January 2026: RosettaCommons/foundry repository hygiene improvements focused on reducing noise and maintenance overhead. Delivered a targeted feature: removal of stray macOS .DS_Store files and an updated .gitignore to prevent recurrence. No major user-facing features or bugs fixed this month; the emphasis was on codebase cleanliness and contributor efficiency. Impact includes cleaner diffs, faster code reviews, easier onboarding, and lower risk of macOS artifacts entering the main codebase. Skills demonstrated include Git hygiene, .gitignore best practices, and proactive repository maintenance across the team.
