+# Issue #15: Session Audit Log Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** Add transparent audit history for every session change, visible to GM in Web Dashboard.
+
+**Architecture:** PostgreSQL audit table + Dapper queries. Automatic logging inside mutating SessionService methods. New Razor page for GM history view.
+
+**Tech Stack:** C# 12, Blazor SSR, Dapper, PostgreSQL, xUnit.
+
+**Branch:** `issue-15-session-audit-log` (includes mobile UI bugfix cherry-pick)
+
+**Version Bump:** `1.10.1` → `1.10.2`
+
+---
+
+## Task 1: Database Migration (V013)
+
+**Objective:** Create `session_audit_log` table.
+
+**File:** Create `src/GmRelay.Bot/Migrations/V013__add_session_audit_log.sql`
+
+```sql
+CREATE EXTENSION IF NOT EXISTS "pgcrypto";
+
+CREATE TABLE session_audit_log (
+    id                  UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    session_id          UUID NOT NULL REFERENCES sessions(id) ON DELETE CASCADE,
+    actor_telegram_id   BIGINT NOT NULL,
+    actor_name          VARCHAR(255) NOT NULL,
+    change_type          VARCHAR(50) NOT NULL,
+                        CHECK (change_type IN ('Title','Time','Link','MaxPlayers','Status','WaitlistPromote','PlayerRemoved','BatchRescheduled','Cancelled')),
+    old_value           TEXT,
+    new_value           TEXT,
+    changed_at          TIMESTAMPTZ NOT NULL DEFAULT now()
+);
+
+CREATE INDEX ix_session_audit_log_session_id ON session_audit_log(session_id);
+CREATE INDEX ix_session_audit_log_changed_at ON session_audit_log(changed_at);
+```
+
+**Step 2:** Verify migration compiles: `psql $DATABASE_URL -f src/GmRelay.Bot/Migrations/V013__add_session_audit_log.sql` (optional, CI will test)
+
+**Step 3:** Commit: `git add src/GmRelay.Bot/Migrations/V013__add_session_audit_log.sql && git commit -m "chore(#15): add session_audit_log migration"`
+
+---
+
+## Task 2: Domain Model & Interface Methods
+
+**Objective:** Add `SessionAuditLogEntry` record and two new methods to `ISessionStore`.
+
+**Files:**
+- Modify: `src/GmRelay.Web/Services/ISessionStore.cs`
+- Modify: `src/GmRelay.Web/Services/SessionService.cs`
+
+**Step 1: Add record to ISessionStore.cs** (after PlayerAttendanceStats)
+
+```csharp
+public sealed record SessionAuditLogEntry(
+    Guid Id,
+    Guid SessionId,
+    long ActorTelegramId,
+    string ActorName,
+    string ChangeType,
+    string? OldValue,
+    string? NewValue,
+    DateTime ChangedAt
+);
+```
+
+**Step 2: Add methods to ISessionStore interface**
+
+```csharp
+Task LogSessionChangeAsync(Guid sessionId, long actorTelegramId, string actorName, string changeType, string? oldValue, string? newValue);
+Task<List<SessionAuditLogEntry>> GetSessionHistoryAsync(Guid sessionId);
+```
+
+**Step 3: Implement in SessionService.cs**
+
+```csharp
+public async Task LogSessionChangeAsync(Guid sessionId, long actorTelegramId, string actorName, string changeType, string? oldValue, string? newValue)
+{
+    using var connection = new NpgsqlConnection(connectionString);
+    await connection.ExecuteAsync(
+        "INSERT INTO session_audit_log (session_id, actor_telegram_id, actor_name, change_type, old_value, new_value) VALUES (@sessionId, @actorTelegramId, @actorName, @changeType, @oldValue, @newValue)",
+        new { sessionId, actorTelegramId, actorName, changeType, oldValue, newValue });
+}
+
+public async Task<List<SessionAuditLogEntry>> GetSessionHistoryAsync(Guid sessionId)
+{
+    using var connection = new NpgsqlConnection(connectionString);
+    var entries = await connection.QueryAsync<SessionAuditLogEntry>(
+        "SELECT id, session_id as SessionId, actor_telegram_id as ActorTelegramId, actor_name as ActorName, change_type as ChangeType, old_value as OldValue, new_value as NewValue, changed_at as ChangedAt FROM session_audit_log WHERE session_id = @sessionId ORDER BY changed_at DESC",
+        new { sessionId });
+    return entries.ToList();
+}
+```
+
+**Step 4:** Commit: `git add -A && git commit -m "feat(#15): add SessionAuditLogEntry and audit store methods"`
+
+---
+
+## Task 3: Instrument Mutating Methods
+
+**Objective:** Auto-log changes in key methods. Only log when value actually changes.
+
+**File:** Modify `src/GmRelay.Web/Services/SessionService.cs`
+
+**Step 1: Instrument UpdateSessionAsync**
+
+Before executing UPDATE, read current session. After UPDATE, compare and log each changed field:
+
+```csharp
+// After var currentSession = await GetSessionAsync(sessionId);
+// Before the UPDATE SQL:
+
+if (currentSession is not null)
+{
+    if (currentSession.Title != title)
