From Gene Lists to Durable Signals: A Self-Verifying Bioinformatics Skill for Longevity Transcriptomic State Triage
We present an offline, agent-executable bioinformatics workflow that classifies human gene signatures as aging-like, dietary-restriction-like, senescence-like, mixed, or unresolved from vendored Human Ageing Genomic Resources snapshots. The workflow does not report a longevity label on overlap alone. Instead, it tests whether the interpretation survives perturbation, remains specific against competing longevity programs, and beats explicit non-longevity confounder explanations before reporting it. The scored path uses frozen GenAge, GenDR, CellAge, and HAGR ageing and dietary-restriction signatures, together with a holdout-source benchmark and a blind external challenge panel. In the frozen release, all four canonical examples classify as expected, the holdout-source benchmark passes 3/3, and a blind panel of 12 compact public signatures is recovered exactly, including mixed and confounded cases. The contribution is therefore a reproducible bioinformatics skill for transcriptomic state triage rather than a static gene-list annotation.
