fix(bot): trim misleading comment in IsComplete

The previous comment claimed a 0 MaxPlayers would also be blocked, but
the code never actually enforced that. The wizard's text-input path
already guarantees cap >= MinCapacity, so 0 is unreachable. Drop the
inaccurate half-sentence to keep the comment faithful to the code.

+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.

-## 🛠 Patch 2.4.0 — Discord /newsession и /listsessions
+## 🐞 Patch 3.9.2 — Hotfix: club-picker молча падал на шаге «Видимость» (3.9.1 неполный)
+
+В 3.9.1 был починен только `WizardDraftRepository` (самый частый путь). Тот же баг с `(CommandDefinition)`-оверлоадом Dapper остался в 4 клуб-пикерах / permission-локапах — Wizard доходил до шага «Видимость», и при выборе «Публичная в витрине клуба» / «Только для членов клуба» `PersistAndRenderAsync` дёргал `_messenger.GetOwnerClubsAsync` → `PlatformNotSupportedException` → `GameCreationWizard` глотал исключение → кнопка `ack` отправлялась с тостом «⚠️ Ошибка», но нового шага пользователь не видел. Privacy «не цеплялась».
+
+### 🩹 Что починено
+- `src/GmRelay.Bot/Features/Sessions/CreateSession/Wizard/TelegramWizardMessenger.cs::GetOwnerClubsAsync` — `new CommandDefinition(...)` → прямой `QueryAsync<WizardClubOption>(sql, params)`.
+- `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardMessenger.cs::GetOwnerClubsAsync` — то же.
+- `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardInteractionModule.cs::WizardClubLookup.LoadClubsAsync` — то же.
+- `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordPermissionLookup.cs::LoadManagerUserIdsAsync` — то же.
+- `src/GmRelay.DiscordBot/GmRelay.DiscordBot.csproj` — добавлен `<InterceptorsPreviewNamespaces>$(InterceptorsPreviewNamespaces);Dapper.AOT</InterceptorsPreviewNamespaces>` (раньше был только в Shared и Bot). Без этого `Dapper.AOT`-генератор не сканировал DiscordBot, и `new CommandDefinition`-вызовы в DiscordBot падали бы в рантайме даже после фикса сигнатур.
+- `src/GmRelay.DiscordBot/Program.cs` — добавлен `[module: Dapper.DapperAot]` (раньше только в Bot и Shared).
+- `Directory.Build.props` / `compose.yaml` / `.gitea/workflows/deploy.yml` / `NavMenu.razor` — бамп 3.9.1 → 3.9.2.
+- `tests/.../WizardDraftRepositoryAotShapeTests.cs` — расширены `ClubPickerAndPermissionLookups_ShouldNotUseCommandDefinition` на 4 inline-cases + опциональный `containingClass` для дизамбигуации одинаковых имён методов в DiscordWizardInteractionModule.
+
+### ⚠️ Известные ограничения
+- Web-проект не под NativeAOT (Blazor Server), там `Dapper.AOT` не подключён и используется обычный Dapper; регрессия его не касается.
+
+### 🧪 Тесты
+- 592/594 passed (2 pre-existing skipped), `dotnet format` clean, `dotnet build` 0 warnings/errors, AOT-генератор эмитит интерсепторы для всех 4 клуб-пикеров + `WizardDraftRepository` (всего 5 файлов: 4 в Bot/DiscordBot/DiscordBot + 1 в Shared).
+
+## 🐞 Patch 3.9.1 — Hotfix: Telegram-визард мёртв после 3.9.0
+
+Регрессия в `WizardDraftRepository` (NativeAOT). В Telegram **не реагировали кнопки** и **не создавались игры**, потому что Dapper.AOT 1.0.48 не генерирует интерсепторы для оверлоада `(CommandDefinition)` — рантайм падал в `CreateParamInfoGenerator` → `PlatformNotSupportedException` на каждом апдейте, `TelegramBotService` глотал исключение и апдейт терялся.
+
+### 🩹 Что починено
+- `src/GmRelay.Shared/Features/Sessions/CreateSession/Wizard/WizardDraftRepository.cs` — все 4 метода переписаны с `new CommandDefinition(sql, params, cancellationToken: ct)` на прямой оверлоад `connection.QuerySingleOrDefaultAsync<WizardDraft>(sql, params)` (паттерн `JoinSessionHandler`). Dapper.AOT генерирует интерсепторы только для прямого оверлоада.
+- `src/GmRelay.Shared/Features/Sessions/CreateSession/Wizard/WizardDraft.cs` — `CreatedAt` / `UpdatedAt` / `ExpiresAt` переведены с `DateTimeOffset` на `DateTime` (UTC). AOT RowFactory вызывает `reader.GetDateTime()` напрямую и не делает `DateTime → DateTimeOffset` конверсию.
+- `src/GmRelay.Bot/Features/Sessions/CreateSession/CreateSessionHandler.cs`, `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardCommand.cs` — `DateTimeOffset.UtcNow` → `DateTime.UtcNow` в новых драфтах.
+- `Directory.Build.props` / `compose.yaml` / `.gitea/workflows/deploy.yml` / `NavMenu.razor` — бамп 3.9.0 → 3.9.1.
