fix(web): include PublicationMode/IsMembersOnly in showcase SQL to fix /showcase 500

Dapper.AOT generated a 19-parameter ctor for ShowcaseSessionRow based on the
SELECT list in GetShowcaseSessionsAsync / GetShowcaseSessionAsync. After
adding PublicationMode and IsMembersOnly to ShowcaseSessionDto in v3.7.0 the
record itself was extended, but the SELECT still returned 19 columns, so the
materializer threw "A parameterless default constructor or one matching
signature (...) is required" and every request to /showcase returned 500.

Add s.publication_mode and (s.publication_mode = 'ClubOnly') to both SELECT
lists and propagate them through the ShowcaseSessionDto construction. The
field list now matches the generated constructor exactly.

Version bump 3.7.0 -> 3.7.1 (patch).

+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Build, Test, and Development Commands
+
+This is a .NET 10 solution using the modern XML-based `.slnx` format. The global SDK version is `10.0.100` with `rollForward: latestFeature`.
+
+**Build the solution:**
+```bash
+dotnet build
+```
+
+**Build individual projects (the CI does this to include SAST via SecurityCodeScan):**
+```bash
+dotnet build src/GmRelay.Shared/GmRelay.Shared.csproj --no-restore
+dotnet build src/GmRelay.Bot/GmRelay.Bot.csproj --no-restore
+dotnet build src/GmRelay.Web/GmRelay.Web.csproj --no-restore
+```
+
+**Run all tests:**
+```bash
+dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --verbosity normal
+```
+
+**Run a single test class or method:**
+```bash
+dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter "FullyQualifiedName~YourTestClassName"
+```
+
+**Lint and format:**
+```bash
+dotnet format --verify-no-changes --verbosity diagnostic   # CI enforcement
+dotnet format                                                  # Apply fixes
+```
+
+**Check for vulnerable packages:**
+```bash
+dotnet list package --vulnerable --include-transitive
+```
+
+**Restore with lock file verification:**
+The repo enforces `RestorePackagesWithLockFile=true`. After adding or updating packages, commit the updated `packages.lock.json` files or the Trivy scan in CI will fail.
+
+**Run locally with Aspire (dev orchestration):**
+```bash
+dotnet run --project src/GmRelay.AppHost/GmRelay.AppHost.csproj
+```
+This automatically starts PostgreSQL in a container, the Bot, and the Web dashboard.
+
+**Run locally with Docker Compose (production-like):**
+```bash
+cp .env.example .env
+# Edit .env with your TELEGRAM_BOT_TOKEN, TELEGRAM_BOT_USERNAME, POSTGRES_PASSWORD
+docker compose up -d
+```
+
+## High-Level Architecture
+
+### Project Roles and Runtime Model
+
+| Project | Runtime | Key Trait |
+|---|---|---|
+| `GmRelay.Bot` | `Microsoft.NET.Sdk.Worker` | **Native AOT** binary. Telegram long polling bot + stateless scheduler. |
+| `GmRelay.Web` | `Microsoft.NET.Sdk.Web` | Blazor Server dashboard. Cookie auth via Telegram Login Widget / Mini App `initData`. |
+| `GmRelay.Shared` | Plain library | Domain models and platform-neutral view builders. **Must not depend on `Telegram.Bot`**. |
+| `GmRelay.ServiceDefaults` | Aspire shared project | OpenTelemetry, health checks, HTTP resilience. Referenced by both Bot and Web. |
+| `GmRelay.AppHost` | Aspire orchestrator | Dev-only. Spins up PostgreSQL and wires Bot + Web with service discovery. |
+
+**Important:** `README.md` references `GmRelay.Migrator` and `GmRelay.Worker`, but these projects do not exist. Migrations (`DbUp`) and background workers (`BackgroundService`) live inside `GmRelay.Bot`.
+
+### Vertical Slice Architecture with Explicit DI
+
+Each use case is a self-contained vertical slice: a C# record (Command/Query) + Handler class with all logic (SQL, Telegram API calls, validation). There are no abstract repository interfaces or service layers.
+
+Because the Bot is compiled as Native AOT (`PublishAot=true`, `EnableTrimAnalyzer=true`), **all DI registrations are explicit** in `src/GmRelay.Bot/Program.cs`. There is no assembly scanning or reflection-based discovery. When adding a new handler, you must register it manually in Program.cs.
+
+### Database Access: Npgsql + Dapper.AOT + DbUp
+
+**No EF Core** — it is incompatible with Native AOT. The stack is:
+- **Npgsql** ADO.NET for connections.
+- **Dapper 2.1.72** with **Dapper.AOT 1.0.48** for compile-time source-generated mapping (AOT-safe).
+- **DbUp 7.0.1** for migrations. SQL scripts are embedded resources in `src/GmRelay.Bot/Migrations/` (V001 through V015).
+- `DbMigrator.MigrateUp()` runs on every Bot startup.
+
+Both Bot and Web share the same PostgreSQL database. Web registers `NpgsqlDataSource` via `builder.AddNpgsqlDataSource("gmrelaydb")` (Aspire integration), while Bot registers it manually to avoid reflection-based Aspire configuration at AOT time.
+
+### Platform-Neutral Rendering (ADR-002)
+
+Rendering is split into two stages:
+1. **View Builder** (`GmRelay.Shared`) — platform-agnostic view model from domain DTOs.
+2. **Platform Renderer** — `TelegramSessionBatchRenderer` lives in both `GmRelay.Bot` and `GmRelay.Web` (temporary duplication until a third Telegram consumer justifies extracting `GmRelay.Shared.Telegram`).
+
+This means `GmRelay.Shared` must remain free of `Telegram.Bot` types. If you need to add rendering logic that produces `InlineKeyboardMarkup`, it belongs in the Bot or Web project, not Shared.
+
+### Stateless Scheduling
+
+The session scheduler (`SessionSchedulerService`) is a `BackgroundService` with a `PeriodicTimer(TimeSpan.FromMinutes(1))`. On each tick it queries PostgreSQL for sessions needing action (T-24h confirmation, T-5min join link) and updates their status. There is no in-memory state — the database is the single source of truth. This design was chosen specifically because Quartz.NET is incompatible with Native AOT.
+
+### Health Checks
+
+- **Bot:** Custom `BotHealthCheckHostedService` listens on port 8081. The Docker health check hits `localhost:8081/health`.
+- **Web:** Standard ASP.NET Core health checks on `/health` (JSON response with status and timestamp) and `/alive` (liveness probe tag filter). Exposed via `GmRelay.ServiceDefaults`.
+
+### Authentication and Security
+
+- **Telegram Login Widget** and **Mini App `initData`** verification via HMAC-SHA256. Cookie auth is hardened (`HttpOnly`, `SecurePolicy.Always`, `SameSite.Strict`).
+- Web Data Protection keys are persisted to `/app/dataprotection-keys` (Docker volume `web_keys`).
+- Security headers middleware (`X-Content-Type-Options`, `X-Frame-Options`, `Referrer-Policy`, `Permissions-Policy`) is applied globally in Web.
+- `SecurityCodeScan.VS2019` (5.6.7) is included in all projects via `Directory.Build.props` for SAST at build time.
+- Connection string passwords are redacted in logs via `SecretRedactor`.
+
+### CI/CD Pipeline
+
+`.gitea/workflows/pr-checks.yml` runs on every PR to `main`:
+1. `dotnet restore`
+2. Verify `packages.lock.json` files exist for Trivy
+3. `dotnet format --verify-no-changes`
+4. `dotnet list package --vulnerable`
+5. Trivy filesystem scan (`vuln,misconfig,secret`, HIGH/CRITICAL)
+6. Build Shared → Bot → Web
+7. Run tests
+
+`.gitea/workflows/deploy.yml` runs on push to `main`:
+1. Build and push `gmrelay-bot` and `gmrelay-web` images to `git.codeanddice.ru/toutsu/...`
+2. Trivy image scan on both images (HIGH/CRITICAL, exit-code 1)
+3. Create `.env` from secrets and run `docker compose up -d`
+
+### Environment Configuration
+
+Key environment variables (see `.env.example`):
+- `TELEGRAM_BOT_TOKEN`, `TELEGRAM_BOT_USERNAME`, `TELEGRAM_MINI_APP_URL`
+- `POSTGRES_PASSWORD`
+- `GMRELAY_WEB_PORT` (default 8080)
+- `ConnectionStrings__gmrelaydb` — used by both Bot and Web
+
+The Bot reads config as `Telegram:BotToken` (colon) which maps from `Telegram__BotToken` (double underscore) via environment variables.
+
+### Docker Images
+
+- **Bot:** Multi-stage Dockerfile. Build stage uses `sdk:10.0-noble` with `clang` and `zlib1g-dev` for AOT compilation. Final stage uses `runtime-deps:10.0-noble`. Exposes 8081.
+- **Web:** Multi-stage Dockerfile. Build stage uses `sdk:10.0-noble`. Final stage uses `aspnet:10.0-noble` with `libgssapi-krb5-2` and `wget`. Exposes 8080.
+
+Both images are built for multi-arch (`linux/amd64`, `linux/arm64`) to support Raspberry Pi 5 (ARM64) deployment.

