-# Соединение с сервером и сессии
-
-## 1) Базовый транспорт
-
-- Сервер работает по WebSocket + JSON-протокол (`op`, `requestId`, `payload`).
-- Для каждой операции есть handler в `JsonHandlerRegistry`.
-
-## 2) Схема авторизации (актуальная)
-
-В проекте реализованы **две двухшаговые схемы**:
-
-### A. Создание новой сессии (через device key)
-
-1. `AuthChallenge(login)`
-   - сервер проверяет, что пользователь существует;
-   - кладёт в контекст соединения `authNonce`.
-
-2. `CreateAuthSession(...)`
-   - клиент подписывает строку `AUTH_CREATE_SESSION:{login}:{timeMs}:{authNonce}` приватным **device key**;
-   - сервер валидирует подпись, создаёт запись в `active_sessions`, возвращает `sessionId`;
-   - в сессии хранится `session_key` (публичный ключ сессии), который клиент сгенерировал для дальнейших логинов.
-
-### B. Вход в существующую сессию (через session key)
-
-1. `SessionChallenge(sessionId)`
-   - сервер выдаёт одноразовый nonce с TTL.
-
-2. `SessionLogin(sessionId, timeMs, signature)`
-   - клиент подписывает `SESSION_LOGIN:{sessionId}:{timeMs}:{nonce}` приватным ключом сессии;
-   - сервер проверяет подпись по `active_sessions.session_key`;
-   - при успехе возвращает `storagePwd`.
-
-## 3) Работа со списком сессий
-
-### `ListSessions`
-
-- Доступно только в состоянии `AUTH_STATUS_USER`.
-- Возвращает все активные сессии текущего пользователя:
-  - `sessionId`
-  - информация о клиенте
-  - `lastAuthirificatedAtMs`
-  - гео (по ip, через кэш/lookup).
-
-### `CloseActiveSession`
-
-- В реестре операций присутствует.
-- Используется для закрытия указанной или текущей сессии.
-
-## 4) Важные детали безопасности
-
-- Есть проверка рассинхрона времени клиента (обычно ±30 секунд).
-- Nonce одноразовые, хранятся в контексте конкретного ws-соединения.
-- При ошибках подписи/контекста сервер может закрывать WebSocket.
-
-## 5) Что уже хорошо
-
-- Разделены key-и: `device key` (создание сессии) и `session key` (повторные входы).
-- Не передаётся приватный ключ — только подписи.
-- Авторизация привязана к challenge/nonce.
-
-## 6) Что стоит дополнительно улучшить
-
-1. Добавить централизованный лимит попыток на `SessionLogin`/`CreateAuthSession`.
-2. Логировать причины отказов в метриках (без утечки чувствительных данных).
-3. Явно документировать формат Base64 (URL-safe/standard) для каждого поля, чтобы клиенты не путались.

-# Структура блокчейна и типы блоков
-
-## 1) Общая модель
-
-Каждый блок содержит:
-
-- заголовок (тип, subtype, version, blockNumber и пр.);
-- `bodyBytes` (полезная нагрузка конкретного типа);
-- хэш и подпись.
-
-На сервере при `AddBlock` выполняется:
-
-1. Проверка формата блока.
-2. `body.check()`.
-3. Проверка непрерывности цепочки (`blockNumber == last + 1`, `prevHash`).
-4. Проверка подписи блока ключом блокчейна.
-5. Сохранение в БД + файл блокчейна.
-
-## 2) Типы блоков (msg_type)
-
-## type=0 (TECH / HEADER)
-
-- `HEADER_COMPAT (subType=0)` — стартовый служебный блок.
-- `TECH_CREATE_CHANNEL (subType=1)` — создание канала (линии) с именем канала.
-
-Что можно делать:
-- инициализировать blockchain;
-- заводить новые каналы внутри blockchain.
-
-## type=1 (TEXT)
-
-- `TEXT_POST (10)` — публикация в линии канала.
-- `TEXT_EDIT_POST (11)` — редактирование поста (target на оригинал).
-- `TEXT_REPLY (20)` — reply на любой target (может быть чужой блокчейн).
-- `TEXT_EDIT_REPLY (21)` — редактирование reply.
-
-Что можно делать:
-- публиковать посты в каналы;
-- делать древовидные ответы;
-- редактировать ранее отправленные тексты.
-
-## type=2 (REACTION)
-
-- `REACTION_LIKE (1)` — лайк на target-блок.
-
-Что можно делать:
-- ставить лайки на сообщение.
