+```
+
+**Never use bang calls (`Ash.read!`, `Ash.get!`) without error handling:**
+
+```elixir
+# Bad - will crash on authorization errors
+members = Ash.read!(Mv.Membership.Member, actor: actor)
+
+# Good - proper error handling

 # Sidebar Analysis - Current State
 
 **Erstellt:** 2025-12-16  
-**Status:** Analyse für Neuimplementierung  
+**Last Updated:** 2026-01-13  
+**Status:** ⚠️ Veraltet - Sidebar wurde bereits implementiert (2026-01-12, PR #260)  
 **Autor:** Cursor AI Assistant
 
+> **Hinweis:** Diese Dokumentation beschreibt den Zustand VOR der Sidebar-Implementierung. Die Sidebar wurde erfolgreich implementiert und ist jetzt funktionsfähig. Siehe `sidebar-requirements-v2.md` für die finale Spezifikation.
+
 ---
 
 ## Executive Summary
 
-Die aktuelle Sidebar-Implementierung verwendet **nicht existierende Custom-CSS-Variants** (`is-drawer-close:` und `is-drawer-open:`), was zu einer defekten Implementierung führt. Die Sidebar ist strukturell basierend auf DaisyUI's Drawer-Komponente, aber die responsive und state-basierte Funktionalität ist nicht funktionsfähig.

-**Kritisches Problem:** Die im Code verwendeten Variants `is-drawer-close:*` und `is-drawer-open:*` sind **nicht in Tailwind konfiguriert**, was bedeutet, dass diese Klassen beim Build ignoriert werden.
+**Status:** Diese Analyse beschreibt Probleme, die bereits behoben wurden. Die Sidebar ist jetzt vollständig implementiert und funktionsfähig.

-# Analyse der fehlschlagenden Tests
-
-## Übersicht
-
-**Gesamtanzahl fehlschlagender Tests:** 5
-- **show_test.exs:** 1 Fehler
-- **sidebar_test.exs:** 4 Fehler
-
----
-
-## Kategorisierung
-
-### Kategorie 1: Test-Assertions passen nicht zur Implementierung (4 Tests)
-
-Diese Tests erwarten bestimmte Werte/Attribute, die in der aktuellen Implementierung anders sind oder fehlen.
-
-### Kategorie 2: Datenbank-Isolation Problem (1 Test)
-
-Ein Test schlägt fehl, weil die Datenbank nicht korrekt isoliert ist.
-
----
-
-## Detaillierte Analyse
-
-### 1. `show_test.exs` - Custom Fields Sichtbarkeit
-
-**Test:** `does not display Custom Fields section when no custom fields exist` (Zeile 112)
-
-**Problem:**
-- Der Test erwartet, dass die "Custom Fields" Sektion NICHT angezeigt wird, wenn keine Custom Fields existieren
-- Die Sektion wird aber angezeigt, weil in der Datenbank noch Custom Fields von anderen Tests vorhanden sind
-
-**Ursache:**
-- Die LiveView lädt alle Custom Fields aus der Datenbank (Zeile 238-242 in `show.ex`)
-- Die Test-Datenbank wird nicht zwischen Tests geleert
-- Da `async: false` verwendet wird, sollten die Tests sequenziell laufen, aber Custom Fields bleiben in der Datenbank
-
-**Kategorie:** Datenbank-Isolation Problem
-
----
-
-### 2. `sidebar_test.exs` - Settings Link
-
-**Test:** `T3.1: renders flat menu items with icons and labels` (Zeile 174)
-
-**Problem:**
-- Test erwartet `href="#"` für Settings
-- Tatsächlicher Wert: `href="/settings"`
-
-**Ursache:**
-- Die Implementierung verwendet einen echten Link `~p"/settings"` (Zeile 100 in `sidebar.ex`)
-- Der Test erwartet einen Placeholder-Link `href="#"`
-
-**Kategorie:** Test-Assertion passt nicht zur Implementierung
-
----
-
-### 3. `sidebar_test.exs` - Drawer Overlay CSS-Klasse
-
-**Test:** `drawer overlay is present` (Zeile 747)
-
-**Problem:**
-- Test sucht nach exakt `class="drawer-overlay"`
-- Tatsächlicher Wert: `class="drawer-overlay lg:hidden focus:outline-none focus:ring-2 focus:ring-primary"`
-
-**Ursache:**
-- Der Test verwendet eine exakte String-Suche (`~s(class="drawer-overlay")`)
-- Die Implementierung hat mehrere CSS-Klassen
-
-**Kategorie:** Test-Assertion passt nicht zur Implementierung
-
----
-
-### 4. `sidebar_test.exs` - Toggle Button ARIA-Attribut
-
-**Test:** `T5.2: toggle button has correct ARIA attributes` (Zeile 324)
-
-**Problem:**
-- Test erwartet `aria-controls="main-sidebar"` am Toggle-Button
-- Das Attribut fehlt in der Implementierung (Zeile 45-65 in `sidebar.ex`)
-
-**Ursache:**
-- Das `aria-controls` Attribut wurde nicht in der Implementierung hinzugefügt
-- Der Test erwartet es für bessere Accessibility
-
-**Kategorie:** Test-Assertion passt nicht zur Implementierung (Accessibility-Feature fehlt)
-
----
-
-### 5. `sidebar_test.exs` - Contribution Settings Link
-
-**Test:** `sidebar structure is complete with all sections` (Zeile 501)
-
-**Problem:**
-- Test erwartet Link `/contribution_settings`
-- Tatsächlicher Link: `/membership_fee_settings`
-
-**Ursache:**
-- Der Test hat eine veraltete/inkorrekte Erwartung
-- Die Implementierung verwendet `/membership_fee_settings` (Zeile 96 in `sidebar.ex`)
-
-**Kategorie:** Test-Assertion passt nicht zur Implementierung (veralteter Test)
-
----
-
-## Lösungsvorschläge
-
-### Lösung 1: `show_test.exs` - Custom Fields Sichtbarkeit
-
-**Option A: Test-Datenbank bereinigen (Empfohlen)**
-- Im `setup` Block alle Custom Fields löschen, bevor der Test läuft
-- Oder: Explizit prüfen, dass keine Custom Fields existieren
-
-**Option B: Test anpassen**
-- Den Test so anpassen, dass er explizit alle Custom Fields löscht
-- Oder: Die LiveView-Logik ändern, um nur Custom Fields zu laden, die tatsächlich existieren
-
-**Empfehlung:** Option A - Im Test-Setup alle Custom Fields löschen
-
-```elixir
-setup do
-  # Clean up any existing custom fields
-  Mv.Membership.CustomField
-  |> Ash.read!()
-  |> Enum.each(&Ash.destroy!/1)
-  
-  # Create test member
-  {:ok, member} = ...
-  %{member: member}
-end
-```
-
----
-
-### Lösung 2: `sidebar_test.exs` - Settings Link
-
-**Option A: Test anpassen (Empfohlen)**
-- Test ändern, um `href="/settings"` zu erwarten statt `href="#"`
-
-**Option B: Implementierung ändern**
-- Settings-Link zu `href="#"` ändern (nicht empfohlen, da es ein echter Link sein sollte)
-
-**Empfehlung:** Option A - Test anpassen
-
-```elixir
-# Zeile 190 ändern von:
-assert html =~ ~s(href="#")
-# zu:
-assert html =~ ~s(href="/settings")
-```
-
----
-
-### Lösung 3: `sidebar_test.exs` - Drawer Overlay CSS-Klasse
-
-**Option A: Test anpassen (Empfohlen)**
-- Test ändern, um nach der Klasse in der Klasse-Liste zu suchen (mit `has_class?` Helper)
-
-**Option B: Regex verwenden**
-- Regex verwenden, um die Klasse zu finden
-
-**Empfehlung:** Option A - Test anpassen
-
-```elixir
-# Zeile 752 ändern von:
-assert html =~ ~s(class="drawer-overlay")
-# zu:
-assert has_class?(html, "drawer-overlay")
-```
-
----
-
-### Lösung 4: `sidebar_test.exs` - Toggle Button ARIA-Attribut
-
-**Option A: Implementierung anpassen (Empfohlen)**
-- `aria-controls="main-sidebar"` zum Toggle-Button hinzufügen
-
-**Option B: Test anpassen**
-- Test entfernen oder als optional markieren (nicht empfohlen für Accessibility)
-
-**Empfehlung:** Option A - Implementierung anpassen
-
-```elixir
-# In sidebar.ex Zeile 45-52, aria-controls hinzufügen:
-<button
-  type="button"
-  id="sidebar-toggle"
-  class="hidden lg:flex ml-auto btn btn-ghost btn-sm btn-square"
-  aria-label={gettext("Toggle sidebar")}
-  aria-controls="main-sidebar"
-  aria-expanded="true"
-  onclick="toggleSidebar()"
->
-```
-
----
-
-### Lösung 5: `sidebar_test.exs` - Contribution Settings Link
-
-**Option A: Test anpassen (Empfohlen)**
-- Test ändern, um `/membership_fee_settings` statt `/contribution_settings` zu erwarten
-
-**Option B: Link hinzufügen**
-- Einen neuen Link `/contribution_settings` hinzufügen (nicht empfohlen, da redundant)
-
-**Empfehlung:** Option A - Test anpassen
-
-```elixir
-# Zeile 519 ändern von:
-"/contribution_settings",
-# zu:
-# Entfernen oder durch "/membership_fee_settings" ersetzen
-# (da "/membership_fee_settings" bereits in Zeile 518 vorhanden ist)
-```
-
----
-
-## Zusammenfassung der empfohlenen Änderungen
-
-1. **show_test.exs:** Custom Fields im Setup löschen
-2. **sidebar_test.exs (T3.1):** Settings-Link Assertion anpassen
-3. **sidebar_test.exs (drawer overlay):** CSS-Klasse-Suche mit Helper-Funktion
-4. **sidebar_test.exs (T5.2):** `aria-controls` Attribut zur Implementierung hinzufügen
-5. **sidebar_test.exs (edge cases):** Falschen Link aus erwarteter Liste entfernen
-
----
-
-## Priorisierung
-
-1. **Hoch:** Lösung 1 (show_test.exs) - Datenbank-Isolation ist wichtig
-2. **Mittel:** Lösung 4 (ARIA-Attribut) - Accessibility-Verbesserung
-3. **Niedrig:** Lösungen 2, 3, 5 - Einfache Test-Anpassungen

 # Sidebar Neuimplementierung - Schritt-für-Schritt Anleitung
 
 **Erstellt:** 2025-12-16  
-**Status:** Bereit zur Umsetzung  
+**Last Updated:** 2026-01-13  
+**Status:** ⚠️ Veraltet - Sidebar wurde bereits implementiert (2026-01-12, PR #260)  
 **Strategie:** Sequenzielle Tasks mit frischem Kontext pro Task
 
+> **Hinweis:** Diese Implementierungs-Anleitung wurde durch die tatsächliche Implementierung obsolet. Die Sidebar wurde erfolgreich implementiert. Siehe `sidebar-requirements-v2.md` für die finale Spezifikation.
+

-## Entfernte Dokumentationsdateien
+## Code Adjustments (Priority: Low)
 
-### 1. `docs/test-status-membership-fee-ui.md`
-**Grund:** Veraltete temporäre Analyse-Dokumentation
-- Enthält nur historische Test-Status-Informationen (Datum: 2025-01-XX)
-- Status "Tests Written - Implementation Complete" ist nicht mehr relevant
-- Alle Tests sind bereits implementiert und laufen
-- Informationen sind bereits in `development-progress-log.md` dokumentiert
-- **Entfernt:** 2026-01-13
+### 1. Domain Public API Documentation Incomplete
 
-### 2. `docs/test-failures-analysis.md`
-**Grund:** Veraltete temporäre Analyse-Dokumentation
-- Analysiert 5 fehlschlagende Tests, die bereits behoben wurden
-- Enthält Lösungsvorschläge für bereits gelöste Probleme
-- Informationen sind nur historisch relevant
-- Keine aktuelle Relevanz für die Codebasis
-- **Entfernt:** 2026-01-13
+**Problem:** The `@moduledoc` in domain modules does not list all public functions.
 
-## Als veraltet markierte Dokumentationsdateien
+**Affected Files:**
+- `lib/membership/membership.ex` - Missing functions in Public API:
+  - `list_required_custom_fields/0`
+  - `update_member_field_visibility/2`
+  - `update_single_member_field_visibility/3`
+- `lib/accounts/accounts.ex` - Very short Public API documentation, could be more detailed
+- `lib/membership_fees/membership_fees.ex` - Public API is complete, but could more clearly document that LiveViews use direct Ash calls
 
-### 3. `docs/sidebar-analysis-current-state.md`
-**Grund:** Veraltete Analyse-Dokumentation
-- Beschreibt den Zustand VOR der Sidebar-Implementierung
-- Sidebar wurde bereits implementiert (2026-01-12, PR #260)
-- Wurde durch `sidebar-requirements-v2.md` ersetzt
-- **Status:** Als veraltet markiert, aber behalten für historische Referenz
+**Priority:** Low (Documentation, no functionality affected)
 
-### 4. `docs/umsetzung-sidebar.md`
-**Grund:** Veraltete Implementierungs-Anleitung
-- Schritt-für-Schritt-Anleitung für Sidebar-Implementierung
-- Sidebar wurde bereits implementiert (2026-01-12, PR #260)
-- Wurde durch `sidebar-requirements-v2.md` ersetzt
-- **Status:** Als veraltet markiert, aber behalten für historische Referenz
+**Recommendation:** Update Public API sections in all domain modules to list all public functions.

+### 2. Outdated Comments in MemberLive.Form
 
-## Code-Anpassungen (Priorität: Low)
+**Problem:** `@moduledoc` in `lib/mv_web/live/member_live/form.ex` still mentions "Payment Data: Mockup section (not editable)", but Membership Fees are now fully implemented.
 
-### Keine kritischen Code-Anpassungen erforderlich

-Die Dokumentations-Synchronisation hat ergeben, dass der Code aktuell ist und mit der aktualisierten Dokumentation übereinstimmt. Alle identifizierten Unstimmigkeiten waren in der Dokumentation, nicht im Code.
+**Priority:** Low (Documentation, no functionality affected)
 
----
+**Recommendation:** Update `@moduledoc` to reflect the current status.
 
-## Veraltete Code-Patterns
+### 3. Mv.Accounts Domain Public API Missing Completely
 
-### Keine veralteten Patterns identifiziert
+**Problem:** The `@moduledoc` in `lib/accounts/accounts.ex` does not mention any Public API functions, although several are defined.
 
-Alle Code-Patterns entsprechen den aktuellen Best Practices und sind in `CODE_GUIDELINES.md` dokumentiert.

+  - `list_users/0`
+  - `update_user/2`
+  - `destroy_user/1`
+  - `create_register_with_rauthy/1`
+  - `read_sign_in_with_rauthy/1`
 
----
+**Priority:** Low (Documentation, no functionality affected)
 
-## Fehlende Implementierungen
+**Recommendation:** Add Public API section to `@moduledoc`, similar to other domain modules.
 
-### Keine fehlenden Implementierungen identifiziert
+### 4. Mv.Authorization Domain Public API Missing get_role/1
 
-Alle in der Dokumentation beschriebenen Features sind implementiert.
+**Problem:** The `@moduledoc` in `lib/mv/authorization/authorization.ex` does not list `get_role/1` in the Public API, although it is defined.
 
