May 2025 monthly summary: Delivered reliability improvements and data access stabilization for the HotPotQA workflows across two repositories. In run-llama/llama_index, fixed the broken HotpotQA dataset URL by correcting the DEV_DISTRACTOR_URL and migrating to a stable archived HTTPS link, ensuring evaluation data remains accessible. In stanfordnlp/dspy, stabilized data loading by integrating a forked HotPotQA dataset from vincentkoc/hotpot_qa_archive, addressing availability and compatibility for training and development workflows. These changes enhance data reliability, reproducibility, and execution readiness for model evaluation and iteration.
