+# Подключение будущего бота MAX
+
+Серверная часть готова к подключению. Сам бот ещё не создан, секреты не заполнены,
+реальная отправка не включена. Изменений интерфейса сайта в этой поставке нет.
+Интеграция уведомляет **самого пациента**; врачебные оповещения остаются в существующем канале проекта.
+
+## Что реализовано
+
+- Одноразовая ссылка для привязки аккаунта MAX к текущему пациенту сайта, срок по умолчанию 10 минут.
+- Подтверждение подключения, `/help`, `/stop`, отключение при остановке или удалении бота в MAX.
+- Нейтральные напоминания из существующего планировщика сайта: тесты, дневник, приём лекарств и другие события outbox.
+- Уведомление о завершении теста: сервер каждые примерно 30 секунд находит новые завершённые
+  `QuestionnaireRecord` и `ScaleResult`, начиная с момента подключения MAX. Незавершённые и старые тесты не отправляются.
+- Постоянная очередь, восстановление после перезапуска, ограниченные повторы при сетевых ошибках и ответах 429/5xx.
+- В сообщении только короткий текст и кнопка на сайт. Ответы, оценки, диагнозы, назначения и ключ входа на сайт
+  в MAX не передаются. Переписка с ботом не сохраняется и не отправляется в LLM.
+
+## 1. Создать бота — будущему владельцу
+
+1. Открыть [MAX для партнёров](https://business.max.ru/) и пройти регистрацию/проверку профиля.
+   Условия допуска зависят от типа владельца; актуальный порядок — в
+   [официальной инструкции подключения](https://dev.max.ru/help/platform_connection).
+2. Создать чат-бота, оформить описание и пройти требуемую MAX модерацию.
+3. В настройках бота получить токен и скопировать имя из его публичной ссылки `https://max.ru/ИМЯ`.
+4. Передать администратору сервера имя бота, а токен — через защищённое хранилище секретов.
+   Токен не нужен в переписке, MR или репозитории.
+
+## 2. Заполнить настройки сервера
+
+Нужны доступная identity/clinical БД проекта, публичный HTTPS-адрес сайта и HTTPS-адрес API на порту 443.
+Входящие POST от MAX должны доходить до API без браузерной CAPTCHA или страницы авторизации.
+Прокси должен передавать заголовок `X-Max-Bot-Api-Secret` и не журналировать тело webhook/Authorization.
+Дополнительные таблицы identity создаются существующим `init_db()` при запуске приложения.
+
+В `.env` сервера (вне Git) заполнить:
+
+```dotenv
+MAX_ENABLED=false
+MAX_BOT_TOKEN=
+MAX_BOT_USERNAME=
+MAX_WEBHOOK_SECRET=
+MAX_WEBHOOK_URL=https://api.example.org/api/v1/webhooks/max
+MAX_SITE_URL=https://patient.example.org/
+MAX_LINK_TTL_SECONDS=600
+# При необходимости — PEM-файл доверенного CA, доступный внутри контейнера:
+MAX_CA_BUNDLE=
+DEMO_CLOCK=false
+```
+
+- `MAX_BOT_USERNAME` — только имя, без `@`, домена или параметров ссылки.
+- `MAX_WEBHOOK_SECRET` — отдельная случайная строка, не токен бота: 32–256 символов из `A–Z a–z 0–9 _ -`.
+  Сгенерировать локально, например `python -c 'import secrets; print(secrets.token_urlsafe(32))'`, сохранить в секреты.
+- `MAX_SITE_URL` ведёт в обычный личный кабинет; не добавлять в адрес ключи доступа или данные пациента.
+- Исходящие запросы идут на `https://platform-api2.max.ru`, токен передаётся заголовком `Authorization`.
+  Верификация TLS всегда включена. Если системе нужен корневой сертификат Минцифры, установить его по
+  официальной инструкции MAX и указать PEM-путь в `MAX_CA_BUNDLE`; не отключать проверку TLS.
+- Переменные должны попасть именно в окружение API-контейнера/процесса, а не только панели сайта.
+  В текущем Compose сервис `app` уже получает `.env` через `env_file`.
+  После изменения окружения пересоздать процесс/контейнер API. Новые зависимости не требуются.
+
+## 3. Проверить и включить
+
+В каталоге проекта, в том же окружении, где работает API:
+
+```sh
+uv run python -m app.channels.max_setup check
+```
+
+Команда проверит токен и совпадение имени бота. Сообщений пользователям она не отправляет.
+Затем установить `MAX_ENABLED=true`, перезапустить API и выполнить:
+
+```sh
+uv run python -m app.channels.max_setup subscribe
+uv run python -m app.channels.max_setup status
+```
+
+`subscribe` регистрирует только заданный webhook с секретом и событиями
+`bot_started`, `message_created`, `bot_stopped`, `dialog_removed`. Старые чужие подписки автоматически
+не удаляются: при переносе сервера владелец должен проверить их отдельно через MAX API.
+`status` проверяет регистрацию адреса; это ещё не проверка доступности сервера из MAX.
