Willgnner Santos focused on repository hygiene for the Willgnner-Santos/Fatesg-IA-2 project, addressing issues caused by unintended scaffolding and asset additions in the Big-Data, Banco-NoSQL, and PI directories. Using version control best practices, Willgnner reverted unnecessary files such as PNGs, README documents, and an empty .gitkeep, restoring the intended directory structure and improving traceability. The work, primarily involving Markdown and Git, stabilized the codebase by reducing build noise and preventing scope drift. This targeted bug fix established a clean baseline for future development, demonstrating careful attention to project scope and risk mitigation within a short one-month period.
