+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.

+## Nicht umgesetzte Feature-Ideen (ehemals Specs 009–026)
+
+### 009 – Gästeliste
+Organisator sieht alle RSVPs (Name, Status) und kann einzelne Einträge löschen.
+* Nur mit gültigem Organizer-Token sichtbar
+* Gäste ohne Token sehen keine Gästeliste
+* Löschung serverseitig validiert
+
+### 010 – Event bearbeiten
+Organisator kann Titel, Beschreibung, Datum, Ort und Ablaufdatum ändern.
+* Formular vorausgefüllt mit aktuellen Werten
+* Ablaufdatum muss in der Zukunft liegen
+* Ohne Organizer-Token kein Edit-UI sichtbar
+
+### 011 – Event merken/bookmarken
+Gäste können Events lokal merken, ohne RSVP abzugeben — rein clientseitig via localStorage.
+* Kein Serverkontakt nötig
+* Unabhängig vom RSVP-Status
+* Auch bei abgelaufenen Events möglich
+
+### 012 – Lokale Event-Übersicht
+Startseite (`/`) zeigt alle getrackten Events (erstellt, zugesagt, gemerkt) aus localStorage.
+* Zeigt Titel, Datum, Beziehungstyp (Organisator/Gast/Gemerkt)
+* Vergangene Events als "beendet" markiert
+* Einträge können entfernt werden
+
+### 013 – Kalender-Export
+.ics-Download (RFC 5545) mit Event-Details, optional webcal:// für Live-Updates.
+* Stabile UID aus Event-Token (Re-Import aktualisiert statt dupliziert)
+* Bei Absage: STATUS:CANCELLED im .ics
+* Kein externer Kalenderservice kontaktiert
+
+### 014 – Änderungen hervorheben
+Geänderte Felder werden visuell hervorgehoben, wenn der Gast seit der letzten Änderung nicht mehr auf der Seite war.
+* Server trackt `last_edited_at` + geänderte Feldnamen
+* Client speichert `last_seen_at` in localStorage
+* Privacy-freundlich: kein serverseitiges Read-Tracking
+
+### 015 – Organisator-Updates
+Organisator kann Textnachrichten im Event posten (Pinnwand-Stil).
+* Chronologisch sortiert, löschbar durch Organisator
+* Nach Ablauf kein Posting mehr möglich
+* Ohne Organizer-Token kein Compose-UI
+
+### 016 – Gast-Benachrichtigungen
+Badge/Indikator bei ungelesenen Organisator-Updates, rein clientseitig via localStorage.
+* Eigener Timestamp `updates_last_seen_at` (getrennt von Feld-Änderungen)
+* Kein Indikator beim ersten Besuch
+* Kein serverseitiges Tracking (Privacy)
+
+### 017 – QR-Code
+Event-Seite zeigt QR-Code mit der öffentlichen Event-URL.
+* Serverseitig generiert (kein externer QR-Service)
+* Download als SVG oder hochauflösendes PNG
+* Auch bei abgelaufenen Events verfügbar
+
+### 018 – Datenlöschung
+Automatische Löschung aller Event-Daten nach Ablaufdatum (Privacy-Garantie).
+* Scheduled Job oder Lazy Cleanup bei Zugriff
+* Löscht Event, RSVPs, Updates, Bilder, Metadaten
+* Idempotent, kein PII im Log
+
+### 019 – Instanz-Limit
+`MAX_ACTIVE_EVENTS` als Env-Variable begrenzt aktive Events für Self-Hoster.
+* 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 löscht Event permanent und unwiderruflich.
+* Entfernt alle zugehörigen Daten sofort
+* localStorage-Eintrag wird entfernt, Redirect zu `/`
+* 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)
+* WCAG AA konform
+* Verhindert leere Seiten bei Fehlnavigation

+# Modern UI Effects Research (2025-2026)
+
+## Liquid Glass (Apple WWDC 2025)
+Evolved glassmorphism with directional lighting. Three-layer approach: highlight, shadow, illumination.
+- `backdrop-filter: blur(20px) saturate(1.5)` — higher saturation than basic glass
+- `inset 0 1px 0 rgba(255,255,255,0.15)` — top highlight (light direction)
+- `inset 0 -1px 0 rgba(0,0,0,0.1)` — bottom shadow
+- Outer drop shadow for depth: `0 8px 32px rgba(0,0,0,0.3)`
+- Advanced: SVG `feTurbulence` + `feSpecularLighting` for refraction (Chromium only)
+- Browser support: `backdrop-filter` ~88%, Firefox since v103
+
+## Aurora / Gradient Mesh Backgrounds
+Stacked animated radial gradients simulating northern lights. Pairs well with glass cards on dark backgrounds.
+- Multiple `radial-gradient(ellipse ...)` layers with partial opacity
+- Animated via `background-position` shift (GPU-friendly)
+- `@property` rule enables direct gradient color animation (broad support since 2024)
+- Best for ambient background movement, not for content areas
+
+## Animated Glow Borders
+Rotating `conic-gradient` borders with blur halo. Striking on dark backgrounds.
+- Outer wrapper with `conic-gradient(from var(--angle), color1, color2, color3, color1)`
+- `::before` pseudo with `filter: blur(12px)` and `opacity: 0.5` for glow halo
+- `@property --angle` trick to animate custom property inside `conic-gradient`
+- Use sparingly — best for single highlight elements (FAB, CTA), not all cards
+
+## Modern Neumorphism (2025-2026 revision)
+Subtler than the original trend. Higher contrast, less extreme extrusion, combined with accent colors.
+- Light and dark shadow pair: `6px 6px 12px rgba(0,0,0,0.5)` + `-6px -6px 12px rgba(60,50,80,0.15)`
+- `border: 1px solid rgba(255,255,255,0.05)` for definition
+- Works on dark backgrounds with slightly lighter "uplift" shadow direction
+- Better suited for interactive elements (buttons, toggles) than content cards
+

