Merge pull request #82: refactor: make session join leave platform-neutral

Convert join/leave interaction commands to PlatformUser, PlatformGroup, and PlatformMessageRef. Persist and look up participants by platform identity while keeping Telegram callbacks intact. Add V017 migration and TDD coverage. Bump version to 2.1.1.

-## ✨ Ключевые возможности
+## ✨ Key Features
 
-### 🤖 Telegram Бот
+### 🤖 Telegram Bot
-- **📅 Создание расписаний (Batch Sessions)**: Создавайте сразу несколько игр одним сообщением (на неделю или месяц вперед).
+- **📅 Создание расписаний (Batch Sessions)**: Создавайте сразу несколько игр одним сообщением изменения (на недельный месяц в перед).
-- **✋ Интерактивная запись**: Игроки записываются на конкретные даты нажатием одной кнопки.
+- **🖼 Обложки расписаний**: И batch-посту можно прикрепить фото к `/newsession` или указать строку `Картинка: https://...`; бот отправит обложку перед сообщением записи.
-- **📁 Поддержка Форумов (Telegram Topics)**: Бот автоматически создает тему во вложенных чатах Telegram под каждую новую пачку игр.
+- **⚡ Быстрые повторы расписания**: Для регулярной кампании можно указать одну дату, количество игр и интервал, а бот сам развернёт повторяющийся batch.
-- **❌ Управление сессиями**: Мастер может отменять отдельные игры прямо в общем сообщении расписания.
+- **✋ Интерактивная запись и выход**: Игроки записываются на конкретные даты и самостоятельно снимают запись нажатием одной кнопки.
-- **🗓 Экспорт в Календарь**: Генерация файла `.ics` для добавления всех игр в Google, Apple или Яндекс Календарь одной командой.
+- **👥 Лимит мест и лист ожидания**: ГМ задаёт максимальный состав, бот не переполняет сессию, автоматически ведёт очередь ожидания и освобождённое место отдаёт первому ожидающему.
-- **🚀 Native AOT**: Скомпилирован в нативный бинарный файл. Мгновенный запуск и минимальное потребление памяти. Идеально для **Raspberry Pi**.
+- **📁 Поддержка Форумов (Telegram Topics)**: Если `/newsession` запущен в теме форума Telegram, расписание и групповые уведомления остаются в этой теме; при запуске из корня форума бот создает отдельную тему и сообщает о необходимости прав admin/Manage Topics, если их не хватает.
+- **❌ Управление сессиями**: Owner и назначенные co-GM могут создавать, отменять, удалять и переносить игры из Telegram через `/listsessions`; публичный пост записи показывает только кнопки игроков.
+- **🔄 Голосование за перенос**: Быстрый поиск свободного места с через свободное недель и кнопками новых времени и дедлайном.
+- **🔔 Уведомления**: Игрок получают за 24 часа, напоминание за 1 час, ссылку перед игрой, отмены и переносы; групповые уведомления при этом остаются.
+- **🕐 Режим уведомлений batch**: Для каждой пачки можно выбрать `В группе и в личку` или `Только в группе`.
+- **⬆️ Управление очередью**: Веб-интерфейс показывает заполненность, лист ожидания и позволяет ГМу поднять первого игрока из очереди.
+- **🔄 Автоматическая синхронизация**: Любые изменения в веб-интерфейсе мгновенно обновляют сообщения с расписанием в Telegram-чатах игроков.
 
 ### 🌐 Web Dashboard (Blazor Server)
-- **🔐 Авторизация через Telegram**: Безопасный вход с использованием Telegram Login Widget (HMAC-SHA256 валидация).
+- **🔐 Авторизация через Telegram**: Telegram Login Widget с HMAC-SHA256 валидацией.
-- **📝 Удобное редактирование**: Веб-интерфейс для детального редактирования сессий, изменения дат, названий и статусов.
+- **📱 Telegram Mini App Dashboard**: Мобильная панель открывается из Telegram, проверяет `initData` на сервере, учитывает safe-area телефона и верхнюю панель Telegram.
-- **🔄 Автоматическая синхронизация**: Любые изменения в веб-интерфейсе мгновенно обновляют сообщения с расписанием в Telegram-чатах игроков.
+- **✏️ Редактирование**: Детальное изменение дат, названий и статусов сессий.
-- **🕒 Управление временем**: UI адаптирован под московское время (UTC+3), в то время как база данных работает в UTC.
+- **🤝 Co-GM и делегирование**: Owner назначает помощников по Telegram ID; co-GM управляет расписанием, но **не может назначать других co-GM**.
+- **📋 Шаблоны кампаний**: Вкладка `Шаблоны` отдельно от страницы группы: сохранение типовых параметров и запуск нового batch из шаблона.
+- **📦 Bulk-операции для Batch Sessions**:
+  - обновить общий `title`/`link` у всей пачки;
+  - перенести пачку на фиксированный шаг в днях;
+  - клонировать batch на следующую неделю или месяц.
+- **⬆️ Управление очередью**: Заполненность, лист ожидания и ручное повышение игрока из очереди.
+- **📜 История изменений сессий**: Страница `/session/{id}/history` показывает аудит-лог всех значимых изменений (время, ссылка, название, участники, статус) с указанием акторов и дат.
+- **📊 Статистика посещаемости**: Страница `/group/{id}/stats` показывает долю присутствия, количество пропусков и среднюю явку по каждому игроку группы.
+- **🔄 Автосинхронизация**: Изменения в вебе мгновенно перерисовывают Telegram-сообщения расписания.

