Dec 1, 2025December 2025 (2025-12) monthly summary for awslabs/LISA. This period focused on stabilizing metrics retrieval by addressing default handling for userGroups. The fix prevents errors when userGroups are absent, improving data reliability for user metrics retrieval and updates. Implemented in two critical code paths (get_user_metrics and update_user_metrics_by_session) and tracked under issue #622 with commit 3f0a3e50093ddbd9fd114814dd02cfce113fba00, contributing to more trustworthy analytics and dashboards.

Jun 1, 2025June 2025 monthly summary for awslabs/LISA: Delivered security, reliability, and UI responsiveness improvements. Implemented EC2 Docker bucket server access logging by provisioning a dedicated log bucket (SSM parameter) and configuring the main Docker bucket to emit logs to it, enabling enhanced auditability and security monitoring. Fixed Chat Component Authentication Dependency to correctly reflect authentication state, triggering appropriate re-renders and logic updates on auth changes. Corrected NAG finding counts to ensure accurate reporting for LisaModels, improving data integrity and decision-making. These changes reinforce security visibility, user experience, and reporting accuracy, leveraging AWS services and React UI patterns to deliver business value.
