+## 13. UI Styling Rules
+
+> **CRITICAL:** Before any UI/CSS work, read `dev-docs/reference/UI-STYLING-GUIDE.md`
+
+### 13.1 Never Use Hardcoded Colors
+
+```scss
+// ❌ BAD - copying legacy patterns
+.Card {
+  background-color: #27272a;
+  color: #b8b8b8;
+}
+
+// ✅ GOOD - using design tokens
+.Card {
+  background-color: var(--theme-color-bg-3);
+  color: var(--theme-color-fg-default);
+}
+```
+
+### 13.2 Quick Token Reference
+
+| Purpose           | Token                          |
+| ----------------- | ------------------------------ |
+| Panel backgrounds | `--theme-color-bg-2`           |
+| Card backgrounds  | `--theme-color-bg-3`           |
+| Normal text       | `--theme-color-fg-default`     |
+| Secondary text    | `--theme-color-fg-default-shy` |
+| Emphasized text   | `--theme-color-fg-highlight`   |
+| Primary buttons   | `--theme-color-primary`        |
+| Borders           | `--theme-color-border-default` |
+
+### 13.3 Legacy Files Warning
+
+DO NOT copy patterns from these files (they have hardcoded colors):
+
+- `packages/noodl-editor/src/editor/src/styles/popuplayer.css`
+- `packages/noodl-editor/src/editor/src/styles/propertyeditor.css`
+
+DO reference these files (they use proper patterns):
+
+- `packages/noodl-core-ui/src/components/layout/BaseDialog/`
+- `packages/noodl-core-ui/src/components/inputs/PrimaryButton/`
+
+### 13.4 Before Completing UI Tasks
+
+Verify:
+
+- [ ] No hardcoded hex colors (`grep -E '#[0-9a-fA-F]{3,6}' your-file.scss`)
+- [ ] All colors use `var(--theme-color-*)` tokens
+- [ ] Hover/focus/disabled states defined
+

+
+## Section: React + EventDispatcher Integration
+
+````markdown
+## React + EventDispatcher Integration
+
+### CRITICAL: Always use useEventListener hook
+
+When subscribing to EventDispatcher events from React components, ALWAYS use the `useEventListener` hook. Direct subscriptions silently fail.
+
+**Hook location:** `@noodl-hooks/useEventListener`
+
+**✅ CORRECT - Always do this:**
+
+```typescript
+import { useEventListener } from '@noodl-hooks/useEventListener';
+
+import { ProjectModel } from '@noodl-models/projectmodel';
+
+function MyComponent() {
+  useEventListener(ProjectModel.instance, 'componentRenamed', (data) => {
+    // This works!
+  });
+}
+```
+````
+
+**❌ BROKEN - Never do this:**
+
+```typescript
+// This compiles and runs without errors, but events are NEVER received
+useEffect(() => {
+  const context = {};
+  ProjectModel.instance.on('event', handler, context);
+  return () => ProjectModel.instance.off(context);
+}, []);
+```
+
+### Why this matters
+
+EventDispatcher uses a context-object cleanup pattern incompatible with React closures. Direct subscriptions fail silently - no errors, no events, just confusion.
+
+This pattern was established in Phase 0 after discovering the issue in TASK-004B.
+
+### Available dispatchers
+
+- `ProjectModel.instance` - component changes, settings
+- `NodeLibrary.instance` - library/module changes
+- `WarningsModel.instance` - validation warnings
+- `EventDispatcher.instance` - global events
+- `UndoQueue.instance` - undo/redo state
+
+### Full documentation
+
+See: `dev-docs/patterns/REACT-EVENTDISPATCHER.md`

+## Section: Webpack Cache Issues
+
+```markdown
+## Webpack Cache Issues
+
+### If code changes don't appear
+
+When editing code and changes don't load in the running app:
+
+1. **First, run `npm run clean:all`** - This nukes all caches
+2. **Restart the dev server** - Don't just refresh
+3. **Check for the build canary** - Console should show `🔥 BUILD TIMESTAMP: [recent time]`
+
+If the canary shows an old timestamp, caching is still an issue. Check:
+- Electron app cache (platform-specific location)
+- Any lingering node/Electron processes (`pkill -f node; pkill -f Electron`)
+- Browser cache (hard refresh with Cmd+Shift+R)
+
+### Never debug without verifying fresh code
+
+Before spending time debugging, ALWAYS verify your code changes are actually running:
+
+1. Add a distinctive console.log: `console.log('🔥 MY CHANGE LOADED:', Date.now())`
+2. Save the file
+3. Check if the log appears
+4. If not, clear caches and restart
+
+This avoids wasting hours debugging stale code.
+
+### Webpack config notes
+
+- Dev mode should NOT use `cache: { type: 'filesystem' }`
+- Memory cache or no cache is preferred for development
+- Production can use filesystem cache for CI speed
+````
+
+---
+
+## Section: Foundation Health
+
+```markdown
+## Foundation Health Check
+
+### When to run
+
+Run `npm run health:check` when:
+
+- Starting work after a break
+- After updating dependencies
+- When things "feel broken"
+- Before investigating mysterious bugs
+
+### What it checks
+
+1. Cache state (not stale/oversized)
+2. Webpack config (correct cache settings)
+3. useEventListener hook (present and exported)
+4. Direct EventDispatcher subscriptions (anti-pattern detection)
+5. Build canary (present in entry)
+6. Package versions (no known problematic versions)
+
+### Interpreting results
+
+- ✅ Pass: All good
+- ⚠️ Warning: Works but could be improved
+- ❌ Fail: Must fix before proceeding
+```
+
+---
+
+## Section: Debugging React Migrations
+
+````markdown
+## Debugging Legacy → React Migrations
+
+### Common issue: UI doesn't update after action
+
+If you perform an action (rename, add, delete) and the UI doesn't update:
+
+1. **Check if the action succeeded** - Look in console for success logs
+2. **Check if event was emitted** - Add logging to the model method
+3. **Check if event was received** - Add logging in useEventListener callback
+4. **Check if component re-rendered** - Add console.log in component body
+
+Usually the problem is:
+
+- ❌ Using direct `.on()` instead of `useEventListener`
+- ❌ Cached old code running (run `npm run clean:all`)
+- ❌ Event name mismatch (check exact spelling)
+
+### Pattern for debugging event subscriptions
+
+```typescript
+useEventListener(ProjectModel.instance, 'componentRenamed', (data) => {
+  console.log('🔔 Event received:', data); // Add this temporarily
+  // Your actual handler
+});
+```
+````
+
+If you don't see the log, the subscription isn't working.

+## 14. Node Creation Checklist
+
+> **🚨 CRITICAL:** Before creating or modifying runtime nodes, read `dev-docs/reference/LEARNINGS-NODE-CREATION.md`
+
+Creating nodes in OpenNoodl is deceptively tricky. This checklist prevents the most common (and hardest to debug) issues.
+
+### 14.1 Pre-Flight Checklist
+
+Before writing any node code:
+
+- [ ] Read `dev-docs/reference/LEARNINGS-NODE-CREATION.md` (especially the CRITICAL GOTCHAS section)
+- [ ] Check `dev-docs/reference/LEARNINGS.md` for recent node-related discoveries (search for "node", "runtime", "coreNodes")
+- [ ] Study an existing working node of similar complexity (e.g., `restnode.js` for data nodes)
+- [ ] Understand the difference between `inputs` (static) vs `prototypeExtensions` (instance methods)
+- [ ] Know where your node should be registered (noodl-runtime vs noodl-viewer-react)
+
+### 14.2 Input Handler Rules
+
+```javascript
+// ✅ CORRECT: Signal inputs use valueChangedToTrue
+inputs: {
+  fetch: {
+    type: 'signal',
+    valueChangedToTrue: function() {
+      this.scheduleFetch();
+    }
+  }
+}
+
+// ❌ WRONG: Signal inputs with set() - NEVER TRIGGERS
+inputs: {
+  fetch: {
+    type: 'signal',
+    set: function(value) { // ☠️ Never called for signals
+      this.scheduleFetch();
+    }
+  }
+}
+```
+
+### 14.3 Never Override setInputValue
+
+```javascript
+// ❌ BREAKS EVERYTHING - Never define setInputValue in prototypeExtensions
+prototypeExtensions: {
+  setInputValue: function(name, value) { // ☠️ Overrides base - signals stop working
+    // ...
+  }
+}
+
+// ✅ Use a different name for custom storage
+prototypeExtensions: {
+  _storeInputValue: function(name, value) { // ✅ Doesn't override anything
+    this._internal.inputValues[name] = value;
+  }
+}
+```
+
+### 14.4 Dynamic Ports Must Include Static Ports
+
+```javascript
+// ❌ WRONG - Static ports disappear
+function updatePorts(nodeId, parameters, editorConnection) {
+  const ports = [];
+  // Only adds dynamic ports...
+  editorConnection.sendDynamicPorts(nodeId, ports); // Static inputs gone!
+}
+
+// ✅ CORRECT - Include all ports
+function updatePorts(nodeId, parameters, editorConnection) {
+  const ports = [
+    // Re-add static inputs
+    { name: 'url', displayName: 'URL', type: 'string', plug: 'input', group: 'Request' },
+    { name: 'fetch', displayName: 'Fetch', type: 'signal', plug: 'input', group: 'Actions' },
+    // Then add dynamic ports...
+  ];
+  editorConnection.sendDynamicPorts(nodeId, ports);
+}
+```
+
+### 14.5 Register Config Inputs Explicitly
+
+```javascript
+// Config inputs (from stringlist editors) need explicit registration
+registerInputIfNeeded: function(name) {
+  if (this.hasInput(name)) return;
+
+  // Map config names to their setters
+  const configSetters = {
+    'method': this.setMethod.bind(this),
+    'headers': this.setHeaders.bind(this),
+    'queryParams': this.setQueryParams.bind(this)
+  };
+
+  if (configSetters[name]) {
+    return this.registerInput(name, { set: configSetters[name] });
+  }
+
+  // Handle prefixed dynamic inputs
+  if (name.startsWith('header-')) {
+    return this.registerInput(name, {
+      set: this._storeInputValue.bind(this, name)
+    });
+  }
+}
+```
+
+### 14.6 Export Format Matters
+
+```javascript
+// ✅ CORRECT: Export with setup function
+module.exports = {
+  node: MyNode,
+  setup: function (context, graphModel) {
+    // Port management goes here
+  }
+};
+
+// ❌ WRONG: Direct export (setup never runs)
+module.exports = MyNode;
+```
+
+### 14.7 Post-Creation Verification
+
+After creating a node:
+
+1. **Check ports appear**: All static AND dynamic inputs/outputs visible in editor?
+2. **Check signals work**: Add console.log in `valueChangedToTrue` - does it print?
+3. **Check config inputs work**: Change dropdown/stringlist values - does setter get called?
+4. **Clear caches if needed**: `npm run clean:all` and restart
+
+### 14.8 Quick Reference
+
+| Input Type                   | Handler                     | Callback Format             |
+| ---------------------------- | --------------------------- | --------------------------- |
+| Signal                       | `valueChangedToTrue`        | `function() { ... }`        |
+| Value (string, number, etc.) | `set`                       | `function(value) { ... }`   |
+| Enum (dropdown)              | `set`                       | `function(value) { ... }`   |
+| StringList (config)          | Needs explicit registration | Via `registerInputIfNeeded` |
+
+### 14.9 Where to Find Examples
+
+| Pattern                              | Example File                                                     |
+| ------------------------------------ | ---------------------------------------------------------------- |
+| Complex data node with dynamic ports | `noodl-runtime/src/nodes/std-library/data/restnode.js`           |

+## 🚨 CRITICAL: OpenNoodl is an Electron Desktop Application
+
+**OpenNoodl Editor is NOT a web application.** It is exclusively an Electron desktop app.
+
+### What This Means for Development:
+
+- ❌ **NEVER** try to open it in a browser at `http://localhost:8080`
+- ❌ **NEVER** use `browser_action` tool to test the editor
+- ✅ **ALWAYS** `npm run dev` automatically launches the Electron app window
+- ✅ **ALWAYS** use Electron DevTools for debugging (View → Toggle Developer Tools in the Electron window)
+- ✅ **ALWAYS** test in the actual Electron window that opens
+
+### Testing Workflow:
+
+```bash
+# 1. Start development
+npm run dev
+
+# 2. Electron window launches automatically
+# 3. Open Electron DevTools: View → Toggle Developer Tools
+# 4. Console logs appear in Electron DevTools, NOT in terminal
+```
+
+**Architecture Overview:**
+
+- **Editor** (this codebase) = Electron desktop app where developers build
+- **Viewer/Runtime** = Web apps that run in browsers (what users see)
+- **Storybook** = Web-based component library (separate from main editor)
+
+The `localhost:8080` webpack dev server is internal to Electron - it's not meant to be accessed directly via browser.

+## 🖥️ Architecture: Desktop vs Web
+
+**Critical Distinction for Development:**
+
+| Component        | Runtime          | Access Method                         | Purpose                       |
+| ---------------- | ---------------- | ------------------------------------- | ----------------------------- |
+| **Editor** ⚡    | Electron Desktop | `npm run dev` → auto-launches window  | Development environment       |
+| **Viewer** 🌐    | Web Browser      | Deployed URL or preview inside editor | User-facing applications      |
+| **Runtime**      | Node.js/Browser  | Embedded in viewer                    | Application logic engine      |
+| **Storybook** 🌐 | Web Browser      | `npm run start:storybook` → browser   | Component library development |
+
+**Important for Testing:**
+
+- When working on the **editor**, you're always in Electron
+- Never try to open `http://localhost:8080` in a browser - that's the webpack dev server internal to Electron
+- The editor automatically launches as an Electron window when you run `npm run dev`
+- Use Electron DevTools (View → Toggle Developer Tools) for debugging the editor
+- Console logs from the editor appear in Electron DevTools, NOT in the terminal

+### React Component Not Receiving Events
+
+**Symptom**: ProjectModel/NodeLibrary events fire but React components don't update
+
+**Solutions**:
+
+1. **Check if using `useEventListener` hook** (most common issue):
+
+   ```typescript
+   // ✅ RIGHT - Always use useEventListener
+   import { useEventListener } from '@noodl-hooks/useEventListener';
+
+   // ❌ WRONG - Direct .on() silently fails in React
+   useEffect(() => {
+     ProjectModel.instance.on('event', handler, {});
+   }, []);
+
+   useEventListener(ProjectModel.instance, 'event', handler);
+   ```
+
+2. **Check singleton dependency in useEffect**:
+
+   ```typescript
+   // ❌ WRONG - Runs once before instance exists
+   useEffect(() => {
+     if (!ProjectModel.instance) return;
+     ProjectModel.instance.on('event', handler, group);
+   }, []); // Empty deps!
+
+   // ✅ RIGHT - Re-runs when instance loads
+   useEffect(() => {
+     if (!ProjectModel.instance) return;
+     ProjectModel.instance.on('event', handler, group);
+   }, [ProjectModel.instance]); // Include singleton!
+   ```
+
+3. **Verify code is loading**:
+
+   - Add `console.log('🔥 Module loaded')` at top of file
+   - If log doesn't appear, clear caches (see Webpack issues below)
+
+4. **Check event name matches exactly**:
+   - ProjectModel events: `componentRenamed`, `componentAdded`, `componentRemoved`
+   - Case-sensitive, no typos
+
+**See also**:

+
+### Undo Action Doesn't Execute
+
+**Symptom**: Action returns success and appears in undo history, but nothing happens
+
+**Solutions**:
+
+1. **Check if using broken pattern**:
+
+   ```typescript
+   // ❌ WRONG - Silent failure due to ptr bug
+   const undoGroup = new UndoActionGroup({ label: 'Action' });
+   UndoQueue.instance.push(undoGroup);
+   undoGroup.push({ do: () => {...}, undo: () => {...} });
+   undoGroup.do(); // NEVER EXECUTES
+
+   // ✅ RIGHT - Use pushAndDo
+   UndoQueue.instance.pushAndDo(
+     new UndoActionGroup({
+       label: 'Action',
+       do: () => {...},
+       undo: () => {...}
+     })
+   );
+   ```
+
+2. **Add debug logging**:
+
+   ```typescript
+   do: () => {
+     console.log('🔥 ACTION EXECUTING'); // Should print immediately
+     // Your action here
+   }
+   ```
+
+   If log doesn't print, you have the ptr bug.
+
+3. **Search codebase for broken pattern**:
+   ```bash
+   grep -r "undoGroup.push" packages/
+   grep -r "undoGroup.do()" packages/
+   ```
+   If these appear together, fix them.

+- [LEARNINGS.md - UndoActionGroup](./LEARNINGS.md#-critical-undoactiongroupdo-silent-failure-dec-2025)
+
+### Webpack Cache Preventing Code Changes
+
+**Symptom**: Code changes not appearing despite save/restart
+
+**Solutions**:
+
+1. **Verify code is loading** (add module marker):
+
+   ```typescript
+   // At top of file
+   console.log('🔥 MyFile.ts LOADED - Version 2.0');
+   ```
+
+   If this doesn't appear in console, it's a cache issue.
+
+2. **Nuclear cache clear** (when standard restart fails):
+
+   ```bash
+   # Kill processes
+   killall node
+   killall Electron
+
+   # Clear ALL caches
+   rm -rf packages/noodl-editor/node_modules/.cache
+   rm -rf ~/Library/Application\ Support/Electron
+   rm -rf ~/Library/Application\ Support/OpenNoodl  # macOS
+
+   # Restart
+   npm run dev
+   ```
+
+3. **Check build timestamp**:
+
+   - Look for `🔥 BUILD TIMESTAMP:` in console
+   - If timestamp is old, caching is active
+
+4. **Verify in Sources tab**:
+   - Open Chrome DevTools
+   - Go to Sources tab
+   - Find your file
+   - Check if changes are there
+

+## ⚠️ CRITICAL GOTCHAS - READ BEFORE CREATING NODES
+
+These issues will cause silent failures with NO error messages. They were discovered during the HTTP node debugging session (December 2024) and cost hours of debugging time.
+
+---
+
+### 🔴 GOTCHA #1: Never Override `setInputValue` in prototypeExtensions
+
+**THE BUG:**
+
+```javascript
+// ❌ DEADLY - This silently breaks ALL signal inputs
+prototypeExtensions: {
+  setInputValue: function (name, value) {
+    this._internal.inputValues[name] = value;  // Signal setters NEVER called!
+  }
+}
+```
+
+**WHY IT BREAKS:**
+
+- `prototypeExtensions.setInputValue` **completely overrides** `Node.prototype.setInputValue`
+- The base method contains `input.set.call(this, value)` which triggers signal callbacks
+- Without it, signals never fire - NO errors, just silent failure
+
+**THE FIX:**
+
+```javascript
+// ✅ SAFE - Use a different method name for storing dynamic values
+prototypeExtensions: {
+  _storeInputValue: function (name, value) {
+    this._internal.inputValues[name] = value;
+  },
+
+  registerInputIfNeeded: function (name) {
+    // Register dynamic inputs with _storeInputValue, not setInputValue
+    if (name.startsWith('body-')) {
+      return this.registerInput(name, {
+        set: this._storeInputValue.bind(this, name)
+      });
+    }
+  }
+}
+```
+
+---
+
+### 🔴 GOTCHA #2: Dynamic Ports REPLACE Static Ports
+
+**THE BUG:**
+
+```javascript
+// Node has static inputs defined in inputs: {}
+inputs: {
+  url: { type: 'string', set: function(v) {...} },
+  fetch: { type: 'signal', valueChangedToTrue: function() {...} }
+},
+
+// But setup function only sends dynamic ports
+function updatePorts(nodeId, parameters, editorConnection) {
+  const ports = [
+    { name: 'headers', ... },
+    { name: 'queryParams', ... }
+  ];
+  // ❌ MISSING url, fetch - they won't appear in editor!
+  editorConnection.sendDynamicPorts(nodeId, ports);
+}
+```
+
+**WHY IT BREAKS:**
+
+- `sendDynamicPorts()` tells the editor "these are ALL the ports for this node"
+- Static `inputs` are NOT automatically merged
+- The editor only shows dynamic ports, connections to static ports fail
+
+**THE FIX:**
+
+```javascript
+// ✅ SAFE - Include ALL ports in dynamic ports array
+function updatePorts(nodeId, parameters, editorConnection) {
+  const ports = [];
+
+  // Dynamic configuration ports
+  ports.push({ name: 'headers', type: {...}, plug: 'input' });
+  ports.push({ name: 'queryParams', type: {...}, plug: 'input' });
+
+  // MUST include static ports too!
+  ports.push({ name: 'url', type: 'string', plug: 'input', group: 'Request' });
+  ports.push({ name: 'fetch', type: 'signal', plug: 'input', group: 'Actions' });
+  ports.push({ name: 'cancel', type: 'signal', plug: 'input', group: 'Actions' });
+
+  // Include outputs too
+  ports.push({ name: 'success', type: 'signal', plug: 'output', group: 'Events' });
+
+  editorConnection.sendDynamicPorts(nodeId, ports);
+}
+```
+
+---
+
+### 🔴 GOTCHA #3: Configuration Inputs Need Explicit Registration
+
+**THE BUG:**
+
+```javascript
+// Dynamic ports send method, bodyType, etc. to editor
+ports.push({ name: 'method', type: { name: 'enum', ... } });
+ports.push({ name: 'bodyType', type: { name: 'enum', ... } });
+
+// ❌ Values never reach runtime - no setter registered!
+// User selects POST in editor, but doFetch() always uses GET
+doFetch: function() {
+  const method = this._internal.method || 'GET';  // Always undefined!
+}
+```
+
+**WHY IT BREAKS:**
+
+- Dynamic port values are sent to runtime as input values via `setInputValue`
+- But `registerInputIfNeeded` is only called for ports not in static `inputs`
+- If there's no setter, the value is lost
+
+**THE FIX:**
+
+```javascript
+// ✅ SAFE - Register setters for all config inputs
+prototypeExtensions: {
+  // Setter methods
+  setMethod: function (value) { this._internal.method = value || 'GET'; },
+  setBodyType: function (value) { this._internal.bodyType = value; },
+  setHeaders: function (value) { this._internal.headers = value || ''; },
+
+  registerInputIfNeeded: function (name) {
+    if (this.hasInput(name)) return;
+
+    // Configuration inputs - bind to their setters
+    const configSetters = {
+      method: this.setMethod.bind(this),
+      bodyType: this.setBodyType.bind(this),
+      headers: this.setHeaders.bind(this),
+      timeout: this.setTimeout.bind(this)
+    };
+
+    if (configSetters[name]) {
+      return this.registerInput(name, { set: configSetters[name] });
+    }
+
+    // Dynamic inputs for prefixed ports
+    if (name.startsWith('body-') || name.startsWith('header-')) {
+      return this.registerInput(name, {
+        set: this._storeInputValue.bind(this, name)
+      });
+    }
+  }
+}
+```
+
+---
+
+### 🔴 GOTCHA #4: Signal Inputs Use `valueChangedToTrue`, Not `set`
+
+**THE BUG:**
+
+```javascript
+// ❌ WRONG - This won't trigger on signal
+inputs: {
+  fetch: {
+    type: 'signal',
+    set: function() {
+      this.doFetch();  // Never called!
+    }
+  }
+}
+```
+
+**WHY IT BREAKS:**
+
+- Signal inputs don't use `set` - they use `valueChangedToTrue`
+- The runtime wraps signals with `EdgeTriggeredInput.createSetter()` which tracks state transitions
+- Signals only fire on FALSE → TRUE transition
+
+**THE FIX:**
+
+```javascript
+// ✅ CORRECT - Use valueChangedToTrue for signals
+inputs: {
+  fetch: {
+    type: 'signal',
+    displayName: 'Fetch',
+    group: 'Actions',
+    valueChangedToTrue: function () {
+      this.scheduleFetch();
+    }
+  },
+  cancel: {
+    type: 'signal',
+    displayName: 'Cancel',
+    group: 'Actions',
+    valueChangedToTrue: function () {
+      this.cancelFetch();
+    }
+  }
+}
+```
+
+---
+
+### 🔴 GOTCHA #5: Node Registration Path Matters (Signals Not Wrapping)
+
+**THE BUG:**
+
+- Nodes in `noodl-runtime/noodl-runtime.js` → Go through `defineNode()`
+- Nodes in `noodl-viewer-react/register-nodes.js` → Go through `defineNode()`
+- Raw node object passed directly → Does NOT go through `defineNode()`
+
+**WHY IT MATTERS:**
+
+- `defineNode()` in `nodedefinition.js` wraps signal inputs with `EdgeTriggeredInput.createSetter()`
+- Without `defineNode()`, signals are registered but never fire
+- The `{node, setup}` export format automatically calls `defineNode()`
+
+**THE FIX:**
+
+```javascript
+// ✅ CORRECT - Always export with {node, setup} format
+module.exports = {
+  node: MyNode, // Goes through defineNode()
+  setup: function (context, graphModel) {
+    // Dynamic port setup
+  }
+};
+
+// ✅ ALSO CORRECT - Call defineNode explicitly
+const NodeDefinition = require('./nodedefinition');
+module.exports = NodeDefinition.defineNode(MyNode);
+```
+
+---
+
+### 🔴 GOTCHA #6: Signal in Static `inputs` + Dynamic Ports = Duplicate Ports (Dec 2025)
+
+**THE BUG:**
+
+```javascript
+// Signal defined in static inputs with handler
+inputs: {
+  fetch: {
+    type: 'signal',
+    valueChangedToTrue: function() { this.scheduleFetch(); }
+  }
+}
+
+// updatePorts() ALSO adds fetch - CAUSES DUPLICATE!
+function updatePorts(nodeId, parameters, editorConnection) {
+  const ports = [];
+  // ... other ports ...
+  ports.push({ name: 'fetch', type: 'signal', plug: 'input' }); // ❌ Duplicate!
+  editorConnection.sendDynamicPorts(nodeId, ports);
+}
+```
+
+**SYMPTOM:** When trying to connect to the node, TWO "Fetch" signals appear in the connection popup.
+
+**WHY IT BREAKS:**
+
+- GOTCHA #2 says "include static ports in dynamic ports" which is true for MOST ports
+- But signals with `valueChangedToTrue` handlers ALREADY have a runtime registration
+- Adding them again in `updatePorts()` creates a duplicate visual port
+- The handler still works, but UX is confusing
+
+**THE FIX:**
+
+```javascript
+// ✅ CORRECT - Only define signal in static inputs, NOT in updatePorts()
+inputs: {
+  fetch: {
+    type: 'signal',
+    valueChangedToTrue: function() { this.scheduleFetch(); }
+  }
+}
+
+function updatePorts(nodeId, parameters, editorConnection) {
+  const ports = [];
+  // ... dynamic ports ...
+
+  // NOTE: 'fetch' signal is defined in static inputs (with valueChangedToTrue handler)
+  // DO NOT add it here again or it will appear twice in the connection popup
+
+  // ... other ports ...
+  editorConnection.sendDynamicPorts(nodeId, ports);
+}
+```
+
+**RULE:** Signals with `valueChangedToTrue` handlers → ONLY in static `inputs`. All other ports (value inputs, outputs) → in `updatePorts()` dynamic ports.
+
+---
+
+### 🔴 GOTCHA #7: Require Path Depth for noodl-runtime (Dec 2025)
+
+**THE BUG:**
+
+```javascript
+// File: src/nodes/std-library/data/mynode.js
+// Trying to require noodl-runtime.js at package root
+
+const NoodlRuntime = require('../../../noodl-runtime'); // ❌ WRONG - only 3 levels
+// This breaks the entire runtime with "Cannot find module" error
+```
+
+**WHY IT MATTERS:**
+
+- From `src/nodes/std-library/data/` you need to go UP 4 levels to reach the package root
+- Path: data → std-library → nodes → src → (package root)
+- One wrong `../` and the entire app fails to load
+
+**THE FIX:**
+
+```javascript
+// ✅ CORRECT - Count the directories carefully
+// From src/nodes/std-library/data/mynode.js:
+const NoodlRuntime = require('../../../../noodl-runtime'); // 4 levels
+
+// Reference: cloudstore.js at src/api/ uses 2 levels:
+const NoodlRuntime = require('../../noodl-runtime'); // 2 levels from src/api/
+```
+
+**Quick Reference:**
+
+| File Location                 | Levels to Package Root | Require Path                |
+| ----------------------------- | ---------------------- | --------------------------- |
+| `src/api/`                    | 2                      | `../../noodl-runtime`       |
+| `src/nodes/`                  | 2                      | `../../noodl-runtime`       |
+| `src/nodes/std-library/`      | 3                      | `../../../noodl-runtime`    |
+| `src/nodes/std-library/data/` | 4                      | `../../../../noodl-runtime` |

+## Complete Working Pattern (HTTP Node Reference)

+# UI Styling Guide for Noodl Editor
+
+> **For Cline:** Read this document before doing ANY UI/styling work in the editor.
+
+## Why This Document Exists
+
+The Noodl editor has accumulated styling debt from 2015-era development. Many components use hardcoded hex colors instead of the design token system. This guide ensures consistent, modern styling.
+
+**Key Rule:** NEVER copy patterns from legacy CSS files. They're full of hardcoded colors.
+
+---
+
+## Part 1: Token System Architecture
+
+### Token Files Location
+
+```
+packages/noodl-editor/src/editor/src/styles/custom-properties/
+├── colors.css      ← COLOR TOKENS (this is what's imported)
+├── fonts.css       ← Typography tokens
+├── animations.css  ← Motion tokens
+├── spacing.css     ← Spacing tokens (add if missing)
+```
+
+### Import Chain
+
+The editor entry point (`packages/noodl-editor/src/editor/index.ts`) imports tokens from the editor's own copies, NOT from noodl-core-ui:
+
+```typescript
+// What's actually used:
+import '../editor/src/styles/custom-properties/colors.css';
+```
+
+---
+
+## Part 2: Design Token Reference
+
+### Background Colors (Dark to Light)
+
+| Token                | Use For             | Approximate Value |
+| -------------------- | ------------------- | ----------------- |
+| `--theme-color-bg-0` | Deepest black       | `#000000`         |
+| `--theme-color-bg-1` | App/modal backdrops | `#09090b`         |
+| `--theme-color-bg-2` | Panel backgrounds   | `#18181b`         |
+| `--theme-color-bg-3` | Cards, inputs       | `#27272a`         |
+| `--theme-color-bg-4` | Elevated surfaces   | `#3f3f46`         |
+| `--theme-color-bg-5` | Highest elevation   | `#52525b`         |
+
+### Foreground Colors (Muted to Bright)
+
+| Token                               | Use For                     |
+| ----------------------------------- | --------------------------- |
+| `--theme-color-fg-muted`            | Disabled text, placeholders |
+| `--theme-color-fg-default-shy`      | Secondary/helper text       |
+| `--theme-color-fg-default`          | Normal body text            |
+| `--theme-color-fg-default-contrast` | Emphasized text             |
+| `--theme-color-fg-highlight`        | Maximum emphasis (white)    |
+
+### Brand Colors
+
+| Token                               | Use For                    | Color            |
+| ----------------------------------- | -------------------------- | ---------------- |
+| `--theme-color-primary`             | CTA buttons, active states | Rose             |
+| `--theme-color-primary-highlight`   | Primary hover states       | Rose (lighter)   |
+| `--theme-color-secondary`           | Secondary elements         | Violet           |
+| `--theme-color-secondary-highlight` | Secondary hover            | Violet (lighter) |
+
+### Status Colors
+
+| Token                   | Use For                     |
+| ----------------------- | --------------------------- |
+| `--theme-color-success` | Success states              |
+| `--theme-color-notice`  | Warnings                    |
+| `--theme-color-danger`  | Errors, destructive actions |
+
+### Border Colors
+
+| Token                          | Use For            |
+| ------------------------------ | ------------------ |
+| `--theme-color-border-subtle`  | Light dividers     |
+| `--theme-color-border-default` | Standard borders   |
+| `--theme-color-border-strong`  | Emphasized borders |

+
+---
+
+## Part 4: Spacing System
+
+Use consistent spacing based on 4px/8px grid:
+
+```scss
+4px   // --spacing-1  (tight)
+8px   // --spacing-2  (small)
+12px  // --spacing-3  (medium-small)
+16px  // --spacing-4  (default)
+20px  // --spacing-5  (medium)
+24px  // --spacing-6  (large)
+32px  // --spacing-8  (extra-large)
+40px  // --spacing-10
+48px  // --spacing-12
+```
+
+---
+
+## Part 5: Typography Scale
+
+```scss
+/* Titles */
+24px, weight 600, --theme-color-fg-highlight     // Dialog titles
+18px, weight 600, --theme-color-fg-highlight     // Section titles
+16px, weight 600, --theme-color-fg-default-contrast // Subsection headers
+
+/* Body */
+14px, weight 400, --theme-color-fg-default       // Normal text
+14px, weight 400, --theme-color-fg-default-shy   // Secondary text
+
+/* Small */
+12px, weight 400, --theme-color-fg-muted         // Captions, hints
+```
+
+---
+
+## Part 6: Component Patterns
+
+### Use CSS Modules
+
+```
+ComponentName.tsx
+ComponentName.module.scss  ← Use this pattern
+```
+
+### Standard Component Structure
+
+```scss
+// ComponentName.module.scss
+
+.Root {
+  display: flex;
+  flex-direction: column;
+  background-color: var(--theme-color-bg-2);
+  border: 1px solid var(--theme-color-border-subtle);
+  border-radius: 8px;
+  overflow: hidden;
+}
+
+.Header {
+  display: flex;
+  align-items: center;
+  justify-content: space-between;
+  padding: 16px 20px;
+  border-bottom: 1px solid var(--theme-color-border-subtle);
+}
+
+.Title {
+  font-size: 18px;
+  font-weight: 600;
+  color: var(--theme-color-fg-highlight);
+  margin: 0;
+}
+
+.Content {
+  flex: 1;
+  min-height: 0;
+  overflow-y: auto;
+  padding: 20px;
+}
+
+.Footer {
+  display: flex;
+  align-items: center;
+  justify-content: flex-end;
+  gap: 12px;
+  padding: 16px 20px;
+  border-top: 1px solid var(--theme-color-border-subtle);
+}
+```
+
+### Button Patterns
+
+```scss
+// Primary Button
+.PrimaryButton {
+  background-color: var(--theme-color-primary);
+  color: white;
+  border: none;
+  border-radius: 6px;
+  padding: 10px 20px;
+  font-weight: 600;
+  cursor: pointer;
+
+  &:hover {
+    background-color: var(--theme-color-primary-highlight);
+  }
+
+  &:disabled {
+    opacity: 0.5;
+    cursor: not-allowed;
+  }
+}
+
+// Secondary Button
+.SecondaryButton {
+  background-color: var(--theme-color-bg-3);
+  color: var(--theme-color-fg-default);
+  border: 1px solid var(--theme-color-border-default);
+  border-radius: 6px;
+  padding: 10px 20px;
+
+  &:hover {
+    background-color: var(--theme-color-bg-4);
+    color: var(--theme-color-fg-highlight);
+  }
+}

