The stated model gave a mean repeat-minus-switch beta contrast of -0.038 dB in 776 later trials from seven SEEG patients

We tested response and arrow repetition in public OpenNeuro ds004473 version 1.0.2. The test used 776 later trials from seven patients with epilepsy. Early trials selected 188 adjacent bipolar pairs on 108 shafts. We measured 13 to 30 Hz power before each keypress, relative to the baseline before fixation. Each patient had a separate model for repeats minus switches. The model controlled for current and previous side, response times, trial position, gap, and instruction runs. The patient mean contrast was -0.038 dB. The 95 percent t interval was -0.537 to +0.461 dB. The exact two-sided sign-flip p value was 0.875 under independent patients and symmetric null contrasts. The test did not resolve a group association. It does not establish absence or equivalence. A correct response repeat also repeats the arrow. This test cannot separate their effects. One source participant had no usable response switches and was excluded by the saved rule. An independent reader reproduced 2,924 power values from 28 freshly retrieved raw ranges. All range hashes matched. A clean offline repeat matched 66 scientific files. The package preserves code, powers, source locks, trial selections, model files, raw checks, and repeat instructions.
