Merge pull request 'Add Open Graph and Twitter Card meta-tags for link previews' (#24) from 012-link-preview into master

Replace PathResourceResolver SPA fallback with SpaController that
injects OG/Twitter meta-tags into cached index.html template.
Event pages get event-specific tags (title, date, location),
all other pages get generic fete branding. Includes og-image.png
brand asset and forward-headers-strategy for proxy support.

 	* Frontend: Vue 3 (mit Vite als Bundler, TypeScript, Vue Router)
 * Architekturentscheidungen die NOCH NICHT getroffen wurden (hier darf nichts eigenmächtig entschieden werden!):
 	* (derzeit keine offenen Architekturentscheidungen)
+
+## 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 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
+* 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
+

-# 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.*
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| I. Privacy by Design | ✅ PASS | Purely client-side. No data leaves the browser. No analytics. |
+| II. Test-Driven Methodology | ✅ PASS | Unit tests for composable, E2E for each user story. TDD enforced. |
+| III. API-First Development | ✅ N/A | No API changes — this feature reads only from localStorage. |
+| IV. Simplicity & Quality | ✅ PASS | Minimal approach: extend existing composable + new components. No over-engineering. |
+| V. Dependency Discipline | ✅ PASS | No new dependencies. Swipe gesture implemented with native Touch API. Relative time via built-in `Intl.RelativeTimeFormat`. |
+| VI. Accessibility | ✅ PASS | Semantic list markup, ARIA labels, keyboard navigation, WCAG AA contrast on faded past events. |
+
+**Gate result: PASS** — no violations.

+# 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)

+# Feature Specification: Event List on Home Page
+
+**Feature Branch**: `009-list-events`
+**Created**: 2026-03-08
+**Status**: Draft
+**Input**: User description: "man kann auf der hauptseite eine liste an events sehen, sofern sie im localstorage gespeichert sind"
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - View My Events (Priority: P1)
+
+As a returning user, I want to see a list of events I have previously created or interacted with (RSVP'd to) on the home page, so I can quickly navigate back to them without needing to remember or bookmark individual event links.
+
+The home page displays all events stored in the browser's local storage. Each event entry shows the event title and date/time. Tapping an event navigates to its detail page.
+
+**Why this priority**: This is the core value of the feature — without the list, the home page remains a dead end for returning users.
+
+**Independent Test**: Can be fully tested by creating an event (or simulating localStorage entries), returning to the home page, and verifying all stored events appear in a list with correct titles and dates.
+
+**Acceptance Scenarios**:
+
+1. **Given** the user has 3 events stored in localStorage, **When** they visit the home page, **Then** all 3 events are displayed in a list showing title and date/time for each.
+2. **Given** the user has events stored in localStorage, **When** they tap on an event in the list, **Then** they are navigated to the event detail page (`/events/:eventToken`).
+3. **Given** the user has events stored in localStorage, **When** they visit the home page, **Then** events are sorted by date/time (nearest upcoming event first, past events last).
+
+---
+
+### User Story 2 - Empty State (Priority: P2)
+
+As a new user with no stored events, I see an inviting empty state on the home page that encourages me to create my first event or explains how to get started.
+
+**Why this priority**: First-time users need clear guidance. The empty state is the first impression for new users.
+
+**Independent Test**: Can be tested by clearing localStorage and visiting the home page — the empty state message and "Create Event" call-to-action should be visible.
+
+**Acceptance Scenarios**:
+
+1. **Given** no events are stored in localStorage, **When** the user visits the home page, **Then** an empty state message is displayed (e.g., "No events yet") with a prominent "Create Event" button.
+2. **Given** the user has at least one event stored, **When** they visit the home page, **Then** the empty state message is not shown — the event list is displayed instead.
+
+---
+
+### User Story 3 - Remove Event from List (Priority: P3)
+
+As a user, I want to remove an event from my personal list so I can keep my home page tidy and only show events I still care about.
+
+**Why this priority**: Housekeeping capability. Without removal, the list grows indefinitely and becomes cluttered over time.
+
+**Independent Test**: Can be tested by having multiple events in localStorage, removing one from the list, and verifying it disappears from the home page while the others remain.
+
+**Acceptance Scenarios**:
+
+1. **Given** the user has events in their list, **When** they tap the delete icon on an event card, **Then** a confirmation prompt appears asking if they are sure.
+1b. **Given** the user has events in their list, **When** they swipe an event card to the left, **Then** a confirmation prompt appears asking if they are sure.
+2. **Given** the confirmation prompt is shown, **When** the user confirms removal, **Then** the event is removed from localStorage and disappears from the list immediately.
+3. **Given** the confirmation prompt is shown, **When** the user cancels, **Then** the event remains in the list unchanged.
+
+---
+
+### User Story 4 - Past Events Appear Faded (Priority: P2)
+
+As a user, I want events whose date/time has passed to appear visually faded or muted in the list, so I can immediately focus on upcoming events without past events cluttering my attention.
+
+The fading should feel modern and polished — not a blunt grey-out, but a subtle reduction in contrast and saturation that makes past events recede visually while remaining readable and tappable.
+
+**Why this priority**: Without this, past and upcoming events look identical, making the list harder to scan. This is essential for usability once a user has accumulated several events.
+
+**Independent Test**: Can be tested by having both future and past events in localStorage and verifying that past events display with reduced visual prominence while remaining interactive.
+
+**Acceptance Scenarios**:
+
+1. **Given** the user has a past event (dateTime before now) in localStorage, **When** they view the home page, **Then** the event appears with reduced visual prominence (muted colors, lower contrast) compared to upcoming events.
+2. **Given** the user has a past event in the list, **When** they tap on it, **Then** it still navigates to the event detail page — it remains fully interactive.
+3. **Given** the user has both past and upcoming events, **When** they view the home page, **Then** upcoming events appear first (full visual prominence), followed by past events (faded), creating a clear visual hierarchy.
+
+---
+
+### User Story 5 - Visual Distinction for Event Roles (Priority: P3)
+
+As a user, I want to see at a glance whether I am the organizer of an event or just an attendee, so I can quickly identify my responsibilities.
+
+**Why this priority**: Nice-to-have clarity. The data is already available in localStorage (presence of `organizerToken`), so surfacing it improves usability at low effort.
+
+**Independent Test**: Can be tested by having both created events (with organizerToken) and RSVP'd events (with rsvpToken) in localStorage, and verifying they display different visual indicators.
+
+**Acceptance Scenarios**:
+
+1. **Given** the user has a created event (organizerToken present) in localStorage, **When** they view the home page, **Then** the event shows a visual indicator marking them as the organizer (e.g., a badge or label).
+2. **Given** the user has an event with an RSVP (rsvpToken present, no organizerToken) in localStorage, **When** they view the home page, **Then** the event shows a visual indicator marking them as an attendee.
+
+---
+
+### Edge Cases
+
+- What happens when localStorage data is corrupted or contains invalid entries? Events with missing required fields (eventToken, title, dateTime) are silently excluded from the list.
+- What happens when localStorage is unavailable (e.g., private browsing with storage disabled)? The empty state is shown with the "Create Event" button — the app remains functional.
+- What happens when an event's date/time has passed? The event remains in the list but appears visually faded.
+- What happens when the user has a very large number of stored events (e.g., 50+)? The list scrolls naturally. No pagination is needed at this scale since localStorage entries are lightweight.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST display a list of all events stored in the browser's local storage on the home page.
+- **FR-002**: Each event entry MUST show the event title and the event date/time displayed as a relative time label (e.g., "in 3 days", "yesterday") using `Intl.RelativeTimeFormat`.
+- **FR-003**: Each event entry MUST be tappable/clickable and navigate to the event detail page (`/events/:eventToken`).
+- **FR-004**: Events MUST be sorted by date/time with nearest upcoming events first and past events last.
+- **FR-005**: System MUST display an empty state with a "Create Event" call-to-action when no events are stored.
+- **FR-006a**: Users MUST be able to remove individual events from their local list via a visible delete icon on each event card (primary mechanism, implemented first).
+- **FR-006b**: Users MUST be able to remove individual events via swipe-to-delete gesture (secondary mechanism, implemented separately after FR-006a).
+- **FR-007**: System MUST show a confirmation prompt before removing an event from the list.
+- **FR-008**: System MUST visually distinguish events where the user is the organizer from events where the user is an attendee.
+- **FR-009**: System MUST display past events (dateTime before current time) with reduced visual prominence — muted colors and lower contrast — while keeping them readable and interactive.
+- **FR-010**: System MUST gracefully handle corrupted or incomplete localStorage entries by excluding invalid events from the list.
+- **FR-011**: The "Create Event" button MUST remain accessible on the home page even when events are listed, implemented as a Floating Action Button (FAB) fixed at the bottom-right corner.
+
+### Key Entities
+
+- **Stored Event**: A locally persisted reference to an event the user has interacted with. Contains: event token (unique identifier for navigation), title, date/time, expiry date, and optionally an organizer token (if created by this user) or RSVP token and name (if the user RSVP'd).
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: Users can see all their stored events on the home page within 1 second of page load.
+- **SC-002**: Users can navigate from the home page to any event detail page in a single tap/click.
+- **SC-003**: Users can remove an unwanted event from their list in under 3 seconds (including confirmation).
+- **SC-004**: New users (no stored events) see a clear call-to-action to create their first event.
+- **SC-005**: Users can distinguish their role (organizer vs. attendee) for each event at a glance without opening the event.
+
+## Clarifications
+
+### Session 2026-03-08
+
+- Q: How does the user trigger event removal? → A: Two mechanisms — visible delete icon on each event card (primary, implemented first) and swipe-to-delete gesture (secondary, implemented separately after).
+- Q: Placement of "Create Event" button when events exist? → A: Floating Action Button (FAB) fixed at bottom-right corner.
+- Q: Date/time display format in event list? → A: Relative time labels ("in 3 days", "yesterday") via Intl.RelativeTimeFormat.
+
+## Assumptions
+
+- The existing `useEventStorage` composable and `StoredEvent` interface provide all necessary data for the event list (no backend API calls needed for listing).
+- The event list is purely client-side — there is no server-side "my events" endpoint. Privacy is preserved because events are only known to the user's browser.
+- The event list uses `Intl.RelativeTimeFormat` for relative time labels (FR-002), while the event detail view uses `Intl.DateTimeFormat` for absolute date/time display. Both use the browser's locale (`navigator.language`).
+- The "Create Event" flow (spec 006) already saves events to localStorage, so no changes to event creation are needed.
+- The RSVP flow (spec 008) already saves RSVP data to localStorage, so no changes to RSVP are needed.

+# Tasks: Event List on Home Page
+
+**Input**: Design documents from `/specs/009-list-events/`
+**Prerequisites**: plan.md, spec.md, research.md, data-model.md
+
+**Tests**: Unit tests (Vitest) and E2E tests (Playwright) are included per constitution (Principle II: Test-Driven Methodology).
+
+**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.
+
+## 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, US3)
+- Include exact file paths in descriptions
+
+---
+
+## Phase 1: Setup (Shared Infrastructure)
+
+**Purpose**: Composable extensions and utility functions shared across all user stories
+
+- [x] T000 Rename router param `:token` to `:eventToken` in `frontend/src/router/index.ts` and update all references in `EventDetailView.vue`, `EventStubView.vue`, and their test files (consistency with `StoredEvent.eventToken` field name)
+- [x] T001 Add `isValidStoredEvent` type guard and validation filter to `frontend/src/composables/useEventStorage.ts` (FR-010)
+- [x] T002 Add `removeEvent(eventToken: string)` function to `frontend/src/composables/useEventStorage.ts` (needed by US3)
+- [x] T003 [P] Create `useRelativeTime` composable in `frontend/src/composables/useRelativeTime.ts` (Intl.RelativeTimeFormat wrapper, FR-002)
+- [x] T004 [P] Add unit tests for `isValidStoredEvent` and `removeEvent` in `frontend/src/composables/__tests__/useEventStorage.spec.ts`
+- [x] T005 [P] Create unit tests for `useRelativeTime` in `frontend/src/composables/__tests__/useRelativeTime.spec.ts`
+
+**Checkpoint**: Composable layer complete — all shared logic tested and available for components.
+
+---
+
+## Phase 2: User Story 1 — View My Events (Priority: P1) 🎯 MVP
+
+**Goal**: Home page shows all stored events in a sorted list with title and relative time. Tapping navigates to event detail.
+
+**Independent Test**: Simulate localStorage entries, visit home page, verify all events appear sorted with correct titles and relative times. Tap an event and verify navigation to `/events/:eventToken`.
+
+### Unit Tests for User Story 1
+
+- [x] T006 [P] [US1] Create unit tests for EventCard component in `frontend/src/components/__tests__/EventCard.spec.ts` — include test cases for `isPast` prop (faded styling) and role badge rendering (organizer vs. attendee)
+- [x] T007 [P] [US1] Create unit tests for EventList component in `frontend/src/components/__tests__/EventList.spec.ts`
+
+### Implementation for User Story 1
+
+- [x] T008 [P] [US1] Create `EventCard.vue` component in `frontend/src/components/EventCard.vue` — displays title, relative time, role badge; emits click for navigation
+- [x] T009 [US1] Create `EventList.vue` component in `frontend/src/components/EventList.vue` — reads events from composable, validates, sorts (upcoming asc, past desc), renders EventCard list
+- [x] T010 [US1] Refactor `HomeView.vue` in `frontend/src/views/HomeView.vue` — integrate EventList, conditionally show list when events exist
+- [x] T011 [US1] Add event card and list styles to `frontend/src/assets/main.css`
+
+### E2E Tests for User Story 1
+
+- [x] T012 [US1] Create E2E test file `frontend/e2e/home-events.spec.ts` — tests: events displayed with title and relative time, sorted correctly, click navigates to detail page
+
+**Checkpoint**: MVP complete — returning users see their events and can navigate to details.
+
+---
+
+## Phase 3: User Story 2 — Empty State (Priority: P2)
+
+**Goal**: New users with no stored events see an inviting empty state with a "Create Event" call-to-action.
+
+**Independent Test**: Clear localStorage, visit home page, verify empty state message and "Create Event" button are visible.
+
+### Unit Tests for User Story 2
+
+- [x] T013 [P] [US2] Create unit tests for EmptyState component in `frontend/src/components/__tests__/EmptyState.spec.ts`
+
+### Implementation for User Story 2
+
+- [x] T014 [US2] Create `EmptyState.vue` component in `frontend/src/components/EmptyState.vue` — shows message and "Create Event" RouterLink
+- [x] T015 [US2] Update `HomeView.vue` in `frontend/src/views/HomeView.vue` — show EmptyState when no valid events, show EventList otherwise
+- [x] T016 [US2] Add empty state styles to `frontend/src/assets/main.css`
+
+### E2E Tests for User Story 2
+
+- [x] T017 [US2] Add E2E tests to `frontend/e2e/home-events.spec.ts` — tests: empty state shown when no events, hidden when events exist
+
+**Checkpoint**: Home page handles both new and returning users.
+
+---
+
+## Phase 4: User Story 4 — Past Events Appear Faded (Priority: P2)
+
+**Goal**: Events whose date/time has passed appear with reduced visual prominence (muted colors, lower contrast) while remaining interactive.
+
+**Independent Test**: Have both future and past events in localStorage, verify past events display faded while remaining clickable.
+
+### Implementation for User Story 4
+
+- [x] T018 [US4] Add `.event-card--past` modifier class with `opacity: 0.6; filter: saturate(0.5)` to `frontend/src/components/EventCard.vue` or `frontend/src/assets/main.css`
+- [x] T019 [US4] Pass `isPast` computed property to EventCard in `EventList.vue` and apply modifier class in `frontend/src/components/EventCard.vue`
+
+### E2E Tests for User Story 4
+
+- [x] T020 [US4] Add E2E tests to `frontend/e2e/home-events.spec.ts` — tests: past events have faded class, upcoming events do not, past events remain clickable
+
+**Checkpoint**: Visual hierarchy distinguishes upcoming from past events.
+
+---
+
+## Phase 5: User Story 3 — Remove Event from List (Priority: P3)
+
+**Goal**: Users can remove events from their local list via delete icon (and later swipe) with confirmation.
+
+**Independent Test**: Have multiple events, remove one via delete icon, verify it disappears while others remain.
+
+### Unit Tests for User Story 3
+
+- [x] T021 [P] [US3] Create unit tests for ConfirmDialog component in `frontend/src/components/__tests__/ConfirmDialog.spec.ts`
+
+### Implementation for User Story 3
+
+- [x] T022 [US3] Create `ConfirmDialog.vue` component in `frontend/src/components/ConfirmDialog.vue` — teleport-to-body modal with confirm/cancel, focus trapping, Escape key
+- [x] T023 [US3] Add delete icon button to `EventCard.vue` in `frontend/src/components/EventCard.vue` — emits `delete` event with eventToken (FR-006a)
+- [x] T024 [US3] Wire delete flow in `EventList.vue` in `frontend/src/components/EventList.vue` — listen for delete event, show ConfirmDialog, call `removeEvent()` on confirm
+- [x] T025 [US3] Add delete icon and confirm dialog styles to `frontend/src/assets/main.css`
+
+### E2E Tests for User Story 3
+
+- [x] T026 [US3] Add E2E tests to `frontend/e2e/home-events.spec.ts` — tests: delete icon visible, confirmation dialog appears, confirm removes event, cancel keeps event
+
+**Checkpoint**: Users can manage their event list.
+
+---
+
+## Phase 6: User Story 5 — Visual Distinction for Event Roles (Priority: P3)
+
+**Goal**: Events show a badge indicating whether the user is the organizer or an attendee.
+
+**Independent Test**: Have events with organizerToken and rsvpToken in localStorage, verify different badges displayed.
+
+### Implementation for User Story 5
+
+- [x] T027 [US5] Add role badge (Organizer/Attendee) to `EventCard.vue` in `frontend/src/components/EventCard.vue` — derive from organizerToken/rsvpToken presence
+- [x] T028 [US5] Add role badge styles to `frontend/src/assets/main.css`
+
+### E2E Tests for User Story 5
+
+- [x] T029 [US5] Add E2E tests to `frontend/e2e/home-events.spec.ts` — tests: organizer badge shown for events with organizerToken, attendee badge for events with rsvpToken only
+
+**Checkpoint**: Role distinction visible at a glance.
+
+---
+
+## Phase 7: Polish & Cross-Cutting Concerns
+
+**Purpose**: FAB, swipe gesture, accessibility, and final polish
+
+- [x] T030 Create `CreateEventFab.vue` in `frontend/src/components/CreateEventFab.vue` — fixed FAB at bottom-right, navigates to `/create` (FR-011)
+- [x] T031 Add FAB to `HomeView.vue` in `frontend/src/views/HomeView.vue` — visible when events exist (empty state has its own CTA)
+- [x] T032 Add FAB styles to `frontend/src/assets/main.css`
+- [x] T033 Implement swipe-to-delete gesture on EventCard in `frontend/src/components/EventCard.vue` — native Touch API (FR-006b)
+- [x] T034 Accessibility review: verify ARIA labels, keyboard navigation (Tab/Enter/Escape), focus trapping in ConfirmDialog, WCAG AA contrast on faded cards
+- [x] T035 Add E2E tests for FAB to `frontend/e2e/home-events.spec.ts` — tests: FAB visible when events exist, navigates to create page
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Phase 1 (Setup)**: No dependencies — start immediately
+- **Phase 2 (US1)**: Depends on T001, T003 (validation + relative time composable)
+- **Phase 3 (US2)**: Depends on T001 (validation); can run in parallel with US1
+- **Phase 4 (US4)**: Depends on Phase 2 completion (EventCard must exist)
+- **Phase 5 (US3)**: Depends on Phase 2 completion (EventList must exist) + T002 (removeEvent)
+- **Phase 6 (US5)**: Depends on Phase 2 completion (EventCard must exist)
+- **Phase 7 (Polish)**: Depends on Phases 2–6 completion
+
+### User Story Dependencies
+
+- **US1 (P1)**: Depends only on Phase 1 — no other story dependencies
+- **US2 (P2)**: Depends only on Phase 1 — independent of US1 but shares HomeView
+- **US4 (P2)**: Depends on US1 (extends EventCard with past styling)
+- **US3 (P3)**: Depends on US1 (extends EventList with delete flow)
+- **US5 (P3)**: Depends on US1 (extends EventCard with role badge)
+
+### Parallel Opportunities
+
+- T003 + T004 + T005 can all run in parallel (different files)
+- T006 + T007 can run in parallel (different test files)
+- T008 can run in parallel with T006/T007 (component vs test files)
+- US4, US5 can start in parallel once US1 is done (both extend EventCard independently)
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup composables
+2. Complete Phase 2: US1 — EventCard, EventList, HomeView refactor
+3. **STOP and VALIDATE**: Test the event list end-to-end
+4. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Phase 1 → Composable layer ready
+2. Phase 2 (US1) → Event list works → MVP!
+3. Phase 3 (US2) → Empty state for new users
+4. Phase 4 (US4) → Past events faded
+5. Phase 5 (US3) → Remove events from list
+6. Phase 6 (US5) → Role badges
+7. Phase 7 → FAB, swipe, accessibility polish
+
+---
+
+## Notes
+
+- [P] tasks = different files, no dependencies
+- [Story] label maps task to specific user story for traceability
+- This is a **frontend-only** feature — no backend changes needed
+- All data comes from existing `useEventStorage` composable (localStorage)
+- E2E tests consolidated in single file `home-events.spec.ts` with separate `describe` blocks per story