+- **📅 Создание расписаний (Batch Sessions)**: Создавайте сразу несколько игр одним сообщением изменения (на недельный месяц в перед).
+- **🖼 Обложки расписаний**: И batch-посту можно прикрепить фото к `/newsession` или указать строку `Картинка: https://...`; бот отправит обложку перед сообщением записи.
 - **⚡ Быстрые повторы расписания**: Для регулярной кампании можно указать одну дату, количество игр и интервал, а бот сам развернёт повторяющийся batch.
 - **✋ Интерактивная запись и выход**: Игроки записываются на конкретные даты и самостоятельно снимают запись нажатием одной кнопки.
 - **👥 Лимит мест и лист ожидания**: ГМ задаёт максимальный состав, бот не переполняет сессию, автоматически ведёт очередь ожидания и освобождённое место отдаёт первому ожидающему.
-- **📁 Поддержка Форумов (Telegram Topics)**: Бот автоматически создает тему во вложенных чатах Telegram под каждую новую пачку игр.
-- **❌ Управление сессиями**: Owner и назначенные co-GM могут создавать, отменять, удалять и переносить игры прямо из Telegram.
-- **🔄 Голосование за перенос**: При переносе сессии GM предлагает 2-3 новых времени и дедлайн, игроки голосуют кнопками, а бот показывает текущие результаты и применяет победивший вариант.
-- **🔔 Персональные уведомления**: Игроки получают DM о RSVP за 24 часа, напоминание за 1 час, ссылку перед игрой, отмены и переносы; групповые уведомления при этом остаются.
-- **🗓 Экспорт в Календарь**: Генерация файла `.ics` для добавления всех игр в Google, Apple или Яндекс Календарь одной командой.
-- **🚀 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 подключенных Telegram- и Discord-каналах.
+
+### Discord Bot
+- **Slash-команды `/newsession` и `/listsessions`**: GM создаёт сессии и публикует актуальное расписание прямо в Discord-канале.
+- **Кнопки Join/Leave с ephemeral-ответами**: игроки нажимают Join/Leave в Discord-сообщении; бот отвечает ephemeral-сообщением и обновляет schedule message.
+- **RSVP (подтверждения) за 24ч до сессии**: scheduler публикует запрос подтверждения в Discord-канале, игроки отвечают кнопками, а GM получает итоги RSVP.
+- **DM-напоминания за 1ч и ссылки перед игрой**: one-hour reminders и join-link notifications отправляются в Discord DM при включённых личных уведомлениях; сбои DM логируются без публичного fallback.
+- **Reschedule voting (голосование за перенос)**: deadline-сервис обновляет Discord vote message и schedule message через `IPlatformMessenger`.
+- **Лимиты и waitlist**: при заполненном составе игрок попадает в waitlist, а при выходе участника первый ожидающий автоматически продвигается в основной состав.
 
 ### 🌐 Web Dashboard (Blazor Server)
-- **🔐 Авторизация через Telegram**: Безопасный вход с использованием Telegram Login Widget (HMAC-SHA256 валидация).
-- **📱 Telegram Mini App Dashboard**: Мобильная версия dashboard открывается прямо из Telegram, проверяет WebApp `initData` на сервере и использует те же права owner/co-GM, что и обычный Web Dashboard. Mini App ждёт данные Telegram при старте и автоматически обновляет состояние входа после внешнего Telegram Login, включая возврат на страницу `/login`.
-- **📝 Удобное редактирование**: Веб-интерфейс для детального редактирования сессий, изменения дат, названий и статусов.
-- **🤝 Co-GM и делегирование**: Owner группы назначает помощников по Telegram ID, а co-GM получает доступ к управлению расписанием в Telegram и Web Dashboard.
-- **📋 Шаблоны кампаний**: Owner и co-GM управляют типовыми параметрами кампаний в отдельной вкладке `Шаблоны`, а на странице группы запускают новый повторяющийся batch из выбранного шаблона.
-- **🧩 Bulk-операции для Batch Sessions**: ГМ может обновить общий title/link, перенести всю пачку на фиксированный шаг и клонировать batch на следующую неделю или месяц.
-- **🔕 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.
-- **🕒 Управление временем**: UI адаптирован под московское время (UTC+3), в то время как база данных работает в UTC.
+- **🔐 Авторизация через Telegram**: Telegram Login Widget с HMAC-SHA256 валидацией.
+- **📱 Telegram Mini App Dashboard**: Мобильная панель открывается из Telegram, проверяет `initData` на сервере, учитывает safe-area телефона и верхнюю панель Telegram.
+- **✏️ Редактирование**: Детальное изменение дат, названий и статусов сессий.
+- **🤝 Co-GM и делегирование**: Owner назначает помощников по Telegram ID; co-GM управляет расписанием, но **не может назначать других co-GM**.
+- **🌍 Публичные страницы клубов**: Owner и co-GM включают read-only страницу `/club/{slug}` и отдельные ссылки `/s/{sessionId}` только для опубликованных сессий; состав игроков и приватные join-ссылки не показываются.
+- **🧑‍🏫 Публичные профили мастеров**: мастер управляет профилем из `/profile`, публикует описание на `/gm/{slug}`, а публичные клубы, игры и каталог ссылаются на профиль без раскрытия platform identifiers.
+- **📚 Портфолио завершённых приключений**: Owner и co-GM собирают завершённые сессии в портфолио-игры на странице `/group/{id}/portfolio`, привязывают ссылки на прошедшие сессии и публикуют публичную страницу `/portfolio/{slug}` с обложкой, описанием, системой/форматом и составом мастеров.
+- **⭐ Модерируемые отзывы игроков**: участники прошедших сессий могут оставить отзыв на `/portfolio/{slug}/review` с явным согласием на публикацию; мастера модерируют отзывы (`Approved`/`Rejected`/`Hidden`) в редакторе портфолио, и только одобренные отзывы видны публичной странице.
+- **🖼 Обложки портфолио**: мастера загружают JPG/PNG/WEBP-обложки в редакторе портфолио; файлы сохраняются в Docker volume `portfolio_covers` и обслуживаются по пути `/portfolio-covers/{storageKey}`; конфигурация пути — `PortfolioCovers__StoragePath` в `compose.yaml`.
+- **📋 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 platform message расписания через `IPlatformMessenger`.

