Coverage

  • Method v3, causari 0.3.0. Detection from commit metadata only; survival from git blame -w -M -C at HEAD.
  • Full clone: yes. Method v3 refuses shallow clones; this row comes from a complete history.
  • Sample: 155 AI-tagged commits; the sample floor is 5. At or above the floor, so the ratio is aggregated into the report.
  • PROBABLE: 4 PROBABLE commits (163 lines introduced, 140 still at HEAD) are listed here and never summed into the VERIFIED counts.
  • Cap: 717 lines per commit in this repository; the capped ratio is 65.5 %.
  • .git-blame-ignore-revs: not present in this repository.
