 # Развёртывание
 
+После копирования `.env.example` обязательно заполните `STANDALONE_TENANT_ID` идентификатором организации (ULID) из Krona Business Platform. Значения по умолчанию нет; прежняя заглушка `01J00000000000000000000000` не подходит для Compose или пилота. Для первого запуска `deploy/pilot/setup.sh` передайте этот ID через переменную окружения: установщик проверит его и сохранит в своём `.env`. При повторном запуске проверяется существующий `.env`. Для уже заполненного пилота нельзя просто заменить ID: сначала нужна резервная копия, проверка восстановления и перенос tenant-данных.
+
 Локально скопируйте `.env.example` в `.env` и выполните `docker compose up --build`. Compose последовательно проверит PostgreSQL, создаст или обновит отдельную роль `krona_staff_app` с `NOSUPERUSER NOBYPASSRLS`, выполнит миграции ролью `krona_migrator` и только затем запустит приложение. Runtime-контейнер не получает пароль или URL мигратора. Redis и object storage не включаются до появления реального сценария очередей или файлов.
 
 Для обновления старого Docker volume, созданного версией с ролью `krona_staff`, задайте в `.env` `POSTGRES_MIGRATION_USER=krona_staff` и прежний `POSTGRES_MIGRATION_PASSWORD`, затем выполните обычный `docker compose up --build`. Сохраняйте эту роль владельцем миграций для данного volume: автоматического переименования владельца существующей базы нет, а перенос владения требует отдельного DBA-плана с повторной настройкой default privileges.
