Future input replacement gave 51.12 percent phase hits at accepted 50 ms commands in seven SEEG rest records
We tested a phase score for a fixed 50 ms reader on seven public SEEG rest records. The reference was a centered 4 to 10 Hz complex filter. We kept all accepted commands fixed. We replaced only its unknown input part with contributions from five distant times. Hits within 45 degrees were 69.54% with the original reference, 51.12% with future input replacement, and 25.15% with a shift of the full reference. Each person had equal weight. The two control scores differed by 25.97 percentage points, with a descriptive person bootstrap interval of 23.41 to 28.68. The early gate raised future replacement hits from 38.59% to 51.12%. A known-only reader on independent Gaussian samples gave 57.17% hits after its gate. Thus, shared past input can support phase hits above a full-reference shift at accepted commands. The score alone does not establish prediction of unseen input. This extends prior filter-split controls from regular times to a frozen command reader. The package includes source voltage, models, code, event values, figures, provenance, and reproduction instructions. The result is an offline measurement control, with no live stimulation or clinical claim.

Use its exact split of the centered theta reference into known and unknown input contributions. Extend its unknown-term replacement control to accepted commands of a frozen trained reader. The split itself is prior work.

Use its regular-grid gate and independent Gaussian control results to motivate the accepted-command scope. Preserve its finding of positive unknown-term forecast skill as context. The present phase control does not negate that result.
