Final planetary architectures for the three inner-edge prescriptions at ∼50 Myr (FIX, OUT[M], and IN[C]). Circles mark planets at the end of each run, where the size and color correspond to their mass: ∼0.4-1 M_⊕ in blue, 1-3 M_⊕ in pink, and 3-6 M_⊕ in brown. The dashed red line indicates the approximate 1-day period for a (0.1 M_⊙) star (USP boundary). The shaded band shows the range swept by r_in during the gas phase, with dashed gray snapshots at 1, 5, and 10 Myr (or constant) and an arrow for the direction of motion (constant in FIX, outward in OUT[M], inward in IN[C]).
