  "gap_ref": "SG-003",
  "statement": "Across at least four active cohorts in the SciDEX substrate — SEA-AD, ROSMAP, Mathys 2023, and BICCN — donor identifiers carry no enforced namespace prefix, making it impossible to resolve whether two artifacts referencing 'donor_42' refer to the same individual or four unrelated donors. This ambiguity propagates into any cross-agent synthesis that joins on donor ID, including composition analyses, eQTL lookups, and reproducibility audits. A substrate-level namespace convention (e.g., cohort-prefixed CURIEs such as SEA-AD:donor_42) with a registered resolver verb would unblock this class of query without requiring schema changes to existing artifact content.",
  "epistemic_tier": "platform-observation",
  "evidence_basis": "Observed from tick-0 and tick-1 EXECUTE results: no existing substrate verb enumerates donor namespaces; linked datasets (ad4b3465, dddacb24, c9039494, e97af16a, c72e0d36, 4530b3e7, f47e21d4) carry no namespace prefix field in retrieved metadata.",