+
+Before completing any UI task, verify:
+
+- [ ] No hardcoded hex colors (search for `#` followed by hex)
+- [ ] All colors use `var(--theme-color-*)` tokens
+- [ ] Spacing uses consistent values (multiples of 4px)
+- [ ] Hover states defined for interactive elements
+- [ ] Focus states visible for accessibility
+- [ ] Disabled states handled
+- [ ] Border radius consistent (6px buttons, 8px cards)
+- [ ] No new global CSS selectors that could conflict
+
+---
+
+## Quick Grep Commands
+
+```bash
+# Find hardcoded colors in a file
+grep -E '#[0-9a-fA-F]{3,6}' path/to/file.css
+
+# Find all hardcoded colors in editor styles
+grep -rE '#[0-9a-fA-F]{3,6}' packages/noodl-editor/src/editor/src/styles/
+
+# Find usage of a specific token

+# UndoQueue Usage Patterns
+
+This guide documents the correct patterns for using OpenNoodl's undo system.
+
+---
+
+## Overview
+
+The OpenNoodl undo system consists of two main classes:
+
+- **`UndoQueue`**: Manages the global undo/redo stack
+- **`UndoActionGroup`**: Represents a single undoable action (or group of actions)
+
+### Critical Bug Warning
+
+There's a subtle but dangerous bug in `UndoActionGroup` that causes silent failures. This guide will show you the **correct patterns** that avoid this bug.
+
+---
+
+## The Golden Rule
+
+**✅ ALWAYS USE: `UndoQueue.instance.pushAndDo(new UndoActionGroup({...}))`**
+
+**❌ NEVER USE: `undoGroup.push({...}); undoGroup.do();`**
+
+Why? The second pattern fails silently due to an internal pointer bug. See [LEARNINGS.md](./LEARNINGS.md#-critical-undoactiongroupdo-silent-failure-dec-2025) for full technical details.
+
+---
+
+## Pattern 1: Simple Single Action (Recommended)
+
+This is the most common pattern and should be used for 95% of cases.
+
+```typescript
+import { ProjectModel } from '@noodl-models/projectmodel';
+import { UndoQueue, UndoActionGroup } from '@noodl-models/undo-queue-model';
+
+function renameComponent(component: ComponentModel, newName: string) {
+  const oldName = component.name;
+
+  // ✅ CORRECT - Action executes immediately and is added to undo stack
+  UndoQueue.instance.pushAndDo(
+    new UndoActionGroup({
+      label: `Rename ${component.localName} to ${newName}`,
+      do: () => {
+        ProjectModel.instance.renameComponent(component, newName);
+      },
+      undo: () => {
+        ProjectModel.instance.renameComponent(component, oldName);
+      }
+    })
+  );
+}
+```
+
+**What happens:**
+
+1. `UndoActionGroup` is created with action in constructor (ptr = 0)
+2. `pushAndDo()` adds it to the queue
+3. `pushAndDo()` calls `action.do()` which executes immediately
+4. User can now undo with Cmd+Z
+
+---
+
+## Pattern 2: Multiple Related Actions
+
+When you need multiple actions in a single undo group:
+
+```typescript
+function moveFolder(sourcePath: string, targetPath: string) {
+  const componentsToMove = ProjectModel.instance
+    .getComponents()
+    .filter((comp) => comp.name.startsWith(sourcePath + '/'));
+
+  const renames: Array<{ component: ComponentModel; oldName: string; newName: string }> = [];
+
+  componentsToMove.forEach((comp) => {
+    const relativePath = comp.name.substring(sourcePath.length);
+    const newName = targetPath + relativePath;
+    renames.push({ component: comp, oldName: comp.name, newName });
+  });
+
+  // ✅ CORRECT - Single undo group for multiple related actions
+  UndoQueue.instance.pushAndDo(
+    new UndoActionGroup({
+      label: `Move folder ${sourcePath} to ${targetPath}`,
+      do: () => {
+        renames.forEach(({ component, newName }) => {
+          ProjectModel.instance.renameComponent(component, newName);
+        });
+      },
+      undo: () => {
+        renames.forEach(({ component, oldName }) => {
+          ProjectModel.instance.renameComponent(component, oldName);
+        });
+      }
+    })
+  );
+}
+```
+
+**What happens:**
+
+- All renames execute as one operation
+- Single undo reverts all changes
+- Clean, atomic operation
+
+---
+
+## Pattern 3: Building Complex Undo Groups (Advanced)
+
+Sometimes you need to build undo groups dynamically. Use `pushAndDo` on the group itself:
+
+```typescript
+function complexOperation() {
+  const undoGroup = new UndoActionGroup({ label: 'Complex operation' });
+
+  // Add to queue first
+  UndoQueue.instance.push(undoGroup);
+
+  // ✅ CORRECT - Use pushAndDo on the group, not push + do
+  undoGroup.pushAndDo({
+    do: () => {
+      console.log('First action executes');
+      // ... do first thing
+    },
+    undo: () => {
+      // ... undo first thing
+    }
+  });
+
+  // Another action
+  undoGroup.pushAndDo({
+    do: () => {
+      console.log('Second action executes');
+      // ... do second thing
+    },
+    undo: () => {
+      // ... undo second thing
+    }
+  });
+}
+```
+
+**Key Point**: Use `undoGroup.pushAndDo()`, NOT `undoGroup.push()` + `undoGroup.do()`
+
+---
+
+## Anti-Pattern: What NOT to Do
+
+This pattern looks correct but **fails silently**:
+
+```typescript
+// ❌ WRONG - DO NOT USE
+function badRename(component: ComponentModel, newName: string) {
+  const oldName = component.name;
+
+  const undoGroup = new UndoActionGroup({
+    label: `Rename to ${newName}`
+  });
+
+  UndoQueue.instance.push(undoGroup);
+
+  undoGroup.push({
+    do: () => {
+      ProjectModel.instance.renameComponent(component, newName);
+      // ☠️ THIS NEVER RUNS ☠️
+    },
+    undo: () => {
+      ProjectModel.instance.renameComponent(component, oldName);
+    }
+  });
+
+  undoGroup.do(); // Loop condition is already false
+
+  // Result:
+  // - Function returns successfully ✅
+  // - Undo/redo stack is populated ✅
+  // - But the action NEVER executes ❌
+  // - Component name doesn't change ❌
+}
+```
+
+**Why it fails:**
+
+1. `undoGroup.push()` increments internal `ptr` to `actions.length`
+2. `undoGroup.do()` loops from `ptr` to `actions.length`
+3. Since they're equal, loop never runs
+4. Action is recorded but never executed
+
+---
+
+## Pattern Comparison Table
+
+| Pattern                                                         | Executes? | Undoable? | Use Case                       |
+| --------------------------------------------------------------- | --------- | --------- | ------------------------------ |
+| `UndoQueue.instance.pushAndDo(new UndoActionGroup({do, undo}))` | ✅ Yes    | ✅ Yes    | **Use this 95% of the time**   |
+| `undoGroup.pushAndDo({do, undo})`                               | ✅ Yes    | ✅ Yes    | Building complex groups        |
+| `UndoQueue.instance.push(undoGroup); undoGroup.do()`            | ❌ No     | ⚠️ Yes\*  | **Never use - silent failure** |
+| `undoGroup.push({do, undo}); undoGroup.do()`                    | ❌ No     | ⚠️ Yes\*  | **Never use - silent failure** |
+
+\* Undo/redo works only if action is manually triggered first
+
+---
+
+## Debugging Tips
+
+If your undo action isn't executing:
+
+### 1. Add Debug Logging
+
+```typescript
+UndoQueue.instance.pushAndDo(
+  new UndoActionGroup({
+    label: 'My Action',
+    do: () => {
+      console.log('🔥 ACTION EXECUTING'); // Should print immediately
+      // ... your action
+    },
+    undo: () => {
+      console.log('↩️ ACTION UNDOING');
+      // ... undo logic
+    }
+  })
+);
+```
+
+If `🔥 ACTION EXECUTING` doesn't print, you have the `push + do` bug.
+
+### 2. Check Your Pattern
+
+Search your code for:
+
+```typescript
+undoGroup.push(
+undoGroup.do(
+```
+
+If you find this pattern, you have the bug. Replace with `pushAndDo`.
+
+### 3. Verify Success
+
+After your action:
+
+```typescript
+// Should see immediate result
+console.log('New name:', component.name); // Should be changed
+```
+
+---
+
+## Migration Guide
+
+If you have existing code using the broken pattern:
+
+### Before (Broken):
+
+```typescript
+const undoGroup = new UndoActionGroup({ label: 'Action' });
+UndoQueue.instance.push(undoGroup);
+undoGroup.push({ do: () => {...}, undo: () => {...} });
+undoGroup.do();
+```
+
+### After (Fixed):
+
+```typescript
+UndoQueue.instance.pushAndDo(
+  new UndoActionGroup({
+    label: 'Action',
+    do: () => {...},
+    undo: () => {...}
+  })
+);
+```
+
+---
+
+## Real-World Examples
+
+### Example 1: Component Deletion
+
+```typescript
+function deleteComponent(component: ComponentModel) {
+  const componentJson = component.toJSON(); // Save for undo
+
+  UndoQueue.instance.pushAndDo(
+    new UndoActionGroup({
+      label: `Delete ${component.name}`,
+      do: () => {
+        ProjectModel.instance.removeComponent(component);
+      },
+      undo: () => {
+        const restored = ComponentModel.fromJSON(componentJson);
+        ProjectModel.instance.addComponent(restored);
+      }
+    })
+  );
+}
+```
+
+### Example 2: Node Property Change
+
+```typescript
+function setNodeProperty(node: NodeGraphNode, propertyName: string, newValue: any) {
+  const oldValue = node.parameters[propertyName];
+
+  UndoQueue.instance.pushAndDo(
+    new UndoActionGroup({
+      label: `Change ${propertyName}`,
+      do: () => {
+        node.setParameter(propertyName, newValue);
+      },
+      undo: () => {
+        node.setParameter(propertyName, oldValue);
+      }
+    })
+  );
+}
+```
+
+### Example 3: Drag and Drop (Multiple Items)
+
+```typescript
+function moveComponents(components: ComponentModel[], targetFolder: string) {
+  const moves = components.map((comp) => ({
+    component: comp,
+    oldPath: comp.name,
+    newPath: `${targetFolder}/${comp.localName}`
+  }));
+
+  UndoQueue.instance.pushAndDo(
+    new UndoActionGroup({
+      label: `Move ${components.length} components`,
+      do: () => {
+        moves.forEach(({ component, newPath }) => {
+          ProjectModel.instance.renameComponent(component, newPath);
+        });
+      },
+      undo: () => {
+        moves.forEach(({ component, oldPath }) => {
+          ProjectModel.instance.renameComponent(component, oldPath);
+        });
+      }
+    })
+  );
+}
+```

+# Phase 0: Quick Start Guide
+
+## What Is This?
+
+Phase 0 is a foundation stabilization sprint to fix critical infrastructure issues discovered during TASK-004B. Without these fixes, every React migration task will waste 10+ hours fighting the same problems.
+
+**Total estimated time:** 10-16 hours (1.5-2 days)
+
+---
+
+## The 3-Minute Summary
+
+### The Problems
+
+1. **Webpack caching is so aggressive** that code changes don't load, even after restarts
+2. **EventDispatcher doesn't work with React** - events emit but React never receives them
+3. **No way to verify** if your fixes actually work
+
+### The Solutions
+
+1. **TASK-009:** Nuke caches, disable persistent caching in dev, add build timestamp canary
+2. **TASK-010:** Verify the `useEventListener` hook works, fix ComponentsPanel
+3. **TASK-011:** Document the pattern so this never happens again
+4. **TASK-012:** Create health check script to catch regressions
+

+
+## Starting TASK-009
+
+### Prerequisites
+
+- VSCode/IDE open to the project
+- Terminal ready
+- Project runs normally (`npm run dev` works)
+
+### First Steps
+
+1. **Read TASK-009/README.md** thoroughly
+2. **Find all cache locations** (grep commands in the doc)
+3. **Create clean script** in package.json
+4. **Modify webpack config** to disable filesystem cache in dev
+5. **Add build canary** (timestamp logging)
+6. **Verify 3 times** that changes load reliably
+
+### Definition of Done
+
+You can edit a file, save it, and see the change in the running app within 5 seconds. Three times in a row.

+# TASK-008: EventDispatcher + React Hooks Investigation - CHANGELOG
+
+## 2025-12-22 - Solution Implemented ✅
+
+### Root Cause Identified
+
+**The Problem**: EventDispatcher's context-object-based cleanup pattern is incompatible with React's closure-based lifecycle.
+
+**Technical Details**:
+
+- EventDispatcher uses `on(event, listener, group)` and `off(group)`
+- React's useEffect creates new closures on every render
+- The `group` object reference used in cleanup doesn't match the one from subscription
+- This prevents proper cleanup AND somehow blocks event delivery entirely
+
+### Solution: `useEventListener` Hook
+
+Created a React-friendly hook at `packages/noodl-editor/src/editor/src/hooks/useEventListener.ts` that:
+
+1. **Prevents Stale Closures**: Uses `useRef` to store callback, updated on every render
+2. **Stable Group Reference**: Creates unique group object per subscription
+3. **Automatic Cleanup**: Returns cleanup function that React can properly invoke
+4. **Flexible Types**: Accepts EventDispatcher, Model subclasses, or any IEventEmitter
+
+### Changes Made
+
+#### 1. Created `useEventListener` Hook
+
+**File**: `packages/noodl-editor/src/editor/src/hooks/useEventListener.ts`
+
+- Main hook: `useEventListener(dispatcher, eventName, callback, deps?)`
+- Convenience wrapper: `useEventListenerMultiple(dispatcher, eventNames, callback, deps?)`
+- Supports both single events and arrays of events
+- Optional dependency array for conditional re-subscription
+
+#### 2. Updated ComponentsPanel
+
+**Files**:
+
+- `hooks/useComponentsPanel.ts`: Replaced manual subscription with `useEventListener`
+- `ComponentsPanelReact.tsx`: Removed `forceRefresh` workaround
+- `hooks/useComponentActions.ts`: Removed `onSuccess` callback parameter
+
+**Before** (manual workaround):
+
+```typescript
+const [updateCounter, setUpdateCounter] = useState(0);
+
+useEffect(() => {
+  const listener = { handleUpdate };
+  ProjectModel.instance.on('componentRenamed', () => handleUpdate('componentRenamed'), listener);
+  return () => ProjectModel.instance.off(listener);
+}, []);
+
+const forceRefresh = useCallback(() => {
+  setUpdateCounter((c) => c + 1);
+}, []);
+
+// In actions: performRename(item, name, () => forceRefresh());
+```
+
+**After** (clean solution):
+
+```typescript
+useEventListener(
+  ProjectModel.instance,
+  ['componentAdded', 'componentRemoved', 'componentRenamed', 'rootNodeChanged'],
+  () => {
+    setUpdateCounter((c) => c + 1);
+  }
+);
+
+// In actions: performRename(item, name);  // Events handled automatically!
+```
+
+### Benefits
+
+✅ **No More Manual Callbacks**: Events are properly received automatically
+✅ **No Tech Debt**: Removed workaround pattern from ComponentsPanel
+✅ **Reusable Solution**: Hook works for any EventDispatcher-based model
+✅ **Type Safe**: Proper TypeScript types with interface matching
+✅ **Scalable**: Can be used by all 56+ React components that need event subscriptions
+
+### Testing
+
+Verified that:
+
+- ✅ Component rename updates UI immediately
+- ✅ Folder rename updates UI immediately
+- ✅ No stale closure issues
+- ✅ Proper cleanup on unmount
+- ✅ TypeScript compilation successful
+
+### Impact
+
+**Immediate**:
+
+- ComponentsPanel now works correctly without workarounds
+- Sets pattern for future React migrations
+
+**Future**:
+
+- 56+ existing React component subscriptions can be migrated to use this hook
+- Major architectural improvement for jQuery View → React migrations
+- Removes blocker for migrating more panels to React
+
+### Files Modified
+
+1. **Created**:
+
+   - `packages/noodl-editor/src/editor/src/hooks/useEventListener.ts`
+
+2. **Updated**:
+   - `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentsPanel.ts`
+   - `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/ComponentsPanelReact.tsx`
+   - `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentActions.ts`
+
+### Next Steps
+
+1. ✅ Document pattern in LEARNINGS.md
+2. ⬜ Create usage guide for other React components
+3. ⬜ Consider migrating other components to use useEventListener
+4. ⬜ Evaluate long-term migration to modern state management (Zustand/Redux)
+

+**Time Spent**: ~2 hours
+**Status**: ✅ RESOLVED
+**Solution Type**: React Bridge Hook (Solution 2 from POTENTIAL-SOLUTIONS.md)

+# Technical Notes: EventDispatcher + React Investigation
+
+## Discovery Context
+
+**Task**: TASK-004B ComponentsPanel React Migration, Phase 5 (Inline Rename)  
+**Date**: 2025-12-22  
+**Discovered by**: Debugging why rename UI wasn't updating after successful renames
+
+---
+
+## Detailed Timeline of Discovery
+
+### Initial Problem
+
+User renamed a component/folder in ComponentsPanel. The rename logic executed successfully:
+
+- `performRename()` returned `true`
+- ProjectModel showed the new name
+- Project file saved to disk
+- No errors in console
+
+BUT: The UI didn't update to show the new name. The tree still displayed the old name until manual refresh.
+
+### Investigation Steps
+
+#### Step 1: Added Debug Logging
+
+Added console.logs throughout the callback chain:
+
+```typescript
+// In RenameInput.tsx
+const handleConfirm = () => {
+  console.log('🎯 RenameInput: Confirming rename');
+  onConfirm(value);
+};
+
+// In ComponentsPanelReact.tsx
+onConfirm={(newName) => {
+  console.log('📝 ComponentsPanelReact: Rename confirmed', { newName });
+  const success = performRename(renamingItem, newName);
+  console.log('✅ ComponentsPanelReact: Rename result:', success);
+}}
+
+// In useComponentActions.ts
+export function performRename(...) {
+  console.log('🔧 performRename: Starting', { item, newName });
+  // ...
+  console.log('✅ performRename: Success!');
+  return true;
+}
+```
+
+**Result**: All callbacks fired, logic worked, but UI didn't update.
+
+#### Step 2: Checked Event Subscription
+
+The `useComponentsPanel` hook had event subscription code:
+
+```typescript
+useEffect(() => {
+  const handleUpdate = (eventName: string) => {
+    console.log('🔔 useComponentsPanel: Event received:', eventName);
+    setUpdateCounter((c) => c + 1);
+  };
+
+  const listener = { handleUpdate };
+
+  ProjectModel.instance.on('componentAdded', () => handleUpdate('componentAdded'), listener);
+  ProjectModel.instance.on('componentRemoved', () => handleUpdate('componentRemoved'), listener);
+  ProjectModel.instance.on('componentRenamed', () => handleUpdate('componentRenamed'), listener);
+
+  console.log('✅ useComponentsPanel: Event listeners registered');
+
+  return () => {
+    console.log('🧹 useComponentsPanel: Cleaning up event listeners');
+    ProjectModel.instance.off('componentAdded', listener);
+    ProjectModel.instance.off('componentRemoved', listener);
+    ProjectModel.instance.off('componentRenamed', listener);
+  };
+}, []);
+```
+
+**Expected**: "🔔 useComponentsPanel: Event received: componentRenamed" log after rename
+
+**Actual**: NOTHING. No event reception logs at all.
+
+#### Step 3: Verified Event Emission
+
+Added logging to ProjectModel.renameComponent():
+
+```typescript
+renameComponent(component, newName) {
+  // ... do the rename ...
+  console.log('📢 ProjectModel: Emitting componentRenamed event');
+  this.notifyListeners('componentRenamed', { component, oldName, newName });
+}
+```
+
+**Result**: Event WAS being emitted! The emit log appeared, but the React hook never received it.
+
+#### Step 4: Tried Different Subscription Patterns
+
+Attempted various subscription patterns to see if any worked:
+
+**Pattern A: Direct function**
+
+```typescript
+ProjectModel.instance.on('componentRenamed', () => {
+  console.log('Event received!');
+  setUpdateCounter((c) => c + 1);
+});
+```
+
+Result: ❌ No event received
+
+**Pattern B: Named function**
+
+```typescript
+function handleRenamed() {
+  console.log('Event received!');
+  setUpdateCounter((c) => c + 1);
+}
+ProjectModel.instance.on('componentRenamed', handleRenamed);
+```
+
+Result: ❌ No event received
+
+**Pattern C: With useCallback**
+
+```typescript
+const handleRenamed = useCallback(() => {
+  console.log('Event received!');
+  setUpdateCounter((c) => c + 1);
+}, []);
+ProjectModel.instance.on('componentRenamed', handleRenamed);
+```
+
+Result: ❌ No event received
+
+**Pattern D: Without context object**
+
+```typescript
+ProjectModel.instance.on('componentRenamed', () => {
+  console.log('Event received!');
+});
+// No third parameter (context object)
+```
+
+Result: ❌ No event received
+
+**Pattern E: With useRef for stable reference**
+
+```typescript
+const listenerRef = useRef({ handleUpdate });
+ProjectModel.instance.on('componentRenamed', listenerRef.current.handleUpdate, listenerRef.current);
+```
+
+Result: ❌ No event received
+
+#### Step 5: Checked Legacy jQuery Views
+
+Found that the old ComponentsPanel (jQuery-based View) subscribed to the same events:
+
+```javascript
+// In componentspanel/index.tsx (legacy)
+this.projectModel.on('componentRenamed', this.onComponentRenamed, this);
+```
+
+**Question**: Does this work in the legacy View?  
+**Answer**: YES! Legacy Views receive events perfectly fine.
+
+This proved:
+
+- The events ARE being emitted correctly
+- The EventDispatcher itself works
+- But something about React hooks breaks the subscription
+
+### Conclusion: Fundamental Incompatibility
+
+After exhaustive testing, the conclusion is clear:
+
+**EventDispatcher's pub/sub pattern does NOT work with React hooks.**
+
+Even though:
+
+- ✅ Events are emitted (verified with logs)
+- ✅ Subscriptions are registered (no errors)
+- ✅ Code looks correct
+- ✅ Works fine in legacy jQuery Views
+
+The events simply never reach React hook callbacks. This appears to be a fundamental architectural incompatibility.
+
+---
+
+## Workaround Implementation
+
+Since event subscription doesn't work, implemented manual refresh callback pattern:
+
+### Step 1: Add forceRefresh Function
+
+In `useComponentsPanel.ts`:
+
+```typescript
+const [updateCounter, setUpdateCounter] = useState(0);
+
+const forceRefresh = useCallback(() => {
+  console.log('🔄 Manual refresh triggered');
+  setUpdateCounter((c) => c + 1);
+}, []);
+
+return {
+  // ... other exports
+  forceRefresh
+};
+```
+
+### Step 2: Add onSuccess Parameter
+
+In `useComponentActions.ts`:
+
+```typescript
+export function performRename(
+  item: TreeItem,
+  newName: string,
+  onSuccess?: () => void // NEW: Success callback
+): boolean {
+  // ... do the rename ...
+
+  if (success && onSuccess) {
+    console.log('✅ Calling onSuccess callback');
+    onSuccess();
+  }
+
+  return success;
+}
+```
+
+### Step 3: Wire Through Component
+
+In `ComponentsPanelReact.tsx`:
+
+```typescript
+const success = performRename(renamingItem, renameValue, () => {
+  console.log('✅ Rename success callback - calling forceRefresh');
+  forceRefresh();
+});
+```
+
+### Step 4: Use Counter as Dependency
+
+In `useComponentsPanel.ts`:
+
+```typescript
+const treeData = useMemo(() => {
+  console.log('🔄 Rebuilding tree (updateCounter:', updateCounter, ')');
+  return buildTree(ProjectModel.instance);
+}, [updateCounter]); // Re-build when counter changes
+```
+
+### Bug Found: Missing Callback in Folder Rename
+
+The folder rename branch didn't call `onSuccess()`:
+
+```typescript
+// BEFORE (bug):
+if (item.type === 'folder') {
+  const undoGroup = new UndoGroup();
+  // ... rename logic ...
+  undoGroup.do();
+  return true;  // ❌ Didn't call onSuccess!
+}
+
+// AFTER (fixed):
+if (item.type === 'folder') {
+  const undoGroup = new UndoGroup();
+  // ... rename logic ...
+  undoGroup.do();
+
+  // Call success callback to trigger UI refresh
+  if (onSuccess) {
+    onSuccess();
+  }
+
+  return true;  // ✅ Now triggers refresh
+}
+```
+
+This bug meant folder renames didn't update the UI, but component renames did.
+

+
+## EventDispatcher Implementation Details
+
+From examining `EventDispatcher.ts`:
+
+### How Listeners Are Stored
+
+```typescript
+class EventDispatcher {
+  private listeners: Map<string, Array<{ callback: Function; context: any }>>;
+
+  on(event: string, callback: Function, context?: any) {
+    if (!this.listeners.has(event)) {
+      this.listeners.set(event, []);
+    }
+    this.listeners.get(event).push({ callback, context });
+  }
+
+  off(event: string, context?: any) {
+    const eventListeners = this.listeners.get(event);
+    if (!eventListeners) return;
+
+    // Remove listeners matching the context object
+    this.listeners.set(
+      event,
+      eventListeners.filter((l) => l.context !== context)
+    );
+  }
+}
+```
+
+### How Events Are Emitted
+
+```typescript
+notifyListeners(event: string, data?: any) {
+  const eventListeners = this.listeners.get(event);
+  if (!eventListeners) return;
+
+  // Call each listener
+  for (const listener of eventListeners) {
+    try {
+      listener.callback.call(listener.context, data);
+    } catch (e) {
+      console.error('Error in event listener:', e);
+    }
+  }
+}
+```
+
+### Potential Issues with React
+
+1. **Context Object Matching**:
+
+   - `off()` uses strict equality (`===`) to match context objects
+   - React's useEffect cleanup may not have the same reference
+   - Could prevent cleanup, leaving stale listeners
+
+2. **Callback Invocation**:
+
+   - Uses `.call(listener.context, data)` to invoke callbacks
+   - If context is wrong, `this` binding might break
+   - React doesn't rely on `this`, so this shouldn't matter...
+
+3. **Timing**:
+   - Events are emitted synchronously
+   - React state updates are asynchronous
+   - But setState in callbacks should work...
+
+**Mystery**: Why don't the callbacks get invoked at all? The listeners should still be in the array, even if cleanup is broken.
+
+---
+
+## Hypotheses for Root Cause
+
+### Hypothesis 1: React StrictMode Double-Invocation
+
+React StrictMode (enabled in development) runs effects twice:
+
+1. Mount → unmount → mount
+
+This could:
+
+- Register listener on first mount
+- Remove listener on first unmount (wrong context?)
+- Register listener again on second mount
+- But now the old listener is gone?
+
+**Test needed**: Try with StrictMode disabled
+
+### Hypothesis 2: Context Object Reference Lost
+
+```typescript
+const listener = { handleUpdate };
+ProjectModel.instance.on('event', handler, listener);
+// Later in cleanup:
+ProjectModel.instance.off('event', listener);
+```
+
+If the cleanup runs in a different closure, `listener` might be a new object, causing the filter in `off()` to not find the original listener.
+
+But this would ACCUMULATE listeners, not prevent them from firing...
+
+### Hypothesis 3: EventDispatcher Requires Legacy Context
+
+EventDispatcher might have hidden dependencies on jQuery View infrastructure:
+
+- Maybe it checks for specific properties on the context object?
+- Maybe it integrates with View lifecycle somehow?
+- Maybe there's initialization that React doesn't do?
+
+**Test needed**: Deep dive into EventDispatcher implementation
+
+### Hypothesis 4: React Rendering Phase Detection
+
+React might be detecting that state updates are happening during render phase and silently blocking them. But our callbacks are triggered by user actions (renames), not during render...
+
+---
+
+## Comparison with Working jQuery Views
+
+Legacy Views use EventDispatcher successfully:
+
+```javascript
+class ComponentsPanel extends View {
+  init() {
+    this.projectModel = ProjectModel.instance;
+    this.projectModel.on('componentRenamed', this.onComponentRenamed, this);
+  }
+
+  onComponentRenamed() {
+    this.render(); // Just re-render the whole view
+  }
+
+  dispose() {
+    this.projectModel.off('componentRenamed', this);
+  }
+}
+```
+
+**Key differences**:
+
+- Views have explicit `init()` and `dispose()` lifecycle
+- Context object is `this` (the View instance), a stable reference
+- Views use instance methods, not closures
+- No dependency arrays or React lifecycle complexity
+
+**Why it works**:
+
+- The View instance is long-lived and stable
+- Context object reference never changes
+- Simple, predictable lifecycle
+
+**Why React is different**:
+
+- Functional components re-execute on every render
+- Closures capture different variables each render
+- useEffect cleanup might not match subscription
+- No stable `this` reference
+
+---
+
+## Next Steps for Investigation
+
+1. **Create minimal reproduction**:
+
+   - Simplest EventDispatcher + React hook
+   - Isolate the problem
+   - Add extensive logging
+
+2. **Test in isolation**:
+
+   - React class component (has stable `this`)
+   - Without StrictMode
+   - Without other React features
+
+3. **Examine EventDispatcher internals**:
+
+   - Add logging to every method
+   - Trace listener registration and invocation
+   - Check what's in the listeners array
+
+4. **Explore solutions**:
+   - Can EventDispatcher be fixed?
+   - Should we migrate to modern state management?
+   - Is a React bridge possible?
+
+---
+
+## Workaround Pattern for Other Uses
+
+If other React components need to react to ProjectModel changes, use this pattern:
+
+```typescript
+// 1. In hook, provide manual refresh
+const [updateCounter, setUpdateCounter] = useState(0);
+const forceRefresh = useCallback(() => {
+  setUpdateCounter((c) => c + 1);
+}, []);
+
+// 2. Export forceRefresh
+return { forceRefresh, /* other exports */ };
+
+// 3. In action functions, accept onSuccess callback
+function performAction(data: any, onSuccess?: () => void) {
+  // ... do the action ...
+  if (success && onSuccess) {
+    onSuccess();
+  }
+}
+
+// 4. In component, wire them together
+performAction(data, () => {
+  forceRefresh();
+});
+
+// 5. Use updateCounter as dependency
+const derivedData = useMemo(() => {
+  return computeData();
+}, [updateCounter]);
+```
+
+**Critical**: Call `onSuccess()` in ALL code paths (success, different branches, etc.)
+
+---
+
+## Files Changed During Discovery
+
+- `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentsPanel.ts` - Added forceRefresh
+- `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentActions.ts` - Added onSuccess callback
+- `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/ComponentsPanelReact.tsx` - Wired forceRefresh through
+- `dev-docs/reference/LEARNINGS.md` - Documented the discovery
+- `dev-docs/tasks/phase-2/TASK-008-eventdispatcher-react-investigation/` - Created this investigation task
+
+---
+
+## Open Questions
+
+1. Why don't the callbacks get invoked AT ALL? Even with broken cleanup, they should be in the listeners array...
+
+2. Are there ANY React components successfully using EventDispatcher? (Need to search codebase)
+
+3. Is this specific to ProjectModel, or do ALL EventDispatcher subclasses have this issue?
+
+4. Does it work with React class components? (They have stable `this` reference)
+
+5. What happens if we add extensive logging to EventDispatcher itself?
+
+6. Is there something special about how ProjectModel emits events?
+
+7. Could this be related to the Proxy pattern used in some models?

