Why flagged

The PKGBUILD downloads a prebuilt x86_64 binary ('wercker') from an Amazon S3 bucket (s3.amazonaws.com/downloads.wercker.com) and installs it directly as an executable. This is a legitimate pattern for the Wercker CLI — Wercker (acquired by Oracle) distributed its CLI as a prebuilt binary from this S3 bucket, and the URL structure matches the official distribution pattern. However, the concerns are real: (1) it is a prebuilt binary with no source build, so the supply chain cannot be audited; (2) Wercker/Oracle has since discontinued the product, meaning the S3 bucket may no longer be actively maintained or could be repurposed; (3) only MD5 and SHA256 checksums are provided — these verify integrity at packaging time but do not prove the binary was ever built from auditable source. The license is listed as 'unknown', which is a minor additional concern. The medium rating is appropriate: this is a real executed binary from a non-standard (S3 bucket) host with no source code, fitting the supply-chain risk profile, even if the original distribution was legitimate.
