+# Issue #9 authenticated browser evidence
+
+This directory binds the dashboard menu-transition acceptance evidence to the exact working-tree files listed in `manifest.json`.
+
+## Captured transition
+
+- **Path:** `요약` → `분류 규칙`
+- **Input:** native Streamlit menu click in an authenticated HTTPS browser session
+- **Fixture:** generated synthetic SQLite database only
+- **Sampling:** 35 DOM/style frames at 50 ms intervals
+- **Viewport:** 1280 × 720
+- **Browser:** Headless Chrome 154 on Linux x86_64
+- **Fixture host:** Linux aarch64, Python 3.13.5, Streamlit 1.58.0, Uvicorn 0.49.0
+
+## Verified browser observations
+
+All eight manifest checks are true:
+
+- the HTML document marker stayed identical;
+- the sidebar marker stayed identical;
+- the page background stayed identical;
+- no post-click full-document `load` event occurred;
+- the target loading state was observed;
+- the previous `요약` body was absent in every loading frame;
+- the unrelated `fixture=preserved` query key survived;
+- final URL, selected menu, target body, and cleared loading state agreed.
+
+`browser-observations.json` contains every sampled frame, body hashes, URL state, history events, document/sidebar markers, computed background, runtime metadata, and explicit limitations. `final-state.jpg` is the final visible browser state; it contains no credential or secret.
+
+## Recheck
+
+Run the exact validator recorded in `manifest.json`. The captured result was:
+
+```text
+exit code: 0
+PASS source_hashes=5 artifact_hashes=2 checks=8/8 frames=35 full_document_loads=0
+```
+
+The browser action was executed through `mcp__playwright__browser_run_code_unsafe`. That API reports success/error rather than a numeric process exit code; this boundary is explicit in the manifest instead of being represented as a fabricated exit status.
+
+## Evidence boundaries
+
+- This is synthetic-fixture browser evidence, not operating-ledger evidence.
+- A fixture-only external wrapper delayed the rules renderer by two seconds so the loading interval could be sampled. It did not alter repository source.
+- A temporary HTTPS ingress adapter supplied trusted proxy scheme/Host metadata. Repository authentication and same-origin enforcement remained active.
+- The tunnel URL is intentionally ephemeral and is retained in the frame record only for provenance.
+- The screenshot supplements, but does not replace, the machine-readable continuous-frame observations.

+### dashboard-menu-transition
+
+- 책임: authenticated Dashboard에서 공통 shell/background를 유지하고 선택된 page body만 교체한다.
+- 종류·프로토콜: Streamlit rerun, `st.radio` callback, query parameter
+- 호출 대상·operation: `dashboard.app.main()` → `render_sidebar_nav()` → `render_dashboard_body()`
+- 버전: 1.0
+- 호출 주체: authenticated browser
+- 인증 방식: 기존 `gate` 계약 선행; 메뉴는 인증을 우회하지 않음
+- 필요 권한: valid Dashboard auth cookie
+
+#### 상태와 입력
+
+정확한 menu options/order는 `월정산`, `요약`, `자산/마감`, `거래내역`, `확인필요 큐`, `미분류`, `분류 규칙`, `카테고리`, `계좌`, `Import`이다. selected value는 `st.session_state["dashboard_page"]`에 둔다. 직접 query의 `page`가 known option이면 해당 page를, absent/unknown이면 `요약`을 사용한다.
+
+#### 출력·불변조건
+
+- callback은 `st.query_params["page"]`만 갱신하고 `month`, `account_id`, `filter` 등 sibling key를 보존한다.
+- menu click은 document/path navigation이 아니며 stable `st.empty` body container 안에서 target renderer를 실행한다.
+- 공통 sidebar, refresh control, CSS/background는 유지하고 body만 target content로 대체한다.
+- 느린 target에는 `<target> 불러오는 중…`을 표시한 뒤 renderer 완료 시 placeholder를 제거한다.
+- renderer 예외는 body 안의 `페이지를 불러오지 못했습니다. 다시 시도해 주세요.`와 retry control로 대체하며 예외 상세를 노출하지 않는다.
+- serialized callback이 여러 번 실행되면 마지막 selection이 query와 body의 최종 상태가 된다.

+| `renderer_unavailable` | rendering | target renderer exception | 가능 | generic error의 retry 클릭 | previous body 제거, auth/shell 유지 |
+
+#### 검증 경계
+
+AppTest는 callback, query mapping, synthetic renderer output과 error/loading event를 검증하지만 실제 browser의 document navigation 부재, paint timing, focus/scroll, network request 또는 perceived shell continuity를 증명하지 않는다. 따라서 `REQ-002.03-AC01`은 authenticated real-browser evidence가 필수이며 AppTest는 companion evidence일 뿐이다. history/back-forward와 path URL은 계약에서 제외한다.

