Add variation_logpower.m (self-contained) + make_variation_logpower.m, dropping logpowersim.m + logpower_result.txt into all 28 variation folders. Matches the paper's power code: models behavior ~ stim + log(day) + stim:log(day) + (1|rat) (log(day+1), since our day 0 = paper Day 1), reports Cohen's f (partial eta^2 of the interaction) and the interaction under residual/Satterthwaite/honest random-slope DF, then runs the Monte-Carlo power sim on the log-day ground truth (per-animal cluster-honest + LME power). Notable: under log(day) the accumulating divergence is captured more sharply, so several full-window scenarios reach honest significance that were n.s. under raw day (e.g. right_only_d0_13 honest p=0.003, unmerge_d0_13 0.021, unmerge_d0_10 0.036); Cohen's f is small-medium (~0.10-0.34).

LOG-DAY MODEL + COHEN'S f + POWER -- boxa_b2_d0_10

==============================================================================

model: behavior ~ stim + log(day) + stim:log(day) + (1|rat) (success COUNT)
|

log(day) uses 1-indexed training day (our day 0 = paper "Day 1")

|
observed groups: stim n=4, control n=3 nrep=120, alpha=0.05

--- fitted on real data ---
|

stim x log(day) interaction: F(1,68)=5.859 p(resid)=0.01817 p(Satt)=0.0182 (df=67)
|
|
honest per-animal random slope (log-day): F(1,21.8)=5.17 p=0.03322
|
|
Cohen's f (interaction, partial eta^2=0.013) = 0.115 (small-medium; f: .10 small, .25 medium, .40 large)

Read the per-animal column as the honest power; the LME column matches the
|
|
paper's power code (anova interaction p, observation-level DF) and is optimistic.
