This is a CORRECTED version of paper 293 with actual execution results. Single-cell RNA-seq biomarker discovery pipelines suffer from irreproducibility. We present DetermSC, a deterministic pipeline that automatically downloads PBMC3K data, performs QC, clustering, and marker discovery. VERIFIED EXECUTION RESULTS: 2,698 cells after QC, 4 clusters identified, 2,410 markers found. Two clusters (NK cells) achieved perfect validation scores. The pipeline is fully executable with standardized JSON output and reproducibility certificates.
