 - **📝 Удобное редактирование**: Веб-интерфейс для детального редактирования сессий, изменения дат, названий и статусов.

+# 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.
+
+---
+
+### Task 1: Telegram WebApp Authentication
+
+**Files:**
+- Modify: `src/GmRelay.Web/Services/TelegramAuthService.cs`
+- Modify: `src/GmRelay.Web/Program.cs`
+- Test: `tests/GmRelay.Bot.Tests/Web/TelegramAuthServiceTests.cs`
+
+- [ ] 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.
+- [ ] Add `/auth/telegram-webapp` endpoint that signs in using the same claims as `/auth/telegram`.
+- [ ] Re-run the filtered tests.
+
+### Task 2: Mini App Entry Page
+
+**Files:**
+- Create: `src/GmRelay.Web/Components/Pages/MiniApp.razor`

+- [ ] Write failing tests that assert `/miniapp`, `telegram-web-app.js`, `authenticateTelegramMiniApp`, and Mini App CSS hooks exist.
+- [ ] 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.
+- [ ] Re-run the filtered tests.
+
+### Task 3: Bot Entry Points
+
+**Files:**
+- Create: `src/GmRelay.Bot/Infrastructure/Telegram/TelegramMiniAppMenuButtonService.cs`

+- Modify: `src/GmRelay.Bot/Program.cs`
+- Test: `tests/GmRelay.Bot.Tests/Infrastructure/Telegram/TelegramMiniAppEntryPointTests.cs`
+
+- [ ] Write failing tests that assert `/start` exposes a WebApp button and startup registers the menu button service.
+- [ ] Run `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter TelegramMiniAppEntryPointTests`.
+- [ ] Add a configurable `Telegram:MiniAppUrl` entry point; when missing, keep existing command behavior.
+- [ ] Add hosted service that calls `SetChatMenuButton` with `MenuButtonWebApp` only when the URL is configured.
+- [ ] Re-run the filtered tests.
+
+### Task 4: Docs, Versions, and Release Prep
+
+**Files:**
+- Modify: `Directory.Build.props`

+
+- [ ] Update project/container/workflow/UI versions to `1.9.0`.
+- [ ] Document `TELEGRAM_MINI_APP_URL`, BotFather `/setmenubutton`, `/miniapp`, and WebApp auth.
+- [ ] Run `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --collect:"XPlat Code Coverage"`.
+- [ ] Run `dotnet build GM-Relay.slnx -c Release`.

+# 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.