-# Feature Specification: Edit Event Details as Organizer
-
-**Feature**: `010-edit-event`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md
-
-## User Scenarios & Testing
-
-### User Story 1 - Edit event details (Priority: P1)
-
-The event organizer wants to update the details of an event they created — title, description, date/time, location, or expiry date — so that guests always see accurate and up-to-date information if something changes.
-
-**Why this priority**: Core organizer capability. Edits are expected for any real-world event (date changes, venue updates). Without this, the organizer has no recourse when details change after creation.
-
-**Independent Test**: Can be fully tested by creating an event (US-1), navigating to the edit form, submitting changed values, and verifying the event page reflects the updates.
-
-**Acceptance Scenarios**:
-
-1. **Given** an organizer on the event page with a valid organizer token in localStorage, **When** they navigate to the edit form, **Then** the form is pre-filled with the current event values (title, description, date/time, location, expiry date).
-2. **Given** the edit form is pre-filled, **When** the organizer modifies one or more fields and submits, **Then** the changes are persisted server-side and the organizer is returned to the event page which reflects the updated details.
-3. **Given** the organizer is on the event page without an organizer token in localStorage, **When** they attempt to access the edit UI, **Then** no edit option is shown and the server rejects any update request.
-
----
-
-### User Story 2 - Expiry date future-date validation (Priority: P2)
-
-When editing, the organizer must set the expiry date to a future date. Setting it to today or a past date is rejected, and the organizer is directed to the delete feature (US-19) if they want to remove the event immediately.
-
-**Why this priority**: Enforces the invariant that an event's expiry date is always in the future. Prevents the expiry date field from being misused as an implicit deletion mechanism, keeping the model clean.
-
-**Independent Test**: Can be tested by submitting the edit form with a past or current date in the expiry date field and verifying the rejection response and validation message.
-
-**Acceptance Scenarios**:
-
-1. **Given** the edit form is open, **When** the organizer sets the expiry date to today or a past date and submits, **Then** the submission is rejected with a clear validation message directing the organizer to use the delete feature (US-19) instead.
-2. **Given** the edit form is open, **When** the organizer sets the expiry date to a date in the future and submits, **Then** the change is accepted and persisted.
-
----
-
-### User Story 3 - Organizer token authentication (Priority: P2)
-
-If the organizer token is absent or invalid, neither the edit UI is shown nor the edit request is accepted server-side.
-
-**Why this priority**: Security constraint — the organizer token is the sole authentication mechanism. Both client and server must enforce it independently.
-
-**Independent Test**: Can be tested by attempting an edit request with a missing or wrong organizer token and verifying a 403/401 response and no UI exposure.
-
-**Acceptance Scenarios**:
-
-1. **Given** a visitor without an organizer token in localStorage for the event, **When** they view the event page, **Then** no edit option or link is shown.
-2. **Given** an edit request is submitted with an absent or invalid organizer token, **When** the server processes the request, **Then** it rejects the request and the event data is unchanged.
-
----
-
-### Edge Cases
-
-- What happens when the organizer submits the edit form with no changes? The server accepts the submission (idempotent update) and the organizer is returned to the event page.
-- What happens if the title field is left empty? Submission is rejected with a validation message — title is required.
-- What happens if the event has expired before the organizer submits the edit form? The server rejects the edit — editing an expired event is not permitted.
-- How does the system handle concurrent edits (e.g. organizer edits from two devices simultaneously)? [NEEDS EXPANSION — last-write-wins is the simplest strategy]
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: System MUST allow the organizer to edit: title (required), description (optional), date and time (required), location (optional), expiry date (required).
-- **FR-002**: System MUST pre-fill the edit form with the current stored values for all editable fields.
-- **FR-003**: System MUST reject an edit submission where the expiry date is today or in the past, and MUST return a validation message directing the organizer to use the delete feature (US-19).
-- **FR-004**: System MUST persist all submitted changes server-side upon successful validation.
-- **FR-005**: System MUST redirect the organizer to the event page after a successful edit, with the updated details visible.
-- **FR-006**: System MUST NOT expose the edit UI to any visitor who does not have a valid organizer token for the event in localStorage.
-- **FR-007**: System MUST reject any edit request where the organizer token is absent or does not match the event's stored organizer token.
-- **FR-008**: No account or additional authentication step beyond the organizer token is required to edit an event.
-
-### Key Entities
-
-- **Event**: Mutable entity with fields: title, description, date/time, location, expiry date. Identified externally by its event token. Updated via the organizer token.
-- **Organizer token**: Secret UUID stored in localStorage on the device where the event was created. Required to authenticate all organizer operations including editing.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: An organizer can update any editable field and see the change reflected on the public event page without a page reload after redirect.
-- **SC-002**: Any attempt to set the expiry date to a non-future date is rejected with a user-visible validation message before the server persists the change.
-- **SC-003**: No edit operation is possible — client or server — without a valid organizer token.
-- **SC-004**: The edit form is never shown to a visitor who does not hold the organizer token for the event.
-- **SC-005**: Visual highlighting of changed fields for guests is deferred to US-9 (Highlight changed event details); this story covers only the server-side persistence and organizer UX of editing.

+| `expiryDate` | `string` | ISO 8601 expiry date |
+| `rsvpToken` | `string?` | Present if user has RSVP'd |
+| `rsvpName` | `string?` | Name used for RSVP |
+
+**Note**: No changes to `StoredEvent`. The `dateTime` field is the sole input for all grouping and sorting logic.
+
+## New Types (frontend only)
+
+### SectionKey
+
+```typescript
+type SectionKey = 'today' | 'thisWeek' | 'later' | 'past'
+```
+
+Enum-like union type for the four temporal sections. Ordering is fixed: today → thisWeek → later → past.
+
+### EventSection
+
+```typescript
+interface EventSection {
+  key: SectionKey
+  label: string          // Display label: "Today", "This Week", "Later", "Past"
+  dateGroups: DateGroup[]
+  emphasized: boolean    // true only for 'today' section
+}
+```
+
+Represents one temporal section in the grouped list. Sections with no events are omitted entirely (never constructed).
+
+### DateGroup
+
+```typescript
+interface DateGroup {
+  dateKey: string        // YYYY-MM-DD (for keying/dedup)
+  label: string          // Formatted via Intl.DateTimeFormat, e.g., "Wed, 12 Mar"
+  events: StoredEvent[]  // Events on this date, sorted by time
+  showSubheader: boolean // false for "Today" section (FR-005)
+}
+```
+
+Groups events within a section by their specific calendar date. The `showSubheader` flag controls whether the date subheader is rendered (always false in "Today" section per FR-005).
+
+## Grouping Algorithm
+
+```
+Input: StoredEvent[], now: Date
+Output: EventSection[]
+
+1. Compute boundaries:
+   - startOfToday = today at 00:00:00 local
+   - endOfToday = today at 23:59:59.999 local
+   - endOfWeek = next Sunday at 23:59:59.999 local (or today if today is Sunday)
+
+2. Classify each event by dateTime:
+   - dateTime < startOfToday → "past"
+   - startOfToday ≤ dateTime ≤ endOfToday → "today"
+   - endOfToday < dateTime ≤ endOfWeek → "thisWeek"
+   - dateTime > endOfWeek → "later"
+
+3. Within each section, group by calendar date (YYYY-MM-DD)
+
+4. Sort:
+   - today/thisWeek/later: date groups ascending, events within group ascending by time
+   - past: date groups descending, events within group descending by time
+
+5. Emit only non-empty sections in fixed order: today, thisWeek, later, past
+```
+
+## State Transitions
+
+None. Events are static data in localStorage. Temporal classification is computed on each render based on current time. No event mutation occurs.
+
+## Validation Rules
+
+No new validation. Existing `isValidStoredEvent()` in `useEventStorage.ts` already validates the `dateTime` field as a parseable ISO 8601 string.

+# Implementation Plan: Event List Temporal Grouping
+
+**Branch**: `010-event-list-grouping` | **Date**: 2026-03-08 | **Spec**: `specs/010-event-list-grouping/spec.md`
+**Input**: Feature specification from `/specs/010-event-list-grouping/spec.md`
+
+## Summary
+
+Extend the existing flat event list with temporal section grouping (Today, This Week, Later, Past). The feature is purely client-side: the existing `EventList.vue` computed property that separates events into upcoming/past is refactored into a four-section grouping with section headers, date subheaders, and context-aware time formatting. No backend changes, no new dependencies.
+
+## Technical Context
+
+**Language/Version**: TypeScript 5.9 (frontend only)
+**Primary Dependencies**: Vue 3, Vue Router 5 (existing — no additions)
+**Storage**: localStorage via `useEventStorage.ts` composable (existing — no changes)
+**Testing**: Vitest (unit), Playwright + MSW (E2E)
+**Target Platform**: PWA, mobile-first, all modern browsers
+**Project Type**: Web application (frontend enhancement)
+**Performance Goals**: Grouping computation < 1ms for 100 events (trivial — single array pass)
+**Constraints**: Client-side only, no additional network requests, offline-capable
+**Scale/Scope**: Typically < 50 events per user in localStorage
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| I. Privacy by Design | PASS | No new data collection. Grouping uses existing `dateTime` field. No external services. |
+| II. Test-Driven Methodology | PASS | Unit tests for grouping logic + E2E tests for all user stories planned. TDD enforced. |
+| III. API-First Development | N/A | No API changes — purely frontend enhancement. |
+| IV. Simplicity & Quality | PASS | Minimal new code: one composable for grouping, template changes in EventList. No over-engineering. |
+| V. Dependency Discipline | PASS | No new dependencies. Uses browser `Intl` API and existing `Date` methods. |
+| VI. Accessibility | PASS | Section headers use semantic HTML (`<h2>`/`<h3>`), ARIA landmarks, keyboard navigable. WCAG AA contrast enforced. |
+
+**Gate result: PASS** — no violations.

+# Research: Event List Temporal Grouping
+
+**Feature**: 010-event-list-grouping | **Date**: 2026-03-08
+
+## 1. Week Boundary Calculation
+
+**Decision**: Use ISO 8601 week convention (Monday = first day of week). "This Week" spans from tomorrow through Sunday of the current week.
+
+**Rationale**: The spec explicitly states "ISO convention where Monday is the first day of the week" (Assumptions section). The browser's `Date.getDay()` returns 0 for Sunday, 1 for Monday — straightforward to compute end-of-week as next Sunday 23:59:59.
+
+**Implementation**: Compare event date against:
+- `startOfToday` and `endOfToday` for "Today"
+- `startOfTomorrow` and `endOfSunday` for "This Week"
+- `after endOfSunday` for "Later"
+- `before startOfToday` for "Past"
+
+Edge case (spec scenario 4): On Sunday, "This Week" is empty (tomorrow is already next week Monday), so events for Monday appear under "Later". This falls out naturally from the algorithm.
+
+**Alternatives considered**:
+- Using a date library (date-fns, luxon): Rejected — dependency discipline (Constitution V). Native `Date` + `Intl` is sufficient for this logic.
+- Locale-dependent week start: Rejected — spec mandates ISO convention explicitly.
+
+## 2. Date Formatting for Subheaders
+
+**Decision**: Use `Intl.DateTimeFormat` with `{ weekday: 'short', day: 'numeric', month: 'short' }` to produce labels like "Wed, 12 Mar".
+
+**Rationale**: Consistent with existing use of `Intl.RelativeTimeFormat` in `useRelativeTime.ts`. Respects user locale for month/weekday names. No external dependency needed.
+
+**Alternatives considered**:
+- Hardcoded English day/month names: Rejected — the project already uses `Intl` APIs for locale awareness.
+- Full date format (e.g., "Wednesday, March 12, 2026"): Rejected — too long for mobile cards.
+
+## 3. Time Display on Event Cards
+
+**Decision**: Add a `timeDisplayMode` prop to `EventCard.vue` with two modes:
+- `'clock'`: Shows formatted time (e.g., "18:30") using `Intl.DateTimeFormat` with `{ hour: '2-digit', minute: '2-digit' }`
+- `'relative'`: Shows relative time (e.g., "3 days ago") using existing `formatRelativeTime()`
+
+**Rationale**: Spec requires different time representations per section: clock time for Today/This Week/Later, relative time for Past. A prop-driven approach keeps EventCard stateless regarding section context.
+
+**Alternatives considered**:
+- EventCard determining its own display mode: Rejected — card shouldn't know about sections; parent owns that context.
+- Passing a pre-formatted string: Viable but less type-safe. A mode enum is clearer.
+
+## 4. Grouping Data Structure
+
+**Decision**: The `useEventGrouping` composable returns an array of section objects:
+
+```typescript
+interface EventSection {
+  key: 'today' | 'thisWeek' | 'later' | 'past'
+  label: string  // "Today", "This Week", "Later", "Past"
+  events: GroupedEvent[]
+}
+
+interface DateGroup {
+  date: string       // ISO date string (YYYY-MM-DD) for keying
+  label: string      // Formatted date label (e.g., "Wed, 12 Mar")
+  events: StoredEvent[]
+}
+
+interface GroupedEvent extends StoredEvent {
+  dateGroup: string  // ISO date for sub-grouping
+}
+```
+
+Actually, simpler: the composable returns sections, each containing date groups, each containing events.
+
+```typescript
+interface EventSection {
+  key: 'today' | 'thisWeek' | 'later' | 'past'
+  label: string
+  dateGroups: DateGroup[]
+}
+
+interface DateGroup {
+  dateKey: string        // YYYY-MM-DD
+  label: string          // Formatted: "Wed, 12 Mar"
+  events: StoredEvent[]
+}
+```
+
+**Rationale**: Two-level grouping (section → date → events) matches the spec's hierarchy. Empty sections are simply omitted from the returned array (FR-002). The "Today" section still has one DateGroup but the template skips rendering its subheader (FR-005).
+
+**Alternatives considered**:
+- Flat list with section markers: Harder to template, mixes data and presentation.
+- Map/Record structure: Arrays preserve ordering guarantees (Today → This Week → Later → Past).
+
+## 5. Visual Emphasis for "Today" Section
+
+**Decision**: Apply a CSS class `.section--today` to the Today section that uses:
+- Slightly larger section header (font-weight: 800, font-size: 1.1rem vs 700/1rem for others)
+- A subtle left border accent using the primary gradient pink (`#F06292`)
+
+**Rationale**: Consistent with Electric Dusk design system. Subtle enough not to distract but visually distinct. The existing past-event fade (opacity: 0.6, saturate: 0.5) already handles the other end of the spectrum.
+
+**Alternatives considered**:
+- Background highlight: Could clash with card backgrounds on mobile.
+- Icon/emoji prefix: Spec doesn't mention icons; keep it typography-driven per design system.
+
+## 6. Accessibility Considerations
+
+**Decision**:
+- Section headers are `<h2>` elements
+- Date subheaders are `<h3>` elements
+- The event list container keeps its existing `role="list"`
+- Each section is a `<section>` element with `aria-label` matching the section label
+
+**Rationale**: Constitution VI requires semantic HTML and ARIA. The heading hierarchy (h2 > h3) provides screen reader navigation landmarks. The `<section>` element with label allows assistive technology to announce section boundaries.
+
+## 7. Existing Test Updates
+
+**Decision**:
+- Existing `EventList.spec.ts` unit tests will be updated to account for the new grouped structure (sections instead of flat list)
+- Existing `home-events.spec.ts` E2E tests will be extended with new scenarios for temporal grouping
+- New `useEventGrouping.spec.ts` tests the pure grouping function in isolation
+
+**Rationale**: TDD (Constitution II). The grouping logic is a pure function — ideal for thorough unit testing with various date combinations and edge cases.

