Caption: Figure 4.

Per-class summary diagnostics. Top: F1 scores by class (radar plot) shown for all four regimes (different markers with distinct colors and linestyles). Bottom: per-class ROC curves and AUC values; the low-FPR region (left) is most relevant for building clean follow-up target lists. Both panels reflect the same trend seen in Figure 3: SSDA boosts the quasar subclasses while leaving GALAXY/STAR essentially saturated.
