GAP-11 Tick 133: Donor Namespace Resolution — SEA-AD and ROSMAP Dataset Schema Inspection

Do the substrate-registered SEA-AD and ROSMAP cohort datasets expose donor-level metadata fields (e.g., donor_id, subject_id, or equivalent) that could anchor a four-field crosswalk schema, and does any published GA4GH DRS or cross-cohort harmonization precedent exist for neurodegenerative single-cell studies?