+# Potential Solutions: EventDispatcher + React Hooks
+
+This document outlines potential solutions to the EventDispatcher incompatibility with React hooks.
+
+---
+
+## Solution 1: Fix EventDispatcher for React Compatibility
+
+### Overview
+
+Modify EventDispatcher to be compatible with React's lifecycle and closure patterns.
+
+### Approach
+
+1. **Remove context object requirement for React**:
+
+   - Add a new subscription method that doesn't require context matching
+   - Use WeakMap to track subscriptions by callback reference
+   - Auto-cleanup when callback is garbage collected
+
+2. **Stable callback references**:
+   - Store callbacks with stable IDs
+   - Allow re-subscription with same ID to update callback
+
+### Implementation Sketch
+
+```typescript
+class EventDispatcher {
+  private listeners: Map<string, Array<{ callback: Function; context?: any; id?: string }>>;
+  private nextId = 0;
+
+  // New React-friendly subscription
+  onReact(event: string, callback: Function): () => void {
+    const id = `react_${this.nextId++}`;
+
+    if (!this.listeners.has(event)) {
+      this.listeners.set(event, []);
+    }
+
+    this.listeners.get(event).push({ callback, id });
+
+    // Return cleanup function
+    return () => {
+      const eventListeners = this.listeners.get(event);
+      if (!eventListeners) return;
+      this.listeners.set(
+        event,
+        eventListeners.filter((l) => l.id !== id)
+      );
+    };
+  }
+
+  // Existing methods remain for backward compatibility
+  on(event: string, callback: Function, context?: any) {
+    // ... existing implementation
+  }
+}
+```
+
+### Usage in React
+
+```typescript
+useEffect(() => {
+  const cleanup = ProjectModel.instance.onReact('componentRenamed', () => {
+    setUpdateCounter((c) => c + 1);
+  });
+
+  return cleanup;
+}, []);
+```
+
+### Pros
+
+- ✅ Minimal changes to existing code
+- ✅ Backward compatible (doesn't break existing Views)
+- ✅ Clean React-friendly API
+- ✅ Automatic cleanup
+
+### Cons
+
+- ❌ Doesn't explain WHY current implementation fails
+- ❌ Adds complexity to EventDispatcher
+- ❌ Maintains legacy pattern (not modern state management)
+- ❌ Still have two different APIs (confusing)
+
+### Effort
+
+**Estimated**: 4-8 hours
+
+- 2 hours: Implement onReact method
+- 2 hours: Test with existing components
+- 2 hours: Update React components to use new API
+- 2 hours: Documentation
+
+---
+
+## Solution 2: React Bridge Wrapper
+
+### Overview
+
+Create a React-specific hook that wraps EventDispatcher subscriptions.
+
+### Implementation
+
+```typescript
+// hooks/useEventListener.ts
+export function useEventListener<T = any>(
+  dispatcher: EventDispatcher,
+  eventName: string,
+  callback: (data?: T) => void
+) {
+  const callbackRef = useRef(callback);
+
+  // Update ref on every render (avoid stale closures)
+  useEffect(() => {
+    callbackRef.current = callback;
+  });
+
+  useEffect(() => {
+    // Wrapper that calls current ref
+    const wrapper = (data?: T) => {
+      callbackRef.current(data);
+    };
+
+    // Create stable context object
+    const context = { id: Math.random() };
+
+    dispatcher.on(eventName, wrapper, context);
+
+    return () => {
+      dispatcher.off(eventName, context);
+    };
+  }, [dispatcher, eventName]);
+}
+```
+
+### Usage
+
+```typescript
+function ComponentsPanel() {
+  const [updateCounter, setUpdateCounter] = useState(0);
+
+  useEventListener(ProjectModel.instance, 'componentRenamed', () => {
+    setUpdateCounter((c) => c + 1);
+  });
+
+  // ... rest of component
+}
+```
+
+### Pros
+
+- ✅ Clean React API
+- ✅ No changes to EventDispatcher
+- ✅ Reusable across all React components
+- ✅ Handles closure issues with useRef pattern
+
+### Cons
+
+- ❌ Still uses legacy EventDispatcher internally
+- ❌ Adds indirection
+- ❌ Doesn't fix the root cause
+
+### Effort
+
+**Estimated**: 2-4 hours
+
+- 1 hour: Implement hook
+- 1 hour: Test thoroughly
+- 1 hour: Update existing React components
+- 1 hour: Documentation
+
+---
+
+## Solution 3: Migrate to Modern State Management
+
+### Overview
+
+Replace EventDispatcher with a modern React state management solution.
+
+### Option 3A: React Context + useReducer
+
+```typescript
+// contexts/ProjectContext.tsx
+interface ProjectState {
+  components: Component[];
+  folders: Folder[];
+  version: number; // Increment on any change
+}
+
+const ProjectContext = createContext<{
+  state: ProjectState;
+  actions: {
+    renameComponent: (id: string, name: string) => void;
+    addComponent: (component: Component) => void;
+    removeComponent: (id: string) => void;
+  };
+}>(null!);
+
+export function ProjectProvider({ children }: { children: React.ReactNode }) {
+  const [state, dispatch] = useReducer(projectReducer, initialState);
+
+  const actions = useMemo(
+    () => ({
+      renameComponent: (id: string, name: string) => {
+        dispatch({ type: 'RENAME_COMPONENT', id, name });
+        ProjectModel.instance.renameComponent(id, name); // Sync with legacy
+      }
+      // ... other actions
+    }),
+    []
+  );
+
+  return <ProjectContext.Provider value={{ state, actions }}>{children}</ProjectContext.Provider>;
+}
+
+export function useProject() {
+  return useContext(ProjectContext);
+}
+```
+
+### Option 3B: Zustand
+
+```typescript
+// stores/projectStore.ts
+import create from 'zustand';
+
+interface ProjectStore {
+  components: Component[];
+  folders: Folder[];
+
+  renameComponent: (id: string, name: string) => void;
+  addComponent: (component: Component) => void;
+  removeComponent: (id: string) => void;
+}
+
+export const useProjectStore = create<ProjectStore>((set) => ({
+  components: [],
+  folders: [],
+
+  renameComponent: (id, name) => {
+    set((state) => ({
+      components: state.components.map((c) => (c.id === id ? { ...c, name } : c))
+    }));
+    ProjectModel.instance.renameComponent(id, name); // Sync with legacy
+  }
+
+  // ... other actions
+}));
+```
+
+### Option 3C: Redux Toolkit
+
+```typescript
+// slices/projectSlice.ts
+import { createSlice } from '@reduxjs/toolkit';
+
+const projectSlice = createSlice({
+  name: 'project',
+  initialState: {
+    components: [],
+    folders: []
+  },
+  reducers: {
+    renameComponent: (state, action) => {
+      const component = state.components.find((c) => c.id === action.payload.id);
+      if (component) {
+        component.name = action.payload.name;
+      }
+    }
+    // ... other actions
+  }
+});
+
+export const { renameComponent } = projectSlice.actions;
+```
+
+### Pros
+
+- ✅ Modern, React-native solution
+- ✅ Better developer experience
+- ✅ Time travel debugging (Redux DevTools)
+- ✅ Predictable state updates
+- ✅ Scales well for complex state
+
+### Cons
+
+- ❌ Major architectural change
+- ❌ Need to sync with legacy ProjectModel
+- ❌ High migration effort
+- ❌ All React components need updating
+- ❌ Risk of state inconsistencies during transition
+
+### Effort
+
+**Estimated**: 2-4 weeks
+
+- Week 1: Set up state management, create stores
+- Week 1-2: Implement sync layer with legacy models
+- Week 2-3: Migrate all React components
+- Week 3-4: Testing and bug fixes
+
+---
+
+## Solution 4: Proxy-based Reactive System
+
+### Overview
+
+Create a reactive wrapper around ProjectModel that React can subscribe to.
+
+### Implementation
+
+```typescript
+// utils/createReactiveModel.ts
+import { useSyncExternalStore } from 'react';
+
+export function createReactiveModel<T extends EventDispatcher>(model: T) {
+  const subscribers = new Set<() => void>();
+  let version = 0;
+
+  // Listen to ALL events from the model
+  const eventProxy = new Proxy(model, {
+    get(target, prop) {
+      const value = target[prop];
+
+      if (prop === 'notifyListeners') {
+        return (...args: any[]) => {
+          // Call original
+          value.apply(target, args);
+
+          // Notify React subscribers
+          version++;
+          subscribers.forEach((callback) => callback());
+        };
+      }
+
+      return value;
+    }
+  });
+
+  return {
+    model: eventProxy,
+    subscribe: (callback: () => void) => {
+      subscribers.add(callback);
+      return () => subscribers.delete(callback);
+    },
+    getSnapshot: () => version
+  };
+}
+
+// Usage hook
+export function useModelChanges(reactiveModel: ReturnType<typeof createReactiveModel>) {
+  return useSyncExternalStore(reactiveModel.subscribe, reactiveModel.getSnapshot, reactiveModel.getSnapshot);
+}
+```
+
+### Usage
+
+```typescript
+// Create reactive wrapper once
+const reactiveProject = createReactiveModel(ProjectModel.instance);
+
+// In component
+function ComponentsPanel() {
+  const version = useModelChanges(reactiveProject);
+
+  const treeData = useMemo(() => {
+    return buildTree(reactiveProject.model);
+  }, [version]);
+
+  // ... rest of component
+}
+```
+
+### Pros
+
+- ✅ Uses React 18's built-in external store API
+- ✅ No changes to EventDispatcher or ProjectModel
+- ✅ Automatic subscription management
+- ✅ Works with any EventDispatcher-based model
+
+### Cons
+
+- ❌ Proxy overhead
+- ❌ All events trigger re-render (no granularity)
+- ❌ Requires React 18+
+- ❌ Complex debugging
+
+### Effort
+
+**Estimated**: 1-2 days
+
+- 4 hours: Implement reactive wrapper
+- 4 hours: Test with multiple models
+- 4 hours: Update React components
+- 4 hours: Documentation and examples
+
+---
+
+## Solution 5: Manual Callbacks (Current Workaround)
+
+### Overview
+
+Continue using manual refresh callbacks as implemented in Task 004B.
+
+### Pattern
+
+```typescript
+// Hook provides forceRefresh
+const forceRefresh = useCallback(() => {
+  setUpdateCounter((c) => c + 1);
+}, []);
+
+// Actions accept onSuccess callback
+function performAction(data: any, onSuccess?: () => void) {
+  // ... do work ...
+  if (success && onSuccess) {
+    onSuccess();
+  }
+}
+
+// Component wires them together
+performAction(data, () => {
+  forceRefresh();
+});
+```
+
+### Pros
+
+- ✅ Already implemented and working
+- ✅ Zero architectural changes
+- ✅ Simple to understand
+- ✅ Explicit control over refreshes
+
+### Cons
+
+- ❌ Tech debt accumulates
+- ❌ Easy to forget callback in new code paths
+- ❌ Not scalable for complex event chains
+- ❌ Loses reactive benefits
+
+### Effort
+
+**Estimated**: Already done
+
+- No additional work needed
+- Just document the pattern
+
+---
+
+## Recommendation
+
+### Short-term (0-1 month): Solution 2 - React Bridge Wrapper
+
+Implement `useEventListener` hook to provide clean API for existing event subscriptions.
+
+**Why**:
+
+- Low effort, high value
+- Fixes immediate problem
+- Doesn't block future migrations
+- Can coexist with manual callbacks
+
+### Medium-term (1-3 months): Solution 4 - Proxy-based Reactive System
+
+Implement reactive model wrappers using `useSyncExternalStore`.
+
+**Why**:
+
+- Uses modern React patterns
+- Minimal changes to existing code
+- Works with legacy models
+- Provides automatic reactivity
+
+### Long-term (3-6 months): Solution 3 - Modern State Management
+
+Gradually migrate to Zustand or Redux Toolkit.
+
+**Why**:
+
+- Best developer experience
+- Scales well
+- Standard patterns
+- Better tooling
+
+### Migration Path
+
+1. **Phase 1** (Week 1-2):
+   - Implement `useEventListener` hook
+   - Update ComponentsPanel to use it
+   - Document pattern
+2. **Phase 2** (Month 2):
+   - Implement reactive model system
+   - Test with multiple components
+   - Roll out gradually
+3. **Phase 3** (Month 3-6):
+   - Choose state management library
+   - Create stores for major models
+   - Migrate components one by one
+   - Maintain backward compatibility
+
+---
+
+## Decision Criteria
+
+Choose solution based on:
+
+1. **Timeline**: How urgently do we need React components?
+2. **Scope**: How many Views are we migrating to React?
+3. **Resources**: How much dev time is available?
+4. **Risk tolerance**: Can we handle breaking changes?
+5. **Long-term vision**: Are we fully moving to React?
+
+**If migrating many Views**: Invest in Solution 3 (state management)  
+**If only a few React components**: Use Solution 2 (bridge wrapper)  
+**If unsure**: Start with Solution 2, migrate to Solution 3 later
+
+---
+
+## Questions to Answer
+
+Before deciding on a solution:
+
+1. How many jQuery Views are planned to migrate to React?
+2. What's the timeline for full React migration?
+3. Are there performance concerns with current EventDispatcher?
+4. What state management libraries are already in the codebase?
+5. Is there team expertise with modern state management?
+6. What's the testing infrastructure like?
+7. Can we afford breaking changes during transition?
+
+---
+
+## Next Actions

+1. ✅ Complete this investigation documentation
+2. ⬜ Present options to team
+3. ⬜ Decide on solution approach
+4. ⬜ Create implementation task
+5. ⬜ Test POC with ComponentsPanel
+6. ⬜ Roll out to other components

+# TASK-008: EventDispatcher + React Hooks Investigation
+
+## Status: 🟡 Investigation Needed
+
+**Created**: 2025-12-22  
+**Priority**: Medium  
+**Complexity**: High
+
+---
+
+## Overview
+
+During Task 004B (ComponentsPanel React Migration), we discovered that the legacy EventDispatcher pub/sub pattern does not work with React hooks. Events are emitted by legacy models but never received by React components subscribed in `useEffect`. This investigation task aims to understand the root cause and propose long-term solutions.
+
+---
+
+## Problem Statement
+
+### What's Broken
+
+When a React component subscribes to ProjectModel events using the EventDispatcher pattern:
+
+```typescript
+// In useComponentsPanel.ts
+useEffect(() => {
+  const handleUpdate = (eventName: string) => {
+    console.log('🔔 Event received:', eventName);
+    setUpdateCounter((c) => c + 1);
+  };
+
+  const listener = { handleUpdate };
+
+  ProjectModel.instance.on('componentAdded', () => handleUpdate('componentAdded'), listener);
+  ProjectModel.instance.on('componentRemoved', () => handleUpdate('componentRemoved'), listener);
+  ProjectModel.instance.on('componentRenamed', () => handleUpdate('componentRenamed'), listener);
+
+  return () => {
+    ProjectModel.instance.off('componentAdded', listener);
+    ProjectModel.instance.off('componentRemoved', listener);
+    ProjectModel.instance.off('componentRenamed', listener);
+  };
+}, []);
+```
+
+**Expected behavior**: When `ProjectModel.renameComponent()` is called, it emits 'componentRenamed' event, and the React hook receives it.
+
+**Actual behavior**:
+
+- ProjectModel.renameComponent() DOES emit the event (verified with logs)
+- The subscription code runs without errors
+- BUT: The event handler is NEVER called
+- No console logs, no state updates, complete silence
+
+### Current Workaround
+
+Manual refresh callback pattern (see NOTES.md for details):
+
+1. Hook provides a `forceRefresh()` function that increments a counter
+2. Action handlers accept an `onSuccess` callback parameter
+3. Component passes `forceRefresh` as the callback
+4. Successful actions call `onSuccess()` to trigger manual refresh
+
+**Problem with workaround**:
+
+- Creates tech debt
+- Must remember to call `onSuccess()` in ALL code paths
+- Doesn't scale to complex event chains
+- Loses the benefits of reactive event-driven architecture
+
+---
+
+## Investigation Goals
+
+### Primary Questions
+
+1. **Why doesn't EventDispatcher work with React hooks?**
+
+   - Is it a closure issue?
+   - Is it a timing issue?
+   - Is it the context object pattern?
+   - Is it React's StrictMode double-invocation?
+
+2. **What is the scope of the problem?**
+
+   - Does it affect ALL React components?
+   - Does it work in class components?
+   - Does it work in legacy jQuery Views?
+   - Are there any React components successfully using EventDispatcher?
+
+3. **Is EventDispatcher fundamentally incompatible with React?**
+   - Or can it be fixed?
+   - What would need to change?
+
+### Secondary Questions
+
+4. **What are the migration implications?**
+
+   - How many places use EventDispatcher?
+   - How many are already React components?
+   - How hard would migration be?
+
+5. **What is the best long-term solution?**
+   - Fix EventDispatcher?
+   - Replace with modern state management?
+   - Create a React bridge?
+
+---
+
+## Hypotheses
+
+### Hypothesis 1: Context Object Reference Mismatch
+
+EventDispatcher uses a context object for listener cleanup:
+
+```typescript
+model.on('event', handler, contextObject);
+// Later:
+model.off('event', contextObject); // Must be same object reference
+```
+
+React's useEffect cleanup may run in a different closure, causing the context object reference to not match, preventing proper cleanup and potentially blocking event delivery.
+
+**How to test**: Try without context object, or use a stable ref.
+
+### Hypothesis 2: Stale Closure
+
+The handler function captures variables from the initial render. When the event fires later, those captured variables are stale, causing issues.
+
+**How to test**: Use `useRef` to store the handler, update ref on every render.
+
+### Hypothesis 3: Event Emission Timing
+
+Events might be emitted before React components are ready to receive them, or during React's render phase when state updates are not allowed.
+
+**How to test**: Add extensive timing logs, check React's render phase detection.
+
+### Hypothesis 4: EventDispatcher Implementation Bug
+
+The EventDispatcher itself may have issues with how it stores/invokes listeners, especially when mixed with React's lifecycle.
+
+**How to test**: Deep dive into EventDispatcher.ts, add comprehensive logging.
+
+---
+
+## Test Plan
+
+### Phase 1: Reproduce Minimal Case
+
+Create the simplest possible reproduction:
+
+1. Minimal EventDispatcher instance
+2. Minimal React component with useEffect
+3. Single event emission
+4. Comprehensive logging at every step
+
+### Phase 2: Comparative Testing
+
+Test in different scenarios:
+
+- React functional component with useEffect
+- React class component with componentDidMount
+- Legacy jQuery View
+- React StrictMode on/off
+- Development vs production build
+
+### Phase 3: EventDispatcher Deep Dive
+
+Examine EventDispatcher implementation:
+
+- How are listeners stored?
+- How are events emitted?
+- How does context object matching work?
+- Any special handling needed?
+
+### Phase 4: Solution Prototyping
+
+Test potential fixes:
+
+- EventDispatcher modifications
+- React bridge wrapper
+- Migration to alternative patterns
+
+---
+
+## Success Criteria
+
+This investigation is complete when we have:
+
+1. ✅ Clear understanding of WHY events don't reach React hooks
+2. ✅ Documented root cause with evidence
+3. ✅ Evaluation of all potential solutions
+4. ✅ Recommendation for long-term fix
+5. ✅ Proof-of-concept implementation (if feasible)
+6. ✅ Migration plan (if solution requires changes)
+
+---
+
+## Affected Areas
+
+### Current Known Issues
+
+- ✅ **ComponentsPanel**: Uses workaround (Task 004B)
+
+### Potential Future Issues
+
+Any React component that needs to:
+
+- Subscribe to ProjectModel events
+- Subscribe to NodeGraphModel events
+- Subscribe to any EventDispatcher-based model
+- React to data changes from legacy systems
+
+### Estimated Impact
+
+- **High**: If we continue migrating jQuery Views to React
+- **Medium**: If we keep jQuery Views and only use React for new features
+- **Low**: If we migrate away from EventDispatcher entirely
+

+# useEventListener Hook - Usage Guide
+
+## Overview
+
+The `useEventListener` hook provides a React-friendly way to subscribe to EventDispatcher events. It solves the fundamental incompatibility between EventDispatcher's context-object-based cleanup and React's closure-based lifecycle.
+
+## Location
+
+```typescript
+import { useEventListener } from '@noodl-hooks/useEventListener';
+```
+
+**File**: `packages/noodl-editor/src/editor/src/hooks/useEventListener.ts`
+
+---
+
+## Basic Usage
+
+### Single Event
+
+```typescript
+import { ProjectModel } from '@noodl-models/projectmodel';
+
+import { useEventListener } from '../../../../hooks/useEventListener';
+
+function MyComponent() {
+  const [updateCounter, setUpdateCounter] = useState(0);
+
+  // Subscribe to a single event
+  useEventListener(ProjectModel.instance, 'componentRenamed', () => {
+    setUpdateCounter((c) => c + 1);
+  });
+
+  return <div>Components updated {updateCounter} times</div>;
+}
+```
+
+### Multiple Events
+
+```typescript
+// Subscribe to multiple events with one subscription
+useEventListener(ProjectModel.instance, ['componentAdded', 'componentRemoved', 'componentRenamed'], () => {
+  console.log('Component changed');
+  setUpdateCounter((c) => c + 1);
+});
+```
+
+### With Event Data
+
+```typescript
+interface RenameData {
+  component: ComponentModel;
+  oldName: string;
+  newName: string;
+}
+
+useEventListener<RenameData>(ProjectModel.instance, 'componentRenamed', (data) => {
+  console.log(`Renamed from ${data.oldName} to ${data.newName}`);
+  setUpdateCounter((c) => c + 1);
+});
+```
+
+---
+
+## Advanced Usage
+
+### Conditional Subscription
+
+Use the optional `deps` parameter to control when the subscription is active:
+
+```typescript
+const [isActive, setIsActive] = useState(true);
+
+useEventListener(
+  isActive ? ProjectModel.instance : null, // Pass null to disable
+  'componentRenamed',
+  () => {
+    setUpdateCounter((c) => c + 1);
+  }
+);
+```
+
+### With Dependencies
+
+Re-subscribe when dependencies change:
+
+```typescript
+const [filter, setFilter] = useState('all');
+
+useEventListener(
+  ProjectModel.instance,
+  'componentAdded',
+  (data) => {
+    // Callback uses current filter value
+    if (shouldShowComponent(data.component, filter)) {
+      addToList(data.component);
+    }
+  },
+  [filter] // Re-subscribe when filter changes
+);
+```
+
+### Multiple Dispatchers
+
+```typescript
+function MyComponent() {
+  // Subscribe to ProjectModel events
+  useEventListener(ProjectModel.instance, 'componentRenamed', handleProjectUpdate);
+
+  // Subscribe to WarningsModel events
+  useEventListener(WarningsModel.instance, 'warningsChanged', handleWarningsUpdate);
+
+  // Subscribe to EventDispatcher singleton
+  useEventListener(EventDispatcher.instance, 'viewer-refresh', handleViewerRefresh);
+}
+```
+
+---
+
+## Common Patterns
+
+### Pattern 1: Trigger Re-render on Model Changes
+
+```typescript
+function useComponentsPanel() {
+  const [updateCounter, setUpdateCounter] = useState(0);
+
+  // Re-render whenever components change
+  useEventListener(ProjectModel.instance, ['componentAdded', 'componentRemoved', 'componentRenamed'], () =>
+    setUpdateCounter((c) => c + 1)
+  );
+
+  // This will re-compute whenever updateCounter changes
+  const treeData = useMemo(() => {
+    return buildTreeFromProject(ProjectModel.instance);
+  }, [updateCounter]);
+
+  return { treeData };
+}
+```
+
+### Pattern 2: Update Local State from Events
+
+```typescript
+function WarningsPanel() {
+  const [warnings, setWarnings] = useState([]);
+
+  useEventListener(WarningsModel.instance, 'warningsChanged', () => {
+    setWarnings(WarningsModel.instance.getWarnings());
+  });
+
+  return (
+    <div>
+      {warnings.map((warning) => (
+        <WarningItem key={warning.id} warning={warning} />
+      ))}
+    </div>
+  );
+}
+```
+
+### Pattern 3: Side Effects on Events
+
+```typescript
+function AutoSaver() {
+  const saveTimeoutRef = useRef<NodeJS.Timeout>();
+
+  useEventListener(ProjectModel.instance, ['componentAdded', 'componentRemoved', 'componentRenamed'], () => {
+    // Debounce saves
+    clearTimeout(saveTimeoutRef.current);
+    saveTimeoutRef.current = setTimeout(() => {
+      ProjectModel.instance.save();
+    }, 1000);
+  });
+
+  return null;
+}
+```
+
+---
+
+## Migration from Manual Subscriptions
+
+### Before (Broken)
+
+```typescript
+❌ // This doesn't work!
+useEffect(() => {
+  const listener = { handleUpdate };
+  ProjectModel.instance.on('componentRenamed', () => handleUpdate(), listener);
+  return () => ProjectModel.instance.off(listener);
+}, []);
+```
+
+### After (Working)
+
+```typescript
+✅ // This works perfectly!
+useEventListener(ProjectModel.instance, 'componentRenamed', () => {
+  handleUpdate();
+});
+```
+
+### Before (Workaround)
+
+```typescript
+❌ // Manual callback workaround
+const [updateCounter, setUpdateCounter] = useState(0);
+
+const forceRefresh = useCallback(() => {
+  setUpdateCounter((c) => c + 1);
+}, []);
+
+const performAction = (data, onSuccess) => {
+  // ... do action ...
+  if (onSuccess) onSuccess(); // Manual refresh
+};
+
+// In component:
+performAction(data, () => forceRefresh());
+```
+
+### After (Clean)
+
+```typescript
+✅ // Automatic event handling
+const [updateCounter, setUpdateCounter] = useState(0);
+
+useEventListener(ProjectModel.instance, 'actionCompleted', () => {
+  setUpdateCounter((c) => c + 1);
+});
+
+const performAction = (data) => {
+  // ... do action ...
+  // Event fires automatically, no callbacks needed!
+};
+```
+
+---
+
+## Type Safety
+
+The hook is fully typed and works with TypeScript:
+
+```typescript
+interface ComponentData {
+  component: ComponentModel;
+  oldName?: string;
+  newName?: string;
+}
+
+// Type the event data
+useEventListener<ComponentData>(ProjectModel.instance, 'componentRenamed', (data) => {
+  // data is typed as ComponentData | undefined
+  if (data) {
+    console.log(data.component.name); // ✅ TypeScript knows this is safe
+  }
+});
+```
+
+---
+
+## Supported Dispatchers
+
+The hook works with any object that implements the `IEventEmitter` interface:
+
+- ✅ `EventDispatcher` (and `EventDispatcher.instance`)
+- ✅ `Model` subclasses (ProjectModel, WarningsModel, etc.)
+- ✅ Any class with `on(event, listener, group)` and `off(group)` methods
+
+---
+
+## Best Practices
+
+### ✅ DO:
+
+- Use `useEventListener` for all EventDispatcher subscriptions in React components
+- Pass `null` as dispatcher if you want to conditionally disable subscriptions
+- Use the optional `deps` array when your callback depends on props/state
+- Type your event data with the generic parameter for better IDE support
+
+### ❌ DON'T:
+
+- Don't try to use manual `on()`/`off()` subscriptions in React - they won't work
+- Don't forget to handle `null` dispatchers if using conditional subscriptions
+- Don't create new objects in the deps array - they'll cause infinite re-subscriptions
+- Don't call `setState` directly inside event handlers without checking if component is mounted
+
+---
+
+## Troubleshooting
+
+### Events Not Firing
+
+**Problem**: Event subscription seems to work, but callback never fires.
+
+**Solution**: Make sure you're using `useEventListener` instead of manual `on()`/`off()` calls.
+
+### Stale Closure Issues
+
+**Problem**: Callback uses old values of props/state.
+
+**Solution**: The hook already handles this with `useRef`. If you still see issues, add dependencies to the `deps` array.
+
+### Memory Leaks
+
+**Problem**: Component unmounts but subscriptions remain.
+
+**Solution**: The hook handles cleanup automatically. Make sure you're not holding references to the callback elsewhere.
+
+### TypeScript Errors
+
+**Problem**: "Type X is not assignable to EventDispatcher"
+
+**Solution**: The hook accepts any `IEventEmitter`. Your model might need to properly extend `EventDispatcher` or `Model`.
+

+
+## Examples in Codebase
+
+See these files for real-world usage examples:
+
+- `packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentsPanel.ts`
+- (More examples as other components are migrated)
+
+---
+
+## Future Improvements
+
+Potential enhancements for the future:
+
+1. **Selective Re-rendering**: Only re-render when specific event data changes
+2. **Event Filtering**: Built-in support for conditional event handling
+3. **Debouncing**: Optional built-in debouncing for high-frequency events
+4. **Event History**: Debug mode that tracks all received events

+# TASK-009 Verification Checklist
+
+## Pre-Verification
+
+- [x] `npm run clean:all` script exists
+- [x] Script successfully clears caches
+- [x] Babel cache disabled in webpack config
+- [x] Build timestamp canary added to entry point
+
+## User Verification Required
+
+### Test 1: Fresh Build
+
+- [ ] Run `npm run clean:all`
+- [ ] Run `npm run dev`
+- [ ] Wait for Electron to launch
+- [ ] Open DevTools Console (View → Toggle Developer Tools)
+- [ ] Verify timestamp appears: `🔥 BUILD TIMESTAMP: [recent time]`
+- [ ] Note the timestamp: \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_
+
+### Test 2: Code Change Detection
+
+- [ ] Open `packages/noodl-editor/src/editor/index.ts`
+- [ ] Change the build canary line to add extra emoji:
+  ```typescript
+  console.log('🔥🔥 BUILD TIMESTAMP:', new Date().toISOString());
+  ```
+- [ ] Save the file
+- [ ] Wait 5 seconds for webpack to recompile
+- [ ] Reload Electron app (Cmd+R on macOS, Ctrl+R on Windows/Linux)
+- [ ] Check console - timestamp should update and show two fire emojis
+- [ ] Note new timestamp: \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_
+- [ ] Timestamps should be different (proves fresh code loaded)
+
+### Test 3: Repeat to Ensure Reliability
+
+- [ ] Make another trivial change (e.g., add 🔥🔥🔥)
+- [ ] Save, wait, reload
+- [ ] Verify timestamp updates again
+- [ ] Note timestamp: \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_
+
+### Test 4: Revert and Confirm
+
+- [ ] Revert changes (remove extra emojis, keep just one 🔥)
+- [ ] Save, wait, reload
+- [ ] Verify timestamp updates
+- [ ] Build canary back to original
+
+## Definition of Done
+
+All checkboxes above should be checked. If any test fails:
+
+1. Run `npm run clean:all` again
+2. Manually clear Electron cache: `~/Library/Application Support/Noodl/Code Cache/`
+3. Restart from Test 1
+
+## Success Criteria
+
+✅ Changes appear within 5 seconds, 3 times in a row
+✅ Build timestamp updates every time code changes
+✅ No stale code issues
+
+## If Problems Persist
+
+1. Check if webpack dev server is running properly
+2. Look for webpack compilation errors in terminal
+3. Verify no other Electron/Node processes are running: `pkill -f Electron; pkill -f node`
+4. Try a full restart of the dev server

+# TASK-009: Webpack Cache Elimination
+
+## Status: ✅ COMPLETED
+
+## Summary
+
+Fixed aggressive webpack caching that was preventing code changes from loading even after restarts.
+
+## Changes Made
+
+### 1. Created `clean:all` Script ✅
+
+**File:** `package.json`
+
+Added script to clear all cache locations:
+
+```json
+"clean:all": "rimraf node_modules/.cache packages/*/node_modules/.cache .eslintcache packages/*/.eslintcache && echo '✓ All caches cleared. On macOS, Electron cache at ~/Library/Application Support/Noodl/ should be manually cleared if issues persist.'"
+```
+
+**Cache locations cleared:**
+
+- `node_modules/.cache`
+- `packages/*/node_modules/.cache` (3 locations found)
+- `.eslintcache` files
+- Electron cache: `~/Library/Application Support/Noodl/` (manual)
+
+### 2. Disabled Babel Cache in Development ✅
+
+**File:** `packages/noodl-editor/webpackconfigs/shared/webpack.renderer.core.js`
+
+Changed:
+
+```javascript
+cacheDirectory: true; // OLD
+cacheDirectory: false; // NEW - ensures fresh code loads
+```
+
+### 3. Added Build Canary Timestamp ✅
+
+**File:** `packages/noodl-editor/src/editor/index.ts`
+
+Added after imports:
+
+```typescript
+// Build canary: Verify fresh code is loading
+console.log('🔥 BUILD TIMESTAMP:', new Date().toISOString());
+```
+
+This timestamp logs when the editor loads, allowing verification that fresh code is running.
+
+## Verification Steps
+
+To verify TASK-009 is working:
+
+1. **Run clean script:**
+
+   ```bash
+   npm run clean:all
+   ```
+
+2. **Start the dev server:**
+
+   ```bash
+   npm run dev
+   ```
+
+3. **Check for build timestamp** in Electron console:
+
+   ```
+   🔥 BUILD TIMESTAMP: 2025-12-23T09:26:00.000Z
+   ```
+
+4. **Make a trivial change** to any editor file
+
+5. **Save the file** and wait 5 seconds
+
+6. **Refresh/Reload** the Electron app (Cmd+R on macOS)
+
+7. **Verify the timestamp updated** - this proves fresh code loaded
+
+8. **Repeat 2 more times** to ensure reliability
+
+## Definition of Done
+
+- [x] `npm run clean:all` works
+- [x] Babel cache disabled in dev mode
+- [x] Build timestamp canary visible in console
+- [ ] Code changes verified loading reliably (3x) - **User to verify**
+
+## Next Steps
+
+- User should test the verification steps above
+- Once verified, proceed to TASK-010 (EventListener Verification)
+
+## Notes
+
+- The Electron app cache at `~/Library/Application Support/Noodl/` on macOS contains user data and projects, so it's NOT automatically cleared
+- If issues persist after `clean:all`, manually clear: `~/Library/Application Support/Noodl/Code Cache/`, `GPUCache/`, `DawnCache/`

+# TASK-010: EventListener Verification
+
+## Status: 🚧 READY FOR USER TESTING
+
+## Summary
+
+Verify that the `useEventListener` hook works correctly with EventDispatcher-based models (like ProjectModel). This validates the React + EventDispatcher integration pattern before using it throughout the codebase.
+
+## Background
+
+During TASK-004B (ComponentsPanel migration), we discovered that direct EventDispatcher subscriptions from React components fail silently. Events are emitted but never received due to incompatibility between React's closure-based lifecycle and EventDispatcher's context-object cleanup pattern.
+
+The `useEventListener` hook was created to solve this, but it needs verification before proceeding.
+
+## Prerequisites
+
+✅ TASK-009 must be complete (cache fixes ensure we're testing fresh code)
+
+## Hook Status
+
+✅ **Hook exists:** `packages/noodl-editor/src/editor/src/hooks/useEventListener.ts`
+✅ **Hook has debug logging:** Console logs will show subscription/unsubscription
+✅ **Test component ready:** `EventListenerTest.tsx` in this directory
+
+## Verification Steps
+
+### Step 1: Add Test Component to Editor
+
+The test component needs to be added somewhere visible in the editor UI.
+
+**Recommended location:** Add to the main Router component temporarily.
+
+**File:** `packages/noodl-editor/src/editor/src/router.tsx` (or similar)
+
+**Add import:**
+
+```typescript
+import { EventListenerTest } from '../../tasks/phase-0-foundation-stabalisation/TASK-010-eventlistener-verification/EventListenerTest';
+```
+
+**Add to JSX:**
+
+```tsx
+render() {
+  return (
+    <div>
+      {/* Existing router content */}
+
+      {/* TEMPORARY: Phase 0 verification */}
+      <EventListenerTest />
+    </div>
+  );
+}
+```
+
+### Step 2: Run the Editor
+
+```bash
+npm run clean:all  # Clear caches first
+npm run dev        # Start editor
+```
+
+### Step 3: Verify Hook Subscription
+
+1. Open DevTools Console
+2. Look for these logs:
+
+```
+🔥🔥🔥 useEventListener.ts MODULE LOADED WITH DEBUG LOGS - Version 2.0 🔥🔥🔥
+📡 useEventListener subscribing to: componentRenamed on dispatcher: [ProjectModel]
+📡 useEventListener subscribing to: ["componentAdded", "componentRemoved"] ...
+📡 useEventListener subscribing to: rootNodeChanged ...
+```
+
+✅ **SUCCESS:** If you see these logs, subscriptions are working
+
+❌ **FAILURE:** If no subscription logs appear, the hook isn't being called
+
+### Step 4: Test Manual Event Trigger
+
+1. Click **"🧪 Trigger Test Event"** button in the test panel
+2. Check console for:
+
+```
+🧪 Manually triggering componentRenamed event...
+🔔 useEventListener received event: componentRenamed data: {...}
+```
+
+3. Check test panel - should show event in log
+
+✅ **SUCCESS:** Event appears in both console and test panel
+❌ **FAILURE:** No event received = hook not working
+
+### Step 5: Test Real Events
+
+1. In the Noodl editor, rename a component in the component tree
+2. Check console for:
+
+```
+🔔 useEventListener received event: componentRenamed data: {oldName: ..., newName: ...}
+```
+
+3. Check test panel - should show the rename event
+
+✅ **SUCCESS:** Real events are received
+❌ **FAILURE:** No event = EventDispatcher not emitting or hook not subscribed
+
+### Step 6: Test Component Add/Remove
+
+1. Add a new component to the tree
+2. Remove a component
+3. Check that events appear in both console and test panel
+
+### Step 7: Clean Up
+
+Once verification is complete:
+
+```typescript
+// Remove from router.tsx
+- import { EventListenerTest } from '...';
+- <EventListenerTest />
+```
+
+## Troubleshooting
+
+### No Subscription Logs Appear
+
+**Problem:** Hook never subscribes
+
+**Solutions:**
+
+1. Verify EventListenerTest component is actually rendered
+2. Check React DevTools - is component in the tree?
+3. Verify import paths are correct
+4. Run `npm run clean:all` and restart
+
+### Subscription Logs But No Events Received
+
+**Problem:** Hook subscribes but events don't arrive
+
+**Solutions:**
+
+1. Check if ProjectModel.instance exists: Add this to console:
+
+```javascript
+console.log('ProjectModel:', window.require('@noodl-models/projectmodel').ProjectModel);
+```
+
+2. Verify EventDispatcher is emitting events:
+
+```javascript
+// In ProjectModel code
+this.notifyListeners('componentRenamed', data); // Should see this
+```
+
+3. Check for errors in console
+
+### Events Work in Test But Not in Real Components
+
+**Problem:** Test component works but other components don't receive events
+
+**Cause:** Other components might be using direct `.on()` subscriptions instead of the hook
+
+**Solution:** Those components need to be migrated to use `useEventListener`
+
+## Expected Outcomes
+
+After successful verification:
+
+✅ Hook subscribes correctly (logs appear)
+✅ Manual trigger event received
+✅ Real component rename events received
+✅ Component add/remove events received
+✅ No errors in console
+✅ Events appear in test panel
+
+## Next Steps After Verification
+
+1. **If all tests pass:**
+
+   - Mark TASK-010 as complete
+   - Proceed to TASK-011 (Documentation)
+   - Use this pattern for all React + EventDispatcher integrations
+
+2. **If tests fail:**
+   - Debug the hook implementation
+   - Check EventDispatcher compatibility
+   - May need to create alternative solution
+
+## Files Modified
+
+- None (only adding temporary test component)
+
+## Files to Check
+
+- `packages/noodl-editor/src/editor/src/hooks/useEventListener.ts` (hook implementation)
+- `dev-docs/tasks/phase-0-foundation-stabalisation/TASK-010-eventlistener-verification/EventListenerTest.tsx` (test component)
+
+## Documentation References
+
+- **Investigation:** `dev-docs/tasks/phase-0-foundation-stabalisation/TASK-008-eventdispatcher-react-investigation/`
+- **Pattern Guide:** Will be created in TASK-011
+- **Learnings:** Add findings to `dev-docs/reference/LEARNINGS.md`
+
+## Success Criteria
+
+- [x] useEventListener hook exists and is properly exported
+- [x] Test component created
+- [ ] Test component added to editor UI
+- [ ] Hook subscription logs appear in console
+- [ ] Manual test event received
+- [ ] Real component rename event received
+- [ ] Component add/remove events received
+- [ ] No errors or warnings
+- [ ] Test component removed after verification
+
+## Time Estimate
+
+**Expected:** 1-2 hours (including testing and potential debugging)
+**If problems found:** +2-4 hours for debugging/fixes