----
+**Affected File:**
+- `lib/mv/authorization/authorization.ex` - Missing function in Public API:
+  - `get_role/1` (is defined, but not mentioned in Public API)
 
-## Inconsistente Namensgebung
+**Priority:** Low (Documentation, no functionality affected)
 
-### Keine Inkonsistenzen identifiziert
+**Recommendation:** Add `get_role/1` to the Public API list.
 
-Die Terminologie ist konsistent zwischen Code und Dokumentation:
-- `CustomField` / `CustomFieldValue` (nicht mehr "Property" / "PropertyType")
-- `MembershipFeeType` / `MembershipFeeCycle` (korrekt verwendet)
-- Domains: `Accounts`, `Membership`, `MembershipFees`, `Authorization` (alle korrekt)
+### 5. Remove Deprecated Implementations
 
----
+**Problem:** `lib/mv_web/live/custom_field_value_live/show.ex` `MvWeb.ContributionTypeLive.Index` and `MvWeb.ContributionPeriodLive.Show` are deprecated, they should be removed.

+
+### 7. Mv.Accounts.Token @moduledoc Too Short
+
+**Problem:** The `@moduledoc` in `lib/accounts/token.ex` is very short and not informative.
+
+**Affected File:**
+- `lib/accounts/token.ex` - Currently only: "AshAuthentication specific ressource"
+
+**Priority:** Low (Documentation, no functionality affected)
+
+**Recommendation:** Expand @moduledoc to explain that this is an AshAuthentication Token Resource and is used for session management.
+
+### 8. PageController Missing @moduledoc
+
+**Problem:** The `@moduledoc` in `lib/mv_web/controllers/page_controller.ex` is completely missing.
+
+**Affected File:**
+- `lib/mv_web/controllers/page_controller.ex` - No @moduledoc present
+
+**Priority:** Low (Documentation, no functionality affected)
+
+**Recommendation:** Add @moduledoc to explain that this controller renders the homepage.
+
+**Note:** Other controller modules (Router, Endpoint, Telemetry) also do not have @moduledoc, but this is common and acceptable for standard Phoenix modules.

-# Sidebar Analysis - Current State
-
-**Erstellt:** 2025-12-16  
-**Last Updated:** 2026-01-13  
-**Status:** ⚠️ Veraltet - Sidebar wurde bereits implementiert (2026-01-12, PR #260)  
-**Autor:** Cursor AI Assistant
-
-> **Hinweis:** Diese Dokumentation beschreibt den Zustand VOR der Sidebar-Implementierung. Die Sidebar wurde erfolgreich implementiert und ist jetzt funktionsfähig. Siehe `sidebar-requirements-v2.md` für die finale Spezifikation.
-
----
-
-## Executive Summary
-
-~~Die aktuelle Sidebar-Implementierung verwendet **nicht existierende Custom-CSS-Variants** (`is-drawer-close:` und `is-drawer-open:`), was zu einer defekten Implementierung führt. Die Sidebar ist strukturell basierend auf DaisyUI's Drawer-Komponente, aber die responsive und state-basierte Funktionalität ist nicht funktionsfähig.~~
-
-**Status:** Diese Analyse beschreibt Probleme, die bereits behoben wurden. Die Sidebar ist jetzt vollständig implementiert und funktionsfähig.

-## 1. Dateien-Übersicht
-
-### 1.1 Hauptdateien
-
-| Datei | Zweck | Zeilen | Status |
-|-------|-------|--------|--------|
-| `lib/mv_web/components/layouts/sidebar.ex` | Sidebar-Komponente (Elixir) | 198 | ⚠️ Verwendet nicht existierende Variants |
-| `lib/mv_web/components/layouts/navbar.ex` | Navbar mit Sidebar-Toggle | 48 | ✅ Funktional |
-| `lib/mv_web/components/layouts.ex` | Layout-Wrapper mit Drawer | 121 | ✅ Funktional |
-| `assets/js/app.js` | JavaScript für Sidebar-Interaktivität | 272 | ✅ Umfangreiche Accessibility-Logik |
-| `assets/css/app.css` | CSS-Konfiguration | 103 | ⚠️ Keine Drawer-Variants definiert |
-| `assets/tailwind.config.js` | Tailwind-Konfiguration | 75 | ⚠️ Keine Drawer-Variants definiert |

-### 1.2 Verwandte Dateien
-
-- `lib/mv_web/components/layouts/root.html.heex` - Root-Layout (minimal, keine Sidebar-Logik)
-- `priv/static/images/logo.svg` - Logo (wird vermutlich für Sidebar benötigt)
-
----
-
-## 2. Aktuelle Struktur
-
-### 2.1 HTML-Struktur (DaisyUI Drawer Pattern)
-
-```html
-<!-- In layouts.ex -->
-<div class="drawer">
-  <input id="main-drawer" type="checkbox" class="drawer-toggle" />
-  
-  <div class="drawer-content">
-    <!-- Navbar mit Toggle-Button -->
-    <navbar with sidebar-toggle button />
-    
-    <!-- Hauptinhalt -->
-    <main>...</main>
-  </div>
-  
-  <!-- Sidebar -->
-  <div class="drawer-side">
-    <button class="drawer-overlay" onclick="close drawer"></button>
-    <nav id="main-sidebar">
-      <!-- Navigation Items -->
-    </nav>
-  </div>
-</div>
-```
-
-**Bewertung:** ✅ Korrekte DaisyUI Drawer-Struktur
-
-### 2.2 Sidebar-Komponente (`sidebar.ex`)
-
-**Struktur:**
-```elixir
-defmodule MvWeb.Layouts.Sidebar do
-  attr :current_user, :map
-  attr :club_name, :string
-  
-  def sidebar(assigns) do
-    # Rendert Sidebar mit Navigation, Locale-Selector, Theme-Toggle, User-Menu
-  end
-end
-```
-
-**Hauptelemente:**
-1. **Drawer Overlay** - Button zum Schließen (Mobile)
-2. **Navigation Container** (`<nav id="main-sidebar">`)
-3. **Menü-Items** - Members, Users, Contributions (nested), Settings
-4. **Footer-Bereich** - Locale-Selector, Theme-Toggle, User-Menu
-
----
-
-## 3. Custom CSS Variants - KRITISCHES PROBLEM
-
-### 3.1 Verwendete Variants im Code
-
-Die Sidebar verwendet folgende Custom-Variants **extensiv**:
-
-```elixir
-# Beispiele aus sidebar.ex
-"is-drawer-close:overflow-visible"
-"is-drawer-close:w-14 is-drawer-open:w-64"
-"is-drawer-close:hidden"
-"is-drawer-close:tooltip is-drawer-close:tooltip-right"
-"is-drawer-close:w-auto"
-"is-drawer-close:justify-center"
-"is-drawer-close:dropdown-end"
-```
-
-**Gefundene Verwendungen:**
-- `is-drawer-close:` - 13 Instanzen in sidebar.ex
-- `is-drawer-open:` - 1 Instanz in sidebar.ex
-
-### 3.2 Definition der Variants
-
-**❌ NICHT GEFUNDEN in:**
-- `assets/css/app.css` - Enthält nur `phx-*-loading` Variants
-- `assets/tailwind.config.js` - Enthält nur `phx-*-loading` Variants
-
-**Fazit:** Diese Variants existieren **nicht** und werden beim Tailwind-Build **ignoriert**!
-
-### 3.3 Vorhandene Variants
-
-Nur folgende Custom-Variants sind tatsächlich definiert:
-
-```css
-/* In app.css (Tailwind CSS 4.x Syntax) */
-@custom-variant phx-click-loading (.phx-click-loading&, .phx-click-loading &);
-@custom-variant phx-submit-loading (.phx-submit-loading&, .phx-submit-loading &);
-@custom-variant phx-change-loading (.phx-change-loading&, .phx-change-loading &);
-```
-
-```javascript
-/* In tailwind.config.js (Tailwind 3.x Kompatibilität) */
-plugin(({addVariant}) => addVariant("phx-click-loading", [...])),
-plugin(({addVariant}) => addVariant("phx-submit-loading", [...])),
-plugin(({addVariant}) => addVariant("phx-change-loading", [...])),
-```
-

-
-## 4. JavaScript-Implementierung
-
-### 4.1 Übersicht
-
-Die JavaScript-Implementierung ist **sehr umfangreich** und fokussiert auf Accessibility:
-
-**Datei:** `assets/js/app.js` (Zeilen 106-270)
-
-**Hauptfunktionalitäten:**
-1. ✅ Tabindex-Management für fokussierbare Elemente
-2. ✅ ARIA-Attribut-Management (`aria-expanded`)
-3. ✅ Keyboard-Navigation (Enter, Space, Escape)
-4. ✅ Focus-Management beim Öffnen/Schließen
-5. ✅ Dropdown-Integration
-
-### 4.2 Wichtige JavaScript-Funktionen
-
-#### 4.2.1 Tabindex-Management
-
-```javascript
-const updateSidebarTabIndex = (isOpen) => {
-  const allFocusableElements = sidebar.querySelectorAll(
-    'a[href], button, select, input:not([type="hidden"]), [tabindex]'
-  )
-  
-  allFocusableElements.forEach(el => {
-    if (isOpen) {
-      // Make focusable when open
-      el.removeAttribute('tabindex')
-    } else {
-      // Remove from tab order when closed
-      el.setAttribute('tabindex', '-1')
-    }
-  })
-}
-```
-
-**Zweck:** Verhindert, dass Nutzer mit Tab zu unsichtbaren Sidebar-Elementen springen können.
-
-#### 4.2.2 ARIA-Expanded Management
-
-```javascript
-const updateAriaExpanded = () => {
-  const isOpen = drawerToggle.checked
-  sidebarToggle.setAttribute("aria-expanded", isOpen.toString())
-}
-```
-
-**Zweck:** Informiert Screen-Reader über den Sidebar-Status.
-
-#### 4.2.3 Focus-Management
-
-```javascript
-const getFirstFocusableElement = () => {
-  // Priority: navigation link > other links > other focusable
-  const firstNavLink = sidebar.querySelector('a[href][role="menuitem"]')
-  // ... fallback logic
-}
-
-// On open: focus first element
-// On close: focus toggle button
-```
-
-**Zweck:** Logische Fokus-Reihenfolge für Keyboard-Navigation.
-
-#### 4.2.4 Keyboard-Shortcuts
-
-```javascript
-// ESC to close
-document.addEventListener("keydown", (e) => {
-  if (e.key === "Escape" && drawerToggle.checked) {
-    drawerToggle.checked = false
-    sidebarToggle.focus()
-  }
-})
-
-// Enter/Space on toggle button
-sidebarToggle.addEventListener("keydown", (e) => {
-  if (e.key === "Enter" || e.key === " ") {
-    // Toggle drawer and manage focus
-  }
-})
-```
-
-### 4.3 LiveView Hooks
-
-**Definierte Hooks:**
-```javascript
-Hooks.CopyToClipboard = { ... }  // Clipboard-Funktionalität
-Hooks.ComboBox = { ... }         // Dropdown-Prävention bei Enter
-```
-
-**Sidebar-spezifisch:** Keine Hooks, nur native DOM-Events.
-

-
-## 5. DaisyUI Dependencies
-
-### 5.1 Verwendete DaisyUI-Komponenten
-
-| Komponente | Verwendung | Klassen |
-|------------|-----------|---------|
-| **Drawer** | Basis-Layout | `drawer`, `drawer-toggle`, `drawer-side`, `drawer-content`, `drawer-overlay` |
-| **Menu** | Navigation | `menu`, `menu-title`, `w-64` |
-| **Button** | Toggle, User-Menu | `btn`, `btn-ghost`, `btn-square`, `btn-circle` |
-| **Avatar** | User-Menu | `avatar`, `avatar-placeholder` |
-| **Dropdown** | User-Menu | `dropdown`, `dropdown-top`, `dropdown-end`, `dropdown-content` |
-| **Tooltip** | Icon-Tooltips | `tooltip`, `tooltip-right` (via `data-tip`) |
-| **Select** | Locale-Selector | `select`, `select-sm` |
-| **Toggle** | Theme-Switch | `toggle`, `theme-controller` |
-
-### 5.2 Standard Tailwind-Klassen
-
-**Layout:**
-- `flex`, `flex-col`, `items-start`, `justify-center`
-- `gap-2`, `gap-4`, `p-4`, `mt-auto`, `w-full`, `w-64`, `min-h-full`
-
-**Sizing:**
-- `size-4`, `size-5`, `w-12`, `w-52`
-
-**Colors:**
-- `bg-base-100`, `bg-base-200`, `text-neutral-content`
-
-**Typography:**
-- `text-lg`, `text-sm`, `font-bold`
-
-**Accessibility:**
-- `sr-only`, `focus:outline-none`, `focus:ring-2`, `focus:ring-primary`
-
----
-
-## 6. Toggle-Button (Navbar)
-
-### 6.1 Implementierung
-
-**Datei:** `lib/mv_web/components/layouts/navbar.ex`
-
-```elixir
-<button
-  type="button"
-  onclick="document.getElementById('main-drawer').checked = !document.getElementById('main-drawer').checked"
-  aria-label={gettext("Toggle navigation menu")}
-  aria-expanded="false"
-  aria-controls="main-sidebar"
-  id="sidebar-toggle"
-  class="mr-2 btn btn-square btn-ghost"
->
-  <svg><!-- Layout-Panel-Left Icon --></svg>
-</button>
-```
-
-**Funktionalität:**
-- ✅ Togglet Drawer-Checkbox
-- ✅ ARIA-Labels vorhanden
-- ✅ Keyboard-accessible
-- ⚠️ `aria-expanded` wird durch JavaScript aktualisiert
-
-**Icon:** Custom SVG (Layout-Panel-Left mit Chevron-Right)
-
----
-
-## 7. Responsive Verhalten
-
-### 7.1 Aktuelles Konzept (nicht funktional)
-
-**Versuchte Implementierung:**
-- **Desktop (collapsed):** Sidebar mit 14px Breite (`is-drawer-close:w-14`)
-- **Desktop (expanded):** Sidebar mit 64px Breite (`is-drawer-open:w-64`)
-- **Mobile:** Overlay-Drawer (DaisyUI Standard)
-
-### 7.2 Problem
-
-Da die `is-drawer-*` Variants nicht existieren, gibt es **kein responsives Verhalten**:
-- Die Sidebar hat immer eine feste Breite von `w-64`
-- Die conditional hiding (`:hidden`, etc.) funktioniert nicht
-- Tooltips werden nicht conditional angezeigt
-
----
-
-## 8. Accessibility-Features
-
-### 8.1 Implementierte Features
-
-| Feature | Status | Implementierung |
-|---------|--------|-----------------|
-| **ARIA Labels** | ✅ | Alle interaktiven Elemente haben Labels |
-| **ARIA Roles** | ✅ | `menubar`, `menuitem`, `menu`, `button` |
-| **ARIA Expanded** | ✅ | Wird durch JS dynamisch gesetzt |
-| **ARIA Controls** | ✅ | Toggle → Sidebar verknüpft |
-| **Keyboard Navigation** | ✅ | Enter, Space, Escape, Tab |
-| **Focus Management** | ✅ | Logische Focus-Reihenfolge |
-| **Tabindex Management** | ✅ | Verhindert Focus auf hidden Elements |
-| **Screen Reader Only** | ✅ | `.sr-only` für visuelle Labels |
-| **Focus Indicators** | ✅ | `focus:ring-2 focus:ring-primary` |
-| **Skip Links** | ❌ | Nicht vorhanden |
-
-### 8.2 Accessibility-Score
-
-**Geschätzt:** 90/100 (WCAG 2.1 Level AA konform)
-
-**Verbesserungspotenzial:**
-- Skip-Link zur Hauptnavigation hinzufügen
-- High-Contrast-Mode testen
-
----
-
-## 9. Menü-Struktur
-
-### 9.1 Navigation Items
-
-```
-📋 Main Menu
-├── 👥 Members (/members)
-├── 👤 Users (/users)
-├── 💰 Contributions (collapsed submenu)
-│   ├── Plans (/contribution_types)
-│   └── Settings (/contribution_settings)
-└── ⚙️ Settings (/settings)
-
-🔽 Footer Area (logged in only)
-├── 🌐 Locale Selector (DE/EN)
-├── 🌓 Theme Toggle (Light/Dark)
-└── 👤 User Menu (Dropdown)
-    ├── Profile (/users/:id)
-    └── Logout (/sign-out)
-```
-
-### 9.2 Conditional Rendering
-
-**Nicht eingeloggt:**
-- Sidebar ist leer (nur Struktur)
-- Keine Menü-Items
-
-**Eingeloggt:**
-- Vollständige Navigation
-- Footer-Bereich mit User-Menu
-
-### 9.3 Nested Menu (Contributions)
-
-**Problem:** Das Contributions-Submenu ist **immer versteckt** im collapsed State:
-
-```elixir
-<li class="is-drawer-close:hidden" role="none">
-  <h2 class="flex items-center gap-2 menu-title">
-    <.icon name="hero-currency-dollar" />
-    {gettext("Contributions")}
-  </h2>
-  <ul role="menu">
-    <li class="is-drawer-close:hidden">...</li>
-    <li class="is-drawer-close:hidden">...</li>
-  </ul>
-</li>
-```
-
-Da `:hidden` nicht funktioniert, wird das Submenu immer angezeigt.
-
----
-
-## 10. Theme-Funktionalität
-
-### 10.1 Theme-Toggle
-
-```elixir
-<input
-  type="checkbox"
-  value="dark"
-  class="toggle theme-controller"
-  aria-label={gettext("Toggle dark mode")}
-/>
-```
-
-**Funktionalität:**
-- ✅ DaisyUI `theme-controller` - automatische Theme-Umschaltung
-- ✅ Persistence durch `localStorage` (siehe root.html.heex Script)
-- ✅ Icon-Wechsel (Sun ↔ Moon)
-
-### 10.2 Definierte Themes
-
-**Datei:** `assets/css/app.css`
-
-1. **Light Theme** (default)
-   - Base: `oklch(98% 0 0)`
-   - Primary: `oklch(70% 0.213 47.604)` (Orange/Phoenix-inspiriert)
-
-2. **Dark Theme**
-   - Base: `oklch(30.33% 0.016 252.42)`
-   - Primary: `oklch(58% 0.233 277.117)` (Purple/Elixir-inspiriert)
-
----
-
-## 11. Locale-Funktionalität
-
-### 11.1 Locale-Selector
-
-```elixir
-<form method="post" action="/set_locale">
-  <select
-    id="locale-select-sidebar"
-    name="locale"
-    onchange="this.form.submit()"
-    class="select select-sm w-full is-drawer-close:w-auto"
-  >
-    <option value="de">Deutsch</option>
-    <option value="en">English</option>
-  </select>
-</form>
-```
-
-**Funktionalität:**
-- ✅ POST zu `/set_locale` Endpoint
-- ✅ CSRF-Token included
-- ✅ Auto-Submit on change
-- ✅ Accessible Label (`.sr-only`)
-
----

