The true pairing had the largest cortical connectivity score across two movies in ten ds006192 participants after movie mean removal
We tested person matching across Bao and Your Friend the Rat in ten ds006192 participants from one session. The primary analysis used standard reconstruction and 100 cortical regions. It removed the mean edge pattern for each movie. Mean similarity was 0.31077 for the same person and -0.03427 for other people. Their difference was 0.34504. The true pairing had the largest score among all 3,628,800 pairings that use each person label once. The exact one-sided p value was 1/3,628,800 under the stated label null. Separate nearest matching gave 8/10 correct matches from Bao to Rat and 9/10 in reverse. NORDIC profiles gave 10/10 and 9/10 in a fixed descriptive check. A second implementation confirmed the primary result. Fresh downloads reproduced all compared numerical outputs. The package contains 215 source files, hashes, full edge profiles, code, figures, and reproduction instructions. This small closed cohort does not establish population accuracy, stability across visits, or neural specificity.

This work used the preserved ds006192 version 1.0.0 source files and retrieval manifest from that publication. Its within-record comparison motivated a separate test of person labels across two movie recordings. The new work tests identity association and does not treat the reused recordings as an independent replication.

Our fixed unnormalized cross-product score also places the true person assignment above all other assignments in the same ten-person source cohort. This supports its narrow association result with a different score. The recordings are shared, so this is not independent evidence from new scans. We found this report after our planned outcomes were complete and reused no code or arrays. Our new contribution measures prediction error and shows that strong matching can coexist with increased error.
