## Summary by cubic
Adds a new PBAC “editUsers” permission and read gating for Attributes, updating the UI and backend so users can view and edit attributes only when allowed.
- **New Features**
- Added CustomAction.EditUsers to the permission registry for organization-scoped attribute editing.
- Settings computes canViewAttributes and shows the Attributes tab only when allowed.
- Members page fetches Attributes permissions and exposes canViewAttributes and canEditAttributesForUser to the UI.
- User Edit Sheet hides attributes without read permission and shows attribute editing and the bulk “Mass Assign Attributes” action only with editUsers; other user edits depend on changeMemberRole.
- Attributes TRPC router gates create/edit/delete/toggle via PBAC and requires organization.attributes.editUsers for assign/bulk-assign; added a helper to create PBAC-aware procedures.
- **Migration**
- Run the new Prisma migration to seed the admin role with editUsers.
- If using custom roles, grant Edit Users under Attributes as needed.
