fix(stock): 매매알람 detail 객체 렌더 크래시(React #31 ) 방지

/api/stock/trade-alerts의 alerts[].detail은 condition별 가변 객체 ({ma50,ma200,severity} 등)인데 JSX 자식으로 직접 렌더 → React #31로 페이지 크래시(워커가 실제 알람 발화 시작하며 발현, BE msg #17). formatDetail 헬퍼 추가: 객체를 안전 문자열로 변환(알려진 키 한글 라벨, *_pct 퍼센트, null 값 스킵, 미정의 키도 원문 폴백 — 스키마 가정 없음). AlertCard가 detail 대신 formatDetail(detail) 렌더. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UHXzpsZQxKG9hQmNRfZjRS

+# 관심종목 탭 (Watchlist Tab) Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** `/stock/trade` 거래 데스크에 관심종목 CRUD + 최근 매매 시그널 알림 이력을 보여주는 "관심종목" 탭을 추가한다.
+
+**Architecture:** 순수 헬퍼(`watchlistUtils.js`) → API 헬퍼(`api.js`) → 상태 훅(`useWatchlist.js`) → 표현 컴포넌트(`WatchlistTab.jsx`) → 탭 등재(`StockTrade.jsx`). 기존 `HoldingsIntelTab`/`usePortfolio` 패턴(훅을 `StockTrade`에서 인스턴스화해 탭에 props로 전달)을 그대로 따른다.
+
+**Tech Stack:** React 18 (함수형 + hooks), Vite, Vitest + @testing-library/react, 기존 `apiGet/apiPost/apiDelete` 헬퍼.
+
+## Global Constraints
+
+- **API는 항상 상대경로** (`/api/...`). 절대 URL 금지 (Mixed Content).
+- **모든 fetch는 `src/api.js`의 `apiGet/apiPost/apiDelete` 경유.**
+- 테스트: `import { describe, it, expect } from 'vitest'`. 실행 `npm run test:run`. 파일 컨벤션 `*.test.js(x)` 동일 디렉토리 배치.
+- 색상: 매수 `#22c55e`, 매도 `#ef4444` (기존 `ACTION_MAP` 팔레트 일치).
+- CSS 토큰 재사용: `--line`, `--surface`, `--radius-lg`, `--muted`, `--accent-stock`. 카드 관례: `background: rgba(255,255,255,0.03); border: 1px solid rgba(148,163,184,0.12); border-radius: 10px`.
+- 커밋은 `web-ui` 경로에서만. `.env`·무관 파일 커밋 금지 (변경 파일만 명시적 `git add`).
+- BE 계약 (소비 대상):
+  - `GET /api/stock/watchlist` → `{ watchlist: [{ ticker, name, note, params, added_at }] }`
+  - `POST /api/stock/watchlist` body `{ ticker, name?, note? }` → `{ ok: true }`
+  - `DELETE /api/stock/watchlist/{ticker}` → 200/404
+  - `GET /api/stock/trade-alerts?days=N` → `{ alerts: [{ id, ticker, name, kind, condition, price, detail, fired_at }] }`
+  - `kind`: `buy`|`sell`. `condition`: `buy_ma20_pullback`/`buy_breakout`/`buy_rsi_bounce`/`sell_stop_loss`/`sell_ma_break`/`sell_take_profit`/`sell_climax`/`sell_trailing_stop`.
+- 응답은 방어적 파싱: 배열 직접 반환 / 래핑(`watchlist`·`alerts`) 둘 다 허용.
+
+---
+
+### Task 1: 순수 헬퍼 `watchlistUtils.js` (라벨/색/시간 매핑)
+
+**Files:**
+- Create: `src/pages/stock/watchlistUtils.js`
+- Test: `src/pages/stock/watchlistUtils.test.js`
+
+**Interfaces:**
+- Produces:
+  - `KIND_META: { buy: {label,color,bg}, sell: {label,color,bg} }`
+  - `kindMeta(kind: string) => { label, color, bg }` (미정의 → 회색 폴백 + 원문 label)
+  - `CONDITION_LABEL: Record<string,string>`

+### Task 3: `WatchlistTab.jsx` 컴포넌트 + 스타일
+
+**Files:**
+- Create: `src/pages/stock/components/WatchlistTab.jsx`
+- Modify: `src/pages/stock/Stock.css` (파일 끝에 `wl-*` 섹션 추가)
+- Test: `src/pages/stock/components/WatchlistTab.test.jsx`
+
+**Interfaces:**
+- Consumes (Task 1): `kindMeta`, `conditionLabel`, `relativeTime`; (stockUtils) `formatNumber`; (Task 2) `useWatchlist` 반환 형태 — 단, 컴포넌트는 훅 결과를 `wl` **prop**으로 받는다(테스트/뱃지 용이).
