MEDIUM

Why flagged This PKGBUILD downloads a prebuilt binary from polytope.com (the vendor's own domain, not GitHub releases or a recognized package mirror) and installs it directly as an executable. While polytope.com appears to be the official vendor domain (matching the GitHub org polytopelabs), the binary is not sourced from a verifiable, immutable release artifact (e.g., GitHub releases with a tagged commit). The sha256sum provides integrity checking against the current file, but the host can silently replace the binary at any time without changing the URL. This is a classic supply-chain risk: a prebuilt, closed-source binary from a personal/vendor web server with no reproducibility guarantee. The risk is real but not clearly malicious — consistent with a MEDIUM rating.
