+# Live Infrastructure
+
+실제로 plan/apply하는 root를 둡니다. leaf 디렉터리 하나가 독립적인 state,
+locking, 권한과 실패 범위입니다.

+소규모 예:

+```text
+live/
+└── dev/

+경로 깊이보다 leaf의 실행 계약이 중요합니다. 자동화는 특정 depth를 가정하지
+말고 IaC root marker를 기준으로 대상을 찾습니다.
+
+## 규칙
+
+- 각 root는 remote backend와 locking을 사용합니다.
+- production과 non-production state/credential을 분리합니다.
+- 민감하지 않은 입력만 커밋하며 secret 입력은 runtime에 주입합니다.
+- 다른 환경 경로를 상대 import하지 않습니다.
+- provider, module과 component version을 고정합니다.
+- output consumer와 파괴 영향 범위를 README에 기록합니다.

+- State: `vault-workloads`
+- Backend example: `backend.s3.hcl.example`
+- Owner: delegated workload automation

+정확한 workload ACL, Kubernetes auth role와 Project Auth Transit key를
+소유합니다. `policies/`의 ACL은 wildcard 없이 workload가 실제 사용하는
+경로만 허용합니다.
+
+Foundation이 만든 short-lived identity로 실행하며, 이 state는 자기 실행