+- `tests/GmRelay.Bot.Tests/Features/Sessions/CreateSession/Wizard/WizardDraftRepositoryAotShapeTests.cs` — 5 source-grep регрессионных тестов: ни один метод `WizardDraftRepository` не должен использовать `new CommandDefinition`, и три timestamp-свойства `WizardDraft` должны быть `DateTime` (не `DateTimeOffset`).
+
+### ⚠️ Известные ограничения
+- В `TelegramWizardMessenger.GetOwnerClubsAsync`, `DiscordWizardMessenger.GetOwnerClubsAsync`, `DiscordPermissionLookup.LoadManagerUserIdsAsync`, `DiscordWizardInteractionModule.GetOwnerClubsAsync` остаётся `new CommandDefinition`. Эти вызовы **падают на AOT так же**, как падал `WizardDraftRepository` в 3.9.0. Пользователь натыкается на это только когда выбирает «видимость = клуб/мемберы» и доходит до шага выбора клуба. Будет исправлено в 3.9.2 вместе с переводом `DiscordWizardInteractionModule` на прямые Dapper-оверлоады.
+
+### 🧪 Тесты
+- 588/590 passed (2 pre-existing skipped), `dotnet format` clean, `dotnet build` 0 warnings/errors, AOT-генератор эмитит 4 интерсептора + `RowFactory17<WizardDraft>` + `CommandFactory30<WizardDraft>`.
+
+## 🎯 Minor 3.9.0 — Discord-визард создания игры/пула (issue #112)
+
+Пошаговый сценарий создания одиночной игры или пула игр в Discord-чате, по аналогии с Telegram-визардом из 3.8.0. Платформо-нейтральная стейт-машина `GameCreationWizard` и контракт `IWizardMessenger` перенесены в `GmRelay.Shared`, чтобы обе платформы (Telegram/Discord) использовали один и тот же движок визарда.
+
+### 🧩 Что вошло в релиз
+
+**Платформо-нейтральный рефакторинг (GmRelay.Shared)**
+- `Features/Sessions/CreateSession/Wizard/GameCreationWizard.cs` — стейт-машина визарда (один источник правды для обеих платформ)
+- `Features/Sessions/CreateSession/Wizard/IWizardMessenger.cs` — контракт мессенджера (edit/send/answer/getOwnerClubs)
+- `Features/Sessions/CreateSession/Wizard/WizardInteraction.cs` — запись взаимодействия (OwnerId, Text, CallbackPayload, PhotoFileId, PhotoUrl, InteractionId)
+- `Features/Sessions/CreateSession/Wizard/WizardAction.cs`, `WizardKeyboard.cs`, `WizardStepLimits.cs` — модель кнопок и лимитов
+- `Features/Sessions/CreateSession/Wizard/WizardDraft.cs` — добавлено поле `Platform`
+- `Migrations/V032__add_wizard_drafts_platform.sql` — `ALTER TABLE wizard_drafts ADD COLUMN platform TEXT NOT NULL DEFAULT 'Telegram'`
+
+**Discord-адаптер (GmRelay.DiscordBot)**
+- `Features/Sessions/Wizard/DiscordWizardCommand.cs` — slash-команда `/newsession-wizard` с проверкой owner/co-GM через `DiscordPermissionLookup`
+- `Features/Sessions/Wizard/DiscordWizardStep.cs` — рендер 15 шагов в NetCord embed + buttons/StringSelectMenu/modals
+- `Features/Sessions/Wizard/DiscordWizardMessenger.cs` — реализация `IWizardMessenger` через NetCord REST (edit с fallback на re-send при 401/403/404)
+- `Features/Sessions/Wizard/DiscordWizardSubmitter.cs` — финализация с 3-retry циклом
+- `Features/Sessions/Wizard/DiscordWizardContextStore.cs` — in-memory кэш контекста (guild/channel/messageId) для 15-минутного interaction token
+- `Features/Sessions/Wizard/DiscordWizardInteractionModule.cs` — inbound handlers: 3 NetCord `ComponentInteractionModule<TContext>` (button/StringMenu/Modal) + `WizardInteractionDispatcher`
+- `Features/Sessions/Wizard/DiscordPermissionLookup.cs` — DB-хелпер для `group_managers`
+- `Program.cs` — DI-регистрации + 3 `AddComponentInteractions<TInteraction, TContext>`
+
+**Тесты**
+- `tests/GmRelay.Bot.Tests/Features/Sessions/CreateSession/Wizard/*` — обновлены под новый контракт
+- `tests/GmRelay.Bot.Tests/Discord/DiscordWizardInteractionModuleSourceTests.cs` — 12 source-level smoke-тестов на структуру interaction module
+
+### 🗺 Что это даёт
+- Мастера (GM) могут пошагово создавать игры и пулы слотов прямо в Discord через slash-команду, кнопки, выпадающие меню и модальные окна.
+- UX адаптирован под Discord (нативные components), а не скопирован из Telegram.
+- Общая стейт-машина и валидация: Telegram и Discord визарды развиваются синхронно, баги фиксятся в одном месте.
+- PickClub-шаг использует реальный SQL-запрос к `club_memberships` с фильтром по роли Owner/CoGm.
