model: behavior ~ stim + day + stim:day + (1|rat)   (behavior = success RATE; day within-window)
observed groups: stim n=3, control n=6   nrep=120, alpha=0.05
ground truth: stim:day=-0.02201/day, rat SD=0.06153, residual SD=0.06598, days=5

 true stim:day interaction = -0.02201 (100% of observed)

Read the per-animal column as the honest power; LME is optimistic (obs-level DF).
