+# Текущий контекст проекта
+
+## Статус: Базовая интеграция с TDLib работает
+
+### Что сделано
+
+#### TDLib интеграция
+- Подключена библиотека `tdlib-rs` v1.1 с автоматической загрузкой TDLib
+- Реализована авторизация через телефон + код + 2FA пароль
+- Сессия сохраняется автоматически в папке `tdlib_data/`
+- Отключены логи TDLib через FFI вызов `td_execute` до создания клиента
+- Updates обрабатываются в отдельном потоке через `mpsc` канал (неблокирующе)
+
+#### Функциональность
+- Загрузка списка чатов (до 50 штук)
+- Отображение названия чата и счётчика непрочитанных
+- Загрузка истории сообщений при открытии чата
+- Отображение сообщений с именем отправителя и временем
+
+#### Управление
+- `j/k` или стрелки — навигация по списку чатов
+- `д/л` — русская раскладка для j/k
+- `Enter` — открыть выбранный чат
+- `Esc` — закрыть открытый чат
+- `Ctrl+k` — перейти к первому чату
+- `Ctrl+R` — обновить список чатов
+- `Ctrl+C` — выход
+
+### Структура проекта
+
+```
+src/
+├── main.rs           # Точка входа, UI рендеринг, event loop
+├── tdlib/
+│   ├── mod.rs        # Модуль экспорта
+│   └── client.rs     # TdClient: авторизация, загрузка чатов, сообщений
+```
+
+### Ключевые решения
+
+1. **Неблокирующий receive**: TDLib updates приходят в отдельном потоке и передаются в main loop через `mpsc::channel`. Это позволяет UI оставаться отзывчивым.
+
+2. **FFI для логов**: Используем прямой вызов `td_execute` для отключения логов синхронно, до создания клиента, чтобы избежать вывода в терминал.
+
+3. **Синхронизация чатов**: Чаты загружаются асинхронно через updates. Main loop периодически синхронизирует `app.chats` с `td_client.chats`.
+
+### Зависимости (Cargo.toml)
+
+```toml
+ratatui = "0.29"
+crossterm = "0.28"
+tdlib-rs = { version = "1.1", features = ["download-tdlib"] }
+tokio = { version = "1", features = ["full"] }
+serde = { version = "1.0", features = ["derive"] }
+serde_json = "1.0"
+dotenvy = "0.15"
+```
+
+### Переменные окружения (.env)
+
+```
+API_ID=your_api_id
+API_HASH=your_api_hash
+```
+
+## Что НЕ сделано / TODO
+
+- [ ] Отправка сообщений
+- [ ] Поиск по чатам
+- [ ] Папки телеграма (сейчас только "All")
+- [ ] Отображение онлайн-статуса пользователя
+- [ ] Markdown форматирование в сообщениях
+- [ ] Скролл истории сообщений
+- [ ] Отметка сообщений как прочитанные
+- [ ] Обновление чатов в реальном времени (новые сообщения)
+
+## Известные проблемы
+
+1. При первом запуске нужно пройти авторизацию
+2. Имя отправителя показывается как "User_ID" (нужно загружать имена пользователей)

