- Зачем: - нужен основной ручной интерфейс стенда для backfill/import/check без консольной матрицы переменных. - Что: - добавлен DAG generator_control с параметрами Airflow, ветвлением операций и ожиданием ETL. - вынесена общая логика запуска и предпроверок генератора для Airflow. - обновлены compose-настройки, зависимости, тесты и документация по пульту. - Проверка: - uv run --with pytest --with-requirements generator/requirements.txt pytest generator/tests -q. - docker compose config --quiet.
