Merge pull request #85: feat(discord): implement /newsession and /listsessions (issue #28)

- DiscordNewSessionCommand: on success, renders session details via
  DiscordSessionBatchRenderer.Render() with embeds and action rows.
- DiscordNewSessionCommand: uses Discord emoji shortcodes for error
  and success messages (✅, ⛔, 💥).
- DiscordNewSessionHandlerTests: added 7 source-level structural tests
  verifying Dapper usage, NpgsqlDataSource, permission checks,
  platform neutrality, transaction safety, CancellationToken usage,
  and embed rendering in the command.

+
+## 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.

+# Discord NetCord Gateway 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 separate `src/GmRelay.DiscordBot` worker that uses NetCord Gateway for Discord slash commands and component interactions while keeping Telegram dependencies isolated in `src/GmRelay.Bot`.
+
+**Architecture:** Create a new .NET worker project that references `GmRelay.ServiceDefaults` and `GmRelay.Shared`, validates `Discord:Token` during startup, registers NetCord gateway/application command/component services, and logs gateway lifecycle events through NetCord gateway handlers. Keep database connectivity aligned with the existing worker by registering the same `ConnectionStrings:gmrelaydb` `NpgsqlDataSource` pattern, but do not move Telegram code or dependencies.
+
+**Tech Stack:** .NET 10 worker, Aspire service defaults, NetCord.Hosting `1.0.0-alpha.489`, Npgsql `10.0.2`, xUnit, Docker Compose, Gitea Actions.

+
+Use the Discord-local `SecretRedactor` namespace instead of `GmRelay.Bot.Infrastructure.Logging` so the new project does not reference the Telegram worker.
+
+Create `src/GmRelay.DiscordBot/Infrastructure/Logging/SecretRedactor.cs`:

+
+If interface signatures differ in `1.0.0-alpha.489`, inspect the package XML/docs and adjust the handlers to compile while keeping ready/disconnect/resume logging and never logging token values.

+- [ ] **Step 2: Run targeted tests**
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter FullyQualifiedName~Discord`
+
+Expected: all Discord tests pass.
+
+- [ ] **Step 3: Run full tests**
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --verbosity normal`
+
+Expected: all tests pass.
+
+- [ ] **Step 4: Run release build**
+
+Run: `dotnet build GM-Relay.slnx -c Release`

+Run: `git diff -- . ':!*.lock.json'`
+
+Expected: diff contains configuration variable names such as `Discord__Token` and `DISCORD_BOT_TOKEN`, but not a real token value.
+
+### Task 8: Commit, PR, CI, Deploy, Release, Issue Closure
+
+**Files:**
+- All intended implementation, test, lock, workflow, compose, and version files.
+
+- [ ] **Step 1: Create commit**
+
+Run:
+
+```powershell
+git status --short
+git add GM-Relay.slnx Directory.Build.props compose.yaml .gitea/workflows/deploy.yml .gitea/workflows/pr-checks.yml src/GmRelay.AppHost src/GmRelay.DiscordBot src/GmRelay.Web/Components/Layout/NavMenu.razor tests/GmRelay.Bot.Tests
+git commit -m "feat: add Discord NetCord gateway worker"
+```
+
+Expected: only intended files are staged and committed. Do not stage untracked `CLAUDE.md`.
+
+- [ ] **Step 2: Push branch and open PR**
+
+Run: `git push -u origin feature/issue-26-discord-netcord-gateway`
+
+Create Gitea PR to `main` with:
+- Summary of Discord worker, token validation, runtime wiring, and version bump.
+- Test plan showing targeted Discord tests, full tests, release build, format, and secret diff inspection.
+- Link to issue `#26`.
+
+- [ ] **Step 3: Store Discord token as a Gitea Actions secret**
+
+Use Gitea Actions configuration to create or update repository secret `DISCORD_BOT_TOKEN` with the user-provided Discord bot token.
+
+Expected: token is stored only as an Actions secret. The token value is not written to source files, plan files, logs, PR text, release notes, or commits.
+
+- [ ] **Step 4: Monitor CI**
+
+Use Gitea Actions run reads until PR checks finish. If CI fails, inspect logs, fix with TDD where the failure is code behavior, push again, and re-check.
+
+- [ ] **Step 5: Review, merge, deploy, release**
+
+After CI passes and review is approved:
+- Merge PR.
+- Monitor deploy workflow on `main`.
+- Create release `v2.2.0` with Russian release notes.
+- Close issue `#26` with a comment linking PR and release.
+
+## Self-Review
+
+- Spec coverage: Project creation, NetCord Gateway, slash/component service registration, `Discord__Token`, PostgreSQL service defaults, lifecycle logging, Telegram isolation, solution build, compose/deploy integration, and version sync are covered.
+- Placeholder scan: No task uses `TBD`, `TODO`, or an unspecified "add tests" instruction.
+- Type consistency: Test class names and file paths are consistent across tasks; NetCord lifecycle handler signatures are explicitly marked for compile-driven adjustment because the package is prerelease and must be verified against installed `1.0.0-alpha.489`.