+# Правила локальной разработки
+
+> **Обязательно к прочтению перед началом работы!**
+
+---
+
+## Инструменты
+
+### MCP серверы
+- **Serena** — для работы с кодом (символьная навигация, редактирование)
+- **Context7** — для получения актуальной документации по библиотекам
+
+Используй эти инструменты для эффективной работы с кодовой базой.
+
+---
+
+## Правила работы
+
+### 1. Никогда не запускай сервисы самостоятельно
+
+**ЗАПРЕЩЕНО** запускать `cargo run`, `cargo build` и подобные команды.
+
+**Вместо этого попроси пользователя запустить:**
+
+```
+Запусти, пожалуйста:
+cargo run
+```
+
+### 2. Тестирование — только ручное
+
+После завершения задачи:
+1. Опиши сценарии для проверки
+2. Попроси пользователя проверить вручную
+3. Дождись фидбека
+
+**Формат:**
+```
+Готово! Проверь, пожалуйста:
+
+1. Открой cargo run
+2. понавигируйся в списке чатов кнопками h j k l
+3. Нажми Enter для открытия чата
+4. Убедись, что чат прогурзился
+
+Напиши, если что-то не работает.
+```
+
+### 3. Работа поэтапно
+
+Делай работу **небольшими итерациями**:
+
+1. **Один этап = одна логическая единица**
+   - Один endpoint
+   - Один компонент
+   - Одна фича
+
+2. **После каждого этапа:**
+   - Сообщи что сделано
+   - Дай сценарий проверки
+   - Дождись подтверждения
+
+3. **Не делай сразу много:**
+   - ❌ Весь CRUD за раз
+   - ✅ Сначала GET, проверили, потом POST, проверили...
+
+---
+
+## Чеклист перед началом работы
+
+- [ ] Прочитал CONTEXT.md
+- [ ] Прочитал ROADMAP.md (понял текущую фазу)
+- [ ] Понял задачу
+- [ ] Готов работать поэтапно
+- [ ] Помню: не запускаю сервисы сам, прошу пользователя
+
+---
+
+## Пример правильного workflow
+
+```
+Пользователь: Сделай endpoint для получения списка идей
+
+Агент:
+1. Читает документацию через Context7 (NestJS, TypeORM)
+2. Использует Serena для навигации по коду
+3. Создаёт endpoint GET /api/ideas
+4. Сообщает:
+
+   "Создал endpoint GET /api/ideas.
+
+   Запусти backend:
+   cd backend && npm run dev
+
+   Проверь:
+   curl http://localhost:4001/api/ideas
+
+   Должен вернуться пустой массив: { data: [], meta: {...} }"
+
+5. Ждёт фидбек
+6. Переходит к следующему этапу

+  **commands**
+
+
+### Список желаемого
+1) футер - список папок в телеграме
+2) список с чатами - лички и группы, сверху инпут для поиска чата
+3) основной контент - открытый чат с сообщениями из чата, если никакой чат не открыт, то контент пустой, ничего не показываем. Снизу - инпут для ввода сообщения в чат, который открыт
+4) снизу списка чата статус онлайн или нет сам пользователь приложения
+5) при открытии чата должна загружаться история чата, а так же подгружаться новые сообщения от собеседника.
+6) выделяем сообщения собеседника его никнеймом, группируем его сообщения и разделяем наши сообщения и сообщения собеседника, как на интерфейсе сверху
+7) отображаем наше сообщение символом `✓`, если телеграм подтвердил, что сообщение отправлено, и выделяем `✓✓` если собеседник прочитал его
+8) при навигации в чате выделяем строку курсивом, при выборе чата (то есть его открытии) ставим в начало символ ▌
+9) `(2)` — счетчик непрочитанных (можно красить в красный/зеленый).
+10) `muted` — статус чата (серый цвет).
+11) `@` — пинг/меншн.
+12) с видео/картинками/голосовые пока ничего не делаем, ренденим заглушку (с упоминанием что это картинка или видео и тд)
+
+### Управление
+1) ctrl+c или command+c - выход из программы
+2) "h j k l" - влево, вниз, вверх, вправо (навигация в левом столбце) vim-style управление
+3) стрелки - управление, так же как и "h j k l"
+4) "command + 1", "command + 2" и так далее - переключение между папками, которые созданы в телеграме
+5) из интерфейса "**message**" - это инпут для ввода сообщения в открытый чат
+6) ctrl + s - фокус в инпут поиска чата
+7) Esc - закрытие открытого чата
+8) command + стрелка вверх (или ctrl + k) - выделяем самый верхний чат (без открытия)
+9) поддержка русской раскладки: "р о л д" соответствует "h j k l"
+10) Ctrl+R - обновить список чатов
+
+### Реализованные команды (footer)
+
+```
+j/k: Navigate | Ctrl+k: First | Enter: Open | Esc: Close | Ctrl+R: Refresh | Ctrl+C: Quit
+```
+
+## Технологии
+Пишем на rust-е
+
+1) ratatui - для tui интерфейса
+2) tdlib-rs - для подключения апи телеграма (обёртка над TDLib)
+3) tokio - async runtime
+4) crossterm - кроссплатформенный терминал
+
+## Нефункциональные требования
+
+### Производительность
+1) программа должна выдавать 60 фпс