 ## 🚀 Быстрый старт (Docker Compose)
 
-Проект использует Docker Compose для одновременного запуска базы данных, бота и веб-интерфейса.
+**Требования:** Docker и Docker Compose.
-
-### 1. Подготовка
-Убедитесь, что у вас установлены **Docker** и **Docker Compose**.
-
-### 2. Настройка окружения
-Скопируйте файл-шаблон и заполните его значениями:
 
+### 1. Настройка окружения
 ```bash
 cp .env.example .env
 ```
 
-Отредактируйте `.env`:
+**Ключевые переменные `.env`:**
-
 ```env
-# Токен вашего бота от @BotFather (используется и для бота, и как секретный ключ для веб-авторизации)
+# Токен от @BotFather (используется ботом и как секретный ключ веб-авторизации)
 TELEGRAM_BOT_TOKEN=ваш_токен_здесь
 
-# Имя вашего бота в Telegram (без @), например: GmRelayBot.
+# Имя бота без @ (для Telegram Login Widget)
-# Найти его можно в информации о боте у @BotFather. 
-# Используется для работы виджета авторизации (Telegram Login Widget).
 TELEGRAM_BOT_USERNAME=ваше_имя_бота_здесь
 
-# Пароль для базы данных PostgreSQL
+# HTTPS URL Mini App, например https://your-domain.example/miniapp
+TELEGRAM_MINI_APP_URL=https://your-domain.example/miniapp
+
 POSTGRES_PASSWORD=ваш_надежный_пароль
+GMRELAY_WEB_PORT=8080
 ```
 
-*(Опционально)* Настройте домен Telegram бота в @BotFather командой `/setdomain` для работы виджета авторизации на вашем сайте.
+**Настройка в @BotFather:**
+- Команда `/setdomain` для работы виджета авторизации на вашем домене.
+- Для Mini App настройте домен Web Dashboard и menu button на URL из `TELEGRAM_MINI_APP_URL`.
+- Начиная с **v1.9.3** дополнительных действий для фикса входа не требуется: fallback выполняется внутри активного Telegram WebView по тому же HTTPS-адресу `/miniapp`.
 
-### 3. Запуск
+### 2. Запуск
-Выполните команду:
 ```bash
-docker compose up -d -build
+docker compose up -d
-```
-Инфраструктура автоматически:
-- Поднимет PostgreSQL.
-- Запустит бота (применив миграции БД).
-- Запустит веб-интерфейс (доступен по умолчанию на порту **8080** внутри контейнера).
-
----
-
-## ⚙️ Настройка бота в Telegram
-
-Чтобы бот работал корректно:
-1. **Добавьте бота в группу** (или Супергруппу/Форум).
-2. **Назначьте бота Администратором**. 
-3. **Необходимые права**:
-    * `Выбор тем` (Managed Topics) — **обязательно** для Форумов.
-    * `Отправка сообщений`.
-    * `Закрепление сообщений` — рекомендуется.
-
-> [!TIP]
-> Колонку "Мастер" (GM) бот определяет по первому человеку, который создал сессию в этой группе. Только этот пользователь сможет отменять игры через кнопки бота и редактировать их в веб-интерфейсе.
-
----
-
-## 📝 Инструкция для Мастера
-
-### Создание расписания игр
-Используйте команду `/newsession` с описанием в следующем формате:
-
-```text
-/newsession
-Название: Легенды Берега Мечей (D&D 5e)
-Время: 15.05.2024 19:30
-Время: 22.05.2024 19:00
-Ссылка: https://discord.gg/invite-link
 ```
 
