Wesley Frias focused on improving repository hygiene for zanfranceschi/rinha-de-backend-2025 by implementing a targeted cleanup of test artifacts. He removed legacy log files, specifically docker-compose.logs and k6.logs, to reduce noise from previous test runs and streamline the continuous integration process. This work, carried out using Git and Docker, aimed to create a cleaner development environment and more reliable build workflows. While the scope of the contribution was narrow, it addressed a recurring maintenance issue and improved the overall reliability of the repository. The changes did not involve bug fixes but contributed to better project organization and CI efficiency.
