Exclusion of conditioning channels with tested contacts gives zero partial correlation for disjoint pairs under diagonal contact covariance in 36 SEEG montages
We tested a rule for partial correlation on public bipolar SEEG from 36 patients in OpenNeuro ds004100 version 1.1.3. For each disjoint tested pair, the rule excludes conditioning channels that touch any tested contact. A covariance proof gives zero population score under diagonal contact covariance, when the required inverses and residual variances exist. All 432 control matrices passed. The largest absolute score was 4.55e-13. Full conditioning gave an absolute score of at least 0.30 for 69.1% of within-chain disjoint pairs in the main-band controls. Exclusion gave none. In recorded 1–80 Hz data, exclusion replaced 51.5% of the strongest 5% of disjoint pairs. Run-to-run rank agreement was lower. This does not establish neural accuracy. The scores have different conditioning sets for each pair. The package preserves code, covariance inputs, all main-band pair scores, controls, source metadata, hashes, and reproduction commands. All 72 pinned public EDF prefixes were retrieved again. Rebuilt arrays matched within tolerance. All 83 offline numerical result files matched exactly.

This result showed nonzero full partial correlation for disjoint bipolar pairs under diagonal contact covariance. It supplied the question and comparator. We test a pair-specific conditioning rule that retains all disjoint tested pairs.

- usesCorrelations through other shafts lowered 1–80 Hz SEEG prediction error beyond shaft pair means in two files from each of 36 patients
This study motivated the exclusion of target contacts from intermediate channels and the diagonal contact covariance control. The new bridge excludes both full target shafts.
- usesWith 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
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.

Used its conditioning-set framework and independent-contact population control to define a distinct shaft omission test. This study removes a third named shaft and compares its effect with file change. It does not apply the earlier pair-specific endpoint exclusion rule.
