-# ca-skeleton — Clean Architecture Spring Boot 템플릿
+# Tech Log Backend
+
+Initialized from `clean-architecture-backend-template` revision
+`0a6dd0e419620683de48f69b5c6d22d9964b6f44` as a tracked snapshot. Template
+updates are applied explicitly and recorded in `template.lock.json`.
 
 ca-skeleton은 Java 21, Spring Boot 4.0.0, Gradle 멀티모듈 기반의 Clean Architecture 백엔드 템플릿입니다. fork해서 도메인·패키지·엔티티·유스케이스만 교체하면 새 서비스를 시작할 수 있고, 모듈 경계와 의존 방향은 그대로 유지합니다. 기본 패키지는 `dev.caskeleton`이며, 예시 도메인은 production 모듈이 아니라 `sample-portfolio` 모듈(WorkLog 작업 기록 게시판)에 격리합니다.