+| 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)
+
+| Field          | Type   | Required | Notes                              |

+| eventToken     | string | yes      | Existing                           |
+| organizerToken | string | no       | Existing (organizer flow)          |
+| title          | string | yes      | Existing                           |
+| dateTime       | string | yes      | Existing                           |
+| expiryDate     | string | yes      | Existing                           |
+| rsvpToken      | string | no       | **NEW** — set after RSVP submission |
+| rsvpName       | string | no       | **NEW** — guest's submitted name    |
+
+## Validation Rules
+
+- `name`: required, 1-100 characters, trimmed. Blank or whitespace-only is rejected.
+- `rsvpToken`: server-generated, never from client input on create.
+- `eventId`: must reference an existing, non-expired event.
+
+## Relationships

+# 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).

+## Clarifications
+
+### Session 2026-03-06
+
+- Q: How should the server deduplicate RSVPs from the same device without accounts? → A: Server generates an `rsvpToken` (UUID) on first RSVP, returns it to the client. Client stores it in localStorage per event. On re-RSVP, client sends the `rsvpToken` to update instead of create. No global device identifier — the token is event-scoped. If localStorage is lost (cleared or different device), a duplicate entry is accepted as a privacy trade-off.
+- Q: Should typed token value objects be used in the backend? → A: Yes. Backend: The three token types (EventToken, OrganizerToken, RsvpToken) MUST be modeled as distinct Java record types wrapping UUID, not passed as raw UUID values. Frontend: No branded types — plain string variables with clear naming (eventToken, rsvpToken) are sufficient given TypeScript's structural typing and OpenAPI codegen.
+- Q: How should the RSVP interaction be presented on the event page? → A: Fullscreen event presentation (gradient background, later Unsplash). Title prominent at top, key facts below (description, date, attendee count) — spacious layout. Sticky bottom bar with RSVP CTA. Tap opens a bottom sheet with the RSVP form. After RSVP, the bar shows status ("Du kommst!" + edit option) instead of the CTA.
+- Q: How does the RSVP form handle declining? → A: There is no explicit "not attending" button. The bottom sheet only offers the attending flow (name + submit). To not attend, the guest simply closes the sheet. Withdrawing an existing RSVP (DELETE with rsvpToken) is out of scope — deferred to a separate edit-RSVP spec.
+- Q: Should the attendee name list be publicly visible on the event page? → A: No. Only the attendee count is shown publicly. The full name list is visible only to the organizer (via organizer link). This maximizes guest privacy.
+- Q: Should the RSVP endpoint have spam/abuse protection? → A: No. The RSVP endpoint is intentionally unprotected — risk is consciously accepted as a privacy trade-off consistent with the no-account, no-tracking philosophy. Protection measures can be retrofitted in a separate spec if real-world abuse occurs. KISS.
+- Q: How is the attendee count delivered and updated? → A: As a new `attendeeCount` field in the existing Event response (no separate endpoint). Loaded once on page load, no polling or WebSocket. After the guest's own RSVP submission, the count is optimistically incremented (+1) client-side. KISS.
+- Q: What determines the RSVP cutoff? → A: The event date itself. No separate expiry field. After the event date has passed, RSVPs are blocked (form hidden, server rejects).
+- Q: Should the RSVP entity have an `attending` boolean field? → A: No. The server only stores attending RSVPs — existence of an entry implies attendance. No `attending` boolean needed. Deletion of entries (withdrawal) is deferred to the edit-RSVP spec.

 ## User Scenarios & Testing
 
 ### User Story 1 - Submit an RSVP (Priority: P1)
 
-A guest opens an active event page and indicates whether they will attend. If attending, they must provide their name. If not attending, the name is optional. The RSVP is sent to the server and persisted. The guest's choice, name, event token, title, and date are saved in localStorage.
+A guest opens an active event page, which presents the event fullscreen (gradient background, title prominent at top, key facts below including attendee count). A sticky bottom bar shows an RSVP call-to-action. Tapping opens a bottom sheet with the RSVP form: name field + submit. The RSVP is sent to the server and persisted. The server returns an rsvpToken which, along with the name, event token, title, and date, is saved in localStorage. After submission, the bottom sheet closes and the sticky bar shows the guest's RSVP status. To not attend, the guest simply closes the sheet — no server request.
 
 **Why this priority**: Core interactive feature of the app. Without it, guests cannot communicate attendance, and the attendee list (US-2) has no data.

