+
+**Goal:** Устранить дублирование в серверных роутах: asyncHandler декоратор, validateGalleryImages, findUserOrder.
+
+**Architecture:** Вынос повторяющихся паттернов в shared-хелперы (`server/src/lib/`), замена ручного try/catch на декоратор.
+

+# Admin Orders UX Improvements 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:** Добавить в списке заказов маркер `Цена не подтверждена` и заменить смену статуса в деталке на быстрые кнопки допустимых переходов.
+
+**Architecture:** Изменения ограничены фронтендом (`client`) и опираются на текущие поля заказа (`status`, `deliveryType`, `deliveryFeeLocked`) и текущую логику переходов `getAdminNextOrderStatuses`. Серверные API и контракты не меняются, синхронизация данных остается через существующую инвалидацию React Query.
+
+**Tech Stack:** React, TypeScript, MUI, TanStack React Query, Vitest, Testing Library.
+
+---
+
+## File Structure
+
+**Create:**
+- `client/src/shared/lib/order-requires-price-approval.ts`

+- Test: `client/src/shared/lib/__tests__/order-requires-price-approval.test.ts`
+
+- [ ] **Step 1: Write the failing unit test**

+# Refactoring Audit — Code Quality Improvements
+
+Date: 2026-05-27
+
+## Overview
+
+Системный рефакторинг кодовой базы shop (craftshop monorepo) по 5 направлениям: toast-уведомления, пустые catch-блоки, серверное дублирование, клиентское дублирование, обработка ошибок API.
+
+## Подпроект 1: Система toast-уведомлений
+
+### Проблема
+- Единственный `CartSnackbar` (Effector) только для "товар добавлен в корзину"
+- Остальные операции без обратной связи — только inline `<Alert>` на страницах
+- Нет централизованного показа ошибок от API
+
+### Решение
+
+**1.1 Effector-стор уведомлений** (`client/src/shared/model/notification.ts`)
+```ts
+type NotificationType = 'success' | 'error' | 'info' | 'warning'
+
+interface Notification {
+  id: string
+  type: NotificationType
+  message: string
+  autoHideDuration?: number
+}
+
+// События
+addNotification      — добавить (генерирует id + пушит в очередь)
+dismissNotification  — закрыть по id
+dismissAll           — закрыть все
+
+// Стор
+$notifications: Notification[] — очередь, макс 3 видимых
+```
+
+**1.2 Компонент `NotificationStack`** (`client/src/shared/ui/NotificationStack/`)
+- Использует MUI `Snackbar` + `Alert` (уже стилизованы через тему)
+- Позиция: `bottom: 80px`
+- `Slide` transition, auto-hide по таймеру
+- Крестик для ручного закрытия
+- Не более 3 одновременных уведомлений (остальные в очереди)
+
+**1.3 Миграция CartSnackbar**
+- `cartAdded` событие пишет в `addNotification({ type: 'info', message: 'Товар добавлен в корзину' })`
+- Старый `CartSnackbar` удаляется (компонент, стор, тесты)
+- `ToggleCartIcon` и `AddToCartButton` — убрать прямой вызов `cartAdded`, заменить на `addNotification`
+
+**1.4 Интеграция с `useMutationWithToast`** (опционально, см. подпроект 5)
+
+### Файлы
+- Новые: `shared/model/notification.ts`, `shared/ui/NotificationStack/NotificationStack.tsx`, `shared/ui/NotificationStack/index.ts`
+- Изменённые: `app/App.tsx` (+ NotificationStack), удаление `features/cart/model/cart-notifications.ts`, `features/cart/ui/CartSnackbar/`
+- Тесты: `shared/model/notification.test.ts`, `shared/ui/NotificationStack/NotificationStack.test.tsx`
+
+---
+
+## Подпроект 2: Пустые catch-блоки
+
+### Проблема
+17 мест с `catch { /* ignore */ }` или пустым телом.
+
+### Решение
+Минимальное логирование с контекстом:
+
+| Файл | Уровень | Сообщение |
+|------|---------|-----------|
+| `persist-token.ts` (3 места) | `console.warn` | `'[persist-token] Failed to ...'` |
+| `theme-controller.tsx` (2 места) | `console.warn` | `'[theme] Failed to ...'` |
+| `CookieConsentBanner.tsx` (2 места) | `console.warn` | `'[cookie-consent] Failed to ...'` |
+| `SseProvider.tsx` | `console.warn` | `'[sse] Connection error:'` |
+| `admin-gallery` (сервер) | `request.log.error` | Контекст операции |
+| Остальные серверные | `request.log.error` | Контекст операции |
+
+### Файлы
+Только изменения в существующих файлах. Новых файлов нет.
