MI shown is the Visual Studio rescale (mi_visual_studio), clamped to 0–100: GOOD ≥ 20, MODERATE ≥ 10, else LOW. Large files commonly clamp to 0 — a property of the formula's range, not a meaningful score; rows are still ranked by the unclamped value so the order remains informative. The bca check gate may evaluate a different MI variant (mi.original or mi.sei), so its threshold is not directly comparable to this column.

Summary

Files: 402 | SLOC: 98,770 | PLOC: 51,370 | Comment ratio: 42.3%

Average MI (SLOC-weighted): 8.9 (LOW)

Actionable Summary

Advisory thresholds: sourced from the `bca.toml` `[thresholds]` table.

Raw counts across all functions; the hotspot tables hide suppressed rows (cyclomatic: 16, cognitive: 5, halstead: 6, nargs: 1, abc: 5) — re-run with --no-suppress to list them.

15 functions with CC > 15
7 functions with cognitive complexity > 15
36 functions with more than 5 parameters

Change-history risk

Bus factor

Bus factor: the number of authors whose departure would orphan more than half the files; lower is riskier.

Legend

Risk: Composite change-history risk score: recent churn and commit frequency dominate, raised by author dilution, bug-/security-fix history, and newness. Ordinal: only relative ranks carry meaning, not the absolute value.
Commits (recent): Distinct commits that touched this file in the recent window (default 90 days, set via --recent-window). Wire key: commits_recent.
Commits (long): Distinct commits that touched this file in the long window (default 365 days, set via --long-window) — not all history. Wire key: commits_long.
Churn (recent): Lines added + deleted to this file in the recent window (default 90 days, set via --recent-window). Wire key: churn_recent.
Churn (long): Lines added + deleted to this file in the long window (default 365 days, set via --long-window) — not all history. Wire key: churn_long.
Authors (recent): Distinct authors who touched this file in the recent window (default 90 days, set via --recent-window). Wire key: authors_recent.
Authors (long): Distinct authors who touched this file in the long window (default 365 days, set via --long-window) — not all history. Wire key: authors_long.
Ownership: Top-author edit share (0–1): fraction of edits by the single most active author; lower means more diluted ownership.
Burst: Recency of change (0–1): recent commits as a share of long-window commits.
Bug fixes: Commits classified as bug fixes (by message) within the long window.
Sec fixes: Commits classified as security fixes (by message) within the long window; weighted more heavily than bug fixes.
Reverts: Revert commits touching this file within the long window.
Age (d): Days since the first in-window commit touching this file (capped at the long window).
Last mod (d): Days since the most recent in-window commit touching this file.
Change entropy (recent): Change entropy (bits): how scattered the changes to this file are across commits (Hassan 2009), over the recent window (default 90 days, --recent-window). Higher means more diffuse, fault-prone change. Wire key: change_entropy_recent.
Change entropy (long): Change entropy (bits): how scattered the changes to this file are across commits (Hassan 2009), over the long window (default 365 days, --long-window). Higher means more diffuse, fault-prone change. Wire key: change_entropy_long.
Co-change entropy (recent): Co-change entropy (bits): how widely changes to this file ripple to other files, over the recent window (default 90 days, --recent-window). Higher means coupling to many different partners. Wire key: cochange_entropy_recent.
Co-change entropy (long): Co-change entropy (bits): how widely changes to this file ripple to other files, over the long window (default 365 days, --long-window). Higher means coupling to many different partners. Wire key: cochange_entropy_long.
Hotspot: Complexity × recent churn: high-complexity files that also change often. Shown only when AST metrics are joined (e.g. report --vcs); omitted by plain bca vcs.
Bus factor: Number of authors whose departure would orphan more than half the files (by Avelino Degree-of-Authorship); lower is riskier.
Files: Files in this directory contributing to its bus factor.
