+# Cast Iron Scout - Development Status
+
+**Last Updated:** April 9, 2026 - 5:50 PM  
+**Developer:** Forge
+
+## ✅ Completed
+
+- [x] Core scanner engine built
+- [x] Valuation engine with brand/size/type logic
+- [x] Telegram alert system
+- [x] Duplicate prevention (state tracking)
+- [x] Hourly cron job configured
+- [x] Configuration system
+- [x] Logging system
+
+## 🚧 In Progress
+
+### Channel: eBay
+- [x] RSS feed scanner (built)
+- [ ] HTML scraper (needed - RSS unreliable)
+- **Status:** ⚠️ RSS feeds not returning data consistently
+- **Next:** Implement proper HTML scraping with BeautifulSoup
+
+### Channel: Craigslist
+- [x] Scanner framework built
+- [ ] HTML parsing (in progress)
+- [ ] Multi-city scanning
+- **Status:** ⚠️ Returning 0 items - needs HTML structure fix
+- **Next:** Debug HTML parsing, add proper result extraction
+
+### Channel: Facebook Marketplace
+- [x] Scanner framework created
+- [ ] Selenium/Playwright implementation
+- [ ] Location-based searches
+- **Status:** 📝 Placeholder only (requires headless browser)
+- **Next:** Install Selenium, implement headless Chrome scraping
+
+### Channel: EstateSale.com
+- [ ] Not started
+- **Status:** ⏳ Backlog
+- **Next:** Research site structure, build scanner
+
+## 🔧 Technical Debt
+
+1. **eBay RSS unreliable** - Need HTML scraping
+2. **Craigslist HTML parsing** - Need to fix selector logic
+3. **Facebook requires Selenium** - Heavy dependency, slow scans
+4. **No image recognition yet** - Can't identify logos from photos
+5. **No price history database** - Can't track sold items
+
+## 📊 Performance
+
+- **Scan frequency:** Every hour
+- **Sources active:** 0/3 (all in development)
+- **Deals found:** 0 (no working sources yet)
+- **False positives:** N/A
+
+## 🎯 Next Steps (Priority Order)
+
+1. **Fix eBay scanner** - HTML scraping (2-3 hours)
+2. **Fix Craigslist scanner** - Debug HTML parsing (1 hour)
+3. **Add Facebook with Selenium** - Heavy lift (4-6 hours)
+4. **Test with real data** - Validate against manual searches
+5. **Add image recognition** - Logo identification (future)
+6. **Add sold items database** - Better FMV calculations (future)
+
+## 📝 Notes
+
+- Craigslist may block frequent requests - need rate limiting
+- Facebook Marketplace requires login for full access
+- eBay has official API but requires approval
+- Consider adding OfferUp, Letgo as lighter alternatives to FB
+

+
+**Current Focus:** Getting eBay and Craigslist working reliably  
+**ETA for First Deal Alert:** TBD (depends on scraping fixes)
