+## Recommendations
+
+### Immediate Actions (None Required)
+✅ **All production-critical TODOs have been resolved**
+
+### Short-Term (Next Sprint)
+1. **Phase 2 iOS Enhancements** (8 items)
+   - Focus on rolling window maintenance and TTL validation
+   - Add fetcher instances where needed
+   - Implement database statistics and metrics recording
+
+### Medium-Term (Next Quarter)
+1. **iOS TypeScript Bridge** (3 items)
+   - Implement iOS-specific initialization and permission handling
+2. **Android Integration** (4 items)
+   - Complete TimeSafariIntegrationManager integration
+   - Extract remaining logic from plugin
+
+### Long-Term (Future Phases)
+1. **Phase 3 Features** (2 items)
+   - Active DID integration configuration
+   - JWT-signed fetcher replacement
+2. **Tracking Enhancements** (1 item)
+   - Notify execution tracking
+
+### Documentation Cleanup
+1. **Archive Historical TODOs** (176 items)
+   - Many TODOs in `docs/_archive/` and historical documents
+   - Consider excluding archive directories from scan
+   - Update scan script to exclude `docs/_archive/` by default
+
+---
+
+## TODO Scan Script Improvements
+
+### Suggested Enhancements
+1. **Exclude Archive Directories**
+   - Add `docs/_archive/` to `EXCLUDE_DIR_NAMES`
+   - Reduces noise from historical documentation
+
+2. **Filter False Positives**
+   - Exclude TODOs in generated files (`docs/TODO-CLASSIFICATION.md`, `docs/todo-scan.json`)
+   - Exclude TODOs in template strings (e.g., markdown generation)
+
+3. **Priority Classification**
+   - Add priority tags to TODOs (e.g., `// TODO: [HIGH]`, `// TODO: [LOW]`)
+   - Generate priority breakdown in report
+
+4. **Phase Tracking**
+   - Detect Phase 2/3 markers in TODOs
+   - Group by phase for better planning

+## Conclusion
+
+The codebase is in **excellent shape** with respect to TODOs:
+
+✅ **Zero high-priority production TODOs**  
+✅ **All production-critical items resolved**  
+✅ **Remaining TODOs are well-scoped Phase 2/3 enhancements**  
+✅ **TypeScript code has zero TODOs**
+
+The 176 documentation TODOs are primarily historical references and don't impact production functionality. Consider excluding archive directories from future scans to reduce noise.
+
+**Next Steps:**
+1. Focus on Phase 2 iOS enhancements when ready
+2. Complete Android integration work
+3. Update TODO scan script to exclude archives
+4. Continue tracking remaining TODOs in project planning