+        await LogSessionChangeAsync(sessionId, /* actor will be passed from caller */ ...);
+}
+```
+
+**Problem:** SessionService doesn't know the actor (GM) telegram ID. Solution: add `long actorTelegramId` parameter to mutating methods, or use a decorator pattern.
+
+**Better approach:** Instrument in `AuthorizedSessionService` which already has `gmId`. That is the authorized wrapper.
+
+**Revised approach:** Add `IAuditLogger` interface and inject it. Or simpler: change `ISessionStore` mutating methods to accept `long actorTelegramId` and `string actorName` as last parameters.
+
+**Simpler approach for this plan:** Since all mutating methods in `ISessionStore` are called through `AuthorizedSessionService`, instrument in `AuthorizedSessionService` methods AFTER the underlying `SessionService` call. BUT we need old values. 
+
+**Final approach:** Change `ISessionStore` methods to include `actorTelegramId` parameter, and inside `SessionService` fetch old values and log.
+
+Let's add `long actorTelegramId` parameter to:
+- `UpdateSessionAsync`
+- `PromoteWaitlistedPlayerAsync`
+- `RemovePlayerFromSessionAsync`
+- `RescheduleBatchAsync`
+
+Wait, this is a bigger change. Let's be more pragmatic: add a new `IAuditService` that can be called from `AuthorizedSessionService` after mutations. `IAuditService` just wraps `ISessionStore.LogSessionChangeAsync`.
+
+Actually, simplest: add `actorTelegramId` and `actorName` parameters to `LogSessionChangeAsync` and call it from `AuthorizedSessionService` after each mutation. For old/new values, read the session before mutation in AuthorizedSessionService.
+
+**Plan:**
+- `AuthorizedSessionService.UpdateSessionForGmAsync`: read session before update, call update, then log differences.
+- Same pattern for other mutating methods.
+
+**Step 1: Read current session in AuthorizedSessionService.UpdateSessionForGmAsync**
+
+```csharp
+public async Task UpdateSessionForGmAsync(Guid sessionId, long gmId, string title, DateTime scheduledAt, string joinLink, int? maxPlayers)
+{
+    var groupId = await EnforceSessionOwnershipAsync(sessionId, gmId);
+    var before = await store.GetSessionAsync(sessionId);  // add this
+    await store.UpdateSessionAsync(sessionId, groupId, title, scheduledAt, joinLink, maxPlayers);
+    if (before is not null)
+    {
+        if (before.Title != title)
+            await store.LogSessionChangeAsync(sessionId, gmId, "ГМ", "Title", before.Title, title);
+        if (before.ScheduledAt != scheduledAt)
+            await store.LogSessionChangeAsync(sessionId, gmId, "ГМ", "Time", before.ScheduledAt.ToString("O"), scheduledAt.ToString("O"));
+        if (before.JoinLink != joinLink)
+            await store.LogSessionChangeAsync(sessionId, gmId, "ГМ", "Link", before.JoinLink, joinLink);
+        if (before.MaxPlayers != maxPlayers)
+            await store.LogSessionChangeAsync(sessionId, gmId, "ГМ", "MaxPlayers", before.MaxPlayers?.ToString(), maxPlayers?.ToString());
+    }
+}
+```
+
+Wait, `EnforceSessionOwnershipAsync` returns `groupId` but we need it. Let me check the current AuthorizedSessionService code... We saw earlier it does `await EnforceSessionOwnershipAsync(sessionId, gmId)` then calls `store.UpdateSessionAsync`.
+
+Actually, looking at the compact output from earlier, `AuthorizedSessionService` has `EnforceSessionOwnershipAsync` as a private helper. Let me verify.
+
+From the compact output of AuthorizedSessionService earlier:
+```
+public async Task UpdateSessionForGmAsync(Guid sessionId, long gmId, string title, DateTime scheduledAt, string joinLink, int? maxPlayers)
+{
+    var groupId = await EnforceSessionOwnershipAsync(sessionId, gmId);
+    await store.UpdateSessionAsync(sessionId, groupId, title, scheduledAt, joinLink, maxPlayers);
+}
+```
+
+So it DOES return groupId. Perfect.
+
+But we need actor name. We can use the GM's display name from `GetGroupManagementForGmAsync` or just hardcode "ГМ" for now. Or we can query the player name. For simplicity, use "ГМ" + telegram ID, or query the player display name.
+
+Actually, let's query the GM name from the group or just use telegram ID as identifier. Since this is audit log, having human-readable name is better. We can pass `actorName` to the log method.
+
+Simpler: In `AuthorizedSessionService`, after `EnforceSessionOwnershipAsync`, we already know the group. We can get the GM name from group or just use a generic "ГМ" label. Actually, the telegram ID is sufficient for audit, and the display name can be resolved later in the UI.
+
+Let's just log `actor_telegram_id` and use "ГМ" as actor_name. Or better, query the player display name if needed.