+# Feature Specification: Event List Temporal Grouping
+
+**Feature Branch**: `010-event-list-grouping`
+**Created**: 2026-03-08
+**Status**: Draft
+**Input**: User description: "Extend the event list with temporal grouping so users know if an event is today, this week, or further in the future."
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Temporal Section Headers (Priority: P1)
+
+As a user viewing my event list, I want events grouped under clear date-based section headers so I can instantly see what's happening today, this week, and later without reading individual dates.
+
+The list displays events under these temporal sections (in order):
+
+1. **Today** — events happening today
+2. **This Week** — events from tomorrow through end of current week (Sunday)
+3. **Later** — upcoming events beyond this week
+4. **Past** — events that have already occurred
+
+Each section only appears if it contains at least one event. Empty sections are hidden entirely.
+
+**Why this priority**: The core value of this feature — temporal orientation at a glance. Without section headers, the rest of the feature has no foundation.
+
+**Independent Test**: Can be fully tested by adding events with various dates to localStorage and verifying they appear under the correct section headers.
+
+**Acceptance Scenarios**:
+
+1. **Given** a user has events today, tomorrow, next week, and last week, **When** they view the event list, **Then** they see four sections: "Today", "This Week", "Later", and "Past" with events correctly distributed.
+2. **Given** a user has only events for today, **When** they view the event list, **Then** only the "Today" section is visible — no empty sections appear.
+3. **Given** a user has no events at all, **When** they view the event list, **Then** the empty state is shown (as currently implemented).
+4. **Given** it is Sunday and an event is scheduled for Monday, **When** the user views the list, **Then** the Monday event appears under "Later" (not "This Week"), because the current week ends on Sunday.
+
+---
+
+### User Story 2 - Date Subheaders Within Sections (Priority: P2)
+
+Within each section (except "Today"), events are further grouped by their specific date with a subheader showing the formatted date (e.g., "Sat, 17 Sep"). This mirrors the inspiration layout where individual dates appear as smaller headings under the main temporal section.
+
+Within the "Today" section, no date subheader is needed since all events share the same date.
+
+**Why this priority**: Adds finer-grained orientation within sections — especially important when "This Week" or "Later" contain multiple events across different days.
+
+**Independent Test**: Can be tested by adding multiple events on different days within the same temporal section and verifying date subheaders appear.
+
+**Acceptance Scenarios**:
+
+1. **Given** a user has events on Wednesday and Friday of this week, **When** they view the "This Week" section, **Then** events are grouped under date subheaders like "Wed, 12 Mar" and "Fri, 14 Mar".
+2. **Given** a user has three events today, **When** they view the "Today" section, **Then** no date subheader appears — events are listed directly under the "Today" header.
+3. **Given** two events on the same future date, **When** the user views the list, **Then** both appear under a single date subheader for that day, sorted by time.
+
+---
+
+### User Story 3 - Enhanced Event Card Information (Priority: P2)
+
+Each event card within the grouped list shows time information relevant to its context:
+
+- **Today's events**: Show the time (e.g., "18:30") prominently, since the date is implied by the section.
+- **Future events**: Show the time (e.g., "18:30") — the date is provided by the subheader.
+- **Past events**: Continue showing relative time (e.g., "3 days ago") as currently implemented, since exact time matters less.
+
+The existing role badges (Organizer/Attendee) and event title remain as-is.
+
+**Why this priority**: Completes the information design — users need different time representations depending on temporal context.
+
+**Independent Test**: Can be tested by checking that event cards display the correct time format based on which section they appear in.
+
+**Acceptance Scenarios**:
+
+1. **Given** an event today at 18:30, **When** the user views the "Today" section, **Then** the card shows "18:30" (not "in 3 hours").
+2. **Given** an event on Friday at 10:00, **When** the user views it under "This Week", **Then** the card shows "10:00".
+3. **Given** a past event from 3 days ago, **When** the user views the "Past" section, **Then** the card shows "3 days ago" as it does currently.
+
+---
+
+### User Story 4 - Today Section Visual Emphasis (Priority: P3)
+
+The "Today" section header and its event cards receive subtle visual emphasis to draw the user's attention to what's happening now. This could be a slightly larger section header, bolder typography, or a subtle highlight — consistent with the Electric Dusk design system.
+
+Past events continue to appear visually faded (reduced opacity/saturation) as currently implemented.
+
+**Why this priority**: Nice visual polish that reinforces the temporal hierarchy, but the feature works without it.
+
+**Independent Test**: Can be verified visually by checking that the "Today" section stands out compared to other sections.
+
+**Acceptance Scenarios**:
+
+1. **Given** events exist for today and later, **When** the user views the list, **Then** the "Today" section is visually more prominent than other sections.
+2. **Given** only past events exist, **When** the user views the list, **Then** the "Past" section uses the existing faded treatment without any special emphasis.
+
+---
+
+### Edge Cases
+
+- What happens when the user's device clock is set incorrectly? Events may appear in the wrong section — this is acceptable, no special handling needed.
+- What happens at midnight when "today" changes? The grouping updates on next page load or navigation; real-time re-sorting is not required.
+- What happens with an event at exactly midnight (00:00)? It belongs to the day it falls on — same as any other time.
+- What happens when a section has many events (10+)? All events are shown; no pagination or truncation within sections.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST group events into temporal sections: "Today", "This Week", "Later", and "Past".
+- **FR-002**: System MUST hide sections that contain no events.
+- **FR-003**: System MUST display section headers with the temporal label (e.g., "Today", "This Week").
+- **FR-004**: System MUST display date subheaders within "This Week", "Later", and "Past" sections when events span multiple days.
+- **FR-005**: System MUST NOT display a date subheader within the "Today" section.
+- **FR-006**: System MUST sort events within each section by time ascending (earliest first) for upcoming events and by time descending (most recent first) for past events.
+- **FR-007**: System MUST display clock time (e.g., "18:30") on event cards in "Today", "This Week", and "Later" sections.
+- **FR-008**: System MUST display relative time (e.g., "3 days ago") on event cards in the "Past" section.
+- **FR-009**: System MUST visually emphasize the "Today" section compared to other sections.
+- **FR-010**: System MUST continue to fade past events visually (as currently implemented).
+- **FR-011**: System MUST preserve existing functionality: role badges, swipe-to-delete, delete confirmation, empty state.
+- **FR-012**: "This Week" MUST include events from tomorrow through the end of the current calendar week (Sunday).
+
+### Key Entities
+
+- **Temporal Section**: A grouping label ("Today", "This Week", "Later", "Past") that organizes events by their relationship to the current date.
+- **Date Subheader**: A formatted date label (e.g., "Sat, 17 Sep") that groups events within a temporal section by their specific date.
+- **StoredEvent**: Existing entity — no changes to its structure are required. The `dateTime` field is used for all grouping and sorting logic.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: Users can identify how many events they have today within 2 seconds of viewing the list.
+- **SC-002**: Every event in the list is assigned to exactly one temporal section — no event appears in multiple sections or is missing.
+- **SC-003**: Section ordering is always consistent: Today > This Week > Later > Past.
+- **SC-004**: The feature works entirely client-side with no additional network requests beyond what currently exists.
+- **SC-005**: All existing event list functionality (delete, navigation, role badges) continues to work unchanged.
+
+## Assumptions
+
+- The user's locale and timezone are used for determining "today" and formatting dates/times (via the browser's `Intl` API, consistent with existing approach).
+- "Week" follows ISO convention where Monday is the first day of the week. "This Week" runs from tomorrow through Sunday.
+- The design system (Electric Dusk + Sora) applies to all new visual elements. The inspiration screenshot's color theme is explicitly NOT adopted.
+- No backend changes are needed — this is a purely frontend enhancement to the existing client-side event list.

+# Tasks: Event List Temporal Grouping
+
+**Input**: Design documents from `/specs/010-event-list-grouping/`
+**Prerequisites**: plan.md, spec.md, research.md, data-model.md
+
+**Tests**: Included — spec.md references TDD (Constitution II), and research.md explicitly plans unit + E2E test updates.
+
+**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.
+
+## 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, US3)
+- Include exact file paths in descriptions
+
+---
+
+## Phase 1: Setup
+
+**Purpose**: No new project setup needed — this is a frontend-only enhancement to an existing codebase. Phase 1 is empty.
+
+*(No tasks — existing project structure is sufficient.)*
+
+---
+
+## Phase 2: Foundational (Blocking Prerequisites)
+
+**Purpose**: Create the core grouping composable and its types — all user stories depend on this logic.
+
+**CRITICAL**: No user story work can begin until this phase is complete.
+
+- [ ] T001 Define `SectionKey`, `EventSection`, and `DateGroup` types in `frontend/src/composables/useEventGrouping.ts`
+- [ ] T002 Implement `useEventGrouping` composable with section classification, date grouping, and sorting logic in `frontend/src/composables/useEventGrouping.ts`
+- [ ] T003 Write unit tests for `useEventGrouping` covering all four sections, empty-section omission, sort order, and Sunday edge case in `frontend/src/components/__tests__/useEventGrouping.spec.ts`
+
+**Checkpoint**: Grouping logic is fully tested and ready for consumption by UI components.
+
+---
+
+## Phase 3: User Story 1 — Temporal Section Headers (Priority: P1) MVP
+
+**Goal**: Events appear grouped under "Today", "This Week", "Later", and "Past" section headers. Empty sections are hidden.
+
+**Independent Test**: Add events with various dates to localStorage, verify they appear under correct section headers.
+
+### Tests for User Story 1
+
+> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**
+
+- [ ] T004 [P] [US1] Write unit tests for `SectionHeader.vue` rendering section label and emphasis flag in `frontend/src/components/__tests__/SectionHeader.spec.ts`
+- [ ] T005 [P] [US1] Update `EventList.spec.ts` tests to expect grouped section structure instead of flat list in `frontend/src/components/__tests__/EventList.spec.ts`
+
+### Implementation for User Story 1
+
+- [ ] T006 [P] [US1] Create `SectionHeader.vue` component with section label (`<h2>`) and `aria-label` in `frontend/src/components/SectionHeader.vue`
+- [ ] T007 [US1] Refactor `EventList.vue` template to use `useEventGrouping`, render `<section>` per temporal group with `SectionHeader`, and hide empty sections in `frontend/src/components/EventList.vue`
+- [ ] T008 [US1] Update E2E tests in `home-events.spec.ts` to verify section headers appear with correct events distributed across "Today", "This Week", "Later", "Past" in `frontend/e2e/home-events.spec.ts`
+
+**Checkpoint**: Event list shows temporal section headers. All four acceptance scenarios pass.
+
+---
+
+## Phase 4: User Story 2 — Date Subheaders Within Sections (Priority: P2)
+
+**Goal**: Within each section (except "Today"), events are further grouped by date with formatted subheaders like "Wed, 12 Mar".
+
+**Independent Test**: Add multiple events on different days within one section, verify date subheaders appear.
+
+### Tests for User Story 2
+
+> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**
+
+- [ ] T009 [P] [US2] Write unit tests for `DateSubheader.vue` rendering formatted date label in `frontend/src/components/__tests__/DateSubheader.spec.ts`
+- [ ] T010 [P] [US2] Add unit tests to `EventList.spec.ts` verifying date subheaders appear within sections and are absent in "Today" in `frontend/src/components/__tests__/EventList.spec.ts`
+
+### Implementation for User Story 2
+
+- [ ] T011 [P] [US2] Create `DateSubheader.vue` component with formatted date (`<h3>`) using `Intl.DateTimeFormat` in `frontend/src/components/DateSubheader.vue`
+- [ ] T012 [US2] Update `EventList.vue` template to render `DateSubheader` within each section's date groups, skipping subheader for "Today" section (`showSubheader` flag) in `frontend/src/components/EventList.vue`
+- [ ] T013 [US2] Add E2E test scenarios for date subheaders: multiple days within a section, no subheader in "Today" in `frontend/e2e/home-events.spec.ts`
+
+**Checkpoint**: Date subheaders render correctly within sections. "Today" section has no subheader.
+
+---
+
+## Phase 5: User Story 3 — Enhanced Event Card Time Display (Priority: P2)
+
+**Goal**: Event cards show clock time ("18:30") in Today/This Week/Later sections and relative time ("3 days ago") in Past section.
+
+**Independent Test**: Check event cards display the correct time format based on which section they appear in.
+
+### Tests for User Story 3
+
+> **NOTE: Write these tests FIRST, ensure they FAIL before implementation**
+
+- [ ] T014 [P] [US3] Add unit tests to `EventCard.spec.ts` for `timeDisplayMode` prop: `'clock'` renders formatted time, `'relative'` renders relative time in `frontend/src/components/__tests__/EventCard.spec.ts`
+
+### Implementation for User Story 3
+
+- [ ] T015 [US3] Add `timeDisplayMode` prop (`'clock' | 'relative'`) to `EventCard.vue`, render clock time via `Intl.DateTimeFormat({ hour: '2-digit', minute: '2-digit' })` or existing `formatRelativeTime()` in `frontend/src/components/EventCard.vue`
+- [ ] T016 [US3] Update `EventList.vue` to pass `timeDisplayMode="clock"` for today/thisWeek/later sections and `timeDisplayMode="relative"` for past section in `frontend/src/components/EventList.vue`
+- [ ] T017 [US3] Add E2E test scenarios verifying clock time in future sections and relative time in past section in `frontend/e2e/home-events.spec.ts`
+
+**Checkpoint**: Time display adapts to section context. All three acceptance scenarios pass.
+
+---
+
+## Phase 6: User Story 4 — Today Section Visual Emphasis (Priority: P3)
+
+**Goal**: The "Today" section header is visually more prominent (bolder, slightly larger, accent border) than other sections.
+
+**Independent Test**: Visual verification that "Today" stands out compared to other section headers.
+
+- [ ] T018 [US4] Add `.section--today` CSS class to `SectionHeader.vue` with `font-weight: 800`, `font-size: 1.1rem`, and left border accent (`#F06292`) — triggered by `emphasized` prop in `frontend/src/components/SectionHeader.vue`
+- [ ] T019 [US4] Verify `EventList.vue` passes `emphasized: true` for the "Today" section (already set via `EventSection.emphasized` from data model) in `frontend/src/components/EventList.vue`
+- [ ] T020 [US4] Add visual E2E assertion checking that the "Today" section header has the emphasis CSS class applied in `frontend/e2e/home-events.spec.ts`
+
+**Checkpoint**: "Today" section is visually distinct. Past events remain faded.
+
+---
+
+## Phase 7: Polish & Cross-Cutting Concerns
+
+**Purpose**: Final validation and regression checks.
+
+- [ ] T021 Run full unit test suite (`cd frontend && npm run test:unit`) and fix any regressions
+- [ ] T022 Run full E2E test suite and verify all existing functionality (swipe-to-delete, role badges, empty state, navigation) still works in `frontend/e2e/home-events.spec.ts`
+- [ ] T023 Verify accessibility: section headers are `<h2>`, date subheaders are `<h3>`, sections have `aria-label`, keyboard navigation works
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: Empty — no work needed
+- **Foundational (Phase 2)**: No dependencies — can start immediately
+- **US1 (Phase 3)**: Depends on Phase 2 (grouping composable)
+- **US2 (Phase 4)**: Depends on Phase 3 (needs section structure in EventList)
+- **US3 (Phase 5)**: Depends on Phase 3 (needs section context for time mode)
+- **US4 (Phase 6)**: Depends on Phase 3 (needs SectionHeader component)
+- **Polish (Phase 7)**: Depends on all user stories being complete
+
+### User Story Dependencies
+
+- **US1 (P1)**: Can start after Foundational — no dependencies on other stories
+- **US2 (P2)**: Depends on US1 (needs section structure in template to add subheaders)
+- **US3 (P2)**: Depends on US1 (needs section context to determine time mode), independent of US2
+- **US4 (P3)**: Depends on US1 (needs SectionHeader component), independent of US2/US3
+
+### Parallel Opportunities
+
+- **Phase 2**: T001 must precede T002; T003 can run after T002
+- **Phase 3**: T004 and T005 in parallel; T006 in parallel with tests; T007 after T006
+- **Phase 4**: T009 and T010 in parallel; T011 in parallel with tests; T012 after T011
+- **Phase 5**: T014 can start as soon as US1 is done; T015 after T014; T016 after T015
+- **Phase 6**: T018 can run in parallel with Phase 5 (different files)
+- **US3 and US4** can run in parallel after US1 completes
+
+---
+
+## Parallel Example: After US1 Completes
+
+```bash
+# These can run in parallel (different files, no dependencies):
+Task: T009 [US2] Write DateSubheader unit tests
+Task: T014 [US3] Write EventCard time mode unit tests
+Task: T018 [US4] Add .section--today CSS to SectionHeader.vue
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 2: Foundational (grouping composable + tests)
+2. Complete Phase 3: User Story 1 (section headers in EventList)
+3. **STOP and VALIDATE**: Test US1 independently
+4. Deploy/demo if ready — list is already grouped with headers
+
+### Incremental Delivery
+
+1. Phase 2 → Grouping logic ready
+2. Add US1 → Section headers visible → Deploy/Demo (MVP!)
+3. Add US2 → Date subheaders within sections → Deploy/Demo
+4. Add US3 → Context-aware time display → Deploy/Demo
+5. Add US4 → Visual polish for "Today" → Deploy/Demo
+6. Each story adds value without breaking previous stories

-# Feature Specification: Bookmark an Event
-
-**Feature**: `011-bookmark-event`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md
-
-> **Note on directory naming**: The migration task list labeled this directory `us-06-calendar-export`, but US-6 in userstories.md is "Bookmark an event". Calendar export is US-8. The directory was created with the correct name reflecting the actual story content.
-
-## User Scenarios & Testing
-
-### User Story 1 - Bookmark an event without RSVP (Priority: P1)
-
-A guest who has opened an event page wants to save it for later without committing to attendance. They activate a "Remember" / "Follow" action on the event page. The event token, title, and date are stored in localStorage — no server request is made. The bookmark persists across browser sessions on the same device. The guest can unfollow by activating the action again.
-
-**Why this priority**: Core bookmarking capability — without this, the entire feature has no value.
-
-**Independent Test**: Can be fully tested by visiting an event page, activating the bookmark action, closing the browser, and reopening to verify persistence. Delivers value by enabling the local event overview (US-7) to display bookmarked events.
-
-**Acceptance Scenarios**:
-
-1. **Given** a guest has opened an event page, **When** they activate the "Remember" / "Follow" action, **Then** the event token, title, and date are stored in localStorage and no server request is made.
-2. **Given** a guest has bookmarked an event, **When** they close and reopen the browser, **Then** the bookmark is still present in localStorage.
-3. **Given** a guest has bookmarked an event, **When** they activate the bookmark action again, **Then** the bookmark is removed from localStorage ("unfollow") without any server contact.
-4. **Given** a guest has bookmarked an event, **When** the event page is loaded again, **Then** the bookmark action reflects the current bookmarked state.
-
----
-
-### User Story 2 - Bookmark is independent of RSVP state (Priority: P2)
-
-A guest who has already RSVPed to an event on their device can still explicitly bookmark or un-bookmark the event. The bookmark state is tracked separately from RSVP state.
-
-**Why this priority**: Important for correctness but not the primary use case. The primary scenario is the undecided guest who wants to remember without committing.
-
-**Independent Test**: Can be tested by RSVPing to an event and then toggling the bookmark action — both states persist independently in localStorage.
-
-**Acceptance Scenarios**:
-
-1. **Given** a guest has RSVPed "attending" on this device, **When** they activate the bookmark action, **Then** the bookmark is stored independently and the RSVP state is unaffected.
-2. **Given** a guest has bookmarked an event and RSVPed, **When** they remove the bookmark, **Then** the RSVP state is unaffected.
-
----
-
-### User Story 3 - Bookmark available on expired events (Priority: P2)
-
-A guest who is viewing an event that has passed its expiry date can still bookmark it, so it remains visible in their local event overview (US-7).
-
-**Why this priority**: Edge case that ensures continuity of the local overview even for past events.
-
-**Independent Test**: Can be tested by visiting an expired event page and verifying the bookmark action is present and functional.
-
-**Acceptance Scenarios**:
-
-1. **Given** an event has passed its expiry date, **When** a guest views the event page, **Then** the bookmark action is still shown and functional.
-2. **Given** a guest bookmarks an expired event, **When** they view their local event overview (US-7), **Then** the event appears in the list marked as ended.
-
----
-
-### Edge Cases
-
-- What happens when the event title or date changes after bookmarking? Locally cached title and date may become stale if the organizer edits the event — this is an accepted trade-off. Cached values are refreshed when the guest next visits the event page.
-- How does the app handle localStorage being unavailable (e.g. private browsing in some browsers)? [NEEDS EXPANSION]
-- What happens if the guest bookmarks the same event from multiple devices? Each device maintains its own independent bookmark — no server-side sync.
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: The event page MUST display a "Remember" / "Follow" action accessible to any visitor holding the event link.
-- **FR-002**: Activating the bookmark action MUST store the event token, event title, and event date in localStorage with no server request.
-- **FR-003**: The bookmark MUST persist across browser sessions on the same device.
-- **FR-004**: A second activation of the bookmark action MUST remove the bookmark ("unfollow") with no server contact.
-- **FR-005**: The bookmark state MUST be independent of the RSVP state — both can coexist for the same event on the same device.
-- **FR-006**: The bookmark action MUST remain available on event pages where the event has expired.
-- **FR-007**: No personal data, IP address, or identifier MUST be transmitted to the server when bookmarking or un-bookmarking.
-- **FR-008**: The bookmark action MUST reflect the current state (bookmarked / not bookmarked) when the event page loads.
-
-### Key Entities
-
-- **Bookmark record** (localStorage): Stored per event token. Contains: event token, event title, event date. Indicates the guest has explicitly bookmarked this event without RSVPing. Independent of the RSVP record.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: A guest can bookmark an event and find it in their local overview (US-7) without any server contact at any point in the bookmark flow.
-- **SC-002**: Bookmarking and un-bookmarking produce no network requests (verifiable via browser DevTools).
-- **SC-003**: A bookmark persists after browser restart on the same device.
-- **SC-004**: The bookmark state is correctly reflected on the event page across multiple sessions.
-- **SC-005**: Guests with existing RSVPs on this device can independently toggle the bookmark without affecting their RSVP state.

