Jan 1, 2025January 2025 Monthly Summary: Delivered substantial UI cleanups, security and reliability improvements, and feature enhancements that improve user experience and platform resilience. Notable work includes renaming PTeam to Team across UI and topics, CVSS-based topic search, and targeted UI simplifications. Security and authentication were modernized by replacing cookie-based auth with getIdToken and establishing a robust core auth flow with readiness handling and sign-out. Reliability and quality were boosted through ErrorBoundary implementations, RTK Query-based email verification, and targeted bug fixes. These efforts reduce risk, improve maintainability, and enable faster iteration with stronger security and data integrity.

Dec 1, 2024Monthly performance summary for 2024-12 (nttcom/threatconnectome). This period delivered substantive end-to-end CVSS v3 score integration across topic storage, API surface, and tests, with a renaming of threat_impact to cvss_v3_score to ensure consistent risk scoring terminology. API stability improvements and test stabilization were achieved through targeted fixes and updated tagging, reducing regressions in downstream consumers. Topic lifecycle capabilities were expanded with delete/create/edit support, and UI refinements (TopicManagementTableRow borderLeft color) coupled with cleanup of obsolete components simplified the developer and operator experience. Infrastructure and data governance were strengthened by dependency updates (notably python-multipart), a new database migration script, and broader formatting/spec compliance fixes. Additional scripting work for threat data collection and improved test naming and documentation enhanced reproducibility and data quality. Overall impact includes higher risk-scoring accuracy, more reliable APIs, streamlined topic workflows, and reduced maintenance overhead.
