Merge pull request 'Add organizer-only attendee list (011)' (#20) from 011-view-attendee-list into master

New GET /events/{token}/attendees endpoint returns attendee names when
a valid organizer token is provided (403 otherwise). The frontend
conditionally renders the list below the attendee count for organizers,
silently degrading for visitors.

+description: Create a Gitea pull request, monitor CI pipeline status, and merge when green. Use this skill when the user asks to "create a PR", "merge the PR", "ship it", "make it ready to merge", or when you need to open a pull request and wait for CI before merging. Also use when asked to check CI/PR status on Gitea.
+---
+
+# Merge PR
+
+Create a pull request on Gitea, monitor the CI pipeline via the Actions API, and merge once all jobs pass.
+
+## Why this skill exists
+
+The Gitea MCP pull request API does not return CI status directly. To know if a PR is ready to merge, you must cross-reference the PR's `head.sha` with the Actions runs API, find the matching run, and check job conclusions. This skill encodes that workflow so it doesn't have to be rediscovered.
+
+## Prerequisites
+
+The Gitea MCP tools must be available. The key tools are:
+
+- `mcp__gitea__pull_request_write` (method: `create`, `merge`)
+- `mcp__gitea__pull_request_read` (method: `get`)
+- `mcp__gitea__actions_run_read` (methods: `list_runs`, `list_run_jobs`)
+
+If these tools are not yet loaded, use ToolSearch to discover and load them before proceeding.
+
+## Workflow
+
+### 1. Create the PR
+
+Use `mcp__gitea__pull_request_write` with method `create`. Include a clear title, body with summary and test plan, head branch, and base branch (usually `master`).
+
+Save the returned `head.sha` — you need it to find the CI run.
+
+### 2. Find the CI run for the PR
+
+The Actions API has no direct "get CI status for PR" call. Instead:
+
+```
+mcp__gitea__actions_run_read(method: "list_runs", owner, repo, perPage: 5)
+```
+
+Find the run whose `head_sha` matches the PR's `head.sha`. This is the CI run triggered by the push that the PR points to. If the branch was force-pushed or new commits were added, always match against the latest `head.sha` from a fresh `get` on the PR.
+
+### 3. Monitor job status
+
+Once you have the run ID:
+
+```
+mcp__gitea__actions_run_read(method: "list_run_jobs", owner, repo, run_id: <id>)
+```
+
+This returns all jobs with their `status` (queued/in_progress/completed) and `conclusion` (success/failure/skipped/null).
+
+Present a status table to the user:
+
+| Job | Status |
+|-----|--------|
+| backend-test | success |
+| frontend-test | in_progress |
+| frontend-e2e | queued |
+
+If jobs are still running, wait ~30 seconds and check again. Don't poll in a tight loop.
+
+### 4. Handle failures
+
+If any job has `conclusion: failure`:
+- Use `mcp__gitea__actions_run_read` with method `get_job_log_preview` to fetch the failing job's log
+- Report the failure to the user with relevant log output
+- Do NOT attempt to merge
+
+### 5. Merge when green
+
+Once all jobs show `conclusion: success` (or `skipped` for conditional jobs like `build-and-publish`):
+
+```
+mcp__gitea__pull_request_write(
+  method: "merge",
+  owner, repo,
+  index: <pr_number>,
+  merge_style: "merge",
+  delete_branch: true
+)
+```
+
+Ask the user for confirmation before merging. They may want to review the PR in the web UI first.
+
+### 6. Post-merge cleanup
+
+After a successful merge, suggest:
+- `git checkout master && git pull origin master`
+- `git branch -d <feature-branch>` (local cleanup)
+- Tagging a release if appropriate (see `/release` skill)
+
+## Abbreviated flow
+
+When the user just wants a quick status check (e.g. "how's the PR?"), skip straight to steps 2-3: find the run by SHA, show the job status table.

+* Scheduled Job oder Lazy Cleanup bei Zugriff
+* Löscht Event, RSVPs, Updates, Bilder, Metadaten
+* Idempotent, kein PII im Log

+* Nur nicht-abgelaufene Events zählen
+* Unset/leer = unbegrenzt
+* Serverseitige Durchsetzung bei Event-Erstellung

+### 020 – PWA
+Web App Manifest + Service Worker für Installierbarkeit und Offline-Caching.
+* Standalone-Modus ohne Browser-Chrome
+* Icon + Name auf Home-Screen
+* Alle Assets selbstgehostet
+
+### 021 – Farbthemen
+Organisator wählt bei Erstellung ein vordefiniertes Farbthema für die Event-Seite.
+* Nur auf der Gast-Seite angewendet (nicht global)
+* Änderbar beim Bearbeiten
+* Unabhängig von Dark/Light Mode
+
+### 022 – Headerbild
+Organisator sucht Headerbild über integrierte Unsplash-Suche.
+* Serverseitig geproxied (Client kontaktiert nie Unsplash)
+* Bild lokal gespeichert + Unsplash-Attribution
+* Feature deaktiviert wenn kein API-Key konfiguriert
+
+### 023 – Dark Mode
+App erkennt `prefers-color-scheme` und bietet manuellen Toggle.
+* Manuelle Auswahl in localStorage gespeichert
+* Gilt für globales App-Chrome, nicht Event-Farbthemen
+* Beide Modi WCAG AA konform
+
+### 024 – Event absagen
+Organisator kann Event absagen (mit optionaler Nachricht, Einweg-Transition).
+* RSVPs werden nach Absage abgelehnt
+* Absage-Nachricht nachträglich editierbar
+* Kann nicht rückgängig gemacht werden
+
+### 025 – Event löschen
+Organisator löscht Event permanent und unwiderruflich.
+* Entfernt alle zugehörigen Daten sofort

+* Funktioniert in jedem Event-Status
+
+### 026 – 404-Seite
+Catch-all Route für ungültige Pfade mit "Seite nicht gefunden" und Link zur Startseite.
+* Folgt dem Design System (Electric Dusk + Sora)

