-## Next Steps
+- L68: **TODO** — - TODO: "Rewrite tests to use modern AndroidX testing framework"
 
-1. ✅ Complete TODO inventory scan
-2. ✅ Classify each TODO into one of the three categories
-3. **Create GitHub issues for "Must Ship" items** (7 issues needed)
-4. **Move "Phase 2" items to planning docs** or behind feature flags
-5. **Update code comments** to reflect classification and link to issues
-6. **Document Phase 2 features** in a dedicated planning document
