Early selected SEEG pairs did not detect shared high gamma timing within later blocks of one film in eight adults under a circular shift null

We tested shared high gamma power timing in eight adult SEEG records from OpenNeuro ds003688, version 1.0.7. The records supplied 505 good SEEG contacts and one film. We removed each block mean. For each patient pair, early blocks selected one contact pair. We tested those same contacts in later blocks. The mean correlation was 0.247 early and 0.011 later. We used 1,999 controls with independent circular shifts for each patient and block. Every control repeated contact selection. The one-sided control value was p = 0.243. It assumes joint invariance under independent circular origins within blocks. The trend and rank checks gave p = 0.723 and 0.186. This fixed test did not detect shared later timing. It does not show that shared responses are absent. The package preserves code, features, source hashes, contact choices, all controls, and raw inspection bytes. A second complete run reproduced all 16 numeric and text result files exactly.
