Jun 1, 2025June 2025 (hafs-community/HAFS): Stability-focused bug fix delivered to the JHAFS_OCN_PREP script. Corrected the environment variable sourcing order to ensure HOLDVARS is set before accessing ocean_model, preventing potential runtime errors during initialization. This reduces startup risk, improves reliability of the OCN preparation stage, and enhances maintainability through a clear, well-documented commit.
