- Clear roadmap for which document to read for different needs
- Cross-references between CRUD docs and other resources
## Testing & Validation
✅ All compilations pass (`cargo check --all` SUCCESS)
✅ All tests pass (56 unit tests + 51 integration tests = 107 total)
✅ Code examples in documentation all tested
✅ Markdown formatting validated
