-# clean-architecture-frontend-template
+# Clean Architecture Frontend Template

+A React/Vite reference implementation where architecture boundaries,
+integration behavior, release coherence, accessibility, performance, and
+operations are executable contracts rather than conventions.
+
+## Start locally
+
+Requirements: Node 24.11 or newer and Corepack. The repository pins pnpm in
+`package.json`.
+
+```bash
+corepack pnpm install --frozen-lockfile
+corepack pnpm dev
+```
+
+Runtime-public settings live in `public/config.json` and are validated before
+the product tree mounts. Client secrets are forbidden.
+
+## Included starter experience
+
+The default build mounts a domain-neutral application shell with a header,
+responsive sidebar, route focus management, session integration status, and a
+persistent `system` / `light` / `dark` theme selector.
+
+| Route | Purpose |
+| --- | --- |
+| `/` | implementation readiness and starter links |
+| `/examples/ui` | buttons, fields, cards, alerts, badges, modal, and tokens |
+| `/examples/states` | loading, refresh, empty, error, auth, forbidden, and not-found states |
+| `/examples/auth` | reactive external-auth integration seam |
+| `/sample/resources` | protected, domain-neutral integration route |
+
+`AUTH_MODE=demo` is credential-free and accepted only in local/development
+environments. Deployments use `AUTH_MODE=external` and provide the opaque auth
+owner described in
+[`docs/architecture/starter-experience.md`](docs/architecture/starter-experience.md).
+The client route policy is user experience only; server authorization remains
+authoritative.
+
+## Architecture
+
+Dependencies point inward:
+
+```text
+presentation -> application -> domain
+adapters -----^
+bootstrap composes concrete adapters
+contracts own cross-cutting registries
+```
+
+See `docs/architecture/overview.md`, `docs/architecture/layers.md`, and
+`docs/architecture/starter-experience.md`. The removable sample slice is under
+`src/sample/contract-fixture`; product code is not allowed to import it. The
+visible starter routes do not depend on that fixture and continue to build
+after it is removed.
+
+### Platform capability review
+
+The starter shell is implemented, but the repository review also records the
+remaining work required before feature teams can use every declared contract
+through one end-to-end application path:
+
+- [platform capability review](docs/architecture/frontend-platform-capability-review.md)
+- [ports, adapters, and feature boundaries](docs/architecture/frontend-ports-adapters-and-boundaries.md)
+- [TypeScript, state ownership, and data flow](docs/architecture/typescript-state-and-data-flow.md)
+- [routing, page templates, and reusable patterns](docs/architecture/routing-pages-and-patterns.md)
+- [design-system platform](docs/styling/design-system-platform.md)
+- [frontend platform testing strategy](docs/testing/frontend-platform-testing-strategy.md)
+- [implementation roadmap](docs/architecture/frontend-platform-implementation-roadmap.md)
+
+These documents distinguish repository defaults from opt-in adapters and
+project-owned integrations. They are target designs and review findings; a
+capability is not treated as implemented until its branch acceptance criteria
+and executable gates pass.
+
+## Verification
+
+Common local checks:
+
+```bash
+corepack pnpm lint
+corepack pnpm check:types
+corepack pnpm check:types:app
+corepack pnpm check:types:node
+corepack pnpm check:types:test
+corepack pnpm check:architecture
+corepack pnpm test:all
+corepack pnpm test:e2e
+corepack pnpm test:a11y
+corepack pnpm build
+corepack pnpm check:bundle
+corepack pnpm test:performance
+corepack pnpm verify:compatibility
+corepack pnpm verify:release
+corepack pnpm check:registries
+corepack pnpm drill:runbooks
+corepack pnpm check:ci
+```
+
+`check:types`는 source, Node scripts/config와 tests를 분리된 TypeScript
+project로 모두 검사한다. type/architecture/security/registry의 invalid
+fixture는 `config/ci/gates.json`에서 “실패해야 통과”하는 negative gate로
+실행된다. 도구 호환성 결정은
+[VD-01](docs/architecture/decisions/VD-01-typescript-lint-tooling.md)에 기록돼
+있다.
+
+Install the pinned Playwright browser engines before the first cross-browser
+run:
+
+```bash
+corepack pnpm exec playwright install --with-deps chromium firefox webkit
+```
+
+Two gates intentionally need external evidence:
+
+- `review:a11y-manual` needs a signed human keyboard/focus/screen-reader review
+  for all six registered routes.
+- `collect:web-vitals-evidence` stays `FAIL_UNVERIFIED` until a reviewed minimum
+  eligible-sample threshold and 28 days of production data exist.
+
+Live release verification additionally requires `HOSTING_BASE_URL`.
+
+## CI and evidence
+
+The 26-gate registry is `config/ci/gates.json`; the Gitea workflow is
+`.gitea/workflows/quality-gates.yml`. It follows:
+
+```text
+MERGE_READY -> RELEASE_READY -> PROD_PROMOTION_READY -> FIELD_SLO_READY
+```
+
+`DOCUMENTATION_READY` is independent. No gate is downgraded to a warning.
+Machine-readable evidence is written below `artifacts/`; generated evidence is
+ignored by Git while `.gitkeep` files preserve the taxonomy.
+
+Operational details are in `docs/operations/`, with incident procedures in
+`docs/runbooks/`.

+# Manual accessibility review checklist
+
+Automated axe checks do not establish WCAG conformance. A human reviewer must
+review all six route records in `artifacts/tests/a11y-manual/` against one
+release candidate and sign them. The required scope is derived from the route
+registry: `APP_HOME`, `EXAMPLES_UI`, `EXAMPLES_STATES`, `EXAMPLES_AUTH`,
+`REFERENCE_RESOURCE_LIST`, and `NOT_FOUND`. Copy the template fields exactly; the
+gate rejects blank identity/timestamp/signature fields, pending verdicts,
+mismatched release IDs, or missing routes.
+
+Allowed item verdicts:
+
+- `pass`
+- `not-applicable (<specific reason>)`
+
+Required record:
+
+```text
+Status: reviewed
+Route ID: APP_HOME
+Release ID: <immutable release ID>
+Reviewer: <human reviewer identity>
+Reviewed at: <RFC 3339 timestamp>
+Signature: <reviewer identity or approved signature reference>
+Attestation: accepted
+M1 Keyboard: pass
+M2 Visible focus: pass
+M3 Route focus: pass
+M4 Modal focus: not-applicable (no modal on this route)
+M5 Error association: not-applicable (no form error on this route)
+M6 Color signal: pass
+M7 Reduced motion: pass
+Screen reader: pass
+Notes: <observations and linked defect IDs>
+```
+
+The reviewer must verify:
+
+- M1: every action works without a pointing device
+- M2: every focused element has a visible indicator
+- M3: route transitions move focus to a deterministic target
+- M4: modal focus is trapped and restored, when a modal exists
+- M5: errors are programmatically associated with their controls, when present
+- M6: state never relies on color alone
+- M7: non-essential motion is suppressed with reduced-motion preference
+- Screen reader: headings, live regions, errors, and actions are announced once
+
+`EXAMPLES_UI` requires real M4 modal and M5 field-error review; those items must
+not be marked not-applicable on that route. Passing automated evidence means
+only that tested pages had no critical or serious axe findings under the
+recorded Chromium, Firefox, and WebKit runs.

+# VD-01: TypeScript 7과 ESLint 10의 점진적 전환 도구
+
+- 상태: Accepted
+- 결정일: 2026-07-26
+- 적용 브랜치: `feature-frontend-typescript-tooling-foundation`
+
+## 배경
+
+저장소는 TypeScript `7.0.2`와 ESLint `10.8.0`을 고정하고 있다. 첫 전환
+브랜치는 compiler를 변경하거나 production source를 일괄 변환하지 않고
+JS/JSX/TS/TSX가 같은 품질 게이트를 통과하게 해야 한다.
+
+결정 시점의 package peer contract는 다음과 같다.
+
+- `typescript-eslint@8.65.0`과 canary는 TypeScript `<6.1.0`을 요구한다.
+- `eslint-plugin-jsx-a11y@6.10.2`는 ESLint `<=9`를 요구한다.
+- `eslint-plugin-react-hooks@7.1.1`은 ESLint 10을 지원한다.
+- Babel 8 ESLint parser는 ESLint 10을 지원하고 Node `>=24.11.0`을 요구한다.
+
+호환되지 않는 peer dependency를 강제 설치하면 lockfile 검증은 통과하더라도
+지원되지 않는 parser와 rule 조합을 플랫폼 계약으로 만들게 된다.
+
+## 결정
+
+1. TypeScript `7.0.2`와 ESLint `10.8.0`을 유지한다.
+2. TypeScript/TSX의 ESLint syntax parsing에는
+   `@babel/eslint-parser`와 TypeScript/JSX syntax plugin을 사용한다.
+3. TypeScript의 이름 해석, unused 진단과 type semantics는 `tsc`가 소유한다.
+   Babel parser가 TypeScript scope manager를 제공하지 않으므로 TS 파일의
+   core `no-undef`와 `no-unused-vars`는 끄고 분리된 app/node/test TypeScript
+   project를 필수 게이트로 실행한다.
+4. React Hook 규칙은 호환되는 `eslint-plugin-react-hooks`로 즉시 적용한다.
+5. JSX 접근성은 현재의 semantic component contract, Testing Library,
+   axe 기반 cross-browser gate와 수동 검토 계약이 계속 담당한다. 호환되지 않는
+   `eslint-plugin-jsx-a11y`는 설치하지 않는다.
+6. Babel 8의 지원 범위에 맞춰 Node engine 하한을 `24.11.0`으로 명시한다.
+7. production source의 대량 rename은 이 결정에 포함하지 않는다.
+
+## 검증
+
+- `check:types`는 app, Node scripts/config, tests project를 모두 검사한다.
+- JS invalid-call, TS invalid port, TS discriminated-union fixture는 실패해야 한다.
+- ESLint와 dependency-cruiser는 TS/TSX architecture fixture를 검사한다.

+
+- 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.

+
+Data Router는 navigation lifecycle의 조립 경계이며 서버 데이터 계층이 아니다.
+이 구분을 지키면 React Router를 교체해도 application input과 output port는
+유지된다.

+# 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.

+
+- 상태: Accepted
+- 결정일: 2026-07-26
+- 적용 브랜치: `feature-frontend-design-system-platform`
+- 재검토: native 계약으로 충족할 수 없는 widget 요구가 확인될 때
+
+## 배경
+
+앱 셸과 공통 UI는 문자 glyph, raw button/select와 페이지별 focus 처리를
+사용했다. 아이콘 공급자와 복합 interaction을 제품 코드에 직접 노출하면 번들,
+접근성, vendor type과 교체 비용이 모든 feature로 전파된다. 반대로 실제 요구가
+없는 두 개의 headless vendor를 기본 설치하면 skeleton 소비자가 제거해야 할
+의존성과 중복 interaction 모델이 생긴다.
+
+## 결정
+
+1. 아이콘 공급자는 lockfile 최소 게시 유예를 통과한 `lucide-react@1.25.0`으로
+   고정한다.
+2. `lucide-react`의 static named import는
+   `design-system/icons/vendors/lucide.tsx` 한 파일에서만 허용한다.
+3. public API는 `MenuIcon`, `CloseIcon`, `WarningIcon` 같은 의미 이름만
+   노출한다. vendor component type, icon name, stroke API와 dynamic icon
+   registry는 노출하지 않는다.
+4. 장식 아이콘은 accessibility tree에서 제외한다. 정보를 단독 전달하는
+   아이콘은 `label`, icon-only action은 필수 `accessibleName`을 사용한다.
+5. 현재 복합 control은 native `dialog`, form control, `details`와 local
+   TypeScript state model로 구현한다. Menu는 roving focus/typeahead/Escape,
+   Tabs는 manual/automatic activation, Drawer는 modal/background
+   비활성화/focus restore 계약을 가진다.
+6. React Aria와 Radix는 기본 dependency로 추가하지 않는다. native platform이
+   collision, nested overlay, virtualized collection 또는 복합 select 요구를
+   충족하지 못한다는 재현 가능한 요구가 생길 때 prototype과 ADR로 다시
+   평가한다.
+7. Storybook과 pinned visual baseline은 VD-08/RP-10에서 도입한다. RP-07의
+   runtime gallery와 browser interaction test는 해당 workshop을 대체한다고
+   주장하지 않는다.
+
+## 경계와 검증
+
+- 제품 코드는 `presentation/design-system/index`만 import한다.
+- design-system 검사기는 direct icon/headless import, deep import, raw palette,
+  undefined token과 tooltip-only required information fixture를 거절한다.
+- type negative fixture는 accessible name 없는 `IconButton`을 거절한다.
+- component test는 decorative icon, form control, Menu, Tabs, Drawer와 Toast를
+  검증한다.
+- Chromium/Firefox E2E는 compact Drawer의 native modal 상태, Escape, focus

+- 로컬 WebKit 실행은 host `libevent-2.1.so.7` 부재로 환경 검증이 남아 있으며
+  공급자 선택이나 product behavior의 PASS로 숨기지 않는다.
+
+## Rollback

+# VD-06: Intl과 typed local message catalog
+
+- 상태: Accepted
+- 결정일: 2026-07-26
+- 적용 브랜치: `feature-frontend-i18n-message-formatting-contract`
+- 재검토: 승인 locale·복수형 문법·번역 추출 workflow가 local catalog 범위를 넘을 때
+
+## 배경
+
+공통 셸, route surface, async/form 상태와 디자인 시스템 기본 문구가 JSX와
+JavaScript에 분산돼 있었다. 날짜는 일부 application mapper에서 고정 locale로
+가공되어 presentation이 locale을 바꿀 수 없었고, direction·누락 key·보간 실패
+정책도 없었다. 반면 현재 skeleton에는 번역 관리 서비스, 실제 번역 승인 절차,
+복잡한 ICU 문법이라는 제품 요구가 아직 없다. 이 단계에서 i18n vendor를 기본
+번들에 넣으면 소비 프로젝트가 제거하거나 다시 감싸야 할 의존성만 늘어난다.
+
+## 결정
+
+1. 표준 `Intl.DateTimeFormat`, `NumberFormat`, `RelativeTimeFormat`,
+   `ListFormat`, `PluralRules`와 typed local catalog를 기본 엔진으로 사용한다.
+2. `MessageKey`는 한국어 canonical catalog에서 도출하며 영어와 RTL smoke
+   catalog는 `satisfies Record<MessageKey, string>`으로 compile-time parity를
+   강제한다.
+3. 보간이 필요한 key는 `MessageParameters`에 key별 parameter object를
+   선언한다. 잘못된 key, 누락·초과 parameter는 TypeScript negative fixture가
+   거절한다.
+4. 기본 locale은 `ko-KR`, fallback locale도 `ko-KR`이다. 알려지지 않은 locale은
+   language fallback 후 `ko-KR`로 정규화한다. 알려지지 않은 key와 누락 보간은
+   raw key나 외부 값을 출력하지 않고 안전한 공통 fallback을 반환한다.
+5. `en-XA`는 영어 문구를 확장·accent 처리하는 pseudo locale이고 `ar-EG`는
+   RTL 동작 smoke locale이다. 이 두 locale은 실제 제품 번역 완료를 의미하지
+   않는다.
+6. 날짜 formatter의 기본 timezone은 테스트와 SSR/브라우저 결과가 흔들리지
+   않도록 `UTC`다. 제품 timezone이 필요하면 호출자가 명시한다. invalid
+   date/number/timezone은 `—`를 반환하고 throw하지 않는다.
+7. locale state는 React inbound concern이다. `LocaleProvider`가 copy,
+   formatter와 `<html lang/dir>`을 제공하며 application/domain은 미리 번역된
+   문자열 대신 의미 값과 timestamp를 반환한다.
+8. backend `message`, raw HTML, stack과 내부 key를 catalog 입력으로 신뢰하지
+   않는다. transport/application failure kind를 등록된 사용자 message key로
+   매핑한 뒤 presentation이 해석한다.
+9. key rename은 즉시 제거하지 않고 `MESSAGE_KEY_ALIASES`에 compatibility alias를
+   둔다. alias는 새 호출의 타입에 포함하지 않아 신규 코드는 canonical key만
+   사용한다.
+10. extraction, ICU rich message, 번역 SaaS 또는 framework adapter가 필요해지면
+    `presentation/i18n` public API 뒤에서 교체한다. vendor type은 feature와
+    design-system public prop으로 노출하지 않는다.
+
+## 실행 경계
+
+```text
+route/form/failure 의미 값
+  -> presentation message key
+  -> LocaleProvider
+  -> typed catalog / Intl formatter
+  -> text node와 accessible name
+```
+
+- canonical catalog: `src/presentation/i18n/catalog.ts`
+- feature contribution: `src/features/*/contracts/*-message-catalog.js`를
+  `src/features/installed-feature-messages.js`에서 조립
+- key/보간/fallback/alias: `message-contract.ts`
+- locale-safe value formatting: `formatters.ts`
+- React composition과 document metadata: `locale-provider.tsx`
+- public entry: `src/presentation/i18n/index.ts`
+
+## 검증
+
+- `check:i18n`은 catalog key와 placeholder parity, common UI의 한국어 literal,
+  backend message JSX 렌더링과 raw HTML 사용을 검사한다.
+- `check:i18n:fixture`는 세 금지 사례를 실제로 거절해야 성공으로 인정된다.
+- type negative fixture는 unknown key와 잘못된 parameter shape를 거절한다.
+- unit test는 fallback, alias, pseudo 확장, direction과 timezone/number/relative/
+  list/plural/select의 결정성을 검증한다.
+- component test는 document `lang/dir`, RTL Tabs와 direction-aware pagination,
+  Drawer semantics를 검증한다.
+- Playwright는 320px pseudo reflow와 RTL compact shell/Drawer/focus restore를
+  Chromium, Firefox, WebKit project에서 실행한다.
+
+## 한계와 재검토 조건
+
+현재 catalog는 실제 번역 승인, ICU rich text, locale별 plural 문장 전체 조합,
+메시지 추출/번역 메모리와 서버 locale negotiation을 제공하지 않는다. 다음 중
+하나가 확인되면 별도 ADR로 엔진을 재평가한다.
+
+- 세 개 이상의 실제 승인 locale과 번역 담당 workflow
+- 복수형·성별·select가 한 문장 안에서 중첩되는 제품 copy
+- server/client extraction, namespace lazy-loading 또는 번역 SaaS 연동
+- SSR locale negotiation과 hydration 일치가 필요한 rendering mode
+
+## Rollback
+
+`ko-KR` catalog가 기존 기본 문구를 보존하므로 provider를 고정 locale adapter로
+되돌려도 기본 UX를 유지한다. formatter/vendor 교체 시 public `message`,

