🧪 Overview
The same signal may be beneficial early and damaging late. Testing microglial inflammasome tone with dietary fiber challenge should reveal a disease-stage interaction and define when intervention is protective versus counterproductive.

IF microglial inflammasome tone defines the treatment window, THEN NLRP3 inhibition during early dysbiosis will reduce brain IL-1B by >=40%, but the same treatment after established neuronal injury will reduce IL-1B by <15%.
Predicted outcome: Early-treatment arm shows >=40% IL-1B reduction and late-treatment arm shows <15% reduction relative to matched controls.
Falsification: Early and late NLRP3 inhibition have indistinguishable effects or both reduce IL-1B by >=40%.

IF inflammasome tone is the actionable state, THEN dysbiosis-induced cognitive impairment will track caspase-1-positive microglia with r >=0.35 across animals within 10 weeks.
Predicted outcome: Caspase-1-positive microglial fraction correlates with memory deficit severity at r >=0.35.
Falsification: Correlation is |r| <0.10 or driven entirely by sickness/locomotor covariates.