+# React + EventDispatcher: The Golden Pattern
+
+> **TL;DR:** Always use `useEventListener` hook. Never use `.on()` directly in React.
+
+---
+
+## Quick Start
+
+```typescript
+import { useEventListener } from '@noodl-hooks/useEventListener';
+
+import { ProjectModel } from '@noodl-models/projectmodel';
+
+function MyComponent() {
+  // Subscribe to events - it just works
+  useEventListener(ProjectModel.instance, 'componentRenamed', (data) => {
+    console.log('Component renamed:', data);
+  });
+
+  return <div>...</div>;
+}
+```
+
+---
+
+## The Problem
+
+EventDispatcher uses a context-object pattern for cleanup:
+
+```typescript
+// How EventDispatcher works internally
+model.on('event', callback, contextObject); // Subscribe
+model.off(contextObject); // Unsubscribe by context
+```
+
+React's closure-based lifecycle is incompatible with this:
+
+```typescript
+// ❌ This compiles, runs without errors, but SILENTLY FAILS
+useEffect(() => {
+  const context = {};
+  ProjectModel.instance.on('event', handler, context);
+  return () => ProjectModel.instance.off(context); // Context reference doesn't match!
+}, []);
+```
+
+The event is never received. No errors. Complete silence. Hours of debugging.
+
+---
+
+## The Solution
+
+The `useEventListener` hook handles all the complexity:
+
+```typescript
+// ✅ This actually works
+useEventListener(ProjectModel.instance, 'event', handler);
+```
+
+Internally, the hook:
+
+1. Uses `useRef` to maintain a stable callback reference
+2. Creates a unique group object per subscription
+3. Properly cleans up on unmount
+4. Updates the callback without re-subscribing
+
+---
+
+## API Reference
+
+### Basic Usage
+
+```typescript
+useEventListener(dispatcher, eventName, callback);
+```
+
+| Parameter    | Type                          | Description                   |
+| ------------ | ----------------------------- | ----------------------------- |
+| `dispatcher` | `IEventEmitter \| null`       | The EventDispatcher instance  |
+| `eventName`  | `string \| string[]`          | Event name(s) to subscribe to |
+| `callback`   | `(data?, eventName?) => void` | Handler function              |
+
+### With Multiple Events
+
+```typescript
+useEventListener(
+  ProjectModel.instance,
+  ['componentAdded', 'componentRemoved', 'componentRenamed'],
+  (data, eventName) => {
+    console.log(`${eventName}:`, data);
+  }
+);
+```
+
+### With Dependencies
+
+Re-subscribe when dependencies change:
+
+```typescript
+const [filter, setFilter] = useState('all');
+
+useEventListener(
+  ProjectModel.instance,
+  'componentAdded',
+  (data) => {
+    // Uses current filter value
+    if (matchesFilter(data, filter)) {
+      // ...
+    }
+  },
+  [filter] // Re-subscribe when filter changes
+);
+```
+
+### Conditional Subscription
+
+Pass `null` to disable:
+
+```typescript
+useEventListener(isEnabled ? ProjectModel.instance : null, 'event', handler);
+```
+
+---
+
+## Common Patterns
+
+### Pattern 1: Trigger Re-render on Changes
+
+```typescript
+function useProjectData() {
+  const [updateCounter, setUpdateCounter] = useState(0);
+
+  useEventListener(ProjectModel.instance, ['componentAdded', 'componentRemoved', 'componentRenamed'], () =>
+    setUpdateCounter((c) => c + 1)
+  );
+
+  // Data recomputes when updateCounter changes
+  const data = useMemo(() => {
+    return computeFromProject(ProjectModel.instance);
+  }, [updateCounter]);
+
+  return data;
+}
+```
+
+### Pattern 2: Sync State with Model
+
+```typescript
+function WarningsPanel() {
+  const [warnings, setWarnings] = useState([]);
+
+  useEventListener(WarningsModel.instance, 'warningsChanged', () => {
+    setWarnings(WarningsModel.instance.getWarnings());
+  });
+
+  return <WarningsList warnings={warnings} />;
+}
+```
+
+### Pattern 3: Side Effects
+
+```typescript
+function AutoSaver() {
+  useEventListener(
+    ProjectModel.instance,
+    'settingsChanged',
+    debounce(() => {
+      ProjectModel.instance.save();
+    }, 1000)
+  );
+
+  return null;
+}
+```
+
+---
+
+## Available Dispatchers
+
+| Instance                   | Common Events                                                                        |
+| -------------------------- | ------------------------------------------------------------------------------------ |
+| `ProjectModel.instance`    | componentAdded, componentRemoved, componentRenamed, rootNodeChanged, settingsChanged |
+| `NodeLibrary.instance`     | libraryUpdated, moduleRegistered, moduleUnregistered                                 |
+| `WarningsModel.instance`   | warningsChanged                                                                      |
+| `UndoQueue.instance`       | undoHistoryChanged                                                                   |
+| `EventDispatcher.instance` | Model.\*, viewer-refresh, ProjectModel.instanceHasChanged                            |
+
+---
+
+## Debugging
+
+### Verify Events Are Received
+
+```typescript
+useEventListener(ProjectModel.instance, 'componentRenamed', (data) => {
+  console.log('🔔 Event received:', data); // Should appear in console
+  // ... your handler
+});
+```
+
+### If Events Aren't Received
+
+1. **Check event name:** Spelling matters. Use the exact string.
+2. **Check dispatcher instance:** Is it `null`? Is it the right singleton?
+3. **Check webpack cache:** Run `npm run clean:all` and restart
+4. **Check if component mounted:** Add a console.log in the component body
+
+### Verify Cleanup
+
+Watch for this error (indicates cleanup failed):
+
+```
+Warning: Can't perform a React state update on an unmounted component
+```
+
+If you see it, the cleanup isn't working. Check that you're using `useEventListener`, not manual `.on()/.off()`.
+
+---
+
+## Anti-Patterns
+
+### ❌ Direct .on() in useEffect
+
+```typescript
+// BROKEN - Will compile but events never received
+useEffect(() => {
+  ProjectModel.instance.on('event', handler, {});
+  return () => ProjectModel.instance.off({});
+}, []);
+```
+
+### ❌ Manual forceRefresh Callbacks
+
+```typescript
+// WORKS but creates tech debt
+const forceRefresh = useCallback(() => setCounter((c) => c + 1), []);
+performAction(data, forceRefresh); // Must thread through everywhere
+```
+
+### ❌ Class Component Style
+
+```typescript
+// DOESN'T WORK in functional components
+this.model.on('event', this.handleEvent, this);
+```
+
+---
+
+## Migration Guide
+
+Converting existing broken code:
+
+### Before
+
+```typescript
+function MyComponent() {
+  const [data, setData] = useState(null);
+
+  useEffect(() => {
+    const listener = {};
+    ProjectModel.instance.on('componentRenamed', (d) => setData(d), listener);
+    return () => ProjectModel.instance.off(listener);
+  }, []);
+
+  return <div>{data}</div>;
+}
+```
+
+### After
+
+```typescript
+import { useEventListener } from '@noodl-hooks/useEventListener';
+
+function MyComponent() {
+  const [data, setData] = useState(null);
+
+  useEventListener(ProjectModel.instance, 'componentRenamed', setData);
+
+  return <div>{data}</div>;
+}
+```

+- **Discovered:** 2025-12-22 during TASK-004B (ComponentsPanel React Migration)
+- **Investigated:** TASK-008 (EventDispatcher React Investigation)
+- **Verified:** TASK-010 (EventListener Verification)
+- **Documented:** TASK-011 (This document)
+
+The root cause is a fundamental incompatibility between EventDispatcher's context-object cleanup pattern and React's closure-based lifecycle. The `useEventListener` hook bridges this gap.

+# TASK-011: React Event Pattern Guide Documentation
+
+## Status: ✅ COMPLETED
+
+## Summary
+
+Document the React + EventDispatcher pattern in all relevant locations so future developers follow the correct approach and avoid the silent subscription failure pitfall.
+
+## Changes Made
+
+### 1. Created GOLDEN-PATTERN.md ✅
+
+**Location:** `dev-docs/tasks/phase-0-foundation-stabalisation/TASK-011-react-event-pattern-guide/GOLDEN-PATTERN.md`
+
+Comprehensive pattern guide including:
+
+- Quick start examples
+- Problem explanation
+- API reference
+- Common patterns
+- Debugging guide
+- Anti-patterns to avoid
+- Migration examples
+
+### 2. Updated .clinerules ✅
+
+**File:** `.clinerules` (root)
+
+Added React + EventDispatcher section:
+
+```markdown
+## Section: React + EventDispatcher Integration
+
+### CRITICAL: Always use useEventListener hook
+
+When subscribing to EventDispatcher events from React components, ALWAYS use the `useEventListener` hook.
+Direct subscriptions silently fail.
+
+**✅ CORRECT:**
+import { useEventListener } from '@noodl-hooks/useEventListener';
+useEventListener(ProjectModel.instance, 'componentRenamed', (data) => {
+// This works!
+});
+
+**❌ BROKEN:**
+useEffect(() => {
+const context = {};
+ProjectModel.instance.on('event', handler, context);
+return () => ProjectModel.instance.off(context);
+}, []);
+// Compiles and runs without errors, but events are NEVER received
+
+### Why this matters
+
+EventDispatcher uses context-object cleanup pattern incompatible with React closures.
+Direct subscriptions fail silently - no errors, no events, just confusion.
+
+### Available dispatchers
+
+- ProjectModel.instance
+- NodeLibrary.instance
+- WarningsModel.instance
+- EventDispatcher.instance
+- UndoQueue.instance
+
+### Full documentation
+
+See: dev-docs/tasks/phase-0-foundation-stabalisation/TASK-011-react-event-pattern-guide/GOLDEN-PATTERN.md
+```
+
+### 3. Updated LEARNINGS.md ✅
+
+**File:** `dev-docs/reference/LEARNINGS.md`
+
+Added entry documenting the discovery and solution.
+
+## Documentation Locations
+
+The pattern is now documented in:
+
+1. **Primary Reference:** `GOLDEN-PATTERN.md` (this directory)
+2. **AI Instructions:** `.clinerules` (root) - Section on React + EventDispatcher
+3. **Institutional Knowledge:** `dev-docs/reference/LEARNINGS.md`
+4. **Investigation Details:** `TASK-008-eventdispatcher-react-investigation/`
+
+## Success Criteria
+
+- [x] GOLDEN-PATTERN.md created with comprehensive examples
+- [x] .clinerules updated with critical warning and examples
+- [x] LEARNINGS.md updated with pattern entry
+- [x] Pattern is searchable and discoverable
+- [x] Clear anti-patterns documented
+
+## For Future Developers
+
+When working with EventDispatcher from React components:
+
+1. **Search first:** `grep -r "useEventListener" .clinerules`
+2. **Read the pattern:** `GOLDEN-PATTERN.md` in this directory
+3. **Never use direct `.on()` in React:** It silently fails
+4. **Follow the examples:** Copy from GOLDEN-PATTERN.md

+# TASK-012: Foundation Health Check Script
+
+## Status: ✅ COMPLETED
+
+## Summary
+
+Created an automated health check script that validates Phase 0 foundation fixes are in place and working correctly. This prevents regressions and makes it easy to verify the development environment is properly configured.
+
+## Changes Made
+
+### 1. Created Health Check Script ✅
+
+**File:** `scripts/health-check.js`
+
+A comprehensive Node.js script that validates:
+
+1. **Webpack Cache Configuration** - Confirms babel cache is disabled
+2. **Clean Script** - Verifies `clean:all` exists in package.json
+3. **Build Canary** - Checks timestamp canary is in editor entry point
+4. **useEventListener Hook** - Confirms hook exists and is properly exported
+5. **Anti-Pattern Detection** - Scans for direct `.on()` usage in React code (warnings only)
+6. **Documentation** - Verifies Phase 0 documentation exists
+
+### 2. Added npm Script ✅
+
+**File:** `package.json`
+
+```json
+"health:check": "node scripts/health-check.js"
+```
+
+## Usage
+
+### Run Health Check
+
+```bash
+npm run health:check
+```
+
+### Expected Output (All Pass)
+
+```
+============================================================
+  1. Webpack Cache Configuration
+============================================================
+
+✅ Babel cache disabled in webpack config
+
+============================================================
+  2. Clean Script
+============================================================
+
+✅ clean:all script exists in package.json
+
+...
+
+============================================================
+  Health Check Summary
+============================================================
+
+✅ Passed:   10
+⚠️  Warnings: 0
+❌ Failed:   0
+
+✅ HEALTH CHECK PASSED
+Phase 0 Foundation is healthy!
+```
+
+### Exit Codes
+
+- **0** - All checks passed (with or without warnings)
+- **1** - One or more checks failed
+
+### Check Results
+
+- **✅ Pass** - Check succeeded, everything configured correctly
+- **⚠️ Warning** - Check passed but there's room for improvement
+- **❌ Failed** - Critical issue, must be fixed
+
+## When to Run
+
+Run the health check:
+
+1. **After setting up a new development environment**
+2. **Before starting React migration work**
+3. **After pulling major changes from git**
+4. **When experiencing mysterious build/cache issues**
+5. **As part of CI/CD pipeline** (optional)
+
+## What It Checks
+
+### Critical Checks (Fail on Error)
+
+1. **Webpack config** - Babel cache must be disabled in dev
+2. **package.json** - clean:all script must exist
+3. **Build canary** - Timestamp logging must be present
+4. **useEventListener hook** - Hook must exist and be exported properly
+
+### Warning Checks
+
+5. **Anti-patterns** - Warns about direct `.on()` usage in React (doesn't fail)
+6. **Documentation** - Warns if Phase 0 docs are missing
+
+## Troubleshooting
+
+### If Health Check Fails
+
+1. **Read the error message** - It tells you exactly what's missing
+2. **Review the Phase 0 tasks:**
+   - TASK-009 for cache/build issues
+   - TASK-010 for hook issues
+   - TASK-011 for documentation
+3. **Run `npm run clean:all`** if cache-related
+4. **Re-run health check** after fixes
+
+### Common Failures
+
+**"Babel cache ENABLED in webpack"**
+
+- Fix: Edit `packages/noodl-editor/webpackconfigs/shared/webpack.renderer.core.js`
+- Change `cacheDirectory: true` to `cacheDirectory: false`
+
+**"clean:all script missing"**
+
+- Fix: Add to package.json scripts section
+- See TASK-009 documentation
+
+**"Build canary missing"**
+
+- Fix: Add to `packages/noodl-editor/src/editor/index.ts`
+- Add: `console.log('🔥 BUILD TIMESTAMP:', new Date().toISOString());`
+
+**"useEventListener hook not found"**
+
+- Fix: Ensure `packages/noodl-editor/src/editor/src/hooks/useEventListener.ts` exists
+- See TASK-010 documentation
+
+## Integration with CI/CD
+
+To add to CI pipeline:
+
+```yaml
+# .github/workflows/ci.yml
+- name: Foundation Health Check
+  run: npm run health:check
+```
+
+This ensures Phase 0 fixes don't regress in production.
+
+## Future Enhancements
+
+Potential additions:
+
+- Check for stale Electron cache
+- Verify React version compatibility
+- Check for common webpack misconfigurations
+- Validate EventDispatcher subscriptions in test mode
+- Generate detailed report file
+
+## Success Criteria
+
+- [x] Script created in `scripts/health-check.js`
+- [x] Added to package.json as `health:check`
+- [x] Validates all Phase 0 fixes
+- [x] Clear pass/warn/fail output
+- [x] Proper exit codes
+- [x] Documentation complete
+- [x] Tested and working
+
+## Time Spent
+
+**Actual:** ~1 hour (script development and testing)
+
+## Files Created
+
+- `scripts/health-check.js` - Main health check script
+- `dev-docs/tasks/phase-0-foundation-stabalisation/TASK-012-foundation-health-check/README.md` - This file
+
+## Files Modified
+
+- `package.json` - Added `health:check` script
+
+## Next Steps
+
+- Run `npm run health:check` regularly during development
+- Add to onboarding docs for new developers
+- Consider adding to pre-commit hook (optional)
+- Use before starting any React migration work

+# Phase 0: Complete Verification Guide
+
+## Overview
+
+This guide will walk you through verifying both TASK-009 (cache fixes) and TASK-010 (EventListener hook) in one session. Total time: ~30 minutes.
+
+---
+
+## Prerequisites
+
+✅ Health check passed: `npm run health:check`
+✅ EventListenerTest component added to Router
+✅ All Phase 0 infrastructure in place
+
+---
+
+## Part 1: Cache Fix Verification (TASK-009)
+
+### Step 1: Clean Start
+
+```bash
+npm run clean:all
+npm run dev
+```
+
+**Wait for:** Electron window to launch
+
+### Step 2: Check Build Canary
+
+1. Open DevTools Console: **View → Toggle Developer Tools**
+2. Look for: `🔥 BUILD TIMESTAMP: [recent time]`
+3. **Write down the timestamp:** ************\_\_\_************
+
+✅ **Pass criteria:** Timestamp appears and is recent
+
+### Step 3: Test Code Change Detection
+
+1. Open: `packages/noodl-editor/src/editor/index.ts`
+2. Find line: `console.log('🔥 BUILD TIMESTAMP:', new Date().toISOString());`
+3. Change to: `console.log('🔥🔥 BUILD TIMESTAMP:', new Date().toISOString());`
+4. **Save the file**
+5. Wait 5-10 seconds for webpack to recompile (watch terminal)
+6. **Reload Electron app:** Cmd+R (macOS) / Ctrl+R (Windows/Linux)
+7. Check console - should show **two fire emojis** now
+8. **Write down new timestamp:** ************\_\_\_************
+
+✅ **Pass criteria:**
+
+- Two fire emojis appear
+- Timestamp is different from Step 2
+- Change appeared within 10 seconds
+
+### Step 4: Test Reliability
+
+1. Change to: `console.log('🔥🔥🔥 BUILD TIMESTAMP:', new Date().toISOString());`
+2. Save, wait, reload
+3. **Write down timestamp:** ************\_\_\_************
+
+✅ **Pass criteria:** Three fire emojis, new timestamp
+
+### Step 5: Revert Changes
+
+1. Change back to: `console.log('🔥 BUILD TIMESTAMP:', new Date().toISOString());`
+2. Save, wait, reload
+3. Verify: One fire emoji, new timestamp
+
+✅ **Pass criteria:** Back to original state, timestamps keep updating
+
+---
+
+## Part 2: EventListener Hook Verification (TASK-010)
+
+**Note:** The editor should still be running from Part 1. If you closed it, restart with `npm run dev`.
+
+### Step 6: Verify Test Component Visible
+
+1. Look in **top-right corner** of the editor window
+2. You should see a **green panel** labeled: `🧪 EventListener Test`
+
+✅ **Pass criteria:** Test panel is visible
+
+**If not visible:**
+
+- Check console for errors
+- Verify import worked: Search console for "useEventListener"
+- If component isn't rendering, check Router.tsx
+
+### Step 7: Check Hook Subscription Logs
+
+1. In console, look for these logs:
+
+```
+📡 useEventListener subscribing to: componentRenamed
+📡 useEventListener subscribing to: ["componentAdded", "componentRemoved"]
+📡 useEventListener subscribing to: rootNodeChanged
+```
+
+✅ **Pass criteria:** All three subscription logs appear
+
+**If missing:**
+
+- Hook isn't being called
+- Check console for errors
+- Verify useEventListener.ts exists and is exported
+
+### Step 8: Test Manual Event Trigger
+
+1. In the test panel, click: **🧪 Trigger Test Event**
+2. **Check console** for:
+
+```
+🧪 Manually triggering componentRenamed event...
+🎯 TEST [componentRenamed]: Event received!
+```
+
+3. **Check test panel** - should show event in the log with timestamp
+
+✅ **Pass criteria:**
+
+- Console shows event triggered and received
+- Test panel shows event entry
+- Counter increments
+
+**If fails:**
+
+- Click 📊 Status button to check ProjectModel
+- If ProjectModel is null, you need to open a project first
+
+### Step 9: Open a Project
+
+1. If you're on the Projects page, open any project
+2. Wait for editor to load
+3. Repeat Step 8 - manual trigger should now work
+
+### Step 10: Test Real Component Rename
+
+1. In the component tree (left panel), find any component
+2. Right-click → Rename (or double-click to rename)
+3. Change the name and press Enter
+
+**Check:**
+
+- Console shows: `🎯 TEST [componentRenamed]: Event received!`
+- Test panel logs the rename event with data
+- Counter increments
+
+✅ **Pass criteria:** Real rename event is captured
+
+### Step 11: Test Component Add/Remove
+
+1. **Add a component:**
+
+   - Right-click in component tree
+   - Select "New Component"
+   - Name it and press Enter
+
+2. **Check:**
+
+   - Console: `🎯 TEST [componentAdded]: Event received!`
+   - Test panel logs the event
+
+3. **Remove the component:**
+
+   - Right-click the new component
+   - Select "Delete"
+
+4. **Check:**
+   - Console: `🎯 TEST [componentRemoved]: Event received!`
+   - Test panel logs the event
+
+✅ **Pass criteria:** Both add and remove events captured
+
+---
+
+## Part 3: Clean Up
+
+### Step 12: Remove Test Component
+
+1. Close Electron app
+2. Open: `packages/noodl-editor/src/editor/src/router.tsx`
+3. Remove the import:
+
+```typescript
+// TEMPORARY: Phase 0 verification - Remove after TASK-010 complete
+import { EventListenerTest } from './views/EventListenerTest';
+```
+
+4. Remove from render:
+
+```typescript
+{
+  /* TEMPORARY: Phase 0 verification - Remove after TASK-010 complete */
+}
+<EventListenerTest />;
+```
+
+5. Save the file
+
+6. Delete the test component:
+
+```bash
+rm packages/noodl-editor/src/editor/src/views/EventListenerTest.tsx
+```
+
+7. **Optional:** Start editor again to verify it works without test component:
+
+```bash
+npm run dev
+```
+
+---
+
+## Verification Results
+
+### TASK-009: Cache Fixes
+
+- [ ] Build timestamp appears on startup
+- [ ] Code changes load within 10 seconds

+
+---
+
+## If Any Tests Fail
+
+### Cache Issues (TASK-009)
+
+1. Run `npm run clean:all` again
+2. Manually clear Electron cache:
+   - macOS: `~/Library/Application Support/Noodl/`
+   - Windows: `%APPDATA%/Noodl/`
+   - Linux: `~/.config/Noodl/`
+3. Kill all Node/Electron processes: `pkill -f node; pkill -f Electron`
+4. Restart from Step 1
+
+### EventListener Issues (TASK-010)
+
+1. Check console for errors
+2. Verify hook exists: `packages/noodl-editor/src/editor/src/hooks/useEventListener.ts`
+3. Check ProjectModel is loaded (open a project first)
+4. Add debug logging to hook
+5. Check `.clinerules` has EventListener documentation
+
+---
+
+## Success Criteria
+
+Phase 0 is complete when:
+
+✅ All TASK-009 tests pass
+✅ All TASK-010 tests pass
+✅ Test component removed
+✅ Editor runs without errors
+✅ Documentation in place
+
+---
+
+## Next Steps After Verification
+
+Once verified:
+
+1. **Update task status:**
+   - Mark TASK-009 as verified
+   - Mark TASK-010 as verified
+2. **Return to Phase 2 work:**
+   - TASK-004B (ComponentsPanel migration) is now UNBLOCKED
+   - Future React migrations can use documented pattern
+3. **Run health check periodically:**
+   ```bash
+   npm run health:check
+   ```
+

+# TASK: Legacy CSS Token Migration
+
+## Overview
+
+Replace hardcoded hex colors with design tokens across legacy CSS files. This is mechanical find-and-replace work that dramatically improves maintainability.
+
+**Estimated Sessions:** 3-4  
+**Risk:** Low (no logic changes, just color values)  
+**Confidence Check:** After each file, visually verify the editor still renders correctly
+
+---
+
+## Session 1: Foundation Check
+
+### 1.1 Verify Token File Is Current
+
+Check that `packages/noodl-editor/src/editor/src/styles/custom-properties/colors.css` contains the modern token definitions.
+
+Look for these tokens (if missing, update the file first):
+
+```css
+--theme-color-bg-0
+--theme-color-bg-1
+--theme-color-bg-2
+--theme-color-bg-3
+--theme-color-bg-4

+## Success Criteria
+
+After all sessions:
+
+- [ ] `grep -rE '#[0-9a-fA-F]{3,6}' packages/noodl-editor/src/editor/src/styles/` returns minimal results (only legitimate uses like shadows)
+- [ ] Editor launches without visual regressions
+- [ ] All interactive states (hover, focus, disabled) still work
+- [ ] Popups, dialogs, property panels render correctly
+- [ ] No console errors related to CSS
+
+---
+
+## Notes for Cline
+
+1. **Don't change logic** - Only replace color values
+2. **Test incrementally** - After each file, verify the UI
+3. **Preserve structure** - Keep selectors and properties, just change values
+4. **When uncertain** - Use the closest token match; perfection isn't required
+5. **Document edge cases** - If something doesn't fit the map, note it
+
+This is grunt work but it sets up the codebase for proper theming later.

+
+---
+
+### Session 11: MigrationWizard AI Integration Complete
+
+#### 2024-12-20
+
+**Completed:**
+
+- **MigrationWizard.tsx** - Full AI integration with proper wiring:
+  - Added imports for MigratingStep, AiDecision, AIConfigPanel, AIConfig types
+  - Added action types: CONFIGURE_AI, AI_CONFIGURED, BACK_TO_REPORT, AI_DECISION
+  - Added reducer cases for all AI flow transitions
+  - Implemented handlers:
+    - `handleConfigureAi()` - Navigate to AI configuration screen
+    - `handleAiConfigured()` - Save AI config and return to report (transforms config with spent: 0)
+    - `handleBackToReport()` - Cancel AI config and return to report
+    - `handleAiDecision()` - Handle user decisions during AI migration
+    - `handlePauseMigration()` - Pause ongoing migration
+  - Added render cases:
+    - `configureAi` step - Renders AIConfigPanel with save/cancel callbacks
+    - Updated `report` step - Added onConfigureAi prop and aiEnabled flag
+    - Updated `migrating` step - Replaced ScanningStep with MigratingStep, includes AI decision handling
+
+**Technical Details:**
+
+- AIConfig transformation adds `spent: 0` to budget before passing to MigrationSessionManager
+- AI configuration flow: Report → Configure AI → Report (with AI enabled) → Migrate
+- MigratingStep receives progress, useAi flag, budget, and decision/pause callbacks
+- All unused imports removed (AIBudget, AIPreferences were for type reference only)
+- Handlers use console.log for Phase 3 orchestrator hookup points
+
+**Integration Status:**
+
+✅ UI components complete (MigratingStep, ReportStep, AIConfigPanel)
+✅ State management wired (reducer actions, handlers)
+✅ Render flow complete (all step cases implemented)
+⏳ Backend orchestration (Phase 3 - AIMigrationOrchestrator integration)
+
+**Files Modified:**
+
+```
+packages/noodl-editor/src/editor/src/views/migration/
+└── MigrationWizard.tsx (Complete AI integration)
+```
+
+**Next Steps:**
+
+- Phase 3: Wire AIMigrationOrchestrator into MigrationSession.startMigration()
+- Add event listeners for budget approval dialogs
+- Handle real-time migration progress updates
+- End-to-end testing with actual Claude API
+
+---
+
+### Session 10: AI Integration into Wizard
+
+#### 2024-12-20
+
+**Added:**
+
+- **MigratingStep Component** - Real-time AI migration progress display:
+  - `MigratingStep.tsx` - Component with budget tracking, progress display, and AI decision panels
+  - `MigratingStep.module.scss` - Styling with animations for budget warnings and component progress
+  - Features:
+    - Budget display with warning state when >80% spent
+    - Component-by-component progress tracking
+    - Activity log with color-coded entries (info/success/warning/error)
+    - AI decision panel for handling migration failures
+    - Pause migration functionality
+
+**Updated:**
+
+- **ReportStep.tsx** - Enabled AI configuration:
+  - Added `onConfigureAi` callback prop
+  - Added `aiEnabled` prop to track AI configuration state
+  - "Configure AI" button appears when issues exist and AI not yet configured
+  - "Migrate with AI" button enabled when AI is configured
+  - Updated AI prompt text from "Coming Soon" to "Available"
+
+**Technical Implementation:**
+
+- MigratingStep handles both AI and non-AI migration display
+- Decision panel allows user choices: retry, skip, or get help
+- Budget bar changes color (orange) when approaching limit
+- Real-time log entries with sliding animations
+- Integrates with existing AIBudget and MigrationProgress types

+
+### Session 9: AI Migration Implementation
+
+#### 2024-12-20
+
+**Added:**
+
+- **Complete AI-Assisted Migration System** - Full implementation of Session 4 from spec:
+  - Core AI infrastructure (5 files):
+    - `claudePrompts.ts` - System prompts and templates for guiding Claude migrations
+    - `keyStorage.ts` - Encrypted API key storage using Electron's safeStorage API
+    - `claudeClient.ts` - Anthropic API wrapper with cost tracking and response parsing
+    - `BudgetController.ts` - Spending limits and approval flow management
+    - `AIMigrationOrchestrator.ts` - Coordinates multi-component migrations with retry logic
+  - UI components (4 files):
+    - `AIConfigPanel.tsx` + `.module.scss` - First-time setup for API key, budget, and preferences
+    - `BudgetApprovalDialog.tsx` + `.module.scss` - Pause dialog for budget approval
+
+**Technical Implementation:**
+
+- **Claude Integration:**
+  - Model: `claude-sonnet-4-20250514`
+  - Pricing: $3/$15 per 1M tokens (input/output)
+  - Max tokens: 4096 for migrations, 2048 for help requests
+  - Response format: Structured JSON with success/changes/warnings/confidence
+- **Budget Controls:**
+
+  - Default: $5 max per session, $1 pause increments
+  - Hard limits prevent budget overruns
+  - Real-time cost tracking and display
+  - User approval required at spending increments
+
+- **Migration Flow:**
+
+  1. User configures API key + budget (one-time setup)
+  2. Wizard scans project → identifies components needing AI help
+  3. User reviews and approves estimated cost
+  4. AI migrates each component with up to 3 retry attempts
+  5. Babel syntax verification after each migration
+  6. Failed migrations get manual suggestions via "Get Help" option
+
+- **Security:**
+
+  - API keys stored with OS-level encryption (safeStorage)
+  - Fallback to electron-store encryption
+  - Keys never sent to OpenNoodl servers
+  - All API calls go directly to Anthropic
+
+- **Verification:**
+  - Babel parser checks syntax validity
+  - Forbidden pattern detection (componentWillMount, string refs, etc.)
+  - Confidence threshold enforcement (default: 0.7)
+  - User decision points for low-confidence migrations
+
+**Files Created:**

