Mar 1, 2025March 2025: Delivered a critical bug fix for the Forecast Prediction Cold Start Initialization in the global-workflow repository. Replaced dependence on the 'warm_start' flag with explicit initialization when DOIAU is set to YES, and updated the CI configuration path to support robust cold-start validation. The change reduces startup failures and ensures accurate forecast initialization, improving downstream model reliability. Demonstrated proficiency in Python scripting, version control, and CI/configuration updates across TerrenceMcGuinness-NOAA/global-workflow. Commit: 52504cd7a6130f76d1480ca2822067d288634423.
