Configuration + +Example configuration file (`scaffold.json`): + +```json +{ + "exclude_patterns": [ + ".git", + "__pycache__", + "*.pyc", + "node_modules" + ], + "checkpoint_interval": 100, + "output_dir": "./scaffold_output" +} +``` + +## Troubleshooting + +### Common Issues + +**Issue**: Files have different hashes on different systems + +**Solution**: Ensure all files use LF line endings and UTF-8 encoding. The canonicalizer handles this automatically. + +**Issue**: Manifest generation is slow for large repos + +**Solution**: Adjust `checkpoint_interval` in configuration. Check logs for progress. + +**Issue**: Merkle tree verification fails + +**Solution**: Ensure files haven't been modified since tree construction. Use `verify` command to check integrity. + +**Issue**: XML files produce different hashes on different Python versions + +**Solution**: Upgrade to Python 3.8+ for consistent XML canonicalization. The scaffold will display a warning if using older Python versions. + +**Issue**: Need custom handling clamps for different game versions + +**Solution**: Create a JSON config file with your clamp values and use `--config` flag with handling-clamp command. + +## Safety Features + +### Restore Command Safety + +The restore command includes multiple safety checks: +- Detects git repositories and checks for uncommitted changes +- Blocks restore if uncommitted changes are found +- Displays file count before deletion +- Requires typing 'DELETE' to confirm +- Requires second y/N confirmation +- Shows prominent warnings about permanent deletion + +### Python Version Requirements + +- **Python 3.6+**: Basic functionality +- **Python 3.8+**: Recommended for consistent XML canonicalization + +## Version History + +- **1.0.1** (2026-02-17): Code review updates + - Configurable handling clamps via JSON file + - Enhanced restore command safety + - Improved XML canonicalization documentation + +- **1.0.0** (2026-02-16): Initial release + - Canonicalization module + - Hashing module + - Merkle tree module + - Manifest generation + - JSONL logging + - GTA handling pipeline + - CLI with all subcommands + +## License + +MIT License - See repository LICENSE file + +## Contributing + +This scaffold is part of the Orthogonal Engineering methodology.
