Circuit List Editor Known Limitations

Existing Circuit and CircuitDeviceRow cell edits use persistent project commands and project-wide toolbar undo/redo. The editor's visible stack is still session-local, is empty after reload and still contains direct structural/destructive operations during the cutover.
Server-side project revisions and persistent undo/redo eligibility exist for the command types documented in circuit-list-editor-api.md; complete editor command coverage and history reconstruction are not complete.
Named logical project snapshots and restore are not implemented yet.
No Revit/CSV/IFCGUID import and export workflow is implemented yet.
Persistence currently targets local SQLite; PostgreSQL is an architectural option, not an implemented runtime.
The global device library supports basic CRUD and copy operations, but has no versioning, permissions or controlled synchronization model.
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 UI and server endpoints are removed; retained source rows and migration mappings remain available only for upgrade traceability.