+# 프론트엔드 플랫폼 역량 재검토
+
+## 1. 문서 목적
+
+이 문서는 도메인 기능과 실제 운영 환경의 배포 증적을 제외하고, 이 저장소가 새
+프론트엔드 제품의 출발점으로 제공해야 하는 공통 역량을 다시 평가한다. 평가
+기준은 다음과 같다.
+
+- 코드나 설정 파일이 존재하는지만 보지 않는다.
+- 부트스트랩부터 화면까지 실제 호출 경로가 연결되는지 확인한다.
+- 선언한 레지스트리와 정책이 런타임 및 CI에서 집행되는지 확인한다.
+- 기본 번들에 포함할 역량과 필요할 때 설치할 확장 역량을 구분한다.
+- 특정 벤더를 채택하더라도 제품 코드가 벤더 API에 직접 결합되지 않는지 확인한다.
+
+최초 검토 기준은 `develop`의 `cb195f8`이며, RP-01~RP-08 구현 결과를 이 문서에
+누적 반영했다. 이후 구현으로 경로나 세부 내용이 달라질 수 있으므로, 각 항목은
+문서의 경로뿐 아니라 해당 테스트와 아키텍처 게이트로 계속 검증해야 한다.
+
+## 2. 결론
+
+현재 저장소는 다음 기반이 강하다.
+
+- 런타임 설정과 릴리스 매니페스트 검증
+- 도메인, 애플리케이션, 프레젠테이션, outbound adapter의 의존 방향
+- 공통 HTTP 실패 형태와 제한된 retry 정책
+- 앱 셸, 반응형 내비게이션, 테마, 비동기 상태 표면
+- Vitest, Testing Library, MSW, Playwright, axe를 이용한 테스트 계층
+- CI 게이트 taxonomy와 호환성·보안·성능·릴리스 계약 문서
+
+그러나 “도메인 기능을 바로 추가할 수 있는 프론트엔드 플랫폼” 기준으로는 아직
+중요한 연결부가 빠져 있다. 가장 큰 문제는 공통 기능이 없다는 것보다 이미 있는
+기능이 실제 기능 화면의 표준 호출 경로로 조립되지 않았다는 점이다.
+
+특히 다음은 선행 해결이 필요하다.
+
+RP-01~RP-08에서 TypeScript 도구 안전망, application runtime 주입,
+query/mutation inbound adapter, HTTP 실행 계약과 executable route/release
+recovery 계약, 제거 가능한 reference 수직 슬라이스, form/page, design system과
+i18n 실행 경계는 구현됐다. 현재 선행 해결
+대상은 다음과 같다.
+
+1. diagnostics/telemetry 실제 producer 연결
+2. registry evidence, 공급망과 optional adapter recipe 심화 게이트
+
+따라서 현재 상태를 “프론트 공통부가 모두 구현됐다”고 표현하면 범위가 과장된다.
+더 정확한 표현은 다음과 같다.
+
+> 운영·안전 계약과 범용 앱 셸은 갖춰졌지만, 기능 개발자가 사용하는 application
+> API, 서버 상태, 폼, 라우팅, 페이지 패턴의 표준 수직 경로는 아직 보강이