+- Produces: `WatchlistTab({ wl })` 기본 export (React 컴포넌트).
+
+- [ ] **Step 1: Write the failing smoke test**
+
+Create `src/pages/stock/components/WatchlistTab.test.jsx`:
+
+```jsx
+import { describe, it, expect, vi } from 'vitest';
+import { render, screen } from '@testing-library/react';
+import WatchlistTab from './WatchlistTab.jsx';
+
+const baseWl = {
+  items: [], alerts: [], alertDays: 7, setAlertDays: vi.fn(),
+  loading: false, error: '', alertError: '', adding: false,
+  add: vi.fn(), remove: vi.fn(), reload: vi.fn(),
+};
+
+describe('WatchlistTab', () => {
+  it('빈 상태: 헤딩과 빈 안내 노출', () => {
+    render(<WatchlistTab wl={baseWl} />);
+    expect(screen.getByText('관심종목 관리')).toBeInTheDocument();
+    expect(screen.getByText(/아직 관심종목이 없습니다/)).toBeInTheDocument();
+    expect(screen.getByText(/발생한 알림이 없습니다/)).toBeInTheDocument();
+  });
+
+  it('종목·알림이 있으면 렌더', () => {
+    const wl = {
+      ...baseWl,
+      items: [{ ticker: '005930', name: '삼성전자', note: '반도체 대장', added_at: '2026-07-01T00:00:00Z' }],
+      alerts: [{ id: 1, ticker: '005930', name: '삼성전자', kind: 'buy', condition: 'buy_breakout', price: 81000, detail: '박스권 돌파', fired_at: '2026-07-03T01:00:00Z' }],
+    };
+    render(<WatchlistTab wl={wl} />);
+    expect(screen.getByText('삼성전자')).toBeInTheDocument();
+    expect(screen.getByText('매수')).toBeInTheDocument();
+    expect(screen.getByText('박스 상단 돌파')).toBeInTheDocument();
+  });
+});
+```
+
+> 참고: `toBeInTheDocument` 매처는 `@testing-library/jest-dom`(devDependency)에서 제공된다. 기존 테스트 셋업에서 전역 등록이 안 되어 있으면 테스트 파일 상단에 `import '@testing-library/jest-dom';` 한 줄을 추가한다.
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `npm run test:run -- src/pages/stock/components/WatchlistTab.test.jsx`

+- [ ] **Step 5: Run tests to verify they pass**
+

+
+### Task 4: `StockTrade`에 탭 등재 + 문서 갱신
+
+**Files:**
+- Modify: `src/pages/stock/stockUtils.js:152` (TAB 상수 추가)
+- Modify: `src/pages/stock/StockTrade.jsx` (import·훅·탭 배열·렌더)
+- Modify: `CLAUDE.md` (API 엔드포인트 테이블 — web-ui 루트가 아닌 `web-ui/CLAUDE.md`)
+
+**Interfaces:**
+- Consumes (Task 2·3): `useWatchlist`, `WatchlistTab`
+- Produces: 없음 (통합 지점, 최종 배선)
+
+- [ ] **Step 1: Add TAB constant**
+
+`src/pages/stock/stockUtils.js` 맨 끝(`export const TAB_HOLDINGS_INTEL = 'holdings_intel';` 뒤)에 추가:
+
+```js
+export const TAB_WATCHLIST = 'watchlist';
+```
+
+- [ ] **Step 2: Wire into StockTrade.jsx**
+
+`src/pages/stock/StockTrade.jsx` 수정 — 4곳:
+
+(a) stockUtils import에 `TAB_WATCHLIST` 추가 (기존 import 블록 line 6-10):
+
+```js
+import {
+    formatNumber, formatPercent,
+    toNumeric, profitColorClass,
+    TAB_PORTFOLIO, TAB_REPORT, TAB_ADVISOR, TAB_HOLDINGS_INTEL, TAB_WATCHLIST,
+} from './stockUtils';
+```
+
+(b) 탭 컴포넌트 import 추가 (기존 `import HoldingsIntelTab ...` 뒤, line 25 근처):