+
+For this plan, let's keep it simple: log with `gmId` as actor_telegram_id and `"ГМ"` as actor_name. The UI can resolve the name.
+
+**Step 2: Instrument all mutating AuthorizedSessionService methods**
+
+Do this for:
+- `UpdateSessionForGmAsync` (Title, Time, Link, MaxPlayers)
+- `RescheduleBatchForGmAsync` (BatchRescheduled)
+- `PromoteWaitlistedPlayerForGmAsync` (WaitlistPromote)
+- `RemovePlayerFromSessionForGmAsync` (PlayerRemoved)
+- `UpdateBatchDetailsForGmAsync` (Title, Link)
+- `UpdateBatchNotificationModeForGmAsync` (maybe skip, internal)
+- `DeleteSessionHandler` in Bot features (Cancelled) — this is in Bot layer, not Web
+
+For Cancelled status, we need to instrument `CancelSessionHandler` in Bot. But the Bot handlers don't use `ISessionStore` directly... they use `SessionService` or direct SQL. Let me check.
+
+Actually, for this plan, focus on Web layer mutations first. Bot layer can be a follow-up.
+
+**Step 3: Commit:** `git add -A && git commit -m "feat(#15): instrument audit logging in AuthorizedSessionService"`
+
+---
+
+## Task 4: Web Page - SessionHistory.razor
+
+**Objective:** GM-visible timeline of session changes.
+
+**Files:**
+- Create: `src/GmRelay.Web/Components/Pages/SessionHistory.razor`
+- Modify: `src/GmRelay.Web/Components/Pages/GroupDetails.razor` (add "История" link)
+- Modify: `src/GmRelay.Web/Components/Pages/EditSession.razor` (add "История" link)
+
+**Step 1: Create SessionHistory.razor**
+
+Route: `@page "/session/{SessionId:guid}/history"`
+
+Layout: table with columns: Время, Актор, Тип изменения, Было, Стало.
+
+Colors: use existing CSS variables.
+
+**Step 2: Add navigation links**
+
+In GroupDetails.razor sessions table: add 📜 История column/link.
+In EditSession.razor: add button "📜 История изменений" linking to `/session/{SessionId}/history`.
+
+**Step 3: Commit:** `git add -A && git commit -m "feat(#15): add SessionHistory.razor page with audit timeline"`
+
+---
+
+## Task 5: FakeSessionStore + TDD Tests
+
+**Objective:** Test audit logging. RED-GREEN-REFACTOR.
+
+**Files:**
+- Modify: `tests/GmRelay.Bot.Tests/Web/AuthorizedSessionServiceTests.cs`
+
+**Step 1: RED — Write failing test**
+
+```csharp
+[Fact]
+public async Task UpdateSessionForGmAsync_LogsAudit_WhenTitleChanges()
+{
+    var gmId = 1001L;
+    var groupId = Guid.NewGuid();
+    var sessionId = Guid.NewGuid();
+    var store = new FakeSessionStore(
+        groups: [new(groupId, 42, "Alpha", gmId)],
+        sessions: [new(sessionId, groupId, "Session A", DateTime.UtcNow, "Planned", "https://example.test/a", Guid.NewGuid(), 10, 42, 4, 1, 0)]);
+    var service = new AuthorizedSessionService(store);
+
+    await service.UpdateSessionForGmAsync(sessionId, gmId, "Updated Title", DateTime.UtcNow.AddDays(1), "https://example.test/b", 5);
+
+    Assert.Single(store.LogEntries);
+    Assert.Equal("Title", store.LogEntries[0].ChangeType);
+    Assert.Equal("Session A", store.LogEntries[0].OldValue);
+    Assert.Equal("Updated Title", store.LogEntries[0].NewValue);
+}
+```
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/Web/AuthorizedSessionServiceTests.cs --filter "FullyQualifiedName~LogsAudit" -v n`
+Expected: FAIL (FakeSessionStore doesn't have LogSessionChangeAsync / LogEntries)
+
+**Step 2: GREEN — Add to FakeSessionStore**
+
+Add `List<SessionAuditLogEntry> LogEntries` and implement `LogSessionChangeAsync` / `GetSessionHistoryAsync`.
+
+**Step 3: Refactor — Add more tests**
+
+- No audit when values unchanged
+- Audit for time change
+- Audit for link change
+- Audit for max players change
+- GetSessionHistoryAsync returns entries ordered by time desc
+
+**Step 4: Full suite**
+Run: `dotnet test tests/GmRelay.Bot.Tests/GmRelay.Bot.Tests.csproj`
+Expected: all pass
+
+**Step 5: Commit:** `git add -A && git commit -m "test(#15): add audit logging TDD tests"`
+
+---
+
+## Task 6: Bump Version & Docs
+
+**Objective:** Update version and documentation.
+
+**Files:**
+- Modify: `Directory.Build.props`
+- Modify: `compose.yaml`
+- Modify: `README.md`
+- Modify: Wiki «Руководство ГМа»
+
+**Step 1: Bump version to 1.10.2**
+
+**Step 2: Update README** — add "📜 История изменений сессии" bullet in Web Dashboard section.
+
+**Step 3: Update wiki** — add subsection «Журнал действий» with description of how to access `/session/{id}/history`, what change types are tracked, and how to read the timeline.
+
+**Step 4: Commit:** `git add -A && git commit -m "docs(#15): bump version to 1.10.2 and add audit log docs"`
+
+---
+
+## Task 7: Push & PR
+
+**Step 1:** `git push origin issue-15-session-audit-log`

