}Expand description
A hotspot: a file that is both complex and frequently changing.
§Score Formula
normalized_churn = weighted_commits / max_weighted_commits (0..1)
normalized_complexity = complexity_density / max_density (0..1)
score = normalized_churn × normalized_complexity × 100 (0..100)Score uses within-project max normalization. Higher score = higher risk. Fan-in is shown separately as “blast radius” — not baked into the score.
Fields§
§path: PathBufFile path (absolute; stripped to relative in output).
score: f64Hotspot score (0–100). Higher means more risk.
commits: u32Number of commits in the analysis window.
weighted_commits: f64Recency-weighted commit count (exponential decay, half-life 90 days).
lines_added: u32Total lines added across all commits.
lines_deleted: u32Total lines deleted across all commits.
complexity_density: f64Cyclomatic complexity / lines of code.
fan_in: usizeNumber of files that import this file (blast radius).
trend: ChurnTrendChurn trend: accelerating, stable, or cooling.
ownership: Option<OwnershipMetrics>Ownership signals (bus factor, contributors, declared owner, drift).
Populated only when --ownership is requested.
is_test_path: boolTrue when the file path matches a test/mock convention (e.g.
**/__tests__/**, **/*.test.*, **/*.spec.*, **/__mocks__/**).
Test files are intentionally included in hotspot ranking (test
maintenance IS real work), but tagging them lets consumers decide
whether to weight or filter them downstream.
