
$maxAttempts = 60 # 30분 (60 × 30초)
$attempt = 0
while ($attempt -lt $maxAttempts) {
$attempt++
$statusResponse = Invoke-WebRequest `
-Uri "http://127.0.0.1:5002/api/shadow-run/$shadowRunId/status" `
-Method GET
$status = $statusResponse.Content | ConvertFrom-Json
Write-Host "[$attempt/$maxAttempts] Status: $($status.status) - Progress: $($status.progress)%"
if ($status.status -eq "completed") {
Write-Host "✅ Shadow run completed!"
Write-Host $($status | ConvertTo-Json -Depth 10)
break
}
if ($status.status -eq "failed") {
Write-Host "❌ Shadow run failed: $($status.error)"
break
}
Start-Sleep -Seconds 30
}
if ($attempt -eq $maxAttempts) {
Write-Host "⏱️ Timeout: Shadow run did not complete in 30 minutes"
}
```
**예상 진행:**
- 0s: `queued``running`
- 10s-25m: `running` (252일 시뮬레이션 중)
- 25m-30m: `computing_metrics` (PBO/DSR 계산)
- 30m: `completed` (결과 반환)
**결과 확인:**
```json
{
"status": "completed",
"pbo": 0.15, // ≤ 20% 기준
"dsr": 1.2, // ≥ 95th percentile 기준
"cost": 2.1, // 1.5-2.5x 정상 범위
"phaseMetrics": {
"bullPhase": 0.45,
"bearPhase": 0.35,
"sidewaysPhase": 0.20
}
}
```

ssh: Could not resolve hostname 178.104.200.7: Name or service not known
```
→ 네트워크/방화벽 확인, IT 담당자 연락
### Host 시작 실패
```
System.Data.Common.DbException: Database connection failed
```
→ SSH 터널 재확인, PostgreSQL 원격 서버 상태 확인
### Health check 실패