+
+```js
+import HoldingsIntelTab from './components/HoldingsIntelTab';
+import WatchlistTab from './components/WatchlistTab';
+```
+
+(c) 훅 인스턴스화 + `TAB_ORDER`/`tabLabels` 확장. `const [activeTab, ...]` 아래(line 31 근처)와 hooks 블록에 추가:
+
+```js
+    const wl = useWatchlist();
+
+    const TAB_ORDER = [TAB_PORTFOLIO, TAB_REPORT, TAB_ADVISOR, TAB_HOLDINGS_INTEL, TAB_WATCHLIST];
+    const tabLabels = ['포트폴리오', '리포트', '어드바이저', '보유종목 인텔', '관심종목'];
+```
+
+그리고 파일 상단 hooks import 목록에 훅 import 추가 (line 19 `import useAdvisor ...` 뒤):
+
+```js
+import useAdvisor from './hooks/useAdvisor';
+import useWatchlist from './hooks/useWatchlist';
+```
+
+`const wl = useWatchlist();` 는 다른 훅들(`const advisor = useAdvisor({...});`) 뒤에 배치.
+
+(d) 모바일 SwipeableView content 분기에 watchlist 추가. 기존 `: <HoldingsIntelTab />,` 를 다음으로 교체:
+
+```js
+                        content: tabId === TAB_PORTFOLIO
+                            ? <PortfolioTab pf={pf} asset={asset} handleSell={handleSell} handleSaveSnapshot={handleSaveSnapshot} />
+                            : tabId === TAB_REPORT
+                                ? <ReportTab pf={pf} report={report} ai={ai} marketCtx={marketCtx} />
+                                : tabId === TAB_ADVISOR
+                                    ? <AdvisorTab pf={pf} advisor={advisor} />
+                                    : tabId === TAB_HOLDINGS_INTEL
+                                        ? <HoldingsIntelTab />
+                                        : <WatchlistTab wl={wl} />,
+```
+
+(e) 데스크탑 탭 버튼 배열에 항목 추가. 기존 `{ id: TAB_HOLDINGS_INTEL, ... }` 항목 뒤에 추가:
+
+```js
+                            { id: TAB_HOLDINGS_INTEL, icon: '🔍', label: '보유종목 인텔', sub: '신호·이슈', className: 'stock-main-tab--holdings-intel' },
+                            { id: TAB_WATCHLIST, icon: '⭐', label: '관심종목', sub: '관리·시그널', badge: wl.items.length || null },
+```
+
+(f) 데스크탑 조건부 렌더 추가. 기존 `{activeTab === TAB_HOLDINGS_INTEL && <HoldingsIntelTab />}` 뒤에 추가:
+
+```js
+                    {activeTab === TAB_HOLDINGS_INTEL && <HoldingsIntelTab />}
+                    {activeTab === TAB_WATCHLIST && <WatchlistTab wl={wl} />}
+```
+
+- [ ] **Step 3: Run the full test suite**
+
+Run: `npm run test:run`
+Expected: PASS — 신규 3개 테스트 파일 포함 전체 통과 (기존 테스트 회귀 없음).
+
+- [ ] **Step 4: Lint + build**
+
+Run: `npm run lint`
+Expected: 신규 파일 관련 에러 0. (기존 코드의 사전 경고는 무시하되, 신규 파일이 새 에러를 만들지 않을 것.)
+
+Run: `npm run build`
+Expected: 빌드 성공 (`dist/` 생성, 에러 없음).
+
+- [ ] **Step 5: Manual verification (dev server)**
+
+```bash
+npm run dev
+```
+브라우저에서 `http://localhost:3007/stock/trade` 접속 → "관심종목" 탭이 데스크탑 탭바(⭐)와 모바일 스와이프에 노출되는지 확인. 종목코드 입력 후 추가 → 목록 반영, 삭제 버튼 동작, 기간 토글(1D/7D/30D) 확인. (BE 미배포 시 알림 패널은 에러/빈 상태로 표시되고 CRUD는 독립 동작해야 함.)