-## 19. Zusammenfassung
-
-### 19.1 Was funktioniert
-
-✅ **Sehr gute Grundlage:**
-- DaisyUI Drawer-Pattern korrekt implementiert
-- Exzellente Accessibility (ARIA, Keyboard, Focus)
-- Saubere Modulstruktur
-- Internationalisierung
-- Theme-Switching
-- JavaScript-Logik ist robust
-
-### 19.2 Was nicht funktioniert
-
-❌ **Kritische Defekte:**
-- CSS-Variants existieren nicht → keine responsive Funktionalität
-- Kein Logo
-- Kein Toggle-Icon-Swap
-- Submenu-Handling defekt
-
-### 19.3 Nächste Schritte
-
-1. **CSS-Variants entfernen** (alle `is-drawer-*` Klassen)
-2. **Standard DaisyUI-Pattern verwenden** (ohne Custom-Variants)
-3. **Logo hinzufügen** (persistent, size-8)
-4. **Simplify:** Mobile = Overlay, Desktop = Persistent (keine collapsed State)
-5. **Tests schreiben** (Component + Accessibility)

-# Sidebar Requirements Specification v2
-
-**Erstellt:** 2025-12-16  
-**Version:** 2.0  
-**Last Updated:** 2026-01-13  
-**Status:** ✅ Implementiert (2026-01-12, PR #260)  
-**Basierend auf:** `sidebar-analysis-current-state.md`, `daisyui-drawer-pattern.md`
-
----
-
-## Executive Summary
-
-Diese Spezifikation definiert die Anforderungen für eine **standardkonforme Sidebar-Implementierung** basierend auf **DaisyUI Drawer Pattern** ohne Custom CSS Variants. Die Sidebar unterstützt Desktop (expanded/collapsed States) und Mobile (Overlay Drawer).
-
-**Kernprinzipien:**
-- ✅ **100% DaisyUI Standard** - keine Custom Variants
-- ✅ **Ein Layout** - keine Duplikate für Mobile/Desktop
-- ✅ **State via data-attribute** - CSS reagiert auf `[data-sidebar-expanded]`
-- ✅ **localStorage Persistence** - State bleibt über Seitenreloads erhalten
-- ✅ **WCAG 2.1 Level AA** - vollständig accessible

-
-## 1. Funktionale Anforderungen
-
-### 1.1 Logo
-
-| Eigenschaft | Wert | Begründung |
-|-------------|------|------------|
-| **Größe** | `size-8` (32px × 32px) | Konsistent, gut lesbar |
-| **Sichtbarkeit** | Immer sichtbar | Branding, Orientierung |
-| **States** | Gleich in expanded & collapsed | Keine unterschiedlichen Logo-Elemente |
-| **Position** | Links im Header | Standard-Pattern |
-| **Pfad** | `/images/mila.svg` | Projektspezifisch |
-
-**Verhalten:**
-- Expanded: Logo + Club-Name
-- Collapsed: Logo zentriert (horizontal & vertikal)
-
-### 1.2 Toggle-Button
-
-| Eigenschaft | Wert | Begründung |
-|-------------|------|------------|
-| **Sichtbarkeit** | Nur Desktop (≥ lg) | Mobile nutzt Hamburger in Header |
-| **Position** | Rechts im Sidebar-Header | Schnell erreichbar |
-| **Icon (expanded)** | `hero-chevron-left` | Zeigt Collapse-Richtung |
-| **Icon (collapsed)** | `hero-chevron-right` | Zeigt Expand-Richtung |
-| **Größe** | `btn-sm btn-square` | Kompakt, icon-only |
-| **Variante** | `btn-ghost` | Dezent, nicht dominant |
-
-**Icon-Swap Strategie:**
-- Zwei separate `<.icon>` Elemente
-- CSS-Klassen: `.sidebar-expanded-icon` und `.sidebar-collapsed-icon`
-- CSS zeigt/versteckt basierend auf `[data-sidebar-expanded]`
-
-**ARIA:**
-- `aria-label="Toggle sidebar"`
-- `aria-expanded="true|false"` (via JavaScript)
-- `aria-controls="main-sidebar"`
-
-### 1.3 Menü-Items (Flat)
-
-**Expanded State:**
-- Icon (links) + Text-Label (rechts)
-- Standard DaisyUI menu styling
-- Gap: `gap-3` zwischen Icon und Text
-
-**Collapsed State:**
-- Nur Icon (zentriert)
-- Tooltip erscheint rechts (`tooltip-right`)
-- Tooltip-Text aus `data-tip` Attribut
-
-**Hover-Effekt:**
-- Einheitlich für expanded UND collapsed
-- Standard DaisyUI: `hover:bg-base-300`
-- Keine Custom-Styles
-
-**Liste der Menü-Items:**
-1. **Members** - `hero-users` - `/members`
-2. **Users** - `hero-user-circle` - `/users`
-3. **Custom Fields** - `hero-rectangle-group` - `/custom_fields`
-4. **Settings** - `hero-cog-6-tooth` - `#` (Placeholder)
-
-### 1.4 Nested Menu "Beiträge" (Contributions)
-
-**Problem:** Standard Menu-Item Pattern funktioniert nicht für verschachtelte Menüs.
-
-**Lösung:** Zwei unterschiedliche Darstellungen je nach State.
-
-#### Expanded State:
-```html
-<details class="expanded-menu-group">
-  <summary>
-    Icon + "Beiträge"
-  </summary>
-  <ul>
-    <li>Beitragsarten</li>
-    <li>Einstellungen</li>
-  </ul>
-</details>
-```
-
-**Eigenschaften:**
-- Native `<details>/<summary>` für auf/zuklappbar
-- Submenu eingerückt (`ml-4`)
-- Chevron-Icon rotiert automatisch (Browser-Standard)
-
-#### Collapsed State:
-```html
-<div class="collapsed-menu-group dropdown dropdown-right">
-  <button>Icon</button>
-  <ul class="dropdown-content">
-    <li class="menu-title">Beiträge</li>
-    <li>Beitragsarten</li>
-    <li>Einstellungen</li>
-  </ul>
-</div>
-```
-
-**Eigenschaften:**
-- DaisyUI `dropdown` mit `dropdown-right`
-- Flyout erscheint RECHTS vom Icon
-- Menu-Title zeigt "Beiträge"
-- Tooltip auf Button (collapsed)
-
-**Wichtig:**
-- Nur EIN Hover-Effekt (nicht doppelt)
-- CSS-Klassen `.expanded-menu-group` und `.collapsed-menu-group`
-- CSS zeigt/versteckt basierend auf `[data-sidebar-expanded]`
-
-**Submenu-Items:**
-1. **Beitragsarten** - `/contribution_types`
-2. **Einstellungen** - `/contribution_settings`
-
-### 1.5 Footer
-
-**Position:**
-- IMMER am unteren Ende der Sidebar
-- Flexbox: Navigation mit `flex-1`, Footer mit `mt-auto`
-
-**Komponenten:**
-
-#### 1.5.1 Language Selector
-- **Sichtbarkeit:** Nur expanded (`.expanded-only`)
-- **Typ:** `<select>` mit Form (POST zu `/locale`)
-- **Variante:** `select select-sm w-full`
-- **Optionen:** Deutsch (de), English (en)
-- **Funktion:** Auto-submit on change
-
-#### 1.5.2 Theme Toggle
-- **Sichtbarkeit:** Immer (expanded & collapsed)
-- **Layout:** Horizontal: Sun Icon + Toggle + Moon Icon
-- **Variante:** `toggle toggle-sm theme-controller`
-- **Funktion:** DaisyUI automatische Theme-Umschaltung
-- **Collapsed:** Zentriert horizontal
-
-#### 1.5.3 User Menu
-- **Typ:** DaisyUI `dropdown dropdown-top dropdown-end`
-- **Avatar:** Rund, erste Buchstabe der Email, zentriert
-- **Größe:** `w-8 h-8` (collapsed), `w-10 h-10` (expanded)
-- **Email:** Nur expanded sichtbar, `truncate`
-- **Dropdown-Items:**
-  1. Profile (`/users/:id`)
-  2. Logout (`/sign-out`)
-
-**Footer-Layout:**
-```
-┌─────────────────────────┐
-│ [Language Selector]     │ ← Nur expanded
-│ ☀️ [Toggle] 🌙          │ ← Immer
-│ [Avatar] [Email ▼]      │ ← Avatar immer, Email nur expanded
-└─────────────────────────┘
-```
-
-### 1.6 State Persistence
-
-**localStorage Key:** `sidebar-expanded`
-
-**Werte:**
-- `"true"` - Sidebar ist expanded (default)
-- `"false"` - Sidebar ist collapsed
-
-**data-attribute auf Root:**
-```html
-<div data-sidebar-expanded="true">
-```
-
-**Verhalten:**
-1. Beim Mount: Restore aus localStorage
-2. Beim Toggle: Update localStorage + data-attribute
-3. CSS reagiert auf data-attribute änderung
-
-### 1.7 Responsive Verhalten
-
-**Mobile (< lg / < 1024px):**
-- Standard DaisyUI Drawer Overlay
-- Hamburger-Icon in Mobile Header (außerhalb Sidebar)
-- Overlay verdunkelt Hintergrund
-- Click auf Overlay schließt Drawer
-- Sidebar: volle Breite `w-64` (16rem)
-- Toggle-Button in Sidebar: NICHT sichtbar
-
-**Desktop (≥ lg / ≥ 1024px):**
-- Fixed Sidebar (persistent)
-- `lg:drawer-open` forciert Drawer als sichtbar
-- Expanded: `w-64` (16rem)
-- Collapsed: `w-16` (4rem)
-- Smooth width transition: `300ms ease-in-out`
-- Toggle-Button in Sidebar: sichtbar
-- Mobile Header: NICHT sichtbar (`lg:hidden`)

-## 4. CSS-Strategie
-
-### 4.1 Prinzipien
-
-✅ **Erlaubt:**
-- Tailwind `@apply` Direktiven
-- Standard DaisyUI Komponenten-Klassen
-- CSS attribute selectors (`[data-*]`)
-- Tailwind responsive modifiers (`lg:`, `md:`)
-- Standard pseudo-classes (`:hover`, `:focus`)
-
-❌ **NICHT erlaubt:**
-- Custom CSS Variants (`@custom-variant`)
-- Custom Tailwind Plugin Variants
-- Complex CSS Selectors (mehr als 3 Ebenen tief)
-- `!important` (außer in extremen Edge-Cases)
-
-### 4.2 State Management via Data-Attribute
-
-**Selector Pattern:**
-```css
-[data-sidebar-expanded="false"] .sidebar .element {
-  /* Collapsed State Styles */
-}
-```
-
-**Beispiel-Implementierung in `app.css`:**
-
-```css
-/* ============================================
-   Sidebar Base Styles
-   ============================================ */
-
-.sidebar {
-  @apply flex flex-col bg-base-200 min-h-screen;
-  @apply transition-[width] duration-300 ease-in-out;
-  width: 16rem; /* w-64 - Expanded */
-}
-
-/* Collapsed State */
-[data-sidebar-expanded="false"] .sidebar {
-  width: 4rem; /* w-16 - Collapsed */
-}
-
-/* ============================================
-   Text Labels - Fade Out in Collapsed
-   ============================================ */
-
-.menu-label {
-  @apply transition-all duration-200 whitespace-nowrap;
-  @apply opacity-100;
-}
-
-[data-sidebar-expanded="false"] .sidebar .menu-label {
-  @apply opacity-0 w-0 overflow-hidden pointer-events-none;
-}
-
-/* ============================================
-   Toggle Button Icon Swap
-   ============================================ */
-
-.sidebar-expanded-icon {
-  @apply block;
-}
-
-.sidebar-collapsed-icon {
-  @apply hidden;
-}
-
-[data-sidebar-expanded="false"] .sidebar .sidebar-expanded-icon {
-  @apply hidden;
-}
-
-[data-sidebar-expanded="false"] .sidebar .sidebar-collapsed-icon {
-  @apply block;
-}
-
-/* ============================================
-   Nested Menu - Show/Hide Based on State
-   ============================================ */
-
-.expanded-menu-group {
-  @apply block;
-}
-
-.collapsed-menu-group {
-  @apply hidden;
-}
-
-[data-sidebar-expanded="false"] .sidebar .expanded-menu-group {
-  @apply hidden;
-}
-
-[data-sidebar-expanded="false"] .sidebar .collapsed-menu-group {
-  @apply block;
-}
-
-/* ============================================
-   Elements Only Visible in Expanded State
-   ============================================ */
-
-.expanded-only {
-  @apply block transition-opacity duration-200;
-}
-
-[data-sidebar-expanded="false"] .sidebar .expanded-only {
-  @apply hidden;
-}
-
-/* ============================================
-   Tooltips - Only Show in Collapsed State
-   ============================================ */
-
-.sidebar .tooltip::before,
-.sidebar .tooltip::after {
-  @apply opacity-0 pointer-events-none;
-}
-
-[data-sidebar-expanded="false"] .sidebar .tooltip:hover::before,
-[data-sidebar-expanded="false"] .sidebar .tooltip:hover::after {
-  @apply opacity-100;
-}
-
-/* ============================================
-   Menu Item Alignment - Center in Collapsed
-   ============================================ */
-
-[data-sidebar-expanded="false"] .sidebar .menu > li > a,
-[data-sidebar-expanded="false"] .sidebar .menu > li > button {
-  @apply justify-center px-0;
-}
-```

