Why flagged

The PKGBUILD downloads a prebuilt Windows MSI binary from cdn.raxxla.org, which is a CDN associated with the raxxla.org project (an Elite Dangerous companion tool), not an official software distribution channel like GitHub releases or a major package registry. The MSI is extracted and its contents (including a .exe) are installed into /opt and later executed via a wrapper script under Proton-GE. The integrity check uses only MD5 (weak, collision-prone) rather than SHA256/SHA512, and there are no PGP signatures. While raxxla.org appears to be a legitimate fan/community project for Elite Dangerous, the binary is sourced from a personal/project CDN with no cryptographic verification beyond a weak MD5 hash. This constitutes a genuine supply-chain concern: if cdn.raxxla.org is compromised or the file is silently replaced, users would execute arbitrary Windows PE code inside their Proton prefix. The risk is real but not clearly malicious — this is a medium-severity supply-chain concern.
