 ## КРИТИЧЕСКИЕ ИСПРАВЛЕНИЯ
 
-### Auto-Migration Fix (database.py)
+### Migrations Strategy
-**Проблема**: RuntimeWarning: coroutine 'run_async_migrations' was never awaited
+**Решение**: Миграции запускаются в Dockerfile перед стартом сервера
-**Причина**: Alembic - синхронная библиотека, но получала async database URL
-**Решение**: Конвертация async URL в sync перед передачей в Alembic
-- `sqlite+aiosqlite://` → `sqlite:///`
-- `postgresql+asyncpg://` → `postgresql://`
-
 **Файлы**:
-- `backend/src/app/infra/database.py:78-80` - URL conversion
+- `backend/Dockerfile:34` - `alembic upgrade head` перед uvicorn
 - `backend/Dockerfile:25-26` - Copy alembic files to container
+- Удален `run_migrations()` из кода приложения (clean separation)
