Matched HFO counts had lower mean later STE rank agreement than all STE counts in 18 SEEG records
We tested if agreement between two high frequency oscillation (HFO) detectors improves later channel ranks. We used 18 public stereoelectroencephalography (SEEG) sleep records from OpenNeuro ds005398 version 1.1.3. The first 30 minutes supplied scores. The next 30 minutes supplied target counts. Within each channel, STE and MNI starts were matched at most 20 ms apart. Matched counts had a mean later-STE order score of 0.7484. All early STE counts scored 0.8316. Uniform removal with the same patient event total had an expected score of 0.7782. The main matched-minus-removal difference was -0.02976. Its descriptive 95% patient bootstrap interval was [-0.05821, +0.00248]. This does not establish a population decrease or prove equal performance. The fixed later-MNI check had a positive controlled gain in all 18 patients. Its mean gain was +0.05120. That check was secondary and had no multiple-test correction. The observed sign thus depended on the target detector. Clinical benefit and true event identity were not tested. The cohort was reused. The local plan was saved before new scores, without external registration. The package preserves source bytes, public retrieval pins, code, all scores, match traces, figures, and repeat instructions. Independent parsing, graph matching, subset checks, removal simulation, and a full byte repeat passed.

We used its 20 ms one-to-one start match rule as the main event selection. We tested later channel count order against event removal, which differs from its first-hour SOZ endpoint.

We adapted its finite hypergeometric expectation for uniform event removal at a fixed patient total. The first channel is now the channel with the larger later detector count. Its MIT code notice is preserved.

- usesA fixed equal STE and MNI map mixture increased later STE prediction loss within shafts in 18 SEEG sleep records
The detector matching result informed the question of detector map transfer. Our new endpoint uses fixed probability mixtures within shafts, rather than matched event ranks. The cohort is reused.
- usesTen spread minutes gave an uncertain later STE HFO order gain in 18 SEEG records under independent, exchangeable patient sampling. Circular exposure was equal.
We reused its 94 source archives, source manifest, and retrieval code. We checked all pinned public bytes again. New code built minute counts and later order scores. No prior score table supplied a new score. The original MIT notice is retained.

This prior cross-detector matching study informed question choice before the local plan. It tested later detector ranks. PLAN_NOTES.md corrects the saved plan's incorrect description of its endpoint as clinical. The present rule and SOZ endpoint differ.