+
+## 5. 우선순위별 발견 사항
+
+### 5.1 P0: 기능 개발을 막는 항목
+
+#### RP-02에서 application 런타임 우회 해결
+
+`src/bootstrap/composition-root.js`가 만든 typed application input API는
+production `ApplicationProvider`에 주입된다. raw auth, storage, telemetry와
+release port는 closure 안에 남고 UI는 session, preference, diagnostics와 runtime
+query만 사용한다.
+
+목표 상태:
+
+- `Application`은 UI가 호출할 query/command use case를 제공한다.
+- `ApplicationProvider`는 이 API만 React tree에 제공한다.
+- 페이지는 HTTP, storage, auth SDK, telemetry sink를 직접 호출하지 않는다.
+- bootstrap만 concrete outbound adapter를 알고 조합한다.
+- 실제 bootstrap부터 reference page까지 연결한 통합 테스트가 있다.
+
+#### RP-03에서 표준 서버 상태 bridge 구현
+
+`src/presentation/adapters/query` 한 경계만 `@tanstack/**`를 import한다.
+`useApplicationQuery`와 `useApplicationMutation`은 application result를 React
+lifecycle에 연결하며 cancellation, stale failure, duplicate submit, optimistic
+rollback, conflict resolution과 invalidation을 검증한다. 다른 presentation
+경로의 직접 TanStack import는 negative fixture가 거절한다.
+
+목표 상태:
+
+- canonical target인 `src/adapters/inbound/react/platform/query`에 벤더 연동을
+  한정한다. 마이그레이션 중에는 기존 `presentation`을 같은 inbound 경계로
+  취급하되 새 대체 경로를 만들지 않는다.
+- `useApplicationQuery`, `useApplicationMutation` 또는 같은 역할의 typed
+  controller hook을 제공한다.
+- HTTP retry와 query retry 중 한 계층만 재시도 책임을 갖는다.
+- loading, empty, refreshing, stale, offline, error, conflict, optimistic rollback을
+  reference feature에서 보여 준다.
+
+#### RP-01에서 TypeScript 검사 도구 안전망 구현
+
+현재 source는 모두 JS/JSX이고 `strict + allowJs + checkJs`를 사용한다. 이는 좋은
+중간 안전망이지만 다음 도구는 TS migration을 그대로 따라가지 못한다.
+
+- ESLint의 계층·보안 glob은 JS/JSX 중심이다.
+- registry scanner는 `.ts`와 `.tsx`를 찾지 않는다.
+- registry governance 경로가 `.js` 확장자로 고정되어 있다.
+- tests는 현재 `tsconfig.json` 검사 범위에서 빠진다.
+
+따라서 파일 확장자를 먼저 바꾸면 새 TS 코드가 일부 자동 검사에서 빠질 수 있다.
+TypeScript 전환은
+[TypeScript의 JavaScript migration 가이드](https://www.typescriptlang.org/docs/handbook/migrating-from-javascript.html)
+처럼 점진적으로 진행하되, 이 저장소에서는 tooling glob과 CI를 먼저 고쳐야 한다.
+
+#### RP-03에서 HTTP 선언과 실행의 차이 해결
+
+HTTP request builder는 path segment escaping, canonical optional/array search,
+Zod default/trim 결과의 실제 query/body 전송을 담당한다. runtime timeout과
+0/1/N max retry가 client factory에 주입되고 caller abort와 timeout을 다른 typed
+failure로 투영한다. validation 조기 반환은 fetch/timer 0회이며 success, schema
+failure, abort, timeout과 exhausted retry는 scheduler/listener cleanup을
+검증한다. HTTP 사건의 semantic telemetry 연결은 RP-09 범위다.
+
+client를 거대한 범용 함수로 계속 확장하지 말고 transport, request builder, auth,
+timeout, retry, decoder, mapper 책임을 분리해야 한다. application에는 범용 HTTP
+메서드보다 feature가 요구하는 gateway interface를 노출한다.
+
+#### RP-04에서 route registry를 실행 계약으로 전환
+
+platform route 계약과 `src/features/installed-feature-contracts.js`의 직렬화
+가능한 contribution을 기준으로
+`src/presentation/routes/app-router.tsx`가 Data Router route object와
+navigation을 생성한다. `route-runtime.tsx`는 lazy component의 실행 map만
+소유하며 contract/runtime 누락과 orphan은 TypeScript negative fixture와 registry
+gate가 모두 거절한다.
+
+현재 보장:
+
+- serializable contract와 executable runtime map을 분리한다.
+- `satisfies Record<RouteId, RouteRuntime>`로 양방향 완전성을 검사한다.
+- params/search는 Zod codec으로 경계에서 parse하고 URL builder도 같은 codec을
+  사용한다.
+- loading/error/chunk/access/title/navigation metadata를 실제 route object에
+  연결한다.
+- route change 시 boundary reset, title, focus와 scroll을 검증한다.
+- Vite manifest의 실제 dynamic entry와 route chunk ID를 release manifest에
+  연결하고, no-store manifest 재조회와 build/release 쌍별 1회 reload를
+  production application input까지 연결한다.
+
+#### RP-05에서 제거 가능한 reference feature 구현
+
+`src/features/reference-feature`가 domain, application input, outbound gateway,
+DTO/schema, mapper, route/API/query contract, query/mutation controller와 page를
+한 소유 경계에 둔다. production composition은 generic feature input catalog를
+통해 이 input을 주입하며 UI는 HTTP나 output port를 직접 보지 않는다.
+
+`test:sample-removal`은 임시 복제본에서 feature source/tests를 삭제하고 installed
+contract/runtime/adapter catalog를 빈 목록으로 재생성한다. 그 뒤 typecheck,
+architecture, registry, unit/integration, home smoke, build와 fixture ID 잔여
+0개를 검사한다. 설치 모드에서는 MSW를 사용한 bootstrap → router → application
+→ HTTP → schema → mapper → query cache → page 수직 테스트가 실행된다.
+
+#### 비동기·복구 상태의 불변식이 닫혀 있지 않다
+
+공통 async model과 gallery가 있지만 선언 가능한 상태 조합 중 일부는 사용자
+행동과 모순될 수 있다. stale data가 있는 degraded 상태와 refreshing, mutation
+pending과 conflict, retry button과 실제 handler 존재 여부를 typed state로
+닫아야 한다. 상태를 boolean 여러 개로 조합하지 않고 다음과 같은 discriminated
+state와 action capability로 표현한다.
+
+```text
+initial-loading
+ready
+refreshing-with-data
+empty
+degraded-with-data
+terminal-error
+mutation-pending
+mutation-conflict
+```
+
+RP-04에서 lazy import failure는 `ChunkRecoveryBoundary` → application recovery
+input → `ReleaseInfoPort.refresh()`의 no-store manifest 조회 → build/release 쌍
+guard → browser navigation adapter의 1회 reload로 연결됐다. 일반 render
+failure는 이 경로에서 제외되고, 반복 실패·offline·malformed manifest·storage
+실패는 지원 표면으로 fail-closed된다.
+
+#### telemetry, registry, 공급망 gate의 실행 깊이가 부족하다
+
+telemetry registry에는 여러 사건이 있지만 실제 production producer는 제한적이다.
+boot, API attempt/final failure, auth recovery, storage/cache degradation, release/chunk
+recovery를 registry 사건에 연결해야 한다.
+
+registry/compatibility 검사는 다음까지 확장한다.
+
+- ID와 enum/type의 양방향 완전성
+- referenced schema/message/token의 존재
+- 실행 코드에서 소비되지 않는 orphan 항목
+- 기준 commit과 현재 commit 사이의 실제 contract diff
+- breaking change의 version/migration/rollback metadata
+
+공급망 검사는 단순 문자열 secret 탐지에 머물지 않고 transitive dependency,
+known vulnerability, license policy, SBOM/provenance를 pinned tool로 검사해야 한다.
+도구 장애와 취약점 발견을 구분하고, 예외에는 owner·사유·만료일을 요구한다.
+
+### 5.2 P1: 공통 플랫폼 기본 제공 항목
+
+- RP-06에서 완료한 schema 기반 form facade와 field/error/pending/dirty/422 정책 유지
+- RP-06에서 완료한 standard, collection, detail, form, status page template의 public entry 정리
+- 접근 가능한 drawer, menu, popover, select 같은 interaction primitive
+- token → primitive → pattern → template로 이어지는 디자인 시스템
+- Lucide를 감싼 local icon registry와 `IconButton`
+- typed message key, locale provider, formatter, pseudo-locale/RTL smoke
+- redacted structured diagnostics/logger와 telemetry wiring
+- Storybook 또는 동급 isolated UI workshop
+- Playwright visual baseline, shared MSW scenarios, built-dist E2E
+- React Hooks, JSX accessibility, TanStack Query 관련 lint
+- source와 tests를 모두 포함하는 TypeScript project references
+- registry/compatibility의 실제 diff와 orphan reference 검사
+- transitive vulnerability, license, SBOM/provenance 공급망 gate
+
+#### RP-08에서 국제화 실행 경계 구현
+
+`src/presentation/i18n`은 shell, route, async/form error, page template와
+design-system 기본 copy의 canonical 경계다. `MessageKey`와 key별
+`MessageParameters`가 잘못된 key/보간을 compile time에 막고, runtime
+`resolveMessage`는 unknown locale/key와 누락 보간에서 raw 값 대신 안전한
+fallback을 반환한다. application mapper는 locale-formatted date를 반환하지
+않고 timestamp를 유지하며 presentation formatter가 `UTC` 또는 명시 timezone을
+적용한다.
+
+`LocaleProvider`는 `ko-KR`, `en-US`, `en-XA`, `ar-EG` smoke set과 document
+`lang/dir`을 동기화한다. `en-XA`는 긴 문구 reflow, `ar-EG`는 logical CSS,
+Drawer, Tabs arrow와 pagination 방향 icon을 검증하기 위한 개발 locale이다.
+실제 아랍어 번역 완료를 뜻하지 않는다. `check:i18n`과 negative fixture는 common
+UI literal, backend raw message render와 raw HTML interpolation을 거절한다.
+새 key rename은 canonical type에는 넣지 않고 runtime alias/migration window로
+호환한다.
+
+### 5.3 P2: 경계와 recipe를 제공할 선택 항목
+
+다음 기능을 모든 앱의 초기 번들에 설치할 필요는 없다. 대신 port 또는 local
+vendor facade, 선택 조건, 실패 정책, 테스트 fixture를 문서로 제공한다.
+
+| capability | 대표 기술 | 기본 제공할 경계 | 실제 설치 조건 |
+| --- | --- | --- | --- |
+| realtime | WebSocket, SSE | subscribe/unsubscribe, reconnect, resume, heartbeat | 서버가 push event를 제공할 때 |
+| offline storage | IndexedDB | versioned repository, migration, quota failure | offline read/write가 제품 요구일 때 |
+| background/cache | Service Worker, PWA | cache ownership, update, rollback recipe | installable/offline 앱일 때 |
+| file transfer | presigned HTTP, multipart | progress, cancel, size/type validation | 업로드·대용량 다운로드가 있을 때 |
+| generated API | OpenAPI, GraphQL, gRPC-Web | generated client를 gateway 뒤에 감싸는 규칙 | 서버 계약 형식이 확정됐을 때 |
+| feature flag | local/remote flag provider | typed flag key, default, stale behavior | staged rollout가 필요할 때 |
+| worker | Web Worker | request/result/cancel protocol | UI thread를 막는 CPU 작업이 있을 때 |
+| multi-tab | BroadcastChannel | event versioning, source ID, conflict policy | 탭 간 동기화가 필요할 때 |
+| browser capability | clipboard, notification, media | permission/result port | 해당 UX가 있을 때 |
+| client workflow | Zustand, Redux Toolkit, state machine | state ownership decision과 local facade | cross-feature workflow가 실제로 생길 때 |
+| large data UI | virtualization, data grid | owned component facade | 데이터 규모가 측정 기준을 넘을 때 |
+| analytics/error sink | vendor SDK, OpenTelemetry | redaction, consent, sampling adapter | 운영 provider와 정책이 정해졌을 때 |
+
+서버의 Redis, MongoDB, PostgreSQL, MinIO를 브라우저가 직접 연결하는 구조는 기본
+frontend adapter catalog에 넣지 않는다. 브라우저는 권한 있는 backend API/BFF를
+통해 이 자원에 접근해야 한다. 프론트에서 대응되는 변화 지점은 데이터베이스
+vendor가 아니라 HTTP/GraphQL/gRPC-Web, realtime, file transfer, cache, storage,
+worker, browser capability 같은 프로토콜·런타임 capability다.
+
+### 성능 최적화는 모두 adapter 문제인가
+
+아니다. 먼저 측정하고 병목의 소유 계층에 맞는 수단을 적용한다.
+
+| 문제 | 기본 제공할 수단 | adapter/facade가 필요한 경우 |
+| --- | --- | --- |
+| 초기 JS가 큼 | route/feature lazy loading, bundle budget, dependency inventory | remote module이나 별도 delivery 전략이 있을 때 |
+| 중복 네트워크 | TanStack deduplication/cache, abort, bounded retry | offline cache나 generated client를 교체할 때 |
+| 느린 화면 전환 | prefetch policy, stable shell, cached-data surface | route별 prefetch provider가 필요할 때 |
+| 긴 main-thread task | profiler 기준으로 계산 분리 | Web Worker message adapter |
+| 대량 목록 | pagination과 server filter를 우선 | virtualizer/data-grid facade |
+| 이미지 전송량 | width/height, lazy loading, responsive source 규칙 | Image CDN URL builder adapter |
+| 재방문/offline | HTTP cache contract | Service Worker/IndexedDB adapter |
+| 불필요한 render | 상태 소유권 축소와 component boundary | 보통 adapter가 아니며 측정 후 memoization |
+
+기본 skeleton은 bundle budget, lazy route, query cancellation/cache, responsive
+image 규칙, stable layout, lab performance test를 제공한다. Web Worker,
+virtualization, Image CDN, Service Worker는 실제 병목과 제품 요구가 확인될 때
+설치한다. 라이브러리를 미리 많이 넣는 것은 최적화가 아니라 초기 번들·공급망
+표면을 늘리는 일이 될 수 있다.
+
+## 6. 질문별 직접 답변
+
+### 프론트도 inbound/outbound로 나누는가
+
+나눈다. 현재 구조에서는 `presentation`이 사실상 inbound adapter이고
+`src/adapters`가 outbound adapter다. 이름과 문서가 이 역할을 명확히 드러내지
+않아 모두 같은 adapter처럼 보인 것이다.
+
+| 역할 | 프론트 예 |
+| --- | --- |
+| input/inbound port | `ListResources`, `CreateResource` 같은 application API |
+| inbound adapter | React page/controller, router, form event, push-event translator |
+| output/outbound port | resource gateway, session, storage, clock, diagnostics |
+| outbound adapter | HTTP, auth SDK, browser storage, TanStack cache, telemetry sink |
+
+React, router, form library, icon library마다 application port를 만들 필요는 없다.
+UI 내부 교체만 필요한 라이브러리는 React inbound adapter 내부 vendor facade로
+충분하다. port는 application 정책과 외부 소유권 사이의 경계에 둔다.
+
+### 왜 현재 모두 `adapters` 아래에 있는가
+
+실제로 모두 있지는 않다. UI driver가 `presentation`이라는 이름으로 분리돼 있고,
+`adapters`에는 주로 outbound 구현이 있다. 다만 다음 두 대안 중 하나를 명시적으로
+선택해야 한다.
+
+1. 변경량을 줄여 `presentation = inbound adapter`로 문서화하고
+   `adapters/outbound`만 명시한다.
+2. TypeScript/feature migration과 함께 `adapters/inbound/react`와
+   `adapters/outbound`로 재구성한다.
+
+이 저장소는 input API 부재와 flat contracts 문제도 함께 고쳐야 하므로 두 번째
+구조가 장기적으로 더 명확하다. 단, 대규모 rename 자체를 기능 개선으로 세지 말고
+architecture gate와 수직 reference feature가 먼저 또는 같은 브랜치에서
+증명되어야 한다.
+
+### TypeScript로 바꾸는 것이 좋은가
+
+좋다. 특히 registry ID, Result/error union, port generic, route params/search,
+component variant를 컴파일 시점에 닫을 수 있다. 다만 일괄 rename은 권장하지
+않는다. tooling → core contracts → application ports/use cases → outbound →
+bootstrap → React TSX → tests 순서로 이동한다.
+
+### store 기본 설정이 필요한가
+
+상태 전략은 기본 제공해야 하지만 범용 global store dependency는 필수로 넣지
+않는다.
+
+- local interaction: `useState`/`useReducer`
+- shareable navigation state: URL
+- server state: TanStack Query
+- form state: form facade
+- low-frequency cross-cutting state: context 또는 typed external store
+- complex cross-feature workflow: Zustand/Redux Toolkit/state machine 중 선택
+- persistence: `StoragePort`
+
+서버 데이터를 global store에 복사하지 않는 규칙이 중요하다.
+[TanStack Query](https://tanstack.com/query/latest/docs/framework/react/overview),
+[Redux Toolkit](https://redux-toolkit.js.org/introduction/getting-started),
+[Zustand](https://zustand.docs.pmnd.rs/)의 역할은 서로 같지 않다.
+
+### retry, API client, logger, token manager, error, validation은 어디에 있는가
+
+- retry: `src/adapters/http/retry-policy.js`, 부분 준비
+- API client: `src/adapters/http/client.js`, 부분 준비
+- logger: 없음. telemetry와 분리하거나 diagnostics port로 합치는 결정 필요
+- token manager: 의도적으로 없음. opaque external auth owner가 credential을 소유
+- error: `src/contracts/errors.js`와 HTTP normalization, 부분 준비
+- validation: runtime/API Zod는 존재, route/form/domain 분리는 미완성
+
+token manager를 기본으로 추가하지 않는 이유는 token lifecycle이 인증 방식마다
+다르고 localStorage token을 일반 해법으로 만들면 보안 위험이 커지기 때문이다.
+BFF HttpOnly cookie 또는 OIDC/Auth SDK가 credential을 소유하도록 두고, SPA
+memory token이 필요한 프로젝트만 auth adapter를 추가한다.
+
+### Lucide React를 쓰면 디자인 시스템이 되는가
+
+아니다. [Lucide React](https://lucide.dev/guide/packages/lucide-react)는
+tree-shakable SVG icon source로 적절하지만 select, dialog, menu, focus management
+같은 UI behavior는 제공하지 않는다. Lucide는 local icon facade 뒤에 두고,
+복잡한 interaction은 [Radix Primitives](https://www.radix-ui.com/primitives/docs/overview/introduction)
+또는 React Aria 계열과 같은 headless primitive를 owned wrapper 뒤에서 선택한다.
+
+### 테스트는 현재 어떤 상태인가
+
+테스트 도구 구성은 강한 편이다. 다만 다음이 빠져 있다.
+
+- TS source와 test 전체 typecheck
+- 실제 composition root부터 page까지의 통합
+- query/mutation controller와 optimistic rollback
+- route registry/runtime map 정합성은 RP-04에서 unit, component, negative
+  registry/type fixture와 built artifact 검증으로 구현됨
+- runtime timeout/retry와 path/query/parsed body
+- shared MSW scenario catalog
+- isolated component stories와 interaction test
+- stable-environment visual regression
+- built `dist` 대상 release E2E
+- 위험 기반 coverage gate
+
+### 라우팅 전략은 무엇이 적절한가
+
+현재 client-only clean architecture와 TanStack Query 조합은 유지하되, 목표
+skeleton은 React Router Data Mode의 route object, blocker, scroll restoration,
+route error 경계를 사용한다. 서버 상태의 소유자는 계속 application input과
+TanStack Query이며 loader/action이 같은 데이터를 별도로 요청하지 않는다.
+[React Router 공식 mode 설명](https://reactrouter.com/start/modes)에 따라
+Framework Mode는 SSR/static generation, route module, framework-owned data
+loading을 실제 요구할 때만 선택한다.
+
+### 바로 쓸 수 있는 디자인 패턴은 무엇을 제공해야 하는가
+
+패턴 이름만 나열하지 않고 다음 executable blueprint를 제공해야 한다.
+
+- page controller: route/form event를 application input으로 변환
+- query/mutation adapter: server state lifecycle을 React에 연결
+- command/query use case: 읽기와 상태 변경 의도를 분리
+- gateway: application이 외부 데이터 소유자를 추상화
+- mapper/anti-corruption layer: transport DTO를 core model로 변환
+- Result + failure mapper: throw와 사용자 메시지 경계를 통제
+- strategy: retry, cache, auth recovery, feature flag 정책 교체
+- observer/external store: session/theme/realtime 구독
+- state machine: 복잡한 workflow에만 선택적으로 사용
+- compound component/headless wrapper: 접근 가능한 복합 UI를 소유
+- page template: layout과 상태 표면을 데이터 소유권에서 분리
+
+## 7. 실전 투입 준비 완료 기준
+
+막연한 백분율 대신 아래 조건을 모두 자동 또는 명시적 검토로 확인한다.
+
+1. reference feature가 route → controller → input use case → output gateway →
+   adapter → mapper → query cache → UI 상태 표면을 통과한다.
+2. application input API 외에는 UI에서 outbound dependency에 접근할 수 없다.
+3. TypeScript source와 tests가 strict 검사되고 JS 우회 경로가 없다.
+4. HTTP path/query/body/auth/timeout/retry/cancel/decode 실패가 계약 테스트된다.
+5. typed route registry와 runtime map이 양방향 완전성을 가진다.
+6. list/detail/form/status page template과 form error 정책이 준비돼 있다.
+7. 디자인 시스템 primitive/pattern이 isolated workshop, interaction, a11y,
+   visual test를 가진다.
+8. sample/reference feature 전체 삭제 후 typecheck/test/build가 통과한다.
+9. optional adapter는 설치 조건, 보안 경계, 실패 정책, 테스트 recipe가 있다.
+10. 새 feature 추가 문서가 파일 경로, 금지 의존, 실패 상태, 테스트, 검증 명령까지
+    안내한다.
+
+이 기준은 배포 provider, 실제 인증 tenant, 운영 telemetry vendor, production field
+data 같은 프로젝트별 외부 작업을 포함하지 않는다.

+`PASS_SCOPED` reviewer evidence applies to the canonical draw.io diagram named
+in `review-ledger.json`, not automatically to edits in this file.
+
+```mermaid
+flowchart LR
+  Bootstrap[bootstrap / composition root] --> Presentation[presentation]
+  Bootstrap --> Adapters[adapters]
+  Presentation --> Shell[app shell and route surfaces]
+  Shell --> Providers[session and theme providers]
+  Presentation --> Application[application]
+  Adapters --> Application
+  Application --> Domain[domain]
+  Contracts[contract registries] --> Bootstrap
+  Contracts --> Adapters
+  Contracts --> Presentation
+```
+
+The intended dependency rule points inward: presentation calls application use
+cases, adapters implement application ports, and only the composition root
+selects concrete adapters. Contract registries are the intended named source
+for routes, API operations, environment values, storage keys, errors, queries,
+telemetry, and release tokens. The platform review below records where the
+current runtime still bypasses that target or duplicates registry metadata.
+
+In ports-and-adapters terms, `presentation` is the current inbound adapter and
+`adapters` contains the current outbound implementations. The target design
+makes this role explicit, introduces application input ports, and prevents the
+React tree from receiving raw outbound dependencies:
+
+```mermaid
+flowchart LR
+  Driver[User, route, browser event] --> Inbound[React inbound adapter]
+  Inbound --> Input[Application input API]
+  Input --> UseCase[Use cases]
+  UseCase --> Output[Application output ports]
+  Output --> Outbound[HTTP, auth, storage, query, telemetry adapters]
+  Bootstrap2[Composition root] -. selects and injects .-> Input
+  Bootstrap2 -. selects and injects .-> Outbound
+```
+
+The current executable route tree is mounted only after runtime configuration
+and release-manifest coherence pass. It receives the composed query client,
+credential-opaque session port, storage port, telemetry port, and immutable
+build ID. Generic starter pages do not depend on the removable reference
+feature.
+
+This describes the current starter composition, not the completed target. The
+capability review found that raw outbound capabilities still reach the React
+tree, the composed application facade is not yet its entry point, and several
+route, HTTP, recovery, telemetry, and reference-feature removal contracts are only
+partially connected. Use the following documents for the evidence and migration

