# Circuit List Editor Known Limitations

- Undo/redo history is session-local only.
- Undo/redo history is not persisted across reloads or between users.
- No global cross-project device library workflow is implemented yet.
- Final electrical sizing logic is not implemented yet.
- No full norm-compliant voltage-drop and protection-dimensioning calculation flow yet.
- Sorting is view-only until users explicitly apply sorted order.
- Cross-section circuit drag-reorder is intentionally blocked.
- Legacy consumer and circuit-first paths coexist; migration is transitional and still requires operational discipline.