+# Интеграция TDLib в Telegram TUI
+
+## Обзор
+
+TDLib (Telegram Database Library) — это официальная кроссплатформенная библиотека для создания Telegram клиентов. Она предоставляет полный функционал Telegram API с автоматическим управлением сессиями, кэшированием и синхронизацией.
+
+## Выбор библиотеки для Rust
+
+Существует несколько Rust-оберток для TDLib:
+
+### 1. rust-tdlib
+- **GitHub**: [antonio-antuan/rust-tdlib](https://github.com/antonio-antuan/rust-tdlib)
+- **docs.rs**: https://docs.rs/rust-tdlib
+- **Особенности**:
+  - Async/await с tokio
+  - Client/Worker архитектура
+  - Требует предварительной сборки TDLib
+
+### 2. tdlib-rs (Рекомендуется)
+- **GitHub**: [FedericoBruzzone/tdlib-rs](https://github.com/FedericoBruzzone/tdlib-rs)
+- **crates.io**: https://crates.io/crates/tdlib-rs
+- **docs.rs**: https://docs.rs/tdlib/latest/tdlib/
+- **Преимущества**:
+  - ✅ Не требует предварительной установки TDLib
+  - ✅ Кроссплатформенность (Windows, Linux, macOS)
+  - ✅ Автоматическая загрузка прекомпилированных бинарников
+  - ✅ Поддержка TDLib v1.8.29
+  - ✅ Автогенерация типов из TL схемы
+
+## Установка tdlib-rs
+
+### Вариант 1: Автоматическая загрузка (Рекомендуется)
+
+**Cargo.toml:**
+```toml
+[dependencies]
+tdlib-rs = { version = "0.3", features = ["download-tdlib"] }
+tokio = { version = "1", features = ["full"] }
+
+[build-dependencies]
+tdlib-rs = { version = "0.3", features = ["download-tdlib"] }
+```
+
+**build.rs:**
+```rust
+fn main() {
+    tdlib_rs::build::build(None);
+}
+```
+
+### Вариант 2: Локальная установка TDLib
+
+Если TDLib уже установлен (версия 1.8.29):
+
+```bash
+export LOCAL_TDLIB_PATH=$HOME/lib/tdlib
+```
+
+```toml
+[dependencies]
+tdlib-rs = { version = "0.3", features = ["local-tdlib"] }
+```
+
+### Вариант 3: Через pkg-config
+
+```bash
+export PKG_CONFIG_PATH=$HOME/lib/tdlib/lib/pkgconfig/:$PKG_CONFIG_PATH
+export LD_LIBRARY_PATH=$HOME/lib/tdlib/lib/:$LD_LIBRARY_PATH
+```
+
+```toml
+[dependencies]
+tdlib-rs = { version = "0.3", features = ["pkg-config"] }
+```
+
+## Архитектура TDLib
+
+### Основные компоненты
+
+```

