a-e, ρ as a function of n and D in all five devices acquired at B = 0 T. All are acquired at T = 2 K, except for c which is acquired at T = 20 mK. f-j, Corresponding RH for the same devices. The maps in f, h and i are antisymmetrized at B = 0.5 T, the map in g is antisymmetrized at B = 0.1 T, and the map in j is acquired at B = + 0.5 T but not antisymmetrized. k-o, Schematics of the phase diagram for each device. Blue corresponds to four-fold degeneracy, green corresponds to two-fold degeneracy, and orange indicates no remaining degeneracy. The dark gray lines denote CI states. The light gray coloring corresponds to experimentally inaccessible regions of the phase diagram.
