This paper develops the cosmological sector of Quantum Resonant Gravity (QRG), an infrared scalar–tensor resonance framework in which a dimensionless scalar field and its normalized gradient define emergent matter and optical metrics. The modified Friedmann equations reproduce the background expansion history of ΛCDM without requiring a fundamental cosmological constant. Gravitational slip alters the growth of structure, reducing the required dark‑matter fraction at galactic and cluster scales. The theory remains consistent with precision tests of general relativity while offering new observational signatures for upcoming surveys. This work extends the QRG programme by linking the theoretical foundations (QRG I–VI) to cosmological dynamics.
