model: behavior ~ stim + day + stim:day + (1|rat)   (behavior = success RATE; day within-window)
observed groups: stim n=4, control n=2   nrep=120, alpha=0.05
ground truth: stim:day=+0.0102/day, rat SD=0.03828, residual SD=0.05632, days=5

 true stim:day interaction = +0.0102 (100% of observed)

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