-### User Story 2 - Re-RSVP from the Same Device (Priority: P2)
-
-A returning guest on the same device opens an event page where they previously submitted an RSVP. The form pre-fills with their prior choice and name. Re-submitting updates the existing RSVP rather than creating a duplicate.
-
-**Why this priority**: Prevents duplicate entries and provides a better UX for guests who want to change their mind. Depends on Story 1 populating localStorage.
-
-**Independent Test**: Can be tested by RSVPing once, then reloading the event page and verifying the form is pre-filled and a second submission updates rather than duplicates the server-side record.

 ## Requirements
 
 ### Functional Requirements
 
-- **FR-001**: The RSVP form MUST offer exactly two choices: "I'm attending" and "I'm not attending".
-- **FR-002**: When the guest selects "I'm attending", the name field MUST be required; submission MUST be blocked if the name is blank.
-- **FR-003**: When the guest selects "I'm not attending", the name field MUST be optional; submission MUST succeed without a name.
-- **FR-004**: On successful RSVP submission, the server MUST persist the RSVP associated with the event.
-- **FR-005**: On successful RSVP submission, the client MUST store the guest's RSVP choice and name in localStorage, keyed by event token.
+- **FR-001**: The RSVP bottom sheet MUST offer an attending flow only: name field (required, max 100 characters) + submit. There is no explicit "not attending" option — the guest simply closes the sheet.
+- **FR-002**: Submission MUST be blocked if the name is blank or exceeds 100 characters.
+- **FR-003**: If a prior RSVP for this event exists in localStorage (rsvpToken present), the sticky bottom bar MUST show the guest's RSVP status instead of the initial CTA. Editing the RSVP (name change, withdrawal) is out of scope for this spec.
+- **FR-004**: On successful attending RSVP submission, the server MUST persist the RSVP associated with the event and return an rsvpToken.
+- **FR-005**: On successful RSVP submission, the client MUST store the guest's name and the server-returned rsvpToken in localStorage, keyed by event token.
 - **FR-006**: On successful RSVP submission, the client MUST store the event token, event title, and event date in localStorage (to support the local event overview, US-7).
-- **FR-007**: If a prior RSVP for this event exists in localStorage, the form MUST pre-fill with the stored choice and name on page load.
-- **FR-008**: Re-submitting an RSVP from a device that has an existing server-side entry for this event MUST update the existing entry, not create a new one.
+- **FR-013**: The event page MUST present the event fullscreen with a sticky bottom bar containing the RSVP call-to-action. Tapping the CTA MUST open a bottom sheet with the RSVP form.
+- **FR-014**: After successful RSVP submission, the bottom sheet MUST close and the sticky bar MUST transition to showing the RSVP status.
 - **FR-009**: The RSVP form MUST NOT be shown and the server MUST reject RSVP submissions after the event's expiry date has passed.
 - **FR-010**: The RSVP form MUST NOT be shown and the server MUST reject RSVP submissions if the event has been cancelled [enforcement deferred until US-18 is implemented].
-- **FR-011**: RSVP submission MUST NOT require an account, login, or any personal data beyond the optionally entered name.
+- **FR-011**: RSVP submission MUST NOT require an account, login, or any personal data beyond the entered name.
 - **FR-012**: No personal data or IP address MUST be logged on the server when processing an RSVP.
+- **FR-015**: The event page MUST show only the attendee count publicly. The full attendee name list is out of scope (see 009-guest-list).
 
 ### Key Entities
 
-- **RSVP**: Represents a guest's attendance declaration. Attributes: event token reference, attending status (boolean), optional name, creation/update timestamp. The server-side identity key for deduplication is the combination of event token and a device-bound identifier [NEEDS EXPANSION: deduplication mechanism to be defined during implementation].
+- **RSVP**: Represents a guest's attendance declaration. Attributes: rsvpToken (server-generated UUID, returned to client), event reference, name (required), creation timestamp. Existence of an entry implies attendance — no `attending` boolean. The rsvpToken is returned to the client for future use (editing/withdrawal in a later spec). Duplicates from lost localStorage or different devices are accepted as a privacy trade-off.
+- **RsvpToken**: A server-generated, event-scoped UUID identifying a single RSVP entry. Modeled as a distinct Java record type (alongside EventToken and OrganizerToken). Stored client-side in localStorage per event.
 
 ## Success Criteria
 
 ### Measurable Outcomes
 
-- **SC-001**: A guest can submit an RSVP (attending with name, or not attending without name) from the event page without an account.
-- **SC-002**: Submitting an RSVP from the same device twice results in exactly one server-side RSVP entry for that guest (no duplicates).
+- **SC-001**: A guest can submit an RSVP (name + submit) from the event page without an account.
+- **SC-002**: After submitting, the sticky bar shows the guest's RSVP status (not the CTA).
 - **SC-003**: After submitting an RSVP, the local event overview (US-7) can display the event without a server request (event token, title, and date are in localStorage).
 - **SC-004**: The RSVP form is not shown on expired events, and direct server submissions for expired events are rejected.
 - **SC-005**: No name, IP address, or personal data beyond the submitted name is stored or logged by the server in connection with an RSVP.

