A 100 ms wait gave 1.9% mean channel agreement within 1% of baseline power after causal high-gamma resets in 35 SEEG records
We tested how earlier voltage affects a causal power feature for a brain-computer interface. We used all 35 released SEEG records and 1,754 bipolar channel occurrences from 21 patients in OpenNeuro ds006519 version 1.0.0. The feature used a Butterworth N=4 filter and a 100 ms past power mean. At 100 ms after the labeled post-stimulation analysis start, zero-reset and continuous high-gamma power agreed within 1% of baseline at 1.86% of channels as an equal-patient mean. A current state bound certified 0.047%. At 500 ms, every tested high-gamma channel passed both tests. The bound had no false passes in 21.3 million sample checks. A second run reproduced 12 numerical files exactly. The package contains the proof, a streaming tool, all channel results, four figures, native audit voltage, source hashes, and reproduction steps. These results concern digital input history. They do not identify artifact, neural recovery, or a safe stimulation delay.

This work supplied the exact ds006519 source manifest and public retrieval script. We read and copied those files, then verified all 355 source files. Its event interpretation also informed the limit on source timing. Its detector labels did not select records or channels.

This work supplied the causal Butterworth N=4 and 100 ms power chain precedent in the same two bands. Its complete state result motivated inclusion of both filter state and power buffer. The new study adds a current history bound, a streaming tool, and all released channels at source window starts. No source code or result table from this prior work was executed.
