Two decades after its discovery, cosmic acceleration remains the most profound mystery in cosmology and arguably in all of physics. Either the Universe is dominated by a form of dark energy with exotic physical properties not predicted by standard model physics, or General Relativity is not an adequate description of gravity over cosmic distances. WFIRST emerged as a top priority of Astro2010 in part because of its ability to address the mystery of cosmic acceleration through both high precision measurements of the cosmic expansion history and the growth of cosmic structures with multiple and redundant probes. We illustrate in this white paper how mission design changes since Astro2010 have made WFIRST an even more powerful dark energy facility and have improved the ability of WFIRST to respond to changes in the experimental landscape. WFIRST is the space-based probe of DE the community needs in the mid-2020s.

Baryons in the Darkest Sites of the Universe
Stacking 3455 CHIME/FRB sightlines on 1288 SDSS voids shows a 3.2 sigma DM deficit toward centers, implying 60 percent baryon underdensity consistent with galaxy underdensity and hydrodynamical simulations.

Disentangling cosmic distance tensions with early and late dark energy
Early dark energy resolves CMB-BAO tension and, combined with thawing quintessence, reduces overall cosmological tensions without phantom crossing.

Cosmic Shear constraints from HSC Year 3 with clustering calibration of the tomographic redshift distributions from DESI
Reanalysis of HSC Y3 cosmic shear with DESI clustering redshift calibration yields S8 = 0.805 ± 0.018, a 1.8× error reduction and upward shift toward Planck cosmology.
