Why flagged

The package downloads a prebuilt binary tarball from a non-whitelisted but project-owned domain (api.fluxer.app), which is not on standard hosting; if compromised, this could enable supply-chain attacks via trojaned binaries.

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, …).
