Why flagged

The package downloads a prebuilt AppImage executable from a non-whitelisted, non-standard host (release.liuyun.io), which is not the project's official release infrastructure, and uses 'SKIP' for checksums, creating an unverifiable supply-chain risk.

Triggered rules

Medium source=() URL on a non-standard host source_untrusted_domain

One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).