 ## 🚀 Быстрый старт (Docker Compose)
 
-Проект использует Docker Compose для одновременного запуска базы данных, бота и веб-интерфейса.
-
-### 1. Подготовка
-Убедитесь, что у вас установлены **Docker** и **Docker Compose**.
-
-### 2. Настройка окружения
-Скопируйте файл-шаблон и заполните его значениями:
+**Требования:** Docker и Docker Compose.
 
+### 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.
-# Найти его можно в информации о боте у @BotFather. 
-# Используется для работы виджета авторизации (Telegram Login Widget).
+# Токен Discord application bot
+DISCORD_BOT_TOKEN=ваш_discord_токен_здесь
+
+# Discord OAuth (для Web Dashboard)
+DISCORD_CLIENT_ID=ваш_discord_client_id_здесь
+DISCORD_CLIENT_SECRET=ваш_discord_client_secret_здесь
+DISCORD_REDIRECT_URI=https://your-domain.example/auth/discord/callback
+
+# Имя бота без @ (для Telegram Login Widget)
 TELEGRAM_BOT_USERNAME=ваше_имя_бота_здесь
 
-# HTTPS URL Mini App dashboard, например: https://your-domain.example/miniapp.
-# Используется кнопкой меню Telegram и кнопкой /start.
+# HTTPS URL Mini App, например https://your-domain.example/miniapp
 TELEGRAM_MINI_APP_URL=https://your-domain.example/miniapp
 
-# Пароль для базы данных PostgreSQL
 POSTGRES_PASSWORD=ваш_надежный_пароль
-
-# Локальный порт веб-интерфейса GM-Relay
 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`.
 
-Для Telegram Mini App настройте в @BotFather домен Web Dashboard и menu button на URL из `TELEGRAM_MINI_APP_URL`. Бот также показывает кнопку `Открыть dashboard` в ответе на `/start`, если переменная задана.
-
-### 3. Запуск
-Выполните команду:
+### 2. Запуск
 ```bash
 docker compose up -d
 ```
-Инфраструктура автоматически:
-- Создаст локальную Docker-сеть и volume PostgreSQL, если их ещё нет.
-- Поднимет PostgreSQL, доступный для контейнеров как `db:5432`.
-- Запустит бота (применив миграции БД).
-- Запустит веб-интерфейс на `http://localhost:8080` или другом порту из `GMRELAY_WEB_PORT`.
+
+**Автоматически выполняется:**
+- создание Docker-сети и volume PostgreSQL;
+- подъём PostgreSQL (`db:5432`);
+- запуск бота с плавной миграцией (DbUp);
+- запуск Discord Gateway worker на NetCord (healthcheck на `:8082`);
+- запуск веб-приложения с подключением к БД и Telegram API.
+
+### 3. Первоначальная настройка
+1. Напишите боту `/start`.
+2. Создайте группу через `/newgroup`.
+3. Откройте Mini App или Web Dashboard для расширенного управления.
+4. Для Discord пригласите application bot на сервер с правами `bot` и `applications.commands`. Скопируйте `DISCORD_BOT_TOKEN` в `.env`; `DISCORD_CLIENT_ID`, `DISCORD_CLIENT_SECRET` и `DISCORD_REDIRECT_URI` нужны только для входа в Web Dashboard через Discord.
+5. Перезапустите Docker Compose (`docker compose up -d`), а затем в Discord создайте сессию через `/newsession` или опубликуйте расписание через `/listsessions`; игроки записываются и выходят кнопками в опубликованном сообщении.
+
+## 📚 Портфолио завершённых приключений
+
+Начиная с **v3.6.0** ГМы могут публиковать завершённые кампании в виде постоянных портфолио-страниц с обложкой, описанием, системой/форматом, составом мастеров и модерируемыми отзывами игроков.
+
+### Возможности
+
+- **Управление портфолио** — в `/group/{id}/portfolio` владелец и co-GM создают портфолио-игры из прошедших сессий, выбирают мастеров, заполняют описание, загружают обложку и публикуют по `public_slug`.
+- **Публичная страница `/portfolio/{slug}`** — read-only карточка приключения с обложкой, описанием, составом мастеров (только публичные профили) и одобренными отзывами.
+- **Отзывы участников** — на `/portfolio/{slug}/review` аутентифицированные игроки, чьи идентификаторы участвовали в одной из привязанных сессий без пометки GM, отправляют отзыв с явным согласием на публикацию; один отзыв на игрока, повторная отправка запрещена.
+- **Модерация отзывов** — на странице редактора портфолио владелец/co-GM видит очередь `Pending` и переводит отзывы в `Approved`, `Rejected` или `Hidden`; только `Approved` отзывы попадают в публичную выдачу.
+- **Публикация под требования** — портфолио-игра публикуется только при заполненном slug, описании, обложке, минимум одной завершённой сессии и хотя бы одном мастере группы.
+
+### Хранение обложек
+
+Загруженные обложки хранятся в Docker volume `portfolio_covers` (по умолчанию имя `gmrelay_portfolio_covers`), обслуживаются веб-приложением по пути `/portfolio-covers/{storageKey}` с кешированием `Cache-Control: public, max-age=31536000, immutable`.
+
+В `.env` можно переопределить имя volume:
+
+```env
+PORTFOLIO_COVERS_VOLUME_NAME=gmrelay_portfolio_covers
+```
+
+В `compose.yaml` это значение пробрасывается в сервис `web` через `volumes.portfolio_covers.name`; путь к каталогу внутри контейнера — `/app/portfolio-covers` (настраивается через `PortfolioCovers__StoragePath`).
+
+Хранилище инкапсулировано интерфейсом `IPortfolioCoverStorage` с реализацией `LocalPortfolioCoverStorage` (файловая система), что оставляет границу для замены на S3-совместимое хранилище без изменения кода портфолио-сервисов.
+
+## 💾 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
+```

-## ⚙️ Настройка бота в Telegram
+## 🗂 Структура репозитория
 
-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]
-> Owner группы определяется по первому человеку, который создал сессию в этой группе. Owner может назначать co-GM в Web Dashboard; owner и co-GM могут управлять сессиями через кнопки бота и веб-интерфейс.

