- Зачем: - генератор должен переживать рестарт без потери популяции пользователей и коротко прерванных активных визитов. - Что: - добавлен компактный state v2 для популяции, активных визитов и остатка бюджета рождений. - сервис генератора переведён на единый тиковый поток с сохранением и восстановлением состояния. - добавлена безопасная деградация для старого state v1 и битого state v2. - покрыты короткий и долгий простой, reset состояния и валидация вложенного state. - Проверка: - uv run --with-requirements generator/requirements.txt pytest generator/tests -q. - git diff --check.
