Why flagged

This PKGBUILD downloads and installs a prebuilt binary tarball from silvercoders.com, which is the official vendor website for the DocToText product. The URL pattern and product page match the upstream vendor. However, the concern is real: a prebuilt binary (not source-built) is fetched from a small commercial vendor's own server over plain HTTP (no TLS), and installed directly into /opt. The sha256sums provide integrity checking, which mitigates substitution attacks somewhat, but the HTTP download means the checksum itself could be bypassed by a MITM if the PKGBUILD were modified. The binary is executed at runtime as a document converter. This is a classic medium-risk pattern: an executed binary from a non-major distribution platform (even if it is the legitimate vendor), installed without source verification. Not clearly malicious, but a genuine supply-chain concern given the non-HTTPS download and opaque prebuilt binary.