+# Discord /newsession и /listsessions — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:test-driven-development (TDD) for every task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Реализовать slash-команды `/newsession` и `/listsessions` в Discord-боте, позволяющие создавать батчи сессий и просматривать расписание без Web Dashboard.
+
+**Architecture:** Каждая команда — отдельный vertical slice в `GmRelay.DiscordBot`: парсер входных данных → handler с SQL (через Dapper) → отправка через NetCord REST API. Рендеринг переиспользует существующий `DiscordSessionBatchRenderer`. Данные пишутся в общую PostgreSQL модель через platform-agnostic колонки (`platform`, `external_group_id`, `external_user_id`).
+
+**Tech Stack:** .NET 10, NetCord 1.0.0-alpha.489, NetCord.Hosting.Services, Dapper, Npgsql, xUnit.
+
+**Version Bump:** minor (2.3.0 → 2.4.0) — новый функционал.

+## Task 1: DiscordPermissionChecker
+
+**Files:**
+- Create: `src/GmRelay.DiscordBot/Infrastructure/Discord/DiscordPermissionChecker.cs`
+- Test: `tests/GmRelay.Bot.Tests/Discord/DiscordPermissionCheckerTests.cs`
+
+**Context:** Discord использует guild-роли. Для MVP достаточно проверки: пользователь — owner guild, имеет роль `Administrator`, или записан как `group_managers` в БД для данной `game_groups`.
+
+### Step 1.1: Write the failing test

+## Task 4: DiscordPlatformMessenger
+
+**Files:**
+- Create: `src/GmRelay.DiscordBot/Infrastructure/Discord/DiscordPlatformMessenger.cs`
+- Test: `tests/GmRelay.Bot.Tests/Discord/DiscordPlatformMessengerTests.cs`
+
+**Context:** Необходима реализация `IPlatformMessenger` для отправки schedule embeds и обновления существующих сообщений в Discord. Для MVP достаточно `SendScheduleAsync` и `UpdateScheduleAsync` (stub для остальных).
+
+### Step 4.1: Write the failing test
+
+Create `tests/GmRelay.Bot.Tests/Discord/DiscordPlatformMessengerTests.cs`:
+
+```csharp
+using GmRelay.DiscordBot.Infrastructure.Discord;
+using GmRelay.Shared.Platform;
+using GmRelay.Shared.Rendering;

+        var constructor = typeof(DiscordPlatformMessenger).GetConstructor(new[] { typeof(NetCord.Rest.RestClient) });

+
+### Step 4.2: Run test — verify RED
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter "FullyQualifiedName~DiscordPlatformMessengerTests" --verbosity normal`
+Expected: FAIL — `DiscordPlatformMessenger` not found.
+
+### Step 4.3: Write minimal implementation
+

