Repowise scores meridiona/meridian at 6.2 out of 10 for code health, which reads as fair, alongside maintainability 7.5 and static performance 9.6 on the same scale. There are 2,556 open findings across the three pillars, and the lowest-scoring file is mod.rs at 1.0. Scores are computed from complexity, duplication, churn and git fix history, not from a linter.