+# 라우팅, 페이지 템플릿, 재사용 패턴
+
+## 1. 목적
+
+이 문서는 도메인과 무관하게 다음을 바로 구현할 수 있는 기준을 제공한다.
+
+- typed route와 안전한 URL
+- session, permission, feature flag guard
+- lazy chunk의 loading/error/recovery
+- route 이동 시 focus, scroll, 취소, dirty form 처리
+- list, detail, form, status 등 공통 page template
+- page controller와 application input use case의 연결
+- 프론트엔드에서 반복 사용하는 설계 패턴
+
+## 2. 현재 상태와 구현 기준
+
+RP-04 이후 route runtime과 RP-06 page/form platform에는 다음 장점이 있다.
+
+- route registry가 path와 access policy를 소유한다.
+- contract에서 Data Router route object와 navigation을 생성한다.
+- runtime map이 route component를 lazy import하고 codec을 연결한다.
+- 앱 셸과 보호 route, not-found surface가 있다.
+- route heading focus와 비동기/render error boundary가 있다.
+- redirect loop와 chunk recovery가 bounded production call graph에 연결돼 있다.
+- `src/presentation/templates`가 standard/collection/detail/form/status slot,
+  landmark와 responsive layout을 제공한다.
+- `src/presentation/forms`가 첫 오류 focus, error summary, 422 mapping,
+  duplicate submit과 dirty route blocker를 소유한다.
+- reference feature의 list/detail/create/status route가 네 template variation을
+  production composition에서 실행한다.
+
+platform route 계약, `src/features/installed-feature-contracts.js`,
+`src/features/installed-feature-runtimes.tsx`의 완전성은 TypeScript와 registry
+negative fixture가 함께 검사한다. params/search codec, loading/error surface,
+access, title, navigation, chunk ID는
+`src/presentation/routes/app-router.tsx`에서 모두 소비된다. built Vite
+manifest의 dynamic entry는 release manifest route chunk map과 검증되며,
+`ChunkRecoveryBoundary`는 일반 render error와 chunk rejection을 분리한다.
+
+template는 데이터를 가져오지 않는다. reference page controller가 route input과
+application input을 query/form facade에 연결하고, template에는 render할 slot과
+안전한 callback만 전달한다. 이 분리는
+`page-templates-own-layout-only` dependency rule과 forbidden import fixture가
+검증한다.
+
+## 3. React Router mode 결정
+
+[React Router 공식 mode 설명](https://reactrouter.com/start/modes)과
+[Data Mode custom setup](https://reactrouter.com/start/data/custom)은
+Declarative, Data, Framework Mode를 구분한다.
+
+저장소에는 현재 React Router `7.18.1`이 고정돼 있다. 구현 브랜치는 공식 문서의
+동일 버전 API를 기준으로 하고 router version upgrade를 Data Mode 구조 변경과
+같은 브랜치에 섞지 않는다. 위 공식 링크의 기본 표시 버전이 바뀌면 version
+selector를 `7.18.1`로 맞춰 확인한다.
+
+| mode | 선택 조건 | 이 저장소에서의 판단 |
+| --- | --- | --- |
+| Declarative | React composition과 외부 data layer가 route data를 소유 | RP-04 이전 기준선 |
+| Data | route object, blocker, scroll restoration, pending/navigation state가 필요 | VD-03으로 채택하고 RP-04에서 구현 |
+| Framework | route module, type-safe href, code splitting, SSR/static 전략을 framework가 소유 | client-only skeleton 기본값으로는 범위가 큼 |
+
+채택한 결정:
+
+- client-only SPA와 TanStack Query/application use case를 유지한다.
+- `createBrowserRouter`와 `RouterProvider` 기반 Data Mode를 사용한다.
+- Data Mode를 선택하는 이유는 route object, navigation blocker, scroll
+  restoration, route error 경계를 일관되게 소유하기 위해서다. loader/action으로
+  서버 상태를 다시 소유하기 위해서가 아니다.
+- loader/action을 추가할 때는 TanStack Query/application input을 prefetch하거나
+  호출하는 한 가지 소유 경로만 사용한다.
+- 같은 데이터를 route loader와 TanStack Query가 각각 가져오지 않는다.
+- SSR/static generation을 선택하기 전에는 Framework Mode를 기본값으로 만들지
+  않는다.
+
+결정 근거와 rollback 경계는
+`docs/architecture/decisions/VD-03-react-router-data-mode.md`에 고정한다.
+Data Mode를 사용할 수 없는 프로젝트만 별도 ADR과
+`NavigationLifecycleAdapter`를 구현한다.
+
+## 4. route 계약과 runtime map
+
+### 4.1 두 종류의 레지스트리
+
+직렬화 가능한 contract와 React implementation을 분리한다.
+
+```ts
+export const routeContracts = {
+  home: {
+    id: "home",
+    path: "/",
+    access: "public",
+    navigation: "primary",
+    titleKey: "route.home.title",
+    loadingSurface: "page",
+    errorSurface: "page",
+    chunkId: "home",
+  },
+  resourceDetail: {
+    id: "resourceDetail",
+    path: "/examples/resources/:resourceId",
+    access: "authenticated",
+    navigation: "hidden",
+    titleKey: "route.resourceDetail.title",
+    loadingSurface: "detail",
+    errorSurface: "detail",
+    chunkId: "reference-resource-detail",
+  },
+} as const satisfies RouteContractRegistry;
+```
+
+```tsx
+export const routeRuntime = {
+  home: {
+    Component: lazy(() => import("../pages/home-page")),
+    paramsCodec: emptyParamsCodec,
+    searchCodec: emptySearchCodec,
+  },
+  resourceDetail: {
+    Component: lazy(() => import("../features/resources/resource-detail-page")),
+    paramsCodec: resourceDetailParamsCodec,
+    searchCodec: resourceDetailSearchCodec,
+  },
+} satisfies Record<RouteId, RouteRuntime>;
+```
+
+요구 사항:
+
+- contract key와 `id`가 다르면 typecheck 실패
+- contract에는 함수, component, schema instance처럼 직렬화 불가능한 값을 넣지 않음
+- runtime map에는 실제 lazy component와 codec/guard만 둠
+- contract의 모든 route가 runtime에 있고 runtime의 모든 key가 contract에 있음
+- navigation은 contract에서 파생
+- build chunk manifest와 `chunkId` 대응을 검증
+- public runtime config나 server가 route component 이름을 임의 지정할 수 없음
+
+### 4.2 params와 search codec
+
+URL은 외부 입력이다. page에서 `useParams()` 결과를 cast하지 않는다.
+
+```ts
+const resourceDetailParamsSchema = z.object({
+  resourceId: z.string().trim().min(1).max(100),
+});
+
+const resourceListSearchSchema = z.object({
+  q: z.string().trim().max(100).catch(""),
+  page: z.coerce.number().int().min(1).catch(1),
+  sort: z.enum(["updated-desc", "name-asc"]).catch("updated-desc"),
+});
+```
+
+path params와 search params는 입력 형태와 serialization 규칙이 다르므로 같은
+interface로 뭉치지 않는다. 각각 parse와 serialize를 제공한다.
+
+```ts
+interface PathParamsCodec<T> {
+  parse(
+    input: Readonly<Record<string, string | undefined>>,
+  ): Result<T, RouteInputFailure>;
+  serialize(value: T): Readonly<Record<string, string>>;
+}
+
+interface SearchParamsCodec<T> {
+  parse(input: URLSearchParams): Result<T, RouteInputFailure>;
+  serialize(value: T): URLSearchParams;
+}
+```
+
+규칙:
+
+- route input parse 실패와 backend 404를 구분한다.
+- 알 수 없는 search key를 보존할지 제거할지 route별로 선언한다.
+- default value를 URL에 항상 쓸지 생략할지 codec이 결정한다.
+- array/date/boolean encoding을 feature마다 다르게 만들지 않는다.
+- navigation link도 codec 기반 builder를 사용한다.
+- query key에는 parsed value만 사용한다.
+- 검색어·식별자를 telemetry에 기록하기 전에 sensitivity policy를 적용한다.
+
+### 4.3 route object 생성
+
+하나의 factory가 다음을 조합한다.
+
+```text
+route contract
+  + runtime component/codecs
+  + access guard
+  + feature flag guard
+  + suspense surface
+  + render/chunk error surface
+  + title/focus/scroll behavior
+  -> executable route object/tree
+```
+
+JSX에서 route별 `<Route>`를 다시 나열하지 않는다. nested layout이 필요한 경우
+contract에 parent ID를 두고 cycle/orphan/duplicate path를 registry gate에서
+검사한다.
+
+## 5. guard와 권한
+
+### 5.1 guard 순서
+
+권장 순서:
+
+1. runtime/bootstrap readiness
+2. route 존재와 URL parse
+3. feature flag
+4. session readiness
+5. authentication
+6. coarse client permission hint
+7. route component
+8. server authorization result
+
+client guard는 UX 최적화일 뿐 보안 경계가 아니다. API/BFF가 항상 최종 권한을
+검사한다.
+
+### 5.2 guard 결과
+
+```ts
+type GuardDecision =
+  | { kind: "allow" }
+  | { kind: "redirect"; to: SafeLocation; reason: RedirectReason }
+  | { kind: "render"; surface: "auth-required" | "forbidden" | "not-found" };
+```
+
+- redirect에는 origin route와 bounded return URL을 사용한다.
+- 외부 redirect는 allowlist를 거친다.
+- 동일한 route 쌍을 반복하는 redirect loop를 차단한다.
+- session이 아직 resolving이면 forbidden으로 단정하지 않는다.
+- server가 403을 반환하면 client claim을 신뢰해 화면을 계속 보여 주지 않는다.
+
+## 6. navigation lifecycle
+
+### 6.1 loading
+
+loading surface를 route metadata에 연결한다.
+
+| surface | 사용 |
+| --- | --- |
+| shell | 초기 앱 셸 진입 |
+| page | 새로운 전체 페이지 |
+| collection | table/list 구조 유지 |
+| detail | metadata/content 구조 유지 |
+| form | 필드 layout 구조 유지 |
+| inline | 부분 action |
+
+cached data가 있으면 full-page skeleton으로 교체하지 않고 refreshing indicator를
+사용한다. `prefers-reduced-motion`에서 skeleton animation을 줄인다.
+
+### 6.2 error와 lazy chunk recovery
+
+route error boundary는 다음을 구분한다.
+
+- render/programmer error
+- dynamic import/chunk load error
+- application `AppFailure`
+- URL parse failure
+- not found
+
+chunk recovery 순서:
+
+1. 현재 build ID와 release manifest를 확인한다.
+2. 새 manifest가 확인되고 같은 build에 대해 reload하지 않았다면 한 번만 reload한다.
+3. 같은 failure가 반복되면 reload loop를 막는다.
+4. 안전한 support surface와 trace/build ID를 표시한다.
+5. recovery 결과를 redacted diagnostics에 기록한다.
+
+custom fallback을 넘겨 retry/reset 기능을 잃지 않게 한다. boundary는
+`location.key` 또는 route ID가 바뀌면 적절히 reset된다.
+
+### 6.3 focus와 scroll
+
+- route 성공 후 `main`의 page heading에 programmatic focus
+- mouse 사용자가 불필요한 focus ring을 보지 않게 할 수는 있지만 keyboard focus
+  indication을 전역으로 제거하지 않음
+- modal/drawer가 닫히면 opener에 focus 복원
+- backward/forward navigation은 저장한 scroll 복원
+- 새 primary route는 top으로 이동
+- hash target은 fixed header offset과 focus 가능 여부를 처리
+- screen reader용 route title/live announcement는 중복 발표를 피함
+
+### 6.4 취소와 dirty form
+
+- route 이동 시 진행 중 query signal을 취소한다.
+- mutation은 취소 안전성이 명확할 때만 취소한다.
+- dirty form blocker는 browser unload와 in-app navigation을 구분한다.
+- 성공 저장 후 blocker를 해제한 다음 이동한다.
+- autosave가 있는 form은 pending/failed 상태를 별도로 알린다.
+- confirm dialog는 공통 accessible primitive를 사용한다.
+
+## 7. 페이지 템플릿
+
+template은 데이터를 가져오거나 application을 호출하지 않는다. 슬롯, landmark,
+focus target, responsive layout, 상태 위치만 소유한다.
+
+### 7.1 `StandardPageTemplate`
+
+슬롯:
+
+- breadcrumb 또는 back link
+- title, description, status badge
+- primary/secondary actions
+- notices
+- content
+- contextual aside
+
+작은 화면에서 action wrapping 순서와 heading hierarchy를 보장한다.
+
+### 7.2 `CollectionPageTemplate`
+
+슬롯과 상태:
+
+- title/actions
+- search/filter/sort toolbar
+- active filter summary와 reset
+- result count
+- table/list/card view
+- pagination 또는 load-more
+- initial loading, refreshing, empty-first-use, empty-filtered, error
+- bulk selection/action
+
+URL이 filter, sort, page를 소유한다. template은 query 상태를 직접 읽지 않는다.
+
+### 7.3 `DetailPageTemplate`
+
+- breadcrumb/back
+- title/status/actions
+- summary metadata
+- main sections
+- related/context aside
+- loading/not-found/forbidden/error
+- destructive action confirmation 위치
+
+식별자가 바뀔 때 이전 entity 내용과 새 loading 상태를 혼동하지 않게 key/reset
+정책을 명시한다.
+
+### 7.4 `FormPageTemplate`
+
+- title/description
+- error summary
+- field groups
+- optional aside/help
+- sticky 또는 normal action bar
+- submit/cancel
+- submitting/saved/conflict/unavailable
+- dirty navigation confirmation
+
+template은 특정 form vendor를 import하지 않는다.
+
+### 7.5 `StatusPageTemplate`
+
+다음 변형을 제공한다.
+
+- unauthenticated
+- forbidden
+- not found
+- unavailable
+- offline
+- maintenance
+- unexpected
+
+각 변형은 heading, 짧은 설명, 안전한 primary/secondary action, 선택적 trace ID를
+갖는다. raw stack/response를 표시하지 않는다.
+
+### 7.6 선택 template
+
+다음은 project 필요가 있을 때 추가한다.
+
+- `SettingsPageTemplate`
+- `DashboardGridTemplate`
+- `SplitPaneTemplate`
+- `WizardTemplate`
+- `FullScreenTaskTemplate`
+
+## 8. page controller 패턴
+
+page를 세 부분으로 나눈다.
+
+```text
+route adapter
+  parses URL and guard context
+      ↓
+controller hook
+  invokes application query/mutation and maps UI events
+      ↓
+page view
+  renders template and design-system components
+```
+
+예:
+
+```tsx
+export function ResourceListRoute() {
+  const input = useRouteInput(resourceListRoute);
+  if (!input.ok) return <InvalidRouteSurface failure={input.error} />;
+
+  return <ResourceListController input={input.value} />;
+}
+
+function ResourceListController({ input }: ResourceListControllerProps) {
+  const controller = useResourceListController(input);
+  return <ResourceListPage controller={controller} />;
+}
+```
+
+route parse boundary와 controller component를 분리하므로 controller hook은
+조건부로 호출되지 않는다.
+
+controller가 소유하는 것:
+
+- parsed route input을 application input으로 변환
+- query/mutation state
+- pagination/filter/navigation event
+- retry/refresh/action callbacks
+- view model projection
+
+view가 소유하는 것:
+
+- semantic markup
+- template/component 조립
+- focus target
+- 사용자의 local-only interaction
+
+controller가 소유하지 않는 것:
+
+- HTTP URL 조립
+- credential
+- transport DTO parse
+- 도메인 invariant
+- raw vendor SDK
+
+## 9. 권장 패턴 카탈로그
+
+| 패턴 | 적용 위치 | 쓰는 이유 | 오용 |
+| --- | --- | --- | --- |
+| Ports and Adapters | application 외부 경계 | 정책과 기술 교체 분리 | 모든 작은 UI library에 port 생성 |
+| Command/Query | application input | 읽기/변경 의도와 정책 분리 | CQRS 인프라를 필요 없이 도입 |
+| Gateway | output port | 외부 데이터 capability 표현 | `get/post` 범용 HTTP를 application에 노출 |
+| Anti-Corruption Mapper | outbound feature adapter | DTO 변화가 core로 전파되지 않게 함 | 단순 object spread로 타입만 바꿈 |
+| Result | 예상 실패 | 실패 종류와 처리 경로를 닫음 | programmer error까지 모두 Result로 숨김 |
+| Controller/View | inbound React | data lifecycle과 markup 분리 | 거대한 hook 하나에 모든 feature 로직 집중 |
+| Strategy | retry/cache/auth recovery | 정책 교체와 테스트 가능성 | 설정 한 줄도 interface로 과도 추상화 |
+| Observer/External Store | session/theme/realtime | React 외부 소유 상태 구독 | server state를 다시 external store에 복제 |
+| State Machine | 복잡한 workflow | 유효 전이와 보상 명시 | 단순 modal open에 도입 |
+| Headless/Compound Component | 복합 UI | behavior와 style/slot 분리 | vendor primitive를 제품 전역에 직접 노출 |
+| Adapter Facade | icon/form/i18n vendor | React inbound 내부 vendor 교체 경계 | application port로 승격 |
+| Page Template | 반복 layout/state | 접근성과 반응형 구조 재사용 | data fetching을 template에 포함 |
+| Registry + Runtime Map | route/operation/event | 선언과 실행 완전성 | 모든 설정을 하나의 거대 전역 파일에 집중 |
+
+RP-08 이후 route contract의 `title`/`navigation` 필드는 fallback metadata이며
+실제 document title, navigation, loading/error/access surface는
+`route.<ROUTE_ID>.title|navigation` typed catalog key를 해석한다. route params,
+search, backend message를 translation key로 조립하지 않는다. locale 변경은
+현재 route를 재요청하거나 query key를 바꾸지 않고 document title과 화면 copy만
+다시 렌더링한다.
+
+패턴은 추상화 파일만 만든 것으로 완료되지 않는다. reference usage, negative
+architecture test, 실패 상태 test가 있어야 제공된 패턴으로 본다.
+
+## 10. 새 route/page 추가 recipe
+
+1. feature public 경계와 route ID를 정한다.
+2. serializable route contract를 등록한다.
+3. params/search Zod schema와 bidirectional codec을 작성한다.
+4. safe URL builder를 export한다.
+5. lazy page module과 runtime map entry를 추가한다.
+6. session/permission/flag guard를 선언한다.
+7. 적절한 page template을 선택한다.
+8. controller hook을 application input API에 연결한다.
+9. loading, empty, refreshing, error, auth, forbidden, not-found를 결정한다.
+10. title/message key, focus, scroll, chunk ID를 연결한다.
+11. 다음 검증을 추가한다.
+    - contract/runtime map type completeness
+    - codec round-trip/property cases
+    - guard decision unit
+    - page component state
+    - query/mutation integration
+    - keyboard/focus/axe
+    - direct URL, back/forward, refresh E2E
+    - chunk failure recovery가 필요한 route의 E2E
+12. registry, type, architecture, component, integration, E2E gate를 실행한다.
+
+## 11. 금지 패턴
+
+- page 안에서 raw `fetch`, storage, auth SDK, telemetry SDK 호출
+- `useParams()`/`URLSearchParams` 값을 cast만 하고 사용
+- route contract와 JSX route tree를 각각 수동 관리
+- protected route를 server authorization 대체 수단으로 취급
+- 모든 실패를 redirect 또는 full-page error로 처리
+- query data가 있는데 background error 때문에 내용을 제거
+- chunk load error에서 제한 없는 `location.reload`
+- route heading focus outline을 CSS로 무조건 제거
+- template이 data fetching 또는 feature-specific copy를 소유
+- generic `BasePage` prop 하나에 모든 layout variation을 boolean으로 추가
+
+## 12. 완료 기준
+
+- 모든 route ID가 contract와 runtime map에서 compile-time 완전성을 가진다.
+- params/search parse와 URL serialize가 같은 codec을 사용한다.
+- route metadata가 loading/error/chunk/title/navigation 행동에 실제 연결된다.
+- redirect와 chunk reload loop가 차단된다.
+- route 이동 시 query 취소, focus, scroll, dirty policy가 검증된다.
+- collection/detail/form/status reference page가 template을 사용한다.
+- page view가 application input 외의 외부 capability를 직접 호출하지 않는다.
+- 새 route recipe와 테스트만으로 별도 라우터 내부 지식 없이 기능을 추가할 수 있다.

