How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade B reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

Common questions about Better Harness

Public supply-chain signals for Better Harness are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but Better Harness carries less obvious unverified-evidence risk than projects with thin signals.
Does Better Harness publish package provenance?
Yes. Better Harness's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does Better Harness have an OpenSSF Scorecard?
Better Harness has an OpenSSF Scorecard score of 4.5/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.
Is Better Harness actively maintained?
Actively maintained. The repository was pushed to within the last 2 day(s).
What license does Better Harness use?
Better Harness ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Better Harness's commits signed?
10% of the last 100 commits to Better Harness are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.

Maintain Better Harness?

For maintainers

HVTrust scores Better Harness from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