+# Implementation Plan: View Event Landing Page
+
+**Branch**: `007-view-event` | **Date**: 2026-03-06 | **Spec**: [spec.md](spec.md)
+**Input**: Feature specification from `/specs/007-view-event/spec.md`
+
+## Summary
+
+Add a public event detail page at `/events/:token` that displays event information (title, date/time with IANA timezone, description, location, attendee count) without requiring authentication. The page handles four states: loaded, expired ("event has ended"), not found (404), and server error (retry button). Loading uses skeleton-shimmer placeholders. Backend adds `GET /events/{token}` endpoint and a `timezone` field to the Event model (cross-cutting change to US-1).
+
+## Technical Context
+
+**Language/Version**: Java 25 (backend), TypeScript 5.9 (frontend)
+**Primary Dependencies**: Spring Boot 3.5.x, Vue 3, Vue Router 5, openapi-fetch, openapi-typescript
+**Storage**: PostgreSQL (JPA via Spring Data, Liquibase migrations)
+**Testing**: JUnit (backend), Vitest (frontend unit), Playwright + MSW (frontend E2E)
+**Target Platform**: Self-hosted web application (Docker)
+**Project Type**: Web service + SPA
+**Performance Goals**: N/A (single-user scale, self-hosted)
+**Constraints**: No external resources (CDNs, fonts, tracking), WCAG AA, privacy-first
+**Scale/Scope**: Single new view + one new API endpoint + one cross-cutting model change
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| I. Privacy by Design | PASS | No PII exposed. Only attendee count shown (not names). No external resources. No tracking. |
+| II. Test-Driven Methodology | PASS | TDD enforced: backend unit tests, frontend unit tests, E2E tests per spec. |
+| III. API-First Development | PASS | OpenAPI spec updated first. Types generated. Response schemas include `example:` fields. |
+| IV. Simplicity & Quality | PASS | Minimal changes: one GET endpoint, one new view, one model field. `attendeeCount` returns 0 (no RSVP stub). Cancelled state deferred. |
+| V. Dependency Discipline | PASS | No new dependencies. Skeleton shimmer is CSS-only. |
+| VI. Accessibility | PASS | Semantic HTML, ARIA attributes, keyboard navigable, WCAG AA contrast via design system. |
+
+**Post-Phase-1 re-check**: All gates still pass. The `timezone` field addition is a justified cross-cutting change documented in research.md R-1.

+# Quickstart: View Event Landing Page (007)
+
+## What this feature does
+
+Adds a public event detail page at `/events/:token`. Guests open a shared link and see:
+- Event title, date/time (with IANA timezone), description, location
+- Count of confirmed attendees (no names)
+- "Event has ended" state for expired events
+- "Event not found" for invalid tokens
+- Skeleton shimmer while loading
+
+## Prerequisites
+
+- US-1 (Create Event) is implemented — Event entity, JPA persistence, POST endpoint exist.
+- No RSVP model yet — attendee count returns 0 until RSVP feature is built.
+
+## Key changes
+
+### Backend
+
+1. **OpenAPI**: Add `GET /events/{token}` endpoint + `GetEventResponse` schema. Add `timezone` field to `CreateEventRequest`, `CreateEventResponse`, and `GetEventResponse`.
+2. **Domain**: Add `timezone` (String) to `Event.java`.
+3. **Persistence**: Add `timezone` column to `EventJpaEntity`, Liquibase migration.
+4. **Use case**: New `GetEventUseCase` (inbound port) + implementation in `EventService`.
+5. **Controller**: `EventController` implements `getEvent()` — maps to `GetEventResponse`, computes `expired` and `attendeeCount`.
+
+### Frontend
+
+1. **API types**: Regenerate `schema.d.ts` from updated OpenAPI spec.
+2. **EventDetailView.vue**: New view component — fetches event by token, renders detail card.
+3. **Router**: Replace `EventStubView` import at `/events/:token` with `EventDetailView`.
+4. **States**: Loading (skeleton shimmer), loaded, expired, not-found, server-error (retry button).
+5. **Create form**: Send `timezone` field (auto-detected via `Intl.DateTimeFormat`).
+
+### Testing
+
+- Backend: Unit tests for `GetEventUseCase`, controller tests for GET endpoint (200, 404).
+- Frontend: Unit tests for EventDetailView (all states).
+- E2E: Playwright tests with MSW mocks for all states (loaded, expired, not-found, error).

