jiosephlee/assay-transfer-record-level-v26-bioavailability-ma-l4-intern

Oral bioavailability record-level V26 L4 V26 uses parent SMILES independently verified from the pinned reviewed canonical SMILES. Measurement value/unit display is canonical-first with atomic source fallback. Training balances transfer classes before choosing the highest available parent Morgan similarity. Evaluation membership is rebuilt from v2 gold. Rows: {'train': 161282, 'validation_ranking': 4600, 'test_ranking': 4700}
