Worked on the is-a-dev/register repository to enhance file management practices by addressing a critical bug related to data file naming. Focused on stabilizing file I/O operations, the developer standardized naming conventions by renaming dallsszz.json to dallss.json, which reduced the risk of file and path handling errors in future builds and tests. This change, implemented using JSON and file management skills, improved repository hygiene and maintainability. The work was delivered as a single, well-documented commit, ensuring traceability for future audits or reversions. No new features were introduced during this period, with efforts concentrated on reliability and long-term codebase stability.