-**Mobile (< lg):**
-- Standard DaisyUI Drawer (checkbox-basiert)
-- Keine custom State-Management
-- Sidebar immer `w-64` wenn geöffnet
-
-**Desktop (≥ lg):**
-- `lg:drawer-open` für Persistence
-- Custom State-Management via data-attribute
-- Width-Transition: `w-64` ↔ `w-16`
-
-**Keine Konflikte:**
-- `lg:drawer-open` wird NICHT durch `data-sidebar-expanded` beeinflusst
-- Collapsed State nur auf Desktop relevant
-
----
-
-## 5. State-Management-Strategie
-
-### 5.1 JavaScript Hook: `SidebarState`
-
-**Datei:** `assets/js/app.js`
-
-**Verantwortlichkeiten:**
-1. **Mount:** Restore State aus localStorage
-2. **Toggle:** Wechsle State, update localStorage + data-attribute
-3. **ARIA:** Update `aria-expanded` auf Toggle-Button
-4. **Global Function:** Expose `window.toggleSidebar()`
-
-**Implementierung:**
-
-```javascript
-Hooks.SidebarState = {
-  mounted() {
-    // Restore state from localStorage
-    const expanded = localStorage.getItem('sidebar-expanded') !== 'false';
-    this.setSidebarState(expanded);
-    
-    // Expose toggle function globally
-    window.toggleSidebar = () => {
-      const current = this.el.dataset.sidebarExpanded === 'true';
-      this.setSidebarState(!current);
-    };
-  },
-  
-  setSidebarState(expanded) {
-    // Update data-attribute (CSS reacts to this)
-    this.el.dataset.sidebarExpanded = expanded;
-    
-    // Persist to localStorage
-    localStorage.setItem('sidebar-expanded', expanded);
-    
-    // Update ARIA for accessibility
-    const toggleBtn = document.getElementById('sidebar-toggle');
-    if (toggleBtn) {
-      toggleBtn.setAttribute('aria-expanded', expanded);
-    }
-  },
-  
-  destroyed() {
-    // Cleanup
-    delete window.toggleSidebar;
-  }
-};
-```
-
-### 5.2 localStorage Schema
-
-**Key:** `sidebar-expanded`
-
-**Values:**
-- `"true"` (string) - Expanded
-- `"false"` (string) - Collapsed
-
-**Default:** `"true"` (wenn Key nicht existiert)
-
-**Warum String?**
-- localStorage speichert nur Strings
-- Vermeidet Parsing-Fehler
-- Einfache Vergleiche
-
-### 5.3 CSS Reactions
-
-**Automatisch via Attribute Selector:**
-
-```html
-<!-- Expanded -->
-<div data-sidebar-expanded="true">
-  <aside class="sidebar"> <!-- width: 16rem -->
-    <span class="menu-label">Members</span> <!-- visible -->
-  </aside>
-</div>
-
-<!-- Collapsed -->
-<div data-sidebar-expanded="false">
-  <aside class="sidebar"> <!-- width: 4rem -->
-    <span class="menu-label">Members</span> <!-- hidden -->
-  </aside>
-</div>
-```
-
-**Vorteile:**
-- Keine JavaScript DOM-Manipulation
-- CSS Transitions funktionieren automatisch
-- Performance: GPU-accelerated
-- Wartbar: State ist zentral
-
-### 5.4 Event Flow
-
-```
-User clicks Toggle-Button
-         │
-         ▼
-onclick="toggleSidebar()"
-         │
-         ▼
-JavaScript Hook: setSidebarState(!current)
-         │
-         ├─▶ Update data-attribute
-         ├─▶ Save to localStorage
-         └─▶ Update aria-expanded
-         │
-         ▼
-CSS Reactions
-         │
-         ├─▶ Sidebar width transition
-         ├─▶ Labels fade out/in
-         ├─▶ Icons show/hide
-         └─▶ Tooltips enable/disable
-         │
-         ▼
-User sees smooth animation
-```
-
-**Keine Komplexität:**
-- ❌ Kein tabindex management
-- ❌ Kein focus management
-- ❌ Keine event listener cleanup
-- ❌ Keine checkbox manipulation

-## 7. Accessibility (WCAG 2.1 Level AA)
-
-### 7.1 Semantic HTML
-
-| Element | Semantik | ARIA |
-|---------|----------|------|
-| `<nav>` | Hauptnavigation | `aria-label="Main navigation"` |
-| `<ul role="menubar">` | Menu Container | `role="menubar"` |
-| `<li role="none">` | List Item (deaktiviert) | `role="none"` |
-| `<a role="menuitem">` | Menu Item | `role="menuitem"` |
-| `<button aria-haspopup>` | Dropdown Trigger | `aria-haspopup="menu"` |
-| `<details>` | Expandable Section | Native HTML (kein ARIA nötig) |
-
-### 7.2 ARIA-Attribute
-
-**Toggle-Button:**
-```html
-<button
-  aria-label="Toggle sidebar"
-  aria-expanded="true"
-  aria-controls="main-sidebar"
->
-```
-
-**User Menu:**
-```html
-<button
-  aria-label="User menu"
-  aria-haspopup="menu"
-  aria-expanded="false"
->
-```
-
-**Icons (dekorativ):**
-```html
-<.icon name="hero-users" aria-hidden="true" />
-```
-
-**Tooltips:**
-```html
-<a data-tip="Members" class="tooltip tooltip-right">
-  <!-- Tooltip ist visuell, nicht für Screen Reader -->
-</a>
-```
-
-### 7.3 Keyboard Navigation
-
-**Fokussierbare Elemente:**
-- Toggle-Button (Space/Enter)
-- Menu-Items (Enter)
-- User-Menu-Button (Space/Enter, Arrows für Navigation)
-- Dropdowns (Tab, Arrows, Escape)
-- Theme-Toggle (Space)
-- Language-Selector (Arrows, Enter)
-
-**Focus-Indikatoren:**
-```css
-.focus:outline-none {
-  @apply ring-2 ring-primary ring-offset-2;
-}
-```
-
-**Escape-Taste:**
-- Schließt User-Menu-Dropdown
-- Schließt Beiträge-Dropdown (collapsed)
-- Schließt Mobile-Drawer
-
-### 7.4 Color Contrast
-
-**Mindestkontrast:** 4.5:1 (normal text), 3:1 (large text)
-
-**DaisyUI Colors (geprüft):**
-- `text-base-content` auf `bg-base-200`: ✅ 7.2:1
-- `text-primary` auf `bg-base-100`: ✅ 5.1:1
-- `text-neutral-content` auf `bg-neutral`: ✅ 8.5:1
-
-### 7.5 Screen Reader Testing
-
-**Tools:**
-- NVDA (Windows)
-- VoiceOver (Mac)
-- JAWS (Windows)
-
-**Erwartetes Verhalten:**
-- "Main navigation, navigation landmark"
-- "Members, link, menu item"
-- "Toggle sidebar, button, expanded"
-- "User menu, button, has popup"
-
----
-
-## 8. Performance-Überlegungen
-
-### 8.1 CSS Transitions
-
-**Optimiert:**
-- `transition-[width]` - GPU-accelerated
-- `duration-300` - Wahrnehmbar, aber schnell
-- `ease-in-out` - Smooth Start/Stop
-
-**Vermeiden:**
-- `transition-all` - Zu generisch, Performance-Impact
-- Transitions auf `height: auto` - Nicht smooth
-
-### 8.2 JavaScript
-
-**Minimal:**
-- Hook läuft nur beim Mount
-- Toggle ist synchron (keine async Operations)
-- Keine Event-Listener-Lawine
-- Cleanup in `destroyed()`
-
-**localStorage:**
-- Synchron, aber schnell (Key/Value-Store)
-- Nur bei Toggle geschrieben (nicht bei jedem Render)
-
-### 8.3 CSS Paint
-
-**Minimierte Repaints:**
-- Width-Änderung triggert nur Reflow der Sidebar
-- Content-Bereich passt sich automatisch an (Flexbox)
-- Keine Layout-Thrashing
-
----
-
-## 9. Browser-Kompatibilität
-
-### 9.1 Unterstützte Browser
-
-| Browser | Mindestversion | Notizen |
-|---------|---------------|---------|
-| **Chrome** | 90+ | Vollständig unterstützt |
-| **Edge** | 90+ | Chromium-basiert |
-| **Firefox** | 88+ | Vollständig unterstützt |
-| **Safari** | 14+ | CSS-Transitions funktionieren |
-
-### 9.2 Features mit Fallbacks
-
-**CSS Grid/Flexbox:**
-- Alle Browser unterstützen
-
-**CSS Custom Properties:**
-- Alle Browser unterstützen (DaisyUI Themes)
-
-**localStorage:**
-- Alle Browser unterstützen
-- Fallback: State nur in Session
-
-**data-attributes:**
-- Alle Browser unterstützen
-
----
-
-## 10. Testing-Strategie
-

-  test "renders submenu items"
-end
-```
-
-### 10.2 Integration Tests
-
-**State-Management:**
-```elixir
-describe "sidebar state management" do
-  test "sidebar starts expanded by default"

-**Erstellt:** 2025-12-16  
-**Last Updated:** 2026-01-13  
-**Status:** ⚠️ Veraltet - Sidebar wurde bereits implementiert (2026-01-12, PR #260)  
-**Strategie:** Sequenzielle Tasks mit frischem Kontext pro Task
-
-> **Hinweis:** Diese Implementierungs-Anleitung wurde durch die tatsächliche Implementierung obsolet. Die Sidebar wurde erfolgreich implementiert. Siehe `sidebar-requirements-v2.md` für die finale Spezifikation.
-
----
-
-## Übersicht

-**Geschätzte Dauer:** 15 Minuten
-
-### Prompt:
-
-```
-Erstelle die CSS-Grundlage für die neue Sidebar in `assets/css/app.css`:
-
-## Schritt 1: Aufräumen
-1. Entferne ALLE bestehenden Custom CSS Variants für Sidebar:
-   - @custom-variant is-drawer-open
-   - @custom-variant is-drawer-close
-   - Alle .is-drawer-* Regeln
-
-2. Entferne alte Sidebar-spezifische Custom-Klassen
-
-## Schritt 2: Neue CSS-Regeln erstellen
-
-Erstelle CSS basierend auf `[data-sidebar-expanded]` Attribut:
-
-```css
-/* Desktop Sidebar Base */
-.sidebar {
-  @apply flex flex-col bg-base-200 min-h-screen;
-  @apply transition-[width] duration-300 ease-in-out;
-  width: 16rem; /* Expanded: w-64 */
-}
-
-/* Collapsed State */
-[data-sidebar-expanded="false"] .sidebar {

-}
-
-[data-sidebar-expanded="false"] .sidebar .expanded-only {
-  @apply hidden;
-}
-
-/* Tooltip - Only Show in Collapsed State */
-.sidebar .tooltip::before,
-.sidebar .tooltip::after {
-  @apply opacity-0 pointer-events-none;
-}
-
-[data-sidebar-expanded="false"] .sidebar .tooltip:hover::before,
-[data-sidebar-expanded="false"] .sidebar .tooltip:hover::after {

-## Task 5: Layout-Struktur
-
-**Agent:** Auto-Mode  
-**Geschätzte Dauer:** 20 Minuten
-
-### Prompt:
-
-```
-Implementiere die grundlegende Layout-Struktur für die Sidebar in `lib/mv_web/components/layouts.ex`:
-
-## Anforderungen:
-
-1. Nutze DaisyUI `drawer` + `drawer-open` Pattern
-2. Ein Container für Mobile UND Desktop (keine Duplikate!)
-3. `@inner_block` darf nur EINMAL gerendert werden
-4. `data-sidebar-expanded` Attribut auf root
-5. `phx-hook="SidebarState"` auf root
-6. `id="main-sidebar"` auf main content (für Tests)
-
-## Implementierung:
-
-Ersetze die bestehende `app/1` Funktion mit:
-
-```heex
-def app(assigns) do
-  club_name = get_club_name()
-  assigns = assign(assigns, :club_name, club_name)
-
-  ~H"""
-  <%= if @current_user do %>
-    <div id="app-layout" class="drawer lg:drawer-open" data-sidebar-expanded="true" phx-hook="SidebarState">
-      <input id="mobile-drawer" type="checkbox" class="drawer-toggle" />
-      
-      <div class="drawer-content flex flex-col">
-        <!-- Mobile Header (only visible on mobile) -->
-        <header class="lg:hidden sticky top-0 z-10 navbar bg-base-100 shadow-sm">
-          <label for="mobile-drawer" class="btn btn-square btn-ghost" aria-label={gettext("Open navigation menu")}>
-            <.icon name="hero-bars-3" class="size-6" aria-hidden="true" />
-          </label>
-          <span class="font-bold">{@club_name}</span>
-        </header>
-        
-        <!-- Main Content (shared between mobile and desktop) -->
-        <main id="main-sidebar" class="px-4 py-8 sm:px-6 lg:px-8">
-          <div class="mx-auto space-y-4 max-full">
-            {render_slot(@inner_block)}
-          </div>
-        </main>
-      </div>
-
-      <div class="drawer-side z-20">
-        <label for="mobile-drawer" aria-label="close sidebar" class="drawer-overlay lg:hidden"></label>
-        <!-- Sidebar Content wird in nächstem Task implementiert -->
-        <aside class="sidebar">
-          <div class="p-4">
-            <p>Sidebar Placeholder</p>
-          </div>
-        </aside>
-      </div>
-    </div>
-  <% else %>
-    <!-- Not logged in -->
-    <main class="px-4 py-8 sm:px-6">
-      <div class="mx-auto space-y-4 max-full">
-        {render_slot(@inner_block)}
-      </div>
-    </main>
-  <% end %>
-
-  <.flash_group flash={@flash} />
-  """
-end
-```
-
-## Wichtig:
-- @inner_block wird nur EINMAL gerendert (im drawer-content)
-- Mobile und Desktop teilen sich den gleichen main-content
-- Sidebar-Inhalt kommt in späteren Tasks
-
-## Testen:
-1. Kompiliere: `mix compile`
-2. Starte Server: `mix phx.server`
-3. Prüfe: Keine duplicate ID Fehler in Browser Console
-4. Prüfe: Layout funktioniert responsive
-5. Prüfe: Mobile Header erscheint nur auf Mobile
-```
-
-### Acceptance Criteria:
-- ✅ Layout-Struktur implementiert
-- ✅ Keine duplicate IDs
-- ✅ @inner_block nur einmal gerendert
-- ✅ Responsive funktioniert
-- ✅ Kompiliert ohne Fehler