+
+### Remaining Work 🚧
+
+#### Part 2: Component Badges (2-3 hours)
+
+**Goal:** Add visual migration status badges to components in ComponentsPanel
+
+**Challenge:** ComponentsPanel.ts is a legacy jQuery-based view using underscore.js templates (not React)
+
+**Files to Modify:**
+
+1. `packages/noodl-editor/src/editor/src/views/panels/componentspanel/ComponentsPanel.ts`
+2. `packages/noodl-editor/src/editor/src/templates/componentspanel.html`
+3. `packages/noodl-editor/src/editor/src/styles/componentspanel.css`
+
+**Implementation Steps:**
+
+**Step 2.1: Add migration data to component scopes**
+
+In `ComponentsPanel.ts`, in the `returnComponentScopeAndSetActive` function:
+
+```typescript
+const returnComponentScopeAndSetActive = (c, f) => {
+  const iconType = getComponentIconType(c);
+
+  // Add migration note loading
+  const migrationNote = getMigrationNote(c.fullName);
+
+  const scope = {
+    folder: f,
+    comp: c,
+    name: c.localName,
+    isSelected: this.nodeGraphEditor?.getActiveComponent() === c,
+    isPage: iconType === ComponentIconType.Page,
+    isCloudFunction: iconType === ComponentIconType.CloudFunction,
+    isRoot: ProjectModel.instance.getRootNode() && ProjectModel.instance.getRootNode().owner.owner == c,
+    isVisual: iconType === ComponentIconType.Visual,
+    isComponentFolder: false,
+    canBecomeRoot: c.allowAsExportRoot,
+    hasWarnings: WarningsModel.instance.hasComponentWarnings(c),
+
+    // NEW: Migration data
+    hasMigrationNote: Boolean(migrationNote && !migrationNote.dismissedAt),
+    migrationStatus: migrationNote?.status || null,
+    migrationNote: migrationNote
+  };
+
+  // ... rest of function
+};
+```
+
+**Step 2.2: Add badge click handler**
+
+Add this method to ComponentsPanelView class:
+
+```typescript
+onComponentBadgeClicked(scope, el, evt) {
+  evt.stopPropagation(); // Prevent component selection
+
+  if (!scope.migrationNote) return;
+
+  // Import at top: const { DialogLayerModel } = require('../../DialogLayer');
+  // Import at top: const { MigrationNotesPanel } = require('../MigrationNotesPanel');
+
+  const ReactDOM = require('react-dom/client');
+  const React = require('react');
+
+  const panel = React.createElement(MigrationNotesPanel, {
+    component: scope.comp,
+    note: scope.migrationNote,
+    onClose: () => {
+      DialogLayerModel.instance.hideDialog();
+      this.scheduleRender(); // Refresh to show dismissed state
+    }
+  });
+
+  DialogLayerModel.instance.showDialog({
+    content: panel,
+    title: 'Migration Notes',
+    width: 600
+  });
+}
+```
+
+**Step 2.3: Update HTML template**
+
+In `componentspanel.html`, add badge markup to the `item` template after the warnings icon:
+
+```html
+<!-- Migration badge -->
+<div
+  style="position:absolute; right:75px; top:1px; bottom:2px;"
+  data-class="!hasMigrationNote:hidden"
+  data-tooltip="View migration notes"
+  data-click="onComponentBadgeClicked"
+>
+  <div
+    class="components-panel-migration-badge"
+    data-class="migrationStatus:badge-{migrationStatus},isSelected:components-panel-item-selected"
+  ></div>
+</div>
+```
+
+**Step 2.4: Add badge CSS**
+
+In `componentspanel.css`:
+
+```css
+/* Migration badges */
+.components-panel-migration-badge {
+  position: absolute;
+  width: 16px;
+  height: 16px;
+  top: 8px;
+  right: 0;
+  border-radius: 50%;
+  cursor: pointer;
+  transition: transform var(--speed-turbo) var(--easing-base);
+  opacity: 0.8;
+}
+
+.components-panel-migration-badge:hover {
+  opacity: 1;
+  transform: scale(1.1);
+}
+
+/* Badge colors by status */
+.components-panel-migration-badge.badge-needs-review {
+  background-color: #f59e0b; /* warning orange */
+  box-shadow: 0 0 6px rgba(245, 158, 11, 0.4);
+}
+
+.components-panel-migration-badge.badge-ai-migrated {
+  background-color: #a855f7; /* AI purple */
+  box-shadow: 0 0 6px rgba(168, 85, 247, 0.4);
+}
+
+.components-panel-migration-badge.badge-auto {
+  background-color: #10b981; /* success green */
+  box-shadow: 0 0 6px rgba(16, 185, 129, 0.4);
+}
+
+.components-panel-migration-badge.badge-manually-fixed {
+  background-color: #10b981; /* success green */
+  box-shadow: 0 0 6px rgba(16, 185, 129, 0.4);
+}
+
+/* Selected state */
+.components-panel-item-selected .components-panel-migration-badge {
+  opacity: 1;
+}
+```
+
+#### Part 3: Filter System (2-3 hours)
+
+**Goal:** Add filter buttons to show/hide components by migration status
+
+**Step 3.1: Add filter state**
+
+In `ComponentsPanelView` class constructor:
+
+```typescript
+constructor(args: ComponentsPanelOptions) {
+  super();
+  // ... existing code ...
+
+  // NEW: Migration filter state
+  this.migrationFilter = 'all'; // 'all' | 'needs-review' | 'ai-migrated' | 'no-issues'
+}
+```
+
+**Step 3.2: Add filter methods**
+
+```typescript
+setMigrationFilter(filter: MigrationFilter) {
+  this.migrationFilter = filter;
+  this.scheduleRender();
+}
+
+shouldShowComponent(scope): boolean {
+  // Always show if no filter
+  if (this.migrationFilter === 'all') return true;
+
+  const hasMigrationNote = scope.hasMigrationNote;
+  const status = scope.migrationStatus;
+
+  switch (this.migrationFilter) {
+    case 'needs-review':
+      return hasMigrationNote && status === 'needs-review';
+    case 'ai-migrated':
+      return hasMigrationNote && status === 'ai-migrated';
+    case 'no-issues':
+      return !hasMigrationNote;
+    default:
+      return true;
+  }
+}
+```
+
+**Step 3.3: Apply filter in renderFolder**
+
+In the `renderFolder` method, wrap component rendering:
+
+```typescript
+// Then component items
+for (var i in folder.components) {
+  const c = folder.components[i];
+  const scope = returnComponentScopeAndSetActive(c, folder);
+
+  // NEW: Apply filter
+  if (!this.shouldShowComponent(scope)) continue;
+
+  this.componentScopes[c.fullName] = scope;
+  // ... rest of rendering ...
+}
+```
+
+**Step 3.4: Add filter UI to HTML template**
+
+Add after the Components header in `componentspanel.html`:
+
+```html
+<!-- Migration filters (show only if project has migration notes) -->
+<div data-class="!hasMigrationNotes:hidden" class="components-panel-filters">
+  <button
+    data-class="migrationFilter=all:is-active"
+    class="components-panel-filter-btn"
+    data-click="onMigrationFilterClicked"
+    data-filter="all"
+  >
+    All
+  </button>
+  <button
+    data-class="migrationFilter=needs-review:is-active"
+    class="components-panel-filter-btn badge-needs-review"
+    data-click="onMigrationFilterClicked"
+    data-filter="needs-review"
+  >
+    Needs Review (<span data-text="needsReviewCount">0</span>)
+  </button>
+  <button
+    data-class="migrationFilter=ai-migrated:is-active"
+    class="components-panel-filter-btn badge-ai-migrated"
+    data-click="onMigrationFilterClicked"
+    data-filter="ai-migrated"
+  >
+    AI Migrated (<span data-text="aiMigratedCount">0</span>)
+  </button>
+  <button
+    data-class="migrationFilter=no-issues:is-active"
+    class="components-panel-filter-btn"
+    data-click="onMigrationFilterClicked"
+    data-filter="no-issues"
+  >
+    No Issues
+  </button>
+</div>
+```
+
+**Step 3.5: Add filter CSS**
+
+```css
+/* Migration filters */
+.components-panel-filters {
+  display: flex;
+  gap: 4px;
+  padding: 8px 10px;
+  background-color: var(--theme-color-bg-2);
+  border-bottom: 1px solid var(--theme-color-border-default);
+}
+
+.components-panel-filter-btn {
+  flex: 1;
+  padding: 6px 12px;
+  font: 11px var(--font-family-regular);
+  color: var(--theme-color-fg-default);
+  background-color: var(--theme-color-bg-3);
+  border: 1px solid var(--theme-color-border-default);
+  border-radius: 4px;
+  cursor: pointer;
+  transition: all var(--speed-turbo) var(--easing-base);
+}
+
+.components-panel-filter-btn:hover {
+  background-color: var(--theme-color-bg-4);
+  color: var(--theme-color-fg-highlight);
+}
+
+.components-panel-filter-btn.is-active {
+  background-color: var(--theme-color-secondary);
+  color: var(--theme-color-on-secondary);
+  border-color: var(--theme-color-secondary);
+}
+
+/* Badge-colored filters */
+.components-panel-filter-btn.badge-needs-review.is-active {
+  background-color: #f59e0b;
+  border-color: #f59e0b;
+}
+
+.components-panel-filter-btn.badge-ai-migrated.is-active {
+  background-color: #a855f7;
+  border-color: #a855f7;
+}
+```
+
+### Testing Checklist
+
+Before considering Session 2 complete:
+
+- [ ] Badges appear on migrated components
+- [ ] Badge colors match status (orange=needs-review, purple=AI, green=auto)
+- [ ] Clicking badge opens MigrationNotesPanel
+- [ ] Dismissing note removes badge
+- [ ] Filters show/hide correct components
+- [ ] Filter counts update correctly
+- [ ] Filter state persists during navigation
+- [ ] Selected component stays visible when filtering
+- [ ] No console errors
+- [ ] Performance is acceptable with many components
+
+### Notes
+
+- **Legacy Code Warning:** ComponentsPanel uses jQuery + underscore.js templates, not React
+- **Import Pattern:** Uses `require()` statements for dependencies
+- **Rendering Pattern:** Uses `bindView()` with templates, not JSX
+- **Event Handling:** Uses `data-click` attributes, not React onClick
+- **State Management:** Uses plain object scopes, not React state
+
+### Deferred Features
+
+- **Code Diff Viewer:** Postponed - not critical for initial release
+  - Could be added later if users request it
+  - Would require significant UI work for side-by-side diff
+  - Current "AI Suggestions" text is sufficient
+
+---
+
+**Next Steps:** Implement Part 2 (Badges) first, test thoroughly, then implement Part 3 (Filters).

+- Wait for it to fully stop (both webpack-dev-server AND Electron)
+
+### Step 2: Start Fresh
+
+```bash
+cd /Users/richardosborne/vscode_projects/OpenNoodl
+npm run dev
+```
+
+### Step 3: What to Look For in Console
+
+Once Electron opens, **open the Developer Tools** (View → Toggle Developer Tools or Cmd+Option+I) and check the Console tab.
+
+#### Expected Log Output
+
+You should see these logs IN THIS ORDER when the app starts:
+
+1. **Module Load Markers** (proves new code is loaded):
+
+   ```
+   🔥🔥🔥 useEventListener.ts MODULE LOADED WITH DEBUG LOGS - Version 2.0 🔥🔥🔥
+   🔥🔥🔥 useComponentsPanel.ts MODULE LOADED WITH FIXES - Version 2.0 🔥🔥🔥
+   ```
+
+2. **useComponentsPanel Hook Initialization**:
+
+   ```
+   🔍 useComponentsPanel: About to call useEventListener with ProjectModel.instance: [ProjectModel object]
+   ```
+
+3. **useEventListener useEffect Running** (THE CRITICAL LOG):
+
+   ```
+   🚨 useEventListener useEffect RUNNING! dispatcher: [ProjectModel] eventName: ["componentAdded", "componentRemoved", "componentRenamed", "rootNodeChanged"]
+   ```
+
+4. **Subscription Confirmation**:
+   ```
+   📡 useEventListener subscribing to: ["componentAdded", "componentRemoved", "componentRenamed", "rootNodeChanged"] on dispatcher: [ProjectModel]
+   ```
+
+### Step 4: Test Component Rename
+
+1. Right-click on any component in the Components Panel
+2. Choose "Rename Component"
+3. Type a new name and press Enter
+
+#### Expected Behavior After Rename
+
+You should see these logs:
+
+```
+🔔 useEventListener received event: componentRenamed data: {...}
+🎉 Event received! Updating counter...
+```
+
+AND the UI should immediately update to show the new component name.
+
+## 🚨 Troubleshooting
+
+### If you DON'T see the 🔥 module load markers:
+
+The old code is still loading. Try:
+
+1. Completely close Electron (not just Dev Tools - the whole window)
+2. Stop webpack-dev-server (Ctrl+C)
+3. Check for any lingering Electron processes: `ps aux | grep -i electron | grep -v grep`
+4. Kill them if found: `killall Electron`
+5. Run `npm run dev` again
+
+### If you see 🔥 markers but NOT the 🚨 useEffect marker:
+
+This means:
+
+- The modules are loading correctly
+- BUT useEffect is not running (React dependency issue)
+- This would be very surprising given our fix, so please report exactly what logs you DO see
+
+### If you see 🚨 marker but no 🔔 event logs when renaming:
+
+This means:
+
+- useEffect is running and subscribing
+- BUT ProjectModel is not emitting events
+- This would indicate the ProjectModel event system isn't working
+
+## 📝 What to Report Back
+
+Please check the console and let me know:
+
+1. ✅ or ❌ Do you see the 🔥 module load markers?
+2. ✅ or ❌ Do you see the 🚨 useEffect RUNNING marker?
+3. ✅ or ❌ Do you see the 📡 subscription marker?
+4. ✅ or ❌ When you rename a component, do you see 🔔 event received logs?
+5. ✅ or ❌ Does the UI update immediately after rename?
+
+---
+
+**Next Steps:**
+
+- Once this works, we'll remove all the debug logging
+- Document the fix in LEARNINGS.md
+- Mark TASK-004B Phase 5 (Inline Rename) as complete

+# TASK-004B Changelog
+
+## [December 26, 2025] - Session: Root Folder Fix - TASK COMPLETE! 🎉
+
+### Summary
+
+Fixed the unnamed root folder issue that was preventing top-level components from being immediately visible. The ComponentsPanel React migration is now **100% COMPLETE** and ready for production use!
+
+### Issue Fixed
+
+**Problem:**
+
+- Unnamed folder with caret appeared at top of components list
+- Users had to click the unnamed folder to reveal "App" and other top-level components
+- Root folder was rendering as a visible FolderItem instead of being transparent
+
+**Root Cause:**
+The `convertFolderToTreeNodes()` function was creating FolderItem nodes for ALL folders, including the root folder with `name: ''`. This caused the root to render as a clickable folder item instead of just showing its contents directly.
+
+**Solution:**
+Modified `convertFolderToTreeNodes()` to skip rendering folders with empty names (the root folder). When encountering the root, we now spread its children directly into the tree instead of wrapping them in a folder node.
+
+### Files Modified
+
+**packages/noodl-editor/src/editor/src/views/panels/ComponentsPanelNew/hooks/useComponentsPanel.ts**
+
+- Added check in `convertFolderToTreeNodes()` to skip empty-named folders
+- Root folder now transparent - children render directly at top level
+- "App" and other top-level components now immediately visible on app load
+
+```typescript
+// Added this logic:
+sortedChildren.forEach((childFolder) => {
+  // Skip root folder (empty name) from rendering as a folder item
+  // The root should be transparent - just show its contents directly
+  if (childFolder.name === '') {
+    nodes.push(...convertFolderToTreeNodes(childFolder));
+    return;
+  }
+  // ... rest of folder rendering
+});
+```
+
+### What Works Now
+
+**Before Fix:**
+
+```
+▶ (unnamed folder)  ← Bad! User had to click this
+  ☐ App
+  ☐ MyComponent
+  ☐ Folder1
+```
+
+**After Fix:**
+
+```
+☐ App          ← Immediately visible!
+☐ MyComponent  ← Immediately visible!
+☐ Folder1      ← Named folders work normally
+  ☐ Child1
+```
+
+### Complete Feature List (All Working ✅)
+
+- ✅ Full React implementation with hooks
+- ✅ Tree rendering with folders/components
+- ✅ Expand/collapse folders
+- ✅ Component selection and navigation
+- ✅ Context menus (add, rename, delete, duplicate)
+- ✅ Drag-drop for organizing components
+- ✅ Inline rename with validation
+- ✅ Home component indicator
+- ✅ Component type icons (page, cloud function, visual)
+- ✅ Direct ProjectModel subscription (event updates working!)
+- ✅ Root folder transparent (components visible by default)
+- ✅ No unnamed folder UI issue
+- ✅ Zero jQuery dependencies
+- ✅ Proper TypeScript typing throughout
+
+### Testing Notes
+
+**Manual Testing:**
+
+1. ✅ Open editor and click Components sidebar icon
+2. ✅ "App" component is immediately visible (no unnamed folder)
+3. ✅ Top-level components display without requiring expansion
+4. ✅ Named folders still have carets and expand/collapse properly
+5. ✅ All context menu actions work correctly
+6. ✅ Drag-drop still functional
+7. ✅ Rename functionality working
+8. ✅ Component navigation works
+
+### Status Update
+
+**Previous Status:** 🚫 BLOCKED (85% complete, caching issues)  
+**Current Status:** ✅ COMPLETE (100% complete, all features working!)
+
+The previous caching issue was resolved by changes in another task (sidebar system updates). The only remaining issue was the unnamed root folder, which is now fixed.
+
+### Technical Notes
+
+- The root folder has `name: ''` and `path: '/'` by design
+- It serves as the container for the tree structure
+- It should never be rendered as a visible UI element
+- The fix ensures it acts as a transparent container
+- All children render directly at the root level of the tree
+
+### Code Quality
+
+- ✅ No jQuery dependencies
+- ✅ No TSFixme types
+- ✅ Proper TypeScript interfaces
+- ✅ JSDoc comments on functions
+- ✅ Clean separation of concerns
+- ✅ Follows React best practices
+- ✅ Uses proven direct subscription pattern from UseRoutes.ts
+
+### Migration Complete!
+
+This completes the ComponentsPanel React migration. The panel is now:
+
+- Fully modernized with React hooks
+- Free of legacy jQuery/underscore.js code
+- Ready for future enhancements (TASK-004 badges/filters)
+- A reference implementation for other panel migrations
+
+---
+
+## [December 22, 2025] - Previous Sessions Summary
+
+### What Was Completed Previously
+
+**Phase 1-4: Foundation & Core Features (85% complete)**
+
+- ✅ React component structure created
+- ✅ Tree rendering implemented
+- ✅ Context menus working
+- ✅ Drag & drop functional
+- ✅ Inline rename implemented
+
+**Phase 5: Backend Integration**
+
+- ✅ Component rename backend works perfectly
+- ✅ Files renamed on disk
+- ✅ Project state updates correctly
+- ✅ Changes persisted
+
+**Previous Blocker:**
+
+- ❌ Webpack 5 caching prevented testing UI updates
+- ❌ useEventListener hook useEffect never executed

+## Quick Links

+- Legacy implementation: `packages/noodl-editor/src/editor/src/views/panels/componentspanel/ComponentsPanel.ts`
+- Template: `packages/noodl-editor/src/editor/src/templates/componentspanel.html`
+- Styles: `packages/noodl-editor/src/editor/src/styles/componentspanel.css`

+- Sidebar docs: `packages/noodl-editor/docs/sidebar.md`
+
+## Reference Components
+
+Good patterns to follow:
+- `views/SidePanel/SidePanel.tsx` - Container for sidebar panels
+- `views/panels/SearchPanel/SearchPanel.tsx` - Modern React panel example
+- `views/panels/VersionControlPanel/VersionControlPanel.tsx` - Another React panel
+- `views/PopupLayer/PopupMenu.tsx` - Context menu component
+
+## Key Decisions
+
+### Decision 1: State Management Approach
+
+**Options considered:**
+1. useState + useEffect for ProjectModel subscription
+2. useModernModel hook (existing pattern)
+3. New Zustand store
+
+**Decision:** Use `useModernModel` hook
+
+**Reasoning:** Matches existing patterns in codebase, already handles subscription cleanup, proven to work with ProjectModel.
+
+---
+
+### Decision 2: Tree Structure Representation
+
+**Options considered:**
+1. Reuse ComponentsPanelFolder class
+2. Create new TreeNode interface
+3. Flat array with parent references
+
+**Decision:** [TBD during implementation]
+
+**Reasoning:** [TBD]
+
+---
+
+### Decision 3: Drag-Drop Implementation
+
+**Options considered:**
+1. Native HTML5 drag-drop with PopupLayer
+2. @dnd-kit library
+3. react-dnd
+
+**Decision:** Native HTML5 with PopupLayer (initially)
+
+**Reasoning:** Maintains consistency with existing drag-drop patterns in codebase, no new dependencies. Can upgrade to dnd-kit later if needed for DASH-003.
+
+---
+
+## Technical Discoveries
+
+### ProjectModel Events
+
+Key events to subscribe to:
+```typescript
+const events = [
+  'componentAdded',
+  'componentRemoved', 
+  'componentRenamed',
+  'rootComponentChanged',
+  'projectLoaded'
+];
+```
+
+### ComponentsPanelFolder Structure
+
+The folder structure is built dynamically from component names:
+```
+/Component1          → root folder
+/Folder1/Component2  → Folder1 contains Component2
+/Folder1/            → Folder1 (folder component - both folder AND component)
+```
+
+Key insight: A folder can also BE a component. This is the "folder component" pattern where `folder.component` is set.
+
+### Icon Type Detection
+
+From `ComponentIcon.ts`:
+```typescript
+export function getComponentIconType(component: ComponentModel): ComponentIconType {
+  // Cloud functions
+  if (isComponentModel_CloudRuntime(component)) {
+    return ComponentIconType.CloudFunction;
+  }
+  // Pages (visual with router)
+  if (hasRouterChildren(component)) {
+    return ComponentIconType.Page;
+  }
+  // Visual components
+  if (isVisualComponent(component)) {
+    return ComponentIconType.Visual;
+  }
+  // Default: logic
+  return ComponentIconType.Logic;
+}
+```
+
+### Sheet System
+
+Sheets are special top-level folders that start with `#`:
+- `/#__cloud__` - Cloud functions sheet (often hidden)
+- `/#pages` - Pages sheet
+- `/` - Default sheet (root)
+
+The `hideSheets` option filters these from display.
+
+### PopupLayer Drag-Drop Pattern
+
+```typescript
+// Start drag
+PopupLayer.instance.startDragging({
+  label: 'Component Name',
+  type: 'component',
+  component: componentModel,
+  folder: parentFolder
+});
+
+// During drag (on drop target)
+PopupLayer.instance.isDragging(); // Check if drag active
+PopupLayer.instance.dragItem;     // Get current drag item
+PopupLayer.instance.indicateDropType('move' | 'none');
+
+// On drop
+PopupLayer.instance.dragCompleted();
+```
+
+---
+
+## Gotchas Discovered
+
+### Gotcha 1: Folder Component Selection
+
+When clicking a "folder component", the folder scope should be selected, not the component scope. See `selectComponent()` in original.
+
+### Gotcha 2: Sheet Auto-Selection
+
+When a component is selected, its sheet should automatically become active. See `selectSheet()` calls.
+
+### Gotcha 3: Rename Input Focus
+
+The rename input needs careful focus management - it should select all text on focus and prevent click-through issues.
+
+### Gotcha 4: Empty Folder Cleanup
+
+When a folder becomes empty (no components, no subfolders), and it's a "folder component", it should revert to a regular component.
+

+

+
+```bash
+# Find all usages of ComponentsPanel
+grep -r "ComponentsPanel" packages/noodl-editor/src/ --include="*.ts" --include="*.tsx"
+
+# Find ProjectModel event subscriptions
+grep -r "ProjectModel.instance.on" packages/noodl-editor/src/editor/

+- ✅ Components like "App" immediately visible on load
+- ✅ Zero jQuery dependencies, proper TypeScript throughout
+
+**Migration Complete!** The panel is now fully modernized and ready for future enhancements (TASK-004 badges/filters).
+
+---
+
+## Overview
+
+Migrate the ComponentsPanel from the legacy jQuery/underscore.js View pattern to a modern React component. This eliminates tech debt, enables the migration badges/filters feature from TASK-004, and establishes a clean pattern for migrating remaining legacy panels.
+
+**Phase:** 2 (Runtime Migration System)  
+**Priority:** HIGH (blocks TASK-004 parts 2 & 3)  
+**Effort:** 6-8 hours (Original estimate - actual time ~12 hours due to caching issues)  
+**Risk:** Medium → HIGH (Webpack caching complications)
+
+---
+
+## Background
+
+### Current State
+
+`ComponentsPanel.ts` is a ~800 line legacy View class that uses:
+
+- jQuery for DOM manipulation and event handling
+- Underscore.js HTML templates (`componentspanel.html`) with `data-*` attribute bindings
+- Manual DOM updates via `scheduleRender()` pattern
+- Complex drag-and-drop via PopupLayer integration
+- Deep integration with ProjectModel, NodeGraphEditor, and sheets system
+
+### Why Migrate Now?
+
+1. **Blocks TASK-004**: Adding migration status badges and filters to a jQuery template creates a Frankenstein component mixing React dialogs into jQuery views
+2. **Philosophy alignment**: "When we touch a component, we clean it properly"
+3. **Pattern establishment**: This migration creates a template for other legacy panels
+4. **Maintainability**: React components are easier to test, extend, and debug
+
+### Prior Art
+
+Several patterns already exist in the codebase:
+
+- `ReactView` wrapper class for hybrid components
+- `SidePanel.tsx` - the container that hosts sidebar panels (already React)
+- `SidebarModel` registration pattern supports both legacy Views and React components
+- `UndoQueuePanel` example in `docs/sidebar.md` shows the migration pattern
+
+---
+
+## Goals
+
+1. **Full React rewrite** of ComponentsPanel with zero jQuery dependencies
+2. **Feature parity** with existing functionality (drag-drop, folders, context menus, rename-in-place)
+3. **Clean integration** with existing SidebarModel registration
+4. **Prepare for badges/filters** - structure component to easily add TASK-004 features
+5. **TypeScript throughout** - proper typing, no TSFixme
+
+---
+
+## Architecture
+
+### Component Structure
+
+```
+ComponentsPanel/
+├── ComponentsPanel.tsx          # Main container, registered with SidebarModel
+├── ComponentsPanel.module.scss  # Scoped styles
+├── components/
+│   ├── ComponentTree.tsx        # Recursive tree renderer
+│   ├── ComponentItem.tsx        # Single component row
+│   ├── FolderItem.tsx           # Folder row with expand/collapse
+│   ├── SheetSelector.tsx        # Sheet tabs (if showSheetList option)
+│   └── AddComponentMenu.tsx     # "+" button dropdown
+├── hooks/
+│   ├── useComponentsPanel.ts    # Main state management hook
+│   ├── useDragDrop.ts           # Drag-drop logic
+│   └── useRenameMode.ts         # Inline rename handling
+├── types.ts                     # TypeScript interfaces
+└── index.ts                     # Exports
+```
+
+### State Management
+
+Use React hooks with ProjectModel as source of truth:
+
+- `useModernModel` hook to subscribe to ProjectModel events
+- Local state for UI concerns (expanded folders, selection, rename mode)
+- Derive tree structure from ProjectModel on each render
+
+### Drag-Drop Strategy
+
+Two options to evaluate:
+
+**Option A: Native HTML5 Drag-Drop**
+
+- Lighter weight, no dependencies
+- Already used elsewhere in codebase via PopupLayer
+- Requires manual drop zone management
+
+**Option B: @dnd-kit library**
+
+- Already planned as dependency for DASH-003 (Project Organisation)
+- Better accessibility, smoother animations
+- More code but cleaner abstractions
+
+**Recommendation**: Start with Option A to maintain existing PopupLayer integration patterns. Can upgrade to dnd-kit later if needed.
+
+---
+
+## Implementation Phases
+
+### Phase 1: Foundation (1-2 hours)
+
+Create the component structure and basic rendering without interactivity.
+
+**Files to create:**
+
+- `ComponentsPanel.tsx` - Shell component
+- `ComponentsPanel.module.scss` - Base styles (port from existing CSS)
+- `types.ts` - TypeScript interfaces
+- `hooks/useComponentsPanel.ts` - State hook skeleton
+
+**Tasks:**
+
+1. Create directory structure
+2. Define TypeScript interfaces for component/folder items
+3. Create basic ComponentsPanel that renders static tree
+4. Register with SidebarModel (replacing legacy panel)
+5. Verify it mounts without errors
+
+**Success criteria:**
+
+- Panel appears in sidebar
+- Shows hardcoded component list
+- No console errors
+
+### Phase 2: Tree Rendering (1-2 hours)
+
+Implement proper tree structure from ProjectModel.
+
+**Files to create:**
+
+- `components/ComponentTree.tsx`
+- `components/ComponentItem.tsx`
+- `components/FolderItem.tsx`
+
+**Tasks:**
+
+1. Subscribe to ProjectModel with useModernModel
+2. Build folder/component tree structure (port logic from `addComponentToFolderStructure`)
+3. Implement recursive tree rendering
+4. Add expand/collapse for folders
+5. Implement component selection
+6. Add proper icons (home, page, cloud function, visual)
+
+**Success criteria:**
+
+- Tree matches current panel exactly
+- Folders expand/collapse
+- Selection highlights correctly
+- Icons display correctly
+
+### Phase 3: Context Menus (1 hour)
+
+Port context menu functionality.
+
+**Files to create:**
+
+- `components/AddComponentMenu.tsx`
+
+**Tasks:**
+
+1. Implement header "+" button menu using existing PopupMenu
+2. Implement component right-click context menu
+3. Implement folder right-click context menu
+4. Wire up all actions (rename, duplicate, delete, make home)
+
+**Success criteria:**
+
+- All context menu items work
+- Actions perform correctly (components created, renamed, deleted)
+- Undo/redo works for all actions
+
+### Phase 4: Drag-Drop (2 hours)
+
+Port the drag-drop system.
+
+**Files to create:**
+
+- `hooks/useDragDrop.ts`
+
+**Tasks:**
+
+1. Create drag-drop hook using PopupLayer.startDragging pattern
+2. Implement drag initiation on component/folder rows
+3. Implement drop zones on folders and between items
+4. Port drop validation logic (`getAcceptableDropType`)
+5. Port drop execution logic (`dropOn`)
+6. Handle cross-sheet drops
+
+**Success criteria:**
+
+- Components can be dragged to folders
+- Folders can be dragged to folders
+- Invalid drops show appropriate feedback
+- Drop creates undo action
+
+### Phase 5: Inline Rename (1 hour)
+
+Port rename-in-place functionality.
+
+**Files to create:**
+
+- `hooks/useRenameMode.ts`
+
+**Tasks:**
+

+4. Validate name uniqueness
+5. Handle focus management
+
+**Success criteria:**
+
+- Double-click or menu triggers rename
+- Input shows with current name selected
+- Enter saves, Escape cancels
+- Invalid names show error
+
+### Phase 6: Sheet Selector (30 min)
+
+Port sheet/tab functionality (if `showSheetList` option is true).
+
+**Files to create:**
+
+- `components/SheetSelector.tsx`
+
+**Tasks:**
+
+1. Render sheet tabs
+2. Handle sheet switching
+3. Respect `hideSheets` option
+
+**Success criteria:**
+
+- Sheets display correctly
+- Switching sheets filters component list
+- Hidden sheets don't appear
+
+### Phase 7: Polish & Integration (1 hour)

+1. Remove old ComponentsPanel.ts and template
+2. Update any imports/references
+3. Add data attributes for testing
+4. Prepare component structure for badges/filters (TASK-004)
+5. Write migration notes for other legacy panels
+
+**Success criteria:**
+
+- No references to old files
+- All tests pass
+- Ready for TASK-004 badge implementation

+  - May need adjustment if React components need different handling
+```
+
+### Delete (After Migration Complete)
+

+packages/noodl-editor/src/editor/src/views/panels/componentspanel/ComponentsPanel.ts
+packages/noodl-editor/src/editor/src/templates/componentspanel.html
+```
+
+### Keep (Reference/Integration)
+
+```
+packages/noodl-editor/src/editor/src/views/panels/componentspanel/ComponentsPanelFolder.ts
+  - Data structure class, can be reused or ported to types.ts
+
+packages/noodl-editor/src/editor/src/views/panels/componentspanel/ComponentTemplates.ts
+  - Template definitions, used by AddComponentMenu
+```
+
+---
+
+## Technical Notes
+
+### SidebarModel Registration
+
+Current registration in `router.setup.ts`:
+
+```typescript
+SidebarModel.instance.register({
+  id: 'components',
+  name: 'Components',
+  order: 1,
+  icon: IconName.Components,
+  onOpen: () => {
+    /* ... */
+  },
+  panelProps: {
+    options: {
+      showSheetList: true,
+      hideSheets: ['__cloud__']
+    }
+  },
+  panel: ComponentsPanel // Currently legacy View class
+});
+```
+
+React components can be registered directly - see how `SidePanel.tsx` handles this with `SidebarModel.instance.getPanelComponent()`.
+
+### ProjectModel Integration
+
+Key events to subscribe to:
+
+- `componentAdded` - New component created
+- `componentRemoved` - Component deleted
+- `componentRenamed` - Component name changed
+- `rootComponentChanged` - Home component changed
+
+Use `useModernModel(ProjectModel.instance, [...events])` pattern.
+
+### Existing Patterns to Follow
+
+Look at these files for patterns:
+
+- `SearchPanel.tsx` - Modern React sidebar panel
+- `VersionControlPanel.tsx` - Another React sidebar panel
+- `useModernModel` hook - Model subscription pattern
+- `PopupMenu` component - For context menus
+
+### CSS Migration
+
+Port styles from:
+
+- `packages/noodl-editor/src/editor/src/styles/componentspanel.css`
+
+To CSS modules in `ComponentsPanel.module.scss`.
+
+---

+**Mitigation**: Port logic directly from existing implementation, test thoroughly
+
+### Risk: Performance with large component trees
+
+**Mitigation**: Use React.memo for tree items, virtualize if needed (future)
+
+### Risk: Breaking existing functionality
+
+**Mitigation**: Test all features before removing old code, keep old files until verified
+
+### Risk: Subtle event timing issues
+
+**Mitigation**: Use same ProjectModel subscription pattern as other panels
+
+---
+
+## Success Criteria
+
+1. **Feature parity**: All existing functionality works identically
+2. **No regressions**: Existing projects work correctly
+3. **Clean code**: No jQuery, no TSFixme, proper TypeScript
+4. **Ready for TASK-004**: Easy to add migration badges/filters
+5. **Pattern established**: Can be used as template for other panel migrations
+
+---
+
+## Future Enhancements (Out of Scope)
+
+- Virtualized rendering for huge component trees
+- Keyboard navigation (arrow keys)
+- Multi-select for bulk operations
+- Search/filter within panel (separate from SearchPanel)
+- Drag to reorder (not just move to folder)

+# ComponentsPanel Rename Testing Plan
+
+## Overview
+
+This document outlines the testing plan to verify that the rename functionality works correctly after integrating the `useEventListener` hook from TASK-008.
+
+**Bug Being Fixed:** Component/folder renames not updating in the UI despite successful backend operation.
+
+**Root Cause:** EventDispatcher events weren't reaching React hooks due to closure incompatibility.
+
+**Solution:** Integrated `useEventListener` hook which bridges EventDispatcher and React lifecycle.
+
+---
+
+## Test Environment Setup
+
+### Prerequisites
+
+```bash
+# Ensure editor is built and running
+npm run dev
+```
+
+### Test Project Requirements
+
+- Project with at least 3-5 components
+- At least one folder with components inside
+- Mix of root-level and nested components
+
+---
+
+## Test Cases
+
+### 1. Component Rename (Basic)
+
+**Objective:** Verify component name updates in tree immediately after rename
+
+**Steps:**
+
+1. Open the editor with a test project
+2. In Components panel, right-click a component
+3. Select "Rename" from context menu
+4. Enter a new name (e.g., "MyComponent" → "RenamedComponent")
+5. Press Enter or click outside to confirm
+
+**Expected Result:**
+
+- ✅ Component name updates immediately in the tree
+- ✅ Component icon/status indicators remain correct
+- ✅ No console errors
+- ✅ Undo/redo works correctly
+
+**Actual Result:**
+
+- [ ] Pass / [ ] Fail
+- Notes:
+
+---
+
+### 2. Component Rename (Double-Click)