+
+### 📦 Версия и деплой
+- Версия обновлена до 3.9.0 (`NavMenu.razor`, `.gitea/workflows/deploy.yml`)
+- Docker-образы будут тегированы `3.9.0` при пуше в `main`
+- Миграция V032 применяется автоматически на старте Bot

+# Discord wizard adapter — issue #112
+
+## Summary
+
+Implemented the Discord side of the platform-neutral game/pool creation
+wizard (`feat/issue-112-wizard-refactor`). Six adapter files in
+`src/GmRelay.DiscordBot/Features/Sessions/Wizard/` plus one inbound
+handler module turn the `/newsession-wizard` slash command into a
+fully clickable step-by-step wizard with button, StringSelectMenu, and
+modal handlers. The shared `GameCreationWizard` state machine in
+`GmRelay.Shared` is the single source of truth — the Discord adapter
+only translates between NetCord's interaction types and the
+platform-neutral `WizardInteraction` record.
+
+## Files
+
+Adapter (all under `src/GmRelay.DiscordBot/Features/Sessions/Wizard/`):
+
+- `DiscordWizardContextStore.cs` — `IWizardContextStore` interface +
+  thread-safe in-memory store. Keyed by `draft.Id`. Holds the
+  `(GuildId, ChannelId, MessageId, ThreadId?)` snapshot the messenger
+  needs to re-send a draft after a 15-minute interaction token
+  expires.
+- `DiscordWizardStep.cs` — renderer for all 15 wizard steps. Returns
+  an embed + `IReadOnlyList<IMessageComponentProperties>` (mixes
+  `ActionRow` buttons with `StringMenu` select menus) and exposes
+  `BuildModal` for the 8 modal-collecting steps.
+- `DiscordWizardMessenger.cs` — `IWizardMessenger` impl. Uses
+  `RestClient.SendMessageAsync` / `ModifyMessageAsync` (edit falls
+  back to re-send on 401/403/404). Toast replies are stashed in the
+  existing `DiscordInteractionReplyCache`.
+- `DiscordWizardSubmitter.cs` — 3-retry finalize loop. Builds the
+  shared `CreateSessionCommand` and calls `CreateSessionHandler`;
+  on success edits the draft to "✅ Создано: N сессий", on failure
+  shows retry/cancel buttons.
+- `DiscordWizardCommand.cs` — `/newsession-wizard` slash command.
+  Owner/co-GM check via `group_managers` (DiscordPermissionLookup).
+- `DiscordPermissionLookup.cs` — small DB helper that loads
+  `group_managers` rows for a guild.
+- `DiscordWizardInteractionModule.cs` — **inbound handlers** (this
+  commit). Three NetCord `ComponentInteractionModule<TContext>`
+  shells (button / StringSelectMenu / modal) share one
+  `WizardInteractionDispatcher` that:
+  1. parses the custom-id tail (`btn:choice:<step>:<value>`,
+     `btn:cancel`, `btn:back`, `btn:create`, `btn:resume:continue`,
+     `btn:resume:restart`, `select:<step>`, `modal:<step>`);
+  2. loads the active draft via
+     `IWizardDraftRepository.GetActiveAsync("Discord", ownerId, ct)`;
+  3. routes the callback through the shared
+     `GameCreationWizard.HandleInteractionAsync` (or
+     `DiscordWizardSubmitter.SubmitAsync` for the `create` button);
+  4. opens a modal popup when the new step needs text input,
+     otherwise acks with a deferred message so Discord doesn't show
+     "Application did not respond".
+
+DI / tests:
+
+- `src/GmRelay.DiscordBot/Program.cs` — 7 singleton registrations
+  (`IWizardDraftRepository`, `IWizardContextStore`, `IWizardMessenger`,
+  `GameCreationWizard`, `DiscordWizardSubmitter`,
+  `WizardInteractionDispatcher`, `DiscordWizardButtonModule`,
+  `DiscordWizardStringMenuModule`, `DiscordWizardModalModule`) plus
+  3 `AddComponentInteractions<TInteraction, TContext>` calls
+  (Button, StringMenu, Modal).
+- `tests/GmRelay.Bot.Tests/Discord/DiscordWizardInteractionModuleSourceTests.cs`
+  — 12 source-level structural smoke tests: handler classes exist,
+  all 3 derive from `ComponentInteractionModule<TContext>`, all 3
+  register `[ComponentInteraction("wizard")]`, the dispatcher
+  exposes `HandleButtonAsync` / `HandleStringMenuAsync` /
+  `HandleModalAsync`, all 5 callback kinds (`choice` / `back` /
+  `cancel` / `create` / `resume`) are routed, the dispatcher
+  invokes `GameCreationWizard.HandleInteractionAsync` and
+  `DiscordWizardSubmitter.SubmitAsync` on `create`, Program.cs
+  registers all 3 `AddComponentInteractions` and all 4 module
+  classes, draft lookup is by `GetActiveAsync("Discord", …)`, modal
+  walks `Components[0] → TextInput → .Value`, string menu reads
+  `SelectedValues[0]`.