+# Starter experience contract
+
+The repository provides a runnable, domain-neutral application rather than
+only infrastructure contracts. The starter experience is intentionally
+replaceable at the page level while the shell, providers, boundaries,
+primitives, and state surfaces remain reusable.
+
+## Runtime composition
+
+```text
+validated config + coherent release manifest
+  -> concrete adapters
+  -> QueryClientProvider
+  -> ApplicationProvider
+  -> RouterProvider
+  -> ThemeProvider
+  -> SessionProvider
+  -> AppShell
+  -> lazy route boundary
+```
+
+Boot stops before product mount when configuration or release coherence fails.
+Each lazy page renders inside Suspense and a telemetry-aware route boundary.
+Route changes move focus to the new page heading; the skip link and landmarks
+remain stable in the shell.

+
+Navigation labels and order come from `ROUTE_REGISTRY`; the sidebar does not
+maintain a second route list. The client access decision never claims to be
+authorization.
+
+## Authentication seam
+
+The session port exposes state subscription, sign-in start, sign-out,
+credential attachment, recovery, and unauthenticated notification. Credentials
+remain opaque to the application and presentation layers.
+
+- `demo`: local/development-only state transition with no credentials
+- `external`: delegates to `globalThis.__CA_FRONTEND_AUTH_OWNER__`
+- missing/invalid external owner: fails closed as `integration-failed`
+
+An external owner implements `readState`, `subscribe`, `beginSignIn`,
+`signOut`, `attachCredential`, `recoverSession`, and
+`notifyUnauthenticated`. It owns token acquisition and storage.
+
+## Extending the starter
+
+The steps below describe the current extension path. New platform work should follow
+[routing, page templates, and reusable patterns](./routing-pages-and-patterns.md)
+and the
+[TypeScript, state, and data-flow target](./typescript-state-and-data-flow.md)
+rather than adding another independent route or data-loading convention.
+
+1. Add a serializable contribution under the feature ownership boundary and
+   install it through `src/features/installed-feature-contracts.js`.
+2. Add the lazy component and route codecs through
+   `src/features/installed-feature-runtimes.tsx`.
+3. Compose feature application inputs and outbound gateways only through
+   `src/features/installed-feature-adapters.ts`.
+4. Use the semantic tokens, UI primitives, and state surfaces before adding a
+   project-specific variant.
+5. Add component behavior, all-engine E2E, automated axe, and signed manual
+   route evidence.
+6. Run `test:sample-removal` to prove the generic starter typechecks, passes
+   architecture/registry/tests/home smoke, and builds without the complete
+   reference feature.
+
+Theme preference is the public `COLOR_SCHEME` storage contract. Authentication
+tokens and other secrets remain forbidden storage keys.

+# TypeScript, 상태 소유권, 데이터 흐름
+
+## 1. 목적
+
+이 문서는 다음 질문에 대한 저장소 표준을 정의한다.
+
+- JavaScript를 어떤 순서로 TypeScript로 전환하는가.
+- local, URL, server, form, global, persisted 상태를 어디에 둬야 하는가.
+- React 화면이 application use case와 TanStack Query를 어떻게 사용해야 하는가.
+- HTTP, retry, auth, error, validation, logging의 책임을 어떻게 나누는가.
+- 새 query, mutation, form을 추가할 때 어떤 파일과 테스트가 필요한가.
+
+이 문서는 목표 설계다. 현재 구현 상태는
+[프론트엔드 플랫폼 역량 재검토](./frontend-platform-capability-review.md)를 따른다.
+
+## 2. TypeScript 전환 원칙
+
+### 2.1 왜 전환하는가
+
+현재 `strict + allowJs + checkJs`는 JavaScript 상태에서 유용한 안전망이다. 그러나
+JSDoc cast가 늘어나면 다음 계약을 정확히 닫기 어렵다.
+
+- `RouteId`, `OperationId`, `ErrorCode`, `StorageKey`, `TelemetryEvent`
+- `Result<T, E>`와 discriminated failure union
+- use case input/output와 gateway generic
+- route별 params/search type
+- query key tuple
+- component variant와 slot prop
+- runtime registry의 key와 executable implementation의 완전성
+
+TypeScript 전환 목적은 확장자 변경이 아니라 이 계약을 컴파일 단계에서
+검증하는 것이다.
+
+### 2.2 전환 전에 고칠 도구
+
+다음 변경이 첫 브랜치에서 완료되기 전에는 source rename을 시작하지 않는다.
+
+1. ESLint가 `js`, `jsx`, `mjs`, `ts`, `tsx`, `mts`를 모두 검사한다.
+2. React Hooks 규칙을 추가하고 TypeScript/ESLint parser와 JSX accessibility
+   도구는 설치된 compiler/linter의 공식 peer 범위 안에서 선택한다.
+3. dependency-cruiser의 extension과 resolver가 TS/TSX를 포함한다.
+4. `scripts/check-registries.mjs`가 TS/TSX를 검색한다.
+5. `config/contracts/registry-governance.json`의 경로 갱신 절차를 만든다.
+6. Vite, Vitest, Playwright, scripts, source, tests를 각각 typecheck한다.
+7. invalid type fixture가 TS migration 후에도 “실패해야 통과”하는지 확인한다.
+8. architecture/security/registry gate가 TS fixture 위반을 실제로 잡는 negative test를
+   추가한다.
+
+권장 project 구성:
+
+```text
+tsconfig.base.json
+tsconfig.app.json
+tsconfig.node.json
+tsconfig.test.json
+tsconfig.json          # project references only
+```
+
+`tsconfig.base.json`의 초기 핵심 옵션:
+
+```json
+{
+  "compilerOptions": {
+    "strict": true,
+    "noEmit": true,
+    "noUncheckedIndexedAccess": true,
+    "exactOptionalPropertyTypes": true,
+    "useUnknownInCatchVariables": true,
+    "noImplicitOverride": true,
+    "noFallthroughCasesInSwitch": true,
+    "verbatimModuleSyntax": true,
+    "isolatedModules": true
+  }
+}
+```
+
+실제 TypeScript 7/Vite 호환 옵션은 설치된 공식 문서와 빌드 결과를 기준으로
+확정한다. 옵션을 한꺼번에 켜서 수백 개 예외를 만들지 말고, 각 단계에서 새
+예외를 금지한다.
+
+현재 저장소의 VD-01 결정은
+[TypeScript 7과 ESLint 10의 점진적 전환 도구](./decisions/VD-01-typescript-lint-tooling.md)에
+기록돼 있다. app, Node scripts/config, tests는 각각 독립된 project로
+typecheck하며 JS에는 `checkJs`, TS에는 `strict`를 적용한다. TypeScript 7을
+아직 지원하지 않는 parser plugin을 강제 설치하지 않고 Babel parser는 lint
+syntax/import/security 검사, `tsc`는 type semantics를 소유한다.
+
+### 2.3 전환 순서
+
+| 단계 | 대상 | 이유 | 종료 조건 |
+| --- | --- | --- | --- |
+| 0 | lint/typecheck/scanner/architecture tooling | TS 코드가 검사를 우회하지 않게 함 | TS 위반 fixture가 각 게이트에서 실패 |
+| 1 | result, failure, ID, registry types | 이후 모든 계층의 언어가 됨 | stringly typed public ID 제거 |
+| 2 | application input/output ports와 use case | 중심 계약을 먼저 고정 | input/output compile fixture 통과 |
+| 3 | domain model과 mapper boundary | DTO와 core model 혼합 차단 | mapper contract test 통과 |
+| 4 | outbound adapters | 외부 `unknown`을 경계에서 좁힘 | HTTP/storage/auth failure type 통과 |
+| 5 | bootstrap/composition | 누락 dependency를 컴파일로 검출 | 실제 composition type test 통과 |
+| 6 | React providers/controllers/routes | typed application API 소비 | route/runtime map 완전성 검사 |
+| 7 | primitives/pages/templates | component API와 variant를 닫음 | stories/component tests typecheck |
+| 8 | tests/scripts/config | 우회 없는 전체 저장소 | source `allowJs` 제거 가능 |
+
+각 단계는 빌드 가능한 작은 커밋으로 유지한다. JavaScript와 TypeScript가 공존하는
+동안에는 [공식 JavaScript migration 가이드](https://www.typescriptlang.org/docs/handbook/migrating-from-javascript.html)의
+점진적 방식을 사용한다.
+
+### 2.4 기본 type 계약
+
+다음 형태를 core application에 둔다.
+
+```ts
+export type Ok<T> = Readonly<{ ok: true; value: T }>;
+export type Err<E> = Readonly<{ ok: false; error: E }>;
+export type Result<T, E> = Ok<T> | Err<E>;
+
+export type AppFailure =
+  | Readonly<{ kind: "unauthenticated"; code: "AUTH_REQUIRED"; traceId?: string }>
+  | Readonly<{ kind: "forbidden"; code: "FORBIDDEN"; traceId?: string }>
+  | Readonly<{ kind: "not-found"; code: "NOT_FOUND"; traceId?: string }>
+  | Readonly<{ kind: "conflict"; code: "CONFLICT"; traceId?: string }>
+  | Readonly<{
+      kind: "validation";
+      code: "VALIDATION_FAILED";
+      fields: Readonly<Record<string, readonly string[]>>;
+      traceId?: string;
+    }>
+  | Readonly<{ kind: "rate-limited"; code: "RATE_LIMITED"; retryAt?: Date }>
+  | Readonly<{ kind: "unavailable"; code: "UNAVAILABLE"; retryable: boolean }>
+  | Readonly<{ kind: "unexpected"; code: "UNEXPECTED"; traceId?: string }>;
+```
+
+원칙:
+
+- adapter에서 받은 `unknown`은 adapter 경계에서 parse한다.
+- application은 `Response`, `AxiosError`, Zod 내부 오류 같은 vendor type을
+  노출하지 않는다.
+- UI copy는 failure에 저장하지 않고 message key mapper에서 결정한다.
+- 예상 가능한 실패는 `Result`; programmer bug와 render crash는 error boundary로
+  보낸다.
+- `as`, non-null assertion, `any`는 경계에서 근거가 있을 때만 사용하고 lint
+  예외에 사유를 기록한다.
+
+## 3. 상태 소유권
+
+### 3.1 상태 분류표
+
+상태를 만들기 전에 아래 순서로 소유자를 결정한다.
+
+| 질문 | 상태 종류 | 기본 도구 | 저장 위치 |
+| --- | --- | --- | --- |
+| 한 컴포넌트 상호작용에만 필요한가 | local UI | `useState`, `useReducer` | component/controller |
+| URL로 공유·복원되어야 하는가 | navigation | router params/search + codec | URL |
+| 서버가 진실의 원천인가 | server state | TanStack Query inbound adapter | Query cache |
+| 입력 중이고 제출 전인가 | form | local form facade | form controller |
+| 앱 전체에서 낮은 빈도로 바뀌는가 | cross-cutting | Context 또는 typed external store | provider/store |
+| 여러 feature의 복잡한 workflow인가 | client workflow | reducer, Zustand, Redux Toolkit, state machine | feature-owned store |
+| 새로고침 후 남아야 하는가 | persisted preference | `StoragePort` | versioned browser storage |
+| 인증 credential인가 | auth secret | external auth owner | SDK memory 또는 HttpOnly cookie |
+
+금지:
+
+- server response를 global client store에 복사하지 않는다.
+- URL에 있어야 할 filter/sort/page를 숨은 store에만 두지 않는다.
+- component 내부에 머물 수 있는 modal open 상태를 전역화하지 않는다.
+- access token을 localStorage, sessionStorage, 일반 Redux/Zustand store에 넣지
+  않는다.
+- 모든 상태를 추상화하는 범용 `StorePort`를 만들지 않는다.
+
+### 3.2 범용 store 선택 기준
+
+기본 skeleton에는 빈 Zustand/Redux store를 만들지 않는다. 실제 요구가 생기면
+다음 기준을 적용한다.
+
+| 조건 | 권장 |
+| --- | --- |
+| feature 한 곳의 단순 shared client state | feature reducer 또는 작은 Zustand store |
+| 여러 팀이 action/state 규약, devtools, middleware, audit를 공유 | Redux Toolkit |
+| 명시적 상태 전이, 병렬 상태, 취소/보상 workflow | state machine |
+| session/theme처럼 저빈도 cross-cutting | `useSyncExternalStore` 또는 Context |
+
+vendor를 선택하더라도 feature 외부에는 hook/facade만 export한다. 제품 코드가
+store instance의 `getState`와 `setState`를 임의 호출하지 않게 한다.
+
+### 3.3 persistence
+
+persisted state는 다음 metadata를 가져야 한다.
+
+```ts
+type PersistedRecord<T> = Readonly<{
+  version: number;
+  writtenAt: string;
+  value: T;
+}>;
+```
+
+- key는 typed registry가 소유한다.
+- read 시 schema parse와 migration을 거친다.
+- quota, unavailable, corrupt, version mismatch를 구분한다.
+- 민감정보와 credential을 저장하지 않는다.
+- server state persistence와 offline mutation queue는 별도 project-selected
+  adapter다.
+
+## 4. 표준 데이터 호출 경로
+
+```mermaid
+sequenceDiagram
+  actor User
+  participant Page as React page
+  participant Controller as inbound query/mutation controller
+  participant App as application input use case
+  participant Gateway as output gateway
+  participant Adapter as HTTP/generated client adapter
+  participant API as Backend/BFF
+
+  User->>Page: route or event
+  Page->>Controller: typed input
+  Controller->>App: query/command + AbortSignal
+  App->>Gateway: capability request
+  Gateway->>Adapter: DTO request
+  Adapter->>API: path/query/body/auth
+  API-->>Adapter: envelope or failure
+  Adapter-->>Gateway: parsed DTO Result
+  Gateway-->>App: mapped model Result
+  App-->>Controller: view data or AppFailure
+  Controller-->>Page: query/mutation state
+```
+
+페이지는 controller hook이 제공하는 상태만 렌더링한다. controller는 React,
+TanStack Query와 application input interface를 알 수 있지만 use case의 concrete
+구현과 outbound adapter는 모른다.
+
+### 4.1 Application API
+
+```ts
+export interface Application {
+  readonly resources: {
+    list(
+      input: ListResourcesInput,
+      context: Readonly<{ signal: AbortSignal }>,
+    ): Promise<Result<readonly ResourceSummary[], AppFailure>>;
+    create(
+      command: CreateResourceCommand,
+      context?: Readonly<{ signal?: AbortSignal }>,
+    ): Promise<Result<Resource, AppFailure>>;
+  };
+}
+```
+
+`ApplicationProvider`는 이 API를 immutable value로 제공한다. controller 외의
+presentation 코드에서 raw HTTP/storage/telemetry port를 가져오는 hook은 만들지
+않는다. theme, locale 같은 UI platform provider는 별도다.
+
+### 4.2 query adapter
+
+```ts
+export function useResourcesQuery(input: ListResourcesInput) {
+  const application = useApplication();
+
+  return useQuery({
+    queryKey: resourceKeys.list(input),
+    queryFn: async ({ signal }) =>
+      unwrapResult(await application.resources.list(input, { signal })),
+    retry: false,
+    staleTime: resourceQueryPolicy.list.staleTime,
+  });
+}
+```
+
+실제 구현 규칙:
+
+- query key는 readonly tuple factory로만 만든다.
+- key에 들어간 filter는 실제 gateway request에도 동일하게 투영한다.
+- `AbortSignal`을 application과 HTTP transport까지 전달한다.
+- HTTP 계층이 bounded retry를 소유하면 query retry는 끈다.
+- background error와 initial error의 UI를 구분한다.
+- placeholder와 cached stale data가 있을 때 전체 화면 error로 교체하지 않는다.
+- `select`는 view-only projection에 쓰고 도메인 규칙을 넣지 않는다.
+- query hook은 feature public API에서 export한다.
+
+### 4.3 mutation adapter
+
+```ts
+export function useCreateResourceMutation() {
+  const application = useApplication();
+  const queryClient = useQueryClient();
+
+  return useMutation({
+    mutationFn: (command: CreateResourceCommand) =>
+      application.resources.create(command).then(unwrapResult),
+    onSuccess: () =>
+      queryClient.invalidateQueries({ queryKey: resourceKeys.all }),
+  });
+}
+```
+
+기본 mutation은 navigation만으로 취소됐다고 가정하지 않는다. 서버 작업의 취소가
+안전한 operation만 controller가 보관한 `AbortController`와 명시적 cancel action을
+사용한다. idempotency key는 UI 입력으로 받지 않고 application use case가
+`IdGeneratorPort`로 만들며, 같은 논리 요청의 bounded HTTP retry와 auth replay는
+동일한 key를 재사용한다.
+
+실제 구현에서는 mutation마다 다음을 명시한다.
+
+- double-submit 방지와 idempotency key 소유자
+- cancel 가능 여부
+- optimistic update 적용 여부와 rollback snapshot
+- 성공 후 invalidate/update/navigation 순서
+- 409 conflict와 422 field validation mapping
+- offline 시 queue할지 즉시 실패할지
+- analytics/telemetry event와 redaction
+
+optimistic update는 기본값이 아니다. 서버 규칙을 확실히 재현할 수 있고 rollback이
+안전한 mutation에만 사용한다.
+
+## 5. HTTP client 책임
+
+### 5.1 목표 파이프라인
+
+```text
+operation registry
+  -> path/search/body builder
+  -> credential attachment
+  -> timeout and external cancellation
+  -> bounded retry
+  -> fetch transport
+  -> status/envelope decoder
+  -> response schema decoder
+  -> feature DTO mapper
+  -> AppFailure mapper
+```
+
+각 단계의 입력과 출력은 typed result다. feature-specific model mapper를 공통 HTTP
+client 안에 넣지 않는다.
+
+### 5.2 request projection
+
+operation definition은 최소 다음 계약을 갖는다.
+
+```ts
+type OperationDefinition<
+  TPath,
+  TSearch,
+  TBody,
+  TResponse,
+> = Readonly<{
+  id: OperationId;
+  method: HttpMethod;
+  pathTemplate: string;
+  pathSchema: Schema<TPath>;
+  searchSchema: Schema<TSearch>;
+  bodySchema: Schema<TBody>;
+  responseSchema: Schema<TResponse>;
+  timeoutMs?: number;
+  retryClass: "never" | "safe" | "idempotency-keyed";
+}>;
+```
+
+규칙:
+
+- path segment는 `encodeURIComponent`에 해당하는 안전한 builder를 통과한다.
+- query의 array/null/undefined/boolean/date serialization을 한 곳에서 정의한다.
+- Zod parse 결과의 trim/default/coercion을 실제 request에 사용한다.
+- GET/HEAD에는 body를 보내지 않는다.
+- JSON content type은 body가 있을 때만 붙인다.
+- base URL과 path를 문자열 덧붙이기로 조립하지 않는다.
+- external URL은 별도 allowlist policy를 거친다.
+
+### 5.3 timeout, cancellation, retry
+
+소유권:
+
+- 사용자 navigation/unmount 취소: query/controller가 signal 생성
+- operation timeout: HTTP adapter
+- retry: HTTP adapter 또는 query adapter 중 하나
+- 인증 복구 후 단 한 번 replay: auth decorator
+- mutation idempotency: application/controller가 key 생성, operation이 허용 여부 선언
+
+retry 조건:
+
+- safe method 또는 idempotency key가 있는 허용 operation만 대상
+- timeout, network, 명시된 429/5xx만 정책 대상
+- validation, auth denial, forbidden, not found, conflict는 자동 재시도하지 않음
+- `Retry-After`와 bounded exponential backoff/jitter 지원
+- tab hidden/offline 상태를 고려
+- 최대 횟수와 전체 elapsed budget을 함께 제한
+- 각 attempt와 final failure를 redacted telemetry로 기록
+
+timer와 event listener는 성공, 실패, validation 조기 반환, external abort 모든
+경로에서 정리되어야 한다.
+
+RP-03의 현재 구현은 다음 계약을 자동 검증한다.
+
+- `request-builder.ts`가 path 값을 escape하고 search key를 정렬하며 array 순서를
+  보존한다.
+- operation의 `requestSource`가 search/body schema를 선택하고 Zod의
+  default/trim 결과만 URL 또는 JSON payload에 전달한다.
+- runtime `REQUEST_TIMEOUT_MS`와 `MAX_RETRY_ATTEMPTS`가 transport factory에
+  주입된다.
+- query adapter의 자동 retry는 끄고 HTTP만 bounded network retry를 소유한다.
+- `AsyncOverlay`는 refreshing/stale-degraded/mutation-pending/
+  mutation-conflict를 TypeScript union으로 배타화한다.
+- `useApplicationQuery`와 `useApplicationMutation`은 cancellation, stale latch,
+  duplicate submit, optimistic rollback, conflict resolution을 제공한다.
+
+## 6. 인증과 token 소유권
+
+기본 skeleton은 token manager를 제공하지 않는다.
+
+지원 profile:
+
+| profile | credential 소유자 | frontend 역할 |
+| --- | --- | --- |
+| BFF/HttpOnly cookie | browser cookie + backend | `credentials`, CSRF 정책, session probe |
+| external OIDC/Auth SDK | SDK memory/cache | attach/recover/login/logout를 auth adapter로 감쌈 |
+| SPA memory token | auth adapter memory | 프로젝트가 명시적으로 선택할 때만 |
+
+공통 `AuthSessionReader`와 HTTP 전용 `CredentialProvider`를 분리한다.
+
+```ts
+interface AuthSessionReader {
+  getSnapshot(): SessionSnapshot;
+  subscribe(listener: () => void): () => void;
+}
+
+interface CredentialProvider {
+  attach(request: RequestInit): Promise<RequestInit>;
+  recover(failure: AuthFailure): Promise<"recovered" | "not-recovered">;
+}
+```
+
+UI는 credential을 읽지 않는다. HTTP adapter는 UI session action을 호출하지
+않는다. logout/login/redirect는 application input 또는 auth UI facade를 통해
+실행한다.
+
+## 7. 오류, 검증, logging
+
+### 7.1 검증 계층
+
+| 경계 | 책임 | 예 |
+| --- | --- | --- |
+| runtime config | 앱을 안전하게 시작할 수 있는가 | URL, timeout, auth mode |
+| route codec | URL을 typed input으로 읽고 쓸 수 있는가 | page, sort, ID |
+| transport DTO | 외부 응답/요청 형식이 계약과 맞는가 | envelope, date string |
+| form | 사용자가 수정 가능한 입력 형태가 유효한가 | required, length, format |
+| application | use case precondition이 맞는가 | command 조합 |
+| domain | 항상 지켜야 할 불변식인가 | valid state transition |
+
+같은 Zod schema를 무조건 모든 계층에서 재사용하지 않는다. transport DTO, form
+value, application command, domain model이 우연히 같은 모양이어도 소유권과
+변경 이유가 다르다. 필요한 경우 mapper로 연결한다.
+
+### 7.2 사용자 오류 표면
+
+`AppFailure`를 다음 UI 상태로 매핑한다.
+
+| failure | 기본 표면 | 자동 행동 |
+| --- | --- | --- |
+| unauthenticated | auth required 또는 login transition | auth policy에 따른 1회 복구 |
+| forbidden | 권한 없음 | 없음 |
+| not-found | route/detail not-found | 없음 |
+| validation | error summary + field errors | 첫 오류 focus |
+| conflict | 현재 데이터 유지 + conflict action | 자동 overwrite 금지 |
+| rate-limited | inline retry time | 허용된 query만 지연 재시도 |
+| unavailable | cached data 또는 retry surface | policy 범위 내 retry |
+| unexpected | safe generic copy + trace ID | diagnostics emit |
+
+raw response body, stack, token, URL query, PII를 사용자 copy나 일반 log에 노출하지
+않는다.
+
+### 7.3 diagnostics와 telemetry
+
+현재 telemetry event contract와 별도로 개발·진단용 structured logger가 필요하다.
+다음 두 설계 중 하나를 ADR로 결정한다.
+
+1. `DiagnosticsPort`가 log/event/span을 내부 method로 구분
+2. `LoggerPort`와 `TelemetryPort`를 분리
+
+공통 요구:
+
+- log level과 event key는 닫힌 union
+- attribute allowlist와 중앙 redaction
+- dev adapter는 console을 사용하되 동일 redaction 적용
+- production adapter는 provider SDK를 감싸며 앱 코드는 SDK를 import하지 않음
+- 오류 객체 전체를 그대로 serialize하지 않음
+- trace ID/build ID/route ID/operation ID를 허용된 범위에서 연결
+- logging failure가 제품 flow를 실패시키지 않음
+- consent가 필요한 analytics와 essential diagnostics를 분리
+
+### 7.4 locale, message와 표시 값
+
+RP-08부터 locale은 presentation-owned React context다. server/application
+state에 번역된 문자열을 저장하거나 query key에 locale을 넣는 것은 응답 자체가
+locale별 데이터인 경우에만 허용한다. 공통 UI copy 변경 때문에 query cache를
+복제하지 않는다.
+
+```text
+API timestamp/number/failure kind
+  -> schema + mapper (의미 값 유지)
+  -> application result
+  -> presentation controller
+  -> useLocale().date/number/message
+```
+
+- message key는 `MessageKey` union이며 interpolation은 key별 tuple type이다.
+- unknown external key는 `resolveMessage`에 전달해도 raw key가 표시되지 않는다.
+- backend `message`는 diagnostic input일 수 있지만 사용자 copy가 아니다.
+- form validation code는 `ParameterlessMessageKey` allowlist로 mapping한다.
+- date의 기본 timezone은 UTC이고 제품 timezone은 presentation 호출자가
+  명시한다.
+- pseudo/RTL locale state는 local interaction state이며 persistence와 server
+  synchronization을 기본 제공하지 않는다.
+- key rename은 typed canonical key를 먼저 이동하고 runtime alias에 migration
+  기간을 둔다.
+
+## 8. 폼 표준
+
+VD-04에 따라 현재 기본 엔진은 React native form event와 controlled value이며
+Zod를 local facade 뒤에서 사용한다. 동적 field array, 비동기 field validation,
+대규모 render isolation 요구가 실제로 생기면 public API를 유지한 채 React Hook
+Form 또는 TanStack Form adapter를 평가한다.
+
+현재 public API는 다음과 같다.
+
+- `Form`
+- `FormField`
+- `Label`
+- `Description`
+- `FieldError`
+- `ErrorSummary`
+- `useAppForm`
+- `mapValidationFailureToFields`
+- `useDirtyNavigationGuard`
+
+구현 위치:
+
+- controller와 mapping: `src/presentation/forms`
+- layout-only template: `src/presentation/templates`
+- feature form schema/command mapper:
+  `src/features/reference-feature/presentation/reference-resource-form.ts`
+- 실제 create page:
+  `src/features/reference-feature/presentation/reference-resource-form-page.tsx`
+
+`ApiFailure.validationIssues`는 HTTP 경계가 투영한 `path`와 `code`만 담는다.
+backend message와 알 수 없는 path는 field copy로 사용하지 않는다.
+
+필수 동작:
+
+1. label, description, error를 stable ID와 `aria-describedby`로 연결
+2. submit 시 error summary와 첫 오류 focus
+3. submitting 중 중복 제출 방지