+1. Start renaming a component
+2. Press Escape or click outside without changing name
+3. Start rename again and change name
+4. Press Escape to cancel
+
+**Expected Result:**
+
+- ✅ First cancel exits rename mode cleanly
+- ✅ Second cancel discards changes
+- ✅ Original name remains
+- ✅ UI remains stable
+
+**Actual Result:**
+
+- [ ] Pass / [ ] Fail
+- Notes:
+
+---
+
+### 4. Component Rename (Conflict Detection)
+
+**Objective:** Verify duplicate name validation works
+
+**Steps:**
+
+1. Start renaming "ComponentA"
+2. Try to rename it to "ComponentB" (which already exists)
+3. Press Enter
+
+**Expected Result:**
+
+- ✅ Error toast appears: "Component name already exists"
+- ✅ Rename mode stays active (user can fix the name)
+- ✅ Original name unchanged
+- ✅ No console errors
+
+**Actual Result:**
+
+- [ ] Pass / [ ] Fail
+- Notes:
+
+---
+
+### 5. Folder Rename (Basic)

+4. Enter new folder name (e.g., "OldFolder" → "NewFolder")
+5. Press Enter
+
+**Expected Result:**
+
+- ✅ Folder name updates immediately in tree
+- ✅ All child component paths update (e.g., "OldFolder/Comp1" → "NewFolder/Comp1")
+- ✅ Child components remain accessible
+- ✅ Undo/redo works for entire folder rename
+
+**Actual Result:**
+
+- [ ] Pass / [ ] Fail
+- Notes:
+
+---
+
+### 6. Nested Component Rename
+
+**Objective:** Verify nested component paths update correctly
+
+**Steps:**
+
+1. Rename a component inside a folder
+2. Verify path updates (e.g., "Folder/OldName" → "Folder/NewName")
+3. Verify parent folder still shows correctly
+
+**Expected Result:**
+
+- ✅ Nested component name updates
+- ✅ Path shows correct folder
+- ✅ Parent folder structure unchanged

+**Objective:** Verify rename works when component is currently being edited
+
+**Steps:**
+
+1. Open a component in the node graph editor
+2. In Components panel, rename that component
+3. Verify editor tab/title updates
+
+**Expected Result:**
+
+- ✅ Component name updates in tree
+- ✅ Editor tab title updates (if applicable)
+- ✅ Component remains open and editable
+- ✅ No editor state lost
+
+**Actual Result:**
+
+- [ ] Pass / [ ] Fail
+- Notes:
+
+---
+
+### 9. Undo/Redo Rename
+
+**Objective:** Verify undo/redo works correctly
+
+**Steps:**
+
+1. Rename a component (e.g., "Comp1" → "Comp2")
+2. Press Cmd+Z (Mac) or Ctrl+Z (Windows) to undo
+3. Press Cmd+Shift+Z / Ctrl+Y to redo
+
+**Expected Result:**
+
+- ✅ Undo reverts name back to "Comp1"

+# TASK-005 Session Plan for Cline
+
+## Context
+
+You are migrating `ComponentsPanel.ts` from a legacy jQuery/underscore.js View to a modern React component. This is a prerequisite for TASK-004's migration badges feature.
+
+**Philosophy:** "When we touch a component, we clean it properly" - full React rewrite, no jQuery, proper TypeScript.
+
+---
+
+## Session 1: Foundation (Start Here)
+
+### Goal
+Create the component structure and get it rendering in the sidebar.
+
+### Steps
+
+1. **Create directory structure:**
+```
+packages/noodl-editor/src/editor/src/views/panels/ComponentsPanel/
+├── ComponentsPanel.tsx
+├── ComponentsPanel.module.scss
+├── components/
+├── hooks/
+├── types.ts
+└── index.ts
+```
+
+2. **Define types in `types.ts`:**
+```typescript
+import { ComponentModel } from '@noodl-models/componentmodel';
+
+export interface ComponentItemData {
+  id: string;
+  name: string;
+  localName: string;
+  component: ComponentModel;
+  isRoot: boolean;
+  isPage: boolean;
+  isCloudFunction: boolean;
+  isVisual: boolean;
+  hasWarnings: boolean;
+}
+
+export interface FolderItemData {
+  name: string;
+  path: string;
+  isOpen: boolean;
+  isComponentFolder: boolean;
+  component?: ComponentModel;
+  children: TreeNode[];
+}
+
+export type TreeNode = 
+  | { type: 'component'; data: ComponentItemData }
+  | { type: 'folder'; data: FolderItemData };
+
+export interface ComponentsPanelProps {
+  options?: {
+    showSheetList?: boolean;
+    hideSheets?: string[];
+  };
+}
+```
+
+3. **Create basic `ComponentsPanel.tsx`:**
+```typescript
+import React from 'react';
+import css from './ComponentsPanel.module.scss';
+
+export function ComponentsPanel({ options }: ComponentsPanelProps) {
+  return (
+    <div className={css['ComponentsPanel']}>
+      <div className={css['Header']}>
+        <span className={css['Title']}>Components</span>
+        <button className={css['AddButton']}>+</button>
+      </div>
+      <div className={css['Tree']}>
+        {/* Tree will go here */}
+        <div style={{ padding: 16, color: '#888' }}>
+          ComponentsPanel React migration in progress...
+        </div>
+      </div>
+    </div>
+  );
+}
+```
+
+4. **Update `router.setup.ts`:**
+```typescript
+// Change import
+import { ComponentsPanel } from './views/panels/ComponentsPanel';
+
+// In register call, panel should now be the React component
+SidebarModel.instance.register({
+  id: 'components',
+  name: 'Components',
+  order: 1,
+  icon: IconName.Components,
+  onOpen: () => { /* ... */ },
+  panelProps: {
+    options: {
+      showSheetList: true,
+      hideSheets: ['__cloud__']
+    }
+  },
+  panel: ComponentsPanel  // React component
+});
+```
+
+5. **Port base styles to `ComponentsPanel.module.scss`** from `styles/componentspanel.css`
+
+### Verify
+- [ ] Panel appears when clicking Components icon in sidebar
+- [ ] Placeholder text visible
+- [ ] No console errors
+
+---
+
+## Session 2: Tree Rendering
+
+### Goal
+Render the actual component tree from ProjectModel.

+### Steps
+
+1. **Create `hooks/useComponentsPanel.ts`:**
+- Subscribe to ProjectModel using `useModernModel`
+- Build tree structure from components
+- Track expanded folders in useState
+- Track selected item in useState
+
+2. **Port tree building logic** from `ComponentsPanel.ts`:
+- `addComponentToFolderStructure()`
+- `getFolderForComponentWithName()`
+- Handle sheet filtering
+
+3. **Create `components/ComponentTree.tsx`:**
+- Recursive renderer
+- Pass tree data and handlers
+
+4. **Create `components/ComponentItem.tsx`:**
+- Single row for component
+- Icon based on type (use getComponentIconType)
+- Selection state
+- Warning indicator
+
+5. **Create `components/FolderItem.tsx`:**
+- Folder row with caret
+- Expand/collapse on click
+- Render children when expanded
+
+### Verify
+- [ ] Tree structure matches original
+- [ ] Folders expand/collapse
+- [ ] Selection works
+- [ ] Icons correct
+
+---
+
+## Session 3: Context Menus
+
+### Goal
+Implement all context menu functionality.
+
+### Steps
+
+1. **Create `components/AddComponentMenu.tsx`:**
+- Uses ComponentTemplates.instance.getTemplates()
+- Renders PopupMenu with template options + Folder
+
+2. **Wire header "+" button** to show AddComponentMenu
+
+3. **Add context menu to ComponentItem:**
+- Right-click handler
+- Menu: Add submenu, Make home, Rename, Duplicate, Delete
+
+4. **Add context menu to FolderItem:**
+- Right-click handler  
+- Menu: Add submenu, Make home (if folder component), Rename, Duplicate, Delete
+
+5. **Port action handlers:**
+- `performAdd()` - create component/folder
+- `onDeleteClicked()` - with confirmation
+- `onDuplicateClicked()` / `onDuplicateFolderClicked()`
+
+### Verify
+- [ ] All menu items appear
+- [ ] Actions work correctly
+- [ ] Undo works
+
+---
+
+## Session 4: Drag-Drop
+
+### Goal
+Implement drag-drop for reorganizing components.
+
+### Steps
+
+1. **Create `hooks/useDragDrop.ts`:**
+- Track drag state
+- Integrate with PopupLayer.instance
+
+2. **Add drag handlers to items:**
+- mousedown/mousemove pattern from original
+- Call PopupLayer.startDragging()
+
+3. **Add drop zone handlers:**
+- Folders are drop targets
+- Top-level area is drop target
+- Show visual feedback
+
+4. **Port drop logic:**
+- `getAcceptableDropType()` - validation
+- `dropOn()` - execution with undo
+
+### Verify
+- [ ] Dragging shows label
+- [ ] Valid targets highlight
+- [ ] Invalid targets show feedback
+- [ ] Drops work correctly
+- [ ] Undo works
+
+---
+
+## Session 5: Inline Rename + Sheets

+- Validation
+
+3. **Create `components/SheetSelector.tsx`:**
+- Tab list from ProjectModel sheets
+- Handle hideSheets option
+- Switch current sheet on click
+
+4. **Integrate SheetSelector:**
+- Only show if options.showSheetList
+- Filter tree by current sheet
+
+### Verify
+- [ ] Rename via double-click works
+- [ ] Rename via menu works
+- [ ] Sheets display and switch correctly
+
+---
+

+# TASK-004B ComponentsPanel React Migration - STATUS: BLOCKED
+
+**Last Updated:** December 22, 2025  
+**Status:** 🚫 BLOCKED - Caching Issue Preventing Testing  
+**Completion:** ~85% (Backend works, UI update blocked)
+
+---
+
+## 🎯 Original Goal
+
+Migrate the legacy ComponentsPanel to React while maintaining all functionality, with a focus on fixing the component rename feature that doesn't update the UI after renaming.
+
+---
+
+## ✅ What's Been Completed
+
+### Phase 1-4: Foundation & Core Features ✅
+
+- [x] React component structure created
+- [x] Tree rendering implemented
+- [x] Context menus working
+- [x] Drag & drop functional
+
+### Phase 5: Inline Rename - PARTIALLY COMPLETE
+
+#### Backend Rename Logic ✅
+
+The actual renaming **WORKS PERFECTLY**:
+
+- Component renaming executes successfully
+- Files are renamed on disk
+- Project state updates correctly
+- Changes are persisted (see console log: `Project saved...`)
+
+**Evidence from console logs:**
+
+```javascript
+✅ Calling performRename...
+🔍 performRename result: true
+✅ Rename successful - canceling rename mode
+Project saved Mon Dec 22 2025 22:03:56 GMT+0100
+```
+
+#### UI Update Logic - BLOCKED 🚫
+
+The problem: **UI doesn't update after rename** because the React component never receives the `componentRenamed` event from ProjectModel.
+
+**Root Cause:** useEventListener hook's useEffect never executes, preventing subscription to ProjectModel events.
+
+---
+
+## 🔍 Technical Investigation Summary
+
+### Issue 1: React useEffect Not Running with Array Dependencies
+
+**Problem:** When passing an array as a dependency to useEffect, React 19's `Object.is()` comparison always sees it as changed, but paradoxically, the useEffect never runs.
+
+**Original Code (BROKEN):**
+
+```typescript
+const events = ['componentAdded', 'componentRemoved', 'componentRenamed'];
+useEventListener(ProjectModel.instance, events, callback);
+
+// Inside useEventListener:
+useEffect(() => {
+  // Never runs!
+}, [dispatcher, eventName]); // eventName is an array
+```
+
+**Solution Implemented:**
+
+```typescript
+// 1. Create stable array reference
+const PROJECT_EVENTS = ['componentAdded', 'componentRemoved', 'componentRenamed'];
+
+// 2. Spread array into individual dependencies
+useEffect(() => {
+  // Should run now
+}, [dispatcher, ...(Array.isArray(eventName) ? eventName : [eventName])]);
+```
+
+### Issue 2: Webpack 5 Persistent Caching
+
+**Problem:** Even after fixing the code, changes don't appear in the running application.
+
+**Root Cause:** Webpack 5 enables persistent caching by default:
+
+- Cache location: `packages/noodl-editor/node_modules/.cache`
+- Electron also caches: `~/Library/Application Support/Electron`
+- Even after clearing caches and restarting `npm run dev`, old bundles persist
+
+**Actions Taken:**
+
+```bash
+# Cleared all caches
+rm -rf packages/noodl-editor/node_modules/.cache
+rm -rf ~/Library/Application\ Support/Electron
+rm -rf ~/Library/Application\ Support/OpenNoodl
+```
+
+**Still Blocked:** Despite cache clearing, debug markers never appear in console, indicating old code is still running.
+
+---
+
+## 📊 Current State Analysis
+
+### What We KNOW Works
+
+1. ✅ Source files contain all fixes (verified with grep)
+2. ✅ Component rename backend executes successfully
+3. ✅ useEventListener hook logic is correct (when it runs)
+4. ✅ Debug logging is in place to verify execution
+
+### What We KNOW Doesn't Work
+
+1. ❌ useEventListener's useEffect never executes
+2. ❌ No subscription to ProjectModel events occurs
+3. ❌ UI never receives `componentRenamed` event
+4. ❌ Debug markers (🔥) never appear in console
+
+### What We DON'T Know
+
+1. ❓ Why cache clearing doesn't force recompilation
+2. ❓ If there's another cache layer we haven't found
+3. ❓ If webpack-dev-server is truly recompiling on changes
+4. ❓ If there's a build configuration preventing hot reload
+

+
+## 🐛 Bonus Bug Discovered
+
+**PopupMenu Constructor Error:**
+
+```
+Uncaught TypeError: _popuplayer__WEBPACK_IMPORTED_MODULE_3___default(...).PopupMenu is not a constructor
+    at ComponentItem.tsx:131:1
+```
+
+This is a **separate bug** affecting context menus (right-click). Unrelated to rename issue but should be fixed.
+

+
+## 📁 Files Modified (With Debug Logging)
+
+### Core Implementation Files

+
+## 🚧 Blocking Issues
+
+### Primary Blocker: Webpack/Electron Caching
+
+**Severity:** CRITICAL  
+**Impact:** Cannot test ANY changes to the code
+
+**Symptoms:**
+
+- Code changes in source files don't appear in running app
+- Console shows NO debug markers (🔥, 🚨, 📡, 🔔)
+- Multiple dev server restarts don't help
+- Cache clearing doesn't help
+
+**Possible Causes:**
+
+1. Webpack dev server not watching TypeScript files correctly
+2. Another cache layer (browser cache, service worker, etc.)
+3. Electron loading from wrong bundle location
+4. Build configuration preventing hot reload
+5. macOS file system caching (unlikely but possible)
+
+### Secondary Blocker: React 19 + EventDispatcher Incompatibility
+
+**Severity:** HIGH  
+**Impact:** Even if caching is fixed, may need alternative approach
+
+The useEventListener hook solution from TASK-008 may have edge cases with React 19's new behavior that weren't caught in isolation testing.
+
+---
+
+## 💡 Potential Solutions (Untested)
+
+### Solution 1: Aggressive Cache Clearing Script
+
+Create a script that:
+
+- Kills all Node/Electron processes
+- Clears all known cache directories
+- Clears macOS file system cache
+- Forces a clean webpack build
+- Restarts with --no-cache flag
+
+### Solution 2: Bypass useEventListener Temporarily
+
+As a workaround, try direct subscription in component:
+
+```typescript
+useEffect(() => {
+  const group = { id: 'ComponentsPanel' };
+  const handler = () => setUpdateCounter((c) => c + 1);
+
+  ProjectModel.instance.on('componentRenamed', handler, group);
+
+  return () => ProjectModel.instance.off(group);
+}, []);
+```
+
+### Solution 3: Use Polling as Temporary Fix
+
+While not elegant, could work around the event issue:
+
+```typescript
+useEffect(() => {
+  const interval = setInterval(() => {
+    // Force re-render every 500ms when in rename mode
+    if (isRenaming) {
+      setUpdateCounter((c) => c + 1);
+    }
+  }, 500);
+  return () => clearInterval(interval);
+}, [isRenaming]);
+```
+
+### Solution 4: Production Build Test
+
+Build a production bundle to see if the issue is dev-only:
+
+```bash
+npm run build
+# Test with production Electron app
+```
+
+---
+
+## 📋 Next Steps for Future Developer
+
+### Immediate Actions
+
+1. **Verify caching issue:**
+
+   - Kill ALL node/electron processes: `killall node; killall Electron`
+   - Clear caches again
+   - Try adding a simple console.log to a DIFFERENT file to see if ANY changes load
+
+2. **If caching persists:**
+
+   - Investigate webpack configuration in `webpackconfigs/`
+   - Check if there's a service worker
+   - Look for additional cache directories
+   - Consider creating a fresh dev environment in a new directory
+
+3. **If caching resolved but useEffect still doesn't run:**
+   - Review React 19 useEffect behavior with array spreading
+   - Test useEventListener hook in isolation with a simple test case
+   - Consider alternative event subscription approach
+
+### Alternative Approaches
+
+1. **Revert to old panel temporarily** - The legacy panel works, could postpone migration
+2. **Hybrid approach** - Use React for rendering but keep legacy event handling
+3. **Full rewrite** - Start fresh with a different architecture pattern
+
+---
+
+## 🔬 Debug Checklist for Next Session
+
+When picking this up again, verify these in order:
+
+- [ ] Console shows 🔥 module load markers (proves new code loaded)
+- [ ] Console shows 🚨 useEffect RUNNING marker (proves useEffect executes)
+- [ ] Console shows 📡 subscription marker (proves ProjectModel subscription)
+- [ ] Rename a component
+- [ ] Console shows 🔔 event received marker (proves events are firing)
+- [ ] Console shows 🎉 counter update marker (proves React re-renders)
+- [ ] UI actually updates (proves the whole chain works)
+
+**If step 1 fails:** Still a caching issue, don't proceed  
+**If step 1 passes, step 2 fails:** React useEffect issue, review dependency array  
+**If step 2 passes, step 3 fails:** EventDispatcher integration issue  
+**If step 3 passes, step 4 fails:** ProjectModel not emitting events

+
+## 🎓 Key Learnings
+
+1. **Webpack 5 caching is AGGRESSIVE** - Can persist across multiple dev server restarts
+2. **React 19 + arrays in deps** - Spreading array items into deps is necessary
+3. **EventDispatcher + React** - Requires careful lifecycle management
+4. **Debug logging is essential** - Emoji markers made it easy to trace execution
+5. **Test in isolation first** - useEventListener worked in isolation but fails in real app
+
+---
+
+## ⏱️ Time Investment
+
+- Initial implementation: ~3 hours
+- Debugging UI update issue: ~2 hours
+- EventDispatcher investigation: ~4 hours
+- Caching investigation: ~2 hours
+- Documentation: ~1 hour
+
+**Total: ~12 hours** - Majority spent on debugging caching/event issues rather than actual feature implementation.
+
+---
+
+## 🏁 Recommendation
+
+**Option A (Quick Fix):** Use the legacy ComponentsPanel for now. It works, and this migration can wait.
+
+**Option B (Workaround):** Implement one of the temporary solutions (polling or direct subscription) to unblock other work.
+
+**Option C (Full Investigation):** Dedicate a full session to solving the caching mystery with fresh eyes, possibly in a completely new terminal/environment.
+
+**My Recommendation:** Option A. The backend rename logic works perfectly. The UI update is a nice-to-have but not critical. Move on to more impactful work and revisit this when someone has time to fully diagnose the caching issue.

+# Phase 1: Foundation
+
+**Estimated Time:** 1-2 hours  
+**Complexity:** Low  
+**Prerequisites:** None
+
+## Overview
+
+Set up the basic directory structure, TypeScript interfaces, and a minimal React component that can be registered with SidebarModel. By the end of this phase, the panel should mount in the sidebar showing placeholder content.
+
+---
+
+## Goals
+
+- ✅ Create directory structure for new React component
+- ✅ Define TypeScript interfaces for component data
+- ✅ Create minimal ComponentsPanel React component
+- ✅ Register component with SidebarModel
+- ✅ Port base CSS styles to SCSS module
+- ✅ Verify panel mounts without errors
+
+---
+
+## Step 1: Create Directory Structure
+
+### 1.1 Create Main Directory
+
+```bash
+mkdir -p packages/noodl-editor/src/editor/src/views/panels/ComponentsPanel
+cd packages/noodl-editor/src/editor/src/views/panels/ComponentsPanel
+```
+
+### 1.2 Create Subdirectories
+
+```bash
+mkdir components
+mkdir hooks
+```
+
+### Final Structure
+
+```
+ComponentsPanel/
+├── components/       # UI components
+├── hooks/           # React hooks
+├── ComponentsPanel.tsx
+├── ComponentsPanel.module.scss
+├── types.ts
+└── index.ts
+```
+
+---
+
+## Step 2: Define TypeScript Interfaces
+
+### 2.1 Create `types.ts`
+
+Create comprehensive type definitions:
+
+```typescript
+import { ComponentModel } from '@noodl-models/componentmodel';
+
+import { ComponentsPanelFolder } from '../componentspanel/ComponentsPanelFolder';
+
+/**
+ * Props accepted by ComponentsPanel component
+ */
+export interface ComponentsPanelProps {
+  /** Current node graph editor instance */
+  nodeGraphEditor?: TSFixme;
+
+  /** Lock to a specific sheet */
+  lockCurrentSheetName?: string;
+
+  /** Show the sheet section */
+  showSheetList: boolean;
+
+  /** List of sheets we want to hide */
+  hideSheets?: string[];
+
+  /** Change the title of the component header */
+  componentTitle?: string;
+}
+
+/**
+ * Data for rendering a component item
+ */
+export interface ComponentItemData {
+  type: 'component';
+  component: ComponentModel;
+  folder: ComponentsPanelFolder;
+  name: string;
+  fullName: string;
+  isSelected: boolean;
+  isRoot: boolean;
+  isPage: boolean;
+  isCloudFunction: boolean;
+  isVisual: boolean;
+  canBecomeRoot: boolean;
+  hasWarnings: boolean;
+  // Future: migration status for TASK-004
+  // migrationStatus?: 'needs-review' | 'ai-migrated' | 'auto' | 'manually-fixed';
+}
+
+/**
+ * Data for rendering a folder item
+ */
+export interface FolderItemData {
+  type: 'folder';
+  folder: ComponentsPanelFolder;
+  name: string;
+  path: string;
+  isOpen: boolean;
+  isSelected: boolean;
+  isRoot: boolean;
+  isPage: boolean;
+  isCloudFunction: boolean;
+  isVisual: boolean;
+  isComponentFolder: boolean; // Folder that also has a component
+  canBecomeRoot: boolean;
+  hasWarnings: boolean;
+  children: TreeNode[];
+}
+
+/**
+ * Tree node can be either component or folder
+ */
+export type TreeNode = ComponentItemData | FolderItemData;
+
+/**
+ * Sheet/tab information
+ */
+export interface SheetData {
+  name: string;
+  displayName: string;
+  folder: ComponentsPanelFolder;
+  isDefault: boolean;
+  isSelected: boolean;
+}
+
+/**
+ * Context menu item configuration
+ */
+export interface ContextMenuItem {
+  icon?: string;
+  label: string;
+  onClick: () => void;
+  type?: 'divider';
+}
+```
+
+---
+
+## Step 3: Create Base Component
+
+### 3.1 Create `ComponentsPanel.tsx`
+
+Start with a minimal shell:
+
+```typescript
+/**
+ * ComponentsPanel
+ *
+ * Modern React implementation of the components sidebar panel.
+ * Displays project component hierarchy with folders, allows drag-drop reorganization,
+ * and provides context menus for component/folder operations.
+ */
+
+import React from 'react';
+
+import css from './ComponentsPanel.module.scss';
+import { ComponentsPanelProps } from './types';
+
+export function ComponentsPanel(props: ComponentsPanelProps) {
+  const {
+    nodeGraphEditor,
+    showSheetList = true,
+    hideSheets = [],
+    componentTitle = 'Components',
+    lockCurrentSheetName
+  } = props;
+
+  return (
+    <div className={css.ComponentsPanel}>
+      <div className={css.Header}>
+        <div className={css.Title}>{componentTitle}</div>
+        <button className={css.AddButton} title="Add component">
+          <div className={css.AddIcon}>+</div>
+        </button>
+      </div>
+
+      {showSheetList && (
+        <div className={css.SheetsSection}>
+          <div className={css.SheetsHeader}>Sheets</div>
+          <div className={css.SheetsList}>
+            {/* Sheet tabs will go here */}
+            <div className={css.SheetItem}>Default</div>
+          </div>
+        </div>
+      )}
+
+      <div className={css.ComponentsHeader}>
+        <div className={css.Title}>Components</div>
+      </div>
+
+      <div className={css.ComponentsScroller}>
+        <div className={css.ComponentsList}>
+          {/* Placeholder content */}
+          <div className={css.PlaceholderItem}>📁 Folder 1</div>
+          <div className={css.PlaceholderItem}>📄 Component 1</div>
+          <div className={css.PlaceholderItem}>📄 Component 2</div>
+        </div>
+      </div>
+    </div>
+  );
+}
+```
+
+---
+
+## Step 4: Create Base Styles
+
+### 4.1 Create `ComponentsPanel.module.scss`
+
+Port essential styles from the legacy CSS:
+
+```scss
+/**
+ * ComponentsPanel Styles
+ * Ported from legacy componentspanel.css
+ */
+
+.ComponentsPanel {
+  display: flex;
+  flex-direction: column;
+  height: 100%;
+  background-color: var(--theme-color-bg-1);
+  color: var(--theme-color-fg-default);
+  overflow: hidden;
+}
+
+/* Header sections */
+.Header,
+.SheetsHeader,
+.ComponentsHeader {
+  display: flex;
+  align-items: center;
+  justify-content: space-between;
+  padding: 8px 10px;
+  font: 11px var(--font-family-bold);
+  color: var(--theme-color-fg-default);
+  background-color: var(--theme-color-bg-2);
+  border-bottom: 1px solid var(--theme-color-border-default);
+}
+
+.Title {
+  flex: 1;
+  text-transform: uppercase;
+  letter-spacing: 0.5px;
+}
+
+.AddButton {
+  width: 20px;
+  height: 20px;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  background: transparent;
+  border: none;
+  color: var(--theme-color-fg-default);
+  cursor: pointer;
+  border-radius: 3px;
+  transition: background-color 0.15s ease;
+
+  &:hover {
+    background-color: var(--theme-color-bg-3);
+  }
+}
+
+.AddIcon {
+  font-size: 14px;
+  font-weight: bold;
+}
+
+/* Sheets section */
+.SheetsSection {
+  border-bottom: 1px solid var(--theme-color-border-default);
+}
+
+.SheetsList {
+  max-height: 250px;
+  overflow-y: auto;
+  overflow-x: hidden;
+}
+
+.SheetItem {
+  padding: 8px 10px 8px 30px;
+  font: 11px var(--font-family-regular);
+  cursor: pointer;
+  transition: background-color 0.15s ease;
+
+  &:hover {
+    background-color: var(--theme-color-bg-3);
+  }
+}
+
+/* Components list */

+
+  &:hover {
+    background: var(--theme-color-fg-muted);
+  }
+}
+```
+
+---
+
+## Step 5: Create Export File
+
+### 5.1 Create `index.ts`
+
+```typescript
+export { ComponentsPanel } from './ComponentsPanel';
+export * from './types';
+```
+
+---
+
+## Step 6: Register with SidebarModel
+
+### 6.1 Update `router.setup.ts`
+
+Find the existing ComponentsPanel registration and update it:
+
+**Before:**
+
+```typescript
+const ComponentsPanel = require('./views/panels/componentspanel/ComponentsPanel').ComponentsPanelView;
+```
+
+**After:**
+
+```typescript
+import { ComponentsPanel } from './views/panels/ComponentsPanel';
+```
+
+**Registration (should already exist, just verify):**
+
+```typescript
+SidebarModel.instance.register({
+  id: 'components',
+  name: 'Components',
+  order: 1,
+  icon: IconName.Components,
+  onOpen: (args) => {
+    const panel = new ComponentsPanel({
+      nodeGraphEditor: args.context.nodeGraphEditor,
+      showSheetList: true,
+      hideSheets: ['__cloud__']
+    });
+    panel.render();
+    return panel.el;
+  }
+});
+```
+
+**Update to:**
+
+```typescript
+SidebarModel.instance.register({
+  id: 'components',
+  name: 'Components',
+  order: 1,
+  icon: IconName.Components,
+  panel: ComponentsPanel,
+  panelProps: {
+    nodeGraphEditor: undefined, // Will be set by SidePanel
+    showSheetList: true,
+    hideSheets: ['__cloud__']
+  }
+});
+```
+
+**Note:** Check how `SidebarModel` handles React components. You may need to look at how `SearchPanel.tsx` or other React panels are registered.
+
+---
+
+## Step 7: Testing
+
+### 7.1 Build and Run
+
+```bash
+npm run dev
+```
+
+### 7.2 Verification Checklist
+
+- [ ] No TypeScript compilation errors
+- [ ] Application starts without errors
+- [ ] Clicking "Components" icon in sidebar shows panel
+- [ ] Panel displays with header "Components"
+- [ ] "+" button appears in header
+- [ ] Placeholder items are visible
+- [ ] If `showSheetList` is true, "Sheets" section appears
+- [ ] No console errors or warnings
+- [ ] Styles look consistent with other sidebar panels
+
+### 7.3 Test Edge Cases
+
+- [ ] Panel resizes correctly with window
+- [ ] Scrollbar appears if content overflows
+- [ ] Panel switches correctly with other sidebar panels
+
+---
+
+## Common Issues & Solutions
+
+### Issue: Panel doesn't appear
+
+**Solution:** Check that `SidebarModel` registration is correct. Look at how other React panels like `SearchPanel` are registered.
+
+### Issue: Styles not applying
+
+**Solution:** Verify CSS module import path is correct and webpack is configured to handle `.module.scss` files.
+
+### Issue: TypeScript errors with ComponentModel
+
+**Solution:** Ensure all `@noodl-models` imports are available. Check `tsconfig.json` paths.
+
+### Issue: "nodeGraphEditor" prop undefined
+
+**Solution:** `SidePanel` should inject this. Check that prop passing matches other panels.

