Project health

A signal about how the project is maintained — not a vulnerability in your code. It doesn’t affect the verdict above.

Project health — OpenSSF Scorecardⓘ didn’t run

Maintenance & supply-chain hygiene. A signal about the project, not a vulnerability in your code.

This check didn’t finish — that’s not the same as “clean.” Try Check again above.

via OpenSSF Scorecard · Apache-2.0

About these results. Six open-source checks ran in parallel; every finding is tagged with the tool that produced it. The verdict follows a published rule. False positives and false negatives are normal — a clean scan does not mean the code is secure, and a red verdict does not mean the project is compromised.