+
+- [ ] **Step 6: Update `web-ui/CLAUDE.md` API 테이블**
+
+`CLAUDE.md` (web-ui 프로젝트 루트) 의 "API 엔드포인트 목록" 테이블에 행 추가 (스크리너 관련 행 근처):
+
+```markdown
+| 관심종목 | GET | `/api/stock/watchlist` — { watchlist: [{ ticker, name, note, params, added_at }] } |
+| 관심종목 | POST | `/api/stock/watchlist` — body: { ticker, name?, note? } |
+| 관심종목 | DELETE | `/api/stock/watchlist/:ticker` |
+| 매매 시그널 | GET | `/api/stock/trade-alerts?days=N` — { alerts: [{ id, ticker, name, kind, condition, price, detail, fired_at }] } |
+```
+
+그리고 페이지 구조 표의 `/stock/trade` 행 설명에 "(포트폴리오·리포트·어드바이저·보유종목 인텔·관심종목 5탭)" 취지를 반영.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/pages/stock/stockUtils.js src/pages/stock/StockTrade.jsx CLAUDE.md
+git commit -m "feat(stock): 거래 데스크에 관심종목 탭 등재 + API 문서 갱신"

+# 관심종목 탭 (Watchlist Tab) — FE 설계
+
+- **작성일**: 2026-07-03
+- **역할/저장소**: FE (`web-ui`)
+- **상위 스펙(BE)**: `web-page-backend/docs/superpowers/specs/2026-07-02-realtime-trade-alerts-design.md` §2·§5.3
+- **상위 플랜(BE)**: `web-page-backend/docs/superpowers/plans/2026-07-02-realtime-trade-alerts.md`
+- **범위**: FE(web-ui)만. BE 계약(§5.3)을 소비하는 "관심종목" 탭 구현. 워커(web-ai)·BE는 별도 세션.
+
+---
+
+## 1. 배경 & 목표
+
+실시간 매매 알림 시스템의 매수 유니버스는 **"watchlist(사용자 관리) ∪ 당일 스크리너 후보"** 로 정의된다(BE 스펙 §2). 관심종목 관리 수단은 **"텔레그램 봇 명령 + web-ui 탭 둘 다"** 로 결정되었다. 본 문서는 그중 **web-ui 탭**을 정의한다.
+
+목표:
+1. 사용자가 관심종목을 웹에서 추가/조회/삭제(CRUD)할 수 있다.
+2. 최근 발생한 매수·매도 시그널 알림 이력을 웹에서 확인할 수 있다.
+
+비목표(YAGNI, v1 제외):
+- 종목별 조건 오버라이드(`params_json`: trailing_pct, stop_pct 등) 편집 — BE POST/PUT params 계약 미확정.
+- 실시간 WebSocket 알림 스트림 — 폴링/수동 새로고침으로 충분.
+- 텔레그램 설정 UI.
+
+---
+
+## 2. 소비할 BE 계약 (§5.3)
+
+| 메서드 | 경로 | 요청 | 응답 |
+|--------|------|------|------|
+| GET | `/api/stock/watchlist` | — | `{ watchlist: [{ ticker, name, note, params, added_at }] }` |
+| POST | `/api/stock/watchlist` | `{ ticker, name?, note? }` | 201 `{ ok: true }` |
+| DELETE | `/api/stock/watchlist/{ticker}` | — | 200 / 404 |
+| GET | `/api/stock/trade-alerts?days=N` | — | `{ alerts: [{ id, ticker, name, kind, condition, price, detail, fired_at }] }` |
+
+**알림 필드 enum (BE 스펙 §5.3):**
+
+- `kind`: `buy` | `sell`
+- `condition` (buy): `buy_ma20_pullback` · `buy_breakout` · `buy_rsi_bounce`
+- `condition` (sell): `sell_stop_loss` · `sell_ma_break` · `sell_take_profit` · `sell_climax` · `sell_trailing_stop`
+
+> 응답 래핑 키(`watchlist`/`alerts`)와 `params` 필드는 BE 스펙 문구 기준. FE는 방어적으로 파싱한다(배열 직접 반환 / 래핑 둘 다 허용, `params` 미사용이면 무시).
+
+---
+
+## 3. 배치 & 탭 등재
+
+`/stock/trade` (거래 데스크)에 5번째 메인 탭 **"관심종목"** 추가. 기존 탭 등재 패턴을 그대로 확장한다.