-## Task 6: Sidebar Header Komponente
-
-**Agent:** Auto-Mode  
-**Geschätzte Dauer:** 20 Minuten
-
-### Prompt:
-
-```
-Implementiere die Sidebar-Header-Komponente in `lib/mv_web/components/layouts/sidebar.ex`:
-
-## Anforderungen:
-
-1. **Logo:**
-   - Immer `size-8` (32px)
-   - Immer sichtbar (kein Hide)
-   - Nur EIN Logo-Element
-   - Pfad: `/images/mila.svg`
-
-2. **Club-Name:**
-   - Text-Label mit CSS-Klasse `menu-label`
-   - Wird via CSS ausgeblendet (collapsed)
-   - `text-lg font-bold truncate`
-
-3. **Toggle-Button:**
-   - Nur auf Desktop sichtbar (responsive: `hidden lg:flex` oder `lg:block`)
-   - DaisyUI-konforme Button-Variante wählen:
-     * Option A: `btn btn-ghost btn-sm btn-square` (minimal, icon-only)
-     * Option B: `btn btn-ghost btn-sm` (mit etwas Padding)
-     * Option C: `btn btn-ghost btn-circle` (rund, falls besser zum Design passt)
-   - Icon-Strategie (wähle die beste Variante):
-     * Option A: Zwei Icons mit CSS-Klassen (`.sidebar-expanded-icon` / `.sidebar-collapsed-icon`)
-     * Option B: Ein Icon mit CSS transform (rotate bei collapsed)
-     * Option C: Ein Icon mit CSS content-swap (via ::before/::after)
-   - Event-Handler (wähle passende Variante):
-     * Option A: `onclick="toggleSidebar()"` (wenn global function vorhanden)
-     * Option B: `phx-click="toggle_sidebar"` (wenn LiveView event)
-     * Option C: `phx-hook="SidebarToggle"` (wenn Hook-basiert)
-   - ARIA: `aria-label={gettext("Toggle sidebar")}` und `aria-expanded` (wird via JS gesetzt)
-
-## Design-Überlegungen:
-
-- Button sollte sich harmonisch in den Header einfügen
-- Position: Rechts im Header (`ml-auto`)
-- Icon-Größe: `size-5` oder `size-4` (je nach Button-Größe)
-- Icon-Typ: Chevron (left/right) oder Arrow (left/right) - wähle das passendere
-- Hover-Effekt: Standard DaisyUI btn-ghost hover
-
-## Implementierung:
-
-Erstelle `sidebar_header/1` Funktion mit:
-- Flexbox-Layout für Header (Logo + Name + Toggle)
-- Responsive Toggle-Button
-- Icon-Swap-Mechanismus (wähle beste Variante)
-- Korrekte ARIA-Attribute
-
-## Empfehlung:
-
-Für DaisyUI-Konformität und Wartbarkeit:
-- Button: `btn btn-ghost btn-sm btn-square` (icon-only, minimal)
-- Icons: Zwei separate Icons mit CSS-Klassen (einfach, klar)
-- Event: `onclick="toggleSidebar()"` (wenn JS Hook vorhanden) ODER `phx-click` (wenn LiveView)
-
-## Beispiel-Struktur (als Orientierung):
-
-```elixir
-defp sidebar_header(assigns) do
-  ~H"""
-  <div class="flex items-center gap-3 p-4 border-b border-base-300">
-    <!-- Logo -->
-    <img src={~p"/images/mila.svg"} alt="Mila Logo" class="size-8 shrink-0" />
-    
-    <!-- Club Name -->
-    <span class="menu-label text-lg font-bold truncate">
-      {@club_name}
-    </span>
-    
-    <!-- Toggle Button (Desktop only) -->
-    <%= unless @mobile do %>
-      <button
-        type="button"
-        id="sidebar-toggle"
-        class="hidden lg:flex ml-auto btn btn-ghost btn-sm btn-square"
-        aria-label={gettext("Toggle sidebar")}
-        onclick="toggleSidebar()"
-      >
-        <!-- Icon-Implementierung nach gewählter Strategie -->
-      </button>
-    <% end %>
-  </div>
-  """
-end
-```
-
-## Integration in layouts.ex:
-
-Ersetze den Sidebar Placeholder in `layouts.ex`:
-
-```heex
-<aside class="sidebar">
-  <.sidebar_content current_user={@current_user} club_name={@club_name} mobile={false} />
-</aside>
-```
-
-## Testen:
-1. Kompiliere: `mix compile`
-2. Starte Server: `mix phx.server`
-3. Prüfe:
-   - Logo ist immer 32px groß
-   - Toggle-Button erscheint nur auf Desktop
-   - Button-Design passt zum Rest der Sidebar
-   - Icon wechselt beim Toggle
-   - Hover-Effekt funktioniert
-   - ARIA-Attribute korrekt
-   - Club-Name verschwindet beim Collapse (wenn toggleSidebar() funktioniert)
-```
-
-### Acceptance Criteria:
-- ✅ sidebar_header Komponente erstellt
-- ✅ Logo immer gleich groß
-- ✅ Toggle-Button nur auf Desktop
-- ✅ DaisyUI-konforme Button-Klassen verwendet
-- ✅ Icon-Swap funktioniert (egal welche Variante gewählt wurde)

-### Prompt:
-
-```
-Implementiere das verschachtelte "Beiträge"-Menü (Contributions) mit ZWEI verschiedenen Darstellungen je nach State.
-
-## Problem:
-Das Nested Menu muss sich anders verhalten als flat items:

-- **Collapsed:** Nutzt DaisyUI dropdown für Flyout rechts vom Icon
-
-## Anforderungen:
-
-1. **Nur EIN Hover-Effekt** (nicht doppelt)
-2. **Flyout erscheint rechts** vom Icon im collapsed state
-3. **Smooth transitions** zwischen states

-   - NUR EIN Hover-Effekt auf button
-
-3. **Toggle zwischen States:**
-   - Smooth Transition
-   - Keine Glitches
-   - Keine doppelten Elemente sichtbar
-
-## Debugging:
-
-Falls Probleme auftreten:
-- Browser DevTools: Prüfe, welche Elemente .expanded-menu-group oder .collapsed-menu-group haben
-- Prüfe data-sidebar-expanded Attribut im HTML
-- Prüfe z-index des Dropdowns (z-50)

-## Task 10: JavaScript State Management
-
-**Agent:** Auto-Mode  
-**Geschätzte Dauer:** 15 Minuten
-
-### Prompt:
-
-```
-Implementiere den vereinfachten SidebarState Hook in `assets/js/app.js`.
-
-## Ziel:
-
-Einfaches, robustes State-Management OHNE komplexe Event-Listener oder DOM-Manipulation.
-
-## Anforderungen:
-
-1. State in localStorage speichern
-2. State via data-attribute auf HTML-Element setzen
-3. Global `toggleSidebar()` Funktion bereitstellen
-4. aria-expanded auf Toggle-Button aktualisieren
-5. KEINE Checkbox-Manipulation
-6. KEINE Tab-Index-Verwaltung
-7. KEINE komplexen Event-Listener
-
-## Implementierung:
-
-Füge in `assets/js/app.js` zu den Hooks hinzu:
-
-```javascript
-Hooks.SidebarState = {
-  mounted() {
-    // Restore state from localStorage
-    const expanded = localStorage.getItem('sidebar-expanded') !== 'false';
-    this.setSidebarState(expanded);
-    
-    // Expose toggle function globally
-    window.toggleSidebar = () => {
-      const current = this.el.dataset.sidebarExpanded === 'true';
-      this.setSidebarState(!current);
-    };
-  },
-  
-  setSidebarState(expanded) {
-    // Update data-attribute (CSS reacts to this)
-    this.el.dataset.sidebarExpanded = expanded;
-    
-    // Persist to localStorage
-    localStorage.setItem('sidebar-expanded', expanded);
-    
-    // Update ARIA for accessibility
-    const toggleBtn = document.getElementById('sidebar-toggle');
-    if (toggleBtn) {
-      toggleBtn.setAttribute('aria-expanded', expanded);
-    }
-  },
-  
-  destroyed() {
-    // Cleanup
-    delete window.toggleSidebar;
-  }
-};
-```
-
-Stelle sicher, dass der Hook registriert ist:
-
-```javascript
-let liveSocket = new LiveSocket("/live", Socket, {
-  // ... existing config ...
-  hooks: Hooks
-})
-```
-
-## Testen:
-
-1. **Initial State:**
-   - Sidebar ist expanded (default)
-   - localStorage wird gesetzt
-
-2. **Toggle:**
-   - Klick auf Toggle-Button
-   - Sidebar animiert zu collapsed
-   - localStorage wird aktualisiert
-   - Icon wechselt (Chevron-left ↔ Chevron-right)
-
-3. **Persistence:**
-   - Toggle zu collapsed
-   - Seite neu laden
-   - Sidebar bleibt collapsed
-
-4. **Browser Console:**
-   - Keine Fehler
-   - `window.toggleSidebar()` ist aufrufbar
-   - `localStorage.getItem('sidebar-expanded')` zeigt korrekten Wert
-
-5. **ARIA:**
-   - Toggle-Button hat `aria-expanded="true"` oder `"false"`
-   - Wert ändert sich beim Toggle
-
-## Debugging:
-
-Falls Probleme:
-```javascript
-// In Browser Console:
-console.log(document.documentElement.dataset.sidebarExpanded);
-console.log(localStorage.getItem('sidebar-expanded'));
-window.toggleSidebar(); // Manuell testen
-```
-```
-
-### Acceptance Criteria:
-- ✅ Hook implementiert
-- ✅ State wird gespeichert (localStorage)
-- ✅ Toggle funktioniert
-- ✅ CSS reagiert auf data-attribute
-- ✅ ARIA korrekt gesetzt
-- ✅ Keine Console-Fehler
-- ✅ Persistence funktioniert

-## Task 11: Mobile Header Integration
-
-**Agent:** Auto-Mode  
-**Geschätzte Dauer:** 10 Minuten
-
-### Prompt:
-
-```
-Prüfe und optimiere die Mobile-Header-Integration.
-
-## Anforderungen:
-
-1. Mobile Header ist bereits in `layouts.ex` implementiert
-2. Hamburger-Menü öffnet Sidebar
-3. Header nur auf Mobile sichtbar (`lg:hidden`)
-4. Overlay schließt Sidebar
-
-## Zu prüfen:
-
-Stelle sicher, dass in `layouts.ex` folgendes korrekt ist:
-
-```heex
-<header class="lg:hidden sticky top-0 z-10 navbar bg-base-100 shadow-sm">
-  <label for="mobile-drawer" class="btn btn-square btn-ghost" aria-label={gettext("Open navigation menu")}>
-    <.icon name="hero-bars-3" class="size-6" aria-hidden="true" />
-  </label>
-  <span class="font-bold">{@club_name}</span>
-</header>
-```
-
-Und im drawer-side:
-
-```heex
-<label for="mobile-drawer" aria-label="close sidebar" class="drawer-overlay lg:hidden"></label>
-```
-
-## Testen:
-
-1. **Mobile View (< 1024px):**
-   - Header erscheint am oberen Rand
-   - Hamburger-Icon sichtbar
-   - Club-Name neben Hamburger
-
-2. **Hamburger-Click:**
-   - Sidebar schiebt von links rein
-   - Overlay verdunkelt Content
-   - Sidebar ist vollständig sichtbar
-
-3. **Overlay-Click:**
-   - Sidebar schließt sich
-   - Overlay verschwindet
-   - Content wieder normal
-
-4. **Desktop View (≥ 1024px):**
-   - Header verschwindet
-   - Sidebar ist persistent sichtbar
-   - Kein Hamburger-Icon
-   - Toggle-Button erscheint in Sidebar
-
-5. **Responsive Breakpoint:**
-   - Smooth Transition bei Resize
-   - Keine Layout-Breaks
-   - Sidebar-State bleibt erhalten
-
-## Optional: CSS-Verbesserungen
-
-Falls Mobile-Sidebar zu schmal ist, füge in `app.css` hinzu:
-
-```css
-/* Mobile Drawer Width */
-@media (max-width: 1023px) {
-  .drawer-side .sidebar {
-    width: 16rem; /* w-64 auch auf Mobile */
-  }
-}
-```
-```
-
-### Acceptance Criteria:
-- ✅ Mobile Header funktioniert
-- ✅ Hamburger öffnet Sidebar
-- ✅ Overlay schließt Sidebar
-- ✅ Header nur auf Mobile

-  ## Features
-  - Create new custom field values with member and type selection
-  - Edit existing custom field values
-  - Value input adapts to custom field type (string, integer, boolean, date, email)
-  - Real-time validation
-
-  ## Form Fields
-  **Required:**
-  - member - Select which member owns this custom field value
-  - custom_field - Select the type (defines value type)
-  - value - The actual value (input type depends on custom field type)
-
-  ## Value Types
-  The form dynamically renders appropriate inputs based on custom field type:
-  - String: text input
-  - Integer: number input
-  - Boolean: checkbox
-  - Date: date picker
-  - Email: email input with validation
-
-  ## Events
-  - `validate` - Real-time form validation
-  - `save` - Submit form (create or update custom field value)
-
-  ## Note
-  Custom field values are typically managed through the member edit form,
-  not through this standalone form.

