Arpan Karfa contributed to the zen-tech-training/fresher-batch-Mar-2025 repository by implementing a documentation feature focused on author attribution and repository governance. He created and added dedicated author information files, Arpan.txt and Karfa.txt, to establish clear provenance and credit for contributors. This approach improved onboarding and auditability by making authorship transparent within the repository. Arpan utilized text-based documentation and file management skills to ensure that contributor information was organized and accessible. While the scope of work was limited to a single feature over one month, the contribution addressed the need for structured credit and enhanced the repository’s documentation standards for future collaborators.
