- Настроена среда на Ubuntu 24.04: проверены Node.js и PostgreSQL, выполнен npm run install:all.

- Пересобран bcrypt под Linux (npm rebuild / переустановка), после чего успешно отработал prisma seed (созданы пользователи и загружены СБЦ).
- Создано виртуальное окружение backend/pdf_generator/venv и установлены зависимости из requirements.txt; backend настроен использовать python из этого venv при генерации PDF (pdf-python.service.ts).
- Переключён AI-провайдер с LMStudio на Ollama: в ai.service.ts добавлена поддержка Ollama, в .env и .env.example выставлены AI_PROVIDER=ollama, OLLAMA_API_URL=http://192.168.88.160:11434 и OLLAMA_MODEL=gemma3n:e4b.
- Перезапущены backend и frontend; проверено, что API /api/health отвечает, а Ollama (gemma3n:e4b) успешно обрабатывает chat-запросы.
