June 2026 monthly summary for repository pq-code-package/mldsa-native. Focused on improving cross-platform test reliability and client robustness. Delivered two features with explicit commit references, addressing testing on unsupported architectures and enhancing error handling in the Wycheproof client. Impact: more deterministic CI outcomes, reduced debugging time, and clearer failure reports. Technologies: HOL-Light testing framework, cross-platform testing, runtime checks, Wycheproof client, code traceability via signed-off commits.

June 2025: Strengthened cryptographic modeling reliability and security in CodeQL. Key change: restrict signature input nodes to be used only in verify mode in Model.qll, preventing incorrect usage and improving modeling accuracy. The change reduces risk of insecure configurations and supports safer default behavior across cryptographic analyses. No user-facing features were released this month; the focus was on security, correctness, and maintainability. Repositories touched: github/codeql. Commit-based traceability added for future audits.

May 2025 monthly summary focusing on feature delivery and observability improvements in the CodeQL cryptographic modeling framework. Delivered the Signature Input Modeling feature by introducing SignatureArtifactConsumer and SignatureArtifactNode to model and track signature inputs throughout verification flows, enabling improved analysis and traceability of cryptographic operations. The work includes a targeted integration into the signature verification path and was landed in github/codeql with the associated commit. This month emphasized end-to-end observability, maintainability, and business-value through safer and more auditable signature handling.
