Sarcopenia skeletal-muscle transcriptome reproducibility audit: code and results

Code, frozen analysis records, processed sample metadata, machine-readable results, figures, and submission materials for a staged reproducibility audit of human skeletal-muscle transcriptomes in sarcopenia. The archive covers source-result reproduction, model-specification sensitivity, cross-cohort gene-level replicability, external gene-panel generalizability, and external pathway concordance. Raw transcriptome data and licensed MSigDB gene-set files are not redistributed; accession numbers and acquisition instructions are provided in the documentation.