+# Research: View Event Landing Page (007)
+
+**Date**: 2026-03-06 | **Status**: Complete
+
+## R-1: Timezone Field (Cross-Cutting)
+
+**Decision**: Add `timezone` String field (IANA zone ID) to Event entity, JPA entity, and OpenAPI schemas (both Create and Get).
+
+**Rationale**: The spec requires displaying the IANA timezone name (e.g. "Europe/Berlin") alongside the event time. `OffsetDateTime` preserves the offset (e.g. `+01:00`) but loses the IANA zone name. Since Europe/Berlin and Africa/Lagos both use `+01:00`, the zone name must be stored separately.
+
+**Alternatives considered**:
+- Store `ZonedDateTime` instead of `OffsetDateTime` — rejected because `OffsetDateTime` is already the established type in the stack (see `datetime-best-practices.md`), and `ZonedDateTime` serialization is non-standard in JSON/OpenAPI.
+- Derive timezone from offset — rejected because offset-to-zone mapping is ambiguous.
+
+**Impact on US-1 (Create Event)**:
+- `CreateEventRequest` gains a required `timezone` field (string, IANA zone ID).
+- `CreateEventResponse` gains a `timezone` field.
+- Frontend auto-detects via `Intl.DateTimeFormat().resolvedOptions().timeZone`.
+- Backend validates against `java.time.ZoneId.getAvailableZoneIds()`.
+- JPA: new `VARCHAR(64)` column `timezone` on `events` table.
+- Liquibase changeset: add `timezone` column. Existing events without timezone get `UTC` as default (pre-launch, destructive migration acceptable).
+
+## R-2: GET Endpoint Design
+
+**Decision**: `GET /api/events/{token}` returns public event data. Uses the existing hexagonal architecture pattern.
+
+**Rationale**: Follows the established pattern from `POST /events`. The event token is the public identifier — no auth required.
+
+**Flow**:
+1. `EventController` implements generated `EventsApi.getEvent()`.
+2. New inbound port: `GetEventUseCase` with `getByEventToken(UUID): Optional<Event>`.
+3. `EventService` implements the use case, delegates to `EventRepository.findByEventToken()` (already exists).
+4. Controller maps domain `Event` to `GetEventResponse` DTO.
+5. 404 returns `ProblemDetail` (RFC 9457) — no event data leaked.
+
+**Alternatives considered**:
+- Separate `/event/{token}` path (singular) — rejected because OpenAPI groups by resource; `/events/{token}` is RESTful convention.
+- Note: Frontend route is `/event/:token` (spec clarification), but API path is `/api/events/{token}`. These are independent.
+
+## R-3: Attendee Count Without RSVP Model
+
+**Decision**: Include `attendeeCount` (integer) in the `GetEventResponse`. Return `0` until the RSVP feature (US-8+) is implemented.
+
+**Rationale**: FR-001 requires attendee count display. The API contract should be stable from the start — consumers should not need to change when RSVP is added later. Returning `0` is correct (no RSVPs exist yet).
+
+**Future hook**: When RSVP is implemented, `EventService` or a dedicated query will `COUNT(*) WHERE event_id = ? AND status = 'ATTENDING'`.
+
+**Alternatives considered**:
+- Omit `attendeeCount` until RSVP exists — rejected because it would require API consumers to handle the field's absence, then handle its presence later. Breaking change.
+- Add a stub RSVP table now — rejected (YAGNI, violates Principle IV).
+
+## R-4: Expired Event Detection
+
+**Decision**: Server-side. The `GetEventResponse` includes a boolean `expired` field, computed by comparing `expiryDate` with the server's current date.
+
+**Rationale**: Server is the source of truth for time. Client clocks may be wrong. The frontend uses this flag to toggle the "event has ended" state.
+
+**Computation**: `event.getExpiryDate().isBefore(LocalDate.now(clock))` — uses the injected `Clock` bean (already exists for testability in `EventService`).
+
+**Alternatives considered**:
+- Client-side comparison — rejected because client clock may differ from server, leading to inconsistent behavior.
+- Separate endpoint for status — rejected (over-engineering).
+
+## R-5: URL Pattern
+
+**Decision**: Frontend route stays at `/events/:token` (plural). API path is `/api/events/{token}`. Both use the plural RESTful convention consistently.
+
+**Rationale**: `/events/:token` is the standard REST resource pattern (collection + identifier). The existing router already uses this path. Consistency between frontend route and API resource name reduces cognitive overhead.
+
+**Impact**: No route change needed — the existing `/events/:token` route in the router is correct.
+
+## R-6: Skeleton Shimmer Loading State
+
+**Decision**: CSS-only shimmer animation using a gradient sweep. No additional dependencies.
+
+**Rationale**: The spec requires skeleton-shimmer placeholders during API loading. A CSS-only approach is lightweight and matches the dependency discipline principle.
+
+**Implementation pattern**:
+```css
+.skeleton {
+  background: linear-gradient(90deg, var(--color-card) 25%, #e0e0e0 50%, var(--color-card) 75%);
+  background-size: 200% 100%;
+  animation: shimmer 1.5s infinite;
+  border-radius: var(--radius-card);
+}
+@keyframes shimmer {
+  0% { background-position: 200% 0; }
+  100% { background-position: -200% 0; }
+}
+```
+
+Skeleton blocks match the approximate shape/size of the real content fields (title, date, location, etc.).
+
+## R-7: Cancelled Event State (Deferred)
+
+**Decision**: The `GetEventResponse` does NOT include cancellation fields yet. US-3 (view cancelled event) is explicitly deferred until US-18 (cancel event) is implemented.
+
+**Rationale**: Spec says "[Deferred until US-18 is implemented]". Adding unused fields violates Principle IV (KISS).
+
+**Future hook**: When US-18 lands, add `cancelled: boolean` and `cancellationMessage: string` to the response schema.

+- **Event**: Has a public event token (UUID in URL), title, optional description, date/time (OffsetDateTime — displayed in the organizer's original timezone, no conversion to viewer timezone), IANA timezone name (e.g. `Europe/Berlin`, stored as separate field — required for human-readable timezone display), optional location, expiry date (LocalDate), and optionally a cancelled state with message. See `.specify/memory/research/datetime-best-practices.md` for full stack type mapping.
-- **RSVP**: Has a guest name and attending status; confirmed attendees (status = attending) are listed on the public event page.
+  - **Note**: The IANA timezone requires a new `timezone` field on the Event entity and API schema. This impacts US-1 (Create Event) — the frontend must send the organizer's IANA zone ID alongside the OffsetDateTime.

 ### Measurable Outcomes
 
 - **SC-001**: A guest who opens a valid event URL can see all set event fields (title, date/time, and any optional fields) without logging in.

+- **SC-002**: The attendee count reflects all current server-side RSVPs with attending status. No individual names are exposed on the public event page.
 - **SC-003**: An expired event URL renders the "ended" state — RSVP controls are absent from the DOM, not merely hidden via CSS.
 - **SC-004**: An unknown event token URL renders a "not found" message — no event data, no server error details.
 - **SC-005**: No network requests to external domains are made when loading the event page.

