One hemisphere of the CMB carries about 7 percent more fluctuation power than the other (A near 0.07, multipoles to 64), seen by WMAP, confirmed unchanged by Planck, at 2.5 to 3σ, with its axis in the same sky region as the quadrupole-octupole alignment, the parity preference, and the Cold Spot. Inflation guarantees identical statistics in every direction, so the model's options are bespoke superhorizon patches or a 1-in-100 accident repurchased separately for each aligned anomaly.
Statistical isotropy is the model's load-bearing wall: the generating mechanism cannot modulate power across the sky without breaking its own consistency relations. A hemispheric gradient therefore cannot be physics within ΛCDM, only chance, and chance must be invoked again for every companion anomaly sharing the direction.
SCT's origin event was not obliged to deposit evenly. A grazing or oblique collision lays down more energy on the side of deeper interpenetration, a deposition gradient across the overlap volume that thermalization smooths but does not erase (P44, P30), and the fluctuation power inherited from the cascade's stages carries that gradient as a hemispheric modulation, fixed in direction by the collision geometry (P48). The registered quantitative treatment derives the amplitude: A_hem near 1.07, the observed 7 percent, from the same 29th-level collision event that suppresses the quadrupole to a quarter of its expected power, two anomalies priced by one event in Paper 11, From Chaos to Covariant Completeness, with the imprint premises laid out in Paper 8, From Chaos To Constructive Relativity.
The shared geography of the anomaly family is then bookkeeping rather than conspiracy: asymmetry axis, alignment axis, parity preference, and Cold Spot location all descend from one oriented deposition, which is why they cluster on the sky and why ΛCDM keeps paying chance separately for each. The sub-horizon acoustics stay perfectly standard (P29), confining the signature to the large angles where it is found.
Two working premises, one inherited geometry, and the asymmetry stops being an accident: it is the shape of how our patch was poured.
The registered kill is the correlation test: the asymmetry and the quadrupole suppression must be two faces of one event, so polarization data (LiteBIRD, CMB-S4) showing them statistically uncorrelated, or the modulation absent in polarization where chance predicts absence and physics predicts recurrence, falsifies the deposition-gradient reading. The axis family adds its blade: anomaly axes mutually inconsistent at 3σ dismantles the one-event account.
