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 = D₀²/ (3c²) without fine-tuning, (iii) the Schrödinger 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 CDM expansion: H (z) (1+z) ^3/2 at z>2, at the 5–10% level, testable by DESI and Euclid.