-## 📝 Инструкция для Мастера
+## 👨‍💻 Для разработчиков
 
-### 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
-Мест: 4
-Ссылка: https://discord.gg/invite-link
-```
-
-Строка `Мест:` необязательна. Если она указана, игроки сверх лимита попадут в лист ожидания, а ГМ сможет повысить первого ожидающего через кнопку в Telegram или Web Dashboard.
-
-Для регулярной кампании можно не перечислять все даты вручную. Укажите одну строку `Время:`, количество игр и интервал в днях:
-
-```text
-/newsession
-Название: Kingmaker
-Время: 30.04.2026 19:30
-Игр: 6
-Интервал: 7
-Мест: 5
-Ссылка: https://discord.gg/invite-link
-```
-
-Бот создаст 6 игр с недельным шагом. Вместо `Игр:` также принимается `Сессий:` или `Повторов:`, вместо `Интервал:` — `Шаг:`.
-
-Игрок может самостоятельно снять запись кнопкой `🚪 Выйти` в сообщении расписания. Если он был в основном составе и в листе ожидания есть игроки, бот автоматически переводит первого ожидающего в основной состав и обновляет сообщение пачки.
-
-### Делегирование управления
-На странице группы Web Dashboard показывает owner и список co-GM. Owner может добавить помощника по Telegram ID, имени и username, а также снять роль co-GM. Назначенный co-GM видит группу в панели управления и может редактировать сессии, управлять batch-операциями, очередью, переносами и удалением игр, но не может назначать других co-GM.
-
-### Перенос сессии голосованием
-Owner или co-GM нажимает кнопку `⏰ Перенести` у нужной сессии и отправляет в чат 2-3 варианта нового времени вместе с дедлайном:
-
-```text
-25.04.2026 19:30
-26.04.2026 18:00
-Дедлайн: 25.04.2026 12:00
-```
-
-Дедлайн должен быть в будущем и раньше первого предложенного времени. Участники выбирают один вариант кнопкой в Telegram, могут изменить голос до дедлайна и видят текущие результаты в сообщении голосования. По дедлайну бот выбирает вариант с наибольшим числом голосов, переносит сессию, сбрасывает RSVP и обновляет batch-сообщение. Если голосов нет или есть ничья, перенос отклоняется, а время сессии остаётся прежним.
-
-### Шаблоны и bulk-операции в Web Dashboard
-Вкладка `Шаблоны` в левом меню вынесена отдельно от страницы группы. Owner и co-GM выбирают группу, сохраняют шаблон кампании с названием, ссылкой, количеством игр, интервалом, лимитом мест и режимом уведомлений, а также удаляют устаревшие шаблоны.
-
-На странице группы Web Dashboard показывает только применение сохранённых шаблонов и отдельный блок для каждой пачки игр. Owner и co-GM могут:
-- создать новый batch из шаблона, выбрав только первую дату расписания;
-- обновить общий `title` и `link` сразу у всех сессий batch;
-- выбрать режим уведомлений: дублировать важные сообщения игрокам в личку или оставить только групповые уведомления;
-- перенести пачку, задав новую первую дату и фиксированный шаг между играми в днях;
-- клонировать batch на следующую неделю или следующий календарный месяц.
-
-После создания из шаблона или клонирования появляется новая пачка с новым Telegram-сообщением и пустым составом игроков. После редактирования или переноса исходное Telegram-сообщение расписания перерисовывается.
-
-Если включён режим `В группе и в личку`, бот дополнительно отправляет игрокам персональные сообщения о RSVP за 24 часа, напоминание за 1 час, ссылку перед стартом, отмену и перенос. Если Telegram не позволяет написать игроку в ЛС, бот логирует ошибку и продолжает отправку остальным участникам.
-
-### Telegram Mini App Dashboard
-Owner и co-GM могут открыть мобильный dashboard прямо из Telegram через кнопку меню бота или кнопку `Открыть dashboard` после `/start`. Страница `/miniapp` получает `Telegram.WebApp.initData`, отправляет его на серверный endpoint `/auth/telegram-webapp`, проходит HMAC-проверку токеном бота и выдаёт обычную cookie-сессию dashboard.
-
-После входа Mini App использует те же страницы, что и Web Dashboard: список групп, карточки сессий, редактирование игры, повышение игрока из листа ожидания, применение шаблонов и bulk-операции batch. Доступ к чужим группам не появляется: все данные по-прежнему фильтруются через `AuthorizedSessionService` по роли owner/co-GM.
-
-### Другие команды
-- `/listsessions` — Показать список всех актуальных игр в этой группе.
-- `⏰ Перенести` в сообщении расписания — Запустить голосование по 2-3 вариантам нового времени.
-- `/deletesession` — Удалить сессию.
-- `/exportcalendar` — Получить `.ics` файл с играми.
-- `/help` — Справка по формату.

-## 🏗 Разработка и запуск локально (.NET Aspire)
-
-Для локальной разработки проще всего использовать .NET Aspire:
-
-1. Установите [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0) и workload Aspire.
-2. Откройте решение `GM-Relay.slnx`.
-3. Установите переменные окружения (или user secrets) для `GmRelay.AppHost`.
-4. Запустите проект `GmRelay.AppHost`. Aspire Dashboard запустится автоматически, предоставляя удобный мониторинг БД, бота и веб-интерфейса.
-
-> [!NOTE]
-> При использовании **Dapper** в режиме Native AOT, все SQL-запросы используют строго типизированные DTO. Динамические типы (`dynamic`) не поддерживаются.
+- **Архитектура**: проект следует Vertical Slice с явным DI. Подробности — в [ADR-001](docs/adr/0001-use-vertical-slice-native-aot-and-aspire.md) и [ADR-002](docs/adr/002-platform-neutral-batch-rendering.md).
+- **Добавление обработчика**: из-за Native AOT все DI-регистрации выполняются вручную в `src/GmRelay.Bot/Program.cs` (assembly scanning не используется).
+- **Миграции**: SQL-скрипты добавляются как embedded resources в `src/GmRelay.Bot/Migrations/` и применяются автоматически при старте бота через DbUp.
+- **Тесты**: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --verbosity normal`
+- **Сборка**: `dotnet build`

+# 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 ──► Discord embeds + buttons
+```
+
+### 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.DiscordBot.Rendering` |
+| `BatchMessageEditor` | `GmRelay.Shared.Rendering` | `GmRelay.Bot` + `GmRelay.Web` |
+
+## Consequences
+
+### Positive
+
+- `GmRelay.Shared` больше не зависит от `Telegram.Bot`. Чистый platform-agnostic проект.
+- Discord renderer lives in `GmRelay.DiscordBot`, so NetCord stays out of `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.

+# ADR 003: Discord Integration Architecture
+
+## Status
+
+**Accepted** — implemented in v2.6.0 (PR #87, issue #30).
+
+## Context
+
+После Telegram-бота требовалась поддержка Discord для кросс-платформенных групп. Нужно было выбрать:
+1. Библиотеку для Discord API (NetCord vs DSharpPlus vs Discord.NET).
+2. Модель runtime (отдельный процесс vs тот же Worker).
+3. Способ обработки интеракций (Gateway events vs HTTP interactions).
+
+## Decision
+
+### 1. NetCord (не DSharpPlus, не Discord.NET)
+
+- **NetCord** — лёгкий, AOT-compatible, minimal dependencies.
+- **DSharpPlus** — слишком тяжёлый, много зависимостей, reflection-heavy.
+- **Discord.NET** — несовместим с Native AOT (heavy reflection, dynamic IL).
+
+### 2. Gateway Events внутри GmRelay.Bot
+
+- Discord Gateway worker живёт **внутри** `GmRelay.Bot` (тот же Worker Service), а не как отдельный проект.
+- Это упрощает DI, shared DB connection, shared `IPlatformMessenger`.
+- Для масштабирования можно вынести в отдельный контейнер позже.
+
+### 3. Slash-команды через NetCord ApplicationCommandService
+
+- Регистрация глобальных slash-команд (`/newsession`, `/listsessions`) через `ApplicationCommandService`.
+- Команды мапятся на vertical slice handlers через `DiscordSessionInteractionModule`.
+
+### 4. Ephemeral Replies
+
+- Все кнопки (Join/Leave/RSVP) отвечают ephemeral (`MessageFlags.Ephemeral`).
+- Schedule message редактируется через `DiscordPlatformMessenger` (реализация `IPlatformMessenger`).
+
+## Consequences
+
+### Positive
+
+- Один бинарник для Telegram + Discord.
+- Shared DI, shared DB pool, shared domain logic.
+- Native AOT совместимость.
+
+### Negative
+
+- Gateway connection требует persistent WebSocket — при разрыве происходит reconnect.
+- Discord rate limits агрессивнее Telegram — нужен backoff.
+
+## Related
+
+- Issue #30 — reschedule voting (кнопки + дедлайн).
+- Issue #31 — scheduler notifications через `IPlatformMessenger`.
+- Issue #32 — compose wiring + healthcheck.