+## Clarifications
+
+### Session 2026-03-06
+
+- Q: What should the event page display when the server is temporarily unavailable? → A: Generic friendly error state with a manual "Retry" button; no automatic retry.
+- Q: How should date/time be displayed regarding timezones? → A: Organizer timezone preserved — display the time exactly as entered by the organizer (OffsetDateTime), no conversion to viewer's local timezone. The IANA timezone name (e.g. "Europe/Berlin") MUST be displayed alongside the time. Requires a new `timezone` field on Event entity/API (impacts US-1).
+- Q: What is the URL pattern for event pages? → A: `/events/:token` (e.g. `/events/a1b2c3d4-...`). Plural, matching the RESTful API resource name.
+- Q: Should guest names be visible to other guests on the public event page? → A: No. Only the attendee count is shown to guests. Individual names are exclusively visible to the organizer, sorted alphabetically.
+- Q: How should the loading state look while the API call is in progress? → A: Skeleton-shimmer (placeholder blocks in field shape that shimmer until data arrives).
+- Q: Should the event page include OpenGraph meta tags for link previews? → A: Out of scope for US-007. Separate user story — generic app-branding OG-tags only, no event data exposed to crawlers. Noted in `.specify/memory/ideen.md`.
+- Q: Should date/time formatting adapt to the viewer's browser locale? → A: Yes, browser-locale-based via `Intl.DateTimeFormat` (e.g. DE: "15. März 2026, 20:00" / EN: "March 15, 2026, 8:00 PM").
+- Q: Is RSVP status binary or are there more states (e.g. "maybe")? → A: Binary — attending or not attending. No "maybe" status. Count reflects only confirmed attendees.

+# Tasks: View Event Landing Page
+
+**Input**: Design documents from `/specs/007-view-event/`
+**Prerequisites**: plan.md, spec.md, research.md, data-model.md, contracts/get-event.yaml
+
+**Tests**: Included — constitution enforces Test-Driven Methodology (Principle II).
+
+**Organization**: Tasks grouped by user story. US3 (cancelled event) is deferred until US-18.
+
+## Format: `[ID] [P?] [Story] Description`
+
+- **[P]**: Can run in parallel (different files, no dependencies)
+- **[Story]**: Which user story this task belongs to (e.g., US1, US2, US4)
+- Exact file paths included in descriptions
+
+---
+
+## Phase 1: Setup (Cross-Cutting Schema Changes)
+
+**Purpose**: OpenAPI contract update, database migration, and type generation — prerequisites for all backend and frontend work.
+
+- [x] T001 Update OpenAPI spec: add `GET /events/{token}` endpoint, `GetEventResponse` schema, and `timezone` field to `CreateEventRequest`/`CreateEventResponse` in `backend/src/main/resources/openapi/api.yaml`
+- [x] T002 [P] Add Liquibase changeset: `timezone VARCHAR(64) NOT NULL DEFAULT 'UTC'` column on `events` table in `backend/src/main/resources/db/changelog/`
+- [x] T003 Regenerate frontend TypeScript types from updated OpenAPI spec in `frontend/src/api/schema.d.ts`
+
+**Checkpoint**: OpenAPI contract finalized, DB schema ready, frontend types available.
+
+---
+
+## Phase 2: Foundational (Backend — Blocks All User Stories)
+
+**Purpose**: Domain model update, new GET use case, controller endpoint, and backend tests. All user stories depend on this.
+
+**CRITICAL**: No frontend user story work can begin until this phase is complete.
+
+### Backend Tests (TDD — write first, verify they fail)
+
+- [x] T004 [P] Backend unit tests for `GetEventUseCase`: test getByEventToken returns event, returns empty for unknown token, computes expired flag — in `backend/src/test/java/de/fete/`
+- [x] T005 [P] Backend controller tests for `GET /events/{token}`: test 200 with full response, 200 with optional fields absent, 404 with ProblemDetail — in `backend/src/test/java/de/fete/`
+- [x] T006 [P] Backend tests for timezone in Create Event flow: request validation (valid/invalid IANA zone), persistence round-trip — in `backend/src/test/java/de/fete/`
+
+### Backend Implementation
+
+- [x] T007 Add `timezone` field (String) to domain model in `backend/src/main/java/de/fete/domain/model/Event.java`
+- [x] T008 [P] Add `timezone` column to JPA entity and update persistence mapping in `backend/src/main/java/de/fete/adapter/out/persistence/EventJpaEntity.java` and `EventPersistenceAdapter.java`
+- [x] T009 [P] Update Create Event flow to accept and validate `timezone` (must be valid IANA zone ID via `ZoneId.getAvailableZoneIds()`) in `backend/src/main/java/de/fete/application/service/EventService.java` and `EventController.java`
+- [x] T010 Create `GetEventUseCase` inbound port with `getByEventToken(UUID): Optional<Event>` in `backend/src/main/java/de/fete/domain/port/in/GetEventUseCase.java`
+- [x] T011 Implement `GetEventUseCase` in `backend/src/main/java/de/fete/application/service/EventService.java` — delegates to existing `findByEventToken()` repository method
+- [x] T012 Implement `getEvent()` in `backend/src/main/java/de/fete/adapter/in/web/EventController.java` — maps domain Event to GetEventResponse, computes `expired` (expiryDate vs server clock) and `attendeeCount` (hardcoded 0)
+
+**Checkpoint**: Backend complete — `GET /api/events/{token}` returns 200 or 404. All backend tests pass.
+
+---
+
+## Phase 3: User Story 1 — View Event Details as Guest (Priority: P1) MVP
+
+**Goal**: A guest opens a shared event link and sees all event information: title, date/time with IANA timezone, description, location, attendee count. Loading shows skeleton shimmer.
+
+**Independent Test**: Navigate to a valid event URL, verify all fields display correctly with locale-formatted date/time.
+
+### Tests for User Story 1
+
+- [x] T013 [P] [US1] Unit tests for EventDetailView loaded state: renders title, date/time (locale-formatted via `Intl.DateTimeFormat`), timezone, description, location, attendee count — in `frontend/src/__tests__/EventDetailView.spec.ts`
+- [x] T014 [P] [US1] Unit test for EventDetailView loading state: renders skeleton shimmer placeholders — in `frontend/src/__tests__/EventDetailView.spec.ts`
+
+### Implementation for User Story 1
+
+- [x] T015 [P] [US1] Add skeleton shimmer CSS (CSS-only gradient animation, no dependencies) in `frontend/src/assets/main.css`
+- [x] T016 [US1] Create `EventDetailView.vue` with loading (skeleton shimmer) and loaded states — fetches event via `openapi-fetch` GET `/events/{token}`, formats date/time with `Intl.DateTimeFormat` using browser locale — in `frontend/src/views/EventDetailView.vue`
+- [x] T017 [US1] Update router to use `EventDetailView` for `/events/:token` route in `frontend/src/router/index.ts`
+- [x] T018 [P] [US1] Update `EventCreateView.vue` to send `timezone` field (auto-detected via `Intl.DateTimeFormat().resolvedOptions().timeZone`) in `frontend/src/views/EventCreateView.vue`
+- [x] T019 [US1] E2E test for loaded event: navigate to valid event URL, verify all fields displayed, verify no external resource requests — in `frontend/e2e/event-view.spec.ts`
+
+**Checkpoint**: US1 complete — guest can view event details. Skeleton shimmer during loading. Date/time locale-formatted with timezone label.
+
+---
+
+## Phase 4: User Story 2 — View Expired Event (Priority: P2)
+
+**Goal**: A guest opens a link to an expired event. The page shows event details plus a clear "event has ended" indicator. No RSVP actions shown.
+
+**Independent Test**: Create an event with past expiry date, navigate to its URL, verify "event has ended" state renders and no RSVP controls are present.
+
+**Dependencies**: Requires Phase 3 (EventDetailView exists).
+
+### Tests for User Story 2
+
+- [x] T020 [P] [US2] Unit test for EventDetailView expired state: renders "event has ended" indicator, RSVP controls absent from DOM — in `frontend/src/__tests__/EventDetailView.spec.ts`
+
+### Implementation for User Story 2
+
+- [x] T021 [US2] Add expired state rendering to `EventDetailView.vue`: show event details + "event has ended" banner when `expired === true`, no RSVP actions in DOM — in `frontend/src/views/EventDetailView.vue`
+- [x] T022 [US2] E2E test for expired event: MSW returns event with `expired: true`, verify banner and absent RSVP controls — in `frontend/e2e/event-view.spec.ts`
+
+**Checkpoint**: US2 complete — expired events clearly show "ended" state.
+
+---
+
+## Phase 5: User Story 4 — Event Not Found (Priority: P2)
+
+**Goal**: A guest navigates to an invalid event URL. The page shows a clear "event not found" message — no partial data, no error traces.
+
+**Independent Test**: Navigate to a URL with an unknown event token, verify "event not found" message renders.
+
+**Dependencies**: Requires Phase 3 (EventDetailView exists). No dependency on US2.
+
+### Tests for User Story 4
+
+- [x] T023 [P] [US4] Unit test for EventDetailView not-found state: renders "event not found" message, no event data in DOM — in `frontend/src/__tests__/EventDetailView.spec.ts`
+
+### Implementation for User Story 4
+
+- [x] T024 [US4] Add not-found state rendering to `EventDetailView.vue`: show "event not found" message when API returns 404 — in `frontend/src/views/EventDetailView.vue`
+- [x] T025 [US4] E2E test for event not found: MSW returns 404 ProblemDetail, verify message and no event data — in `frontend/e2e/event-view.spec.ts`
+
+**Checkpoint**: US4 complete — invalid tokens show friendly not-found message.
+
+---
+
+## Phase 6: Polish & Cross-Cutting Concerns
+
+**Purpose**: Server error edge case, final validation, and cleanup.
+
+- [x] T026 Add server error state with manual retry button to `EventDetailView.vue`: friendly error message + "Retry" button that re-fetches — in `frontend/src/views/EventDetailView.vue`
+- [x] T027 [P] Unit test for server error + retry state in `frontend/src/__tests__/EventDetailView.spec.ts`
+- [x] T028 [P] E2E test for server error: MSW returns 500, verify error message and retry button functionality — in `frontend/e2e/event-view.spec.ts`
+- [x] T029 Run quickstart.md validation: verify all key changes listed in quickstart.md are implemented
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies — start immediately
+- **Foundational (Phase 2)**: Depends on T001 (OpenAPI spec) and T002 (migration) from Setup
+- **US1 (Phase 3)**: Depends on Phase 2 completion (backend endpoint must exist)
+- **US2 (Phase 4)**: Depends on Phase 3 (EventDetailView exists) — can parallelize with US4
+- **US4 (Phase 5)**: Depends on Phase 3 (EventDetailView exists) — can parallelize with US2
+- **Polish (Phase 6)**: Depends on Phase 3 minimum; ideally after US2 + US4
+
+### User Story Dependencies
+
+```
+Phase 1 (Setup) ──► Phase 2 (Backend) ──► Phase 3 (US1/MVP)
+                                               │
+                                          ┌────┴────┐
+                                          ▼         ▼

