TLS info printing bug fix and several abort-related improvements further boosted robustness. On the build, security, and authentication front, we updated Seastar in Bazel, added PLAIN authentication support for K/C and Shadow Link, and upgraded Keycloak dependencies, while keeping startup responsive by moving OIDC updates to the background. Admin utilities and logging naming were refined for consistency, and modularity was improved via net:types work and related packaging changes.

Introduced a security framework with an abstract security_service, wiring into the manager, and a dedicated migrator task to standardize ACL management across modules. Improved ACL-related surface with Describe Registry ACLs tagging support and ACL proto fixes, and enhanced API default behavior consistency. Expanded testing infrastructure for topic-related features, including explicit namespaces, mocks, and cleanup to improve stability across runs.

July 2025 (Month: 2025-07) delivered a matured cluster link capability, extensive data-model enhancements, and a strengthened testing/deployment foundation.