-# Documentation Sync - Code Adjustments Todo List
-
-**Created:** 2026-01-13  
-**Purpose:** List of all code adjustments identified based on documentation synchronization
-
-
-## Code Adjustments (Priority: Low)
-
-### 1. Domain Public API Documentation Incomplete
-
-**Problem:** The `@moduledoc` in domain modules does not list all public functions.
-
-**Affected Files:**
-- `lib/membership/membership.ex` - Missing functions in Public API:
-  - `list_required_custom_fields/0`
-  - `update_member_field_visibility/2`
-  - `update_single_member_field_visibility/3`
-- `lib/accounts/accounts.ex` - Very short Public API documentation, could be more detailed
-- `lib/membership_fees/membership_fees.ex` - Public API is complete, but could more clearly document that LiveViews use direct Ash calls
-
-**Priority:** Low (Documentation, no functionality affected)
-
-**Recommendation:** Update Public API sections in all domain modules to list all public functions.
-
-### 2. Outdated Comments in MemberLive.Form
-
-**Problem:** `@moduledoc` in `lib/mv_web/live/member_live/form.ex` still mentions "Payment Data: Mockup section (not editable)", but Membership Fees are now fully implemented.
-
-**Affected File:**
-- `lib/mv_web/live/member_live/form.ex` (Line 16)
-
-**Priority:** Low (Documentation, no functionality affected)
-
-**Recommendation:** Update `@moduledoc` to reflect the current status.
-
-### 3. Mv.Accounts Domain Public API Missing Completely
-
-**Problem:** The `@moduledoc` in `lib/accounts/accounts.ex` does not mention any Public API functions, although several are defined.
-
-**Affected File:**
-- `lib/accounts/accounts.ex` - Missing Public API documentation for:
-  - `create_user/1`
-  - `list_users/0`
-  - `update_user/2`
-  - `destroy_user/1`
-  - `create_register_with_rauthy/1`
-  - `read_sign_in_with_rauthy/1`
-
-**Priority:** Low (Documentation, no functionality affected)
-
-**Recommendation:** Add Public API section to `@moduledoc`, similar to other domain modules.
-
-### 4. Mv.Authorization Domain Public API Missing get_role/1
-
-**Problem:** The `@moduledoc` in `lib/mv/authorization/authorization.ex` does not list `get_role/1` in the Public API, although it is defined.
-
-**Affected File:**
-- `lib/mv/authorization/authorization.ex` - Missing function in Public API:
-  - `get_role/1` (is defined, but not mentioned in Public API)
-
-**Priority:** Low (Documentation, no functionality affected)
-
-**Recommendation:** Add `get_role/1` to the Public API list.
-
-### 5. Remove Deprecated Implementations
-
-**Problem:** `lib/mv_web/live/custom_field_value_live/show.ex` `MvWeb.ContributionTypeLive.Index` and `MvWeb.ContributionPeriodLive.Show` are deprecated, they should be removed.
-
-### 6. Missing Tests for Some LiveViews
-
-**Problem:** Some LiveViews do not have corresponding test files.
-
-**Affected LiveViews:**
-- `MvWeb.UserLive.Show` - No test present
-- `MvWeb.RoleLive.Show` - No test present
-
-**Priority:** Medium (Test coverage could be improved)
-
-**Recommendation:** Add tests for the three Show LiveViews to ensure complete test coverage.
-
-### 7. Mv.Accounts.Token @moduledoc Too Short
-
-**Problem:** The `@moduledoc` in `lib/accounts/token.ex` is very short and not informative.
-
-**Affected File:**
-- `lib/accounts/token.ex` - Currently only: "AshAuthentication specific ressource"
-
-**Priority:** Low (Documentation, no functionality affected)
-
-**Recommendation:** Expand @moduledoc to explain that this is an AshAuthentication Token Resource and is used for session management.
-
-### 8. PageController Missing @moduledoc
-
-**Problem:** The `@moduledoc` in `lib/mv_web/controllers/page_controller.ex` is completely missing.
-
-**Affected File:**
-- `lib/mv_web/controllers/page_controller.ex` - No @moduledoc present
-
-**Priority:** Low (Documentation, no functionality affected)
-
-**Recommendation:** Add @moduledoc to explain that this controller renders the homepage.
-
-**Note:** Other controller modules (Router, Endpoint, Telemetry) also do not have @moduledoc, but this is common and acceptable for standard Phoenix modules.
-
-## Analysis Summary
-
-### Found Inconsistencies
-
-**1. Domain Public API Documentation Incomplete** (see Code Adjustments #1)
-**2. Outdated Comments in MemberLive.Form** (see Code Adjustments #2)
-**3. Mv.Accounts Domain Public API Missing Completely** (see Code Adjustments #3)
-**4. Mv.Authorization Domain Public API Missing get_role/1** (see Code Adjustments #4)
-**5. CustomFieldValueLive.Show is Deprecated** (see Code Adjustments #5)
-**6. Missing Tests for Some LiveViews** (see Code Adjustments #6)
-**7. Mv.Accounts.Token @moduledoc Too Short** (see Code Adjustments #7)
-**8. PageController Missing @moduledoc** (see Code Adjustments #8)

Subject: [PATCH 15/54] Add System Actor helper for systemic operations

Introduce Mv.Helpers.SystemActor module with lazy loading
for operations that must always run regardless of user permissions.
System actor has admin role and auto-creates in test environment.

+  Provides access to the system actor for systemic operations.
+
+  The system actor is a user with admin permissions that is used
+  for operations that must always run regardless of user permissions:
+  - Email synchronization
+  - Email uniqueness validation
+  - Cycle generation (if mandatory)
+  - Background jobs
+  - Seeds

+
+      # Get system actor for systemic operations
+      system_actor = Mv.Helpers.SystemActor.get_system_actor()
+      Ash.read(query, actor: system_actor)
+
+  ## Implementation
+
+  The system actor is cached in an Agent for performance. On first access,
+  it attempts to load a user with email "system@mila.local" and admin role.
+  If that user doesn't exist, it falls back to the admin user from seeds
+  (identified by ADMIN_EMAIL environment variable or "admin@localhost").
+
+  ## Caching
+
+  The system actor is cached in an Agent to avoid repeated database queries.
+  The cache is invalidated on application restart. For long-running applications,
+  consider implementing cache invalidation on role changes.
+
+  ## Security
+
+  The system actor should NEVER be used for user-initiated actions. It is
+  only for systemic operations that must bypass user permissions.

   ## Authorization
 
-  This module runs systemically and accepts optional actor parameters.
-  When called from hooks/changes, actor is extracted from changeset context.
-  When called directly, actor should be provided for proper authorization.
+  This module runs systemically and uses the system actor for all operations.
+  This ensures that cycle generation always works, regardless of user permissions.
 
-  All functions accept an optional `actor` parameter in the `opts` keyword list
-  that is passed to Ash operations to ensure proper authorization checks are performed.
+  All functions use `Mv.Helpers.SystemActor.get_system_actor/0` to bypass
+  user permission checks, as cycle generation is a mandatory side effect.

-### 3.3 Ash Framework
+### 3.3 System Actor Pattern
+
+**When to Use System Actor:**
+
+Some operations must always run regardless of user permissions. These are **systemic operations** that are mandatory side effects:
+
+- **Email synchronization** (Member ↔ User)
+- **Email uniqueness validation** (data integrity requirement)
+- **Cycle generation** (if defined as mandatory side effect)
+- **Background jobs**
+- **Seeds**
+
+**Implementation:**
+
+Use `Mv.Helpers.SystemActor.get_system_actor/0` for all systemic operations:
+
+```elixir
+# Good - Email sync uses system actor
+def get_linked_member(user) do
+  system_actor = SystemActor.get_system_actor()
+  opts = Helpers.ash_actor_opts(system_actor)
+  
+  case Ash.get(Mv.Membership.Member, id, opts) do
+    {:ok, member} -> member
+    {:error, _} -> nil
+  end
+end
+
+# Bad - Using user actor for systemic operation
+def get_linked_member(user, actor) do
+  opts = Helpers.ash_actor_opts(actor)  # May fail if user lacks permissions!
+  # ...
+end
+```
+
+**System Actor Details:**
+
+- System actor is a user with admin role (email: "system@mila.local")
+- Cached in Agent for performance
+- Falls back to admin user from seeds if system user doesn't exist
+- Should NEVER be used for user-initiated actions (only systemic operations)
+
+**User Mode vs System Mode:**
+
+- **User Mode**: User-initiated actions use the actual user actor, policies are enforced
+- **System Mode**: Systemic operations use system actor, bypass user permissions
+
+### 3.4 Ash Framework

+# Policy Pattern: Bypass vs. HasPermission
+
+**Date:** 2026-01-22  
+**Status:** Implemented and Tested  
+**Applies to:** User Resource, Member Resource
+
+---
+
+## Summary
+
+For filter-based permissions (`scope :own`, `scope :linked`), we use a **two-tier authorization pattern**:
+
+1. **Bypass with `expr()` for READ operations** - Handles list queries via auto_filter
+2. **HasPermission for UPDATE/CREATE/DESTROY** - Uses scope from PermissionSets when record is present
+
+This pattern ensures that the scope concept in PermissionSets is actually used and not redundant.
+
+---
+
+## The Problem
+
+### Initial Assumption (INCORRECT)
+
+> "No separate Own Credentials Bypass needed, as all permission sets already have User read/update :own. HasPermission with scope :own handles this correctly."
+
+This assumption was based on the idea that `HasPermission` returning `{:filter, expr(...)}` would automatically trigger Ash's `auto_filter` for list queries.
+
+### Reality
+
+**When HasPermission returns `{:filter, expr(...)}`:**
+
+1. `strict_check` is called first
+2. For list queries (no record yet), `strict_check` returns `{:ok, false}`
+3. Ash **STOPS** evaluation and does **NOT** call `auto_filter`
+4. Result: List queries fail with empty results ❌
+
+**Example:**
+```elixir
+# This FAILS for list queries:
+policy action_type([:read, :update]) do
+  authorize_if Mv.Authorization.Checks.HasPermission
+end
+
+# User tries to list all users:
+Ash.read(User, actor: user)
+# Expected: Returns [user] (filtered to own record)
+# Actual: Returns [] (empty list)
+```
+
+---
+
+## The Solution
+
+### Pattern: Bypass for READ, HasPermission for UPDATE
+
+**User Resource Example:**
+
+```elixir
+policies do
+  # Bypass for READ (handles list queries via auto_filter)
+  bypass action_type(:read) do
+    description "Users can always read their own account"
+    authorize_if expr(id == ^actor(:id))
+  end
+  
+  # HasPermission for UPDATE (scope :own works with changesets)
+  policy action_type([:read, :create, :update, :destroy]) do
+    description "Check permissions from user's role and permission set"
+    authorize_if Mv.Authorization.Checks.HasPermission
+  end
+end
+```
+
+**Why This Works:**
+
+| Operation | Record Available? | Method | Result |
+|-----------|-------------------|--------|--------|
+| **READ (list)** | ❌ No | `bypass` with `expr()` | Ash applies expr as SQL WHERE → ✅ Filtered list |
+| **READ (single)** | ✅ Yes | `bypass` with `expr()` | Ash evaluates expr → ✅ true/false |
+| **UPDATE** | ✅ Yes (changeset) | `HasPermission` with `scope :own` | strict_check evaluates record → ✅ Authorized |
+| **CREATE** | ✅ Yes (changeset) | `HasPermission` with `scope :own` | strict_check evaluates record → ✅ Authorized |
+| **DESTROY** | ✅ Yes | `HasPermission` with `scope :own` | strict_check evaluates record → ✅ Authorized |
+
+---
+
+## Why `scope :own` Is NOT Redundant
+
+### The Question
+
+> "If we use a bypass with `expr(id == ^actor(:id))` for READ, isn't `scope :own` in PermissionSets redundant?"
+
+### The Answer: NO! ✅
+
+**`scope :own` is ONLY used for operations where a record is present:**
+
+```elixir
+# PermissionSets.ex
+%{resource: "User", action: :read, scope: :own, granted: true},   # Not used (bypass handles it)
+%{resource: "User", action: :update, scope: :own, granted: true}, # USED by HasPermission ✅
+```
+
+**Test Proof:**
+
+```elixir
+# test/mv/accounts/user_policies_test.exs:82
+test "can update own email", %{user: user} do
+  new_email = "updated@example.com"
+  
+  # This works via HasPermission with scope :own (NOT via bypass)
+  {:ok, updated_user} =
+    user
+    |> Ash.Changeset.for_update(:update_user, %{email: new_email})
+    |> Ash.update(actor: user)
+  
+  assert updated_user.email == Ash.CiString.new(new_email)
+end
+# ✅ Test passes - proves scope :own is used!
+```
+
+---
+
+## Consistency Across Resources
+
+### User Resource
+
+```elixir
+# Bypass for READ list queries
+bypass action_type(:read) do
+  authorize_if expr(id == ^actor(:id))
+end
+
+# HasPermission for UPDATE (uses scope :own from PermissionSets)
+policy action_type([:read, :create, :update, :destroy]) do
+  authorize_if Mv.Authorization.Checks.HasPermission
+end
+```
+
+**PermissionSets:**
+- `own_data`, `read_only`, `normal_user`: `scope :own` for read/update
+- `admin`: `scope :all` for all operations
+
+### Member Resource
+
+```elixir
+# Bypass for READ list queries
+bypass action_type(:read) do
+  authorize_if expr(id == ^actor(:member_id))
+end
+
+# HasPermission for UPDATE (uses scope :linked from PermissionSets)
+policy action_type([:read, :create, :update, :destroy]) do
+  authorize_if Mv.Authorization.Checks.HasPermission
+end
+```
+
+**PermissionSets:**
+- `own_data`: `scope :linked` for read/update
+- `read_only`: `scope :all` for read (no update permission)
+- `normal_user`, `admin`: `scope :all` for all operations
+
+---
+
+## Technical Deep Dive
+
+### Why Does `expr()` in Bypass Work?
+
+**Ash treats `expr()` natively in two contexts:**
+
+1. **strict_check** (single record):
+   - Ash evaluates the expression against the record
+   - Returns true/false based on match
+
+2. **auto_filter** (list queries):
+   - Ash compiles the expression to SQL WHERE clause
+   - Applies filter directly in database query
+
+**Example:**
+```elixir
+bypass action_type(:read) do
+  authorize_if expr(id == ^actor(:id))
+end
+
+# For list query: Ash.read(User, actor: user)
+# Compiled SQL: SELECT * FROM users WHERE id = $1 (user.id)
+# Result: [user] ✅
+```
+
+### Why Doesn't HasPermission Trigger auto_filter?
+
+**HasPermission.strict_check logic:**
+
+```elixir
+def strict_check(actor, authorizer, _opts) do
+  # ...
+  case check_permission(...) do
+    {:filter, filter_expr} ->
+      if record do
+        # Evaluate filter against record
+        evaluate_filter_for_strict_check(filter_expr, actor, record, resource_name)
+      else
+        # No record (list query) - return false
+        # Ash STOPS here, does NOT call auto_filter
+        {:ok, false}
+      end
+  end
+end
+```
+
+**Why return false instead of :unknown?**
+
+We tested returning `:unknown`, but Ash's policy evaluation still didn't reliably call `auto_filter`. The `bypass` with `expr()` is the only consistent solution.
+
+---
+
+## Design Principles
+
+### 1. Consistency
+
+Both User and Member follow the same pattern:
+- Bypass for READ (list queries)
+- HasPermission for UPDATE/CREATE/DESTROY (with scope)
+
+### 2. Scope Concept Is Essential
+
+PermissionSets define scopes for all operations:
+- `:own` - User can access their own records
+- `:linked` - User can access linked records (e.g., their member)
+- `:all` - User can access all records (admin)
+
+**These scopes are NOT redundant** - they are used for UPDATE/CREATE/DESTROY.
+
+### 3. Bypass Is a Technical Workaround
+
+The bypass is not a design choice but a **technical necessity** due to Ash's policy evaluation behavior:
+- Ash doesn't call `auto_filter` when `strict_check` returns `false`
+- `expr()` in bypass is handled natively by Ash for both contexts
+- This is consistent with Ash's documentation and best practices
+
+---
+
+## Test Coverage
+
+### User Resource Tests
+
+**File:** `test/mv/accounts/user_policies_test.exs`
+
+**Coverage:**
+- ✅ 31 tests: 30 passing, 1 skipped
+- ✅ All 4 permission sets: `own_data`, `read_only`, `normal_user`, `admin`
+- ✅ READ operations (list and single) via bypass
+- ✅ UPDATE operations via HasPermission with `scope :own`
+- ✅ Admin operations via HasPermission with `scope :all`
+- ✅ AshAuthentication bypass (registration/login)
+- ✅ NoActor bypass (test environment)
+
+**Key Tests Proving Pattern:**
+
+```elixir
+# Test 1: READ list uses bypass (returns filtered list)
+test "list users returns only own user", %{user: user} do
+  {:ok, users} = Ash.read(Accounts.User, actor: user, domain: Mv.Accounts)
+  assert length(users) == 1  # Filtered to own user ✅
+  assert hd(users).id == user.id
+end
+
+# Test 2: UPDATE uses HasPermission with scope :own
+test "can update own email", %{user: user} do
+  {:ok, updated_user} =
+    user
+    |> Ash.Changeset.for_update(:update_user, %{email: "new@example.com"})
+    |> Ash.update(actor: user)
+  
+  assert updated_user.email  # Uses scope :own from PermissionSets ✅
+end
+
+# Test 3: Admin uses HasPermission with scope :all
+test "admin can update other users", %{admin: admin, other_user: other_user} do
+  {:ok, updated_user} =
+    other_user
+    |> Ash.Changeset.for_update(:update_user, %{email: "admin-changed@example.com"})
+    |> Ash.update(actor: admin)
+  
+  assert updated_user.email  # Uses scope :all from PermissionSets ✅
+end
+```
+
+---
+
+## Lessons Learned
+
+1. **Don't assume** that returning a filter from `strict_check` will trigger `auto_filter` - test it!
+2. **Bypass with `expr()` is necessary** for list queries with filter-based permissions
+3. **Scope concept is NOT redundant** - it's used for operations with records (UPDATE/CREATE/DESTROY)
+4. **Consistency matters** - following the same pattern across resources improves maintainability
+5. **Documentation is key** - explaining WHY the pattern exists prevents future confusion
+
+---
+
+## Future Considerations
+
+### If Ash Changes Policy Evaluation
+
+If a future version of Ash reliably calls `auto_filter` when `strict_check` returns `:unknown` or `{:filter, expr}`:
+
+1. We could **remove** the bypass for READ
+2. Keep only the HasPermission policy for all operations
+3. Update tests to verify the new behavior
+
+**However, for now (Ash 3.13.1), the bypass pattern is necessary and correct.**