+# Issue #19: выровнять /newsession с batch-сценарием лендинга — Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** Убедиться, что Telegram UX `/newsession` полностью соответствует batch-сценарию лендинга: мастер одной командой создаёт несколько дат, указывает лимит мест и ссылку, получает единую карточку с действиями. Обеспечить покрытие acceptance criteria регрессионными тестами и устранить найденные расхождения.
+
+**Architecture:** Сценарий уже реализован в `CreateSessionHandler` + `NewSessionCommandParser` + `SessionBatchRenderer`. Основная задача — добавить недостающие тесты на «точный» landing-сценарий (несколько явных дат, не recurring), проверить отсутствие частичных сессий при любых ошибках, и убедиться, что карточка содержит все обещанные элементы.
+
+**Tech Stack:** .NET 10, xUnit, Dapper, Npgsql, Telegram.Bot, Native AOT.
+
+---
+
+## Контекст кодовой базы
+
+- `src/GmRelay.Bot/Features/Sessions/CreateSession/CreateSessionHandler.cs` — создание batch, транзакция БД, отправка карточки.
+- `src/GmRelay.Bot/Features/Sessions/CreateSession/NewSessionCommandParser.cs` — парсинг команды: несколько `Время:`, `Мест:`, `Ссылка:`, `Картинка:`, recurring (`Игр:` + `Интервал:`).
+- `src/GmRelay.Shared/Rendering/SessionBatchRenderer.cs` — рендеринг HTML-карточки с кнопками.
+- `src/GmRelay.Shared/Rendering/BatchMessageEditor.cs` — редактирование batch-сообщения (text/photo).
+- `src/GmRelay.Bot/Infrastructure/Telegram/UpdateRouter.cs` — роутинг команд, текст `/help`.
+- `tests/GmRelay.Bot.Tests/Features/Sessions/CreateSession/NewSessionCommandParserTests.cs` — тесты парсера.
+- `tests/GmRelay.Bot.Tests/Features/Landing/TelegramLandingPromisesSmokeTests.cs` — smoke-тест всего landing-флоу через `FakeTelegramMessenger`.
+- `tests/GmRelay.Bot.Tests/Rendering/SessionBatchRendererTests.cs` — тесты рендерера.
+
+---
+
+### Task 1: RED — тест landing-парсинга с несколькими явными датами
+
+**Objective:** Проверить, что парсер корректно обрабатывает точный формат из лендинга: 2+ явных даты, лимит мест, ссылка, без recurring.
+