+Команды не печатают токены, секрет webhook или сырые ответы платформы.
+
+При запуске через Compose вместо `uv run python ...` использовать
+`docker compose exec app python -m app.channels.max_setup check` (также `subscribe` и `status`).
+После изменения `.env` пересоздать API: `docker compose up -d --build --force-recreate app`.
+
+Запускать один процесс API с MAX на один токен бота: его worker отправляет до одного сообщения в секунду.
+БД защищает очередь от параллельного захвата, но общий лимит скорости нескольких процессов не координируется.
+Планировщик и MAX worker запускаются вместе с FastAPI, отдельный процесс бота не нужен.
+При `MAX_ENABLED=false` сетевых вызовов MAX и фонового worker нет; сайт продолжает обычную работу.
+
+## API для разработчика сайта
+
+В проекте используется ключ текущего пациента, полученный при входе. Для этих ручек передавать его
+как `Authorization: Bearer <patient_token>`; это существующая авторизация прототипа, не новая система SSO.
+Не брать token другого пациента и не публиковать демонстрационные учётные записи для реального использования.
+
+| Метод и путь | Запрос | Ответ |
+|---|---|---|
+| `GET /api/v1/me/notifications/max` | Authorization | `available`, `connected`, `last_delivery` |
+| `POST /api/v1/me/notifications/max/link` | Authorization; JSON `{"consent": true}` | `url`, `expires_at` |
+| `DELETE /api/v1/me/notifications/max` | Authorization | состояние с `connected: false` |
+| `POST /api/v1/webhooks/max` | MAX JSON + `X-Max-Bot-Api-Secret` | `{"success": true}` после записи события |
+
+Поток подключения: пациент явно соглашается на уведомления → сайт получает `url` → открывает ссылку MAX →
+пользователь запускает бота → webhook подтверждает привязку → повторный GET показывает `connected: true`.
+Ссылка одноразовая; новая ссылка отменяет предыдущую. Изначальный ключ пациента не входит в URL MAX.
+Для привязки и доставки дополнительно нужны действующее согласие и подтверждение совершеннолетия в состоянии пациента.
+Активную привязку нельзя молча переназначить другому аккаунту: сначала отключить её.
+
+Коды ошибок: 401 — неизвестный/отсутствующий ключ пациента; 403 — нет согласия или неверный секрет webhook;
+422 — неверный запрос; 413 — webhook больше 64 КиБ; 503 — MAX выключен или хранилище события недоступно.
+Повтор webhook с тем же идентификатором события не создаёт новых отправок. Групповые чаты игнорируются.
+
+`last_delivery`: `queued`, `sending`, `sent`, `failed`, `cancelled` или `null`.
+`sent` означает принятие сообщения API MAX, а не прочтение человеком.
+
+## Пробное подключение после создания бота
+
+1. Войти на сайте синтетическим пациентом и дать необходимые согласия.
+2. Получить ссылку через POST выше (Swagger `/docs` или будущий интерфейс сайта), перейти в MAX и запустить бота.
+3. Убедиться, что GET показывает `connected: true` и приходит подтверждение.
+4. Завершить тест на сайте; примерно через 30 секунд плюс очередь должно прийти сообщение без результатов.
+5. Дождаться события планировщика и проверить нейтральное напоминание с кнопкой на сайт.
+6. Отправить `/stop`: GET должен показать `connected: false`, ожидающие уведомления отменяются.
+7. Повторить подключение новой ссылкой, проверить DELETE через API и остановку бота через интерфейс MAX.
+
+При недоставке проверить настройки и подписку, доступность HTTPS, состояние очереди и коды ошибок в логах.
+`http_401`/`http_403` требуют проверки токена/прав; `http_429` — ожидания; `transport` — сети/TLS;
+`failed` после шести попыток требует вмешательства администратора. Детали ответов и идентификаторы в логи не выводятся.
+Отключение отменяет очередь; уже принятый MAX запрос отозвать невозможно.
+
+## Гарантии и ограничения
+
+Очередь и подтверждения событий сохраняются в identity БД. Клинические записи остаются в clinical БД.
+Для событий завершения тестов БД повторно просматривается после перезапуска; ключи уведомлений предотвращают
+повторную постановку. Напоминания используют существующий механизм outbox/повторов планировщика.
+При временных ошибках — до 6 попыток с увеличением задержки и учётом `Retry-After`; зависшая отправка получает
+новую аренду через 60 секунд. Потеря процесса между принятием сообщения MAX и записью успеха в БД может
+привести к повторному сообщению: MAX не предоставляет ключ идемпотентности отправки.
+Не удалять строки дедупликации/очереди без согласованной политики хранения. При большом количестве пациентов
+нужны пакетное сканирование завершённых тестов и общий ограничитель скорости; текущая реализация рассчитана на MVP.
+
+Проверки разработчика: `make lint test`; тесты MAX работают с синтетикой и подменённым HTTP-транспортом.
+Реальную доставку подтвердит только пробное подключение после выдачи токена и настройки публичного сервера.