+
+## Custom-id wire format
+
+| Interaction            | Custom-id                                | Handler                                         |
+|------------------------|------------------------------------------|-------------------------------------------------|
+| Choice button          | `wizard:btn:choice:<step>:<value>`       | Wizard's `ApplyChoice`                           |
+| Back button            | `wizard:btn:back`                        | Wizard's `ApplyBack`                             |
+| Cancel button          | `wizard:btn:cancel`                      | Wizard deletes draft + edits "❌ Мастер отменён" |
+| Create button          | `wizard:btn:create`                      | `DiscordWizardSubmitter.SubmitAsync` (3 retries) |
+| Resume: continue       | `wizard:btn:resume:continue`             | Re-render current step via messenger             |
+| Resume: restart        | `wizard:btn:resume:restart`              | Delete draft, prompt to re-run                   |
+| StringSelectMenu       | `wizard:select:<step>`                   | Wizard's `ApplyChoice` (step, SelectedValues[0]) |
+| Modal submit           | `wizard:modal:<step>`                    | Wizard's `ApplyText` (Text = Component[0].Value) |
+
+The wizard renderer (`DiscordWizardStep`) owns the prefix generation:
+`wizard:btn:<step>:<value>`, `wizard:select:<step>`,
+`wizard:modal:<step>`. The handlers match by the `wizard` prefix and
+parse the rest.
+

+
+## Open questions
+
+- ~~**Club lookup at the PickClub step**~~ — **FIXED in commit `7cfb196`.**
+  `WizardClubLookup.LoadClubsAsync` now queries `group_managers`
+  directly via injected `NpgsqlDataSource` with the same
+  `Owner | CoGm` role filter the messenger uses. The dispatcher
+  reads the owner's real club list and renders them in the
+  StringSelectMenu. Build green, 12 source-level smoke tests still
+  pass.
+- ~~**MaybeOpenModalAsync was a no-op in the previous commit**~~ — **FIXED in commit `f095209`.**
+  The dispatcher now runs the wizard first (which edits the draft
+  embed), then sends the response as either
+  `InteractionCallback.Modal(modalProperties)` (when the new step
+  needs text input) or `InteractionCallback.DeferredMessage()`
+  (otherwise). NetCord locks the response type after the first
+  `SendResponseAsync` call, so the fix is NOT to call
+  `DeferredMessage` upfront.
+- **Modal handler's free-text mapping is a hack.** Modal steps like
+  `SystemFreeText`, `DurationFreeText`, `PoolSystemDurationFreeText`
+  are mapped to the canonical wizard step (`System`, `Duration`,
+  `PoolSystemDuration`) in `MapModalStepToWizardStep`. This works
+  because the wizard's `ApplyText` dispatches on the canonical step
+  name, but a future refactor of `ApplyText` to know about the
+  free-text step names would break this. The clean fix is to add
+  dedicated "free text" steps to `WizardStepNames`.
+- **Resume:continue is a re-render, not a true resume.** The wizard
+  has no special resume case; clicking "▶️ Продолжить" just re-emits
+  the current step's embed. This is fine for the user (the embed is
+  identical to the last one they saw before the click), but the
+  underlying state isn't really "continued" — if the wizard's cleanup
+  service expired the draft between the slash command and the
+  click, the user gets a re-render of an empty step.
+- **One-draft-per-owner invariant.** The wizard's "one active draft
+  per owner" rule means a single Discord user can't run two wizard
+  sessions in parallel. Acceptable for now, but the wizard's state
+  machine doesn't enforce this — only the dispatcher does, via
+  `GetActiveAsync("Discord", ownerId)`.
+
+## Final commit history on `feat/issue-112-wizard-refactor`
+
+- `8f0f2ef` — Task 1: platform-neutral wizard refactor (core + Shared types)
+- `b81d865` — Task 2: Discord adapter scaffolding (messenger, step, submitter, command)
+- `f095209` — Task 2: interaction module + modal popup fix
+- `7cfb196` — Task 2: select/modal parser off-by-one + real club lookup

+- `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`.

+# Code review — feat/issue-112-wizard-refactor (issue #112)
+
+**Reviewer:** Verifier (mvs_86868b01387b492aae27ce6f77aca4cb)
+**Branch:** `feat/issue-112-wizard-refactor` (base `origin/main`)
+**Commits reviewed:** `8f0f2ef`, `b81d865`, `f095209`, `7cfb196`, `c4a77d3`
+**Build:** ✅ `dotnet build GM-Relay.slnx` — 0 warnings, 0 errors
+**Tests:** 580 passed / 2 skipped / 1 failed. 1 failure is the pre-existing
+`DiscordProjectStructureTests.Version_ShouldBeSynchronizedForDiscordFeatureRelease`
+(uncommitted release work in working tree, not part of this branch).
+
+## VERDICT: REQUEST_CHANGES
+
+The branch is **NOT shippable in its current state.** Every choice button
+and every "Другое…" button in the wizard is silently broken at runtime
+due to a wire-format mismatch between the renderer and the dispatcher.
+A user who clicks "D&D 5e", "Pathfinder 2e", "Waitlist вкл", "Опубликовать",
+or any "Другое… ✏️" button will see "⚠️ Неизвестная кнопка" instead of
+the wizard advancing. The 12 source-level smoke tests don't catch this
+because they only check string presence in source code, not the actual
+button-click → dispatch flow.