+The portfolio subsystem lets GMs curate completed adventures from past sessions, publish a public detail page, and collect moderated player reviews. The cover files live in a persistent volume via the `IPortfolioCoverStorage` boundary; the public schema and contracts are isolated inside `GmRelay.Web.Services.Portfolio` so a future S3-compatible storage adapter can replace `LocalPortfolioCoverStorage` without touching the data layer.

+### Cover storage boundary
+
+- `IPortfolioCoverStorage` is registered as a DI singleton in `GmRelay.Web`.
+- The current implementation `LocalPortfolioCoverStorage` writes under `PortfolioCovers:StoragePath` (default `/app/portfolio-covers`) and is mounted as the Docker volume `portfolio_covers` (configurable via `PORTFOLIO_COVERS_VOLUME_NAME` in `.env`).
+- Static files are served by the web container at `/portfolio-covers/{storageKey}` with `Cache-Control: public, max-age=31536000, immutable`.
+- Replacing the local filesystem with S3-compatible object storage is a contract-only change: implement `IPortfolioCoverStorage` with the same `SaveAsync` / `GetPublicPath` / `DeleteIfExistsAsync` surface and swap the DI registration in `PortfolioCoverStorageExtensions.AddPortfolioCoverStorage`.

-# 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.

+# Game Catalog and One-Shot Showcase — Design Spec
+
+> Issue #39: feat: добавить каталог игр и витрину ваншотов
+
+---
+
+## Goal
+Build a public `/showcase` page that aggregates published sessions from all clubs into a filterable catalog. Users can browse games by system, format, date, and availability. GM controls whether direct registration from the catalog is allowed. The catalog respects existing seat limits and waitlist logic.
+
+---
+
+## Architecture
+Extend the existing public-pages infrastructure (V026) with new session metadata fields, a cross-group query layer in `ISessionStore`, and new Razor pages in `GmRelay.Web`. Bot flows (Telegram + Discord) are updated to collect the new fields during session creation. Fuzzy matching on game system names is performed client-side in the bot UI.
+
+---
+
+## Tech Stack
+- .NET 10, Blazor Server, Dapper.AOT, Npgsql
+- Existing: `PublicLayout`, `ISessionStore`, `SessionService`, `SessionCapacityRules`
+- New: `GameSystem` enum, `ShowcaseFilter` record, `ShowcaseSessionDto`
+
+---
+
+## Data Model
+
+### New Fields on `sessions` (Migration V027)
+
+| Column | Type | Constraints | Description |
+|---|---|---|---|
+| `is_one_shot` | `BOOLEAN` | `NOT NULL DEFAULT false` | One-shot or campaign |
+| `system` | `VARCHAR(50)` | nullable | Game system name (enum value or custom) |
+| `description` | `TEXT` | nullable | Short description for card |
+| `cover_image_url` | `TEXT` | nullable | Cover image URL |
+| `duration_minutes` | `INTEGER` | nullable | Duration in minutes |
+| `format` | `VARCHAR(20)` | `CHECK (format IN ('Online','Offline','Hybrid'))`, nullable | Session format |
+| `allow_direct_registration` | `BOOLEAN` | `NOT NULL DEFAULT false` | Allow direct registration from showcase |
+
+### `GameSystem` Enum
+
+```csharp
+public enum GameSystem
+{
+    Dnd5e, Pathfinder2e, CallOfCthulhu7e, Shadowdark,
+    OldSchoolEssentials, Dragonbane, BladesInTheDark,
+    Daggerheart, CyberpunkRed, Mothership, AlienRpg,
+    WarhammerFantasy, VampireMasquerade5e, StarWarsFfg,
+    Genesys, SavageWorlds, GURPS, Fate, DungeonWorld,
+    Ironsworn, Other
+}
+```
+
+Stored as `VARCHAR(50)` in DB (not native enum) to allow future extension without migration.
+
+### DTOs
+
+```csharp
+public sealed record ShowcaseSessionDto(
+    Guid Id,
+    Guid GroupId,
+    string GroupName,
+    string? GroupSlug,
+    string Title,
+    DateTime ScheduledAt,
+    string Status,
+    string? System,
+    bool IsOneShot,
+    string? Format,
+    int? DurationMinutes,
+    string? CoverImageUrl,
+    int? MaxPlayers,
+    int ActivePlayerCount,
+    int WaitlistedPlayerCount,
+    bool AllowDirectRegistration);
+
+public sealed record ShowcaseFilter(
+    DateFilter Date = DateFilter.All,
+    SeatFilter Seats = SeatFilter.Any,
+    GameSystem? System = null,
+    bool? IsOneShot = null,
+    string? Format = null);
+
+public enum DateFilter { Today, Tomorrow, ThisWeek, All }
+public enum SeatFilter { Available, Waitlist, Any }
+```
+
+---
+
+## UI Design
+
+### `/showcase` — Catalog Page
+
+**Layout:**
+- Hero with title "Каталог игр"
+- Sticky filter bar (horizontal on desktop, collapsible on mobile)
+- Responsive grid of session cards (1 col mobile, 2 col tablet, 3 col desktop)
+- Pagination (page + pageSize = 12)
+
+**Filters:**
+- Date: "Сегодня" | "Завтра" | "На неделю" | "Все"
+- Seats: "Есть места" | "Waitlist" | "Любое"
+- System: dropdown with all `GameSystem` values
+- Type: "Ваншот" | "Кампания" | "Любое"
+- Format: "Онлайн" | "Офлайн" | "Гибрид" | "Любое"
+
+**Card Design:**
+- Cover image (fallback: colored placeholder with initials)
+- Title
+- System badge
+- Date + time (MSK)
+- Duration (e.g. "3 часа")
+- Format badge
+- Seats indicator: "5/6 мест" | "Waitlist (3)" | "Мест нет"
+- Club name (link to `/club/{slug}`)
+- Buttons: "Подробнее" → `/s/{id}`, "Записаться" (if `AllowDirectRegistration`)
+
+### `/s/{id}` — Public Session Detail (Updated)
+
+New fields added to existing page:
+- Cover image (full-width hero)
+- System badge
+- Description block
+- Duration + format
+- GM contact (always visible: Telegram username or Discord tag)
+- If `allow_direct_registration`:
+  - "Записаться" button → Telegram Mini App deeplink or Discord OAuth
+  - Direct registration into `session_participants` via `SessionCapacityRules`
+
+---
+
+## Backend
+
+### ISessionStore Methods
+
+```csharp
+Task<IReadOnlyList<ShowcaseSessionDto>> GetShowcaseSessionsAsync(
+    ShowcaseFilter filter, int page, int pageSize);
+
+Task<ShowcaseSessionDto?> GetShowcaseSessionAsync(Guid sessionId);
+
+Task<bool> RegisterFromShowcaseAsync(Guid sessionId, PlatformUser user);
+```
+
+`GetShowcaseSessionsAsync` query:
+- Cross-group (all clubs with `public_schedule_enabled = true`)
+- Only `is_public = true` sessions
+- `scheduled_at > now() - interval '4 hours'`
+- `status <> 'Cancelled'`
+- Apply filters in SQL WHERE clause
+- Order by `scheduled_at ASC`
+- Offset/limit pagination
+
+`RegisterFromShowcaseAsync`:
+- Check `allow_direct_registration = true`
+- Load session with `FOR UPDATE`
+- Count active + waitlisted participants
+- Use `SessionCapacityRules.DecideJoinStatus`
+- Insert participant with appropriate `registration_status`
+- Return true on success, false if full and no waitlist allowed
+
+---
+
+## Bot Integration
+
+### Telegram Bot
+
+During `CreateSessionCommand` flow, after title/link/time input:
+1. "Выберите систему:" inline keyboard with `GameSystem` values + "Другое"
+2. If text input instead of button: fuzzy match against display names (Levenshtein/Contains/StartsWith)
+3. "Описание игры (краткое):" — text input, optional (skip button)
+4. "Формат:" inline keyboard — "Онлайн" | "Офлайн" | "Гибрид"
+5. "Продолжительность (в часах):" — int input, optional
+6. "Обложка (URL или пропустить):" — text input, optional
+
+During `/publish` flow:
+- "Разрешить прямую запись из каталога?" — yes/no toggle (default: no)
+
+### Discord Bot
+
+Same flow adapted for Discord interactions:
+- Slash command options or button menus for system/format
+- Modal input for description, duration, cover URL
+- Fuzzy matching on free-text system input
+
+---
+
+## Migration V027
+
+```sql
+ALTER TABLE sessions
+    ADD COLUMN is_one_shot BOOLEAN NOT NULL DEFAULT false,
+    ADD COLUMN system VARCHAR(50),
+    ADD COLUMN description TEXT,
+    ADD COLUMN cover_image_url TEXT,
+    ADD COLUMN duration_minutes INTEGER,
+    ADD COLUMN format VARCHAR(20) CHECK (format IN ('Online','Offline','Hybrid')),
+    ADD COLUMN allow_direct_registration BOOLEAN NOT NULL DEFAULT false;
+
+CREATE INDEX ix_sessions_showcase
+    ON sessions (scheduled_at, system, is_one_shot, format)
+    WHERE is_public = true AND status <> 'Cancelled';
+```
+
+---
+
+## Testing Strategy
+
+1. **Unit tests:** `SessionCapacityRules` with showcase registration scenarios
+2. **Integration tests:** `GetShowcaseSessionsAsync` with each filter combination
+3. **UI tests:** `Showcase.razor` rendering with/without cover images, filters applied
+4. **Bot tests:** Fuzzy matching algorithm for `GameSystem` resolution
+
+---
+
+## Version Bump
+
+Issue label: `type:feature` → **minor bump**
+Current: `3.3.0` → Next: `3.4.0`
+
+Files to sync:
+- `Directory.Build.props`
+- `compose.yaml` (bot, discord, web image tags)
+- `.gitea/workflows/deploy.yml` (`VERSION` env)
+- `src/GmRelay.Web/Components/Layout/NavMenu.razor`
+
+---
+
+## Acceptance Criteria (from Issue #39)
+
+- [ ] User can find a published game without accessing a private dashboard
+- [ ] Registration does not bypass existing seat/waitlist limits
+- [ ] Owner/co-GM controls what appears in the showcase via `is_public` + `allow_direct_registration`
+- [ ] Filters work: date, seats, system, type, format
+- [ ] GM contact is always visible on public session detail
+- [ ] Direct registration respects `SessionCapacityRules`

