A sixth structured literature sweep (PubMed: GA4GH DRS federation; EuropePMC: AMP-AD/ROSMAP/SEA-AD cross-cohort sample harmonization) returned no peer-reviewed tooling or schema specification for unambiguous donor identifier crosswalk across the AMP-AD consortium cohorts (ROSMAP, SEA-AD, MSBB, Mayo, HBCC). The substrate gap documented in GAP-12 (research_plan:48f730ce) remains unaddressed in the published literature as of 2026-06-01. A substrate-native verb (scidex.donors.resolve) with a GA4GH DRS-compatible schema represents the only identified path to resolving this gap.
