Maintainer Checklist
Add Scorecard coverageExpose the repository to OpenSSF Scorecard checks so supply-chain posture is easier to verify.
How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade D reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Public trust evidence for Browser Harness is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.
Does Browser Harness publish package provenance?
Yes. Browser Harness's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does Browser Harness have an OpenSSF Scorecard?
No OpenSSF Scorecard data is currently published for Browser Harness. Maintainers can enable the Scorecard GitHub Action to get a public score; without it, automated supply-chain hygiene is harder for outsiders to verify.
Is Browser Harness actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Browser Harness use?
Browser Harness ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Browser Harness's commits signed?
52% of the last 100 commits to Browser 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 Browser Harness?
HVTrust scores Browser 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.
