Same as Figure 7, now including the disk substructure detection rate from the CAMPOS survey analysis of C.-H. Hsieh et al. (2025) (gray diamonds and shaded region; right axis). The shaded region denotes the reported 1σ uncertainty from the counting statistics of the detection fraction. The increase in substructure occurrence toward higher T_bol coincides with lower measured dust scale heights, suggesting a connection between dust settling and the emergence of observable disk substructures.
