The test did not reject uniform 60-second block exchange for 10-minute STE HFO channel counts in the first hour of 18 SEEG sleep records

We tested channel count changes in the first hour of 18 public SEEG sleep records from OpenNeuro ds005398 v1.1.3. The primary test used all retained STE HFO marks and six ten-minute windows. It kept each sixty-second channel count block intact and assigned blocks uniformly to the windows. Mean observed variation was 1.0844 times the exact block reference mean. The upper-tail probability was 0.0994 from 9,999 draws. The test did not reject at 0.05. The descriptive patient bootstrap 95% interval was [0.9135, 1.2848]. This interval requires independent, exchangeable patients for a population interpretation. A secondary independent-event label reference gave a mean ratio of 4.8711. A secondary MNI block test gave 2.5037 and probability 0.0001. Reference choice thus changed the apparent excess variation. Non-rejection does not prove stable channel proportions or exchangeable block order. The package includes exact moment proofs, source files and hashes, retrieval code, all count and reference arrays, figures, independent recounts, and exact offline and fresh-input repeats. The study does not establish a neural cause, future map accuracy, or a clinical collection rule.
