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: 41Mature · −50% score

Publisher: Chen chuan

Effective trust discount applied: −50% (max across signals — discounts don’t stack). New install-lifecycle deltas vs the previous release would clear the discount.
