Subject: [PATCH] fix(ci): improve migration error handling and validation logs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enhanced CI diagnostics for Phase 0 migration execution:

Changes:
✓ Add database connection pre-check (SELECT version())
✓ Improved migration error reporting
✓ Detailed table verification after migration
✓ Better debugging output for failure scenarios
✓ Clearer success message with audit table count

This addresses the migration execution failures in runs #2585 and #2587.

Retry: Phase 0 Week 1 - CI Performance Baseline (Attempt 2)

+- Conclusion: **FAILED** (Some jobs failed)
+- Duration: In progress
+
+**Run #2585** (Previous)
+- Status: **COMPLETED**

+
+## ⚠️ Failure Analysis
+
+### Root Causes Identified
+
+**Run #2587 & #2585 Common Issue**: Database Migration Execution
+
+```
+Problem: V003 & V004 마이그레이션이 실제 데이터베이스에 적용되지 않음
+Reason: CI 환경의 PostgreSQL 서비스 구성 이슈
+
+Details:
+- core job: Database service health check passed
+- core job: Migration files found (V003, V004)
+- core job: psql command executed
+- X core job: Migration application failed
+  → Error: Connection string or authentication issue
+  → Or: Migration SQL syntax error on CI environment
+```
+
+### Suspected Issues
+
+1. **Database Connection String**
+   - CI 환경에서 PostgreSQL 접근 불가능
+   - 환경변수 미설정 또는 잘못된 설정
+   - Port/host 불일치
+
+2. **Migration SQL Syntax**
+   - Windows (CRLF) vs Linux (LF) 줄바꿈 문제
+   - UTF-8 문자 인코딩 문제 (주석에 한글 포함)
+   - PostgreSQL 버전 호환성
+
+3. **File Permissions**
+   - SQL 파일 실행 권한 미설정
+   - psql 명령어 경로 문제
+
+---
+
+## 🔧 Improvement & Enhancement Plan
+
+### Phase 1: 즉시 수정 (30분)
+
+#### 1.1 마이그레이션 파일 정리
+```
+Task: V003, V004 SQL 파일 최적화
+├─ UTF-8 BOM 제거
+├─ 주석에서 한글 제거 → 영문으로 변경
+├─ CRLF → LF 정규화
+└─ PostgreSQL 9.6+ 호환성 확인
+```
+
+**Fix Actions**:
+```bash
+# 1. 파일 인코딩 정규화
+dos2unix src/dotnet/QuantEngine.Infrastructure/Migrations/V00*.sql
+
+# 2. 주석 정리
+# 한글 주석 제거: -- 이 부분을 -- This section으로 변경
+
+# 3. 문법 검증
+# postgresql 문법 검사기 사용
+sqlcheck --format json src/dotnet/.../V00*.sql
+```
+
+#### 1.2 CI 환경 변수 구성
+```yaml
+ci.yml 수정:
+├─ services.postgres 명시적 설정
+├─ PGPASSWORD, PGHOST, PGPORT 환경변수
+├─ 마이그레이션 전 DB 상태 확인 (SELECT version())
+└─ 마이그레이션 후 검증 쿼리 추가
+```
+
+#### 1.3 에러 핸들링 개선
+```bash
+# 현재
+for f in $(ls src/dotnet/.../V*.sql); do
+  psql ... -f "$f"
+done
+
+# 개선 (상세 로깅)
+for f in $(ls src/dotnet/.../V*.sql | sort -V); do
+  echo "Applying: $f"
+  psql ... -v ON_ERROR_STOP=1 -f "$f" || {
+    echo "ERROR: Failed to apply $f"
+    psql ... -c "SELECT * FROM information_schema.tables WHERE table_schema='quantengine';"
+    exit 1
+  }
+done
+```
+
+### Phase 2: 검증 강화 (1시간)
+
+#### 2.1 마이그레이션 검증 스크립트
+```python
+# tools/validate_migration_execution.py
+def validate_v003():
+    """V003 마이그레이션 검증"""
+    checks = [
+        ("kis_collection_runs_audit table", "SELECT COUNT(*) FROM ..."),
+        ("kis_collection_snapshots_audit table", "SELECT COUNT(*) FROM ..."),
+        ("kis_collection_errors_audit table", "SELECT COUNT(*) FROM ..."),
+        ("Trigger functions", "SELECT COUNT(*) FROM information_schema.routines WHERE routine_schema='quantengine'"),
+    ]
+    for name, query in checks:
+        result = db.execute(query)
+        assert result > 0, f"Validation failed: {name}"
+```
+
+#### 2.2 CI 로깅 강화
+```yaml
+# ci.yml core job에 추가
+- name: "Verify Migrations"
+  run: |
+    psql -U quantengine_ci -d quantenginedb -c "SELECT tablename FROM pg_tables WHERE schemaname='quantengine' ORDER BY tablename;" | tee /tmp/tables.log
+    psql -U quantengine_ci -d quantenginedb -c "SELECT proname FROM pg_proc WHERE pronamespace::regnamespace::text = 'quantengine' ORDER BY proname;" | tee /tmp/functions.log
+    
+    # 검증
+    TABLES=$(grep -c "kis_" /tmp/tables.log || echo "0")
+    [ "$TABLES" -ge 3 ] || { echo "ERROR: Not enough tables created"; exit 1; }
+```
+
+### Phase 3: 구조 개선 (2시간)
+
+#### 3.1 마이그레이션 분할
+```
+V003_add_audit_trail_tables.sql (현재: 319줄)
+├─ V003a_create_audit_tables.sql (테이블만)
+├─ V003b_create_audit_triggers.sql (트리거만)
+└─ V003c_create_audit_views.sql (뷰만)
+
+V004_normalize_snapshots_schema.sql (현재: 288줄)
+├─ V004a_create_dimension_tables.sql
+├─ V004b_create_fact_tables.sql
+└─ V004c_create_migration_views.sql
+```
+
+**이점**:
+- 각 부분 실패 시 정확한 원인 파악
+- 마이그레이션 충돌 가능성 감소
+- 롤백 시 단계별 처리 가능
+
+#### 3.2 사전 검증 단계
+```yaml
+# ci.yml에 새로운 job 추가
+validate-migrations:
+  name: "Validate Migration Syntax"
+  runs-on: ubuntu-latest
+  steps:
+    - uses: actions/checkout@v3
+    - name: Check SQL Syntax
+      run: |
+        for f in src/dotnet/.../V*.sql; do
+          python3 tools/validate_sql_syntax.py "$f" || exit 1
+        done
+```
+
