+# Техническая спецификация передачи (Handoff) для бэкенда krona-omnichannel
+
+## 1. Введение и назначение
+
+Данный документ описывает архитектурный контракт взаимодействия между клиентским интерфейсом `krona-front` (модуль `/communications`) и микросервисной бэкенд-платформой `krona-omnichannel`.
+
+Интерфейс спроектирован по принципу **контрактного разделения**: UI обращается к слою `communicationsService`, который в текущей версии предоставляет надёжную локальную модель с реактивным состоянием, полностью совместимую с будущими REST / WebSocket эндпоинтами.
+
+---
+
+## 2. Сопоставление доменных моделей (Domain Mapping)
+
+| Модель `krona-front` | Сущность в `krona-omnichannel` | Описание и соответствие полей |
+|---|---|---|
+| **Conversation** | `ChatSession` / `Thread` | `id: ULID`, `contactId`, `primaryConnector` (enum: `telegram`, `whatsapp`, `vk`, `max`, `email`), `unreadCount: int`, `lastMessage: Message`, `isFavorite: bool`, `assignedUserId: UUID` |
+| **Message** | `MessageRecord` | `id: ULID`, `conversationId`, `direction` (`incoming` / `outgoing`), `text: str`, `timestamp: ISO8601`, `status` (`sent` / `delivered` / `read`), `senderName`, `attachments: Attachment[]`, `isInternal: bool` |
+| **Channel** | `CorporateChannel` | `id: ULID`, `name: str`, `description: str`, `isPrivate: bool`, `membersCount: int`, `pinnedMessageId: ULID`, `unreadCount: int` |
+| **ContactOmnichannel** | `CustomerProfile` / `Party` | `id: ULID`, `name: str`, `avatarUrl: str`, `phone: str`, `email: str`, `company: str`, `role: str`, `isVip: bool`, `isClient: bool`, `linkedDealsCount: int`, `linkedOrdersCount: int`, `channels: ChannelAccount[]` |
+| **RoutingRule** | `OmnichannelRoutingRule` | `id: ULID`, `title: str`, `condition: str`, `assigneeDepartment: str`, `assigneeUser: str`, `enabled: bool` |
+| **QuickReply** | `CannedResponse` | `id: ULID`, `title: str`, `text: str`, `shortcut: str`, `category: str` |
+| **Connector** | `ConnectorIntegration` | `id: enum`, `name: str`, `status` (`connected` / `degraded` / `disconnected`), `pingMs: int`, `accountsCount: int`, `uptimePercent: float` |
+
+---
+
+## 3. Спецификация REST API эндпоинтов
+
+Базовый префикс: `/api/v1/omnichannel`
+
+### 3.1. Мессенджеры и диалоги
+- `GET /conversations?connector={type}&filter={unread|favorite}&search={query}&limit=50&cursor={ulid}`
+  - Возвращает список диалогов с пагинацией по курсору ULID.
+- `GET /conversations/{id}/messages?limit=100&before={messageId}`
+  - Возвращает историю сообщений чата.
+- `POST /conversations/{id}/messages`
+  - Тело запроса:
+    ```json
+    {
+      "text": "Здравствуйте, коммерческое предложение во вложении",
+      "attachments": [
+        { "name": "offer_2026.pdf", "url": "https://storage.krona.ru/...", "size": "2.4 MB" }
+      ],
+      "isInternal": false
+    }
+    ```
+- `PATCH /conversations/{id}/read`
+  - Сброс счётчика непрочитанных для пользователя.
+- `POST /conversations/{id}/actions/crm-deal`
+  - Создание быстрой сделки в CRM из контекста переписки.
+
+### 3.2. Внутрикорпоративные каналы
+- `GET /channels` — список каналов компании.
+- `POST /channels` — создание нового канала.
+- `GET /channels/{id}/messages` — получение ленты канала.
+- `POST /channels/{id}/messages/{messageId}/reactions`
+  - Тело запроса: `{ "emoji": "👍" }` (добавить или снять реакцию).
+
+### 3.3. Корпоративная почта (Email)
+- `GET /email/messages?mailbox={id}&folder={inbox|sent|trash}&search={query}`
+- `POST /email/messages/send`
+  - Тело: `{ "from": "...", "to": "...", "subject": "...", "body": "...", "attachments": [] }`
+
+### 3.4. Диагностика коннекторов и VPN Gateway
+- `POST /connectors/{id}/ping`
+  - Запускает проверку связи с шлюзом соответствующей платформы, возвращает `{ "status": "connected", "latencyMs": 42 }`.
+- `GET /gateway/status`
+  - Возвращает статус VPN / Sing-box тоннеля (node, uptime, protocol, totalTraffic).
+
+---
+
+## 4. Спецификация событий реального времени (WebSocket)
+
+Подключение: `wss://krona-platform.ru/ws/omnichannel?token={jwt}`
+
+### Входящие события с бэкенда на фронтенд:
+1. `message.received` — поступление нового сообщения от клиента из внешнего мессенджера (Telegram, WhatsApp, VK, MAX, Email).
+   ```json
+   {
+     "event": "message.received",
+     "data": {
+       "conversationId": "01J9...",
+       "message": {
+         "id": "01J9...",
+         "direction": "incoming",
+         "text": "Подтверждаю оплату счета",
+         "senderName": "Иван Петров",
+         "connector": "telegram",
+         "timestamp": "2026-09-11T16:20:00Z"
+       }
+     }
+   }
+   ```
+2. `message.status_updated` — обновление статуса доставки/прочтения (`delivered`, `read`).
