Projected 1σ, 2σ, and 5σ contours for the w₀ and w_a parameters of dynamical dark energy, and an inset zoomed in around ΛCDM (w₀ = −1, w_a = 0). We combine the current data baseline (gray, DESI BAO+CMB+Union3+low-z SNe as described in Section 2) with 1 yr of DESI’s current transient program (blue), and our proposed survey with SNe actively triggering tile visits (orange). Without increasing total effective observing time, this would lead to significantly tighter constraints, excluding ΛCDM at >5σ for the current best-fit point.
