+**Status:** Draft for design decisions and implementation specs. **Prio 1 (Subtasks 1–4) implemented.**

 ## 3. Step 2: Vorstand Approval
 
 - **Goal:** Board (Vorstand) can review join requests (e.g. list status "submitted") and approve or reject.
+- **Route:** **`/join_requests`** for the approval UI (list and detail). See §3.1 for full specification.
 - **Outcome of approval (admin-configurable):**
   - **Default:** Approval creates **Member only**; no User is created. An admin can link a User later if needed.
   - **Optional (configurable):** If an option is set, approval may also create a **User** (e.g. invite-to-set-password). This is **open for later**; implementation concepts will be detailed when that option is implemented.
-- **Permissions:** Approval uses the existing permission set **normal_user** (e.g. role "Kassenwart"). JoinRequest gets read and update (or dedicated approve/reject actions) for scope :all in normal_user, and the approval page (e.g. `/join_requests` or `/onboarding/join_requests`) is added to normal_user’s allowed pages.
+- **Permissions:** Approval uses the existing permission set **normal_user** (e.g. role "Kassenwart"). JoinRequest gets read and update (or dedicated approve/reject actions) for scope :all in normal_user, and **`/join_requests`** (and **`/join_requests/:id`** for detail) are added to normal_user’s allowed pages.
+
+### 3.1 Step 2 – Approval (detail)
+
+Implementation spec for Subtask 5.
+
+#### Route and pages
+
+- **List:** **`/join_requests`** – list of join requests. Filter by status (default or primary view: status `submitted`); optional view for "all" or "approved/rejected" for audit.
+- **Detail:** **`/join_requests/:id`** – single join request with all data (typed fields + `form_data`), actions Approve / Reject.
+
+#### Backend (JoinRequest)
+
+- **New actions (authenticated only):**
+  - **`approve`** (update): allowed only when status is `submitted`. Sets status `approved`, `approved_at`, `reviewed_by_user_id` (actor). Triggers promotion to Member (see Promotion below).
+  - **`reject`** (update): allowed only when status is `submitted`. Sets status `rejected`, `rejected_at`, `reviewed_by_user_id`. No reason field in MVP.
+- **Policies:** `approve` and `reject` permitted via **HasPermission** for permission set **normal_user** (read/update or explicit approve/reject on JoinRequest, scope :all). Not allowed for `actor: nil`.
+- **Domain:** Expose `list_join_requests/1` (e.g. filter by status, with actor), `approve_join_request/2` (id, actor), `reject_join_request/2` (id, actor). Read action for JoinRequest for normal_user scope :all so list/detail can load data.
+
+#### Promotion: JoinRequest → Member
+
+- **When:** On successful `approve` only (status was `submitted`).
+- **Mapping:**
+  - JoinRequest typed fields → Member: **email**, **first_name**, **last_name** copied to Member attributes.
+  - **form_data** (jsonb): keys that match `Mv.Constants.member_fields()` (atom names or string keys) → corresponding Member attributes. Keys that are custom field IDs (UUID format) → create **CustomFieldValue** records linked to the new Member.
+  - **Defaults:** e.g. `join_date` = today if not in form_data; `membership_fee_type_id` = default from settings (or first available) if not provided. Handle required Member validations (e.g. email already present from JoinRequest).
+- **Implementation:** Prefer a single Ash change (e.g. `JoinRequest.Changes.PromoteToMember`) or a domain function that builds member attributes + custom_field_values from the approved JoinRequest and calls Member `create_member` (actor: reviewer or system actor as per CODE_GUIDELINES; document choice). No User created in MVP.
+- **Atomicity:** The approve flow (get JoinRequest → update to approved → promote to Member) runs inside **`Ash.transact(JoinRequest, fn -> ... end)`** so that if Member creation fails (e.g. validation, unique constraint), the JoinRequest status is rolled back and remains consistent.
+- **Idempotency:** If approve is called again by mistake (e.g. race), either reject transition when status is already `approved` or ensure Member creation is idempotent (e.g. do not create duplicate Member for same JoinRequest).
+
+#### Permission sets and routing
+
+- **PermissionSets (normal_user):** Add JoinRequest **read** :all and **update** :all (or **approve** / **reject** if using dedicated actions). Add pages **`/join_requests`** and **`/join_requests/:id`** to the normal_user pages list.
+- **Router:** Register live routes for list and detail; add entries to **page-permission-route-coverage.md** and extend plug tests so normal_user is allowed, read_only/own_data denied.
+
+#### UI/UX (approval)
+
+- **List:** Table or card list with columns e.g. submitted_at, first_name, last_name, email, status. Primary filter or default filter: status = `submitted`. Buttons or links to open detail. Follow existing list patterns (e.g. Members/Groups): header, back link, CoreComponents table.
+- **Detail:** Show all request data (typed + form_data rendered by field). Buttons: **Approve** (primary), **Reject** (secondary). Reject in MVP: no reason field; just set status to rejected and audit fields.
+- **Accessibility and i18n:** Same standards as rest of app (labels, Gettext, keyboard, ARIA where needed).
+
+#### Tests
+
+- JoinRequest: policy tests – approve/reject allowed for normal_user (and admin), forbidden for nil/own_data/read_only.
+- Domain: approve creates one Member with correct mapped data; reject only updates status and audit fields; approve when already approved is no-op or error.
+- Page permission: normal_user can GET `/join_requests` and `/join_requests/:id`; read_only/own_data cannot.
+- Optional: LiveView smoke test – list loads, approve/reject from detail updates state.

+  Creates a join request in status :submitted (for approval UI tests).
+
+  Uses the public flow: submit_join_request then confirm_join_request with a known token.
+  Returns the JoinRequest struct so tests can use its id for approve/reject.
+
+  ## Parameters
+    - `attrs` - Optional map: :email, :first_name, :last_name, :form_data, :schema_version.
+      Defaults: unique email; confirmation_token is generated and used internally.
+
+  ## Returns
+    - JoinRequest struct with status :submitted
+
+  ## Examples
+
+      iex> request = submitted_join_request_fixture()
+      iex> request.status
+      :submitted
+
+      iex> request = submitted_join_request_fixture(%{first_name: "Jane", last_name: "Doe"})