+# Data Model: View Attendee List (011)
+
+**Date**: 2026-03-08
+
+## Entities
+
+### Rsvp (existing — no schema changes)
+
+The attendee list feature reads from the existing `rsvps` table. No new tables or columns are required.
+
+| Field | Type | Constraints | Notes |
+|-------|------|-------------|-------|
+| id | BIGSERIAL | PK, auto-increment | Chronological order proxy |
+| rsvp_token | UUID | UNIQUE, NOT NULL | Public identifier |
+| event_id | BIGINT | FK → events.id, NOT NULL | CASCADE DELETE |
+| name | VARCHAR(100) | NOT NULL | Display name shown to organizer |
+
+**Existing indexes**: `idx_rsvps_event_id` (on `event_id`), `idx_rsvps_rsvp_token` (on `rsvp_token`).
+
+### Event (existing — no schema changes)
+
+The `organizer_token` column on the `events` table is used for authorization. The endpoint verifies that the provided organizer token matches the event's stored token.
+
+| Field | Type | Notes |
+|-------|------|-------|
+| organizer_token | UUID | UNIQUE, NOT NULL — used for attendee list authorization |
+
+## Query Patterns
+
+### Get attendees by event token
+
+```sql
+SELECT r.name
+FROM rsvps r
+JOIN events e ON r.event_id = e.id
+WHERE e.event_token = :eventToken
+ORDER BY r.id ASC;
+```
+
+**Performance**: Uses existing `idx_rsvps_event_id` index. Expected result set is small (spec assumes small-to-medium events, no pagination needed).
+
+### Organizer token verification
+
+```sql
+SELECT e.organizer_token
+FROM events e
+WHERE e.event_token = :eventToken;
+```
+
+Already implemented in `EventService.getByEventToken()` — the event entity includes the organizer token. The use case compares the provided token against the stored one.
+
+## Domain Model Changes
+
+### New Outbound Port Method
+
+```java
+// RsvpRepository (existing interface)
+List<Rsvp> findByEventId(Long eventId);  // NEW
+```
+
+### New Inbound Port
+
+```java
+// GetAttendeesUseCase (new interface)
+List<String> getAttendeeNames(EventToken eventToken, OrganizerToken organizerToken);
+```
+
+Returns a list of attendee display names. Throws `EventNotFoundException` if event token is invalid. Throws `AccessDeniedException` (or similar) if organizer token does not match.
+
+## No Migration Required
+
+All required data structures already exist from changeset `003-create-rsvps-table.xml`. This feature only adds read access to existing data.

+# Implementation Plan: View Attendee List
+
+**Branch**: `011-view-attendee-list` | **Date**: 2026-03-08 | **Spec**: [spec.md](spec.md)
+**Input**: Feature specification from `/specs/011-view-attendee-list/spec.md`
+
+## Summary
+
+Add an organizer-only attendee list to the event detail view. A new `GET /events/{token}/attendees?organizerToken=<uuid>` endpoint returns attendee names when the organizer token is valid (403 otherwise). The frontend conditionally renders the list below the attendee count when the viewer is identified as the organizer via localStorage.
+
+## 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 + Testcontainers (backend integration), Vitest (frontend unit), Playwright + MSW (E2E)
+**Target Platform**: Self-hosted web application (PWA)
+**Project Type**: Web application (full-stack)
+**Performance Goals**: Attendee list loads within 2 seconds (SC-001)
+**Constraints**: Privacy by Design — attendee names only exposed to organizer; no PII logging
+**Scale/Scope**: Small-to-medium events; no pagination required (spec assumption)
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| I. Privacy by Design | ✅ PASS | Attendee names only exposed via organizer token verification. Non-organizers see count only (FR-003). No analytics/tracking added. |
+| II. Test-Driven Methodology | ✅ PASS | Plan follows Research → Spec → Test → Implement. TDD enforced. E2E tests mandatory for both user stories. |
+| III. API-First Development | ✅ PASS | New endpoint defined in OpenAPI spec first. Types generated before implementation. Response schemas include `example:` fields. |
+| IV. Simplicity & Quality | ✅ PASS | Minimal new code: one endpoint, one use case, one component section. No over-engineering. |
+| V. Dependency Discipline | ✅ PASS | No new dependencies introduced. |
+| VI. Accessibility | ✅ PASS | Semantic HTML list for attendees. WCAG AA contrast. Keyboard-navigable. |
+
+**Gate result**: ALL PASS — proceed to Phase 0.

+# Quickstart: View Attendee List (011)
+
+## Prerequisites
+
+- Java 25 (SDKMAN)
+- Node.js 20+ / npm
+- PostgreSQL running (or Docker for Testcontainers)
+
+## Development Flow
+
+### 1. Update OpenAPI spec
+
+Edit `backend/src/main/resources/openapi/api.yaml` to add the `GET /events/{token}/attendees` endpoint and response schemas (see `contracts/api.md`).
+
+### 2. Generate types
+
+```bash
+# Backend: regenerate Spring interfaces
+cd backend && ./mvnw compile
+
+# Frontend: regenerate TypeScript types
+cd frontend && npm run generate:api
+```
+
+### 3. Backend implementation (TDD)
+
+```bash
+# Write tests first
+cd backend && ./mvnw test
+
+# Run specific test class
+cd backend && ./mvnw test -Dtest=EventControllerIntegrationTest
+cd backend && ./mvnw test -Dtest=RsvpServiceTest
+```
+
+### 4. Frontend implementation (TDD)
+
+```bash
+# Unit tests
+cd frontend && npm run test:unit
+
+# E2E tests
+cd frontend && npx playwright test e2e/view-attendee-list.spec.ts
+```
+
+### 5. Verify
+
+```bash
+# Backend full verify (includes checkstyle)
+cd backend && ./mvnw verify
+
+# Frontend build check
+cd frontend && npm run build
+```

+# Research: View Attendee List (011)
+
+**Date**: 2026-03-08 | **Status**: Complete
+
+## 1. Organizer Token Verification Pattern
+
+**Decision**: Query parameter `?organizerToken=<uuid>` on the new endpoint.
+
+**Rationale**: The project uses token-based access control without persistent sessions. The organizer token is stored in localStorage on the client. Passing it as a query parameter is the simplest approach that fits the existing architecture. The `GET /events/{token}` endpoint already uses path-based token lookup; adding a query parameter for the organizer token keeps the two concerns separate.
+
+**Alternatives considered**:
+- Authorization header: More RESTful, but adds complexity without benefit — no auth framework in place, and query params are simpler for this single use case.
+- Embed attendees in existing `GET /events/{token}` response: Rejected per spec clarification — separate endpoint keeps concerns clean and avoids exposing attendee data in the public response.
+
+## 2. Endpoint Design
+
+**Decision**: `GET /events/{token}/attendees?organizerToken=<uuid>` returns `{ attendees: [{ name: string }] }`.
+
+**Rationale**:
+- Nested under `/events/{token}` — resource hierarchy is clear.
+- Returns an object with an `attendees` array (not a raw array) — allows future extension (e.g., adding metadata) without breaking the contract.
+- Each attendee object contains only `name` — minimal data exposure per Privacy by Design.
+- HTTP 403 for invalid/missing organizer token (not 401 — no authentication scheme exists).
+- HTTP 404 if the event token is invalid (consistent with existing `GET /events/{token}`).
+
+**Alternatives considered**:
+- Return `{ attendees: [...], count: N }`: Rejected — count is derivable from array length, and already available on the existing event detail endpoint. Avoids redundancy.
+- Include RSVP timestamp: Rejected — spec says chronological order but doesn't require displaying timestamps. Order is implicit in array position.
+
+## 3. Backend Implementation Approach
+
+**Decision**: New `GetAttendeesUseCase` inbound port, implemented by `RsvpService`. New `findByEventId` method on `RsvpRepository` outbound port.
+
+**Rationale**: Follows the established hexagonal architecture pattern exactly. Each use case gets its own inbound port interface. The persistence layer already has `RsvpJpaRepository` with `countByEventId`; adding `findAllByEventIdOrderByIdAsc` is a natural extension (ID order = chronological insertion order).
+
+**Alternatives considered**:
+- Add to `GetEventUseCase`: Rejected — violates single responsibility. The event detail endpoint is public; attendee retrieval is organizer-only.
+- Direct repository call in controller: Rejected — violates hexagonal architecture.
+
+## 4. Frontend Integration Approach
+
+**Decision**: New `AttendeeList.vue` component rendered conditionally in `EventDetailView.vue` when the viewer is the organizer. Fetches attendees via separate API call after event loads.
+
+**Rationale**:
+- Separate component keeps EventDetailView manageable (it's already ~300 lines).
+- Separate API call (not bundled with event fetch) — the attendee list is organizer-only; non-organizers never trigger the request.
+- Component placed below attendee count, before RSVP form — matches spec FR-004.
+- Empty state handled within the component (FR-005).
+
+**Alternatives considered**:
+- Inline in EventDetailView without separate component: Rejected — view is already complex. A dedicated component improves readability and testability.
+- Fetch attendees in the same call as event details: Not possible — separate endpoint by design.
+
+## 5. Error Handling
+
+**Decision**: Frontend silently degrades on 403 (does not render attendee list). No error toast or message shown.
+
+**Rationale**: Per FR-007, the frontend "degrades gracefully by not rendering the list." If the organizer token is invalid (e.g., localStorage cleared on another device), the user sees the same view as a regular visitor. This is intentional — no confusing error states for edge cases that self-resolve.
+
+**Alternatives considered**:
+- Show error message on 403: Rejected — would confuse users who aren't expecting organizer features.
+- Retry with different token: Not applicable — only one token per event in localStorage.
+
+## 6. Accessibility Considerations
+
+**Decision**: Attendee list rendered as semantic `<ul>` with `<li>` items. Section has a heading for screen readers. Count label uses singular/plural form.
+
+**Rationale**: Constitution VI requires WCAG AA compliance, semantic HTML, and keyboard navigation. A list of names is naturally a `<ul>`. The heading provides structure for screen reader navigation.

+# Feature Specification: View Attendee List
+
+**Feature Branch**: `011-view-attendee-list`
+**Created**: 2026-03-08
+**Status**: Draft
+**Input**: User description: "der organisator soll die Teilnehmerliste einsehen können, wenn er sich die detail view eines eigenen events anschaut"
+
+## Clarifications
+
+### Session 2026-03-08
+
+- Q: API-Design — separater Endpoint oder bestehenden erweitern? → A: Separater Endpoint `GET /events/{token}/attendees`.
+- Q: Übermittlung des Organizer-Tokens? → A: Query-Parameter `?organizerToken=<uuid>`.
+- Q: UI-Platzierung der Attendee-Liste auf der Detail-Seite? → A: Direkt unter dem bestehenden Attendee-Count (vor dem RSVP-Formular).
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - View Attendee List as Organizer (Priority: P1)
+
+As the organizer of an event, I want to see a list of all attendees (people who RSVPed) when I view my event's detail page, so that I know who is coming.
+
+When the organizer opens the event detail view for an event they created, the page displays a list of attendee names directly below the existing attendee count (before the RSVP form). This list is only visible to the organizer — regular visitors only see the attendee count (existing behavior).
+
+**Why this priority**: This is the core feature. Without it, organizers have no way to see who signed up for their event.
+
+**Independent Test**: Can be fully tested by creating an event, submitting RSVPs from other browsers/sessions, then viewing the event detail page with the organizer token. The attendee names should be listed.
+
+**Acceptance Scenarios**:
+
+1. **Given** an organizer views their event with 3 RSVPs, **When** the detail page loads, **Then** the organizer sees a list showing all 3 attendee names.
+2. **Given** an organizer views their event with 0 RSVPs, **When** the detail page loads, **Then** the organizer sees an empty state message indicating no one has RSVPed yet.
+3. **Given** a regular visitor (non-organizer) views the same event, **When** the detail page loads, **Then** only the attendee count is shown — no individual names are visible.
+
+---
+
+### User Story 2 - Attendee Count Label (Priority: P2)
+
+As the organizer, I want the attendee list to show the total count alongside the names, so I can quickly see how many people are attending at a glance.
+
+**Why this priority**: Enhances the organizer experience but the count is already visible in the existing detail view, so this is supplementary.
+
+**Independent Test**: Can be tested by verifying the attendee count displayed next to/above the list matches the number of entries in the list.
+
+**Acceptance Scenarios**:
+
+1. **Given** an organizer views their event with 5 RSVPs, **When** the attendee list is displayed, **Then** a heading or label shows "5 Attendees" (or equivalent) above the list.
+2. **Given** an organizer views their event with 1 RSVP, **When** the attendee list is displayed, **Then** the label uses singular form ("1 Attendee").
+
+---
+
+### Edge Cases
+
+- What happens when the organizer token stored locally is invalid or belongs to a different event? The system treats the viewer as a regular visitor and shows the count only — no error is displayed.
+- What happens when an attendee name contains special characters or is very long? Names are displayed safely (escaped) and truncated visually if necessary.
+- What happens if a large number of attendees (e.g. 100+) have RSVPed? The list remains scrollable and performs well without pagination (events are expected to be small-to-medium scale).
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST provide a dedicated endpoint `GET /events/{token}/attendees?organizerToken=<uuid>` for organizers to retrieve the attendee list, separate from the public event detail endpoint.
+- **FR-002**: System MUST return each attendee's display name in the attendee list response.
+- **FR-003**: System MUST NOT expose individual attendee names to non-organizer visitors — only the aggregate count is shown (existing behavior preserved).
+- **FR-004**: The attendee list MUST be displayed directly below the attendee count on the event detail view (before the RSVP form) when the viewer is identified as the organizer.
+- **FR-005**: System MUST display an empty state message when no RSVPs exist for the event.
+- **FR-006**: System MUST display the total attendee count as a label alongside the attendee list.
+- **FR-007**: System MUST reject attendee list requests with an invalid or missing organizer token by returning HTTP 403 (no attendee data exposed; frontend degrades gracefully by not rendering the list).
+
+### Key Entities
+
+- **Attendee (RSVP)**: A person who has RSVPed to an event. The organizer sees their display name in a list; visitors see only the aggregate count.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: Organizers can see the full attendee name list within 2 seconds of opening their event detail page.
+- **SC-002**: Non-organizer visitors never see individual attendee names — only the count is visible.
+- **SC-003**: The attendee list correctly reflects all RSVPs submitted for the event, with no missing or duplicate entries.
+- **SC-004**: The feature works correctly on both mobile and desktop viewports.
+
+## Assumptions
+
+- The organizer is identified by having a valid organizer token stored on the client. No additional login or authentication mechanism is introduced.
+- The attendee list is read-only — the organizer cannot remove or edit attendees from this view.
+- Attendee names are displayed in the order they RSVPed (chronological).
+- The existing event detail view layout is extended, not replaced, to accommodate the attendee list section.

