Subject: [PATCH 001/112] feat: add CheckPagePermission plug for page-level
 authorization

- Plug checks PermissionSets page list; redirects unauthorized to profile or sign-in.
- Router: add plug to :browser pipeline; LiveHelpers: check_page_permission_on_params
  for client-side navigation (push_patch).

+defmodule MvWeb.Plugs.CheckPagePermission do

+  Plug that checks if the current user has permission to access the requested page.
+
+  Runs in the router pipeline before LiveView mounts. Uses PermissionSets page list
+  and matches the current route template (or request path) against allowed patterns.
+
+  ## How It Works
+
+  1. Public paths (e.g. /auth, /register) are exempt and pass through.
+  2. Extracts page path from conn via `Phoenix.Router.route_info/4` (route template
+     like "/members/:id") or falls back to `conn.request_path`.
+  3. Gets current user from `conn.assigns[:current_user]`.
+  4. Gets user's permission_set_name from role and calls `PermissionSets.get_permissions/1`.
+  5. Matches requested path against allowed patterns (exact, dynamic `:param`, wildcard "*").
+  6. If unauthorized: redirects to "/sign-in" (no user) or "/users/:id" (user profile) with flash error and halts.
+
+  ## Pattern Matching
+
+  - Exact: "/members" == "/members"
+  - Dynamic: "/members/:id" matches "/members/123"
+  - Wildcard: "*" matches everything (admin)
+  - Reserved: the segment "new" is never matched by `:id` or `:slug` (e.g. `/members/new` and `/groups/new` require an explicit page permission).

Subject: [PATCH 003/112] test: add page permission tests and ConnCase role
 tags

- ConnCase: add :read_only and :normal_user role tags for tests.
- Add CheckPagePermission plug tests (unit + integration for member, read_only,
  normal_user, admin). Update permission_sets_test (refute "/" for own_data).
- Profile navigation, global_settings, role_live, membership_fee_type: use
  users with role for "/" access; expect redirect for own_data on /settings
  and /admin/roles.

Subject: [PATCH 004/112] fix: handle nil member in MembershipFeeHelpers

- get_last_completed_cycle/2 and get_current_cycle/2 return nil when member is nil.
- Avoids FunctionClauseError when MemberLive.Show receives no member (e.g. after
  redirect or policy filter). Add unit tests for nil member.

