 Контейнер API сам выполняет `alembic upgrade head`, затем идемпотентный seed. PostgreSQL хранит данные в именованном volume `postgres_data`, а MinIO — в `minio_data`. Compose ожидает readiness PostgreSQL и MinIO перед API, а API-контейнер проверяет `/ready`. Официальный импорт по умолчанию необязателен; при включённом scheduler установите `OFFICIAL_IMPORT_REQUIRED=true`, тогда отсутствующий, неуспешный или просроченный запуск сделает readiness отрицательным.
 
+API и scheduler пишут по одной JSON-записи на событие. HTTP-лог содержит только сгенерированный `request_id`, метод, путь без query string, статус и длительность; IP, заголовок авторизации и пользовательский payload не журналируются. `X-Request-ID` возвращается клиенту. Стандартный access-log Uvicorn отключён. Уровень управляется `LOG_LEVEL`.
