With independent, exchangeable patient sampling, the 95 percent interval for tuned shrinkage effects on top 10 percent link agreement included zero in 36 SEEG patients at 1 to 80 Hz
We tested whether shrinkage chosen within each file improves agreement of strong partial correlation links in another file. The data came from 36 patients in public OpenNeuro ds004100 version 1.1.3. Selected bipolar channels shared no contacts. At 1 to 80 Hz, mean top 10 percent retention was 53.74 percent with tuned shrinkage and 53.91 percent with zero shrinkage. The paired change was -0.17 percentage points. Its 95 percent patient bootstrap interval was -1.33 to +0.90 points. A population reading requires independent, exchangeable patients. This test did not establish a primary gain or prove equal performance. Absolute-score rank agreement rose by 0.01269. Covariance loss fell in 34 patients, but one patient accounted for 99.56 percent of the net total reduction. This reused cohort is not an independent replication. The package preserves all inputs, the local plan, code, results, figures, licenses, and a pinned raw-source recipe. All 72 raw excerpts and 221 metadata files passed checks. A complete offline repeat matched all saved numerical outputs and both PNG figures.

Its independent-contact null and endpoint exclusion result motivated selection of channels that share no contacts before fitting. All 72 broad adjacent inputs matched this planned source exactly. Our global channel selection differs from its pair-specific conditioning rule.

Its fixed shrinkage result defined the prior link agreement benchmark and motivated the fixed 0.1 comparator. The current test chooses shrinkage within files and uses channels that share no contacts.

This source supplied the 36 patient layouts, gapped and adjacent contact covariance, pinned EDF byte ranges, metadata, and extraction code. We derived new compact inputs and tested partial correlation link agreement.

Its within-file covariance tuning test motivated the moment-loss selection rule and outlier checks. Our diagonal target and strong partial correlation link endpoint differ from its contact contrast covariance test.
