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 strong: test-to-source ratio 2.97, no CI test run detected; 0% of function code in complex or long functions; 0% duplicated lines. Weakest area: process.
| Area | Score |
|---|---|
| Complexity (lizard) | 100 |
| Duplication | 100 |
| Code smells (Opengrep) | 100 |
| Tests and CI | 70 |
| Documentation | 85 |
| Type safety | n/a |
| Process (Scorecard review/maintenance) | 15 |
- Functions: 20; mean complexity 2.2, 90th percentile 4; 0 complex and 0 long functions
- Duplicated lines: 0.0% of 143 compared
- Tests: 711 test lines for 239 source lines (ratio 2.97); CI test commands: none detected; 34% of recent source commits also change tests
- Docs missing or thin: contributing
Security
Security posture is adequate: no high-impact findings. Weakest area: posture.
| Area | Score |
|---|---|
| Secrets (gitleaks, tree + history) | 100 |
| Static analysis (Opengrep) | 100 |
| Vulnerable dependencies (OSV) | n/a |
| CI workflows (zizmor) | n/a |
| Posture (policy, updates, signing, lockfiles) | 0 |
| OpenSSF Scorecard | 25 |
- Posture checks passed: none; missing: security policy, dependency updates, signed commits, lockfiles
- OpenSSF Scorecard aggregate: 2.5/10 (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.