+```
+
+### Поток работы
+
+1. **Инициализация** → TDLib запускается с параметрами
+2. **Авторизация** → Проход через стейт-машину авторизации
+3. **Синхронизация** → Загрузка базовых данных (чаты, контакты)
+4. **Updates Stream** → Постоянный поток обновлений от сервера
+5. **API Requests** → Запросы на получение данных / отправку сообщений
+
+## Процесс авторизации
+
+### Стейт-машина авторизации
+
+TDLib работает через систему состояний. Приложение получает обновления `updateAuthorizationState` и реагирует на них:
+
+```
+authorizationStateWaitTdlibParameters
+    ↓ (вызываем setTdlibParameters)
+authorizationStateWaitPhoneNumber
+    ↓ (вызываем setAuthenticationPhoneNumber)
+authorizationStateWaitCode
+    ↓ (вызываем checkAuthenticationCode)
+authorizationStateWaitPassword (опционально, если 2FA)
+    ↓ (вызываем checkAuthenticationPassword)
+authorizationStateReady ✓
+```
+
+### Шаг 1: Получение API ключей
+
+Перед началом работы нужно:
+1. Зайти на https://my.telegram.org
+2. Войти с номером телефона
+3. Перейти в "API development tools"
+4. Создать приложение и получить `api_id` и `api_hash`
+
+### Шаг 2: Инициализация TDLib
+
+```rust
+use tdlib::{functions, types};
+
+async fn init_tdlib() {
+    // Параметры инициализации
+    let params = types::TdlibParameters {
+        database_directory: "./tdlib_db".to_string(),
+        use_message_database: true,
+        use_secret_chats: true,
+        api_id: env::var("API_ID").unwrap().parse().unwrap(),
+        api_hash: env::var("API_HASH").unwrap(),
+        system_language_code: "en".to_string(),
+        device_model: "Desktop".to_string(),
+        system_version: "Unknown".to_string(),
+        application_version: "0.1.0".to_string(),
+        enable_storage_optimizer: true,
+        ignore_file_names: false,
+    };
+
+    // Отправляем параметры
+    functions::set_tdlib_parameters(params, &client).await?;
+}
+```
+
+### Шаг 3: Ввод номера телефона
+
+```rust
+async fn authenticate_with_phone(phone: String, client: &Client) {
+    let phone_number = types::SetAuthenticationPhoneNumber {
+        phone_number: phone,
+        settings: None,
+    };
+
+    functions::set_authentication_phone_number(phone_number, client).await?;
+}
+```
+
+### Шаг 4: Ввод кода подтверждения
+
+```rust
+async fn verify_code(code: String, client: &Client) {
+    let check_code = types::CheckAuthenticationCode {
+        code,
+    };
+
+    functions::check_authentication_code(check_code, client).await?;
+}
+```
+
+### Шаг 5: Ввод пароля 2FA (если включен)
+
+```rust
+async fn verify_password(password: String, client: &Client) {
+    let check_password = types::CheckAuthenticationPassword {
+        password,
+    };
+
+    functions::check_authentication_password(check_password, client).await?;
+}
+```
+
+## Получение списка чатов
+
+### Концепция чатов в TDLib
+
+TDLib автоматически кэширует чаты локально. Приложение должно:
+1. Подписаться на обновления `updateNewChat`
+2. Вызвать `loadChats()` для загрузки чатов
+3. Поддерживать локальный кэш с сортировкой
+
+### Типы списков чатов
+
+- **Main** — основные чаты
+- **Archive** — архивные чаты
+- **Folder** — пользовательские папки
+
+### Загрузка чатов
+
+```rust
+use tdlib::{functions, types};
+
+async fn load_chats(client: &Client) -> Result<Vec<Chat>> {
+    // Указываем тип списка (Main, Archive, или конкретная папка)
+    let chat_list = types::ChatList::Main;
+
+    // Загружаем чаты
+    // limit - количество чатов для загрузки
+    functions::load_chats(
+        types::LoadChats {
+            chat_list: Some(chat_list),
+            limit: 50,
+        },
+        client
+    ).await?;
+
+    // После вызова loadChats, чаты будут приходить через updateNewChat
+    Ok(vec![])
+}
+```
+
+### Получение информации о чате
+
+```rust
+async fn get_chat_info(chat_id: i64, client: &Client) -> Result<types::Chat> {
+    let chat = functions::get_chat(
+        types::GetChat { chat_id },
+        client
+    ).await?;
+
+    Ok(chat)
+}
+```
+
+### Сортировка чатов
+
+Чаты нужно сортировать по паре `(position.order, chat.id)` в порядке убывания:
+
+```rust
+chats.sort_by(|a, b| {
+    let order_a = a.positions.get(0).map(|p| p.order).unwrap_or(0);
+    let order_b = b.positions.get(0).map(|p| p.order).unwrap_or(0);
+
+    order_b.cmp(&order_a)
+        .then_with(|| b.id.cmp(&a.id))
+});
+```
+
+## Получение истории сообщений
+
+### Загрузка сообщений из чата
+
+```rust
+async fn get_chat_history(
+    chat_id: i64,
+    from_message_id: i64,
