+# Code Quality Fixes - Deployment Issues Resolved
+
+**Date**: November 22, 2025
+**Branch**: `claude/add-astrology-tools-018kmiNMADwf7hNz1YQwTqS6`
+**Commit**: `941c574`
+**Status**: ✅ READY FOR DEPLOYMENT
+
+---
+
+## Issues Fixed
+
+### 1. ❌ Undefined Variable Reference (Dashboard.tsx:569)
+
+**Issue**: Reference to undefined variable `onAskAI`
+```typescript
+// BEFORE (line 569)
+{onAskAI && (
+  <button onClick={() => handleMagicExpand(...)}>
+    Ask AI
+  </button>
+)}
+```
+
+**Problem**:
+- `onAskAI` was never defined in Dashboard component
+- Would cause runtime error: `ReferenceError: onAskAI is not defined`
+- CodeRabbit/ESLint would flag as: `'onAskAI' is not defined`
+
+**Fix**:
+```typescript
+// AFTER (line 569)
+<button onClick={() => handleMagicExpand(...)}>
+  Ask AI
+</button>
+```
+
+**Reason**: `handleMagicExpand` is always available, no conditional needed
+
+---
+
+### 2. ⚠️ React Hook Dependency Array Incomplete (OnboardingTour.tsx:86)
+
+**Issue**: Missing dependency in useEffect
+```typescript
+// BEFORE
+useEffect(() => {
+  const handleEscape = (e: KeyboardEvent) => {
+    if (e.key === 'Escape' && isOpen) {
+      handleSkip();  // ← Function not in dependency array
+    }
+  };
+  window.addEventListener('keydown', handleEscape);
+  return () => window.removeEventListener('keydown', handleEscape);
+}, [isOpen]);  // ← Missing handleSkip
+```
+
+**Problem**:
+- ESLint error: `React Hook useEffect has a missing dependency: 'handleSkip'`
+- Could cause stale closures
+- CodeRabbit would flag with: `exhaustive-deps` warning
+
+**Fix**:
+```typescript
+// AFTER
+useEffect(() => {
+  const handleEscape = (e: KeyboardEvent) => {
+    if (e.key === 'Escape' && isOpen) {
+      onClose();  // ← Direct call, stable reference
+    }
+  };
+  window.addEventListener('keydown', handleEscape);
+  return () => window.removeEventListener('keydown', handleEscape);
+}, [isOpen, onClose]);  // ← Complete dependency array
+```
+
+**Bonus**: Also moved function definitions before useEffect for better code organization
+
+---
+
+### 3. ⚠️ Memory Leak - Missing Cleanup (Dashboard.tsx:164)
+
+**Issue**: setTimeout without cleanup
+```typescript
+// BEFORE
+React.useEffect(() => {
+  const hasCompletedTour = localStorage.getItem('celestia_onboarding_completed');
+  if (!hasCompletedTour) {
+    setTimeout(() => setTourOpen(true), 1000);  // ← No cleanup
+  }
+}, []);
+```
+
+**Problem**:
+- If component unmounts before timeout fires, memory leak occurs
+- setState called on unmounted component warning
+- CodeRabbit would flag: "Effect may cause memory leak"
+
+**Fix**:
+```typescript
+// AFTER
+React.useEffect(() => {
+  const hasCompletedTour = localStorage.getItem('celestia_onboarding_completed');
+  if (!hasCompletedTour) {
+    const timer = setTimeout(() => setTourOpen(true), 1000);
+    return () => clearTimeout(timer);  // ← Cleanup function
+  }
+}, []);
+```
+
+---
+
+### 4. 🗑️ Development File in Production (test-calculations.js)
+
+**Issue**: Test file included in repository
+```javascript
+// test-calculations.js
+import * as AstroCalc from './services/astronomyService.ts';
+// ... test code ...
+```
+
+**Problem**:
+- Increases bundle size unnecessarily
+- Not needed in production
+- Should be in .gitignore or separate test directory
+
+**Fix**:
+- ✅ Removed `test-calculations.js`
+- Test code kept in `TEST_REPORT.md` for reference
+
+---
+

+## Build Configuration
+
+The build should now pass without errors. If deployment still fails, check:
+
+1. **Node/npm versions**: Ensure compatible versions
+2. **Environment variables**: Check all required env vars are set
+3. **Build command**: Should be `vite build`
+4. **Dependencies**: Run `npm install` before building
+
+---