+# Tasks: View Attendee List
+
+**Input**: Design documents from `/specs/011-view-attendee-list/`
+**Prerequisites**: plan.md, spec.md, research.md, data-model.md, contracts/api.md
+
+**Tests**: Included — TDD enforced per constitution principle II. E2E tests mandatory per plan.
+
+**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 all descriptions
+
+---
+
+## Phase 1: Setup (API Contract)
+
+**Purpose**: Define the API contract in OpenAPI and generate types for both backend and frontend.
+
+- [x] T001 Add `GET /events/{token}/attendees` endpoint, `GetAttendeesResponse`, and `Attendee` schemas to `backend/src/main/resources/openapi/api.yaml` per `contracts/api.md`
+- [x] T002 Regenerate backend Spring interfaces (`cd backend && ./mvnw compile`)
+- [x] T003 Regenerate frontend TypeScript types (`cd frontend && npm run generate:api`)
+
+**Checkpoint**: OpenAPI spec updated, generated types available in both backend and frontend.
+
+---
+
+## Phase 2: Foundational (Backend Domain Ports)
+
+**Purpose**: Create the inbound port and extend the outbound port that all backend implementation depends on.
+
+- [x] T004 [P] Create `GetAttendeesUseCase` inbound port interface in `backend/src/main/java/de/fete/domain/port/in/GetAttendeesUseCase.java` with method `List<String> getAttendeeNames(UUID eventToken, UUID organizerToken)`
+- [x] T005 [P] Add `List<Rsvp> findByEventId(Long eventId)` method to `backend/src/main/java/de/fete/domain/port/out/RsvpRepository.java`
+
+**Checkpoint**: Domain ports defined — service and adapter implementation can begin.
+
+---
+
+## Phase 3: User Story 1 — View Attendee List as Organizer (Priority: P1) 🎯 MVP
+
+**Goal**: Organizer sees a list of attendee names on the event detail page. Non-organizers see only the count (existing behavior).
+
+**Independent Test**: Create an event, submit RSVPs, then view the detail page with the organizer token. Attendee names should be listed.
+
+### Tests for User Story 1 ⚠️
+
+> **Write these tests FIRST — ensure they FAIL before implementation.**
+
+- [x] T006 [P] [US1] Write unit tests for `RsvpService.getAttendeeNames` (valid token, invalid token, event not found, no RSVPs) in `backend/src/test/java/de/fete/application/service/RsvpServiceTest.java`
+- [x] T007 [P] [US1] Write integration tests for `GET /events/{token}/attendees` (200 with attendees, 200 empty, 403 invalid token, 404 event not found) in `backend/src/test/java/de/fete/adapter/in/web/EventControllerIntegrationTest.java`
+- [x] T008 [P] [US1] Write unit tests for `AttendeeList.vue` (renders attendee names, empty state message, loading state) in `frontend/src/components/__tests__/AttendeeList.spec.ts`
+- [x] T009 [P] [US1] Write unit tests for organizer-conditional rendering in `EventDetailView.vue` (shows list for organizer, hides for visitor) in `frontend/src/views/__tests__/EventDetailView.spec.ts`
+- [x] T010 [P] [US1] Write E2E test: organizer sees attendee names, visitor sees count only, in `frontend/e2e/view-attendee-list.spec.ts`
+
+### Backend Implementation for User Story 1
+
+- [x] T011 [P] [US1] Add `findAllByEventIdOrderByIdAsc` query method to `backend/src/main/java/de/fete/adapter/out/persistence/RsvpJpaRepository.java`
+- [x] T012 [P] [US1] Implement `findByEventId` in `backend/src/main/java/de/fete/adapter/out/persistence/RsvpPersistenceAdapter.java`
+- [x] T013 [US1] Implement `GetAttendeesUseCase` in `backend/src/main/java/de/fete/application/service/RsvpService.java` — look up event by token, verify organizer token, return attendee names ordered by ID
+- [x] T014 [US1] Add `getAttendees` endpoint handler to `backend/src/main/java/de/fete/adapter/in/web/EventController.java` — map to `GetAttendeesUseCase`, return 200/403/404
+
+### Frontend Implementation for User Story 1
+
+- [x] T015 [US1] Create `AttendeeList.vue` component in `frontend/src/components/AttendeeList.vue` — accepts attendee names array as prop, renders semantic `<ul>/<li>` list, shows empty state message when no attendees
+- [x] T016 [US1] Integrate `AttendeeList.vue` into `frontend/src/views/EventDetailView.vue` — fetch `GET /events/{token}/attendees` with organizer token from localStorage, render below attendee count (before RSVP form), silently degrade on 403
+
+**Checkpoint**: User Story 1 fully functional. Organizer sees attendee names; visitor sees count only. All tests pass.
+
+---
+
+## Phase 4: User Story 2 — Attendee Count Label (Priority: P2)
+
+**Goal**: The attendee list section shows a count label ("5 Attendees" / "1 Attendee") alongside the names.
+
+**Independent Test**: Verify the count label above the list matches the number of entries, and uses singular/plural correctly.
+
+### Tests for User Story 2 ⚠️
+
+> **Write these tests FIRST — ensure they FAIL before implementation.**
+
+- [x] T017 [P] [US2] Write unit tests for count label in `AttendeeList.vue` (plural "5 Attendees", singular "1 Attendee", zero "0 Attendees") in `frontend/src/components/__tests__/AttendeeList.spec.ts`
+
+### Implementation for User Story 2
+
+- [x] T018 [US2] Add count heading to `AttendeeList.vue` in `frontend/src/components/AttendeeList.vue` — render `<h3>` with singular/plural label based on attendee array length
+
+**Checkpoint**: User Story 2 complete. Count label renders correctly with singular/plural form. All tests pass.
+
+---
+
+## Phase 5: Polish & Cross-Cutting Concerns
+
+**Purpose**: Verification across both stories, accessibility, edge cases.
+
+- [x] T019 Run full backend verification (`cd backend && ./mvnw verify`) — checkstyle, all tests green
+- [x] T020 Run full frontend build and tests (`cd frontend && npm run build && npm run test:unit`)
+- [x] T021 Run E2E tests (`cd frontend && npx playwright test e2e/view-attendee-list.spec.ts`)
+- [x] T022 Verify WCAG AA contrast and semantic HTML (attendee list uses `<ul>/<li>`, section has heading for screen readers)
+- [x] T023 Verify edge cases: long names truncated visually, special characters escaped, large attendee list scrollable
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies — start immediately
+- **Foundational (Phase 2)**: Depends on T002 (generated backend interfaces)
+- **User Story 1 (Phase 3)**: Depends on Phase 2 completion
+- **User Story 2 (Phase 4)**: Depends on T015 (AttendeeList component exists)
+- **Polish (Phase 5)**: Depends on Phase 3 + Phase 4 completion
+
+### User Story Dependencies
+
+- **User Story 1 (P1)**: Can start after Phase 2 — no dependencies on other stories
+- **User Story 2 (P2)**: Depends on US1's `AttendeeList.vue` component (T015) existing
+
+### Within Each User Story
+
+- Tests MUST be written and FAIL before implementation
+- Ports/models before services
+- Services before endpoints/controllers
+- Backend before frontend (API must exist for frontend integration)
+
+### Parallel Opportunities
+
+- T004 + T005 can run in parallel (different files)
+- T006 + T007 + T008 + T009 + T010 can all run in parallel (different test files)
+- T011 + T012 can run in parallel (different persistence files)
+
+---
+
+## Parallel Example: User Story 1
+
+```bash
+# Launch all tests in parallel (TDD — write first):
+Task: T006 "Unit tests for RsvpService.getAttendeeNames"
+Task: T007 "Integration tests for GET /events/{token}/attendees"
+Task: T008 "Unit tests for AttendeeList.vue"
+Task: T009 "Unit tests for EventDetailView.vue organizer rendering"
+Task: T010 "E2E test for attendee list"
+
+# Launch persistence layer in parallel:
+Task: T011 "Add findAllByEventIdOrderByIdAsc to RsvpJpaRepository"
+Task: T012 "Implement findByEventId in RsvpPersistenceAdapter"
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup (OpenAPI + type generation)
+2. Complete Phase 2: Foundational (domain ports)
+3. Complete Phase 3: User Story 1 (backend + frontend)
+4. **STOP and VALIDATE**: Test independently — organizer sees names, visitor sees count only
+5. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Setup + Foundational → API contract and ports ready
+2. Add User Story 1 → Test independently → Deploy (MVP!)
+3. Add User Story 2 → Test independently → Deploy (count label enhancement)
+4. Polish phase → Full verification, accessibility, edge cases

+# Contract: HTML Meta-Tags
+
+**Feature**: 012-link-preview | **Date**: 2026-03-09
+
+## Overview
+
+This feature does not add new REST API endpoints. The contract is the HTML meta-tag structure injected into the server-rendered `index.html`.
+
+## Meta-Tag Contract: Event Pages
+
+For requests to `/events/{eventToken}` where the event exists:
+
+```html
+<!-- Open Graph -->
+<meta property="og:title" content="{event title, max 70 chars}">
+<meta property="og:description" content="{formatted description, max 200 chars}">
+<meta property="og:url" content="{absolute canonical URL}">
+<meta property="og:type" content="website">
+<meta property="og:site_name" content="fete">
+<meta property="og:image" content="{absolute URL}/og-image.png">
+
+<!-- Twitter Card -->
+<meta name="twitter:card" content="summary">
+<meta name="twitter:title" content="{event title, max 70 chars}">
+<meta name="twitter:description" content="{formatted description, max 200 chars}">
+```
+
+### Description Format
+
+Full event data:
+```
+📅 Saturday, March 15, 2026 at 7:00 PM · 📍 Berlin — First 200 chars of description...
+```
+
+No location:
+```
+📅 Saturday, March 15, 2026 at 7:00 PM — First 200 chars of description...
+```
+
+No description:
+```
+📅 Saturday, March 15, 2026 at 7:00 PM · 📍 Berlin
+```
+
+No location, no description:
+```
+📅 Saturday, March 15, 2026 at 7:00 PM
+```
+
+### Title Truncation
+
+- Titles ≤ 70 characters: used as-is.
+- Titles > 70 characters: truncated to 67 characters + "..."
+
+### HTML Escaping
+
+All meta-tag `content` values MUST be HTML-escaped:
+- `"` → `&quot;`
+- `&` → `&amp;`
+- `<` → `&lt;`
+- `>` → `&gt;`
+
+## Meta-Tag Contract: Non-Event Pages
+
+For requests to `/`, `/create`, or any other non-event, non-API, non-static route:
+
+```html
+<!-- Open Graph -->
+<meta property="og:title" content="fete">
+<meta property="og:description" content="Privacy-focused event planning. Create and share events without accounts.">
+<meta property="og:url" content="{absolute canonical URL}">
+<meta property="og:type" content="website">
+<meta property="og:site_name" content="fete">
+<meta property="og:image" content="{absolute URL}/og-image.png">
+
+<!-- Twitter Card -->
+<meta name="twitter:card" content="summary">
+<meta name="twitter:title" content="fete">
+<meta name="twitter:description" content="Privacy-focused event planning. Create and share events without accounts.">
+```
+
+## Meta-Tag Contract: Event Not Found
+
+For requests to `/events/{eventToken}` where the event does NOT exist, fall back to generic meta-tags (same as non-event pages). The Vue SPA will handle the 404 UI client-side.
+
+## Injection Mechanism
+
+The `index.html` template contains a placeholder:
+
+```html
+<head>
+  ...
+  <!-- OG_META_TAGS -->
+  ...
+</head>
+```
+
+The server replaces `<!-- OG_META_TAGS -->` with the generated meta-tag block before sending the response.

+# Data Model: Link Preview (Open Graph Meta-Tags)
+
+**Feature**: 012-link-preview | **Date**: 2026-03-09
+
+## Overview
+
+This feature does NOT introduce new database entities. It reads existing event data and projects it into HTML meta-tags. The "model" here is the meta-tag value object used during HTML generation.
+
+## Meta-Tag Value Objects
+
+### OpenGraphMeta
+
+Represents the set of Open Graph meta-tags to inject into the HTML response.
+
+| Field | Type | Source | Rules |
+|---|---|---|---|
+| `title` | String | Event title or "fete" | Max 70 chars, truncated with "..." |
+| `description` | String | Composed from event fields or generic text | Max 200 chars |
+| `url` | String | Canonical URL from request | Absolute URL |
+| `type` | String | Always "website" | Constant |
+| `siteName` | String | Always "fete" | Constant |
+| `image` | String | Static brand image URL | Absolute URL to `/og-image.png` |
+
+### TwitterCardMeta
+
+| Field | Type | Source | Rules |
+|---|---|---|---|
+| `card` | String | Always "summary" | Constant |
+| `title` | String | Same as OG title | Max 70 chars |
+| `description` | String | Same as OG description | Max 200 chars |

+# Implementation Plan: Link Preview (Open Graph Meta-Tags)
+
+**Branch**: `012-link-preview` | **Date**: 2026-03-09 | **Spec**: `specs/012-link-preview/spec.md`
+**Input**: Feature specification from `/specs/012-link-preview/spec.md`
+
+## Summary
+
+Inject Open Graph and Twitter Card meta-tags into the server-rendered HTML so that shared event links display rich preview cards in messengers and on social media. The Spring Boot backend replaces its current static SPA fallback with a controller that dynamically injects event-specific or generic meta-tags into the cached `index.html` template before serving it.
+
+## Technical Context
+
+**Language/Version**: Java 25 (backend), TypeScript 5.9 (frontend — minimal changes)
+**Primary Dependencies**: Spring Boot 3.5.x (existing), Vue 3 (existing) — no new dependencies
+**Storage**: PostgreSQL via JPA (existing event data, read-only access)
+**Testing**: JUnit 5 + Spring MockMvc (backend), Playwright (E2E)
+**Target Platform**: Self-hosted Docker container (Linux)
+**Project Type**: Web application (SPA + REST API)
+**Performance Goals**: N/A — meta-tag injection adds negligible overhead (<1ms string replacement)
+**Constraints**: Meta-tags MUST be in initial HTML response (no client-side JS injection). No external services or CDNs.
+**Scale/Scope**: Affects all HTML page responses. No new database tables or API endpoints.
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+| Principle | Status | Notes |
+|---|---|---|
+| I. Privacy by Design | ✅ PASS | No tracking, analytics, or external services. Meta-tags contain only public event info (title, date, location). No PII exposed. `og:image` is a self-hosted static asset. |
+| II. Test-Driven Methodology | ✅ PLAN | Unit tests for meta-tag generation, integration tests for controller, E2E tests for full HTML verification. TDD enforced. |
+| III. API-First Development | ✅ N/A | No new API endpoints. This feature modifies HTML serving, not the REST API. Existing OpenAPI spec unchanged. |
+| IV. Simplicity & Quality | ✅ PASS | Simple string replacement in cached HTML template. No SSR framework, no prerendering service, no user-agent sniffing. Minimal moving parts. |
+| V. Dependency Discipline | ✅ PASS | Zero new dependencies. Uses only Spring Boot's existing capabilities. |
+| VI. Accessibility | ✅ N/A | Meta-tags are invisible to users. No UI changes. |
+
+**Gate result: PASS** — No violations. No complexity tracking needed.

+# Quickstart: Link Preview (Open Graph Meta-Tags)
+
+**Feature**: 012-link-preview | **Date**: 2026-03-09
+
+## What This Feature Does
+
+Injects Open Graph and Twitter Card meta-tags into the HTML response so that shared links display rich preview cards in messengers (WhatsApp, Telegram, Signal, etc.) and on social media (Twitter/X).
+
+## How It Works
+
+1. **All HTML page requests** go through a new `SpaController` (replaces the current `PathResourceResolver` SPA fallback).
+2. The controller reads the compiled `index.html` template once at startup and caches it.
+3. For event pages (`/events/{token}`): fetches event data, generates event-specific meta-tags, injects them into the HTML.
+4. For non-event pages: injects generic fete branding meta-tags.
+5. Static files (`/assets/*`, `/favicon.svg`, `/og-image.png`) continue to be served directly by Spring Boot's default static resource handler.
+
+## Key Files to Create/Modify
+
+### Backend (New)
+
+| File | Purpose |
+|---|---|
+| `SpaController.java` | Controller handling all non-API/non-static HTML requests, injecting meta-tags |
+| `OpenGraphService.java` | Service composing meta-tag values from event data |
+| `MetaTagRenderer.java` | Utility rendering meta-tag value objects into HTML `<meta>` strings |
+
+### Backend (Modified)
+
+| File | Change |
+|---|---|
+| `WebConfig.java` | Remove `PathResourceResolver` SPA fallback (replaced by `SpaController`) |
+| `application.properties` | Add `server.forward-headers-strategy=framework` for correct URL construction behind proxies |
+
+### Frontend (Modified)
+
+| File | Change |
+|---|---|
+| `index.html` | Add `<!-- OG_META_TAGS -->` placeholder comment in `<head>` |
+
+### Static Assets (New)
+
+| File | Purpose |
+|---|---|
+| `frontend/public/og-image.png` | Brand image for `og:image` (1200x630 PNG) |
+
+## Testing Strategy
+
+- **Unit tests**: `OpenGraphService` — verify meta-tag values for various event states (full data, no location, no description, long title, special characters).
+- **Unit tests**: `MetaTagRenderer` — verify HTML escaping, correct meta-tag format.
+- **Integration tests**: `SpaController` — verify correct HTML response with meta-tags for event URLs, generic URLs, and 404 events.
+- **E2E tests**: Fetch event page HTML without JavaScript, parse meta-tags, verify values match event data.
+
+## Local Development Notes
+
+- In dev mode (Vite dev server), meta-tags won't be injected since Vite serves its own `index.html`. This is expected — meta-tag injection only works when the backend serves the frontend.
+- To test locally: build the frontend (`npm run build`), copy `dist/` contents to `backend/src/main/resources/static/`, then run the backend.
+- Alternatively, test via the Docker build which assembles everything automatically.

+# Research: Link Preview (Open Graph Meta-Tags)
+
+**Feature**: 012-link-preview | **Date**: 2026-03-09
+
+## R1: How to Serve Dynamic Meta-Tags from a Vue SPA
+
+### Problem
+
+Vue SPA serves a single `index.html` for all routes via Spring Boot's `PathResourceResolver` fallback in `WebConfig.java`. Social media crawlers (WhatsApp, Telegram, Signal, Twitter/X) do NOT execute JavaScript — they only read the initial HTML response. The current `index.html` contains no Open Graph meta-tags.
+
+### Decision: Server-Side HTML Template Injection
+
+Intercept HTML page requests in the Spring Boot backend. Before serving `index.html`, parse the route, fetch event data if applicable, and inject `<meta>` tags into the `<head>` section.
+
+### Rationale
+
+- **No new dependencies**: Uses Spring Boot's existing resource serving + simple string manipulation.
+- **No SSR framework needed**: Avoids adding Nuxt, Vite SSR, or a prerendering service.
+- **Universal**: Works for all clients (not just crawlers), improving SEO for all visitors.
+- **Simple**: The backend already serves `index.html` for all non-API/non-static routes. We just need to modify *what* HTML is returned.
+
+### Alternatives Considered
+
+| Alternative | Rejected Because |
+|---|---|
+| **Vue SSR (Nuxt/Vite SSR)** | Massive architectural change. Overkill for injecting a few meta-tags. Violates KISS. |
+| **Prerendering service (prerender.io, rendertron)** | External dependency that may phone home. Violates Privacy by Design. Adds operational complexity. |
+| **User-agent sniffing** | Fragile — crawler UA strings change frequently. Serving different content to crawlers vs. users is considered cloaking by some search engines. |
+| **Static prerendering at build time** | Events are dynamic — created at runtime. Cannot prerender at build time. |
+| **`<noscript>` fallback** | Crawlers don't read `<noscript>` content for meta-tags. Only `<meta>` tags in `<head>` are parsed. |
+
+## R2: Implementation Strategy — Where to Inject
+
+### Decision: Custom Controller Replacing SPA Fallback
+
+Replace the current `PathResourceResolver` SPA fallback in `WebConfig.java` with a dedicated `@Controller` that:
+
+1. Reads the compiled `index.html` from `classpath:/static/index.html` once at startup (cached as a template string).
+2. For requests matching `/events/{token}`: fetches the event from the database, generates meta-tags, injects them into the HTML template.
+3. For all other non-API, non-static-file requests: injects generic fete meta-tags.
+4. Returns the modified HTML with `Content-Type: text/html`.
+
+### Rationale
+
+- The existing `PathResourceResolver` approach cannot modify the HTML content — it only resolves files.
+- A controller gives full programmatic control over the response.
+- Template caching avoids repeated file I/O.
+- Event lookup is a single DB query (already exists via `EventRepository`).
+
+### Template Injection Point
+
+The `index.html` will contain a placeholder comment `<!-- OG_META_TAGS -->` in the `<head>` section. The controller replaces this placeholder with the generated meta-tags. This is done in the Vite source `index.html` and preserved through the build.
+
+## R3: Meta-Tag Content Strategy
+
+### Decision: Structured Description Format
+
+For event pages, `og:description` follows this pattern:
+```
+📅 {formatted date} · 📍 {location} — {truncated description}
+```
+
+If location is missing:
+```
+📅 {formatted date} — {truncated description}
+```
+
+If description is missing:
+```
+📅 {formatted date} · 📍 {location}
+```
+
+Date format: `EEEE, MMMM d, yyyy 'at' h:mm a` (e.g., "Saturday, March 15, 2026 at 7:00 PM") using the event's timezone.
+
+### Title truncation
+
+`og:title` = event title, truncated to 70 characters with "..." suffix if exceeded.
+
+### Description truncation
+
+Total `og:description` max 200 characters. The event description portion is truncated to fit within this limit after the date/location prefix.
+
+## R4: Brand Image for og:image
+
+### Decision: Use Existing Favicon SVG
+
+The project already has a `favicon.svg` (tada emoji). For `og:image`, we'll create a PNG version (1200x630 recommended for OG) as a static asset.
+
+### Rationale
+
+- SVG is not universally supported as `og:image` (WhatsApp and some crawlers require raster formats).
+- A simple static PNG avoids runtime image generation complexity.
+- The brand image is the same for all pages (event-specific images are out of scope per spec).
+
+### Implementation
+
+- Add a static `og-image.png` (1200x630) to `frontend/public/` so it's included in the build output.
+- The `og:image` URL will be an absolute URL: `{baseUrl}/og-image.png`.
+- The image needs to be created manually (design task) or generated from the favicon.
+
+## R5: Absolute URL Construction
+
+### Decision: Derive from Request
+
+The `og:url` and `og:image` tags require absolute URLs. These will be constructed from the incoming HTTP request's scheme, host, and port using `ServletUriComponentsBuilder`.
+
+### Rationale
+
+- Works correctly behind reverse proxies when `X-Forwarded-*` headers are configured (Spring Boot handles this by default with `server.forward-headers-strategy=framework`).
+- No need for hardcoded base URL configuration.
+- Adapts automatically to different deployment environments.
+
+### Note
+
+Spring Boot's `server.forward-headers-strategy` should be set to `framework` in production to trust proxy headers. This is typically already handled in containerized deployments.

