Scores
| Pillar | Score | Signal | Confidence | Coverage |
|---|---|---|---|---|
| AI provenance (estimated AI-generated share) | 0 | none-detected | 55% | 100% |
| Code quality | 50 | weak | 90% | 100% |
| Security | 73 | adequate | 85% | 100% |
AI provenance
No AI attribution or AI-consistent velocity signals detected.
- Explicitly attributed share (lower bound): 0.0%
- Unattributed share in AI-consistent velocity bursts: 0.0%
- Estimated AI-generated share: 0.0%
| Month | Lines added | Attributed to AI |
|---|---|---|
| 2013-04 | 1,102 | 0% |
| 2013-06 | 710 | 0% |
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; 0% of function code in complex or long functions; 16% duplicated lines. Weakest area: testing.
| Area | Score |
|---|---|
| Complexity (lizard) | 100 |
| Duplication | 38 |
| Code smells (Opengrep) | 100 |
| Tests and CI | 0 |
| Documentation | 65 |
| Type safety | n/a |
| Process (Scorecard review/maintenance) | 5 |
- Functions: 55; mean complexity 1.9, 90th percentile 3; 0 complex and 0 long functions
- Duplicated lines: 16.0% of 449 compared
- Tests: 0 test lines for 664 source lines (ratio 0.00); CI test commands: none detected; 0% 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) | 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: 2.1/10 (published 2026-10-26)
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.
