Subject Dependency Edges

Inbound and outbound edges show where the selected subject is used from outside and what it depends on outside its subtree. The Dependency refs value counts acquired class dependency references aggregated into each package-to-package edge; it is not a source line number.

Structural Map

Topology, cycle-only topology, and Matrix figures show broad packages structure and cycle evidence from complementary angles.

Rendered as Topology · Pinned Subject Open

Which subject-perimeter packages and dependencies surround the selected subject?

Configuration

Focus: jvm:module/spring-boot-build.core.spring-boot.main/package/org.springframework.boot.context.properties.source
Filter: All visible packages
Heatmap: Off
View intent: Pinned subject

Encoding

Nodes: Selected subject, subject descendants, perimeter neighbours, and orientation folders
Edges: Subject boundary crossings plus neighbour-context dependencies
Border colour: Cycle, Safe Haven, intentional governance, and debt status from the model

Use Direction, Neighbour links, and Mute cycles in the live Graph when you need to alternate between local blast-radius and ingress/egress readings.

Rendered as Topology · Cycles Only Open

Which cycle warnings remain when non-cycle dependency structure is stripped away?

Configuration

Focus: jvm:module/spring-boot-build.core.spring-boot.main/package/org.springframework.boot.context.properties.source
Filter: Cycles only
Heatmap: Off

Encoding

Nodes: Only packages needed to show reported cycle evidence
Edges: Cycle-participating dependencies after governance rules are applied
Border colour: Problem, Safe Haven, intentional governance, and debt cycle status

Use this beside the normal topology to distinguish broad structure from cycle-specific evidence.

Rendered as Dependency Matrix · Pinned Subject Open

How does the selected subject exchange dependencies with its perimeter?

Configuration

Focus: jvm:module/spring-boot-build.core.spring-boot.main/package/org.springframework.boot.context.properties.source
Filter: All visible packages
Heatmap: Off
View intent: Pinned subject

Encoding

Rows: Selected subject, descendants, and perimeter neighbours
Columns: Selected subject, descendants, and perimeter neighbours
Cells: Dependency count with boundary and context styling where applicable

Subject row/column traffic is primary; neighbour-neighbour cells provide surrounding context.

⚠️

Matrix hidden — 132 packages

The visible graph has 132 packages, which exceeds the safety and report-legibility limit of 100. Rendering a matrix this large may hang the browser or become unreadable when fitted to a report page. Raise the limit in Settings → Matrix → Max packages to render, or use the Focus filter to narrow the graph first.

Package Hotspots

Hotspot figures rank packages by available metric-space risk signals such as coupling and complexity.

Rendered as Hotspots · Coupling Open

Which leaf packages stand out by coupling pressure?

Configuration

Items: Leaf packages
Focus: jvm:module/spring-boot-build.core.spring-boot.main/package/org.springframework.boot.context.properties.source
Scope: Recursive
Preset: Coupling

Encoding

Bubble: One leaf package
X axis: Fan-out
Y axis: Fan-in
Size: Lines of code
Colour: Instability

Labels are shown for the largest report bubbles; inspect the package metrics table for the full ranked list.

Rendered as Hotspots · Visibility Open

Which leaf packages are visible to many callers and far from the main sequence?

Configuration

Items: Leaf packages
Focus: jvm:module/spring-boot-build.core.spring-boot.main/package/org.springframework.boot.context.properties.source
Scope: Recursive
Preset: Visibility

Encoding

Bubble: One leaf package
X axis: Relative visibility
Y axis: Fan-in
Size: Classes
Colour: Distance from main sequence

Labels are shown for the largest report bubbles; inspect the package metrics table for the full ranked list.

Rendered as Hotspots · Abstractness / Instability Open

Which leaf packages sit far from the main sequence?

Configuration

Items: Leaf packages
Focus: jvm:module/spring-boot-build.core.spring-boot.main/package/org.springframework.boot.context.properties.source
Scope: Recursive
Preset: Zone Map

Encoding

Bubble: One leaf package
X axis: Instability
Y axis: Abstractness
Size: Distance from main sequence
Colour: Distance from main sequence

Labels are shown for the largest report bubbles; inspect the package metrics table for the full ranked list.

Package Metrics

This table ranks packages by structural signals. Use it to inspect packages that combine high fan-in, high fan-out, cycle membership or size.

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.
