+## What this dataset tests
+
+Baseline coherence between:
+
+absorbed EUV power per projection mirror  
+cooling and thermal environment  
+resulting thermo-mechanical deformation modes
+
+This is the first layer needed to forecast overlay drift.
+
+## Task
+
+Given power and environment inputs, predict:
+
+coherence_score
+
+A scalar 0..1 describing how predictable deformation is from absorbed power and thermal conditions.
+
