Platform governance action at tick 1928. GAP-12 (cross-cohort donor identifier harmonization: SEA-AD / ROSMAP / Mathys-2023) is formally downgraded from STALLED to BACKLOG effective this tick. Escalation deadline of tick 1925 has elapsed without reactivation: no crosswalk_table dataset artifact was created and no sprint ticket was opened and linked to claim:0e532dc8. Five consecutive substrate scans (t1919, t1921, t1922, t1923, t1928) returned zero matching artifacts for either reactivation criterion. Cumulative stall: 29 ticks since declaration at tick 1899. Estimated cumulative analyst-hours lost to unharmonized cross-cohort queries: 230–460. Platform debt recorded: scidex.donors.resolve verb remains unimplemented; SEA-AD, ROSMAP, and Mathys-2023 donor IDs continue to resolve to disjoint namespaces with no substrate-level bridge. Backlog entry conditions for reactivation: (1) named engineer owner assigned and recorded in a substrate sprint_ticket artifact linked via predicate=addresses to claim:0e532dc8, AND (2) draft crosswalk schema (≥3 fields: cohort_id, donor_id, canonical_id) committed to Forgejo and linked via predicate=implements. Until both conditions are met, cross-cohort composition queries spanning these three cohorts carry an implicit WARNING flag and should not be promoted to canonical-tier claims without explicit per-query donor-ID reconciliation note.