-
-## type=3 (CONNECTION)
-
-- `FRIEND / UNFRIEND`
-- `CONTACT / UNCONTACT`
-- `FOLLOW / UNFOLLOW`
-
-Что можно делать:
-- дружба, контакты, подписки.
-
-## type=4 (USER_PARAM)
-
-- `USER_PARAM_TEXT_TEXT (1)` — произвольный `key/value` параметр пользователя.
-
-Что можно делать:
-- хранить пользовательские технические настройки и состояние синхронизации.
-
-## 3) Линии (line model)
-
-Для части блоков есть line-поля:
-- `line_code`
-- `prev_line_number`
-- `prev_line_hash`
-- `this_line_number`
-
-Смысл:
-- отдельные последовательности для каналов/связей/параметров;
-- БД-триггеры проверяют целостность ссылок line->prev.
-
-## 4) Target model
-
-Для reply/like/connection/edit используются target-поля:
-- `to_bch_name`
-- `to_block_number`
-- `to_block_hash`
-- `to_login` (сервер может вычислять из blockchainName).
-
-Это позволяет строить граф:
-- кто на кого подписался;
-- кто кому ответил;
-- кто какой блок лайкнул;
-- какой блок является edit какого.
-
-## 5) Сильные стороны текущей структуры
-
-- Достаточно выразительная модель для соц-сценариев (каналы/ответы/лайки/связи).
-- Есть счетчики `message_stats` (likes/replies/edits) на уровне БД.
-- Есть `connections_state` как «текущее состояние», собранное триггерами.
-
-## 6) Статус унификации subType
-
-Схема `subType` должна быть единой во всех модулях проекта:
-
-- `TEXT_POST = 10`
-- `TEXT_EDIT_POST = 11`
-- `TEXT_REPLY = 20`
-- `TEXT_EDIT_REPLY = 21`
-
-Это правило должно одинаково использоваться в `shine-server-blockchain`, `shine-server-db`, SQL-триггерах и DAO.

-# Какие блоки можно добавлять и что уже есть по API
-
-## 1) Что реально доступно по сети сейчас
-
-В `JsonHandlerRegistry` сейчас есть:
-- `AddBlock`
-- `GetFriendsLists`
-- `UpsertUserParam`, `GetUserParam`, `ListUserParams`
-- auth/system и тестовые операции.
-
-Отдельных read-API для каналов/сообщений пока нет (только запись блока + частично списки друзей + user params).
-
-## 2) Как добавляются блоки
-
-Через `AddBlock` клиент отправляет:
-- blockchainName
-- blockNumber
-- prevBlockHash
-- blockBytesB64
-
-Сервер:
-- парсит block;
-- проверяет подпись блокчейна;
-- извлекает `line`/`target` из body;
-- сохраняет в `blocks`;
-- обновляет `blockchain_state`;
-- триггеры автоматически обновляют производные таблицы (`connections_state`, `message_stats`).
-
-## 3) Конкретные сценарии
-
-### 3.1 Создать канал
-
-Добавить TECH-блок `CreateChannelBody` (type=0/subType=TECH_CREATE_CHANNEL).
-
-### 3.2 Опубликовать сообщение в своём канале
-
-Добавить `TEXT_POST` в нужную линию канала (`lineCode` указывает на root канала).
-
-### 3.3 Ответ на сообщение
-
-Добавить `TEXT_REPLY` с target (`toBlockchainName`, `toBlockGlobalNumber`, `toBlockHash32`).
-
-### 3.4 Лайк
-
-Добавить `REACTION_LIKE` с target сообщения.
-
-### 3.5 Подписаться / отписаться от канала
-
-Добавить `CONNECTION_FOLLOW` / `CONNECTION_UNFOLLOW` с target root канала.
-
-### 3.6 Добавить в контакты/друзья
-
-- Контакты: `CONNECTION_CONTACT` / `CONNECTION_UNCONTACT`.
-- Друзья: `CONNECTION_FRIEND` / `CONNECTION_UNFRIEND`.
-
-## 4) Есть ли метод «подписаться на канал» кроме публикации?
-
-Да: подписка — это **не отдельный RPC**, а блок `CONNECTION_FOLLOW`, отправляемый через `AddBlock`.
-
-## 5) Есть ли методы для сохранения технического состояния (например, сколько прочитано)
-
-Да, есть `UpsertUserParam`.
-
-Практично хранить:
-- `channel_last_read:<bchName>:<lineCode> -> <lastSeenMessageSeq или blockNumber>`
-- `channel_last_sync_at -> <time_ms>`
-
-Ограничение: `users_params` сейчас хранит строки `param/value`, то есть сложные структуры лучше класть в JSON-строку с версией схемы.