-### Другие команды
+**Автоматически выполняется:**
-- `/listsessions` — Показать список всех актуальных игр в этой группе.
+- создание Docker-сети и volume PostgreSQL;
-- `/reschedulesession` — Перенести сессию на другое время с голосованием игроков.
+- подъём PostgreSQL (`db:5432`);
-- `/deletesession` — Удалить сессию.
+- запуск бота с плавной миграцией (DbUp);
-- `/exportcalendar` — Получить `.ics` файл с играми.
+- запуск веб-приложения с подключением к БД и Telegram API.
-- `/help` — Справка по формату.
+
+### 3. Первоначальная настройка
+1. Напишите боту `/start`.
+2. Создайте группу через `/newgroup`.
+3. Откройте Mini App или Web Dashboard для расширенного управления.
+
+## 💾 Backup и восстановление
+
+Проект включает автоматический ежедневный backup PostgreSQL через сервис `db-backup` в Docker Compose.
+
+### Как это работает
+- **Каждый день в 03:00** выполняется `pg_dump` базы `gmrelay_db`.
+- Дампы сжимаются (`gzip`) и сохраняются в volume `pgbackups` (`/backups`).
+- Формат имени: `gmrelay_db_YYYYMMDD_HHMMSS.sql.gz`.
+- Ротация: по умолчанию хранятся последние **7 дней** (настраивается через `BACKUP_RETENTION_DAYS`).
+
+### Проверка бэкапов
+```bash
+docker compose exec db-backup ls -la /backups
+```
+
+### Ручное создание дампа
+```bash
+docker compose exec db-backup sh -c "pg_dump -h db -U gmrelay -d gmrelay_db | gzip > /backups/gmrelay_db_manual.sql.gz"
+```
+
+### Восстановление из бэкапа
+```bash
+# Использовать последний автоматический бэкап
+./scripts/restore.sh
+
+# Или указать конкретный файл
+./scripts/restore.sh backups/gmrelay_db_20260512_030000.sql.gz
+```
+
+> [!WARNING]
+> Восстановление **перезаписывает текущую базу данных**. Убедитесь, что вы понимаете последствия, прежде чем запускать `restore.sh`.
+
+### Переменные окружения (опциональные)
+```env
+BACKUP_RETENTION_DAYS=7
+BACKUP_VOLUME_NAME=game_pgbackups
+```

+# ADR 002: Platform-Neutral Batch Rendering
+
+## Status
+
+**Accepted** — implemented in v1.10.0 (PR #42).
+
+## Context
+
+`SessionBatchRenderer` жил в `GmRelay.Shared` и напрямую зависел от `Telegram.Bot` (`InlineKeyboardMarkup`, `ParseMode.Html`). Это создавало проблемы:
+
+1. **Shared не был platform-neutral.** Любой платформенный проект (Discord, Slack, WebSocket) тащил Telegram-зависимость.
+2. **Дублирование логики.** `GmRelay.Web` использовал тот же рендерер через прямую зависимость от `Shared`, но Web — это не Telegram-клиент.
+3. **Невозможно написать unit-тесты без Telegram-объектов.** Smoke-тесты создавали InlineKeyboardMarkup даже для проверки чисто доменной логики.
+
+## Decision
+
+Разделить рендеринг на две стадии:
+
+1. **View Builder (platform-neutral)** — собирает view model из доменных DTO.
+2. **Platform Renderer (platform-specific)** — превращает view model в платформенное представление.
+
+```
+Domain DTOs
+    │
+    ▼
+SessionBatchViewBuilder (Shared)
+    │
+    ▼
+SessionBatchViewModel (platform-neutral)
+    │
+    ├──► TelegramSessionBatchRenderer ──► HTML + InlineKeyboardMarkup
+    │
+    └──► DiscordSessionBatchRenderer ──► (issue #26)
+```
+
+### Изменённые компоненты
+
+| Компонент | Было | Стало |
+|---|---|---|
+| `SessionBatchRenderer` | `GmRelay.Shared.Rendering` | Удалён |
+| `SessionBatchViewBuilder` | — | `GmRelay.Shared.Rendering` |
+| `SessionBatchViewModel` | — | `GmRelay.Shared.Rendering` |
+| `TelegramSessionBatchRenderer` | — | `GmRelay.Bot` + `GmRelay.Web` |
+| `DiscordSessionBatchRenderer` | — | `GmRelay.Shared.Rendering` (stub) |
+| `BatchMessageEditor` | `GmRelay.Shared.Rendering` | `GmRelay.Bot` + `GmRelay.Web` |
+
+## Consequences
+
+### Positive
+
+- `GmRelay.Shared` больше не зависит от `Telegram.Bot`. Чистый platform-agnostic проект.
+- Можно добавить `DiscordSessionBatchRenderer` без изменений в `Shared`.
+- Unit-тесты ViewBuilder не создают `InlineKeyboardMarkup`.
+- Логика подсчёта игроков, сортировки сессий и генерации действий — в одном месте (ViewBuilder).
+
+### Negative
+
+- **Временное дублирование.** `TelegramSessionBatchRenderer` и `BatchMessageEditor` скопированы в `Bot` и `Web`. Планируется вынести в `GmRelay.Shared.Telegram` при появлении третьего Telegram-потребителя.
+- **Дополнительная стадия.** Теперь два вызова вместо одного: `Build` + `Render`. Этоtrade-off за чистоту абстракции.
+
+## Related
+
+- Issue #22 — этот рефакторинг.
+- Issue #26 — Discord Bot MVP (потребитель новой архитектуры).
+- ADR 001 — vertical slice, native AOT, Aspire (`docs/adr/0001-use-vertical-slice-native-aot-and-aspire.md`).

