  "abstract": "Starting from the retarded solution of linearized General Relativity and coarse-graining over galactic scales, a minimal constitutive law emerges — one that requires no new particles, only a finite relaxation time for the weak-field geometric response.\n\nThe same framework predicts, without fitting to lensing data, an optical projection amplitude A_rel = 19/15 = 1.267, matching the KiDS/GAMA weak-lensing measurement at 0.01σ.\n\nMulti-regime tests across galactic rotation curves, halo-mass benchmarks, strong lensing, radio-relic cluster mergers, and peculiar velocity environments all support the same constitutive response.\n\nThe result is a compact, falsifiable effective theory in which dark-sector phenomenology is delayed weak-field geometry rather than unseen mass.",
