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 0.19, CI runs tests; 17% of function code in complex or long functions; 4% duplicated lines. Weakest area: process.
| Area | Score |
|---|---|
| Complexity (lizard) | 60 |
| Duplication | 79 |
| Code smells (Opengrep) | 89 |
| Tests and CI | 84 |
| Documentation | 100 |
| Type safety | 40 |
| Process (Scorecard review/maintenance) | 0 |
- Functions: 7,343; mean complexity 2.5, 90th percentile 5; 111 complex and 66 long functions
- Duplicated lines: 3.9% of 103,638 compared
- Tests: 26,430 test lines for 139,317 source lines (ratio 0.19); CI test commands: go test, cargo test; 52% of recent source commits also change tests
- Docs missing or thin: none
Most complex functions:
- main in scripts/desktop-run.py: complexity 229, 354 lines
- emit in crates/pebbles-gpu/src/prepare/mod.rs: complexity 175, 542 lines