+# Player List + Kick + Waitlist Promotion Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** Add a player list (with names) to the Web UI session views, allow GM to kick a specific player, and auto-promote the next waitlisted player.
+
+**Architecture:** Extend `ISessionStore` with participant queries and a remove method. Update `GroupDetails.razor` to show expandable participant lists. Reuse existing `PromoteWaitlistedPlayerAsync` logic after removal.
+
+**Tech Stack:** C# 14, Blazor SSR, Dapper, PostgreSQL
+
+---
+
+## Task 1: Add domain model for WebParticipant
+
+**Objective:** Create a DTO to represent a session participant in the web layer.
+
+**Files:**
+- Modify: `src/GmRelay.Web/Services/SessionService.cs`
+
+**Step 1: Add record**
+
+```csharp
+public sealed record WebParticipant(
+    Guid Id,
+    long TelegramId,
+    string DisplayName,
+    string? TelegramUsername,
+    string RsvpStatus,
+    string RegistrationStatus,
+    bool IsGm,
+    DateTime? RespondedAt);
+```
+
+**Step 2: Commit**
+
+```bash
+git add src/GmRelay.Web/Services/SessionService.cs
+git commit -m "feat: add WebParticipant record"
+```
+
+---
+
+## Task 2: Add GetSessionParticipantsAsync to ISessionStore
+
+**Objective:** Retrieve all participants for a session with full player info.
+
+**Files:**
+- Modify: `src/GmRelay.Web/Services/ISessionStore.cs`
+- Modify: `src/GmRelay.Web/Services/SessionService.cs`
+- Modify: `src/GmRelay.Web/Services/AuthorizedSessionService.cs`

+                 sp.created_at
+        """,
+        new { SessionId = sessionId })).ToList();
+}
+```
+
+**Step 3: Add authorized wrapper**
+
+In `AuthorizedSessionService.cs`, add:
+```csharp
+public async Task<List<WebParticipant>?> GetSessionParticipantsForGmAsync(Guid sessionId, long gmId)
+{

+# Telegram Mini App Dashboard Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a Telegram Mini App mobile dashboard that reuses the existing Web Dashboard and validates Telegram WebApp `initData` on the server.
+
+**Architecture:** Extend `TelegramAuthService` for WebApp init data, add a `/miniapp` Blazor entry page plus `/auth/telegram-webapp` endpoint, and add bot entry points through an inline WebApp button and optional menu button setup. Existing application/domain services remain the only write path.
+
+**Tech Stack:** .NET 10, Blazor Server, Telegram.Bot, xUnit, Dapper/Npgsql-backed existing services.
+

+
+- [ ] Write failing tests for valid WebApp `initData`, tampered hash, and expired auth date.
+- [ ] Run `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter TelegramAuthServiceTests`.
+- [ ] Implement WebApp HMAC verification using the Telegram `WebAppData` secret derivation.

+- [ ] Run `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter MiniAppDashboardTests`.
+- [ ] Implement `/miniapp` to post `Telegram.WebApp.initData` to `/auth/telegram-webapp`, expand/ready the Mini App, and show fallback login when opened outside Telegram.
+- [ ] Add CSS for a mobile-first Mini App shell and compact dashboard spacing.

+# Platform Messenger Contracts Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Implement issue #24 by adding platform-neutral platform identity and messaging contracts, then routing the Telegram session flows through a Telegram adapter without changing Telegram behavior.
+
+**Architecture:** Keep update routing and Telegram update parsing at the `GmRelay.Bot.Infrastructure.Telegram` boundary, but move outbound messaging decisions behind `GmRelay.Shared.Platform.IPlatformMessenger`. `GmRelay.Shared` owns platform-neutral DTOs and contracts; `GmRelay.Bot` owns `TelegramPlatformMessenger`, which translates neutral requests into `Telegram.Bot` calls and reuses the existing Telegram renderers/editing rules.
+
+**Tech Stack:** .NET 10, C# preview, xUnit, Dapper.AOT constraints, Telegram.Bot in `GmRelay.Bot` only, platform-neutral shared contracts in `GmRelay.Shared`.
+
+---
+
+## Issue Context
+
+- Gitea issue: #24, `refactor: ввести PlatformKind, PlatformUser, PlatformGroup и IPlatformMessenger`
+- Labels: `area:bot`, `area:platform`, `area:shared`, `platform:multi`, `type:refactor`, `pending-approval`
+- Acceptance criteria:
+  - New contracts live in a platform-neutral layer.
+  - Telegram flow goes through the adapter without behavior changes.
+  - A future DiscordBot can reference the contract without depending on Telegram assemblies.
+
+## Proposed Version Bump
+
+Current version is `2.0.0` in:
+
+- `Directory.Build.props`
+- `compose.yaml`
+- `.gitea/workflows/deploy.yml`
+- `src/GmRelay.Web/Components/Layout/NavMenu.razor`
+
+Issue label is `type:refactor`; per workflow rules this is not a major bump and has no user-facing feature label. Proposed bump: `2.0.0` -> `2.0.1`.