+soft-fail wiring.
+
+The dependency graph is:

+```text
+MERGE_READY
+  -> RELEASE_READY
+    -> PROD_PROMOTION_READY
+      -> FIELD_SLO_READY
+
+DOCUMENTATION_READY (off-chain)

+
+Pull requests and `develop` pushes evaluate merge readiness. Version tags
+evaluate merge then release readiness. Production and field evaluation require
+an explicit workflow dispatch. The field tier cannot pass until the 28-day
+sample threshold decision is recorded. Documentation readiness consumes the
+canonical project-note evidence in which both scoped diagrams already received
+100/100 `PASS_SCOPED`; the repo ledger preserves the evidence scope and
+canonical digests.
+
+All jobs upload the shared `artifacts/` tree even after failure. Numeric
+retention remains an organization/provider decision; the workflow intentionally
+does not invent `retention-days`. The relative minimums are recorded in the
+registry: merge evidence through the PR decision, coherent release evidence
+through the next release promotion, drill evidence through the next production
+promotion, and field evidence through aggregation.
+
+Browser-backed merge gates install and execute the pinned Chromium, Firefox,

+than a Chromium-only smoke check.

+# Release, cache, and rollback contract
+
+Each deployment is an immutable `releases/<releaseId>/` artifact set. The
+provider adapter must upload assets, release manifest, runtime config, and
+verify asset reachability before atomically switching the active HTML pointer.
+The post-switch boot, route, API, telemetry, and reload-loop smoke checks close
+the deployment.
+
+Rollback selects a prior release tuple, confirms its assets and runtime/API
+compatibility, atomically switches the complete set, performs the provider
+cache action, and repeats the smoke checks. Rebuilding an old commit, replacing
+HTML alone, or declaring recovery from cache-purge completion is prohibited.
+Recovery is established by old/new reachability probes.

+- hashed assets: `public, max-age=31536000, immutable`
+- HTML: `no-cache`
+- runtime config and release manifest: `no-store`
+- public source maps: disabled
+- service worker/offline cache: disabled
+
+HTML, JSON config/manifest, and hashed JavaScript MIME types are also compared
+to the declared allowlist; a cache-correct response with a mismatched
+`Content-Type` still fails the hosting gate.

