## Summary

- **Files needing attention**: 60
- **Current overall coverage**: 66%
- **Target coverage**: 95% per file
- **Generated**: Unknown

## Instructions

1. Check off completed test items by changing `[ ]` to `[x]`
2. Focus on files with lowest coverage percentages first
3. Add new test files in the appropriate `tests/` directory
4. Re-run coverage report to track progress: `cargo tarpaulin --out Json --lib`
