We propose a unified framework in which spacetime, matter fields, and quantum mechanics emerge from a discrete microscopic process: local copying of a simplicial complex with stochastic defects. We demonstrate that: (i) exponential growth of vertices yields Hubble expansion H = D0/3, (ii) the cosmological constant emerges as Λ = D02/(3c2) without fine-tuning, (iii) the Schr¨odinger equation arises in the continuum limit under diffusive scaling, (iv) the Born rule and Lindblad decoherence follow from stochastic phase averaging. The model predicts a distinct deviation from ΛCDM expansion: H(z) ∼ (1 + z)3/2 at z > 2, at the 5–10% level, testable by DESI and Euclid. Units: c = 1 unless stated otherwise.