+# Page Permission – Route and Test Coverage
+
+This document lists all protected routes, which permission set may access them, and how they are covered by tests.
+
+## Protected Routes (Router scope with CheckPagePermission in :browser)
+
+| Route | own_data | read_only | normal_user | admin |
+|-------|----------|-----------|-------------|-------|
+| `/` | ✗ | ✓ | ✓ | ✓ |
+| `/members` | ✗ | ✓ | ✓ | ✓ |
+| `/members/new` | ✗ | ✗ | ✓ | ✓ |
+| `/members/:id` | ✓ (linked only) | ✓ | ✓ | ✓ |
+| `/members/:id/edit` | ✗ | ✗ | ✓ | ✓ |
+| `/members/:id/show/edit` | ✗ | ✗ | ✓ | ✓ |
+| `/users` | ✗ | ✗ | ✗ | ✓ |
+| `/users/new` | ✗ | ✗ | ✗ | ✓ |
+| `/users/:id` | ✓ (own only) | ✗ | ✗ | ✓ |
+| `/users/:id/edit` | ✗ | ✗ | ✗ | ✓ |
+| `/users/:id/show/edit` | ✗ | ✗ | ✗ | ✓ |
+| `/settings` | ✗ | ✗ | ✗ | ✓ |
+| `/membership_fee_settings` | ✗ | ✗ | ✗ | ✓ |
+| `/membership_fee_types` | ✗ | ✗ | ✗ | ✓ |
+| `/membership_fee_types/new` | ✗ | ✗ | ✗ | ✓ |
+| `/membership_fee_types/:id/edit` | ✗ | ✗ | ✗ | ✓ |
+| `/groups` | ✗ | ✓ | ✓ | ✓ |
+| `/groups/new` | ✗ | ✗ | ✗ | ✓ |
+| `/groups/:slug` | ✗ | ✓ | ✓ | ✓ |
+| `/groups/:slug/edit` | ✗ | ✗ | ✗ | ✓ |
+| `/admin/roles` | ✗ | ✗ | ✗ | ✓ |
+| `/admin/roles/new` | ✗ | ✗ | ✗ | ✓ |
+| `/admin/roles/:id` | ✗ | ✗ | ✗ | ✓ |
+| `/admin/roles/:id/edit` | ✗ | ✗ | ✗ | ✓ |
+
+**Note:** Permission sets define `/custom_field_values` and related paths, but there are no such routes in the router; those entries are for future use.
+
+## Public Paths (no permission check)
+
+- `/auth*`, `/register`, `/reset`, `/sign-in`, `/sign-out`, `/confirm*`, `/password-reset*`, `/set_locale`
+
+## Test Coverage
+
+**File:** `test/mv_web/plugs/check_page_permission_test.exs`
+
+### Unit tests (plug called directly with mock conn)
+
+- Static: own_data denied `/members`; read_only allowed `/members`; flash on denial.
+- Dynamic: read_only allowed `/members/123`; normal_user allowed `/members/456/edit`; read_only denied `/members/123/edit`.
+- read_only / normal_user: denied `/admin/roles`; read_only denied `/members/new`.
+- Wildcard: admin allowed `/admin/roles`, `/members/999/edit`.
+- Unauthenticated: nil user denied, redirect `/sign-in`.
+- Public: unauthenticated allowed `/auth/sign-in`, `/register`.
+- Error: no role, invalid permission_set_name → denied.
+
+### Integration tests (full router, Mitglied = own_data)
+
+**Denied (Mitglied gets 302 → `/users/:id`):**
+
+- `/members`, `/members/new`, `/users`, `/users/new`, `/settings`, `/membership_fee_settings`, `/membership_fee_types`, `/membership_fee_types/new`, `/groups`, `/groups/new`, `/admin/roles`, `/admin/roles/new`
+- `/members/:id/edit`, `/members/:id/show/edit`, `/users/:id` (other user), `/users/:id/edit` (other), `/users/:id/show/edit` (other), `/membership_fee_types/:id/edit`, `/groups/:slug`, `/admin/roles/:id`, `/admin/roles/:id/edit`
+
+**Allowed (Mitglied gets 200):**
+
+- `/users/:id` (own profile), `/users/:id/edit`, `/users/:id/show/edit`
+- `/members/:id`, `/members/:id/edit`, `/members/:id/show/edit` for linked member (plug unit tests; full-router tests for linked member skipped: session/LiveView constraints)
+
+**Root:** `GET /` redirects Mitglied to profile (root not allowed for own_data).
+
+All protected routes above are either covered by integration “denied” tests for Mitglied or by unit tests for the relevant permission set.
+
+### Integration tests (full router, read_only = Vorstand/Buchhaltung)
+
+**Allowed (200):** `/`, `/members`, `/members/:id`, `/groups`, `/groups/:slug`.
+
+**Denied (302 → `/users/:id`):** `/members/new`, `/members/:id/edit`, `/users`, `/users/new`, `/settings`, `/membership_fee_settings`, `/membership_fee_types`, `/groups/new`, `/groups/:slug/edit`, `/admin/roles`, `/admin/roles/:id`.
+
+### Integration tests (full router, normal_user = Kassenwart)
+
+**Allowed (200):** `/`, `/members`, `/members/new`, `/members/:id`, `/members/:id/edit`, `/groups`, `/groups/:slug`.
+
+**Denied (302 → `/users/:id`):** `/users`, `/users/new`, `/users/:id` (other user), `/settings`, `/membership_fee_settings`, `/membership_fee_types`, `/groups/new`, `/groups/:slug/edit`, `/admin/roles`, `/admin/roles/:id`.
+
+### Integration tests (full router, admin)
+
+**Allowed (200):** All protected routes (sample covered: `/`, `/members`, `/users`, `/settings`, `/membership_fee_settings`, `/admin/roles`, `/members/:id`, `/admin/roles/:id`, `/groups/:slug`).
+
+## Plug behaviour: reserved segments
+
+The plug treats `"new"` as a reserved path segment so that patterns like `/members/:id` and `/groups/:slug` do not match `/members/new` or `/groups/new`. Thus `/groups/new` is only allowed when the permission set explicitly lists `/groups/new` (currently only admin).

