AI provenance describes how code was produced; it is not a quality judgment. Unless attribution is explicit, these are signals consistent with AI generation, not proof. Squash/rebase workflows, imported code, and rewritten history reduce accuracy.
Code quality
Code quality is weak: test-to-source ratio 0.00, no CI test run detected; 72% of function code in complex or long functions; 3% duplicated lines. Weakest area: complexity.
| Area | Score |
|---|---|
| Complexity (lizard) | 12 |
| Duplication | 83 |
| Code smells (Opengrep) | 100 |
| Tests and CI | 15 |
| Documentation | 80 |
| Type safety | 40 |
| Process (Scorecard review/maintenance) | 100 |
- Functions: 6; mean complexity 17.3, 90th percentile 57; 2 complex and 0 long functions
- Duplicated lines: 3.2% of 440 compared
- Tests: 0 test lines for 605 source lines (ratio 0.00); CI test commands: none detected; 0% of recent source commits also change tests
- Docs missing or thin: changelog
Most complex functions:
- lint_file in scripts/rtl_ltr_linter.py: complexity 57, 94 lines
- main in scripts/rtl_ltr_linter.py: complexity 27, 72 lines
Security
Security posture is weak: 23 high-severity workflow issues. Weakest area: ci actions.
| Area | Score |
|---|---|
| Secrets (gitleaks, tree + history) | 100 |
| Static analysis (Opengrep) | 100 |
| Vulnerable dependencies (OSV) | n/a |
| CI workflows (zizmor) | 1 |
| Posture (policy, updates, signing, lockfiles) | 60 |
| OpenSSF Scorecard | 29 |
- Posture checks passed: dependency updates, signed commits, lockfiles; missing: security policy
- OpenSSF Scorecard aggregate: 4.8/10 (published 2026-11-09)

Static signals only: the scorer never runs the project's code. Secret findings are pattern matches that were not verified, and secret values are never stored.
Distribution signals
- readme-download-lure: links to file hosts or shorteners: t.me/
Signals consistent with a repository that exists to distribute a download. They are heuristics, not a verdict; release files were not downloaded or inspected.