+
+**Step 2: Run test to verify failure**
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/ --filter "FullyQualifiedName~Render_ShouldProduceLandingBatchCardWithAllRequiredElements" -v n`
+
+Expected: PASS (рендерер уже реализован, тест отсутствовал).
+
+**Step 3: Commit**
+
+```bash
+git add tests/GmRelay.Bot.Tests/Rendering/SessionBatchRendererTests.cs
+git commit -m "test(#19): landing batch renderer card elements test"
+```
+
+---
+
+### Task 3: RED — тест «ошибки ввода не создают частичных сессий»
+
+**Objective:** Убедиться, что при невалидном вводе `CreateSessionHandler` не создаёт ни одной записи в БД и не публикует карточку.
+
+**Files:**
+- Create: `tests/GmRelay.Bot.Tests/Features/Sessions/CreateSession/CreateSessionHandlerTests.cs`
+- Modify: `src/GmRelay.Bot/Features/Sessions/CreateSession/CreateSessionHandler.cs` (если найдена уязвимость)
+
+**Step 1: Write failing test**
+
+```csharp
+using GmRelay.Bot.Features.Sessions.CreateSession;
+using Npgsql;
+using Telegram.Bot;
+using Microsoft.Extensions.Logging.Abstractions;
+
+namespace GmRelay.Bot.Tests.Features.Sessions.CreateSession;
+
+public sealed class CreateSessionHandlerTests
+{
+    // Примечание: полноценный интеграционный тест с реальной БД требует TestContainer.
+    // Для Native AOT проекта используем подход с in-memory фейком через рефакторинг хендлера.
+    // Ниже — тест-спецификация, которую реализуем через FakeDataSource или рефакторинг.
+}
+```
+
+Поскольку `CreateSessionHandler` напрямую зависит от `NpgsqlDataSource` и `ITelegramBotClient`, для unit-тестирования нужно либо:
+а) использовать интеграционный тест с PostgreSQL (TestContainers), либо
+б) рефакторить хендлер, выделив `ISessionRepository`.
+
+**Рекомендуемый подход (YAGNI):** добавить интеграционный тест в smoke-стиле через `FakeTelegramMessenger`, дополнив `TelegramLandingSmokeScenario` сценарием «invalid command does not publish anything».
+
+**Step 1 (реализация):** Дописать тест в `TelegramLandingPromisesSmokeTests.cs`:
+
+```csharp
+[Fact]
+public void Smoke_InvalidNewSession_ShouldNotPublishAnySessions()
+{
+    var nowUtc = new DateTimeOffset(2026, 5, 1, 12, 0, 0, TimeSpan.Zero);
+    var invalidText = """
+        /newsession
+        Название: Bad Game
+        Время: 01.01.2020 19:30
+        """; // нет ссылки
+
+    var parseResult = NewSessionCommandParser.Parse(invalidText, nowUtc);
+
+    Assert.False(parseResult.IsValid);
+    Assert.Empty(parseResult.ScheduledTimes);
+    // Убеждаемся, что smoke-сценарий не может быть опубликован
+    Assert.Throws<InvalidOperationException>(() =>
+        TelegramLandingSmokeScenario.Publish(parseResult, SessionNotificationMode.GroupAndDirect));
+}
+```
+
+В `TelegramLandingSmokeScenario.Publish` добавить guard:
+```csharp
+if (!parseResult.IsValid)
+    throw new InvalidOperationException("Cannot publish invalid parse result");
+```
+
+**Step 2: Run test to verify failure**
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/ --filter "FullyQualifiedName~Smoke_InvalidNewSession_ShouldNotPublishAnySessions" -v n`
+
+Expected: FAIL — guard ещё не добавлен.
+
+**Step 3: Write minimal implementation**
+
+Добавить guard в `TelegramLandingSmokeScenario.Publish`:
+```csharp
+if (!parseResult.IsValid)
+    throw new InvalidOperationException("Cannot publish invalid parse result");
+```
+
+**Step 4: Run test to verify pass**
+
+Expected: PASS.
+
+**Step 5: Commit**
+
+```bash
+git add tests/GmRelay.Bot.Tests/Features/Landing/TelegramLandingPromisesSmokeTests.cs
+git add src/GmRelay.Bot/... # если были изменения
+# (файл CreateSessionHandler.cs не трогаем — валидация происходит ДО транзакции)
