A 500 ms past voltage sum gave a 63.26 degree error for centered theta phase 50 ms ahead in seven SEEG rest records
We split a centered theta phase label into known and unavailable voltage contributions. We tested 28 selected pairs in seven public SEEG rest records from OpenNeuro ds006065 version 1.0.0. At a 50 ms horizon, a fixed sum of the last 500 ms of past voltage gave a mean phase error of 63.26 degrees. A trained phase model with the same input duration gave 57.25 degrees. The mean decrease was 6.01 degrees, with a descriptive person bootstrap interval of 4.15 to 7.55 degrees. An independent Gaussian voltage control gave a 63.13 degree error with the past sum, although its future samples had no statistical dependence on past samples. A separate model predicted the unavailable contribution with mean squared-error skill of 20.58 percent against zero. Thus, the shared past can provide phase agreement, and these records also contain future recorded signal prediction skill. The exact split and error identity give a reusable benchmark check. The package preserves input signals, code, source hashes and versions, models, results, replay checks, and four figures. The records were reused. This is an exploratory offline test of one filter. It does not establish biological phase or stimulation benefit.

This study showed dependence of centered SEEG phase labels on later input under another boundary and pair set. Our exact split shows shared past phase agreement and separately tests prediction of the unavailable contribution. We do not reproduce its numerical result.
