+# Управление сервером из веб-интерфейса
+
+В меню админки доступны **Обновления** (`/admin/updates`) и **Конфигурация**
+(`/admin/config`). Клиентские APK и desktop-сборки по-прежнему раздаются через
+существующий механизм `appupdate`; источники обновления сервера от него независимы.
+
+## Установка на существующий сервер
+
+После получения версии с управлением сервером выполните на Linux-хосте:
+
+```bash
+cd /opt/pipu-music/deploy
+sudo bash ./install-management.sh
+./update.sh main   # либо тег версии, содержащей эту возможность
+```
+
+Новая установка через `sudo ./install.sh` устанавливает агент автоматически.
+Нужны systemd, Python **3.10+**, Git, Bash, `flock` (util-linux) и Docker Compose
+**2.24+**. Compose должен поддерживать несколько `--env-file` и тег `!reset`
+из существующего TLS-overlay. Агент выполняется от root, чтобы запускать Compose
+и обращаться к данным развёртывания; API продолжает работать без root и без Docker socket.
+
+Скрипт создаёт `pipu-management.service`, копирует агент вне Git-checkout в
+`/usr/local/lib/pipu/server-agent.py`, создаёт `deploy/config.local` и общий каталог
+`${PIPU_DATA}/management` с владельцем UID 65532. Последний монтируется только в API.
+Приватные настройки источников, состояние, аудит и журналы лежат в
+`/var/lib/pipu-management`, доступном только root. Нужен доступ этого пользователя
+к origin; SSH-ключи и known_hosts для приватных репозиториев настройте на хосте.
+Пароли и токены в URL источников не принимаются.
+
+После успешного обновления агент автоматически заменяет свою установленную копию
+из нового checkout и перезапускается, сохранив итоговый статус. Для ручной установки
+нового кода можно повторно запустить `install-management.sh`.
+Во время выполняющейся операции не перезапускайте его: systemd остановит дочерние
+процессы. После прерывания/перезагрузки задача помечается ошибкой, а не успехом.
+
+## Права
+
+Администратор всегда может управлять обновлениями. В меню действий пользователя
+на странице **Пользователи** он может выдать и забрать право **Управление
+обновлениями** (`manages_updates`). Право действует независимо от роли и проверяется
+на сервере при каждом запросе. Оно позволяет изменять источники, видеть журнал
+и запускать обновление. Пользователь с этим правом получает ссылку на обновления,
+но не получает доступ к пользователям, конфигурации или остальным действиям админа.
+
+Выдавайте это право доверенным операторам: обновление запускает код выбранного
+совместимого репозитория на хосте. Только администраторы могут просматривать,
+сохранять и применять конфигурацию. Выдача/отзыв права записываются в `audit_log`;
+операции агента с UUID инициатора — в его приватный `audit.jsonl` без значений секретов.
+
+## Обновления
+
+При первом обращении автоматически добавляется текущий `git remote origin`.
+Можно создавать, редактировать и удалять источники; хотя бы один должен остаться.
+Поддерживаются совместимые Git-репозитории Pipu через HTTP(S) и SSH.
+
+* **Последний релиз** — значение по умолчанию: максимальный стабильный тег SemVer
+  `vMAJOR.MINOR.PATCH` (также допускается без `v`), без `-rc.N`.
+* **Выбрать версию** — конкретный релизный тег, включая release candidate.
+* **main** — текущий commit ветки main.
+
+Обновления устанавливаются только по нажатию кнопки и после подтверждения.
+Перед запуском агент повторно читает refs и фиксирует SHA; update.sh проверяет,
+что полученный commit совпадает. Выбранный источник не перезаписывает origin
+и не смешивает его теги с тегами другого репозитория. Git checkout с локальными
+изменениями отклоняется. Защита update.sh от downgrade сохраняется: откат
+выполняется вручную с `PIPU_ALLOW_DOWNGRADE=1` после проверки совместимости БД.
+
+Выполнение, ограниченный хвост журнала и итоговый статус доступны на странице.
+Можно закрыть браузер или переждать перезапуск API: работа продолжается на хосте.
+Полные логи остаются приватными; для интерфейса известные секреты маскируются.
+Одновременно агент допускает только одну операцию обновления/применения.
+Резервная копия и откат схемы БД автоматически не выполняются.
+
+## Конфигурация
+
+Реестр поддерживаемых параметров находится в `deploy/config.schema.json`:
+API, общие параметры сервисов, рекомендатель и развёртывание. Добавляя параметр
+в конфигурацию сервиса, обновите реестр; для рекомендателя/агента хранилища также
+проверьте передачу через Compose. Пути томов, сгенерированный DATABASE_URL и
+некоторые служебные параметры показаны для просмотра и меняются на хосте.
+Страница не является произвольным редактором nginx/Caddy/YAML-файлов.
+
+Приоритет при запуске через скрипты:
+
+1. Явные переменные окружения Compose и значения из `deploy/.env`.
+2. `deploy/config.local`.
+3. Встроенные значения по умолчанию.
+
+Для интерполяции Compose скрипты передают `--env-file config.local --env-file .env`.
+У API порядок `env_file: [config.local, .env]`; рекомендатель и storage-agent получают
+только необходимые им переменные через `environment`. При ручном запуске Compose
+сохраняйте эти флаги, иначе параметры интерполяции из config.local не подхватятся.
+Страница показывает ожидаемое значение после применения, а не утверждает, что
+работающий процесс уже перечитал сохранённый файл. Окружение shell запуска Compose
+тоже может перекрывать интерполяцию; для агента используется окружение systemd.
+
+В интерфейсе видны локальное значение, значение из `.env` и источник приоритета.
+Если ключ уже есть в `.env`, изменение его в config.local сохраняется, но не
+перекрывает `.env` — интерфейс прямо сообщает об этом. Чтобы управлять таким ключом
+через страницу, удалите его строку из `.env` на хосте. Секреты не возвращаются в API
+открытым текстом: поле без изменений сохраняет прежний секрет, ввод заменяет,
+**Сбросить локальное** удаляет только значение из config.local.
+
+Сохранение атомарно, с правами 0600 и проверкой ревизии: устаревшая форма не затрёт
+правки другого администратора. Перед сохранением проверяются типы и Compose;
+при ошибке прежний файл восстанавливается. Произвольные ключи, переводы строк
+и изменение служебных параметров отклоняются. Сохраняемые значения трактуются
+буквально: подстановки shell не выполняются.
+
+Кнопка **Применить и перезапустить** отдельно подтверждает пересоздание контейнеров.
+Агент запускает `apply-config.sh`, ждёт `/readyz` и сохраняет результат. Если сервисы
+не стали готовы, состояние — ошибка; исправьте config.local или восстановите его
+на хосте. Автоматического отката конфигурации после неудачного применения нет.
+
+Диагностика:
+
+```bash
+sudo systemctl status pipu-management.service
+sudo journalctl -u pipu-management.service -n 100
+cd /opt/pipu-music/deploy
+docker compose --env-file config.local --env-file .env logs api
+```
+
+Проверки разработки: `python3 -m unittest discover -s deploy -p 'test_*.py'`,
+`go test ./internal/auth ./internal/management` из `services/api`, а также
+`pnpm --filter @pipu/web test:e2e e2e/server-management.spec.ts`.