+    limit: i32,
+    client: &Client
+) -> Result<Vec<types::Message>> {
+    let history = functions::get_chat_history(
+        types::GetChatHistory {
+            chat_id,
+            from_message_id, // 0 для последних сообщений
+            offset: 0,
+            limit,
+            only_local: false,
+        },
+        client
+    ).await?;
+
+    Ok(history.messages.unwrap_or_default())
+}
+```
+
+### Пагинация сообщений
+
+Сообщения возвращаются в обратном хронологическом порядке (новые → старые).
+
+Для загрузки следующей страницы:
+```rust
+// Первая загрузка (последние сообщения)
+let messages = get_chat_history(chat_id, 0, 50, &client).await?;
+
+// Загрузка более старых сообщений
+if let Some(oldest_msg) = messages.last() {
+    let older_messages = get_chat_history(
+        chat_id,
+        oldest_msg.id,
+        50,
+        &client
+    ).await?;
+}
+```
+
+## Обработка обновлений (Updates Stream)
+
+### Типы обновлений
+
+TDLib отправляет обновления через `Update` enum:
+
+- `UpdateNewMessage` — новое сообщение
+- `UpdateMessageContent` — изменение контента сообщения
+- `UpdateMessageSendSucceeded` — сообщение успешно отправлено
+- `UpdateMessageSendFailed` — ошибка отправки
+- `UpdateChatLastMessage` — изменилось последнее сообщение чата
+- `UpdateChatPosition` — изменилась позиция чата в списке
+- `UpdateNewChat` — новый чат добавлен
+- `UpdateUser` — обновилась информация о пользователе
+- `UpdateUserStatus` — изменился статус пользователя (онлайн/оффлайн)
+- `UpdateChatReadInbox` — прочитаны входящие сообщения
+- `UpdateChatReadOutbox` — прочитаны исходящие сообщения
+
+### Слушатель обновлений
+
+```rust
+use tdlib::types::Update;
+
+async fn handle_updates(client: Client) {
+    loop {
+        match client.receive() {
+            Some(Update::NewMessage(update)) => {
+                println!("New message in chat {}: {}",
+                    update.message.chat_id,
+                    update.message.content
+                );
+            }
+            Some(Update::MessageSendSucceeded(update)) => {
+                println!("Message sent successfully: {}", update.message.id);
+            }
+            Some(Update::UserStatus(update)) => {
+                println!("User {} is now {:?}",
+                    update.user_id,
+                    update.status
+                );
+            }
+            Some(Update::NewChat(update)) => {
+                println!("New chat added: {}", update.chat.title);
+            }
+            _ => {}
+        }
+    }
+}
+```
+
+## Отправка сообщений
+
+### Отправка текстового сообщения
+
+```rust
+async fn send_message(
+    chat_id: i64,
+    text: String,
+    client: &Client
+) -> Result<types::Message> {
+    let input_content = types::InputMessageContent::InputMessageText(
+        types::InputMessageText {
+            text: types::FormattedText {
+                text,
+                entities: vec![],
+            },
+            disable_web_page_preview: false,
+            clear_draft: true,
+        }
+    );
+
+    let message = functions::send_message(
+        types::SendMessage {
+            chat_id,
+            message_thread_id: 0,
+            reply_to: None,
+            options: None,
+            reply_markup: None,
+            input_message_content: input_content,
+        },
+        client
+    ).await?;
+
+    Ok(message)
+}
+```
+
+### Статусы доставки и прочтения
+
+Для отображения ✓ и ✓✓:
+
+```rust
+fn get_message_status(message: &types::Message) -> &str {
+    if message.is_outgoing {
+        match &message.sending_state {
+            Some(types::MessageSendingState::Pending) => "",  // отправляется
+            Some(types::MessageSendingState::Failed(_)) => "✗",  // ошибка
+            None => {
+                // Отправлено успешно
+                if message.chat_id > 0 {  // личный чат
+                    // Проверяем, прочитано ли
+                    // (нужно следить за UpdateChatReadOutbox)
+                    "✓✓"  // или "✓" если не прочитано
+                } else {
+                    "✓"  // групповой чат
+                }
+            }
+        }
+    } else {
+        ""  // входящее сообщение
+    }
+}
+```
+
+## Работа с папками (Folders)
+
+### Получение списка папок
+
+```rust
+async fn get_chat_folders(client: &Client) -> Result<Vec<types::ChatFolderInfo>> {
+    let folders = functions::get_chat_folders(
+        types::GetChatFolders {},
+        client
+    ).await?;
+
+    Ok(folders.chat_folders)
+}