+# Tasks: RSVP to an Event
+
+**Input**: Design documents from `/specs/008-rsvp/`
+**Prerequisites**: plan.md, spec.md, data-model.md, contracts/create-rsvp.yaml, research.md, quickstart.md
+
+**Tests**: Included — constitution mandates Test-Driven Methodology (tests before implementation).
+
+**Organization**: Tasks grouped by user story for independent implementation and testing.
+
+## 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)
+- Exact file paths included in descriptions
+
+## Phase 1: Setup
+
+**Purpose**: OpenAPI spec and database migration — shared infrastructure for all user stories
+
+- [x] T001 Update OpenAPI spec with RSVP endpoint, request/response schemas, and `attendeeCount` population in `backend/src/main/resources/openapi/api.yaml`
+- [x] T002 [P] Create Liquibase migration for rsvps table in `backend/src/main/resources/db/changelog/003-create-rsvps-table.xml`
+- [x] T003 [P] Include new migration in `backend/src/main/resources/db/changelog/db.changelog-master.xml`
+
+---
+
+## Phase 2: Foundational (Blocking Prerequisites)
+
+**Purpose**: Token value objects and cross-cutting refactoring — MUST complete before user stories
+
+**Why blocking**: All new RSVP code uses typed tokens. Existing code must be refactored first to avoid mixing raw UUID and typed tokens.
+
+- [x] T004 [P] Create `EventToken` record in `backend/src/main/java/de/fete/domain/model/EventToken.java`
+- [x] T005 [P] Create `OrganizerToken` record in `backend/src/main/java/de/fete/domain/model/OrganizerToken.java`
+- [x] T006 [P] Create `RsvpToken` record in `backend/src/main/java/de/fete/domain/model/RsvpToken.java`
+- [x] T007 Refactor `Event` domain model to use `EventToken`/`OrganizerToken` in `backend/src/main/java/de/fete/domain/model/Event.java`
+- [x] T008 Refactor `EventRepository` port to use typed tokens in `backend/src/main/java/de/fete/domain/port/out/EventRepository.java`
+- [x] T009 Refactor `EventPersistenceAdapter` to map typed tokens in `backend/src/main/java/de/fete/adapter/out/persistence/EventPersistenceAdapter.java`
+- [x] T010 Refactor `EventService` to use typed tokens in `backend/src/main/java/de/fete/application/service/EventService.java`
+- [x] T011 Refactor `EventController` to unwrap/wrap typed tokens at API boundary in `backend/src/main/java/de/fete/adapter/in/web/EventController.java`
+- [x] T012 Update `EventServiceTest` to use typed tokens in `backend/src/test/java/de/fete/application/service/EventServiceTest.java`
+- [x] T013 Update `EventControllerIntegrationTest` to use typed tokens in `backend/src/test/java/de/fete/adapter/in/web/EventControllerIntegrationTest.java`
+- [x] T014 Verify all existing tests pass after token refactoring (`cd backend && ./mvnw test`)
+
+**Checkpoint**: All existing tests green with typed tokens. New RSVP domain work can begin.
+
+---
+
+## Phase 3: User Story 1 — Submit an RSVP (Priority: P1) MVP
+
+**Goal**: A guest can open an active event page, tap the RSVP CTA, enter their name, submit, and see confirmation. Server persists the RSVP and returns an rsvpToken. localStorage stores RSVP data. Attendee count is populated from real data.
+
+**Independent Test**: Open an event page, submit an RSVP with a name, verify attendee count updates, verify localStorage contains rsvpToken and name.
+
+### Backend Tests for US1
+
+- [x] T015 [P] [US1] Write unit tests for `RsvpService` (create RSVP, validation, event-not-found) in `backend/src/test/java/de/fete/application/service/RsvpServiceTest.java`
+- [x] T016 [P] [US1] Write integration tests for `POST /events/{eventToken}/rsvps` (201 success, 400 validation, 404 not found) in `backend/src/test/java/de/fete/adapter/in/web/EventControllerIntegrationTest.java`
+
+### Backend Implementation for US1
+
+- [x] T017 [P] [US1] Create `Rsvp` domain entity in `backend/src/main/java/de/fete/domain/model/Rsvp.java`
+- [x] T018 [P] [US1] Create `CreateRsvpUseCase` inbound port in `backend/src/main/java/de/fete/domain/port/in/CreateRsvpUseCase.java`
+- [x] T019 [P] [US1] Create `RsvpRepository` outbound port with `save()` and `countByEventId()` in `backend/src/main/java/de/fete/domain/port/out/RsvpRepository.java`
+- [x] T020 [P] [US1] Create `RsvpJpaEntity` in `backend/src/main/java/de/fete/adapter/out/persistence/RsvpJpaEntity.java`
+- [x] T021 [P] [US1] Create `RsvpJpaRepository` (Spring Data) in `backend/src/main/java/de/fete/adapter/out/persistence/RsvpJpaRepository.java`
+- [x] T022 [US1] Implement `RsvpPersistenceAdapter` in `backend/src/main/java/de/fete/adapter/out/persistence/RsvpPersistenceAdapter.java`
+- [x] T023 [US1] Implement `RsvpService` (create RSVP logic, validate event exists) in `backend/src/main/java/de/fete/application/service/RsvpService.java`
+- [x] T024 [US1] Add `createRsvp()` method to `EventController` in `backend/src/main/java/de/fete/adapter/in/web/EventController.java`
+- [x] T025 [US1] Wire attendee count: add `countByEventId()` call to GET event flow, populate `attendeeCount` in response in `backend/src/main/java/de/fete/adapter/in/web/EventController.java`
+- [x] T026 [US1] Verify backend tests pass (`cd backend && ./mvnw test`)

