+# User Story
+
+As an administrator, I want a concise group policy table and focused group details, so that I can manage access without navigating cumbersome controls.
+
+# Acceptance Criteria
+
+- [x] The main Groups page lists name, Minecraft access, VPN/proxy/Tor access, and effective member count with the default group first and remaining names ordered alphabetically.
+- [x] Policy controls show their current state and require confirmation in an accessible modal before mutation.
+- [x] Selecting a group name opens a detail page with its description, policies, and effective members.
+- [x] Add group opens an accessible modal asking for name, description, Minecraft access, and VPN/proxy/Tor access.
+- [x] New-group policies default to denied and can be enabled before creation.
+- [x] Administrators manage only the display name; an internal collision-safe slug is generated automatically.
+- [x] Administrators can edit group name and description; the protected `everyone` name remains fixed while its description remains editable.
+- [x] Non-default groups can be deleted only after modal confirmation, returning all affected users to `everyone`.
+- [x] Group identity, policy, creation, and deletion mutations commit atomically with their audit events.
+- [x] Modal controls support keyboard operation, focus management, cancellation, and clear pending state.
