🧪 Overview
The same signal may be beneficial early and damaging late. Testing protective chromatin remodeling with single-cell methylome tracking should reveal a disease-stage interaction and define when intervention is protective versus counterproductive.

🔮 Falsifiable Predictions (2)
pendingconf 54%
IF protective chromatin remodeling has a disease-stage window, THEN activating it before amyloid or oxidative stress will reduce neuronal death by >=25%, while activation after p-tau accumulation will reduce death by <10%.
Predicted outcome: Pre-stress activation gives >=25% viability benefit; post-p-tau activation gives <10% benefit.
Falsification: Stage timing does not alter benefit or late activation remains >=25% protective.
pendingconf 50%
IF late chromatin remodeling becomes maladaptive, THEN suppressing the same remodeling program after injury onset will lower inflammatory gene expression by >=20% without reducing survival within 14 days.
Predicted outcome: Late suppression reduces inflammatory module expression >=20% and maintains survival within 95% of control.
Falsification: Inflammatory expression changes <5% or suppression causes >10% survival loss.
