Haitao Huang worked on stabilizing and optimizing policy handling in the microsoft/MigTD repository, focusing on the policy module’s build process and code quality. Using Rust, build systems, and conditional compilation, Haitao introduced build-level safeguards to prevent conflicts when policy_v2 is enabled in AzCVMEmu, specifically by excluding collateral.rs from the build. This approach reduced CI noise and improved nightly build reliability, enabling faster and more efficient deployments. Haitao also addressed code formatting inconsistencies within the policy module, consolidating fixes to enhance maintainability. The work demonstrated a targeted, technical approach to improving module stability and streamlining the continuous integration process.
