Developed a MESA Stellar Evolution Output Reader for the astropy/astropy repository, enabling direct ingestion of MESA history and profile files into analysis pipelines. The solution, implemented in Python, featured automatic format detection, metadata extraction, and configurable handling of restart artifacts to ensure monotonic model_number sequences by default. Comprehensive tests were written to validate file and data format rejection, column name checks, and restart row removal, supporting robust behavior across MESA output variants. The developer expanded unified table I/O documentation and usage examples, addressed code quality with pre-commit and Ruff fixes, and enhanced CI and documentation workflows throughout the project.