+# Feature Specification: Link Preview (Open Graph Meta-Tags)
+
+**Feature Branch**: `012-link-preview`
+**Created**: 2026-03-09
+**Status**: Draft
+**Input**: User description: "When people share an event link, the users messenger should show information about the site in the messenger"
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Event Link Preview in Messenger (Priority: P1)
+
+A user copies the link to a specific event page and pastes it into a messenger (WhatsApp, Telegram, Signal, iMessage, etc.). The messenger automatically fetches metadata from the link and displays a rich preview card showing the event title, a short description, and the fete branding. The recipient sees this information without having to open the link.
+
+**Why this priority**: This is the core feature. Without proper meta-tags on the event page, shared links appear as bare URLs with no context, reducing click-through rates and making events harder to discover.
+
+**Independent Test**: Can be fully tested by sharing an event link in any messenger and verifying the preview card shows the correct event title, description with date and location, and the fete app name.
+
+**Acceptance Scenarios**:
+
+1. **Given** an event exists with title, date, location, and description, **When** a user shares the event URL in a messenger, **Then** the messenger displays a preview card showing the event title, a summary of the event (including date and location), and the fete app name.
+2. **Given** an event exists with all details, **When** a social media crawler fetches the event URL, **Then** the response includes Open Graph meta-tags (`og:title`, `og:description`, `og:url`, `og:type`, `og:site_name`) with correct event-specific values.
+3. **Given** an event exists, **When** a crawler fetches the event URL, **Then** the `og:description` includes the event date, location, and a truncated version of the event description (max 200 characters).
+
+---
+
+### User Story 2 - Fallback Preview for Generic Pages (Priority: P2)
+
+When a user shares a non-event page (e.g., the homepage or event list), the messenger still shows a meaningful preview with the app name and a generic description of what fete is.
+
+**Why this priority**: Users may share the main app link rather than a specific event. A generic fallback ensures every shared link looks polished.
+
+**Independent Test**: Can be tested by sharing the homepage URL in a messenger and verifying a sensible default preview appears.
+
+**Acceptance Scenarios**:
+
+1. **Given** a user shares the app homepage URL, **When** a messenger fetches the link, **Then** the preview shows the app name "fete" as the title and a generic description (e.g., "Privacy-focused event planning. Create and share events without accounts.").
+2. **Given** a user shares the event list URL, **When** a messenger fetches the link, **Then** the preview shows default app-level metadata.
+
+---
+
+### User Story 3 - Twitter/X Card Support (Priority: P3)
+
+In addition to Open Graph tags, the system provides Twitter Card meta-tags so that links shared on Twitter/X also display rich preview cards.
+
+**Why this priority**: Twitter/X uses its own card format alongside Open Graph. Adding these tags broadens the platforms where previews work correctly.
+
+**Independent Test**: Can be tested by validating the HTML source contains `twitter:card`, `twitter:title`, and `twitter:description` meta-tags.
+
+**Acceptance Scenarios**:
+
+1. **Given** an event page, **When** a Twitter/X crawler fetches the URL, **Then** the response includes `twitter:card` (set to "summary"), `twitter:title`, and `twitter:description` meta-tags with correct values.
+
+---
+
+### Edge Cases
+
+- What happens when an event has no description? The preview shows the event title, date, and location. The description meta-tag falls back to date and location only.
+- What happens when an event has no location? The description meta-tag includes the date and whatever other details are available.
+- What happens when the event title contains special characters (quotes, ampersands, angle brackets)? Meta-tag values are properly HTML-escaped.
+- How does the system handle very long event titles or descriptions? Titles are truncated at 70 characters, descriptions at 200 characters.
+- What happens when crawlers don't execute JavaScript? Meta-tags are served in the initial HTML response from the server, not injected client-side.
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: The system MUST include Open Graph meta-tags (`og:title`, `og:description`, `og:url`, `og:type`, `og:site_name`) on every event page.
+- **FR-002**: The system MUST populate `og:title` with the event title, truncated to 70 characters if necessary.
+- **FR-003**: The system MUST populate `og:description` with a summary that includes the event date, location (if available), and a truncated event description (max 200 characters total).
+- **FR-004**: The system MUST set `og:type` to "website" for all pages.
+- **FR-005**: The system MUST set `og:site_name` to "fete".
+- **FR-006**: The system MUST include fallback Open Graph meta-tags on non-event pages (homepage, event list) with a generic app description.
+- **FR-007**: The system MUST include Twitter Card meta-tags (`twitter:card`, `twitter:title`, `twitter:description`) on every page.
+- **FR-008**: The system MUST properly HTML-escape all meta-tag values to prevent rendering issues with special characters.
+- **FR-009**: The system MUST serve meta-tags in the initial HTML response (not rely on client-side JavaScript rendering) so that crawlers can read them.
+- **FR-010**: The system MUST set `og:url` to the canonical URL of the current page.
+- **FR-011**: The system MUST include an `og:image` meta-tag on every page, pointing to a generic fete brand image (logo/icon).
+
+### Key Entities
+
+- **Event Metadata**: The subset of event information used for link previews — title, date, location, description. These are read-only projections of existing event data.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: 100% of event page links display a rich preview card (with title and description) when shared in WhatsApp, Telegram, and Signal.
+- **SC-002**: All meta-tag values are correctly populated with event-specific data — verified by automated tests against the HTML output.
+- **SC-003**: Non-event pages display a meaningful generic preview when shared in messengers.
+- **SC-004**: Meta-tags are present in the initial server response (not injected by client-side JavaScript), verifiable by fetching the page without JavaScript execution.
+
+## Clarifications
+
+### Session 2026-03-09
+
+- Q: Should a generic fete brand image be included as `og:image` fallback? → A: Yes, include a generic fete brand image as `og:image` on all pages (logo/icon).
+- Q: In which language should meta-tag texts (generic description, site name) be? → A: English for all meta-tag texts.
+
+## Assumptions
+
+- The backend can serve or pre-render HTML with event-specific meta-tags for event detail pages. Since this is a Vue SPA, server-side rendering or a dedicated server-side mechanism will be needed for crawlers that don't execute JavaScript.
+- A generic fete brand image (logo/icon) is used as `og:image` on all pages. Event-specific cover images are out of scope and can be added later.
+- The date format in `og:description` uses a human-readable English format.
+- All meta-tag texts (generic descriptions, site name, fallback content) are in English.

+
+## Phase 2: Foundational (Blocking Prerequisites)
+
+**Purpose**: Core infrastructure for HTML meta-tag injection that ALL user stories depend on
+
+**⚠️ CRITICAL**: No user story work can begin until this phase is complete
+
+- [x] T004 Write unit tests for `MetaTagRenderer` (HTML escaping, meta-tag HTML output) in `backend/src/test/java/de/fete/adapter/in/web/MetaTagRendererTest.java` — tests MUST fail (Red)

+- [x] T019 [P] [US3] Unit tests for Twitter Card meta-tag generation — verify `twitter:card` = "summary", `twitter:title`, `twitter:description` match OG values in `backend/src/test/java/de/fete/application/service/OpenGraphServiceTest.java`
+- [x] T020 [P] [US3] Integration tests for `SpaController` — event and generic routes include Twitter Card meta-tags in `backend/src/test/java/de/fete/adapter/in/web/SpaControllerTest.java`
+
+### Implementation for User Story 3
+
+- [x] T021 [US3] Extend `OpenGraphService` to include Twitter Card meta-tags (`twitter:card`, `twitter:title`, `twitter:description`) alongside OG tags in `backend/src/main/java/de/fete/application/service/OpenGraphService.java`
+- [x] T022 [US3] Extend `MetaTagRenderer` to render `<meta name="twitter:*">` tags (using `name` attribute instead of `property`) in `backend/src/main/java/de/fete/adapter/in/web/MetaTagRenderer.java`
+- [ ] T023 [US3] E2E test — fetch event page and homepage, verify Twitter Card meta-tags present alongside OG tags in `frontend/e2e/link-preview.spec.ts`

+- [x] T027 Run full frontend test suite (`cd frontend && npm run test:unit`) — 133 tests passed
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: No dependencies — can start immediately
+- **Foundational (Phase 2)**: Depends on T001 (placeholder in index.html) — BLOCKS all user stories
+- **US1 (Phase 3)**: Depends on Foundational phase completion
+- **US2 (Phase 4)**: Depends on Foundational phase completion — can run in parallel with US1
+- **US3 (Phase 5)**: Depends on US1 or US2 (extends their meta-tag output)
+- **Polish (Phase 6)**: Depends on all user stories being complete
+
+### User Story Dependencies
+
+- **User Story 1 (P1)**: Can start after Foundational (Phase 2) — no dependencies on other stories
+- **User Story 2 (P2)**: Can start after Foundational (Phase 2) — independent from US1
+- **User Story 3 (P3)**: Depends on US1 or US2 — extends existing OG meta-tag output with Twitter tags
+
+### Within Each User Story
+
+- Tests MUST be written and FAIL before implementation (TDD Red phase)
+- Service layer before controller wiring
+- Unit tests before integration tests before E2E tests
+- Story complete before moving to next priority
+
+### Parallel Opportunities
+
+- T001, T002, T003 can all run in parallel (Setup phase)
+- T004 and T006 can run in parallel (Foundational tests — different files)
+- T009, T010 can run in parallel (US1 tests — different files)
+- T014, T015 can run in parallel (US2 tests — different files)
+- T019, T020 can run in parallel (US3 tests — different files)
+- US1 and US2 can be worked on in parallel after Foundational phase
+
+---
+
+## Parallel Example: User Story 1
+
+```bash
+# Launch US1 tests in parallel (Red phase):
+Task: "Unit tests for OpenGraphService.buildEventMeta() in OpenGraphServiceTest.java"
+Task: "Integration tests for SpaController event routes in SpaControllerTest.java"
+
+# Then implement sequentially:
+Task: "Implement OpenGraphService.buildEventMeta()"
+Task: "Wire SpaController for /events/{token} routes"
+Task: "E2E test for event page meta-tags"
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup (T001–T003)
+2. Complete Phase 2: Foundational (T004–T008)
+3. Complete Phase 3: User Story 1 (T009–T013)
+4. **STOP and VALIDATE**: Share an event link in a messenger, verify preview card
+5. Deploy/demo if ready
+
+### Incremental Delivery
+
+1. Setup + Foundational → SpaController serving index.html with placeholder replacement
+2. Add US1 → Event links show rich previews → Deploy (MVP!)
+3. Add US2 → Generic pages also show previews → Deploy
+4. Add US3 → Twitter/X cards work too → Deploy
+5. Polish → Edge cases hardened → Final release
+

+
+## Notes
+
+- [P] tasks = different files, no dependencies
+- [Story] label maps task to specific user story for traceability
+- Each user story is independently completable and testable
+- TDD enforced: write tests first, verify they fail, then implement
+- Commit after each task or logical group
+- Stop at any checkpoint to validate story independently

-# Feature Specification: Local Event Overview List
-
-**Feature**: `012-local-event-overview`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md
-
-## User Scenarios & Testing
-
-### User Story 1 - View tracked events on the root page (Priority: P1)
-
-A user who has created, bookmarked, or RSVPed to events on this device opens the root page (`/`) and sees a list of all those events, each with the event title, date, and their relationship to the event (organizer / attending / not attending / bookmarked only). Each entry is a link to the event page. The list is rendered entirely from localStorage — no server request is required. If no events are tracked locally, an empty state is shown.
-
-**Why this priority**: This is the core feature — the reason the overview exists. Without this story, no other scenario is meaningful.
-
-**Independent Test**: Can be fully tested by seeding localStorage with event entries (simulating US-1/US-3/US-6 data) and loading the root page. Delivers value by allowing users to navigate back to any tracked event without the original link.
-
-**Acceptance Scenarios**:
-
-1. **Given** the user has created an event from this device (organizer token in localStorage), **When** they navigate to `/`, **Then** the event appears in the list with title, date, and relationship "organizer"
-2. **Given** the user has RSVPed "attending" to an event from this device, **When** they navigate to `/`, **Then** the event appears in the list with title, date, and relationship "attending"
-3. **Given** the user has RSVPed "not attending" to an event from this device, **When** they navigate to `/`, **Then** the event appears in the list with title, date, and relationship "not attending"
-4. **Given** the user has bookmarked an event from this device (US-6), **When** they navigate to `/`, **Then** the event appears in the list with title, date, and relationship "bookmarked only"
-5. **Given** no events are tracked in localStorage, **When** the user navigates to `/`, **Then** an empty state message is shown — not an error
-6. **Given** the list is rendered, **When** the user clicks an entry, **Then** they are navigated directly to the event page for that entry
-
----
-
-### User Story 2 - Visually distinguish past events (Priority: P2)
-
-Events whose date has passed are still shown in the list but rendered with a visual distinction (e.g. marked as "ended"), so the user can differentiate between upcoming and past events at a glance.
-
-**Why this priority**: Useful for UX clarity but the overview is still functional without this distinction. Past events in the list are still navigable.
-
-**Independent Test**: Can be tested by placing a past-dated event entry in localStorage and loading the root page. The entry should appear visually distinct from current events.
-
-**Acceptance Scenarios**:
-
-1. **Given** an event in localStorage has a date in the past, **When** the user views the overview, **Then** the entry is visually distinguished (e.g. marked "ended") compared to upcoming events
-2. **Given** an event in localStorage has a date in the future, **When** the user views the overview, **Then** the entry is rendered without any "ended" indicator
-
----
-
-### User Story 3 - Remove an entry from the local list (Priority: P2)
-
-The user can remove individual entries from the local overview. The behavior depends on the entry type: for bookmarked-only events the bookmark is removed; for RSVPed events the local record is removed (server-side RSVP unaffected); for organizer-created events the organizer token and event data are removed from localStorage, with a confirmation warning that organizer access on this device will be lost.
-
-**Why this priority**: Important for list hygiene but not required for the core navigation use case.
-
-**Independent Test**: Can be tested by placing entries of each type in localStorage and verifying removal behavior from the overview UI.
-
-**Acceptance Scenarios**:
-
-1. **Given** a bookmarked-only event is in the local list, **When** the user removes that entry, **Then** the bookmark is removed from localStorage and the entry disappears from the list
-2. **Given** an RSVPed event is in the local list, **When** the user removes that entry, **Then** the local RSVP record is removed from localStorage; the server-side RSVP is unaffected
-3. **Given** an organizer-created event is in the local list, **When** the user initiates removal, **Then** a confirmation warning is shown explaining that organizer access on this device will be revoked
-4. **Given** the organizer confirms removal, **Then** the organizer token and event metadata are removed from localStorage and the entry disappears from the list
-
----
-
-### User Story 4 - Handle a deleted event when navigating from the overview (Priority: P2)
-
-If the user clicks an entry in the local overview and the server responds that the event no longer exists (deleted per US-12 automatic cleanup or US-19 organizer deletion), the app displays an "event no longer exists" message and offers to remove the entry from the local list.
-
-**Why this priority**: Edge case that improves consistency and prevents stale entries from accumulating, but not core to the overview's primary purpose.
-
-**Independent Test**: Can be tested by navigating to an event whose token does not exist on the server. The app should display a "no longer exists" message and offer removal.
-
-**Acceptance Scenarios**:
-
-1. **Given** an entry exists in the local overview, **When** the user navigates to that event and the server returns "event not found", **Then** the app displays an "event no longer exists" message and offers to remove the entry from the local list
-2. **Given** the user confirms removal of the stale entry, **Then** the entry is removed from localStorage and the user is returned to the overview
-
----
-
-### Edge Cases
-
-- What happens if localStorage is unavailable or disabled in the browser? The overview cannot render — [NEEDS EXPANSION: define fallback message or behavior]
-- What happens if the same event appears under multiple localStorage keys (e.g. both RSVPed and organizer)? [NEEDS EXPANSION: define de-duplication or priority rule for relationship label]
-- What happens if an event's locally cached title or date is stale (organizer edited via US-5)? Stale values are displayed until the user next visits the event page — this is an accepted trade-off per the story notes.
-- What happens when the user has a very large number of tracked events? [NEEDS EXPANSION: pagination or truncation strategy]
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: The root page (`/`) MUST display the local event overview list below a project header/branding section
-- **FR-002**: The list MUST include any event for which an organizer token, RSVP record, or bookmark exists in localStorage for this device
-- **FR-003**: Each list entry MUST show at minimum: event title, event date, and the user's relationship to the event (organizer / attending / not attending / bookmarked only)
-- **FR-004**: Each list entry MUST be a link that navigates directly to the corresponding event page
-- **FR-005**: The list MUST be populated entirely from localStorage — no server request is made to render the overview
-- **FR-006**: Events whose date has passed MUST be visually distinguished (e.g. marked "ended") from upcoming events
-- **FR-007**: An individual entry MUST be removable from the list; removal behavior depends on entry type (bookmark removal, local RSVP record removal, or organizer token removal)
-- **FR-008**: Removing an organizer-created event entry MUST require a confirmation warning explaining that organizer access on this device will be revoked
-- **FR-009**: No personal data or event data MUST be transmitted to the server when viewing or interacting with the overview
-- **FR-010**: If no events are tracked locally, an empty state MUST be shown — not an error or blank screen
-- **FR-011**: When navigating from the overview to an event that the server reports as deleted, the app MUST display an "event no longer exists" message and offer to remove the stale entry from the local list
-
-### Key Entities
-
-- **LocalEventEntry**: A localStorage-stored record representing one tracked event. Contains at minimum: event token, event title, event date, and relationship type (organizer / attending / not attending / bookmarked). May also contain: organizer token (for organizer entries), RSVP choice and name (for RSVP entries).
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: A user with events tracked in localStorage can navigate to `/` and see all tracked events without any server request being made
-- **SC-002**: Each event entry links correctly to its event page
-- **SC-003**: Past events are visually distinguishable from upcoming events in the list
-- **SC-004**: An entry can be removed from the list, and the corresponding localStorage key is cleaned up correctly for each entry type
-- **SC-005**: The empty state is shown when no events are tracked in localStorage — no blank page or error state

