Снимок хранится в PostgreSQL после каждого подтверждённого действия. Это
`model_dump` сохраняемой части сессии (`PersistedSession`): сокеты, аудиобуферы
и объекты моделей в неё не входят и после перезапуска процесса собираются
заново (`rebuild_live`).

занятия, а плохой снимок реестр и восстановление узла логируют и пропускают.