+
+- `src/pages/stock/stockUtils.js`: `export const TAB_WATCHLIST = 'watchlist';`
+- `src/pages/stock/StockTrade.jsx`:
+  - `TAB_ORDER` 배열에 `TAB_WATCHLIST` 추가
+  - `tabLabels` 에 `'관심종목'` 추가
+  - 데스크탑 탭 버튼 배열에 `{ id: TAB_WATCHLIST, icon: '⭐', label: '관심종목', sub: '관리·시그널', badge: <count> }` 추가
+  - 모바일 `SwipeableView` content 분기에 `WatchlistTab` 추가
+  - 데스크탑 조건부 렌더 `{activeTab === TAB_WATCHLIST && <WatchlistTab />}` 추가
+- 탭 뱃지 = 관심종목 개수(훅에서 노출).
+
+---
+
+## 4. 컴포넌트 구조 (접근안 A: 훅 + 자립형 탭)
+
+기존 `HoldingsIntelTab` 패턴(자립형 탭 컴포넌트 + api 헬퍼)에 상태 로직을 훅으로 분리한 형태.
+
+```
+src/pages/stock/
+├── hooks/
+│   └── useWatchlist.js         # CRUD + 알림 이력 상태·액션
+├── components/
+│   └── WatchlistTab.jsx        # 표현 (내부 소형 컴포넌트: WatchlistForm/Row, AlertCard)
+├── watchlistUtils.js           # 순수 헬퍼 (라벨/색/시간 매핑)
+└── watchlistUtils.test.js      # 헬퍼 유닛 테스트
+```
+
+### 4.1 `useWatchlist.js` (훅)
+
+상태:
+- `items: []` — 관심종목 목록
+- `alerts: []` — 알림 이력
+- `alertDays: 7` — 알림 기간 필터(1/7/30)
+- `loading`, `error`, `adding` (폼 제출 중)
+
+액션:
+- `load()` — `getWatchlist()` + `getTradeAlerts(alertDays)` 병렬 로드
+- `add({ ticker, name, note })` — 낙관적 추가 → 성공 시 `load()` 재조회, 실패 시 롤백 + 에러
+- `remove(ticker)` — 낙관적 제거 → 실패 시 롤백
+- `setAlertDays(days)` — 변경 시 알림만 재조회
+
+노출: `{ items, alerts, alertDays, setAlertDays, loading, error, adding, add, remove, load }`
+
+### 4.2 `WatchlistTab.jsx` (표현)
+
+- 마운트 시 `load()`.
+- **상단 패널 — 관심종목 관리**: 인라인 추가 폼(ticker 필수, name·note 선택) + 목록. 각 행: 종목명/코드/메모/등록일 + 삭제 버튼. 빈 상태 안내.
+- **하단 패널 — 최근 시그널**: 기간 토글(1D/7D/30D) + 알림 카드. 카드: `kind` 뱃지, `condition` 한글 라벨, `ticker`/`name`, `price`, `detail`, `fired_at` 상대시간.
+- 로딩/에러/빈 상태: `stock-panel` · `stock-error` · `stock-empty` 등 기존 클래스 재사용.
+- 하단 면책 문구(`hi-disclaimer` 유사): "※ 어드바이저리 알림이며 자동매매가 아닙니다."
+
+### 4.3 `watchlistUtils.js` (순수 헬퍼 — 테스트 대상)
+
+```js
+KIND_META = { buy: { label: '매수', color, bg }, sell: { label: '매도', color, bg } }
+CONDITION_LABEL = { buy_ma20_pullback: 'MA20 눌림 반등', buy_breakout: '박스 상단 돌파',
+  buy_rsi_bounce: 'RSI 과매도 반등', sell_stop_loss: '손절 라인', sell_ma_break: '이평선 이탈',
+  sell_take_profit: '목표가 도달', sell_climax: '과열 소진', sell_trailing_stop: '트레일링 스톱' }
+
+kindMeta(kind)         // 미정의 → 회색 폴백 + 원문 label
+conditionLabel(cond)   // 미정의 → 원문 그대로 반환
+normalizeTicker(str)   // trim만 수행(한국 종목코드=6자리 숫자, 대문자화 불필요)
+relativeTime(iso)      // '3분 전' / '2시간 전' / '어제' 등, 잘못된 값 → '' 폴백
+```
+
+---
+
+## 5. API 레이어 (`src/api.js` 추가)
+
+```js
+// ── Stock Watchlist / Trade Alerts ──
+export const getWatchlist   = ()        => apiGet('/api/stock/watchlist');
+export const addWatchlist   = (body)    => apiPost('/api/stock/watchlist', body);   // { ticker, name?, note? }
+export const removeWatchlist= (ticker)  => apiDelete(`/api/stock/watchlist/${encodeURIComponent(ticker)}`);
+export const getTradeAlerts = (days = 7)=> apiGet(`/api/stock/trade-alerts?days=${days}`);
+```
+
+전부 상대경로, 기존 `apiGet/apiPost/apiDelete` 재사용. `getWatchlist`/`getTradeAlerts` 응답은 훅에서 `data.watchlist ?? data ?? []`, `data.alerts ?? data ?? []` 로 방어적 파싱.
