S202 Quality Report

Overall Quality Score

The project needs focused structural attention. The most important findings should be planned explicitly instead of being handled opportunistically.

59of 100Needs Attention

Assessment Drivers

Project size is medium-sized with an average dependency density of 1.6 internal dependency edge(s) per class.
Package distribution is concentrated: the largest package contains 70 class(es), about 9% of the codebase.
Structural anomaly pressure is visible through 56 layered violation(s), 1 package cycle(s), and 10 class cycle(s).

Recommended Focus

Review the largest packages first; they are likely to dominate change cost and ownership.
Prioritize the highest-scoring package hierarchy violations and remove upward dependencies.
Use the generated cycle screenshots to identify stable cut points for package and class tangles.
