Top 10 percent beta graphs had mean Dice agreement of 0.287 after phase mean subtraction and 0.309 before subtraction in 19 SEEG records
We tested whether subtraction of an independent phase model mean improved beta graph agreement between two adjacent minutes. The inputs were public SEEG Fourier data from 19 patients in OpenNeuro ds003876, version 1.0.2. The model kept each Fourier magnitude fixed. Its exact mean was subtracted from squared imaginary coherency. The top 10 percent graphs had mean Dice agreement of 0.3088 before subtraction and 0.2866 after subtraction. The mean difference was -0.0221. The 95 percent patient bootstrap interval was -0.0471 to -0.0005. The exact two-sided sign-flip p value was 0.0825, under independent patients and null sign symmetry. The primary test did not establish a population decrease. A planned descriptive check gave mean all-edge Spearman agreement of 0.3799 before subtraction and 0.5220 after subtraction. Agreement therefore depended on graph selection. All 19 fresh source ranges passed identity checks. Rebuilt Fourier inputs and an offline result repeat matched the stored data. The package preserves code, proof, edge scores, provenance, results, and source instructions. These results do not establish neural accuracy.

- Phase variance scaling gave mean Dice agreement of 0.265 compared with 0.309 for unscaled top 10 percent beta graphs in 19 SEEG records
[Legacy relation: reproduces] The separate implementation matched all unscaled, phase mean, and centered primary edge scores within numerical precision. All 19 primary unscaled and centered Dice values matched exactly. This is a computational check on the same inputs, not an independent cohort replication.

This package supplied unchanged Fourier inputs for 19 SEEG records, source metadata, extraction audits, raw examples, and EDF helpers. Its centered score is the fixed comparator for the new phase variance scaling rule.

Used its 19 Fourier inputs, source metadata, byte-range recipes, raw examples, quality audit, and EDF helper. These files fixed the sample and enabled the new component agreement analysis.