+
+### Фильтрация чатов по папке
+
+```rust
+async fn get_chats_in_folder(folder_id: i32, client: &Client) {
+    let chat_list = types::ChatList::Folder {
+        chat_folder_id: folder_id

+### Разделение ответственности
+
+1. **TDLib Client** — управление клиентом, запросы к API
+2. **Update Handler** — обработка обновлений в фоне
+3. **App State** — состояние приложения (чаты, сообщения, UI)
+4. **UI Layer** — отрисовка интерфейса (ratatui)
+
+### Коммуникация между слоями
+
+```rust
+// Используем каналы для коммуникации
+use tokio::sync::mpsc;
+
+#[derive(Debug)]
+enum AppEvent {
+    NewMessage(Message),
+    ChatUpdated(Chat),
+    UserStatusChanged(i64, UserStatus),
+}
+
+#[tokio::main]
+async fn main() {
+    // Канал для событий от TDLib
+    let (tx, mut rx) = mpsc::channel::<AppEvent>(100);
+
+    // Запускаем TDLib в отдельной задаче
+    tokio::spawn(async move {
+        run_tdlib_client(tx).await;
+    });
+
+    // Основной UI loop
+    loop {
+        // Проверяем события
+        while let Ok(event) = rx.try_recv() {
+            match event {
+                AppEvent::NewMessage(msg) => {
+                    // Обновляем UI
+                }
+                _ => {}
+            }
+        }
+
+        // Отрисовываем UI
+        terminal.draw(|f| ui(f, &app))?;
+
+        // Обрабатываем ввод пользователя
+        handle_input()?;

+```
+
+## Пример: Минимальный клиент
+
+```rust

+        client.start().await;
+    });
+
+    // 3. Ждем авторизации

+    }
+
+    // 4. Загружаем чаты

+            handle_update(update);
+        }

+
+    Ok(())

+
+## Best Practices
+
+### 1. Кэширование
+- Всегда включай `use_message_database: true`
+- Храни кэш чатов и сообщений в памяти
+- Используй `only_local: true` для быстрого доступа
+
+### 2. Обработка ошибок
+- Все TDLib функции возвращают `Result`
+- Обрабатывай потерю соединения
+- Переподключайся при ошибках сети
+
+### 3. Производительность
+- Не загружай все чаты сразу (используй пагинацию)
+- Лимитируй количество сообщений в истории
+- Используй `offset` для ленивой загрузки
+
+### 4. UI/UX
+- Показывай индикаторы загрузки
+- Кэшируй отрисованные элементы
+- Обновляй UI только при изменениях
+