+- [ ] T036 [US1] Update `EventDetailView` unit tests for RSVP integration in `frontend/src/views/__tests__/EventDetailView.spec.ts`
+
+### E2E Tests for US1
+
+- [ ] T037 [US1] Write E2E tests: RSVP submission flow, localStorage verification, attendee count update in `frontend/e2e/event-rsvp.spec.ts`
+
+**Checkpoint**: US1 complete — guest can submit RSVP, see confirmation, attendee count populated. All backend + frontend tests green.
+
+---
+
+## Phase 4: User Story 2 — RSVP Blocked on Expired Events (Priority: P2)
+
+**Goal**: Expired events hide the RSVP form and the server rejects RSVP submissions with 409 Conflict.
+
+**Independent Test**: Attempt to RSVP to an expired event — verify form is hidden client-side and server returns 409.
+
+### Tests for US2
+
+- [ ] T038 [P] [US2] Write backend test for expired event rejection (409) in `backend/src/test/java/de/fete/application/service/RsvpServiceTest.java`
+- [ ] T039 [P] [US2] Write integration test for `POST /events/{eventToken}/rsvps` returning 409 on expired event in `backend/src/test/java/de/fete/adapter/in/web/EventControllerIntegrationTest.java`

+### Implementation for US2
+
+- [ ] T040 [US2] Add expiry check to `RsvpService.createRsvp()` — throw `EventExpiredException` when event date has passed in `backend/src/main/java/de/fete/application/service/RsvpService.java`
+- [ ] T041 [US2] Handle `EventExpiredException` in `GlobalExceptionHandler` — return 409 Conflict in `backend/src/main/java/de/fete/adapter/in/web/GlobalExceptionHandler.java`
+- [ ] T042 [US2] Hide RSVP bar/form on expired events in `EventDetailView` (check `expired` field from API response) in `frontend/src/views/EventDetailView.vue`
+- [ ] T043 [US2] Write E2E test for expired event: verify RSVP form hidden, direct API call returns 409 in `frontend/e2e/event-rsvp.spec.ts`
+- [ ] T044 [US2] Verify all tests pass (`cd backend && ./mvnw test && cd ../frontend && npm run test:unit`)
+
+**Checkpoint**: US2 complete — expired events block RSVPs client-side and server-side.
+
+---
+
+## Phase 5: Polish & Cross-Cutting Concerns
+
+**Purpose**: Final verification across all stories
+
+- [ ] T045 Run full backend verify (`cd backend && ./mvnw verify`)
+- [ ] T046 Run frontend build and type-check (`cd frontend && npm run build`)
+- [ ] T047 Run all E2E tests (`cd frontend && npx playwright test`)
+- [ ] T048 Visual verification of RSVP flow using `browser-interactive-testing` skill
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies — can start immediately
+- **Foundational (Phase 2)**: Depends on T001 (OpenAPI spec) for schema awareness; T002-T003 (migration) independent
+- **US1 (Phase 3)**: Depends on Phase 2 completion (typed tokens in place)
+- **US2 (Phase 4)**: Depends on Phase 3 (RSVP creation must exist before expiry guard)
+- **Polish (Phase 5)**: Depends on all user stories complete
+
+### User Story Dependencies
+
+- **US1 (P1)**: Can start after Phase 2 — no dependency on US2
+- **US2 (P2)**: Depends on US1 (the RSVP endpoint and form must exist before adding the expiry guard)
+
+### Within Each User Story
+
+- Tests MUST be written first and FAIL before implementation
+- Domain model/ports before persistence adapters
+- Persistence before services
+- Services before controllers
+- Backend before frontend (API must exist for frontend to consume)
+- Frontend components before view integration
+- Unit tests before E2E tests
+
+### Parallel Opportunities
+
+**Phase 1**: T002 and T003 can run in parallel with T001
+**Phase 2**: T004, T005, T006 in parallel; then T007-T013 sequentially (refactoring chain)
+**Phase 3 Backend**: T015+T016 (tests) in parallel; T017+T018+T019+T020+T021 (domain/ports/JPA) in parallel; then T022→T023→T024→T025 sequential
+**Phase 3 Frontend**: T027+T028+T029 (tests) in parallel; T031+T032+T033 in parallel; then T034→T035→T036→T037 sequential
+**Phase 4**: T038+T039 (tests) in parallel; then T040→T041→T042→T043→T044 sequential
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup (OpenAPI + migration)
+2. Complete Phase 2: Foundational (token value objects + refactoring)
+3. Complete Phase 3: User Story 1 (full RSVP flow)
+4. **STOP and VALIDATE**: Guest can submit RSVP, see confirmation, attendee count works
+5. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Setup + Foundational → Token refactoring complete, schema ready
+2. Add US1 → Full RSVP flow works → Deploy/Demo (MVP!)
+3. Add US2 → Expired events guarded → Deploy/Demo
+4. Polish → All tests green, visual verification done
+
+---
+
+## Notes
+
+- Cancelled event guard (FR-010) is deferred until US-18 — NOT included in tasks
+- No CAPTCHA/rate-limiting per spec (KISS, privacy-first)
+- RSVP editing/withdrawal deferred to separate edit-RSVP spec
+- Frontend uses plain `string` for tokens (no branded types) per clarification
+- Backend uses typed records (`EventToken`, `OrganizerToken`, `RsvpToken`) per clarification