+
+---
+
+## Подпроект 3: Сервер — дублирование в роутах
+
+### Проблема
+- ~25 мест с ручным try/catch-паттерном
+- Дублирование валидации галерейных изображений (POST/PATCH admin/products)
+- Дублирование `prisma.order.findFirst({ where: { id, userId } })` в 3 файлах
+
+### Решение
+
+**3.1 `asyncHandler`** (`server/src/lib/async-handler.js`)
+```js
+function asyncHandler(fn) {
+  return async (request, reply) => {
+    try {
+      return await fn(request, reply)
+    } catch (err) {
+      request.log.error(err)
+      const statusCode = err.statusCode || 500
+      const message = err.statusCode ? err.message : 'Internal server error'
+      return reply.code(statusCode).send({ error: message })
+    }
+  }
+}
+```
+
+**3.2 `validateGalleryImages`** (`server/src/lib/validate-gallery-images.js`)
+- Проверка существования `galleryImages` в БД
+- Проверка наличия resized-версий
+- Используется в POST и PATCH admin/products
+
+**3.3 `findUserOrder`** (`server/src/lib/find-user-order.js`)
+- `prisma.order.findFirst({ where: { id, userId }, ... })` с included relations
+
+### Файлы
+- Новые: `server/src/lib/async-handler.js`, `server/src/lib/validate-gallery-images.js`, `server/src/lib/find-user-order.js`
+- Изменённые: ~10 server route files
+
+---
+
+## Подпроект 4: Клиент — дублирование
+
+### Проблема
+- 4 копии `useQuery({ queryKey: ['me', 'cart'], ... })`
+- Дублирование `orderStatusLabelRu` и `ORDER_STATUS_DATA`
+
+### Решение
+
+**4.1 `useCartQuery`** (`client/src/entities/cart/lib/use-cart-query.ts`)
+```ts
+export function useCartQuery() {
+  const user = useAuthUser()
+  return useQuery({
+    queryKey: ['me', 'cart'],
+    queryFn: fetchMyCart,
+    enabled: Boolean(user),
+  })
+}
+```
+Замена в 4 компонентах.
+
+**4.2 Дубль статусов**
+- `ORDER_STATUS_DATA` — единственный источник
+- `orderStatusLabelRu` удалить, импорты переписать на `ORDER_STATUS_DATA`
+
+### Файлы
+- Новые: `entities/cart/lib/use-cart-query.ts`
+- Изменённые: `AppHeader.tsx`, `CartPage.tsx`, `CheckoutPage.tsx`, `ToggleCartIcon.tsx`, удаление `order-status-labels.ts`
+
+---
+
+## Подпроект 5: Обработка ошибок API (клиент)
+
+### Проблема
+- Нет централизованного показа ошибок API
+- `CheckoutPage` показывает сырое `(error as Error).message`
+
+### Решение
+
+**5.1 `useMutationWithToast`** (`client/src/shared/lib/use-mutation-with-toast.ts`)
+```ts
+function useMutationWithToast(options) {
+  return useMutation({
+    ...options,
+    onSuccess: (data, ...rest) => {
+      if (options.successMessage) addNotification({ type: 'success', message: options.successMessage })
+      options.onSuccess?.(data, ...rest)
+    },
+    onError: (error, ...rest) => {
+      addNotification({ type: 'error', message: getApiErrorMessage(error) })
+      options.onError?.(error, ...rest)
+    },
+  })
+}
+```
+
+**5.2 `getApiErrorMessage`** улучшение (`client/src/shared/lib`)
+- Если сервер вернул `{ error: string }` — показать его
+- Ошибка сети → "Нет соединения с сервером."
+- 500 → "Произошла ошибка. Попробуйте позже."
+- Остальное → стандартное сообщение
+
+### Файлы
+- Новые: `shared/lib/use-mutation-with-toast.ts`
+- Изменённые: `shared/lib/get-api-error-message.ts`, `CheckoutPage.tsx` (исправить отображение ошибки)
+
+---
+
+## Порядок реализации
+
+Подпроекты независимы и могут выполняться в любом порядке. Рекомендуемый порядок:
+
+1. **Подпроект 2** (пустые catch) — быстрые и безопасные изменения, хороший разогрев
+2. **Подпроект 1** (toast) — база для подпроекта 5, новая функциональность
+3. **Подпроект 5** (useMutationWithToast) — строится поверх подпроекта 1
+4. **Подпроект 3** (сервер) — standalone
+5. **Подпроект 4** (клиент) — standalone
+
+## Тестирование
+
+- Каждый подпроект: `npm run lint` (или `npm run lint:fix`) + `npm test` для своей директории
+- Финальная проверка: `cd client && npm run build` (проверка типов)

+# Дизайн: Доработки админки заказов (маркер цены + быстрые статусы)
+
+**Дата:** 2026-05-28  
+**Статус:** Draft
+
+## Контекст
+
+Нужно улучшить UX в админке заказов по двум направлениям:
+
+1. Явно показывать в списке заказов, что требуется подтверждение цены (итоговой стоимости для оплаты).
+2. Сделать смену статуса заказа более удобной для администратора.
+
+Ограничения, согласованные в обсуждении:
+
+- Не вводим новый статус заказа для подтверждения цены.
+- Используем короткий текст для индикатора.
+- Для смены статуса выбираем формат быстрых кнопок доступных переходов (вместо выпадающего списка).
