Coverage

  • Method v4, causari 0.4.1. Detection from commit metadata only; survival from git blame -w -M -C at HEAD.
  • Full clone: yes. Method v4 refuses shallow clones; this row comes from a complete history.
  • Sample: 61 AI-tagged commits; the sample floor is 5. At or above the floor, so the ratio is aggregated into the report.
  • PROBABLE: No PROBABLE commits: every counted commit carries machine-readable AI authorship metadata.
  • Cap: 743 lines per commit in this repository; the capped ratio is 85.0 %.
  • .git-blame-ignore-revs: not present in this repository.