 ## Plug behaviour: reserved segments
 
 The plug treats `"new"` as a reserved path segment so that patterns like `/members/:id` and `/groups/:slug` do not match `/members/new` or `/groups/new`. Thus `/groups/new` is only allowed when the permission set explicitly lists `/groups/new` (currently only admin).
+
+## Role and member_id loading
+
+The plug may reload the user's role (and optionally `member_id`) before checking page permission. Session/`load_from_session` can leave the role unloaded; the plug uses `Mv.Authorization.Actor.ensure_loaded/1` (and, when needed, loads `member_id`) so that permission checks always have the required data. No change to session loading is required; this is documented for clarity.

 - A user cannot link themselves to an existing member
 - A user CAN create a new member and be directly linked to it (self-service)
 
+**Enforcement:** The User resource restricts the `update_user` action (which accepts the `member` argument for link/unlink) to admins only via `Mv.Authorization.Checks.ActorIsAdmin`. The UserLive.Form shows the Member-Linking UI and runs member link/unlink on save only when the current user is admin; non-admins use the `:update` action (email only) for profile edit.

 ### Approach: Separate Ash Actions
 
 We use **different Ash actions** to enforce different policies:

-- [ ] Update CSV templates documentation to explain custom field columns (pending Issue #1)
+- [x] Update CSV templates documentation to explain custom field columns (documented in Issue #1)
 - [x] Add tests for custom field import (valid, invalid name, type validation, warning for unknown)
 
 **Definition of Done:**
 - [x] Custom field columns are recognized by name (with normalization)
 - [x] Warning messages shown for unknown custom field columns (import continues)
 - [x] Custom field values are created and linked to members
-- [x] Type validation works for all custom field types
-- [ ] UI clearly explains custom field requirements (pending Issue #7)
+- [x] Type validation works for all custom field types (string, integer, boolean, date, email)
+- [x] UI clearly explains custom field requirements (completed in Issue #7)
 - [x] Tests cover custom field import scenarios (including warning for unknown names)
+- [x] Error messages include custom field validation errors with proper formatting
 
 **Implementation Notes:**
 - Custom field lookup is built in `prepare/2` and passed via `custom_field_lookup` in opts

-
-  The CSV import feature allows administrators to upload CSV files and import members.
-
-  ### File Upload
-
-  Files are uploaded automatically when selected (`auto_upload: true`). No manual
-  upload trigger is required.
-
-  ### Rate Limiting
-
-  Currently, there is no rate limiting for CSV imports. Administrators can start
-  multiple imports in quick succession. This is intentional for bulk data migration
-  scenarios, but should be monitored in production.
-
-  ### Limits
-
-  - Maximum file size: configurable via `config :mv, csv_import: [max_file_size_mb: ...]`
-  - Maximum rows: configurable via `config :mv, csv_import: [max_rows: ...]` (excluding header)
-  - Processing: chunks of 200 rows
-  - Errors: capped at 50 per import

   Settings is a singleton resource - there is only one settings record.
   The club_name can also be set via the `ASSOCIATION_NAME` environment variable.