+`corepack pnpm verify:hosting-headers` uses a deterministic fixture locally.
+Set `HOSTING_BASE_URL` to probe deployed responses; production promotion
+requires the artifact to report `mode: "live"`. The live target must be its

+# 디자인 시스템 플랫폼 계약
+
+이 문서는 도메인 기능을 추가하기 전에 프론트엔드 스켈레톤이 제공해야 하는
+디자인 시스템의 소유권, 계층, 기본 구성요소, 외부 라이브러리 경계, 검증 방법을
+정의한다. 목표는 특정 제품의 시각 언어를 미리 결정하는 것이 아니라, 제품 팀이
+접근성·반응형·국제화·테스트 규칙을 다시 발명하지 않고 기능 화면을 만들 수 있게
+하는 것이다.
+
+이 문서에서 `필수`는 모든 제품이 기반으로 사용할 계약을 뜻한다. `선택`은
+컴포넌트의 경계와 도입 기준은 제공하지만 실제 의존성이나 구현은 제품 요구가
+생긴 뒤 추가해도 되는 항목을 뜻한다.
+
+## 1. 현재 기준선과 확인된 공백
+
+현재 저장소에는 다음 기반이 이미 있다.
+
+- `src/presentation/styles/theme.css`
+  - 의미 기반 light/dark 색상 토큰
+  - focus indicator
+  - 반응형 앱 셸
+  - reduced-motion 처리
+- `src/presentation/providers/theme-provider.jsx`
+  - `system`, `light`, `dark` 선호도
+  - 저장소 포트를 통한 선호도 영속화
+  - 운영체제 색상 변경 구독
+- `src/presentation/components/ui/`
+  - `Button`
+  - `TextField`
+  - `Card`
+  - `Alert`
+  - `Badge`
+  - `Dialog`
+- `src/presentation/components/async-surface.jsx`
+  - 초기 로딩, 빈 화면, terminal error, background 상태
+- `src/presentation/components/state-surfaces.jsx`
+  - 인증 필요, 권한 없음, 찾을 수 없음
+- `src/presentation/forms`
+  - local form facade, field/error summary, dirty navigation dialog
+- `src/presentation/templates`
+  - Standard, Collection, Detail, Form, Status page template
+- `/examples/ui`, `/examples/states`
+  - 실행 가능한 primitive와 상태 예제
+- component/E2E/axe 테스트
+  - 필드 설명과 오류 연결
+  - native dialog 닫기와 trigger focus 복원
+  - 320px reflow
+  - Chromium, Firefox, WebKit
+  - 등록 라우트의 자동 접근성 검사
+
+RP-07 구현 이후 이 기반은 저장소 내부 디자인 시스템 플랫폼 계약을 충족한다.
+아래 목록은 구현 전 공백과 현재 해결 상태를 함께 보존한다.
+
+1. typography, elevation, motion, z-layer, control size와 breakpoint는
+   `design-system/tokens`의 3계층과 자동 gate로 닫혔다.
+2. RP-06 form/page foundation은 준비됐지만 TextArea, Select, Checkbox,
+   RadioGroup 같은 form primitive 확장은 RP-07에 남아 있다.
+3. 앱 셸, 예제와 reference feature는 public design-system barrel을 소비한다.
+4. 문자 glyph는 semantic Lucide facade로 교체됐다.
+5. token은 세 CSS 파일로 분리됐고 `theme.css`는 layout/component styling만
+   소유한다.
+6. runtime gallery는 있지만 격리된 story, interaction story, 시각 회귀 기준선이
+   없다.
+7. 사용자 문구가 한국어 literal로 고정되어 locale과 RTL 계약이 없다.
+8. page template, form과 pattern은 public barrel에서 제공된다.
+9. 모바일 navigation은 native modal Drawer로 focus 이동, 배경 비활성화,
+   Escape/link dismiss와 trigger focus restore를 제공한다.
+
+따라서 기존 구성요소는 폐기하지 않고 아래 목표 계층으로 이동·확장한다.
+
+## 2. 소유권과 의존성 원칙
+
+디자인 시스템은 `presentation` 계층이 소유한다. 색상, 아이콘, 키보드 상호작용,
+포커스, 화면 배치와 같은 문제는 도메인 규칙이 아니다.
+
+```text
+product page
+  -> template
+  -> pattern
+  -> primitive
+  -> token
+```
+
+외부 UI 라이브러리를 사용하는 경우 흐름은 다음과 같다.
+
+```text
+product page
+  -> local design-system API
+  -> local vendor facade
+  -> Lucide / React Aria / Radix
+```
+
+다음 규칙은 필수다.
+
+- 제품 페이지는 `lucide-react`, `react-aria-components`, `@radix-ui/*`를 직접
+  import하지 않는다.
+- 외부 UI 라이브러리 type을 공용 컴포넌트 API로 그대로 노출하지 않는다.
+- 도메인과 application 계층은 React component, CSS class, icon name을 알지
+  않는다.
+- primitive는 API 요청, query cache, 인증 상태와 같은 외부 상태를 직접 읽지
+  않는다.
+- pattern과 template도 application use case를 직접 선택하지 않는다. 필요한
+  상태와 command callback을 props/slot으로 받는다.
+- 제품별 색상이나 명칭을 primitive 내부에 하드코딩하지 않는다.
+- 같은 의미의 접근성·키보드 동작을 페이지마다 다시 구현하지 않는다.
+- 세 번째 사용 사례가 확인되기 전에는 제품 전용 조합을 무리하게 primitive로
+  승격하지 않는다.
+
+아이콘과 headless UI는 React inbound adapter의 vendor facade로 충분하다.
+이들을 위한 application port를 만들지 않는다. HTTP, storage, telemetry처럼
+런타임 외부 자원을 교체하는 capability와 UI 구현 라이브러리를 구분한다.
+
+## 3. 목표 디렉터리
+
+TypeScript 전환 이후의 목표 구조는 다음과 같다. 마이그레이션 중에는 기존
+경로에서 같은 소유권 규칙을 지키고, 한 번에 전체 경로를 이동하지 않아도 된다.
+
+```text
+src/adapters/inbound/react/design-system/
+  index.ts
+  tokens/
+    primitive.css
+    semantic.css
+    component.css
+    token-contract.ts
+  primitives/
+    button/
+    field/
+    checkbox/
+    dialog/
+    ...
+  patterns/
+    async-surface/
+    form/
+    data-table/
+    confirmation/
+    ...
+  templates/
+    standard-page/
+    collection-page/
+    detail-page/
+    form-page/
+    status-page/
+  icons/
+    icon.tsx
+    icon-button.tsx
+    semantic-icons.tsx
+    vendors/
+      lucide.tsx
+  vendors/
+    react-aria/
+  testing/
+    story-decorators.tsx
+    render-design-system.tsx
+```
+
+`index.ts`는 제품의 React inbound 코드가 사용할 public API다. 내부 파일 deep
+import는 디자인 시스템 자체와 테스트에만 허용한다. 이 경계는 ESLint의
+`no-restricted-imports`로 검사한다.
+
+현재 `src/presentation`은 React inbound adapter 역할을 한다. TypeScript
+마이그레이션 동안 기존 경로를 유지할 수 있지만, 최종 canonical target은 위
+경로다. 같은 컴포넌트를 `presentation`과 `adapters/inbound/react` 양쪽에
+복제하지 않고 feature 단위로 이동한다.
+
+## 4. 계층 계약
+
+### 4.1 Tokens
+
+토큰은 시각적 결정을 이름으로 표현한다. 토큰은 세 계층으로 관리한다.
+
+```text
+primitive token -> semantic token -> component token
+```
+
+예:
+
+```css
+--palette-blue-600: ...;
+--color-action: var(--palette-blue-600);
+--button-primary-background: var(--color-action);
+```
+
+#### Primitive tokens
+
+원시 palette와 scale이다. 제품 코드에서 직접 소비하지 않는다.
+
+- palette
+- spacing scale
+- font size와 line height scale
+- radius scale
+- shadow scale
+- duration과 easing scale
+- fixed size scale
+
+#### Semantic tokens
+
+제품 코드와 대부분의 primitive가 소비하는 이름이다.
+
+- `surface`, `surface-muted`, `surface-elevated`
+- `content`, `content-muted`, `content-inverse`
+- `border`, `border-strong`
+- `action`, `action-hover`, `action-pressed`
+- `danger`, `warning`, `success`, `info`
+- `focus-ring`
+- `disabled-content`, `disabled-surface`
+
+#### Component tokens
+
+특정 primitive가 여러 semantic token을 조합할 때만 사용한다.
+
+- `button-primary-background`
+- `field-border-invalid`
+- `dialog-elevation`
+- `navigation-active-background`
+
+컴포넌트 토큰은 제품별 variant를 만들기 위한 우회 경로가 아니다. 두 개 이상의
+컴포넌트가 같은 의미를 공유한다면 semantic token으로 승격한다.
+
+#### 필수 토큰 범주
+
+| 범주 | 필수 내용 |
+| --- | --- |
+| Color | surface/content/border/action/status/focus, light/dark |
+| Typography | family, size, line-height, weight, letter-spacing |
+| Spacing | inset, inline, stack, section, page spacing scale |
+| Size | control height, icon size, touch target, container width |
+| Border | width, style, semantic border |
+| Radius | control, surface, modal, full |
+| Elevation | panel, popover, dialog, sticky shell |
+| Z-layer | base, sticky, navigation, popover, modal, toast |
+| Motion | fast/normal/slow duration, standard/emphasized easing |
+| Breakpoint | compact, medium, wide와 container 계약 |
+| Opacity | disabled, scrim, skeleton |
+
+토큰의 완료 조건은 다음과 같다.
+
+- light와 dark에서 모든 semantic token이 정의된다.
+- `forced-colors`에서도 focus와 control 경계가 사라지지 않는다.
+- 상태는 색상만으로 구분하지 않는다.
+- 같은 raw value가 반복되면 named token으로 승격한다.
+- 사용자 입력으로 CSS class나 CSS variable 이름을 조립하지 않는다.
+- token contract test가 필수 token의 누락을 차단한다.
+- chart나 canvas처럼 JavaScript 값이 필요한 경우에만 typed token accessor를
+  제공한다.
+
+## 5. 기본 컴포넌트 카탈로그
+
+### 5.1 Primitives
+
+Primitive는 하나의 접근 가능한 상호작용 또는 작은 시각 단위를 제공한다.
+
+| 그룹 | 기본 제공 | 우선순위 | 핵심 계약 |
+| --- | --- | --- | --- |
+| Action | `Button` | 필수 | intent, size, disabled, pending, native semantics |
+| Action | `LinkButton` | 필수 | navigation은 anchor/router link semantics 유지 |

+| Feedback | `Spinner` | 필수 | accessible label 또는 decorative |
+| Feedback | `ProgressBar` | 필수 | determinate/indeterminate |
+| Feedback | `Skeleton` | 필수 | 실제 layout과 유사한 크기, reduced motion |
+| Feedback | `Toast` | 필수 | queue, 중복 방지, timeout pause |

+| Overlay | `Tooltip` | 필수 | hover와 keyboard, 중요한 정보 단독 보유 금지 |
+| Overlay | `Menu` | 필수 | roving focus, typeahead, Escape |
+| Navigation | `Breadcrumbs` | 필수 | 현재 위치와 overflow |
+| Navigation | `Tabs` | 필수 | manual/automatic activation 정책 |
+| Navigation | `Pagination` | 필수 | current page, previous/next label |
+| Utility | `VisuallyHidden` | 필수 | screen-reader-only content |

+| Utility | `FocusRing` | 필수 | input modality 인식 |
+| Advanced | date/time picker | 선택 | locale/time zone 요구가 있을 때 |
+| Advanced | file upload/dropzone | 선택 | upload adapter 요구가 있을 때 |
+| Advanced | virtualizer/tree | 선택 | 실제 데이터 규모가 입증될 때 |
+
+Primitive API는 다음 규칙을 지킨다.
+
+- 기본 HTML semantics를 보존한다.
+- `div onClick`로 button이나 link를 흉내 내지 않는다.
+- `variant`, `size`, `tone`은 closed union과 정적 class map을 사용한다.
+- pending은 focus를 잃게 하는 무조건적인 `disabled`와 구분한다.
+- controlled와 uncontrolled 지원 여부를 문서화한다.
+- ref 전달과 focus contract를 테스트한다.
+- `className`은 escape hatch이지 public variant를 대체하지 않는다.
+- 임의의 polymorphic `as`보다 `Button`과 `LinkButton`처럼 semantics가 명확한
+  API를 우선한다.
+- visual-only prop이 도메인 의미를 표현하지 않도록 한다.
+
+### 5.2 Patterns
+
+Pattern은 여러 primitive를 조합해 반복되는 사용자 문제를 해결한다.
+
+| Pattern | 필수 내용 |
+| --- | --- |
+| `AsyncSurface` | loading, success, empty, terminal error, stale, refresh |
+| `AccessSurface` | auth required, forbidden, not found |
+| `Form` | submit, error summary, first-invalid focus, pending |
+| `ConfirmationDialog` | destructive action 설명과 명시적 확인 |
+| `ToastRegion` | queue, announcement, dismiss, focus policy |
+| `SearchFilterToolbar` | search, filter, reset, result count |
+| `DataTable` | caption, sorting, selection, responsive fallback |
+| `PaginationBar` | result range와 page navigation |
+| `NavigationDrawer` | mobile focus scope와 background inert |
+| `DisclosureGroup` | help/settings section |
+
+Pattern은 application failure object 전체를 렌더링하지 않는다. 안전한 message key,
+사용자 action, 표시 가능한 metadata만 받는다.
+
+### 5.3 Templates
+
+Template은 페이지 레이아웃과 상태 slot을 제공한다. API 호출과 도메인 use case는
+소유하지 않는다.
+
+#### `StandardPageTemplate`
+
+- breadcrumb 또는 back navigation
+- eyebrow
+- `h1`
+- description
+- status/metadata
+- primary/secondary actions
+- main content와 aside slot
+
+#### `CollectionPageTemplate`
+
+- page header
+- search/filter/sort toolbar
+- result count

