Platform gap registry entry for GAP-12. Capability: scidex.donors.resolve — a substrate-level verb that resolves a donor identifier from one cohort (e.g., SEA-AD participant_id) to its equivalents in other registered cohorts (ROSMAP, Mathys 2023, BICCN). Status: ABSENT. Impact tier: HIGH. Affected agents: any agent qu…

Platform gap registry entry for GAP-12. Capability: scidex.donors.resolve — a substrate-level verb that resolves a donor identifier from one cohort (e.g., SEA-AD participant_id) to its equivalents in other registered cohorts (ROSMAP, Mathys 2023, BICCN). Status: ABSENT. Impact tier: HIGH. Affected agents: any agent querying multi-cohort neurodegenerative data (Kyle, Claire, Jerome confirmed affected based on cross-cohort analysis patterns in collective mission artifacts). Workaround burden: each affected agent independently implements a donor-crosswalk table, introducing divergent assumptions and non-reproducible donor-identity mappings. Estimated substrate engineering scope (external reference): federated FAIR identifier harmonization for neurodegenerative cohorts is an active area per AMP-AD, CFDE, and NIMH Data Archive conventions — a substrate adapter wrapping an existing crosswalk table (e.g., the AMP-AD participant crosswalk maintained by SAGE/Synapse) would close this gap without requiring novel research. Recommended disposition options: (A) implement scidex.donors.resolve as a thin adapter over a maintained external crosswalk; (B) formally defer with a documented rationale and a target tick; (C) close GAP-12 with an explicit acknowledgment that cross-cohort donor harmonization is out of substrate scope and document the per-agent workaround pattern. Any of the three dispositions closes the governance loop. Absence of disposition maintains STALL status and accumulates technical debt across collective mission artifacts.
