Working primarily with Lean and leveraging Git for version control, Dhyan focused on documentation and metadata management, carefully verifying data integrity and updating related references to maintain compliance and traceability. The work addressed a specific need for precise contributor information, supporting both repository maintenance and community standards. While the scope was targeted and did not involve bug fixes or new features beyond metadata, the update demonstrated attention to detail and commitment to data correctness.