-# Feature Specification: Manage Guest List as Organizer
-
-**Feature**: `009-guest-list`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md
-
-## User Scenarios & Testing
-
-### User Story 1 - View and manage RSVPs (Priority: P1)
-
-As an event organizer, I want to view all RSVPs for my event and remove individual entries if needed, so that I have an accurate overview of attendance and can moderate erroneous or spam entries.
-
-The organizer view is accessible from the event page when a valid organizer token for that event is present in localStorage. When no organizer token is present, no organizer-specific UI is shown. The organizer can see each RSVP entry with name and attending status, and can permanently delete any entry.
-
-**Why this priority**: Core organizer capability — without it, the organizer has no way to manage erroneous or spam RSVP entries. The public attendee list is only trustworthy if the organizer can moderate it.
-
-**Independent Test**: Can be tested by creating an event (obtaining an organizer token), submitting several RSVPs via the RSVP form, then opening the organizer view to verify the list is displayed and deletion works.
-
-**Acceptance Scenarios**:
-
-1. **Given** an organizer token for an event is present in localStorage, **When** the organizer opens the event page, **Then** an organizer view link or section is visible that is not shown to guests without the token.
-2. **Given** the organizer view is open, **When** the page loads, **Then** all RSVPs for the event are listed, each showing the entry's name and attending status.
-3. **Given** the organizer view is open with at least one RSVP entry, **When** the organizer deletes an entry, **Then** the entry is permanently removed from the server and immediately disappears from the attendee list on the public event page.
-4. **Given** a visitor without an organizer token in localStorage opens the event page, **When** the page renders, **Then** no organizer-specific UI (link, button, or organizer view) is visible.
-5. **Given** the organizer view is open, **When** the organizer attempts to access it via a guessable URL without the organizer token in localStorage, **Then** organizer access is denied — it requires the organizer token established during event creation.
-6. **Given** the organizer has a valid organizer token in localStorage, **When** the organizer accesses the organizer view, **Then** no additional authentication step beyond the localStorage token is required.
-
----
-
-### Edge Cases
-
-- What happens when the organizer token is present in localStorage but the event no longer exists on the server?
-- How does the system handle a deletion request when the organizer token is invalid or has been cleared from localStorage mid-session?
-- What if all RSVPs are deleted — does the organizer view show an empty state?
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: System MUST display the organizer view (guest list management) only when a valid organizer token for that event is present in localStorage.
-- **FR-002**: System MUST hide all organizer-specific UI (links, buttons, organizer view) from visitors who do not have the organizer token in localStorage.
-- **FR-003**: Organizer view MUST list all RSVPs for the event, showing each entry's name and attending status.
-- **FR-004**: Organizer MUST be able to permanently delete any individual RSVP entry from the organizer view.
-- **FR-005**: System MUST reflect RSVP deletions immediately on the public event page — the attendee list must update without delay.
-- **FR-006**: Organizer view MUST NOT be accessible via a guessable URL — access requires the organizer token stored in localStorage during event creation (US-1).
-- **FR-007**: System MUST NOT require any additional authentication step beyond the presence of the organizer token in localStorage.
-- **FR-008**: Server MUST reject RSVP deletion requests that do not include a valid organizer token.
-
-### Key Entities
-
-- **RSVP**: An entry submitted by a guest (US-3). Attributes: event association, guest name, attending status. The organizer can delete individual entries.
-- **Organizer token**: A secret UUID stored in localStorage on the device where the event was created (US-1). Grants organizer access to the guest list management view.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: An organizer can view the complete guest list for their event from the event page without navigating away to a separate URL.
-- **SC-002**: An organizer can delete any RSVP entry and the deletion is reflected on the public event page within the same page interaction (no reload required).
-- **SC-003**: A visitor without the organizer token in localStorage sees no organizer UI at all — zero organizer-specific elements rendered.
-- **SC-004**: The organizer view is not reachable by guessing or constructing a URL — it requires the in-memory/localStorage token to render.
-- **SC-005**: No additional login, account, or authentication beyond the organizer token is required to manage the guest list.

