MetricsEngine

object MetricsEngine(source)

Computes architecture health metrics for a ModuleDependencyGraph.

This file defines the data contracts now so the JSON baseline format is stable before metrics are fully implemented.

Metrics computed per build:

Afferent/efferent coupling (Ca/Ce) per module
Instability index (Ce / (Ca + Ce))
Abstractness (not computable from the graph alone - needs KSP in v1.0)
Distance from the main sequence (|A + I - 1|)
Project-wide coupling factor

Functions

computeModuleMetrics

fun computeModuleMetrics(graph: ModuleDependencyGraph): List<ModuleMetrics>

Computes per-module metrics for all modules in the graph.

computeProjectMetrics

fun computeProjectMetrics(graph: ModuleDependencyGraph): ProjectMetrics

Computes project-wide aggregate metrics.
