+# SafeCrowd GitHub Project
+
+## 개요
+- Project: `SafeCrowd Implementation`
+- URL: `https://github.com/users/learncold/projects/1`
+- Repository: `learncold/cpp-ecs-engine`
+- 관리 방식:
+  - Epic과 Task를 모두 issue로 관리한다.
+  - Epic-Task 관계는 GitHub native `Parent issue` / `sub-issue`를 사용한다.
+  - 선행 작업 관계는 GitHub native issue dependency `blocked by`를 사용한다.
+
+## 현재 필드
+- `Title`
+- `Status`
+  - `In Progress`
+  - `Done`
+- `Area`
+  - `⚙️Engine`

+## 메모
+- `Docs`, `Chore`, `Analysis`는 `Lightweight Task` form으로 가볍게 등록한다.
+- `Engine`, `Domain`, `Application`, `Build`는 `Implementation Task` form으로 범위와 검증 계획까지 남긴다.
+- 세부 작업명, 부모-자식 관계, dependency는 GitHub Project와 issue 자체를 기준으로 관리한다.
+- 2026-03-20 기준 현재 `In Progress` 상태인 작업은 `#6 T-001`이다.
