Focused on building a robust, enterprise-grade authorization framework and stabilizing the deployment stack. Delivered modular authorization components, core RBAC concepts (roles, permissions, interfaces), and a service-oriented design. Reorganized codebase to support scalable access control, introduced CompoundHierarchyId for model-level identifiers, and established a UserService for user operations. This period also modernized the container baseline with standardized Docker base images and updated worker images, unlocked faster CLI workflows with improved waiting/retry logic, and enabled structured role management with RoleAssignmentsTable and superuser checks. Together, these changes reduce security risk, speed up CI/test cycles, and set a foundation for scalable, auditable access control across OrtServer.
