Why this verdict

PkgRadar discounts a release’s score when public reputation argues against novel malware. The verdict above already reflects these — the panel just explains what was applied.

Versions published: 22

Publisher: GitHub ActionsTrusted automation · −70% score

Effective trust discount applied: −70% (max across signals — discounts don’t stack). New install-lifecycle deltas vs the previous release would clear the discount.