+                                          Phase 6 (Polish)
+```
+
+- **US1 (P1)**: Requires Phase 2 — no dependency on other stories
+- **US2 (P2)**: Requires US1 (same component) — no dependency on US4
+- **US4 (P2)**: Requires US1 (same component) — no dependency on US2
+- **US3 (P2)**: DEFERRED until US-18 (cancel event) is implemented
+
+### Within Each Phase
+
+- Tests MUST be written and FAIL before implementation (TDD)
+- Models/ports before services
+- Services before controllers
+- Backend before frontend (for the same endpoint)
+
+### Parallel Opportunities
+
+**Phase 1**: T002 (migration) can run in parallel with T001 (OpenAPI update)
+**Phase 2**: T004, T005, T006 (tests) can run in parallel. T008, T009 can run in parallel after T007.
+**Phase 3**: T013, T014 (unit tests) and T015 (CSS) can run in parallel. T018 (create form timezone) is independent.
+**Phase 4 + 5**: US2 and US4 can be implemented in parallel (different UI states, same file but non-conflicting sections).
+
+---
+
+## Parallel Example: Phase 2 (Backend)
+
+```bash
+# Write all backend tests in parallel (TDD):
+Task T004: "Unit tests for GetEventUseCase"
+Task T005: "Controller tests for GET /events/{token}"
+Task T006: "Tests for timezone in Create Event flow"
+
+# Then implement in parallel where possible:
+Task T008: "Add timezone to JPA entity + persistence"  # parallel
+Task T009: "Update Create Event flow for timezone"      # parallel
+# T010-T012 are sequential (port → service → controller)
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup (OpenAPI + migration + types)
+2. Complete Phase 2: Backend (domain + use case + controller + tests)
+3. Complete Phase 3: US1 (EventDetailView + router + tests)
+4. **STOP and VALIDATE**: Guest can view event details via shared link
+5. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Setup + Backend → Backend ready, API testable via curl
+2. Add US1 → Guest can view events (MVP!)
+3. Add US2 → Expired events show "ended" state
+4. Add US4 → Invalid tokens show "not found"
+5. Polish → Server error handling, final validation
+
+### Deferred Work
+
+- **US3 (Cancelled event)**: Blocked on US-18. No tasks generated. Will require adding `cancelled` + `cancellationMessage` to GetEventResponse and a new UI state.
+
+---
+
+## Notes
+
+- [P] tasks = different files, no dependencies on incomplete tasks
+- [Story] label maps task to specific user story for traceability
+- `attendeeCount` returns 0 until RSVP feature (US-8+) is implemented (R-3)
+- `expired` is computed server-side using injected Clock bean (R-4)
+- Frontend route: `/events/:token` — API path: `/api/events/{token}` (R-5)
+- Skeleton shimmer is CSS-only, no additional dependencies (R-6)
+- Date/time formatted via `Intl.DateTimeFormat` with browser locale (spec clarification Q7)