+  LiveView for importing and exporting members via CSV.
+
+  ## Features
+  - CSV member import (admin only)
+  - Real-time import progress tracking
+  - Error and warning reporting
+  - Custom fields support
+
+  ## CSV Import
+
+  The CSV import feature allows administrators to upload CSV files and import members.
+
+  ### File Upload
+
+  Files are uploaded automatically when selected (`auto_upload: true`). No manual
+  upload trigger is required.
+
+  ### Rate Limiting
+
+  Currently, there is no rate limiting for CSV imports. Administrators can start
+  multiple imports in quick succession. This is intentional for bulk data migration
+  scenarios, but should be monitored in production.
+
+  ### Limits
+
+  - Maximum file size: configurable via `config :mv, csv_import: [max_file_size_mb: ...]`
+  - Maximum rows: configurable via `config :mv, csv_import: [max_rows: ...]` (excluding header)
+  - Processing: chunks of 200 rows
+  - Errors: capped at 50 per import

Subject: [PATCH 034/112] Add Actor.permission_set_name/1 and admin?/1 for
 consistent capability checks

- Actor.permission_set_name(actor) returns role's permission set (supports nil role load).
- Actor.admin?(actor) returns true for system user or admin permission set.
- ActorIsAdmin policy check delegates to Actor.admin?/1.

 2. **DB constraints** - Prevent duplicates within same table (users.email, members.email)
 3. **Custom validations** - Prevent cross-table conflicts only for linked entities
 4. **Sync is bidirectional**: User ↔ Member (but User always wins on link)
+5. **Linked member email change** - When a member is linked, only administrators or the linked user may change that member's email (Member resource validation `EmailChangePermission`). This keeps email sync under control and prevents non-admins from changing another user's linked member email.

-### 3.3 System Actor Pattern
+### 3.3 CSV Import Configuration
+
+**CSV Import Limits:**
+
+CSV import functionality supports configurable limits to prevent resource exhaustion:
+
+```elixir
+# config/config.exs
+config :mv,
+  csv_import: [
+    max_file_size_mb: 10,  # Maximum file size in megabytes
+    max_rows: 1000          # Maximum number of data rows (excluding header)
+  ]
+```
+
+**Accessing Configuration:**
+
+Use `Mv.Config` helper functions:
+
+```elixir
+# Get max file size in bytes
+max_bytes = Mv.Config.csv_import_max_file_size_bytes()
+
+# Get max file size in megabytes
+max_mb = Mv.Config.csv_import_max_file_size_mb()
+
+# Get max rows
+max_rows = Mv.Config.csv_import_max_rows()
+```
+
+**Best Practices:**
+- Set reasonable limits based on server resources
+- Display limits to users in UI
+- Validate file size before upload
+- Process imports in chunks (default: 200 rows per chunk)
+- Cap error collection (default: 50 errors per import)
+
+### 3.4 Page-Level Authorization
+
+**CheckPagePermission Plug:**
+
+Use `MvWeb.Plugs.CheckPagePermission` for page-level authorization:
+
+```elixir
+# lib/mv_web/router.ex
+defmodule MvWeb.Router do
+  use MvWeb, :router
+  
+  # Add plug to router pipeline
+  pipeline :browser do
+    plug :accepts, ["html"]
+    plug :fetch_session
+    plug :fetch_live_flash
+    plug :put_root_layout, html: {MvWeb.Layouts, :root}
+    plug :protect_from_forgery
+    plug :put_secure_browser_headers
+    plug MvWeb.Plugs.CheckPagePermission  # Page-level authorization
+  end
+end
+```
+
+**Permission Set Route Matrix:**
+
+Routes are mapped to permission sets:
+- `own_data`: Can access `/profile` and `/members/:id` (own linked member only)
+- `read_only`: Can read all data, cannot modify
+- `normal_user`: Can read and modify most data
+- `admin`: Full access to all routes
+
+**Usage in LiveViews:**
+
+```elixir
+# Check page access before mount
+def mount(_params, _session, socket) do
+  actor = current_actor(socket)
+  
+  if MvWeb.Authorization.can_access_page?(actor, "/admin/roles") do
+    {:ok, assign(socket, :roles, load_roles(actor))}
+  else
+    {:ok, redirect(socket, to: ~p"/")}
+  end
+end
+```
+
+**Public Paths:**
+
+Public paths (login, OIDC callbacks) are excluded from permission checks automatically.

