The Mirror Edition proposes a two-sheeted spacetime U₁ ⊕ U₂ governed by the exact antisymmetry E (u₁, x) = –E (u₂, x) at every point x. The model requires exactly one new principle — energy antisymmetry — and derives dark energy, singularity resolution, and information preservation as automatic consequences. Black holes on U₁ correspond to virtual white holes on U₂; energy flow is mediated by Planck-scale primordial black-hole pairs acting as quantum valves. The effective cosmological constant emerges as the self-regulated mean tunnel current Λₑff = 8πG ⟨JE⟩. The cosmology is eternal, singularity-free, information-preserving, and has exactly zero total energy.
