Validation-report metrics: does HEAD’s structural risk predict where the mined defects landed? Presentation follows the project’s honesty framing — association, not causation; every number carries its n.

Fields

band_table: Vec<(String, u32, f64)>

(band, defect_changes, share) — share of defect-introducing changes that landed in files at each code-health band at the time.

auc_default: Option<f64>

AUC of HEAD’s structural_risk against the defect-implicated-file labels, using the default (untuned) weights. None when either class (implicated / not) is empty.

precision_at_10: Option<f64>

Precision among the 10 highest-risk files. None when fewer than 10 files have health data.

precision_at_red: Option<f64>

Precision among the files banded red at HEAD. None when zero files are red.

implicated_files: u32

Distinct files touched by at least one defect-introducing commit.

linked_defects: u32

Distinct defect-introducing commits (the SZZ links’ defect side, deduplicated).

sample_dates: Vec<String>

RFC 3339 dates of the historical band-scan samples used to look up “health at the time” for each defect-introducing commit.

excluded_no_data: u32

Defect-introducing commits excluded because no health sample existed at or before their date (and none is the earliest sample either).