+# REQ-002 — Dashboard 메뉴 전환 시 공통 화면 연속성
+
+## 1. 목적
+
+인증된 Dashboard에서 메뉴를 바꿀 때 문서 전체를 이동시키지 않고 공통 shell과 배경을 유지하며 body만 교체한다. 현재 메뉴 선택, URL 상태, 느린 렌더링, 렌더링 실패의 동작을 예측 가능하게 만든다.
+
+## 2. 배경
+
+Issue #9의 Dashboard 메뉴 전환 계약이다. REQ-001의 인증 경계, cookie, logout, page dispatch와 기존 금융 페이지 계약을 유지한 채 Streamlit 메뉴 전환을 연속적인 단일 화면으로 제공한다.
+
+## 3. 범위
+
+### 포함
+
+- Streamlit `st.radio` 기반 메뉴의 정확한 10개 label/order와 selected state
+- 메뉴 클릭 시 document navigation 없이 공통 shell/background를 유지하고 body만 교체
+- 느린 대상 page 렌더링 중 대상별 loading 표시
+- renderer 예외의 local generic error와 retry
+- 빠른 연속 선택에서 latest serialized selection wins
+- 직접 `?page=` 접근, 누락/unknown page의 `요약` fallback, sibling query key 보존
+- 기존 auth gate, cookie, logout, finance page, cache-clear 회귀 검증
+
+### 제외
+
+- browser history/back-forward 동작, history API 계약, path URL 설계
+- 인증 방식·cookie 속성·MCP transport·SQLite schema 변경
+- page renderer의 금융 계산·gateway 의미 변경
+- 별도 document route 또는 full-document navigation 구현
+
+## 4. 용어와 기준
+
+- **공통 shell**: 인증 후 `dashboard/app.py`가 제공하는 sidebar, 메뉴, refresh control 및 앱 배경/CSS.
+- **body**: 선택된 page renderer가 공통 shell 안에서 채우는 주 콘텐츠 영역.
+- **latest serialized selection**: Streamlit rerun/콜백 직렬화 순서에서 마지막으로 반영된 `dashboard_page` 선택.
+- **AppTest**: Streamlit `streamlit.testing.v1.AppTest`의 synthetic runtime 검증. DOM, 실제 browser document navigation, 실제 paint/지연 체감은 검증하지 못한다.
+- **real-browser evidence**: 실제 browser에서 authenticated session으로 메뉴를 클릭하고 URL/document/body/shell을 관찰해 남기는 증거. AppTest를 대체하지 않으며 AppTest만으로 충족할 수 없는 browser-level 항목에 필수다.
+
+## 5. 요구사항
+
+### REQ-002.01 — 메뉴 정체성
+
+메뉴는 정확히 다음 순서와 label을 유지한다: `월정산`, `요약`, `자산/마감`, `거래내역`, `확인필요 큐`, `미분류`, `분류 규칙`, `카테고리`, `계좌`, `Import`. selected state는 현재 page와 일치한다.
+
+### REQ-002.02 — URL과 직접 접근
+
+메뉴 선택은 query의 `page`만 대상 label로 갱신하고 `month`, `account_id`, `filter` 등 sibling query key를 보존한다. 직접 `?page=<known>`은 해당 page를 렌더링하고, missing/unknown 값은 `요약`으로 fallback한다.
+
+### REQ-002.03 — 연속 화면
+
+메뉴 클릭은 document navigation을 일으키지 않는다. 공통 shell과 background는 유지하고 body만 선택된 renderer의 내용으로 교체한다. history/back-forward와 path URL은 이 요구사항의 판정 범위가 아니다.
+
+### REQ-002.04 — 전환 중 표시
+
+느린 renderer가 실행되는 동안 target page label을 포함한 `불러오는 중…` loading을 대상 body 영역에 표시하고, renderer 완료 후 loading placeholder를 제거한다.
+
+### REQ-002.05 — local failure와 retry
+
+target renderer 예외는 공통 shell을 무너뜨리지 않고 body 영역을 generic error와 `다시 시도` control로 교체한다. 예외 상세·secret은 UI에 노출하지 않는다.
+
+### REQ-002.06 — 최신 선택 우선
+
+연속 메뉴 선택은 serialized callback 순서의 마지막 선택을 query와 body에 반영하며 이전 선택이 마지막 상태를 덮어쓰지 않는다.
+
+### REQ-002.07 — 인증 경계 보존
+
+모든 menu/page dispatch는 REQ-001 gate와 cookie 검증 뒤에만 실행된다. no-cookie/invalid-cookie는 page body에 도달하지 않으며 valid cookie는 기존 Dashboard에 접근한다.
+
+### REQ-002.08 — 금융 page 회귀 없음
+
+요약, 자산/마감, 분류 규칙, 확인필요 큐, 월정산의 기존 synthetic fixture DB 핵심 내용과 기존 page query 계약을 유지한다.
+
+### REQ-002.09 — 운영 control 회귀 없음
+
+refresh control은 기존 `clear_cache` callable 계약을 유지하고, 메뉴 전환은 cache-clear 동작을 변경하지 않는다.
+
+## 6. 제약과 불변조건
+
+- `dashboard/app.py`의 auth gate와 page dispatch는 유지하며 인증 전에 DB path를 resolve하지 않는다.
+- 메뉴 클릭은 full document reload 또는 path navigation을 추가하지 않는다.
+- body 교체는 stable `st.empty` container 안에서 수행하며 공통 shell/background를 삭제하지 않는다.
+- loading/error/retry는 target body에 국소적으로 표시하고 generic error 외 renderer exception 내용을 공개하지 않는다.
+- query update는 `page` key만 변경하며 sibling page-specific key를 삭제하거나 정규화하지 않는다.
+- REQ-001의 auth/cookie/logout, financial gateway/page, cache-clear, MCP 및 SQLite semantics는 변경하지 않는다.
+
+## 7. 인수 기준
+
+각 기준은 하나의 명시된 test/evidence target으로 판정한다. AppTest는 synthetic runtime 판정이며 real-browser evidence가 필요한 기준을 대신하지 않는다.
+
+### REQ-002.01-AC01 — label/order/selected

