Phase 3.1 completes the ZERO-MANUAL-CODING automation pipeline by
integrating all phases into a seamless workflow from natural language
request to final objective value.
Key Features:
- ExtractorOrchestrator integrates Phase 2.7 LLM + Phase 3.0 Research Agent
- Automatic extractor generation from LLM workflow output
- Dynamic loading and execution on real OP2 files
- Smart parameter filtering per extraction pattern type
- Multi-extractor support in single workflow
- Complete end-to-end test passed on real bracket OP2
Complete Automation Pipeline:
User Natural Language Request
↓
Phase 2.7 LLM Analysis
↓
Phase 3.1 Orchestrator
↓
Phase 3.0 Research Agent (auto OP2 code gen)
↓
Generated Extractor Modules
↓
Dynamic Execution on Real OP2
↓
Phase 2.8 Inline Calculations
↓
Phase 2.9 Post-Processing Hooks
↓
Final Objective → Optuna
Test Results:
- Generated displacement extractor: PASSED
- Executed on bracket OP2: PASSED
- Extracted max_displacement: 0.361783mm at node 91
- Calculated normalized objective: 0.072357
- Multi-extractor generation: PASSED
New Files:
- optimization_engine/extractor_orchestrator.py (380+ lines)
- tests/test_phase_3_1_integration.py (200+ lines)
- docs/SESSION_SUMMARY_PHASE_3_1.md (comprehensive documentation)
- optimization_engine/result_extractors/generated/ (auto-generated extractors)
Modified Files:
- README.md - Added Phase 3.1 completion status
ZERO MANUAL CODING - Complete automation achieved!