+# Completed Game Portfolio - Design Spec
+
+> Issue #108: feat: добавить портфолио прошедших игр в витрину мастера
+
+---
+
+## Goal
+
+Add a public portfolio of completed tabletop adventures. A club owner or co-GM can group one or more completed sessions into an adventure card, publish it in selected GM profiles, optionally show it on a public club page, upload a cover image, and moderate player reviews. The existing `/showcase` catalog remains focused on recruitment for upcoming games.
+
+---
+
+## Product Decisions
+
+- A portfolio item is an independent adventure entity, not a flag on one session.
+- One adventure can reference multiple completed sessions from the same club.
+- Reviews are submitted by authenticated players, not entered manually by a GM.
+- A player can review an adventure after being actively registered as a non-GM participant for at least one linked completed session. Waitlisted players are not eligible.
+- Each player can submit one review per adventure.
+- A review is public only after the player explicitly consents to publication and a club owner or co-GM approves it.
+- Public reviews show a display-name snapshot captured at submission time. They never expose platform IDs or account links.
+- Adventure visibility in a public GM profile does not depend on club-page visibility.
+- The public club page shows its portfolio block only when that club page is enabled.
+- Club owners and co-GMs create, edit, publish, and moderate portfolio items. They select one or more GMs whose public profiles display the adventure.
+- Creation is available from the club page and through a quick action from a completed session.
+- Every published adventure has a dedicated public page at `/portfolio/{slug}`.
+- Cover images are uploaded to application-managed storage. The first implementation uses a persistent Docker volume behind a replaceable storage interface so an S3-compatible implementation can be added later without changing pages or database tables.
+
+---
+
+## Architecture
+
+Add a bounded portfolio vertical slice to `GmRelay.Web` and a schema migration in `GmRelay.Bot`. The portfolio tables reference the existing `game_groups`, `players`, and `sessions` tables but do not change the recruitment catalog query or its future-session filters.
+
+Keep portfolio persistence separate from the already large scheduling store. `IPortfolioStore` and `PortfolioService` own portfolio reads, writes, and review submission. `AuthorizedPortfolioService` wraps protected management operations and reuses `ISessionStore.IsGroupManagerAsync` plus the existing current-user identity model for owner/co-GM authorization. Public Razor pages inject `IPortfolioStore` directly for sanitized reads.
+
+Cover storage is isolated behind `IPortfolioCoverStorage`. Pages and services work with generated storage keys and public paths rather than physical file locations. The local implementation stores files in a persistent mounted directory and serves them through a dedicated request path. A future S3 implementation can generate equivalent public paths or signed delivery URLs while preserving the same service contract and database fields.
+
+---
+
+## Data Model
+

+
+Create `src/GmRelay.Bot/Migrations/V029__add_completed_game_portfolios_and_reviews.sql`.

