Mirny's Cosmodynamics: Azimuthal Discreteness of Spiral Galaxies. A blind series of pre‑registration tests, paired zero and the lower boundary of the distribution on a sample of 53 galaxies.

The introduction of the "Smooth twin" (v13c) conveyor allowed to completely isolate the instrumental system of the disks from the physical signal of the medium. The Distribution Lower Wall (in) is a direct empirical evidence of the existence of a critical threshold for macroscopic excitation of the galactic medium (ferritic vacuum). Complete invariance of pure strength of coherent signal (vs) refutes the exclusivity of the gravitational-wave mechanism and translates the spiral branches into the status of the universal threshold relays of the Preise, controlled by the parameters of local coherence of the medium.

Great invariance of environments: Purified Delta (+0.21) proved to be the same for Grand Design and for Flocculent galaxies (p=0.99). This is the undermining of the classical theory of the Len-Shu density waves, which requires a rigid connection of morphology with the degree of development of fashion.

The lower distribution wall (0.31): The distribution of real signals does not flow smoothly into zero, but is broken as a knife. The twin falls quietly to 0.07, and the real galaxy does not. This is the experimental discovery of the lower threshold of excitation of the ferrite vacuum! The environment is either switched on (at least 30% of the rings) or the sleeves do not occur at all.