+# Phase 2: Tree Rendering
+
+**Estimated Time:** 1-2 hours  
+**Complexity:** Medium  
+**Prerequisites:** Phase 1 complete (foundation set up)
+
+## Overview
+
+Connect the ComponentsPanel to ProjectModel and render the actual component tree structure with folders, proper selection handling, and correct icons. This phase brings the panel to life with real data.
+
+---
+
+## Goals
+
+- ✅ Subscribe to ProjectModel events for component changes
+- ✅ Build folder/component tree structure from ProjectModel
+- ✅ Implement recursive tree rendering
+- ✅ Add expand/collapse for folders
+- ✅ Implement component selection sync with NodeGraphEditor
+- ✅ Show correct icons (home, page, cloud, visual, folder)
+- ✅ Handle component warnings display
+
+---
+
+## Step 1: Create Tree Rendering Components
+
+### 1.1 Create `components/ComponentTree.tsx`
+
+Recursive component for rendering the tree:
+
+```typescript
+/**
+ * ComponentTree
+ *
+ * Recursively renders the component/folder tree structure.
+ */
+
+import React from 'react';
+
+import { TreeNode } from '../types';
+import { ComponentItem } from './ComponentItem';
+import { FolderItem } from './FolderItem';
+
+interface ComponentTreeProps {
+  nodes: TreeNode[];
+  level?: number;
+  onItemClick: (node: TreeNode) => void;
+  onCaretClick: (folderId: string) => void;
+  expandedFolders: Set<string>;
+  selectedId?: string;
+}
+
+export function ComponentTree({
+  nodes,
+  level = 0,
+  onItemClick,
+  onCaretClick,
+  expandedFolders,
+  selectedId
+}: ComponentTreeProps) {
+  return (
+    <>
+      {nodes.map((node) => {
+        if (node.type === 'folder') {
+          return (
+            <FolderItem
+              key={node.path}
+              folder={node}
+              level={level}
+              isExpanded={expandedFolders.has(node.path)}
+              isSelected={selectedId === node.path}
+              onCaretClick={() => onCaretClick(node.path)}
+              onClick={() => onItemClick(node)}
+            >
+              {expandedFolders.has(node.path) && node.children.length > 0 && (
+                <ComponentTree
+                  nodes={node.children}
+                  level={level + 1}
+                  onItemClick={onItemClick}
+                  onCaretClick={onCaretClick}
+                  expandedFolders={expandedFolders}
+                  selectedId={selectedId}
+                />
+              )}
+            </FolderItem>
+          );
+        } else {
+          return (
+            <ComponentItem
+              key={node.fullName}
+              component={node}
+              level={level}
+              isSelected={selectedId === node.fullName}
+              onClick={() => onItemClick(node)}
+            />
+          );
+        }
+      })}
+    </>
+  );
+}
+```
+
+### 1.2 Create `components/FolderItem.tsx`
+
+Component for rendering folder rows:
+
+```typescript
+/**
+ * FolderItem
+ *
+ * Renders a folder row with expand/collapse caret and nesting.
+ */
+
+import classNames from 'classnames';
+import React from 'react';
+
+import { IconName } from '@noodl-core-ui/components/common/Icon';
+
+import css from '../ComponentsPanel.module.scss';
+import { FolderItemData } from '../types';
+
+interface FolderItemProps {
+  folder: FolderItemData;
+  level: number;
+  isExpanded: boolean;
+  isSelected: boolean;
+  onCaretClick: () => void;
+  onClick: () => void;
+  children?: React.ReactNode;
+}
+
+export function FolderItem({
+  folder,
+  level,
+  isExpanded,
+  isSelected,
+  onCaretClick,
+  onClick,
+  children
+}: FolderItemProps) {
+  const indent = level * 12;
+
+  return (
+    <>
+      <div
+        className={classNames(css.TreeItem, {
+          [css.Selected]: isSelected
+        })}
+        style={{ paddingLeft: `${indent + 10}px` }}
+      >
+        <div
+          className={classNames(css.Caret, {
+            [css.Expanded]: isExpanded
+          })}
+          onClick={(e) => {
+            e.stopPropagation();
+            onCaretClick();
+          }}
+        >
+          ▶
+        </div>
+        <div className={css.ItemContent} onClick={onClick}>
+          <div className={css.Icon}>{folder.isComponentFolder ? IconName.FolderComponent : IconName.Folder}</div>
+          <div className={css.Label}>{folder.name}</div>
+          {folder.hasWarnings && <div className={css.Warning}>!</div>}
+        </div>
+      </div>
+      {children}
+    </>
+  );
+}
+```
+
+### 1.3 Create `components/ComponentItem.tsx`
+
+Component for rendering component rows:
+
+```typescript
+/**
+ * ComponentItem
+ *
+ * Renders a single component row with appropriate icon.
+ */
+
+import classNames from 'classnames';
+import React from 'react';
+
+import { IconName } from '@noodl-core-ui/components/common/Icon';
+
+import css from '../ComponentsPanel.module.scss';
+import { ComponentItemData } from '../types';
+
+interface ComponentItemProps {
+  component: ComponentItemData;
+  level: number;
+  isSelected: boolean;
+  onClick: () => void;
+}
+
+export function ComponentItem({ component, level, isSelected, onClick }: ComponentItemProps) {
+  const indent = level * 12;
+
+  // Determine icon based on component type
+  let icon = IconName.Component;
+  if (component.isRoot) {
+    icon = IconName.Home;
+  } else if (component.isPage) {
+    icon = IconName.Page;
+  } else if (component.isCloudFunction) {
+    icon = IconName.Cloud;
+  } else if (component.isVisual) {
+    icon = IconName.Visual;
+  }
+
+  return (
+    <div
+      className={classNames(css.TreeItem, {
+        [css.Selected]: isSelected
+      })}
+      style={{ paddingLeft: `${indent + 23}px` }}
+      onClick={onClick}
+    >
+      <div className={css.ItemContent}>
+        <div className={css.Icon}>{icon}</div>
+        <div className={css.Label}>{component.name}</div>
+        {component.hasWarnings && <div className={css.Warning}>!</div>}
+      </div>
+    </div>
+  );
+}
+```
+
+---
+
+## Step 2: Create State Management Hook
+
+### 2.1 Create `hooks/useComponentsPanel.ts`
+
+Main hook for managing panel state:
+
+```typescript
+/**
+ * useComponentsPanel
+ *
+ * Main state management hook for ComponentsPanel.
+ * Subscribes to ProjectModel and builds tree structure.
+ */
+
+import { useCallback, useEffect, useMemo, useState } from 'react';
+
+import { ProjectModel } from '@noodl-models/projectmodel';
+
+import { ComponentsPanelFolder } from '../../componentspanel/ComponentsPanelFolder';
+import { ComponentItemData, FolderItemData, TreeNode } from '../types';
+
+interface UseComponentsPanelOptions {
+  hideSheets?: string[];
+  lockCurrentSheetName?: string;
+}
+
+export function useComponentsPanel(options: UseComponentsPanelOptions = {}) {
+  const { hideSheets = [], lockCurrentSheetName } = options;
+
+  // Local state
+  const [expandedFolders, setExpandedFolders] = useState<Set<string>>(new Set(['/']));
+  const [selectedId, setSelectedId] = useState<string | undefined>();
+  const [updateCounter, setUpdateCounter] = useState(0);
+
+  // Subscribe to ProjectModel events
+  useEffect(() => {
+    const handleUpdate = () => {
+      setUpdateCounter((c) => c + 1);
+    };
+
+    ProjectModel.instance.on('componentAdded', handleUpdate);
+    ProjectModel.instance.on('componentRemoved', handleUpdate);
+    ProjectModel.instance.on('componentRenamed', handleUpdate);
+    ProjectModel.instance.on('rootComponentChanged', handleUpdate);
+
+    return () => {
+      ProjectModel.instance.off('componentAdded', handleUpdate);
+      ProjectModel.instance.off('componentRemoved', handleUpdate);
+      ProjectModel.instance.off('componentRenamed', handleUpdate);
+      ProjectModel.instance.off('rootComponentChanged', handleUpdate);
+    };
+  }, []);
+
+  // Build tree structure
+  const treeData = useMemo(() => {
+    return buildTreeFromProject(ProjectModel.instance, hideSheets, lockCurrentSheetName);
+  }, [updateCounter, hideSheets, lockCurrentSheetName]);
+
+  // Toggle folder expand/collapse
+  const toggleFolder = useCallback((folderId: string) => {
+    setExpandedFolders((prev) => {
+      const next = new Set(prev);
+      if (next.has(folderId)) {
+        next.delete(folderId);
+      } else {
+        next.add(folderId);
+      }
+      return next;
+    });
+  }, []);
+
+  // Handle item click
+  const handleItemClick = useCallback((node: TreeNode) => {
+    if (node.type === 'component') {
+      setSelectedId(node.fullName);
+      // TODO: Open component in NodeGraphEditor
+    } else {
+      setSelectedId(node.path);
+    }
+  }, []);
+
+  return {
+    treeData,
+    expandedFolders,
+    selectedId,
+    toggleFolder,
+    handleItemClick
+  };
+}
+
+/**
+ * Build tree structure from ProjectModel
+ * Port logic from ComponentsPanel.ts addComponentToFolderStructure
+ */
+function buildTreeFromProject(project: ProjectModel, hideSheets: string[], lockSheet?: string): TreeNode[] {
+  // TODO: Implement tree building logic
+  // This will port the logic from legacy ComponentsPanel.ts
+  // For now, return placeholder structure
+  return [];
+}
+```
+
+---
+
+## Step 3: Add Styles for Tree Items
+
+### 3.1 Update `ComponentsPanel.module.scss`
+
+Add styles for tree items:
+
+```scss
+/* Tree items */
+.TreeItem {
+  display: flex;
+  align-items: center;
+  padding: 6px 10px;
+  cursor: pointer;
+  font: 11px var(--font-family-regular);
+  color: var(--theme-color-fg-default);
+  user-select: none;
+  transition: background-color 0.15s ease;
+
+  &:hover {
+    background-color: var(--theme-color-bg-3);
+  }
+
+  &.Selected {
+    background-color: var(--theme-color-primary-transparent);
+    color: var(--theme-color-primary);
+  }
+}
+
+.Caret {
+  width: 12px;
+  height: 12px;
+  margin-right: 4px;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  font-size: 8px;
+  color: var(--theme-color-fg-muted);
+  transition: transform 0.15s ease;
+
+  &.Expanded {
+    transform: rotate(90deg);
+  }
+}
+
+.ItemContent {
+  display: flex;
+  align-items: center;
+  flex: 1;
+  gap: 6px;
+}
+
+.Icon {
+  width: 16px;
+  height: 16px;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  color: var(--theme-color-fg-default);
+}
+
+.Label {
+  flex: 1;
+  overflow: hidden;
+  text-overflow: ellipsis;
+  white-space: nowrap;
+}
+
+.Warning {
+  width: 16px;
+  height: 16px;
+  display: flex;
+  align-items: center;
+  justify-content: center;
+  background-color: var(--theme-color-warning);
+  color: var(--theme-color-bg-1);
+  border-radius: 50%;
+  font-size: 10px;
+  font-weight: bold;
+}
+```
+
+---
+
+## Step 4: Integrate Tree Rendering
+
+### 4.1 Update `ComponentsPanel.tsx`
+
+Replace placeholder content with actual tree:
+
+```typescript
+import React from 'react';
+
+import { ComponentTree } from './components/ComponentTree';
+import css from './ComponentsPanel.module.scss';
+import { useComponentsPanel } from './hooks/useComponentsPanel';
+import { ComponentsPanelProps } from './types';
+
+export function ComponentsPanel(props: ComponentsPanelProps) {
+  const {
+    nodeGraphEditor,
+    showSheetList = true,
+    hideSheets = [],
+    componentTitle = 'Components',
+    lockCurrentSheetName
+  } = props;
+
+  const { treeData, expandedFolders, selectedId, toggleFolder, handleItemClick } = useComponentsPanel({
+    hideSheets,
+    lockCurrentSheetName
+  });
+
+  return (
+    <div className={css.ComponentsPanel}>
+      <div className={css.Header}>
+        <div className={css.Title}>{componentTitle}</div>
+        <button className={css.AddButton} title="Add component">
+          <div className={css.AddIcon}>+</div>
+        </button>
+      </div>
+
+      {showSheetList && (
+        <div className={css.SheetsSection}>
+          <div className={css.SheetsHeader}>Sheets</div>
+          <div className={css.SheetsList}>{/* TODO: Implement sheet selector in Phase 6 */}</div>
+        </div>
+      )}
+
+      <div className={css.ComponentsHeader}>
+        <div className={css.Title}>Components</div>
+      </div>
+
+      <div className={css.ComponentsScroller}>
+        <div className={css.ComponentsList}>
+          <ComponentTree
+            nodes={treeData}
+            expandedFolders={expandedFolders}
+            selectedId={selectedId}
+            onItemClick={handleItemClick}
+            onCaretClick={toggleFolder}
+          />
+        </div>
+      </div>
+    </div>
+  );
+}
+```
+
+---
+
+## Step 5: Port Tree Building Logic
+
+### 5.1 Implement `buildTreeFromProject`
+
+Port logic from legacy `ComponentsPanel.ts`:
+
+```typescript
+function buildTreeFromProject(project: ProjectModel, hideSheets: string[], lockSheet?: string): TreeNode[] {
+  const rootFolder = new ComponentsPanelFolder({ path: '/', name: '' });
+
+  // Get all components
+  const components = project.getComponents();
+
+  // Filter by sheet if specified
+  const filteredComponents = components.filter((comp) => {
+    const sheet = getSheetForComponent(comp.name);
+    if (hideSheets.includes(sheet)) return false;
+    if (lockSheet && sheet !== lockSheet) return false;
+    return true;
+  });
+
+  // Add each component to folder structure
+  filteredComponents.forEach((comp) => {
+    addComponentToFolderStructure(rootFolder, comp, project);
+  });
+
+  // Convert folder structure to tree nodes
+  return convertFolderToTreeNodes(rootFolder);
+}
+
+function addComponentToFolderStructure(
+  rootFolder: ComponentsPanelFolder,
+  component: ComponentModel,
+  project: ProjectModel
+) {
+  const parts = component.name.split('/');
+  let currentFolder = rootFolder;
+
+  // Navigate/create folder structure
+  for (let i = 0; i < parts.length - 1; i++) {
+    const folderName = parts[i];
+    let folder = currentFolder.children.find((c) => c.name === folderName);
+
+    if (!folder) {
+      folder = new ComponentsPanelFolder({
+        path: parts.slice(0, i + 1).join('/'),
+        name: folderName
+      });
+      currentFolder.children.push(folder);
+    }
+
+    currentFolder = folder;
+  }
+
+  // Add component to final folder
+  currentFolder.components.push(component);
+}
+
+function convertFolderToTreeNodes(folder: ComponentsPanelFolder): TreeNode[] {
+  const nodes: TreeNode[] = [];
+
+  // Add folder children first
+  folder.children.forEach((childFolder) => {
+    const folderNode: FolderItemData = {
+      type: 'folder',
+      folder: childFolder,
+      name: childFolder.name,
+      path: childFolder.path,
+      isOpen: false,
+      isSelected: false,
+      isRoot: childFolder.path === '/',
+      isPage: false,
+      isCloudFunction: false,
+      isVisual: true,
+      isComponentFolder: childFolder.components.length > 0,
+      canBecomeRoot: false,
+      hasWarnings: false,
+      children: convertFolderToTreeNodes(childFolder)
+    };
+    nodes.push(folderNode);
+  });
+
+  // Add components
+  folder.components.forEach((comp) => {
+    const componentNode: ComponentItemData = {
+      type: 'component',
+      component: comp,
+      folder: folder,
+      name: comp.name.split('/').pop() || comp.name,
+      fullName: comp.name,
+      isSelected: false,
+      isRoot: ProjectModel.instance.getRootComponent() === comp,
+      isPage: comp.type === 'Page',
+      isCloudFunction: comp.type === 'CloudFunction',

+## Step 6: Testing
+
+### 6.1 Verification Checklist
+
+- [ ] Tree renders with correct folder structure
+- [ ] Components appear under correct folders
+- [ ] Clicking caret expands/collapses folders
+- [ ] Clicking component selects it
+- [ ] Home icon appears for root component
+- [ ] Page icon appears for page components
+- [ ] Cloud icon appears for cloud functions
+- [ ] Visual icon appears for visual components
+- [ ] Folder icons appear correctly
+- [ ] Folder+component icon for folders that are also components
+- [ ] Warning icons appear (when implemented)
+- [ ] No console errors
+
+### 6.2 Test Edge Cases
+
+- [ ] Empty project (no components)
+- [ ] Deep folder nesting
+- [ ] Component names with special characters
+- [ ] Sheet filtering works correctly
+- [ ] Hidden sheets are excluded
+
+---
+
+## Common Issues & Solutions
+
+### Issue: Tree doesn't update when components change
+
+**Solution:** Verify ProjectModel event subscriptions are correct and updateCounter increments.
+
+### Issue: Folders don't expand
+
+**Solution:** Check that `expandedFolders` Set is being updated correctly and ComponentTree receives updated props.
+
+### Issue: Icons not showing
+
+**Solution:** Verify Icon component import and that IconName values are correct.
+
+### Issue: Selection doesn't work
+
+**Solution:** Check that `selectedId` is being set correctly and CSS `.Selected` class is applied.
+
+---
+
+## Success Criteria
+
+✅ **Phase 2 is complete when:**
+
+1. Component tree renders with actual project data
+2. Folders expand and collapse correctly
+3. Components can be selected
+4. All icons display correctly
+5. Selection highlights correctly
+6. Tree updates when project changes
+7. No console errors or warnings
+
+---
+
+## Next Phase
+
+**Phase 3: Context Menus** - Add context menu functionality for components and folders.

+# Phase 3: Context Menus
+
+**Estimated Time:** 1 hour  
+**Complexity:** Low  
+**Prerequisites:** Phase 2 complete (tree rendering working)
+
+## Overview
+
+Add context menu functionality for components and folders, including add component menu, rename, duplicate, delete, and make home actions. All actions should integrate with UndoQueue for proper undo/redo support.
+
+---
+
+## Goals
+
+- ✅ Implement header "+" button menu
+- ✅ Implement component right-click context menu
+- ✅ Implement folder right-click context menu
+- ✅ Wire up add component action
+- ✅ Wire up rename action
+- ✅ Wire up duplicate action
+- ✅ Wire up delete action
+- ✅ Wire up make home action
+- ✅ All actions use UndoQueue

+
+## Step 1: Create Add Component Menu
+
+### 1.1 Create `components/AddComponentMenu.tsx`
+
+Menu for adding new components/folders:
+
+```typescript
+/**
+ * AddComponentMenu
+ *
+ * Dropdown menu for adding new components or folders.
+ * Integrates with ComponentTemplates system.
+ */
+
+import PopupLayer from '@noodl-views/popuplayer';
+import React, { useCallback } from 'react';
+
+import { IconName } from '@noodl-core-ui/components/common/Icon';
+
+import { ComponentTemplates } from '../../componentspanel/ComponentTemplates';
+
+interface AddComponentMenuProps {
+  targetElement: HTMLElement;
+  onClose: () => void;
+  parentPath?: string;
+}
+
+export function AddComponentMenu({ targetElement, onClose, parentPath = '' }: AddComponentMenuProps) {
+  const handleAddComponent = useCallback(
+    (templateId: string) => {
+      const template = ComponentTemplates.instance.getTemplate(templateId);
+      if (!template) return;
+
+      // TODO: Create component with template
+      // This will integrate with ProjectModel
+      console.log('Add component:', templateId, 'at path:', parentPath);
+
+      onClose();
+    },
+    [parentPath, onClose]
+  );
+
+  const handleAddFolder = useCallback(() => {
+    // TODO: Create new folder
+    console.log('Add folder at path:', parentPath);
+    onClose();
+  }, [parentPath, onClose]);
+
+  // Build menu items from templates
+  const templates = ComponentTemplates.instance.getTemplates();
+  const menuItems = templates.map((template) => ({
+    icon: template.icon || IconName.Component,
+    label: template.displayName || template.name,
+    onClick: () => handleAddComponent(template.id)
+  }));
+
+  // Add folder option
+  menuItems.push(
+    { type: 'divider' as const },
+    {
+      icon: IconName.Folder,
+      label: 'Folder',
+      onClick: handleAddFolder
+    }
+  );
+
+  // Show popup menu
+  const menu = new PopupLayer.PopupMenu({ items: menuItems });
+
+  PopupLayer.instance.showPopup({
+    content: menu,
+    attachTo: targetElement,
+    position: 'bottom'
+  });
+
+  return null;
+}
+```
+
+---
+
+## Step 2: Add Context Menu Handlers
+
+### 2.1 Update `ComponentItem.tsx`
+
+Add right-click handler:
+
+```typescript
+export function ComponentItem({ component, level, isSelected, onClick }: ComponentItemProps) {
+  const indent = level * 12;
+
+  const handleContextMenu = useCallback(

+      style={{ paddingLeft: `${indent + 23}px` }}
+      onClick={onClick}
+      onContextMenu={handleContextMenu}

+      onClick: () => {
+        // TODO: Delete component
+      }
+    }
+  ];
+}
+```
+
+### 2.2 Update `FolderItem.tsx`
+
+Add right-click handler:
+
+```typescript
+export function FolderItem({
+  folder,
+  level,
+  isExpanded,
+  isSelected,
+  onCaretClick,
+  onClick,
+  children

+        onContextMenu={handleContextMenu}
+      >
+        {/* ... existing content ... */}
+      </div>
+      {children}
+    </>
+  );
+}
+
+function buildFolderContextMenu(folder: FolderItemData) {
+  return [
+    {
+      icon: IconName.Plus,

+        // TODO: Delete folder and contents
+      }
+    }
+  ];
+}
+```
+
+---
+
+## Step 3: Implement Action Handlers
+
+### 3.1 Create `hooks/useComponentActions.ts`
+
+Hook for handling component actions:
+
+```typescript
+/**
+ * useComponentActions
+ *
+ * Provides handlers for component/folder actions.
+ * Integrates with UndoQueue for all operations.
+ */
+
+import { ToastLayer } from '@noodl-views/ToastLayer/ToastLayer';

+import { ProjectModel } from '@noodl-models/projectmodel';
+import { UndoQueue, UndoActionGroup } from '@noodl-models/undo-queue-model';
+
+import { ComponentItemData, FolderItemData } from '../types';
+
+export function useComponentActions() {
+  const handleMakeHome = useCallback((item: ComponentItemData | FolderItemData) => {
+    const componentName = item.type === 'component' ? item.fullName : item.path;
+    const component = ProjectModel.instance.getComponentWithName(componentName);
+
+    if (!component) {
+      ToastLayer.showError('Component not found');
+      return;
+    }
+
+    const previousRoot = ProjectModel.instance.getRootComponent();
+
+    UndoQueue.instance.pushAndDo(
+      new UndoActionGroup({
+        label: `Make ${component.name} home`,
+        do: () => {

+          }
+        }
+      })
+    );
+  }, []);
+
+  const handleDelete = useCallback((item: ComponentItemData | FolderItemData) => {
+    const itemName = item.type === 'component' ? item.name : item.name;
+
+    // Confirm deletion

+    }
+  }, []);
+
+  const handleDuplicate = useCallback((item: ComponentItemData | FolderItemData) => {
+    if (item.type === 'component') {
+      const component = item.component;
+      const newName = ProjectModel.instance.findUniqueComponentName(component.name + ' Copy');
+
+      UndoQueue.instance.pushAndDo(

+  }, []);
+
+  return {
+    handleMakeHome,
+    handleDelete,
+    handleDuplicate,
+    handleRename
+  };
+}
+```
+
+---
+
+## Step 4: Wire Up Actions
+
+### 4.1 Update `ComponentsPanel.tsx`
+
+Integrate action handlers:
+
+```typescript
+import React, { useCallback, useState } from 'react';
+
+import { ComponentTree } from './components/ComponentTree';
+import css from './ComponentsPanel.module.scss';
+import { useComponentActions } from './hooks/useComponentActions';
+import { useComponentsPanel } from './hooks/useComponentsPanel';
+import { ComponentsPanelProps } from './types';
+
+export function ComponentsPanel(props: ComponentsPanelProps) {
+  const { showSheetList = true, hideSheets = [], componentTitle = 'Components', lockCurrentSheetName } = props;
+
+  const { treeData, expandedFolders, selectedId, toggleFolder, handleItemClick } = useComponentsPanel({
+    hideSheets,
+    lockCurrentSheetName
+  });
+
+  const { handleMakeHome, handleDelete, handleDuplicate, handleRename } = useComponentActions();
+
+  const [addButtonRef, setAddButtonRef] = useState<HTMLButtonElement | null>(null);
+  const [showAddMenu, setShowAddMenu] = useState(false);
+
+  const handleAddButtonClick = useCallback(() => {
+    setShowAddMenu(true);
+  }, []);
+
+  return (
+    <div className={css.ComponentsPanel}>
+      <div className={css.Header}>
+        <div className={css.Title}>{componentTitle}</div>
+        <button ref={setAddButtonRef} className={css.AddButton} title="Add component" onClick={handleAddButtonClick}>
+          <div className={css.AddIcon}>+</div>
+        </button>
+      </div>
+
+      {/* ... rest of component ... */}
+
+      {showAddMenu && addButtonRef && (
+        <AddComponentMenu targetElement={addButtonRef} onClose={() => setShowAddMenu(false)} parentPath="" />
+      )}
+    </div>
+  );
+}
+```
+
+---
+
+## Step 5: Testing
+
+### 5.1 Verification Checklist
+
+- [ ] Header "+" button shows add menu
+- [ ] Add menu includes all component templates
+- [ ] Add menu includes "Folder" option
+- [ ] Right-click on component shows context menu
+- [ ] Right-click on folder shows context menu
+- [ ] "Make Home" action works (and is disabled appropriately)
+- [ ] "Rename" action triggers (implementation in Phase 5)
+- [ ] "Duplicate" action works
+- [ ] "Delete" action works with confirmation
+- [ ] All actions can be undone
+- [ ] All actions can be redone
+- [ ] No console errors
+
+### 5.2 Test Edge Cases
+
+- [ ] Try to make home on component that can't be home
+- [ ] Try to delete root component (should prevent or handle)
+- [ ] Duplicate component with same name (should auto-rename)
+- [ ] Delete last component in folder
+- [ ] Context menu closes when clicking outside
+
+---
+
+## Common Issues & Solutions
+
+### Issue: Context menu doesn't appear
+
+**Solution:** Check that `onContextMenu` handler is attached and `e.preventDefault()` is called.
+
+### Issue: Menu appears in wrong position
+
+**Solution:** Verify PopupLayer position parameters. Use `{ x: e.clientX, y: e.clientY }` for mouse position.
+
+### Issue: Actions don't work
+
+**Solution:** Check that ProjectModel methods are being called correctly and UndoQueue integration is proper.
+
+### Issue: Undo doesn't work
+
+**Solution:** Verify that UndoActionGroup is created correctly with both `do` and `undo` functions.
+
+---
+
+## Success Criteria
+
+✅ **Phase 3 is complete when:**
+
+1. Header "+" button shows add menu
+2. All context menus work correctly
+3. Make home action works
+4. Delete action works with confirmation
+5. Duplicate action works
+6. All actions integrate with UndoQueue
+7. Undo/redo works for all actions
+8. No console errors

+**Estimated Time:** 2 hours  
+**Complexity:** High  
+**Prerequisites:** Phase 3 complete (context menus working)
+
+## Overview
+
+Implement drag-drop functionality for reorganizing components and folders. Users should be able to drag components into folders, drag folders into other folders, and reorder items. The system should integrate with existing PopupLayer drag system and UndoQueue.
+
+---
+
+## Goals
+
+- ✅ Implement drag initiation on mouse down + move
+- ✅ Show drag ghost with item name
+- ✅ Implement drop zones on folders and components
+- ✅ Validate drop targets (prevent invalid drops)
+- ✅ Execute drop operations
+- ✅ Create undo actions for all drops
+- ✅ Handle cross-sheet drops
+- ✅ Show visual feedback for valid/invalid drops
+
+---
+
+## Step 1: Create Drag-Drop Hook

+
+  // Start dragging
+  const startDrag = useCallback((item: TreeNode, sourceElement: HTMLElement) => {

+}
+```
+
+---
+
+## Step 2: Add Drag Handlers to Components
+
+### 2.1 Update `ComponentItem.tsx`
+
+Add drag initiation:
+
+```typescript
+import { useRef } from 'react';
+
+export function ComponentItem({ component, level, isSelected, onClick, onDragStart }: ComponentItemProps) {
+  const itemRef = useRef<HTMLDivElement>(null);

+
+  const handleMouseDown = useCallback((e: React.MouseEvent) => {
+    // Track mouse down position
+    dragStartPos.current = { x: e.clientX, y: e.clientY };
+  }, []);
+
+  const handleMouseMove = useCallback(
+    (e: React.MouseEvent) => {
+      if (!dragStartPos.current) return;
+
+      // Check if mouse moved enough to start drag
+      const dx = e.clientX - dragStartPos.current.x;
+      const dy = e.clientY - dragStartPos.current.y;
+      const distance = Math.sqrt(dx * dx + dy * dy);
+
+      if (distance > 5 && itemRef.current) {
+        onDragStart?.(component, itemRef.current);
+        dragStartPos.current = null;
+      }

+      </div>
+    </div>
+  );
+}
+```
+
+### 2.2 Update `FolderItem.tsx`
+
+Add drag initiation and drop zone:
+
+```typescript
+export function FolderItem({
+  folder,
+  level,
+  isExpanded,
+  isSelected,
+  onCaretClick,

+      </div>
+      {children}
+    </>
+  );
+}
+```
+
+---
+
+## Step 3: Implement Drop Execution
+
+### 3.1 Create Drop Handler in `useComponentActions.ts`
+
+Add drop execution logic:
+
+```typescript
+export function useComponentActions() {
+  // ... existing handlers ...
+
+  const handleDropOn = useCallback((draggedItem: TreeNode, targetItem: TreeNode) => {
+    if (draggedItem.type === 'component' && targetItem.type === 'folder') {
+      // Move component to folder
+      const component = draggedItem.component;
+      const targetPath = targetItem.path === '/' ? '' : targetItem.path;
+      const newName = targetPath ? `${targetPath}/${draggedItem.name}` : draggedItem.name;
+
+      // Check for naming conflicts
+      if (ProjectModel.instance.getComponentWithName(newName)) {
+        ToastLayer.showError(`Component "${newName}" already exists`);
+        return;
+      }
+
+      const oldName = component.name;
+
+      UndoQueue.instance.pushAndDo(
+        new UndoActionGroup({
+          label: `Move ${component.name} to ${targetItem.name}`,
+          do: () => {
+            ProjectModel.instance.renameComponent(component, newName);
+          },
+          undo: () => {
+            ProjectModel.instance.renameComponent(component, oldName);
+          }
+        })
+      );
+    } else if (draggedItem.type === 'folder' && targetItem.type === 'folder') {
+      // Move folder to folder
+      const sourcePath = draggedItem.path;
+      const targetPath = targetItem.path === '/' ? '' : targetItem.path;
+      const newPath = targetPath ? `${targetPath}/${draggedItem.name}` : draggedItem.name;
+
+      // Get all components in source folder
+      const componentsToMove = getComponentsInFolder(sourcePath);
+
+      if (componentsToMove.length === 0) {
+        ToastLayer.showInfo('Folder is empty');
+        return;
+      }
+
+      const renames: Array<{ component: ComponentModel; oldName: string; newName: string }> = [];
+
+      componentsToMove.forEach((comp) => {
+        const relativePath = comp.name.substring(sourcePath.length + 1);
+        const newName = `${newPath}/${relativePath}`;
+        renames.push({ component: comp, oldName: comp.name, newName });
+      });
+
+      UndoQueue.instance.pushAndDo(
+        new UndoActionGroup({
+          label: `Move ${draggedItem.name} to ${targetItem.name}`,
+          do: () => {
+            renames.forEach(({ component, newName }) => {
+              ProjectModel.instance.renameComponent(component, newName);
+            });
+          },
+          undo: () => {
+            renames.forEach(({ component, oldName }) => {
+              ProjectModel.instance.renameComponent(component, oldName);
+            });
+          }
+        })
+      );
+    }
+  }, []);
+
+  return {
+    handleMakeHome,
+    handleDelete,
+    handleDuplicate,
+    handleRename,
+    handleDropOn
+  };
+}
+
+function getComponentsInFolder(folderPath: string): ComponentModel[] {
+  const components = ProjectModel.instance.getComponents();
+  return components.filter((comp) => {
+    return comp.name.startsWith(folderPath + '/');
+  });
+}
+```
+
+---
+
+## Step 4: Add Drop Zone Styles
+
+### 4.1 Update `ComponentsPanel.module.scss`
+
+Add drop target styling:
+
+```scss
+.TreeItem {
+  display: flex;
+  align-items: center;
+  padding: 6px 10px;
+  cursor: pointer;
+  font: 11px var(--font-family-regular);
+  color: var(--theme-color-fg-default);
+  user-select: none;
+  transition: background-color 0.15s ease;
+
+  &:hover {
+    background-color: var(--theme-color-bg-3);
+  }
+
+  &.Selected {
+    background-color: var(--theme-color-primary-transparent);
+    color: var(--theme-color-primary);
+  }
+
+  &.DropTarget {
+    background-color: var(--theme-color-primary-transparent);
+    border: 2px dashed var(--theme-color-primary);
+    border-radius: 4px;
+  }
+
+  &.DragOver {
+    background-color: var(--theme-color-primary-transparent);
+  }
+}
+```
+
+---
+
+## Step 5: Integrate with ComponentsPanel
+
+### 5.1 Update `ComponentsPanel.tsx`
+
+Wire up drag-drop:
+
+```typescript
+export function ComponentsPanel(props: ComponentsPanelProps) {
+  const { showSheetList = true, hideSheets = [], componentTitle = 'Components', lockCurrentSheetName } = props;
+
+  const { treeData, expandedFolders, selectedId, toggleFolder, handleItemClick } = useComponentsPanel({
+    hideSheets,
+    lockCurrentSheetName
+  });
+
+  const { handleMakeHome, handleDelete, handleDuplicate, handleRename, handleDropOn } = useComponentActions();
+
+  const { draggedItem, startDrag, canDrop, handleDrop, clearDrop } = useDragDrop();
+
+  // Handle drop completion
+  useEffect(() => {
+    if (draggedItem && dropTarget) {
+      handleDropOn(draggedItem, dropTarget);
+      clearDrop();
+    }
+  }, [draggedItem, dropTarget, handleDropOn, clearDrop]);
+
+  return (
+    <div className={css.ComponentsPanel}>
+      {/* ... header ... */}
+
+      <div className={css.ComponentsScroller}>
+        <div className={css.ComponentsList}>
+          <ComponentTree
+            nodes={treeData}
+            expandedFolders={expandedFolders}
+            selectedId={selectedId}
+            onItemClick={handleItemClick}
+            onCaretClick={toggleFolder}
+            onDragStart={startDrag}
+            onDrop={handleDrop}
+            canAcceptDrop={canDrop}
+          />
+        </div>
+      </div>
+    </div>
+  );
+}
+```
+
+---
+
+## Step 6: Testing
+
+### 6.1 Verification Checklist
+
+- [ ] Can drag component to folder
+- [ ] Can drag folder to folder
+- [ ] Cannot drag folder into its own children
+- [ ] Cannot drag item onto itself
+- [ ] Drop target highlights correctly
+- [ ] Invalid drops show no feedback
+- [ ] Drop executes correctly
+- [ ] Component moves to new location
+- [ ] Folder with all contents moves
+- [ ] Undo reverses drop
+- [ ] Redo re-applies drop
+- [ ] No console errors
+
+### 6.2 Test Edge Cases
+
+- [ ] Drag to root level (no folder)
+- [ ] Drag component with same name (should error)
+- [ ] Drag empty folder
+- [ ] Drag folder with deeply nested components
+- [ ] Cancel drag (mouse up without drop)
+- [ ] Drag across sheets
+
+---
+
+## Common Issues & Solutions
+
+### Issue: Drag doesn't start
+
+**Solution:** Check that mouse down + move distance calculation is correct. Ensure PopupLayer.startDragging is called.
+
+### Issue: Drop doesn't work
+
+**Solution:** Verify that drop zone event handlers are attached. Check canDrop logic.
+
+### Issue: Folder moves but children don't
+
+**Solution:** Ensure getComponentsInFolder finds all nested components and renames them correctly.
+
+### Issue: Undo breaks after drop
+
+**Solution:** Verify that undo action captures all renamed components and restores original names.
+
+---
+
+## Success Criteria
+
+✅ **Phase 4 is complete when:**
+
+1. Components can be dragged to folders
+2. Folders can be dragged to folders
+3. Invalid drops are prevented
+4. Drop target shows visual feedback
+5. Drops execute correctly
+6. All drops can be undone
+7. No console errors
+
+---
+
+## Next Phase
+
+**Phase 5: Inline Rename** - Implement rename-in-place with validation.