+git commit -m "test(#19): ensure invalid parse does not publish partial sessions"
+```
+
+---
+
+### Task 4: RED — тест atomicity при сбое отправки batch-сообщения
+
+**Objective:** В `CreateSessionHandler` `batch_message_id` обновляется ПОСЛЕ `transaction.Commit()`. Если отправка сообщения в Telegram падает, сессии созданы, но `batch_message_id` не записан — игроки не увидят карточку. Нужно либо доказать, что это обработано, либо исправить.
+
+**Files:**
+- Modify: `src/GmRelay.Bot/Features/Sessions/CreateSession/CreateSessionHandler.cs`
+
+**Step 1: Анализ кода**
+
+Текущий порядок в `CreateSessionHandler`:
+1. Валидация (до транзакции) ✓
+2. `BEGIN TRANSACTION`
+3. INSERT players, groups, sessions
+4. `COMMIT`
+5. `SessionBatchRenderer.Render`
+6. `botClient.SendMessage/SendPhoto`
+7. `UPDATE sessions SET batch_message_id = ...` (вне транзакции!)
+
+Если шаг 6 падает — сессии «висят» без published message. Это частичное создание.
+
+**Step 2: Write minimal fix**
+
+Обернуть отправку сообщения и обновление `batch_message_id` в retry-loop с fallback. Если после N попыток не удалось — отправить GM уведомление об ошибке и оставить сессии (не удалять, чтобы не терять данные), но сделать так, чтобы `batch_message_id` обновлялся только при успешной отправке.
+
+```csharp
+// Внутри CreateSessionHandler, после Commit:
+Message? batchMessage = null;
+var sendAttempts = 0;
+const int maxAttempts = 3;
+Exception? lastSendException = null;
+
+while (batchMessage is null && sendAttempts < maxAttempts)
+{
+    sendAttempts++;
+    try
+    {
+        batchMessage = await SendBatchMessageAsync(...); // extracted method
+    }
+    catch (Exception ex)
+    {
+        lastSendException = ex;
+        logger.LogWarning(ex, "Attempt {Attempt} failed to send batch message for {BatchId}", sendAttempts, batchId);
+        if (sendAttempts < maxAttempts)
+            await Task.Delay(TimeSpan.FromSeconds(1), cancellationToken);
+    }
+}
+
+if (batchMessage is not null)
+{
+    await connection.ExecuteAsync(
+        "UPDATE sessions SET batch_message_id = @MsgId WHERE batch_id = @BatchId",
+        new { MsgId = batchMessage.MessageId, BatchId = batchId });
+}
+else
+{
+    logger.LogError(lastSendException, "Failed to send batch message for {BatchId} after {MaxAttempts} attempts", batchId, maxAttempts);
+    await botClient.SendMessage(
+        chatId,
+        $"⚠️ Сессии созданы, но не удалось опубликовать карточку. Пожалуйста, используйте /listsessions.\n\nОшибка: {lastSendException?.Message}",
+        cancellationToken: cancellationToken);
+}
+```
+
+**Step 3: Extract helper**
+
+Выделить метод `SendBatchMessageAsync` из текущего inline-кода отправки (строки 117–176 в текущем файле), чтобы логика была читаемой и тестируемой.
+
+**Step 4: Run tests**
+
+Run: `dotnet test tests/GmRelay.Bot.Tests/ -v n`
+
+Expected: все существующие тесты PASS, новая логика не ломает smoke-тест (т.к. smoke-тест не использует реальный `CreateSessionHandler`).
+
+**Step 5: Commit**
+
+```bash
+git add src/GmRelay.Bot/Features/Sessions/CreateSession/CreateSessionHandler.cs
+git commit -m "fix(#19): retry batch message send and prevent orphaned sessions without batch_message_id"
+```
+
+---
+
+### Task 5: RED — smoke-тест полного landing-сценария с явными датами
+
+**Objective:** Дополнить `TelegramLandingPromisesSmokeTests` полным сквозным сценарием: парсинг → публикация → запись → выход → проверка карточки.
+
+**Files:**
+- Modify: `tests/GmRelay.Bot.Tests/Features/Landing/TelegramLandingPromisesSmokeTests.cs`
+
+**Step 1: Write failing test**
+
+```csharp

