With fixed readers, mean heat contrast kept more than half its early size in 115 EEG and 19 fMRI adults; the joint drift test failed

A falling neural heat score need not lose its heat contrast. We tested one fixed joint rule in separate public human EEG and fMRI studies. It required a falling mean score and late heat contrast above half the early contrast in both modalities. A public SCI protocol preceded reserved endpoint scores. The joint rule failed, p=0.06811, because the MRI mean-shift interval included zero. The planned retention components were positive in 115 EEG and 19 MRI adults. Mean late-minus-half-early contrasts were 0.259 and 0.455 person score SD. After the joint failure, simultaneous 95% intervals over all six primary components were [0.128,0.391] and [0.135,0.774]. This is a corrected exploratory retention statement, not a replacement primary. Training-and-target person bootstraps kept both retention signs. A later fixed exploratory test in 63 adults from another MRI study also met the bound, p=0.000919. Its mean score rose. All negative people and discordant shifts remain. The result concerns mean standardized contrasts in fixed readouts and source record halves. It does not establish equal early and late responses, a common neural cause, pain specificity or clinical validity. Selected EEG rows, missing exact EEG timing, inherited MRI fits, context assumptions, small MRI training size and different tasks limit scope.

A clean offline repeat matched eight CSV files and six result JSON objects.