+| `created_at` | `TIMESTAMPTZ` | not null, default now | Audit timestamp |
+| `updated_at` | `TIMESTAMPTZ` | not null, default now | Audit timestamp |
+
+Constraints and indexes:
+
+```sql
+CHECK (NOT is_public OR (
+    public_slug IS NOT NULL
+    AND description IS NOT NULL
+    AND cover_storage_key IS NOT NULL
+    AND published_at IS NOT NULL
+))
+```
+
+- Unique index on `lower(public_slug)` when `public_slug IS NOT NULL`.
+- Index on `(group_id, completed_at DESC)`.
+- Partial public index on `(completed_at DESC)` where `is_public = true`.
+
+Application validation additionally requires at least one linked session, every linked session to be completed with `scheduled_at < now()`, and at least one linked GM before publishing because those requirements span child tables. Publishing locks the parent card, validates both required link sets, then sets `is_public = true` and `published_at = COALESCE(published_at, now())` so `published_at` remains the first-publication timestamp. Link replacement locks the parent card and unpublishes it before replacing required links.
+
+Immediate statement triggers acquire one transaction-level PostgreSQL advisory lock, `pg_advisory_xact_lock(20260530, 108)`, before any invariant-affecting rows are changed: publication transitions and deletes, required-link edits, session deletes and scheduled-date changes, and parent deletes that can cascade into required links. Deferred database constraint triggers validate the same invariant at transaction commit after a card transitions to public, a session link is inserted, deleted, moved, or repointed, or a required master link is deleted or moved. They raise a check-violation error if a published card would commit without both required link sets or with any linked session where `scheduled_at >= now()`. Portfolio and schedule mutations are low volume, so this intentionally global lock establishes one advisory-lock then row-lock protocol, prevents write-skew under the application default `READ COMMITTED` isolation level, and avoids multi-card, card/advisory, and session/advisory deadlocks. PostgreSQL keeps a stale snapshot after waiting under `REPEATABLE READ` or `SERIALIZABLE`, so the guard rejects every triggered portfolio write at those levels; callers must use `READ COMMITTED` for portfolio mutations.
+
+A deferred `sessions.scheduled_at` trigger atomically unpublishes linked public cards when a completed session is finally rescheduled into the future, preserving the first `published_at`. Because deferred row triggers retain their event-time `NEW`, the trigger re-reads the final `sessions.scheduled_at` before acting. It rejects final-future reschedules outside `READ COMMITTED` with `0A000`, because the unpublish pass requires fresh statement snapshots. Under `READ COMMITTED`, it takes row locks for all cards linked to any final-future session in `portfolio_games.id` order, including committed drafts. It then re-acquires the publication advisory lock and unpublishes matching public cards in a guarded update with a fresh statement snapshot. Including drafts prevents a concurrent draft-to-public publication from validating against the pre-reschedule session snapshot and committing afterward. Session mutation paths use advisory-lock then `sessions` then linked `portfolio_games`; normal session-deletion handlers explicitly acquire the mutation lock, lock the target session row, unpublish linked cards in the same transaction, and only then delete the session. The link foreign keys retain `ON DELETE CASCADE`; when the card itself or its owning club is deleted at `READ COMMITTED`, deferred validation sees no surviving published card and remains harmless.
+
+### `portfolio_game_sessions`
+
+| Column | Type | Constraints | Description |
+|---|---|---|---|
+| `portfolio_game_id` | `UUID` | not null, FK to `portfolio_games(id)` with cascade delete | Adventure |
+| `session_id` | `UUID` | not null, unique, FK to `sessions(id)` with cascade delete | Linked completed session |
+
+Primary key: `(portfolio_game_id, session_id)`.
+
+The application accepts only sessions from the adventure's club with `scheduled_at < now()` and rejects cross-club links. The deferred database guard enforces the completed-session condition for every linked session before a public card can commit. A session belongs to at most one portfolio adventure.
+
+### `portfolio_game_masters`