+## Entities
+
+### Rsvp (NEW)
+
+| Field      | Type           | Required | Constraints                    | Notes                              |

+| rsvpToken  | RsvpToken      | yes      | UNIQUE, NOT NULL               | Server-generated UUID, returned to client |
+| eventId    | Long           | yes      | FK -> events.id, NOT NULL      | Which event this RSVP belongs to   |
+| name       | String         | yes      | 1-100 chars, NOT NULL          | Guest's display name               |
+
+**Notes**:
+- No `attending` boolean — existence of an entry implies attendance (per spec).
+- No `createdAt` — not required by the spec. Can be added later if needed (e.g. for guest list sorting in 009).
+- Duplicates from different devices or cleared localStorage are accepted (privacy trade-off).
+
+### Token Value Objects (NEW)
+
+| Record           | Field | Type | Notes                                         |
+|------------------|-------|------|-----------------------------------------------|
+| `EventToken`     | value | UUID | Immutable, non-null. Java record wrapping UUID |
+| `OrganizerToken` | value | UUID | Immutable, non-null. Java record wrapping UUID |
+| `RsvpToken`      | value | UUID | Immutable, non-null. Java record wrapping UUID |
+
+**Purpose**: Type-safe wrappers preventing mix-ups between the three token types at compile time. All generated server-side via `UUID.randomUUID()`. JPA entities continue to use raw `UUID` columns — mapping happens in the persistence adapters.
+
+### Event (MODIFIED — token fields change type)
+
+The Event domain model's `eventToken` and `organizerToken` fields change from raw `UUID` to their typed record wrappers. No database schema change — the JPA entity keeps raw `UUID` columns.
+
+| Field           | Old Type | New Type         |
+|-----------------|----------|------------------|
+| eventToken      | UUID     | EventToken       |
+| organizerToken  | UUID     | OrganizerToken   |
+
+The `attendeeCount` was already added to the API response in 007-view-event — it now gets populated from a count query instead of returning 0.
+
+### StoredEvent (frontend localStorage — modified)

+| rsvpName       | string | no       | **NEW** — guest's submitted name    |
+
+## Validation Rules
+
+- `name`: required, 1-100 characters, trimmed. Blank or whitespace-only is rejected.

+# Implementation Plan: RSVP to an Event
+
+**Branch**: `008-rsvp` | **Date**: 2026-03-06 | **Spec**: [spec.md](spec.md)
+**Input**: Feature specification from `/specs/008-rsvp/spec.md`
+
+## Summary
+
+Add RSVP functionality to the event detail page. Backend: new `POST /api/events/{eventToken}/rsvps` endpoint that persists an RSVP (guest name) and returns an `rsvpToken`. Populates the existing `attendeeCount` field with real data from a count query. Rejects RSVPs on expired events (409). Frontend: fullscreen event presentation with sticky bottom bar (RSVP CTA or status), bottom sheet with RSVP form (name + submit). localStorage stores rsvpToken and name per event. No account required.
+
+## Technical Context
+
+**Language/Version**: Java 25 (backend), TypeScript 5.9 (frontend)
+**Primary Dependencies**: Spring Boot 3.5.x, Vue 3, Vue Router 5, openapi-fetch, openapi-typescript
+**Storage**: PostgreSQL (JPA via Spring Data, Liquibase migrations)
+**Testing**: JUnit (backend), Vitest (frontend unit), Playwright + MSW (frontend E2E)
+**Target Platform**: Self-hosted web application (Docker)
+**Project Type**: Web service + SPA
+**Performance Goals**: N/A (single-user scale, self-hosted)
+**Constraints**: No external resources (CDNs, fonts, tracking), WCAG AA, privacy-first, no PII logging
+**Scale/Scope**: New RSVP domain (model + service + controller + persistence), new frontend components (bottom sheet, sticky bar), modified event detail view
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| I. Privacy by Design | PASS | No PII logged. Only guest-entered name stored. No IP logging. No tracking. Attendee names not exposed publicly (count only). Unprotected endpoint is a conscious privacy trade-off per spec. |
+| II. Test-Driven Methodology | PASS | TDD enforced: backend unit + integration tests, frontend unit tests, E2E tests. Tests written before implementation. |
+| III. API-First Development | PASS | OpenAPI spec updated first. New endpoint + schemas with `example:` fields. Types generated before implementation. |
+| IV. Simplicity & Quality | PASS | Minimal scope: one POST endpoint, one domain entity, one bottom sheet component. No CAPTCHA, no rate limiting, no edit/withdraw (deferred). Cancelled event guard deferred to US-18. |
+| V. Dependency Discipline | PASS | No new dependencies. Bottom sheet is CSS + Vue (~50 lines). No UI library. |
+| VI. Accessibility | PASS | Bottom sheet uses dialog role + aria-modal. Focus trap. ESC to close. Keyboard navigable. WCAG AA contrast via design system. |
+
+**Post-Phase-1 re-check**: All gates still pass. Three token value objects (`EventToken`, `OrganizerToken`, `RsvpToken`) introduced uniformly — justified by spec requirement for type-safe tokens. Refactoring existing Event model to use typed tokens is a mechanical change well-covered by existing tests.

