- Member update_member: on_missing :unrelate → :ignore (no unlink when :user omitted)
- Test: normal_user update linked member without :user keeps link
- Doc: unlink only explicit (user: nil), admin-only; Actor.admin?(nil) note
- Check: defense-in-depth for "user" string key
- Forbid on :user argument presence (not value) to block unlink via nil/empty
- Defensive nil actor handling; policy restricted to create/update only
- Test: Ash.load with actor; test non-admin cannot unlink via user: nil
- Docs: unlink behaviour and policy split
- groups-architecture: normal_user and admin can manage groups.
- roles-and-permissions: matrix and MembershipFeeCycle :linked for own_data.
- group_policies_test: update moduledoc.
- ActorPermissionSetIs check; bypass policy filters by member_id for own_data only.
- Admin with member_id still gets :all via HasPermission. Tests added.
- Policy tests: use Fixtures where applicable; create_custom_field() fix in custom_field_value.
- Replace unused actor with _actor, remove unused alias Accounts in policy tests.
- profile_navigation_test: disable Credo for intentional TODO comment.
- Group/MemberGroup/MembershipFeeType/MembershipFeeCycle: HasPermission policy
- normal_user: Group and MembershipFeeCycle create/update/destroy; pages /groups/new, /groups/:slug/edit
- Add policy tests for all four resources
Only admins or the linked user may change a linked member's email.
- New validation EmailChangePermission (uses Actor.admin?, Loader.get_linked_user).
- Register on Member update_member; docs and gettext.
- create_linked_member_for_user and create_unlinked_member use actor
(system_actor) directly instead of creating admin user per call
- Remove create_admin_user helper
- After destroy, verify with Ash.get(..., actor: actor) to avoid
false positive from Forbidden vs NotFound