+
+## Цели
+
+- Сократить время на обнаружение заказов, требующих подтверждения цены.
+- Упростить и ускорить смену статуса до 1 клика.
+- Сохранить существующие API-контракты и логику допустимых переходов.
+
+## Не в рамках этой итерации
+
+- Изменение серверной статусной модели.
+- Добавление новых серверных полей или эндпоинтов.
+- Массовая смена статусов из таблицы без открытия деталки.
+- Редизайн всей таблицы заказов.
+
+## Решение (утвержденный вариант A)
+
+### 1) Маркер в списке заказов
+
+В `client/src/pages/admin-orders/ui/AdminOrdersPage.tsx` добавить короткий бейдж `Цена не подтверждена` для строк, где:
+
+- `status === 'PENDING_PAYMENT'`
+- `deliveryType === 'delivery'`
+- `deliveryFeeLocked === false`
+
+Размещение: в колонке `ID` рядом с коротким номером заказа (`o.id.slice(-8)`), чтобы не расширять таблицу и чтобы сигнал был виден до открытия деталки.
+
+### 2) Быстрая смена статуса в деталке заказа
+
+В `client/src/features/order-detail/ui/OrderDetailContent.tsx` заменить текущий `Select` "Сменить статус" на набор кнопок быстрых переходов:
+
+- Источник переходов остается прежним: `getAdminNextOrderStatuses(detail.status, detail.deliveryType)`
+- Для каждого допустимого статуса рендерится отдельная кнопка
+- Клик вызывает текущую мутацию `setAdminOrderStatus` через `statusMut.mutate(next)`
+
+Поведение кнопок:
+
+- Пока мутация выполняется (`statusMut.isPending`) все кнопки отключены
+- Если доступных переходов нет — показываем текст `Статус финальный, смена недоступна`
+- Для `CANCELLED` использовать визуально менее акцентную кнопку (`outlined`), чтобы снизить риск случайного нажатия
+
+## Архитектурные границы и переиспользование
+
+- Используем существующие данные `deliveryFeeLocked`, `status`, `deliveryType`.
+- Правила переходов не дублируем в UI, берем из `getAdminNextOrderStatuses`.
+- API слой (`client/src/entities/order/api/admin-order-api.ts`) без изменений.
+- React Query инвалидация сохраняется текущая:
+  - `['admin', 'orders']`
+  - `['admin', 'orders', 'detail']`
+  - `['admin', 'orders', 'summary']`
+
+## Поток данных
+
+1. Страница списка получает `items` из `fetchAdminOrders`.
+2. Для каждой строки вычисляется `needsPriceApproval`.
+3. Если `needsPriceApproval === true`, отображается бейдж `Цена не подтверждена`.
+4. В деталке рассчитывается `nextStatuses`.
+5. Клик по кнопке статуса вызывает `statusMut`.
+6. После успеха инвалидация обновляет список/деталку/summary; маркер в списке исчезает автоматически, когда условие перестает выполняться.
+
+## Обработка ошибок
+
+- Ошибка смены статуса: показать локальный `Alert` в деталке с текстом `Не удалось сменить статус`, дать возможность повторить действие.
+- Ошибка загрузки списка: сохранить текущее поведение (`Не удалось загрузить заказы.`).
+- Пустой список переходов: показать явное сообщение о финальном статусе.
+
+## Тестирование
+
+Минимальный набор:
+
+1. Unit: проверка условия `needsPriceApproval`.
+2. Component (`OrderDetailContent`):
+   - рендерит кнопки только допустимых переходов
+   - вызывает `setAdminOrderStatus` при клике
+   - блокирует кнопки в pending-состоянии
+3. Component/Smoke (`AdminOrdersPage`):
+   - показывает `Цена не подтверждена` для целевых заказов
+   - не показывает бейдж для остальных
+
+## Критерии готовности
+
+- В списке заказов видно короткий маркер `Цена не подтверждена` для релевантных заказов.
+- В деталке смена статуса выполняется через быстрые кнопки допустимых переходов.
+- Список и деталка синхронизируются после успешной смены статуса.
+- Для `CANCELLED` используется менее акцентный стиль кнопки.
+- Проходят `npm run lint` и `npm run format:check` в `client`.
+
+## План изменений по файлам
+
+- `client/src/pages/admin-orders/ui/AdminOrdersPage.tsx` — маркер `Цена не подтверждена` в строках списка.
+- `client/src/features/order-detail/ui/OrderDetailContent.tsx` — замена select на быстрые кнопки.
+- (опционально) `client/src/shared/lib/` — небольшой хелпер `needsPriceApproval`, если нужно переиспользование или unit-тест вне компонента.
+
+## Риски и меры
+
+- Риск перегруза UI в деталке при большом количестве кнопок: низкий, так как число допустимых переходов обычно 1-2.
+- Риск случайного нажатия на отмену: снижается стилем `outlined` для `CANCELLED`.
+- Риск расхождения логики переходов: отсутствует, т.к. используется единый источник `getAdminNextOrderStatuses`.
