|-------|-------|
| `VersionStatus` | `VersionState` |
| `version_status(repo, scope)` | `verify_version(repo, scope)` |
| `detect_language_by_files` | `config_file::detect_language` |
| `read_all_config_versions` | `config_file::read_config_versions` |
| `source::git::*` (整个模块) | `source::git_tag` + `source::config_file` |
