+```
+
+### JavaScript
+
+**Загрузка файла:**
+```javascript
+const formData = new FormData();
+formData.append('file', fileInput.files[0]);
+
+const response = await fetch('http://localhost:8080/api/demo/upload', {
+  method: 'POST',
+  body: formData
+});
+
+const result = await response.json();
+const sessionId = result.sessionId;
+```
+

+result = response.json()
+session_id = result['sessionId']
+```
+
+---
+
+## Обработка Ошибок
+
+### 400 Bad Request - Файл слишком большой
+```json
+{
+  "status": "FAILED",
+  "message": "File too large. Max size: 50 MB"
+}
+```
+
+**Решение:** Загрузите файл меньшего размера
+
+### 400 Bad Request - Неподдерживаемый тип файла
+```json
+{
+  "status": "FAILED",
+  "message": "File type not supported for demo"
+}
+```
+
+**Решение:** Используйте поддерживаемый тип файла
+
+### 400 Bad Request - Лимит на день
+```json
+{
+  "status": "FAILED",
+  "message": "Daily limit reached. Max 10 files per day"
+}
+```
+
+**Решение:** Подождите до следующего дня или зарегистрируйтесь
+
+### 404 Not Found - Сессия не найдена
+```json
+{
+  "status": "ERROR"
+}
+```
+
+**Решение:** Проверьте правильность sessionId
+
+### 500 Internal Server Error
+```json
+{
+  "status": "FAILED",
+  "message": "Upload failed: ..."
+}
+```
+
+**Решение:** Попробуйте позже или свяжитесь с поддержкой
+
+---
+
+## Cleanup-сервис (важное объяснение)
+
+### Что делает Cleanup-сервис?
+
+Это автоматизированный сервис, который периодически:
+
+1. **Ищет истекшие сессии** (старше 24 часов)
+2. **Удаляет файлы из S3** для экономии места
+3. **Помечает сессии как CLEANED** в БД
+4. **Удаляет FAILED сессии** (старше 1 часа)
+
+### Почему это нужно?
+
+- **Экономия дискового пространства** - S3 стоит денег
+- **Соблюдение GDPR/приватности** - данные не лежат вечно
+- **Производительность БД** - не растёт бесконечно
+- **Безопасность** - временные данные не остаются в системе
+
+### Как это работает?
+
+```
+Каждые 30 минут:
+┌─────────────────────────────────────┐
+│ 1. Найти истекшие сессии            │
+│    WHERE expiresAt <= NOW()         │
+└─────────────────────────────────────┘
+                 ↓
+┌─────────────────────────────────────┐
+│ 2. Для каждой сессии:              │
+│    - Удалить из S3                  │
+│    - Обновить статус = CLEANED      │
+└─────────────────────────────────────┘
+```
+
+### В конфиге (application.yaml):
+
+```yaml
+demo:
+  max-file-size: 52428800      # 50 MB
+  max-files-per-day: 10        # макс 10 файлов в день
+  s3-path: demo/               # путь в S3
+  session-ttl-hours: 24        # 24 часа жизни сессии
+  cleanup-interval: 30         # cleanup каждые 30 минут
+  failed-cleanup-interval: 60  # очистка FAILED каждый час
+```
+
+---
+
+## Статистика и Мониторинг
+
+### Метрики для отслеживания
+
+```java
+// Количество активных демо-сессий
+long activeSessions = demoCleanupService.getActiveDemoSessionsCount();
+
+// Общий размер демо-данных в S3
+long dataSizeInBytes = demoCleanupService.getActiveDemoDataSize();
+long dataSizeInMB = dataSizeInBytes / (1024 * 1024);
+```
+
+### Логирование
+
+Все операции логируются:
+```
+[INFO] Demo upload started for IP: 192.168.1.1
+[INFO] File uploaded to S3 at: demo/550e8400.../test.jpg
+[INFO] Starting search for session: 550e8400-e29b-41d4...
+[INFO] Demo cleanup completed. Cleaned 5 sessions
+```
+
+---
+
+## Best Practices для Frontend
+
+1. **Показывайте progress** - используйте `progressPercentage`
+2. **Обрабатывайте ошибки** - проверяйте `status` == "FAILED"
+3. **Очищайте сессии** - вызывайте `/cleanup` перед уходом
+4. **Не перезагружайте** - максимум 10 файлов в день
+5. **Таймауты** - сессия истекает через 24 часа
+
+---
+
+## Интеграция на лэндинге
+
+### Step 1: Drag & Drop зона
+```html
+<div id="dropZone" class="upload-area">
+  Перетащите файл сюда или нажмите
+  <input type="file" id="fileInput" />
+</div>
+```
+
+### Step 2: Загрузка
+```javascript
+const upload = async (file) => {
+  const formData = new FormData();
+  formData.append('file', file);
+  
+  const res = await fetch('/api/demo/upload', {
+    method: 'POST',
+    body: formData
+  });
+  
+  return res.json();
+};
+```
+
+### Step 3: Демо поиска
+```javascript
+const startDemo = async (sessionId) => {
+  const res = await fetch(`/api/demo/search/${sessionId}`, {
+    method: 'POST'
+  });
+  
+  return res.json();
+};
+```
+
+### Step 4: Очистка
+```javascript
+const endDemo = async (sessionId) => {
+  await fetch(`/api/demo/cleanup/${sessionId}`, {
+    method: 'DELETE'
+  });
+};
+```