+### Task 6: Проверка и обновление `/help` текста
+
+**Objective:** Убедиться, что текст `/help` точно отражает landing-формат и упоминает batch-сценарий.
+
+**Files:**
+- Modify: `src/GmRelay.Bot/Infrastructure/Telegram/UpdateRouter.cs`

+- **🖼 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.
+- **❌ 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**: При переносе сессии GM предлагает 2-3 новых времени и дедлайн, игроки голосуют кнопками, а бот показывает текущие результаты и применяет победивший вариант.
+- **🔄 Голосование за перенос**: Быстрый поиск свободного места с через свободное недель и кнопками новых времени и дедлайном.
-- **🔔 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.
+- **🔔 Уведомления**: Игрок получают 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.
+- **🕐 Режим уведомлений batch**: Для каждой пачки можно выбрать `В группе и в личку` или `Только в группе`.

 ## 🚀 Быстрый старт (Docker Compose)
 
-Проект использует Docker Compose для одновременного запуска базы данных, бота и веб-интерфейса.
+**Требования:** Docker и Docker Compose.
-
-### 1. Подготовка
-Убедитесь, что у вас установлены **Docker** и **Docker Compose**.
-
-### 2. Настройка окружения
-Скопируйте файл-шаблон и заполните его значениями:
 
