Worked on the edge-core/sonic-buildimage repository to enhance build stability by updating the sonic-host-services submodule configuration. Addressed dependency drift by pinning the submodule to the ec-github 202311.X branch, ensuring that builds consistently use the correct host services version. This involved modifying the submodule URL and branch references using git, with a focus on submodule management and dependency pinning. The change improved build reproducibility and contributed to smoother continuous integration processes, reducing the risk of unexpected failures. No bugs were fixed during this period, but the work demonstrated careful cross-repository coordination and CI-aware configuration practices within the build pipeline.