+**Structure Decision**: Extends the existing web application structure (backend + frontend). Adds a new RSVP domain following the same hexagonal architecture pattern established in 006-create-event and 007-view-event. Cross-cutting refactoring introduces typed token value objects (`EventToken`, `OrganizerToken`, `RsvpToken`) across all layers. Two new frontend components (`BottomSheet`, `RsvpBar`) are the first entries in `src/components/` — justified because they're reusable UI primitives, not view-specific markup.

+# Quickstart: RSVP to an Event (008)
+
+## What this feature adds
+
+1. **Backend**: New `POST /api/events/{eventToken}/rsvps` endpoint that accepts an RSVP (guest name) and returns an `rsvpToken`. Populates the existing `attendeeCount` field in `GET /events/{token}` with real data.
+
+2. **Frontend**: Bottom sheet RSVP form on the event detail page. Sticky bottom bar with CTA (or status after RSVP). localStorage persistence of RSVP data.
+
+## Implementation order
+
+1. **Token value objects** — Create `EventToken`, `OrganizerToken`, `RsvpToken` records. Refactor `Event` domain model and all layers (service, controller, repository, persistence adapter, tests) to use typed tokens instead of raw UUID.
+2. **OpenAPI spec** — Add `CreateRsvpRequest`, `CreateRsvpResponse`, and the `POST /events/{eventToken}/rsvps` endpoint.
+3. **Liquibase migration** — Create `rsvps` table (003-create-rsvps-table.xml).
+4. **Domain model** — `Rsvp` entity using `RsvpToken`.
+5. **Ports** — `CreateRsvpUseCase` (in), `RsvpRepository` (out).
+6. **Persistence adapter** — `RsvpJpaEntity`, `RsvpJpaRepository`, `RsvpPersistenceAdapter`.
+7. **Service** — `RsvpService` implementing `CreateRsvpUseCase`.
+8. **Controller** — Add `createRsvp()` to `EventController`.
+9. **Attendee count** — Wire `RsvpRepository.countByEventId()` into the GET event flow.
+10. **Frontend composable** — Extend `useEventStorage` with `rsvpToken`/`rsvpName`.
+11. **Frontend UI** — Bottom sheet component, sticky bar, RSVP form.
+12. **E2E tests** — RSVP submission, expired event guard, localStorage verification.

