A mechanism is proposed where the CP violating phase relaxes in discrete steps via nucleation of membranes that discharge the magnetic dual of a 4-form flux, with bubbles colliding and percolating near the chiral symmetry breaking scale during radiation domination.
Kinetic mixing between hidden-sector fluxes and QCD's topological sector shifts the effective theta angle and produces nonzero <G tilde G>.
