## 🐛 KNOWN ISSUES & FIXES

### Issue 1: Qwen3.5:0.8B Vision Not Working in Ollama
**Status:** ⚠️ INVESTIGATING

**Problem:**
- Qwen3.5:0.8B officially supports vision (per official docs)
- Ollama model returns empty responses for image inputs
- Model loads and responds to text-only prompts

**Root Cause:**
- Ollama build of Qwen3.5:0.8B may not have vision encoder enabled
- Vision requires specific GGUF quantization with vision support

**Attempted Fixes:**
- ✅ Updated to Qwen3.5 vision-optimized parameters (temperature=0.7, top_p=0.8, top_k=20, presence_penalty=1.5)
- ✅ Changed image format to JPEG with 95% quality
- ✅ Added empty response detection

**Recommended Solutions:**
1. **Use larger Qwen3.5 variant**: `ollama pull qwen3.5:9b` (better vision support)
2. **Use LLaVA**: `ollama pull llava` (confirmed vision working)
3. **Wait for Ollama update**: Vision support may come in future Ollama release

**Files Updated:**
- `backend/agents/vision_agent.py` - Added vision-optimized parameters
- `test_vision.py` - Updated test with better diagnostics
- `app.py` - Added vision capability detection

### Issue 2: Vision Agent Model Check
**Problem:** `check_model_availability()` was failing even though Ollama was running
**Fix:** Added direct Ollama client connection test before vision analysis
**Status:** ✅ FIXED

### Issue 2: Category Enum/String Mismatch
**Problem:** `ImageAnalysis.category` is str but UI accessed `.value`
**Fix:** Added hasattr check to handle both cases
**Status:** ✅ FIXED

### Issue 3: Duplicate ExtractedImage Schema
**Problem:** Two `ExtractedImage` classes defined in schemas.py
**Fix:** Removed duplicate definition
**Status:** ✅ FIXED

### Issue 4: Media Extraction - No Images
**Problem:** Test ZIP had no embedded images in PDFs
**Note:** Not a bug - PDFs used for testing didn't have embedded images
**Workaround:** Use ZIPs with actual product photos or image files
