+- `requirements.md` - Formal requirements specification
+- `design.md` - Technical design document
+- `tasks.md` - Implementation task list
+
+### Reference Documentation
+- `codebase-mapping.md` - Map of codebase structure
+- `functional-requirements.md` - Functional requirements analysis
+- `evalq-usage-inventory.md` - Original evalq() usage inventory
+- `design-patterns.md` - Design patterns used
+
+### Developer Documentation
+- `developer-guide-extract-process-bind.md` - EPB pattern guide for developers
+- `refactoring-summary.md` - Comprehensive refactoring summary
+- `RELEASE-NOTES.md` - Release notes for version 1.2.1 (NEW)

+
+### Historical Documentation
+- `preparation-summary.md` - Initial preparation phase summary
+
+**Total Files Retained**: 17 essential documentation files
+
+## Documentation Updates
+
+### NEWS.md
+- ✓ Reviewed existing entry for version 1.2.1
+- ✓ Entry is comprehensive and accurate
+- ✓ References developer guide for details
+- ✓ No changes needed
+
+### DESCRIPTION
+- ✓ Version is 1.2.1.9000 (development version)
+- ✓ Appropriate for ongoing development
+- ✓ No version update needed at this time
+
+### New Documentation Created
+- ✓ `RELEASE-NOTES.md` - Comprehensive release notes document
+  - Overview of changes
+  - Benefits for users and developers
+  - Technical details
+  - Testing and performance validation
+  - Migration guide
+  - Quality assurance summary
+  - References and acknowledgments
+
+## Version Number Considerations
+
+### Current Version: 1.2.1.9000
+
+This is a development version indicating:
+- Base version: 1.2.1
+- Development suffix: .9000
+- Appropriate for ongoing development
+
+### Recommendation for Release
+
+When ready to release, the version should be updated to:
+- **1.2.1** - If releasing as a patch to 1.2.0
+- **1.3.0** - If releasing as a minor version with new features
+
+Since this refactoring is internal-only with no user-facing changes, **1.2.1** is appropriate.
+
+## Documentation Structure

+## Verification
+
+### Cleanup Verification
+- ✓ No debug scripts in root directory
+- ✓ No temporary benchmark scripts in spec directory
+- ✓ No checkpoint status files in spec directory
+- ✓ No task completion summaries in spec directory
+- ✓ Only essential documentation retained
+
+### Documentation Verification
+- ✓ NEWS.md entry is comprehensive
+- ✓ RELEASE-NOTES.md created with full details
+- ✓ Developer guide available for future contributors
+- ✓ All quality assurance documentation retained
+
+### Version Verification
+- ✓ DESCRIPTION version is appropriate (1.2.1.9000)
+- ✓ NEWS.md reflects version 1.2.1
+- ✓ Ready for release when appropriate
+
+## Next Steps
+
+### Before Release
+1. Review RELEASE-NOTES.md with maintainers
+2. Decide on final version number (1.2.1 recommended)
+3. Update DESCRIPTION version if needed
+4. Final review of NEWS.md entry
+5. Tag release in Git
+
+### After Release
+1. Update development version to 1.2.1.9001 or 1.3.0.9000
+2. Archive refactoring documentation if desired
+3. Update package website with new documentation
+
+## Success Criteria Met
+
+All success criteria for Task 31 have been met:
+
+- ✓ Removed temporary debug scripts
+- ✓ Removed temporary benchmark/validation scripts
+- ✓ Cleaned up checkpoint status files
+- ✓ Reviewed version number (appropriate as-is)
+- ✓ Finalized NEWS.md entry (already comprehensive)
+- ✓ Prepared release notes documenting internal changes
+
+## Conclusion
+
+The cleanup and documentation finalization is complete. The repository is now clean of temporary files, and comprehensive documentation is available for:
+
+- **Users**: NEWS.md entry explains internal changes don't affect them
+- **Developers**: Developer guide and refactoring summary provide full details
+- **Maintainers**: Release notes ready for version 1.2.1 release
+- **Future Contributors**: Clear documentation of EPB pattern and refactoring approach
+
+The Tplyr evalq() refactoring project is now complete and ready for release.
