Summary

Changed membership cancellation from end-of-cycle termination to immediate deletion with loss of case access

Security assessment

The update modifies operational procedures for service cancellation but does not address a specific security vulnerability. While it impacts security posture by removing monitoring grace periods, there's no evidence this change fixes an existing security issue. The documentation update relates to security service management features.
