+═══ Cold vs Warm ═══
+  fibonacci      cold=5.0  warm=10.0  Δ=+5.0 ✓
+  factorial      cold=1.0  warm=10.0  Δ=+9.0 ✓
+
+═══ Cross-Task Transfer (['fibonacci', 'factorial'] → ['palindrome', 'fizzbuzz']) ═══
+  30 heuristics transferred
+  palindrome: ✗ Φ=10.0
+  fizzbuzz: ✗ Φ=10.0
+
+═══ Adversarial Robustness: 100% (8/8) ═══
+
+═══ VERDICT ═══
+  ✓ Self-improvement: Φ increases across runs
+  ✓ Cold/warm: memory helps (positive delta)
+  ✓ Immune system: 100% adversarial accuracy