-  user permission checks, as email sync is a mandatory side effect.
+  All functions use the **system actor** for the load. Link existence
+  (linked vs not linked) is therefore determined **independently of the
+  current request actor**. This is required so that validations (e.g.
+  `EmailChangePermission`, `EmailNotUsedByOtherUser`) can correctly decide
+  "member is linked" even when the current user would not have read permission
+  on the related User. Using the request actor would otherwise allow
+  treating a linked member as unlinked and bypass the permission rule.

Subject: [PATCH 057/112] Tests: data-testid selectors, scoped delete, sidebar
 testid

Member/User auth tests use data-testid and #row-id selectors.
Sidebar auth tests assert on data-testid=sidebar-administration.
Sidebar test expects data-testid in expanded-menu-group markup.

+### User Role Assignment (Admin-Only)
+
+**Location:** `lib/accounts/user.ex` (update_user action), `lib/mv_web/live/user_live/form.ex`
+
+Only admins can change a user's role. The `update_user` action accepts `role_id`; the User form shows a role dropdown when `can?(actor, :update, Mv.Authorization.Role)`. **Last-admin validation:** If the only non-system admin tries to change their role, the change is rejected with "At least one user must keep the Admin role." (System user is excluded from the admin count.) See [User-Member Linking](#user-member-linking) for the same admin-only pattern.
+
+### Group Resource Policies
+
+**Location:** `lib/membership/group.ex`
+
+Policies use `HasPermission` for read/create/update/destroy. All permission sets can read; only admin can create, update, destroy. No bypass (scope :all only in PermissionSets).
+
+### MemberGroup Resource Policies
+
+**Location:** `lib/membership/member_group.ex`
+
+Bypass for read with `expr(member_id == ^actor(:member_id))` (own_data list); HasPermission for read (read_only/normal_user/admin :all) and create/destroy (normal_user + admin only). HasPermission applies `:linked` scope for MemberGroup (see HasPermission apply_scope).
+
+### MembershipFeeType Resource Policies
+
+**Location:** `lib/membership_fees/membership_fee_type.ex`
+
+Policies use `HasPermission` for read/create/update/destroy. All permission sets can read; only admin can create, update, destroy.
+
+### MembershipFeeCycle Resource Policies
+
+**Location:** `lib/membership_fees/membership_fee_cycle.ex`
+
+Policies use `HasPermission` for read/create/update/destroy. All can read; read_only cannot update/create/destroy; normal_user and admin can read, create, update, and destroy (including mark_as_paid and manual "Regenerate Cycles" in the member detail view; UI button is shown when `can_create_cycle`).

Subject: [PATCH 063/112] User form: persist role, member linking, Forbidden
 handling

- User resource: update_user accepts role_id, manage_relationship :member
- user_live/form: touch role_id, params_with_member_if_unchanged to avoid unlink
- Handle Forbidden in form, extract error message for display
- user_policies_test and form_test coverage

Subject: [PATCH 064/112] Member show & MembershipFees: permissions, delete
 all, regenerate, errors

- Show: handle_info :member_updated and :put_flash; Linked User only when can_access_page? /users
- MembershipFeesComponent: can_create_cycle/can_destroy_cycle/can_update_cycle; buttons gated
- Delete all cycles via Ash.destroy (policy enforced); format_error Forbidden
- Regenerate cycles for normal_user and admin (no admin-only check)
- Member form: format_error tuple for membership_fee_type_id; Select a membership fee type (no None)
- show_membership_fees_test: read_only UI and policy tests

-**Required Permissions:**
+**PermissionSets (lib/mv/authorization/permission_sets.ex):**
 
-- `MembershipFeeType.create/update/destroy` - Admin only
-- `MembershipFeeType.read` - Admin, Treasurer, Board
-- `MembershipFeeCycle.update` (status changes) - Admin, Treasurer
-- `MembershipFeeCycle.read` - Admin, Treasurer, Board, Own member
+- **MembershipFeeType:** All permission sets can read (:all); only admin has create/update/destroy (:all).
+- **MembershipFeeCycle:** All can read (:all); read_only has read only; normal_user and admin have read + create + update + destroy (:all).
+- **Manual "Regenerate Cycles" (UI):** The "Regenerate Cycles" button in the member detail view is shown to users who have MembershipFeeCycle create permission (normal_user and admin). Regeneration runs with system actor; UI access is gated by `can_create_cycle`.
 