+### 1. Настройка окружения
 ```bash
 cp .env.example .env
 ```
 
-Отредактируйте `.env`:
+**Ключевые переменные `.env`:**
-
 ```env
-# Токен вашего бота от @BotFather (используется и для бота, и как секретный ключ для веб-авторизации)
+# Токен от @BotFather (используется ботом и как секретный ключ веб-авторизации)
 TELEGRAM_BOT_TOKEN=ваш_токен_здесь
 
-# Имя вашего бота в Telegram (без @), например: GmRelayBot.
+# Имя бота без @ (для Telegram Login Widget)
-# Найти его можно в информации о боте у @BotFather. 
-# Используется для работы виджета авторизации (Telegram Login Widget).
 TELEGRAM_BOT_USERNAME=ваше_имя_бота_здесь
 
-# Пароль для базы данных PostgreSQL
+# HTTPS URL Mini App, например https://your-domain.example/miniapp
-POSTGRES_PASSWORD=ваш_надежный_пароль
+TELEGRAM_MINI_APP_URL=https://your-domain.example/miniapp
 
-# Локальный порт веб-интерфейса GM-Relay
+POSTGRES_PASSWORD=ваш_надежный_пароль
 GMRELAY_WEB_PORT=8080
 ```
 
-*(Опционально)* Настройте домен Telegram бота в @BotFather командой `/setdomain` для работы виджета авторизации на вашем сайте.
+**Настройка в @BotFather:**
+- Команда `/setdomain` для работы виджета авторизации на вашем домене.
+- Для Mini App настройте домен Web Dashboard и menu button на URL из `TELEGRAM_MINI_APP_URL`.
+- Начиная с **v1.9.3** дополнительных действий для фикса входа не требуется: fallback выполняется внутри активного Telegram WebView по тому же HTTPS-адресу `/miniapp`.
 
-### 3. Запуск
+### 2. Запуск
-Выполните команду:
 ```bash
 docker compose up -d
 ```
-Инфраструктура автоматически:
+
-- Создаст локальную Docker-сеть и volume PostgreSQL, если их ещё нет.
+**Автоматически выполняется:**
-- Поднимет PostgreSQL, доступный для контейнеров как `db:5432`.
+- создание Docker-сети и volume PostgreSQL;
-- Запустит бота (применив миграции БД).
+- подъём PostgreSQL (`db:5432`);
-- Запустит веб-интерфейс на `http://localhost:8080` или другом порту из `GMRELAY_WEB_PORT`.
+- запуск бота с плавной миграцией (DbUp);
+- 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.
 
 ---
 
-## ⚙️ 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.

-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.
-
-### 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.

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

+# Player List + Kick + Waitlist Promotion Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** Add a player list (with names) to the Web UI session views, allow GM to kick a specific player, and auto-promote the next waitlisted player.
+
+**Architecture:** Extend `ISessionStore` with participant queries and a remove method. Update `GroupDetails.razor` to show expandable participant lists. Reuse existing `PromoteWaitlistedPlayerAsync` logic after removal.
+
+**Tech Stack:** C# 14, Blazor SSR, Dapper, PostgreSQL
+

+# 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`
+- Modify: `src/GmRelay.Web/Components/App.razor`
+- Modify: `src/GmRelay.Web/wwwroot/app.css`
+- Test: `tests/GmRelay.Bot.Tests/Web/MiniAppDashboardTests.cs`
+
+- [ ] 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/Infrastructure/Telegram/UpdateRouter.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`
+- Modify: `compose.yaml`
+- Modify: `.gitea/workflows/deploy.yml`
+- Modify: `src/GmRelay.Web/wwwroot/app.css`
+- Modify: `src/GmRelay.Web/Components/Layout/NavMenu.razor`
+- Modify: `README.md`
+- Wiki: `Home`, `Быстрый старт`, `Руководство ГМа`, `Развёртывание`, `Архитектура`, `Разработка`
+
+- [ ] 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.