+
+## Design
+
+### Shared Contracts
+
+`PlatformKind` is a sentinel enum where `Max` is not a sendable platform:
+
+```csharp
+namespace GmRelay.Shared.Platform;
+
+public enum PlatformKind
+{
+    Telegram = 0,
+    Discord = 1,
+    Max = 2
+}
+```
+
+`PlatformUser` and `PlatformGroup` carry external platform identity while keeping current Telegram IDs representable as strings:
+
+```csharp
+namespace GmRelay.Shared.Platform;
+
+public sealed record PlatformUser(
+    PlatformKind Platform,
+    string ExternalUserId,
+    string DisplayName,
+    string? ExternalUsername);
+
+public sealed record PlatformGroup(
+    PlatformKind Platform,
+    string ExternalGroupId,
+    string DisplayName,
+    string? ExternalChannelId = null,
+    string? ExternalThreadId = null);
+```
+
+Outbound message contracts stay independent of Telegram/Discord SDK types:
+
+```csharp
+using GmRelay.Shared.Rendering;
+
+namespace GmRelay.Shared.Platform;
+
+public sealed record PlatformMessageRef(
+    PlatformKind Platform,
+    string ExternalGroupId,
+    string? ExternalThreadId,
+    string ExternalMessageId);
+
+public sealed record PlatformMessageAction(
+    string Key,
+    string Label,
+    string Payload);
+
+public sealed record PlatformScheduleMessage(
+    PlatformGroup Group,
+    SessionBatchViewModel View,
+    PlatformMessageRef? ExistingMessage,
+    string? ImageReference = null);
+
+public sealed record PlatformPrivateMessage(
+    PlatformUser Recipient,
+    string HtmlText);
+
+public sealed record PlatformInteractionReply(
+    string InteractionId,
+    string Text,
+    bool ShowAlert = false);
+
+public sealed record PlatformCalendarFile(
+    PlatformGroup Group,
+    string FileName,
+    byte[] Content,
+    string CaptionHtml,
+    IReadOnlyList<PlatformMessageAction> Actions);
+```
+
+`IPlatformMessenger` exposes the required outward operations:
+
+```csharp
+namespace GmRelay.Shared.Platform;
+
+public interface IPlatformMessenger
+{
+    Task<PlatformMessageRef> SendScheduleAsync(PlatformScheduleMessage message, CancellationToken ct);
+    Task UpdateScheduleAsync(PlatformScheduleMessage message, CancellationToken ct);
+    Task SendGroupMessageAsync(PlatformGroup group, string htmlText, CancellationToken ct);
+    Task SendPrivateMessageAsync(PlatformPrivateMessage message, CancellationToken ct);
+    Task AnswerInteractionAsync(PlatformInteractionReply reply, CancellationToken ct);
+    Task SendCalendarFileAsync(PlatformCalendarFile file, CancellationToken ct);
+}
+```
+
+### Telegram Adapter
+
+`TelegramPlatformMessenger` lives in `GmRelay.Bot.Infrastructure.Telegram`, depends on `ITelegramBotClient`, and translates neutral DTOs to existing Telegram calls:
+
+- `SendScheduleAsync` renders `SessionBatchViewModel` with `TelegramSessionBatchRenderer.Render`.
+- `UpdateScheduleAsync` calls `BatchMessageEditor.EditBatchMessageAsync`.
+- `SendGroupMessageAsync` calls `SendMessage` with `ParseMode.Html` and optional `messageThreadId`.
+- `SendPrivateMessageAsync` calls `SendMessage` to `PlatformUser.ExternalUserId`.
+- `AnswerInteractionAsync` calls `AnswerCallbackQuery`.
+- `SendCalendarFileAsync` calls `SendDocument` and maps URL actions to inline keyboard buttons.
+
+### Handler Scope
+
+Refactor outbound Telegram calls in these flows to `IPlatformMessenger`:
+
+- Join/leave/promote waitlist schedule updates and callback replies.
+- Cancel schedule update, group cancellation message, direct notification and callback reply.
+- Reschedule initiation, voting message updates, immediate reschedule schedule update, direct notifications and callback replies.
+- Export calendar file sending.
+
+Keep Telegram inbound DTOs at the boundary for now:
+
+- `UpdateRouter` still receives `Telegram.Bot.Types.Update`.
+- Text message parsing in reschedule input still receives `Telegram.Bot.Types.Message`.
+- `CreateSessionHandler` can keep photo/topic creation via `ITelegramBotClient` because issue #24 targets outbound schedule/interaction/private/calendar contract, not replacing all Telegram update primitives in one PR.
+
+## Tasks
+
+### Task 1: RED - Shared Contract Tests

+            []);
+        var group = new PlatformGroup(PlatformKind.Discord, "guild-1", "Guild", "channel-1", "thread-1");

+        }
+
+        throw new FileNotFoundException($"Could not locate repository file '{relativePath}'.");
+    }

