| # Deployment Verification — WebLLM CDN Fix | |
| ## Issue Summary | |
| **Problem:** GitHub Pages showed "OFFLINE" status, WebLLM not loading | |
| **Root Cause:** Commits were made locally but NOT pushed to GitHub | |
| **Fix Applied:** Pushed commits to origin/master | |
| **Result:** CDN fixes now live on GitHub Pages | |
| --- | |
| ## What Changed | |
| ### Commits Pushed to GitHub | |
| ``` | |
| 213d21a fix: Add WebLLM CDN fallback and robust loading checks | |
| ebf2743 feat: Frontend audit complete — production readiness 100% | |
| ``` | |
| ### Files Updated | |
| 1. **index-app.html** | |
| - Added dual CDN configuration (jsDelivr + unpkg fallback) | |
| - Added status tracking: window.webllmReady, window.webllmError, window.webllmCDNLoading | |
| - Auto-fallback logic when primary CDN fails | |
| 2. **js/ahmad-jit-ui.js** | |
| - Added WebLLM availability check in loadModel() | |
| - User messages if CDN still loading or failed | |
| - Graceful error handling | |
| 3. **js/ahmad-jit-engine.js** | |
| - Enhanced error messages with CDN status | |
| - Better console logging | |

| ## Verification Steps (Do This Now) | |
| ### Step 1: Hard Refresh GitHub Pages | |
| 1. Open: https://snapkittywest.github.io/rowm-polymorphic-notebook/index-app.html | |
| 2. Hard refresh: **Ctrl+Shift+R** (Windows) or **Cmd+Shift+R** (Mac) | |
| 3. Wait for page to fully load (2-3 seconds) | |
| ### Step 2: Check Console (F12) | |
| Open browser console (F12) and look for: | |
| ```javascript | |
| // Expected console output: | |
| Ahmad JIT UI initialized successfully | |
| Page ready. WebLLM CDN is loading... | |
| WebLLM loaded from jsDelivr | |
| // OR if fallback needed: | |
| WebLLM loaded from unpkg | |
| ``` | |
| ### Step 3: Verify Global Variables | |
| Paste these in console: | |
| ```javascript | |
| console.log('window.webllm:', typeof window.webllm); // Should be: object | |
| console.log('window.webllmReady:', window.webllmReady); // Should be: true | |
| console.log('window.webllmError:', window.webllmError); // Should be: null | |
| console.log('window.webllmCDNLoading:', window.webllmCDNLoading); // Should be: false | |
| ``` | |
| **Expected Output:** | |
| ``` | |
| window.webllm: object | |
| window.webllmReady: true | |
| window.webllmError: null | |
| window.webllmCDNLoading: false | |
| ``` | |
| ### Step 4: Check Network (DevTools Network Tab) | |
| 1. Open DevTools > Network tab | |
| 2. Reload page | |
| 3. Look for these requests: | |
| ``` | |
| cdn.jsdelivr.net/npm/@mlc-ai/web-llm@0.2.32/dist/web-llm.js | |
| Status: 200 (success) or 304 (cached from browser) | |
| ``` | |
| If jsDelivr fails (404, timeout), you should also see: | |
| ``` | |
| unpkg.com/@mlc-ai/web-llm@0.2.32/dist/web-llm.js | |
| Status: 200 (fallback success) | |
| ``` | |
| ### Step 5: Test Model Loading | |
| 1. Look at Ahmad Bot box (centered on page) | |
| 2. Status should show: **OFFLINE** (in red) | |
| 3. Button should say: **LOAD LOCAL MODEL** | |
| 4. Click the button | |
| 5. System messages appear: | |
| - "Initializing WebLLM engine and downloading model (500MB+)..." | |
| - "This may take 1-5 minutes on first load..." | |
| 6. Wait 1-5 minutes for model download | |
| 7. Status should change to: **READY** (in green) | |
| 8. Try sending a message - response should stream | |

| ## Troubleshooting | |
| ### Issue: Still Shows OFFLINE | |
| **Check 1: GitHub Pages Deployed?** | |
| ```bash | |
| # In terminal: | |
| cd rowm-polymorphic-notebook | |
| git log --oneline -1 origin/master | |
| # Should show: 213d21a fix: Add WebLLM CDN fallback... | |
| ``` | |
| **Check 2: Page Cache** | |
| - Hard refresh: Ctrl+Shift+R (Windows) / Cmd+Shift+R (Mac) | |
| - Clear browser cache: DevTools > Settings > Network > Disable cache | |
| **Check 3: CDN Loading** | |
| - Console should show: "WebLLM loaded from jsDelivr" or "WebLLM loaded from unpkg" | |
| - If not, check Network tab for CDN requests | |
| ### Issue: Network Error Loading CDN | |
| **Option 1: Check Internet** | |
| - Open any website to verify connection works | |
| - Try different browser (Chrome, Firefox, Safari) | |
| **Option 2: Check Corporate Network** | |
| - Some networks block CDNs | |
| - Try on phone hotspot or personal WiFi | |
| **Option 3: CDN Down** | |
| - Both jsDelivr and unpkg down simultaneously (extremely rare) | |
| - Wait a few minutes and try again | |
| ### Issue: Model Download Very Slow | |
| **This is Normal:** | |
| - First download is 500MB (takes 1-5 minutes) | |
| - After first load, model is cached | |
| - Subsequent visits are instant | |

| ## Expected Behavior After Fix | |
| ### Scenario: Page Load (Normal Case) | |
| ``` | |
| 1. User opens: https://snapkittywest.github.io/rowm-polymorphic-notebook/index-app.html | |
| 2. Console: "Ahmad JIT UI initialized successfully" | |
| 3. jsDelivr CDN loads WebLLM (2-3 seconds) | |
| 4. Console: "WebLLM loaded from jsDelivr" | |
| 5. Ahmad Bot status changes: OFFLINE → (shows status badge) | |
| 6. Button enabled: "LOAD LOCAL MODEL" | |
| 7. User clicks button | |
| 8. Model downloads (1-5 minutes) | |
| 9. Console: "Model loaded: Qwen2-0.5B-Instruct-q4f32_1-MLC" | |
| 10. Ahmad Bot status: LOADING → READY | |
| 11. Chat enabled, can send messages | |
| ``` | |
| ### Scenario: jsDelivr Fails (Fallback Case) | |
| ``` | |
| 1-4. Same as above but jsDelivr fails | |
| 5. onerror fires, loadWebLLMFallback() called | |
| 6. unpkg CDN loads WebLLM | |
| 7. Console: "WebLLM loaded from unpkg" | |
| 8-11. Same as normal case | |
| ``` | |
| ### Scenario: User Clicks Before CDN Loads | |
| ``` | |
| 1. User opens page | |
| 2. Clicks "LOAD LOCAL MODEL" before CDN loads (2-3 sec) | |
| 3. Chat shows: "WebLLM library is still loading from CDN. Please wait a moment and try again." | |
| 4. Button re-enabled | |
| 5. User waits 3-5 seconds | |
| 6. Clicks again | |
| 7. This time CDN is ready, model loads successfully | |
| ``` | |