+# Data Model: Event List on Home Page
+
+**Feature**: 009-list-events | **Date**: 2026-03-08
+
+## Entities
+
+### StoredEvent (existing — no changes)
+
+The `StoredEvent` interface in `frontend/src/composables/useEventStorage.ts` already contains all fields needed for the event list feature.
+
+```typescript
+interface StoredEvent {
+  eventToken: string        // Required — UUID, used for navigation
+  organizerToken?: string   // Present if user created this event
+  title: string             // Required — displayed on card
+  dateTime: string          // Required — ISO 8601, used for sorting + relative time
+  expiryDate: string        // Stored but not displayed in list view
+  rsvpToken?: string        // Present if user RSVP'd to this event
+  rsvpName?: string         // User's name at RSVP time
+}
+```
+
+### Validation Rules
+
+An event entry is considered **valid** for display if all of:
+- `eventToken` is a non-empty string
+- `title` is a non-empty string
+- `dateTime` is a non-empty string that parses to a valid `Date`
+
+Invalid entries are silently excluded from the list (FR-010).
+
+### Derived Properties (computed at render time)
+
+| Property | Derivation |
+|----------|-----------|
+| `isPast` | `new Date(dateTime) < new Date()` |
+| `isOrganizer` | `organizerToken !== undefined` |
+| `isAttendee` | `rsvpToken !== undefined && organizerToken === undefined` |
+| `relativeTime` | `Intl.RelativeTimeFormat` applied to `dateTime` vs now |
+| `detailRoute` | `/events/${eventToken}` |
+
+### Sorting Order
+
+1. **Upcoming events** (`dateTime >= now`): ascending by `dateTime` (soonest first)
+2. **Past events** (`dateTime < now`): descending by `dateTime` (most recently passed first)
+
+### Composable Extension
+
+The `useEventStorage` composable needs one new function:
+
+```typescript
+function removeEvent(eventToken: string): void {
+  const events = readEvents().filter((e) => e.eventToken !== eventToken)
+  writeEvents(events)
+}
+```
+
+Returned alongside existing functions from `useEventStorage()`.
+
+## State Transitions
+
+```
+localStorage read
+       │
+       ▼
+  Parse JSON ──(error)──► empty array
+       │
+       ▼
+  Validate entries ──(invalid)──► silently excluded
+       │
+       ▼
+  Split: upcoming / past
+       │
+       ▼
+  Sort each group
+       │
+       ▼
+  Concatenate ──► rendered list
+```
+
+### Remove Event Flow
+
+```
+User taps delete icon / swipes left
+       │
+       ▼
+  ConfirmDialog opens
+       │
+  ┌────┴────┐
+  │ Cancel  │  Confirm
+  │         │     │
+  │         ▼     ▼
+  │    removeEvent(token)
+  │         │
+  │         ▼
+  │    Event removed from localStorage
+  │    List re-renders (event disappears)
+  └────────────────────────────────┘

+# Implementation Plan: Event List on Home Page
+
+**Branch**: `009-list-events` | **Date**: 2026-03-08 | **Spec**: `specs/009-list-events/spec.md`
+**Input**: Feature specification from `/specs/009-list-events/spec.md`
+
+## Summary
+
+Transform the home page from a static empty-state placeholder into a dynamic event list that shows all events stored in the browser's localStorage. Each event card displays title, relative time, and role indicator (organizer/attendee). Events are sorted chronologically (upcoming first), past events appear faded, and users can remove events via delete icon or swipe gesture. A FAB provides persistent access to event creation.
+
+This is a **frontend-only** feature — no backend or API changes required. The existing `useEventStorage` composable already provides all necessary data access.
+
+## Technical Context
+
+**Language/Version**: TypeScript 5.9, Vue 3.5
+**Primary Dependencies**: Vue 3, Vue Router 5, Vite
+**Storage**: Browser localStorage via `useEventStorage` composable
+**Testing**: Vitest (unit), Playwright + MSW (E2E)
+**Target Platform**: Mobile-first PWA (centered 480px column on desktop)
+**Project Type**: Web application (frontend-only changes)
+**Performance Goals**: Event list renders within 1 second (SC-001) — trivial given localStorage read
+**Constraints**: No external dependencies, no tracking, WCAG AA, keyboard navigable
+**Scale/Scope**: Typically <50 events in localStorage; no pagination needed
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*

