Finite-Relaxation Geometry (FRG) assumes that spacetime geometry relaxes toward equilibrium over a finite timescale while retaining memory of past curvature perturbations. Although no microscopic relaxation mechanism is specified, the relaxation time cannot be arbitrary. We identify qualitative constraints imposed by causality, stability of gravitationally bound systems, galactic halo phenomenology, and cosmological observations. These constraints restrict admissible relaxation regimes and establish a hierarchical structure of geometric memory across scales. The framework reduces to general relativity in appropriate limits while remaining observationally distinguishable and falsifiable at macroscopic scales.
