"key_insights": [
"TwoSidedDual wins EVERY price condition and budget level — 2.3× more clicks than DualOGD",
"Optimal epsilon for TwoSidedDual: ε=0.003 (low) — needs slow, stable pacing",
"Optimal epsilon for DualOGD: ε=0.03 (high) — needs fast adaptation since it only has cap constraint",
"k=0.95 is optimal for TwoSidedDual — near-full budget utilization matters most",
"Low-competition markets give 3-4× more clicks than high-competition (292 vs 170 for TwoSidedDual)",
"ValueShading is 42% behind TwoSidedDual — closed-form shading can't match grid-search optimization"
