Row-count Bonferroni tests rejected all 40,000 null families under independent phases and fixed spectra from 20 ds006192 movie runs
We tested all 4,950 cortical pairs together in 20 processed movie runs from OpenNeuro ds006192 v1.0.0. We fixed each centered Fourier magnitude and drew independent phases. Row-count Pearson tests with Bonferroni correction rejected all 40,000 evaluation families at a 5 percent family target. Both joint maximum rules rejected 5.09 percent. We give a complete-null rank proof and supply a reusable tool. The package includes 215 checked source files, pinned retrieval, code, results, independent checks, and a full fresh-source replay. These results concern fixed spectra and a complete phase model. They do not estimate false neural connections. They do not prove strong error control in a network with real links.

The prior pair audit supplied the 20-run selection, 100 cortical labels, preserved source package, table readers, and exact fixed-spectrum variance argument. We extended it to all 4,950 pairs together and measured family rejection under shared region phase draws.
