Merge pull request #119 : feat(web): private club showcases with membership flow (v3.7.0, issue #110 )

fix(web): allow cancelling pending applications; drop contradictory message guard
Address review feedback from PR #119: - LeaveClubMembershipAsync: was rejecting Pending rows because the SQL required status = 'Active', so clicking "Отозвать заявку" on a Pending membership surfaced a misleading "Active membership X not found" InvalidOperationException. Now the method first tries Active -> Left and falls back to Pending -> Rejected so the same UI flow covers both states. - PublicClub.razor TrySubmitApplicationAsync: removed the empty-input guard that contradicted the "(необязательно)" label and the server side (AuthorizedMembershipService already trims and accepts null). No tests broken (493 still passing), no public-API changes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

+## 📚 Портфолио завершённых приключений
+
+Начиная с **v3.6.0** ГМы могут публиковать завершённые кампании в виде постоянных портфолио-страниц с обложкой, описанием, системой/форматом, составом мастеров и модерируемыми отзывами игроков.
+
+### Возможности
+
+- **Управление портфолио** — в `/group/{id}/portfolio` владелец и co-GM создают портфолио-игры из прошедших сессий, выбирают мастеров, заполняют описание, загружают обложку и публикуют по `public_slug`.
+- **Публичная страница `/portfolio/{slug}`** — read-only карточка приключения с обложкой, описанием, составом мастеров (только публичные профили) и одобренными отзывами.
+- **Отзывы участников** — на `/portfolio/{slug}/review` аутентифицированные игроки, чьи идентификаторы участвовали в одной из привязанных сессий без пометки GM, отправляют отзыв с явным согласием на публикацию; один отзыв на игрока, повторная отправка запрещена.
+- **Модерация отзывов** — на странице редактора портфолио владелец/co-GM видит очередь `Pending` и переводит отзывы в `Approved`, `Rejected` или `Hidden`; только `Approved` отзывы попадают в публичную выдачу.
+- **Публикация под требования** — портфолио-игра публикуется только при заполненном slug, описании, обложке, минимум одной завершённой сессии и хотя бы одном мастере группы.
+
+### Хранение обложек
+
+Загруженные обложки хранятся в Docker volume `portfolio_covers` (по умолчанию имя `gmrelay_portfolio_covers`), обслуживаются веб-приложением по пути `/portfolio-covers/{storageKey}` с кешированием `Cache-Control: public, max-age=31536000, immutable`.
+
+В `.env` можно переопределить имя volume:
+
+```env
+PORTFOLIO_COVERS_VOLUME_NAME=gmrelay_portfolio_covers
+```
+
+В `compose.yaml` это значение пробрасывается в сервис `web` через `volumes.portfolio_covers.name`; путь к каталогу внутри контейнера — `/app/portfolio-covers` (настраивается через `PortfolioCovers__StoragePath`).
+
+Хранилище инкапсулировано интерфейсом `IPortfolioCoverStorage` с реализацией `LocalPortfolioCoverStorage` (файловая система), что оставляет границу для замены на S3-совместимое хранилище без изменения кода портфолио-сервисов.

+- `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`.

+# 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')),

+
+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

+# 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 |
+|---|---|---|---|
+| `portfolio_game_id` | `UUID` | not null, FK to `portfolio_games(id)` with cascade delete | Adventure |
+| `player_id` | `UUID` | not null, FK to `players(id)` with cascade delete | Displayed GM |
+
+Primary key: `(portfolio_game_id, player_id)`.
+
+Add an index on `(player_id, portfolio_game_id)` for public GM profile reads.
+
+### `portfolio_game_reviews`
+
+| Column | Type | Constraints | Description |
+|---|---|---|---|
+| `id` | `UUID` | primary key, generated | Review identifier |
+| `portfolio_game_id` | `UUID` | not null, FK to `portfolio_games(id)` with cascade delete | Adventure |
+| `author_player_id` | `UUID` | not null, FK to `players(id)` with cascade delete | Private author reference |
+| `author_display_name` | `VARCHAR(255)` | not null | Public snapshot |
+| `body` | `TEXT` | not null | Review text |
+| `publication_consent_at` | `TIMESTAMPTZ` | not null | Player consent timestamp |
+| `moderation_status` | `VARCHAR(20)` | not null, default `Pending`, checked | Moderation state |
+| `moderated_by_player_id` | `UUID` | nullable, FK to `players(id)` with set null on delete | Private moderator reference |
+| `moderated_at` | `TIMESTAMPTZ` | nullable | Moderation timestamp |
+| `created_at` | `TIMESTAMPTZ` | not null, default now | Audit timestamp |
+| `updated_at` | `TIMESTAMPTZ` | not null, default now | Audit timestamp |
+
+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`
