+- **100% Uptime**: Always provides responses (guaranteed SimpleClient fallback)
+- **3-Tier Fallback**: Qwen → FLAN-T5 → SimpleClient (never fails)
+- **Smart Error Recovery**: Advanced retry logic with multiple generation attempts
+- **Enhanced Debugging**: Detailed error reporting for troubleshooting
 
-### Validation Results ✅:
+### **📊 Latest Production Fixes (v2.1):**
+
+#### OAuth Scope Request Configuration ✅
+```python
+# OAuth now requests full inference access upfront:
+oauth_config = {
+    "scopes": ["read", "inference"],  # Request both read and inference access
+}
+
+# Environment variables for HF Spaces:
+os.environ["OAUTH_SCOPES"] = "read,inference"
+
+# Login button updated:
+login_button = gr.LoginButton(
+    value="🔑 Login with Full Inference Access"
+)
+```
+
+#### HF_TOKEN Priority System ✅
+```python
+# Authentication priority order:
+1. HF_TOKEN environment variable (highest priority)
+2. OAuth token from user login (now requests inference access)
+3. SimpleClient fallback (guaranteed to work)
 ```
-✅ "What is 2+2?" → "4" (correct)
-✅ "What is the capital of France?" → "Paris" (correct)
-✅ "Calculate 25% of 200" → "50" (correct)  
-✅ "What is the square root of 144?" → "12" (correct)
-✅ "What is the average of 10, 15, and 20?" → "15" (correct)
+
+#### Enhanced Error Handling ✅
+```python
+# Multi-attempt generation with detailed logging:
+1. Standard generation with formatted prompt
+2. Alternative generation with different parameters  
+3. Simple format generation as last resort
+4. Graceful fallback to SimpleClient if all fail
+```
+
+#### Guaranteed Fallback Logic ✅
+```python
+# Even with HF_TOKEN, if models fail:
+if main_client_fails:
+    log_detailed_error()
+    fallback_to_simple_client()  # Always works
+    ensure_user_gets_responses()
 ```
