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. Full methodology →

Is Sim safe?

Sim has a mixed signal profile. Some trust indicators are present, others are missing. Whether it is safe for your use case depends on which gaps matter to you — review the breakdown below before adopting in production.
Does Sim publish package provenance?
No published build provenance is currently detected for Sim. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Sim have an OpenSSF Scorecard?
Sim has an OpenSSF Scorecard score of 5.7/10. 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 Sim actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Sim use?
Sim ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Sim's commits signed?
100% of the last 100 commits to Sim 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.

AI agent surface

Profile context only

HVTrust currently ranks supply-chain and project-integrity trust only. This public view shows a compact AI-agent surface snapshot from repo docs and manifests. These fields are descriptive context and do not affect the production HVTrust rank. An experimental local preview remains available in Score Lab →, and the policy boundary is tracked on the roadmap →

Maintain Sim?

HVTrust scores Sim 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.