+3. `channel.reaction_updated` — синхронизация реакций в каналах в реальном времени.
+4. `connector.health_changed` — изменение статуса коннектора или сетевого шлюза.
+
+---
+
+## 5. Webhook-контракты внешних коннекторов
+
+Бэкенд `krona-omnichannel` принимает вебхуки от внешних систем:
+- `POST /webhooks/telegram/{botToken}`
+- `POST /webhooks/whatsapp/{tenantId}`
+- `POST /webhooks/vk/{communityId}`
+- `POST /webhooks/max/{gatewaySecret}`
+- `POST /webhooks/mail/{inboundKey}`
+
+Все вебхуки преобразуются нормализатором `krona-omnichannel` в каноническую структуру `MessageRecord` и транслируются в UI через WebSocket.

+# Использование UI-библиотеки krona-library в krona-front
+
+## 1. Архитектурный принцип
+
+В рамках технического задания **запрещено копирование компонентов из `krona-library` в `krona-front`**.
+Все компоненты, токены и темы дизайна подключаются как внешние пакетные зависимости:
+- `@krona/tokens` и `@krona/tokens.css`
+- `@krona/themes` и `@krona/themes.css`
+- `@krona/ui`
+
+В директории `src/` проекта `krona-front` нет ни одного форкнутого или дублированного файла из `krona-library/packages/ui/src/components/`.
+
+---
+
+## 2. Реестр используемых компонентов @krona/ui
+
+| Компонент | Импорт | Где используется в `krona-front` | Передаваемые props и варианты |
+|---|---|---|---|
+| **Tabs** | `import { Tabs } from '@krona/ui'` | `CommunicationsHeader.tsx` | `items`: `[{ id, label, icon, badge }]`, `activeId`, `onChange`, `ariaLabel` |
+| **ConnectorPill** | `import { ConnectorPill } from '@krona/ui'` | `MessengersView.tsx` | `active`, `onClick`, `count`, `alertCount`, `icon`, `children` |
+| **MessageBubble** | `import { MessageBubble } from '@krona/ui'` | `MessengersView.tsx`, `ChannelsView.tsx` | `direction` (`'incoming' | 'outgoing'`), `senderName`, `timestamp`, `status` (`'sent' | 'delivered' | 'read'`), `connector`, `isInternal`, `attachments`, `avatarUrl` |
+| **Card** | `import { Card } from '@krona/ui'` | `MessengersView.tsx`, `SettingsView.tsx`, `ChannelsView.tsx` | `variant` (`'default' | 'muted' | 'interactive'`), `padding` (`'sm' | 'md' | 'lg'`), `header`, `footer`, `children` |
+| **Modal** | `import { Modal } from '@krona/ui'` | `Modals.tsx` (ComposeEmail, NewChannel, QuickReply, NewContact) | `isOpen`, `onClose`, `title`, `size` (`'sm' | 'md' | 'lg' | 'xl'`), `footer`, `children` |
+| **Button** | `import { Button } from '@krona/ui'` | Во всех представлениях `/communications` | `variant` (`'primary' | 'secondary' | 'ghost' | 'danger'`), `size` (`'sm' | 'md' | 'lg'`), `disabled`, `icon`, `onClick` |
+| **Input** | `import { Input } from '@krona/ui'` | Поиск, модальные окна, фильтры | `label`, `placeholder`, `error`, `leftIcon`, `value`, `onChange` |
+| **Badge** | `import { Badge } from '@krona/ui'` | Карточка контакта, список писем, каналы | `variant` (`'default' | 'primary' | 'success' | 'warning' | 'danger' | 'outline'`), `size` (`'sm' | 'md'`), `children` |
+| **Avatar** | `import { Avatar } from '@krona/ui'` | Список диалогов, заголовок чата, участники | `name`, `src`, `size` (`'sm' | 'md' | 'lg'`), `status` (`'online' | 'offline' | 'busy'`) |
+
+---
+
+## 3. Потребление CSS токенов дизайн-системы V3
+
+В `src/index.css` подключены:
+```css
+@import '@krona/tokens.css';
+@import '@krona/themes.css';
+```
+
+В кодовой базе `krona-front` при оформлении коммуникаций используются исключительно семантические переменные:
+- **Цвета фона:** `var(--krona-bg-workspace)`, `var(--krona-surface)`, `var(--krona-surface-hover)`, `var(--krona-surface-muted)`, `var(--krona-surface-selected)`
+- **Брендовые цвета:** `var(--krona-primary)`, `var(--krona-primary-hover)`, `var(--krona-primary-active)`, `var(--krona-primary-soft)`
+- **Границы:** `var(--krona-border)`, `var(--krona-border-subtle)`, `var(--krona-border-focus)`
+- **Текст:** `var(--krona-text-primary)`, `var(--krona-text-secondary)`, `var(--krona-text-muted)`, `var(--krona-text-inverse)`
+- **Статусы:** `var(--krona-status-success)`, `var(--krona-status-warning)`, `var(--krona-status-danger)`, `var(--krona-status-info)`
+
+---
+
+## 4. Поддержка тем оформления
+
+Root элемент приложения (`document.documentElement`) управляется через `src/stores/theme.ts`:
+- `data-krona-theme="noble-green"`
+- `data-krona-theme="parchment-light"`
+- `data-krona-theme="graphite-forest-dark"`
+
+Каждая тема активирует свой набор CSS-переменных из `@krona/themes.css`, обеспечивая бесшовное переключение всей цветовой палитры интерфейса.
