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 adequate: test-to-source ratio 0.05, no CI test run detected; 0% of function code in complex or long functions; 2% duplicated lines. Weakest area: testing.

| Process (Scorecard review/maintenance) | n/a |
- Functions: 127; mean complexity 1.6, 90th percentile 3; 0 complex and 0 long functions
- Duplicated lines: 1.8% of 1,294 compared
- Tests: 104 test lines for 2,208 source lines (ratio 0.05); CI test commands: none detected; 21% of recent source commits also change tests
- Docs missing or thin: contributing, changelog

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.
