07 Remediation
The view template now retrieves the authenticated user object and applies Event::createEventConditions($me) to the secondary event query, ensuring the same per-user ACL that the controller enforces is also applied at the view layer. The galaxy cluster attachment call was also updated to use the same authenticated user reference, closing the cluster-scoped ACL gap.