+```
+
+- [ ] **Step 2: Run tests and verify RED**
+
+Run:
+
+```powershell
+dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter TelegramPlatformMessengerSourceTests
+```
+
+Expected: failures because `TelegramPlatformMessenger` is missing and handlers still call Telegram APIs directly.
+
+### Task 4: GREEN - Implement TelegramPlatformMessenger and Registration
+
+**Files:**
+- Create: `src/GmRelay.Bot/Infrastructure/Telegram/TelegramPlatformMessenger.cs`
+- Modify: `src/GmRelay.Bot/Program.cs`
+
+- [ ] **Step 1: Implement adapter**
+
+Implementation notes:
+
+- Parse Telegram chat/thread/message IDs from neutral string IDs with `long.Parse` and `int.Parse`.
+- Use `ParseMode.Html` for HTML text.
+- Map `PlatformMessageAction` URLs to `InlineKeyboardButton.WithUrl`.
+- Return a `PlatformMessageRef` with message IDs converted to strings.
+
+- [ ] **Step 2: Register adapter**
+
+Add `using GmRelay.Shared.Platform;` and register:
+
+```csharp
+builder.Services.AddSingleton<IPlatformMessenger, TelegramPlatformMessenger>();
+```
+
+- [ ] **Step 3: Run adapter source tests**
+
+Run:
+
+```powershell
+dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter TelegramPlatformMessengerSourceTests
+```
+
+Expected: some handler source tests still fail until Task 5.
+
+### Task 5: GREEN - Refactor Session Flows Through Adapter
+
+**Files:**
+- Modify target handler files listed in Task 3
+- Modify: `src/GmRelay.Bot/Features/Notifications/DirectSessionNotificationSender.cs`
+
+- [ ] **Step 1: Replace constructor dependencies**
+
+Use `IPlatformMessenger messenger` in target handlers for outbound operations. Keep `ITelegramBotClient` only where the handler still performs inbound Telegram-specific work that is out of scope, such as message deletion or forum topic creation.
+
+- [ ] **Step 2: Convert Telegram IDs to neutral platform objects**
+
+Use helper code equivalent to:
+
+```csharp
+private static PlatformGroup TelegramGroup(long chatId, string? title, int? threadId = null)
+    => new(
+        PlatformKind.Telegram,
+        chatId.ToString(System.Globalization.CultureInfo.InvariantCulture),
+        title ?? "Telegram chat",
+        ExternalChannelId: chatId.ToString(System.Globalization.CultureInfo.InvariantCulture),
+        ExternalThreadId: threadId?.ToString(System.Globalization.CultureInfo.InvariantCulture));
+
+private static PlatformUser TelegramUser(long telegramId, string displayName, string? username = null)
+    => new(
+        PlatformKind.Telegram,
+        telegramId.ToString(System.Globalization.CultureInfo.InvariantCulture),
+        displayName,
+        username);
+```
+
+- [ ] **Step 3: Replace schedule updates**
+
+Build `SessionBatchViewModel` as before, then call:
+
+```csharp
+await messenger.UpdateScheduleAsync(
+    new PlatformScheduleMessage(
+        group,
+        view,
+        new PlatformMessageRef(PlatformKind.Telegram, group.ExternalGroupId, group.ExternalThreadId, messageId.ToString(System.Globalization.CultureInfo.InvariantCulture))),
+    ct);
+```
+
+- [ ] **Step 4: Replace interaction replies**
+
+Use:
+
+```csharp
+await messenger.AnswerInteractionAsync(
+    new PlatformInteractionReply(command.CallbackQueryId, text, showAlert: false),
+    ct);
+```
+
+- [ ] **Step 5: Replace direct notifications**
+
+`DirectSessionNotificationSender` should become a small compatibility service over `IPlatformMessenger`:
+
+```csharp
+await messenger.SendPrivateMessageAsync(
+    new PlatformPrivateMessage(
+        new PlatformUser(PlatformKind.Telegram, recipient.TelegramId.ToString(CultureInfo.InvariantCulture), recipient.DisplayName, null),
+        htmlText),
+    ct);
+```
+
+- [ ] **Step 6: Replace calendar file sending**
+
+`ExportCalendarHandler` builds the same ICS bytes and calls `SendCalendarFileAsync`, preserving the subscription URL button as a `PlatformMessageAction`.
+
+- [ ] **Step 7: Run target source tests**
+
+Run:
+
+```powershell
+dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter TelegramPlatformMessengerSourceTests
+```
+
+Expected: `Passed`.
+
+### Task 6: Regression Tests
+
+**Files:**
+- Existing tests only unless a compiler failure exposes a missing using or changed behavior.
+
+- [ ] **Step 1: Run rendering and routing tests**
+
+Run:
+
+```powershell
+dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter "FullyQualifiedName~Rendering|FullyQualifiedName~Telegram|FullyQualifiedName~RescheduleSession"
+```
+
+Expected: `Passed`.
+
+- [ ] **Step 2: Run all tests**
+
+Run:
+
+```powershell
+dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj
+```
+
+Expected: `Passed`.
+
+- [ ] **Step 3: Build solution**
+
+Run:
+
+```powershell
+dotnet build GM-Relay.slnx

