Ran Score / ALSPC-DPO public structured audit metadata and aggregate results

This record contains the open public data package for the Ran Score / ALSPC-DPO study. It includes de-identified structured audit metadata, ALSPC risk scores, adaptive preference-margin metadata, label taxonomy, aggregate split statistics, encoder baseline metrics, ALSPC-DPO test metrics, selected Optuna checkpoint information, and selected hyperparameters. The package intentionally excludes raw radiology reports, report-level identifiers, prompt-response training files, chosen/rejected DPO responses, and free-text rationales. Full SFT/DPO prompt-response files and Qwen-generated rationales are provided separately under restricted access because they contain report-level or report-derived content.
