PSIS-LOO across the ladder, as directional corroboration

Person-level GHK log-likelihoods per rung, fed to PSIS-LOO. Reported as directional corroboration only: with typical Q panels (N well below 100), differences in expected log predictive density between adjacent K have unreliable standard errors. The GHK seeds are common across rungs, so comparisons are common-random-number paired.
