Summary: A locality-based truncation framework for estimating time-integrated observables in lattice quantum simulations. Lieb-Robinson bounds control spatial truncation error and yield local-simulation query bounds for fermionic, bosonic, and Lindbladian systems, supported by applications and numerical experiments.
