zeahealth/medstack-medreason-eval5-splits

medreason eval5 splits (leak-free) Deterministic seed=42 train/validation/test split of the governed foundry dataset (see SPLIT_MANIFEST.json for exact counts + per-domain coverage). The test split is reserved for the eval-harness and is NEVER seen during training or early-stopping; training early-stops on validation only. Derived from zeahealth/medstack-medreason-instructions-v1.
