This paper introduces a phenomenological two-step framework, termed REMLER (Recalibration of Measured Local Expansion Rates), designed to explore the geometric scaling of cosmic expansion parameters. By relaxing the strict spatial flatness constraint within the standard FLRW metric while adhering to a constant cosmological constant Lambda, we demonstrate a consistent geometric alignment between global cosmic microwave background (CMB) datasets (such as the Planck 2018 baseline 𝐻0=63.6−2.3+2.1 km/s/Mpc and the recent DESI 2025 re-analysis 𝐻0=63.3−2.1+2.1 km/s/Mpc) and independent local measurements.Applying the REMLER approach to a spherically closed manifold shows that local 𝐻0values in the range 70.39 to 76.5 km/s/Mpc naturally recalibrate into a narrower corridor of 65.03–61.25 km/s/Mpc.Assuming that the global evolution of the universe is governed by the Friedmann equations derived from Einstein's field equations without introducing modified physics or speculative free parameters, the REMLER solution yields the following stable physical parameters for the present-day universe: the mathematical center of the global Hubble constant reaches a value of 𝐻0=63.14−1.89+1.89 km/s/Mpc, with a cosmic age of 𝑡0=14.27−0.22+0.25 Gyr, a cosmic radius of 𝑅0=146.6−20.0+56.0 Gly, and a deceleration parameterof 𝑞0=−0.477−0.024+0.023.
