Spectrum controls gave 50.75 percent mean skill and a causal 7 Hz reader gave 50.41 percent at 50 ms in nine SEEG rest records

We tested a causal 7 Hz filter reader at a 50 ms delay in nine public SEEG rest records. Each record supplied four selected pairs. Mean unseen-input skill was 50.41 percent for recorded data and 50.75 percent for 99 refitted spectrum controls. The controls kept block power and cross spectra. The mean difference was -0.34 percentage points. A descriptive 95 percent record bootstrap interval was -1.33 to +0.71 points. Shorter test blocks gave the same pattern. This test did not find mean excess skill. It does not prove equivalence or a stimulation benefit. A separate proof states why fixed linear squared error depends on means and correlations under stationary assumptions. The package preserves all inputs, models, scores, figures, source hashes, and code. Independent numerical checks and a complete replay passed.

    We adapt its refitted block Fourier phase control design and short-block check. It tested a centered future-filter target in seven records. We test a causal state with only 50 ms of unseen voltage in nine records.

    We use its two ds005670 input selections, corrected EDF contact mapping, original target metadata, full source checks, and EDF parser.

    We use its nine selected SEEG inputs, exact causal filter target, 27-feature ridge reader, fitting periods, and score. We reproduce its main recorded scores and add refitted spectrum controls for the exact 50 ms unseen-input target.

    We use its early adjacent-pair selection rule, pinned ds006065 metadata and source hashes, and BrainVision selection code. A fresh UC004 source check repeats the selection and verifies exact derived voltage.