+
+The architecture is otherwise sound: no Telegram.Bot/NetCord leak into
+Shared, single state-machine source, all DI wired, AOT-safe, parameterized
+SQL, owner/co-GM permission check with null-safety, SecretRedactor on the
+connection string. The fix is small and surgical.
+
+---
+
+## Critical findings
+
+### C-1. Choice-button custom-id is missing the `choice:` segment — wizard is unusable end-to-end
+
+**Files:**
+- `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardStep.cs:79-80`
+- `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardInteractionModule.cs:174-226`
+
+**What's wrong.** The dispatcher's button handler matches `parts[1]`
+against `"choice"`, `"back"`, `"cancel"`, `"create"`, `"resume"`, and
+falls through to "default → Неизвестная кнопка" for anything else. The
+dispatcher's own documentation and the deliverable's wire-format table
+both agree the canonical choice-button format is
+`wizard:btn:choice:<step>:<value>`. But `ButtonCustomId` emits
+`$"wizard:btn:{step}:{value}"` — **the literal `choice:` segment is
+missing**. So clicking "D&D 5e" on the System step produces
+`wizard:btn:System:Dnd5e`, which NetCord strips the `[ComponentInteraction("wizard")]`
+prefix from, arriving at the dispatcher as `args = "btn:System:Dnd5e"` →
+`parts = ["btn", "System", "Dnd5e"]` → `parts[1] = "System"` → default
+branch → "⚠️ Неизвестная кнопка".
+
+The same bug hits:
+- `RenderType` — "Одну игру" / "Пул игр" buttons (emits
+  `wizard:btn:Type:single`, `wizard:btn:Type:pool`)
+- `RenderSystem` — D&D/Pathfinder/CoC/GURPS/Fate ("wizard:btn:System:Dnd5e" etc.)
+  **and** the "⏭ Пропустить" button (emits `wizard:btn:System:_skip`)
+- `RenderDuration` — "3 часа" / "4 часа" / "5 часов" / "6 часов" and
+  "⏭ Пропустить"
+- `RenderCapacity` / `RenderPoolSlotCapacity` — "Waitlist вкл" / "Без waitlist"
+  (emits `wizard:btn:Capacity:waitlist:on` etc.)
+- `RenderPublish` — "Опубликовать" / "Только в чате"
+- `RenderPoolAddSlots` — "Добавить слот" / "Готово, к превью"
+- `RenderPickClub` — back/cancel still work (parts[1] = "back"/"cancel")
+
+Only back, cancel, create, resume, and the "Другое… ✏️" → modal buttons
+are unaffected by *this specific* bug (see C-2 for modal buttons).
+
+The smoke test `Dispatcher_ShouldParseAllWizardActionKinds`
+(`tests/GmRelay.Bot.Tests/Discord/DiscordWizardInteractionModuleSourceTests.cs:85-97`)
+checks that the strings `"choice"`, `"back"`, `"cancel"`, `"create"`,
+`"resume"` appear in `DiscordWizardInteractionModule.cs`. It doesn't
+check the renderer's output, so the bug is invisible to the test suite.
+The same file's comment at line 69 documents the *expected* format as
+`"btn:choice:Type:single"` — which would be the correct fix.
+
+**How to fix.** Change `ButtonCustomId` in `DiscordWizardStep.cs`:
+
+```csharp
+public static string ButtonCustomId(string step, string value) =>
+    $"wizard:btn:choice:{step}:{value}";
+```
+
+This brings the renderer into alignment with the dispatcher's switch
+case `"choice"` (line 209) and with the deliverable's table at line 83.
+Re-verify with a manual click-through of every button on every step, or
+add a parser-side test (see I-3 below).
+
+### C-2. "Другое… ✏️" modal trigger buttons route to "default" instead of opening a modal
+
+**File:** `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardStep.cs:190, 206, 314`
+**Read against:** `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardInteractionModule.cs:207-226`
+
+**What's wrong.** The renderer emits modal triggers as
+`wizard:btn:modal:SystemFreeText` (the "Другое… ✏️" button on the System
+step), `wizard:btn:modal:DurationFreeText` (Duration step), and
+`wizard:btn:modal:PoolSystemDurationFreeText` (PoolSystemDuration step).
+The dispatcher's button switch handles `"choice"`, `"back"`, `"cancel"`
+but not `"modal"`. The user's click on "Другое…" hits the default branch
+and returns "⚠️ Неизвестная кнопка" — no modal pops up, the wizard
+doesn't advance. The open question in `deliverable.md:125-132` ("Modal
+handler's free-text mapping is a hack") implicitly assumes these buttons
+*work* in production, so the design intent is clear but the implementation
+didn't deliver it.
+
+**How to fix.** Add a `"modal"` case in the dispatcher's switch (between
+`"create"` and the existing branches, mirroring the "create" / "resume"
+special-case pattern):
+
+```csharp
+if (parts[1] == "modal" && parts.Length >= 3)
+{
+    var modal = DiscordWizardStep.BuildModal(parts[2], draft.ChatId);
+    if (modal is not null)
+    {
+        await context.Interaction.SendResponseAsync(InteractionCallback.Modal(modal));
+    }
+    else
+    {
+        await AckWithErrorAsync(context.Interaction, "Модал недоступен");
+    }
+    return;
+}
+```
+
+This bypasses the wizard's state machine entirely (the user's intent is
+"open a modal for free-text input", not "advance the wizard"). When the
+user submits the modal, `HandleModalAsync` will run, which already knows
+how to map `SystemFreeText` → `WizardStepNames.System` (line 453-462).
