## 🔧 Technical Notes

### Backwards Compatibility
The implementation includes lazy migration for old glazing data:
- Old format: `{ glazeIds: [...], application: '...', coats: 2 }`
- New format: `{ glazeLayers: [{glazeId, application, position, coats, notes}] }`
- On read, old data is automatically converted to new format

### Database Migration
Migration v7→v8 uses `ALTER TABLE` to add columns, preserving existing data.
New tables are created from scratch.

### Type Safety
All new types are discriminated unions with type guards, maintaining the existing pattern.

   - Verify all existing data is preserved
   - Confirm new tables are created

2. **Test New Features**
   - Create a forming step with all fields
   - Create a firing step with kiln details
   - Create a glazing step with multiple layers
   - Test shopping and wish lists
   - Test weight unit toggle in Settings
   - Test data export

3. **End-to-End Testing**
   - Create a complete project with all step types
   - Verify auto-save works
   - Test backwards compatibility
   - Verify navigation flows
