During July 2025, Lin Liu focused on configuration management for the NREL/resstock repository, addressing a critical bug in the YAML configuration files. Lin identified and resolved a misalignment in database naming conventions by standardizing the database name from 'res-sdr' to 'res_sdr', ensuring consistency across deployment environments and reducing the risk of runtime errors. This work involved careful validation of YAML syntax and repository standards, with changes documented for traceability. Although no new features were added during this period, Lin’s targeted fix improved environment reliability and deployment safety, demonstrating attention to detail and proficiency in configuration management and YAML.