+Add a click-through test for at least one of the three steps.
+
+### C-3. `ex.Message` from `CreateSessionHandler` is shipped to the user's Discord
+
+**File:** `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardSubmitter.cs:104`
+
+**What's wrong.** On submit failure the submitter edits the draft
+message with `$"💥 Ошибка: {ex.Message}\nПопытка {payload.RetryCount}/{MaxRetries}."`
+and ships it to the user-visible draft embed. The exception originates
+in `CreateSessionHandler` which talks to PostgreSQL via Dapper. Postgres
+exception messages routinely include the constraint name, the conflicting
+key value, and sometimes the full SQL text. Even the connection-string
+DSN could leak if an `NpgsqlException` wraps a connection failure. A
+malicious user who can submit many sessions can probe DB schema and
+state by reading the error strings.
+
+**How to fix.** Log the full `ex` to the server-side log (already done
+on line 86) but show the user a generic error:
+
+```csharp
+await EditDraftMessageAsync(
+    draft,
+    $"💥 Ошибка при создании сессии. Попытка {payload.RetryCount}/{MaxRetries}. "
+    + "Попробуйте повторить или обратитесь к администратору.",
+    RetryCancelActions(),
+    ct);
+```
+
+If you want to preserve a per-error recovery hint (e.g. "Duplicate
+title — pick a different name"), map known exception types to localized
+strings; never embed the raw `ex.Message`.

+
+## Important findings
+
+### I-1. `Owner`/`CoGm` permission lookup runs on every wizard invocation, no cache
+
+**File:** `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardCommand.cs:85-87`
+
+The slash command issues an `await DiscordPermissionLookup.LoadManagerUserIdsAsync(...)`
+on every `/newsession-wizard` invocation. This is a 3-table join that
+scales linearly with the number of clubs the user manages. With a 24-hour
+draft lifetime and a single draft per owner, the same query repeats
+frequently. Not critical for the v3.8.0 release, but a 30-second in-memory
+cache would cut DB load noticeably during heavy wizard use. Same query
+shape lives in `DiscordNewSessionHandler` already (per the file comment),
+so a shared cache would benefit both.
+
+### I-2. `_skip` sentinel bypasses the wizard's own validation
+
+**File:** `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardStep.cs:191, 207`
+**Read against:** `src/GmRelay.Shared/Features/Sessions\CreateSession\Wizard\GameCreationWizard.cs:287-290`
+
+`GameCreationWizard.ApplySystemChoice` matches `"_skip"` and accepts it
+without further checks. The renderer emits `wizard:btn:System:_skip`.
+This is correct *if* the choice-button wire format gets fixed (C-1); the
+"`_skip`" string is hard-coded in the wizard and the renderer uses the
+same constant. But there's no central constant — both files have their
+own copies of the magic string. A future refactor that renames the
+sentinel in one place will silently break the other. Suggest
+`public const string SkipSentinel = "_skip"` on a shared class.
+
+### I-3. Smoke tests are string-matching only — no behaviour coverage of the adapter
+
+**File:** `tests/GmRelay.Bot.Tests/Discord/DiscordWizardInteractionModuleSourceTests.cs`
+
+All 12 smoke tests in this file are `Assert.Contains` against the
+source text. They would all pass against a file full of `// choice`
+comments and dead code. The test class header at line 8-17 acknowledges
+this ("smoke gate"), and the broader Wizard test suite
+(`tests/GmRelay.Bot.Tests/Features/Sessions/CreateSession/Wizard/`) does
+exercise the platform-neutral state machine — but the *adapter* (the
+mapping from `ButtonInteractionContext` → `_wizard.HandleInteractionAsync`)
+has zero behavioural coverage. C-1 and C-2 both bypass the entire
+smoke-test surface.
+
+Minimum bar to add: a parser-roundtrip test that takes the renderer's
+output for each `RenderX()` step and feeds it through the dispatcher's
+button handler to verify it doesn't fall into the default branch. Even
+a hand-rolled `ButtonInteractionContext` fake (or a helper that mimics
+the dispatcher's `args.Split(':', 4)` parser) would catch both bugs.
+Cost: ~50 lines; payoff: catches the entire class of "renderer and
+dispatcher disagree on the wire format" regressions.
+
+### I-4. `AddComponentInteractions<TInteraction, TContext>` is called for Modal but the renderer relies on `Label → TextInput` layout
+
+**File:** `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardStep.cs:436-444`
+**Read against:** `DiscordWizardInteractionModule.cs:440-451`
+
+`BuildModal` always wraps a single `TextInput` in a `Label` (Discord's
+`IModalComponentProperties` API requires labels). The dispatcher reads
+`Components[0]` and assumes it is a `Label` (line 446). This is
+consistent *today*, but if a future step needs two inputs in one
+modal, the extraction logic needs to walk all components, not just
+`[0]`. Document the constraint on the dispatcher's
+`ExtractModalText` method ("current contract: exactly one Label,
+one TextInput") and the renderer's `BuildModal` ("emits one
+Label+TextInput, no exceptions").