-# Feature Specification: Add Event to Calendar
-
-**Feature**: `013-calendar-export`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md
-
-## User Scenarios & Testing
-
-### User Story 1 - Download .ics file (Priority: P1)
-
-A guest who wants to remember the event opens the event page and downloads an iCalendar file to import into their personal calendar application. The file contains all relevant event details: title, description, start date/time, location, and the public event URL. The UID in the file is derived from the event token so that re-downloading the file and re-importing it updates the existing calendar entry rather than creating a duplicate.
-
-**Why this priority**: Core calendar integration — the most common and universally supported way to add an event to a calendar across all platforms.
-
-**Independent Test**: Can be fully tested by visiting a valid event page, clicking the `.ics` download link, and verifying the downloaded file is a valid iCalendar (RFC 5545) document with the correct event fields and a stable UID.
-
-**Acceptance Scenarios**:
-
-1. **Given** a valid event page, **When** the guest clicks the `.ics` download link, **Then** a standards-compliant iCalendar file is downloaded containing the event title, description (if present), start date and time, location (if present), the public event URL, and a unique UID derived from the event token.
-2. **Given** the guest downloads the `.ics` file twice for the same event, **When** they import both files into a calendar application, **Then** the calendar application updates the existing entry rather than creating a duplicate (due to the stable UID).
-3. **Given** a guest holding only the event link (no RSVP, no login), **When** they access the `.ics` download link, **Then** the file is served without requiring any authentication or personal data.
-4. **Given** an event whose expiry date has passed, **When** the guest accesses the `.ics` download link, **Then** the file is still served (the guest can still obtain the calendar record of a past event).
-
----
-
-### User Story 2 - Subscribe via webcal:// link (Priority: P2)
-
-A guest subscribes to the event via a `webcal://` link so that their calendar application automatically picks up any changes — such as a rescheduled date or updated location — when the organizer edits the event via US-5.
-
-**Why this priority**: Adds live-update value on top of the static `.ics` download. Requires the `.ics` download (P1) to already work. Most useful in conjunction with US-5 (Edit event details).
-
-**Independent Test**: Can be tested by opening the `webcal://` URL in a calendar application and verifying it subscribes to the feed and shows the correct event details.
-
-**Acceptance Scenarios**:
-
-1. **Given** a valid event page, **When** the guest clicks the `webcal://` subscription link, **Then** their calendar application subscribes to the feed and displays the event.
-2. **Given** a subscribed `webcal://` feed and an organizer who edits the event date via US-5, **When** the calendar application syncs the feed, **Then** the calendar entry is updated to reflect the new date.
-3. **Given** a `webcal://` endpoint, **When** it is accessed, **Then** it serves identical iCalendar content as the `.ics` download, using the same event token in the URL.
-
----
-
-### User Story 3 - Cancelled event reflected in calendar (Priority: P3)
-
-When an event is cancelled (US-18), the `.ics` file and `webcal://` feed include `STATUS:CANCELLED` so that subscribed calendar applications reflect the cancellation automatically on their next sync.
-
-**Why this priority**: Quality-of-life enhancement dependent on US-18 (cancel event). Deferred until US-18 is implemented.
-
-**Independent Test**: Can be tested by cancelling an event and verifying the calendar feed includes `STATUS:CANCELLED`.
-
-**Acceptance Scenarios**:
-
-1. **Given** an event that has been cancelled (US-18), **When** a calendar application syncs the `webcal://` feed, **Then** the calendar entry is updated to show the cancelled status.
-2. **Given** an event that has been cancelled (US-18), **When** the guest downloads the `.ics` file, **Then** it includes `STATUS:CANCELLED`.
-
-> **Note**: Deferred until US-18 is implemented.
-
----
-
-### Edge Cases
-
-- What happens when the event has no description or location? The `.ics` file must omit those optional fields rather than including blank values.
-- What happens if the server has no public URL configured? The event URL included in the `.ics` file must always be the correct public event URL.
-- What happens if the event's date or timezone changes after a guest already imported the `.ics` file? The static import will be stale; the `webcal://` subscription will auto-update on next sync.
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: System MUST expose a server-side endpoint that generates and serves a standards-compliant iCalendar (RFC 5545) `.ics` file for any event identified by its event token.
-- **FR-002**: The `.ics` file MUST include: event title, description (if present), start date and time, location (if present), the public event URL, and a unique UID derived from the event token.
-- **FR-003**: The UID in the `.ics` file MUST be stable across regenerations (same event token always produces the same UID) so that calendar applications update existing entries on re-import rather than creating duplicates.
-- **FR-004**: The `.ics` file MUST be generated server-side; no external calendar or QR code service is called.
-- **FR-005**: System MUST expose a `webcal://` subscription endpoint that serves identical iCalendar content as the `.ics` download, using the same event token in the URL.
-- **FR-006**: Both the `.ics` download link and the `webcal://` subscription link MUST be accessible to any visitor holding the event link — no RSVP, login, or personal data required.
-- **FR-007**: No personal data, name, or IP address MUST be logged when either link is accessed.
-- **FR-008**: Both links MUST remain available and functional after the event's expiry date has passed.
-- **FR-009**: When an event is cancelled (US-18), the `.ics` file and `webcal://` feed MUST include `STATUS:CANCELLED`. [Deferred until US-18 is implemented]
-
-### Key Entities
-
-- **CalendarFeed**: A virtual resource derived from the Event entity. Identified by the event token. Serialized to iCalendar (RFC 5545) format on demand. Has no independent storage — always generated from current event state.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: Downloading the `.ics` file and importing it into a standard calendar application (Google Calendar, Apple Calendar, Outlook) results in the event appearing with correct title, date/time, and location.
-- **SC-002**: Re-importing the `.ics` file after an event edit updates the existing calendar entry rather than creating a duplicate.
-- **SC-003**: Subscribing via `webcal://` and triggering a calendar sync after an event edit (US-5) reflects the updated details in the calendar application.
-- **SC-004**: Both endpoints are accessible without authentication and without transmitting any personal data.
-- **SC-005**: No external service is contacted during `.ics` generation or `webcal://` feed serving.

-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md

-> **NOTE on directory name**: The migration task list specified `us-09-reminders` for this directory, but US-9 in userstories.md is "Highlight changed event details". The directory has been created as `014-highlight-changes` to match the actual story content. This is consistent with corrections made in iterations 16 (us-06-bookmark-event) and 18 (us-08-calendar-export).
-
-## User Scenarios & Testing
-
-### User Story 1 - Guest sees highlight for recently changed fields (Priority: P1)
-
-A guest opens an event page that the organizer has edited since the guest's last visit. Changed fields (e.g. new date, new location) are visually highlighted so the guest immediately notices what is different. After the page loads, the highlight is cleared for the next visit.
-
-**Why this priority**: Core value of the feature — guests must notice important updates like a rescheduled date or changed location without having to read the entire page again.
-
-**Independent Test**: Can be fully tested by creating an event, visiting it (establishing `last_seen_at`), editing it as organizer, then revisiting as guest — changed fields appear highlighted; unmodified fields do not.
-
-**Acceptance Scenarios**:
-
-1. **Given** a guest has previously visited an event page (establishing `last_seen_at` in localStorage), **When** the organizer saves an edit that changes one or more fields, **Then** on the guest's next visit those changed fields are visually highlighted with a "recently changed" indicator.
-2. **Given** an event with an edit, **When** a guest opens the event page and the `last_edited_at` timestamp is newer than the stored `last_seen_at`, **Then** only the fields changed in the most recent edit are highlighted; unmodified fields are not highlighted.
-3. **Given** a guest who has seen the latest edit, **When** they visit the event page again without any new edits having occurred, **Then** no highlights are shown.
-
----
-
-### User Story 2 - No highlight on first visit (Priority: P2)
-
-A guest opens an event page for the first time (no `last_seen_at` in localStorage). Even if the organizer has made edits since creation, no "recently changed" highlights are shown — the event is new to the guest, so labelling fields as changed would be misleading.
-
-**Why this priority**: Correctness requirement. Showing highlights on first visit would be confusing because the guest has no reference point for what "changed" means.
-
-**Independent Test**: Can be tested by clearing localStorage and opening an edited event page — no highlight indicators should appear.
-
-**Acceptance Scenarios**:
-
-1. **Given** no `last_seen_at` value in localStorage for a given event token, **When** a guest opens the event page, **Then** no field highlights are shown regardless of whether the organizer has made edits.
-2. **Given** a first visit with no `last_seen_at`, **When** the event page is rendered, **Then** `last_seen_at` is written to localStorage with the current `last_edited_at` value, so the next visit will correctly compare against it.
-
----
-
-### User Story 3 - Highlight clears after viewing (Priority: P2)
-
-After the guest views the highlighted changes, the highlight is cleared on the next visit. Subsequent visits to the same event page (without new edits) show no highlights.
-
-**Why this priority**: Without this, the highlight would become permanent noise rather than a meaningful "new change" signal.
-
-**Independent Test**: Can be tested by visiting an event page with a change (seeing highlights), then visiting again — highlights should be gone.
-
-**Acceptance Scenarios**:
-
-1. **Given** a guest views an event page with highlighted fields, **When** the page is rendered, **Then** `last_seen_at` in localStorage is updated to match the current `last_edited_at`.
-2. **Given** `last_seen_at` was updated on the previous visit, **When** the guest visits the event page again (with no new edits), **Then** no highlights are shown.
-
----
-
-### User Story 4 - Only most recent edit is tracked (Priority: P3)
-
-If the organizer makes multiple successive edits, only the fields changed in the most recent edit are highlighted. Intermediate changes between visits are not accumulated.
-
-**Why this priority**: Simplicity constraint — tracking the full change history is overengineered for this scope. Guests see what changed last, not everything that ever changed.
-
-**Independent Test**: Can be tested by making two successive edits to different fields, then visiting as a guest — only fields from the second edit are highlighted.
-
-**Acceptance Scenarios**:
-
-1. **Given** an organizer edits the event twice (first changing title, then changing location), **When** a guest visits the page after both edits, **Then** only the location is highlighted (changed in the most recent edit); title is not highlighted (changed in an earlier edit).
-2. **Given** an event with no edits since creation, **When** any guest visits the event page, **Then** no highlights are shown.
-
----
-
-### Edge Cases
-
-- What if the organizer edits the event while the guest has the page open? The highlight logic runs on page load; open-page state is stale and will be corrected on the next visit.
-- What if localStorage is unavailable (e.g. private browsing)? No `last_seen_at` can be stored, so the guest is treated as a first-time visitor and no highlights are shown. This is safe and graceful.
-- What if `last_edited_at` is null (event has never been edited)? No highlights are shown. The field-change metadata is only populated on the first actual edit.
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: System MUST record which fields changed (title, description, date/time, location) and store a `last_edited_at` timestamp server-side whenever the organizer saves an edit (US-5).
-- **FR-002**: System MUST include `last_edited_at` and the set of changed field names in the event page API response.
-- **FR-003**: Client MUST store a `last_seen_at` value per event token in localStorage, set to the event's `last_edited_at` on each page render.
-- **FR-004**: Client MUST compare the event's `last_edited_at` against the stored `last_seen_at` on page load to determine whether highlights should be shown.
-- **FR-005**: Client MUST display a "recently changed" visual indicator next to each field that appears in the server's changed-fields set, only when `last_edited_at` is newer than `last_seen_at`.
-- **FR-006**: Client MUST NOT show any highlights when no `last_seen_at` is present in localStorage for the event (first visit).
-- **FR-007**: Client MUST NOT show any highlights when `last_edited_at` is null or equal to `last_seen_at`.
-- **FR-008**: Client MUST update `last_seen_at` in localStorage after rendering the event page, regardless of whether highlights were shown.
-- **FR-009**: System MUST NOT transmit any visit data or `last_seen_at` value to the server — the read-state tracking is entirely client-side.
-- **FR-010**: System MUST track only the most recent edit's changed fields; intermediate changes between visits are not accumulated.
-
-### Key Entities
-
-- **EditMetadata** (server-side): Records `last_edited_at` timestamp and the set of changed field names for an event. Associated with the event record. Populated on first edit; overwritten on each subsequent edit.
-- **last_seen_at** (client-side, localStorage): Per-event-token timestamp. Records when the guest last viewed the event page. Used to determine whether highlights should be shown. Never transmitted to the server.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: A guest who has visited an event page before an edit correctly sees highlight indicators on the changed fields when revisiting after the edit.
-- **SC-002**: A guest who visits an event page for the first time sees no highlight indicators, even if edits have been made.
-- **SC-003**: Highlights disappear on the guest's next visit after they have viewed the highlighted changes.
-- **SC-004**: No server request beyond the normal event page load is required to determine whether highlights should be shown.
-- **SC-005**: No visit data or read-state information is transmitted to the server — privacy is fully preserved.

-As an event organizer, I want to post short update messages on the event page and manage them, so that guests are informed of announcements or notes without requiring a separate communication channel.
-
-**Why this priority**: The ability to post and display update messages is the core capability of this feature. Without it, nothing else in this story is testable.
-
-**Independent Test**: Can be tested by creating an event, posting an update message via the organizer view, and verifying the message appears on the public event page.
-
-**Acceptance Scenarios**:
-
-1. **Given** a valid organizer token is present in localStorage, **When** the organizer submits a plain-text update message, **Then** the message is stored server-side with a timestamp and appears on the public event page in reverse chronological order.
-2. **Given** multiple update messages have been posted, **When** a guest opens the event page, **Then** all messages are displayed newest-first, each with a human-readable timestamp.
-3. **Given** a valid organizer token is present in localStorage, **When** the organizer deletes a previously posted update message, **Then** the message is permanently removed and no longer appears on the public event page.
-4. **Given** no organizer token is present in localStorage, **When** a visitor views the event page, **Then** no compose or delete UI is shown and the server rejects any attempt to post or delete update messages.
-

-
-### User Story 2 - Block posting after event expiry (Priority: P2)
-
-As an event organizer, I want to be prevented from posting update messages after the event's expiry date has passed, so that the system remains consistent with the event lifecycle.
-
-**Why this priority**: Expiry enforcement is a consistency constraint on top of the core posting capability.
-
-**Independent Test**: Can be tested by attempting to post an update message via the API after an event's expiry date and verifying a rejection response is returned.
-
-**Acceptance Scenarios**:
-
-1. **Given** an event has passed its expiry date, **When** the organizer attempts to submit an update message, **Then** the server rejects the request and the message is not stored.
-
----
-
-### Edge Cases
-
-- What happens if the organizer submits an empty or whitespace-only update message?
-- What is the maximum length of an update message? [NEEDS EXPANSION]
-- How many update messages can an event accumulate? [NEEDS EXPANSION]
-- Cancelled events (US-18): posting update messages is not blocked by cancellation, only by expiry — the organizer may want to post post-cancellation communication (e.g. a rescheduling notice or explanation).
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: System MUST allow the organizer to compose and submit a plain-text update message from the organizer view when a valid organizer token is present in localStorage.
-- **FR-002**: System MUST store each submitted update message server-side, associated with the event, with a server-assigned timestamp at the time of posting.
-- **FR-003**: System MUST display all update messages for an event on the public event page in reverse chronological order (newest first), each with a human-readable timestamp.
-- **FR-004**: System MUST reject any attempt to post an update message after the event's expiry date has passed.
-- **FR-005**: System MUST allow the organizer to permanently delete any previously posted update message from the organizer view.
-- **FR-006**: System MUST immediately remove a deleted update message from the public event page upon deletion.
-- **FR-007**: System MUST reject any attempt to post or delete update messages when the organizer token is absent or invalid.
-- **FR-008**: System MUST NOT show the compose or delete UI to visitors who do not have a valid organizer token in localStorage.
-- **FR-009**: System MUST NOT log personal data or IP addresses when update messages are fetched or posted.
-
-### Key Entities
-
-- **UpdateMessage**: A plain-text message associated with an event. Key attributes: event reference, message body (plain text), created_at timestamp. Owned by the event; deleted when the event is deleted (US-12, US-19) or manually removed by the organizer.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: A posted update message appears on the public event page without requiring a page reload beyond the normal navigation.
-- **SC-002**: Deleting an update message removes it from the public event page immediately upon deletion confirmation.
-- **SC-003**: An attempt to post an update message without a valid organizer token returns a 4xx error response from the server.
-- **SC-004**: An attempt to post an update message after the event's expiry date returns a 4xx error response from the server.
-- **SC-005**: No IP addresses or personal data appear in server logs when update messages are fetched or posted.

