Worked on enhancing progress tracking within the ipfs/boxo repository by introducing detailed size reporting for fetched nodes in the IPLD Merkledag component. This update improved observability of data transfer sizes, supporting more accurate capacity planning and troubleshooting. The approach involved implementing new reporting logic in Go, renaming internal structs for clearer progress tracking, and addressing naming inconsistencies to streamline maintainability. Documentation and changelog updates were provided in Markdown to ensure clarity for future contributors. Throughout the process, code quality was maintained through clean, signed-off commits, demonstrating a focus on backend development, testing, and effective use of version control systems.
