+# FSD Frontend Refactor
+
+## Цель
+
+Довести фронтенд-архитектуру до эталонного Feature-Sliced Design (FSD) — устранить существующие нарушения, вынести жирные страницы в виджеты/фичи, внедрить автоматический контроль FSD-правил.
+
+Текущее состояние: 4.2/5 по FSD-зрелости. Цель: 5/5.
+
+## Задачи
+
+### 1. Исправить нарушение слоёв в shared/lib/test
+
+- `shared/lib/test/test-utils.tsx` импортирует `SessionProvider` из `@/app/providers`
+- Это единственное нарушение FSD (shared → app)
+- Решение: вынести `TestSessionProvider` в `shared/lib/test/` и переключить `test-utils.tsx` на него
+- Тесты не должны сломаться: `TestSessionProvider` предоставляет те же значения контекста (замоканые)
+
+### 2. Вынести BrokerPositionTable из страницы в виджет
+
+- `pages/broker-positions/ui/BrokerPositionsPage.tsx` (310 строк) содержит внутренние компоненты:
+  - `BrokerPositionTable` (~190 строк) — таблица с пагинацией, skeleton, inline-стилями
+  - `PositionTicker` (~20 строк) — ссылка на инструмент
+  - `formatQuantity` — хелпер
+- Решение: создать `widgets/broker-positions-table/` с:
+  - `ui/BrokerPositionTable.tsx`
+  - `ui/PositionTicker.tsx`
+  - `index.ts`
+- Страница сокращается до ~100 строк (только cursor-логика + композиция)
+
+### 3. Вынести BrokerSummary, BrokerAssetCards, BrokerOverviewSkeleton в виджет
+
+- `pages/broker-account/ui/BrokerAccountOverviewPage.tsx` (160 строк) содержит:
+  - `BrokerSummary` — сводка портфеля (карточки стоимости и денег)
+  - `BrokerAssetCards` — карточки классов активов (акции/облигации)
+  - `BrokerOverviewSkeleton` — скелетон загрузки
+  - `allocationPercent`, `formatAllocationPercent` — хелперы
+- Решение: создать `widgets/broker-overview/` с:
+  - `ui/BrokerSummary.tsx`
+  - `ui/BrokerAssetCards.tsx`
+  - `ui/BrokerOverviewSkeleton.tsx`
+  - `index.ts`
+- Страница сокращается до ~40 строк (только loading/error guard + композиция)
+
+### 4. Вынести AddPositionForm в фичу
+
+- `pages/portfolios/ui/PortfolioDetailPage.tsx` (290 строк) содержит inline-форму добавления позиции:
+  - 4 state-переменные (newSecid, newQty, newPrice, newDate)
+  - 4 input-поля с inline-стилями
+  - Валидация и submit
+- Это полноценная бизнес-фича, не место в странице
+- Решение: создать `features/add-position/` с:
+  - `api/useAddPosition.ts` — мутация (обёртка над usePositionMutations)
+  - `model/useAddPositionForm.ts` — управление формой
+  - `ui/AddPositionForm.tsx` — UI формы
+  - `index.ts`
+- Страница сокращается до ~140 строк (showAddForm toggle + `<AddPositionForm portfolioId={id} />`)
+
+### 5. Вынести cursor-пагинацию в shared-хук
+
+- 25 строк cursor-логики дублируются в:
+  - `pages/broker-positions/ui/BrokerPositionsPage.tsx`
+  - `pages/broker-operations/ui/BrokerOperationsPage.tsx`
+- Решение: создать `shared/lib/useCursorPagination.ts`
+
+```ts
+function useCursorPagination() {
+  // cursor, pageNumber, handleNext(cursor), handlePrevious, reset
+}
+```
+
+### 6. Добавить ESLint-плагин FSD
+
+- Текущий `import/no-restricted-paths` проверяет только межслойные границы
+- Плагин `@conarti/eslint-plugin-feature-sliced` добавит:
+  - Проверки public API (запрет импорта из внутренних модулей в обход index.ts)
+  - Проверки сегментов (api/ui/model не импортируют друг друга напрямую)
+- Решение: установить плагин и включить recommended rules
+
+## Критерии приёмки (Acceptance Criteria)
+
+- [ ] AC1: `test-utils.tsx` не импортирует из `@/app/*`
+- [ ] AC2: `widgets/broker-positions-table` создан, страница использует его
+- [ ] AC3: `widgets/broker-overview` создан, страница использует его
+- [ ] AC4: `features/add-position` создана, страница использует её
+- [ ] AC5: `shared/lib/useCursorPagination.ts` создан, обе страницы используют его
+- [ ] AC6: `@conarti/eslint-plugin-feature-sliced` установлен и настроен
+- [ ] AC7: `npm run lint` проходит без ошибок
+- [ ] AC8: `npm run build` проходит без ошибок
+- [ ] AC9: Все существующие тесты проходят (включая тесты рефакторимых компонентов)
+- [ ] AC10: Визуально поведение страниц не изменилось
+
+## Ограничения
+
+- Не менять API-контракты компонентов (пропсы, типы). Только перемещение кода.
+- Не добавлять новую функциональность — только рефакторинг.
+- inline-стили переносятся вместе с компонентами; централизация UI-кита — отдельная задача.

+# FSD Frontend Refactor — Tasks
+
+**Ветка:** `codex/fsd-frontend-refactor`

+- [ ] **Task 3:** Вынести BrokerSummary, BrokerAssetCards, BrokerOverviewSkeleton в widgets
+- [ ] **Task 4:** Вынести AddPositionForm в features/add-position
+- [ ] **Task 5:** Вынести useCursorPagination в shared/lib/
+- [ ] **Task 6:** Добавить @conarti/eslint-plugin-feature-sliced
+- [ ] **Финальная проверка:** `npm run build -w apps/frontend && npm run lint -w apps/frontend && npm run -w apps/frontend test run`