-
-## 6) Чего не хватает прямо сейчас
-
-1. Нет RPC, который вернёт **список подписанных каналов** и счётчики сообщений.
-2. Нет RPC, который вернёт **сообщения конкретного канала** (с пагинацией).
-3. Нет RPC, который вернёт **подробный тред сообщения** (предки + все ответы) одним JSON.
-4. Нет RPC «ленты событий» (кто лайкнул/ответил/подписался) как отдельного серверного канала.

-# Проектирование запросов: подписки, счетчики, синхронизация, сообщения
-
-## 1) Цель
-
-Сделать один запрос, который отдаёт:
-- все каналы пользователя (подписки + опционально self-каналы);
-- сколько сообщений всего в каждом канале;
-- сколько новых (с учётом last_read).
-
-И отдельно:
-- запрос сообщений канала;
-- запрос треда конкретного сообщения (предки + все потомки + stats).
-
-## 2) Предлагаемые API
-
-## A. `ListMyChannelsWithCounters`
-
-### Request
-```json
-{
-  "op": "ListMyChannelsWithCounters",
-  "requestId": "...",
-  "includeSelf": true,
-  "includePrivate": true
-}
-```
-
-### Response
-```json
-{
-  "op": "ListMyChannelsWithCounters",
-  "requestId": "...",
-  "status": 200,
-  "channels": [
-    {
-      "channelId": "targetBch:targetRootBlock",
-      "channelType": "personal|public|system_notifications|dm",
-      "ownerLogin": "Alice",
-      "bchName": "Alice-001",
-      "lineCode": 0,
-      "title": "Alice main",
-      "totalMessages": 1234,
-      "lastReadSeq": 1200,
-      "newMessages": 34,
-      "lastMessage": {
-        "blockNumber": 3500,
-        "timeMs": 1760000000000,
-        "preview": "..."
-      }
-    }
-  ]
-}
-```
-
-## B. `GetChannelMessages`
-
-- Возвращает сообщения канала по `channelId` или `(bchName,lineCode)`.
-- Нужны `limit`, `before/after`, сортировка и флаг `includeStats`.
-
-## C. `GetMessageThreadGraph`
-
-Один JSON для:
-- целевого сообщения;
-- всей цепочки родителей до корня;
-- всех ответов (даже 100+);
-- stats по каждому узлу (`likes/replies/edits`).
-
-## 3) Как считать total/new
-
-## Источник truth по подпискам
-
-Использовать `connections_state` где `rel_type=FOLLOW`.
-
-## Источник сообщений канала
-
-`blocks` где `msg_type=TEXT` и блок принадлежит линии канала (`line_code`).
-
-## Источник last_read
-
-`users_params` ключ вида `read.<channelId>` = число (last seen seq или blockNumber).
-
-`newMessages = max(0, totalMessages - lastReadSeq)` (или по blockNumber/seq в выбранной модели).
-
-## 4) Offline/online синхронизация
-
-Рекомендуемый поток:
-
-1. Клиент локально хранит last_read/last_sync.
-2. При подключении делает:
-   - `ListMyChannelsWithCounters`
-   - затем по каналам с `newMessages > 0` делает `GetChannelMessages`.
-3. После отображения сообщений обновляет сервер через `UpsertUserParam` (или новый bulk-метод).
-4. Сервер всегда остаётся source of truth для chain/подписок; клиент — кэш.
-
-## 5) Подписи и device key
-
-- Операции изменения данных пользователя (`UpsertUserParam`) уже подписываются device key.
-- Для нового bulk-обновления read-состояния лучше сохранить тот же принцип: подписанный payload от device key.
-
-## 6) Разделение каналов: личные / обычные / системные
-
-Предложение:
-
-- `personal_main`: root = HEADER (`lineCode=0`) пользователя.
-- `public_channel`: root = CREATE_CHANNEL (lineCode = blockNumber root).
-- `dm_channel`: отдельный тип канала (пока не реализован; либо как специальный connection+line policy).
-- `system_notifications`: виртуальный/материализованный канал событий (ответы, лайки, follow/unfollow/friend/contact).
-
-## 7) Канал уведомлений (ответили/лайкнули/подписались)
-
-Сейчас это не готово как отдельная сущность API.
-
-Два варианта:
-
-1. **Виртуальный канал (рекомендуется сначала)**
-   - не писать новые блоки;
-   - собирать события SQL-запросом из `blocks` + `message_stats` + `connections_state`.