-**Policy Patterns:**
+**Resource Policies:**
 
-- Use existing HasPermission check
-- Leverage existing roles (Admin, Kassenwart)
-- Member can read own cycles (linked via member_id)
+- **MembershipFeeType** (`lib/membership_fees/membership_fee_type.ex`): `authorizers: [Ash.Policy.Authorizer]`, single policy with `HasPermission` for read/create/update/destroy.
+- **MembershipFeeCycle** (`lib/membership_fees/membership_fee_cycle.ex`): Same pattern; update includes mark_as_paid, mark_as_suspended, mark_as_unpaid.

Subject: [PATCH 067/112] Refactor PermissionSets: define admin permissions via
 perm_all()

Use perm/3 helper for admin resource permissions (DRY). MemberGroup
keeps read/create/destroy only (no update in domain).

Subject: [PATCH 068/112] MemberLive: confirm_delete_all_cycles via
 Ash.destroy, reduce current_actor

- Delete each cycle with Ash.destroy(actor:) so policies apply; add do_delete_all_cycles/5.
- Use positive can? check; remove duplicate current_actor(socket) in change_membership_fee_type.

Subject: [PATCH 071/112] Tests: use Mv.Fixtures, fix warnings, Credo TODO
 disable

- Policy tests: use Fixtures where applicable; create_custom_field() fix in custom_field_value.

Subject: [PATCH 072/112] Docs and tests: fix CODE_GUIDELINES structure, use
 Mv.Fixtures in show_membership_fees_test

- CODE_GUIDELINES: correct custom_field/custom_field_value descriptions, add fixtures.ex to test support
- show_membership_fees_test: use Mv.Fixtures.member_fixture, remove redundant create_member helper

Subject: [PATCH 073/112] Secure regenerate_cycles: require can?(:create,
 MembershipFeeCycle) in handler

- Handler returns flash error when non-admin triggers event (e.g. DevTools).
- Test: read_only cannot create MembershipFeeCycle so handler rejects.

Subject: [PATCH 074/112] User: fix last-admin validation and forbid non-admin
 role_id change

- Last-admin only when target role is non-admin (admins may switch admin roles).
- Use Ash.Changeset.get_attribute for new role_id. Tests: admin role switch, non-admin update_user role_id forbidden.

Subject: [PATCH 089/112] Add Role resource policies (defense-in-depth)

- PermissionSets: Role read :all for own_data, read_only, normal_user; admin keeps full CRUD
- Role resource: authorizers and policies with HasPermission
- Tests: role_policies_test.exs (read all, create/update/destroy admin only)
- Fix existing tests to pass actor or authorize?: false for Role operations

Subject: [PATCH 090/112] Restrict member user link to admins (forbid policy)

Add ForbidMemberUserLinkUnlessAdmin check; forbid_if on Member create/update.
Fix member user-link tests: pass :user in params, assert via reload.

+  Policy check: forbids setting or changing the member–user link unless the actor is admin.
+
+  Used on Member create_member and update_member actions. When the `:user` argument
+  is present (linking a member to a user account), only admins may perform the action.
+  Non-admin users (e.g. normal_user / Kassenwart) can still create and update members
+  as long as they do not pass the `:user` argument.
+
+  ## Usage
+
+  In Member resource policies, add **before** the general HasPermission policy:
+
+      policy action_type([:create, :update]) do
+        forbid_if Mv.Authorization.Checks.ForbidMemberUserLinkUnlessAdmin
+        authorize_if Mv.Authorization.Checks.HasPermission
+      end
+
+  ## Behaviour
+
+  - If the action has no `:user` argument or it is nil/empty → does not forbid.
+  - If `:user` is set (e.g. `%{id: user_id}`) and actor is not admin → forbids (returns true).
+  - If actor is admin (or system actor) → does not forbid.