+# Research: RSVP to an Event (008)
+
+**Date**: 2026-03-06 | **Status**: Complete
+
+## R-1: RSVP Endpoint Design
+
+**Decision**: `POST /api/events/{eventToken}/rsvps` creates an RSVP. Returns `201` with `rsvpToken` on success. Rejects with `409 Conflict` if event expired.
+
+**Rationale**: RSVPs are a sub-resource of events — nesting under the event token is RESTful and groups operations logically. The event token in the path identifies the event; no separate event ID in the request body needed.
+
+**Flow**:
+1. `EventController` implements generated `EventsApi.createRsvp()` — same controller, same tag, sub-resource of events.
+2. Controller resolves the event via `eventToken`, checks expiry.
+3. New inbound port: `CreateRsvpUseCase` with `createRsvp(CreateRsvpCommand): Rsvp`.
+4. `RsvpService` validates event exists + not expired, persists RSVP, returns domain model.
+5. Controller maps to `CreateRsvpResponse` DTO (contains `rsvpToken`).
+6. 404 if event not found, 409 if event expired, 400 for validation errors.
+
+**Alternatives considered**:
+- `POST /api/rsvps` with eventToken in body — rejected because RSVPs are always scoped to an event. Nested resource is cleaner.
+- Separate `RsvpController` — rejected because the URL is under `/events/`, so it belongs in `EventController`. One controller per resource root (KISS).
+- `PUT` instead of `POST` — rejected because the client doesn't know the rsvpToken before creation.
+
+## R-2: Token Value Objects
+
+**Decision**: Introduce all three token types as Java records wrapping `UUID`: `EventToken`, `OrganizerToken`, and `RsvpToken`. Refactor the existing `Event` domain model and all layers (service, controller, repository, persistence adapter) to use the typed tokens instead of raw `UUID`.
+
+**Rationale**: The spec mandates typed token records. Introducing `RsvpToken` alone while leaving the other two as raw UUIDs would create an inconsistency in the domain model. All three tokens serve the same purpose (type-safe identification) and should be modeled uniformly. The cross-cutting refactoring touches existing code but is mechanical and well-covered by existing tests.
+
+**Implementation pattern** (same for all three):
+```java
+package de.fete.domain.model;
+
+public record EventToken(UUID value) {
+    public EventToken {
+        Objects.requireNonNull(value, "eventToken must not be null");
+    }
+
+    public static EventToken generate() {
+        return new EventToken(UUID.randomUUID());
+    }
+}
+```
+
+```java
+public record OrganizerToken(UUID value) { /* same pattern */ }
+public record RsvpToken(UUID value) { /* same pattern */ }
+```
+
+**Impact on existing code**:
+- `Event.java`: `UUID eventToken` → `EventToken eventToken`, `UUID organizerToken` → `OrganizerToken organizerToken`
+- `EventService.java`: `UUID.randomUUID()` → `EventToken.generate()` / `OrganizerToken.generate()`
+- `EventController.java`: unwrap tokens at API boundary (`token.value()`)
+- `EventRepository.java` / `EventPersistenceAdapter.java`: map between domain tokens and raw UUIDs for JPA
+- `EventJpaEntity.java`: stays with raw `UUID` columns (JPA mapping layer)
+- All existing tests: update to use typed tokens
+
+**Alternatives considered**:
+- Use raw UUID everywhere — rejected because the spec explicitly requires typed records and they prevent mixing up token types at compile time.
+- Introduce only `RsvpToken` now — rejected because it creates an inconsistency. All three should be uniform.
+
+## R-3: Attendee Count Population
+
+**Decision**: Populate `attendeeCount` in `GetEventResponse` by counting RSVP rows for the event. The count query lives in the `RsvpRepository` port and is called by `EventService` (or a query in `RsvpService` delegated to by `EventController`).
+
+**Rationale**: The `attendeeCount` field already exists in the API contract (returns 0 today per R-3 in 007). Now it gets real data. Since an RSVP entry's existence implies attendance (no `attending` boolean), the count is simply `COUNT(*) WHERE event_id = ?`.
+
+**Implementation approach**: Add `countByEventId(Long eventId)` to `RsvpRepository`. `EventService.getByEventToken()` returns the Event domain object; the controller queries the RSVP count separately and sets it on the response. This keeps Event and RSVP domains loosely coupled.
+
+**Alternatives considered**:
+- Store count on the Event entity (denormalized) — rejected because it introduces update anomalies and requires synchronization logic.
+- Join query in EventRepository — rejected because it couples Event persistence to RSVP schema.
+
+## R-4: Expired Event Guard
+
+**Decision**: Both client and server enforce the expiry guard. Client hides the RSVP form when `expired === true` (from GetEventResponse). Server rejects `POST /rsvps` with `409 Conflict` when `event.expiryDate < today`.
+
+**Rationale**: Defense in depth. The client check is UX (don't show a form that can't succeed). The server check is the authoritative guard (clients can be bypassed). Using `409 Conflict` rather than `400 Bad Request` because the request format is valid — it's the event state that prevents the operation.
+
+**Alternatives considered**:
+- Client-only guard — rejected because clients can be bypassed.
+- `400 Bad Request` — rejected because the request body is valid; the conflict is with the event's state.
+- `422 Unprocessable Entity` — acceptable but `409` better communicates "the resource state conflicts with this operation."
+
+## R-5: localStorage Schema for RSVP
+
+**Decision**: Extend the existing `fete:events` localStorage structure. Each `StoredEvent` entry gains optional `rsvpToken` and `rsvpName` fields.
+
+**Rationale**: The existing `useEventStorage` composable already stores events by token. Adding RSVP data to the same entry avoids a second localStorage key and keeps event data co-located. The spec requires storing: rsvpToken, name, event token, event title, event date — the last three are already in `StoredEvent`.
+
+**Schema change**:
+```typescript
+interface StoredEvent {
+  eventToken: string
+  organizerToken?: string   // existing (for organizers)
+  title: string             // existing
+  dateTime: string          // existing
+  expiryDate: string        // existing
+  rsvpToken?: string        // NEW — present after RSVP
+  rsvpName?: string         // NEW — guest's submitted name
+}
+```
+
+**Alternatives considered**:
+- Separate `fete:rsvps` localStorage key — rejected because it duplicates event metadata (title, date) and complicates lookups.
+- IndexedDB — rejected (over-engineering for a few KBs of data).
+
+## R-6: Bottom Sheet UI Pattern
+
+**Decision**: Implement the bottom sheet as a Vue component using CSS transforms and transitions. No UI library dependency.
+
+**Rationale**: The spec requires a bottom sheet for the RSVP form. A custom implementation using `transform: translateY()` with CSS transitions is lightweight, accessible, and avoids new dependencies (Principle V). The sheet slides up from the bottom on open and back down on close.
+
+**Key implementation details**:
+- Overlay backdrop (semi-transparent) with click-to-dismiss
+- `<dialog>` element or ARIA `role="dialog"` with `aria-modal="true"`
+- Focus trap inside the sheet (keyboard accessibility)
+- ESC key to close
+- Transition: `transform 0.3s ease-out`
+- Mobile: full-width, max-height ~50vh. Desktop: full-width within the 480px column.
+
+**Alternatives considered**:
+- Modal/dialog instead of bottom sheet — rejected because bottom sheets are the mobile-native pattern for contextual actions.
+- Headless UI library (e.g., @headlessui/vue) — rejected because it adds a dependency for a single component. Custom implementation is ~50 lines.
+
+## R-7: Sticky Bottom Bar
+
+**Decision**: The sticky bar is a `position: fixed` element at the bottom of the viewport, within the content column (max 480px). It contains either the RSVP CTA button or the RSVP status text.
+
+**Rationale**: The spec defines two states for the bar:
+1. **No RSVP**: Shows CTA button (accent color, "Ich bin dabei!" or similar)
+2. **Has RSVP**: Shows status text ("Du kommst!" + edit hint, though edit is out of scope)
+
+The bar state is determined by checking localStorage for an rsvpToken for the current event.
+
+**CSS pattern**:
+```css
+.sticky-bar {
+  position: fixed;
+  bottom: 0;
+  left: 50%;
+  transform: translateX(-50%);
+  width: 100%;
+  max-width: 480px; /* matches content column */
+  padding: 1rem 1.2rem;
+  /* glass-morphism or solid surface */
+}
+```
+
+**Alternatives considered**:
+- `position: sticky` at bottom of content — rejected because it only sticks within the scroll container, not the viewport. Fixed is needed for always-visible CTA.
+
+## R-8: Cancelled Event Guard (Deferred)
+
+**Decision**: FR-010 (cancelled event guard) is deferred per spec. The code will NOT check for cancellation status. This will be added when US-18 (cancel event) is implemented.
+
+**Rationale**: No cancellation field exists on the Event model yet. Adding a guard for a non-existent state violates KISS (Principle IV).
