The debate highlighted this fundamental causality question that determines therapeutic strategy. The Skeptic noted methylation drift could be protective rather than harmful, but this remains empirically unresolved and is critical for validating epigenetic clock interventions.

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.

Dimension Scores
How to read this chart:
Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential.
The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength),
green shows moderate-weight factors (safety, competition), and
yellow shows supporting dimensions (data availability, reproducibility).
Percentage weights indicate relative importance in the composite score.

IF ATAC-seq accessibility separates causal from compensatory methylation states, THEN causal CpG drift loci will show concordant chromatin-accessibility change in the same cell type at >=60% of loci before neurodegeneration markers rise.
pendingconf: 0.56
Expected outcome: >=60% of nominated causal CpG loci have matched ATAC-seq accessibility shifts in vulnerable cells at the pre-injury timepoint.
Falsified by: <25% of loci show concordant accessibility or shifts occur only after injury markers rise.
Method: Single-cell methylome plus ATAC-seq time course in human neurons/glia under neurodegenerative stress.
IF accessibility identifies compensatory states, THEN blocking chromatin opening at protective loci will worsen stress-induced neuronal survival by >=20% within 21 days.
pendingconf: 0.50
Expected outcome: Perturbing protective-accessibility loci lowers neuronal survival by >=20% versus non-targeting controls under stress.
Falsified by: Survival changes by <5% despite validated accessibility blockade.
Method: CRISPRi/epigenome-editing perturbation of ATAC-defined loci in stressed human iPSC neurons over 21 days.
