Key Findings

HighCycles

5 problem cycle groups reported in this report scope.

NeutralCoupling

NCCD is 3.02. Use it as a same-project dependency-shape baseline; inspect cycles and concrete paths before interpreting a change.

WatchJVM public surface

ARV and GRV describe JVM public-surface breadth: ARV 0.74, GRV 0.72. This surface is broad enough to inspect against package roles, marked public classes, and real callers.

Highest-Value Targets

  • The report reads package structure and dependency evidence; it does not know what the code is meant to do.
  • Coverage metrics are not loaded, so coverage-dependent risk readings are unavailable.
  • Package exclusions are disabled for this report context.

What This Report Says

Cycle risk is the dominant signal

Read this report as cycle-first evidence: resolve or consciously accept the reported cycle groups before treating lower-level metrics as optimization work.

  • 5 problem cycle groups reported in this report scope.
  • First package to inspect: core-module.main:org.simplejavamail.internal.util (Architectural cycle participant, fan-in 27 / fan-out 4, distance 0.77, visibility 0.83).
  • Largest cycle group: Problem cycle 1 with 9 packages.

Evidence Summary

NCCD3.02

Same-project dependency-shape baseline; compare only on an equivalent analysis basis.

ARV0.74

Unweighted average of package Relative Visibility; each package contributes equally.

GRV0.72

Public JVM classes divided by all JVM classes across the graph.

Cycle groups5

Cycle clusters remain in the report scope.

Precise graph statistics remain available below so the report stays auditable.

Architecture Overview Focus

This profile reads the whole model first: cycle posture, highest inspection target, and any governance context that changes how warnings should be interpreted.

Cycle posture5 groups

Start by comparing the cycle map with the cycle groups table.

Primary inspection targetcore-module.main:org.simplejavamail.internal.util

Architectural cycle participant, fan-in 27 / fan-out 4, distance 0.77, visibility 0.83

Governance context0 Safe Havens / 0 debt records

Safe Havens, exclusions, and repository governance shape which findings remain active warnings.

Suggested Next Steps

1Start with Problem cycle 1

9 packages participate in this architectural cycle group. Use the cycle table and topology figure to decide whether to break the loop or record an explicit governance decision.

2Inspect core-module.main:org.simplejavamail.internal.util

This package has the strongest combined structural signal in the report scope: Architectural cycle participant, fan-in 27 / fan-out 4, distance 0.77, visibility 0.83.

Metric Notes

CCD, ACD, RACD, and NCCD describe structural graph shape. Package tables include fan-in, fan-out, instability, and line count. Dependency scope: compiled JVM dependencies. ARV is the unweighted average of package Relative Visibility; GRV is public JVM classes divided by all JVM classes across the graph. They describe public-surface breadth, not actual reachability or a universal architecture-health target.

Problem Cycles

Each card is one current problem strongly connected component. Every group gets one compact horizontal map. When additional maps are requested, a second map appears only when its focused architecture units or dependency edges strictly extend the compact evidence; layout-only duplicates are suppressed.

Problem Cycle Edges

These are the strongest currently reported problem-cycle edges. They are not fully covered by repository governance and are not removed by Safe Havens in this report scope. The Dependency refs value counts acquired class dependency references aggregated into each package-to-package edge; it is not a source line number.

Governed Cycle Context

Repository-governed dependencies stay structurally visible, but fully covered evidence does not keep problem-cycle warnings red. Debt remains distinct from intentional governance. The Dependency refs value counts acquired class dependency references aggregated into each package-to-package edge; it is not a source line number.

Subsystem-Level Architecture

Subsystem figures summarize boundary pressure, internal cohesion, and recursive architecture signals.

  • How to read this graph: each bubble is a visible architecture-boundary rollup. Right means more outgoing boundary dependencies; up means more incoming boundary dependencies; size is total class count.
  • Colour follows instability, so red means outgoing-heavy rather than automatically wrong. Use the figure to find boundary surfaces worth inspecting in Topology or Matrix.
  • Dashed rings mark expanded aggregate boundaries whose visible descendants are also present. Terminal packages or source folders remain valid boundaries and use their own metrics.

  • How to read this graph: each bubble is a visible architecture-boundary rollup. Right means more visible API surface; up and colour both follow abstractness; size is total class count.
  • This view highlights boundary shape, not direct defect risk. A top/right bubble may be a deliberate public contract area.
  • Dashed rings mark expanded aggregate boundaries whose visible descendants are also present. Terminal packages or source folders remain valid boundaries and use their own metrics.

  • How to read this graph: each bubble is a visible architecture-boundary rollup. Right means more fully contained package-cycle groups; up means the largest contained package cycle is larger; size is package count.
  • Only package cycles fully inside the boundary count here. Terminal-package class/file tangles remain separate Package Internals evidence in Topology. Use the cycle tables, Topology, or Matrix for concrete dependency edges and cross-boundary cycle context.
  • Dashed rings mark expanded aggregate boundaries whose visible descendants are also present. Terminal packages or source folders remain valid boundaries and use their own metrics.