-
-2. **Материализованный канал**
-   - триггеры/воркер пишут отдельные event-записи в таблицу уведомлений;
-   - быстрее чтение, но сложнее консистентность.
-
-## 8) Что уже частично готово
-
-- База уже считает `likes/replies/edits` через `message_stats` триггеры.
-- База уже держит текущее состояние связей через `connections_state`.
-
-## 9) Что нужно дописать в сервере
-
-1. Новые handlers в `JsonHandlerRegistry`:
-   - `ListMyChannelsWithCounters`
-   - `GetChannelMessages`
-   - `GetMessageThreadGraph`
-   - `ListNotificationFeed`.
-2. Новые DAO + SQL-представления/CTE.
-3. Унификация subType-констант (иначе статистика и выборки будут «плыть»).
-4. Пагинация и лимиты ответа (для больших тредов).

-# Открытые вопросы и TODO для согласования
-
-## Критичные вопросы
-
-1. **Что считаем “сообщением канала” для counters**
-   - Только `TEXT_POST`?
-   - Или ещё `TEXT_EDIT_POST` и/или `REPLY` в этом же line?
-
-2. **Что такое “прочитано”**
-   - По `this_line_number`?
-   - По `block_number`?
-   - По времени?
-
-3. **Личные и публичные каналы**
-   - Явно вводим `channelType` в API?
-   - Нужны ли отдельные private/dm каналы в MVP?
-
-4. **Уведомления (лайк/reply/follow/friend)**
-   - Делаем сначала виртуальный канал (query-time), потом материализацию?
-
-## Технический TODO (рекомендуемый порядок)
-
-1. Добавить DAO для выборки каналов с counters.
-2. Добавить read-api handlers (3-4 операции, описанные в 04 документе).
-3. Добавить integration tests:
-   - подписка -> counters;
-   - read progress -> newMessages;
-   - thread graph на 100+ ответов.
-4. Добавить индекс(ы) под новые query-паттерны (по `line_code`, `to_*`, `msg_type/subtype`).
-
-## Дополнительные идеи
-
-- Для `GetMessageThreadGraph` можно вводить режимы:
-  - `full` (все ответы)
-  - `compact` (первые N + hasMore)
-- Для клиентской синхронизации можно добавить `syncToken` (версия снимка данных), чтобы отличать повторный ответ от изменений после запроса.

+## Человеко-читаемое объяснение
+Эти 3 функции — это **чтение данных каналов** для UI:
+
+1. `ListSubscriptionsFeed` — отдает данные для экрана списка каналов:
+   - ваши каналы (личный + созданные вами),
+   - каналы пользователей, на кого вы подписаны,
+   - отдельные каналы, на которые вы подписаны напрямую.
+
+2. `GetChannelMessages` — отдает полную ленту одного канала (пока без курсоров, загружается сразу целиком),
+   включая версии сообщений, лайки и ответы.
+
+3. `GetMessageThread` — отдает дерево обсуждения вокруг конкретного сообщения:
+   предки, фокус-сообщение, потомки.
+
+> На первом этапе мы **не используем курсоры** (`nextCursor`) и загружаем полные списки.

+# 07. Channels Feature Runbook (человеческое описание + диагностика)
+
+## 1) Что уже сделано простыми словами
+
+Сейчас реализован полный минимальный контур для каналов:
+
+1. **Серверные read API**:
+   - `ListSubscriptionsFeed` — экран списка каналов.
+   - `GetChannelMessages` — сообщения конкретного канала.
+   - `GetMessageThread` — дерево обсуждения для сообщения.
+
+2. **UI вкладки Каналы**:
+   - при открытии пытается загрузить реальный feed с сервера;
+   - если сервер недоступен — fallback на мок-данные;
+   - группы каналов выводятся в нужном порядке;
+   - есть кнопка «Добавить канал», модалки подписки, переход в канал.
+
+3. **Проверка уникальности имени канала на сервере**
+   - в `AddBlock` при `CreateChannelBody` добавлена проверка;
+   - при дубле возвращается `409 channel_name_already_exists`.
+
+---
+
+## 2) Что тестировать в первую очередь (быстрый чеклист)
+
+### Базовый smoke
+1. Авторизоваться в UI.
+2. Открыть вкладку «Каналы».
+3. Убедиться, что данные загрузились с сервера (или виден fallback-баннер).
+4. Нажать любой канал — должен открыться экран канала с сообщениями.
+
+### API smoke
+1. Вызвать `ListSubscriptionsFeed`.
+2. Для канала `ownedChannels[0]` вызвать `GetChannelMessages`.
