Branch Naming Convention

Branch Rules

1. Base Branch: develop (NOT main)
2. Feature/Refactor/Fix: Branch from develop, merge back to develop
3. Hotfix: Branch from main, merge to both main and develop
4. Release: Branch from develop, merge to main after QA

⚠️ CRITICAL: PR은 반드시 develop 브랜치를 base로 생성해야 합니다.

• gh pr create --base develop (NOT --base main)
• main으로 잘못 머지하면 main → develop PR을 추가로 생성해야 합니다.

Commit Convention (Conventional Commits)

CI/CD Integration

GitOps 플로우

ArgoCD가 develop 브랜치를 바라봄 (Staging 아님, Dev 환경 직접 배포)

PR → develop 머지 → ArgoCD auto-sync → Dev 클러스터 반영

Branches Triggering CI

Quality Gates

• Linting (ruff, black)
• Type checking (mypy)
• Unit tests (pytest)
• Security scan (SonarCloud)