+# Research: Event List on Home Page
+
+**Feature**: 009-list-events | **Date**: 2026-03-08
+
+## Research Questions
+
+### 1. Relative Time Formatting with `Intl.RelativeTimeFormat`
+
+**Decision**: Use the built-in `Intl.RelativeTimeFormat` API directly — no library needed.
+
+**Rationale**: The API is supported in all modern browsers (97%+ coverage). It handles locale-aware output natively (e.g., "in 3 days", "vor 2 Tagen" for German). The spec requires exactly this (FR-002).
+
+**Implementation approach**: Create a `useRelativeTime` composable that:
+1. Takes a date string (ISO 8601) and computes the difference from `now`
+2. Selects the appropriate unit (seconds → minutes → hours → days → weeks → months → years)
+3. Returns a formatted string via `Intl.RelativeTimeFormat(navigator.language, { numeric: 'auto' })`
+4. Exposes a reactive `label` that updates (optional — can be static since the list re-reads on mount)
+
+**Alternatives considered**:
+- `date-fns/formatDistance`: Would add a dependency for something the platform already does. Rejected per Principle V.
+- `dayjs/relativeTime`: Same reasoning — unnecessary dependency.
+
+### 2. Swipe-to-Delete Gesture (FR-006b)
+
+**Decision**: Implement with native Touch API (`touchstart`, `touchmove`, `touchend`) — no gesture library.
+
+**Rationale**: The gesture is simple (horizontal swipe on a single element). A library like Hammer.js or @vueuse/gesture would be overkill for one swipe direction on one component type. Per Principle V, dependencies must provide substantial value.
+
+**Implementation approach**:
+1. Track `touchstart` X position on the event card
+2. On `touchmove`, calculate delta-X; if leftward and exceeds threshold (~80px), reveal delete action
+3. On `touchend`, either snap back or trigger confirmation
+4. CSS `transform: translateX()` with `transition` for smooth animation
+5. Desktop users use the visible delete icon (no swipe needed)
+
+**Alternatives considered**:
+- `@vueuse/gesture`: Wraps Hammer.js, adds ~15KB. Rejected — too heavy for one gesture.
+- CSS `scroll-snap` trick: Clever but brittle and poor accessibility. Rejected.
+
+### 3. Past Event Visual Fading (FR-009)
+
+**Decision**: Use CSS `opacity` reduction + `filter: saturate()` for faded appearance.
+
+**Rationale**: The spec says "subtle reduction in contrast and saturation" — not a blunt grey-out. Combining `opacity: 0.6` with `filter: saturate(0.5)` achieves this while keeping text readable. Must verify WCAG AA contrast on the faded state.
+
+**Implementation approach**:
+- Add a `.event-card--past` modifier class
+- Apply `opacity: 0.55; filter: saturate(0.4)` (tune exact values for WCAG AA)
+- Keep `pointer-events: auto` and normal hover/focus styles so the card remains interactive
+- The card still navigates to the event detail page on click
+
+**Contrast verification**: The card text (`#1C1C1E` on `#FFFFFF`) has a contrast ratio of ~17:1. At `opacity: 0.55`, effective contrast drops to ~9:1, which still passes WCAG AA (4.5:1 minimum). Safe.
+
+### 4. Confirmation Dialog (FR-007)
+
+**Decision**: Custom modal component (reusing the existing `BottomSheet.vue` pattern) rather than `window.confirm()`.
+
+**Rationale**: `window.confirm()` is blocking, non-stylable, and inconsistent across browsers. A custom dialog matches the app's design system and provides a better UX. The existing `BottomSheet.vue` already handles teleportation, focus trapping, and Escape-key dismissal — the confirm dialog can reuse this or follow the same pattern.
+
+**Implementation approach**:
+- Create a `ConfirmDialog.vue` component
+- Props: `open`, `title`, `message`, `confirmLabel`, `cancelLabel`
+- Emits: `confirm`, `cancel`
+- Uses the same teleport-to-body pattern as `BottomSheet.vue`
+- Focus trapping and keyboard navigation (Tab, Escape, Enter)
+
+### 5. localStorage Validation (FR-010)
+
+**Decision**: Validate entries during read — filter out invalid events silently.
+
+**Rationale**: The spec says "silently excluded from the list." The `readEvents()` function already handles parse errors with a try/catch. We need to add field-level validation: an event is valid only if it has `eventToken`, `title`, and `dateTime` (all non-empty strings).
+
+**Implementation approach**:
+- Add a `isValidStoredEvent(e: unknown): e is StoredEvent` type guard
+- Apply it in `getStoredEvents()` as a filter
+- Invalid entries remain in localStorage (no destructive cleanup) but are not displayed
+
+### 6. FAB Placement (FR-011)
+
+**Decision**: Fixed-position button at bottom-right with safe-area padding.
+
+**Rationale**: Standard Material Design pattern for primary actions. The existing `RsvpBar.vue` already uses `padding-bottom: env(safe-area-inset-bottom)` for mobile notch avoidance — reuse the same approach.
+
+**Implementation approach**:
+- `position: fixed; bottom: calc(1.2rem + env(safe-area-inset-bottom)); right: 1.2rem`
+- Circular button with `+` icon, accent color background
+- `z-index` above content, shadow for elevation
+- Navigates to `/create` on click
+
+### 7. Event Sorting (FR-004)
+
+**Decision**: Sort in-memory after reading from localStorage.
+
+**Rationale**: The list is small (<100 events typically). Sorting on every render is negligible. Sort by `dateTime` ascending (nearest upcoming first), then past events after.
+
+**Implementation approach**:
+- Split events into `upcoming` (dateTime >= now) and `past` (dateTime < now)
+- Sort upcoming ascending (soonest first), past descending (most recent past first)
+- Concatenate: `[...upcoming, ...past]`
+
+### 8. Role Distinction (FR-008 / US-5)
+
+**Decision**: Small badge/label on the event card indicating "Organizer" or "Attendee."
+
+**Rationale**: The data is already available — `organizerToken` present means organizer, `rsvpToken` present (without `organizerToken`) means attendee. A subtle text badge is sufficient; no need for icons or colors.
+
+**Implementation approach**:
+- If `organizerToken` is set → show "Organizer" badge (accent-colored)
+- If `rsvpToken` is set (no `organizerToken`) → show "Attendee" badge (muted)
+- If neither → show no badge (edge case: event stored but no role — could happen with manual localStorage manipulation)
