July 2025 highlights: Delivered core build hygiene, security, and reliability improvements across three repositories. Migrated dependencies from Jitpack to Azure Artifacts, standardized artifact URLs, and aligned builds with project naming conventions. Integrated Fortify tooling (Fortify client 1.4.9) and updated test dependencies (slf4j-simple), ensuring compatibility. Hardened frontend dependencies (Express-session, on-headers, Axios; included form-data) to address security advisories and improve stability. Consolidated build governance in hmcts/sptribs-dss-update-case-web by upgrading core libraries and maintaining consistency. Reconciled demo environment to production settings in hmcts/cnp-flux-config to ensure stable, production-aligned configurations. Overall impact: more reliable CI/CD, improved security posture, and clearer governance with production parity for demos.
