+# VD-03: React Router Data Mode와 서버 상태 소유권
+
+- 상태: Accepted
+- 결정일: 2026-07-26
+- 적용 브랜치: `feature-frontend-routing-release-recovery-runtime`
+
+## 배경
+
+기존 라우터는 `BrowserRouter`와 수동 JSX route 목록을 사용했다. 직렬화 가능한
+route registry에 params/search schema, loading/error surface, access, title,
+navigation과 chunk ID가 있었지만 실행 route tree와 독립적이어서 선언과 행동이
+어긋날 수 있었다.
+
+이 저장소는 client-only SPA이며 서버 상태는 application input과 TanStack Query가
+소유한다. Framework Mode의 loader/action 중심 데이터 소유권이나 SSR을 도입하지
+않으면서 route object, 오류 경계와 navigation lifecycle은 중앙에서 조립할
+필요가 있다.
+
+## 결정
+
+1. 고정된 React Router `7.18.1`의 `createBrowserRouter`와 `RouterProvider`를
+   사용하는 Data Mode를 기본값으로 채택한다.
+2. 직렬화 가능한 route contract와 React component/codec runtime map을 분리한다.
+3. 모든 executable route object와 navigation은 registry에서 생성한다. JSX에서
+   route 목록을 다시 열거하지 않는다.
+4. params/search는 route 경계의 Zod codec으로 parse하고 같은 codec으로 canonical
+   URL을 생성한다.
+5. loader/action은 같은 서버 데이터를 직접 다시 요청하지 않는다. 필요하면
+   application input 또는 query adapter 한 경로를 호출한다.
+6. 서버 상태, retry, cache와 mutation lifecycle은 application input과 TanStack
+   Query가 계속 소유한다.
+7. lazy chunk rejection만 release recovery input으로 보내며 일반 render error는
+   route/feature boundary가 소유한다.
+8. Framework Mode, SSR, static generation과 router version upgrade는 별도
+   dependency/architecture 브랜치에서 결정한다.
+
+## 검증
+
+- route contract/runtime map의 누락과 orphan은 TypeScript negative fixture와
+  registry gate가 모두 거절한다.
+- duplicate ID/path, unknown codec/surface/chunk와 참조 불일치를 negative registry
+  fixture로 검증한다.
+- params/search parse/build round-trip, canonical redirect, 최대 redirect hop,
+  access rejection, title/focus와 boundary reset을 unit/component test로 검증한다.
+- Vite dynamic entry와 release route chunk map, runtime config JSON Schema를
+  build/release 검증기가 확인한다.
+- chunk failure는 no-store manifest refetch 후 build/release 쌍마다 한 번만
+  reload하며 offline, malformed manifest와 storage 실패는 fail-closed한다.
+
+## 결과와 rollback
+
+Data Router는 navigation lifecycle의 조립 경계이며 서버 데이터 계층이 아니다.
+이 구분을 지키면 React Router를 교체해도 application input과 output port는
+유지된다.
+
+rollback은 RP-04 merge를 되돌려 이전 수동 router와 generic route failure
+surface로 복구한다. URL shape와 application API는 유지하고, 이미 배포된 asset
+cache의 purge는 저장소 rollback 범위에 포함하지 않는다.

+# VD-04: Native form controller와 local facade
+
+- 상태: Accepted
+- 결정일: 2026-07-26
+- 적용 브랜치: `feature-frontend-form-page-platform`
+
+## 배경
+
+플랫폼에는 Zod가 이미 설치돼 있지만 form state, field error, dirty navigation과
+page template 계약은 없었다. React Hook Form과 resolver를 바로 추가하면
+dependency와 lockfile이 바뀌고, 현재 reference form에 필요하지 않은 복합 비동기
+field orchestration까지 플랫폼 기본값으로 고정하게 된다.
+
+## 결정
+
+1. RP-06은 React native form event와 controlled value를 사용하는 local
+   `useAppForm` facade를 기본 엔진으로 채택한다.
+2. Zod presentation schema, application command mapper와 domain invariant는 서로
+   다른 소유물로 유지한다.
+3. page와 feature는 `useAppForm`, `Form`, `FormField`, `ErrorSummary`,
+   `mapValidationFailureToFields`, `useDirtyNavigationGuard`만 사용한다.
+4. 422 details는 승인된 `path`와 `code`만 HTTP 경계에서 투영한다. backend
+   message와 알 수 없는 field는 field에 전달하지 않고 안전한 form-level
+   error로 이동한다.
+5. 409 conflict는 validation으로 바꾸지 않으며 입력과 dirty 상태를 보존한다.
+6. pending submit은 동일 controller에서 한 번만 실행하고 success/reset 이후
+   dirty 상태를 해제한다.
+7. `StandardPage`, `CollectionPage`, `DetailPage`, `FormPage`, `StatusPage`는
+   layout과 state slot만 소유하며 application/query/HTTP를 import하지 않는다.
+
+## React Hook Form 도입 조건
+
+다음 중 하나가 실제 제품 요구로 확인되면 local facade 내부 adapter로
+React Hook Form과 Zod resolver를 평가한다.
+
+- 동적 field array와 중첩 object를 함께 다루는 복합 form
+- field 단위 비동기 validation 취소와 의존 validation
+- 수백 개 field의 render isolation이 측정 가능한 병목인 경우
+- uncontrolled input 또는 vendor extension이 필요한 경우
+
+도입하더라도 이 문서의 public API와 component/application tests를 유지해야
+한다. vendor package를 feature/page에서 직접 import하는 것은 허용하지 않는다.
+
+## 검증과 rollback
+
+- client validation, transform/default, 422 allowlist, conflict, duplicate submit,
+  reset, dirty guard와 focus를 component test로 검증한다.
+- template 최소/전체 slot과 async/status variation을 component test로 검증한다.
+- architecture gate가 template의 application/HTTP/query vendor import를
+  거절한다.
+- secret-like input이 URL, storage, diagnostics에 복제되지 않는지 검증한다.
+
+rollback 시 reference page는 이전 직접 form/layout으로 돌아갈 수 있다.
+application input과 outbound gateway 계약은 유지되며, form facade와 template
+commit은 독립적으로 되돌릴 수 있다.

+# 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/get/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/form controller로 연결하는 inbound
+  adapter, 독립 form schema/command mapper와 list/detail/form/status 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/form 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 source/built fixture ID 잔여 0개를 검사한다.
