## 1. Implementation
- [ ] 1.1 Add YAML/runtime configuration surface and strict validation diagnostics for controller auto-design/tuning assistants for common converter topologies (PI/PID current and voltage loops).
- [ ] 1.2 Implement backend runtime path for controller auto-design/tuning assistants for common converter topologies (PI/PID current and voltage loops) with deterministic behavior.
- [ ] 1.3 Expose Python API/bindings surface where applicable.
- [ ] 1.4 Add benchmark and regression coverage for nominal/failure scenarios.
- [ ] 1.5 Document user workflow and migration notes.
