Hotspot Risk

Detekt · AtlasArc 1.0.1+736db9b9 · 2026-07-31T22:45:00Z

A risk-ranking report for complexity, coupling, visibility, and coverage hotspots.

Refactoring Risk Briefing

This chapter ranks package-level risk signals before the diagrams: coupling pressure, distance from the main sequence, visibility, cycle participation.

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.

Cycle status
  • 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.