+
+## Bypass vs. HasPermission: When to Use Which?
+
+**Key Finding:** For filter-based permissions (`scope :own`, `scope :linked`), we use a **two-tier approach**:
+
+1. **Bypass with `expr()` for READ** - Handles list queries (auto_filter)
+2. **HasPermission for UPDATE/CREATE/DESTROY** - Handles operations with records
+
+### Why This Pattern?
+
+**The Problem with HasPermission for List Queries:**
+
+When `HasPermission` returns `{:filter, expr(...)}` for `scope :own` or `scope :linked`:
+- `strict_check` returns `{:ok, false}` for queries without a record
+- Ash does **NOT** reliably call `auto_filter` when `strict_check` returns `false`
+- Result: List queries fail ❌
+
+**The Solution:**
+
+Use `bypass` with `expr()` directly for READ operations:
+- Ash handles `expr()` natively for both `strict_check` and `auto_filter`
+- List queries work correctly ✅
+- Single-record reads work correctly ✅
+
+### Pattern Summary
+
+| Operation | Has Record? | Use | Why |
+|-----------|-------------|-----|-----|
+| **READ (list)** | ❌ No | `bypass` with `expr()` | Triggers auto_filter |
+| **READ (single)** | ✅ Yes | `bypass` with `expr()` | expr() evaluates to true/false |
+| **UPDATE** | ✅ Yes (changeset) | `HasPermission` | strict_check can evaluate record |
+| **CREATE** | ✅ Yes (changeset) | `HasPermission` | strict_check can evaluate record |
+| **DESTROY** | ✅ Yes | `HasPermission` | strict_check can evaluate record |
+
+### Is scope :own/:linked Still Useful?
+
+**YES! ✅** The scope concept is essential:
+
+1. **Documentation** - Clearly expresses intent in PermissionSets
+2. **UPDATE/CREATE/DESTROY** - Works perfectly via HasPermission when record is present
+3. **Consistency** - All permissions are centralized in PermissionSets
+4. **Maintainability** - Easy to see what each role can do

+The bypass is a **technical workaround** for Ash's auto_filter limitation, not a replacement for the scope concept.
+
+### Consistency Across Resources
+
+Both `User` and `Member` follow this pattern:
+
+- **User**: Bypass for READ (`id == ^actor(:id)`), HasPermission for UPDATE (`scope :own`)
+- **Member**: Bypass for READ (`id == ^actor(:member_id)`), HasPermission for UPDATE (`scope :linked`)
+
+This ensures consistent behavior and predictable authorization logic throughout the application.

 ### User Resource Policies
 
 **Location:** `lib/mv/accounts/user.ex`
 
-**Special Case:** Users can ALWAYS read/update their own credentials, regardless of role.
+**Pattern:** Bypass for READ (list queries), HasPermission for UPDATE (with scope :own).
+
+**Key Insight:** Bypass with `expr()` is needed ONLY for READ list queries because HasPermission's strict_check cannot properly trigger auto_filter. UPDATE operations work correctly via HasPermission because a changeset with record is available.
 
 ```elixir
 defmodule Mv.Accounts.User do
   use Ash.Resource, ...
   
   policies do
-    # SPECIAL CASE: Users can always access their own account
-    # This takes precedence over permission checks
-    policy action_type([:read, :update]) do
-      description "Users can always read and update their own account"
+    # 1. AshAuthentication Bypass (registration/login without actor)
+    bypass AshAuthentication.Checks.AshAuthenticationInteraction do
+      authorize_if always()
+    end
+    
+    # 2. NoActor Bypass (test environment only, for test fixtures)
+    bypass action_type([:create, :read, :update, :destroy]) do
+      authorize_if Mv.Authorization.Checks.NoActor
+    end
+    
+    # 3. SPECIAL CASE: Users can always READ their own account
+    # Bypass needed for list queries (expr() triggers auto_filter in Ash)
+    # UPDATE is handled by HasPermission below (scope :own works with changesets)
+    bypass action_type(:read) do
+      description "Users can always read their own account"
       authorize_if expr(id == ^actor(:id))
     end
     
-    # GENERAL: Other operations require permission
-    # (e.g., admin reading/updating other users, admin destroying users)
+    # 4. GENERAL: Check permissions from user's role
+    # - :own_data → can UPDATE own user (scope :own via HasPermission)
+    # - :read_only → can UPDATE own user (scope :own via HasPermission)
+    # - :normal_user → can UPDATE own user (scope :own via HasPermission)
+    # - :admin → can read/create/update/destroy all users (scope :all)
     policy action_type([:read, :create, :update, :destroy]) do
-      description "Check permissions from user's role"
+      description "Check permissions from user's role and permission set"
       authorize_if Mv.Authorization.Checks.HasPermission
     end
     
-    # DEFAULT: Forbid if no policy matched
-    policy action_type([:read, :create, :update, :destroy]) do
-      forbid_if always()
-    end
+    # 5. DEFAULT: Ash implicitly forbids if no policy authorizes (fail-closed)
   end
   
   # ...
 end
 ```
 
+**Why Bypass for READ but not UPDATE?**
+
+- **READ list queries** (`Ash.read(User, actor: user)`): No record at strict_check time → HasPermission returns `{:ok, false}` → auto_filter not called → bypass with `expr()` needed ✅
+- **UPDATE operations** (`Ash.update(changeset, actor: user)`): Changeset contains record → HasPermission can evaluate `scope :own` correctly → works via HasPermission ✅

 ### Member Resource Policies

+# User Resource Authorization Policies - Implementation Summary
+
+**Date:** 2026-01-22  
+**Status:** ✅ COMPLETED
+
+---
+
+## Overview
+
+Successfully implemented authorization policies for the User resource following the Bypass + HasPermission pattern, ensuring consistency with Member resource policies and proper use of the scope concept from PermissionSets.
+
+---
+
+## What Was Implemented
+
+### 1. Policy Structure in `lib/accounts/user.ex`
+
+```elixir
+policies do
+  # 1. AshAuthentication Bypass
+  bypass AshAuthentication.Checks.AshAuthenticationInteraction do
+    authorize_if always()
+  end
+  
+  # 2. NoActor Bypass (test environment only)
+  bypass action_type([:create, :read, :update, :destroy]) do
+    authorize_if Mv.Authorization.Checks.NoActor
+  end
+  
+  # 3. Bypass for READ (list queries via auto_filter)
+  bypass action_type(:read) do
+    description "Users can always read their own account"
+    authorize_if expr(id == ^actor(:id))
+  end
+  
+  # 4. HasPermission for all operations (uses scope from PermissionSets)
+  policy action_type([:read, :create, :update, :destroy]) do
+    description "Check permissions from user's role and permission set"
+    authorize_if Mv.Authorization.Checks.HasPermission
+  end
+end
+```
+
+### 2. Test Suite in `test/mv/accounts/user_policies_test.exs`
+
+**Coverage:**
+- ✅ 31 tests total: 30 passing, 1 skipped
+- ✅ All 4 permission sets tested: `own_data`, `read_only`, `normal_user`, `admin`
+- ✅ READ operations (list and single record)
+- ✅ UPDATE operations (own and other users)
+- ✅ CREATE operations (admin only)
+- ✅ DESTROY operations (admin only)
+- ✅ AshAuthentication bypass (registration/login)
+- ✅ NoActor bypass (test environment)
+
+---
+
+## Key Design Decisions
+
+### Decision 1: Bypass for READ, HasPermission for UPDATE
+
+**Rationale:**
+- READ list queries have no record at `strict_check` time
+- `HasPermission` returns `{:ok, false}` for queries without record
+- Ash doesn't call `auto_filter` when `strict_check` returns `false`
+- `expr()` in bypass is handled natively by Ash for `auto_filter`
+
+**Result:**
+- Bypass handles READ list queries ✅
+- HasPermission handles UPDATE with `scope :own` ✅
+- No redundancy - both are necessary ✅
+
+### Decision 2: No Explicit `forbid_if always()`
+
+**Rationale:**
+- Ash implicitly forbids if no policy authorizes (fail-closed by default)
+- Explicit `forbid_if always()` at the end breaks tests
+- It would forbid valid operations that should be authorized by previous policies
+
+**Result:**
+- Policies rely on Ash's implicit forbid ✅
+- Tests pass with this approach ✅
+
+### Decision 3: Consistency with Member Resource
+
+**Rationale:**
+- Member resource uses same pattern: Bypass for READ, HasPermission for UPDATE
+- Consistent patterns improve maintainability and predictability
+- Developers can understand authorization logic across resources
+
+**Result:**
+- User and Member follow identical pattern ✅
+- Authorization logic is consistent throughout the app ✅
+
+---
+
+## The Scope Concept Is NOT Redundant
+
+### Initial Concern
+
+> "If we use a bypass with `expr(id == ^actor(:id))` for READ, isn't `scope :own` in PermissionSets redundant?"
+
+### Resolution
+
+**NO! The scope concept is essential:**
+
+1. **Documentation** - `scope :own` clearly expresses intent in PermissionSets
+2. **UPDATE operations** - `scope :own` is USED by HasPermission when changeset contains record
+3. **Admin operations** - `scope :all` allows admins full access
+4. **Maintainability** - All permissions centralized in one place
+
+**Test Proof:**
+
+```elixir
+test "can update own email", %{user: user} do
+  # This works via HasPermission with scope :own (NOT bypass)
+  {:ok, updated_user} =
+    user
+    |> Ash.Changeset.for_update(:update_user, %{email: "new@example.com"})
+    |> Ash.update(actor: user)
+  
+  assert updated_user.email  # ✅ Proves scope :own is used
+end
+```
+
+---
+
+## Documentation Updates
+
+### 1. Created `docs/policy-bypass-vs-haspermission.md`
+
+Comprehensive documentation explaining:
+- Why bypass is needed for READ
+- Why HasPermission works for UPDATE
+- Technical deep dive into Ash policy evaluation
+- Test coverage proving the pattern
+- Lessons learned
+
+### 2. Updated `docs/roles-and-permissions-architecture.md`
+
+- Added "Bypass vs. HasPermission: When to Use Which?" section
+- Updated User Resource Policies section with correct implementation
+- Updated Member Resource Policies section for consistency
+- Added pattern comparison table
+
+### 3. Updated `docs/roles-and-permissions-implementation-plan.md`
+
+- Marked Issue #8 as COMPLETED ✅
+- Added implementation details
+- Documented why bypass is needed
+- Added test results
+
+---
+
+## Test Results
+
+### All Relevant Tests Pass
+
+```bash
+mix test test/mv/accounts/user_policies_test.exs \
+         test/mv/authorization/checks/has_permission_test.exs \
+         test/mv/membership/member_policies_test.exs
+
+# Results:
+# 75 tests: 74 passing, 1 skipped
+# ✅ User policies: 30/31 (1 skipped)
+# ✅ HasPermission check: 21/21
+# ✅ Member policies: 23/23
+```
+
+### Specific Test Coverage
+
+**Own Data Access (All Roles):**
+- ✅ Can read own user record (via bypass)
+- ✅ Can update own email (via HasPermission with scope :own)
+- ✅ Cannot read other users (filtered by bypass)
+- ✅ Cannot update other users (forbidden by HasPermission)
+- ✅ List returns only own user (auto_filter via bypass)
+
+**Admin Access:**
+- ✅ Can read all users (HasPermission with scope :all)
+- ✅ Can update other users (HasPermission with scope :all)
+- ✅ Can create users (HasPermission with scope :all)
+- ✅ Can destroy users (HasPermission with scope :all)
+
+**AshAuthentication:**
+- ✅ Registration works without actor
+- ✅ OIDC registration works
+- ✅ OIDC sign-in works
+
+**Test Environment:**
+- ✅ Operations without actor work in test environment
+- ✅ NoActor bypass correctly detects compile-time environment
+
+---
+
+## Files Changed
+
+### Implementation
+1. ✅ `lib/accounts/user.ex` - Added policies block (lines 271-315)
+2. ✅ `lib/mv/authorization/checks/has_permission.ex` - Added User resource support in `evaluate_filter_for_strict_check`
+
+### Tests
+3. ✅ `test/mv/accounts/user_policies_test.exs` - Created comprehensive test suite (435 lines)
+4. ✅ `test/mv/authorization/checks/has_permission_test.exs` - Updated to expect `false` instead of `:unknown`
+
+### Documentation
+5. ✅ `docs/policy-bypass-vs-haspermission.md` - New comprehensive guide (created)
+6. ✅ `docs/roles-and-permissions-architecture.md` - Updated User and Member sections
+7. ✅ `docs/roles-and-permissions-implementation-plan.md` - Marked Issue #8 as completed
+8. ✅ `docs/user-resource-policies-implementation-summary.md` - This file (created)
+
+---
+
+## Lessons Learned
+
+### 1. Test Before Assuming
+
+The initial plan assumed HasPermission with `scope :own` would be sufficient. Testing revealed that Ash's policy evaluation doesn't reliably call `auto_filter` when `strict_check` returns `false` or `:unknown`.
+
+### 2. Bypass Is Not a Workaround, It's a Pattern
+
+The bypass with `expr()` is not a hack or workaround - it's the **correct pattern** for filter-based authorization in Ash when dealing with list queries.
+
+### 3. Scope Concept Remains Essential
+
+Even with bypass for READ, the scope concept in PermissionSets is essential for:
+- UPDATE/CREATE/DESTROY operations
+- Documentation and maintainability
+- Centralized permission management
+
+### 4. Consistency Across Resources
+
+Following the same pattern (Bypass for READ, HasPermission for UPDATE) across User and Member resources makes the codebase more maintainable and predictable.
+
+### 5. Documentation Is Key
+
+Thorough documentation explaining **WHY** the pattern exists prevents future confusion and ensures the pattern is applied correctly in future resources.
+
+---
+
+## Future Considerations
+
+### If Adding New Resources with Filter-Based Permissions
+
+Follow the same pattern:
+1. Bypass with `expr()` for READ (list queries)
+2. HasPermission for UPDATE/CREATE/DESTROY (uses scope from PermissionSets)
+3. Define appropriate scopes in PermissionSets (`:own`, `:linked`, `:all`)
+
+### If Ash Framework Changes
+
+If a future version of Ash reliably calls `auto_filter` when `strict_check` returns `:unknown`:
+1. Consider removing bypass for READ
+2. Keep only HasPermission policy
+3. Update tests to verify new behavior
+4. Update documentation
+
+**For now (Ash 3.13.1), the current pattern is correct and necessary.**
+
+---
+
+## Conclusion
+
+✅ **User Resource Authorization Policies are fully implemented, tested, and documented.**
+
+The implementation:
+- Follows best practices for Ash policies
+- Is consistent with Member resource pattern
+- Uses the scope concept from PermissionSets effectively
+- Has comprehensive test coverage
+- Is thoroughly documented for future developers
+
+**Status: PRODUCTION READY** 🎉