+3. Для первого `messages[0]` вызвать `GetMessageThread`.
+
+### Ошибки
+1. `ListSubscriptionsFeed` с пустым login -> `bad_fields`.
+2. `GetChannelMessages` с битым channel payload -> `bad_fields`.
+3. `GetMessageThread` с несуществующим block -> `message_not_found`.
+4. `AddBlock(CreateChannel)` с уже существующим именем -> `channel_name_already_exists`.
+
+---
+
+## 3) Готовые JSON-запросы для ручной диагностики
+
+## 3.1 ListSubscriptionsFeed
+```json
+{
+  "op": "ListSubscriptionsFeed",
+  "requestId": "debug-feed-1",
+  "payload": {
+    "login": "TestUser1",
+    "limit": 200
+  }
+}
+```
+
+## 3.2 GetChannelMessages
+```json
+{
+  "op": "GetChannelMessages",
+  "requestId": "debug-ch-1",
+  "payload": {
+    "channel": {
+      "ownerBlockchainName": "TestUser1-001",
+      "channelRootBlockNumber": 0,
+      "channelRootBlockHash": ""
+    },
+    "limit": 200,
+    "sort": "asc"
+  }
+}
+```
+
+## 3.3 GetMessageThread
+```json
+{
+  "op": "GetMessageThread",
+  "requestId": "debug-thread-1",
+  "payload": {
+    "message": {
+      "blockchainName": "TestUser1-001",
+      "blockNumber": 123,
+      "blockHash": "<hash-from-GetChannelMessages>"
+    },
+    "depthUp": 20,
+    "depthDown": 2,
+    "limitChildrenPerNode": 50
+  }
+}
+```
+
+---
+
+## 4) Что смотреть в ответах
+
+### ListSubscriptionsFeed
+- `payload.login` — канонический login.
+- `ownedChannels / followedUsersChannels / followedChannels` — массивы.
+- у каждой записи есть:
+  - `channel.channelRoot.blockNumber`,
+  - `messagesCount`,
+  - `lastMessage` (может быть null, если сообщений нет).
+
+### GetChannelMessages
+- `payload.channel` заполнен;
+- `payload.messages[]` содержит:
+  - `likesCount`, `repliesCount`,
+  - `versionsTotal`, `versions[]`,
+  - `text` должен быть текущей (последней) версией.
+
+### GetMessageThread
+- `payload.ancestors[]`, `payload.focus`, `payload.descendants[]`.
+- у узлов должны быть версии и счетчики.
+
+---
+
+## 5) Частые проблемы и как быстро локализовать
+
+1. **`status != 200`, code=bad_fields**
+   - проверить вложенность payload и обязательные поля.
+
+2. **`message_not_found` в GetMessageThread**
+   - обычно передали blockNumber/hash не из `messageRef`.
+
+3. **Пустой список сообщений в GetChannelMessages**
+   - проверить `ownerBlockchainName` и `channelRootBlockNumber`.
+
+4. **`channel_name_already_exists` при AddBlock**
+   - это ожидаемо: в этой цепочке уже есть канал с таким именем.
+
+---
+
+## 6) Для будущей доработки
+
+1. Добавить курсоры (пагинацию) для больших каналов.
+2. Перевести «Подписаться»/«Добавить канал» в UI с демо-заглушек на реальные write RPC.
+3. Добавить batch-агрегации для thread/versions (оптимизация).
+4. Добавить полноценные интеграционные тесты на негативные кейсы и нагрузку.

+## Назначение проекта
+Это демо-прототип мобильного веб-приложения в формате статического сайта.
+
+## Технические ограничения
+- Проект сделан без бэкенда, без базы данных и без реальных API.
+- Все данные моковые и хранятся в `js/mock-data.js`.
+- Навигация между экранами идет без полной перезагрузки страницы (SPA-подход на hash-router).
+
+## Обязательные требования к каждому экрану
+- У каждого экрана есть явный верхний заголовок на русском языке.
+- У каждого экрана есть нижняя служебная подпись над toolbar в формате:
+  `[Русское название] ([english-page-id])`.
+- `page-id` должен совпадать с именем JS-файла страницы или быть максимально близким к нему.
+
+## Архитектурные правила
+- Структура проекта должна оставаться понятной и модульной.
+- Новые доработки нужно вносить аккуратно, не ломая существующую навигацию.
+- Стиль проекта: темная тема, mobile-first, интерфейс на русском языке.
+
+## Экраны и файлы
+- Профиль: `js/pages/profile-view.js`
