A longitudinal biomarker panel centered on ATAC-seq accessibility can distinguish harmful mechanisms from protective adaptation. The decisive experiment is to measure ATAC-seq accessibility before and after senescence stratification in stratified models.

| Prediction | Predicted | Observed | Status | Conf |
|---|---|---|---|---|
| IF ATAC-seq accessibility distinguishes pathological age-related methylation drift, THEN drift loci that predict degeneration will have >=1.4-fold accessibility gain in vulnerable neuronal nuclei befo | Pathological drift loci show >=1.4-fold ATAC accessibility increase before cell-loss gene signatures. | — no observation — | pending | 0.55 |
| IF compensatory methylation states are accessibility-silent, THEN protective drift loci will show <10% ATAC change while still associating with slower NfL rise over 24 months. | Protective drift loci have <10% accessibility change and predict >=15% slower NfL slope. | — no observation — | pending | 0.48 |
