Worked on the prometheus/node_exporter repository to enhance dependency management and build stability by upgrading the procfs module from version 0.16.0 to 0.16.1. Focused on Go module hygiene, the work included running go mod tidy and updating go.sum to ensure a clean and deterministic module graph. This targeted update reduced the risk of dependency drift and improved reproducibility for future builds, supporting ongoing code health and CI reliability. Leveraged Go and expertise in dependency management to maintain compatibility with downstream consumers, laying groundwork for smoother future development without introducing new features or addressing major bugs during the period.