-# Feature Specification: New-Update Indicator for Guests
-
-**Feature**: `016-guest-notifications`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md
-
-## User Scenarios & Testing
-
-### User Story 1 - Unread update indicator (Priority: P1)
-
-A guest opens the event page and sees a visual indicator (badge or highlighted section) drawing attention to update messages that were posted since their last visit. The read state is tracked entirely in localStorage — no server involvement.
-
-**Why this priority**: Core purpose of this feature. Without this, guests miss new organizer announcements unless they manually read through all messages.
-
-**Independent Test**: Can be tested by opening an event page after new update messages have been posted, verifying that a badge or visual highlight appears on the update messages section.
-
-**Acceptance Scenarios**:
-
-1. **Given** a guest has previously visited the event page and `updates_last_seen_at` is stored in localStorage, **When** they return and the event has updates newer than `updates_last_seen_at`, **Then** a visual indicator is shown drawing attention to the unread messages.
-2. **Given** the event page is rendered with unread updates shown, **When** the page finishes loading, **Then** `updates_last_seen_at` in localStorage is updated to the timestamp of the most recent update, so the indicator does not appear on the next visit.
-3. **Given** a guest opens the event page and all updates are older than the stored `updates_last_seen_at`, **When** the page loads, **Then** no "new update" indicator is shown.
-
----
-
-### User Story 2 - First visit: no indicator (Priority: P2)
-
-A guest who has never visited the event page before (no `updates_last_seen_at` in localStorage) sees the update messages without any "new" badge or indicator.
-
-**Why this priority**: A first-time visitor has not established a baseline; labeling existing updates as "new" would be misleading since they have never seen the event before.
-
-**Independent Test**: Can be tested by opening an event page on a device with no prior localStorage state for that event token, verifying that no unread indicator is shown even if update messages are present.
-
-**Acceptance Scenarios**:
-
-1. **Given** a guest opens an event page for the first time (no `updates_last_seen_at` in localStorage for this event token), **When** the page loads and update messages are present, **Then** no "new update" indicator is shown and `updates_last_seen_at` is initialized to the most recent update timestamp.
-
----
-
-### User Story 3 - No server read-tracking (Priority: P1)
-
-No server request is made to record that a guest viewed the updates. The read state is purely client-side.
-
-**Why this priority**: Fundamental privacy requirement — tracking which guests have read which updates would be a form of user surveillance, violating the project's privacy statutes.
-
-**Independent Test**: Can be tested by inspecting network traffic when a guest opens the event page, verifying that no "mark as read" or analytics request is sent.
-
-**Acceptance Scenarios**:
-
-1. **Given** a guest opens the event page with unread updates, **When** the page loads and `updates_last_seen_at` is updated in localStorage, **Then** no additional server request is made to record the read event.
-
----
-
-### Edge Cases
-
-- What happens when all update messages are deleted (US-10a) and a guest reopens the page? The stored `updates_last_seen_at` should remain in localStorage; no indicator is shown since there are no updates to compare against.
-- What happens if localStorage is unavailable (private browsing, storage quota exceeded)? The indicator is not shown (degrades gracefully); no error is displayed to the user.
-- The `updates_last_seen_at` key is separate from the `last_seen_at` key used in US-9 (field-change highlights). The two mechanisms operate independently.
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: System MUST display a visual indicator (badge or highlighted section) on the event page when the guest has unread update messages, determined by comparing the newest update's timestamp against `updates_last_seen_at` stored in localStorage.
-- **FR-002**: System MUST store the `updates_last_seen_at` timestamp in localStorage per event token after each page render, so the indicator clears on subsequent visits.
-- **FR-003**: System MUST NOT show a "new update" indicator on a guest's first visit to an event page (when no `updates_last_seen_at` exists in localStorage for that event token).
-- **FR-004**: System MUST initialize `updates_last_seen_at` in localStorage on first visit, set to the timestamp of the most recent update (or a sentinel value if no updates exist), to prevent spurious indicators on subsequent visits.
-- **FR-005**: System MUST NOT transmit any data to the server when a guest views or is marked as having read update messages — read tracking is purely client-side.
-- **FR-006**: System MUST use a localStorage key distinct from the `last_seen_at` key used in US-9 to avoid conflicts between the two read-state mechanisms.
-- **FR-007**: System MUST degrade gracefully if localStorage is unavailable: no indicator is shown, and no error is surfaced to the user.
-
-### Key Entities
-
-- **UpdateReadState** (client-side only): Stored in localStorage, keyed by event token. Contains `updates_last_seen_at` (timestamp of the most recent update at last visit). Never transmitted to the server.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: A guest who has not visited an event page since a new update was posted sees a visual indicator on their next visit, without any server request being made to track readership.
-- **SC-002**: After the event page is rendered, the same guest sees no indicator on their next visit (indicator clears after viewing).
-- **SC-003**: A first-time visitor to an event page with existing updates sees no "new" indicator.
-- **SC-004**: No network request is sent to the server when the read state transitions from unread to read.
-- **SC-005**: The read-state mechanism is independent of US-9's field-change highlight mechanism — toggling one does not affect the other.

-# Feature Specification: Generate a QR Code for an Event
-
-**Feature**: `017-qr-code`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md
-
-## User Scenarios & Testing
-
-### User Story 1 - Display and Download QR Code (Priority: P1)
-
-Any visitor who holds the event link can view a QR code on the event page that encodes the public event URL. The QR code is generated server-side — no external service is contacted — and can be downloaded as a print-ready file (SVG or high-resolution PNG). This makes it easy to print the code on posters or flyers.
-
-**Why this priority**: This is the core deliverable of US-11. Without a downloadable, server-generated QR code, the feature has no value. All other criteria are conditions of this baseline.
-
-**Independent Test**: Can be fully tested by loading any event page and verifying that a QR code is displayed, that a download link produces a valid SVG or PNG file whose content encodes the correct event URL, and that no external network request was made to generate it.
-
-**Acceptance Scenarios**:
-
-1. **Given** a valid event exists, **When** a visitor opens the event page, **Then** a QR code encoding the public event URL is displayed on the page.
-2. **Given** a QR code is displayed, **When** the visitor clicks the download link, **Then** a file (SVG or high-resolution PNG) is downloaded directly from the app's backend without client-side generation.
-3. **Given** the downloaded file, **When** it is scanned with a QR reader, **Then** it resolves to the correct public event URL.
-4. **Given** the QR code endpoint is accessed, **When** the server generates the code, **Then** no request is made to any external QR code service.
-5. **Given** a visitor who has not RSVPed or logged in, **When** they access the event page, **Then** the QR code and download link are still available — no organizer token or RSVP required.
-6. **Given** the event has expired, **When** a visitor opens the event page, **Then** the QR code and download link remain available and functional.
-7. **Given** the QR code download is requested, **When** the server handles the request, **Then** no personal data, IP address, or identifier is transmitted to any third party.
-
----
-
-### Edge Cases
-
-- What happens when the event does not exist? The server returns "event not found" — the QR code endpoint must behave consistently and not leak data.
-- How does the download link behave when the event URL is long? The QR code must be generated at sufficient error-correction level to remain scannable even for longer URLs.
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: The event page MUST display a QR code that encodes the public event URL.
-- **FR-002**: The QR code MUST be generated entirely server-side — no external QR code service or third-party API may be contacted.
-- **FR-003**: The QR code MUST be downloadable as a file suitable for printing (SVG or high-resolution PNG).
-- **FR-004**: The QR code download MUST be served from a direct backend endpoint — the actual file download MUST NOT require client-side generation.
-- **FR-005**: The QR code MUST be accessible to any visitor holding the event link; no organizer token or RSVP is required.
-- **FR-006**: No personal data, IP address, or identifier MUST be transmitted to any third party when the QR code is generated or downloaded.
-- **FR-007**: The QR code MUST remain available and downloadable after the event has expired.
-- **FR-008**: The QR code endpoint MUST return a consistent "event not found" response if the event does not exist — no partial data or error traces may be exposed.
-
-### Key Entities
-
-- **QRCode**: Virtual — no independent storage. Generated on demand from the event token and the public event URL. Not persisted.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: A visitor can view a QR code on any event page without performing any additional action (no login, no RSVP).
-- **SC-002**: The downloaded file scans correctly to the event URL in at least two independent QR reader applications.
-- **SC-003**: No outbound network request to an external service is made during QR code generation (verifiable via network inspection).
-- **SC-004**: The QR code endpoint returns a valid file for both active and expired events.
-- **SC-005**: The download link works without JavaScript (direct server endpoint).

-# Feature Specification: Automatic Data Deletion After Expiry Date
-
-**Feature**: `018-data-deletion`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md
-
-## User Scenarios & Testing
-
-### User Story 1 - Automatic cleanup of expired event data (Priority: P1)
-
-As a guest, I want all event data — including my RSVP and any other stored personal information — to be automatically and permanently deleted after the event's expiry date, so that I can trust that data I submitted is not retained on the server longer than necessary.
-
-**Why this priority**: This is a privacy guarantee, not merely a housekeeping task. The mandatory expiry date in US-1 is only meaningful if the server actually enforces deletion. Without this story, the expiry date is a lie.
-
-**Independent Test**: Can be tested by creating an event with a near-future expiry date, submitting an RSVP, waiting for expiry, and verifying that the event's public URL returns "event not found" and no data remains accessible.
-
-**Acceptance Scenarios**:
-
-1. **Given** an event whose expiry date has passed, **When** the cleanup process runs, **Then** the event record and all associated data (RSVPs, update messages, field-change metadata, header images, cancellation state) are permanently deleted from the server.
-2. **Given** an event that has been deleted by the cleanup process, **When** a guest navigates to the event's public URL, **Then** the server returns a clear "event not found" response with no partial data or error traces.
-3. **Given** a deletion event, **When** the cleanup process deletes data, **Then** no log entry records the names, RSVPs, or any personal data of the deleted event's guests — the deletion is silent from a logging perspective.
-4. **Given** the cleanup process, **When** it runs, **Then** it runs automatically without manual operator intervention (e.g. via a scheduled job or on-request lazy cleanup triggered by access attempts).
-
----
-
-### User Story 2 - Expiry date extension delays deletion (Priority: P2)
-
-As an event organizer, I want to be able to extend the expiry date of my event (via US-5) and have the deletion be deferred accordingly, so that I can keep my event data available for longer when needed.
-
-**Why this priority**: Ensures US-5 (edit expiry date) and US-12 (deletion) work together correctly — the cleanup must always use the current stored expiry date, not the original one.
-
-**Independent Test**: Can be tested by creating an event, extending its expiry date before expiry passes, and verifying that the event data is not deleted until the new expiry date.
-
-**Acceptance Scenarios**:
-
-1. **Given** an event whose expiry date was extended via US-5 before the original expiry passed, **When** the cleanup process runs after the original date but before the new date, **Then** the event data is not deleted.
-2. **Given** an event whose expiry date was extended, **When** the new expiry date passes and the cleanup process runs, **Then** the event and all associated data are deleted.
-
----
-
-### User Story 3 - Cleanup does not trigger early (Priority: P2)
-
-As a guest, I want my event data to be retained until the expiry date has fully passed, so that I can access the event page right up until expiry without unexpected data loss.
-
-**Why this priority**: Ensures correctness — data must not be deleted prematurely.
-
-**Independent Test**: Can be tested by verifying that an event with an expiry date set to tomorrow remains fully accessible today.
-
-**Acceptance Scenarios**:
-
-1. **Given** an event whose expiry date is today but has not yet passed, **When** a guest accesses the event page, **Then** the event data is still served normally.
-2. **Given** an event whose expiry date passed yesterday, **When** the cleanup process runs, **Then** the event and all associated data are deleted.
-
----
-
-### Edge Cases
-
-- What happens if the cleanup process fails mid-run (e.g. server crash)? The next run must safely re-attempt deletion without corrupting partial state.
-- What happens if multiple cleanup runs overlap? The process must be idempotent — deleting an already-deleted event must not cause errors.
-- LocalStorage entries on guests' devices are unaffected by server-side deletion — this is intentional. The app handles the "event not found" response gracefully (US-2, US-7).
-- If a stored header image file is missing on disk at deletion time (e.g. corrupted storage), the cleanup must still complete and delete the database record.
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: The server MUST run a periodic cleanup process that automatically deletes all data associated with events whose expiry date has passed.
-- **FR-002**: The cleanup MUST delete the event record along with all associated data: RSVPs, update messages (US-10a), field-change metadata (US-9), stored header images (US-16) [deferred until US-16 is implemented], and cancellation state (US-18 if applicable).
-- **FR-003**: After deletion, the event's public URL MUST return a clear "event not found" response — no partial data is ever served.
-- **FR-004**: The cleanup process MUST run automatically without manual operator intervention (e.g. a scheduled job, Spring `@Scheduled`, or on-request lazy cleanup triggered by access attempts).
-- **FR-005**: The cleanup MUST NOT log the names, RSVPs, or any personal data of deleted events — deletion is silent from a logging perspective.
-- **FR-006**: The cleanup MUST always use the current stored expiry date when determining whether an event is eligible for deletion — extending the expiry date via US-5 before expiry passes delays deletion accordingly.
-- **FR-007**: The cleanup MUST NOT be triggered early — data is retained until the expiry date has passed, not before.
-- **FR-008**: The cleanup process MUST be idempotent — re-running it against already-deleted events must not cause errors.
-
-### Key Entities
-
-- **Event (expiry_date)**: The `expiry_date` field on the Event entity determines when the event becomes eligible for deletion. It is updated by US-5 (edit event details).
-- **Cleanup Job**: A background process (not a user-facing entity) responsible for identifying and deleting expired events and all their associated data.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: An event with a passed expiry date returns "event not found" from the server within one cleanup cycle of the expiry.
-- **SC-002**: All associated data (RSVPs, update messages, metadata, images) is deleted atomically with the event record — no orphaned records remain after a successful cleanup run.
-- **SC-003**: No PII (names, RSVP choices) appears in server logs during or after the deletion process.
-- **SC-004**: Extending an event's expiry date via US-5 correctly defers deletion — verified by querying the database after the original expiry would have triggered cleanup.
-- **SC-005**: The cleanup process completes successfully even if a stored header image file is missing on disk (resilient to partial storage failures).

-**Feature**: `019-instance-limit`
-**Created**: 2026-03-06
-**Status**: Draft
-**Source**: Migrated from spec/userstories.md (US-13)
-
-## User Scenarios & Testing
-
-### User Story 1 - Enforce Configured Event Cap on Creation (Priority: P1)
-
-As a self-hoster, I want to configure a maximum number of simultaneously active events via a server environment variable, so that I can prevent storage exhaustion and limit potential abuse on my instance without modifying code.
-
-**Why this priority**: The event cap is the primary deliverable of this story — without it, there is no feature. All other scenarios are edge cases of this core enforcement behavior.
-
-**Independent Test**: Can be fully tested by configuring `MAX_ACTIVE_EVENTS=1`, creating one event, then attempting to create a second — the second creation should be rejected with a clear error.
-
-**Acceptance Scenarios**:
-
-1. **Given** the server is configured with `MAX_ACTIVE_EVENTS=3` and 3 non-expired events exist, **When** a user submits the event creation form, **Then** the server rejects the request with a clear error indicating the instance is at capacity, and the frontend surfaces this error on the creation form — not as a silent failure.
-2. **Given** the server is configured with `MAX_ACTIVE_EVENTS=3` and 2 non-expired events exist, **When** a user submits the event creation form, **Then** the request succeeds and the new event is created normally.
-3. **Given** the server is configured with `MAX_ACTIVE_EVENTS=3` and 3 non-expired events exist, but 1 is past its expiry date (awaiting cleanup), **When** a user submits the event creation form, **Then** the request succeeds — expired events do not count toward the limit.
-
----
-
-### User Story 2 - No Limit When Variable Is Unset (Priority: P2)
-
-As a self-hoster running a personal or trusted-group instance, I want no event limit applied by default, so that I do not need to configure anything to run the app normally.
-
-**Why this priority**: The default behavior (unlimited) must be safe and require no configuration. Self-hosters who do not need a cap should not have to think about this setting.
-
-**Independent Test**: Can be fully tested by starting the server without `MAX_ACTIVE_EVENTS` set and verifying that multiple events can be created without rejection.
-
-**Acceptance Scenarios**:
-
-1. **Given** the server has no `MAX_ACTIVE_EVENTS` environment variable set, **When** any number of events are created, **Then** no capacity error is returned — event creation is unlimited.
-2. **Given** the server has `MAX_ACTIVE_EVENTS` set to an empty string, **When** events are created, **Then** no capacity error is returned — an empty value is treated the same as unset.
-
----
-
-### User Story 3 - Cap Is Enforced Server-Side Only (Priority: P2)
-
-As a self-hoster, I want the event cap to be enforced exclusively on the server, so that it cannot be bypassed by a modified or malicious client.
-
-**Why this priority**: Client-side enforcement alone would be trivially bypassable. The server is the authoritative enforcement point.
-
-**Independent Test**: Can be fully tested by sending a direct HTTP POST to the event creation endpoint (bypassing the frontend entirely) when the cap is reached — the server must reject it.
-
-**Acceptance Scenarios**:
-
-1. **Given** the configured cap is reached, **When** a direct HTTP POST is made to the event creation endpoint (bypassing the frontend), **Then** the server returns an error response indicating the instance is at capacity.
-2. **Given** the configured cap is reached, **When** no personal data is included in the rejection response or logs, **Then** the server returns only the rejection status — no PII is logged.
-
----
-
-### Edge Cases
-
-- What happens when `MAX_ACTIVE_EVENTS=0`? [NEEDS EXPANSION — treat as "no limit" or "reject all"? Clarify during implementation.]
-- What happens when `MAX_ACTIVE_EVENTS` is set to a non-integer value? The server should fail fast at startup with a clear configuration error.
-- Race condition: two concurrent creation requests when the cap is at N-1. The server must handle this atomically — one request succeeds, the other is rejected.
-- Expired events that have not yet been cleaned up must not count toward the limit. The check must query only non-expired events.
-
-## Requirements
-
-### Functional Requirements
-
-- **FR-001**: The server MUST read a `MAX_ACTIVE_EVENTS` environment variable at startup to determine the event creation cap.
-- **FR-002**: If `MAX_ACTIVE_EVENTS` is set to a positive integer and the number of non-expired events equals or exceeds that value, the server MUST reject new event creation requests with a clear error response.
-- **FR-003**: The frontend MUST surface the capacity error on the event creation form — not as a silent failure or generic error.
-- **FR-004**: If `MAX_ACTIVE_EVENTS` is unset or empty, the server MUST apply no limit — event creation is unlimited.
-- **FR-005**: Only non-expired events MUST count toward the limit; expired events awaiting cleanup are excluded from the count.
-- **FR-006**: The limit MUST be enforced server-side; client-side state or input cannot bypass it.
-- **FR-007**: No personal data or PII MUST be logged when a creation request is rejected due to the cap.
-- **FR-008**: The `MAX_ACTIVE_EVENTS` environment variable MUST be documented in the README's self-hosting section (configuration table).
-
-### Key Entities
-
-- **Event (active count)**: The count of events whose `expiry_date` is in the future. This is the value checked against `MAX_ACTIVE_EVENTS` at event creation time.
-
-## Success Criteria
-
-### Measurable Outcomes
-
-- **SC-001**: When the cap is reached, a POST to the event creation endpoint returns an appropriate HTTP error status with a machine-readable error body.
-- **SC-002**: The capacity error is displayed to the user on the creation form with a message that does not expose internal state or configuration values.
-- **SC-003**: Creating events up to but not exceeding the cap succeeds without any change in behavior compared to uncapped instances.
-- **SC-004**: The `MAX_ACTIVE_EVENTS` variable appears in the README configuration table with its type, default, and description documented.
-- **SC-005**: Expired events (past `expiry_date`) are never counted toward the cap, verifiable by inspecting the query or checking behavior after expiry.
