**Completed:** January 11, 2026  
**Duration:** ~3 hours  
**Commits:** 4960f43, 9b3b299

---

## Summary

Integrated all Blockly components into the Noodl editor, creating a complete visual logic building system with runtime execution.

---

## Completed Steps

### Step 1-5: Canvas Tabs Integration ✅

- Integrated BlocklyWorkspace with CanvasTabs system
- Tab opens via `LogicBuilder.OpenTab` event
- Auto-save workspace changes to node
- Handle node deletion (closes tabs)
- Tab switching and state management

**Files:**

- `CanvasTabs.tsx` - Added Logic Builder tab support
- `CanvasTabsContext.tsx` - Tab state management

### Step 6: Property Panel Button ✅

- Created `LogicBuilderWorkspaceType` custom editor
- Styled "✨ Edit Logic Blocks" button
- Emits `LogicBuilder.OpenTab` event on click
- Registered in property editor port mapping

**Files:**

- `LogicBuilderWorkspaceType.ts` - NEW custom editor
- `Ports.ts` - Registered custom editor type
- `logic-builder.js` - Added `editorType` to workspace input

### Step 7: Code Generation & Port Detection ✅

- Created `BlocklyEditorGlobals` to expose utilities
- Runtime node accesses IODetector via `window.NoodlEditor`
- Dynamic port creation from workspace analysis
- Code generation for runtime execution

**Files:**

- `BlocklyEditorGlobals.ts` - NEW global namespace
- `logic-builder.js` - Injected IODetector integration
- `index.ts` - Import globals on initialization

## Key Features

### 1. Seamless UI Integration

- Logic Builder nodes work like any other Noodl node
- Property panel button opens editor
- Tabs provide familiar editing experience
- Changes auto-save continuously

### 2. Dynamic Port Detection

- Ports created automatically from blocks
- Supports inputs, outputs, and signals
- Type inference from block usage
- Updates on workspace changes

### 3. Code Generation

- Blocks → JavaScript conversion
- Full Noodl API access (Variables, Objects, Arrays)
- Error handling and debugging support
- Runtime execution in node context

### 4. Event-Driven Architecture

- `LogicBuilder.OpenTab` - Opens editor tab
- `LogicBuilder.WorkspaceChanged` - Updates ports
- Clean separation of concerns
- Testable components

## Testing Checklist

### Manual Testing Required

- [ ] Create Logic Builder node in node graph
- [ ] Click "Edit Logic Blocks" button
- [ ] Verify Blockly editor opens in tab
- [ ] Add "Define Input" block
- [ ] Add "Define Output" block
- [ ] Add logic blocks
- [ ] Verify ports appear on node
- [ ] Connect node to other nodes
- [ ] Trigger signal input
- [ ] Verify output values update
- [ ] Close tab, reopen - state preserved
- [ ] Delete node - tab closes

### Known Limitations

- Port updates require parameter save (not live)
- No validation of circular dependencies
- Error messages basic (needs improvement)
- Undo/redo for blocks not implemented

---

1. Manual end-to-end testing
2. Fix any discovered issues
3. Add error boundaries
4. Improve user feedback

### Phase E: Documentation (Est: 1h)

1. User guide for Logic Builder
2. Block reference documentation
3. Example projects
4. Video tutorial

### Future Enhancements (Phase F+)

1. Custom block library
2. Block search/filtering
3. Code preview panel