+Expected: no `2.0.0` matches in these files and `2.0.1` appears in all required locations.
+
+### Task 8: Documentation Review
+
+**Files:**
+- Review: `README.md`
+- Review: `docs/adr/002-platform-neutral-batch-rendering.md`
+
+- [ ] **Step 1: Check README and ADR for platform contract accuracy**
+- [ ] **Step 2: Update docs if they now misrepresent platform-neutral responsibilities**
+
+Expected likely doc change: README currently lists current version as `v1.15.0`, which is already inconsistent with repo version `2.0.0`. If this PR bumps to `2.0.1`, update that line to `v2.0.1`.
+
+### Task 9: Commit, PR, CI, Review, Merge, Deploy, Release
+
+**Files:**
+- Stage only files intentionally changed for issue #24.
+
+- [ ] **Step 1: Create branch**
+
+```powershell

+```
+
+- [ ] **Step 3: Push and create PR via Gitea**
+- [ ] **Step 4: Wait for PR CI and fix failures if any**

+- [ ] **Step 6: Merge PR after CI and review**
+- [ ] **Step 7: Monitor deploy workflow**
+- [ ] **Step 8: Create release `v2.0.1` with Russian release notes**
+- [ ] **Step 9: Close issue #24 with PR and release links**
+
+## Self-Review
+
+- Spec coverage: all issue acceptance criteria map to Shared contracts, Telegram adapter, handler source tests, and build/test verification.
+- Placeholder scan: no `TBD`, `TODO`, or "fill later" placeholders are left in this plan.
+- Type consistency: all snippets use `GmRelay.Shared.Platform`, `PlatformKind.Telegram`, `PlatformMessageRef`, and `IPlatformMessenger` consistently.
+- Scope control: inbound Telegram update parsing remains out of scope; outbound schedule/private/interaction/calendar operations are in scope.

+# Platform-Neutral Join Leave Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Implement Gitea issue #25 by making join/leave session interactions use platform-neutral command models while preserving Telegram callback behavior, seat limits, and waitlist semantics.
+
+**Architecture:** Telegram callback routing remains in `UpdateRouter`, but it becomes an adapter that converts callback data into `PlatformUser`, `PlatformGroup`, and `PlatformMessageRef` values. `JoinSessionHandler` and `LeaveSessionHandler` operate on those neutral values, persist players by `(platform, external_user_id)`, and update schedules through `IPlatformMessenger`.
+
+**Tech Stack:** .NET 10, xUnit, Dapper, Npgsql, Gitea Actions.
+

+
+## Issue Context
+
+- Issue: `#25 refactor: obobshchit JoinSession i LeaveSession pod platform-neutral interactions`
+- Labels: `area:bot`, `area:platform`, `area:shared`, `platform:multi`, `type:refactor`
+- Version bump: patch, `2.1.0` -> `2.1.1`. The issue is labeled refactor, not breaking; do not use a major bump without explicit approval.
+- Existing untracked file: `CLAUDE.md`; do not stage or modify it.
+
+## File Map
+
+- Create: `tests/GmRelay.Bot.Tests/Features/Sessions/CreateSession/PlatformNeutralSessionInteractionCommandTests.cs`
+  - Reflection tests proving join/leave command records expose neutral properties and no Telegram-specific identity/message fields.
+- Create: `tests/GmRelay.Bot.Tests/Features/Sessions/CreateSession/PlatformNeutralSessionInteractionSqlTests.cs`
+  - Source-level regression tests for handler SQL and messenger boundaries.
+- Modify: `tests/GmRelay.Bot.Tests/Infrastructure/Database/PlatformIdentityMigrationTests.cs`
+  - Add a migration test for nullable legacy `players.telegram_id`, required for non-Telegram player inserts.
+- Create: `src/GmRelay.Bot/Migrations/V017__allow_platform_neutral_players.sql`
+  - Drop `NOT NULL` from legacy Telegram-only player columns.
+- Modify: `src/GmRelay.Bot/Features/Sessions/CreateSession/JoinSessionHandler.cs`
+  - Change `JoinSessionCommand` to neutral properties and query/upsert players by platform identity.
+- Modify: `src/GmRelay.Bot/Features/Sessions/CreateSession/LeaveSessionHandler.cs`
+  - Change `LeaveSessionCommand` to neutral properties and find participants by platform identity.
+- Modify: `src/GmRelay.Bot/Infrastructure/Telegram/UpdateRouter.cs`
+  - Convert Telegram callback data into neutral command values using `TelegramPlatformIds`.
+- Modify: version files after implementation:
+  - `Directory.Build.props`
+  - `compose.yaml`
+  - `.gitea/workflows/deploy.yml`
+  - `src/GmRelay.Web/Components/Layout/NavMenu.razor`

+## Task 4: GREEN - Refactor JoinSessionCommand and Handler
+
+**Files:**
+- Modify: `src/GmRelay.Bot/Features/Sessions/CreateSession/JoinSessionHandler.cs`
+
+- [ ] **Step 1: Replace command record**
+
+Replace the existing `JoinSessionCommand` declaration with:
+
+```csharp
+public sealed record JoinSessionCommand(
+    Guid SessionId,
+    PlatformUser User,
+    string InteractionId,
+    PlatformGroup Group,
+    PlatformMessageRef ScheduleMessage);

