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 0.15, CI runs tests; 0% of function code in complex or long functions; 6% duplicated lines. Weakest area: docs.
| Area | Score |
|---|---|
| Complexity (lizard) | 100 |
| Duplication | 71 |
| Code smells (Opengrep) | 100 |
| Tests and CI | 67 |
| Documentation | 65 |
| Type safety | n/a |
| Process (Scorecard review/maintenance) | n/a |
- Functions: 374; mean complexity 1.7, 90th percentile 3; 0 complex and 0 long functions
- Duplicated lines: 5.8% of 4,770 compared
- Tests: 1,128 test lines for 7,433 source lines (ratio 0.15); CI test commands: go test, cargo test; 11% of recent source commits also change tests
- Docs missing or thin: contributing, changelog
Security
Security posture is adequate: no high-impact findings. Weakest area: posture.
| Area | Score |
|---|---|
| Secrets (gitleaks, tree + history) | 100 |
| Static analysis (Opengrep) | 96 |
| Vulnerable dependencies (OSV) | n/a |
| CI workflows (zizmor) | n/a |
| Posture (policy, updates, signing, lockfiles) | 0 |
| OpenSSF Scorecard | n/a |
- Posture checks passed: none; missing: security policy, dependency updates, signed commits, lockfiles

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.
