 ## КРИТИЧЕСКИЕ ИСПРАВЛЕНИЯ
 
-### Migrations Strategy
+### Migrations Strategy - Чистый Alembic
-**Решение**: Миграции запускаются в Dockerfile перед стартом сервера
+**Решение**: Только Alembic управляет схемой БД, без `create_all()`
 **Файлы**:
+- `backend/alembic/versions/2025_12_31_1400-001_initial_schema.py` - инициализирующая миграция (users, folders, assets, shares)
 - `backend/Dockerfile:34` - `alembic upgrade head` перед uvicorn
-- `backend/Dockerfile:25-26` - Copy alembic files to container
+- `backend/main.py:17` - убран вызов `init_db()` (только Alembic)
-- Удален `run_migrations()` из кода приложения (clean separation)
+- `backend/database.py:53` - `init_db()` помечен WARNING (только для тестов)
