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.

Weekly downloads: 2,028Niche · −30% score
Versions published: 598Established · −30% score
First published: Aug 2025

Effective trust discount applied: −30% (max across signals — discounts don’t stack). New install-lifecycle deltas vs the previous release would clear the discount.