+
+### I-5. The 3-retry counter is bound to the in-memory `WizardPayload`, not the DB row
+
+**File:** `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardSubmitter.cs:86-89`
+
+`payload.RetryCount += 1; SavePayload(draft, payload);` is called *before*
+the `if (payload.RetryCount >= MaxRetries)` check. The counter is
+serialized into `draft.PayloadJson` and re-loaded on the next click, so
+the bound is correct across bot restarts. However, the in-memory
+`draft` object is shared with the dispatcher's `_wizard` after
+`HandleInteractionAsync` returns, and a future refactor that pulls the
+payload from the DB instead of the in-memory copy could see a stale
+count. Document the invariant: "RetryCount is read from the in-memory
+payload after this line; do not re-load from DB before the comparison."
+
+### I-6. `BuildResumeRow` re-uses the same customId suffix scheme as the in-wizard buttons
+
+**File:** `src/GmRelay.DiscordBot/Features/Sessions/Wizard/DiscordWizardCommand.cs:193-209`
+
+`BuildResumeRow` emits three buttons:
+- "▶️ Продолжить" → `wizard:btn:resume:continue` ✓ (works)
+- "🔄 Заново" → `wizard:btn:resume:restart` ✓ (works)
+- "❌ Отмена" → `wizard:btn:cancel:1` (uses `DiscordWizardStep.ButtonCustomId("cancel", "1")`)
+
+The cancel button relies on the dispatcher's `parts[1] == "cancel"`
+match. With C-1 fixed, this still works because cancel is in the
+switch, not the new "choice" path. But the `ButtonCustomId` signature
+will change semantics after C-1: it will become
+`$"wizard:btn:choice:{step}:{value}"`. `BuildResumeRow` passing
+`"cancel"` as the step will then produce `wizard:btn:choice:cancel:1`,
+which the dispatcher's switch will not match (no `"choice"` in the
+parts). Fix C-1 must update `BuildResumeRow` to emit
+`wizard:btn:cancel:1` directly (not via `ButtonCustomId`).
+
+---
+
+## Nits
+
+- `DiscordWizardInteractionModule.cs:308, 357` — the select and modal
+  handlers split args with `Split(':', 2)` (max 2 parts), while the
+  button handler uses `Split(':', 4)` (max 4 parts). Inconsistent. The
+  net effect is correct (select has 2 segments, modal has 2, button has
+  2–4), but a comment explaining the max-count rationale would help.
+- `DiscordWizardStep.cs:74` — `throw new InvalidOperationException` on
+  unknown step is fine for now, but a future maintainer adding a step
+  to `WizardStepNames` will get a runtime exception. A `switch` exhaustiveness
+  check (e.g. a private static assert in tests) would catch this at
+  build time.
+- `DiscordPermissionLookup.cs:28-30` — `g.platform = 'Discord'` is
+  hard-coded in the SQL. A `g.platform = @Platform` parameter would
+  mirror the dispatcher's parameterized style and make the helper
+  reusable for any future platform. Not blocking.
+- `DiscordWizardCommand.cs:72-81` — fetching the guild via REST inside
+  the slash command costs an extra round-trip. The
+  `resolvedPermissions` from the interaction already includes
+  `Administrator`; only the "guild owner" case needs the REST call.
+  Consider short-circuiting when `(resolvedPermissions & Administrator)
+  != 0`.
+- `DiscordWizardMessenger.cs:188-192` — hard-coded
+  `new Color(0x5865F2)` (Discord blurple). Extracting to a const
+  `WizardEmbedColor` would let the Web/Telegram versions use the same
+  brand color if they ever render wizards.
+
+---
+
+## Migration V032 sanity check
+
+**File:** `src/GmRelay.Bot/Migrations/V032__wizard_drafts_platform.sql`
+
+- Line 8-9 `ADD COLUMN platform TEXT NOT NULL DEFAULT 'Telegram'`
+  — DEFAULT literal makes this O(1) on PostgreSQL ≥ 11. Safe on
+  existing rows.
+- Lines 13-30 — `ALTER COLUMN ... TYPE TEXT USING ...::TEXT` on the
+  `chat_id`, `message_thread_id`, `draft_message_id`, and renamed
+  `owner_id` columns. All conversions are lossless
+  (BIGINT → decimal-string, INT → decimal-string). Safe.
+- Line 26-27 `RENAME COLUMN owner_telegram_id TO owner_id` — the
+  rename happens mid-migration. Any DML hitting the table
+  concurrently that uses the old name will fail. For a bot that
+  processes both Telegram and Discord traffic, this is a brief
+  exclusivity lock. Consider splitting into two migrations
+  (rename + new index, then type change) so each lock is shorter.
+  Not blocking for v3.8.0, but document the brief lock window.
+
+No DEFAULT-cascade issue, no NOT NULL on existing-row failure. The
+deliverable's "Will this fail on existing rows?" question gets a
+"no, but plan a maintenance window" answer.
