+Atomizer Validators
+==================
+
+Validation modules for ensuring correct configurations, model setups,
+and optimization results.
+
+Available validators:
+- config_validator: Validate optimization_config.json files
+- model_validator: Validate NX model files and simulation setup
+- results_validator: Validate optimization results in study.db
+- study_validator: Complete study health check (combines all validators)
