Overview

Package modularity implements the modularity metrics. The shared module-graph/history helpers live in internal/metrics/internal/modgraph.

Types

type BlastRadiusMetric

type BlastRadiusMetric struct{}

BlastRadiusMetric reports change-impact concentration: how many modules are "hubs" whose change forces a wide transitive rebuild, and which ones. It is a factual finding (report-only), not a quality verdict — a stable hub is fine. Volatility is the book's coupling_balance concern, not this metric's.

func (BlastRadiusMetric) Calculate

func (m BlastRadiusMetric) Calculate(in signal.CommonInput) diagnostic.MetricResult

Calculate computes per-module blast radius and reports the hubs above the threshold. Indeterminate (n/a) for graphs too small to have meaningful concentration.

func (BlastRadiusMetric) Name

func (m BlastRadiusMetric) Name() string

Name returns "blast_radius".

func (BlastRadiusMetric) Version

func (m BlastRadiusMetric) Version() string

Version returns "blast_radius.v1".