+    Task DeleteIfExistsAsync(
+        string storageKey,
+        CancellationToken cancellationToken = default);
+
+    string GetPublicPath(string storageKey);
+}
+```
+
+`PortfolioCoverUploadResult` carries the generated storage key and normalized content type.
+
+### Local Implementation
+
+- Store covers below a configured `PortfolioCovers:StoragePath`.
+- Mount that path from a dedicated Docker volume, `portfolio_covers`.
+- Serve files through a dedicated `/portfolio-covers/{storageKey}` route.
+- Generate random names. Never use the uploaded filename as the storage key.
+- Accept `image/jpeg`, `image/png`, and `image/webp`.
+- Limit uploads to 5 MiB.
+- Validate file signatures server-side before writing the final file.
+- Write to a temporary file, validate, then atomically move into place.
+- On successful replacement, delete the old file.
+- On database failure after upload, delete the newly uploaded file.
+- Deleting an adventure deletes its current cover after successful database deletion.
+
+The storage key remains provider-neutral. A future S3-compatible implementation can replace the local service registration and use the same stored key.
+
+---
+
+## Service Contracts
+
+Add sanitized DTOs to `IPortfolioStore`. Public DTOs must not expose player IDs, group IDs, session IDs, platform identifiers, moderator IDs, physical storage paths, or join links.
+
+Representative contracts:
+
+```csharp
+public sealed record PublicPortfolioGame(
+    string Slug,
+    string Title,
+    string Description,
+    string CoverPath,
+    string? System,
+    string? Format,
+    DateTime CompletedAt,
+    string? ClubName,
+    string? ClubSlug,
+    IReadOnlyList<PublicPortfolioMaster> Masters,
+    IReadOnlyList<PublicPortfolioReview> Reviews);
+
+public sealed record PublicPortfolioMaster(string Slug, string DisplayName);
+
+public sealed record PublicPortfolioReview(
+    string AuthorDisplayName,
+    string Body,
+    DateTime CreatedAt);
+```
+
+Protected DTOs may carry IDs needed for editing and moderation.
+
+### Public Reads
+
+- Load one public adventure by slug for `/portfolio/{slug}`.
+- Load public adventures for a public GM profile regardless of club-page visibility.
+- Load public adventures for a public club page only when the club page is enabled.
+- Return only reviews with explicit consent and `Approved` moderation state.
+
+### Protected Management
+
+Through `AuthorizedPortfolioService`:
+
+- Load draft and published adventure cards for a managed club.
+- Load eligible completed sessions for a managed club.
+- Create a draft, optionally preselecting one completed session from the quick action.
+- Update title, slug, description, system, format, linked sessions, and displayed GMs.
+- Upload and replace the cover.
+- Publish or unpublish a card.
+- Load pending and historical reviews for moderation.
+- Approve, reject, or hide a review.
+
+All management operations require the current user to be an owner or co-GM of the owning club.
+
+### Review Submission
+
+An authenticated user can submit a review from `/portfolio/{slug}` only when:
+
+- The adventure is public.
+- The user explicitly checks publication consent.
+- The user is registered in `session_participants` as a non-GM participant with `registration_status = 'Active'` for at least one linked session.
+- The linked session is in the past.
+- The user has not submitted a review for this adventure before.
+
+The created review starts in `Pending`. The public page does not display it until moderation changes the status to `Approved`.
+
+---
+
+## User Interface
+
+### Protected Club Page
+
+Extend `GroupDetails.razor` with a completed-adventures section:
+
+- List draft and published portfolio cards.
+- Show title, publication state, linked-session count, displayed-GM count, and review moderation count.
+- Provide a create action, edit links, and a link to the club's completed-session list.
+
+### Completed Session Quick Action
+
+Add a protected `/group/{groupId}/completed` page that lists past sessions for a managed club. Extend that page and session history with an "Добавить в портфолио" action for a completed session that is not already linked. The action opens the adventure editor with that session preselected.
+
+### Adventure Editor
+
+Add a protected editor page:
+
+- Title and public slug.
+- Description.
+- System and format.
+- Multi-select of completed sessions from the same club.
+- Multi-select of displayed GMs.
+- Cover upload and replacement.
+- Draft save and publish/unpublish actions.
+- Review moderation list with approve, reject, and hide actions.
+
+The editor surfaces validation errors without publishing partial data.
+
+### Public GM Profile
+
+Extend `/gm/{slug}` with a "Проведённые приключения" portfolio section. Cards show cover, title, completion date, system, format, and a link to `/portfolio/{slug}`. This list is independent of club-page visibility.
+
+### Public Club Page
+
+Extend `/club/{slug}` with the same compact cards when the public club page is enabled.
+
+### Public Adventure Page
+
+Add `/portfolio/{slug}`:
+
+- Cover hero.
+- Title, description, completion date, system, and format.
+- Optional public club link.
+- Public links to selected GM profiles.
+- Approved reviews with display-name snapshots.
+- For an eligible authenticated player without an existing review: review form with text area and required publication-consent checkbox.
+- For an authenticated ineligible player or a player who already submitted: a short non-sensitive status message.
+- For an anonymous visitor: a sign-in prompt instead of the form.
+
+---
+
+## Privacy And Security
+
+- Public DTOs and rendered HTML never expose platform identifiers, player IDs, moderator IDs, linked session IDs, join links, or physical storage paths.
+- Cover upload validation uses content signatures, not only the browser-provided MIME type or filename.
+- Random storage keys prevent filename guessing and path traversal.
+- Review text is rendered as encoded text through normal Razor rendering.
+- Authorization is checked in the service layer for every management operation.
+- Eligibility is checked in the database-backed service when submitting a review; hiding the form is not treated as authorization.
+- The `/showcase` query keeps its current future-session condition and does not include completed adventures.
+
+---
+
+## Docker And Configuration
+
+Add:
+
+```yaml
+services:
+  discord:
+    depends_on:
+      bot:
+        condition: service_healthy
+
+  web:
+    depends_on:
+      bot:
+        condition: service_healthy
+    environment:
+      - "PortfolioCovers__StoragePath=/app/portfolio-covers"
+    volumes:
+      - portfolio_covers:/app/portfolio-covers
+
+volumes:
+  portfolio_covers:
+    name: ${PORTFOLIO_COVERS_VOLUME_NAME:-gmrelay_portfolio_covers}
+```
+
+Development configuration uses a local directory under the application content root or an explicitly configured path.
+
+The Web Docker image creates `/app/portfolio-covers` and assigns it to `$APP_UID` before switching to the non-root runtime user.
+
+The Telegram bot runs `DbMigrator` synchronously before its health endpoint becomes healthy. Docker Compose therefore starts Discord and Web only after the bot is healthy, using it as the schema-migration gate without duplicating migration ownership. The Aspire AppHost mirrors this readiness gate with database resource name `gmrelaydb`, matching application `ConnectionStrings:gmrelaydb`; it explicitly exposes the bot project resource's non-proxied port `8081` endpoint, attaches `.WithHttpHealthCheck("/health", endpointName: "health")`, and makes its `discord` and `web` project resources wait for both PostgreSQL and the healthy `bot` resource.
+
+---
+
+## Documentation
+
+Update:
+
+- `README.md` with public portfolio capability and local cover-storage configuration.
+- `docs/c4-system-context.md` with the portfolio slice and persistent cover volume.
+
+---
+
+## Testing Strategy
+
+Follow TDD for production changes.
+
+### Schema And Contracts
+
+- Migration source-contract tests assert the four new tables, format constraint, publication guard, case-insensitive slug uniqueness, group and GM-profile indexes, card-oriented pending-review index, immediate statement-level mutation locks, completed-session validator, deferred future-reschedule unpublish trigger, advisory-lock then session-row deletion locks, and the AppHost HTTP health gate.
+- PostgreSQL integration tests apply migrations V001 through V029 to `postgres:17-alpine` and cover direct invalid link removal, moved links, direct session/player cascades, explicit mutation-lock then session-lock then unpublish then session deletion, delete/reschedule mutation-gate ordering in both first-lock orders, rejection of publication when any linked session is future, automatic unpublish with preserved `published_at` after future reschedule, `past -> future -> past` final-state handling, required-link insertion and final-future reschedule mutation locks before rows, opposing-order batch future reschedules serialized before session rows, existing-link and new-link draft publication/reschedule races, both bounded publish/delete commit orders, concurrent removal of distinct required links without write-skew or deadlock under `READ COMMITTED`, rejection of equivalent `REPEATABLE READ` writes including both draft-delete versus publish commit orders and stale-snapshot final-future reschedules, and parent/card cascade deletion.
+- Public DTO reflection/source tests assert that private identifiers and physical storage paths are absent.
+- Existing showcase tests continue to assert the future-session catalog boundary.
+
+### Authorization And Eligibility
+
+- Owner and co-GM can manage a club adventure.
+- A manager of another club cannot manage it.
+- Only registered players from linked past sessions can submit.
+- A registered player can submit only once.
+- Consent is required.
+- A new review is pending and not public.
+- Only approved reviews are returned publicly.
+
+### Cover Storage
+
+- Accept valid JPEG, PNG, and WebP signatures.
+- Reject unsupported types, mismatched signatures, oversized files, and unsafe names.
+- Replacement deletes the old file only after the new file is stored.
+- Cleanup removes a newly uploaded file when persistence fails.
+
+### UI Source Contracts
+
+- Protected club and session-history pages expose management entry points.
+- Public GM and club pages render compact portfolio sections.
+- The public adventure page renders approved reviews and the conditional review form.
+- CSS defines responsive portfolio cards, cover hero, editor layout, and review states.
+
+### Regression
+
+- Run the full test suite.
+- Run `dotnet build`.
+- Run `dotnet format --verify-no-changes`.
+- Visually inspect the protected editor and public portfolio pages in the browser.
+
+---
+
+## Version Bump
+
+Issue label: `type:feature` -> minor bump.
+
+Current: `3.5.1` -> Next: `3.6.0`.
+
+Synchronize:
+
+- `Directory.Build.props`
+- `compose.yaml` (`bot`, `discord`, and `web` image tags)
+- `.gitea/workflows/deploy.yml` (`VERSION`)
+- `src/GmRelay.Web/Components/Layout/NavMenu.razor`
+
+---
+
+## Acceptance Criteria Mapping
+
+- [ ] A club owner or co-GM can publish a completed adventure with uploaded cover and description.
+- [ ] A portfolio adventure can group one or more completed sessions from the same club.
+- [ ] A public portfolio adventure automatically becomes private if any linked completed session is rescheduled into the future, preserving its first-publication timestamp.
+- [ ] Selected public GM profiles show portfolio cards independently of club-page visibility.
+- [ ] A public club page shows portfolio cards when enabled.
+- [ ] `/portfolio/{slug}` shows cover, description, metadata, selected GMs, and approved player reviews.
+- [ ] A registered participant of a linked completed session can submit one review with explicit publication consent.
+- [ ] Reviews remain non-public until owner/co-GM moderation approves them.
+- [ ] Public DTOs and HTML do not expose private identifiers.
+- [ ] Uploaded covers survive container replacement through a persistent Docker volume.
+- [ ] Storage is isolated behind a replaceable interface for a later S3-compatible implementation.
+- [ ] The existing `/showcase` catalog remains focused on upcoming recruitment games.
