The test did not detect a response time beta gain after training site selection in eight SEEG patients under independent symmetric null patient gains

We tested whether a response time component reduces beta profile error beyond a cue model in public OpenNeuro ds004473 version 1.0.2. The test reused 511 trials and 819 candidate pairs from eight SEEG patients. Five sites on different shafts and the ridge penalties were selected only within training. Five separate chronological test blocks used a 30-second gap. The equal patient mean gain was +0.6037 percentage points of constant template error. The 95 percent patient resample interval was -0.0938 to +1.3636 points. The two-sided sign-flip test gave 0.21875 under independent and symmetric null patient gains. The primary test did not detect a mean gain. An earlier-training check gave a positive interval on 168 test trials, but no secondary sign-flip test passed a conservative multiple-test audit. The target uses the observed trial mean and known response time. This is a retrospective profile test. The package preserves features, code, source pins, trial IDs, all choices, results, and instructions. A fresh raw rebuild reproduced every power array. Independent model and spectrum checks passed. The result does not show that response-related beta changes are absent.
