+## 8. Авторизация (вход через Telegram)
+
+
+Авторизация **через Telegram** с **cookie-сессиями** (HttpOnly, Secure, SameSite=None).
+
+
+Все auth-эндпоинты должны поддерживать CORS с `credentials: true`.
+
+
+### Процесс авторизации
+
+
+```
+1. Пользователь нажимает «Оформить заказ» → не авторизован → показывается диалог входа
+2. Нажимает «Войти через Telegram» → открывается https://t.me/{bot}?start=auth_{callback}
+3. Пользователь запускает бота в Telegram
+4. Бот отправляет данные пользователя → бэкенд /auth/telegram/callback
+5. Бэкенд создаёт сессию → устанавливает Set-Cookie
+6. Фронтенд опрашивает GET /auth/session каждые 3 секунды
+7. Сессия обнаружена → диалог закрывается → оформление заказа продолжается
+```
+
+
+---
+
+
+### `GET /auth/session` — Проверить текущую сессию
+
+
+**Запрос:** Только cookie (сессионная cookie, установленная бэкендом).
+
+
+**Ответ `200`** (авторизован):
+```json
+{
+  "sessionId": "sess_abc123",
+  "telegramUserId": 123456789,
+  "username": "john_doe",
+  "displayName": "John Doe",
+  "active": true,
+  "expiresAt": "2026-03-01T12:00:00Z"
+}
+```
+
+
+**Ответ `200`** (сессия истекла):
+```json
+{
+  "sessionId": "sess_abc123",
+  "telegramUserId": 123456789,
+  "username": "john_doe",
+  "displayName": "John Doe",
+  "active": false,
+  "expiresAt": "2026-02-27T12:00:00Z"
+}
+```
+
+
+**Ответ `401`** (нет сессии):
+```json
+{ "error": "No active session" }
+```
+
+
+**Объект AuthSession:**
+
+
+| Поле             | Тип     | Обязат. | Описание                                  |
+|------------------|---------|---------|-------------------------------------------|
+| `sessionId`      | string  | да      | Уникальный ID сессии                      |
+| `telegramUserId` | number  | да      | ID пользователя в Telegram                |
+| `username`       | string? | нет     | @username в Telegram (может быть null)    |
+| `displayName`    | string  | да      | Отображаемое имя (имя + фамилия)          |
+| `active`         | boolean | да      | Действительна ли сессия                   |
+| `expiresAt`      | string  | да      | Дата истечения в формате ISO 8601         |
+
+
+---
+
+
+### `GET /auth/telegram/callback` — Callback авторизации Telegram-бота
+
+
+Вызывается Telegram-ботом после авторизации пользователя.
+
+
+**Тело запроса (от бота):**
+```json
+{
+  "id": 123456789,
+  "first_name": "John",
+  "last_name": "Doe",
+  "username": "john_doe",
+  "photo_url": "https://t.me/i/userpic/...",
+  "auth_date": 1709100000,
+  "hash": "abc123def456..."
+}
+```
+
+
+
+
+Бот должен:
+1. Слушать команду `/start auth_{callbackUrl}`
+2. Извлечь callback URL
