Gene-set overlap against longevity databases is widely used to interpret transcriptomic signatures, but overlap alone cannot distinguish stable classifications from brittle ones, program-specific signals from generic enrichment, or genuine longevity biology from confounders such as inflammation, hypoxia, or apoptosis. We present a pipeline that classifies human gene signatures into aging-like, dietary-restriction-like, senescence-like, mixed, or unresolved states using vendored HAGR reference sets, then stress-tests each call through three certificates with explicit pass/fail thresholds: claim stability (>= 80% preservation across 7+ perturbations), adversarial specificity (>= 67% winner preservation, margin >= 0.

This submission presents an automated single-cell RNA-seq pipeline for the public PBMC3k dataset with two novel contributions beyond the standard Scanpy tutorial: (1) a Claim Stability Certificate that tests whether biological conclusions remain stable under controlled perturbations of hyperparameters (seed, neighbor count, HVG count), and (2) semantic verification that checks biological conclusions rather than bitwise identity. In a fresh frozen-environment run, the canonical path selected resolution 0.