+
+---
+
+## 6. UX / 상호작용 세부
+
+- **추가 폼**: ticker 미입력 시 제출 비활성. 제출 중 `adding` → 버튼 로딩. 성공 시 폼 초기화.
+- **낙관적 갱신**: add/remove 즉시 UI 반영, 실패 시 이전 상태 롤백 + `stock-error` 메시지.
+- **중복 방지**: 이미 목록에 있는 ticker면 폼에서 안내(추가 차단).
+- **알림 카드 정렬**: `fired_at` 내림차순(최신 우선).
+- **빈 상태**: 관심종목 0개 / 알림 0개 각각 안내 문구.
+- **반응형**: 데스크탑 2열/모바일 1열은 기존 `stock-panel` 그리드 관례 따름.
+
+---
+
+## 7. 스타일
+
+`src/pages/stock/Stock.css` 하단에 `wl-*` 프리픽스 섹션 추가 (기존 `hi-*` 패턴과 동일 구성):
+- `.wl-form`, `.wl-list`, `.wl-row`, `.wl-row__meta`, `.wl-del`
+- `.wl-alerts`, `.wl-alert`, `.wl-kind-badge`, `.wl-cond`, `.wl-period-toggle`
+- 색상: 매수 초록 `#22c55e`, 매도 빨강 `#ef4444` (기존 `ACTION_MAP` 팔레트와 일치).
+
+---
+
+## 8. 테스트 (TDD)
+
+`watchlistUtils.test.js` — 순수 헬퍼 검증:
+1. `conditionLabel`: 정의된 8종 매핑 정확, 미정의 값은 원문 폴백.
+2. `kindMeta`: buy/sell 라벨·색, 미정의 kind 회색 폴백.
+3. `relativeTime`: 방금/분/시간/일 경계, 잘못된 입력 `''` 폴백.
+4. `normalizeTicker`: 공백 trim.
+
+컴포넌트/훅은 수동 검증(개발 서버 3007 + BE 계약) + 빌드/lint 통과로 확인. (기존 스크리너 훅 테스트처럼 필요 시 훅 테스트 추가 가능하나 v1 필수 아님.)
+
+---
+
+## 9. 완료 기준 (Acceptance)
+
+- [ ] 거래 데스크에 "관심종목" 탭 노출(데스크탑·모바일), 뱃지에 개수 표시.
+- [ ] 종목 추가/삭제가 BE 계약대로 동작(낙관적 갱신 + 실패 롤백).
+- [ ] 최근 알림 이력이 기간 토글별로 조회되고, kind/condition 한글 라벨·색으로 표시.
+- [ ] `watchlistUtils.test.js` 통과.
+- [ ] `npm run lint` · `npm run build` 통과.
+
+---
+
+## 10. 리스크 / 오픈 이슈
+
+- **응답 래핑 형태 미확정**: BE가 `{ watchlist: [...] }` 인지 배열 직접인지 문구 기준 불확실 → 방어적 파싱으로 흡수.
+- **알림 엔드포인트 미배포 가능성**: BE 세션 미완 시 GET `/api/stock/trade-alerts` 404/네트워크 오류 → 알림 패널은 에러 상태를 조용히 표시하고 관심종목 CRUD는 독립 동작하도록 분리.
+- **params 편집**: v1 제외. 추후 BE POST/PUT params 계약 확정 후 별도 스펙으로 확장.
