+## Build & Test Results
+
+### Build: ✅ Success
+```
+✅ background.js: 2.73 KB (minified)
+✅ popup.js: 6.71 KB (minified)
+✅ tracking.js: 3.53 KB (minified)
+✅ All assets copied correctly
+✅ Zero build errors
+```
+
+### Tests: ✅ All Passing
+```
+✅ 22 tests passed
+✅ 0 tests failed
+✅ Test coverage: crypto, pdf-detector, tracker, binect-api
+```
+
+### Linting: ✅ Clean
+```
+✅ 0 errors
+⚠️  6 warnings (console statements in background script - acceptable)
+```
+
+## Next Steps for Deployment
+
+1. **Icons**: Replace placeholder icons with proper Binect-branded icons (SVG source recommended)
+2. **API Endpoint**: Verify Binect API endpoint URL and adjust if needed
+3. **Testing**: Manual testing in Chrome browser
+4. **Chrome Web Store**: Prepare for publication
+   - Create developer account
+   - Prepare screenshots
+   - Write store description
+   - Submit for review
+
+## Known Limitations (By Design)
+
+1. **PDF Detection**: Blob URLs and complex JavaScript viewers may not be detectable (documented in PRD)
+2. **Browser Support**: Chrome only in v1 (Manifest V3)
+3. **Encryption**: Not hardware-backed (acceptable for v1, documented in ADR-001)
