Oct 1, 2025

October 2025 monthly summary focusing on policy-related development across intel/MigTD and microsoft/MigTD. Key features delivered include Policy V2 CI test coverage in intel/MigTD, enabling the policy_v2 feature in the policy crate to validate new policy features in CI, and Policy V2 CI testing integration in microsoft/MigTD to ensure automatic validation of new policy versions. Major bugs fixed include test policy file metadata/config issues in both repos, addressed with no code changes, improving CI reliability and test discovery. Overall impact includes stronger end-to-end validation of policy changes, faster feedback loops, reduced release risk, and improved confidence in CI results. Technologies/skills demonstrated include CI/CD automation, feature flag usage (policy_v2), test design for policy validation, metadata/config management, and cross-repo collaboration.