+### 5.1a NoActor Pattern - Test Environment Only
+
+**IMPORTANT:** The `Mv.Authorization.Checks.NoActor` check is **ONLY for test environment**. It must NEVER be used in production.
+
+**What NoActor Does:**
+
+- Allows CRUD operations without an actor in **test environment only**
+- Denies all operations without an actor in **production/dev** (fail-closed)
+- Uses both compile-time and runtime guards to prevent accidental production use
+
+**Security Guards:**
+
+```elixir
+# Compile-time guard
+@allow_no_actor_bypass Mix.env() == :test
+
+# Runtime guard (double-check)
+def match?(nil, _context, _opts) do
+  if @allow_no_actor_bypass and Mix.env() == :test do
+    true  # Only in test
+  else
+    false  # Production/dev - fail-closed
+  end
+end
+```
+
+**Why This Pattern Exists:**
+
+- Test fixtures often need to create resources without an actor
+- Production operations MUST always have an actor for security
+- The double guard (compile-time + runtime) prevents config drift
+
+**NEVER Use NoActor in Production:**
+
+```elixir
+# ❌ BAD - Don't do this in production code
+Ash.create!(Member, attrs)  # No actor - will fail in prod
+
+# ✅ GOOD - Use admin actor for system operations
+admin_user = get_admin_user()
+Ash.create!(Member, attrs, actor: admin_user)
+```
+
+**Alternative: System Actor Pattern**
+
+For production system operations, use the System Actor Pattern (see Section 3.3) instead of NoActor:
+
+```elixir
+# System operations in production
+system_actor = get_system_actor()
+Ash.create!(Member, attrs, actor: system_actor)
+```
+
+**Testing:**
+
+- NoActor tests verify both compile-time and runtime guards
+- Tests ensure NoActor returns `false` in non-test environments
+- See `test/mv/authorization/checks/no_actor_test.exs`

   3. Finds matching permission for current resource + action
   4. Applies scope filter (:own, :linked, :all)
 
+  ## Important: strict_check Behavior
+
+  For filter-based scopes (`:own`, `:linked`):
+  - **WITH record**: Evaluates filter against record (returns `true`/`false`)
+  - **WITHOUT record** (queries/lists): Returns `false`
+
+  **Why `false` instead of `:unknown`?**
+
+  Ash's policy evaluation doesn't reliably call `auto_filter` when `strict_check`
+  returns `:unknown`. To ensure list queries work correctly, resources **MUST** use
+  bypass policies with `expr()` for READ operations (see `docs/policy-bypass-vs-haspermission.md`).
+
+  This means `HasPermission` is **NOT** generically reusable for query authorization
+  with filter scopes - it requires companion bypass policies.
+
+  ## Usage Pattern
+
+  See `docs/policy-bypass-vs-haspermission.md` for the two-tier pattern:
+  - **READ**: `bypass` with `expr()` (handles auto_filter)
+  - **UPDATE/CREATE/DESTROY**: `HasPermission` (handles scope evaluation)

 ```
 
 **Why this works:**
-- Ash evaluates policies top-to-bottom
-- First matching policy wins
-- Special case catches own-account access before checking permissions
-- Even a user with `own_data` (no admin permissions) can update their credentials
+- READ bypass handles list queries correctly (auto_filter)
+- UPDATE is handled by HasPermission with `scope :own` from PermissionSets
+- All permission sets (`:own_data`, `:read_only`, `:normal_user`, `:admin`) grant `User.update :own`
+- Even a user with `read_only` (read-only for member data) can update their own credentials
+
+**Important:** UPDATE is NOT an unverrückbarer Spezialfall (hardcoded bypass). It is controlled by PermissionSets. If a permission set is changed to remove `User.update :own`, users with that set will lose the ability to update their credentials. See "User Credentials: Why read_only Can Still Update" below for details.
+
+### 1a. User Credentials: Why read_only Can Still Update
+
+**Question:** If `read_only` means "read-only", why can users with this permission set still update their own credentials?
+
+**Answer:** The `read_only` permission set refers to **member data**, NOT user credentials. All permission sets grant `User.update :own` to allow password changes and profile updates.
+
+**Implementation Details:**
+
+1. **UPDATE is controlled by PermissionSets**, not a hardcoded bypass
+2. **All 4 permission sets** (`:own_data`, `:read_only`, `:normal_user`, `:admin`) explicitly grant:
+   ```elixir
+   %{resource: "User", action: :update, scope: :own, granted: true}
+   ```
+3. **HasPermission** evaluates `scope :own` for UPDATE operations (when a changeset with record is present)
+4. **No special bypass** is needed for UPDATE - it works correctly via HasPermission
+
+**Why This Design?**
+
+- **Flexibility:** Permission sets can be modified to change UPDATE behavior
+- **Consistency:** All permissions are centralized in PermissionSets
+- **Clarity:** The name "read_only" refers to member data, not user credentials
+- **Maintainability:** Easy to see what each role can do in PermissionSets module
+
+**Warning:** If a permission set is changed to remove `User.update :own`, users with that set will **lose the ability to update their credentials**. This is intentional - UPDATE is controlled by PermissionSets, not hardcoded.
+
+**Example:**
+```elixir
+# In PermissionSets.get_permissions(:read_only)
+resources: [
+  # User: Can read/update own credentials only
+  # IMPORTANT: "read_only" refers to member data, NOT user credentials.
+  # All permission sets grant User.update :own to allow password changes.
+  %{resource: "User", action: :read, scope: :own, granted: true},
+  %{resource: "User", action: :update, scope: :own, granted: true},
+  
+  # Member: Can read all members, no modifications
+  %{resource: "Member", action: :read, scope: :all, granted: true},
+  # Note: No Member.update permission - this is the "read_only" part
+]

+  Helper functions for ensuring actors have required data loaded.
+
+  ## Actor Invariant
+
+  Authorization policies (especially HasPermission) require that the actor
+  has their `:role` relationship loaded. This module provides helpers to
+  ensure this invariant is maintained across all entry points:
+
+  - LiveView on_mount hooks
+  - Plug pipelines
+  - Background jobs

+  ## Usage

+        assign(socket, :current_user, user)
+      end
+
+      # In tests
+      user = Actor.ensure_loaded(user)
+
+  ## Security Note
+
+  `ensure_loaded/1` loads the role with `authorize?: true` (default).
+  The Role resource must have policies that allow an actor to read their own role.
+  See `Mv.Authorization.Checks.HasPermission` for the fallback implementation.

+- Use **NoActor** for test fixtures (automatic via config)

+## Authorization Bootstrap Patterns
+
+This section clarifies three different mechanisms for bypassing standard authorization, their purposes, and when to use each.
+
+### Overview
+
+The codebase uses three authorization bypass mechanisms:
+
+1. **NoActor** - Test-only bypass (compile-time secured)
+2. **system_actor** - Admin user for systemic operations
+3. **authorize?: false** - Bootstrap bypass for circular dependencies
+
+**All three are necessary and serve different purposes.**
+
+### 1. NoActor Check
+
+**Purpose:** Allows CRUD operations without actor in test environment only.
+
+**Implementation:**
+```elixir
+# lib/mv/authorization/checks/no_actor.ex
+@allow_no_actor_bypass Application.compile_env(:mv, :allow_no_actor_bypass, false)
+
+def match?(nil, _context, _opts) do
+  @allow_no_actor_bypass  # true in test.exs, false elsewhere
+end
+```
+
+**Security:**
+- Compile-time flag (not runtime `Mix.env()` check)
+- Default: false (fail-closed)
+- Only enabled in `config/test.exs`
+
+**Use Case:** Test fixtures without verbose actor setup:
+```elixir
+# With NoActor (test environment only)
+member = create_member(%{name: "Test"})
+
+# Production behavior (NoActor returns false)
+member = create_member(%{name: "Test"}, actor: user)
+```
+
+**Trade-off:** May mask tests that should fail without actor. Mitigated by explicit policy tests (e.g., `test/mv/accounts/user_policies_test.exs`).
+
+### 2. System Actor
+
+**Purpose:** Admin user for systemic operations that must always succeed regardless of user permissions.
+
+**Implementation:**
+```elixir
+system_actor = Mv.Helpers.SystemActor.get_system_actor()
+# => %User{email: "system@mila.local", role: %{permission_set_name: "admin"}}
+```
+
+**Security:**
+- No password (hashed_password = nil) → cannot login
+- No OIDC ID (oidc_id = nil) → cannot authenticate
+- Cached in Agent for performance
+- Created automatically in test environment if missing
+
+**Use Cases:**
+- **Email synchronization** (User ↔ Member email sync)
+- **Email uniqueness validation** (cross-resource checks)
+- **Cycle generation** (mandatory side effect)
+- **OIDC account linking** (user not yet logged in)
+- **Cross-resource validations** (must work regardless of actor)
+
+**Example:**
+```elixir
+def get_linked_member(%{member_id: id}) do
+  system_actor = SystemActor.get_system_actor()
+  opts = Helpers.ash_actor_opts(system_actor)
+  
+  # Email sync must work regardless of user permissions
+  Ash.get(Mv.Membership.Member, id, opts)
+end
+```
+
+**Why not `authorize?: false`?**
+- System actor is explicit (clear intent: "systemic operation")
+- Policies are evaluated (with admin rights)
+- Audit trail (actor.email = "system@mila.local")
+- Consistent authorization flow
+- Testable
+
+### 3. authorize?: false
+
+**Purpose:** Skip policies for bootstrap scenarios with circular dependencies.
+
+**Use Cases:**
+
+**1. Seeds** - No admin exists yet to use as actor:
+```elixir
+# priv/repo/seeds.exs
+Accounts.create_user!(%{email: admin_email},
+  authorize?: false  # Bootstrap: no admin exists yet
+)
+```
+
+**2. SystemActor Bootstrap** - Chicken-and-egg problem:
+```elixir
+# lib/mv/helpers/system_actor.ex
+defp find_user_by_email(email) do
+  # Need to find system actor, but loading requires system actor!
+  Mv.Accounts.User
+  |> Ash.Query.filter(email == ^email)
+  |> Ash.read_one(authorize?: false)  # Bootstrap only
+end
+```
+
+**3. Actor.ensure_loaded** - Circular dependency:
+```elixir
+# lib/mv/authorization/actor.ex
+defp load_role(actor) do
+  # Actor needs role for authorization,
+  # but loading role requires authorization!
+  Ash.load(actor, :role, authorize?: false)  # Bootstrap only
+end
+```
+
+**4. assign_default_role** - User creation:
+```elixir
+# User doesn't have actor during creation
+Mv.Authorization.Role
+|> Ash.Query.filter(name == "Mitglied")
+|> Ash.read_one(authorize?: false)  # Bootstrap only
+```
+
+**Security:**
+- Very powerful - skips ALL policies
+- Use sparingly and document every usage
+- Only for bootstrap scenarios
+- All current usages are legitimate
+
+### Comparison
+
+| Aspect | NoActor | system_actor | authorize?: false |
+|--------|---------|--------------|-------------------|
+| **Environment** | Test only | All | All |
+| **Actor** | nil | Admin user | nil |
+| **Policies** | Bypassed | Evaluated | Skipped |
+| **Audit Trail** | No | Yes (system@mila.local) | No |
+| **Use Case** | Test fixtures | Systemic operations | Bootstrap |
+| **Explicit?** | Policy bypass | Function call | Query option |
+
+### Decision Guide
+
+**Use NoActor when:**
+- ✅ Writing test fixtures
+- ✅ Compile-time guard ensures test-only
+
+**Use system_actor when:**
+- ✅ Systemic operation must always succeed
+- ✅ Email synchronization
+- ✅ Cycle generation
+- ✅ Cross-resource validations
+- ✅ OIDC flows (user not logged in)
+
+**Use authorize?: false when:**
+- ✅ Bootstrap scenario (seeds)
+- ✅ Circular dependency (SystemActor bootstrap, Actor.ensure_loaded)
+- ⚠️ Document with comment explaining why
+
+**DON'T:**
+- ❌ Use `authorize?: false` for user-initiated actions
+- ❌ Use `authorize?: false` when `system_actor` would work
+- ❌ Enable NoActor outside test environment
+
+### The Circular Dependency Problem
+
+**SystemActor Bootstrap:**
+```
+SystemActor.get_system_actor()
+  ↓ calls find_user_by_email()
+  ↓ needs to query User
+  ↓ User policies require actor
+  ↓ but we're loading the actor!
+  
+Solution: authorize?: false for bootstrap query
+```
+
+**Actor.ensure_loaded:**
+```
+Authorization check (HasPermission)
+  ↓ needs actor.role.permission_set_name
+  ↓ but role is %Ash.NotLoaded{}
+  ↓ load role with Ash.load(actor, :role)
+  ↓ but loading requires authorization
+  ↓ which needs actor.role!
+  
+Solution: authorize?: false for role load
+```
+
+**Why this is safe:**
+- Actor is loading their OWN data (role relationship)
+- Actor already passed authentication boundary
+- Role contains no sensitive data (just permission_set reference)
+- Alternative (denormalize permission_set_name) adds complexity
+
+### Examples
+
+**Good - system_actor for systemic operation:**
+```elixir
+defp check_if_email_used(email) do
+  system_actor = SystemActor.get_system_actor()
+  opts = Helpers.ash_actor_opts(system_actor)
+  
+  # Validation must work regardless of current actor
+  Ash.read(User, opts)
+end
+```
+
+**Good - authorize?: false for bootstrap:**
+```elixir
+# Seeds - no admin exists yet
+Accounts.create_user!(%{email: admin_email}, authorize?: false)
+```
+
+**Bad - authorize?: false for user action:**
+```elixir
+# WRONG: Bypasses all policies for user-initiated action
+def delete_member(member) do
+  Ash.destroy(member, authorize?: false)  # ❌ Don't do this!
+end
+
+# CORRECT: Use actor
+def delete_member(member, actor) do
+  Ash.destroy(member, actor: actor)  # ✅ Policies enforced
+end
+```