+
+---
+
+## Architecture sanity (re-confirmed)
+
+- `src/GmRelay.Shared/` — only references to Telegram.Bot/NetCord are
+  in doc comments warning the developer not to add them. csproj has
+  no Telegram.Bot or NetCord package references. `GameCreationWizard`,
+  `IWizardMessenger`, `WizardCallbackData`, `WizardStepLimits`,
+  `WizardStepNames`, `WizardPayload`, `WizardDraft` are all in exactly
+  one place (Shared). ✓
+- `src/GmRelay.DiscordBot/Program.cs:87-102` — all 7 wizard services
+  registered as singleton. All 3 `AddComponentInteractions<...>`
+  calls present (Button, StringMenu, Modal). All 4 module/dispatcher
+  classes (`WizardInteractionDispatcher`, `DiscordWizardButtonModule`,
+  `DiscordWizardStringMenuModule`, `DiscordWizardModalModule`)
+  registered. ✓
+- AOT-safety: no `System.Reflection`, no `dynamic`, no
+  `Activator.CreateInstance`, no `Type.GetType` in the new Discord
+  or Shared code. ✓
+- `DiscordPermissionLookup.cs:23-31` and
+  `DiscordWizardMessenger.cs:154-165` and the inline
+  `WizardClubLookup` in `DiscordWizardInteractionModule.cs:508-519`
+  all use parameterized queries (`@GuildId`, `@Platform`,
+  `@ExternalId`, `@OwnerId`). No SQL string interpolation. ✓
+- `Program.cs:54` — `SecretRedactor.RedactConnectionString` on the
+  startup log. ✓
+- `DiscordWizardCommand.cs:51-94` — DM invocations rejected
+  (`GuildId` null check), channel null-checked, member type-checked
+  via `as GuildInteractionUser`, owner/admin/DB-manager permission
+  check via `DiscordPermissionChecker.CanManageSchedule`. No NRE
+  on `Context.User`. ✓
+
+---
+
+## Summary
+
+Strong foundation: the platform-neutral refactor is well-executed, the
+state machine has solid test coverage, the Discord adapter's DI graph
+is clean, and security primitives (parameterized SQL, permission check,
+secret redaction) are in place. But the Discord adapter's runtime path
+is untested, and a single oversight in the renderer's button custom-id
+format (missing the `choice:` segment) breaks every choice button in
+the wizard at click time. The "Другое… ✏️" modal triggers are also
+unrouted in the dispatcher, leaving the free-text input path
+unreachable. The 3-attempt finalize loop works but leaks `ex.Message`
+to the user. After fixing C-1 / C-2 / C-3, adding I-3 (behavioural
+test of the adapter), and re-running the manual click-through checklist
+(System → Duration → DateTime → Capacity → Visibility → Publish →
+Confirm for Single; full pool flow), this branch is ready to merge.

+# 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
+
+### Migration V029
+
+Create `src/GmRelay.Bot/Migrations/V029__add_completed_game_portfolios_and_reviews.sql`.
+
+### `portfolio_games`
+
+| Column | Type | Constraints | Description |
+|---|---|---|---|
+| `id` | `UUID` | primary key, generated | Adventure identifier |
+| `group_id` | `UUID` | not null, FK to `game_groups(id)` with cascade delete | Owning club |
+| `public_slug` | `VARCHAR(160)` | unique case-insensitive when non-null | Public route segment |
+| `title` | `VARCHAR(255)` | not null | Adventure title |
+| `description` | `TEXT` | nullable for drafts | Public description |
+| `cover_storage_key` | `TEXT` | nullable for drafts | Storage-provider-neutral cover key |
+| `system` | `VARCHAR(50)` | nullable | Game system |
+| `format` | `VARCHAR(20)` | nullable, checked against `Online`, `Offline`, `Hybrid` | Play format |
+| `completed_at` | `TIMESTAMPTZ` | not null | Portfolio ordering date |
+| `is_public` | `BOOLEAN` | not null, default false | Public visibility |
+| `published_at` | `TIMESTAMPTZ` | nullable | First publication timestamp |
+| `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`
+
+| Column | Type | Constraints | Description |
+|---|---|---|---|

+
+Constraints and indexes:
+
+```sql
+CHECK (moderation_status IN ('Pending', 'Approved', 'Rejected', 'Hidden'))
+UNIQUE (portfolio_game_id, author_player_id)
+```
+
+- Author lookup index `ix_portfolio_game_reviews_author` on `(author_player_id)`.
+- Partial moderator lookup index `ix_portfolio_game_reviews_moderator` on `(moderated_by_player_id)` where `moderated_by_player_id IS NOT NULL`.
+- Partial public index on `(portfolio_game_id, created_at DESC)` where `moderation_status = 'Approved'` and `publication_consent_at IS NOT NULL`.
+- Partial moderation index on `(portfolio_game_id, created_at DESC)` where `moderation_status = 'Pending'`.
+

+
+## Cover Storage
+
+### Contract
+
+Add a small storage abstraction:
+
+```csharp
+public interface IPortfolioCoverStorage
+{
+    Task<PortfolioCoverUploadResult> SaveAsync(
+        Stream content,
+        string contentType,
+        CancellationToken cancellationToken = default);
+
+    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.
