 # API для разработчиков: уведомления
 
-Документ описывает чтение пользовательских уведомлений, которые сервер индексирует при `AddBlock`.
+Уведомления являются серверной проекцией событий блокчейна. Сервер возвращает все непросмотренные записи независимо от возраста и просмотренные записи не старше 60 дней. Пагинации нет: выдача содержит все непросмотренные и всю доступную 60-дневную просмотренную историю.
 
-Текущая операция:
+## GetNotifications
 
-- `GetNotifications`
+Авторизация обязательна. Обычно payload пустой. Legacy-поле `limit` принимается для совместимости, но в v2 игнорируется. Для обновления badge без загрузки карточек можно передать `{"countsOnly":true}`; тогда массивы лент остаются пустыми, но watermark и `*UnseenCount` возвращаются.
 
-## 1. `GetNotifications`
+Ответ содержит три ленты: `replies`, `connections`, `events`, а также `*SeenAtMs` и `*UnseenCount` для каждой категории.
 
-Метод читает уведомления текущего пользователя. В `payload.login` можно передать логин явно, но обычно клиент использует авторизованную сессию.
+- `replies`: TEXT_REPLY.
+- `connections`: friend/unfriend, close_friend/unclose_friend, shine confirmed/unconfirmed, official confirmed/unconfirmed. Контакты не создают уведомлений.
+- `events`: FOLLOW/UNFOLLOW каналов.
 
-Возвращаются две отдельные ленты:
+Фильтр каждой категории: `created_at_ms > seenAtMs OR created_at_ms >= now - 60 days`.
 
-- `replies` — ответы на сообщения пользователя в каналах и тредах;
-- `events` — события добавления в `close_friend`.
+## SetNotificationState
 
-### Запрос
+Сохраняет подписанный watermark просмотра. Сервер принимает только монотонное движение `seenAtMs` вперёд.
 
+Запрос:
 ```json
-{
-  "op": "GetNotifications",
-  "requestId": "notif-001",
-  "payload": {
-    "login": "alice",
-    "limit": 50

-### Примечание
-
-- `replies` заполняется только для `TEXT_REPLY`.
-- `events` заполняется только для входящего `CONNECTION_FRIEND` / `close_friend`.
-- Другие типы связей в эту ленту не попадают.
+Подпись `clientKey` вычисляется над всеми байтами контейнера до `signature`, по тому же принципу, что подписанный контейнер `SHiNE_DM`. Сервер проверяет, что `login` совпадает с авторизованным пользователем, проверяет Ed25519-подпись и сохраняет также исходный signed blob для будущей переносимой синхронизации состояния.