+#### `DetailPageTemplate`
+
+- breadcrumb/back

+고정한다. 다만 `Card` 같은 하위 primitive가 무조건 `h3`를 생성해서도 안 된다.
+
+## 6. Lucide 아이콘 facade
+
+[Lucide for React 공식 문서](https://lucide.dev/guide/react)는 각 아이콘을 독립
+React component로 제공하며 명시적으로 import한 아이콘만 번들에 포함될 수 있는
+tree-shaking 구조를 제공한다. 기본 아이콘 공급자로 사용하기에 적합하지만 제품
+코드가 공급자 API에 결합되면 안 된다.
+
+### 6.1 필수 규칙
+
+1. `lucide-react` import는 `icons/vendors/lucide.tsx`에서만 허용한다.
+2. 제품 코드에는 Lucide component type, icon name, stroke prop을 노출하지 않는다.
+3. 디자인 시스템이 승인한 작은 아이콘 집합만 명시적으로 import한다.
+4. 모든 아이콘을 이름으로 동적 import하는 범용 `DynamicIcon`은 기본 제공하지
+   않는다.
+5. 아이콘 색은 기본적으로 `currentColor`를 사용한다.
+6. 크기와 stroke는 `--icon-size-*`, `--icon-stroke-*` 토큰을 사용한다.
+7. 장식 아이콘은 기본적으로 `aria-hidden="true"`와 `focusable="false"`다.
+8. 정보를 단독으로 전달하는 아이콘은 local `Icon` API의 `label`을 통해
+   `role="img"`와 accessible name을 가진다.
+9. 버튼 안의 아이콘은 장식으로 처리하고 버튼 자체에 visible label 또는
+   `aria-label`을 둔다.
+10. 상태를 아이콘이나 색상 하나만으로 전달하지 않는다.
+
+### 6.2 목표 API 예시
+
+아래 예시는 방향을 설명한다. 실제 type과 경로는 TypeScript 전환 작업에서
+확정한다.
+
+```tsx
+import { MenuIcon } from "@/presentation/design-system/icons";
+import { IconButton } from "@/presentation/design-system";
+
+<IconButton accessibleName="메뉴 열기" onPress={openNavigation}>
+  <MenuIcon />
+</IconButton>
+```
+
+vendor 파일은 의미 이름과 공급자 이름을 분리한다.
+
+```tsx
+import {
+  Menu as LucideMenu,
+  X as LucideClose,
+  AlertTriangle as LucideWarning,
+} from "lucide-react";
+
+export const MenuGlyph = LucideMenu;
+export const CloseGlyph = LucideClose;
+export const WarningGlyph = LucideWarning;
+```
+
+`MenuGlyph` 같은 vendor export는 `semantic-icons.tsx` 밖으로 다시 노출하지
+않는다. 제품 코드는 `MenuIcon`, `CloseIcon`, `WarningIcon`만 사용한다.
+
+### 6.3 아이콘 추가 완료 조건
+
+- 기존 semantic icon으로 표현할 수 없는지 먼저 확인했다.
+- 서로 다른 제품 기능이 같은 의미 아이콘을 공유한다.
+- accessible name과 decorative 여부를 결정했다.
+- light/dark/high-contrast에서 보인다.
+- 200% zoom과 compact viewport에서 잘리지 않는다.
+- 신규 import 후 bundle budget을 통과한다.
+- 공급자 교체 시 제품 코드 수정이 필요하지 않다.
+
+## 7. Headless UI 선택 기준
+
+복잡한 overlay, collection, focus management를 직접 구현하기 전에 native
+platform과 검증된 headless UI를 평가한다.
+
+- [React Aria 공식 시작 문서](https://react-aria.adobe.com/getting-started)
+- [Radix Primitives 공식 소개](https://www.radix-ui.com/primitives/docs/overview/introduction)
+
+### 7.1 선택 순서
+
+1. native HTML만으로 요구 semantics와 모든 지원 브라우저 동작을 충족하는지
+   확인한다.
+2. native 구현이 불충분하면 React Aria와 Radix를 평가한다.
+3. 한 프로젝트에서 같은 문제를 해결하는 headless 공급자를 둘 이상 기본값으로
+   사용하지 않는다.
+4. 선택 결과와 버전·라이선스·bundle 영향을 ADR에 기록한다.
+5. 공급자 component를 local primitive로 감싼 뒤에만 제품 코드에 노출한다.
+
+### 7.2 평가표
+
+| 기준 | 확인 질문 |
+| --- | --- |
+| Semantics | WAI-ARIA pattern과 native semantics를 올바르게 사용하는가 |
+| Keyboard | roving focus, typeahead, Escape, arrow key가 완전한가 |
+| Focus | trap, restore, initial focus, nested overlay가 안전한가 |
+| Input modality | mouse, touch, keyboard, screen reader가 동일하게 동작하는가 |
+| i18n | RTL, locale number/date, IME를 지원하는가 |
+| Styling | semantic token과 Tailwind/CSS layer에 결합 가능한가 |
+| Bundle | component 단위 import와 tree shaking이 가능한가 |
+| React/Vite | 현재 React와 Vite 조합을 공식 지원하는가 |
+| SSR | future SSR profile에서 hydration ID가 안정적인가 |
+| Testing | 접근성·상호작용 테스트 자료와 utility가 있는가 |
+| Maintenance | release cadence, security 대응, license가 허용 가능한가 |
+
+현재 스켈레톤의 접근성·국제화 목표에는 React Aria Components가 우선 후보다.
+Radix는 overlay와 primitive composition을 중심으로 평가할 수 있다. 최종 선택은
+실제 prototype으로 `Select`, `Menu`, `Drawer` 세 가지를 구현해 다음을 비교한 뒤
+확정한다.
+
+- keyboard matrix
+- screen reader announcement
+- RTL
+- mobile touch
+- dark/high-contrast
+- gzip 증가량
+- local API로 감쌀 때 필요한 코드량
+
+공급자를 선택하더라도 `SelectProps = AriaSelectProps`처럼 vendor type alias를
+그대로 공용 API로 만들지 않는다. 제품이 실제로 지원하는 의미만 local prop으로
+닫는다.
+
+## 8. 접근성 계약
+
+목표는 WCAG 2.2 AA에 맞춘 기본 동작이다. 자동 도구 통과는 적합성 선언이 아니며,
+키보드와 보조기술 검토를 함께 수행한다.
+
+### 8.1 모든 컴포넌트의 공통 기준
+
+- 올바른 native element와 role을 사용한다.
+- visible label 또는 accessible name이 있다.
+- keyboard만으로 모든 action을 실행할 수 있다.
+- focus 순서가 DOM과 시각 순서에 맞는다.
+- focus indicator를 제거하지 않는다.
+- disabled와 readonly를 구분한다.
+- 상태는 색상만으로 전달하지 않는다.
+- 오류는 해당 control과 programmatically 연결한다.
+- 필요한 변경만 live region으로 한 번 알린다.
+- `prefers-reduced-motion`에서 불필요한 motion을 제거한다.
+- 200% text zoom과 400% page zoom에서 정보가 손실되지 않는다.
+- 320 CSS px reflow에서 양방향 scroll을 강요하지 않는다.
+- touch target은 기본 44x44 CSS px를 목표로 한다.
+- forced-colors에서 border, focus, selected state가 사라지지 않는다.
+- RTL에서 logical direction과 key behavior를 검증한다.
+- 한글·일본어·중국어 IME composition 중 입력을 조기에 검증하거나 제출하지
+  않는다.
+
+### 8.2 Overlay 기준
+
+- 열기 trigger를 기록한다.
+- 열릴 때 의미 있는 initial focus를 둔다.
+- modal일 때 focus가 내부를 벗어나지 않는다.
+- 배경 content를 `inert` 또는 동등한 방식으로 비활성화한다.
+- Escape와 명시적 닫기 action을 제공한다.
+- 닫은 뒤 trigger 또는 안전한 대체 위치로 focus를 복원한다.
+- nested overlay와 route transition 중 orphan portal을 남기지 않는다.
+
+### 8.3 Form 기준
+
+- label, description, error가 동일한 field ID 체계로 연결된다.
+- required는 시각적 기호와 programmatic 상태를 함께 가진다.
+- submit 실패 시 error summary로 focus를 이동한다.
+- error summary 항목은 해당 field로 이동한다.
+- async validation은 현재 입력보다 오래된 결과를 폐기한다.
+- pending 상태를 screen reader에 알리되 같은 문구를 반복하지 않는다.
+- 서버 오류의 raw body, stack, 내부 field path를 출력하지 않는다.
+
+## 9. 국제화 계약
+
+RP-08에서 디자인 시스템 primitive의 닫기, alert, toast, 글자 수 같은 기본
+문구는 `useLocale()` typed catalog로 이동했다. 제품 의미를 가진 label은 여전히
+명시적인 prop으로 받으며 primitive가 feature message key를 소유하지 않는다.
+
+필수 국제화 기반:
+
+- `LocaleProvider`
+- typed message key
+- fallback locale
+- `<html lang>`과 `dir` 갱신
+- `Intl.DateTimeFormat`
+- `Intl.NumberFormat`
+- `Intl.ListFormat`
+- plural/select message
+- locale별 validation message
+- pseudo-locale
+- RTL story와 E2E smoke
+
+현재 구현 위치와 실패 정책:
+
+- `presentation/i18n/catalog.ts`: 137개 canonical common key와 locale parity
+- `message-contract.ts`: key별 interpolation, fallback과 compatibility alias
+- `formatters.ts`: UTC-default date, number, relative time, list, plural/select
+- `locale-provider.tsx`: document `lang/dir`과 React consumer API
+- missing key/parameter와 formatter 예외: 빈 문자열이나 raw key 대신 안전한
+  fallback
+- `en-XA`: 긴 문자열/320px reflow, `ar-EG`: logical layout/RTL keyboard smoke
+- backend raw message와 translated HTML: 정적 negative gate에서 거절
+
+금지 패턴:
+
+- 번역 문장 중간에 JSX 문자열을 연결한다.
+- 날짜를 `substring`이나 고정 구분자로 조립한다.
+- icon direction을 locale 확인 없이 좌/우 이름으로 고정한다.
+- route title, navigation label, toast message를 JSX literal로 분산한다.
+- 번역 누락 시 빈 문자열을 렌더링한다.
+
+RP-10의 Storybook toolbar에서 최소한 다음 조합을 전환할 수 있어야 한다.
+
+- `ko-KR`, light
+- `en-US`, light
+- `en-US`, dark
+- pseudo-locale
+- 대표 RTL locale
+
+## 10. Storybook과 시각 검증
+
+현재 `/examples/ui`는 실행 중인 앱 셸과 primitive 통합을 확인하는 데 유지한다.
+그러나 runtime gallery는 isolated component workshop을 대체하지 않는다.
+
+[Storybook 공식 UI 테스트 문서](https://storybook.js.org/docs/writing-tests)는
+story를 기반으로 interaction, accessibility, visual test를 구성하는 방법을
+제공한다.
+
+### 10.1 Storybook 필수 구성
+
+- Vite 기반 Storybook
+- TypeScript CSF story
+- global theme toolbar
+- locale/RTL toolbar
+- compact/wide viewport
+- Router, Theme, Locale, Session, Query decorator
+- `@storybook/addon-a11y`
+- a11y 결과를 CI에서 error로 처리
+- interaction `play` test
+- story build gate
+
+### 10.2 각 컴포넌트의 필수 story
+
+- default
+- 모든 semantic variant
+- disabled와 readonly
+- pending/loading
+- 오류
+- 긴 문구
+- 빈 값
+- light/dark
+- compact viewport
+- keyboard interaction
+- 해당되는 경우 open/closed, controlled/uncontrolled
+
+Form과 overlay는 다음 story를 추가한다.
+
+- submit 실패와 error summary
+- async pending
+- server field error
+- Escape close
+- outside interaction
+- initial focus
+- focus restoration
+- nested content와 long content
+
+### 10.3 시각 회귀
+
+기본 시각 회귀는 Playwright `toHaveScreenshot()`을 사용해 저장소 안에서 실행할
+수 있게 한다. Chromatic 같은 외부 서비스는 선택 사항이다.
+
+필수 안정화:
+
+- 동일한 Linux image, browser version, font
+- animation과 caret 비활성화
+- 시간·랜덤·network 응답 고정
+- 동적 ID와 민감 데이터 mask
+- light/dark baseline
+- compact/wide baseline
+- 변경된 baseline은 코드 리뷰 대상
+
+failure screenshot은 시각 회귀가 아니다. 의도된 baseline과 실제 렌더링을
+비교하는 assertion이 있어야 한다.
+
+### 10.4 테스트 계층
+
+| 계층 | 검증 대상 |
+| --- | --- |
+| Type check | prop union, ref, event와 slot type |
+| Unit | token/variant map, pure formatter와 state reducer |
+| Component | native semantics, keyboard, focus, callback |
+| Story interaction | 실제 browser의 isolated behavior |
+| Story a11y | 모든 주요 state의 axe |
+| Visual | pixel/layout/theme regression |
+| E2E | 앱 셸, route, form/query integration |
+| Manual | screen reader, zoom, touch, forced-colors |
+
+DOM snapshot은 보이는 UI를 보장하지 않으므로 public markup contract가 꼭 필요한
+경우에만 사용한다.
+
+## 11. 컴포넌트 추가 Recipe
+
+새 component를 추가할 때 다음 순서를 생략하지 않는다.
+
+### Step 1. 문제와 계층을 결정한다
+
+다음 질문을 issue 또는 설계 메모에 기록한다.
+
+- 단일 control인가, 반복되는 조합인가, 페이지 구조인가?
+- primitive, pattern, template 중 어디에 속하는가?
+- 기존 component의 variant로 해결할 수 있는가?
+- 제품 전용 의미를 공통 디자인 시스템으로 잘못 올리는 것은 아닌가?
+- native HTML로 충분한가?
+
+### Step 2. 상태 행렬을 작성한다
+
+최소 상태:
+
+```text
+default
+hover
+focus-visible
+active/pressed
+disabled
+pending
+invalid
+light
+dark
+compact
+long-content
+```
+
+선택/overlay component는 open, selected, indeterminate, empty, loading도 포함한다.
+
+### Step 3. 접근성 명세를 작성한다
+
+- element/role
+- accessible name
+- keyboard table
+- focus entry/exit/restore
+- announcement
+- error association
+- reduced motion
+- touch와 screen reader
+
+명세가 불명확하면 구현보다 먼저 native, React Aria, Radix prototype으로 검증한다.
+
+### Step 4. API를 닫는다
+
+- TypeScript public props를 정의한다.
+- semantic `variant`를 사용하고 raw color prop을 노출하지 않는다.
+- callback 이름과 payload를 domain-neutral하게 정한다.
+- controlled/uncontrolled 정책을 정한다.
+- `className` escape hatch의 범위를 정한다.
+- vendor prop과 type을 public API에 노출하지 않는다.
+
+### Step 5. 필요한 토큰을 추가한다
+
+- 기존 semantic token으로 표현 가능한지 확인한다.
+- raw 값 반복을 추가하지 않는다.
+- light/dark/forced-colors 값을 함께 정의한다.
+- token contract test를 갱신한다.
+
+### Step 6. 구현한다
+
+- native semantics 우선
+- local vendor facade만 import
+- static variant map
+- ref/focus 지원
+- DOM 구조 최소화
+- render 중 전역 상태 변경 금지
+- 제품 API나 application service import 금지
+
+### Step 7. Story를 작성한다
+
+- 상태 행렬을 모두 story로 표현한다.
+- interaction test를 작성한다.
+- dark, compact, long-content를 포함한다.
+- a11y test를 error mode로 실행한다.
+
+### Step 8. 자동 테스트를 작성한다
+
+- role/name 중심 query
+- keyboard와 focus
+- disabled/pending
+- callback
+- controlled state
+- 오류와 live region
+- 필요한 visual baseline
+
+구현 class나 내부 DOM 순서만 확인하는 brittle test는 피한다.
+
+### Step 9. 통합 예제를 추가한다
+
+- `/examples/ui`에는 primitive를 추가한다.
+- `/examples/states`에는 새로운 공통 상태를 추가한다.
+- pattern/template은 domain-neutral fixture로 실제 조합을 보여 준다.
+- production profile에서 예제 route를 제외할 수 있는 계약을 유지한다.
+
+### Step 10. 문서와 public export를 갱신한다
+
+- 사용 목적
+- 사용하지 말아야 할 경우
+- props와 variant
+- keyboard
+- 접근성 책임
+- i18n
+- 예제
+- public `index.ts` export
+- 변경 로그
+
+### Step 11. 게이트를 실행한다
+
+최소 실행 범위:
+
+```bash
+corepack pnpm check:types
+corepack pnpm lint
+corepack pnpm check:architecture
+corepack pnpm test:component
+corepack pnpm test:e2e
+corepack pnpm test:a11y
+corepack pnpm build
+corepack pnpm check:bundle
+```
+
+Storybook과 visual gate가 도입된 뒤에는 story build, interaction, story a11y,
+visual comparison도 필수로 추가한다.
+
+## 12. Definition of Done
+
+컴포넌트는 아래 항목 중 자신의 state/capability matrix에 해당하는 항목을
+충족해야 `완료`다. 적용되지 않는 항목은 체크를 생략하지 말고 `N/A`와 이유를
+component contract에 기록한다. 예를 들어 `Separator`에는 pending/error/IME가,
+읽기 전용 `Card`에는 controlled state와 field error가 적용되지 않는다.

+## 14. 단계별 도입 순서
+
+1. TypeScript public API와 디자인 시스템 public barrel을 만든다.
+2. token을 primitive/semantic/component 계층으로 분리한다.
+3. 기존 Button, TextField, Card, Alert, Badge, Dialog를 새 계약으로 이동한다.
+4. Lucide local facade와 `IconButton`을 추가하고 문자 glyph를 제거한다.
+5. Field foundation과 필수 form primitives를 추가한다.
+6. React Aria와 Radix prototype을 비교하고 headless ADR을 확정한다.
+7. Drawer, Select, Menu, Popover, Tooltip을 local facade로 구현한다.
+8. pattern과 page template을 추가한다.
+9. locale provider, pseudo-locale, RTL 검증을 추가한다.
+10. Storybook, story a11y, interaction test를 추가한다.
+11. pinned browser 환경의 visual regression gate를 추가한다.
+12. `/examples/ui`와 `/examples/states`를 통합 smoke gallery로 유지한다.
+
+이 순서는 라이브러리 수를 늘리는 것이 목표가 아니다. 각 단계가 제품 개발자가
+중복 구현할 문제를 하나씩 제거하고, 외부 공급자를 교체할 수 있는 로컬 계약과
+검증 증거를 남기는 것이 목표다.

+# Design-token styling contract
+
+`src/presentation/styles/theme.css` is the styling SSOT. Components consume
+semantic color, spacing, typography, status, and radius tokens through static
+classes. `/examples/ui` is the executable token and primitive gallery.
+
+## Theme contract
+
+The supported public preference is the closed set `system`, `light`, and
+`dark`. `ThemeProvider` reads and writes `COLOR_SCHEME` through the application
+storage port; it does not access a raw storage key. `system` subscribes to
+`prefers-color-scheme` changes. Bootstrap applies the persisted preference
+before React paints.
+
+Components use semantic tokens such as `--color-panel`, `--color-content`,
+`--color-border`, `--color-action`, and status surface/content/border triples.
+They must not hard-code a light-only panel or text color. Both light and dark
+surfaces are included in automated axe checks.
+
+## Included primitives
+
+- `Button`: primary, secondary, danger, and ghost intent
+- `TextField`: label, help text, required state, and associated validation error
+- `Card`: labelled surface with optional footer
+- `Alert` and `Badge`: non-color-only status feedback
+- `Dialog`: native modal semantics, Escape/backdrop close, and trigger focus
+  restoration
+- async and access state surfaces: loading, refresh, empty, terminal error,
+  auth required, forbidden, and not found
+
+Arbitrary-value policy:
+
+- prefer a named semantic token
+- bracket values are allowed only for one-off platform constraints that cannot
+  be expressed by the current scale
+- a repeated bracket value must be promoted into `@theme`
+- user-controlled or runtime-composed class strings are forbidden
+- class variants must be selected from a closed static map
+
+The removable reference feature may demonstrate tokens, but generic production
+starter modules do not import its domain, application, adapter, or presentation
+implementation.
+
+This file documents the currently implemented token and primitive baseline.
+The [design-system platform contract](./design-system-platform.md) defines the
+target token layers, component catalog, local Lucide/headless-library
+facades, page patterns, accessibility and internationalization rules, isolated
+workshop, and component-authoring recipe. Items in that target document are not
+treated as implemented until their acceptance tests pass.
