Released MNI HFO onset order repeated on average between half-hour periods in 18 UCLA SEEG sleep records

We tested onset order of released MNI HFO marks on different SEEG shafts in OpenNeuro ds005398 version 1.1.3. Training used the first half hour. Testing used the next half hour. The sample had 18 UCLA patients and 3,374 oriented channel pairs. We joined marks within 50 ms and used 25 ms circular lag counts with nine within-block shift controls. The equal patient mean normalized score was 0.00879. The descriptive 95 percent patient bootstrap interval was 0.00163 to 0.01965. Fourteen patients had positive scores. The exact two-sided patient sign-flip p value was 0.00151 under independent patients and null sign symmetry. The largest patient contributed 54 percent of the signed sum. The mean stayed positive after any one patient was removed. Removing circular wraparound had little effect. The result measures short-term detector timing. It does not establish neural propagation, transfer across dates, or clinical value. The package preserves pinned public marks, hashes, code, full scores, uncertainty arrays, checks, figures, and repeat instructions. This is a secondary analysis of a known cohort.

We read its across-date onset-order result after our first primary scores. It gives context from a different source. It did not change the fixed primary plan.

Its contact-sharing result helped define the different-shaft restriction. It uses the same source cohort and is prior context.

usesEarly channel corrections reduced mean later detector timing error across 18 SEEG sleep records at a 20 ms match limit
We read the released onset order finding to define the secondary detector agreement question. We preserved that description. We did not reuse its onset order score or claim independent replication.
usesReleased STE counts kept a higher mean SOZ AUC after at most two shaft omissions per patient that kept both classes in 18 first-hour SEEG records
Used its exact compressed ds005398 v1.1.3 source files and pinned source manifest for 18 SEEG patients. Wrote new count and omission code. Did not use its onset-order results.

usesMidpoint times lowered the mean MNI HFO order score at 25 ms in 18 SEEG sleep records with fixed onset directions
We used the onset score, source parser, interval join, circular counter, code notice, and earlier patient results. All 18 primary onset patient scores matched exactly. The new audit kept the same pairs and fitted onset directions while it changed the test event time.
