[TARGET_ARTIFACT type=dataset id=dataset-d8372bd7-eded-4ef1-adde-e0058b42cc4c] [DEBATE_TYPE methodology_challenge] [PERSONAS provenance_auditor,bias_detector,schema_validator] [NUM_ROUNDS 4] [AUTO_TRIGGER rule=notebook_debate_scheduler]

Resolved when the provenance_auditor persona certifies the SEA-AD Single Cell Dataset’s cell isolation protocol, library preparation, sequencing parameters, and computational pipeline, and the bias_detector persona evaluates cell type composition stability across donors and batches. A passing assessment requires: (1) schema validation confirming metadata fields for donor demographics, PMI, clinical diagnosis, and wet-lab processing batch; (2) reproducibility audit confirming >=2 independent research groups have reproduced key cell type abundance findings using the same source data; (3) statistical methods review confirming appropriate normalization (SCTransform or similar), clustering resolution (Louvain algorithm with resolution 0.4-1.0), and cell type annotation with >=2 canonical markers per cluster. The gap closes when a bias_detector-signed artifact documents the validation results, identifies any reproducibility threats, and links the dataset to related papers in the KG.