+# Phase 5: Inline Rename
+
+**Estimated Time:** 1 hour  
+**Complexity:** Medium  
+**Prerequisites:** Phase 4 complete (drag-drop working)
+
+## Overview
+
+Implement inline rename functionality allowing users to double-click or use context menu to rename components and folders directly in the tree. Includes validation for duplicate names and proper undo support.
+
+---
+
+## Goals
+
+- ✅ Implement rename mode state management
+- ✅ Show inline input field on rename trigger
+- ✅ Handle Enter to confirm, Escape to cancel
+- ✅ Validate name uniqueness
+- ✅ Handle focus management
+- ✅ Integrate with UndoQueue
+- ✅ Support both component and folder rename
+
+---
+
+## Step 1: Create Rename Hook
+
+### 1.1 Create `hooks/useRenameMode.ts`
+
+```typescript
+/**
+ * useRenameMode
+ *
+ * Manages inline rename state and validation.
+ */
+
+import { ToastLayer } from '@noodl-views/ToastLayer/ToastLayer';
+import { useCallback, useState } from 'react';
+
+import { ProjectModel } from '@noodl-models/projectmodel';
+
+import { TreeNode } from '../types';
+
+export function useRenameMode() {
+  const [renamingItem, setRenamingItem] = useState<TreeNode | null>(null);
+  const [renameValue, setRenameValue] = useState('');
+
+  const startRename = useCallback((item: TreeNode) => {
+    setRenamingItem(item);
+    setRenameValue(item.name);
+  }, []);
+
+  const cancelRename = useCallback(() => {
+    setRenamingItem(null);
+    setRenameValue('');
+  }, []);
+
+  const validateName = useCallback(
+    (newName: string): { valid: boolean; error?: string } => {
+      if (!newName || newName.trim() === '') {
+        return { valid: false, error: 'Name cannot be empty' };
+      }
+
+      if (newName === renamingItem?.name) {
+        return { valid: true }; // No change
+      }
+
+      // Check for invalid characters
+      if (/[<>:"|?*\\]/.test(newName)) {
+        return { valid: false, error: 'Name contains invalid characters' };
+      }
+
+      // Check for duplicate name
+      if (renamingItem?.type === 'component') {
+        const folder = renamingItem.folder;
+        const folderPath = folder.path === '/' ? '' : folder.path;
+        const fullName = folderPath ? `${folderPath}/${newName}` : newName;
+
+        if (ProjectModel.instance.getComponentWithName(fullName)) {
+          return { valid: false, error: 'A component with this name already exists' };
+        }
+      } else if (renamingItem?.type === 'folder') {
+        // Check for duplicate folder
+        const parentPath = renamingItem.path.substring(0, renamingItem.path.lastIndexOf('/'));
+        const newPath = parentPath ? `${parentPath}/${newName}` : newName;
+
+        const components = ProjectModel.instance.getComponents();
+        const hasConflict = components.some((comp) => comp.name.startsWith(newPath + '/'));
+
+        if (hasConflict) {
+          // Check if it's just the same folder
+          if (newPath !== renamingItem.path) {
+            return { valid: false, error: 'A folder with this name already exists' };
+          }
+        }
+      }
+
+      return { valid: true };
+    },
+    [renamingItem]
+  );
+
+  return {
+    renamingItem,
+    renameValue,
+    setRenameValue,
+    startRename,
+    cancelRename,
+    validateName
+  };
+}
+```
+
+---
+
+## Step 2: Create Rename Input Component
+
+### 2.1 Create `components/RenameInput.tsx`
+
+```typescript
+/**
+ * RenameInput
+ *
+ * Inline input field for renaming components/folders.
+ */
+
+import React, { useCallback, useEffect, useRef } from 'react';
+
+import css from '../ComponentsPanel.module.scss';
+
+interface RenameInputProps {
+  value: string;
+  onChange: (value: string) => void;
+  onConfirm: () => void;
+  onCancel: () => void;
+  level: number;
+}
+
+export function RenameInput({ value, onChange, onConfirm, onCancel, level }: RenameInputProps) {
+  const inputRef = useRef<HTMLInputElement>(null);
+  const indent = level * 12;
+
+  // Auto-focus and select all on mount
+  useEffect(() => {
+    if (inputRef.current) {
+      inputRef.current.focus();
+      inputRef.current.select();
+    }
+  }, []);
+
+  const handleKeyDown = useCallback(
+    (e: React.KeyboardEvent) => {
+      if (e.key === 'Enter') {
+        e.preventDefault();
+        onConfirm();
+      } else if (e.key === 'Escape') {
+        e.preventDefault();
+        onCancel();
+      }
+    },
+    [onConfirm, onCancel]
+  );
+
+  const handleBlur = useCallback(() => {
+    // Cancel on blur
+    onCancel();
+  }, [onCancel]);
+
+  return (
+    <div className={css.RenameContainer} style={{ paddingLeft: `${indent + 23}px` }}>
+      <input
+        ref={inputRef}
+        type="text"
+        className={css.RenameInput}
+        value={value}
+        onChange={(e) => onChange(e.target.value)}
+        onKeyDown={handleKeyDown}
+        onBlur={handleBlur}
+      />
+    </div>
+  );
+}
+```
+
+---
+
+## Step 3: Integrate Rename into Tree Items
+
+### 3.1 Update `ComponentItem.tsx`
+
+Add double-click and rename mode:
+
+```typescript
+export function ComponentItem({
+  component,
+  level,
+  isSelected,
+  onClick,
+  onDragStart,
+  onDoubleClick,
+  isRenaming,
+  renameValue,

+  onRenameConfirm,
+  onRenameCancel
+}: ComponentItemProps) {
+  // ... existing code ...
+
+  if (isRenaming) {
+    return (
+      <RenameInput
+        value={renameValue}
+        onChange={onRenameChange}
+        onConfirm={onRenameConfirm}
+        onCancel={onRenameCancel}
+        level={level}
+      />
+    );
+  }
+
+  return (
+    <div
+      ref={itemRef}
+      className={classNames(css.TreeItem, {
+        [css.Selected]: isSelected
+      })}
+      style={{ paddingLeft: `${indent + 23}px` }}
+      onClick={onClick}
+      onDoubleClick={() => onDoubleClick?.(component)}
+      onContextMenu={handleContextMenu}
+      onMouseDown={handleMouseDown}
+      onMouseMove={handleMouseMove}
+      onMouseUp={handleMouseUp}
+    >
+      {/* ... existing content ... */}
+    </div>
+  );
+}
+```
+
+### 3.2 Update `FolderItem.tsx`
+
+Add double-click and rename mode:
+
+```typescript
+export function FolderItem({
+  folder,
+  level,
+  isExpanded,
+  isSelected,
+  onCaretClick,
+  onClick,
+  onDragStart,

+  canAcceptDrop,
+  onDoubleClick,
+  isRenaming,
+  renameValue,
+  onRenameChange,
+  onRenameConfirm,
+  onRenameCancel,
+  children
+}: FolderItemProps) {
+  // ... existing code ...
+
+  if (isRenaming) {
+    return (
+      <>
+        <RenameInput
+          value={renameValue}
+          onChange={onRenameChange}
+          onConfirm={onRenameConfirm}
+          onCancel={onRenameCancel}
+          level={level}
+        />
+        {children}
+      </>
+    );
+  }
+
+  return (
+    <>
+      <div
+        ref={itemRef}
+        className={classNames(css.TreeItem, {
+          [css.Selected]: isSelected,
+          [css.DropTarget]: isDropTarget
+        })}
+        style={{ paddingLeft: `${indent + 10}px` }}
+        onContextMenu={handleContextMenu}
+        onDoubleClick={() => onDoubleClick?.(folder)}

+      >
+        {/* ... existing content ... */}
+      </div>
+      {children}
+    </>
+  );
+}
+```
+
+---
+
+## Step 4: Implement Rename Execution
+
+### 4.1 Update `useComponentActions.ts`
+
+Complete the rename handler:
+
+```typescript
+const handleRename = useCallback((item: TreeNode, newName: string) => {
+  if (item.type === 'component') {
+    const component = item.component;
+    const folder = item.folder;
+    const folderPath = folder.path === '/' ? '' : folder.path;
+    const newFullName = folderPath ? `${folderPath}/${newName}` : newName;
+    const oldName = component.name;
+
+    UndoQueue.instance.pushAndDo(
+      new UndoActionGroup({
+        label: `Rename ${component.name} to ${newName}`,
+        do: () => {
+          ProjectModel.instance.renameComponent(component, newFullName);
+        },
+        undo: () => {
+          ProjectModel.instance.renameComponent(component, oldName);
+        }
+      })

+    // Rename folder (rename all components in folder)
+    const oldPath = item.path;
+    const parentPath = oldPath.substring(0, oldPath.lastIndexOf('/'));
+    const newPath = parentPath ? `${parentPath}/${newName}` : newName;
+
+    const components = ProjectModel.instance.getComponents();
+    const componentsToRename = components.filter((comp) => comp.name.startsWith(oldPath + '/'));
+
+    if (componentsToRename.length === 0) {
+      ToastLayer.showInfo('Folder is empty');
+      return;
+    }
+
+    const renames = componentsToRename.map((comp) => ({
+      component: comp,
+      oldName: comp.name,
+      newName: comp.name.replace(oldPath, newPath)
+    }));
+
+    UndoQueue.instance.pushAndDo(
+      new UndoActionGroup({
+        label: `Rename folder ${item.name} to ${newName}`,
+        do: () => {
+          renames.forEach(({ component, newName }) => {
+            ProjectModel.instance.renameComponent(component, newName);
+          });
+        },
+        undo: () => {
+          renames.forEach(({ component, oldName }) => {
+            ProjectModel.instance.renameComponent(component, oldName);
+          });
+        }
+      })
+    );
+  }
+}, []);
+```
+
+---
+
+## Step 5: Add Rename Styles
+
+### 5.1 Update `ComponentsPanel.module.scss`
+
+```scss
+.RenameContainer {
+  display: flex;
+  align-items: center;
+  padding: 6px 10px;
+}
+
+.RenameInput {
+  flex: 1;
+  padding: 4px 8px;
+  font: 11px var(--font-family-regular);
+  color: var(--theme-color-fg-default);
+  background-color: var(--theme-color-bg-3);
+  border: 1px solid var(--theme-color-primary);
+  border-radius: 3px;
+  outline: none;
+
+  &:focus {
+    border-color: var(--theme-color-primary);
+    box-shadow: 0 0 0 2px var(--theme-color-primary-transparent);
+  }
+}
+```
+
+---
+
+## Step 6: Wire Up Rename
+
+### 6.1 Update `ComponentsPanel.tsx`
+
+```typescript
+export function ComponentsPanel(props: ComponentsPanelProps) {
+  const { treeData, expandedFolders, selectedId, toggleFolder, handleItemClick } = useComponentsPanel({
+    hideSheets,
+    lockCurrentSheetName
+  });
+
+  const { handleMakeHome, handleDelete, handleDuplicate, handleRename, handleDropOn } = useComponentActions();
+
+  const { renamingItem, renameValue, setRenameValue, startRename, cancelRename, validateName } = useRenameMode();
+
+  const handleRenameConfirm = useCallback(() => {
+    if (!renamingItem) return;
+
+    const validation = validateName(renameValue);
+    if (!validation.valid) {
+      ToastLayer.showError(validation.error || 'Invalid name');
+      return;
+    }
+
+    if (renameValue !== renamingItem.name) {
+      handleRename(renamingItem, renameValue);
+    }
+
+    cancelRename();
+  }, [renamingItem, renameValue, validateName, handleRename, cancelRename]);
+
+  return (
+    <div className={css.ComponentsPanel}>
+      {/* ... */}
+
+      <ComponentTree
+        nodes={treeData}
+        expandedFolders={expandedFolders}
+        selectedId={selectedId}
+        onItemClick={handleItemClick}
+        onCaretClick={toggleFolder}
+        onDragStart={startDrag}
+        onDrop={handleDrop}
+        canAcceptDrop={canDrop}
+        onDoubleClick={startRename}
+        renamingItem={renamingItem}
+        renameValue={renameValue}
+        onRenameChange={setRenameValue}
+        onRenameConfirm={handleRenameConfirm}
+        onRenameCancel={cancelRename}
+      />
+    </div>
+  );
+}
+```
+
+---
+

+# Phase 6: Sheet Selector
+
+**Estimated Time:** 30 minutes  
+**Complexity:** Low  
+**Prerequisites:** Phase 5 complete (inline rename working)
+
+## Overview
+
+Implement sheet/tab switching functionality. The sheet selector displays tabs for different sheets and filters the component tree to show only components from the selected sheet. Respects `hideSheets` and `lockCurrentSheetName` props.
+
+---
+
+## Goals
+
+- ✅ Display sheet tabs from ProjectModel
+- ✅ Filter component tree by selected sheet
+- ✅ Handle sheet selection
+- ✅ Respect `hideSheets` prop
+- ✅ Respect `lockCurrentSheetName` prop
+- ✅ Show/hide based on `showSheetList` prop
+
+---
+
+## Step 1: Create Sheet Selector Component
+
+### 1.1 Create `components/SheetSelector.tsx`
+
+```typescript
+/**
+ * SheetSelector
+ *
+ * Displays tabs for project sheets and handles sheet selection.
+ */
+
+import classNames from 'classnames';
+import React from 'react';
+
+import css from '../ComponentsPanel.module.scss';
+import { SheetData } from '../types';
+
+interface SheetSelectorProps {
+  sheets: SheetData[];
+  selectedSheet: string;
+  onSheetSelect: (sheetName: string) => void;
+}
+
+export function SheetSelector({ sheets, selectedSheet, onSheetSelect }: SheetSelectorProps) {
+  if (sheets.length === 0) {
+    return null;
+  }
+
+  return (
+    <div className={css.SheetsSection}>
+      <div className={css.SheetsHeader}>Sheets</div>
+      <div className={css.SheetsList}>
+        {sheets.map((sheet) => (
+          <div
+            key={sheet.name}
+            className={classNames(css.SheetItem, {
+              [css.Selected]: sheet.name === selectedSheet
+            })}
+            onClick={() => onSheetSelect(sheet.name)}
+          >
+            {sheet.displayName}
+          </div>
+        ))}
+      </div>
+    </div>
+  );
+}
+```
+
+---
+
+## Step 2: Update Panel State Hook
+
+### 2.1 Update `hooks/useComponentsPanel.ts`
+
+Add sheet management:
+
+```typescript
+export function useComponentsPanel(options: UseComponentsPanelOptions = {}) {
+  const { hideSheets = [], lockCurrentSheetName } = options;
+
+  // Local state
+  const [expandedFolders, setExpandedFolders] = useState<Set<string>>(new Set(['/']));
+  const [selectedId, setSelectedId] = useState<string | undefined>();
+  const [updateCounter, setUpdateCounter] = useState(0);
+  const [currentSheet, setCurrentSheet] = useState<string>(() => {
+    if (lockCurrentSheetName) return lockCurrentSheetName;
+    return 'default'; // Or get from ProjectModel
+  });
+
+  // Subscribe to ProjectModel events
+  useEffect(() => {
+    const handleUpdate = () => {
+      setUpdateCounter((c) => c + 1);
+    };
+
+    ProjectModel.instance.on('componentAdded', handleUpdate);
+    ProjectModel.instance.on('componentRemoved', handleUpdate);
+    ProjectModel.instance.on('componentRenamed', handleUpdate);
+    ProjectModel.instance.on('rootComponentChanged', handleUpdate);
+
+    return () => {
+      ProjectModel.instance.off('componentAdded', handleUpdate);
+      ProjectModel.instance.off('componentRemoved', handleUpdate);
+      ProjectModel.instance.off('componentRenamed', handleUpdate);
+      ProjectModel.instance.off('rootComponentChanged', handleUpdate);
+    };
+  }, []);
+
+  // Build sheets list
+  const sheets = useMemo(() => {
+    return buildSheetsList(ProjectModel.instance, hideSheets);
+  }, [updateCounter, hideSheets]);
+
+  // Build tree structure (filtered by current sheet)
+  const treeData = useMemo(() => {
+    return buildTreeFromProject(ProjectModel.instance, hideSheets, currentSheet);
+  }, [updateCounter, hideSheets, currentSheet]);
+
+  // Handle sheet selection
+  const handleSheetSelect = useCallback(
+    (sheetName: string) => {
+      if (!lockCurrentSheetName) {
+        setCurrentSheet(sheetName);
+      }
+    },
+    [lockCurrentSheetName]
+  );
+
+  return {
+    treeData,
+    expandedFolders,
+    selectedId,
+    sheets,
+    currentSheet,
+    toggleFolder,
+    handleItemClick,
+    handleSheetSelect
+  };
+}
+
+/**
+ * Build list of sheets from ProjectModel
+ */
+function buildSheetsList(project: ProjectModel, hideSheets: string[]): SheetData[] {
+  const sheets: SheetData[] = [];
+  const components = project.getComponents();
+
+  // Extract unique sheet names
+  const sheetNames = new Set<string>();
+  components.forEach((comp) => {
+    const sheetName = getSheetForComponent(comp.name);
+    if (!hideSheets.includes(sheetName)) {
+      sheetNames.add(sheetName);
+    }
+  });
+
+  // Convert to SheetData array
+  sheetNames.forEach((sheetName) => {
+    sheets.push({
+      name: sheetName,
+      displayName: sheetName === 'default' ? 'Default' : sheetName,
+      isDefault: sheetName === 'default',
+      isSelected: false // Will be set by parent
+    });
+  });
+
+  // Sort: default first, then alphabetical
+  sheets.sort((a, b) => {
+    if (a.isDefault) return -1;
+    if (b.isDefault) return 1;
+    return a.displayName.localeCompare(b.displayName);
+  });
+
+  return sheets;
+}
+
+function getSheetForComponent(componentName: string): string {
+  if (componentName.includes('/')) {
+    const parts = componentName.split('/');
+    // Check if first part is a sheet name
+    // Sheets typically start with uppercase or have specific patterns
+    return parts[0];
+  }
+  return 'default';
+}
+```
+
+---
+
+## Step 3: Integrate Sheet Selector
+
+### 3.1 Update `ComponentsPanel.tsx`
+
+Add sheet selector to panel:
+
+```typescript
+export function ComponentsPanel(props: ComponentsPanelProps) {
+  const { showSheetList = true, hideSheets = [], componentTitle = 'Components', lockCurrentSheetName } = props;
+
+  const {
+    treeData,
+    expandedFolders,
+    selectedId,
+    sheets,
+    currentSheet,
+    toggleFolder,
+    handleItemClick,
+    handleSheetSelect
+  } = useComponentsPanel({
+    hideSheets,
+    lockCurrentSheetName
+  });
+
+  // ... other hooks ...
+
+  return (
+    <div className={css.ComponentsPanel}>
+      <div className={css.Header}>
+        <div className={css.Title}>{componentTitle}</div>
+        <button ref={setAddButtonRef} className={css.AddButton} title="Add component" onClick={handleAddButtonClick}>
+          <div className={css.AddIcon}>+</div>
+        </button>
+      </div>
+
+      {showSheetList && sheets.length > 0 && (
+        <SheetSelector sheets={sheets} selectedSheet={currentSheet} onSheetSelect={handleSheetSelect} />
+      )}
+
+      <div className={css.ComponentsHeader}>
+        <div className={css.Title}>Components</div>
+      </div>
+
+      <div className={css.ComponentsScroller}>
+        <div className={css.ComponentsList}>
+          <ComponentTree
+            nodes={treeData}
+            expandedFolders={expandedFolders}
+            selectedId={selectedId}
+            onItemClick={handleItemClick}
+            onCaretClick={toggleFolder}
+            onDragStart={startDrag}
+            onDrop={handleDrop}
+            canAcceptDrop={canDrop}
+            onDoubleClick={startRename}
+            renamingItem={renamingItem}
+            renameValue={renameValue}
+            onRenameChange={setRenameValue}
+            onRenameConfirm={handleRenameConfirm}
+            onRenameCancel={cancelRename}
+          />
+        </div>
+      </div>
+
+      {showAddMenu && addButtonRef && (
+        <AddComponentMenu targetElement={addButtonRef} onClose={() => setShowAddMenu(false)} parentPath="" />
+      )}
+    </div>
+  );
+}
+```
+
+---
+
+## Step 4: Add Sheet Styles
+
+### 4.1 Update `ComponentsPanel.module.scss`
+
+Add sheet selection styling:
+
+```scss
+.SheetsSection {
+  border-bottom: 1px solid var(--theme-color-border-default);
+}
+
+.SheetsHeader {
+  display: flex;
+  align-items: center;
+  padding: 8px 10px;
+  font: 11px var(--font-family-bold);
+  color: var(--theme-color-fg-default);
+  background-color: var(--theme-color-bg-2);
+  text-transform: uppercase;
+  letter-spacing: 0.5px;
+}
+
+.SheetsList {
+  max-height: 250px;
+  overflow-y: auto;
+  overflow-x: hidden;
+}
+
+.SheetItem {
+  padding: 8px 10px 8px 30px;
+  font: 11px var(--font-family-regular);
+  color: var(--theme-color-fg-default);
+  cursor: pointer;
+  transition: background-color 0.15s ease;
+  user-select: none;
+
+  &:hover {
+    background-color: var(--theme-color-bg-3);
+  }
+
+  &.Selected {
+    background-color: var(--theme-color-primary-transparent);
+    color: var(--theme-color-primary);
+    font-weight: 600;
+  }
+}
+```
+
+---
+
+## Step 5: Testing
+
+### 5.1 Verification Checklist
+
+- [ ] Sheet tabs appear when `showSheetList` is true
+- [ ] Sheet tabs hidden when `showSheetList` is false
+- [ ] Correct sheets displayed (excluding hidden sheets)
+- [ ] Clicking sheet selects it
+- [ ] Selected sheet highlights correctly
+- [ ] Component tree filters by selected sheet
+- [ ] Default sheet displays first
+- [ ] `lockCurrentSheetName` locks to specific sheet
+- [ ] No console errors
+
+### 5.2 Test Edge Cases
+
+- [ ] Project with no sheets (only default)
+- [ ] Project with many sheets
+- [ ] Switching sheets with expanded folders
+- [ ] Switching sheets with selected component
+- [ ] Locked sheet (should not allow switching)
+- [ ] Hidden sheets don't appear
+
+---
+
+## Common Issues & Solutions
+
+### Issue: Sheets don't appear
+
+**Solution:** Check that `showSheetList` prop is true and that ProjectModel has components in sheets.
+
+### Issue: Sheet filtering doesn't work
+
+**Solution:** Verify `buildTreeFromProject` correctly filters components by sheet name.
+
+### Issue: Hidden sheets still appear
+
+**Solution:** Check that `hideSheets` array includes the correct sheet names.
+
+### Issue: Can't switch sheets when locked
+
+**Solution:** This is expected behavior when `lockCurrentSheetName` is set.
+
+---
+
+## Success Criteria
+
+✅ **Phase 6 is complete when:**
+
+1. Sheet tabs display correctly
+2. Sheet selection works
+3. Component tree filters by selected sheet
+4. Hidden sheets are excluded
+5. Locked sheet prevents switching
+6. showSheetList prop controls visibility
+7. No console errors
+

+# Phase 7: Polish & Cleanup
+
+**Estimated Time:** 1 hour  
+**Complexity:** Low  
+**Prerequisites:** Phase 6 complete (sheet selector working)
+
+## Overview
+
+Final polish, remove legacy files, ensure all functionality works correctly, and prepare the component for TASK-004 (migration status badges). This phase ensures the migration is complete and production-ready.
+
+---
+
+## Goals
+
+- ✅ Polish UI/UX (spacing, hover states, focus states)
+- ✅ Remove legacy files
+- ✅ Clean up code (remove TODOs, add missing JSDoc)
+- ✅ Verify all functionality works
+- ✅ Prepare extension points for TASK-004
+- ✅ Update documentation
+- ✅ Final testing pass
+
+---
+
+## Step 1: UI Polish
+
+### 1.1 Review All Styles
+
+Check and fix any styling inconsistencies:
+
+```scss
+// Verify all spacing is consistent
+.TreeItem {
+  padding: 6px 10px; // Should match across all items
+}
+
+// Verify hover states work
+.TreeItem:hover {
+  background-color: var(--theme-color-bg-3);
+}
+
+// Verify selection states are clear
+.TreeItem.Selected {
+  background-color: var(--theme-color-primary-transparent);
+  color: var(--theme-color-primary);
+}
+
+// Verify focus states for accessibility
+.RenameInput:focus {
+  border-color: var(--theme-color-primary);
+  box-shadow: 0 0 0 2px var(--theme-color-primary-transparent);
+}
+```
+
+### 1.2 Test Color Tokens
+
+Verify all colors use design tokens (no hardcoded hex values):
+
+```bash
+# Search for hardcoded colors
+grep -r "#[0-9a-fA-F]\{3,6\}" packages/noodl-editor/src/editor/src/views/panels/ComponentsPanel/
+```
+
+If any found, replace with appropriate tokens from `--theme-color-*`.
+
+### 1.3 Test Dark Theme (if applicable)
+
+If OpenNoodl supports theme switching, test the panel in dark theme to ensure all colors are legible.
+
+---
+
+## Step 2: Code Cleanup
+
+### 2.1 Remove TODO Comments
+
+Search for and resolve all TODO comments:
+
+```bash
+grep -rn "TODO" packages/noodl-editor/src/editor/src/views/panels/ComponentsPanel/
+```
+
+Either implement the TODOs or remove them if they're no longer relevant.
+
+### 2.2 Remove TSFixme Types
+
+Ensure no TSFixme types were added:
+
+```bash
+grep -rn "TSFixme" packages/noodl-editor/src/editor/src/views/panels/ComponentsPanel/
+```
+
+Replace any with proper types.
+
+### 2.3 Add JSDoc Comments
+
+Ensure all exported functions and components have JSDoc:
+
+````typescript
+/**
+ * ComponentsPanel
+ *
+ * Modern React implementation of the components sidebar panel.
+ * Displays project component hierarchy with folders, allows drag-drop reorganization,
+ * and provides context menus for component/folder operations.
+ *
+ * @example
+ * ```tsx
+ * <ComponentsPanel
+ *   nodeGraphEditor={editor}
+ *   showSheetList={true}
+ *   hideSheets={['__cloud__']}
+ * />
+ * ```
+ */
+export function ComponentsPanel(props: ComponentsPanelProps) {
+  // ...
+}
+````
+
+### 2.4 Clean Up Imports
+
+Remove unused imports and organize them:
+
+```typescript
+// External packages (alphabetical)
+
+import PopupLayer from '@noodl-views/popuplayer';
+import classNames from 'classnames';
+import React, { useCallback, useEffect, useState } from 'react';
+
+import { ProjectModel } from '@noodl-models/projectmodel';
+import { UndoQueue } from '@noodl-models/undo-queue-model';
+
+// Internal packages (alphabetical by alias)
+import { IconName } from '@noodl-core-ui/components/common/Icon';
+
+// Relative imports
+import { ComponentTree } from './components/ComponentTree';
+import css from './ComponentsPanel.module.scss';
+import { useComponentsPanel } from './hooks/useComponentsPanel';
+import { ComponentsPanelProps } from './types';
+```
+
+---
+
+## Step 3: Remove Legacy Files
+
+### 3.1 Verify All Functionality Works
+
+Before removing legacy files, thoroughly test the new implementation:
+
+- [ ] All features from old panel work in new panel
+- [ ] No regressions identified
+- [ ] All tests pass
+
+### 3.2 Update Imports
+
+Find all files that import the old ComponentsPanel:
+
+```bash
+grep -r "from.*componentspanel/ComponentsPanel" packages/noodl-editor/src/
+```
+
+Update to import from new location:
+
+```typescript
+// Old
+
+// New
+import { ComponentsPanel } from './views/panels/ComponentsPanel';
+import { ComponentsPanelView } from './views/panels/componentspanel/ComponentsPanel';
+```
+
+### 3.3 Delete Legacy Files
+
+Once all imports are updated and verified:
+
+```bash
+# Delete old implementation (DO NOT run this until 100% sure)
+# rm packages/noodl-editor/src/editor/src/views/panels/componentspanel/ComponentsPanel.ts
+# rm packages/noodl-editor/src/editor/src/templates/componentspanel.html
+```
+
+**IMPORTANT:** Keep `ComponentsPanelFolder.ts` and `ComponentTemplates.ts` as they're reused.
+
+---
+
+## Step 4: Prepare for TASK-004
+
+### 4.1 Add Migration Status Type
+
+In `types.ts`, add placeholder for migration status:
+
+```typescript
+/**
+ * Migration status for components (for TASK-004)
+ */
+export type MigrationStatus = 'needs-review' | 'ai-migrated' | 'auto' | 'manually-fixed' | null;
+
+export interface ComponentItemData {
+  type: 'component';
+  component: ComponentModel;
+  folder: ComponentsPanelFolder;
+  name: string;
+  fullName: string;
+  isSelected: boolean;
+  isRoot: boolean;
+  isPage: boolean;
+  isCloudFunction: boolean;
+  isVisual: boolean;
+  canBecomeRoot: boolean;
+  hasWarnings: boolean;
+
+  // Migration status (for TASK-004)
+  migrationStatus?: MigrationStatus;
+}
+```
+
+### 4.2 Add Badge Placeholder in ComponentItem
+
+```typescript
+export function ComponentItem({ component, level, isSelected, onClick }: ComponentItemProps) {
+  // ... existing code ...
+
+  return (
+    <div className={css.TreeItem} onClick={onClick}>
+      <div className={css.ItemContent}>
+        <div className={css.Icon}>{icon}</div>
+        <div className={css.Label}>{component.name}</div>
+
+        {/* Migration badge (for TASK-004) */}
+        {component.migrationStatus && (
+          <div className={css.MigrationBadge} data-status={component.migrationStatus}>
+            {/* Badge will be implemented in TASK-004 */}
+          </div>
+        )}
+
+        {component.hasWarnings && <div className={css.Warning}>!</div>}
+      </div>
+    </div>
+  );
+}
+```
+
+### 4.3 Add Filter Placeholder in Panel Header
+
+```typescript
+<div className={css.Header}>
+  <div className={css.Title}>{componentTitle}</div>
+

+
+## Step 5: Documentation
+
+### 5.1 Update CHANGELOG.md
+
+Add final entry to CHANGELOG:
+
+```markdown
+## [2024-12-21] - Migration Complete
+
+### Summary
+
+Completed ComponentsPanel React migration. All 7 phases implemented and tested.
+
+### Files Created
+
+- All files in `views/panels/ComponentsPanel/` directory
+
+### Files Modified
+
+- `router.setup.ts` - Updated ComponentsPanel import
+
+### Files Removed
+
+- `views/panels/componentspanel/ComponentsPanel.ts` (legacy)
+- `templates/componentspanel.html` (legacy)
+
+### Technical Notes
+
+- Full feature parity achieved
+- All functionality uses UndoQueue
+- Ready for TASK-004 badges/filters integration
+
+### Testing Notes
+
+- All manual tests passed
+- No console errors
+- Performance is good even with large component trees
+
+### Next Steps
+
+- TASK-004 Part 2: Add migration status badges
+- TASK-004 Part 3: Add filter system
+```
+
+### 5.2 Create Migration Pattern Document
+
+Document the pattern for future panel migrations:
+
+**File:** `dev-docs/reference/PANEL-MIGRATION-PATTERN.md`
+
+```markdown
+# Panel Migration Pattern
+
+Based on ComponentsPanel React migration (TASK-004B).
+
+## Steps
+
+1. **Foundation** - Create directory, types, basic component
+2. **Data Integration** - Connect to models, subscribe to events
+3. **UI Features** - Implement interactions (menus, selection, etc.)
+4. **Advanced Features** - Implement complex features (drag-drop, inline editing)
+5. **Polish** - Clean up, remove legacy files
+
+## Key Patterns
+
+### Model Subscription
+
+Use `useEffect` with cleanup:
+
+\`\`\`typescript
+useEffect(() => {
+const handler = () => setUpdateCounter(c => c + 1);
+Model.instance.on('event', handler);
+return () => Model.instance.off('event', handler);
+}, []);
+\`\`\`
+
+### UndoQueue Integration
+
+All mutations should use UndoQueue:
+
+\`\`\`typescript
+UndoQueue.instance.pushAndDo(new UndoActionGroup({
+label: 'Action description',
+do: () => { /_ perform action _/ },
+undo: () => { /_ reverse action _/ }
+}));
+\`\`\`

+# TASK-004B Implementation Phases
+
+This directory contains detailed implementation guides for each phase of the ComponentsPanel React migration.
+
+## Phase Overview
+
+| Phase | Name                                            | Time | Complexity | Status         |
+| ----- | ----------------------------------------------- | ---- | ---------- | -------------- |

+| 2     | [Tree Rendering](./PHASE-2-TREE-RENDERING.md)   | 1-2h | Medium     | 📝 In Progress |
+| 3     | [Context Menus](./PHASE-3-CONTEXT-MENUS.md)     | 1h   | Low        | ⏳ Pending     |
+| 4     | [Drag-Drop](./PHASE-4-DRAG-DROP.md)             | 2h   | High       | ⏳ Pending     |
+| 5     | [Inline Rename](./PHASE-5-INLINE-RENAME.md)     | 1h   | Medium     | ⏳ Pending     |
+| 6     | [Sheet Selector](./PHASE-6-SHEET-SELECTOR.md)   | 30m  | Low        | ⏳ Pending     |
+| 7     | [Polish & Cleanup](./PHASE-7-POLISH-CLEANUP.md) | 1h   | Low        | ⏳ Pending     |
+
+**Total Estimated Time:** 6-8 hours
+
+## Implementation Strategy
+
+### Sequential Implementation (Recommended)
+
+Implement phases in order 1→7. Each phase builds on the previous:
+
+- Phase 1 creates the foundation
+- Phase 2 adds data display
+- Phase 3 adds user interactions
+- Phase 4 adds drag-drop
+- Phase 5 adds inline editing
+- Phase 6 adds sheet switching
+- Phase 7 polishes and prepares for TASK-004
+
+### Parallel Implementation (Advanced)
+
+If working with multiple developers:
+
+- **Developer A:** Phases 1, 2, 6 (core rendering)
+- **Developer B:** Phases 3, 5 (user interactions)
+- **Developer C:** Phase 4 (drag-drop)
+- **Developer D:** Phase 7 (polish)
+
+Merge in order: 1 → 2 → 6 → 3 → 5 → 4 → 7
+
+## Quick Start
+
+1. Read [Phase 1: Foundation](./PHASE-1-FOUNDATION.md)
+2. Implement and test Phase 1
+3. Verify all Phase 1 success criteria
+4. Move to next phase
+5. Repeat until complete
+
+## Testing Strategy
+
+### After Each Phase
+
+- Run `npm run dev`
+- Manually test new features
+- Check console for errors
+- Verify TypeScript compiles
+
+### Integration Testing
+
+After Phase 7, test:
+
+- All context menu actions
+- Drag-drop all scenarios
+- Rename validation
+- Sheet switching
+- Selection persistence
+- Undo/redo for all operations
+
+## Common Patterns
+
+### ProjectModel Integration
+
+```typescript
+import { ProjectModel } from '@noodl-models/projectmodel';
+
+// Subscribe to events
+useEffect(() => {
+  const handleComponentAdded = (args) => {
+    // Handle addition
+  };
+
+  ProjectModel.instance.on('componentAdded', handleComponentAdded);
+
+  return () => {
+    ProjectModel.instance.off('componentAdded', handleComponentAdded);
+  };
+}, []);
+```
+
+### UndoQueue Pattern
+
+```typescript
+import { UndoQueue, UndoActionGroup } from '@noodl-models/undo-queue-model';
+
+UndoQueue.instance.pushAndDo(
+  new UndoActionGroup({
+    label: 'action description',
+    do: () => {
+      // Perform action
+    },
+    undo: () => {
+      // Reverse action
+    }
+  })
+);
+```
+
+### PopupMenu Pattern
+
+```typescript
+import PopupLayer from '@noodl-views/popuplayer';
+
+const menu = new PopupLayer.PopupMenu({
+  items: [
+    {
+      icon: IconName.Plus,
+      label: 'Add Component',
+      onClick: () => {
+        /* handler */
+      }
+    },
+    { type: 'divider' },
+    {
+      icon: IconName.Trash,
+      label: 'Delete',
+      onClick: () => {
+        /* handler */
+      }
+    }
+  ]
+});
+
+PopupLayer.instance.showPopup({
+  content: menu,
+  attachTo: buttonElement,
+  position: 'bottom'
+});
+```
+
+## Troubleshooting
+
+### Phase 1 Issues
+
+- **Panel doesn't appear:** Check SidebarModel registration
+- **Styles not loading:** Verify webpack CSS module config
+- **TypeScript errors:** Check @noodl-models imports
+
+### Phase 2 Issues
+
+- **Tree not updating:** Verify ProjectModel event subscriptions
+- **Wrong components shown:** Check sheet filtering logic
+- **Selection not working:** Verify NodeGraphEditor integration
+
+### Phase 3 Issues
+
+- **Menu doesn't show:** Check PopupLayer z-index
+- **Actions fail:** Verify UndoQueue integration
+- **Icons missing:** Check IconName imports
+
+### Phase 4 Issues
+
+- **Drag not starting:** Verify PopupLayer.startDragging call
+- **Drop validation wrong:** Check getAcceptableDropType logic
+- **Undo broken:** Verify undo action includes all state changes
+
+### Phase 5 Issues
+
+- **Rename input not appearing:** Check CSS positioning
+- **Name validation failing:** Verify ProjectModel.getComponentWithName
+- **Focus lost:** Ensure input autoFocus and blur handlers
+
+### Phase 6 Issues
+
+- **Sheets not filtering:** Check currentSheet state
+- **Hidden sheets appear:** Verify hideSheets prop filtering
+
+### Phase 7 Issues
+
+- **Old panel still showing:** Remove old require() in router.setup.ts
+- **Tests failing:** Update test imports to new location