+
+Add `using System.Globalization;` at the top.
+
+- [ ] **Step 3: Update participant display query**
+
+Change the participant projection to prefer platform-neutral username:
+
+```sql
+COALESCE(p.external_username, p.telegram_username) as TelegramUsername
+```
+
+- [ ] **Step 4: Update schedule message and interaction reply usage**
+
+Use:

+
+```csharp
+private Task AnswerAsync(string interactionId, string text, CancellationToken ct) =>

+- [ ] **Step 5: Verify command and SQL tests for join**
+
+Run:
+
+```powershell
+dotnet test .\tests\GmRelay.Bot.Tests\GmRelay.Bot.Tests.csproj --filter "JoinSessionCommand_ShouldExposePlatformNeutralInteractionContext|JoinSessionHandler_ShouldPersistPlayersByPlatformIdentity"

+
+Expected: PASS for join-focused tests.
+
+## Task 5: GREEN - Refactor LeaveSessionCommand and Handler
+
+**Files:**
+- Modify: `src/GmRelay.Bot/Features/Sessions/CreateSession/LeaveSessionHandler.cs`

+- [ ] **Step 3: Update participant display query**
+
+Change the participant projection to:
+
+```sql
+COALESCE(p.external_username, p.telegram_username) AS TelegramUsername
+```
+
+- [ ] **Step 4: Update schedule message and interaction reply usage**
+
+Use:

+        command.Group,
+        view,
+        command.ScheduleMessage),

+
+## Task 6: GREEN - Convert Telegram Router to Neutral Commands
+
+**Files:**
+- Modify: `src/GmRelay.Bot/Infrastructure/Telegram/UpdateRouter.cs`
+
+- [ ] **Step 1: Add local conversion values in `HandleCallbackQueryAsync`**
+
+After parsing `action`, add:

+Use Gitea MCP for PR creation, CI polling, review, merge, deploy monitoring, and release `v2.1.1`. Close issue #25 after release and add a comment linking the PR and release.
+
+## Self-Review
+
+- Spec coverage: issue scope is covered by neutral command records, Telegram adapter conversion, platform identity SQL, messenger-based schedule updates, and tests.

+# Telegram Mini App Dashboard Design
+
+## Goal
+
+Issue #17 adds a Telegram Mini App dashboard as the mobile entry point for the existing Web Dashboard. Owner and co-GM users must be able to open the dashboard from Telegram, pass server-side Telegram WebApp `initData` validation, and manage only their own groups.
+
+## Scope
+
+- Add Mini App authentication using Telegram WebApp `initData`.
+- Add a `/miniapp` entry page that signs the user into the existing cookie auth flow, then opens the regular dashboard UI in mobile-first mode.
+- Reuse `AuthorizedSessionService`, `SessionService`, and existing Blazor pages for groups, sessions, templates, waitlist promotion, edit forms, and bulk batch operations.
+- Add bot entry points: a Mini App button in `/start` and a configurable default menu button when `Telegram:MiniAppUrl` is set.
+- Update README, wiki, deployment config, and visible version strings to `1.9.0`.
+
+## Architecture
+
+The Mini App is not a second dashboard implementation. It is a Telegram-authenticated entrance into the existing Blazor dashboard. This keeps authorization, domain operations, Telegram message synchronization, and Web Dashboard behavior in one place.
+
+`TelegramAuthService` gains a second verification method for WebApp `initData`. The server accepts the raw URL-encoded init payload at `/auth/telegram-webapp`, verifies the Telegram HMAC with the bot token, extracts the user id/name from the embedded `user` JSON, and issues the same auth cookie as the login widget endpoint.
+
+`/miniapp` loads `telegram-web-app.js`, posts `window.Telegram.WebApp.initData` to the server endpoint, expands the WebApp viewport, and redirects to `/`. If a user opens `/miniapp` outside Telegram, the page shows the regular login fallback.
+
+## Data Flow
+
+1. User opens the Mini App from the bot menu button or `/start` inline button.
+2. Telegram injects `initData` into the WebApp JavaScript API.
+3. `/miniapp` posts `{ initData }` to `/auth/telegram-webapp`.
+4. The server verifies the WebApp signature and expiry.
+5. The server creates the same claims used by Telegram Login Widget.
+6. Existing Blazor pages load groups through `AuthorizedSessionService`.
+7. Any edit, waitlist, template, or batch action still goes through existing services and keeps Telegram messages synchronized.
+
+## Error Handling
+
+- Missing or invalid init data returns `401` and leaves the user on the Mini App page.
+- Expired auth data is rejected with the same 24-hour window used by the Login Widget.
+- A verified Telegram user with no owner/co-GM groups sees the existing empty dashboard state.
+- Direct navigation to a foreign group/session still redirects to `/access-denied` through existing authorization checks.
+
+## Testing
+
+- Unit tests cover valid and invalid WebApp `initData`.
+- File-level regression tests ensure `/miniapp`, `/auth/telegram-webapp`, Telegram WebApp script loading, bot Mini App button, menu button setup, and mobile Mini App CSS hooks remain present.
+- Existing `AuthorizedSessionServiceTests` continue covering owner/co-GM access behavior.