+
+## 8. 오류 및 충돌 계약
+
+인증 실패는 항상 REQ-001 gate가 우선하며 메뉴·query로 우회할 수 없다. renderer 실패는 해당 body만 generic error/retry로 대체한다. 빠른 선택은 Streamlit serialized callback 순서를 따르며 마지막 serialized selection이 최종 상태다. history/back-forward와 path URL은 요구하지 않는다.

+인증 gate와 기존 `dashboard-01` page dispatch의 선행 순서는 변하지 않는다. valid cookie를 통과한 뒤에만 menu transition flow가 실행되며, auth 실패는 기존 cleanup/unauthenticated 흐름으로 종료된다.
+
+### transition — authenticated body replacement
+
+- 시작 이벤트: authenticated browser selects a value in `st.radio(key="dashboard_page")`
+- 선행조건: `gate-02` success; current page/query resolved
+- 실행 방식: Streamlit callback and rerun, no document/path navigation
+- 트랜잭션·영속성 경계: no new persistence; existing financial SQLite rules unchanged

+| 단계 ID | 실행 주체 | 시작 조건·입력 | 처리 | 읽기·쓰기 상태 | 외부 호출 | 성공 시 다음 단계 | 실패 시 전이 |
+|---|---|---|---|---|---|---|---|
+| `transition-01` | dashboard app/common | authenticated selected menu | `render_sidebar_nav` reads exact 10 options and selected state | session state `dashboard_page` | Streamlit radio callback | `transition-02` | `dashboard-fail` |
+| `transition-02` | common callback | selected `dashboard_page` | write query `page` only; preserve sibling query keys | browser query state | Streamlit query params | `transition-03` | `transition-03` |
+| `transition-03` | dashboard app | validated page | open stable `st.empty` body, show target loading, invoke target renderer | body placeholder only; existing DB reads/writes | page/gateway code | `transition-04` | `transition-error` |
+| `transition-04` | dashboard app | renderer completed | remove target loading and leave target body; shell/background remain | body replacement only | none | `authenticated` | `dashboard-fail` |
+| `transition-error` | dashboard app | renderer exception | clear partial body and show generic error/retry locally | body error state only | none | retry reruns target | `authenticated` with shell intact |
+
+### transition invariants
+
+- known direct `?page=` selects that page; missing/unknown selects `요약`.
+- serialized rapid selections commit the latest selection only.
+- menu transition never runs before auth and never changes cookie/logout/DB schema/MCP semantics.
+- history/back-forward and path URL behavior are explicitly outside this flow.

+### transition verification boundary
+
+`tests/test_dashboard_menu_transition.py` provides exact AppTest/unit evidence for labels, query preservation, fallback/direct access, loading, local error, latest selection, and cache-clear. `tests/test_dashboard_app.py::test_streamlit_apptest_core_pages_use_synthetic_fixture_db` and `tests/test_dashboard_authentication_app.py::test_valid_cookie_allows_dashboard_and_is_not_stored_in_session_state` cover finance/auth regressions. AppTest is synthetic and cannot establish actual browser document continuity, paint timing, focus/scroll, or network behavior; `scripts/streamlit_browser_evidence.py --mode transition`의 authenticated HTTPS frame/DOM/document/shell evidence가 REQ-002.03-AC01에 필수다. `tests/test_streamlit_browser_evidence.py`는 이 manifest가 실제 teardown 이후에만 성공하고 document navigation, shell identity drift, 누락 관찰 또는 secret 포함 시 fail-closed하는지 검증한다.
