Why flagged

The package downloads a prebuilt binary application (a .run installer containing a tar archive with executables) from a Macmillan Education production API endpoint (lms-api-prod-navio.macmillan.education). While this is the official vendor's own infrastructure (Macmillan Education is a major publisher), it is not a standard software distribution channel (no GitHub releases, no official Linux package repo). The PKGBUILD extracts a binary payload by stripping the installer header and unpacking nested tarballs, then installs a Mono-based application directly to /opt. The sha256sums are pinned, which mitigates interception risk. The custom DLAGENT with a referer header is unusual but functional. The main concern is that this is a closed-source binary from a CDN/API endpoint rather than a versioned release artifact, meaning the vendor could silently replace the binary at the same URL (though the checksum would catch that). This is a genuine medium-risk supply-chain pattern: executed proprietary binary from a non-standard vendor API host, not a clearly malicious or piracy scenario.

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, …).
