Zone filling** - Copper pours created but not filled automatically - Cause: SWIG API segfault when calling `ZONE_FILLER` - Workaround: Zones are filled automatically when opened in KiCAD UI - Fix: Will be resolved with IPC backend (Week 3) **3. UI manual reload** - User must manually reload to see MCP changes - Impact: Workflow friction (~2 seconds) - Workaround: File → Revert or close/reopen PCB editor - Fix: IPC backend will enable automatic refresh (Week 3) --- ## Current Progress ### Week 2 Goals (NEARLY COMPLETE) **Must Have:** 1. **Component library integration** → 153 libraries auto-discovered, search working 2. **Routing operations** → All operations tested and working with KiCAD 9.0 3. **JLCPCB integration** → Planned and designed, ready to implement **Should Have:** 4.
