Code health
This codebase scores 4.0 out of 10 for code health, which we rate needs work. It also scores maintainability 4.3 and static performance 9.8 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 30 of 184 files are git hotspots, and they average 2.4 — which is where the fixes pay off most.

Small effort
Improve what Repowise can see
Add a test coverage report
Without one, Repowise cannot tell tested code from untested code, so every test-related action says “unknown”.
