""" Integration Test for Task 1.2: LLMOptimizationRunner Production Wiring This test verifies the complete integration of LLM mode with the production runner. It tests the end-to-end workflow without running actual FEM simulations. Test Coverage: 1. LLM workflow analysis (mocked) 2. Model updater interface 3. Simulation runner interface 4. LLMOptimizationRunner initialization 5. Extractor generation 6. Hook generation 7.