+
+```csharp

+
+## Task 5: Wire up DI and Register Commands
+
+**Files:**
+- Modify: `src/GmRelay.DiscordBot/Program.cs`
+
+### Step 5.1: Write the failing test (structure test)
+
+Modify `tests/GmRelay.Bot.Tests/Discord/DiscordStartupTests.cs` — add test that asserts new handlers are registered:
+
+```csharp
+[Fact]
+public void Program_ShouldRegisterDiscordSessionHandlers()
+{
+    var program = ReadProgram();
+    Assert.Contains("DiscordListSessionsHandler", program);
+    Assert.Contains("DiscordNewSessionHandler", program);
+    Assert.Contains("DiscordPermissionChecker", program);
+    Assert.Contains("DiscordPlatformMessenger", program);
+    Assert.Contains("IPlatformMessenger", program);
+}
+```
+
+### Step 5.2: Run test — verify RED
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter "FullyQualifiedName~DiscordStartupTests" --verbosity normal`
+Expected: FAIL — asserts not found in Program.cs.
+
+### Step 5.3: Write minimal implementation
+
+Modify `src/GmRelay.DiscordBot/Program.cs`:
+
+```csharp
+using GmRelay.DiscordBot.Features.Sessions;
+using GmRelay.DiscordBot.Infrastructure.Discord;
+using GmRelay.Shared.Platform;
+
+// ... existing usings ...
+
+builder.Services.AddSingleton<DiscordPermissionChecker>();
+builder.Services.AddSingleton<DiscordListSessionsHandler>();
+builder.Services.AddSingleton<DiscordNewSessionHandler>();
+builder.Services.AddSingleton<IPlatformMessenger, DiscordPlatformMessenger>();
+
+// After host.Build():
+host.AddSlashCommand("listsessions", "Show upcoming game sessions", async (DiscordListSessionsHandler handler, SlashCommandContext context) =>
+{
+    // NetCord module-based approach preferred; if AddSlashCommand lambda doesn't support DI injection of custom services,
+    // rely on module classes registered via AddApplicationCommands
+});
+```
+
+**Important:** NetCord module classes (`DiscordListSessionsCommand`, `DiscordNewSessionCommand`) автоматически регистрируются через `AddApplicationCommands()` + `AddGatewayHandlers(typeof(Program).Assembly)`. Constructor injection в модулях работает через DI контейнер. Никаких дополнительных `AddSlashCommand` для модулей не требуется.
+
+Убедиться, что в Program.cs есть:
+```csharp
+builder.Services.AddSingleton<DiscordPermissionChecker>();
+builder.Services.AddSingleton<DiscordListSessionsHandler>();
+builder.Services.AddSingleton<DiscordNewSessionHandler>();
+builder.Services.AddSingleton<IPlatformMessenger, DiscordPlatformMessenger>();
+```
+
+### Step 5.4: Run test — verify GREEN
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter "FullyQualifiedName~DiscordStartupTests" --verbosity normal`
+Expected: PASS.
+
+### Step 5.5: Commit
+
+```bash
+git add src/GmRelay.DiscordBot/Program.cs tests/GmRelay.Bot.Tests/Discord/DiscordStartupTests.cs
+git commit -m "feat(discord): wire up DI registrations for session handlers and messenger
+
+Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>"
+```
+
+---
+
+## Task 6: Build Verification
+
+### Step 6.1: Build DiscordBot project
+
+Run: `dotnet build src/GmRelay.DiscordBot/GmRelay.DiscordBot.csproj --no-restore`
+Expected: Build succeeds (0 errors, 0 warnings).
+
+### Step 6.2: Run all tests
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --verbosity normal`
+Expected: All tests pass.
+
+### Step 6.3: Commit if any fixes needed
+
+If build or tests required fixes, commit them.
+
+---
+
+## Task 7: Version Bump
+
+**Files to modify:**
+- `Directory.Build.props`: `<Version>2.4.0</Version>`
+- `compose.yaml`: обновить теги `gmrelay-bot`, `gmrelay-web`, `gmrelay-discord-bot` → `2.4.0`
+- `.gitea/workflows/deploy.yml`: `VERSION: 2.4.0`
+- `src/GmRelay.Web/Components/Layout/NavMenu.razor`: `<div class="nav-version">v2.4.0</div>`
+
+### Step 7.1: Bump version
+
+Apply изменения ко всем 4 файлам.
+
+### Step 7.2: Update version test
+
+Modify `tests/GmRelay.Bot.Tests/Discord/DiscordProjectStructureTests.cs` — обновить `Version_ShouldBeSynchronizedForDiscordFeatureRelease` ожидаемое значение на `2.4.0`.
+
+### Step 7.3: Run version test
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj --filter "FullyQualifiedName~Version_ShouldBeSynchronizedForDiscordFeatureRelease" --verbosity normal`
+Expected: PASS.
+
+### Step 7.4: Commit
+
+```bash
+git add Directory.Build.props compose.yaml .gitea/workflows/deploy.yml src/GmRelay.Web/Components/Layout/NavMenu.razor tests/GmRelay.Bot.Tests/Discord/DiscordProjectStructureTests.cs
+git commit -m "chore: bump version to 2.4.0

+
+## Spec Coverage Self-Review
+
+| Issue Requirement | Task |
+|---|---|
+| Slash command `/newsession` | Task 3 |
+| Slash command `/listsessions` | Task 2 |
+| Сохранение platform group identity (guild/channel) | Task 3 (game_groups.platform, external_group_id, external_channel_id) |
+| Минимальная проверка прав | Task 1 + Task 3 |
+| Данные пишутся в общую PostgreSQL без Telegram-only assumptions | Task 2, 3 SQL используют platform-agnostic колонки |
+| `/listsessions` публикует/обновляет расписание | Task 2 + Task 4 |
+
+**Placeholder scan:** Нет TBD, TODO, "implement later". Каждый шаг содержит конкретный код.
+
+**Type consistency:** `DiscordPermissionChecker.CanManageSchedule` перегружен для resolved permissions (ulong bitflag). Handler передает `Context.GuildUser.RoleIds` и `guild.OwnerId`.
+
+---
+
+## Execution Handoff
+
+**Plan complete and saved to `docs/superpowers/plans/2026-05-19-discord-newsession-listsessions.md`.**
+
+**Two execution options:**
+
+1. **Subagent-Driven (recommended)** — I dispatch a fresh subagent per task, review between tasks, fast iteration
+2. **Inline Execution** — Execute tasks in this session using executing-plans, batch execution with checkpoints for review
+
+**Which approach?**
