Code health
This codebase scores 6.9 out of 10 for code health, which we rate fair. It also scores maintainability 7.7 and static performance 9.7 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 693 of 10,273 files are git hotspots, and they average 4.1 — which is where the fixes pay off most.
Do next
1 thing worth doing this quarter.
Worth planning
Delete 349 unused symbols and files (3,007 lines)
Nothing in the graph reaches them, across 44 files; every reader and agent pays to skip them.

Medium 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”.
- line coverage
- Unknown, no report
Small effortReview the 38 proposed decisions
None is accepted yet, so nothing can drift from one and agents get no enforced guidance from them.
