Trust signals

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: 6,255Niche · −30% score
Versions published: 197
First published: May 2026
Publisher: jykim0507

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