model: behavior ~ stim + day + stim:day + (1|rat)   [stim: Electrode-Box-B2=1 vs Electrode-Box-A2=0]
N = 8 rats, 109 sessions   (day raw; day 0 = paper "Day 1")
day coverage: stim(B2) 0..22, control(A2) 0..14
** WARNING: unequal day coverage -- the full-range stim:day interaction
   extrapolates the control group's line and is CONFOUNDED here (the paper's
   groups had equal coverage). See the _d0_13 fair-window and phased analyses. **
