+# Reference feature ownership and removal
+
+이 모듈은 제품 도메인이 아니라 새 기능의 수직 경계를 검증하는 제거 가능한
+reference implementation이다.
+
+## 소유 경계
+
+- `domain`: 외부 DTO와 React를 모르는 불변 model
+- `application`: UI가 호출하는 list/create input과 gateway 계약
+- `adapters`: HTTP executor를 gateway로 투영하는 outbound adapter
+- `contracts`: route/API/query contribution, Zod DTO와 request schema, mapper
+- `presentation`: route input을 query/mutation controller로 연결하는 inbound
+  adapter와 page
+
+generic application은 `features.get(featureId)` catalog만 제공한다. feature hook이
+자신의 input shape를 확인하며 page는 HTTP client, storage, auth owner, output
+port나 TanStack API를 직접 import하지 않는다.
+
+## 설치 지점
+
+- 직렬화 계약: `src/features/installed-feature-contracts.js`
+- component/codec: `src/features/installed-feature-runtimes.tsx`
+- bootstrap input 조립: `src/features/installed-feature-adapters.ts`
+
+새 기능도 이 세 지점에 contribution을 합성하되 feature ID를 generic application,
+router나 HTTP client에 하드코딩하지 않는다.
+
+## 검증과 제거
+
+```sh
+corepack pnpm test:reference-feature
+corepack pnpm test:sample-removal
+```
+
+첫 명령은 URL filter와 query key/HTTP request의 동일성, schema/mapper, 모든
+query/mutation 상태와 production composition을 검증한다. 두 번째 명령은 임시
+복제본에서 이 source/test 디렉터리를 제거하고 installed catalog를 빈 목록으로
+재생성한 뒤 typecheck, architecture, registry, unit/integration, home smoke,
+production build와 fixture ID 잔여 0개를 검사한다.