The UserLive.Form shows the Member-Linking UI and runs member link/unlink on save only when the current user is admin; non-admins use the `:update` action (email only) for profile edit.
+- **Member side:** Only admins may set or change the user–member link on **Member** create or update. When creating or updating a member, the `:user` argument (which links the member to a user account) is forbidden for non-admins. This is enforced by `Mv.Authorization.Checks.ForbidMemberUserLinkUnlessAdmin` in the Member resource policies (`forbid_if` before `authorize_if HasPermission`). Non-admins (e.g. normal_user / Kassenwart) can still create and update members as long as they do not pass the `:user` argument.

 - **User side:** The User resource restricts the `update_user` action (which accepts the `member` argument for link/unlink) to admins only via `Mv.Authorization.Checks.ActorIsAdmin`. The UserLive.Form shows the Member-Linking UI and runs member link/unlink on save only when the current user is admin; non-admins use the `:update` action (email only) for profile edit.
-- **Member side:** Only admins may set or change the user–member link on **Member** create or update. When creating or updating a member, the `:user` argument (which links the member to a user account) is forbidden for non-admins. This is enforced by `Mv.Authorization.Checks.ForbidMemberUserLinkUnlessAdmin` in the Member resource policies (`forbid_if` before `authorize_if HasPermission`). Non-admins (e.g. normal_user / Kassenwart) can still create and update members as long as they do not pass the `:user` argument.

-  ## Unlink via Member actions
+  ## Unlink semantics (update_member)
 
-  Unlink is intended via Member update_member: when `:user` is not provided in params,
-  manage_relationship uses `on_missing: :unrelate` and removes the link. Passing `user: nil`
-  or `user: %{}` explicitly is still "changing the link" and is forbidden for non-admins

+  Unlink is only possible by **explicitly** passing `:user` (e.g. `user: nil`), which this

-  Tests for automatic slug generation on CustomField resource.
+  Tests for CustomField slug business rules only.
 
-  This test suite verifies:
-  1. Slugs are automatically generated from the name attribute
-  2. Slugs are unique (cannot have duplicates)
-  3. Slugs are immutable (don't change when name changes)
-  4. Slugs handle various edge cases (unicode, special chars, etc.)
-  5. Slugs can be used for lookups
+  We test our business logic, not Ash/slugify implementation details:
+  - Slug is generated from name on create (one smoke test)
+  - Slug is unique (business rule)
+  - Slug is immutable (does not change when name is updated; cannot be set manually)
+  - Slug cannot be empty (rejects name with only special characters)
+
+  We do not test: slugify edge cases (umlauts, truncation, etc.) or Ash/Ecto struct/load behavior.