+
+## FAQ
+
+**Q: Мой файл исчезает через 24 часа?**  
+A: Да, это запланировано. Используйте полную версию для постоянного хранения.
+
+**Q: Могу ли я загрузить больше 10 файлов?**  
+A: Только если зарегистрируетесь. Демо имеет лимиты в целях защиты.
+
+**Q: Почему мне не дают загрузить файл больше 50 MB?**  
+A: Это демо, которое работает на общих ресурсах. Полная версия поддерживает файлы до 1 GB.
+
+**Q: Где хранятся мои файлы?**  
+A: В AWS S3, в отдельной папке `demo/`. Никто другой не может получить к ним доступ.
+
+**Q: Что если мой IP заблокирован?**  
+A: Попробуйте через день или зарегистрируйтесь для безлимитного доступа.

+## 🔒 Ограничения и Защита
+
+### Размеры Файлов
+```
+Max размер: 50 MB
+Типы: image/jpeg, image/png, application/pdf, audio/mp3, etc.
+Проверка MIME type: обязательна
+```
+
+### Rate Limiting
+```
+По IP адресу:
+- 10 файлов в день
+- Проверка каждые 24 часа
+- Блокировка при превышении
+```
+
+### Безопасность
+```
+✅ IP-based rate limiting
+✅ Валидация типов файлов
+✅ Проверка размера на бэкенде
+✅ Авторизация по IP (пользователь может видеть только свои файлы)
+✅ Автоматическое удаление через 24 часа
+✅ Обработка ошибок S3 без падения сервиса
+```

+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": [
+        "s3:PutObject",
+        "s3:GetObject",

+```bash
+mvn test -Dtest=DemoSessionServiceTest
+mvn test -Dtest=DemoCleanupServiceTest
+mvn test -Dtest=DemoControllerTest
+```
+
+---
+
+## 📈 Масштабирование
+
+### Текущие возможности
+- ~1000 активных демо-сессий одновременно
+- ~50 GB демо-данных в S3
+- ~1000 операций в минуту
+
+### Если нужно больше:
+1. **Увеличить cleanup интервал** - если много одновременных пользователей
+2. **Добавить Redis** - для кэширования информации о сессиях
+3. **Использовать S3 Lifecycle** - для автоматического удаления файлов старше 30 дней
+4. **Шардирование по IP** - если очень много юзеров
+
+---
+
+## 🐛 Обработка Ошибок
+
+### Валидация
+```
+❌ File too large → 400 Bad Request
+❌ Unsupported file type → 400 Bad Request
+❌ Daily limit reached → 400 Bad Request
+❌ Empty file → 400 Bad Request
+```
+
+### Авторизация
+```
+❌ Unauthorized IP access → 403 Forbidden
+❌ Session not found → 404 Not Found
+```
+
+### S3 Ошибки
+```
+⚠️ S3 upload failure → сессия помечена FAILED, но не бросает исключение
+⚠️ S3 delete failure → cleanup продолжается, но логируется
+```
+

+
+## 🔍 Мониторинг
+
+### Метрики для сбора
+```java
+// Active sessions
+demoCleanupService.getActiveDemoSessionsCount()
+
+// Storage usage
+demoCleanupService.getActiveDemoDataSize()
+
+// Logs
+grep "Demo upload" application.log | wc -l  // количество загрузок
+grep "Demo cleanup" application.log | wc -l  // количество очисток
+```
+
+### Prometheus метрики (опционально)
+```
+demo_sessions_active{} - количество активных сессий
+demo_storage_bytes{} - размер демо-данных
+demo_uploads_total{} - всего загрузок
+demo_cleanups_total{} - всего очисток
+```
+
+---
+
+## ✨ Особенности Cleanup-сервиса
+
+### Почему это важно?
+```
+1. S3 стоит денег → нужно удалять старые файлы
+2. GDPR требует удаления → временные данные должны удаляться
+3. БД растёт → сессии должны очищаться
+4. Безопасность → демо-данные не должны лежать вечно
+```
+
+### Как это работает?
+```
+@Scheduled(fixedDelay = 1800000)  // каждые 30 минут
+public void cleanupExpiredSessions() {
+  1. Найти WHERE expiresAt <= NOW()
+  2. Для каждой: удалить из S3
+  3. Обновить статус = CLEANED
+  4. Залогировать результаты
+}
+```
+
+### Отказоустойчивость
+```
+✅ Если S3 недоступен - продолжаем работу, логируем
+✅ Если БД недоступна - scheduler пересчитает позже
+✅ Если исключение - перехватываем и логируем
+✅ Максимальная защита от потери данных
+```

+## 🚦 Next Steps
+
+1. **Добавить миграцию Flyway** для создания таблицы `demo_sessions`
+2. **Настроить S3 bucket** с правами доступа
+3. **Запустить тесты** - убедиться что всё работает
+4. **Сделать фронтенд** - drag & drop, upload progress, результаты
+5. **Настроить мониторинг** - какой процент юзеров конвертируется
+6. **Добавить analytics** - откуда приходят юзеры для демо
+
