In Memory & Knowledge

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 →

Is LightMem safe?

Public trust evidence for LightMem 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 LightMem publish package provenance?

No published build provenance is currently detected for LightMem. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.

Does LightMem have an OpenSSF Scorecard?

LightMem has an OpenSSF Scorecard score of 2.6/10. 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 LightMem actively maintained?

Actively maintained. The repository was pushed to within the last 7 day(s).

What license does LightMem use?

LightMem ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are LightMem's commits signed?

64% of the last 100 commits to LightMem 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.