+# Admin Bootstrap and OIDC Role Sync
+
+## Overview
+
+- **Admin bootstrap:** In production, no seeds run. The first admin user is created/updated from environment variables in the Docker entrypoint (after migrate, before server). Password can be changed without redeploy via `bin/mv eval "Mv.Release.seed_admin()"`.
+- **OIDC role sync:** Optional mapping from OIDC groups (e.g. from Authentik profile scope) to the Admin role. Users in the configured admin group get the Admin role on registration and on each sign-in.
+
+## Admin Bootstrap (Part A)
+
+### Environment Variables
+
+- `ADMIN_EMAIL` – Email of the admin user to create/update. If unset, seed_admin/0 does nothing.
+- `ADMIN_PASSWORD` – Password for the admin user. If unset (and no file), no user is created in production.
+- `ADMIN_PASSWORD_FILE` – Path to a file containing the password (e.g. Docker secret).
+
+### Release Task
+
+- `Mv.Release.seed_admin/0` – Reads ADMIN_EMAIL and password from ADMIN_PASSWORD or ADMIN_PASSWORD_FILE. If both are set, creates or updates the user with the Admin role. Idempotent.
+
+### Entrypoint
+
+- rel/overlays/bin/docker-entrypoint.sh – After migrate, runs seed_admin(), then starts the server.
+
+### Seeds (Dev/Test)
+
+- priv/repo/seeds.exs – Uses ADMIN_PASSWORD or ADMIN_PASSWORD_FILE when set; otherwise fallback "testpassword" only in dev/test.
+
+## OIDC Role Sync (Part B)
+
+### Configuration
+
+- `OIDC_ADMIN_GROUP_NAME` – OIDC group name that maps to the Admin role. If unset, no role sync.
+- `OIDC_GROUPS_CLAIM` – JWT claim name for group list (default "groups").
+- Module: Mv.OidcRoleSyncConfig (oidc_admin_group_name/0, oidc_groups_claim/0).
+
+### Sync Logic
+
+- Mv.OidcRoleSync.apply_admin_role_from_user_info(user, user_info) – If admin group configured, sets user role to Admin or Mitglied based on user_info groups.
+
+### Where It Runs
+
+1. Registration: register_with_rauthy after_action calls OidcRoleSync.
+2. Sign-in: sign_in_with_rauthy prepare after_action calls OidcRoleSync for each user.
+
+### Internal Action
+
+- User.set_role_from_oidc_sync – Internal update (role_id only). Used by OidcRoleSync; not exposed.
+
+## See Also
+
+- .env.example – Admin and OIDC group env vars.
+- lib/mv/release.ex – seed_admin/0.
+- lib/mv/oidc_role_sync.ex – Sync implementation.
+- docs/oidc-account-linking.md – OIDC account linking.

Subject: [PATCH 106/112] Fix: load OIDC role sync config from ENV in all
 environments

OIDC_ADMIN_GROUP_NAME and OIDC_GROUPS_CLAIM were only set in prod block;
in dev admin_group was nil so role sync never ran. Move config outside
prod block so dev/test get ENV values.

Subject: [PATCH 108/112] OIDC: pass oauth_tokens to role sync; get? true for
 sign_in; return record in register

- sign_in_with_rauthy: get? true so Ash returns single user; pass oauth_tokens to OidcRoleSync.
- register_with_rauthy: pass oauth_tokens to OidcRoleSync; return {:ok, record} to preserve token.

Subject: [PATCH 110/112] Code-review follow-ups: policy, docs, seed_admin
 behaviour

- Use OidcRoleSyncContext for set_role_from_oidc_sync; document JWT peek risk.
- seed_admin without password sets Admin role on existing user (OIDC-only); update docs and test.
- Fix DE translation for 'access this page'; add get? true comment in User.

 ### Environment Variables
 
 - `ADMIN_EMAIL` – Email of the admin user to create/update. If unset, seed_admin/0 does nothing.
-- `ADMIN_PASSWORD` – Password for the admin user. If unset (and no file), no user is created in production.
+- `ADMIN_PASSWORD` – Password for the admin user. If unset (and no file), no new user is created; if a user with ADMIN_EMAIL already exists (e.g. OIDC-only), their role is set to Admin (no password change).
 - `ADMIN_PASSWORD_FILE` – Path to a file containing the password (e.g. Docker secret).
 
 ### Release Task
 
-- `Mv.Release.seed_admin/0` – Reads ADMIN_EMAIL and password from ADMIN_PASSWORD or ADMIN_PASSWORD_FILE. If both are set, creates or updates the user with the Admin role. Idempotent.
+- `Mv.Release.seed_admin/0` – Reads ADMIN_EMAIL and password from ADMIN_PASSWORD or ADMIN_PASSWORD_FILE. If both email and password are set: creates or updates the user with the Admin role. If only ADMIN_EMAIL is set: sets the Admin role on an existing user with that email (for OIDC-only admins); does not create a user. Idempotent.

Subject: [PATCH 111/112] OIDC sign-in: robust after_action for get? result,
 non-bang role sync

- sign_in_with_rauthy after_action normalizes result (nil/struct/list) to list before Enum.each.
- OidcRoleSync.do_set_role uses Ash.update and swallows errors so auth is not blocked; skip update if role already correct.
